Black Screen of Death [Solved for ME] - LG Optimus 2x

I suffered with BSOD on my Optimus 2X P990 for months under GB and ICS V30A.
It happens anytime and when I charged or plugged it on the PC while the screen is off.
It really sucks removing the battery anytime and turning it on again.
But after flashing ICS V30B and rooting it, it seems the BSOD is totally gone.
It never occured for 2 MONTHS now!
Also tried it with some units I sell that has the BSOD bug and it never happened again.
Here's what I did.
1. Charge your battery to at least 70% and backup all important files.
2. Flash V30A FLS/BIN from HERE but DON'T REMOVE THE BATTERY. Just turn off device and boot to S/W Upgrade mode.
3. After a successful flash. Reboot device.
4. Download STOCK V30B KDZ for your P990 using your IMEI.
Code:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=[COLOR="Purple"]XXXXXXXXXXXX[/COLOR]
Where XXXXXXXXXXXX is your device's IMEI. Browse to that page and a link will be shown where you can download the specific V30B Kdz for your device.
5. After you have downloaded the KDZ file. Convert or Extract it to FLS/BIN using this TOOL.
6. Flash V30B FLS/BIN using smartflash. Again DON'T REMOVE THE BATTERY and boot to S/W Up mode.
7. After a successful flash. Reboot device and root it from HERE. END!!
Don't know if it'll work for you guys but there's no harm in trying.

Ola!!! I tried it on my P990. I also have the problem. But after 3 days no more shutdown for me but I will test more. Anyway muito obrigado my friend.

can i flash v30b im not in that country region ?

Yes, but you might have to let go you're language...

I thought V30B was for Asia. Will the mobile connection work well in Europe?

[Q] Semi-bricked / Smartflash tool not working

Hi
I'm helping out a friend, which O2X I have rooted and flashed WIUI on to (I previously owned one myself too)
For some reason the phone started to get hot after a while and used up the battery fast, until one day where he couldn't even turn it on again.
Now, he has been trying to fix it himself with NVflash, but no luck, so now its up to me and you guys.
I have used the smartflash tool and flashed the EURO OPEN stock ROM and everything went succesfull, but when the phone reboots, the LG logo appears, and it bootloops.
I tried both with battery and no battery in, but still no cigar.
Any suggestions what I should try next?
PS: If I try to turn on the phone normally, nothing happens. not even a blink from the screen, but I can get into S/W mode and APX
Try lg update tool, choose recover as option, then choose imei as entrance

EDIT: The software says the update is not compatible (dunno if translation is correct, but you get the point)
Update is aborted :/
No more suggestions on what to do?
Tried:
NVflash
Smartflash (Flashed EURO OPEN rom)
LG Update tool (recover function)
The phone still won't boot.
Smartflash is the only solution like you said that the phone can boot in s/w mode try to dig some answer in smartflash thread or search in google i know you can find some answer there

Assuming you have carried out the procedures correctly, looks like this device is actually defective. Probably not what you want to hear, I know, but...
Before giving up completely, you can NVFlash it again (using the original 10C NVFlash from Modaco) and post the log here. Wouldn't get my hopes up though.

Urgent - seriously bricked LG P970! Plz help

My LG Optimus Black P970 is bricked, its stuck at LG boot logo n I have already tried the following methods to unbrick:
1.Smartflash (flashing fls & bin files- flashes successfully but still stuck at LG logo)
2.LG Update tool - Recovery mode- flashes successfully but still stuck at LG logo)
3.KDZ (fails, coz phn not booting in emergency mode)
The guy at service center said the circuit may have been damaged coz he was unable to find the COM port (but I still get a COM port automatically in Smartflash tool) for his official LG upgrade tool. Do u have any idea if its possible to unbrick this device?
I have had such bootloops earlier, but I solved it using CWM recovery when I had it installed, while I used the recovery mode of LG Update tool (B2C) when I didnt have CWM recovery installed. This time nothing's working!!!

