[Q] Optimus One/T (CM9) won't boot past LG logo - Optimus One, P500, V General

Backstory: In October, I ordered my LG Optimus T from T-Mobile refurbished. Shortly afterward, I rooted it, flashed CWM and then installed void. #forever. After Google announced ICS, I did some research but couldn't find any CM9/ICS ROMs for P50*. I kept searching and eventually found Lupohirp's, which I flashed and used for a while. This eventually morphed into Hephappy's CM9, which I have used until about 3 days ago. His ROM reached its final version recently. I tried flashing it, but ran into a bit of a problem.
My problem: From inside the CWM app, I initiated a backup, like I always do before flashing. The phone shut down and started booting but never made it past the LG logo. After about 10 minutes, I got impatient and pulled the battery. I was planning on trying the backup again. However, I have not been able to get it to boot past the LG logo. If I have it plugged in, it will just sit at the LG logo forever (I tried leaving it this way for over 36 hours, but nothing happened). If I don't plug it in, it will turn on to the LG logo but turn off a few seconds later. I can then start it again but it stays on for shorter. I can do it again for even shorter, and so forth until it won't turn on at all. I have tried booting, both plugged in and unplugged, with every imaginable combination of buttons, cards, and having the battery in or out that I can think of and it still won't work. I can get it to boot into emergency mode (under the same conditions as regular boots), but that's for the most part useless to me. I have a feeling I could restore it to stock using KDZ but it seems like it would be a lot of work rerooting, then reflashing, then trying to recreate all of my data. My hope is that someone out there in XDAland has an idea on how to fix this.
Thanks in advance!

I know how to put my phone into recovery but it won't get past the LG logo, no matter what I try. I've tried Vol Up or Down + any of the 4 buttons + Power and still nothing.
Thanks anyway

if the problem is on the phone boot you have to do the following en enters recovery after format boot and mount and format system. CM9 install the rom again. when you finish the installation of the rom does reboot and enjoy.

I don't mean to sound stupid (but I probably will anyway), but how would I format it? Also, will I lose everything?
Thanks

lol
lol the point is he cant enter recovery
i have a lg p509 but i have none of those problems...
try using kdz and reflashing original 2.2 then reflashing cwm on
remember to backup ur sd card
if you get to recovery
go to mounts then you will see format system 3rd to last
im using cwm touch recovery

do as I am saying that you will not miss anything. makes only format boot and system format. You can be assured that not lose anything you have on your phone.

loads while in power key and volume down key home keeps the keys pressed until the menu.

What was that supposed to do?

recovery
once if you get into recovery then you can mount usb to a computer copy ur sd card contents make a backup etc
then you can format anything without any risk'
one warning. once you format boot do not reboot until you flash another boot img or ur phone might be bricked forever

if we do not have root on your phone uses the superoneclick. you enter emergency mode that recognizes the pc.

But how do I get into recovery mode?

Power / vol. down and home. is always the pressure until you see the recovery menu.
Sent from my LG-P500 using xda premium

60 seconds with all 3 pressed, still just the LG logo

do so press power and vol down for 10 seconds

start up goes to black screen, no recovery

My buddies phone just starts up to a black screen after the galaxy S boot screen. I've tried getting into recovery but it does not work. This phone was completely stock, so I'm assuming it was on 2.1 eclair. I tried odining back to stock but thats not working either, also the only way i was able to get it into download mode was by doing the method explained for HWL phones. I cant even get adb to recognize the phone cuz i can't turn on debugging, anyone have any ideas?
Use odin v1.3 . With the cable pluged into the computer and the phone off plug the usb into the phone while holding both volume buttons . That should get you into dl mode . Just flash back to stock .
Sent from my SGH-T959 using XDA App
That's what I did still not working, the phone was stock yo begin with, that's why I'm so confused, any way to wipe the phone? Our does using odin quotes the phone already? I tried adb but since the phone is not booting up all the way its not being recognized by the computer

Do it again and click repartition . But it important you use v1.3

What exactly happened to make the phone that way?
Sent from my SGH-T959 using XDA App
no idea, he said things started force closing all of a sudden, then it stopped booting up properly... he said he didnt root or anything, so the phone was completely stock...
and yeah i used both the pit and tar files

