Guys I was downgrading my optimus one's firmware from 2.2.2 to 2.2 v10b by following this tutorial http://lgp500.wordpress.com/2011/03/25/how-to-downgrade-your-firmware-lg-optimus-one-p500/
Unfortunately..the author had missed to mention three major steps in the article. Those were
Disabling the LGE Virtal Modem from my pc.(
uninstalling the ms visual c++ redistributable software from computer, which, can interfere in the updating process and detach all other USB devices
enable USB Debugging(Menu/settings/applications/Development/ USB Debugging.
I missed those steps as a result of which I got a flashing error and now my phone does not go past the LG logo. When I turn it on the LG logo appears immediately, then there's a white screen like u get to see when u get a cable connection error on tv , the backlight keys of the 4 hardware buttons below blink 4 times very quickly & the screen turns off. If I connect the phone to a data cable the phone shows that white screen ,goes off 4 two seconds & reshows without turning off (I didn't need to press the power button)
Now I disabled LGE Virtual Modem. Connected phone to my pc through USB
& pressed "Volume up"+"Return" hoping Yellow screen with text emergency mode would appear but nothing happens. The same thing mentioned above appears. Now please tell me what to do !!!!!
Again go to emergency mode nd try to downgrade with kdz
Thanks buddy !! I unbricked it successfully

i've Bricked (killed) my HTC mega, i just flash it with wrong file and after that it stuck on HTC logo so i just connected it with MTTY and used few commands and it doesn't power on , mean doesn't take power at all now , i used following commands.
1) i connected it with MTTY in Bootloader.

it is true that he says that the phone will not turn on. But from my experience in the assistance of computers, the user loads the fact that the system is reported as "not turn on ". You have no idea how many times I went home carrying the replacement power supply because they said "not turn on", when they appeared "disk boot failure!" and the same thing I already happened with Italian users of smart phones. White screen at power on, boot loader ok but the owner stated that power on. I explained?

hi can someone please help i tried to flash my xperia x10 mini and failed badly and now when i turn on my phone the logo screen comes up and then just stays on... ive left it for about 20 minutes but still nothing its like its bricked on the logo screen i can restart it but it just does the same again. Ive also tried taking the battery out putting it back in then using the update service to lock it in flash mode while i use binarys flash kit but that doesnt work either. Also the update service just says no software update is available it thinks i already have the latest one please help i will be truely greatful x
Edit :
Ive already tried SEUS, PC Companion, Binary's Flash Kit.
Ive already tried connecting it to the adb but cant get adb to recognise a connected device and all the drivers are installed.
i guess you have, but i've to ask, have you tried the repair option in SEUS/PC Companion?
yeh i have seus says i already have the latest software version installed and pc companion actually wants me to load my phone up to connect it :/ any ideas? x
me too!!
i had the same problem with you...
how to get shutdown this phone?
phone must be shutdown when i want to flashing from SEUS..
and i don't know how to shutdown this phone because the battery....
edit : just connect your phone and use restart (hold power button & middle button)
after reboot, press back button and you will connect with SEUS...
but, my phone already get latest update...and i can't flashing from SEUS...
sob..
ive been shutting down the phone by taking the back off and unscrewing the inside cover. Then you will see the battery cable where you can simply unplug it from the motherboard and then reinsert it.
Edit: I also have connected to SEUS but it says i already have the latest software
Ive taken it to a local phone repairs shop ive given up... they said it'll be fresh and working by tomorrow morning it cost me £20 but its just one of those things en it :/
hey guys
all you need is to follow the instructions on SEUS,
when it tells you that you have the latest software press repair.
and when it say that you should turn off your phone and then reconnect it while pressing the back buttom do the following:
1- connenct the phone to the computer
2- press the 3 buttoms (power + mid buttom + back buttom) then as your phone restarts and vibrate remove your fingers from the power and mid buttoms but maintain pressing on the vack buttom
i hope this will help
Hi!first of all this is a great site that i've stumbled upon while google searching on how to fix my phone. Now, the problem started when i updated to ICS. After the update there were spots on the touchscreen that were unresponsive but i'm a physical keyboard type of guy so that did't bother me much when it came to texting but when the need for swiping comes it gets very irritating as my swipe action becomes incomplete. Although it can easily be solved when i'm on landscape mode. Still, on landscape mode the bottom part of the screen becomes unresponsive. Though i can still bare with it. The real problem happened a few days ago when my screen became distorted when used in portrait mode but the distortion disappears when in landscape mode. Then after a while it becomes distorted on both landscape and portrait mode. Everytime i have to unlock the phone the screen just goes black specially on portarit mode and i have to repeatedly press the power button to make the screen appear just so i can unlock my phone. Then two days ago the screen just totally went black but the backlight still turns on not even the logo appears everytime i turn it on. I tried connecting it to my pc to fix it but the phone cannot be detected. I searched and did a hard reset (pressing the power button and home button simultaneously) and voila! the screen works and the logo finally appeared but still distorted. So i plugged it back to the pc and installed the software update. After the update i tried turning it on again but the same black screen i've mentioned happened again nothing shows on the screen not even the logo. I tried hard resetting it again but it didn't work. Please help i really love this phone :crying:
By the way the phone is all "stock" meaning i haven't done anything to it (flashing ROM, etc). please please please help.
Downgrade to GB using flashtools. Maybe that helps
Have you tried repairing with PCC or flashing stock firmware via flashtool? Maybe that would solve your problem, hope its not hardware related :/

