Xiaomi Mi5s Plus: install an official ROM or replace a "fake" ROM without unlocking the bootloader

Some of you will surely have noticed it our first guide explaining how to replace a "cooked" or "churn" ROM on the RedMi 4 Prime. Today it touches the Xiaomi Mi5s Plus.
With this guide we want to help you make the transition to the official ROM most suitable for us "no almond eyes", which already contains Google services and the Play Store and will receive the updates via OTA: Global Developer!

Let's see what we need and how to do it.

We are informed that on some devices it was possible to perform the procedure directly from the "updater" app, making this guide superfluous, so first try to install the ROM directly from the updater by following these steps:
  1. download the Global developer ROM directly from your smartphone from the following link, by clicking on FULL ROM: MIUI Global Developer ZIP version
  2. go to the app updater from your phone
  3. click on the 3 balls in the upper right and select "select update package"
  4. navigate to the path where you downloaded the ROM and click on the .zip of the ROM
  5. then follow the on-screen instructions to install the ROM

If, instead, the app updater reports an error in the package analysis, proceed with the installation of MIUI Global with the help below.

preconditions

  • perform all the operations with fully charged smartphones
  • the connection to the PC must be done without the use of HUB USB
  • the flash of the new ROM will result in the loss of all data: A backup on another device is strongly recommended
  • the guide is also working to install other official ROMs, provided in fastboot version
  • xiaomitoday.it assumes no responsibility for procedural errors

The Xiaomi Mi5S Plus, like other models, has the EDL blocked by the official 6.11.2 ROM, so if you have an official ROM next to this release, you can not follow the guide but you must unlock the bootloader to go to the Global ROM. If, instead, you mount a truncated ROM you can follow this guide because it will have EDL reachable.

Disable driver signatures on your PC (required for Windows 10 and Windows 8.1)

  • from the phone, go to settings -> device information and click 7 times on MIUI Version: in this way we will become developers
  • always from the phone, now, let's go back to settings -> additional settings (the second item, not the one under "hotspot" but the one immediately following "memory") -> developer options and activate the Debug USB

Now let's turn off signatures on your PC.

  • (if you have Windows 10 follow these steps and then proceed to the next step)notifications icon bottom right, click on all settings, then up upgrade and security, select the card for developers and choose the developer mode
  • (if you have Windows 8.1) restart by holding down the SHIFT key and, at restart, enter the TROUBLESHOOTING menu and then in ADVANCED OPTIONS
  • then click on START SETTINGS and then on RIAVVIA. When you reboot, you will be presented with one list like this below and you will have to click F7 by disable driver signatures. The PC will restart automatically

We install adb and MiFlash drivers on the PC

We just restarted the PC, then download the following files:
Download Driver Installation Tool Adb

Download ADB folder

Download MiFlash Ver. 20160830

Download MIUI Global Stable V 8.1.2.0 Fastboot version

 

now connect the phone to the PC and verify that it is connected in MTP mode (lower the notification curve and, if connected in "charging" mode, change it to MTP). At this point on your phone you will see a message asking you to allow USB debugging from your PC: before agreeing to it, we will post the box "always allow debugging USB from this computer"And then we give our consent.

Now let's start the driver driver installation tool (right click + start as administrator) and click on install as shown below:

tool-driver-adb

 

At the end we install MiFlash and when prompted to install the drivers with a warning, we consent to the installation of the drivers. The message will be repeated 5 times higher and we confirm it all the time.

Restart the PC and extract the ADB folder, copying it to C: /. You will have to have such a situation:

adb driver folder

 

 

Kedacom driver control before Flash

Go to Device Manager (on W10 just right-click on the Windows logo at bottom left) and make sure that with the phone connected to the PC in fastboot mode, a "Kedacom USB Device". [basically your Windows build does not recognize device drivers correctly]
Click on Kedacom USB Device and open the submenu. You should have Android Bootloader Interface. Right click on it and select "Update driver software ..", select search for driver software on your computer (option below), select search from a list of drivers on your computer, select version 7.1.0.0 and wait for the 'installation.

If you have problems, you can follow the procedure indicated by the following video demonstration.

Unplug the phone and restart the PC. Then check out Device Manager that your phone is no longer recognized as Kedacom.

 

You should have the phone still connected to your PC, so hold down SHIFT and click the RIGHT BUTTON in a white dot of the ADB folder and then select "open a command window here".

In the window that opens there, write it down adb devices and send date. You will see an alphanumeric string with the "device" next to it.

command window

If the words "unauthorized”Means that you have not ALWAYS authorized usb debugging! In this case, close the window, unplug the phone, go to developer options, click on “revoke USB debugging permission”, disable USB debugging, restart the phone, go back to developer options, reactivate USB debugging and reconnect it in MTP mode. You will get the message and you will need to check the box before allowing debugging.

Once the "device" message appears, we can proceed: write "adb reboot edl" without quotation marks and your phone will look dead, which means the screen will turn black, but it will stay on. Everything in the standard.

Now we have to extract with WINRAR (only with WINRAR I recommend!) ROM from downloaded .tgz file.
You will have a new folder with a name similar to this: "natrium_global_images_ecc etc" with a folder of images and other files inside it.

Be careful not to have two identical folders one in the other!

We then move the folder to C: / so we have the following path: C: / natrium_global_images_ecc etc /, even better if we rename the folder in C: / rom to shorten the path of the files (could cause an error).

How to flash ROM from MiFlash

start MiFlash, click on SELECT and select the downloaded ROM folder - point (1) of the image.

Click on REFRESH - point (2) - and a string will appear with code COM10 (3) We select clean all at the bottom of the program - point (4) - and let's wait for a few minutes to wait for a flash.

Click on FLASH (5) and wait for the process to complete.

miflash

 

When the program completes the operation, the phone will restart automatically (if it does not restart, hold down the power key and restart).

What to do now? Nothing, wait for the restart, and even if you are going to have a good deal of fun you can enjoy the full functionality of the ROM Global.

 

Flash problem resolution (can not read from this port)

If MiFlash gives you a similar error, the reasons may be:

  • you extracted the ROM into a folder with spaces in the name or in a folder with the same name as the one in which it is contained (just move the ROM)
  • you WINDOWS 7 and you have not disabled verification of driver signatures
    (restart the PC: during Windows boot, press F8 and the screen below will appear Select FIRMA DRIVER SETUP DISABLED and the PC will restart Proceed with the flash from Miflash as a guide without reinstalling the drivers b) - NOTE: THE SETTING IS DISABLED UP TO YOU DO NOT REACH YOUR PCwindows 7 driver

 

I hope I have done what you like and I remind you that you will soon see other similar guides like this but for other Xiaomi devices. A good news no?
