LG G5 Brick after root - LG G5 Questions & Answers

Hey Guys,
i think i just bricket my new G5 after i tried to root it.
I used this method:
I unlocked the bootloader with the unlock.bin i got from the lg-website, installed the newest twrp and installed the newest supersu.
Then i wanted to reboot but it didnt work and my phone said analogously that my phone cant be trusted and wont work.
The phone didnt boot but seemed not to be in a bootloop.
After that i rebooted into recoveryy and entered the following code in the terminal:
dd if=/dev/zero of=/dev/block/platform/624000.ufshc/by-name/misc
I did this cause it was said unter a yt-video and seemed to work.
Now i have a bootloop and my phone says this:
[910] boot verification fail!
[960] - cause : mismatch_sig_len
I googled this error-code and wanted to install the firmware via LG UP, but when i want to start the software it says that there is no handset connected.
And i really dont know what to do!
Please help me.
PS: Its still possible to start the fastboot-mode and my pc ic detecting it.
But its not possible to flash the unlock.bin again.

Try flashing the complete system with the LG UP method in the 10C thread or with the LG Flash Tool provided here

I tried it with the lg up software.
The software detects and connects to my phone and says, that the 10d-firmware is installed.
When I selected "upgrade" (although it should be a downgrade) and the downloaded 10c-kdz-file and click start, it runs to 9% and chancels with an error-code:
Error: Error Code = 0x81000304, CBasic::_func_LoadGptF - Errorcode:8224
Google wont helps :/

I'm pretty sure there are 2 commands:
dd if=/dev/zero of=/dev/block/platform/624000.ufshc/by-name/misc
dd if=/dev/zero of=/dev/block/platform/624000.ufshc/by-name/fota
reboot

Thats not possible in my opinion, becauce when i want to enter the recovery the phone comes into the bootloop after i made the usual wipe.
Is it possible to do this from the computer?

Use command adb shell fix:
adb shell
su
dd if=/dev/zero of=/dev/block/platform/624000.ufshc/by-name/misc
dd if=/dev/zero of=/dev/block/platform/624000.ufshc/by-name/fota
reboot

It was possible for me to flash the Stock-Version and tried your two comments after unlocking the bootloader, installing the recovery and super su, but the same problem came up.
Now i dont know how to root my phone.
It doesnt boot and just says "Your device software cant be checked for configuration".
Problem solved:
I didnt use the newest Version of SuperSu, not it works great

Same here ... I'm on stock 10c and tried to update to 10d but I received same errorcode at 9%. I think I use latest LG UP 1.14. Any solution?

I solved the problem. I have just updated all LG file. LG UP, LG Lab, LG 850 DLL. Finally I successfully updated my phone.

I'm also stuck at 9% with this same error message. Can you tell me specifically where you downloaded the updated LG files that got you around this?

[p769] rooted, think I softbricked my phone

Hi,
I'm not a newbie to Android by any measure, but this is my wife's phone, not mine (I have a Nexus 4) so I'm not familiar with a lot of the LG stuff.
Anyways, I rooted her phone to get rid of some of the bloatware and the stupid Qslide thing, and also to edit the build.prop so Netflix will have the Chromecast button. I had deleted quite a few bloatware system apps, and rebooted, everything was fine. I deleted a few more, then edited the build.prop. Rebooted.
Now it shows the LG logo, but then the screen goes blank, but is still on (you can see the backlight) and never boots. I only removed a few more of the LG and Tmobile apps and edited the model and manufacturer in the build.prop
Do I have any easy options to fix this? Or do I need to flash the KDZ?
Flash kdz then install cwm then backup the stock ROM THEN do your mods. Every time every phone. Good luck

Yes, offline flash the kdz. Always backup your rom whenever you so something like that.

