Help?

However, you might be able to just get an older version of TWRP and just flash that over Odin.

Thanks for your reply.

In case anyone else does this to themselves (derp), I solved the problem. It was easy, actually.

I just redownloaded the zipfile for the modified TWRP, pulled the recovery.img file out of the zip, and reflashed it with Heimdall.

Problem solved.

  1. Make a nandroid of /data
  2. Back up your internal SD card to your computer
  3. Install the official TWRP recovery
  4. Reboot back into the official TWRP recovery
  5. Wipe your internal SD card
  6. Copy back the data to your internal SD card
  7. Restore your /data nandroid

So if I'm not restoring a /data nandroid, I can just flash a new rom, correct? Or does restoring the /data nandroid actually contribute to "reformatting" the partition?

I was able to do so without issue.

When I try to wipe internal sdcard, I get error, "invalid partition selection."

I flashed the newest TWRP (2.8.7) via Heimdall.

What am I missing?

Bump - any help here? Odin seems like a long roundabout waste of time.

Have you tried reformatting? I haven't actually tried to "undo" the virtual partitioning, however it's been discussed in a few of these threads and I think the consensus is to reformat everything with the unmodified TWRP. When I say reformat I mean the change file system, rather than just a standard wipe. If you haven't done that already, I'd start there.

This is an unofficial CyanogenMod 12.1 Lollipop ROM. This is currently a work-in-progress, so you can expect to run into problems while using it.

You must perform a full wipe (wipe /data) before installing this ROM for the first time. New updates can be flashed on top without wiping anything.

The first boot may take up to 10 minutes.

Working:
  • WiFi
  • GPS
  • SD card
  • Modem
  • Mobile data
  • SMS
  • Phone calls
  • Audio
  • Camera
  • Camcorder
  • NFC
  • Bluetooth
  • Sensors
  • Video playback
  • Flashlight
  • USB
  • MTP
  • VoIP
  • Anything else that isn't listed as broken

Issues:
  • SELinux is currently set to permissive
  • Device sometimes (very rarely) locks up at the boot animation

Kernel source code:
(cm-12.1 branch): https://github.com/sultanxda/sultan-kernel-celox

Google+ community

Downloads:
NOTE: You must virtually repartition your device, otherwise you cannot install this ROM! See the 3rd post for details.
ROM: https://www.androidfilehost.com/?w=f...&sort_dir=DESC
Google apps by dhacker (click on 'Download Now'): http://d-h.st/BX7Q
Kernel-only updates/kernel Aroma installer*: https://www.androidfilehost.com/?w=f...&sort_dir=DESC
TWRP recovery updates**: https://www.androidfilehost.com/?w=f...&sort_dir=DESC

*The ROM comes with my kernel built into it; however, sometimes I may release an update for only the kernel and not the entire ROM, so the newest ROM update might not come with the newest kernel. The kernel-only update package also comes with an Aroma installer that can be used to configure some kernel options (such as display undervolt).

**You must have completed the repartitioning process in order to install the TWRP recovery updates.
