[Android Q&A, Help & Troubleshooting] toBsucht Psp:
Since i just found some request about rooting and custom recovery of C variante of Archos 50 platinum on xda. I decided to make a thread which works with both variantes 8 or 16GB and all firmware.

I installed TWRP 2.8.7 from Source

to a device with firmware:

BSE70M_ARCHOS_AC50CPL_20160829_V05@ARCHOS.201116.140537.Euphoria
Build fingerprint: archos/SCAC50CPL/ac50cpl:5.1/LMY47D/20151116.140537:user/release-keys
Platform: armeabi-v7a, 32-bit binary

and to a 2. device
BSE70M_ARCHOS_AC50CPL_20160829_V05@ARCHOS.201116.140537.Mesarthim

Today i saw, it seems like Archos provide two firmware for the SC7731g Euphoria or

Mesarthim (OTA pac download see below). Run firmware check OTA update 2x befor rooting to get latest - V05.

Firmware checkbox:

Mesarthim firmware

Root + TWRP via adb

If you done setup on your device, save a full backup with twrp ;)

Driver and tools:

Keep in mind you have to install needed debugg usb-driver and fastboot (adb)

or use other tools as SPD upgrader tool + SpreadTrum driver.

Fastboot installer and driver:

Fastboot as Live boot image

With twrp you can now install latest superuser to manage superuser authorization or xposed.

uninstalled superSU, now i use magisk

Switched back to supersu less bugs with xposed. The patched boot.img can be used to enable root if Archos update firmware

Do not blame me for any damage while installation ;)

If you get into trouble booting your device. You can try

1. a) fully power it off by press Power off 10sec. or b) remove battery.

2. Copy V05 or V08 update.zip depents on your installed firmware to your Archos and reinstall firmware by apply message if usb is unplugged. Any flashable .zip get auto detected and became deleted from internal storage if not orginal.

3. flash update.zip via fastboot mode. (in case bootloop you maybe fastboot via button on boot into bootloader or adb)

4. flash stock rom pac file from update.zip to Spreadtrum Chip device via factory downloder +(driver) Download extract pac from .rar part 1 part 2

5. now you can flash via twrp my aroma rom if any needed stock app is missing. (see 2. post)

6. Flash v05 stock recovery = unroot

7. restore TWRP back :o) if you did not do that 1st (o:

Inizialize twrp or superuser first time maybe take up to a minute and a reboot ;) :cool:

Alternative way to get root & twrp:

Not test by myself but seems to work:

Extra stuff > # TWRP lock, dial engineer mode, videos

Password protection for TWRP (lock) with https://xdaforums.com/xperia-z2/general/lockable-twrp-recovery-t3151283

To improve media handel (video rec. buffer, i´m not 100% on it) maybe replace codec_pga.xml of attached archiv on root floder \system\etc\codec_pga.xml

As far as i know it´s possible to swap a faster sd as internal memory to improve read and writte speed by tools e.g. Root External 2 Internal SD.

Dial: *#*#83781#*#* Open engineer mode ;)

Camera (13mp) replacement is works (easy)

Just open housing by removing battery and screws, cam-cabel can be unplugged as simple as in b-versions display-cable :p

Today i wasted a lot time by try to flash a stock rom to SC7731g device. Now i got it :cyclops:

Chip can be checked under settings / about phone / Baseband version /

or by installed firmware ;)

Download and install driver and SPD Upgrade Tool R2 or up. Then it is important to hold Volume down (-) if you connect usb to flash files, otherwise you get a CANCEL message! If SPD tool start download no need to hold volume down.

factory downloder +(driver) Download update.zip with pac file inside from 4pda.ru forum. If you flashed stock firmware by flashing tool. Install OTA V10 run update check again and install latest update befor flashing TWRP.
