[Guide] Switching OEMINFO versions

[sykomaniac]

I've seen a number of posts asking how to switch the oeminfo of your phone - so I decided to make a quick guide.

Warning: Use this guide at your own risk. I did this on my own p20 Lite without issue but YMMV.​

Pre-req's

• Please ensure that you actually have an unlocked boot-loader
• Ensure that you still have access to your boot-loader code as switching the oeminfo partition caused my phone's boot-loader to become re-locked
• You are rooted
• You have enabled USB debugging and your device is detected by adb/fastboot (run

  adb devices

  or

  fastboot devices

  to check this)
• Make a backup of your current oeminfo - this can be shared on this thread for other users (in-case they haven't done this) or for your own piece of mind. You can use Partitions Backup from the Play Store, TWRP etc.
• After switching my oeminfo I used the stock recovery to perform a factory reset. I'm not sure this was required but remote backing up of files is probably recommended just in-case...

Getting Ready

To check your current oeminfo run the following command from an ADB shell:

getprop ro.hw.custPath

This should return something like this:

/cust/ee/gb

This was what my oeminfo partition was prior to installing the generic European single sim oeminfo.

Similarly, you can run the following fastboot command to check your current oeminfo:

fastboot getvar vendorcountry

Which will report something like the following:

vendorcountry: ee/gb

The Good Stuff

Assuming you have followed the pre-req steps (you have been warned!) Do the following:

• Download one of the attached oeminfo zips. Choose either single or double sim depending on your device!
• Extract the contents of the download zip to your phone e.g. /sdcard/Download (change the location as required in the subsequent commands)
• Run

  adb shell

• Enter

  su

  to gain root access
• Overwrite your devices oeminfo using

  dd if=/sdcard/Download/oeminfo.img of=/dev/block/platform/hi_mci.0/by-name/oeminfo

Now What?

When I ran the above my boot-loader became re-locked. To unlock the boot-loader you must have your boot-loader unlock code!. To unlock the boot-loader do the following:
[*]Reboot to fastboot
[*]Run

fastboot oem unlock <your bootloader code>

[*]I then performed a factory reset with the stock recovery
[/LIST]


Verifying

To check your new oeminfo run the following command from an ADB shell:

getprop ro.hw.custPath

This should now return something like this:

/cust/hw/eu

Similarly, you can run the following fastboot command to check your oeminfo:

fastboot getvar vendorcountry

Which will report something like the following:

vendorcountry: hw/eu

sorry again a question then to install a new firmware that of c432 how should I do? thanks

 

[sykomaniac]

I use hrupdate tool and flash full firmware through twrp. Ota updates also should work. You can find firmwares using firmware finder on the play store

My translation + translated by Cambridge Online Dictionary:
"Can you not specify any better? It is not understood the method, also I have a zip of the c605 oeminfo I flashed from the twrp, now do you think that it could be done one as well as this one? Would be easier if I upload the file so you can analyze it."

It is an English only forum please be sure of that.