If it's just the build.prop causing it not to boot, you can flash (with fastboot) the boot.img for the kdz you are on. Look at my signature on how to extract it.
If that doesn't work, flash the ice cream x & u partitions for p769 in fastboot, and then run offline flash

Thanks for the suggestions guys. I've tried the offline KDZ flashing it, but I can't get my computer (tried two actually, mine and my wife's laptop) to do anything once its in the S/W Upgrade mode. I used the method previously to update her phone the JB when Tmobile pulled the update. Since then it downloaded the most recent OTA. But anyways, I don't know why it wont work. It just continally tells me that my phone isn't connected, even though I'm using the latest drivers and the phone shows up correctly in the device manager. It's driving me nuts since it worked previously!
Any ideas?

Sorry I didn't break it down enough for you. You have to get fastboot up and running. Jellybean does not operate when starting in S/W mode, that's why you get the connection problem. Now ice cream, does operate when starting in the S/W upgrade mode. With fastboot you can flash everything you need to get the offline flash working. These three links are all the info you need.

Factory LG mobile support tool has an option to "update recovery" in top right menu. This will download latest factory rom via internet and reflash phone in software update mode to reset everything.
http://www.softpedia.com/get/Mobile-Phone-Tools/Others/LGMobile-Support-Tool.shtml
Works well.
might have to set phone into software update mode by pressing vol up and then inserting usb cable..

Ok, I got the timing down and fastboot seems to come up, but after I can see the logo on my phone with the v 0.5, the script just says < waiting for device >. Thats where it should flash the ICS xloader? Or am I missing something and I should flash the JB images with fastboot? Where can I get the images?

Mirrored Screen and Touchscreen issues

I have been looking EVERYWHERE for a solution to this. I followed the {Unlock Bootloader for Noobs} to the letter http://forum.xda-developers.com/showthread.php?t=2277639
I get to where in the video guide the screen become's inverted and the touchscreen is all over the place. But I can't get my phone to boot into recovery. I have tried every single guide to no avail. I have the LG L9 P769 with Tmobile.
And right now my phone is useless.
Just a tid bit, when it first boot's up both the logo and everything is backwards, but if I suspend it and bring it back up, its all back to normal but the touch pad is still goofed up.
Any help would be greatly appreciated.
You need Roberts busybox installed, artas182x cwm install, and flash the fix with cwm.
You need the v6 bin the directions are with it.

I rerooted the phone, installed SU, gave root access to the recovery when it asked, installed and clicked "Boot into Safemode" and it did the exact same thing it always does.... nothing, it simply rebooted the phone to main screen, Even tried holding down the vol- button during a boot.. nothing. it only goes into safemode.

Do you know how to use ADB with your computer? Do you have android debugging enabled? Do it the old way
First extract the v6.bin to you SD card (external_SD). Open adb and enter the following
Code:
adb shell
su (give it root access on your phone, good luck)
cat /storage/external_SD/v6.bin > /sys/devices/virtual/input/lge_touch/firmware
once you do that the shell will freeze (can't use it anymore) So open a new cmd and enter this
adb reboot
This will fix the problem. Now go thank Lelus :thumbup:

I did just as you told me to, I copied the v6.bin to my external sd card, started up ADB, put in the commands but once I entered SU and gave it root on the phone the terminal stopped and would not allow any more commands, I rebooted and tried again as well as rebooting the phone. I am unable to enter the command to transfer the file.

You might have thought you gave it access, but actually denied access. Try to open supersu, and check if adb was given su access.

I checked supersu and it show's as given root access. And when I put in the SU command into adb it show's on the phone as giving root permission's via popup. And that's where it freezes.

Thanks! This fixed the touch screen on P769 Tmobile. This is after using the LG support tool to update back to V20f from a failed attempt using carloswii5's noob guide. Could not get past "adb reboot oem-unlock."
If anyone can point me in the right direction to get the LG boot screen back to normal (not inverted/mirrored) i would appreciate it. -----Update:found u-boot.zip fix for boot screen.
Thank You!
Thank You!
I had given up on this a year ago, I tried it again on my phone and it worked!

