[Q] Very Odd installed appz after update <BRICKED>

Hoi Hoi people
i got myself a GT540 Optimus <yes total newbeee to android>
It came with a deal for free and its my 1st android :0
anyway
After USING the official way (silly me )to update I now have some odd Portuguese apps installed ? Stuff from SAPO.pt ???
I didn't do any Sync backup as i just got the phone and its basically empty
I used the Updater tool from LG connected and all went well But after I look I was able to change the language to ENG but it has quiet a few Portuguese Apps installed...
I am in Holland so i cannot see how this updater decided to give me a POR image ?
Now i could make a guess and say the IMEI is for Portuguese market(?) and the dutch INTERNET cheapo middleman I got the deal from has bought a bunch on the gray market ..
Whatever it is i don't care
I would like you guys now to point me the right way
I just flash the thing myself
I think the tool i need is called KDZ ?
Please someone point me to the right post I am looking but seem to get nowhere
just more confused
Thanks guys
B.T.W I am not too inept . I am used to flashin me HTC HD all the time ..

Toen je de officele lg updater gebruikte, welke taal was hij toen?
Het kan zijn dat je dat aan het begin verkeerd heb ingesteld.

Thanks a lot guys
I followed the hints and now my LG is dead ..
LOL
This is rather annoying
1st I get a Crap gray import from 2call
then LG puts a Portuguese update rom on it??WTF!>?
while i choose NETHERLANDS with language english
but nevermind
buy **** buy twice thats life
My 1st and last lg phone ?/
What kind of rubbish is this
u update using the official LG tool and they play a freckin foreign rom onto my LG (SAPO.PT) then I cant update it at all anymore using the tool . So i look for alternatives but thats just made it worse ...
Really really poor this ..
Now ...I followed the guide but it didn't work ..well it did until restarted
My lg is now black. Dead ! doesn't start up at all !
Doesn't start no-matter what i try !
not even emergency mode.
And no guys I read the instruction word for word !!!!
I followed it to the letter !!!!! and the update did work ..Just now it doesn't start at all anymore.
I should of known reading around
there are too many update ways people are doing this ..Hack tool or original KDZ ..or just Black system way ..Too many loopholes for things to go wrong ..but now too late

Hmm...
Try a reflash...
This is a guide I followed from another forum, and posted elsewhere with some minor additions in case anyone had problems.
The guide is from a forum post at the android forums,it is NOT my work, the added bits are mostly what I have found from browsing here and from asking questions. While I can't be held liable if you mess your phone up having done so myself I thought this could helpa few people and save them searching various threads for answers so hope it helps
The guide
To install this ROM you need to have fastboot enabled on your phone. If you have Android 1.6/2.1 installed from LG, then fastboot is not enabled. I will explain how to enable fastboot on your phone (this involves re-flashing/replacing your currently installed firmware):
I am unable to post links yet so you will have to copy and paste the appropriate link into your browser replacing the ** with tt
KDZ Updater Carphone Warehouse Unlocked.zip can be downloaded at h**p://goo.gl/7aRTc - A link to a zip archive with all the files needed to flash to Android version 2.1 with fastboot (Carphone Warehouse Unlocked)
KDZ Updater Europe Open.zip can be downloaded at h**p://goo.gl/BOcYT - A link to a zip archive with all the files needed to flash toAndroid version 2.1 with fastboot (Europe Open)
Download the version that best applies to you, if you live in the UK, I'd recommend you download the Carphone Warehouse Unlocked version, whereas if you live in Europe, I'd recommend the Europe Open version (simple right? )
I live in the UK and used the open rom from Europe as the Carphone Warehouse rom would not install
Now, how to flash these versions; I'll explain in detail how to flash the ROM's from starting with backing up.
Instructions to install ROM with Fastboot:
1. Before you start, make sure you backup all your data by installing the z4root.1.3.0.apk file onto your phone, then open it and choose 'Permanent Root'. Your phone will root and reboot. Then go to the Market and install 'MyBackup Root', open it and do a backup of your apps and personal data (contacts, sms, call log etc.) Once this is done, go to Settings>SD Card and Phone Storage>Unmount SD Card, a notification in the notification bar should appear saying 'SD Card safe to remove'. Remove the battery cover and remove the SD card and store it in a safe place. Then continue to step 2.
2. Extract the .zip file you downloaded to your computer (e.g. your desktop). Open the folder and install MSXML 4.0 SP3 Parser (msxml.msi).
3. Once that has finished, install LGAndroidDriver_WHQL_ML_Ver1.0_All_Win7.exe which are the drivers so your computer will recognize your phone.
4. Next, open KDZ_FW_UPD.exe
(i) Change 'Type' to '3GQCT' *THIS IS A MUST, THE UPDATE WILL NOT WORK OTHERWISE AND YOU MAY BRICK YOUR PHONE*
(ii) Make sure 'PhoneMode' is set to 'DIAG'
(iii) Browse for the 'V20B_00+Fastboot.kdz' file.
5. Prepare the phone by enabling USB Debugging by going to Settings>Applications>Development>Enable USB Debugging and connect the phone to the computer via USB cable and wait for the drivers to install for the phone.
6. Click 'Launch software update' and do not use your computer until the update is complete. The update will take roughly 10-20 mins to complete.
If you have a problem with this try a different rom, this guide offers two to choose from.
Instructions to install CyanogenMod:
Once the update is complete, your phone will reboot, what you need to do is power off the phone and whilst the phone is off, press and hold the 'Camera' button all the way ANDpower on the phone, make sure you hold the 'Camera' button. The phone will display the LG logo and disappear, then display a blank screen. The phone is now in fastboot mode!
Now you want to download this file: Flashing CyanogenMod.zip and extract it to a folder called 'Android' (without the quotes '') on the C: drive (you'll probably need to make this folder yourself.
1. Now open CMD with administrator privileges (Search for CMD in the start menu and right click on 'cmd' and click 'Run as Administrator' )
2. Connect the phone to your computer via USB cable and wait for the necessary drivers to install.
If when connected with a usb cable the computer says "waiting for device" and nothing else happens try installing the fastboot drivers. You can do this by going to the control panel of your pc, from the Windows start menu, opening the list of devices and where you see the one representing your phone (likely, as was the case with me, it will say android and have a yellow exclamation mark over it). Different versions of Windows do things slightly different but what you need to do is simply update the driver by choosing the icons properties box choosing UPDATE or INSTALL DRIVER and when asked pointing it to the folder where you unzipped the drivers.
3. Then go back to the cmd window and type:
Code:
cd C:\Android
(i) Then type:
Code:
fastboot.exe -w
(ii) Once that's completed, type:
Code:
fastboot.exe erase system
(iii) Once that's completed, type:
Code:
fastboot.exe flash system system.img
(iv) Once that's completed, type:
Code:
fastboot.exe flash boot boot.img
(v) Once that's completed, type:
Code:
fastboot.exe reboot
4. Your phone will now reboot with CyanogenMod 6.1.1 (Android 2.2.1). The first boot might take longer than a normal boot.
If your phone stays at a blank screen you simply forgot to do one of the above steps, in which case simply repeat them. It is likely if that happens that you simply forgot the flash boot image instruction.
5. You can now re-insert your SD card and go to Settings>SD Card and Phone Storage>Mount SD Card
Enjoy!
The instructions for flashing both the firmware with fastboot and flashing CyanogenMod are included in the zip archives called 'Readme'. I'll update the links so that you'll always have the most up to date version of CyanogenMod available for download, note that if you choose to update your phone you will loose all your data including apps etc. so backup before you update
And that, with a few comments added by myself, is the guide.
Once you have set your phone up the way you want power off your phone. Hold the HOME and POWER buttons down while the LG logo appears and you will see a menu appear on screen.
Using the volume down key to navigate the different menu choices, and the camera button to select an option choose the BACKUP OR RESTORE option and from the sub menu that it will give you choose BACKUP.
This will make a backup of your phone AND all your data, if you ever mess up an update or think you have damaged your phone in the future simply holdthe POWER and HOME buttons down and when the menu appears choose the RESTORE option

