Root [Virgin Mobile/Sprint] Optimus F3 HARD BRICKED

[cesarasm]

Hi, i have hard bricked my lg f3 to pre-dead "Qhsusb_dload" stage flashing wrong rom using kdz updater with black screen only so i can't get it to download mode,emergency mode etc and i don't have a back up to recover from it.I searched google and found i can flash it to normal with Qpst tool used for Qualcomm processors like f3but i think i need emmc contents, rawprogram0,patch0 xml files.If someone can post these files i think i can have some progress to revive it.Somewhere here i've read that now lg f3 owners can make nandroid backup and it might be useful to obtain these files,so i hope this might work.I'll post any progress so the info will be used to make a guide for recovery from hard brick state.Thank you.

Is this just from flashing the cm rom? or did you do something else to cause this?

 

[cesarasm]

no, it was because I was making changes to the kernel, ai tried installing via cwm

Ok. I'll take a look at the rom. I'm not sure to fix your issue. Can you connect it to a computer or manipulate it in any way?

in PC shows its identified as QHSUSB_DLOAD.
Seems like it's qualcomm download mode. No ADB no Fastboot, no nothing.


it seems like there is a solution for another phone with a similar problem: GSM-Forum but i'm not sure if it would apply for f3? I tried it and the QPST software does recognize my phone in download mode. i guess i just need to have the correct .HEX and .MBN files and flash it using QPST..?
