[ZTE Nubia Z17 Mini Questions & Answers] kid1er:
Hello every,

I would like to start by saything that I don't usually post on forums since I'll always search for hours on the internet.

I do find a solution after different atempts. But this time, absolutly nothing worked.

Nubia Z17 Mini NX569J (AArch64)

Marshmallow - Stock ROM (bought on Gearbest)

Rooted with lastest TWRP (3.2.1)

What happened : I tried to install the Xposed framework.

1/ Made a backup using TWRP containing every option I could check

2/ Installed the v86 framework from Xposed instead of the v89. It worked anyway.

3/ Back to my phone, I installed the Xposed App. Framework was detected successfully.

4/ I downloaded different framework from the App (Block Youtube Ads, Soundcloud Ads, Soundcloud downloader, Battery saving stuff...) and rebooted my phone.

5/ Long reboot time and stuck on a black screen.

6/ After many attemps, I went to TWRP and used my back-up. Everything was back to normal.

But ow, When I'm trying to install the v86 or v89 zip file from Xposed, I get this error :

Zip signature verification failed!
Error installing zip file '/sdcard/Download/xposed-v89-sd23-arm64.zip'

Without zip verification :

Installing zip file '/sdcard/Download/xposed-v89-sd23-arm64.zip'

What I tried so far :

-> TWRP is NOT on Read Only. The box in unchecked and I could use it to install SuperSU zip file.

-> Reinstalling TWRP

-> Reinstallling SuperSU

-> From ADB :

C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell
shell@NX569J:/ $ su root
root@NX569J:/ # mount -o rw,remount /system
mount: Read-only file system
-o rw,remount -t yaffs2 /dev/block/mtdblock3 /system <

mount: Read-only file system
255|root@NX569J:/ # mount -o remount,rw /system

With Xposed Installer :

chown: /system/bin/dex2oat.orig.gz: Read-only file system
Error 1 occured

Uninstall with Xposed Installer :

rm: can't remove '/system/xposed.prop : Read-Only file system
can't remove 'system/framework/XposedBridge.jar' : Read-only file system
rm: can't remove 'system/bin/app_process32' : Read-only file system
mv: can't rename '/system/bin/
app_process32_original': Read-only file system
Error 1 occured

Root Explorer : nothing happen when I click on "Mount as R/W".

Android Terminal app :

[B]root@android:/# mount -o rw, remount /dev/block/system
mount: Read-only file system[/B]

I tried with Busybox too but it's the same problem : system is Read Only

Soooo here it is. I don't have any idea now. I backup up a few times but nothing change.

I was thinking about chaging for anothing ROM but I'm afraid about loosing battery life. And I don't want all of my applications again.

What do you think ? :)