Dude
thanks a lot for your lengthy post and effort .I appreciate it .

MY LG doesn't even start anymore after using the Hack tool to upgrade it ...
SO its futile ??
I cant start the phone at all ...
After following yesterdays advice Its dead ..
Great init

Oh dang. Doesn't even turn on? No LG boot logo?
Well...if it's bricked...the only three ways are:
1) Get it repaired/replaced.
2) Buy a new phone.
3) Use it as a paperweight.
=)

No my friend ..its DEAD !!!!
following the guide to the letter
Installed parser got the hack tool
run all as admin and made sure I started windows enabler
All the things in the guide
worked a charm until reboot
Not its black and dead!!!

If you did it with kdz updater than:
pull out battery, sim and sd
connect phone with computer
disable lg modem in the device manager
flash a rom with fastboot
go in fastboot by camara+power
connect to computer
type 'fastboot -w' and 'fastboot reboot' in cmd

You can try by pulling out your battery, SIM card and SD card...
Note to you: Try everything that is possible and don't give up. Maybe you will fix it if you try.

And even that LG cant do without f&*kin me phone to Portuguese
So Well done LG )

[Q] Really could do with some help from those with experience... Please.

Hi Guys,
I am a noob to xda so please bear with me...
Hoping someone can help me out here.. I will try and explain in as much detail as possible and provide you with as much Info from my phone as I can.
Firstly my phones details
Motorola Atrix 4g (UK version) Second phone as busted the last one. Bought outright as a retail sale.
Orange UK
System Version: 45.31.0.MB860.Retail.en.GB
Android Version: 2.3.4 (After UK released update)
Baseband Version: N_01.100.00R
Webtop Version: WT-1.2.0.133_38
Kernel Version: 2.66.32.9 [email protected]#2
Ok so, decided to root my phone. To do so I used petesMotorolaRootTools_V1.07 found on the website psouza4.com/bionic/
This worked fine and an app installed from the App Market confirmed that the phone was Rooted and had Superuser permissions.
Next I downloaded ClockWorkMod Rom Manager from the Market Inc Premium, SetCPU, Rom Toolbox & Titanium Backup Free. I had a quick look at these apps once downloaded but didnt really do a lot,
However, when Rom Manager opened it promted me to Flash ClockWorkMod Recovery, Which I did and then selected Back up current Rom. I also did this, (bear with me it gets a little vague here as to what I remember seeing)
Now I'm sure it said something like Nandroid Backup, which I selected. It proceeded to say something along the lines of, Backing up or phone will now reboot??
Anyhow, what ever it said, it started to reboot. The Motorola Red Circle logo came up but then at the top it said reboot failed and something ilse that didnt make sense then froze. I pulled the battery and rebooted. Seemed to work fine. Maybe a touch laggy but nothing to bad.
Next did my research into what ROM I'm likely to want to try. Found a few but seemed from what I have read on various forums that they dont work well for uk phones. Then decided perhaps then flashing should be left alone and went back to PetesMotorolaTools and unrooted. before I unrooted however i removed all apps that required root access first. Possibly a mistake?
I noticed that a few preinstalled apps werent working, nothing important or anything I use but there icons were like Blue settings icons all the same.
Did a factory reset through the handset also, in an attempt to return to factory settings.. not much changed really. Also tried to update software though the Motorola website but it said I was all up to date.
I thought maybe that something went wrong so I rooted again. This time the unroot failed. I then dowloaded all the rooted apps that I had before and then unrooted. This worked. Not sure if coincedence or not but it worked and when unrooting it said unfreezing apps about 6 times, before the complete message. Then uninstalled the root apps again.
Most, not all but most of those preinstalled apps were then working ok.
I read a little bit more bout Roms and decided to have another bash. Found and downloaded a few to comp. Then I place an SD card into phone and Flashed it. then tranferred a copy to its root.
Rooted the phone in the same way as before. Downloaded all the apps again opened CWM RM, Flashed CWM Recovery again as was unsure that the time I did it before would work. Then selected back up Current ROM. Without any message this time the phone started to reboot.
It came up with the recovery screen (Android man and !) From what I have read the next step is to tap the bottom right of the screen to bring up the menu.
This did not work nor did anything else happen. After waiting about 25mins with nothing more happening I pulled the batt again.
Decided I'd boot into recovery mode manually and see if the bottom right of screen would work that way. turned off then held On and down Vol. Fastboot showed at top, Scrolled and selected Android recovery. Same Android Man and ! came up, tried tapping the bottom right of screen again.... It didnt work.
Read more on the forums where someone said that pushing up and down on the Vol buttons works. Tried this and hey presto.. a new menu appears. Shown as follows.
Android system recovery <3e>
Android system recovery utility
reboot system now
apply update from sdcard
wipe data/factory reset
wipe cache partition
No back up options so rebooted....
Anyway thought I'd try a few times to use CWM RM to flash a rom to device. Each time it took me throught this same process.
Eventually I though what the hec just try and flash it...
So I selected the apply update from sdcard option.
Then selected the ROM I saved to SD Card.
Then the following text appears on screen in yellow.
--Install /sdcard...
finding update package...
Openeing update package...
Verifying update package...
E:signature verification failed
Installation abborted
I tried this a few times to no avail. even tried downloading the roms from CWM RM with no change.
Read some more on the forums and somewhere read to rename the ROM update.zip
Did this and tried again.... No Joy!!!
Selected Fix permissions in an attempt to clean up and thats as far as I have got...
I'm at the end of my tether and dont know what to do...
Please, please, please someone help me get to the bottom of my dilemma..
Thanks for reading and any help in advance.
Just a little more info to help diagnose
CWM RM Details
Rom Manager Premium v4.8.1.3
Current Recovery: ClockworkMod 5.0.2.0
Latest Recover;ClockworkMod 5.0.2.0
Thanks again peoples for taking the time to at least read this..

