Evening, i successfully rooted my desire last week then decided yesterday to go a step further and install a custom ROM with ROM Manager which seemed to work. however i didnt like it so i tried to revert back to my original one. since then i have been stuck in a boot loop. the recovery shows that it is doing something but it then says right at the end that the sd-extimg hasnt worked or something hasnt worked. i have also tried inserting my sd card into my pc but it wont read it. now u have an android picture with a triangle with an exclamation mark in it on the screen. can anyone plese please help?
