bencebacsi

This is the SP Flash Tool + OTA release of the

V2.0_20180920 system software

for UMIDIGI A1 Pro

Flash tool operation is recommended to experienced users only. If you are not yet an experienced flash tool user, please carefully read the flash tool tutorial before proceeding, and strictly follow each instruction.

Except if an authorized or responsible expert directly asked you to do that,

never format the flash chip of your device or you instantly lose your warranty!

UMIDIGI A1 Pro receives all updates automatically via FOTA method. You need this tool only in case of emergency (if you've bricked your phone), if you want to apply a clean install or if you want to clear all root access and custom recovery to make your phone able to receive FOTA updates again.

Changelog:

• Navigation bar customization added to Settings
• The fingerprint scanner is addressed as F10 button when the phone is unlocked
• Fingerprint scanner haptic feedback (vibration) force increased
• Waze app crash bug fixed
• Improved bluetooth stability
• Othe minor bug fixes
• EngineerMode removed permanently by Google's request (GMS certificate criterion)
  

FOTA version: UMIDIGI A1_PRO_V2.0_20180920_20180920_2303

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

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.

OTA (recovery) update

Manual (local) OTA update method instructions

• Copy the downloaded .zip file to the internal memory of your phone
• Go to Settings --> System --> About phone --> Wireless update
• Tap the 3-dot menu button in the top right corner and select Local Updates

It can update version 20180601 only

Optional method (in case if the manual OTA update gets stuck): Install from recovery

You need a microSD card (with at least 4GB capacity) installed in your phone!

• Copy the ...update.zip file to your SD card.
• Press and hold the volume-up and power buttons together until your phone restarts in the boot selector mode. It needs about 10 seconds or a little bit less if your phone was already powered off.
• Here you can move with the vol-up button and select an item with vol-down. Select Recovery.
• Your phone boots into Recovery and you see a lying android figure with an exclamation mark in red triangle on its tummy + 'No command'.
• Press and hold the power and vol-up buttons (in this order) together, then release them to call the recovery menu. Now you can move with both volume buttons, and select an item with the power button.
• Move to ‘Apply update from SD card’ and select it.
• On the next screen brows for the update file and select it. The updating process will start and needs a few minutes to be finished.
• After a succcessful installation you can read the ''Install from SD card complete.'' message and the receovery menu is available again.
• Select 'Reboot system now'. Alternatively you can perform a factory data reset here by choosing 'Wipe data/factory reset'
  

Kind request from users:
Please report any kind of new issues you experience after installing this update only if you've already flashed this ROM with SP Flash Tool in Firmware Upgrade mode. In rare cases a FOTA update can cause more or less serious malfunctions but that means only the update process went wrong, not a badly developed ROM. An updated stock ROM, especially related to the basic functions will not cause any new issues but will solve some of the existing ones.

Can I revert to UMIDIGI_A1Pro_V1.0_20180601 or install engineering mode apk ?

The EngineerMode app has been removed permanently by Google's request. It won't be available in any new software versions of any Android based smartphones. You can flash an older version with SPFT or you can just simply perform a factory data reset. The EngineerMode was never officially supported, from now it's not even available.

Hello, since this update I do not have access to engineering mode. This is a big problem because the sim card is locked in 4g lte only, I cannot make any calls (requires umts). *#*#3646633#*#* gives me system logging feature but no engineering mode. How do I switch back ?