No where in there did I see "I unlocked my bootloader"
That's fine that you're rooted, but to use CWM Recovery, install ROMs, make Nandroid Backups, etc. you need to unlock your bootloader first! See the international part of the Pudding thread (since your in UK) in the dev section.
Sent from my CM7 Atrix 4G

Ah Hah! You are correct at no point did I unlock my Booty, Thank you I shall give that a go and report back...

Ok so, I have trawled the forum and many others this avo on my research quest to unlock the bootloader as advised above but have been unsucessful so far.
I used the Pudding thread as you said.
when downloading the files advised I noticed that some were downloading as unrecognised files. I still proceeded to follow instructions as written.
Some of them like the RSD Lite I managed to unzip and extract with a programme I have however the next one needed said it was Undefined File type.
Anyway I deleted those files and tried following the other method listed underneath the driver via the link at "Guide for beginners provided by..."
This was unsucessfull as the "fastboot oem unlock" command was not recognised.
Pulled the batt and rebooted into normal mode and I'm back at SQ1
Bit stuck if anyone has any ideas..

Ok, here goes...
1) Make sure you have the drivers installed on your computer. (Available in Pudding Thread)
2) Go to pudding thread, and grab the Unlock Only IHOP sbf file (assuming your not on AT&T).
http://forum.xda-developers.com/showthread.php?t=1136261
"Unlock:
Unlocker only SBFs - These small 1mb SBF files will get your phone ready to fasboot oem unlock. They are the files most people should use.
ATT ONLY - Unlocker for 1.8.3 and 4.5.91 ATT firmwares
Orange/Bell/Telestra/Latin America/International users ONLY - Download IHOP"
3) Download & install RSD Lite. (Available in Pudding Thread)
4) Put phone in RSD Protocol Mode.
a) Power off phone
b) Upon Powering ON, hold Power Button + Volume UP
5) Connect Phone to computer via USB
6) unzip the IHOP sbf file to root of your C:\, open RSD Lite program, and drag sbf file onto File Name Box. Make sure RSD Lite sees your device connected to it, and then flash away.
7) After the sbf has flashed (hopefully without any errors), reboot your phone into fastboot mode (Power Button + Volume Down; when you see fastboot, press volume up to enter fastboot mode).
8) Re-connect phone to computer if you disconnected it.
9) In the folder where your fastboot files are located (if you don't have fastboot files, go download them from sticky in General Section), press Shift + Right Click, select Open Command Window Here.
10) With phone in fastboot mode, connected to PC and command window open in fastboot file location, type:
fastboot oem unlock
*This will give you your device #
Then type:
fastboot oem unlock [insert your # here]
10) Bootloader should unlock, then type fastboot reboot to reboot the phone. Should say Unlocked on boot screen now, if all went well.
11) Install Rom Racer's Recovery or Rom Manager, and you're good to go.
Think that about cover it... if you have any problems, give details of what is happening and at what step. Also, check the Pudding thread for possible solutions, as most problems have already been solved there.

Thank you for your explanation... I will give it a go when I get back from work tomorrow...
I appreciate you taking the time to help..

A BIG THANKS!!!
Thanks so much for the advice and instructions... Unlocked beautifully... Now to find the ideal ROM....
Dont suppose there are any suggestions for International (UK) Atrix users??
Really appriciate the help..

I would recommend that you flashed TWRP 2.0 through CWM direct link. It lets you have touch screen in recovery; much easier! Then if you like CM7 you could try this or if you like the MIUI style (like me!) you would want to try this! It hasn't in-game audio yet but it's much cooler in my opinion. But Neutrino CM7 is really great!

Im not sure, maybe someone else can confirm. You should be using moto-fastboot to unlock & not regular fastboot, right?

