my friend's phone had an error on his phone(Acer z160 not rooted), all the applications crash at start-up. It came to my mind that I had to do a factory reset via stock recovery. After the reset, I restarted the phone and the error was still there. I decided to flash the stock ROM (Acer_AV052_Z160_1.015.00_EMEA_GEN1) using the "SP_Flash_Tool_exe_Windows_v5.1516.00" and the flash was successful. Rebooted the phone again, and the error was still there. In fact, the phone's password/pattern is still there, the wallpaper hasn't changed and apps are still there. What happened? What should i do? Could you please help me. Any help would be appreciated
That means your device's eMMC is (Write Protected), Which means that it won't accept any changes you do, This is a common problem in MTK based devices, Actually you have to replace the eMMC chip by a new one, But you can also try this,
- Run SPFT and Load "Scatter" File,
- Go to "Format" tab,
- Don't mess with any options there,
- Click "Start" then Plug your phone,
- Wait until the Format process finish,
- Now just try to flash the phone again with SPFT,
NOTE: After this process your phone won't have IMEI anymore, But that's not a problem since there is a lot of ways to restore it, Just check this Video.
If the above guide didn't help fixing your phone, then as i said before, eMMC needs to be replaced.
