Hi

I bought a xiaomi redmi 3 from china.
It had the google play store pre-installed, however the play store doesn't work (I can log in once with my account and after that I keep getting errors saying 'verification needed, please log in with your google account". My accounts don't synchronise. Also I am not very happy with the battery of my phone, it seems to drain pretty quickly. I expected more with this size of battery...
I've contacted customer service of the webshop I bought the phone from and they told me to "flash ROM to phone".
So, I don't know anything about all these ROMs and everything.
Can someone please give me a step-by-step guide/explanation to flash a new ROM to my phone? (or a link to a very detailed and understandable website explaining all this)
I'm afraid I will do something that can't be undone and my phone will become useless.
Also, how can I make a back-up of my old ROM?

I really hope someone can help me with this,
thanks in advance

Hello, search in internet, there are many guidelines.
Not the easiest is if you have never done
Try patiently
 
Can I flash ROM with the updater app? Is the latest version (6.7.21) stable? does it function well?
How can I make a backup of the old ROM? (without having to root my phone?)

I really need some more advice...
It's hard to search the internet if you don't know a lot about al this ROM stuff.
There's to much information to be found online, I kinda get lost...

Hello
1) Setting, About phone > write MIUI version
2) your bootloader is unlocked?

I hope someone follows you, I do not have time today
 
I have MIUI version 7.3.2.0.0.
I have done nothing to my phone so far, so no I dont think bootloader is unlocked.
 
Hello,

I have mostly same issue. Google Play didn't work so I deleted my google account from the phone and now I can't add it back. I have same MIUI version. I looked for ways to flash to a newer ROM and failed in all of them:

1) I've downloaded a Stable ROM at http:__en.miui.com_download-298.html. Then I put it on a device and ran Updater app. The device rebooted but nothing changed.
2) I've downloaded MiFlash but it seems it's the wrong kind of file for MiFlash and there's only Chinese ROM available for MiFlash.
3) I've downloaded MiSuite (both Chinese and English) but it puts up an error message when I put my phone in recovery mode and doesn't start an update. Even though it detects my phone when it is booted normally.

Please help.
 
your help is really appreciated but im sorry to say that i still dont understand :(

- how do i backup my old rom
- which rom must i install? I want a european version with my own language supported. i want to have one thats good and that i dont have to change again
- so i unoock bootloader and then what?

i thought the phone would be good with normal functioning software, ive contacted customer service of the webshop as well and they are not helping me so far
all these things are probably very obvious to you but i am not screwing up my phone doing things i dont understand
Im a complete noob with these things, could anyone please explain in the simplest terms, step by step what I have to do?
I would be forever thankful

First you must flash a official rom to unlock your bootloader, today a official global rom is available. You can flash this rom to unlock bl.
 
I also found out trying to first flash the official China development ROM (and properly also the just released official global ROM) for the redmi 3 pro FAILED via the updater app. I downloaded the zip file (China development full ROM) and select it via the updater app. My phone reboot, for some time I only see MI logo and reboot again... It just boots into the unchanged vendor ROM again... See screenshot of the version.

I really need to get this working before I can unlock my bootloader. Please help, it's not my first time I am flashing ROMs (did it before on HTC desire & Samsung Galaxy) and I'm a software engineer. So I'm not a noob, still this looks like a blocking issue.

The official global is not yet listed here: en.miui.com<slash>download-298.html (omg stupid 10 posts rule)

But I found it on the forum.
en.miui.com<slash>thread-318059-1-1.html
(sorry I can't post links, after 10 posts I can)

This one?
and how do I flash it?

I have to flash a rom to unlock a bootloader to flash a rom?

Hehe yea. Well you need to flash an OFFICIAL rom, then unlock the bootloader, before you can flash a NOT official rom. You point to a not official rom (this is the unofficial global European rom from xiaomi.eu) . In fact every rom provided on xiaomi.eu is unofficial. You get it?

Thanks that works perfectly. I'm now running MIUI 8 (v6.7.28 Beta) on my Redmi 3 Pro.

I'm a developer myself, I can understand the trouble you go through if you aren't a developer or never did a rom flash.

NOTE: I can't still not post links in this forum (plz admin give me the rights to do so). So remove the SPACE after '.com ' so the links do work for you!

What I did so fair is:
  1. Using Windows 10 Pro 64 bit
  2. Fill-in the request form to unlock the bootlocker at: en.miui.com /unlock (it took 3 days I think before I got an approval back)
  3. Be sure you use the same Mi Account for unlocking request (step 2) as when logging in into your device using the same Mi Account.
  4. Downloaded the Flash tool (called MiFlash) from: xiaomitips.com /getfile/1474/
  5. Downloaded also the latest official china development rom (Fastboot, with the extention .tgz): update.miui.com /updates/v1/fullromdownload.php?d=ido_xhdpi&b=X&r=cn&n=

    OR Download directly the Global Development rom (fastboot) from:
    bigota.d.miui.com /6.7.29/ido_xhdpi_global_images_6.7.29_20160712.0000.26_5.1_global_53ec8fd6fc.tgz

  6. Since some drivers are needed which may be not installed yet on your Windows computer. We need to set your computer in 'Test mode' in order to allow you to install such drivers. Do the following steps:
  7. Open a new CMD terminal under Windows, search for 'CMD'. Right click -> Run as administrator.
  8. Execute the following command:
    bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
  9. Then execute a second command:
    bcdedit.exe -set TESTSIGNING ON
  10. Reboot your computer. In the right bottom corner in your background wallpaper you should see 'Test mode'. Now continue.
  11. Extract the .tgz ROM file you downloaded at step 4. Extract the tar inside again, into a good location (like C:/ROM). See my the attached image (extracted.png) how this looks like.
  12. Now open the MiFlash tool as well, see yes to all questions.
  13. Shutdown your mobile, start your mobile in recovery mode by pressing Power up button + Power button (at the same time).
  14. It could be you see characters in Chinese, press the Download button in this menu. You could change the language to English by clicking on the almost bottom right button.. grr, this is horrible to explain in text. So see the image I attached where the Download button should be. Click atleast on this Download button, your screens goes black (that is good). See download_button.jpg in the attachments.
  15. Attach the mobile to the computer via a USB. You should see Qualcomm HS-USB .. in your Device Manager of Windows. See attachment as well (device_manager.png)
  16. Open the MiFlash tool, browse to C:/ROM (NOT C:/ROM/images). Press the refresh button to see the attached devices (COM3). See miflash.png.
  17. Click COM3 and press the ''Flash"button. Finally the ROM will be flashed to your mobile phone. Do not unplug the mobile phone from the usb!
  18. When you see succeed in the MiFlash app you are ready to unplug the USB. And hold down the power button until it vibrates.
  19. The mobile reboots, it can take a while (SEVERAL MINUTES), until the initial loading is done of Android.
  20. You can login with your Mi Account again and continue to setup your phone.
  21. You are your almost done... Let's continue later when you are this far :D....

    Ps. step 19 can take really really long, up to (or more then) 10 minutes. So be very patient.