People have had problems with TWRP.............stick with Romracers CWM, it's tried and trusted. If the touch screen in CWM gets you off, so be it, but I'd rather have a recovery that works with all ROM's, and not just some.

[q] problems with lg gt540

hi guys.. could you help me with my problem.!
I have an LG GT540 android 1.6 firmware version(stock)
So here are my problems:
1. I tried to upgrade it from 1.6 to 2.1 using this tutorial http://forum.xda-developers.com/show...27&postcount=3 thanks to lavero.burgos for posting it, I was successful at first part, but I cant follow the next because my device wont go to fast boot,, I tried putting it off, then camera+poweron but it doesnt do anything. It doesn't light, no lg logo appears, just nothing although the computer can read the drive when I connect it through usb. So I cannot flash it to 2.3,2.3 because it just wont go to fastboot.
2. When I turn it on normally, It takes long before it response like after 30sec to light, but just light, no lg logo appears although it wasnt bricked because I can use it normally after just waiting to on.(annoying)
3. Since I upgraded it to 2.1, I lost all 3rd party application and the internal apps were the only left, so I copied all my saved apps (.apk) to my sd card but the problem is there is no saved app on my phone to read and install those apps from my sd card.(irritating)
4. My device wont read my sim card, when I start it it says "sim card unprovisioned" so basically I cant connect to mobile networks here in the philippines(im using globe telecom). I feel that Im stucked in the middle of nowhere since I cannot contact and txt all my family and friends.
5. I cant connect to wifi,, when my device detects wi-fi, I try to connect to it but from the log it only try to connect but doesn't obtain the ip address. Even when the wi-fi signal is strong, it does the same thing.
So please help me guys,,I want to hear from my fellow xda-developers badly,,,
PS. also those who have problems with their LG GT540 pls feel free to post and share it with us here... thank you all guys in advance....

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: protocol fault <no status>
C:\Desktop\fastboot flash recovery recovery.img

Did I miss something???

ok try again this time with the phone turned on. and then run the script and did you install the drivers?

yeah I installed the drivers...

hmmm maybe there are no fastboot drivers(main suspect....) there are a few ways to get it but for mine i just plug my phone in to my pc (windows 7 64bit) it just recognize it and tries to get the "google fastboot interface" drivers from windows update...

Try Volume Up+Search Key+Power to go into Fast boot Mode, There's different keys to activate Fastboot Mode (There is different versions of Fastboot)

Your phone is/was bricked
Hey, I'm sorry to bing back such an old thread, but I just wanted to say this for posterity: your phone has/had a soft-brick. This means: you can't see Android nor LG boot logos, can't enter Recovery and (maybe) can't access Fastboot, but I'm not too sure on that last one. Besides that, the phone works "okay", but you should try to fix it.
Basically this soft-brick is almost always caught when upgrading from 1.6 to 2.1, so everyone should have it, including me. It took me a whole year to realize how to friggin' fix it lol, but here goes what I did:
Thanks for your help everyone, I came to a solution after a full year lol. Here's my enlightenment, from another Thread:
------------------------------------------------------------------------------------------
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.

Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).

THANK YOU XDA!

[Unlock Bootloader,Install TWRP,Root Guide] H815EU-ONLY

edit : As of today - 28th June, this method ONLY works on the H815 EU models
update 26th July : Please go check the dream team's ROOT thread located here : [ROOT] TMO/VZW/ATT/SPRINT/INTL Root your LG G4 with Low Effort Root!
Thanks @thecubed , @autoprime , @IllegalArgument & @jcase for their hard work
Hi guys, a quick step by step guide to how I was able to unlock, install TWRP and Root my H815. Please don't hold me responsible if any issues arise with your phone. If you do this, you take your own responsibilities.
I tend to download all the tools in a single folder so it is easier to manage.
The LG Site:
1. go to this LINK and register.
2. you will get a confirmation email.
3. go to this LINK to unlock your bootloader (you will find the information on how to get your IMEI and Device ID lower in the post)
Your PC :
1. Be sure to have the LG drivers (i connected my phone first, it automatically installed the drivers on the computer.
update 27th July : thanks @the_scotsman in case you have driver issues please download these provided by @autoprime : LGUnitedMobile_Win_Driver_Ver_3.14.1
2. Be sure you have installed the ADB stuff that can be found here : Minimal ADB & Fastboot & ADB Installer (type Y to all the questions asked)
Install Minimal ADB first. Then type Y to all the questions the ADB installer asks. Close both windows once done.
Download TWRP 2.8.7. for H815:
1. go to this LINK and download it. Add it to your folder
Download SuperSu 2.46:
1. Download SuperSu 2.46 HERE (thanks @Chainfire ) and add it to your folder
PC & G4 love :
Once you are sure you have completed all the above tasks start rolling :
A. Enter your IMEI on the LG page
- you can find your IMEI on the G4 by going to settings > about phone > status
B. Get your Device ID:
1. hook up your LG on your PC (be sure not to be locked on your lockscreen, That USB debugging is checked and OEM checked in the Developer Options)
2. launch your CMD and type:
Code:
adb reboot bootloader
your phone will reboot
3. type this to get your Device ID
Code:
fastboot oem device-id
4. You will see two lines of number. Copy them and paste them together (to make one line) in the the Device ID fields on the LG site.
5 type :
Code:
fastboot reboot
5. close CMD
5. click Confirm on the site and you will receive by email a file called : unlock.bin.
Unlocking your bootloader:
1. once you get your LG email, save the unlock.bin in your folder
2. launch CMD from the folder (hold shift, right click the folder)
3. in CMD type :
Code:
adb reboot bootloader
4. once your phone is rebooted in bootloader type :
Code:
fastboot flash unlock unlock.bin
5. then reboot your phone by typing :
Code:
fastboot reboot
Normally your phone now has it's bootloader unlocked. When it boots you should see a message on the top left of the screen saying that.
COPY SuperSu and the downloaded TWRP file onto your phone (i put it in the download folder in the phone, not the SD) so you are ready for the next steps
Booting TWRP via ADB and bootloader mode
I personally think this was the easiest way to be able to root and clean install TWRP. Be sure your TWRP is in the folder.
1. Launch CMD from the folder (hold shift, right click the folder)
2. type (again) :
Code:
adb reboot bootloader
3. once your phone reboots and is in bootloader mode type :
Code:
fastboot boot TWRP2861.img
the new name of the file
or
Code:
fastboot boot p1.img
if you didn't rename it.
4. now you will reboot into TWRP.
Installing SuperSu
1. once you are in TWRP click install and go find your SuperSu file.
2. Swipe to install.
3. Once installation is done, reboot to system.
Once you have rebooted into the OS you will find the SuperSu app. Download the TWRP manager just to have it handy. And now i would install the TWRP file you have copied on your phone with flashify. I think it's a great tool.
2 ways to do it:
1. locate the file, click on it and choose to open with flashify then choose recovery and follow the steps
2. find the file via flashify and install.
(Don't download TWRP for H815 in the TWRP manager or Flashify as they are not fixed by @wolfgart (correct me if I am wrong))
once all this done and rebooted. Your phone will have TWRP and would be Rooted. Choose the TWRP manager to boot into recovery when you want.
I preferred to reboot the phone every time just to be sure...
If you have any comments, or i wrote something wrong, don't hesitate to correct me.
Have fun
UPDATE : Thanks to @autoprime you can also update your H815 EU to the latest Stock ROM : 10C (don't forget to thank him, as those guys are working hard to make your life easier!)
@the_scotsman, maybe you can pin this to help the lost souls until a one app does it all appears?

