Here are all the current KDZ & TOT files for flashing Your G4 Back to Stock! This Guide includes 3 different methods. KDZ, TOT, and LGUP (Which flashes both KDZ & TOT files)
Will Be adding Firmwares as I get them, This guide applies to general ALL LG models including G2 and G Pro, G Flex, G3, G4,G5, Etc. .
NOTICE! - IF you download fails or does not download all the way USE A DOWNLOAD MANAGER!, Files that are usually over 1GB browsers have issues downloading them especially if you have a slow connection.
First Off Not Responsible if you flash the wrong one!!!!
Please read HERE if you plan on downgrading, WARNING downgrading some models will result in a perm brick! Mostly AT&T, T-Mobile, and Sprint models.
The Files are Hosted on my server for fast speeds! Most if not all NEEDED KDZ & TOT files are on my Server

New KDZ Method for LG G4 with MM
This is the NEW KDZ Method for the LG G4!!! Thanks to @shakeyabooti !!
shakeyabooti said:
NEW software!!!!!...... LGUP WILL FLASH YOUR KDZ files
Download LGUP fromor here http://oceanhost.eu/eps4h4pmwphu/LGUP.zip.htm thank you hyelton for this link :good:
Install LGUP_8994_DLL_Ver_0_0_3_23 first and then LGUP_Install_Ver_1_14_3
Make sure you have downloaded the required KDZ file MM or LP
Start LGUP prog on your computer "make sure your phone is plugged in"
If you have a problem that LGUP does not see your LG G4, leave your mobile connected via USB and leave LGUP running, restart your mobile, hopefully this will solve the problem.
TO UPGRADE TO MM from LP - make sure BIN file is ticked and in the File Path point it towards the MM KDZ you have downloaded. MAKE SURE YOU HAVE CLICKED UPGRADE! This will update you from LP to MM with out wiping any of your info. Press Start. Make cup of tea and be patient
TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient
TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient
If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
YOU WILL LOSE ROOT!
There is no need to enter download mode! LGUP will do it for you.

Thank You schafi03
Some handy ADB and Fastboot comands because I've been asked so many times, make sure you have ADB and Fastboot installed ofc lol
I always put TWRP in the ADB folder - so if I want to boot into TWRP with out installing it this is what I do:
make sure you open a command prompt in the ADB folder "VERY IMPORTANT" and type:
adb reboot bootloader <enter>
fastboot boot TWRP.img <whatever your TWRP image is called in your ADB folder><enter> dont forget the .img at the end
That will re-start your phone straight into TWRP - copy files to and from your mobile, install root etc etc......
If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" then press install then select images then select recovery NOT BOOT then swipe to flash. This method does not install TWRP app on your phone, all you need is a reboot app from the play store that will re-boot you into recovery.
I hope I have covered most things that I have been asked, don't forget to search the thread for answers before asking, if you can't see something you are concerned about or are having trouble with a certain part don't be afraid to ask no matter how dumb you think it sounds, we all could do with some guidance at some time. Have fun everyone! :good:

FAQ:
KDZ Method - Network connection error is normal, Just move over that Window.
T-Mobile (H811) Version cannot be downgraded
Currently you cannot downgrade from Android 6.0

AT&T H810 TOT & back to stock info!
autoprime said:
Ok... alrighty... so.. AT&T H810 10O is "V2"
H810 10A was V0. then there was 10E and 10G which were V1.
I saw mention of a 10l but I have no idea about that at all. could be V1.. or could be V2. haven't seen the files for that. anyway.. doesn't matter. forget about 10l
H810PR KDZ's were all V1.
basically unless you are on 10A and holding out for a bootloader exploit on V0... this TOT is completely safe to use regardless of what current version you are on. For example, you could be on 10g (V1) and still flash this TOT safely.. it would just increase the qfuse from V1 to V2.
V2 is no more locked down than V1... so there's no worry about losing your current v1 and no need to stay on 10E or 10G. 10A V0 is the only version worth holding onto.
Of course "V3" may come with android M... but too early to say one way or another on that. if M is indeed V3.. then anyone that upgraded to M could no longer flash this TOT. Hopefully the USA carriers knock it off with increasing the qfuse versions tho and it stops at v2. I will edit the previous sentence after Android 6.0 M comes out for H810 to confirm.
H810PR info: If there is an AT&T user who previously flashed H810PR KDZ to unbrick.. they should be safe flashing this 10o TOT if they want to get back into AT&T land.. hopefully fixing their green camera issue. H810PR users who have an original H810PR (not a converted att h810) should NOT use this TOT as it will increase your qfuse from V1 to V2 and you'll be stuck with AT&T software... plus there's just no point in using it since H810PR has official KDZs.
so.. summary. 10o is v2. everyone on an AT&T H810 can flash this safely without fear of bricking.. as there is no higher qfuse version yet. AT&T H810 users who "converted" to H810PR can safely flash the TOT. Original H810PR users should avoid flashing this TOT as they'll get stuck on V2 AT&T software. The only other users who should maybe try not using it are those on 10A V0 who are holding out for bootloader unlock.