yes i have tried repairing it with PCC. The repair finishes but its still only black screen when i turn it on. The phone still vibrates though and the led light lights up when i connect it to pc or charger.
Haven't tried flashing as i do not know how and when i connect my phone to the pc it doesnt appear on "My Computer" and is only read by PCC when i'm attempting to repair it, in which the latter happens rarely.

i cannot do so as the screen is not functional. It is just black with the backlight on. Not even the logo appears when i turn it on.
Hmmmm...i don't believe it's cause by upgrading to ICS....i believe your LCD ribbons is damage...try open and close the keyboard slider slowly and listen to the sound...if the sound isn't smooth then the ribbons is damages...you can also feel it when you slide it open and close it...

First download Flashtools from here: http://uploaded.net/file/9o4swxaa
Then download Mini Pro Firmware from here:http://forum.xda-developers.com/showthread.php?p=27376024#post27376024(choose any firmware for Mini Pro)
Then do this:
Make sure Flashtool is installed.
Place downloaded firmware file(.ftf format) in Flashtool\firmwares(by default C:\Program Files\Flashtool) folder.
Start Flashtool.
Click the lightning button and choose Flashmode.
Firmware should appear there, if you have it in correct folder. Choose it.
Turn off your phone, connect USB cable to computer, then press Volume Down button and connect USB cable to your phone.
Flashtool should detect your phone and starts flashing. Follow the instructions.
When it says „Flashing completed“, unplug your phone and turn it on.

i tried this but after flashing my phone is still the same. black screen with just backlights lighting. any more suggestions?
hi guys, I think my P768 is bricked = '(
he was V10A, I installed v20a on it, I installed the root and cwm. then I flashed back V10A accidentally and now the device is stuck in the recovery screen. The lg updater tool does not recognize it in recovery and when I do power + vol up it also does not work (because of jb i think it) ... I also did hard reset several times, it reboots back to recovery screen, and the flash still doesnt working...
I'm desperate, what do I do?
Edit;nevermind what I wrote before.
Turn off your phone, remove the battery, while holding vol+ &power plug usb cable to the computer, you'll see sw mode, put the battery back in ...
Use original LG tool(lg pc suite). Make sure your hosts file is clean
thanks for the help, but i tried and the tool said "problem with communication between cell phone and pc"... i'm sure that all drivers are installed
sorry for my bad english =/
====
well, i did it and at 15% of analisys the tool said "the usb cable and your cellphone are not connected... please connect and press restart" =/ (i used pc suite also, it didn't recognized anything)
=====
after losing a few hours of sleep worked perfectly in the online tool ... I almost cried with emotion lol, thanks for the Force!!
I have exact issue with 15%. How you sorted it out?

well, remove the exceptions for lg in hosts file, after this restart the pc...
after this power off the phone and connect pressing vol up for s/w upgrade mode. open LGMOBILE SUPPORT TOOL (the same as previously), above the screen click in custtomer support or options, i dont remenber, and look for something similar to emergency flash... after this follow the screens, is simillar to offline flash
Yesterday I rooted my LG Optimus L9 using LGpwn tool, after that it worked just fine.
This morning I tried to install ClockworkMod Recovery. Using this post. It explains how to download and install CWM Recovery from app that you downloaded in form of APK.
This method did not work 100%, but I was able to reboot normally, so in post it said that sometimes it does not work and you need to download and use Busybox installer Link to busyboxx.
After this I managed to boot in too CWM using app from mentioned thread.
Then problem occurred. After I saw CWM was working I selected reboot device option.
Except now when it started to boot it stops right after Second LG logo (First is static one second one is animated).
I get white screen with "Encrypting" on top and gray line. And one Reset Phone button. IMG they are Dropbox links.
This is followed with Error : Unfortunately, the process com.android.phone has stopped. IMG
I am able to boot in too CWM and I have tried flashing something like Cyanogenmod but I get error Status 7. Tried removing line that checks model, no use.
Tried clearing every cache and fixing permissions, nothing. Formatted everything still no use.
Dear XDA community That you in advance.
I fixed my phone by going into SW upgrade mode, and using the Upgrade Recovery function of the LG Software Update tool or whatever. Be sure you don't have any http servers open

And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! ), then the phone begin work~~~
