Xiaomi Redmi Note 4 - Install problems

[gecc0]

Hi everyone,

I have some problems activating rSAP on my Xiaomi Redmi Note 4X (Snapdragon 615, rooted).

last week i was able to install all needed system files (Generic MK.III), but i got the "QMI_ERR_ACCESS_DENIED" Message.
After that i tried all QPST and QXDM steps. I was also able to upload the "sap_security_restictions" file after setting the phone in test mode.
Unfortunatly, everything didn't worked. i still got the same error.

Today i received the official update of MIUI Global 8.5 containing Android 7.0. I thought it was worth a try again.

I'm able to install the system files without any error (all 3 check marks are green). but after the auto reboot only the first point is ok.
(V) - System Files Installed
(X) - Connect to Socket
(X) - Connect to SIM

I installed/uninstalled the system files a few times (tried MK.II and MK.III but only MK.III works). Tried to install it with recovery installation. Factory reseted the phone (including internal storage), but nothing works.

I didn't found any similar topic, thats why i created a new one.
I hope you could help me with this. My old HTC One M9 is dying and i need another rSAP capable phone.

Thank you in advance.

I've already done each step of this howto befor the update to Android Version 7.0 (MIUI 8.5), without any success.
Did you also got the same error on the app?

I have same behavior with Redmi 3s using ResurrectionRemix 5.8.4 Android 7.1.2.

I did all the magic with QPST / QXDM. Needed to enable factory test mode to upload sap_security_restrictions file.

Then verification shows all Ok when installing MK.III, and 2 errors after a reboot.

Well, it works finally. You don't need to install drivers or launch rsap app after applying QPST fix. It works by itself then.
