I don't know if this is the correct place to write this, but if not please advise me as I'm new in this fields.
Some time ago I decided to root my Jelly bean HTC One S (S4). To do that I used the HTCDEV method and follow this post step-by-step witch I thank to all developers involved: http://forum.xda-developers.com/show....php?t=1583427
It worked well and the only thing I done different was installing TWRP 2.6.3 recovery instead CWM.
Lately I decide to install a custom kernel (Bulletproof 1.4), essentially because I wanted to fix refresh rate/crash of HDMI output among other good things that this kernel provide. Here started my problems. I download the zip file, file copy it to phone memory through usb and then restart the phone to bootloader, enter in recovery and flash it with TWRP. After that my phone don't boot and was stuck in bootloop.
As I previous made a backup of my system through TWRP I thought it would be enough to restore it, but then my sdcard was unreachable and I found no way to access it. At this point I had also the copy of the backup I done with recovery in my laptop. With the phone in bootloader screen (witch I'm still able to reach) I can see the phone in devices although not accessible. So the only way I found to fix my phone was format the sdcard though windows copy the backup to sdcard via and then make make a restore via TWRP. It somehow worked and I was able to back to system.
I checked the kernel and it changed to bulletproof 1.4+. Nevertheless the performance of the phone decreased at the point that he almost freezes sometimes (no restarts) and also can't acess phone storage via usb in windows. When I plug it to computer it beeps as a normal device inserted and htc one s device appears but I can't see any of the contents inside it.
After some days, I decided to install Busybox app and somehow that app makes some miracle and the phone got something better in terms of performance, but never as it was before the installation of the kernell. Even know the phone has some freezes, but Can someone help me recovering the normal phone performance?
I'm factory unlocked
