[Q] LG G2 bricked and can't flash stock firmware!

So I'm really into Android developing, I'm always flashing and installing etc, but I got a problem now.
Phone information​
LG G2 D802
Rooted
TWRP Recovery 2.7.0.0
Was running 4.4.2, found a kdz file on the internet and flashed it (no regular update from my phone)
What happened​I actually did something stupid, I received an application update from the LG Download Center (or whatever it's called) on my phone and clicked on it. I was planning on flashing Android 4.4.2 again because my firmware was not stable, and I thought this update could help me.
But no, after it finished downloading, I automatically booted into recovery.
What I did​So I tried to reboot and enter my OS, but unfortunately, I was stuck in recovery.
I did everything I could, wiping (Dalvik) cache, factory reset, flashed a new rom, restored Nandroid backup, but no, every time I booted, I got back into recovery again.
I only saw 1 option left, booting into download mode and flashing a new firmware.
I found the Netherlands 16GB kdz file for Android 4.4.2 (because I had a French one first), the one I was looking for.
Looked all over the internet, and all guides pointed me to this guide.
Tried it, but I got multiple errors, one of them was that my phone was not connected while I was at 15% of the flash process.
What happened​After that first flashing process, I booted up, but got a Security Error. After the Security Error was showing for 5 seconds, my phone shut down. This is happening every time I try to boot up.
I couldn't access my recovery anymore, nothing. Edit: I can access my recovery right now, and I tried this, but when I boot up I get the Security Error again.
The big problem right now is the Security Error! How do I bypass that?
So can someone please help me out!
Several phones/tablets of mine bricked and I always found a way to get out of it, but not this time, unfortunately...

Yes, I actually have. Didn't mention it, but after I did that I booted and got an LG logo and below it was a text that said 'Security Error' After like 5 seconds the security error goes away and my phone shuts down. I can only enter download mode right now.
I'll edit my first post with this info.
Thanks for the help though!
Edit: I find a way to access my recovery again because at first I couldn't but I figured out that the code in the thread you linked was a bit different than the code I entered at first.
So I used the code you gave me, but now I get the Security Error again!

Hi mate, just like you i downloaded that damn OTA today and messed up my phone, but in my case was because i had totally forgotten it was rooted and had custom recovery installed :silly::silly::silly::silly:
I followed this tutorial to fix the boot secure error http://forum.xda-developers.com/showthread.php?t=2582142 and it worked like a charm except for download mode wasn't working at all.
After doing some research i found this post http://forums.androidcentral.com/ge...ricked-lg-g2-stuck-twrp-no-download-mode.html and got download mode (apparently) working again but Windows didn't recognize it at all so i couldn't use it to flash the .kdz stock firmware.
In the end i just flashed a custom aosp rom and got my phone back to life but the download mode issue it's still there and it's bothering me quite a lot.
Any suggestion is welcome.
EDIT: Don't download the recovery from the post, instead look for the latest version (2.7.0.0) because the one posted there (2.6.3.2) might corrupt your partitions

Thanks! But does my internal storage get whiped? Will all my pictures etc. be gone?
And the first thred removes the security error right? And after that I can just boot into recovery mode (I can boot in recovery btw) and flash a new rom? Just wanted to know this so I don't go through all that trouble for nothing
Edit: You know I can enter both download and recovery mode right?

Nope internal SD remains intact, basically what you'll be doing is pushing the right files into the system partitions and yes, in theory you should be able to flash a new rom.
Even if you can boot into recovery you should do it if you're getting that error, and after that you can just push a ROM file to flash (i'll assume you know how to do it) and btw let me know if you decide to flash a stock based rom instead of an aosp like i did.
Good luck with that :good:

Ok, i did follow the steps and it still doesnt boot! What should i try next?

If you installed an update zip it probably wants the stock recovery which you can get in the development thread on this forum. Flash that through fastboot then throw a folder named dload with an update.app in it on your sd card. Phone off hold power vol up and vol down until it brings you to a circle with emui inside. Should run fine after that. If not use the stock recovery to factory reset.
The reason your phone won't boot is because out never encrypted itself.for some reason that means life or death to mate 8 firmware

when you start the flash.all.bat and you see the unbrick message your phone should be busy and install the above official firmware and recovery.If not run it again disconnect your phone and connect it again when the unbrick message shows.To me worked fine.You must have your phone in fastboot off course

"Device is corrupt" HELP!

I was just trying to install the 9.0.6 update manually following the instructions in the thread for it here on xda and it wouldn't work. I uninstalled magisk and restored images through magisk manager as the directions stated to do. I couldn't get the update to show in the local upgrade section under system update so decided to reboot to see if that would fix it but now my phone will not boot. It goes to a screen that says my device is corrupt and won't go past that. It says to hit the power button to continue but that just makes it boot back to that screen and if I just wait the phone shuts off.
Any help is appreciated.
(UPDATE) Thanks for the help guys. I got the phone booting again by flashing the 9.0.6 ROM in fastboot. I'm still getting the "device is corrupt" message and have to hit the power button twice to get it to boot so if anyone knows a fix for this I would appreciate it. At least I can use the phone now.

You could try to use msm download tool linked above or flash the full rom again since you can get into fastboot. I'd prob try that before the msm tool though.

Thanks. I got that part and was able to get my phone booting again but I still get the corrupt device message when I start the phone. Wish I knew how to get rid of it. IS there any return to full stock methods that also locked the bootloader and restore all partitions to stock? That is the only thing I can think of that might work.