Are there any TOT files available? I've bricked my G4 and am hoping to recover using them. I can only have it recognized as qualcomm 9008. It's the EUR H815.

Sadly no TOT`s yet. Did you even try the kdz method?

Yes, I tried. But I am bricked beyond being able to get into download mode. Have to use something like boarddiag to get the partition table and download mode loaded to the device. Unfortunately, boarddiag for G3 doesn't seem to work with G4 (I was up late trying it last night), so I might have to wait a while for new unbrick tools to come out. At least iPhone 8.3 jailbreak came out so I have something to play with

Exactly. I usually download it from my phone when away from my home and then transfer the kdz to my computer at night. They usually take like 2 hours to download. But if you don't want to fix that link, then thats ok too.

Its not simple to edit a large OP with a mobile phone ;p. I have fixed it now. But downloading firmwares using a phone, (unless your using a download manager) is not really recommended.

CamUIX V4 Custom Rom LG G4 H818P/H818N (W/O Recovery & bootloader Unlock)

CamUIX V4 - alpha Mod
CUSTOM ROM for LG G4 H818P/H818N
there is no separate threads not available for LG g4 Dual's Custom Rom, that's why i have to write this POST
its not my work. its a hard work of our Russian friend DS-302 . i just explain what have done to my LG G4...
all credits go to him.......
Download "LG Root" here: http://d-h.st/uO8h
CamUIX V4 alpha Mod is looking good.....CamUIX V3 is Great....
DOWNLOAD THE LATEST SYSTEM IMG OF CamUIX V4 Alpha Mod from here:
https://yadi.sk/d/R2XNzcyftmC7M
DOWNLOAD THE SYSTEM IMG OF CamUIX V3 from here: ($$ Try This Always $$)
https://yadi.sk/d/5_qHqvukrkkbz
Move the downloading "system.img" file to the root of your phone's internal storage
Once this has been done, POWER OFF your phone normally and disconnect from PC. After LED stops blinking (OFF properly), Hold the UP VOLUME key and re-insert the USB cable from your PC to your phone. If done correctly, you should see DOWNLOAD MODE in small font in middle of the screen. it will then display another screen with text: FIRMWARE UPDATE (a USB logo) a warning to not unplug and a status bar at 0%.
On a windows PC, Start a command prompt (Start > Run > cmd) and navigate to the unzipped contents folder of LG Root (which is downloaded for LG g4 Root process). (On my PC, the command prompt line after navigation to my unzipped folder looks like C:\Users\star\Desktop\LG_Root\ ).
Let's verify the COM port your phone is connected to. double click the file "ports.bat" in LG_Root folder. Look for the COM number that corresponds to "DIAG1". **WRITE DOWN / REMEMBER THE COMM PORT NUMBER!** Let's assume it's COM3. Click any key/exit this window now...
copy/paste or type this command MAKING SURE THE RIGHT COMM NUMBER IS ENTERED: Send_Command.exe \\.\COM3
You should see Author: blog.lvu.kr and SPECIAL COMMAND : ENTER, LEAVE on 2 lines followed by a hashtag (#). If you are up to this point, type id and press ENTER
You should get back some text starting with "uid=(0)root gid=(0)root".
If it worked for you, from here run the command below (copy/paste next to the # and press ENTER)
dd if=/data/media/0/system.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
If you've done this correctly, as soon as you've pressed ENTER, you'll see a blinking cursor, probably for a few minutes. Basically the pre-rooted system image you are FLASHING to your phone is being written, so it may take a few minutes. When complete, you should see #. If you see this, it's DONE! Type LEAVE (in CAPS)and press ENTER. Your phone should then restart... Here's mine, it worked like charm!
hit "THANKS" button on this post if this has been of assistance to you...

