Thanks man, awesome job!

Hey guys. Thanks for the guide, I'm stuck however. I installed the latest global developer ROM in order to root and flash twrp, but there is no native option to root the ROM. What am I doing wrong? Bootloader is unlocked with xiaomi approval. Or is root China Rev ROM exclusive? If yes, the op should make that very clear, so that even dimwits like me understand it.

Hi there,
I did not use global ROM, true, don't know if possible with it.
Did you perform this step?
- Connect to WIFI
- Setting > Permissions > Root access
- Activate root access
The phone will then download a bunch of things and reboot.
After that you will be able to install TWRP and give it root access.

If not, tell me, I will update guide,
and you can reinstall Chinese ROM, to complete process, a matter of a few minutes.

Let me know

Rotpeter · Nov 14, 2016

Thanks for your help! I already fixed in in the meantime, though. The permissions app only shows the root-button, if you are on the Chinese dev ROM. Which I wasn't (global one instead). Maybe you should add some extra weight to that in the guide. Other than that, it worked like a charm! Thanks buddy!

Edit: Sorry, didn't see that you pretty much already wrote all of that.

Hi,
I have problem after this step

Install TWRP:
TWRP will download and install itself (Click Yes to try flash, Yes to reboot to recovery)

Answer from TWRP is Success, but after reboot to recovery there is no TWRP, just MI logo all the time.

Model is Redmi 3S Global

and of course:

C:\xx\platform-tools>adb disable-verity
Verity already disabled on /system

parphane · Dec 22, 2016

Have you downloaded the TWRP version for the 3 S? Not the Redmi 3?
I am not sure what are the differences here, but maybe the phone cannot boot if it is the wrong version.

Hi all,
I am on:
- 02-06 nightly (https://download.lineageos.org/ido)
- ARM64 7.1 Stock GApps (http://opengapps.org/)

Camera app is not working at all, crashing instantly,

Do you know what could I have missed? Maybe not wiped correctly?
What could I do to troubleshoot/fix?

Thanks,

Answered: Inhibit Camera app automatic updates for the moment...

Hmm, never seen that one,
Just to be sure, you did the following steps:
- Restart computer as per section: Windows 10 "Disable driver signature enforcement"
[...]
- Reboot to recovery, power off, power on "Vol. up" + "Power"
- Touch "Download" button (screen goes black)
- Plug-in USB cable
- Open Miflash tool... (this I know you did cause of the screen capture)

Do you have any devices identified as not properly installed in the Window peripherals?
Maybe try and install Android tools (also in the tuto) before and try to issue commands to your device.

Also, Googling "ping target failed xiaomi" I found that: http://en.miui.com/thread-354050-1-1.html
You might want to use older tool version.

Let us know

Thank you for your time.

This worked !
Can't believe I didn't google my error thoroughly... Seems that the older I get, the lazier I become...

Just need to wait for the approval SMS now.
Thanks a lot for your help !

Maybe you did something wrong cause most of the people here on XDA have no issue.
Try using an older ROM, or clean install... let us know!

By the way, this is just a guide to flashing,
Which I believe was useful for you cause you were able to change ROM.

Don't report bugs/issues on the ROM here, it is just a guide, report them on the ROM thread itself: https://xdaforums.com/redmi-3/development/rom-cyanogenmod-14-0-t3481701

Hey guys,

I really do not know what to do.

with redmi one - i did not have problems - ok only one time

now I tried to put new international rom on my redmi 3 in holiday. I really treid it for at least 10 hours now! no success. I think, i am stupid....

flash unlock with sms and tool "miflash_unlock-en-2.2.406.5" worked.

next step is to power off and turn on with power up and power button.
If I do this, the redmi device always goes to fastboot picture rabbit and does not react to anything.

At this point I could not do anything. I always waited until accu was empty (1day) and then try it again in some other way.

Is there some really good guide? I do not know what i am doing wrong.

thank you in advance.

my redmi 3s crashed yesterday and i have the same problem now.
see here:
https://xdaforums.com/xiaomi-redmi-3s/help/phone-crashed-fingerprint-deleted-120-t3603930

for redmi 3 i downloaded a lot:
roms
02 MiFlashUnlock
03 TWRP
05 Root SuperSU

TWPR and RootSuperuser i do not get installed, too.
