Been using 5.2 since released and its kinda stable for me. No freeze, random boots etc. Signal is very good on my gsm razr, data connection is good. Im on slim kernel. I can say its stable as stock...hehe:D:D:D:D

Its just a suggestion, try to check your ss, is it the right one for xt912 or 910. And try redownload the sk 5.2. Hope it helps.

Hello me!! Its me again!!

i just used Razr Utility to go back to stock and going to try everything one more time and honestly it would be fine on 4.1.2 but i just cant settle ;)

thanks for your advice and noted

Been on 5.0 with stock Kernel for 4 days straight without the need to reboot. Running solid as a rock great job @alteredlikeness. Battery life is decent on my XT912 Maxx, could be alittle better but I'm pretty happy as it is.

Again, I can't thank all the devs enough on helping keep this device alive. Having an iPhone before this and having it stolen prompted me to try an android powered device. The Razr was already somewhat of an older phone but I got it anyway and I learned what a cool environment the android community was. I love flashing ROMS and checking out all the features each one presents, as well as trying to figure out the problems with some of them. I'll stick around for a while before I even think about getting a new phone. Thanks again to all the devs who work so hard to keep our ancient device alive. We may complain a lot but in the end I think we really all enjoy working with you and sharing our opinions. Keep up the good work!

I give it an 8/10 as far as stability goes. Only issues I have is sometimes data goes off. Might be the rom, might not be, but I notice it. Usually a toggle or reboot fixes so it's no biggie.

Battery life is pretty good for me. A couple days on a charge. I forget to charge it at night and I still wake up with 40% or higher. Really good.

Haven't tried the latest nightly yet. Maybe this weekend.

hi guys, how can i overclock xt910 with this slimkat rom? anyone hv succeeded overclocking before on this device with this rom?

You would have to flash the JBX Kernel for overclocking. Stock will not allow overclocking. On KitKat ROM's, I don't see much need for overclocking anymore. They are very fast and stable without it.

GSM on XT912

Is anyone using GSM on an XT912?
I have slimkat installed but i am facing signal loss quite frequently. Even normally signal strength seems less. Is there any solution maybe?
Rest JBX+Slim is the most stable and best combo :D

Using Slim 5.2 with GSM and no problems here. Just bad data connection thanks to awful Argentinian providers.

So as I posted in the LS forum, I'm traveling through Europe and lost my Gps. Flashed SK, and still no luck. However, works fine on stock rom.

Anybody have any ideas on What's happening? I can't use data or my phone, it's sitting in airplane mode... Until I return back to the states

    Build 6.4 on AFH

    Anyone interested in taking over building Slim for 5 devices? :) I will be ending my support for the omap4's soon..

    Sent from my HTC One_M8
    ... Additionally to my prior post: I'd build it for three devices..
    Updated to Final Release 2.2 - this is the last of the code changes from the SlimRoms team for 4.3.1 builds..
    Only on AFH for now..
    Slimkat beta 2.1 uploaded to goo.im... Graphical glitches/artifacts should be gone for real now.

    Sent from my MB865 using XDA Premium 4 mobile app
    New SlimKat pre-alpha test builds uploaded for spyder and umts_spyder. (All of my 4.4 test builds will be uploaded here)
    Grab the proper 4.4 Gapps, install on a non-main system with BMM or SS, and let me know how it goes...

    Thanks to dhacker29 and stargo for bringing up the moto omap4's..
