Encrypt phone

Doesn't seem to be working for me. Has anyone else tried?
Hi everyone,
same issue, it doesn't work for me either.
When i run security -> encrypt phone i can see the Android logo for a few seconds, then the phone reboots.
My curent device is Redmi Note 3 Pro (Kenzo)
Build i 13.0-20160910-NIGHTLY-kenzo
Would be great to have a solution or work around.
Thanks,

Miui 8 & bt

I have Xiomi Redmi Note 2 and one of it’s major uses is phone calls while I’m driving- speaking via my BlueTooth car kit.
With the new MIUI 8, I have a problem: At the end of the call, I used to disconnect by pressing the “disconnect” button on my car BT device. Now, with the MIUI 8 it simply doesn’t work- the “disconnect” button doesn’t ends the call and I have to tap on the device (very dangerous while driving).
I made factory reset to see if there is some conflict in apps- the problem remain.
I downgraded to MIUI 7.5- the problem remain.
I downgraded to MIUI 7.2.3- and the BT returned to work properly.
I upgraded with the internal “update” app- the problem came back...
So, seems like that somewhere between 7.2 and 7.5 a change was made that made damage to the BT car kit connectivity.
1- What happened?
2- How can I solve it? Should I stay with MIUI 7.2.3
other ideas?
thanks
I didn't have bluetooth issues with 7.5 or 8.0.x - but such problems may be due to the modem drivers. Which modem driver does you 7.2.3.0 come with? Look in for "Baseband version" in "Settings->About phone". My version of 7.2.3.0 comes with modem p37, which is very good for bluetooth. If yours is p37 as well, that may explain why you don't have any problem when using 7.2.3.0.
PS: I eventually reverted from 7.5.x and 8.0.x to 7.2.3.0, because I couldn't see any benefit from the later versions, which are also more resource hungry.
in miui 7.2.3 I have p51 and it's working well
suppose that's the problem with miui 8
how can i changer the modem?

IIRC, miui 8 also comes with p51, so that may not be the problem.
As for how to change the modem, there are links to installers for various versions in the Redmi Note 2 forums (including, I believe, p52). You will have to do a general search (e.g., for p37, p48, p52).
Here is a link to installers for various RN2 modems: https://mega.nz/#F!qwdklTTT!PvPmCdshrIf0UgQMKEAV6w

Wifi 5 GHz hidden

Hi guys. I have a problem with my mi pad 4. I have a problem with the 5 GHz wifi that is no longer displayed in the networks available with rom pie. let me explain. with the RoM 10 MiU the wifi networks 5 are perfectly detected. I installed the ROM pie (AEX havoc). the 5 GHz wifi appeared good at the beginning. then for some unknown reason I was disconnected from the 5 GHz network. resettlement. network reset ... flash rom pie I can not see any 5 GHz wifi network anymore. I reinstall a rom MIU in 8.1 global wifi is present. the problem is under the rom pie. if you have any solutions please ?

thank's. I need to edit the wificountrycode file with the value 0 with a app type file manager root (ex solid explorer)?
Issue resolved with the latest version of Havoc.

thanks to dev. This is the only Pie ROM that does not have this problem in wifi alone without a SIM card.
Right, because the needed change which I referred to is included in this version.
Changing the "control channel" on the router fixed it for me. I suppose this the workaround. The fix is in that wificountrycode parameter.

MIUI 12 bluetooth issues with car infotainment and continuous disconnections

Hello everybody,
I own a Xiaomi MI 10 with the latest stable MIUI 12 EU ROM,
since I did the update from MIUI 11 I am having problems in pairing the phone with the VW e-UP infotaiment system (called Composition Phone).
In practice, once paired after a few seconds it uncouples and then after a while retry a new pairing which after another few seconds it disconnects and so on ..
I tried all the developer settings a bit but they didn't help.
I also noticed that going to the bluetooth devices of the phone, if I tap on the name of the infotainmet just before the automatic procedure starts, then the pairing is successful and no longer disconnects.
Anyone have the same problem with a VW? is there a solution? I also installed Magisk, is it possible to patch the bluetooth libraries?
Same exact machine and exact same problem.
You Found solution?
I am waiting for xiaomi to give me the code to unlock the bootloader and I will go back to the UMIGlobal_V12.0.1.0.QJBMIXM which worked perfectly for me.

Great! it's nice to know you're not alone where are you from?
I can tell you that I tried the latest EU ROM and it didn't work, but the EU compared to the global one has several nice features more. Since you have to unlock I advise you not to put the global again.
Before downgrading I would like to try the ROM EU weekly which if I have not misunderstood is based on the MIUI 12.5 beta, but for the moment I have not yet done so ..

Even the weekly does not work
I finally managed to solve the problem with the ROM
xiaomi.eu_multi_MI10_V12.0.8.0.QJBCNXM_v12-10.zip
which also works very well .. In any case I begin to think that it does not depend on the MIUI version, but on the version of android. I think the bluetooth management problems are due to android 11.
A bit late but have you tried changing the Bluetooth protocols in developer settings? You can change the version etc..
I have a new e-UP since yesterday.. same problem here with MIUI 12.5.1.0 on Poco F3.
Any solution without downgrading the rom? (MIUI 12.0.5.0 is also Android 11 on F3)
I think i will go for a Custom Rom in the next few days..
Does the latest Maps+More update changes anything? It says "Android 11 compatibility"..
HI Guys,
For me this problem is still alive. I'm running a VW E-Up also and since updating to MIUI 12 my car bluetooth is unusable as it constantly connects and disconnects to my M10 every 5 seconds or so. I've experimented with many settings changes, along with unpairing and re pairing but all to no avail.
I'm running 'Maps and More' ver 5.0.0 also but it's useless as I can't stay connected long enough to do anything with it.
Has anyone found a fix without downgrading?
Same problem here... any news/solution?

Hi guys,
I have similar issue since version later than 12.5.3. I even changed my phone to other xiaomi model, the issue remains.
So I will flash back to 12.5.3 if the issue cannot be solved in 3 months...
Now I have to turn on and off airplane mode to temporarily solve the issue every time I need to use Bluetooth related functions.

Hy folks,
Idk if the Bluetooth is the same but I got the skoda citigo with the Garmin device. Had the same issue. The resolution for me was to activate developpers options and change the Bluetooth Codecs to what my GPS device supports as it was way older than the one build in my redmi note 11
My perfect solution: I deactivated the work profile, and eveything is fine again!
