If your iPhone cannot connect, replug or change a different lightninng to USB cable, you'd better use the brand cable.
If your Android cannot connect, make sure you enable USB debugging on the phone or change the USB connection mode.
You can try to another method instead. Back up WhatsApp on your source device with WatsGo first and then choose to restore WhatsApp backup to your target device. If you still cannot transfer, please contact us ([email protected])and we will reply within 1-2 days.
WhatsApp data will be backed up to the local on your computer. Please make sure there is enough space on your computer. It won't back up successfully if no space is available.
Currently, iToolab WatsGo does not support any modified WhatsApp apps: WhatsApp Plus, WhatsApp Go, GBWhatsApp, YOWhatsApp, FMWhatsApp, WhatsApp Aero, OGWhatsApp, WhatsApp Prime, WhatsApp MA, WhatsApp Indigo, GBWhatsApp Mini, Soula WhatsApp Lite, etc.
But iToolab team is working on it right now and will support some of apps in the near future.
