[Q] LG D802 CWM bootloop.. Please Help - G2 Q&A, Help & Troubleshooting

Hi,
I have internation variant of G2, D802.
I rooted and installed CWM but did not flash any ROM.. use stock itself.
Then suddenly did OTA and stuck in CWM bootloop.
SAW the thread for TWRP bootloop and i was not able to get adb working..
finally, i formatted all partitions shown in CWM advanced menu, then adb started working in PC.. when i start adb in command prompt, it showed my device as recovery. then i pushed omni rom and flashed it.. again my phone went to cwm bootloop.
Can someone please please help on this? i am stuck for past 2 weeks...

Hi.. U are not the only 1, having problems after trying OTA.. But I assume u can go into download mode cuz u can access CWM..
So I would recommend u to try this solution http://forum.xda-developers.com/showthread.php?p=45293512

if I remember correctly that means your recovery did not flash correctly so I recommend using either flashify or freegee from playstore and retrying
It is actually the stock recovery. Try again flashing TWRP or CWM

ok there is a guide here somewhere which explains that if you were trying to install recovery and then go stcuck in fastboot mode you have to get the stock recovery back let mee if I can find the guide and i'll report back
re-edit: try this thread http://forum.xda-developers.com/showthread.php?t=2477595 also you can find needed files here http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware make sure you download correct files for your firmware

Thanks a lot! I followed that guide, and afterwards I was no longer even able to get into recovery/download mode....so I though I was even worse trouble....since one the the instructions was to erase the LAF file and flash it again with a downloaded LAF image, I decided to go to the link with all the files you provided and flash each of them....rebooted, and the phone was able to get into recovery mode again...Then I pushed the file for my phone ( http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware) using Uptest (R&D Tool), rebooted and the phone worked.

[Q] Flashing back to 4.2.2

Hey guys, Hopefully somebody can help me here.
Basically i flashed & rooted my D802 to 4.4.2 using this method > http://forum.xda-developers.com/showthread.php?t=2680789
All was running fine however somewhere along the line something has messed up! I tried to boot into recovery and now im hit with "Secure Booting Error! Cause : boot certification verify" instead of TWRP!
Ive tried to use this method > http://forum.xda-developers.com/showthread.php?t=2625044 to flash back to stock and unroot BUT when i get to step 5. of method 1. instead of asking to to Select Country & Language it starts the LGMobile Support Tool and the tool tells me i have the latest available software for my device.
The phone is running fine and i can get into download mode.
Thanks in advance for any help.
Anybody got any ideas?

The ROM you flashed is from my thread. I'm not sure why you think custom recovery remains available? Unless I've missed something else you did. It is overwritten by the stock ROM when flashed. Hence I clearly stated that custom recovery will no longer be available.
I don't know what "messed up" with the ROM?
I suggest you revisit the page you used and try the alternative method if you really fell the need to downgrade...
Well after 5 house of messing around i managed to ADB push CM11 too my device, Boot the phone then connect to my PC then re-flash 4.4.2 & root using this method > http://forum.xda-developers.com/showthread.php?t=2680789

rooting and TWRP update problem

hello all.
im using a G2 D800 AT&T, and since i have a tethering problem which i was assured would be fixed if i installed a new ROM.
so i went ahead with a guide for cloudyg3 rom, rooted using towelroot and verified with root checker, all is well.
installed TWRP with freegee- the TWRP version was 2.6.3.3 and i was told i needed to upgrade it to at least 2.7.1.. thats where problems started.
i couldnt for the life of me upgrade it to any version, 2.7.1 or higher, and TWRP showed a loki.sh problem. thought maybe unrooting and starting the process all over would fix it so i deleted all my apps, then unrooted with supersu.
tried to root with towelroot and no go. immediately after trying to root, root chekcer gave me a "device is not rooted" answer (before there was no problem), and the device reboots just after im trying to remove towelroot from the task manager (center button).
did i mess up my phone so it cant root? is there a way to check that\ other root methods?
please help
Try other methods like ioroot and if still not working flash a new kdz via download mode and reroot with some method. And btw you can easily update twrp by flashing just a zip but don't forget to restart the recovery after flashing and restore defaults under setting. And next time try autorec

