TWRP for sc7731c hope it helps

hi all a have a sc7731c phone on android 6.0 and i was able to install twrp on my device

it all started when i found a stock rom on the web (Google your device for stock - rom or - firmware)

once i had the rom i started searching for a way to extract the stock recovery from the rom

and i found this tool SPD_Upgrade_Tool_R4.0.0001 using this tool i extracted my stock

recovery from the ROM ( recovery.img ) , first stage complete i had a stock recovery

taken from a rom for my phone - brand and model must be right on the stock

firmware/rom or you risk damaging your phone (DO NOT CHEAT PLZ)

ps:when you unpack the firmware/rom you should get a .pac file

ps:finding my stock rom took me several days of search.

now for STAGE 2 i had a stock recovery a needed to change it

for twrp another few days of search i came across a site

called hovatek here i found a tool to port (change) the

stock recovery to boot the twrp recovery the tool name is

[Hovatek] Spreadtrum (SPD) Auto TWRP Recovery Porter V1.0 by Team Hovatek (x86)

i PORT my stock recovery with this tool the tool creates a modified recovery on the

output folder( a few kb bigger ) stage 2 done.

STAGE 3

1- a fully working ADB, for this your best option is android-studio

2-turn on USB debuging and OEM unlock in DEV options

3-name the new recovery file recovery.img

4- place the new ported recovery.img in the adb

installation folder ( c:\platform-tools-latest-windows\platform-tools )

5-your device has to be in USB MTP mode

6-if ADB is properly installed and Windows has the correct android device

driver you should be able to use these commands using android-studio's ADB

command- adb devices

-if the device is detected a serial number apears

command- adb reboot bootloader

-the device reboots to a black screen with small white letters saying FASTBOOT mode

command- fastboot devices

-the device displays the serial number again

command- fastboot flash recovery recovery.img

- if all went well it will say successful

command- fastboot reboot

-dont remenber if it booted straight to twrp or if i had to use power + volume up

-by the way on my phone to get in the default recover its 1 second hold power

and then with the power pressed for 1 sec add volume up 3 sec and let go of both

any way it worked i hope it helps ppl with these sc7731c phones

i have twrp 3.0.0 fully working (My Model - Selecline/Auchan s6s4in3g)

tips: youtube vídeos on how to use SPD_Upgrade_Tool_R4.0.0001

the hovatek site has a great tutorial on how to use the recovery porter tool

the last part the ADB commands was a ***** as Windows did not install my device

correctly and this is crucial -install phone driver manualy/Google device/Google android device. good luck

ps: all merit goes to the developers of these tools, a great ty to them

ps: at the start i did NOT have root, the success flashing the ported twrp recovery

was followed by the installation of the magisk15.3.zip and voila twrp+root

Here is a Ready twrp 3.1.1-0 recovery for SELECLINE/AUCHAN S6S4IN3G

(WARNING)do not flash it on any other brand or model IM NOT TO BLAME
