so ive been trying to figure out how to unroot my hero and ive tried using the 1.29 RUU but keep getting the 140 error. ive looked all over the internet and cant find any solutions on how to get it working and i was wondering if anyone here knows a solution or another method to unroot. i also had 1 other problem i wanted to restore my nandroid backup so i can return to the stock rom if i cant unroot but i keep getting an error that says "Error : run 'nandroid-mobile.sh restore' wia console!" and i tried searching that but i cant find a solution either and wanted to know how to get the restore working or where i can get a stock rom that i can use. any help would be greatly appreciated