first, thanks for your help.
second, i got the device rooted and all, installed TWRP through freegee and downloaded newer version (2.7.1),
and when i booted the device into TWRP mode and tried updating to 2.7.1. , THE SAME THING HAPPEND AS BEFORE-
i just cant update the twrp to more than 2.6.3.3., no matter what version i try (2.7.1 or higher).
getting error message of: assert failed: run_program (temp\loki.sh)
error executing updater binary in zip \sdcard
error flasing zip \sdcard\download\...
updating partition details.
and getting two options: wipe chache\ dalvik, and reboot system.
this happend to me with EVERY TWRP UPDATE I TRY...
and from my understanding i must update twrp to more than 2.6.3.3 before trying to flash new roms.
thats the problem i had before as well, device simply wouldnt update to more than 2.6.3.3
thanks...
I rooted with towelroot then used AutoRec (link) to install TWRP on mine then updated to 2.8.3.1 from blastagator (link) via the older TWRP I installed.
WTF...PROBLEM
i installed autorec, clicked okay and got into the twrp boot recovery mode again, and tried to instal new version with same failed result (pictures added).
but then, i clicked on reboot, device rebooted, BUT DIDNT BOOT BACK TO NORMAL SCREEN.
now the screen is black with a green\blue led that keeps flashing and wont stop.
computer recognizes the device when connected with a USB.
WTF?

cant do ANYTHING.
screen is black and the led is flashing green and blue nonstop.
tried turning it on or pressing the volume down+power button but nothing (i added a picture). computer wont recognize the phone either.
when i try to call the phone is off
please help
the phone seemed to be in twrp 2.7.0 although it showed me a failed result
I'm not very sure but maybe its was something from the freegee app... you should't have any loki error
So your screen its COMPLETELY black?.. even you hold the power button or something it didnt show anything on screen?...at least if you hold the power button the led stops to flash?
UPDATE
so after i did hard factory reset i am in boot recovery mode, with a twrp version of 2.7.0.0
still cant get past the LG logo (LED keeps flashing) but at least i can be in recovery mode.
computer recognizes that the phone is connected with USB but cant get it to appear as MTP
thanks
i read up and i THINK im in a boot loop.
maybe i was really stupid- are you suppose to use autorec only on kitkat devices and nothing else? my device is 4.2.2.
Yea, I'm on the same boat. I was on 10b (4.2.2) tried using freegee. Freegee said it didn't support my device went to auto rec. Auto rec managed to flash trwp made the backup then was told to reboot the phone. Then I got the same black screen with the blue green led. I plugged in he phone to the computer and pressed volume up and the power button and I got the hard reset option. I confirmed the hard and now I have rebooted into twrp.
Word of the wise: once in trwp don't restore your backup. It doesn't work. See other thread on this.

Can no longer get into recovery boot

First, thank you for any help!
I did look threw the forums, as best I could... I did see any solutions here that worked for me... saw some one another site.. they did not work.
I can no longer get into ANY recovery boot... Every time I do the buttons, to go into recovery... it show "booting into recovery" blinks, vibrates... and then boots into the phone in normal mode....
I recently had to flash it to stock with Odin.... which lost my root.... I tried to install TWRP , so I could root it... did not work... then used KINGOROOT, to root it, which it claims DID work (the rooting) , after two tries... and then it did allow me to go into "stock recovery" mode...
...so i then flashed TWRP with Odin... and ... now, again, I get not get ANY recovery mode to come up.
ARGH!!!!!!!
Please help??

I am flashing TWRP 2.8.7.0 which is the SAME file I used when I flashed it... a year ago?
I know that there is a new version of TWRP... but I have heard there are problems with the newer TWRP flashing ROM's....
On another site, someone said that the problem was that if you flash back to stock, the new (stock) bootloader has a line it it, to check that you can only use stock recovery file... ... >sigh<....
My "simple" project... to upgrade my phone... has become a night mare.....
2.8.7.0-hltetmo?
If it doesn't work, try cwm.
Sent from my SM-N920C
Got it fixed!!
Figured I would say how, in case someone else has the same problem.
I had already rooted the phone with "Kingoroot" , when I was trying to put TWRP on...
By downloading and running "TWRP MANAGER" from the play store, it was able to install it on my phone, and I am now able to boot into recovery.
Good luck!!
