My note 10 firmwear changed

[mazen othman]

I have a Galaxy Notee 10plus sm - 975U a spectrum remembere when I bough it the firmware was sm-975U1 afterot OTA softwar update it change to N975U .

Idon't know much about bootloader and unlocking it but I think that it is unlocked cuz iam living in yemen and the sim card that iam using is cdma and the phone work fine with it

iam wondering if it possible to flash a U1 firmware ( the universal one) and how to check if the bootloader is unlocked or not

Hi, welcome to AC!

Software updates dont change firmware , it would have to be done through odin .

Download to you pc from xda website
Frija tool
Odin prince comsey [patched 3b ]

Extract the frija and odin zip then in frija put model number for unlocked region XAA and download to pc after put the 4 firmware file after you extract them in corresponding slots in odin.

Put the device in download mode and dont interrupt the flash process until it says pass
