Somebody tried new build?

IMO MIUI is good enough for daily using and gaming - I like prefer MIUI UI more than stock Android (Material Design is amazing, but MIUI is still better :P).

How to install superSU? I got stuck on RR boot logo when flashing SU2.79. Im not a fan of magisk, some tools doesn't seem to respons magisk root.

5.8.2 is more bugy than 5.8.0 i think. Im rolling back to 5.8.0 latest build until the rom smooth and stable again. And offcourse with the way to install superSU
[Xiaomi Mi 4C] likhon02:
any one using the new build?? any thought ??
[Xiaomi Mi 4C] miklo01:
Ok. MD5 was changed, I downloaded ZIP and installed. Phone works ;)
[Xiaomi Mi 4C] hansip87:
i have tried 0316 build, and it's definitely a lot smoother than 0312. The only thing that is missing is the Camera API2 is not activated even though build.prop is edited and applied and rebooted. Still testing for battery life though. so far recommended for you guys to flash.
[Xiaomi Mi 4C] likhon02:
install the rom update magisk manager app from play store then uninstall magisk using magisk manager then go to twrp and flash supersu
[Xiaomi Mi 4C] FadjarDarwin:
Thank you! I'll try it on the latest build tonight. Thank you once again
[Xiaomi Mi 4C] dominatos1:
is there a chance that fingerprint sensor will ever be working on mi4s? i love this thing and do not use CM based firmwares only because of this reason.
[Xiaomi Mi 4C] neosickle:
Guys, I just want to ask if a ROM that uses android 7.0 uses a different firmware version to a ROM that uses 7.1.1?
[Xiaomi Mi 4C] likhon02:
new build is definitely smoother but big cluster is always offline or its just me??
[Xiaomi Mi 4C] wertus33333:
Did you try mi-globe rom (u can choose which bloatware u want) with govtuner? In earlier build setting govtuner to performance mode brought back my 2 big clusters and gave an amazing performance for gaming (while s7 edge completely stock was lagging as hell).

I cant tell now because i no longer play on mobile but pc ;).
[Xiaomi Mi 4C] Infernojz:
Hello all, Are you interested in porting sailfish os for mi4c?
[Xiaomi Mi 4C] neosickle:
No, i never know. But let me try. Last time i am on xiaomi.eu before going here. Thnx for the info.

---------- Post added at 04:31 PM ---------- Previous post was at 04:05 PM ----------

I have a question guys. Does a rom that uses 7.1.1 uses a different firmware version with a rom that uses 7.0?
[Xiaomi Mi 4C] wertus33333:
You mean miui (there is a 7.1.1 version?) ? Should be the same. And there is no custom rom which comes with its own firmware.... You need to flash the fw zip from first post (or the miui update) to update to Nougat bl and fw (required for RR).

but if RR works you probably already have the newest one ;)

If u wannah downgrade to lp bootloader (which u need for AICP) try to flash a 5.1.1 version of miui 7/8 or go accordingly to this guide: https://xdaforums.com/mi-4c/general/guide-unlocking-mi4c-bl-verification-t3336779

btw, here is govtuner thread (so u know how to set it in terminal):

https://xdaforums.com/android/software-hacking/mod-gov-tuner-project-29th-june-2016-t3407828

U can also try it on any other rom except for the ones with magisk root (so newest rr wont work, u can try lspeed on RR instead).
[Xiaomi Mi 4C] neosickle:
Yes i am trying aicp that's why it came to my mind because when i flashed aicp it failed to boot. I just went to mi logo then power off automatically. For what i have read aicp is now on nougat, they have 12.1 for libra which is nougat. I read it when i flashed it. It says version nougat 7.0

Btw i want to try the govtuner but i think it wont work. I am using the newest rr. Have link for lspeed?
[Xiaomi Mi 4C] fuyoo:
Latest rom is a lot faster. Thanks.
[Xiaomi Mi 4C] kvbb:
0316 is smooth and fast, nice :)
[Xiaomi Mi 4C] takotestas:
I'm using latest build at least for 12 hours. No problems found until now.
[Xiaomi Mi 4C] Antyhaker:
What about stability in gaming?
[Xiaomi Mi 4C] likhon02:
is two big cores are working properly for everyone?? big cluster is always offline here :/

---------- Post added at 11:30 AM ---------- Previous post was at 11:28 AM ----------

can you check your kernel manager if two big cores are online under pressure? for me its always offline
[Xiaomi Mi 4C] SOK4:
Comrades!

I cant's install this FW on my MI4S anymore.. Last installable version was 2017-02-25..

Why there is no support for MI4S in last builds? :(
[Xiaomi Mi 4C] david320te:
Finally Updated to 5.8.2...apparently i had the newest blobs already on the device.