Did you already try to boot to recovery via adb? If not, do it abd restore a nandroid then. What ROM did you have on your phone before it bricked and why did it brick?
And please someone report this thread, so it gets moved to Q&A, I cant, because I am on the phone...
Sent from my LG-P970 using xda app-developers app
Unfortunately, adb is not recognizing the device after bricking, but LG Update tool and Smartflash both are.
I had flashed 4-5 unofficial Jellybean and ICS ROMs in a span of a week before bricking. The latest OS I had flashed was LG official Gingerbread (which is when I lost root and CWM) n everything was working great, then I again badly wanted Jellybean, so I flashed a patched 2.3 OS using ROM converter (only to bring root again, coz this time unlockroot could not root it) n since then I have flashed using all the above mentioned methods countlessly, to ultimately brick it badly.
Left battery out of phone hole night, then put it in, try to start phone.This helped me. Is good to have battery charged.
Good luck.

remove battery, enter in recovery mode : vol + and plug usb , flash with SFT with a good rom
Thread moved as questions do not belong in Development however urgent you feel your question is. Please post in the correct section going forward.

I just installed the official ICS using Smartflash like u said, but my phone could not unbrick . I guess it might me a hardware failure. Any ideas?
I have a similar question: my friend wanted me to upgrade his FroYo software to ICS on her P970, and it kept failing the upgrade and it now cannot boot, having "Software upgrade" sign on the screen all the time...
Any ideas? Thanks in advance!
To niraj87:
To have battery charged at least 90%.

Maybe you already done this but did you md5 checked the files you are downloading?
You maight be trying to flash a corrupted download.
Just a thought.
Hope you can unbrick your phone.

Just to make sure, download md5.exe (if you are on windows) and run the command from the folder (exe and the downloader file in same folder)
md5 Name_of_downloaded_rom.zip (or anything)
You will have to have the original md5 hashes (if you download from dev host you can have it from the download page)

lg p970 problem flashing,reset

i messed up my lg with installing ICS,now when i turn on the mob everything is blocked,picture of android is v10 and version inside is v30,i can charge it and i can get in s/w update mode. i tried smartflash but it goes to download complete but mob. wont reboot just turns on lg logo,i tried kdz updater but when i press upgrade start and normally its supposed to ask me which country to choose so i can put different country in my case it goes automaticlly to update. i have teamviewer 8 if maybe someone has time to help me so i dont have to take it to service(no money). thanks
now in lgmobile tool i did phone recovery and after i turn lg on on version it sais v10a and it sais i can start update to gingerbread and when i start on update on 15% it stops,any help?
after error i put manually in s/w update mode and it went all the way,it sais gingerbread installed but cell want reboot and when i turn it on there is no change.
on 90% of update on cell comes lg sign and stayes like that
hey man sorry for the late, I'm a little busy
just a question, when you flash a patched firmware, can you access to the recovery ? if yes, that's all, from there just do a wipe of datas (flash superuser if root is needed) and reboot. done.
no problem its never late, unfortunately not,thats was i am trying to do,i know i need to come to recovery but so far i didnt manage
which firmware did you try ? (give a link if possible)
unfortunately i am at work but i dowloaded v10a from, http://lg-phone-firmware.com/index.php?id_mod=1
these from that site are not patched, but stock...
download this (run to extract binaries) and follow my pdf guide if you have already the upk package
edit : or follow this online guide
ok i will try with this,can you just tell me will i try with kdz updater or with smartflash?
smartflash of course.
kdzu is obsolete since LG has restricted this method (there is a way though, but more complicated)
i have upk ofcourse,i tried so many combinations,maybe i tried even v20s patched but i will give it a go tonight after 10 p.m. when i get home and i will post results,thanks for now Ilko
Ilko this stock v30 recovery,would that maybe help in my case?
If you need a reset, it won't help,because as said before, ICS stock firmwares don't have recovery
From my funky phone
here i am,i tried,download went ok but cell is stuck on lg logo
with vbscript i managed to run r&dtt and change country to diferrent but on 90% always cuts me off,i noticed in device manager that it cuts usb connection,i know that i must put cell on usb debbuging mode but i cant when my cell is completely locked when its turned on,is there any solution for this or we can say i can through it away??
well, I don't know what to say friend. if smartflash fails, other ways will fail too. you may try r&dtt with the shttp tip. I'm afraid this is the last chance
Hmmm, what if he tries to flash a stock ICS? Since SFT tries to reboot in recovery mode, it will wipe data, and maybe will help...
As long as it doesn't drop the usb connection, of course
Sent from my LG-P970 using Tapatalk 2
i used v30b and sft download complete and it turned on lg logo and stays like that,no reboot, with shttp tip i tryed again but it always cuts me out on 90 %, do you guys know if i take it to a special shop for mobile they could reset it with some special cable or something????
when download on smartflash completes usb immediately disconects me and than cell can not reboot,smartflash automaticlly finds a com port,do i need to do something manually with installing drivers or something?????