I directly flashed CAMUIX3 (Dirty flashed) and initially had FC's but after a hard reset all's fine........ but have noticed the battery drains faster but I could live with it as long as the cam and sound (dolby and viper) section is good..... thanks for the wonderful rom guys......
Any help on battery drain is much appreciated.

I have both MetroPcs and t mobile. If you want you can try using LG Bridge to update the phone, basically does same thing but it's more user friendly and it always downloads right package. But to recover from brick I think LG UP only way to it.

i wanted to give the t mobile firmware a shot and i don't think it would work though any official tools, 1) i haven't got the update that t mobile has as far as i can tell(is it just a security patch? or a os update?) 2) i'm really hoping the flash will let me bypass the metro hotspot check, right now i can only use pdanet+ works great but i want proper hotspot past my 8GB. it's up to you i'm just asking if i can be posted, any help is good help dont want to ask for to much.

That does not seem safe at all. That sounds like you could brick your phone. You should never try firmwares for different models. If you want upgrade use correct model. MetroPcs is k7ms330.

yeah i know thats why i wanted to use twrp, i already have the version with the button combo and as long as i dont flash the recovery i wont have a issue with restoring, hardware wise they are the same and i've done the same with galaxy s3's and 4's between [email protected] and T-mobile also done this with some LG optimus F(and some number 90?) between boost and sprint so i know it's possible and as long as recovery is accessible it should be alright

I think it's on the PC. Why would it need internet on the phone? If you can get the download link from the log, that would be great. I still need for that model. I'll search for it.

I hope its not just my phone but...
I have the MS330 (Metro) and i followed the steps. Worked just fine. But im having issues with the phone. Actually its just one MAJOR issue. SEVERE battery drain and, may be bad to say it this way, but i hope someone else is having a problem too. I really hope this is a Metro KDZ problem and not my phone going bad. I know its not the battery itself because i have used 3 different batteries, one being brand new. And this is my only phone. I need to figure out how to fix the problem. I think its ***10g update LG supplied. And i need to find a way to go back to the original stock system before this. I think it was ***10e. Does anyone have a TWRP backup? I cant take this battery drain. Please say something if you had battery drain also.

I've heard having KingRoot instead of SuperSU kills battery. But I'm not sure. Pm @goitalone I think he knows of unofficial kdz with the old version. If he does, please send it to me so I can post it here.

I always replace kingroot with supersu. It always replaces and fully removes kingroot. I flashed twrp beta 1 and it works just fine. I use adb to restart to recovery and do what needs done. And i have busybox installed and i use xtreme booster. Thank you for that info though. I have seen the battery drain with kingroot. I will pm him and see what can be done thank you.

You could reflash KDZ and use this method to root, IDK if it will help http://forum.xda-developers.com/android/development/root-lg-k7-install-supersu-kingroot-t3413941 Make sure you boot into recovery instead of flashing. Root it then you can flash.

[Guide] LG G5 Back to Life [Download mode] [LG Flash tool] [Unknown model in LGUP]

