In some real trouble, help please (G4 H810)

[jasonwebb11]

Hey, I am not sure if I am posting at the right place or should I create a new thread or not, really sorry if I am doing anything wrong, but I am in some real trouble here. I have At&t g4, it was on h81010g stock firmware version, it was working great and I was loving it but I wanted to update it to android 6, so I followed this guide https://forum.xda-developers.com/att-g4/general/lg-g4-h810-upgrade-to-android-6-0-t3323995 to update my version from 10g to 10o and then finally to android 6, 20o, (by the way its a great guide), everything worked fine but I have no signals, I tried to reset the phone and tried a few other things like hidden menu, airplane mode but nothing works,

I couldn't get the signals and shows a small cross above the signal bars, After that I used the LG UP tool to downgrade it to h81010o but still the same, I think my region don't have the upgrades further than h81010g or whatever the reason, I can't find the H81010g stock firmware anywhere, can anyone please share the original h81010g tot or KDZ file with me,

so I can get my phone back in a working state? a question for senior devs, bro if I can't get a h81010g file, what are my options then, any kind of help will be very much appreciated.

Thanks...

There's no other firmwares other than one ones I uploaded in my guide other than 21y which I'll upload in a few hours which was recently leaked (which is a shocker ). Also remember you MUST be on AT&T for OTA updates to work so that might explain why you cannot update via the phone.

I can't speak for that guide and not having service as I've never used it, you did perform a factory reset after doing that correct?

Did you attempt to try another SIM card in the device? And did you remove and reinsert the sim?
