HELP! Samsung SIII LTE - unstable issues no matter what kernel or ROM
First time poster on here and after some BIG help... any will be useful and i thank you in advance for taking the time...
Ok without writing a novel i will give as much information as i can without beating around the bush. Then followed by details on the phone.
So no matter what kernel or ROM & apps (or no apps) i put on this phone it is always unstable and reboots itself. Some ROMS doesn't even load.
The phone has been rooted correctly 'used the samsung root tool kit' with the correct one for the phone Australia i9305 LTE version.
I used to have rXTREME 7 which was OK - it rebooted maybe 3-5 times a day if i was frequently using it, but annoying.
I tried the rXTREME12.1 installed fine, the phone was restored to default, Xache & Davik Cache where all cleared and installed rom on fresh system however it would just hang on the Samsung logo... and do nothing.. i have also tried the CyanogenMod and Paranoidandroid 3.97 halo ROM's and they wouldn't load....
Currently i have Ripper Rom and it works however whenever i try and do ANYTHING it reboots itself... i will be lucky to get a good 2mins of it working correclty without it having to reboot... So far this morning it has rebooted about 31 times (no joke i have been counting) just trying to access my email... Not matter what i do, replaying to MSG's trying to answer the phone (swipe just doesn't work) or it will just reboot itself...
In saying this i have also tried to unroot the phone and installed the standard OPTUS rom and it was also so unstable it would do the same thing, however would wipe any information i had put on the phone... apps, data, contacts...
