[Q] [20a] stuck in cwm bootloop after installing 20b update

Hi,
i am stuck in a bootloop.
i have an unlocked bootloader and had CM10.1 previously.
i then went back to an old 20a backup i made some month ago.
that worked fine.
my phone downloaded an update to 20b then, and i installed it.
after that i am stuck in a bootloop now. normal booting gives me cwm.
i am not able to turn the phone off and charge it, as mentioned somewhere else, to clear the "boot to recovery" flag.
someone knows a way to clear this flag?
Its not important for me if i run stock or CM, but even when i install my CM backup now it still boots into recovery.
holding <down> while rebooting gives me "S/W Upgrade - Please wait while upgrading".
it seems the 20b update is still present and trying to boot into stock recovery, resulting in cwm getting loaded everytime.
(cwm works fine, i can upload a zip and execute it)
greetings

i had the same, if you want to install ota updates you should have the "original" recovery.
i flashed it back to stock with LG .kdz flasher. if i remember correct flashing a backup from sd card won't slove this problem.

hm, i remember having the same problem while installing CM. there was something i did to interrupt the loop, and yes, i think the original LG suite or kdz was involved. but i should not need to reflash the original rom.. its just a flag, i should be able to clear it with sideload/zip/button combination.
[edit] maybe i wasnt clear about that: i dont need the 20b upgrade, i would love to cancel the update process, if that makes my phone boot again.

sorry but i can't help you with the flag... i solved it by reflashing but i have to admit it's quite drastic.

well..
i will reflash stock i guess.
do you remember which thread/tool/drivers you used to reflash?
i am on win7 and my PC isnt able to load fastboot nor LG mobile usb drivers.
i have them installed but get the yellow warning on both in windows hardware administration page

Easiest way to reflash stock is to force an update using the LGMobile Support Tool. Once your phone is connected (I suggest the S/W Update mode) look for the option somewhere in the upper right menu.
Edit: This will also revert to the stock recovery.

if i recall correctly, the LGMobile Support Tool tool wont recognize my phone, since i have a custom kernel, unlocked bootloader and a custom ROM.
i am trying to flash stock ROM now with kdz updater ( http://forum.xda-developers.com/showthread.php?t=2069723 ), and if this does not work i am going through every method thats there..
total overkill for a working phone thats just too stupid to boot the right option..
@moneyvirus: thx

Not sure about this, but the S/W mode might make a difference here. No harm in trying, right?

well. i was able to install stock 20a with kdz updater and link above.
cwm is gone now ofc, but everything at least works.
in some hours i will be rooted and cwm'ed again, but well... its always the same lesson: never touch a running system.
but maybe here's the wrong place to insist on this wisdom

Stuck in bootloop

So I was working on flashing this rom http://forum.xda-developers.com/showthread.php?t=2715408 and I got so far as using the tools in this http://forum.xda-developers.com/showthread.php?t=2713954 to one click root and install twrp, made my nandroid back up, copied that to my computer, then flashed the 24a bootstack zip from xdabbeb's rom thread. the bootstack flash failed and now I do not know what to do next...its stuck in a bootloop at the lg logo.

I am able to get into the recovery and download mode if that helps.

please help!
Here is a bit more information about my situation:
Hi all,
Started by rooting with the one click method, then installed twrp via one click and moved the 4 zip files from this rom thread http://forum.xda-developers.com/showthread.php?t=2715408 to my phone in preparation for flashing the new custom rom.
went to flash the 24abootstack.zip via twrp, that failed, so i tried to do the a recovery via twrp, and that did nothing.
after that i found out i was able to get into download mode still
the phone doesn't show up correctly in device manager which means I cannot makee sure it is on com port 41 before trying to use the lg flash tool to flash the tot file.
The phone shows up in the category 'Andorid Phone' and its called 'USB Modem Phone ADB port in the device manager.
I have deleted all the drivers and re installed them also.
Im going on a week and a half without my phone and i really need it back!!

Does anyone have any suggestions as to what to do?

Whoever can get my phone up and going will receive a generous donation via paypal. There is just no way I can go another week without a phone!
If we need to use linux to fix this, I have Ubuntu 13.04 ready to go via bootable usb also.

recovery and download mode

I would do that, but like I said I cannot get the phone to show up correctly in device manager which means that I cannot make sure it is on COM PORT 41.

A big thank you goes out to bouchigo for helping me get my phone working again. All I had to do was adb sideload a new bootstack zip and rom zip and I was up and running.

I suggest this: http://forum.xda-developers.com/showthread.php?t=2432476
The guide you are currently using is old, and links older .tot files (the guide even suggests the .kdz method if you are having issues). I suggest the .kdz method, it's quicker, and less setup than the .tot method.
I also suggest you use twrp recovery, and install Roms that way, rather than using the clockwork mod app.

Can you direct me to a thread with the current kdz method? Thanks for your help.

Phone restarts every minute, cannot enter recovery mode, Please help!

As I said, phone is restarting every minute, it cannot enter recovery mode by using 3 buttons. I've tried hard resetting, but whenever I press the button to erase it, it either does nothing or it restarts again. Also whenever I change some of the settings they revert after a restart. I've tried flashing some rooted roms with odin, and it said "pass" but phone still remained the same. I've tried flashing pit files, the three button recovery and all, but still nothing did any good... Is there any way I can fix this? Is there any way to find stock official images and install them without odin, like LG's software update kdz, or HTC official installer files? Is the phone just dead? Please help guys!

Well, I forgot to add, it is my friends phone which I am trying to repair, thing is she said she tried flashing official firmware from sammobile, but it didn't work... Which options should be checked while flashing it? Maybe she didn't put it right...

Well from what I see, it seems she checked right options. What could possibly go wrong with it? After Odin was done, the phone was exactly the same as before...

If odin fails try unchecking the reboot option and flash again.

Okay, I will try that! Will tell you the results later... By the way, is there any way to flash the zip via adb? I thought of wiping the phone through adb first.

Try to install twrp from novafusion by odin without checked 'restart phone'. Then pool out battery, put inside and go to recovery mode. Choose wipe, advanced wipe, choose everything without SdCard and slide button. Next turn off phone.
After this turn on download mode and install stock rom by odin.
If it not help, you have bricked phone.
Try any method but i dont know why you do something with pit file. Its not recommended to do wth this if its not necesary.
Cheers!

I don't think pit file thing did anything because phone just reverted back. By the way phone is running stock it isn't rooted. Shouldn't it be rooted for custom recoveries?

Answered on your question, yes. Because you need full access to operations on your phone. Btw, when you instal twrp and in some part of this recovery you want leave and restart, twrp ask you, did you want root your rom (its clue).
The easiest way to root your stock rom, find thread with prerooted stock rom to install by odin. Its the easiest way.

Download Mode not Working

So I've tried the H811 one click and does work and so I wanted to flash a rooted stock rom via download mode. I did it step by step and it's just not working, I've waited 20 minutes for each time to see if it would work. Typed LEAVE and nothing still. What is wrong with this thing? Also with the H8111 one click the recovery deleted my stock recovery I don't even have that anymore.

So you managed to install twrp and you want to root now? You can download the desired ROM zip and flash it from recovery. No download mode needed if you have twrp.

No, I didn't have a custom recovery. I tried that, didn't work so I was just going to try and get root. I checked drivers, multiple USB cables and ports and nothing. I did it on my friends computer and I was able to get root and TWRP on. I'm using official CM 12.1 now and it works great. I figured it was probably just a USB/Cable/Driver issue but I had tried so many thing other than a different computer.
