[Help] D802 4.4.2->TWRP 3.0.2->CM13->BRICK! - G2 Q&A, Help & Troubleshooting

Prerequisites: D802, 32 GB, Stock 4.4.2. I believe "Int" version (original motherboard was replaced)
I tried to upgrade stock 4.4.2 with CM13 and failed with the brick result (LG logo for a couple of seconds and the black screen then).
Now the recovery mode is available (TWRP 3.0.2 bump blastagator) but there is no android image loaded except CM 13.0 snapshot 20160418 which causes the brick state.
The questions are following:
What was wrong?
What proper android image can be used to unbrick?
How to load image on the phone?
Since I found Mount->USB-OTG checkbox in the TWRP, then I hope the OTG cable can be used to load image from USB flash drive. Unfortunately I can check it now.
Will be appreciate for the help.

KK bootloader, that's the reason. If you want to have stock bootstack you need to update to 5.0.2 stock, root and then flash TWRP and CM13. Everything'll work fine.

Thanks edi.
Do I need to replace TWRP bootloader with another one (I guess stock) and then update to 5.0.2 or I can start updating 5.0.2 with TWRP?

If you want to stay with stock bootstack:
You need to flash 5.0.2 KDZ file with download mode.
If you want to do it fast:
You need to flash hybrid bootstack.

Thanks a lot.
Fixed.

[Q] Got a used D800..

Should I flash the latest KK image to ensure the modem and bootloader are latest version..
The baseband says: M8974A-AAAANAZM-1.0.190082
I received it with 2.7.0.0 twrp and there were custom rom zips all over.. so I can not tell when it was rooted..
Open to suggestions..
Hey mystique
If you want to start with a clean slate I recommend getting your stock image from here
And use the lg flashtool in the back to stock guide to flash it.
Incidently, since your on twrp 2.7 I assume that you're on the jb boot loader
What was that "phone info tool" to find the bootloader version..
Looks like the device was initially rooted in July 2014..
Assuming that they had kk and such..

Well did you keep ANY KIND FORM OF BACK UP TO RESTORE BEFORE GOING TO LOLLIPOP?
If not,
1. Returning to stock will bring you back to Stock KitKat ROM.
2. Back up your data and pictures to the cloud or Hard Drive.
3. Download your .kdz file using your IMEI from www.lg-firmware-rom.com
4. Like @raulx222 said, Return to Stock Firmware.
5. CREATE A NANDROID BACKUP.
6. Install your desired custom KitKat ROM.
Give more info please. When you flashed lollipop, which ROM you flashed? you flashed other files too?
Anyway, flashing the stock firmware is almost any time a way to solve the issues ..You could backup your files from TWRP via MTP and then flash the stock firmware. You also can backup your files with TWRP using a usb flash stick and a OTG cable.
restore to kitkat
Hello just flash this attached file in recovery. After that flash jb bootloader for d802 and baseband and recovery you use for roms you use. Everything will work
Btw the zip contains stock kk 20H partitions you need to restore. Simplerom to work on lollipop modify this partiton on your device to be as f320 model in some areas to get lollipop booting
Tell me did you make it boot

How to revert back to the stock firmware?

Hi All,
A couple of days back, I installed custom ROM (Recreated Remix Leopard) successfully on Zenfone 5. I was on the stock lollipop 3.24.40.87 firmware before that. I rooted, unlocked Bootloader and installed TWRP recovery on the stock ROM and I also took a nandroid backup. After using the custom ROM, I decided to go back to the stock ROM. I used the nandroid backup for restoring and got the stock ROM. But, now I want to go back to the stock Kitkat ROM (as the lollipop sucks) and I also don't want the custom recovery or anything. In short, I want to revert my phone to the real factory condition.
I tried to go back to Kitkat by the ASUS official method. But that didn't work. Then I tried to re-lock the Bootloader with the tool from which I unlocked it. But when I did that, I got stuck on the USB logo screen. So, I unlocked it again with the same tool and the phone starts normally. So, how do I get back now?
What would happen if I flash the stock ROM via TWRP? Will it remove the custom recovery and lock the Bootloader?
I read a couple of articles, a few of them suggested to install the stock ROM with the official ASUS method (copy the files in internal storage and the phone will notify to install the update). The article even says that by this method any custom modifications (recovery, root, Bootloader) will be deleted. Is it true or will this work?
Thanks in advance!

Link rom WW 3.24.40.87 modded, flash via TWRP: drive.google.com/open?id=0B7Py5ad2aHwKMHRsZ1NJM0tfLTQ
If you flash this rom, it will not remove the custom recovery + lock the Bootloader
If you having a problem while flashing this rom, you need to flash stock recovery 2.22.40.54, after that you can sideload stock rom via ADB
Sorry for my bad english ^^

Hi, thank you for the reply
You said WW 3.24.40.87 modded, do you mean that this rom is not the official one? Does it improves the battery life and other bugs of the stock rom?
I really appreciate your help!
You cannot flash stock rom via TWRP!
This is modded rom, so you can flash it via TWRP easily....
It's Official rom from Asus, just modded to be able flash through TWRP

Thank you for the info
But the thing is that I am already on the stock 3.24.40.87 rom and I want to go back to Kitkat 2.22.40.54 because it has much more improved battery performance than the lollipop. Is there any modded version of the stock Kitkat rom too? Or how do I go back to it?

you were on kit kat and flashed a stock based LP rom ? not sure but didnt you have to be on stock LP then flash cloudy.
maybe flash a KDZ theres flasjable ones as zip for LP.
what i done from kitkat is
root/autorec. update twrp 2.8.7.3/bootstacks 5.02. bumped KK. you know you must reboot recovery into recovery again from recovery to take effect. during update of twrp and bootsacks then flash LP KDZ stock. then just wipe and flash cloudy.
Cheers managed to flash cloudy g2.2 over it,
Gps is terrible though

Always get bricked after installing lollipop

Hello, today I decided to install Google Edition 1.4 rom, just after flashing I bricked my G2, and my PC detected a lot of partitions. I fixed that, flashed stock KDZ with LG Flash Tool, started again. And its the same result. Then after installing stock rom, I tried to install another Lollipop rom (Cloudy G2 3.3) and again PC detected only a lot of partitions.
Sorry for pure English.
