[Q] LG G2 bricked, with disabled usb debugging ( PLEASE HELP!) - G2 Q&A, Help & Troubleshooting

I rooted my lg g2 D802, put cwm recovery and flashed cyanogenmod 11. It worked perfectly for 80 hours, when my battery died. I tried to recharge it but my phone won't boot anymore, I only see lg logo. I can't get into recovery, but i can get into download mode. I tried flashing stock ROM through PC but it doesn't work. PC recognizes phone in ports but when I start Flashtool it just says "Waiting for Connection". After reading tons of threads about bricked phones, it seems that phone has to have USB debugging enabled. When i flashed cyanogenmod USB debugging was disabled. And now my phone is bricked with USB debugging disabled.
Please help me to restore my phone, I'm desperate now. I've been trying various methods for 3 days and nothing seems to work. What should I do?

I managed to recover my phone.

Please tell how, I'm trying to unbrick my phone for hours..

If you have lg logo use lg support tool. I had the same problem and it restores my phone to factory firmware. Dont get scared if you see a lot of ?????????? On lg suppor tool. Just look for the options.....check where the options are before connecting phone because when plugged letters change to ??????. Works 100% for me.

To be completely honest, I'm not sure how exactly did I manage to unbrick it. I tried to dig something with adb and fastboot. I don't know what exactly did I do but I didn't get any visible result. In my desperation I tried to enter recovery (power + down) once again (after at least 10 attempts during these 3 days) and it somehow worked. Then I flashed ROM that was already in my memory. It seems that my problem was consequence of OTA update.
I'm new with android so I'm still noob. I'm sorry that I can't help more.

i have a same problem if u solve it

Did you try doing an upgrade recovery using LG Mobile Support Tool on Windows 7 machine?

[Q] [L7][P700][Bricked] Hard bricked Optimus L7 P700

Hey guys,
Yesterday I tried unlocking my phone using the tools provided on this forum, but somehow my device got hard bricked.
It is just laying there with a black screen. It won't turn on, won't boot into recovery or emergency mode. Nothing.
But when I connected it to my PC (running Windows 7), I did hear the sound that it recognised it as a device, it just couldn't find any drivers for it, so I wen't to look into that.
Landed on the debricking method using QPTS on the CyanogenMod forums and I managed to find drivers for Windows 7, so no need for an XP computer!
There were some other Optimus L-series brickers who gave up on the process, but I have still some hope left.
Did all the work that had to be done, decompiled V20D KDZ for our device, converted the first 512 bytes of the partition.bin to .mbn, installed QPTS, and so forth.
Hooked up my phone to the pc holding the volume-down button, and QPTS actually recognised it as a phone in downloading mode!
Then that's where I got stuck. Using the HEX files from this thread, I get the following error:
Code:
Status: Software Download Aborted
Errors: Could not determine the HEX file's scrambling method. The file is invalid.
Do any of you have a clue on how get things working again?
The QPTS tool only lists MSM7x30 (eMMC) as ARMPRG to use for the phone in dowload mode, not the MSM7x27a we are using. Might this be part of the problem?
Any help is highly appreciated!
Can you go to emergency or download mode?
Battery taken out, hold the vol up + connect to usb, connected to the pc. Then you will see in a green screen with emergency mode.
Once your done that, be sure you installed the LG drivers, flashed through kdz.
You can use homero's v20 stock, it's already had cwm and unlock bootloader and v20 baseband.

Nope, can't get into emergency mode, screen stays black, no matter what. So yeah, just flashing a new KDZ isn't an option. :crying:

Does the kdz flasher recognized the phone? If it's turn on and connected to the PC.

You should try launching emergency mode some more. Install lg drivers. Take out battery, hold Vol up button and plug in usb. Make sure port works.
Thanks for the replies, guys!

I can't turn the device on. When I connect it to the PC, Windows sees the phone as an 'Unknown Device', even with the latest LG drivers installed.
And by KDZ flasher you mean the BC2App, right?

Tried it a dozen times, with different combinations too. Only thing that happens is the sound windows makes when a device is plugged in.
Any chance a method like this would work? If the .img.zx file would be edited for our device ofcourse.
Hey all,
I couldn't get any further debricking my phone myself, so I just brought it to a repair shop. I'm hoping they can do something using JTAG or something.
Regardless of getting my phone working again (hopefully), I would still love to see if we can find a way to debrick hard bricked devices. If we can find a solution, I'll volunteer for writing a tutorial

D802 How to unbrick?

Hi, I've got a HUGE problem.
Today I decided to root my G2 d802 (european free distribution) and flash a CM rom.
After cleaning dalvik and factory reset i tried to flash this rom but Status 7 showed up.
So, I tried to launch G2 and find a solution for it but it started to boot loop.
Okay.
Even worse, (don't ask how, but it wasn't me!) there PROBABLY was format /system,,
After that my G2 stucks on LG logo and nothing else happens. No loop no anything. I can only go into recovery while seeing white screen asking if I agree to do format. Everytime, but it never boots normally, it's always stuck.
So, what can I do?
I can't access the phone from my computer while beeing in the recovery (it appears as a device, but i cannot access it..).
I can only use recovery
LG G2 D802
CWM-based Recovery v6.0.4.4
Sorry for bad english, not my native language.
Help me, please! How can I unbrick my G2?!
So I tried to flash Stock rom, but when in download mode G2 isn't considered as plugged into a computer. LG Mobile Support Tool can't find the device... Any help?

