Redmi 4 is a mid-end device released by Xiaomi (along with 4A, 4 Prime) in November 2016. The device itself is very similar to Redmi 3S in every aspect, expect it has a few improvement to some components. (For example the Wi-Fi, where 5GHz connection is now possible)

Unfortunately no
There is a Global ROM available from the official MIUI site, but it has in-calling bugs, and is not released officially.

Clean android....

Hello, i'm new user on this forums. I have very big problem with my device.
I got second model of Redmi 4, first one had malfunction of SIM module (after instaling CM 13), and device wasnt detecting SIM's at all (what more interesting SD cards was detected) on both slots. After service i got brand new Redmi 4, installed CyanogenMod 13 as only properly working OS* and starting to have the same issue.

*So now let me explain why i threat CM 13 as only working OS - it uses battery as it should. On every MIUI (which seems to not be official) including MIUI 9 my battery just drain. For example with 1-2 hours of daily usage on CM my battery can keep 7-14 days, which is perfect resoult, while on MIUI even unused device is keeping max 4 days, and battery usage says Android OS and android (process names) eat 40 % of battery (sometimes up to 56%). I'm installing OS by full wipe, so its not the case of files remaining from older OS.

NOW final question to all specialists here - from where can i get CELAN ANDROID MARSHMALOW or NOUGAT for my model (Redmi 4 prada)? Installation as i understand properly is the same as in case of ROM right (TWRP) or maybe flash?

Please answear, i'm looking over internet 2 months right now, and spending all my free time after job on unsuccessfull searching for help.

Hello,

After I flashed my phone to MIUI 9 (can't remember which one - so many I tried), I got the success message on MiFlashTool, but my phone didn't restart. It was dead.
I mananged to revive it but I had lost many sensors, like wi-fi, bluetooth, etc. I managed to fix those and then I was getting an error about IMEI (can't ID the device) or something like that. Basically my IMEI was gone. I found a fix for that. The phone can now detect the SIM card.
My issue is that it can't connect to the GSM network of my carrier.
I double checked the APN settings - they are good. When I dial *#*#4636#*#* I see the 'turn radio on' button but it doesn't do anything.
Switching back and forth between different versions of MIUI did not help. I tried flashing the NON HLOS bin file via command prompt, I got the okay message, but it didn't fix the problem. I tried flashing the 3 modem files via TWRP, again, it didn't fix my problem.
They talk about restoring EFS on a thread, but I don't know how to do that or if that will help. I don't have the back up files anyways for EFS.
Can anyone help?
Currently I am on CyanogenMod 13 (OS 6.0.1).
Thanks
Andrei

Wow, you really mess up bro...
Let's see... First I advise you to flash the official fastboot ROM from the official forum and see if boot normaly.


If not, you can try unbrick the phone by 'test points'.

Hey
Thanks. The phone boots normally, everything works except for the radio. All commands for the radio can't be changed. If I do *#*#4636 phone information, I see my SIM Card, it shows my carrier (Rogers). WHen I click the 3 little buttons to select the band it shows unknown and lists a few options, including the one I think it the one I need (GSM 850/1900 - i'm in Canada). When I select that band it shows unsuccessful....What can it be?

I must admit that is out of my league.. Sorry

You saying the radio is turned off and can't receive calls? You don't have signal?

In the 'Phone Information', in the button of the page, there is a option that say 'Turn Radio On/OFF', try it.

But... You say you have some modem files, right? If is the same I used when I change to a custom ROM, maybe can help. Try flashing that files in TWRP.

Sorry, I remember now one thing...
Which fastboot ROM you use? China Stable or Dev?
Try use the Dev ROM and in Miflashtool, select 'Clean All' option.

Hope this work

Thanks. I tried all those things many times before. My radio functionality is faulty. I cannot enable the radio.

Then only by test points, don't see any other options.. At least for now..

 

[camilleisfunky]

What is the benefit of using test points vs fastboot?
Thanks

Well... The test points is more for when the phone is really mess up, phone don't boot, not enter the 'fastboot', etc... normally know as 'hard brick'. It's the "ultimate" recovery.
In the PM I send to you, there is a link to a post in the official forum explaining where, and 'how to' do.

But... If you are not comfortable doing that, then, don't do.

Anyway... I can't help you more, sorry

Try asking in the official forum for help. They are more active than here.
