Hello,
After rooting my p880, my phone hangs at boot. Just after the boot sound (*pling* ) the phone is hanging. The boot image is still moving.
Things I tried already:
I followed this thread http://forum.xda-developers.com/showthread.php?t=2069723, which tells to do a kdz update. This is not working, as I am not able to get to the S/W upgrade screen. Instead, when I start the phone using the power button + volume down, i get the Android system recovery menu (3e).
I tried to upload a new (cyanogenmod) rom using adb sideload, but that didn't work, as the file I used was damaged (I will retry with new file).
I also did a factory reset and a cache wipe.
Can someone tell me what is best to do?
Kind regards

Hi All - while in the process upgrading from the previous version of MIUI to this latest one, I accidentally selected the 'restart system option after formatting the system, cache and data without flushing the new ROM and now the phone won't boot up. It goes to the main Galaxy S screen followed by Galaxy S Glitch screen then it runs some coding (in seconds so i don't know what is says) and then back to main Galaxy screen in a loop.
What I have tried
> Going to recovery mode with vol up + home + power button (released @ first Samsung Screen) but then it goes back to second Galaxy S Glitch screen in the same loop.
> Going to download mode with vol down + home + power button and it does the same as going into recovery mode.
> Tried to do go into recovery and download mode multiple times using different combinations of vol up, vol down, home and power button without success.
> Read through the threads here but I was not able to find anything with the same or similar problem problem
> I tried to follow the help provided by Thyrador on this forum
http://forum.xda-developers.com/showthread.php?t=1109110 with Odin except using the jig method and no go
> Connecting phone to ODIN keeps on going rebooting in the phone in a loop as well.
I know if I can go into recovery mode I will be able to flush the new ROM but getting there is the problem.
I would appreciate your help with this and hope there is a fixable solution.

I have done that a few times and both CWM and download mode should be there.
Make sure everytime you try the 3 buttons you actually remove the battery before trying.
K.
Edit: the coding you are talking about is CWM trying something and that's shy I think it is still there.
Did you just format system?

Thanks for your response
I actually formatted the system, data and cache without flushing the new ROM.
I tried what you said about removing the battery but that didn't show anything on the screen when I tried the 3 buttons. Is that what you meant?
cheers

What I meant was a bit dumb as since you have a bootoop you would have removed the battery anyway each time to try.
I normally flash the same way like you and I always do a factory reset (which formats Data and cache and I do the system manually. Unless soemthing has gone seriously wrong I don't see why you would not be able to get back to recovery?
I have even done it today actually and managed to go back to recovery.
I would say try and boot into download mode. Did you use Download Mode in the past? Are you sure it is there?
I read somewhere else someone saying that it does not always work the first time. Give it a few tries.
Your last option would be the JIG obviously but hopefully you should be able to get it sorted without.
K.
To tell you the truth I always use an app to boot the phone into recovery or download mode however one of my work colleagues has always being able to reboot my phone into any of these modes using the three buttons - not sure how. I will continue to try anyway.
Thanks again for your response and for give me hope that this has happened to you in the past.

I recently installed CM7 after rooting my phone with Superoneclick and installing Clockworkmod. However, after installation of CM7, i managed to boot up the system, played around with it and realised that i needed to install the google addon as well. So i rebooted the phone to enter into CWM recovery, however the problem started.
My phone is now stucked on the LG logo screen and would not change. I left the phone in that state till the battery went dead. Recharged the phone and it remained on that screen.
Tried to connect the phone to the PC to flash it with smartflash, but it doesnt work at all. I removed the battery and held the volume down button while plugging in the usb cable. All i see is the phone stucked on the white LG logo screen.
Is there any way that i can reformat the contents of the phone or is my phone certified?
All help would be much appreciated!
Power up directly to cwm by pressing power button and volume down key at the same time.
Once in cwm, full wipe including /system and reflash cm and gapps.
Good luck.
I have tried that method as well. Sorry. Forgot to mention it in my initial post. It didn't work. I have tried to pull the battery, hold down the volume down and power button for at least 20 times now. Each time i get the same screen. The CWM menu does not come up.
Any other ways?

