Clean stall procedure via TWRP âInstallâ uncomplicated; e-System starts properly and can be set up. WLAN / Wi-Fi is recognized immediately and works. Further tests laterâŚ
Short note: My previously unknown issue occurs in connection with the e-Browser v131.0.6778.140
When entering the characters . (= dot), e.g. e.foundation or slash (â/â ) in the URL search field, the entire content in the search field is deleted. This means that e.foundation cannot be typed in completely and the URL cannot be called up. The alternatively installed FOSS Browers from the F-Droid Store, on the other hand, does not have this problem and works perfectly.
So nice, thank you @ronnz98 !
Yes, itâs working fine. Itâs mandatory to work with the latest Twrp or OFox recoverys to make it happen. Earlier recoveryâs will fail I assumeâŚ
Also no .dot or /slash problems with the e.browser hereâŚ
Thanks a lotâŚ
No, GPS is running fine including GPS fixâŚ
PS: How do you tested it? I often use FOSS App âGPSTestâ or âGPS CockpitââŚ
I used Statsat and GPSTest from Fdroid.
Will try your recommandations, thanks !
Edit: same, it âseesâ some sats but not able to âfixâ its position. Any advice ?
You can try GPS Cockpit⌠I think, itâs more precise in recognizing all satâs and fix them more quickly than GPSTest doâŚ
If this does not work, my only tipp would be, going back to latest stock rom version to make sure, that uâre using latest firmware versions for the midoâŚ
PS: But donât forget about the switch in âmiflash toolâ to leave the bootloader open before reflashing⌠
Good luck
Thanks @Pete1, already did all your reco: back to n and n-1 original firmware: I was able to get imei back, wifi and bluetooth mac adress too but no luck with gps.
Were able and OK to send me your qcn file, I promise to not mess with your imei (as I saved mine and already injected it in a âcleanâ qcn) ?
If your imei, wifi and mac addresses get lost when you go back to miui Stock, than something went really wrong with ure hardware, i think :-))
PS: I do not know much about QCN backup and restore. Maybe because I never lost the physical hardware addresses while flash back to stock or similar. Also, I think it is not the best idea to share these infos with someone I donât know.
But may be you can find more info about Note 4x QCN here > All Xiaomi Phone QCN Backup Files â Xiaomi Tools
Beside that I think that the GPS system have nothing to do with QCN. Maybe there is a problem with your gps.conf file?
Greetâs
Sure @Pete1 youâre right, understood.
I get a qcn from xiaomitools but itâs from a mido 201604 model, mine is 2016102.
Here is its trip: stock FW â Lineage â postmarketOS â /e/
Perhaps postmarket erased something ⌠@piero is it possible ?
Where did you install postmarketOS ?
/system ? /data ? /external_sd ?
not /external-sd but i donât remember /system or /data.
Any clue ?
If Reinstalling stock software without relocking the bootloader is possible, it could be a wayâŚ
Sure itâs possible, but I already did it twice or more before /e.
And after PostmarketOS ?
Yes after postmarketOS
Cheers, @ronnz98 for your work keeping mido alive! 
Any ideas? (The App-Lounge has to be updated in order to update other apps but canât due to a signature error. Plus the anonymous access does not work.)
As far as I remember concerning the fingerprint reader there are different ones build in (Goodix and ?).
Has anyone managed to fix a non-working fingerprint reader?
Cheers again for your work (I just reactivated an almost forgotten mido yesterday)!
