my zte racer is gen1
i've installed 1.7gen1, but since it was impossible to work with due to many ghost keys appearing on a single touch, and was impossible to deal with.
i then flashed the 1.5-alpha2 kernel right after, and the 1.7with 1.5alpha2kernel touchscreen worked acceptably(although still with some flaws and ghost keys). from what i can tell, these keys are ghost, but the most occasional ones , when texting, come from letters on the left side of the keyboard(say you are hitting the letter O and the letter Q or W appears as well....... or pressing L gives A or S)
at least it works ok
another thing is i am trying to install busybox (from installer or normal from google apps) but it just simply cannot even having given root permission. (i was trying to install that v6 supercharger from xda-dev)
anyway the only major flaw is really the touchscreen, as far as i can tell from the rest works fine, not much to fuss about.
installing 1.6gen2 and then 1.5alpha2 works too, but i think there are flaws like not locking the phone properly or putting it on airmode it doesnt allow me to put airmode back off withouth rebooting.
also to mention that i have clockworkmod ver 3.something installed. ver 5 doesnt work for me, and a ver4 version does work, but even though i can interact, i coudlnt select anything with it(but i am not 100% sure because when i had it installed, it was my 1st time working with cwm :-) )
i am sure about ver 5 not beeing able to work with my gen1.
as for wifi, i think wifi problems occur in every rom. if you cannot authenticate, make sure you have the right passwod and network.
If you do, then try hitting Menu->advanced on wifi settings, and define a static IP address with gateway/mask/dns.
Also on wifi settings configure so it stays enabled all the time,, and not disconnect when the phone goes off.
if it still doesnt work, try rebooting your phone and the router too perhaps.
Reading back, i was intrigued about Mizahnyx comment:
" Anyone knows where is the part of the kernel that deals with the touchscreen tweaks? I remember there is another source code for ZTE kernel that I compiled, and when I flashed it, the touchscreen was working superbly (But neither 3D accel nor the accelerometer were working). "
I am not into rom development, but perhaps it could help regarding the touchscreen? Its really what is lacking in the rom, in my view.
Another thing i notice, but it's not exactly a request, more like a note.. (again as i said the touchscreen is the root of all evil, the rest is just fine), it would be nice to have the clock and weather(mainly the weather because u can see the clock on upper right corner) on the main screen. I knowyou can see the weather on the clock menu, but its just a suggestion, that i know that not everyone will like it.(or at least have a configuration to be able to do that). The google search isnt really appealing to me because i usually open the browser anyway
