[Q] Debranding softbank 201HW
I recently bought the softbank Japan version of Huawei Ascend P1 LTE ---> (Rebranded by softbank Japan as softbank 201hw)
I want to debrand it and convert it back to Huawei Ascend P1 LTE. Basically I want to dump the softbank firmware on this device and flash the stock firmware from Huawei.
Would be grateful if someone can someone help me to get clarification on the below queries.
1) Do I need to root my device to flash the Huawei stock firmware ?
2) I managed to get the system.img, recovery.img and boot.img files for the Huawei stock firmware.
Are these files enough for flashing the firmware. Are any other files needed in addition to these
