[GUIDE] Recovering from brick/bootloop

pandaball · May 1, 2012

So there have been a spate of people bricking their O3Ds lately... this is the last ditch method to recover your phone if you can't boot into Android, or CWM. No guarantees, but should work so long as your phone is still detected.

Download SmartFlash, then the corresponding packages for your phone:

---P920---
Baseband: http://d-h.st/xci
Baseband Mirror: http://goo.gl/yDnjP
Rom: http://d-h.st/WTE
Rom Mirror: http://goo.gl/UfG85

---P925---
Baseband: http://d-h.st/EBF
Baseband Mirror: http://goo.gl/mdLBn
Rom: http://d-h.st/gTO
Rom Mirror: http://goo.gl/auYkj

Extract smartflash.zip, install both driver packages. Then, run Windows Enabler, in the notifications bar, click it and make sure it is set to 'on'.

If you downloaded the rom from my dev-host link, unzip the .bin file.

Now remove your phone's battery and sim card, press volume up and connect your phone to the computer. Hold volume up until it is detected by the computer. It should take no longer than 20 seconds.

Now run B_SmartFlashTool_Extern.exe, go to rom copy d/l, select LGP920_CP.fls or LGP925_CP.fls for CP bin and LGP920_AP.bin or LGP925_AP.bin for AP bin, depending on your phone model. Make sure under communications setup that your phone is connected (verify the com port in device manager) and then click start. If all goes well, you'll have a working phone on v21E (P920) or v20P (P925) stock

Thanks for the links! However your P925 V20P baseband link is down. Can we get a mirror?

There was this one already, I used this method countless times. It's basically the same thing, but uses LG flashing software and kdz files, which are easier to find, download and flash. You can also use the marwin one with windows enabler and the hosts file tweak (that's what I use on a win7 x64 machine). I can't get why it hasn't been stickied or something...

Yes I know of that one, however it requires you to download so many pieces of software and block LG in the hosts file. This also works on all windows based systems and does not require just XP. Furthermore, if you're phone is bricked, Marwin wont work if your phone is bricked as your phone needs to be turned on and within Android. This is the simpler method to recover your phone without too much fuss.

Actually it does, just last night I used Marwin to flash the phone while it was in emergency mode, download mode (as I knew it when I had the LG gt540) or whatever it's called (volume up, plugged in, detected as a modem). It's not the first time either.

As for which option is simpler, I guess I have to try smartflash, because I don't know why i had this idea that it's a complicated and unstable piece of software

This metod never worked for me. Had the same problem. Ive heard that changing the Baud rate , speed of com port where lg is detected, helps sometimes. It didnt help me, but try and see what happens.

You can't format user data or the /data partition?

In any case, try flashing CWM and see if its able to wipe the partition for you.

Wonderful, thank you! When everything else failed.... you became my new saviour. Cheers.

This doesn't work for me.
I launched getril and it tells me that the RIL is 21e, but the baseband is XMM6260 and it recommends I switch to a 21d RIL.

Why would it recommend that you switch to an older baseband?

ofutur · Jun 24, 2012

Not sure, but this baseband or smartflash method is not working for me. I can't connect to the mobile network.
I've tried a different rom based on 21e and got the same result.

See if you have IMEI.

No IMEI, network, phone number, signal, etc.
And I've tried 2 different SIM cards.

Just flashed the bin with LGFlashTool and this time everything works as expected, so it seems that smartflash is not doing a great job. Maybe it's not catching some errors? LGFlashTool wouldn't flash the files if they were stored on the network, but smartflash never complained.

Getril still says RIL/baseband don't match, but this time the baseband shows as LGP920AT-00-V21e
