I just wanted to say thank you so much for these great instructions! I managed to unbrick a totally trashed Cubot H1 by following these instructions to the letter and using the correct ROM for the phone - which I got on another site.
I don't find the SP Flash Tool very intuitive to use and I didn't realise that you had to press download first, then attach the phone. I just thought that my phone wasn't being recognised. This step by step guide made me see that I was doing things in the wrong order and that it wasn't that my phone wasn't being recognised. So thank you!!
I was honestly at the point that I was going to throw the phone in the bin, and now it is working perfectly.
Just some advice for anyone else having the same issue - you have to get the exact ROM for the Cubot H1 - if you try to use any other ROM, even ones that are roughly right, like the Cubot H1 R1, it will not work!
All this hassle just because I rooted the phone to get the iOS icons on my Android! Doh! :p