Overview::​Well, something bad happened to my phone (H830), then LGUP said unknown device. I tried many tools, different KDZ but all went failed
What Actually happened in my case:​
I had mm stock 10d ROM then I upgraded to 20a using LGUP KDZ method by using uppercut trick. I wanted to enjoy Fulmics 1.5 (for my H830), but was newbie so had no idea about rooting it and installing (Because all available guides were actually complexed or I was impatient to read other things except main procedure). So I did something strange and Fulmics was installed over 20a ROM, because I was unable to wipe internal storage due to that decryption thing.
So I thought, I should go back to stock by using LGUP and retry the procedure with more focus. This time LGUP didn’t know my phone, not with that uppercut too. I thought that’s because I unlocked bootloader and must first try to lock it, and try again with LGUP. I retried with locked bootloader and failed again.
(Remember, LGUP or any other tool have nothing to do with back to stock thing. You can go back to stock whether you are bootloader locked or unlocked, it has no power of stopping you.)
Possible Cases:​So I will not waste the time. Possible cases:
1: LG G5 stuck on download mode and it is now not being recognized by LGUP and you can’t do anything, because no other tool is available.
2: You installed a custom ROM and now LGUP is not recognizing it. You want to go back to stock and can’t do it.
3: Anything bad happened during flashing process, PC restarted, phone went off or whatever. And now you can’t bring it back to life.
¬ Or
Other cases you faced.
Read 4th post before proceeding,
Before asking a question, first, see FAQ in 3rd post. In that way you can save a lot of time.
For Video Guide refer to 4th Post
Things You need:
​1: LG UP
2: Uppercut
3: Drivers
4: Stock ROM for your device.
All Herehttps://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295
5 : LG Flash tool (the one used to bring LG G2, G3 back to stock).
I used 20a KDZ because I had it already and it was nougat with vulnerability to root and flash TWRP.
6: LG Firmware extract tool
In 2nd post
Most tools can be found in attachments of 2nd post.
Process:​
First:
Uninstall all other tool, previous driver (including other phone’s too). Restart PC
Just to avoid problems. I tried this process many times on Windows 10 64-bit and it always worked for me. So it has no problems with new Windows OS.
Now follow procedure in exact order.
1: Install LG drivers.
Put Phone in download
(Hold Vol+ and connect to PC while it was powered off).
Wait until it finishes installing drivers. Change COM Port to 41.

( Refer here for changing this, If you can’t understand that.)
Now DC it from PC and keep it staying in Download mode.
2: Install LG Flash tool and copy megalock.dll to installation directory or it won’t work.
3: Install LGH-H830_DLL, LGH850_DLL and LGUP_Store_Frame_Ver_1_14_3.
4: Extract LG Firmware Extract and copy Stock KDZ to that folder.
5: Run WindowsLGFirmwareExtract.exe
A: Click on “KDZ file” open and select stock KDZ.
B: Mark File Name. It will select all files. Click on extract KDZ button. Wait till finished. Now quit the program.
6: Run LG Flash tool. Select Manual mode. Click “…” for dll and select LGUPc.dll from that KDZ extracted folder.
A: Click on add button of S/W, Select “All Files” from pop up window. Now ““.KDZ”” file will be shown, select that ““.KDZ”” file, press open button, click on “OK”
B: Begin download by pressing that big “Yellow Right Arrow”. Wait until it finishes loading.
C: Connect phone when LG Flash tool says “Waiting for connection”. Make sure phone is in download mode and COM port is 41.
D: After a while it should fail the process, that’s fine. Just DC Phone, do not turn it off.
7: Exit LG Flash tool and Run it again. Select Manual Mode. This time select LGUP_H830.dll (Select as per your model e.g H850.dll for International variant) from LGUP
(Download it from 2nd post, then extract and select as dll for this step only.)
Folder. On S/W section first click on “Remove All” to erase old selected KDZ from tool and select “.DZ” (not “.KDZ”) as S/W from extracted KDZ ROM.
A: Press ok, Select on big “Yellow right arrow”. This will be loaded quickly. Connect the phone again. This time the process will get started. Wait till it gets completed.
Note: This flashing process will go up to 150% so don’t get nervous or don’t DC phone.
B: Phone will be restarted automatically. A big “2” will be shown. Wait till it gets converted into “3” and tool will say pass.
if so pull battery and start phone normally.
Or
If it is not converted into 3: Happened to me for first time.
(First Quit LG Flash tool)
Pull battery, reboot again into download mode. Run Uppercut, say “Yes” to consent, LGUP will be started automatically, Now LGUP will recognize the phone. Click on upgrade, Press “…” and browse stock KDZ ROM and select “.KDZ” stock ROM (not “.DZ”)
Select Upgrade because Refurbish won't work with uppercut.
Press Start. Download will get started. Wait until it finishes. Now Your Phone is back to life.
Ask If anything wrong happened, I will try my best to help. I used this method on my device, LG G5 T-Mobile variant AKA H830. It should work for others.
Hit Thanks, if I helped you.
If I forgot to give credit to anyone who is related with these tools, please let me know and I will be happy to name them.

