[Redmi K20 / Xiaomi Mi 9T Questions & Answers] zgfg:
I'm using Xiaomi.eu (latest 12.20.20) but problem began a month ago with 20.4.28 and IMO, must be something generic about MIUI and its Updater app - Settings / My device / Updater)

Does anybody know where the Updater stores (unsuccessful) downloads and/or anything about the available updates (excepts on root of Internal memory and the Updater's folder in /data/data aka /data/user/0)

I have Magisk/root (and MiXplorer) and TWRP, hence I could delete wherever I would need..

Problem:

- Opening System or System, My Device, they note me that some update is available (screenshots 1,2).

- However, I have the latest Xiaomi.eu 12.5.20 hence there is no (and there will be no) update until 21.5.27 Thursday next week.

- And indeed, once I enter Updater and I Check for update, it reports that I'm up-to-date, i e., that there is no update for me (screenshot 3).

When I ran Security app, it reported me that (a month old) 21.4.28 is available - I'm not sure but maybe a month ago I really tried downloading 21.4.28 (when it was brand new) from Updater and it failed but then I deleted the broken zip file and the accompanying mdf5 file from the root on Internal memory.

But maybe, something/somewhere remained on the phone making it to think that an update is still available.

I already did/tried but no avail:

- Clear Cache and All data for the Updater app from Settings, Apps

- Wiped Dalwik and Cache from TWRP

- Wiped /data/system/package_cache

- Manually deleted /data/data/com.android.updater (data folder for the Updater app).

- Also, I have inspected Internal memory (files and folders on root and also /Android/data folder) and /data partition (by browsing with MiXplorer as much as it made sense) but I could nowhere find anything to look like related to updates.

- I also opened Downloads app and deleted everything it showed me for (the old) downloads.

- My /data/ota folder is empty.

- I did deep cleaning from Security app, no avail - it still notes me in Settings and My Device about some not-available (Xiaomi.eu) update.

It makes me crazy because downloading Xiaomi eu update by Updater app was a way faster than manually downloading Xiaomi.eu zip ROM by browser (even ADM) from AFH or from SFN servers.

Plus, Updater downloads both the zip and md5 files.

It's also more convenient (when it works properly), it should show when update is really available, just like for OTA, hence I would not need to check every hour on Xiaomi.eu forum or Telegram when update becomes available, to take the AFH or SFN links there to manually download...

Last Thursday when I was on 21.5.12 and Xiaomi.eu 21.5.20 really became available, Settings and My device were showing that Update was available (as they constantly do) but the Updater was answering that I was up-to-date / that there was no update for me - hence all the same as now upon I nanually updated to the latest Xiaomi.eu - and thus I was unable to use the Updater to really know when update was available and to download it

I can live with that problem (and manually update the new Xiaomi.eu next Thursday, and so on) but I would really like to solve the problem.

I want to know what exactly to delete to get rid of -however, I will absolutely NOT GO into Wiping (or even Formatting) Internal memory or Data (like Factory reset) since everything else works perfect (and the phone is my daily driver)