Runs beautiful! I'm actually pretty impressed how smooth it is and that i still have 23% left after playing around with it for a while. Substratum is also working great now. Whatever happened to the Camera between the last 5.8.1 Build and the newest one from the 16....i actually can make sharp pictures in low light conditions now. Never been able to do that. Now even when zero shutter lag is turned off, the pictures are pretty decent. Noise has also been reduced somewhat and contras ratio looks better. White Balance is still off sometimes, but hey, that's something that's easily fixable with Snapseed or else. RAW Photos also seem to be better (or rather with more information)
[Xiaomi Mi 4C] takotestas:
I'm not playing games. But 5 cores are always enabled on my phone. I have tried to create screenshots during Antutu test run. I have seen 6 cores working but for short time only.
[Xiaomi Mi 4C] takotestas:
I have successfully enabled camera2API on 0316 build. But again this feature is not usable because of screen flipping and lag.
[Xiaomi Mi 4C] likhon02:
I can't get big two cores to work. Getting this error on kernel auditor. can any one tell me how can I fix this ??
[Xiaomi Mi 4C] IcyGlacial:
it is normal, you cant just turn it on by switch , when you doing heavy task it'll automatically turned on. but the problem is big core tend to offline most of the time (On rr and aicp)
[Xiaomi Mi 4C] likhon02:
no it's not normal.i did not had any issues on previous build even on heavy pressure 2 cores stays offline. I think it's a bug
[Xiaomi Mi 4C] Chenyun_Kang:
TWRP new version 3.1.0 can use adb make a Nandroid backup directly to PC (my data is too big for internal storage), anyone tried this? I tried and failed.
[Xiaomi Mi 4C] miklo01:
Backup via USB doesn't work. Try to otg backup.
[Xiaomi Mi 4C] likhon02:
bbcode image link

device under significant pressure still two cores are offline. on previous build performance was a bit laggy but there wasn't this kind of issue.how can i fix this :confused::( any help will be appreciated. Image takes a while to load please wait for it
[Xiaomi Mi 4C] takotestas:
It seems that I have reproduced your problem. It is enough to use torrent client for few minutes and CPU is getting hot. Big cores turning off when temperature breeches 38.7 Celsius threshold.
[Xiaomi Mi 4C] galcat:
Why can not I install the rom ?

I get error messages such as -

error flashing zip

or

Error Executing updater binary in zip

or

no md5 file found

And why I want to install package extended of gapps - I get error messages such as 70.
[Xiaomi Mi 4C] fuyoo:
I have also observed the same issue with the big cores going offline when temperature just rise by a bit. For me, I noticed core 4 is always offline whilst core 5 (the numbering starts from 0) is still available most of the time until it gets slightly hot.

My solution to this was to alter thermal settings in Kernel Aduitor to SoC temperature limit. But somehow this setting wouldn't automatically apply on boot so it wasn't sustainable.

I've switched back to 0220 build and this issue does not exist. I suggest you do the same and save yourself the pain of a really slow device after some use.
[Xiaomi Mi 4C] Hellgates:
Please add the shutdown alarm function.This is a very useful feature.And thank you for your great work！@AndropaX
[Xiaomi Mi 4C] FadjarDarwin:
I got an issue with wifi and mobile hotspot. Tried to change wlan_mac.bin from my previous rom to fix this issue(succed in any previous build 5.8.0). But now everytime i try to edit the file or replace with a new one, it'll bring back the wrong wlan_mac.bin from the rom installer. As the result, wifi and mobile hotspot won't work.

Any idea how to edit/replace the file?
[Xiaomi Mi 4C] Uzuki:
Can't you just delete the file wlan_mac.bin? As I recall this file is generated by system. Did u just tried to change the Mac address?
[Xiaomi Mi 4C] FadjarDarwin:
Yes i tried both way, but the file keep rolling back to system original. I tried it with magisk and superSU, and still nothing changed.
[Xiaomi Mi 4C] munji:
Hi, I have try this ROM 0316 with clean install but screen blank on first boot after mi logo and my mi4c Off.

the latest ROM working on my mi4c is 0214 :(

anyone can help?
[Xiaomi Mi 4C] saveonresearch:
I had similar issue. Do you use TWRP? I had to reload TWRP via fastboot. Then reflash the 0316 build.
[Xiaomi Mi 4C] kayyara:
Hello! Tell me how to update correctly from the version of RR-N-v5.8.2-20170225-libra-Official to the latest RR-N-v5.8.2-20170316-libra-Official? The loader is unlocked, twrp 3.0.3.1.