Hmm.....if u can't power to cwm directly then perhaps try smartflash to any stock rom.
1. Download any stock rom
2. Start smartflash app from pc
3. In power off mode, just press volume down to boot to software update screen. Start smartflash stock rom.
4. Boot up stock rom
5. Install rom manager and flash cwm from rom manager. (Or download cwm from Rusty! Cwm thread)
6. Boot to recovery
7. Flash cm rom
8. Flash gapps
Remove battery, hold both vol buttons and plug in USB. Screen should stay blank, but Windows will pick up an APX device. Now NVFlash back to stock and start again.
yup, tried the exact method that you suggested too. But it doesnt work. Still gets stuck at the LG logo.

This method worked! But i have another problem, windows found an APX device, tried to install it but failed. It says driver was not found. Do i have to install a specific driver for this to work? Thanks!
Yes, good point: http://android.modaco.com/topic/335...k-rom-release-v10b-dated-1300166062-15032011/
I have managed to flash the phone and it is back working now. Thank you so much for your help rusty and temasek!
Hi, first post, hope the thread is not too old.
Unfortunately this is my best chance.
I have the same problem on my O1:
Updated from mik's beta 6.5.7 to beta 6.5.8 with the clockwork manager, at the reboot, I was stuck on lg logo.
Unfortunately usb + both volume buttons didn't work.
It remains still at the lg logo.
Pressing home + both volume, it repeately reboots.
In every case I can't go in recovery mode, so I can't wipe the system folder.
Any help will be appreciated,
thank for your time!
PS: sorry, maybe thread in p500, cm7 will be more appropriate.
hold power button + volume down button for 5-10 seconds may work, phone will reboot into recovery mode, then you are able to flash a stock rom or restore your nandroid-backup (if you made one)
good luck, hope it helps you
thanks, I saw a useful post here:

Then I proceded as you wrote.
Now I'm stuck at adroid logo, without the chance to wipe cache.
The recovery does not start: loading bar and then forced reboot...
I don't know what to do
nvflash
maybe you try this link
android.modaco.com/topic/335416-nvflash-setup-instructions-drivers-links-active/
Sorry, i don't get the link working, copy it in your browser, then it should work (i'm posting with my phone that's why the link is'nt correct, but it works with browser, i tried it out)
If the link doesnt work, search 'nvflash lg p990 instructions' with google, you'll see the modaco website with the instructions and the download links

Thank you. A few hours ago, I managed to make it working.
Thanks for your answers, I appreciated.
nvflash is the way to go. Always make sure to use the usb ports on your motherboard (back of your computer) and not some usb hub or so.
Had a black screen for 8 hours, not able to boot, flash, recover or anything.
Changed usb port and I was able to flash the phone again.
I Have a similar problem as posted by someone else - but I can't reply in that thread yet so here it is:
Also SGS GT-I9000 - now stuck on white logo screen.
What I have done:
- phone was slow and very laggy so I wanted to install new ROM
- found out that 3bc didn't work so tried to fix that using a guide from SamsungGalaxySforums based on one from XDA (tried to post the link, but forum rules won't let me).
- now download mode works but recovery mode still doesn't.
- when rebooting without being attached to laptop it showed funny coloured lines first
- I tried this whole thing again and now my phone is stuck on white logo screen. Still able to get into download mode and flash, but no booting phone.
Any ideas? Should I flash a different bootloader?
EDIT: I had tried the Aries_P-SBL.tar.md5 bootloader and only got coloured lines.
Now using the EZboot-GingerBread-1.0.tar.md5 bootloader and getting a bootloader screen. Now making a backup of all my data first.
EDIT: After backup still hangs at white Galaxy S screen - so still no working phone! Ideas?
Turn off your phone and reboot into the recovery mode by pressing Volume UP+ Home + Power.
Then when in the recovery, select Wipe Data and Cache. Reboot when done. You should be up and running. Also, first boot may take a while so be patient.

