Another update, but now quite positive.
After reflashing Slimrom and tytung's one over n over, i tried to flash tytung's 4.2.2, well, it succeeded.
Now i have 1,2gb of internal free memory, and it all seem to work flawlessly.
No idea why previous 2 roms didnt work 100%'ly :/
I think i won't do anything now, i am happy to have 4.2.2 features now, after 1 years of being stuck with 4.1.2
Anyways, big thanks for you Robbie. You are my life-saver once again!!!
Have a good night y'all, yawn
Rom runs smoothly, i have 1,2Gb of internal memory, but my Google Play tells me "No connection. Retry" everytime i open it
Which means i canno't update/download anything.
Tried clearing cache,data,force stop,reboots, still no profits >.< im not into factory reset again though..
_____ EDIT _____
After wake up, around 1 hour of previous usage, i had black screen... rebooted -> Setup Wizard (although no errors or fCloses, only again no internal memory
