Slate 7 Plus 4200 owners, I have a version of this ROM for you guys as well. You can find it here
This is JB-SlateROM, a customized and debloated ROM for the HP Slate 7! This was designed for the 2800 but might work on the 4600 as I haven't tested since I don't have a Slate 7.
EDIT: Confirmed working on the 2800!
EDIT: NOT working of the 4600/4601. I'll recook the ROM for you guys when time permits.
Before you can install this ROM you need CWM on your device. Go here
to get a build of ClockWorkMod v184.108.40.206.
If the bloatware is still there, go to Settings, then Apps. Find the app and hit Disable Updates. That will delete the bloatware permanently. If it's still there after that I did not remove it. Tell me what you want removed in that case.
Original launcher has been hidden (saved as an .apk-hide file) in favor of Apex Launcher.
ES File Explorer added.
GravityBox Xposed module added.
App Settings Xposed module added.
Quick Boot added.
Xposed Installer added. (Not activated by default!
Go into the installer, hit Framework, then hit Install/Update, then hit Soft Reboot or Reboot!)
