If you encounter any issues while flashing the stock rom, you can try the following solutions:

• If SP-Flashtool does not detect your device, make sure you have installed the MediaTek USB VCOM drivers correctly and try using a different USB port or cable.
• If SP-Flashtool gives you an error message, such as BROM ERROR or STATUS ERROR, make sure you have selected the correct scatter file and try changing the download mode to “Firmware Upgrade” or “Format All + Download”.
• If your device gets stuck on a bootloop or does not boot up at all after flashing, try performing a factory reset from the recovery mode. To enter the recovery mode, turn off your device and then press and hold the power and volume up buttons until you see the Wiko logo. Then use the volume buttons to navigate and the power button to select. Choose “wipe data/factory reset” and confirm. Then choose “reboot system now” and wait for your device to restart.

If none of these solutions work, you may need to flash your device with a different stock rom or seek professional help.