When I update, the new version, many errors come out, oppen gaps set the same
[Xiaomi Mi 4C] munji:
Yes I use TWRP 3.0.2-0 and flashed via fastboot, what I've been done:

- reinstall stock ROM

- flash TWRP

- install RR 0316 + latest gapps

Result: failed, same issue :(
[Xiaomi Mi 4C] FadjarDarwin:
Read carefuly from the first page, it has some requirement on installing 5.8.2 rom. Twrp 3.0.2-0 won't work.
[Xiaomi Mi 4C] munji:
where is download link new firmware

5. Boot into recovery, insert 3 file to your storage: new firmware (from front page), the new rom, AND the gapps.

I can't found new firmware from front page, where I can download it?

Thanks
[Xiaomi Mi 4C] Uzuki:
Did you really read the front page, it's at section requirement: N firmware, there's a link, download from there
[Xiaomi Mi 4C] munji:

I had just unlocked my bootloader officially through miunlock app.

And I still can't get into recovery mode.

flashing twrp through flashboot doesn't work. (eventhough message is successful)

flashing twrp through twrp manager gives error message.

WHAT HAS GONE WRONG ??

is it because I flashed twrp 3.1.1.0 ??

---------- Post added at 09:59 AM ---------- Previous post was at 09:54 AM ----------

I tried to flash TWRP 3.0.2.0 through TWRP manager. message is successful.

After rebooting, same ****. Stay locked in mi.com logo.

What's wrong? please help.

This is the weirdest ever since my first android.

---------- Post added at 10:05 AM ---------- Previous post was at 09:59 AM ----------

Even after successful twrp flash via twrp manager,

every time I got back into twrp manager, the message says:

custom recovery not installed or not detected.
[Xiaomi Mi 4C] jimzhong:
I found that turning on WiFi in airplane mode will disable airplane mode since the 3/09 version. Is it a new feature or a bug?
[Xiaomi Mi 4C] sultanbrunei:
I've successfully upgraded my ROM to the newest ROM, again, using this method.

This time, before I tried anything, I've done official unlock through official MiUnlock app. It already said successfully unlocked. However I am still unable to flash twrp and then boot into it. Always got stuck in mi logo.

Now, after successfully installed new ROM, I am trying to install new twrp (using xiaomi twrp flashed and successful), when I tried to enter recovery, again I got stuck in mi logo. I guess this is because bootloader is locked again, eh ....?

I already attached the fastboot command prompt that I checked after installing the rom. Please help check what is the meaning of the status?

DEVICE UNLOCKED: TRUE

DEVICE TAMPERED: FALSE

Also, when I try to once again unlock the bootloader through official miunlock app,

it says, couldn't verify device.

Are there any steps that I have done wrong?

Please help.

I NEED TO INSERT TWRP INTO THIS DEVICE SO THAT NEXT TIME I WANT TO UPGRADE THE ROM, I DO NOT NEED TO REVERT BACK TO OLD BOOTLOADER ETC.
[Xiaomi Mi 4C] adewisman:
Seems you are still on old bootlader (lollipop) as theres no emergency/critical mode option available on your oem device-info, its better to flash miui dev nougat rom then unlock your bootloader again with miunlock tools, and then flash the new twrp by andropax on fastboot, then flash rr and gapps on the new twrp. Hope you got it sorted.
[Xiaomi Mi 4C] sultanbrunei:
1. Where can I download the miui dev nougat rom?

2. How to precisely know whether my bootloader is truly unlocked or locked?
[Xiaomi Mi 4C] adewisman:
1. http://en.miui.com/a-234.html > choose mi4c install it on fastboot mode using miflash

2. Well you already on unlocked bootloader base on your fastboot oem device-info ss but RR need you to be on latest bootloader (nougat) and firmware too, to be able to boot your phone on latest RR rom, just type fastboot oem device-info when you already on nougat bootloader you will find the difference.
[Xiaomi Mi 4C] sultanbrunei:
I think I have already flash the new N (nougat) firmware, before I installed this new 0316 rom.

I got the link for N firmware from the 1st page.

That should be the correct firmware that you wanted me to flash right?

Now, I have no problem to boot my phone into latest RR rom (0316). The only problem is I can't boot into TWRP recovery, because there is none installed.

And everytime I tried to flash TWRP, whether the process says 'success' or 'failed', it still seems to me the twrp recovery were never 'flashed' or 'installed'.

I can confirm this by installing TWRP manager, and everytime I saw the status of recovery from there, it always says no custom recovery installed.

Now the question is why? Is it because my bootloader is re-locked after installing this new ROM?

From the screenshot I attached above, does it says that my bootloader is currently unlocked or locked?

