The firmware of Masik will continue to be produced with cut out components of ARB. If necessary, there is a safe way to go from ARB 3 to ARB 4 for Redmi Note 5 (Pro) https://sites.google.com/view/whyred-arb Mã: Whyred ARB Preparation: 1. Download the archive with the necessary components: https://yadi.sk/d/OUGZl1f43ahRvW https://drive.google.com/file/d/1pdGiAVvLGzk1-yXB5eOOsnJXCODEnRYi/view 2. Unpack the archive in any place convenient for you 3. Transfer the "Whyred" folder to the root of the C: / Installation: 1. We transfer the phone to the Fastboot mode (turn it off and hold down the "Volume down" and "Power" keys simultaneously, hold until the corresponding mode appears), connect to the PC 2. Launch the Mi Flash program, press "SELECT" and specify the folder "Whyred" on the C: / drive, then select the "Clean All" option in the Mi Flash options menu on the right (otherwise the loader will be blocked) 3. Press "REFRESH", then the connected device should appear in the list, then press "FLASH" 4. At the end of the firmware, the smartphone will automatically reboot into the system, you must enter Fastboot mode again 5. Go to the TWRP folder and run INSTALL.bat, after installation, the device will automatically boot into TWRP 6. Go to Wipe, execute Format Data, then Wipe Data + Vendor + System. If a format error occurs, you must restart TWRP Recovery and try again 7. Via MTP, we copy into the phone's memory the previously downloaded firmware and install it using the standard method Beginning with MIUI 10, Xiaomi developers introduced a special Anti-rollback system for Redmi Note 5, which blocks the ability to install older versions of MIUI, in addition, this may affect the installation of custom firmware. If you try to roll back or install custom firmware, you can get a "brick", so if you own this device, read the instructions on changing the status of ARB, possibly in the near future it will become a necessity.

Done, clip chi tiết các bước làm: Tin tưởng cách làm của Masik Dev Team. Cài lại Masik U final Whyred luôn, mượt mà quá.
