You did not state which AOSP roms you tried but I can tell you I'm on Liquid's 3.2 and have not experienced any problems yet. As far as a stock rom that is rooted, you can try
this. It's a debloated and rooted stock rom from the latest RUU.
First I tried OMGB, which was flawless on my Incredible, but has several major bugs on the T-bolt.
Only one side of the headphone jack works (left side) and when I am talking on the car handsfree wired kit, the person talking sounds very high pitched and weird, but playing audio sounds fine (other than the right channel not working) which is weird.
And currently I am on Liquid 3.0, and it has a couple of bugs. ( I just downloaded it a couple of days ago, so is 3.2 brand new?)
1. When I am plugged into my car handsfree rig (which is wired) it makes a weird static noise that the person I am calling can hear but I can't. And it comes and goes. I never had that issue with my incredible or with my tbolt on the stock rom. I did have a similar issue running OMGB on my tbolt as well, though not identical.
2. Yesterday on the way home from work, I drove through several areas that have always had a strong 3G signal, but now even have a strong 4G signal. But I had no signal at all, not even 1X. I couldn't even make a call. The voice (CDMA?) signal came and went but the data never came back. So I rebooted into recovery and wiped the caches, and rebooted again. Then it seemed to work better, but still no 4G. I don't know when it happened because I'm on Wifi at work all day, so only when I was driving away and got out of the Wifi range, did it try to switch to 3G, but failed.
So, I'm getting frustrated, and ready to just say that the Thunderbolt hasn't been out as long as the Incredible, so that is why even the best ROM's still have bugs that haven't been all ironed out yet. And just go with the stock rom, until later.
Even now, I nand-restored back to OMGB and I have a 3G signal at my desk (a weak one, but that is normal).
And I backed up right before I did that, so now I restore back to Liquid and....ok, now I do have 3G again. I guess it's possible that could've been a network issue, but I drove a long way, and it didn't change at all. I had zero connectivity. I switched to airplane and back a few times, thinking that would force it to reconnect, but nope. In about 10 years as a verizon wireless customer I've never seen that before, so I'm not saying it's not the network, but I'd be surprised if it were.
And I have one more question about liquid.
I have read that the CM7 team still hasn't gotten 4G working on their ROM, nor does OMFGB. So how does Liquid have it already?
And when I'm on 4G it doesn't seem to be much faster if any than 3G.
Does Liquid 3.2 fix any of the problems I mentioned I'm having on Liquid 3.0?
Thanks for your help!
edit: And now I am connected to Wifi and it still shows the 3G icon at the top, and when I do something like refresh my facebook widget, the 3G arrows light up. Why would it be using 3G at all if I'm on Wifi? It never has in the past.
