What custom ROMs are you using? Any problems? Any recommendations?
I just upgraded from the Evo Shift to the HTC One. I used to run AOKP on my Shift [been about 4-5 years now].
Here is what I gather for the HTC One, m7spr:
Cyanogenmod - http://wiki.cyanogenmod.org/w/M7spr_Info
As of 2013.Aug, there is still no stable version [not even a RC exists].
It is still in development [nightly]. I didnt use this directly, but I used derivatives of it, so correct me if I am wrong.
I found the GPS is completely useless in this at the moment. If you use maps, you will see the GPS update like once every 10 seconds, so it is impossible to use even for walking directions.
AOKP [Android Open Kang Project] - http://aokp.co/devices/m7spr
Running Android 4.2.2, AOKP is derived from Cyanogenmod, so it is missing GPS support as well.
I recommend the version Milestone 2, if you don't want to take a chance with nightly.
I did notice that the signal gets lost every so often, so I have to go into mobile settings & re-choose the network mode.
It does not come with Google apps [Gapps] pre-installed since those are proprietary software, so you are required to download that separately. See below for links.
My favorite ROM [likely because I been with it so long], but I had to change to a different ROM for stability.
Vanilla RootBox - http://forum.xda-developers.com/showthread.php?t=2299144
Running Android 4.2.2, RootBox is derived from Cyanogenmod, so it is missing GPS support as well.
It also derives from many other sources like AOKP, so you may be familiar with it if you're switching from another ROM.
Out of the box, the mobile works without me having to fiddle around with the settings.
This does not come with Gapps as well, so see below.
Another ROM I like & use.
Stock Rooted - http://forum.xda-developers.com/showthread.php?t=2250904
Running Android 4.1.2, this is the stock ROM, in case you just want to go back.
According to the instructions, "You MUST relock your bootloader prior to using this RUU". Make sure you keep this in mind if you return to stock.
Eww, stock....I had issues with the custom ROMs, so I went back to a rooted stock [odexed]. 1st thing I did was delete everything app with the word "HTC" or "Htc" attached to it; I cleared out 316MB of mostly useless bloat. :P
That ended up deleting Gallery so I couldn't set my wallpaper, so instead of restoring the apps, I just downloaded the app Gallery ICS from:
Gapps, for ROMs without it:
It is important you get the right version of Gapps, or the apps wont work. You should re-install your ROM if you choose the wrong one.
Don't install this if your ROM already comes with Google apps. How can you tell?