Attachments. See below.
LGUP_H830.dll is for H830 variant only. You need .dll file specified for your variant.
LGUP_H850.dll --> Here
Either Download files from Attachments or Use MEGA mirror
DLL for other Variants
To get dll for other models please refer here
(This doesn't have dll for all G5 variants but should ease to some users) (Huge thanks to @codefire for awesome website)

FAQ​
I got confused on which Flash tool to use and with this megalock stuff?
Ans: Thanks, you asked, Just download LG Flash Tool attached in 2nd post, unzip, install tool, there will be a megalock.dll too, copy that to installation folder (by default that's "C:\LG\LGFlashTool") and overwrite, (written in install.instructions too inside zip).
This method isn't working for me, what shall I do?
Ans: The possible reasons, for that not working, might be,
A: You didn't installed drivers properly, try uninstalling old drivers and restarting after that.
B: LG COM PORT isn't set to COM41, here is guide for that.
C: And Most important, You are not following steps in the order in which they are written, so read carefully.
I followed the method and now my phone is totally live but now I want to root my device and have TWRP, so I can have full freedom with this phone. Can you give me any thread for that?
Ans: Nice question. There's a lots of nice threads out there here's a thread currently covering H830 only but you are welcomed to try this on H850 and let me know if this works so that I can update the thread.
Can I lock my bootloader again so I can take OTA updates?
Ans: First of all, always remember, bootloader has nothing to do with OTA. It means that if your phone is flashed with stock rom without any root or TWRP and bootloader is unlocked, you can take OTA uodates without any brick. So there is no connection between OTA and bootloader.
But if you still want to lock bootloader, here's the process. Make sure drivers are installed and minimal adb & fastboot is installed too.
Take battery out, put it back, hold vol- and connect phone to pc with data cable, it will boot into fastboot. Enter command in adb & fastboot cmd windows,
Code:
fastboot oem lock
fastboot reboot
Your phone will now try to boot into system, if stock rom is installed phone will boot without any issue else you will have to flash stock kdz again.
Where I can download stock KDZ or dll for my LG Phone (other than G5)
Ans: Most LG Phone KDZs can be found at this website.

Have you followed it as described. You have to do the process 2 times with lg flash tool and after that with lgup (only if you stuck with big 2).
Please read care-fully..

Finally, it has come back to life. I retried it using LGflashtool but this time I used stock Nougat rom for Vofadone UK cos my phone was simlocked to Vodafone UK. I was using MM rom for 3 Networt cos I wanted to install xposed framework which aint compatible with Nougat.
Thanks to everyone who helped to make my phone come back to life esp the created of this thread.

Good luck with that. :?

OP, I would like to make a suggestion. Could you please include screenshots to illustrate the steps. That will help people to better understand the steps and to make sure no step is missed as this is happening to lots of people lately. With that it will save you from replying to posts of missed steps and make the thread clean. Thank you once again.

[Guide] How to ROOT + TWRP + Install Nougat on Canadian LG D852

*** Important: Your Warranty Is now Void. Always take a Nandroid backup. I am not responsible if you damage your phone or lose any data***
Hello everyone. I created this guide for the Canadian D852 since I didn’t find anything that was straight forward. Credit goes to all the developers who made it possible for us to keep using our beloved LG G3.
This is my first attempt to create and share a guide. I hope it will be useful to other users. If you find any error or have suggestions, please send me a message.
Download all the files before you begin. Do not forget to copy your ROM and GAPPS to your SDCARD before you install TWRP.
Go back to Lollipop using LGUP **Always use USB 2 port. It won't work with USB3**:
Download your kdz (d85220… not d85230). I downloaded mine from:
https://lg-firmwares.com/lg-d852-firmwares/
Follow these instructions (works with D852 don’t worry):
https://forum.xda-developers.com/showpost.php?p=64624353&postcount=3
Choose the kdz from your provider. For example, I have an unlocked Fido phone but I want to use it with Bell. So I used the Bell 20k KDZ.
When selecting a file to flash, type *.* and press Enter in the filename for your .kdz to show up. If you do not, it will only show .tot.

Root your phone using this method:
Enable ADB debugging.
Unplug usb cable.
Go to Settings > About Phone > Software Information and tap build number until you are presented with "You are now a developer".
Back to Settings screen.
In Developer Options, enable USB Debugging.
Connect usb cable.
Click OK when asked to allow USB debugging in android.
I use the root.bat method. If it doesn’t work go back to step 1 and try again.

