UMIDIGI G9x V1.0_20250918 ROM - SPD release

bencebacsi

This is the SPD Flash Tool release of the
V1.0_20250918 system software
for UMIDIGI G9x


Flash tool operation is recommended to experienced users only. If you are not yet an experienced flash tool user, please carefully read the SPD flash tool tutorial before proceeding, and strictly follow each instruction.

Except if an authorized or responsible expert directly asked you to do that,
never format the flash chip of your device or you instantly lose your warranty!


UMIDIGI G9x receives all updates automatically via FOTA method. You need this tool only in case of emergency (if you've bricked your phone), if you want to apply a clean install or if you want to clear all root access and custom recovery to make your phone able to receive FOTA updates again. Moreover, flashing with an SPD flasher is the only option to repair (replace) damaged system software.

Kind request from users:
Please report any kind of new issues you experience after installing this update only if you've already flashed this ROM with an SPD Flasher. In rare cases a FOTA update can cause more or less serious malfunctions but that means only the update process went wrong, not a badly developed ROM. An updated stock ROM, especially related to the basic functions will not cause any new issues but will solve some of the existing ones.

The safest way to update your UMIDIGI G9x is through the automatic FOTA method, as it doesn’t risk wiping your warranty or damaging the system. The SPD Flash Tool should only be used if the phone is bricked, needs a clean install, or you want to remove root/custom recovery. If you must flash, carefully follow the SPD tutorial, install the required drivers, and use the correct .pac file. Never format the flash chip unless an expert specifically tells you to, since it can permanently damage your device.
