lost all my apps and games after rooting <fast help please>

if you rooted AND unlocked your bootloader, yea, you will lose everything. no way getting around that.

as for the restoring part, perhaps you should ask that question in the Applications section of this forum. or better yet, contact the developers directly for assistance.

 

you can not root any device and keep your warranty. BUT if you ever need to claim warranty, just unroot and re-lock the bootloader before sending your device in.

for backing up contacts and calendar, just make sure those are synced to your google account.

but for apps, without root, you can't reliably backup app data/save. you can backup the app itself (the APK).

 

not too sure on this, but i believe you will always lose data whenever the bootloader is involved- both locking and unlocking.

when rooting and unrooting, (the bootloader has to be unlocked no matter what), depending on the method, you might be able to keep your data.
