Help Pls. I think MD5 file is important. Thanks in Advance!!!
my phone specs:
An "MD5" file is a hash file that is used to verify that a download was successful (well, in this case, not in all cases. I use MD5's in some of my code for authentication so I don't need to store usernames and passwords in my database. An MD5 is harder to reverse engineer (especially if I salt the username and password pair) than a plain text username/password pair thing). If you go to the webpage in your browser for the ROM you are downloading, goo.im's website lists the MD5. If you go into shell on your phone and type in "md5 " followed by the name of the file you downloaded, it will tell you the MD5 of that file (you may need busybox). If the numbers match between shell and the website, you are good to go and can disable the MD5 check in recovery. If they do NOT match, you have a bad download and will need to re-download it.
Wiping caches shouldn't care about an MD5 as there is nothing to compare. Backups and restores and zip flashes care about MD5's as if you have a bad download (or bad backup or bad restore) you can brick your phone.
for more information on MD5's, look at the wikipedia page:
