Here is one possible method can save laozhang from such embarrassing situation:

You can update the Irex Official refresh update file 'cf-card-contents' to replace the power management module with which iLiadPowerManagement-0_90.zip provided.

iLiadPowerManagement-0_90.zip is using voltage to measure battery capacity, maybe that will resolve the problem of battery icon blank. Hope so.

The Iliad application file system in refresh package is compressed into file 'app.image.gz'. After you uncompress this zipped file, the file 'app.image' is the whole thing you need to update.

The file 'app.image' actually is the linux file system image, it is the standard linux ext2 file system. Finally you can used linux tool to update the whole system you like, even you can update to the last version 2.12.

Just a hint for your reference!