Well that was quick.

I have seen threads discussing about it yes, but haven't seen a clear guide on "how to" do it. Please enlighten me and i will ask this thread to be deleted. I don't like multi threads on the same subject, so i would be the first to ask that this thread be deleted.

I'm stuck on "fastboot oem device-id" command in cmd. Everything up to that point goes smoothly.
command line says "waiting for device" and the phone screen doesn't show phone ID, but gives me options 1-3. 1 being to show device ID, can't remember what the other ones are now. But I can't select "1". What am I doing wrong?
I have USB debugging on, also the OEM unlock is checked in development options.

unplug your device, if you can't restart it, by keeping your finger pressed for 10 seconds on the power button, take battery out.
Once you put the battery back in, restart the phone, plug in the phone in the computer, restart the CMD, and start the procedure again. :
2. launch your CMD and type:
Code:
adb reboot bootloader
your phone will reboot
3. type this to get your Device ID
Code:
fastboot oem device-id

I've tried this a few times now, same outcome, same thing, don't get a code, only get the 3 options and the power off 10 second thing, which doesn't work btw, have to pull battery every time

The numbers should show on your CMD window on your computer not the phone.
If the CMD window only shows "waiting for device", did you try to shut the CMD windows?

ah, thought they were supposed to show on the phone screen.
not sure what you mean by shutting the cmd window? I just get stuck on that "waiting for device" message in cmd, at which point I unplugged the phone, did a battery pull and tried again. I've tried about 5 times now, I double checked everything, have all the drivers installed etc.
Oh, and I do have the h815 EU version of the G4. I'll keep digging.

Could someone try out netflix, camera, divx files, YouTube and all the things that people were afraid of loosing. I for myself would really like to root but I dont want to loose any functions by doing that.

I have no issues with Netflix, divx, camera or YouTube.

Just a reminder that this does not work with all H815's as of 6/5/15. I think those of us that got a non EU region specific H815's get stuck when requesting a bootloader unlock from LG. Most of us are getting "not found suffix" when trying to submit the IMEI# and device ID. Note: trying different internet browsers does nothing, so don't bother.
We'll have to wait for LG to either approve all region G4's or another method. Cheers for making a guide though.

Got the same Problem and fixed it, because, that are restriction/Firewall/Domaincontroler/Groupright Problems on ur PC.
Here the link, were i short explain my problem. http://forum.xda-developers.com/g4/general/howto-unlock-twrp-root-1-thread-t3130538
And now i see there is a HOWTO Thread
SO i have doubled it :crying:
But same answers like here "we got like 5 Threads", but like u said @SAO NOT 1Thread were all-in-one is explained! :good:

Is there a reason why we have to temporarily boot into TWRP to install root and then install TWRP via a secondary method?
Like, why can't we just do a "fastboot flash recovery twrp.img" command to install TWRP like most other devices with an unlocked bootloader?

Does this method break DRM?

