04/25 has 23 possible network combinations. Only GSM is the #22; GSM/WCDMA is #23; and there are more...

---------- Post added at 10:59 AM ---------- Previous post was at 10:25 AM ----------

Well, if

1- with MIUI you did not have that problem;

2- you did all the wipes (I think I also did System wipe the first time, not sure anymore) + (with TWRP 3.0.3-1 recomended for Mi4C: I had problems while using different TWRPs, after installing the new Bootloader/Blobs for android 7)

3- I don't have that problem so it's not a ROM (04/25) bug

- It may be a hardware problem: you should check the headphones (you never know if in the meanwhile a cable has broken off...?) - try to connect computer desktop speakers to the phone, or another pair of headphones, try your headphones with another phone. It may be a jack entrance malfunction on the phone

- you should check for any thrid party app you are using to listen music (I only use third party apps if I don't have a choice)

- you should dig into the system configurations to check if any of them have implications with "audio out" (I don't believe that, but...)

Sorry if I can't do more... hope you'll find the solution

All systems have bugs. Microsoft have been doing Windows for 36 years now and it still has a lot of bugs...! Linux releases and Macs have bugs...

The point here is trying to figure out which problems are due to bugs and which are due faulty installations... that's why devs ask for people to be carefull while reporting false bugs.

Usually when a lot of people have the same problem it is a bug, but when only one person has some kind of a problem usually it's due to a faulty installation.

As far as I could understand here, like 90% of the problems are due to faulty installations (roms or gapps). I always follow dev's recomendations regarding wipes, gapps releases, twrp version, etc, and I almost never have problems.

I had heating problems with MIUI - that's the reason I left MIUI (I was starting to mess around with governors and other CPU stuff, going crazy)

I had random system crashes with RR 04/18 also reported by other users... and that's all.

Now I think I am going to keep 04/25 for a longer time.

Hello,

Sorry for my insistence but I do not have access to recovery.

If I do "reset factory data" return to miui 8.0.5. With "My recovery",

I think that's what the phone had when I buy it,

And from there install TWRP 3.0.3-1 of Andrpax and then RR 25.4

Thank you

[Xiaomi Mi 4C] adittg:
recently i've updated my mi 4c firmware, and as you said it will locked my bootloader

yeah it does... and i have a problem to unlocked it again...

im confused, is it possible to unlock from this custom rom? or i had to go back to MIUI ROM to unlocked it?

i already have the permission, but when i plug my mi 4c via usb (fastboot mode) in mi unlock software, it doesnt read my phone...

here's the screenshot

please help me, thanks :)

---edit

If I only want root access, is it possible with this locked bootloader? How??
[Xiaomi Mi 4C] Pawliko:
You have to flash MIUI CHINA DEV, then unlock bootloader.
[Xiaomi Mi 4C] Shervrar:
Not sure what you mean with 'full', since as far as I understand android only ever encrypted /data, not the actual system files.

That said, encryption does work.

ROM updates can be applies using TWRP as usual since it should not be touching /data.

If you need to flash a update.zip to the /data partition use flashfire.

Note / Personal experiance:

On the latest build (20170502) setting the password sometimes mysteriously messes up. Setting "12ab" did work, but setting my password (12-characters, mixture of numbers and letters (both upper and lowercase)) did not work and kept telling me the password was wrong, I should try again after 30 seconds. So, before you enable encryption make sure you can even unlock the screen, as you will not be able to reset the lockscreen from recovery after encrypting the phone (and possibly not even start your device).

Also, I advise you to encrypt it ASAP. Persoanlly, I never had any luck encrypting anything where I already had all my apps and data set up..

EDIT:

Found out why the lockscreen failed I think. Do not turn on "Quick Unlock".
[Xiaomi Mi 4C] a4c01:
What's new in latest version?

It would be nice if you could post changelog here or somewhere... ;)
[Xiaomi Mi 4C] takotestas:
I can confirm that this is possible. My phone was unlocked with RR installed. But I had various versions of MIUI dev installed before unlocking. I think that this helped me to resolve 50 % problem (Current account is different from the account info on the device) during unlocking.

Your problems can be related to drivers or cable. Are you able to see device ID by using Miflash tool?
[Xiaomi Mi 4C] cezarmed2:
The permission for unlocking is Mi account related not phone related . But if you had the account linked to the phone WHEN applying for permission it might unlock.

