Step 1: Check Chip Type

Connect your phone using ISP and check the chip name.
If it matches one from the list above, you’re good to go.

Step 2: Backup Everything

Before making any changes, back up NVDATA and NVRAM.
These files store your IMEI and security info.
A simple backup can save you if anything goes wrong later.

Step 3: Set RPMB Counter to 0 (16MB Method)

Now you need to make the RPMB counter 0 using the 16MB method.
If you don’t know how to do it, there’s a tutorial video available — just follow that.

This step helps unlock IMEI write protection on some chips.

Step 4: Flash the Full Firmware

Next, flash the official firmware.
When flashing, uncheck the “Userdata” option.

Once flashing is done, a message will appear saying:
“Format Userdata as F2FS?”
Click Yes.

If the phone restarts again and again or gets stuck on the logo, just enter Recovery Mode and do an update via Wi-Fi.If you see any error while flashing, simply reboot the device and try again.

Step 5: Check IMEI Status

After flashing, set up the phone normally.

Then dial

— it should show 0000000000000 as the IMEI.
That means the device is clean and ready for IMEI repair.

Step 6: Patch NVDATA & NVRAM

Now open Scorpion Tool on your computer.
Load your NVDATA and NVRAM backups, and patch them with your original IMEI numbers.
Once done, connect the phone again using ISP.

Step 7: Write Back Only NVDATA

Now write only the NVDATA file back to the phone.
⚠️ Do not write NVRAM.
Writing NVRAM may break the SIM network or cause errors.

Step 8: Final Check

After writing NVDATA, disconnect ISP and turn on the phone.

Check both SIMs again using