The T-Mobile LG K7 Thread

Firstly, I'd like to start by saying that I am making this post because there is little information on the T-Mobile LG K7(K330) and what little information is found is scattered throughout the site.
The LG K7 is a budget phone and you do get the biggest bang for your buck if money is tight. Right now, you can get the Walmart version (for $50!) and flash it to T-Mobile which I will explain in the steps below.
I HAVE ONLY TESTED THIS ON THE WALMART FAMILY MOBILE VERSION OG THE LG K7, THIS PROBABLY WON'T WORK WITH OTHER DEVICES
This is a really great phone and awesome phone to start developing on if one chooses to do so. That being said, let's go ahead and flash the phone to T-Mobile if you haven't already. Most of this information came from Billybobjoe13245's Beautiful Post
Disclaimer: I tested this on Android Lollipop version 5.1.1 and that's what worked. Feel free to try whatever you feel but in any case, I am not responsible for what YOU do to YOUR device, if YOU mess up, YOU will have to deal with the consequnces. Now that that's out of the way,
You're going to need:
Windows Computer with Administative Priviledges (because LG binaries)
An LG K7 (K330)
A USB Cable
About 20 minutes
Once you have all those ready, start downloading the necessary files:
LG UP Software (You're looking for Lab Version 1.10) OFFICIAL | MIRROR
LG Mobile Driver Software(I used ver. 4.0.4.0 but the latest might work) TESTED VERSION | LATEST OFFICIAL
The "WEB_K33010h_00.kdz" file from Billybobjoe13245's Mega Repo
And now it begins.
Install the Mobile Driver Software
Install the LG UP Software
Turn you LG K7 off
Turn on your K7 while holding the DOWN button to boot into Download Mode
Open the LG UP Software
Select "Upgrade" in the separator between the two lists
Hover over "BIN FILE" under "FILE TYPE" and you should see three dots (...) to select a file
Here you select where you've downloaded the WEB file
Click start and let it do it's thing
Once it is finished it will reboot your device and tell you that it has been completed. You should now be able to use a T-Mobile nano-SIM card with absolutely no issues.
Next you Probably want to
ROOT YOUR DEVICE
THIS WILL COMPLETELY WIPE YOUR PHONE SO BACK UP WHATEVER YOU NEED TO
You'll need an internet connection for this to work properly . Let's go:
Make sure your phone has enough charge (%75+)
Go to Settings > General > About Phone > Software Info
Click Build Number 7 times or until it says "You are now a developer"
Go back to General Settings
Go to "Developer Options"
Enable "OEM Unlock"
Enable "USB Debugging"
Next youl'll want to make sure that you have the Android Debug Bridge (ADB) installed. If you don't have it , these guys have your back. Make certain that it is correctly installed and that you can access it using your command line.
Download this Team Win Recovery Project image on your PC (it's from my mirror)
Make sure it 's in the folder that ADB is in or that ADB can recognize
Plug in your phone into your computer if it's not already
You'll want to boot into the bootloader using adb so type:
Code:
adb reboot bootloader
Wait for it to reboot into the bootloader (shouldn't take long)
MAKE SURE THAT IT SAYS "BOATLOADER UNLOCKED" ON THE TOP LEFT, IF NOT
Type the follow to confirm that it sees your device:
Code:
fastboot devices
If you see you're device, all is good. Now we have to unlock the bootloader with:
Code:
fastboot oem unlock
If it reboots, use adb to go back to the bootloader
Time to flash the recovery with:
Code:
fastboot flash recovery twrp-image-3.img
Finally:
Code:
fastboot reboot
You now have the TWRP recovery on your phone but YOU'RE NOT DONE AS YOU DONT HAVE ROOT PERMISSIONS and your phone should have been wiped clean so you might have to reinput your details.
To finish getting root access:
Make sure youer phone is still plugged in
Download ChainFire's SuperSu on your computer
Move SuperSu from wherever you downloade it to your device
Reboot your phone into recovery by turning it off and turning it back on while HOLDING the UP button.
You should see the TWRP recovery screen.
Click install and choose the SuperSU zip file that you downloaded from ChainFire's site
If you want, you can select "Reboot after Installation" if you wish.
Swipe the slider all the way to right to start the install
Reboot
You should now have SuperSu on your device , allowing you root access
That's all you need if all you wanted is to root, but you're probably going to want BusyBox, Xposed Framework and an Equalizer if you're like me because by default the sound is terrible and Equalizers like Viper4Android makes it a whole lot better and works with Spotify! Let's get started:
How to get BusyBox
It's actually pretty simple.
Go to Play Store
Search "BusyBox"
Download "BusyBox" or "BusyBox Pro" by Stephen(Stericson)
Install it
Open it
Select the directory where you would like it installed, I installed in both "/system/xbin" and "system/bin" for everything to work how I wanted
It will ask you to grant it Root Permissions, select "GRANT"
Wait for it to install
You now have BusyBox!
If you don't know what BusyBox is, to put it shortly , it's a set of command line tools for Unix and Unix-like systems, like Android, to make things a bit more developer friendly. You can read more at he BusyBox official site.
Next I'll show you how to get the
Xposed Framework
Most of this information came from this post so if you need more information, read that post.
Go to Settings > General and select "Security" under the "Privacy" Category.
Scroll down to the "Phone Administration" category and make sure "Unknown Sources" is checked.
Download The Xposed 3.1 apk installer on your phone
Install it
The actual framework won't work because you have to install it in your recovery so then,
Download the LG K7 Xposed Framework image and put it on your phone's internal storage
Reboot into recovery and Install the Xposed Framework image you just put on your device.
Once it is installed, you can reboot and it should be working in the app.
Lastly, if you want better sound, you'll want
ViPER4ANDROiD
Most (if not all) of this information came from this post.
Go to Settings > General > Developer Options
Scroll down to the "Media Category" and select "Use AwesomePlayer (deprecated)" as Viper won't work with NuPlayer
Download SELinux Mode Changer OFFICIAL | MIRROR
Install it
Open it and grant it Root Permissions
Select Permissive Mode
Download this version of ViPER4ANDROiD | MIRRIR
Reboot into Recovery and Install the ViPER4ANDROiD zip file
Once it's done, you can reboot
Open the ViPER4ANDROiD app
It will ask you to install/update the driver
It should continue with no problems and you should have better sound
And you're done! That's everything I know thus far. There are no custom ROMs yet but I want to attempt on working on one(although I've never developed or ported a ROM before) as soon as I get all the information on how to do so . Be sure to thank the Original Posters/Developers and donate to them if you have the means as they put a lot of time and effort into bringing you the best experience possible.
PLEASE PLEASE PLEASE let me know if I forgot something or if there is a type and I will fix it right away!

i have a K7 from metropcs, but sim unlocked working absolutely perfectly on tmobile. all i did was get metropcs to unlock my sim, and i was only with them for nearly 2 weeks, not 90 days. anyways, we have a twrp for the lg k7 thread here on xda too, with lots of other modding talk going on in it http://forum.xda-developers.com/general/general/qa-metro-pcs-lg-k7-lgms330-t3331678 btw, there is no such thing as an official team win recovery project for the k7, it is ported to the k7.

