UberCM12.1 ROM for OnePlus One! - Page 2

Download UberCM12.1 ROM for OnePlus One

Download Android 5.1 Gapps (DO NOT USE OLDER GAPPS, YOU WILL FC!)

Installation is easy, just as usual.  Follow my universal TWRP install guide. Reboot into TWRP recovery, format /system, /data, /cache, /dalvik-cache, install the firmware upgrade zip file, install the ROM, install the Gapps, then reboot. That’s it!

If you are getting errors and never installed Lollipop ROM before, you may need to flash Lollipop firmware update, download Lollipop firmware update and install with TWRP recovery before installing ROM.
You must have a rooted OnePlus One of course, you can follow my OnePlus One root guide to root.

For root, you MUST enable root for apps and adb, see How to Enable Root on CM12.1!

    I installed this ROM (5/06 version) – did full CLEAN install. It worked at first, but, once I changed DPI to 400 I got dreaded BLACK SCREEN problem. Status Bar works, buttons light up, and I hear sounds, but screen stays black (some popup dialogs still work, like if you hold the power button down I can still select Reboot etc…).

    I had this on one other 5.1.1 ROM. So, I had to revert back to my backup (which is the latest official cm 12s).

    Hi! This will not install on TWRP. Says something about zip file verification in red. Then the word in red says “failed” …….is there anything to fix this? I have over five roms backed up and never had any issues installing them

    Also, you mention above to “install the firmware upgrade zip file”………where, and what is that??? Lol