Can't boot into Recovery, Bootloader, Download, or Fastboot! Why?

I have an LG Optimus Fuel (LG L34C) from Straightalk running Android 4.4. This phone is (as far as I know) the same as the LG Optimus Zone 2 from Verizon Prepaid.
I couldn't find a halfway decent manual for the LG L34C so I followed the LG Optimus Zone 2 Manual to enter Recovery mode. When I held the buttons on the L34C, it would boot, show the LG logo, then shut off, show the LG logo, and do it again. As long as the buttons were held in would loop.
So I downloaded the ADB and tried to do it from there.
"adb reboot recovery" brings up the classic "No Command".
"adb reboot bootloader" just reboots it.
"adb reboot download" just reboots it.
"adb reboot fastboot" just reboots it.
What the heck is going on! I'm going crazy trying to figure this out. Why can't I access any of the special menus?
Oh, and TowelRoot didn't work to root the phone either.
I tried to enter Recovery Mode on my Nexus 7 (2012) and noticed that I also get the "No Command" prompt. I was then able to hold 'Power' and press 'Volume Up' to enter Recovery mode.
I tried this, and every other imaginable button combination, on the LG Optimus Fuel and had no luck whatsoever.
Is it possible that this stuff has been disabled by LG?

Is your device activated. Straight Talk said that reset via recovery (it's in the phones manual...) would work after activated, but that seems like BS.
full user guide from LG
Okay I got the full user guide that was NOT included this is the LG Full guide. Just Click it, had to put it on 4shared as it is too large to upload as .pdf on here.
Root worked for me after I followed this guide. http://www.androidarea51.com/all-things-root/working-root-for-lg-optimus-fuel-woot/ Make sure you change the values in post #1, and remounting /system as explained in reply #1.

now that i think about it my device was bricked.... maybe this is a special recovery designed to act only when problems are detected in the boot sequence?
Well, looks like I'm in the same boat now, lol. Going against everything I've learned in the 5 years messing with Android, I had a non-thinking DOH! moment and changed the screen density. After reboot, I just have a bootlooping cheap paperweight for the time being. I can get into recovery, but there's no menu options. I am going to try to push the backed-up build.prop.
They really have this one locked down. I haven't found an OTA zip in my searches yackaro, but I'll keep an eye out for you.
root for lg fule kinda works
I got an lg fule from walmart and decided to root it(never done it befor on any thing)I tried for at least 6 hrs and tied poot z4 all kinds of apks and finely I get towelroot to work but I cant get full acces its says setuid attribute is NOT present BUT root user ownership is present. root access is NOT correctly configured for this file! what is wrong and what do I need to do? I have been using the phone for a week downloading apps from blackmarket and googls app sometimes its kinda slow but It wont let me move systems apps to sd,can delet but not movei have titanium bu supersu busybox pro force2sd esfx and rommaneger how or can I gain full root for kitkat 4.4 lg fuel?
It is possible that TracFone (StraightTalk is a subsidiary of TracFone) is using special bootloader code to lock users out of recovery mode. I know that T-Mobile did something like that with some lower-to-mid-range LG phones.

I can't (well, couldn't - I'm soft bricked right now) even boot into bootloader. To get full root, I think we need an unlocked boot loader. However, "ADB reboot bootloader" doesn't work, right now, as well as most of all the other commands.
I was able to reboot into recovery, but there wasn't any text. I'm working on getting the fuel booting again, but I haven't found anything that works yet. The hard key combo that LG describes to hard reset doesn't work. And I've tried many other hard key combinations, but nothing works so far. [emoji20]

Yes, what I meant is they might be blocking both recovery, and boot loader mode...

