Need help desperately

[guitarboy0211]

Hello people, I don't know if there's anyone out there who still use the G pro but here I am still using it. Okay so I have been stuck with this problem for almost 2 months now, I rooted my phone amd everything was great till the time I tried to install a custom recovery using freegee. It did not work. In the beginning, it said my phone wasn't compatible because of some loki **** but I still went ahead with it anyway.

So after I installed the 2nd-init recovery, it automatically made a backup of my stock rom but after I rebooted, things went bad. My phone was okay, sort of. The main problem was that my memory card stopped working and my phone began changing settings itself like turning the wifi off, screen on changes to 15 seconds and it keeps doing this again and again and I have to keep changing the settings.

Can somebody please help me fix this issue as I really can't take this anymore. I cant use my phone properly any longer. Oh and my phone is still under warranty but m scared to give it in as I feel they might find out it was rooted or some ****. Is there anyway I can get back to the old recovery and remove this 2nd init ****? i can locate the file bt im scared to delete it as i wouldnt wanna wreck my phone any further.