To acess recovery)(if u habe it) shut down o1 and after that press this 3 keys: menu + vol down + power ....after the lg zcreen appears release power button but keep presses the other two,and then u will go into recovwry(if u have it) from here u will install reco ery or flash a new rom.
If u don' t have custom recovery but still cam acces emergency u can try to use Kdz software to flash your oroginal firmware back.there is thread about doing this here.search "how to flash original firmware p500".i think The_error has a thread about this.also u can try to search" phone not responding, last chance to repair".
Sent from my LG-P500 using XDA App
what u mean by if you have it ? as in the recovery.
OK..You need to access recovery via 3 key combo:Shutdown the phone, then pres the Menu key+Volume down key+Power button.When The phone started release power button , but keep pressed the other 2, and then you will enter the recovery.Is it clear until now?After you have entered the recovery go to backup/restore and select restore( if u have made a backup in the first place) if not you must flash a new kernel or a new rom, but don't forget to wipe everything first.

LG P500 Hanging on LG Logo
Hi (my first post),
I tried to change my ROM from 2.2.1 to 2.2 V10G for rooting abilities. I received an error message while the screen was in "Emergency Mode!!" and then KDZ_FW_UPD said "FINISHED". Here are the last few lines from the log:
TYPE_LPARAM_UPGRADE_ERROR_WRITE_TO_FLASH
[21:26:15:103] : WM_COPYDATA ¸Þ½ÃÁö º¸³¿ 3 - Close Port
[21:26:15:103] : Close Port<<

[21:26:15:103] : ¸Þ½ÃÁö º¸³¿ - TYPE_WPARAM_UPGRADE_ERROR Error Code = 500
[21:26:15:146] : Log finished
The phone never rebooted and was stuck in Emergency Mode for 15-20 minutes, so I pulled the battery and tried a hard reset, but the phone doesn't do anything but hang on the LG logo. Any suggestions?
Any help is greatly appreciated.
update: Can't reinstall V10V with KDZ because it doesn't see the phone.
update 2: Used KDZ for V10G in emergency mode with phone in emergency mode (back button + volume up + power)...now we're all good. Thanks.

THE BEST WAY TO COME OUT OF IT IS TO FLASH VIA KDZ FLASHER USE V10B FILE http://csmg.lgmobile.com:9002/swdata...00/V10B_00.kdz AS IT CAN BE ROOTED http://forum.xda-developers.com/showthread.php?t=883314

Hi!
There's no such thing as bricked phone
Just try to read carefully before doing anything, please.
Now read this post and proceed as follows: http://forum.xda-developers.com/showthread.php?t=875881
It should get you up an running in notime. Just reply here if you need any help.
as others have suggested , downgrade to 10B with the given app and all should be fine , also the part where you said it hangs in the LG logo screen is a know issue with Mik's ROM , search in his forum and you will see the solution ( its a file you need to flash before you flash the actual ROM ) also you havent told us wich costum recovery you are using ( best one i think is the Thunderg 1.2.1 )
Be sure to wipe EVERTHING( from the costum recovery interface ) before you flash the new ROM specialy when you go from a 2.2 to a 2.3
I'm confused the phone will not do anything but stay on LG screen. No recovery notta.

Without recovery, the only way you can choose is to send it back for warranty, cry for repairing
That's the risk we faced.

By the way, I've heard that someone bricked his phone and got a new one for free here in Taiwan. Seems like that they forgot to check the firmware D
can you access the emergency mode?
ive been stuck with lg logo couple of times,
but still im able to access recovery,
if emerency mode is working, try to reflash using 10B.kdz
this is my first post, using ROM manager (clockworkmod) i tried to back up my current ROM my device(LG P500) was not listed in the selection screen so i chose LG Ally ( i know it has become a blunder now, i think
the phone won't go past the LG LOGO at the start LG logo appears and just with a few seconds goes off and the phone does nothing
if i put it for charging the menu,back,home,search buttons and the LG logo keeps flashing every few seconds
i can't go into recovery already tried it many times, KDz updater won't recognize my phone it says phone not found(windows doesn't detect it either)..the phone won't go past the LG logo
so is this whats called a bricked phone ? and will i get service for this ? i will beg them for warranty but they will repair this right?
PS:i'm sorry this had to be my first post, and i hope i have not posted this at the wrong place
Adren022, put your phone in emergency mode. See previous posts. You should still be able to use KDZ updater to flash V10B (I flashed V10G).
I don't think clockworkmod works on the P500. Try using thunderg for recovery. See "Installing a custom recovery" here: http://forum.xda-developers.com/showthread.php?t=1007244
you should of flashed a custom recovery try one start up pressing the power button, volume down, and home button at the same time till recovery

I think that's misleading. That will cause a hard reset of the ROM (losing all apps and settings) if Thunderg (or Clockwork for some) isn't installed first. It happened to me.

