Put your imei no. in this page and check for latest firmware available,
It will show msg like, "Download firmware, version V30 or V20"
if its showing V30 then its lollipop, download it (1.65gb approx) and use LG flash tool to flash it
Edit: from next time, don't start a new thread !!

LG V10 - AT&T H900 but VS990 Mainboard Android 6.0 hole (crashing APPs) any news?

Hi everybody,
like manny other user, I've tried too update my H900 and didn't knew, that the Mainboard is from VS990. I used the LGUP flashtool and web_h90021w_00_0921.kdz stock rom from this forum, because I'm in Germany and won't get any OTA updates.
Now, like all the others, I am in the Android 6.0 hole. That means the device is starting but VPN, Fingerprint sensor and some other apps are crashing and I can't downgrade or upgrade or do anything because of locked bootloader and downgrade.
I will never ever use a LG device again! The software and hardware versioning really s...ks, you can call it bad engineered and bad managed!
Is there any solution to solve this problem and get a working device in the end? No matter which Android version, no matter if rooted or not, no matter if temperary bricked or not.
Just ANY solution of his issue?
Best regards
Evtoda Gi
No solution found yet!
anyone found h900022w OTA software?
Hello, I happen the same as you. I really regret it, but the tutorial never specified certain things.
Has anyone found a solution?
How much longer do we have to wait for ATT & T to remove MM with its mainboard?

Install a different version KDZ on LG RS988

Hi there fellas, I have a silly question:
I have a LG G5, RS988 version currently working on the RS98810h version (Nougat). I've been facing problems with WiFi HotSpot (I have a togle available but I can't configure it) and that made me wonder whether if it is possible or not installing a KDZ from a different region (e.g.: H850, H860, etc.) to a RS988.
Any ideas or volunteers? Thanks in advance for your time :highfive:
you had to root, install a custom recovery, install an old kdz for the rs988, then install the right one and have to be a kdz for rs988 only!!! RS98810h is for brightpoint and this have no hospot option, i had to do all of this to fix mine, i installed 10h by mistake.
