Root 20f to 20h OTA Update for DEVs...

[JustZaphod]

I pulled the OTA update from 20f to 20h off my rooted phone..
It wont update due the the fact that its rooted, (Locked bootloader though)
I have a T Mobile Lg Optimus L9 P76920f..

It wont update to 20h because im using (jcase method, with locked bootloader)
and because of the root it wont update..

I uploaded the update file from my Cache folder for any Dev to look at and possibly fix so it can be installed on a 20f phone...

Hope this helps..

Edit: For anyone who doesnt know what this is, or what they are doing, PLEASE DO NOT TRY to flash this to their device.. I have no idea what it will do. This is meant for any DEV with the knowledge to mod this for flashing..

Im also wondering if this OTA is flashed.. Will it lose Root?

Mine also fails at about 25% when trying to do the 20H update (I tried at least 5 times), I also assume because I'm rooted (but still with locked bootloader too), or perhaps because I have Link2SD installed, but I unlinked all apps: Not sure how to revert the mount script back to the default.

It would be nice for a workaround to flash this so I don't have to do a factory reset first. Fortunately the phone still works fine on 20f when you reboot after the update fails.

For me it has something to do with my Build Prop being modified..
if I knew what the mod was.. I'd fix it.. I dont have the stock Build Prop to compare it to
