I ran PhamQuangs Rom for a couple of days when It was first released on pdaviet forum the 21st. Very fast and stable ROM. More responsive than most ROMs. When you don't get a signal after you first flash the ROM, it is because You have to set your GSM band to "auto" manually.
The only problem I ran into, it was totally my fault, was that I let my battery go below 40% and it became un- responsive.. You also have that Blue OEM coloring bleed thru.
