bencebacsi

This is an unofficial SP Flash Tool release of the

V1.0_20171207 Basic Edition (UMI OS 2.0)

system software for

UMIDIGI S2 Pro

Flash tool operation is recommended for experienced users only. Do not use it if you cannot understand the whole process!

WARNING!

If you have this version installed on your phone, your warranty might be voided according to your seller's policy! In case of a warranty return, we recommend you to flash an official stock ROM.

If you have this version installed on your phone, OTA updates cannot be installed. Basic Edition version OTA updates will not be provided. You can any time return to an official stuck ROM (flashing only the system partition of the same version is enough) to be able to receive factory OTA updates again.

If you flash the Basic Edition version for the first time, it is highly recommended to flash it in Firmware Upgrade mode (your user data will be erased) in order to remove the updates and saved data of the removed apps as well. Later updates can be flashed without the userdata partition.

Changelog:

• Replacable default launcher (once you set it as default, you must uninstall your custom launcher to be able to use the system launcher again)
• Initiator launcher replaced by Google Pixel launcher as the system launcher
• Not system-sensitive custom apps have been removed
  

         List of removed apps: 360 Security, FreeShare, QuickTouch, TouchPal 2017, App Store, Intelligent Aggregating Page, Power Master, 9Apps, News Republic, UC Browser, Avatar Master, Anti-theft, App Cleanup, Initiator (system launcher), Property System, 360 Clone

Here's an optional solution to start the flashing process on your UMIDIGI S2 Pro if the standard method doesn't work.

It's especially useful if your phone is bricked or is stuck in bootloop

1. Connect your UMIDIGI S2 Pro to USB.

2. Start the flashing process with the Download button in the flasher app.

3. Press and keep pressed the power button of your phone until the flashing process starts (red bar appears at the bottom of the app window), then release it. In this process you have to keep the power button pressed for about 10 seconds.

4. Wait until the flashing process finishes.