Someone say that wiping all with stock recovery solved, but device work fine also whit that message, otherwise you can try MSM Download Tool, it will restore all stock to 9.0.5 with locked bootloader.

Use the MSMDownloadTool for the international version, it's the only way to bypass the verity trigger, it will restore the device to full stock as if you never unlocked the bootloader to begin with.

[Help] MLA-L03 No OS, no Backup, Black Screen need help.

I've probably messed this thing up just about as badly as I can.
Here's what I can tell you:
Update: I just figured out that you are supposed to put dload onto a separate sd card, So i'll be trying that when the phone comes out of it's coma XD anything else you can suggest is very welcome.
- The phone currently isn't turning on after messing around in twrp(tried to restart into bootloader)
- While trying to get it working, it is now showing up as CAN-L11(likely from trying some backups of others)
- I was unable to use ANY roms I tried. full update files didn't work. always error 7
- It seems in twrp that I'd often get this error: mountencrypt failed to mount /data, despite wiping /data many times
- I've tried using iso files extracted from some update.app, and using that to get system and data on there, as well as recovery too
- I was switching between twrp and default recovery to transfer files and then use dload to try to recover the system, never let me do it though. got to 5% then told me something like: "Getting package info failed". it would do this in the download and recover mode as well when I would hook up to the internet and it would also give me that error.
You are free to ask me any questions about the device.
I think I just need to drain the battery then I should be able to at least get something out of it, but until then, if anyone has any recommendations after it's functional again let me know. Any help is appreciated.

You haven't flashed the TWRP mentioned in the first post of their thread, hence you've got that error which is basically telling you that you're trying to flash the ROM on an unsupported device (the phone's codename / model is mentioned in TWRP and ROM checks for it), but actually it's working on all models.
- It seems in twrp that I'd often get this error: mountencrypt failed to mount /data, despite wiping /data many times

That occurs because TWRP doesn't support decryption. You have to format data, not wipe. You can format it from TWRP > Wipe > Format data.

Try to unplug the cable from PC. Also, note that I've read in past somewhere that the firmwares from Firmware Finder has to be approved by Huawei and if it isn't, then the stock recovery will fail to flash it. Other Huawei phones has modified / patched stock recovery which allows to flash unapproved firmwares though.

SOLVED:Stuck at PIN input, then reboots

Well, I f*cked up.
Fastboot works, I can flash stock rom via Xiaomi Flash. Flashing completes without any problems. A notification about encypting phone shows up, at 3% it jumps to 100% and resumes boot. Now after each boot, phone freezes at "input your sim pin" and reboots. Over and over again. What can I try, please help :

Try to format data in twrp or stock recovery.
If it does not work flash an android 8.0 or Nougat ROM. Do not lock the bootloader.

Let me guess. From Pie to Oreo or Nougat?

can't unlock OEM, because I can't boot up to developer tools. great, just great. will try to fix that first.

if you can boot to fastboot try to flash stock pie 10.0.4.0 with miflash, after that your device should be able to boot, than unlock OEM and bootloader and downgrade to what version you want

I can get to fastboot yeah, but MiFlash tool says that remote oem unlock is not allowed. So I'll probably have to open it up for EDL. Reboot to edl isn't working. Thanks for the advice tho.

i had a problem like yours, but i have flashed stock rom in non EDL mode and everything had start to work apart LTE band missing that i restored with qualcomm's tools
which stock rom have you try to flash? are you downgrading from oreo? bootloop on android one logo after downgrading is a common issue due to ARB (anti rollback protection)

reward is cancelled from this point on i will reward the one who helped me so far tho. still working on solving the problem so winner has not been decided yet.

you don't understand.
There are no winners and no loosers.
You are free to donate to anyone you want, but your post boost and encourages a bad attitude.
If people start to solve only paid problems, the spirit of the community will be destroyed.

The problem is with the Pie specific partition table
I write the whole guide from memory, so it can differ a bit.... I skipped some steps ( erasing, reboot, fastboot mode, TWRP loading via fastboot, OEM unlock )
From previous writings I think you can know the skipped steps.
Keep in mind: It is dangerous, you can loose your IMEI ( it will only work again with Pie - or there are some writings at forum how can you manually change it. ).
Steps:
1 - Backup with TWRP (fastboot) efs,persist,modem & make copy to your computer and or to your cloud provider.
2 - Create a new folder in Internal Storage -> TWRP -> BACKUP -> With a new date directory ( the backup already made one, make a new folder, with different date )
3 - Download someone's older TWRP backup from xda (I cheated, I copied the following links ) :
(I'm still a new user, so can't directly write url's )
Mediafire : https COLON SLASH SLASH bit.ly SLASH 2QU5NtC
Mirror: Google Drive : https COLON SLASH SLASH bit.ly SLASH 2UN1DTo
4 - Unpack, and copy EFS to the folder created 2 point
5 - Fastboot TWRP -> Restore EFS
6 - Flash the Official latest firmware from en.miui.com ( If you want to make sure go with EDL mode )
7 - Now, the IMEI & Mac addresses are missing. Don't panic! Download update with System Updates.
8 - When you are on Pie again, restore your first TWRP (fastboot) persist partition
9 - One more System restore
At this time, you will have IMEI & Mac addressees, and hopefully a working phone.
Hope this helps. The same thing happened with me 2 weeks ago. This is how I solves it.

Thank you, I solved it yesterday. Hopefully this post will come in handy for other people!
