  • Backup modem partitions (md1img_a, nvcfg, nvdata, nvram)
  • Flash USA or Stock modem configurations from your backups on the fly

Installation

Download Module

  1. Flash module
  2. Reboot device
  3. Access via WebUI (KSU WebUI or MMRL)

Usage

  • Choose USA or Stock folder for backups
  • Flash either configuration

This module expects .img partitions. Just change the extension of your backups when placing in either USA or Stock folder.

Does this write an imei also?

4

No, this just flashes or backups of your already written partitions.

Can go back and forth when you travel. USA or Stock.

5

Is there an app that writes imeis

6

Not that I’m aware of. Would be different for every phone. I tried making one for the f21 pro and wasn’t successful (yet?).

7

Super cool but it doesn’t really work when switching between networks I don’t have any service connection

8

Don’t understand what you are saying

9

When I switch between US bands and stock I don’t have any service

10

Are you in the US? That would be the reason

11

Yes but when I switch back to US bands I still don’t have service

12

Did you backup your partitions before? YOUR partitions, not the xda f30 bands with generic info.

13

Yup

14

Weird. Worked for me, I’ll have to try again. All my info is there too in the about phone page.

What happens when you reboot? Nothing? No sim showing up?

Is your info showing up in about phone?

15

@Samtee-1 I’m not denying your experience. I will say though that I just tried it again and it works fine.

16

Interesting. Well thanks anyway