[Xiaomi Mi 4C] adittg:
SOLVED!!! The official unlocking method is can be used with this custom ROM,

So I can confirm, you don't need to go back to MIUI to unlocking bootloader

If you already have the permission from Xiaomi, then you can directly unlocking bootloader with official xiaomi software from this custom ROM

And actually my problem is simple, I am forgot to check the developer tools in my mi 4c, where you have to enable the USB debugging mode and enable the OEM Unlocking

Thanks for all of your answer, sorry I can't multi quote you all :) :)
[Xiaomi Mi 4C] sultanbrunei:
Im in the latest RR rom. my bootloader is locked I think.

What should I do to re-unlock my bootloader so that I can install, access recovery and stuffs?
[Xiaomi Mi 4C] takotestas:
You need to know this for sure. Printscreen shows that bootloader is not locked. You can double check this by using fastboot oem device-info command when phone is in fastboot mode.

Results like this means that bootloader is unlocked:

(bootloader) Device tampered: false

(bootloader) Device unlocked: true

(bootloader) Device critical unlocked: true

(bootloader) Charger screen enabled: true

(bootloader) Display panel:

Can be that you are right, but i don't believe in this. I have collected bad experience - unlock process of my phone took almost one and half month. I got unlock permissions in short therm but faced with 50% error like thousands of people around the world. I have tried all possible workarounds but nothing helped me. Root cause of this problem can be related to experiments of Chinese sellers - my phone came with old xiaomi.eu inside. Can be that another MIUI account was used on this phone before I got it. Also can be that I got refurbished item. But again I got clear understanding that Xiaomi is having problems with data synchronization between datacenters. And they are not able to solve conflicts inside databases in short therm.

It worth to try fully configured latest dev rom when you are getting 50% error (Current account is different). Because this can force synchronization of data betweeen Xiaomi databases.

From another perspective I have learned how to survive with locked bootloader. So we not need this in general :)

The ROM is great and I'm glad I use it.

However, I seem to have lost root access. After first boot, Magisk Manager tells me the phone is unrooted; after reeboot it shows that root os OK. However no app can obtain root (Titanium, Tasker, ...).

Flashing SuperSU leads to a bootloop (which can be resolved by flashing RR again).

Right now, I'm using RR RR 5.8.3 (20170502).

Any hints?

[Xiaomi Mi 4C] Knoore:
I think I have an issue.

While being on RR 5.8.1, I tried above steps, so I installed the flashable zip with firmware, and I requested Xiaomi to unlock my phone (which was granted).

However, after flashing the zip my phone does not boot past the MI logo, and when going into FASTBOOT, and run the MI Unlock tool, it says my device is not supported by Mi Unlock.

Trying to flash MIUI rom images via fastboot fail since it says "Remove device is locked, can not erase".

Any suggestions on what I could try?
[Xiaomi Mi 4C] cezarmed2:
The unlocking permission is Mi account related, not phone related. If Xiaomi can't link at any point that account to your phone then you can't unlock it. I've said this a few posts back.

I can't think of anything but a downgrade using MiFlash.

Hi,

I decided to install this ROM. As a first step, I flashed the firmware, mentioned here. The log showed me that the update was successfull, but since than may phone is not booting either in normal mode or bootloader mode. Fastboot works. Could you please give me a hint? I am kind of cut from the world now...
[Xiaomi Mi 4C] RFMC:
I would try to flash TWRP (3.0.3-1) through fastboot with "minimal_adb_fastboot"; once the TWRP is running, and if the firmware is also installed, I guess I would be good to go with the ROM.

---> https://www.xda-developers.com/how-to-install-twrp/

Hope someone with more experience here may give you more or better information.
[Xiaomi Mi 4C] miklos13:
Thanks for the idea. I am on Windows, and minimal_adb_fastboot is for OSX and Linux, as I see. I have installed the adb as it was describet in the twrp link you gave me.

I turned my phone into Fastboot mode, I connected it to my computer, in device manager I can see an "Android Bootloader Interface". But when I run "adb devices" it cannot find my phone. MiFlash sees it however.
[Xiaomi Mi 4C] RFMC:
I am on Windows too, and I have ADB+Drivers installed. Did you get to this part of the tutorial: "Install via ADB"...? You really have to go through a command window (open it as administrator inside the folder with TWRP *.img file).

PS: I remember that sometimes ADB did not flash the TWRP the first time, don't know why... but after a reboot of the phone, or something like that, it eventually worked.
[Xiaomi Mi 4C] miklos13:
Using a command window is not a problem for me, but adb cannot see my phone, as I wrote. If I type "adb devices" the result is an empty list. If I start to run the commands in the "Install via ADB" section, I get an "error: device '(null)' not found" message.
[Xiaomi Mi 4C] RFMC:
Looks like a driver problem, even if MiFlash sees the phone - it should be a ADB/driver issue. There's plenty of posts in the Internet regarding ADB/drivers issues.