LG Optimus Me P350 - can't get into recovery

So I wanted to install a custom ROM to my P350 today and it seems I can't get into recovery mode. When I try to get into recovery, it shows the LG screen, shows that recovery mode screen, freezes on that screen, reboots and EVERYTHING ON MY PHONE GETS RESET,
I've tried 3 different ways to get into recovery, all of them have this result. It is very annoying that each time I try to get into recovery the phone gets a factory reset.
Does anyone know how can I get into recovery?

If you have adb setup on your computer you can try running from adb shell "reboot recovery".

Take off your phone's battery. Wait around 2-5 minute. Insert battery. Press vol up + vol down + power button.
Have you even tried a wipe data? Do it at first.
If nothing works...than remove battery and hold the buttons for download mode(volume up+down+power) and than reinsert the battery....u may require a pair of hands more to do that so take anybody's help.....

Thank you guys, at the end I changed the kernel from the clockwork mode, that gave me the normal e3 boot. From there I made a data wipe and then I entered clockwork mode and restored a nandroid backup.
Still I wish I could enter the download mode, but the screen just flashes so... I'll try later this week, right now my friend has it (it's hers) so maybe when she gives it to me again. Right now I left her with stock OS xD

Don't flash Rafael.Baugis CWM kernel without formatting your partitions as ext4
I repeat
DON'T DO IT
It will soft brick your phone
And if you try again and again, it will hard brick your phone
I had to send my phone to Samsung Service centre to restore it!!!

ok it would have been nice to know that -.-'''' why don't they post this info anywhere else? seriously it was a pain to do anything on that phone. I'm still trying to figure out a way to put it into download mode. Right now it works but my friend is asking for the thing that makes the phone install stuff on the sd card so IDK what to do.

I cannot get into the Bootloader

I know how to put the boot loader into fastboot mode, power on while holding up. Problem is, I can't get it to load. It started after installing the SlickV6 Rom. Anyway, when I attempted to load the bootloader, the phone shows a black screen inof the fastboot usb text. Worst of all, rebooting the phone will only boot back to this black screen. I have to LGPNST back to stock just to get the phone to load.
Edit: Ok, LGPNST Again, rooted, unloacked, then tried to use Quick Boot to boot directly to recovery, and I get the exact same issue. It's almost as if the recovery is corrupted and it's not allowing me to load the booloader. Problem is, if I can't get into fastboot usb mode, or recovery, I can't flash a new recovery. This is awesome.

Try redownloading Freegee and rerunning it. After the phone boots up download GooManager, hit menu, and then choose install openrecovery script. Once it downloads and installs, power down the device. Hold volume up + power until you see the LG logo and it goes black with text. Press volume down twice and then power. It should boot into TWRP recovery. Once you make sure it's working you can flash Sk8's CWM recovery, I you want too.
It's the black screen with text that won't load. If I don't unlock the bootloader the phone ignores the button commands. Once I unlock the bootloader, the phone will boot fine, until I attempt to load the bootloader. It just loads a black screen and sits there forever. The phone will never boot past this, even while forcing a reboot by holding power. I'll give your method a shot. Worst that can happen is another LGPNST.
EDIT: Nevermind the above. It's the act of unlocking the boot loader that's actually causing the phone to not boot. After typing the above response, I unlocked via freegee and rebooted, it shows the LG Logo, then just a black screen and it's stuck. Running LGPNST again. I have no idea what could have happened to the booatloader that would cause it to be unable to unlock without bricking my phone.
EDIT 2: Just tried the freegee.bat from the PC. Says the phone has been liberated, but does the exact same thing. I am stumped. I hope I don't have to wait for ATT to release an update so I can run something other than stock.

Looking through the freegee thread, this seems to be a common problem with the newest freegee. Gonna try an older version and see if that's the issue. If not, guess I'm stuck with simple root until I have time to get on irc and see if anyone knows how to fix the corrupted partition.