Thank you for the reply. I remember seeing this post but wasn't sure if it worked for the K330, I had only put things in this thread that I tested but I will try the image pointed out in your post and add it. I will also edit out the "official twrp" statement. Thanks again for the feedback.

Nice writeup OP.
Unfortunately, I picked up the TMobile branded K7, unlocked the bootloader, then attempted to flash twrp -- I can never boot into TWRP (I get the red exclamation warning).
Is there any hope for me?
If I return it and and then pick up the walmart one will it support my Tmobile 4G/LTE?
Thanks.

Thanks, I'll attempt to add more details. I purchased this phone (walmart.com/ip/T-Mobile-LG-K7-TD-Prepaid-Smartphone/51671353).
Model #: LG-K330
Software version: K33010h
1. Used windows (via virtualization) to update to WEB_K33010h_00.kdz and it worked.
1a. enable dev settings, usb debug, oem unlock.
2. Downloaded adb bridge for Mac which comes with adb and fastboot commandline tools
3. plug in phone and ran 'adb reboot bootlader' to enter bootloader in order to use fastboot to unlock
4. run 'fastboot oem unlock', rebooted and use 'adb reboot bootloader' to flash twrp -- I now see bootloader unlocked in upper left
5. run '.fastboot flash recovery twrp-image-3.img' and 'fastboot reboot'
6, at this point I just shut off my phone and attempt to enter recovery with "Reboot your phone into recovery by turning it off and turning it back on while HOLDING the UP button."

Thanks, I'll attempt to add more details. I purchased this phone (walmart.com/ip/T-Mobile-LG-K7-TD-Prepaid-Smartphone/51671353).
Model #: LG-K330
Software version: K33010h
1. Used windows (via virtualization) to update to WEB_K33010h_00.kdz and it worked.
1a. enable dev settings, usb debug, oem unlock.
2. Downloaded adb bridge for Mac which comes with adb and fastboot commandline tools
3. plug in phone and ran 'adb reboot bootlader' to enter bootloader in order to use fastboot to unlock
4. run 'fastboot oem unlock', rebooted and use 'adb reboot bootloader' to flash twrp -- I now see bootloader unlocked in upper left
5. run '.fastboot flash recovery twrp-image-3.img' and 'fastboot reboot'
6, at this point I just shut off my phone and attempt to enter recovery with "Reboot your phone into recovery by turning it off and turning it back on while HOLDING the UP button."
It is at that point I see the android icon with a red exclamation. I have to pull out my battery to reboot the phone.

Before step 5, try copying this into the cmd prompt:
Code:
fastboot boot twrp-image-3.img
and then allow it to make modifications to your system. Then go to reboot > bootloader and then let it install supersu, then flash the TWRP image in step 5. This fixed the red triangle problem for me. Also, once you are back in android, tap the notification for SuperSU and tap TWRP to let it finish the process.
Hey, @Bughora I can't seem to boot to recovery via the key combo you describe. I hold Vol-UP and then press and hold power while still holding Vol-UP and also tried without holding power, but it doesn't take me to TWRP. If I hold both Power+Vol-UP, oddly it will start optimizing apps again but if I don't continue to hold Power, it just boots normally... am I misinterpreting what you mean in the OP?
EDIT: Other methods of getting to recovery like "adb reboot recovery" work flawlessly.

You're welcome. Also, try this version of TWRP which will let you boot into TWRP with the hardware keys described in the OP. Here is a snippet of the OP explaining how:
Twrp with button combo.
With device off press and hold power and volume down until LG logo pops up quickly release the power and press power quickly until the factory reset dialog pops up press volume down to yes press power to select than it will show the same dialog with yes already selected use power to select and you will be taken to Twrp recovery.

I know it says factory reset, but it will take you to TWRP. If you are hesitant (like I was initially), boot to recovery with ADB first, make a backup, and then try it. Good luck, and happy modding!

