[jonas2790]

Is rastomanchik also working on this ROM?

I think he will work on it (maybe after kitkat is totally completed)

 

[Minto107]

Nice to see that HTC One V is not dead! Great job mate!

 

[NSDCars5]

Amazing work on this! I never thought my One V would even run KitKat, honestly.

Anyone notice a speed difference with and without Gapps? The ROM seems to be excruciatingly slow if I use Gapps, but if I don't, it's as fast as CM11.

 

[sultan1419]

Can you?

Can anyone tell me whole installation process please. Do i need latest recovery? How to install latest recovery through mobile?

[hehaichi]

please respect the developer. And no ETAs.

I am in NO WAY disrespecting the developer. He/She may choose not to reply to my query.

 

[AuliaYF]

I am in NO WAY disrespecting the developer. He/She may choose not to reply to my query. I dont need a third person poking his nose.

no need to be like this, but asking for ETAs is breaking the xda rules.