If it is TRULY UNLOCKED, why is it that I have problems flashing TWRP into this device?
[Xiaomi Mi 4C] adewisman:
Yes you already on unlock bootloader

Try this one:
[Xiaomi Mi 4C] vanvonvin:
i've use this one. i hope it successful.
[Xiaomi Mi 4C] bayoedevour:
Is this possible to downgrade with flashable zip?

Anyone else getting SafetyNet Error - CTS Profile Match: False in Magisk Manager?

I flashed (MiFlash) latest China Dev MIUI to unlock bootloader with MiUnlock, then flashed TWRP 3.0.3-1 using fastboot and installed RR 5.8.2 along with latest OpenGApps Pico. I did this yesterday so it's a clean installation.

What should I do to pass the SafetyNet check?

man i feel like any 5.8.2 build are having some issues.. The battery life is 1 hour shorter than before, the A57 cores is offline all the time.. Does anybody remember which build is the best so far? I prefer to flash back but i just forgot which one was the best @_@
[Xiaomi Mi 4C] likhon02:
for me 0225 is working great btw new build is up :)
[Xiaomi Mi 4C] likhon02:
i think devs should turn off core control by default as it turns off two cores.
[Xiaomi Mi 4C] Nard Cox:
Is the 0309 the latest stable build as indicated in the OP? I'm still running 0214 and would like to upgrade. Will have to read upon the whole updating to 5.8.2.

[Xiaomi Mi 4C] yellowbrick:
Everything runs smoohtly on my Mi4c even after some days! I don't experience my phone getting slower?

My biggest issue is, that Core 5 and 6 are always on lowest frequency, even though my phone is under heavy load.

btw. does already exist an OC kernel like on the Marshmallow Edition? Or how did you guys overclock your CPU?
[Xiaomi Mi 4C] forsingod:
Hi. After installing this firmware, wifi works very slow. What the reason can be?

This is happening for a very long time now. Not sure what the problem is, but i had this since Android Lollipop with the Mi4c.

[Xiaomi Mi 4C] Nixen241:
You can try to flash propertiary blobs from miui v8.0.7 or sth like that, it was in marshmallow thread, if it didn't work, you'll need to try v7 blobs etc...

It might work, so it's worth trying ;)
[Xiaomi Mi 4C] artebo:
Hi, guys! When can we expect new build?
[Xiaomi Mi 4C] philipnzw:
Don't think it's nice to ask when we are getting new updates , this gives the dev a lot of stress

Anyway if there's little change in rr then frequent builds are even harder to make worthwhile

Besides , his hard drive is running out of space lol

Not trying to be rude here but i think we should be more patient ;)
[Xiaomi Mi 4C] artebo:
Ok.
[Xiaomi Mi 4C] david320te:
I haven't noticed those wakelocks. I was talking about the Wifi Disconnecting in standby, while it still was turned off in the settings...
[Xiaomi Mi 4C] Vinndimon:
My 4s wi-fi performance is very bad on this rom too. It also was on CM13. Maybe it relies on router but it's definitely not a router problem because wi-fi was ok on MIUI. You can check out thr next topic with CM13, there were some thoughts on that case.
[Xiaomi Mi 4C] jlnamyh:

Hi,

You from France with a mi 4s.

Thanks for your hard work. It works fine here.

Do you have Google restore after a factory reset? I tried 2 or 3 times but Every time I have to full reinstall apps data..... It is quite annoying.

Am I alone in this case?

Bye.

Edit: I've solved my problem by flashing stock Gapps. Everything work fine except Google camera. Installed another one from store.
[Xiaomi Mi 4C] likhon02:
Same here..in miui it has no problem and i cant stand miui..
[Xiaomi Mi 4C] FadjarDarwin:
For me, the best build is the last 5.8.0
[Xiaomi Mi 4C] hansip87:
Yeah i agree too. But the last build is quite solid and the A57 core works again. Haven't tried it in game though, but the battery life is (subjectively) feels better now. Will report back in 2 days..

Lel, in firdge is something around 5 celsius degree, so there's no way to kill your phone.

In winter is colder and i never heard about dead mi4c phone becouse of winter walk. :P
[Xiaomi Mi 4C] made-in-tirol:
I have the same problem! any help?

if you go to downgrade to a early build before nougat blobs includeed I would recommend you to flash first a MIUI stable build (Android 5.1) to get the old bootloader.... after that flash Twrp and then RR build
[Xiaomi Mi 4C] Cozzmy13:
Put a bottle of water in the fridge. Let it cool. Pull it out. Water in the air will hit the cold bottle and condensate. Now you've got a wet bottle. The same can happen with a cold phone. Technically it can't happen because the phone is powered on and hot, but at idle it can go to room temperature, which is low in the fridge. Better safe than sorry. ;)