There is a way to probably fix it but if you cant just put your phone in the water till it breaks and use your warranty to get another one thats what I did with my D801 when it bricked

Nevermind. It came back to boot loop, so it's not bricked.
But i've got some problems.
Mainly - i still can't access my phone through my computer.
When i try to flash Stock Rom (http://forum.xda-developers.com/showthread.php?t=2432476 this thread) i recive: http://i.imgur.com/ijSgtwp.png - screenshot from Device Manager when in download mode: http://i.imgur.com/kMLCW7t.png and when in recovery: http://i.imgur.com/wGU6qnz.png
So we're back into boot loop.
Any help? Please?
Can you attach an otg card reader or flash memory stick from recovery?
adb sideload helps you. or adb push
The problem is, because of a tutorial on my local Android site which tells how to unloop boot in G2 I've got TWRP now instead of CWM (it was about access to terminal something and writing a command, but it didn't do ****, but it seemed to work for few people), and it would be fine, but... now computer doesn't recognize my phone. Unidentified Devices: LG G2-D802, so I can't access sideload...

I've got OTG Cable (bought for my Nexus 7) somewhere, but none of above.
LOL NEVERMIND
Becouse I had nothing to lose i decided to try to flash CM and it worked.
CWM couldn't flash it for 5 times, TWRP did it immediatly.
Topic closed, thank you for your responses.
You need to first download the kdz and lg flash utility with drivers.
Install drivers
The factory reset deleting system, cache, internal sd.
Then shutdown your g2.
Start to downloaded mode connecting your g2
Flash kdz & voila... Done
I too bricked my phone before. My flashing stuck at 49%. Recovered using above method, all is well now
This works 1000%. I bet on it. Just remember to wipe the phone completely before flashing. You will return to stock with unrooted status in download mode. U will have your warranty back too

Lg g2 stuck in boot loop, vzw i have tried everything need serious help!!!!!!!!!!!

Been running pac rom, tried installing a custom ROM that was almost stock kitkat for Verizon. Forgot to wipe i think, and now i have been screwed since. Stuck in boot loop. Factory reset can be reached, but screen goes black everytime and doesnt allow me to get into TWRP. Only thing accessiable is download mode. But device is not recongized in adb, only when its bootlooping. But it is recognized in devices and printers in bootloop. New computer also, no RSA authentication, while in bootloop ive tried to adb boot recovery commands, but no authorization. Im completly stuck and have been for days, ive read so many posts but everything i have found doesnt match all my problems. and most people dont read the entire post or problem before submitting a dumb answer, which is a duh i tried that kind of thing thanks for nothing. SO PLEASE HELP IF YOU CAN THINK OF ANYTHING ELSE. IM GOING CRAZY OVER HERE AND LOOSING MY MIND> WHO EVER CAN HELP ME, IS GOD AND SHOULD BE CONSIDERED TOP DOG GENIOUS>
When you get to the white Factory Reset screen, pressing the power button 3 or 4 times won't get you back into TWRP?
Well u press it once to give conform option, and the second time, turn it black

This would be easy if my laptop didnt get stolen that had authorization to do cmd commands. Anyways, really need some brain power put togeaher on this on and \fast. Is anyone down with maybe skyping with me, to visually see whats going on and troubleshoot it as if you were remoting into a computer.

everything you need is here.
check again if you don't have USB connection of any kind. If you do have something in the PC responding to the G2 being connected, it isn't a hard brick and you can fix it with this: http://forum.xda-developers.com/showthread.php?t=2582142
Otherwise you just have to do this short the caps thing. Be careful and renember that this is always a better option than staying with a bricked device. You can also try to give the phone to some experienced repaired and tell him about the method and how will it cost.

VERY IMPORTANT!!!!!!!
You must use the img files that correspond to the ROM you have installed before getting the problem to avoid breaking your phone. The link above is for 10b_EUR_16G firmware version. So don't use those files if your firmware version was not that one. Instead you should look for img files corresponding to the current version installed in your phone. If you don't know what version you've installed then don't use this method because you will break your phone.

You have to know which model your phone is.
Do you know your phone's IMEI? http://www.lgkdz.com/ Go here and it will get the file you need to download via your IMEI (even though it is risky to put the IMEI in the internet).
Otherwise you can just search for your kdz file by knowing what model you have and what stock rom you had last time. You can always revert to that.
Mine is D802 32GB, has V30b-EUR software. That is enough for me to get the correct kdz file even by searching in the links provided in the tutorials I mentioned in my last message

Do you have access to download mode? Since your PC recognizes the phone as MTP Device, I'm not sure but I think that's only possible if you have /system/ working since the other partitions don't have MTP support originally.
If you have that, go there: http://forum.xda-developers.com/showthread.php?t=2432476
Flash with the tot method and you should be good to go.
But wait for someone who can confirm what I'm saying since I'm no expert.

LG Stylo 2 Plus Bootloop

Model: LGMS5500, Lg Stylo 2 Plus (MetroPCS), Android Marshmallow 6.0.1
Here's my issue.
I recently rooted/installed TWRP for this phone, all was working well until one day the system started running extremely slow.
Pulling down the notification bar took about five seconds; it took about the same amount of time to turn the screen on/off.
I searched everywhere for fixes and tried every one to no avail, so I figured I'd do a factory reset.
After trying the factory reset from the settings app; all the phone did was reboot.
So I went into TWRP and reset/cleared data from there.
Now when the phone starts, it brings me to a screen saying "Encryption unsuccessful" and only gives me the option to reset my phone.
When I press this button, it just reboots to the same screen>
I can't get into TWRP because before all of this happened, I disabled USB debugging.
So I can't use my PC to get into recovery.
There's also no way to boot to recovery with just the hardware buttons; the only way to get to TWRP with this phone is either from apps on the phone itself or using ADB.
Am I S.O.L here? Am I going to need to buy a new phone? I'd rather not have to drop another $175 because of something this dumb.
Any help is greatly appreciated.
