UMIDIGI G100A E_V1.0_20250609 ROM - SPD release

bencebacsi

This is the SPD Flash Tool release of the
E_V1.0_20250609 system software
for UMIDIGI G100A

European version for EEA countries


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 G100A 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.

Changelog:

• Minor bug fixes and system optimization

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

This is clearly meant for advanced users, and the warning about using the SPD Flash Tool is important. Flashing can fix bricked devices or restore stock firmware, but it also carries real risks if someone doesn’t follow the steps properly.

Good that FOTA is still the default for normal users — most people shouldn’t need to touch manual flashing unless something goes seriously wrong. The reminder about not formatting the flash chip is also critical since that can void warranty instantly.

Overall, feels like a standard maintenance release with minor fixes rather than a major update.
