[solved] "internal Storage Running Out" Notification After Clean Flash

[CosmicDan]

Getting a constant nag notification "Internal Storage Running Out" only in Xiaomi.eu firmware after CLEAN flash. My settings clearly shows internal storage has ~10GB free space, but lots of things just refuse to work e.g. Play Store downloads because it thinks the device is full.

Here is how I installed the firmware:

1) Unlocked Bootloader
2) Flashed TWRP
3) Noticed that /data would not mount, so did "fastboot format userdata"
4) Installed latest Redmi Note 4 weekly firmware
5) Went through setup wizard all OK

I tried flashing China Developer ROM with MiFlash *and* SP Flash Tool and repeating the above steps to no avail. I also tried doing "Format Data" option in TWRP instead of the fastboot method. Nothing works.

I also tried to fastboot flash the stock recovery, then do a Factory Reset via the firmware, but still it's broken.

Seems to be a ROM bug, since it does not happen with official China nor Global firmware. But why has it not been reported yet? What is special about my device?

From logcat, this seems to be related:


10-04 15:09:04.088 1165 1180 D SettingsInterface: from settings cache , name = sys_storage_threshold_percentage , value = null

10-04 15:09:04.088 1165 1180 D SettingsInterface: from settings cache , name = sys_storage_threshold_max_bytes , value = null

...those values should not be null. I will try to manually insert these values into the settings.db table and see what happens.

EDIT: Injecting them worked, it reads the new default values, but it didn't solve the original problem afterall.


Anyway, here's a dump of df command (the Settings > Storage also reports correct values).

Disregard... did a Wipe Data (not Format Data) in TWRP *before* installing the firmware and it now works. Craziest thing, but whatever