It says in his post, recovery wont work, only download.
Sounds to me he has screwed up the bootloader.
Now you've done this http://forum.xda-developers.com/showthread.php?t=1089989
I now suggest you boot to download and flash a stock rom using ODIN.
just flash stock Rom using Odin and than you can flash what you want
was with the original rom lg. and then went instalr the recovery of the cyanogen rom manager app, and then hung up the phone and now the message appears in red at the top of the screen
"Critical Failure: Unable to start Kernel.
Unrecoverable bootloader error (0x00000002)"
and I can not get into download mode to install the original rom again.
and now what do I do? I lost my phone?
you flashed cwm without unlocking your bootloader. re-flash latest jellybean kdz file for your phone using http://forum.xda-developers.com/showthread.php?t=2069723, then read some more about unlocking bootloader, and then start again.

but now I am unable to get into download mode on the phone. is
" Now just hold down vol - key ( hold hold hold dont release !!!! ) and plug the USB cable until you get screen like this :-"
he does not. whenever I do this it only vibrates strong and goes to the screen with the error message. I do not know why that. remember one time it happened to me already but can not remember how I resolved it is possible to even lose the download mode?
Its not possible afaik. Are you sure you are holding only vol - key and plugging in? Dont hold power key!
yes, I'm almost the whole day trying to get into download mode by pressing volume down + connecting the usb. and whenever it vibrates strong and hangs on lg logo. tried to volume up + usb connect. and no download mode. I'm going crazy with this phone. otherwise hesitate to hard reset? or other shortcut to download mode?

hard reset wont help you, as far as i know, you somehow need to enter s/w upgrade screen. did you try it with battery out?
he battery of the same error, and no battery it does nothing, or vibrate, or flash screen, nothing happens
Will I not be able to see my optimus running again? :crying:
it is not possible to load the kernel, what could I do?

Hi Raphael20 and everyone else,
Did you manage to figure out a solution to this? I have the same issue, i.e. cannot start my phone by holding the power button. Not even when people suggest to get to the S/W Update screen by holding the Volume down + plug into the computer.
I got to this error when I tried to do a factory reset. I installed the ClockworkMod Recovery. Then the factory reset via Volume up + Power button gave me the "Critical Failure: Unable to start Kernel" error. I somehow managed to get access to my phone by holding the Volume down + plug into the computer. Then tried to do a factory reset via the system settings of my phone. My phone restarted and then gave me the "Critical Failure: Unable to start Kernel" screen of death! Now Volume down + plug into the computer gives me the "Critical Failure: Unable to start Kernel", no matter whether I have restarted my computer and I have tried another computer. It seems that the bootloader is wrecked.
Does anyone have any suggestions?
Thanks!
hi everyone,
I was runnning a cm11 nightly rom but after and update from cyamogen i lost baseband and imei. i looked up some methods to fix the problem so i tried to go through the steps and downloaded the stock rom and tried to flash it using LGflash Tool and Software update Kdz but both options failed. I also tried the lg flash tool 2014 version, which got the farthest, but also failed. The just gets stuck on READY and the KDZ method gets stuck on line 207. The 2014 version of the flash tool strarts the upgrade but then a message comes up saying "there is not enough memory in the phone".
The problem is that now the phone is stuck in software upgrade mode and it doesn't even go into recovery mode ( i had CWM installed).
what should i do?
SOme help would be greatly appreciated,
thanks.
Just try to press and hold [vol -] and [power] until you got the android recovery figure and wait until they reboot again. If is again something wrong then try again to flash KDZ...

if i keep the vol - and power pressed nothing happens, it just stays in s/w upgrade mode. I've tried kdz and flash tools many times but still stuck on the same screen.
