How can i get back to stock with these files.

[minos316]

The only full stock files I can find for my original stock fw are here. are from handy-faq
they are OTA zip files.

This is the bit I don't understand

In this section for my original cid.

x.xx.111.x - T-Mobile (DE)
modelid: 0P6B10000
cidnum: T-MOB101
1.12.111.18 -> 1.57.111.2
1.57.111.2 -> 1.70.111.1
1.70.111.1 -> 2.23.111.3
2.23.111.3 -> 3.32.111.3
3.32.111.3 -> 3.32.111.9
3.32.111.9 -> 4.19.111.2

What I dont understand is how to use these files to restore everything on my phone back to stock, As they are split into all of these files. I know these need to be flashed in stock recovery. What i dont understand is do i need to install all of them from version 1 or just flash stock recovery 3.32.111.9 and then run the last update file 3.32.111.9 -> 4.19.111.2 and then when done ota via the phone.

Can i do anything with these files such as build my own firmware.zip and just flash once straight to 4.19?

Can someone please enlighten me on what the hell i should be doing with these files. I want to completely change to a different fw but have still not secured a way of getting 100% back to stock should i need to. I have a twrp of my current fw but this does not restore things such as radio etc. I also cant find a RUU for tmob101.

You need to restore using the RUU files; if you don't find one for your device then you'll need to wait until one is available. Is there a particular reason why you want to restore to stock?

I want to change to a uk fw but dont want to do it without a way back to stock should i need to in the future, There is a twrp for 3.xx which could then be ota to 4.19. However from what ive read twrp isnt a 100% restore radios etc. So not sure whether it would work and as yet there are no RUU's for this variant. All i have is unmodified 4.xx twrp backup. But havent got any of the other stuff twrp doesnt backup. So am not to sure how to proceed if I cant get back.

What does twrp not backup?

TWRP backs up the system and data files. I can't say for sure if the radio images are backed up, but I'm going to say those are not since those are typically flashed to a different partition. Also, I would highly suggest NOT flashing radio images that were intended for another model. You could brick the phone and have no way to restore back to it's factory state.

If you are trying to use the device on another network, which is not supported by the device due to radio/hardware limitations, I would suggest selling it and obtaining the appropriate device.

So if i was to use a uk RUU it wont update the radio? What stuff does TWRP not backup?
