ATT G8x Firmware Dumps

[Deleted member 11641335]

How do I restore using this?

I might still have a copy on my drive if you still need it

If you still have it, I could very much use it.

Just want to offer a warning to anything thinking about using the above referenced backup - I used it myself on a soft bricked G8X (AT&T) using QFIL on EDL/9008 mode to upload the unpacked IMG's. I went from soft brick to hard brick.

When I first started off using this I uploaded only the system, boot and abl...when I started seeing a fastboot screen (which I hadn't seen since) I felt like I was moving in the right direction so I uploaded the remaining partitions. After exiting EDL the device refuses to turn on...no LG splash, no android warning, no longer any access to download mode. No amount of button pushing brings EDL mode back while connected via USB. Doesn't charge using wireless charger (which it used to before).

I'm very confident I did not mismatch any partitions, though uploading the OP image did mention that there was data overflow and asked me if I wanted to continue. Further, this backup did not contain all of the img's that would ordinarily be present in a KDZ, but contained imgs that a standard KDZ do not have.

Since I can't get to EDL I can't restore the backups I had made of it's previous soft-bricked state.

It's just really frustrating, and I've learned my lesson never to buy a device from a carrier that doesn't allow access to it's KDZ firmware file (or cannot be crossflashed to one that does).

Your mileage may vary of course but I definitely feel like I'd want to stop someone from trying the attached if they're still in a soft-bricked state.

As an aside I would appreciate anyone who might have any ideas of how to reach EDL mode again. Thanks

so is this thread considered useless.. there is no way to back up and restore this ATT phone firmware?
LG provides no support?
ATT does not let you update it unless you have active ATT sim....

Would you consider sharing your LG-G850UM backups for AT&T the version?

Any g8x at&t stock firmware?

 

[gearmaker]

I have a g8x sprint that is UICC unlocked for any sim.It seems eBay is dumping a lot of
Sprint phones.However, this one is unlocked but on Good2Go mvno (att) volte is
not working. IMEI on att site says it is approved phone. My question is:
Can att firmware be flashed to this phone to make volte work?

Did anyone have the G850UM10F android 10?

You will have to open the back and short some contacts.
Or give to service center if in warranty.

any idea which contacts you would have to short? hard bricked my g8x too

The testpoints should be similar to the G8S.Here's a picture of the G8S.