True. They probably are. I don't know why they would block at least hard factory reset, though. But then again, since we paid for our device (albeit only $30) seems like we could have more freedom with it. Oh well.
LG has fastboot locked out. I was browsing the LG G2 forums when I found that people are able to get to fastboot by zeroing out their 'laf' partition and forcing the phone into fastboot (because aboot can't find it) where we can then flash a custom recovery.img hopefully. I have the recovery partition extracted and replaced /sbin/recovery with CWM and repacked. I just need to get into fastboot to test it. I will get a second phone from walmart to dev with, they're only $30. if anyone has a dev phone to test it on, read on...
This is theory and hasen't been tested. We may not even be able to run custom recovery or fastboot.
If anyone wants to pick up here be sure you have fastboot and adb installed and have some dev knowledge, not for noobs like me.
backup your laf partition to an external SD card (insert a micro SD)
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/storage/external_SD/laf.img
pull laf.img to your computer as a backup and to use later in fastboot
wipe your laf partition [I AM NOT RESPONSIBLE IF YOU KILL YOUR PHONE]
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
reboot your phone and connect it to your computer.
your phone SHOULD (I have not tested this) boot into fastboot as a failsafe.
on your computer
Code:
fastboot flash laf laf.img
Code:
fastboot reboot
phone should reboot back to normal.
This will test that we can in fact get to fastboot.
STOCK laf, boot & recovery files to look at. The included repacker does not repack the images properly. I use linux tools for repacking.

Sounds like we are a little closer, however you can push a .img thru adb already I know some people that did a mako build only problem is it bricked it.

It's the new security features of kitkat. Only allows apps to access their own folders. Try SDFix (root app from play store ). I now can read, write, copy to/ from sd or system.

Some things that I noticed that were missing (besides /sbin/recovery). There is no flash_image, dump_ image, or erase_ image in /system/ bin. Usually use flash_ image in terminal or in fastboot. Don't know if these binaries are generic, or device specific (partitions). Could copy from other device, but don't know if they will work properly. Glad I'm not alone in this.

I pulled the one in the Zone since that phone is most similar to ours, However I have a feeling the key bindings won't be correct, so I may still have to compile from source. I pulled the git for TWRP but haven't made changes to it yet. Its been a busy week at work and its only monday.

Those also don't exist in the stock recovery for the Optimus Zone. It looks as if busy box was added to the Zone CWM recovery now that I have looked at it closer. Its been a WHILE (Samsung Vibrant with Team Whiskey) since I built a recovery image.

Yeah, we might only get one shot at success (before jtag ), so it's probably best to compile from our recovery and source. I used Apktool to decompile recovery (dd if =dev/ block/ mmcblk0p17 of =/cache/ testrecovery/recovery.img). Ramdisk has./ sbin/recovery. Copied that to /Sbin/ . Disappears after reboot. Haven't yet decompiled boot.img. Hoping to find "boot", and fastboot. More later.

Do you know anything about the Loki tool by Dan Rosenberg:
https://github.com/djrbliss/loki/blob/master/README.txt
Have to admit that I'm not quite this educated, but that looks promising.
Edit: This is like having to root your phone twice. Lol
EDIT: Don't nuke laf yet! I dd and decompiled it (had to rename it to boot.img in Apktool). There are some interesting images (png) in res folder. I'm gonna dd aboot and abootb, and see what's there. Gotta go to work soon. Probably more tomorrow.

Thanks for all your work. Im also very interested in being able to boot into stock recovery. Mainly to be able to preform a factory reset. Do you know of an alternative method to do a factory reset at this time since booting into any recovery isnt possible ATM?

TWRP is not working (pink screen)

Hi, I found out that there are official cyan roms now and I wanted to test them. For root, I installed kingroot app. Then I used the app flashify for flashing newest TWRP (from this forum) on my device, and it also says it is done, but after reboot, i get a pink screen with some kind of ram dump text. I can restart into normal android from g2 mini, but I want to use marshmallow.

