i just jailbroke my phone and installed a few apps, but now when i open cydia all the repositories are gone and i dont know how to get them back. my phone also keeps entering safemode but i think thats because i have bitesms 5.0 and not 5.1 that is compatible with 4.2.1 (which is the fw version i have). i want to update bitesms but now it seems like i have a bigger problem. any help? thanks!
