Tutorial: LG P970 (P970H) unbrick/flash using SmartFlash Tool
- Thread starter radkor
- Start date
i guess one reason should be that u probably tried to use P760 stock rom
SFT can be used in other phones, not just p970, but maybe, that guys wasnt the case.
Im having a similar issue. I try flashing with the bin and fls files, but mine doesnt reboot at all. I have to pull the battery and power it back on, but nothings changed.
Heres the files I downloaded. What is the .dll file used for?
Is there a way to flash the P769 with these files?
http://uploaded.net/f/wihfvm
the DLL file is used for the update tool to verify that the KDZ and for LG extract to know how to extract the KDZ to bin+fls format. CMIIW.
I had been stuck on a bootloop where my phone would get up to the CM10 spinning circle boot screen then the screen would turn off and it would show the battery was charging but the phone would never actually start up
I could not boot into CWM recovery although i had previously flahed it to the phone, so i tried to reflash the stock rom following the instructions in the OP
I was repeatedly getting an error when i ran the smartflash tool that it was "trying to communicate with ifx modem" but I would repeatedly get an error that this had timed out
It was not until I read tis post that I tried booting into s/w update mode with the battery out and ten it worked a charm. I hope tis can be of help to anyone else...
SmartFlash Tool completly erases device memory during flashing.
Phone will make Factory Reset at first boot after flashing!
You can upgrade and downgrade. You can downgrade from V20N too!
This also will remove phone lock if you forget unlock code or pattern. (phone lock, NOT simlock or network lock...)
This method doesn't need internet connection.
If you want to flash an LG P970H download correct ROM from link below.
With this solution you can unbrick LG Optimus Black P970.
It fixes bootloop, "ERROR LG Security Team", and BSOD - blue screen with green writings (untested).
Only requirement is ability to enter in to S/W Update mode and not broken hardware.
Tested on: Windows 7 Ultimate x86, x64 and Windows XP Pro SP3.

If you do have a recovery installed on your phone.
1- plug your USB cable on PC
2 - Remove the battery from your phone (remember without battery!)
3 - plug usb cable and wait screen change for a white battery icon.
4 - Press and hold: Vol down first and power button.
5 - hold buttons and wait to boot in recovery!

No COM port detection...
Hi,
I've read this entire thread, and saw only one relevant post to the problem I'm facing.
I understand I need to keep the VOL+ pressed until the computer detects and installs the driver.
However, After having it happen once, and possibly the cable lost connectivity during the driver installation, it just doesn't happen again.
I've tried three different computers, connected the phone with VOL+ pressed for long periods of time... dozens of times.
I just can't get the computer to detect the phone on S/W update mode, so I can't flash anything.
Has anybody had this happen? Know what I might be doing wrong?
Thanks in advance!

yes you can use it for OB, it's recommanded to downgrade with SFT, security error is the message of locked bootloader ICS.
You can't install CWM in official ICS, bootloader is locked, but you can try some custom rom or repack in dev section.

Exactly! It takes only 3 minutes to flash.To add, it is a fast flasher compared to RDTT.
