Amazfit Watch 2 - TrainingPlan data lost after re-pairing - Amazfit

Hi,
need your help with TrainingPlan app.
After reinstalling Amazfit Watch app, I had to pair the phone with watch again. Don't know why but after sync, TrainingPlan app got wiped.
It's not that big of a deal, because all the activities are still recorded on the watch/mobile/strava but I was in the middle of half-marathon training plan and would like to continue it.
In order to restore/recreate this data, I need to know how exactly this app is storing it.
I have already reviewed the source code available on gitlab.com - /Neuer_User/PACEfied_AmazFit
I have also downloaded the TrainingPlan.apk directly from the watch (with adb) and decompiled it (apktools) and reviewed the app in IDE.
Here is the content of AndroidManifest.xml from TrainingPlan:
Code:

</manifest>
Still no luck.
Can anybody help?

If the data is stored in the watch only (and I think it's the case for Training app), it was wiped out when you unpaired, so there is no way to recover it.

Sure. That's understandable. Still, if I know exactly how is it stored - I could recreate it.
I saw a sqlite3 file in xbin folder. Problem is that it is encrypted and I cannot open it.
Does anyone have any idea how do those guys store data on such apps?

Ah, I see what you want to do now. See my AmazeBackup tool, it backups and restores data to the Sports app, you can use adb to backup data from TrainingPlan app, extract its db, modify the file, add the modded file to backup manually, then try to restore the file to watch (restart watch after you restore to make sure it loads the new data).

lfom - thanks a lot for the tip.
I solved it.
Biggest challenge was to identify and get the access to /data/data/com.huami.watch.train/databases/train_center.db which hold all the data.
After that happended, it was just a try and check for different values in TrainRecord and DayTrainRecord DB tables + adb pull and adb push as a root.
Still, I wonder when they would add those training plans to Amazfit Watch app and synchronize this data properly.