S/W upgrade mode problem

Hello there,
I rooted my X3, unlocked bootloader, flashed CWM and Upgraded to V20A and everything was going great.. Till i decided to flash eternity kernel since people's feedback in their replies encouraged me to do so..
So i downloaded the eternity kernel version for stock rom, flashed it and it did 2 very bad things to my phone (i honestly don't know why this happened only to me.. No one reported such errors)..
First, i had boot loop stuck on the LG logo animation that kept repeating over and over - endless..
Then, when i tried to go to s/w mode (holding vol- while connecting the cable) i am getting white screen with tiny black lines! And the phone is not being detected by the computer (of course i have all drivers installed).
So i overcame the boot loop problem by flashing eternity kernel version for CM as well as the CM 10.1 nightly rom over CWM.. And am luckily able to boot and use the device..
I just still can't use kdz anymore cause of the s/w mode malfunction..
A friend suggested flashing the LG stock kernel.zip for V20A over CWM since i have it and since i didnt get the s/w mode error except after i installed the eternity kernel so he's linking the error with the kernel, could that be correct?
If it is correct, I'm not sure if stock kernel for V20A is compatible with CM 10.1 or will mess my phone even worse?..
Sorry for the long post but all what i need is to see my baby back in s/w mode so that i can use kdz
And in case i have to wait for the final kernel by eternity, is there any workaround to get it detected by the pc for kdz upgrades without going through the s/w mode?
Any help will be much appreciated!

[Q] LG Optimus 2x stuck after flashing

Hi,
I’m trying to upgrade my Wind Mobile Optimux 2x from 2.2 to Android 4.2.2 (CyanogenMod Nightlies). The Clockworkmod identifies my phone as LG G2X; I tried to manually select Optimus 2x but flash recovery failed. I kept it as LG G2X but each time that I tried to flash with a P990 ROM (Optimux 2x), it was unsuccessful and I had to factory reset it by pressing Power and volume down key.
This time, I selected P999 ROM (LG G2X) as I read that it’s the same as Optimus 2x for T-Mobile...but now it stuck at the LG logo (with blue/purple background lines) and pressing Power and down key doesn’t work anymore and it stops at logo again instead of resetting.
If I hold the volume down key until second LG screen, it shows: S/W Upgrade Please wait while upgrading... and it stops there forever...
What should I do to resolve the problem? And is there a way to go back to factory setup mode?
Thanks

First of all, check the sticker under your battery for whether your phone P990 or not. Please let me know what type of phone do you have P999 or P990

It's P999. I spend several hours to research about it and tried different applications...One-Click-G2x-recovery-flasher-04-28-12 and CWM_5.0.2.8_P999 cannot flash the device and give the partition download fail error, maybe because I previously used AIO-P990-ToolKit_v5.6 to nvflash it as APX drivers are installed and USB cable is working well. I tried different custom recovery versions using AIO, ICS-cwm-6.0.3.1, ICS-cwm-6.0.2.5 (before knowing that I have to use G2X), ICS-cwm-5.0.2.8e and ICS-cwm-5.0.2.0 but was not able to flash it as it goes back to recovery mode after rebooting, instead of running the new O/S.

I can do for you a nvflash for your p999. It will recreat all partitions and etc and will flash cwm p999 recovery to your device. Search custom roms on the optimus g2x forums. It will take some time since i have to download a stock p999 rom and gather the necessary files
Download my attachment and run flash.bat. It repartitionate your phone to p999 layout and flash cwm as well. Do not flash p990 custom roms with cwm to your phone, because p990 and p999 partition layout is different.

Thank you for your reply. I finally could flash it using G2XCleanUpBatch5028. It turned out that CM7 unlike what I thought is 2.3.7 not 4.x and I already found some problems in it...I'm trying to find the original Wind Mobile ROM and a way to install it back on my phone to keep it as my factory reset backup to return back to it in case that I could not find a reliable custom ROM.
By the way, I'm wondering what's the difference between your attachment and the one (G2X_V21E_00_NVFlash) that comes with 450MB ext3_system.img file?

My version of nvflash I skipped the system image, because I assumed that you are going to flash a custom rom. So that 445 mb differnce is teh missing android OS.
You can find your original rom at http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=0000000000000000 , replace the zeroes with your IMEI number. It will give you the download link for your current stock rom. It is in kdz format. If you having troubles flashing kdz, then give me the link to your kdz and I am going to make you a nvflash rom from that.
