OMG i been triying for months to get away my reset loop problem on my s621!!
AND THIS DRIVER DONE IT!!!
I had to remove my 2gb sd card (fat32) every time i reset, was anoying because if i took much time to insert it had the storage card2 bug (really really anoying)
Omg im so gratefull, i read a lot of times that bug involve the omap850_sdhc.dll but on my device cant be renamed or replaced.
I just apply the pacth and done! now i can reset turn it off removing battery or at any metod and no more reset loop
P.D. I dont know if work on sdhc for me (i guess yes) so i dont have any sdhc to test
Ill gonna put a link to here on every loop forum ive visited.
