UMIDIGI S2 Lite V1.0_20180202 ROM - SPFT + OTA release

bencebacsi

This is the SP Flash Tool + OTA release of the

V1.0_20180202 system software

for UMIDIGI S2 Lite

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

UMIDIGI S2 Lite 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:

• Face ID bug fixed
• Improved front and rear camera performance
• Increased battery charging power - shorter chargeing time
• Further minor bug fixes

ROM: >>>>> C350_KW_S83C_201802021854.rar <<<<<

Extract the .rar file before use. The scatter file (MT6750T_Android_scatter.txt) is inside the extracted folder, together with the other components

VCOM driver: Windows 10 already automatically can install it or you can use this: MTK_Driver_Auto_Installer_SP_Drivers_20160804.exe

Here's an optional solution to start the flashing process on your UMIDIGI S2 Lite 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 Lite 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.

OTA (recovery) update

Manual (local) OTA update method instructions

• Copy the downloaded .zip file to the internal memory of your phone
• Go to Settings --> About phone --> System update
• Tap the 3-dot menu button in the top right corner and select Local Updates
• Brows for the ...update.zip file and select it
• Select Restart now. Your phone reboots into recovery, the update gets installed, then your phone boots into Android. Your updated system is ready to use.
  

Update file for manual OTA update: >>>>> UMIDIGI_S2_LITE_V1.0_20180202_update.zip <<<<< It can update version 20180124 and 20180126 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.
• 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 the 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 sdcard 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.

WHEN UPDATE TO  UM OS   FOR THIS VERSION

UMI OS has been discontinued and you shouldn't regret it. This model will receive a stock android 8.1 upgrade planned in May.

Hi,
If you mean the fingerprint touch functions, they are not available in S2 Lite. However, there's a workaround since the fingerprint sensor is assigned as a camera button in the system. Install Buttons remapper, then you can assign short- and long-press actions to the fingerprint sensor with it. In the list of keys select CAMERA.

Currently it's not planned since even if new devices would've been shipped with stock Android, the existing phones with UIM OS couldn't be changed to stock Android since the Efuse protection makes it impossible. At least our current knowledge tells that.

Hey,
I updated my phone to this update via OTA which appeared to of worked perfectly then i installed a app(Lastpass) which informed me my phone was rooted, i havnt rooted it. so i used the SP flash tool to reflash the os, that all worked perfectly but its still saying the device is rooted, also my banking application wont allow me to use the finger print sensor because of the rooting issue, is there a specifc reason for this? or some way i can fix it?

Thanks,
John
