Problem solved:
branded cable from rock charges the phone, but pc can't recognise the phone
no name cable which i borrow from neighbor ....working
i use this steps, to overwrite twrp 3.3....with OrangeFox-R10.1_3-Stable-violet
- Download the correct OrangeFox zip file
- Extract recovery.img from the OrangeFox zip file, and copy recovery.img to your PC’s adb directory
- Unlock your bootloader (skip if already done)
- Install drivers and open up a command line window / terminal emulator on your PC
- Next, switch off your phone and reboot to fastboot mode. [Press and hold Power+Volume down button together]
- Go to the installed ADB Folder on your C drive.
- Copy the recovery image file on the folder as well.
- Now, press Shift key + right-click in the blank area inside the ADB folder.
- You will see the open Command Window here option. Launch it.
- Now, type the following commands in the command window and press enter:
- fastboot devices
- fastboot flash recovery (drag recovery file from folder here and hit enter)
- when it is finished (look at photo 1) Press and hold Power+Volume UP button together]
- Reboot in recovery by pressing vol UP + power keys till you will see OrangeFox splash (the keys may be may vary on your device)
- After OrangeFox has booted up, check that everything is working – eg, that it has mounted the data partition successfully, and that the touchscreen works.
- copy OrangeFox-R10.1_3-Stable-violet into your phone
- Find and select the OrangeFox zip, tap on it, and swipe to install it (because OrangeFox Recovery needs some files from the zip)
- After installation, the phone will automatically reboot into OrangeFox
- Enjoy!
