[mac-duff]

Hi,
having the same feature with MIUI 8.2 - 7.1.5 Beta and SuperSU 2.79 (

 

[JeeHaa]

Same here, latest weekly does not solve it, neither does SR2-SuperSU-v2.79-SR2-20170103215521.

The buildprop changes do not work for me either, and I can't install the PHH Superuser app from playstore (just keeps " Installing")...

 

[blackbile]

Here is my solution for my Redmi 4A, it works till I don't try adb communication:

/system/build.prop with root explorer

Change this:
#Set composition for USB,add xuchao,solve bug204352
persist.sys.usb.config=diag,serial_smd,rmnet_qti_bam,adb

TO:
#Set composition for USB,add xuchao,solve bug204352
#persist.sys.usb.config=diag,serial_smd,rmnet_qti_bam,adb

Plus add these lines:
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb

Let's try it guys... maybe helps you.

*************** Although
there is bug in the settings.apk "Select USB Configuration" when I change the modes, the actual will not the same as I selected.

 

[JeeHaa]

Thanks, but that still does not fix it for me.

 

[blackbile]

Sorry.

 

[JeeHaa]

I ended up wiping and installing the latest ROM from scratch, installed SuperSU 2.79 + Xposed, restored my apps using TB and it works for now.

 

[blackbile]

Grat!
How did you intall the rom - from cwm?

 

[JeeHaa]

From TWRP, as usual. Effectively just a factory reset.

 

[Prequal]

I ended up wiping and installing the latest ROM from scratch, installed SuperSU 2.79 + Xposed, restored my apps using TB and it works for now.

Can I ask which Xposed you installed? I've just updated to the latest weekly now but I had a lot of trouble with Xposed. "Installed but not activated"

Just want to make sure I'm using the correct one.

 

[JeeHaa]

No problems with this one:
xposed-v87-sdk23-arm64-MIUI-edition-by-SolarWarez-20161126.zip

 

[driver_sl]

I resolved the problem with MTP after rooting in this way:

 

[dzenk]

Thanks driver_sl (slovenija?), this worked for me.
But I also had to add the two upper lines since they didn't exist in my build.prop .
I just wrote the 5 lines at the end of the file.

On the other hand installing Superuser didn't help.

 

[still_no_name]

It's pretty weird. No matter to which numbers I change the two upper lines, it fixes the issue for me, but only temporary.

 

[dzenk]

What do you mean with temporary? It doesn't work after the reboot?
I changed the build.prop and rebooted the phone. Now it works (I connected the PC about 5 times since).

Update:
I just rebooted the phone again just for the test... And you are right, I cannot connect the phone.

Just for the info, I'm on the official international rom (not on xiaomi.eu). Sorry to tell, the slovenian language is not included.

 

[still_no_name]

Yup, it's weird. As soon as I change the build prop, it fixes the problem, after 1 reboot it's still working and after 2-3 it stops.

 

[driver_sl]

Thanks driver_sl (slovenija?),.

Bulgaria SL is for my city Sliven.
Glad I helped you!

 

[lucainno]

For my works with added line:
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb

 

[dzenk]

Lucainnno, please report if it still works after few reboots.

Two days after I added those lines I left the phone to run out of the battery. But I was not able to start it again.
Luckily I could enter recovery. But wiping data, cache and other didn't help.
I had to reinstall the rom... I made a twrp backup after that at once .

I am searching in different forums, but I couldn't find any fix until now. Maybe our russian friends at 4pda have something, but I am not so strong with that language...

 

[giouncino]

Using supersu 2.79 SR3 this problem is now fixed for my device.
I'm on 7.1.19 ROM

 

[dzenk]

Unfortunately the new SuperSU doesn't solve the problem on the global official rom. I've heard that the new eu roms (like yours giouncino) should solve the problems. But I will probably stick to the official.
Maybe there is a developer who will be able to compare the both bootloaders and see the difference that cause problems on the older eu and official miui roms - and prepare a patch that would solve it.

 

[giouncino]

In my case I saw that also on ROM 7.1.12 with supersu 2.79 SR3, MTP worked fine.
Did you enable developer options?

 

[dzenk]

Yes the developer options were enabled all of the time (with USB debuging on). Do you have a specific setting in mind?

 

[giouncino]

No, nothing special, just usb debugging on.
So probably the solution is a combination of rom 7.1.19 + supersu 2.79 sr3.

Did you try to disable usb debug and re-enable again, all done when the phone is connected to the PC?