Well u need to install busy box first, and install the terminal emulator.
Download the 2.8.7.0 twrp IMG from here
http://forum.xda-developers.com/attachment.php?attachmentid=3385522&d=1435697303
Place the file in the root of the SD card and open the terminal emulator and run this command.
su
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
Wait till whole process is over and then type
su
reboot recovery
That's all.

Ok, to unlock the bootloader download the aboot.img from here:
http://forum.xda-developers.com/g2-mini/development/bootloader-unlock-t2827748
And rename it as aboot4.img
And then open the terminal emulator and type this code:
su
dd if=/sdcard/aboot4.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot
There's a video on YouTube about the whole process, I would suggest u to watch it before u perform it.
After bootloader is unlocked, use the first code that I gave u to flash the recovery accordingly.
If u find any difficult then quote me.
Best of luck??

LG G Watch stuck on fastboot menu

Hi there guys,
I'm new to the forum so apologies if this has been posted in the wrong place.
So I was directed to this forum to attempt to solve a different problem but in my hast, I have caused an even bigger problem!
So initially I was having problems with the new Android Wear update with regards to rooting, so I wanted to find a way to roll the software back or restore the device to stock.
I came across this post http://forum.xda-developers.com/g-watch/development/tool-lg-g-watch-return-to-stock-t3158349 and attempt to do as advised, but half way through the process, the program froze. I then tried to reset the watch from the button at the back, but the watch is now stuck on the fastboot menu. I used ADB to see if I could still connect to the device but no devices can be found.
I have checked the device manager and can see the device as "Android Bootloader Interface" but can't seem to get it past the fastboot menu.
Any help would be much appreciated.
Thanks in advance.
just do it again, as long you can get fastboot, you are safe.

The problem is, the program requires a connection via ADB, but ADB can no longer see the device. So when I try to run it again, nothing happens :/

F the program it is outdated as **** get adb minimal here and the last 5.1.1 images here
Extract to the same folder you put adb minimal and open a terminal here.
do these commands:
Code:
fastboot flash boot nameofboot.img
fastboot flash system nameofsystem.img
(optional) fastboot flash recovery recovery.img
fastboot format/erase data
fastboot format/erase cache
Oh yeah btw if the only problem you had was with rooting just use my guide here and system images from here instead

Looks like it is either that adb minimal is messed up (I use the full 1gb sdk) or there is a driver problem or you can try running cmd as administrator instead

I did try adb from the SDK that you've mentioned and have had the same results.
I also run in Administrator every time.
What I have just noticed with regards to the drivers is the change in the name of the device in device manager. Previously it showed as "Android Composite ADB Interface" but now it is showing as "Android Bootloader Interface".
I believe that might just be because the watch is stuck on the bootloader menu so that is how it is displayed, but it could be the cause.

Hi there,
I've just tried to update the drivers but they seem to be up to date.
Yeah, the only reason I thought the program had done some damage is because it froze which resulted in getting stuck on the fastboot menu, but you've more knowledge so I guess that's not the issue.
I'm not entirely sure what else can be done here. I think I might have to just get another watch and stop the update as that is when all the problems occurred.
If you can think of anything else to try, I would be willing to give it a go but don't worry yourself too much if you're out of ideas.
I really appreciate your help up to this point anyways

The first attempting of flashing anything to this device I believe was when using the Return to Stock tool.
I choose the "Install ROM" option which I can see from the script attempts to flash.
So I guess it's never been successful on this device.

This whole problem started due to the fact that I couldn't see the device using ADB, so I tried to look for a method to solve that which then caused the problem I'm having now.
The only variable I can put it down to is an update that was pushed to the watch as prior to that, I had no problems at all.

After all of this, it was the drivers...
I don't get it though!! I tried to reinstall them before and nothing changed!
It's only when I completely deleted them and reinstalled that it worked.
Honestly dude, thank you so much for your help and patience. My watch is now working and paired with my phone.
I'm waiting for it to sync but hopefully I will be able to run ADB and all will be well again
Thanks you so much again.
