Overall, this guide is to help your Japanese S7 Edge scv33/SC-02H to look more like a standard international model.

So let’s begin.

Step 1:

All required files can be downloaded from here

https://drive.google.com/open?id=1XElzbRcvlqf1CXjGK8Oiu6rmlnAvcphY

Caution. Backup all of your personal data. This process will need you to factory reset or will erase all of your data including your personal photographs, apps, videos etc.

You will also require to have a fresh piece of sd card (16 gb or more recommended) to store the twrp nandroid backup if anything goes wrong.

So, First, you will need to remove the modifications that were made to your device stock boot image. If you have flashed the modified kernel or have rooted using super-su, then, you will need to undo all the changes. You can flash the stock boot image file only but I would recommend you to flash the whole latest firmware that you can find easily over UPDATO Firmware website to start better all over again.

Here is the link to the latest SC-02H android 7.0 firmware:

http://updato.com/firmware-archive-select-model?record=AD3D69507E2D11E7963AFA163EE8F90B

Download and extract it. You will find 5 files. You can ignore the HOME……. file. Flash the 4 firmware file using latest Odin.

After flashing, let it boot up. Finish the setup wizard and turn off the device.

Step 2:

Flash the TWRP that you downloaded from here. Download Link is same as above.

https://drive.google.com/open?id=1XElzbRcvlqf1CXjGK8Oiu6rmlnAvcphY

Twrp Bug: Device will reboot to twrp recovery if you choose to power down the phone from recovery option. You will have to choose “Reboot System” from twrp menu to solve this.

After installing, boot into twrp recovery. Go to Wipe and at the bottom right, you will have option to format data. Perform a Format data process. Then, make a TWRP backup to your sd card.

I repeat. Make a backup. This will help u a lot if anything goes wrong

Step 3:

Time to install magisk.

Extract root.zip file and there you’ll see magisk.zip

Flash this magisk installer file from twrp and reboot the device.

Install the latest magisk manager app apk.

Now your device is rooted with the latest magisk available.

Step 4:

Time to remove the bloatwares.

You will need ES file manager and System app remover from playstore.

Grant super-user access to both apps. Navigate to device/system/preloadFactoryResetOnly using es file manager and delete all the contents inside that folder.

Download the apps.zip file from here

https://drive.google.com/open?id=1XElzbRcvlqf1CXjGK8Oiu6rmlnAvcphY

Extract it to your pc. Copy all the extracted apps including their folder to your device and paste it inside the same path i.e, device/system/preloadFactoryResetOnly folder.

Important: You will need to change the copied each app file permission to RW-R-R.

You do-not need to change the folder’s permission. But you will need to change the each apk’s permission one by one. Long press on the apk and then go to properties. Tick mark on (read-write, read, read).

But there will still remain some Japanese DoCoMo bloatwares. You will not be able to remove it by simply using system app remover.

So, use the system app remover app to track down the bloatware’s location by long pressing and delete it by using es file manager. Remember, only delete the bloatwares that are found in device/system/priv-app and device/system/app folders.

Caution:

You do-not need to super trim down your system in hopes for getting more internal space or whatsoever by deleting the bloatwares that you don’t know. Just delete the DoCoMo apps that you can see in the app drawers.

So be aware.

Factory reset after the above step.

Step 5:

Now comes the last part:

CSC Tweaks:

Download the 3 modified csc files from above link. Copy and replace them to path device/system/csc

Change the copied file permission to (rw-r-r).

To change the default device language and set the sms delivery option on by default, copy the Customer.xml file to your pc and edit it by using Notepad++.

Find the line as shown as in the picture below and modify as in it. Save it and replace it back to where it was from which will be device/system/csc and change its file permission again to rw-r-r.

Now turn off your device and boot into TWRP recovery. Perform a factory reset and reboot.

You will have latest apps with all the custom changes including your default language changed to English.

No need to install magisk manager apk as it is already there in the apps.zip folder.

Done!
