I installed as usual, Odin ☺ At first I was unable to make it work, my tablet was freezing at the boot so I had to flash cf root over and over to make it work (at first I was flashing the full rom and later I found that flashing only the cf root does the trick). I believe something changed on this latest update that it's working nicely with our P905M.

So download the latest TWRP and flash it with Odin.

1. Load the image with the pda button.

2. Don't touch anything else.

3. Flash it.

You may want to have the original firmware image available in case something goes wrong, but remember, load the image with the PDA option and don't touch anything else. If you get stuck on the boot flash the original firmware or the cf-root file that can also "unbrick" your device.

Good luck ?

BTW, the latest Odin doesn't have a PDA button, I believe it is labeled PA.

[Galaxy Note Pro 12.2 Original Android Development] gorcutt:
According to this page it seems it's Exynos based.

Well, actually, looking further I have no idea. On the main text it says it's Exynos, but in the full specs it says it is a Qualcomm. So, go figure....

Why is TWRP the most difficult file to find?

1. I am eternally grateful for TWRP.

2. I've never had so much trouble finding the proper TWRP files whenever there is a post for a new version, no matter the device.

This is the Note Pro 12.2 Orig Dev forum, the title of the thread says 2.8.1.0, but that file just can't be found. The TWRP site has a few different entry points for finding a device, but none of them list 2.8.1.0 for v1awfi (if you're lucky enough to know the code name).

I guess I have 2 questions:

1. Does 2.8.1.0 exist for this device and if so, where the heck do you find it. The TWRP app throws an error saying it's confused if you pick v1awfi, if you hit the install, it says file doesn't exist, The Goo.IM app is gone and it hasn't been fully integrated into Rom Toolbox yet. Where the heck is this thing? (Please). I'm a sponsor for goo.im and have been a pro user of Rom Toolbox since day one. I pay for all my utility apps.

2. I've found this mild frustration for nearly all my devices. I'm going to donate to the cause because without TWRP we'd live in an awful world, but I can't be the only person who runs around for an hour to try to find a file announced in the title of the thread. Could putting a link in the OP to the file referenced in the OP be added?
[Galaxy Note Pro 12.2 Original Android Development] bigbiff:
I don't trust the apps anymore to work right. I advise Odin, then zip, then dd installs in that order of preference.

EFS backup missing.

As I find it a very important partition to backup I just unpacked your recovery and added the following in the twrp.fstab (green)

/boot emmc /dev/block/platform/dw_mmc.0/by-name/BOOT
/cache ext4 /dev/block/platform/dw_mmc.0/by-name/CACHE
/data ext4 /dev/block/platform/dw_mmc.0/by-name/USERDATA length=-16384
/recovery emmc /dev/block/platform/dw_mmc.0/by-name/RECOVERY
/system ext4 /dev/block/platform/dw_mmc.0/by-name/SYSTEM
/external_sd vfat /dev/block/mmcblk1p1 /dev/block/mmcblk1
/efs emmc /dev/block/platform/dw_mmc.0/by-name/EFS [COLOR=Green] flags=backup=1;display=EFS[/COLOR]
/radio emmc /dev/block/platform/dw_mmc.0/by-name/RADIO
/usbstorage vfat /dev/block/sda1 /dev/block/sda flags=display="USB Storage";storage;removable

Repacked it and now it makes a backup ot the EFS partition. I tested it and all the files are in the backup as well the permissions.

I attached it , you can install with custom recovery , now you have a backup / restore option for the EFS partition.
[Galaxy Note Pro 12.2 Original Android Development] bigbiff:
v1awifi I thought was wifi only? What is the model # of your device?
[Galaxy Note Pro 12.2 Original Android Development] civato:
A wifi only device got also a EFS partition which contains device exclusive info like "imei" "wifi mac", etc..... if this got corrupted in any way and you don't have a backup, wifi, bleutooth and other stuff won't work anymore.

My model is P900 Exynos wifi only device. The EFS partition is not only important for device with a modem for 3g or 4g.
[Galaxy Note Pro 12.2 Original Android Development] bigbiff:
Please let me know if http://techerrata.com/bigbiff/openrecovery-twrp-2.8.1.0-v1awifi.zip lets you backup EFS.

Any chance you can include modem backup?

The Note 3 version of TWRP includes modem backup. This would help for developers who include modem.bin in their installs. There have been times when I want to go back to a previous modem version and a restore is easier than flashing a modem version.

Thanks for your hard work on TWRP.
[Galaxy Note Pro 12.2 Original Android Development] arcadia2uk:
It's already up on the official TWRP site check for version 2.8.1.1. This is for the P-900 though, as I don't know what model you have.
[Galaxy Note Pro 12.2 Original Android Development] gcrutchr:
Sorry. My model SM-P901 is in my signature.
[Galaxy Note Pro 12.2 Original Android Development] arcadia2uk:
Sorry, I missed that.

Anyway, your model is the v1a3gxx in TWRP lingo, and your directory would be this one just download v.2.8.1.1, I suggest the .tar file to be flashed with Odin.
[Galaxy Note Pro 12.2 Original Android Development] gcrutchr:
Thank you.

EDIT: Although I see EFS backup, I do not see modem partition backup. Any chance this will be added?

Support for encrypted device /sdcard in the next release?

---------- Post added at 08:35 ---------- Previous post was at 07:42 ----------

Reverting to 2.8.1.1 - 2.8.3.0 can't mount "System", or backup /re-install.

TWRP restarts and locks on any attempt to access the System partition (restore process, new ROM install, etc.).

2.8.1.1 formatted System as expected and restored the backup image.
[Galaxy Note Pro 12.2 Original Android Development] bigbiff:
No logs?
[Galaxy Note Pro 12.2 Original Android Development] 00bofh:
TWRP 2.8.3.0 didn't generate any - and the "Copy Log to SD Card" option when it came back from crash didn't drop anything useful either (recovery.log == 0 bytes).

Wiping /formatting system, mounting a partition, restoring a previous backup, creating a new backup, or installing a ROM from .zip proceeded normally until they touched "system" in any way.

Brief flicker of the screen, black for a moment, then the TWRP splash to main menu startup sequence.

Wipe the Data partition again (or Dalvik Cache or Internal Storage)

The tablet shuts down. You need to press the Power button for 30 seconds to boot again.

The above behavior occurs on TWRP 2.8.3.0 not on TWRP 2.8.1.1. I' ve attached the recovery log.

Also another minor UI issue. The "Download" button on the Reboot screen is misaligned too far to the right.

Also the Power Off button on Reboot Screen does not power off but reboots in TWRP.
