UMIDIGI S2 V1.0_20171221 ROM - SPFT + OTA release

Post time 2017-12-26 15:20:39 | Show all posts |Read mode
This is the SP Flash Tool + OTA release of the
V1.0_20171221 (Android 6.0.1) system software
for UMIDIGI S2

Flash tool operation is recommended for experienced users only. Do not use it if you cannot understand the whole process!
UMIDIGI S2 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:
  • Optimized camera performance
  • WiFi stability issues fixed
  • Minor bug fixes



--------------------------------------------------------------------------------
SP Flash Tool
Resources:

Extract the .rar file before use. The scatter file (MT6757_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 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 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 either the internal memory or the SD card of your phone
  • Go to Settings --> About phone --> Wireless update
  • Tap the 3-dot menu button at the top right corner and select Local updates
  • Brows for the ...update.zip file and select it
  • Tap Install now, comfirm the process with OK and wait until the process will be finished

Update file for manual OTA update: >>>>> UMIDIGI_S2_V1.0_20171221_update.zip <<<<<
It can update version 171027 and 171123 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 recovery mode. It needs about 10 seconds or a little bit less if your phone was already powered off.
  • Here you can see a lying android figure with an exclamation mark in red triangle on its tummy and ''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 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.

I still can't change ISO and Shutter Speed. Are you going to make it possible? Are you going to make frame rate more than 13 fps for 4k video?

What can you say about manual ISO and Shutter speed?

You can change the ISO speed in pro-photo mode, that feature was always available. The shutter speed will not be manually changeable. I don't know how many smartphone models you know, that makes it possible to manually change the shutter speed. The video framerate is not limited to 13-14fps in 4K resolution. I don't understand why you repeat that again and again. Here's a 4K video recorded with an S2 in a hardware store. It's average framerate is 27fps.

As I told you earlier (and you also can read it out from the file information), the video encoder uses dynamic frame rate; the lower the shutter speed, the lower current fps.

1. You are right my friend! Look at the screenshot of YOUR footage properties. 13.87i means INTERLACED VIDEO! It is not PROGRESSIVE scan! That is why you see 27 fps in the windows properties and 13.87 fps in Adobe Premiere Pro. Look at your own footage, it is not smooth. It jerks from frame to frame.2. I see visual artifacts in your footage: horizontal lines at the edges of the screen. Do you see them? I have the same on my phone.

3. I can change the ISO speed in pro-photo mode, BUT that feature doesn't work properly! When fixed ISO selected (100, 200, 400...) the camera is still changing brightnes of the picture.

4. I know for sure that every iPhone since 10 year old 4s model has ability to manually change the shutter speed using filmic pro app. Many cheap android phones can change the shutter speed in Camera FV-5.


I hope you can give us a clear answer about each of these 4 issues. And tell us what and when you can fix in the next firmware.

Edited by esclusoilcane at 2017-12-27 19:19 \n\nIt seems to me overall more stable, obviously not miracle in camera but less blurry in pictures and more stable, so decent ones. Better overall functionality and until now no crash nor in YouTube ,nor in WhatsApp like before
I'll keep u updated
After 1 day of usage with this update i'd say: nice job for a200$ phone
Still to test in my everyday usage: floatify stability after longer usage (frequent crash before), recording WhatsApp messages after unlinked Bluetooh (mute before)