I've used "adb-setup-1.4.3" before the latest major Windows 10 update (which by the way is messing with hardware drivers)...

I will keep looking for some tips...

PS: I did install the latest MiPhoneManager - I guess the drivers I have came from there...

EDIT: found this tip: "Seems like your phone is in bootloader/fastboot mode instead of in-rom ADB or TWRP ADB mode. This is the mode you're phone has to be in to be able to flash other recoveries like TWRP which however also requires your phone to be OEM bootloader unlocked (which completely wipes your phone), and from there you enter TWRP recovery using bootloader menu or power plus volume down, and there flash the latest 2.79 SR3 SuperSU to archive root/sudo functionality. Either that or you actually did activate ADB under development options and accidentally installed the ADB device using the fastboot/bootloader driver instead of the ADB device driver." ---> https://xdaforums.com/oneplus-3t/help/device-shown-list-devices-trying-to-root-t3598866
[Xiaomi Mi 4C] miklos13:
Hi in the meantime I found that since my phone is in Fastboot mode, I can only use the fastboot commands, but not the adb. So I tried to run 'fastboot flash recovery' the twrp image, and I get this error message:

"FAILED (remote: Partition flashing is not allowed)"

After some googling, it seems that the firmware update not just bricked my phone, but also locked my bootloader (as it was written as a possibility). I run

D:\>fastboot oem device-info

...

(bootloader) Device tampered: true

(bootloader) Device unlocked: false

(bootloader) Device critical unlocked: false

(bootloader) Charger screen enabled: false

(bootloader) Display panel:

OKAY [ 0.057s]

what proves this too.

So I need your help now to figure out, how to get my Fastboot only, bootloader locked phone work again, ideally with Resurrextion OS, more ideally without loosing my date (photos, backup files, etc) on my phone... I have my previous firmwarem so if I could load that back, that might help too, but I don't know how to do that via Fastboot.
[Xiaomi Mi 4C] cezarmed2:
You can 2 things. You can unlock your bootloader with MiUnlock or you can downgrade by flashing 6.1.7 via MiFlash. I'll link here one or two ways of downgrading.

https://xiaomi.eu/community/index.php?threads/39608/

See if this works. There is a guide on that topic.

[Xiaomi Mi 4C] RFMC:
Well, my bad:

1- I did not use ADB commands only Fastboot commands, so I didn't even thought about that...!

2- because you said you got your firmware here, I thought you would have your bootloader unlocked by now (and that was the strange thing about your issues), because Andropax wrote that your bootloader would became locked...!

"If you have previously old bootloader example from xiaomi.eu 5.1 rom or unlocked bootloader by unofficial method (without xiaomi permission) this will lock it ! (...) you need to unlock it by official method and mi flash unlock."

What I did was unlock it just like he said: with the official Mi Flash Unlock. At this point it might be the best choice - but perhaps someone here could suggest an unofficial way of doing that...?
[Xiaomi Mi 4C] cezarmed2:
I just did. That's taken from the old unofficial way of unlocking the bootloader.

I strongly recommend unlocking officially if possible.

Unlocking with the unofficial method means it. Will get locked again by flashing a Nougat ROM.

[Xiaomi Mi 4C] miklos13:
Thank you for both of you!

I bought my phone from a local webshop and it came unlocked, I guess now they did not use the official way....

I already started an official unlock on http://en.miui.com/unlock/ but by now I haven't received the sms with the code.

How long does it usually take to get it?
[Xiaomi Mi 4C] cezarmed2:
7 days. It doesn't always send an SMS so to be sure try unlocking it daily.

Mi4c comes pretty much unlocked from factory, with few exceptions.

Permission for unlocking is transmissible. If you have someone that already has unlocking permissions, burrow his MI account.

Trimis de pe al meu Mi-4c folosind Tapatalk
[Xiaomi Mi 4C] RFMC:
cezarmed2 is right: the point is that doing it unofficially usually means downgrade the phone to an OEM stage, and then upgrade it again, and once you get to the Firmware 7 or a MIUI Nougat ROM you'll get the bootloader locked again. At this stage you already have the MIUI blobs (firmware 7), so the Mi Flash Unlock will recognize the bootloader (because it's a MIUI blob) and will unlock it... then you're good to go (TWRP + ROM).

- For me it took like 10 days, for some people more, for others less... good luck with that.
