How to remove Chinese from Galaxy A9 Pro A9100

Chinese Galaxy A9 Pro has the model number A9100. If you manage to get your hands on this device while you are not a Chinese citizen, you will highly unlike what you will see on the screen. The phone is all Chinese. It has the Chinese language set on it. It has Chinese bloatware on it and you will find that junk everywhere in the phone. The very first thing you would want to do this phone is to change the language, but you will realise this within no time that there is no such option to change language on the phone.

This situation leaves you with no choice but to customise the phone and get rid of that junk. A custom recovery for the Galaxy A9 Pro A9100 was released a few months ago. The phone was rooted as well. This made it possible to flash differnet files on the phone and tweak it. Right now, you can kick out all the Chinese junk from the phone and debrand it to make it a normal phone by following a little procedure.

Once you are all set, you can flash a CSC file for your region or for your city. After flashing the CSC file, you have to flash the relevant GPS.conf file on the phone and that’s it. You will have the phone unbranded and you will be able to set English language or any other language depending on your liking.

  4. Now click on the “AP” tab in Odin and select the TWRP Recovery.img.tar file according to your device carefully.
  5. The options ticked in Odin should be only “F.Reset Time“. Make sure that the Auto-Reboot option is not checked, we do not want to reboot the phone after flashing TWRP recovery.

  9. TWRP will ask you whether you want to allow modifications or not, you will need to swipe finger to the right to enable modifications. Swiping the finger to right will trigger dm-verity, if you will need to disable it immediately. Leaving it enabled will not let you boot the phone neither root it. This is an important stuff since we want to be able to modify the system.
  10. Now tap “Wipe > Format Data > type “yes” to format data. This is important to disable encryption. This step will factory reset your phone, so make sure that you’ve backed up the entire data at hand.
  11. Now make sure that you’ve copied the SuperSU.zip and dm-verity.zip files in external SD Card or USB OTG, if not then transfer both these files to your external SD Card by using MTP mode in TWRP now.
  12. Once you’ve the files, tap “Install > Install Zip > locate the SuperSU.zip according to the location where you copied > flash it”.
  13. Now once again tap “Install > Install Zip > locate the dm-verity.zip file > select it > swipe to flash”.
  14. Get back to main menu in TWRP recovery, tap Install > Install Zip > Locate CSC.zip file > select it > swipe to flash.
  15. After flashing CSC file, go to the main menu in TWRP for the last time, tap  Install > Install Zip > Locate GPS.conf file > select it > swipe to flash.
  16. Once done flashing, reboot your phone to system.

    Hey, first-off thanks for such a detailed step by step post.

    I followed all the steps diligently, but I seem to have been stuck on the last one. My Samsung SM 9100 is not coming out of the TWRP recovery mode – the “reboot to system” is starting the recovery mode again, so I’m stuck in a loop.

    Please help.

    • @disqus_XcxAdelsMU:disqus Did you format data/factory reset the device and flash the dm-verity file?

      • Dave Lumawig

        same issue here

        • @davelumawig:disqus Did you format the data after entering the recovery and also flashed DM Verity + Root file?

  • Sameer Memon

    How can a firmware file has 420 kb size?

    • @disqus_V9iMev7bhR:disqus You’re probably downloading some invalid file. The firmware filed linked above is proper and of full size.
