About ROM

 

This ROM helps Zawgyi users move to Unicode. Plus, Unicode users will be able to see Zawgyi because the ROM detects Zawgyi and convert it to Unicode. After being converted, the original text is also added below followed by "========" just like in the photo.

Download iRoot and install it on your phone. You will see Root now button in the app. Tap it and tap grant if it asks for permission. Now, your phone is rooted.

3. Backup your user data

Copy all your files from internal sdcard to your computer.

4. Backup NVRAM

 

Why backup nvram? After installing ROM, your phone will lose NVRAM. Without NVRAM, you cannot make phone call or use mobile data. You need to backup NVRAM before you proceed so that you can restore it back. Please, refer to this link for backuping up NVRAM.

5. Unlock bootloader

 

If your phone is china variant, your bootloader is already unlocked. If not, you need to unlock it before you proceed. With locked bootloader, you cannot install ROM easily. So, follow these steps to unlock your bootloader: ( these steps are copied from this site and edited )

• Download Honor3CBootUnlock.zip on the computer and unzip it too.
• Download Tools.zip, unzip it and look for SPFlashTool folder.
• In SPFlashTool, you will find FlashTool.exe. Right click on it and choose run as administrator

• Set Memory Setting to EMMC, Beginning Address to 0x800 and Container Length to 0x1B0EC. Finally click Write Memory button.
• FlashTool is waiting for connection, now connect your phone to computer using USB cable, WITHOUT the battery inserted. I repeat. WITHOUT the battery inserted. 
• When Flashtool has successfully established a connection with the phone, the writing process will begin.
• GREEN circle will be displayed if the writing succeeded.
• Now DISCONNECT the USB cable from your phone.
• Go to Download tab and make sure you’ve disconnected the USB cable. Check DA DL All With Check Sum option. Then, press the Download button. 
• A Download Warning message should pop up, click Yes.
• Reconnect your phone to computer using USB cable, WITHOUT the battery inserted. Wait for a few minutes until it gets completed.
• GREEN circle will be displayed if the writing succeeded just like before.
• Now DISCONNECT the USB cable from your phone.
• Do not close your FlashTool and do not insert your battery yet. we need it in the next step.

6. Make Nandroid backup

 

Nandroid backup means the whole backup of your phone. Why nandroid backup? just in case you might break your phone. Follow these steps to make nandroid backup: ( This tutorial is referenced from a xda thread I described earlier at the first stage )

• Edit the read back settings as following: ( Type: Hex, Start Address: 0x0, Length: 0x62380000), then click OK

• The processed files will be saved in OUTPUT folder.
• After that, I suggest you take a break for about 30 minutes. Your phone may really hot right now.
