I have recently purchased a Korean LG G pro 2 F350L from local shop. The sim was working but before using the phone I factory reset the device and after that I am not able to get network. There are no signals. I re flashed the phone using stock firmware but no benefit. Could it be a hardware problem? How to troubleshoot in correct way.
I bought a V10 H901 in Aliexpress and the IMEI sayd that was a H901BK. It was with the T-Mobile software and Android 6 MM. In PC it said the H90121j and I wanted to upgrade to 7 Nougat and I put the phone in the PC and after the update with LG Bridge it just bricked. Died and do not back to life. I unbreacked my phone with this tutorial:
https://forum.xda-developers.com/att-lg-v10/help/lg-h900-unbrick-via-qfil-t3739309
The Unbrick H901 SD card didn't work, but this worked.
After that, I tried to install all H901 firmwares and didn't work. So I decided to install the H900 firmware and the phone finelly worked. It's working everything fine with no malfunction. Just the Android back to 6 MM, but with the AT&T apps.
I didn't understand nothing. My phone was a fake H901, because is a Refurbished phone. I'd like to install the Nougat update. Is it possible?

Just check at&t website= https://www.att.com/devicehowto/tut...bystep_KM1134561?make=LG&model=LGH900&gsi=oyB
at&t is just behind as always with updates. The other carriers like Verizon, T-mobile etc just push the updates to the devices without sim card or other crap steps

I have same exact problem with same refurbished phone h90121j I unbricked with the same method but I cant install AT&T software because LGUP says that I can't go from H901 to H900. I can flash any other H901BM firmware but my phone bricks again and again.

You'll probabilly need an Octopus box to reinstall the firmware. Try to find someone who can help you with that.

I have opened the phone and find that the motherboard is from VS990 (Verizon). What a scam!

Yes. I have used this method to unbrick from 9008 mode and get download mode https://forum.xda-developers.com/att-lg-v10/help/lg-h900-unbrick-via-qfil-t3739309
Then extracted dz from AT&T H90021w.kdz using LGExtract.exe
And then flashed dz to phone via LGUP.
It's strange but AT&T firmware is only one that working in this case. On my phone without any bugs, fingerprint working, can install apps from play store etc. Only downside is that you will be stuck on Android Marshmallow but at least you'll get working phone.

i followed your same method, mine was a tmobile h901 with korean mobof600l , no other firmware worked except this one, so now my tmobile became a at&t with bugs, fingerprint ,vpn, even imei is zero cant make calls, . i didnt use dz just the kdz directly and it work, can someone tell if using dz brings back the radio and fingerprint,

Probably this method wont work on korean models without bugs. Not sure about kdz and dz. You can try.
Thank you so much!! I tried for a long time to restore the phone, finally the phone works, YOU ARE DIRECTLY HERO))
Good day everyone!
so i got an LG V20 for a sale price in AliExpress.
I bought the H910 variant, which is ATT
After 20 days on shipment, i got the phone as described, but after i did a little digging it turns out to be a confusing variant
Here's what i found:
> The phone boots with a Claro animation, Claro is from Puerto Rico, Right?
> on the "about device" the appearing model is an H910PR. PR is, again, puerto rico
> LG Bridge can't identify the model, will try soon on LGUP
To settle things, i looked up the hardware instead...but it just got more confusing
> I ordered an H910 ATT variant, the back label behind the battery of the phone also shows H910
> looked up the IMEI and it shows as H910 ATT LG V20, both IMEIs from the firmware and the back of the phone is the same
> i teardown the phone to look for the board model number of the device, and it says "VS995"...... the board is a Verizon variant
> again, i bought an ATT variant, the model says it is H910, but the back cover of the phone is written Verizon (i know it's not solid proof that this phone is Verizon or not cuz you can swap back covers, but still)
My purpose for this phone is to unlock and root it, but sadly i can't cuz i might end up bricking it for flashing the wrong stuff because of the confusing models
And even just restoring the firmware could be risky
So how can i root this phone?
Will DirtySanta work?
What firmware should i flash in case i need to restore it?
Any kind people out there to help would be greatly appreciated

Sounds like you got a H910 with Claro firmware on it, could be a refurb phone
Sent from my LG-H910 using XDA Labs
I'm not surprised that the board says vs995, heck my first v20, a us996 I unlocked through LG (means it was indeed a legit unlocked us996, which I bought new) said vs995 on it inside. The single sim v20s are all nearly identical, mostly its just modem and cpu fuse configuration, note that we can't super easily change the actual modem config now that its actually assembled and fuses are popped, but there is some degree that modem firmware sorta works even with cross flashed firmware).
It might just be that the imei tool used couldn't bother to distinguish h910 and h910pr and just labeled them both ATT.

so basically LG is using the same single sim board but with different modems? That's something

So would it be fine if i flashed a regular ATT firmware on this variant?

Most likely.
Att decided to be special snowflakes and did otas in a way that means theres no firmware files that can be flashed through the regular lg up/lgbridge tools though. So the best way imo to get att firmware is to downgrade to the dec 2016 security patch and root and grab an att rom. If you cant find an old enough h910pr firmware then just follow the regular h910 guide involving crossflashing to h910. Regardless I'd at least follow the bit about dumping your modem related files (because if anything is going to get funky, it will be the cell service)

Follow Phoenix's advice and back up your modem, others who flashed att firmware on the pr variant others had issues with cellular service, also you might want to verify what bands that variant supports to see if it will work with your carrier

Will do, thank you all for your response
Hi, I got the lineageos 17.1 in this phone, but the IMEI is stuck at 0...
I tried using the motorola original firmware, but the baseband goes away and it turns into unknown, something like that happened to all the firmwares for this phone in loli, but one...
The one that shows up a baseband, is really unstable and the IMEI still 0.
At least with lineageos and the NON-HLOS file from the latest motorola firmware, I see the baseband is not unstable, but the IMEI is 0...
note: I have no clue on how to make the blankflash thingy work...
try smart assistent for motorola will download correct firmware

Have bought several "refurbished"LG phones from Aliexpress over the years and apart from a G3 have had no problems when flashing/updating firmware by ota,lgup or lg Bridge. At the moment have v500n20x firmware and if i check for updates in settings am told " using latest software version". Lg Bridge tells me v500n20z is available to update and I checked and there is a v500n20z kdz out there. So has anyone successfully updated these ways? Also would not having 20z firmware stop phone from ever updating to Android 11. Am sure years ago i updated G3 using LG Bridge and all seemed ok until i realized no mobile network coverage. Apparently seller must of modified/flashed modem that worked in my country and update put it back to stock. The V50 v500n all checks out in Aida64,CPUZ and imei checker as genuine but thinking of it now ,if i was going to update would LGUP(Uppercut?) be the the safer option baring in mind it's a "refurbished" Aliexpress LgV50

My Korean version LG V500N has already updated to android 11 just one week ago, my device is with "KT mobile" vendor but I'm using it with Telcel and Movistar providers in Mexico without problems, well except OTG connection, my device is unable to use OTG, no matter how many times I connect via OTG and select file transfer in USB mode it stops connection to reconnect after just a second again in power supply mode
