First, I rooted the device, then I flashed CWM recovery. Then, I don't know why i decided to update my phone with OTA update from v10A to v10B.
During the update, phone rebooted to CWM. From that point every 'reboot now' brought me to recovery (Recovery bootloop). Then I used KDZ Updater to flash stock kdz, but it only made it worse. I have tried every version of KDZ, with every possible settings, now there is only emergency mode, no matter which button you press to boot it. KDZ Updater always crashes, at various points. HEELP!

So I accepted the 4.4.2 OTA update this morning and now I can't get my phone out of recovery mode. It's a Sprint LG G2 that I rooted using the ioroot method. For backup, I used Clockwork Recovery Mod and now when I try to reboot the system, I get the message "ROM may flash stock recovery on boot. Fix? THIS CANNOT BE UNDONE." The options are No and Yes - Disable recovery flash. I've tried both of these and it just turns the phone off. Any ideas on how to fix this?
Hi.
I have a Vodafone Germany LG G2 with stock KitKat.
My story:
I installed root and recovery. Then I tried to install the OTA, doesnt work, tried it with LG PC Suite. Boot certification verify error.
Recovered all with this guide:
[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2
http://forum.xda-developers.com/showthread.php?t=2582142
Then flashed an open LG G2 kdz and all was fine again, but...
no Update for me with knock code.
----------------->>>>
So i tried to flash the original Vodafone KDZ in Offline mode. I get an error at 15 percent and it wont work. So i restarted my phone, but i only had a black screen. Nothing worked again (no download, no recovery). Ok, plugged in in PC and woha, broadcom device detected. Back to ubuntu and recovery again (see above).
After that, i restarted my phone, but no recovery was there... only the lg logo. Everytime. Again: No Download, no recovery. Stuck at bootloop every time. Factory hard reset can be called, but if i confirm, "Factory reset processing" appears, now for ~30 minutes. Is there a way to fastboot or to another state than that?
Any idea?
Hi,
First of all i committed a mistake of thinking that with TWRP aboot + stock Recovery i will be able to do OTA upgrade, which made my phone not booting, undetectable by computer and majorly not getting the LG Flash download mode by pressing any combination of keys., Stucks at LG logo.
Device: LG-G2(F320L)
KDZ stock: F320L21V_00.kdz
1. Flashed this kdz using LG Flash Tool 2014.
2. Flashed from F320L_AutoRec.apk, the images only aboot, and recovery.
3. From DorimanX project generated the boot.img with StockROM(F320L21V_00.kdz) version bootimage RAMDISK.
Everything was fine., till then.
After that, i got the OTA pop up., So, thought of installing OTA. As I had already faced the TWRP bootloop once and in some post i remember i read flashing OTA needs stock recovery image. Here is the place I commited the mistake. So, signed the stock recovery with aboot of TWRP using loki_flash. Accepted OTA. Thats it.
From then, no booting, no recovery, no adb, no fastboot, and unfortunately NO LG DOWNLOAD MODE also it goes.
When i try to go TWRP, it stucks up after the initial TWP message.
And pressing some key combination, the device goes to LG service mode, and showing the IMEI and some list of 3 options in korean which i dont understand. By pressing any of the option device reboots and stucks with LG logo.
Even my device is not shown up in the ubuntu, when i checked "dmesg".
Can anyone help to get the device into Either download mode or fixing the boot.
Sir,
Please wait until mods will move this thread to the device specific forum.
Stand by
Good luck
No solution yet?
The phone is still in the same state. Can anyone please suggest the solution to make the device working? Thanks in advance.
So, I did brick my D802 in some way.
After a long history from cloudy g2-g3, rr, cm12, cm13, lineage 14.1, I clicked by mistake on the OTA of the lineage.
I thought I could stop the update once in the recovery, but I got stucked in the recovery bootloop. I got rid of it via recovery terminal, but system didn't boot. I tried reflashing lineage, nothing happened, I tried restoring a cm13 full backup, nothing happened, so I got back in download mode to restock with lollipop kdz (the one I used every time I restocked to change rom). It did not work, and I had to download a different KDZ to get to stock again.
Now, all the methods always used to root + recovery didn't work, so I manually rooted, installed the proper AUTOREC, but it didn't work (as I understand after hours of searching because supersu had updated himself in the meantime).
So I tried to install the TWRP image using flashify, it didn't work and corrupted something in my recovery. So i tried to unroot everything and reinstall the original root + supersu without letting him autoupdate. Not working.
Well, now I can boot and I can get in original lollipop rom, but I have no recovery and download mode appears but doesn't work anymore (once I had 3 COM ports when connected in download mode, now I can see only one; kdz flash does not sense the phone connected). When I try to open recovery I got the error "boot certification verify, secureboot error" in the top left corner of the screen, then a white page opens with the message "critical error" "demigod crash handler", volume up to download mode (that opens but does not work), volume down to reboot.
Now, I am stucked, I cannot find any suggestion of what to do to get the recovery working or to get the download mode working again.
Any help will be highly appreciated.
Thank you very much guys.
Not sure will it help but you may give it a try:

Hello there.
I unlocked the BL yesterday and flashed TWRP and then AEX latest Oreo based ROM. It was fine, but since I came from Oreo, I did not have fingerprint sensor working.
So I wanted to go back to Nougat and then flash the AEX from there. Uppercut didn't recognize the phone so I installed a stock based rooted Oreo from TWRP.
I started the Uppercut flash with a stock Nougat system, but it was interrupted (in upgrade mode, refurbish mode doesn't work at all) referring to: error 0x2bc invalid command response code.
Later with another kdz file it gave me: error 0x2bc crc checksum error
From then on I cannot get into anything else, just download mode (in there, wildly short-pressing the Vol- and Power buttons gets me into a menu where I can turn the phone off, and I can boot into Fastboot mode. )
In fastboot mode I flash twrp and then when I try to boot into twrp by selecting the usual reset system options, it just gets into download mode again.
I could not get any kdz to install on it so far. I tried H87020C, 10D, 20A.
So now I have download mode, which fails and fastboot mode, in which I don't really know what can I do.
LG Bridge doesn't help, LG Flash Tool stops at extracting all the kdz files I gave it and LG UP also doesn't work.
The bootloader is still unlocked.
Please help me with this.
All of a sudden for the fifth trial, LG Bridge somehow succeeded to install and boot the phone via Update Recovery Error method.
