I did just what you said not to do, I attempted to upgrade the firmware on my HAIPAD M701. I followed the directions exactly, (the ones on HAIPAD.Net) but I was unable to upload the tcc8900_mtd.img file. Now my tablet just sits on the initial screen, stuck. I am unable to turn it off except with the on/off switch. However, I am able to get it to flash, but it always refuses to download that file. And I am unable to do anything with the Recovery file. The FWDN doesn't support that type of file. Is there anything I can do?
