Hello everyone,
I have a P760 with V20I firmware, unlocked bootloader with CWM. I made a mistake : I tried the update through official firmware feature. It restarted my device and instead of doing the update, it went to CWM recovery menu.
Now, I am trapped on an infinite loop with this recovery menu : when I exist CWM recovery, it restarts CWM instead of the phone firmware.
I tried to restore a backup but it still restart me in CWM .
Do you have any idea how I can restore my phone ?
Thank you very much for your help.
EDIT : I tried to fastboot my device and restore CWM, I am still locked in the recovery start loop. I also tried, with fastboot to set TWM as a recovery, I still have the same issue : my device automatically reboots in TWM.
I spend 6 hours trying to apply my own advice :
http://forum.xda-developers.com/showpost.php?p=40423549&postcount=2
The only mistake I made while my phone was in "S/W Upgrade" mode : I did not put a battery in my phone and while the official LG tool access to the phone, sometimes, it "stops" the USB alimentation (which cause a phone without battery leaves the "S/W Upgrade" mode).
Now my phone is back but after spending 6 hours doing all kind of possible tests for a stupid mistake, I just want to hang myself...
Someone have a rope ?

Thank you, just as I said in the next post, my mistake was only to not put back a battery inside my phone while it was in "S/W Upgrade" mode (because, to access this mode, I remove the battery, plug the USB cable and press Vol+).
Where can LGTool be downloaded?
http://forum.xda-developers.com/showthread.php?t=2085344
Download KDZ_FW_UPD_EN.zip, extract it then start B2CAppSetup.exe : if you haven't lock LG site access, it should download the last version of LG mobile tools.

and how you flash from recovery ? i think i can only access the emergency mode now >.< really need help now.
thanks alot for responding !!
im at my wits end, and everything i keep refreshing the page, no one reply. until u.
thank thank
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".

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] : TYPE_WPARAM_UPGRADE_ERROR
[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
Sorry bro did the same thing your phone is bricked. Its a 200$ paperweight

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.
Pls help me out my phone is stuck up in start up screen after flashing recovery-clockwork-3.0.0.5-heroc-20110121..i restarted and it just hung up and whenever i put charger it just keep showing LG logo not even showing charging action.and device can't be found by windows xp system too. the main thing i just updated to andriod 2.2.2 and rooted.so will it void my warrantyor can i give it for service to LG service centre.because its just 5 months old phone.so pls help me asap.
Try flashing back original firmware using kdz updater in normal mode or if it fails enter into emergency mode manually(pressing Power+VolUp+Back buttons) and flash the kdz file.
Refer to the following thread
[HOWTO] Phone not responding at all - last chance to repair
For clear instructions on using KDZupdater(KDZ-FW-UPD.exe), I suggest that you follow the instructions from this thread - [HOWTO] Rooting, Installing - Android SDK, Custom Recovery, Custom ROM's
except that in step 13
you have to select the PhoneMode as EMERGENCY if the phone is in emergency mode
or
select CS_EMERGENCY mode as a last resort measure if the phone does not show any sign of life.
If you want to install ClockworkMod Recovery, I suggest that you read this thread - [DEV][UNOFFICIAL][RECOVERY] ClockworkMod 3.0.2.4
Thanks mate.i have given it for warrenty repair and they replaced the board without hesitation within 1 hour i got my phone back.!
so it was a problem with the board???
or was it a software problem that was fixed since they replace the board???
actually the custom recovery have spoiled Bios of the phone but they have replaced it with new one (free of COST)))))
I have tried the LG update software, nothing detects the phone, it instantly boots into emergency mode hoping I have not bricked the phone. This all happend while trying to downgrade the baseband and it just stopped at about 25% and stayed there for ten minutes, I attempted to reflash and the same failure happend, I then rebooted the phone and it has been in emergency mode since then with no detection at all.
did you flash a custom rom? or were you using the stock lg rom
try use other usb port ???

check downgrading ur phone detail just flash ur desired android version.
if sucessfull via lgmdp(latest method) search threads for lgmdp method or use kdz which solved all probs.
Try to enter emergency mode with vol up + back key + power button (not just power button) and then connect it to usb.
I have tried the kdz(after emergency mode issue) and lgmpd method already as it was required for the baseband flash the first time, I have clockworkmod recovery installed and cannot boot to that, was downgrading the baseband so I could go back to using CM7, as we speak I tried using CDMA setting in KDZ and I seem to have gotten a response, will update with whatever method works to unbrick
well after using KDZ method in CDMA mode, with shaking the phone, crossing fingers toes arms legs and eyes, I flashed riginal firmware and unbricked my phone, thank you for the links, after about 8 different pages I managed to get it working thank you all

Hello, my P500 is not detected any more by computer!
I looked over the internet and it seems a hardware problem. The phone is charging but cannot be detected as hardware. Unfortunately to resend it to warranty I must first remove Superuser because I rooted my phone. Is there any way to install the firmware once again from the sd card? I cannot make it through a computer because as I said before is not detected. I have custom recovery installed: ClockWorkMode 5.0.2.0. I looked over this forum and found some custom Recovery Zips, but I don't know how to use it. Any idea please? I must get rid of root access so I can return my phone to warranty! Thanks!
[THIS IS A FIX]
So I rooted my LG Optimus 4XHD it was running the stock firmware and flashed ClockWorkMod recovery but when I tried to get into the recovery i got this message:[LG security] Error boot image signature. And the phone rebooted so I couldn't enter my recovery anymore but i was still able to boot into android. Luckily there is a very easy fix for this problem.
The Fix
!Make sure that you have the LG drivers installed on your PC!
You have to reflash your system using LG Mobile Support Tool.
In this video a guy describes how you reflash your phone (he is using a G pad but it works on the 4xhd aswell)
This video helped me fix my device
(To get into download mode on the 4XHD: Take out the battery and reinsert it then hold volume down and plug in the usb cable )
You will lose root access and your custom rom (if you have one). But after the procces you can just root and flash it again
For me this fixed the problem but always do it at your own risk.
Hope this helped. Good Luck!

Dear XDA Members,
My P765 now is on Bootloop, it wont load the OS. Before it happened, the phone was fine with CM 10.2 and CWM Custom. I try to flash again an TWRP which can only use to flash CM 11 Unofficial. After i flash the recovery, it went normal. I restarted the phone, and the phone was working. I copy the CM 11 then i try to flash it by entering the recovery again, but the method just open the fastboot page, not the TWRP. and now the phone bootloop on LG logo. I try hard restart, and it couldnt work. i try to flash again the KDZ but the KDZ updater said my phone not recognized. Does anyone knows what should i do to fix my phone? :crying: Thanks before.
BR,
CR
HELP!!
Even my LG-p765 is stuck in boot loop... actulally ringing boot.
But for me it happened during flashing recovery for the 1st time (i used tool tip for doing it).:crying:
Now my phone shows LG logo (just for a second) and restarts. This keeps happening unless i pull out the battery.
Please post, if anyone know how to recover from this the ringing boot.
If you can manage to get into fastboot and flash uboot and xloader, then connect the phone on software upgrade mode, it should connect. Although there is a catch, THIS WILL RELOCK YOUR BOOTLOADER.
No, it won't. If he install kdz by normal usb cable (not 910k), he will still have unlocked bootloader.
