Root Changing Roms issue (issue fixed)

[Slikno420]

I've been switching roms and trying to find the one I like the best, however heres my issue. Ran the bat file to install Star-scrom, however I want to switch back to Prime Rom. But when I try and restore the backup in CWM I get the error message MD5 mismatch, how do I fix this?

Thanks in advance guys.

P.S. Also if you have the time and can explain what the MD5 is would be awesome, just so a noob can learn and maybe not screw up my phone again.

Cool, for future reference or for other peoples edification MD5 is a code that is generated based on a file thats called a hash.

It is used for several things from password encrypting to file verification but we tend to use it for file verification only. Basically no two files will have the same MD5 hash unless they are exact copies of each other. Change one bit in a file and the MD5 will be different.

In this way we can use MD5 to make sure the file has not changed since it was uploaded by someone.

Example:

Developer uploads a rom and with it includes nandroid.md5 (this is a text file list of all the MD5 hashes to be found in the roms files.)

You download it and put it on your phone and try to install it.

If it passes the MD5 check then the file was not corrupted in data transfer either from downloading it or from transferring the file to your phone.

If it fails it was corrupted during the file transfer, or like you found, renamed with spaces or funky characters.

This is a safety measure to keep you from flashing a corrupted file to your phone and bricking it.