TWRP for T-Mobile & Metro PCS
In case you missed it, czarsuperstar created Twrp for the K7 (Metro/T - Mobile)
(XDA link)
~~~~~~~
update:
Doh! I just saw that the TWRP link is posted just above this post. :silly:

Okay so I'm very new to all this so I apologize ahead of time if my issue is super simple but I don't know what to do. I've been following the steps word for word (had a couple minor hiccups) and I'm at the point where I need to install supersu. I moved the zip file to my internal storage, then when I attempt to restart the phone in recovery mode it automatically goes into download mode followed by freezing at software update, instead of letting me choose to install supersu as the steps state. Can someone help me figure this out please?
EDIT: Well it took me a while but I figured out my issue. From what I understand, the twrp was successfully flashed on my phone but when rebooting the manufacturer kernal was wiping that recovery and replacing with the stock recovery. Instead of rebooting with adb I manually turned off my phone then booted up my phone into the recovery and the twrp menu came up!

Firstly, I'd like to start by saying that I am making this post because there is little information on the T-Mobile LG K7(K330) and what little information is found is scattered throughout the site.
The LG K7 is a budget phone and you do get the biggest bang for your buck if money is tight. Right now, you can get the Walmart version (for $50!) and flash it to T-Mobile which I will explain in the steps below.
I HAVE ONLY TESTED THIS ON THE WALMART FAMILY MOBILE VERSION OG THE LG K7, THIS PROBABLY WON'T WORK WITH OTHER DEVICES
This is a really great phone and awesome phone to start developing on if one chooses to do so. That being said, let's go ahead and flash the phone to T-Mobile if you haven't already. Most of this information came from Billybobjoe13245's Beautiful Post
Disclaimer: I tested this on Android Lollipop version 5.1.1 and that's what worked. Feel free to try whatever you feel but in any case, I am not responsible for what YOU do to YOUR device, if YOU mess up, YOU will have to deal with the consequnces. Now that that's out of the way,
You're going to need:
Windows Computer with Administative Priviledges (because LG binaries)
An LG K7 (K330)
A USB Cable
About 20 minutes
Once you have all those ready, start downloading the necessary files:
LG UP Software (You're looking for Lab Version 1.10) OFFICIAL | MIRROR
LG Mobile Driver Software(I used ver. 4.0.4.0 but the latest might work) TESTED VERSION | LATEST OFFICIAL
The "WEB_K33010h_00.kdz" file from Billybobjoe13245's Mega Repo
And now it begins.
Install the Mobile Driver Software
Install the LG UP Software
Turn you LG K7 off
Turn on your K7 while holding the DOWN button to boot into Download Mode
Open the LG UP Software
Select "Upgrade" in the separator between the two lists
Hover over "BIN FILE" under "FILE TYPE" and you should see three dots (...) to select a file
Here you select where you've downloaded the WEB file
Click start and let it do it's thing
Once it is finished it will reboot your device and tell you that it has been completed. You should now be able to use a T-Mobile nano-SIM card with absolutely no issues.
Next you Probably want to
ROOT YOUR DEVICE
THIS WILL COMPLETELY WIPE YOUR PHONE SO BACK UP WHATEVER YOU NEED TO
You'll need an internet connection for this to work properly . Let's go:
Make sure your phone has enough charge (%75+)
Go to Settings > General > About Phone > Software Info
Click Build Number 7 times or until it says "You are now a developer"
Go back to General Settings
Go to "Developer Options"
Enable "OEM Unlock"
Enable "USB Debugging"
Next youl'll want to make sure that you have the Android Debug Bridge (ADB) installed. If you don't have it , these guys have your back. Make certain that it is correctly installed and that you can access it using your command line.
Download this Team Win Recovery Project image on your PC (it's from my mirror)
Make sure it 's in the folder that ADB is in or that ADB can recognize
Plug in your phone into your computer if it's not already
You'll want to boot into the bootloader using adb so type:
Wait for it to reboot into the bootloader (shouldn't take long)
MAKE SURE THAT IT SAYS "BOATLOADER UNLOCKED" ON THE TOP LEFT, IF NOT
Type the follow to confirm that it sees your device:
If you see you're device, all is good. Now we have to unlock the bootloader with:
If it reboots, use adb to go back to the bootloader
Time to flash the recovery with:
Finally:
You now have the TWRP recovery on your phone but YOU'RE NOT DONE AS YOU DONT HAVE ROOT PERMISSIONS and your phone should have been wiped clean so you might have to reinput your details.
To finish getting root access:
Make sure youer phone is still plugged in
Download ChainFire's SuperSu on your computer
Move SuperSu from wherever you downloade it to your device
Reboot your phone into recovery by turning it off and turning it back on while HOLDING the UP button.
You should see the TWRP recovery screen.
Click install and choose the SuperSU zip file that you downloaded from ChainFire's site
If you want, you can select "Reboot after Installation" if you wish.
Swipe the slider all the way to right to start the install
Reboot
You should now have SuperSu on your device , allowing you root access
That's all you need if all you wanted is to root, but you're probably going to want BusyBox, Xposed Framework and an Equalizer if you're like me because by default the sound is terrible and Equalizers like Viper4Android makes it a whole lot better and works with Spotify! Let's get started:
How to get BusyBox
It's actually pretty simple.
Go to Play Store
Search "BusyBox"
Download "BusyBox" or "BusyBox Pro" by Stephen(Stericson)
Install it
Open it
Select the directory where you would like it installed, I installed in both "/system/xbin" and "system/bin" for everything to work how I wanted
It will ask you to grant it Root Permissions, select "GRANT"
Wait for it to install
You now have BusyBox!
If you don't know what BusyBox is, to put it shortly , it's a set of command line tools for Unix and Unix-like systems, like Android, to make things a bit more developer friendly. You can read more at he BusyBox official site.
Next I'll show you how to get the
Xposed Framework
Most of this information came from this post so if you need more information, read that post.
Go to Settings > General and select "Security" under the "Privacy" Category.
Scroll down to the "Phone Administration" category and make sure "Unknown Sources" is checked.
Download The Xposed 3.1 apk installer on your phone
Install it
The actual framework won't work because you have to install it in your recovery so then,
Download the LG K7 Xposed Framework image and put it on your phone's internal storage
Reboot into recovery and Install the Xposed Framework image you just put on your device.
Once it is installed, you can reboot and it should be working in the app.
Lastly, if you want better sound, you'll want
ViPER4ANDROiD
Most (if not all) of this information came from this post.
Go to Settings > General > Developer Options
Scroll down to the "Media Category" and select "Use AwesomePlayer (deprecated)" as Viper won't work with NuPlayer
Download SELinux Mode Changer OFFICIAL | MIRROR
Install it
Open it and grant it Root Permissions
Select Permissive Mode
Download this version of ViPER4ANDROiD | MIRRIR
Reboot into Recovery and Install the ViPER4ANDROiD zip file
Once it's done, you can reboot
Open the ViPER4ANDROiD app
It will ask you to install/update the driver
It should continue with no problems and you should have better sound
And you're done! That's everything I know thus far. There are no custom ROMs yet but I want to attempt on working on one(although I've never developed or ported a ROM before) as soon as I get all the information on how to do so . Be sure to thank the Original Posters/Developers and donate to them if you have the means as they put a lot of time and effort into bringing you the best experience possible.
PLEASE PLEASE PLEASE let me know if I forgot something or if there is a type and I will fix it right away!

Try installing this official version of TWRP with the TWRP app. Or using this command in terminal
Code:
dd if='/path/to/TWRP/image' of='/dev/block/bootdevice/by-name/recovery'
Also, if that doesn't work. It's most likely because you didn't unlock the bootloader. Go to "Step Nine: Unlocking The Bootloader" on this thread http://forum.xda-developers.com/general/general/ref-metro-pcs-lg-k7-lgms330-t3362555