Install TWRP using Autorec:
Copy the rom and GAPPS to your SDCARD before you install TWRP.
Download the file from here:
https://mega.nz/#F!rtI1naZT!LJIKUVpv8fYjrvhpykA4_A!2o433RBZ
Transfer the file to you internal or external SD card.
Head in to Settings -> General -> Security, then scroll down until you see Unknown sources. Tick the checkbox, then hit OK on the next prompt.
Install APK via the file manager.
Open App.
Grant root access.
Wait a few seconds while it does some backup.
Wait for prompt to say that it is ready to flash.
Click the button to Flash TWRP.
Wait for it to be done.
Phone will reboot into TWRP
Update TWRP to the latest version if you want.
Download and install Nougat rom. Tested with CrDroid v3.6 and open_gapps-arm-7.1-nano.
https://forum.xda-developers.com/lg-g3/development/rom-crdroid-t2955012
http://opengapps.org/
**I’m not sure if it’s necessary but I did it anyway** Flash Dene Hybrid Baseband via TWRP (don’t forget to wipe cache and dalvik after) if necessary (mobile data is unstable etc…).
https://mega.nz/#F!rtI1naZT!LJIKUVpv8fYjrvhpykA4_A!2tJFBLLK
Source: https://forum.xda-developers.com/lg-g3/development/canadian-d852-stock-bumped-rooted-rom-t3056843
That’s it! Enjoy Android Nougat!
N.B. That is the only way I was able to get a stable mobile data connection. Only flashing baseband did not work for me.

Thanks, barguin, for a very informative thread.
How is the battery life on this Nougat ROM? I will be switching from Fulmics MM, and my provider is Fido.

Battery is very good. I can do a full day easyly.
Regards!

@barguin: thanks for the quick response. Did you try Exposed for Nougat? I know that Exposed is frowned upon in the CrDroid thread, but there are a couple of modules I would like to try. Thanks.

I do not use exposed...sorry.

Thx

Personally I had some problems with lg flash tool.
There is no need to enter download mode! LGUP will do it for you.

I read the heading in this thread and it said something about not downloading the D85230 file .. and my phone is D8530g as shown in the screenshot .. so is the D85220 file gonna damage my phone .... Sorry for the newbie question !
Sent from my LG-D852 using XDA Free mobile app

The D85220 file will not damage your phone. Instead, that file will install an older Android version on your phone, namely Lollipop (this step is required to gain root). You are currently on Android Marshmallow, and you will end up with Android Nougat if you complete all steps correctly. The procedure is meant to work like this, one step back, two steps forward.
The "20" or "30" in the file names (on that website hosting KDZs) have the following meaning:
"20" = it's a Lollipop file
"30" = it's a Marshmallow file
"40" = it's a Nougat file (I can only wish, there is no such Nougat file).
But seriously, the procedure requires more than a modicum of familiarity with flashing and with using various pieces of software. There is potential for bricking your phone.
No offense, but, judging from your question, I would suggest that you should enlist the help of a friend who is a bit more knowledgeable on this topic.

Guys .. Can I use the ROM on D855?! If not, so how to flash the ROM without getting any issues?!!
Thanks.

Do not flash the rom on the D855 it's only for the canadian variant.

Did this on my d852 and it's stuck booting on Oreo, Nougat, and stock Lollipop. Happened after I installed TWRP, any fixes?
edit: i think it was the roms.. got 3 bad ones i guess lol. fulmics worked.

Just an FYI, I followed the LGUP instruction for my Bell D852 but it was soft bricked, doing the flash using "refurbish" instead of "upgrade" did it for me and I was able to finish rooting my device!

How to root symphony i60.... please reply me

my phone no sound
I do not hear sound from my phone after installing CRDroid. the programs are working. YouTube is opening but I can not hear the sound of the media being played.
I do not hear the sound of the media played when I plug in the phone.
please help me.

Thanks alot man, this was super handy!
Edit: Seems I've got that problem where shutting the phone off bugs it and it won't turn back on unless you remove the battery and put it back in. It also resets the time. Kind of annoying. Seems to happen to some D852s after installing TWRP.
