esto es absurdo , he seguido este tuto en slatedroid y me ha funcionado!
My steps to revive mine and is very similar to others using Windows Vista 64 bit + WinImage + HP Flash Format Tool.
1. An external (AData) microSD 8GB.
2. Format (DO NOT USE QUICK FOTMAT) it using HP flash format tool.
3. Use winimage tool (v16.1): from winimage menu "Disk->Restore Virtual Hard Disk image on physical drive..." select the 8GB microSD card (corresponding device), then pick file "INand_mm_sd_mbr.vhd". Note that I am actually using the Evolution 2.0 R6 rar file content.
4. It would be done in a flash literally and I wasn't even sure it did or not, so go to Windows Disk Management, you will see the microSD card now has multiple partition.
5. Remove and insert microSD card and Windows would prompt you to format the drive. Click Yes/OK.
6. Once formatted, copy all files from the extracted Evolution 2.0 R4 rar file or your choice of ROM.
7. Insert microSD card into Dropad and press power with "M" button.
8. Device should boots and perform firmware "upgrade"
9. It then shutdown when it is done.
10. Use the physical switch to turn off and take the external 8GB microSD card out.
11. Turn it on again and it works for me.
