Miui for A820
Android 4.2.1
developed by Reagan
Many bugs fixed.It's stable and has a nice UI.
Miui for A820 is developing.
If you like Miui you can have a try.
If you are interested in Miui you can read other contents.

Some tips of how to use it well.

In settings there is a option of many functions added by Reagan such as CRT effect and my “Dandelion” on the status bar was done by it.
The reason why I don't put much about it is that it disappeared suddenly.It's peculiar and I wonder if I have deleted something important.
In the options there is a functions of changing camera.But the two cameras both cause the change of the color(the method to solve it is behind).That means two cameras are using your storage.Miui's stotage is seldom enough.You can delete one.

The first time to boot is the slowest.The mi logo keeps for minutes.

Enable root in permissions,it's a software(system app)

In settings there is a option of changing defult write disk but didn't work when I tried.
I manage it by edit the text in /system/etc/vold.fstab
by Root Explorer.(you should have enabled root in permissions)

dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/s:dcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host


dev_mount sdcard2 /storage/sdcard1 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard /storage/sdcard0 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host

Why it's so troublesome I'll tell you later.First if you write the wrong code down or you changes the permissions of the file it will be more troublesome unless you like the defult write disk–external SDcard .

There are some apps of ads in it.Please delete them by yourself.

Konwn problems

All miui roms for A820 are ported from other phones. Official catagories like Mi 2S,2A all have large storage and no external SD cards.
This means miui's official developers have not taken these in consideration and in a phone with SD card many problems do exist.
Many miui roms don't have settings like changing defult write disk and we used to manage it by revising some words in vold.fstab.Some roms do have these but not all of them really works.Somehing worse I should mention of it is that in some miui roms after you have changed defult write disk ,your file manager admit it while your games' data doesn't admit it,people said the defult disk is not really changed.Some developers had tried to sovle the problem.
Moving apps to SD card is not supported in settings.And if you do that (such as using some softwares),miui's disability in this filed start to appear(Or you can use SD card only for storage like official miui phones do,then anything works).
If you have apps in SD card and reboot,their icons in miui home will be in the last and their former positions be filled with blanks,your rank of icons be in a mess.Miui home's deveopers has never take it into consideration.You can use other homes.
Things blow can happen when you have moved apps to SD card.
Once I had 75 mb left of system storage,the next morning it had only 11mb left.I don't know what had happened when I was sleeping.Afer that my phone had been warning lacking of storage and couldn't install new apps.Of coure I had see to it that I had moved enough apps to SDcard.If you install enough apps and some of them in SDcard you can be faced with that.
In general I need a lot of apps and some of them have to be moved to SDcard (by Titanium Backup).I moved one by one to SDcard but in some cases the storage didn't reduce much.The system had not calculated rightly because afer rebooting the storage successfully reduced.

If you use Wifi Master's (seems to be old version such as 0.8.2 beta)advanced connecting it will stop during the process.A window comes out to ask you for password.This bug can only be seen in many miui roms.

The camera seems not good in dark environment ,comparing with official roms.

After using camera the color changes.You have to recover that by rebooting.
Use this camera and you will solve the problem.
From android 4.4


You can stay at the first lenovo logo or the Mi logo.Plug out your battery to cut off the power.Then try again.
Sometimes between the two logos came out a picture of two bad“lenovo”,I thought it was somehow scary but I successfully entered system.

Miui have a option of auto connect in wifi settings,it's enbled first by defult.If it's enabled you may not successfully disable or delete(especially for open networks)by custom apps such as wifi connection.It connects automaticly,which had troubled me at first.You can disable it in wifi settings or delete ,switch connection in miui's wlan settings.

More to be found by youself.

    The first and the second are from different developers.
    I just described Reagan’s rom because I only tried it.
    The other one is from official website of miui so I think I neen’d have a try and it’s good.
    Reagan’miui supports English and Chinese.

    Reagan’s rom has been updated.
    Icons won’t be mixed up anymore.
    Though the post is originally for a developer,the bug is rather annoying.I’ll upload it again,I think.

    Thanks for the effort put into collating these links WhiteSnow. I get tired of researching Chinese brushes :)

    I had the ever diminishing internal storage for apps on 4.1 ROM from either infrared or manowaracero. Every time I installed an app it would pop  up a warning saying I had between 0.5 and 2Mb remaining (randomly?) but never prevented an install. I bet it was manowaracero v1.0
