Black Screen of Death [Solved for ME]
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.
Charge your battery to at least 70% and backup all important files.
Flash V30A FLS/BIN from HERE
but DON'T REMOVE THE BATTERY
. Just turn off device and boot to S/W Upgrade mode.
After a successful flash. Reboot device.
Download STOCK V30B KDZ for your P990 using your IMEI.
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.
After you have downloaded the KDZ file. Convert or Extract it to FLS/BIN using this TOOL
Flash V30B FLS/BIN using smartflash. Again DON'T REMOVE THE BATTERY
and boot to S/W Up mode.
After a successful flash. Reboot device and root it from HERE
Don't know if it'll work for you guys but there's no harm in trying.
