[Xiaomi Mi 4i] kumbar55:
Download CM13 ROM, 6.6.10 FIRMWARE and PICO GAPPS.

First backup previous ROM.

Now go to recovery.

First clear data,cache,system and dalvik cache.

Now Flash CM13 ROM

after that flash GAPPS.

then flash 6.6.10 FIRMWARE patch.

Reboot.

It may take 5-10 mins time.

After that you ll be booted into cm13.

Any helps
[Xiaomi Mi 4i] ashwaniv:
You can flash it over 6.6.10 also but I would suggest to go with 5.6.11. Otherwise, you may get random screen shutdowns. I am sharing my personal experience.

Simple steps are:

Activate developer option and activate USB debugging in MIUI7.

Then root the phone using Mi toolkit (there is a separate thread for this in the Mi4i development). Also install TWRP recovery using same.

Flash the ROM and flash Gapps. Ensure to use correct Gapps (Arm64, Android 6.0).

Wipe catch and dalvik catch.

Reboot.

---------- Post added at 10:14 AM ---------- Previous post was at 10:02 AM ----------

I don't think all these problems are related to the ROM. Network is very stable.

It might be related to flash procedure. You need to do clean install and base should be 5.6.11. Also, I hope you are using correct Gapps. (Arm64, Android 6.0).

Clear cache and dalvik cache after flashing the ROM and Gapps and then only reboot.

[Xiaomi Mi 4i] arkaguha:
Need a little help.

At the first instance I flashed the ROM only and all the functionalities were working just fine. The ROM is snappy, good memory management and responsive.

Then when I reflashed the ROM with gapps (arm64 nano), I am unable to use 3G on the SIM 1. I tried to find a solution in the thread but in vain.

So if anyone could tell me where I went wrong, that would be great!

Flashing procedure maybe?

EDIT : Fixed. I did a clean flash of the ROM with gapps pico and now it works fine.
[Xiaomi Mi 4i] elot01:
I also have had this problem, but someone gave the right solution.

By hand, change the sim2 to 2G/GPRS.

After that put sim1 in 4G.

If you try to change sim1 while sim2 is still in 3G/4G, it will not work.

So first put sim2 in 2G/GPRS mode.

No flashing needed.

Fix for Unmerged Contacts

If ROM is clean flashed :

- go to settings > apps > options > select show system apps

- select contacts > clear data and clear cache

- select contact storage > clear data and clear cache

- go back to settings > accounts > google and sync contacts again

- now install whatsapp and carry on usually .. contacts should be merged fine

If ROM is dirty flashed or if whatsapp is already installed :

- uninstall whatsapp

- now follow from step 1 from If ROM is clean flashed

2. The flashlight in the notification tiles plays hide and seek. Sometimes, it will be there, sometimes it will disappear especially when you need it.

3. Decent battery life, once fully charged, I can use my device for whole day.(not really, like 6-7hrs). Heavy internet surfing with 3G

4. Double tap to wake works like charm.

5. Facebook Messenger crashes/FC

6. Install Facebook app latest version and delete the libsxxx.so file, otherwise, it will crash/FC

7. No problem switching network from 2G to 3G or to 4G and vice versa, as this was seen in the previous build.

8. This ROM is a beast, smooth, fast and efficient. I've Tried all other custom Roms, nothing beats this ROM.

On the small bug side I'll add two more: you cannot disable one of the two sim cards and there is no screenshot tile nor a screenshot button in the poweroff/reboot menu.

For facebook and fb messenger I run as root (su)

find /data/data/com.facebook.* -name libsslx.so | xargs rm

after every update of the two.

[Xiaomi Mi 4i] vronra:
From the previous thread, it is said by devs that disabling sim features was discontinued by CyanogenMod. So in this ROM latest build, there is no disable option available. If you have disable sim features, but unable to disable, I suspect you're on previous build of this ROM. I too encountered the same problem while I was on the previous build of this ROM.

I have screenshot tile, in the notification tile. You can use gravityBox for that.

Or go to button options under Settings-> power button and check the screenshot option.

[Xiaomi Mi 4i] thewisenerd:
hello,

does this ROM have working encryption support?

in cm-12.1, encryption fails with the following error:

I/Cryptfs ( 257): Check if PFE is activated on Boot
E/Cryptfs ( 257): Bad magic for real block device /dev/block/bootdevice/by-name/userdata
E/Cryptfs ( 257): Error getting crypt footer and key

i'm guessing it's because in twrp's recovery.fstab and in the rom's fstab, the "encryptable=" flag is set differently (bk1 partition and footer respectively), and i may entirely be wrong too.

anyways, has anyone tried encrypting their device?

If you want the second sim to use LTE, you have to fist use 2G on sim 1.

So:

1) Put sim 1 in 2G, disabling data is NOT enough. Put it in 2G.

Now it should work.

As far as i know ,encryption problem it come from the firmware

5+ people report that xiaomi mi 4i had encryption problem

Maybe we need to wait their update their source

Also... I think it come from the firmware patching system.... It's patching the partition block right ?
[Xiaomi Mi 4i] thewisenerd:
about the encryption problem: the twrp.fstab in twrp v2.8.7.0 points to the /bk1 partition (by-name) whereas ROM points to /userdata footer 16kB.

So, i tried chnging ROM's fstab to bk1, but that didn't work.

then, i changed both ROM and recovery fstabs back to encryptable=footer,length=-16384.

the problem with this was this:

D/QCOMKeyMaster( 259): keymaster app is loaded
D/Cryptfs ( 259): unmounting /data succeeded
D/QCOMKeyMaster( 259): keymaster app got loaded at attempt number 0

E/Cryptfs ( 259): Error enabling encryption after framework is shutdown, no data changed, restarting system

i'll attach entire logs here.

about firmware patching and system image, i'm not sure what you are talking about. afaik, the system partition is not encrypted. the userdata partition is the one that is usually encrypted.

i can guess why miui does not want encryption, their updates majorly depend upon the modification capability of the userdata partition since they have quite a few of their OS stuff on userdata partition. so, should they add encryption, they'll risk the system bootup process itself. also, they'd have to add support to their current recovery to decrypt /userdata before flashing updates. all too much work for them.

if it were a firmware issue, which i highly doubt; i'm still looking at the kernel. perhaps there is some config that wasn't enabled, etc. that is required for hardware crypt keys.

also, about builds: if it is just about "new builds" as in updated sources, anyone with a server can set up nightly builds even.
