Root Planning to root 5113 / 4.2.2, Any specifics?

[Marc_G]

Hi folks,

I'm having problems with my stock 5113 Tab 2 10.1 (US), which has been unstable since the latest software installs pushed through. Reboots all the time, freezes, and drives my kid crazy. Only one of two Tab2s I have does this. Odd. Anyway, I'm thinking to install a stable version of CyanogenMod (will try a few, see which is most stable).

I guess I need to root first. I read the sticky guide, which looks like it was written long ago (4.03/4.04). Anything new I need to know, or new files I need? I see ODIN is updated to version 3 (guide refers to 1.85!).

Also, I'd like to back up the current state (stock rom, etc.) and haven't quite figured out the right way to do it. Links appreciated.

Meanwhile I'm googling the heck out of this. I'm very computer literate but never rooted / custom-ROMed an Android before.

First update.

I'm rooted.

Made sure I had latest files needed by checking here:
How to Root Galaxy Tab 2 10.1 GT-P5113 Running Android 4.2.2 JB Stock Firmware | NasirTech | #1 Samsung Firmware Destination
Those instructions got the volume up/down keys mixed up so I had some trouble getting into download mode but the more detailed version in the sticky here on Android Forums helped me get past that.

I downloaded and ran root checker and it confirmed my root.

Only heart attack is that it took a long time for Odin to report Pass, even after the tablet had rebooted and so on.

Next, attempt to install custom ROM. Should be fun...

Second update:
After doing more research I was able to get the clockworkmod ROM manager downloaded to the tablet and used it to flash the Clockworkmod recovery environment.

I could then use clockworkmod recovery to backup to external SD card. That done, again from within recovery, I installed the cyanogenmod version of 4.2.2 from a zip I downloaded from the CM website. Initially this would not boot (hung at cyanogenmod circle screen).

Solved that by going into recovery again (boot power plus volume down) and doing a FDR. Then it booted fine.

Next step is to install Google apps tonight.

Third and probably final update:

The Cyanogenmod 4.2 was fine, but I found a Kit Kat 4.4.2 ROM I liked better from OMNIROM.ORG. I'm using the 5110 version of the rom (they don't have a labeled 5113 version, but the 5110 seems to work fine).

Here's a link to the development thread for it, which includes all the links to the hosted files.

To get this going I did the following:

Used ODIN 3.0.9 to flash the TWRP recovery onto my device. The version of Clockwork mode recovery didn't support the omnirom I was trying to install. TWRP 2.7.0.1 worked fine though.

In preparation, on my PC, I made sure my external SD card for the device was clean and then I loaded the three required zip packages onto it (the Omnirom itself, the Google Apps package [minimal version], and SuperSU which manages superuser access).

With TWRP installed as the recovery, and the SD card installed, I booted to recovery and did a thorough wipe of all the caches and formatted the memory per the instructions in the thread I've linked. [This is very important; I actually forgot to do it first time around and the OS wouldn't boot. I remembered to do it and redid the process, then everything was fine.]

Then, one at a time, I flashed the OMNIROM, Gapps, and SuperSU. I then rebooted the tablet. It came up in OMNIROM and gave the usual setup screens. Time to enter my wifi password, time zone, sign in to Google account, etc...

Everything worked fine with a minor exception due to the specific build of the ROM I used (it assumes a hardware keyboard, have to turn that off with each boot). This problem has since been corrected and I might reflash with the updated version to avoid the minor annoyance.

The minimal Gapps package includes the Google Play app so I was able to download all my regular google stuff (gmail, google search, maps, etc.). I was able to download as well all the paid apps that I had from before.

Anyway, the tablet has been very stable ever since doing this and my son can play his games without constant reboots, and I can use the tablet for my stuff without fear as well.

For anyone with a Tab 2 10.1, (or other versions supported by omnirom), I recommend the Kit Kat 4.4.2 Omnirom. It is fabulous and easy to install.

Good luck to all!

Man, thank you. I've always wanted to run android kitkat on my tab 2 p5110, it's a different model but I've heard it runs well!

Next job for me is to get a new laptop!
