[Atrix 4G Android Development] sathelate:
What do you mean by "broken" ? is power amp acting like : you' re raising the volume up, and power amp seem lost and climb up the volume and then no sound, one another press, climb up the volume (really annoying things) ???

If its the case, inside the poweramp setting itself, it's wroted on the Q&A, but press menu then : setting>audio settings>advenced tweaks>unchek direct volume control, then go back to your player, and raise your volume ! should work flawlessly (the only difference is, you need to calibrate the audio fucus change to a lower/higher setttings if you use one

Let me know :)

I'm using Neutrino since 2.5 and i can say that GT is the best for me, with set cpuy downclocked to 800MHZ max ! WHY an oc kernel and underclock ? its beacause on faux kernel,(gt version) even on 800Mhz, it feels like at 1100 O_O battery life is really great ! i mean REALLY great if you stay downclocked, and you can have the power when you want it (keep in mind the cpu temperature ! ALWAYS !! not the battery ;) )

And, the good side of being on 800, is, let's be honest, im watching porn stream, and lots game reviews videos and everybody knows that video streaming for more than ten minutes get the cpu at very high temperature !

The game, i'm alright in most game at 800Mhz no lag, some may require a lil boost to 1000 !

the other side of the medal now : if you dont use profile within setcpu app, or any other good cpu management, your phone will get very hot at 1300 (GT version @ max speed) if you use your phone a lot !

Also, if you are an heavy user (by heavy i mean, like between 3 and 4hours of talk on 3g/H+, 1 hour browing web, + 15 minutes screen always on to do your app update during the day cause you cant wait to be home to see the new improvment of , lets say, your launcher (yeah, its my case -_-) and a coupe of txt msg, then the good side is, you can switch down furthermore up to 456Mhz knowing that your not in a hurry during the update process, or during the call, knowing that you got your phone in your pocket talking with the bluetooth.

Now, if you dont use your phone a lot, its an another things !

I would recommand the GT version if your a lil experienced with knowing how to listen to your phone temperature... otherwise, try the EE kernel wich have a very amazing battery life if most of the time, yuour phone just need to be in deep sleep inside of your pocket during the day !

Faux for me, go to deep sleep after like 15/45 seconds from i witch the screen off ! and wake to do the syncing things like once a 40 minutes, the EE, i dont know, but its able to do the sync, and god damn, im looking at the cpuspy, and i can tell you that it wakes up like once by 2 hours for like 10 seconds ! sooo, very good battery life here, but for some reason, when bluetooth chip is on, the phone wont go to deepsleep, and i got like 7hours of battery that way !

And for the GT+, you got to be experimented of you want my advice, at 1445Mhz, the cpu get HOT really quick ! and its dangerous to the lifetime of the core itself ! byut if you want that extra lil power, and you know what youre doing, then, i can tell that neutrino is the mother****ing fastest rom ever on the atrix with faux kernel ! if you want something even better, you got to switch to clemsym 1.6 Ghz !

so that said, with this HUGE ROMAN (lol XD sorry), i would suggest the GT underclock if youre a kind of heavy user, otherwise, start with the ee and then, switch later if it is not right for you by switching the kernel !

Hope that helped in your choice

your'e coming from wich rom ?

did you've factored/reseted your phone AFTER the flash ?

did you tried just reflashing over it again ??

If yeah , no, yeah to those questions, then

did you tried using fastboot clean install ?!

did you fastboot erase all ?

let me know, i wanna help you :P i know how it can be awkward to have a beautifull phone that refuse to boot :P X_X hehe
