[Galaxy Tab  Android Development] Kostiz:
Overcome to Omni - My attempt

Hey Team XDA!

I have not been on here since the days of overcome by Alterbridge86 ( a long time ago...) :p

My GT-P1000 has served us well and still going strong and managed to survive 4 kids growing up up until today when I allowed it connect to wifi and it update some of the apps and now the device starts fine all the way through to the home screen then shuts down (completely turns off) a few minutes later :crying: Since I have no idea what is causing this to shutdown I came back to XDA to find overcome is no longer in development and the safest option is to move onto OMNI.. Great! :good:

This is where my problems begin as there is no real easy process/guide for us oldies to follow since overcome had a nice PDF to follow. :eek: Here is what I think is needed and what i did in order to get the TAB back to a usable status and I am by no means an expert or know the mambo jumbo and terminology used here and there but I will give it a shot to help my fellow OC comrades move across if needed :D

First up the best option is as always to perform a restock, this means putting back a clean ROM in my case I used the 2.3.6 Gingerbread stock ROM which can be found HERE - (The reason for a clean install is to simply make sure it removes all the other crap left behind from other ROMS and it will save you a headache, so don't bother with the "dirty" approach :fingers-crossed:

Once you have this file, GB_Stock_Safe_v5.zip unpack it as it contains all the required attachments/files/apps to "restock" and while on that link/page grab the PDF file too as you will need this guide if you have not done a restock in a while, (like me) so follow it to the letter for restocking up until you get to the steps to add the Overcome_7_series_v4.1.0_wipe ROM.

(One thing to note is make sure you have the TAB's drivers installed depending on the OS you are using & working with your device as in my case Win10 - for me I to use compatibility mode to get it working including Odin)

When the TAB reboots to the step above, you should have a nice clean 2.3.6 with overcome kernel and recovery, so from here is point where you add the omni.ROM I placed all my files in the internal storage to load and removed the external SD and SIM card to avoid problems and just loaded them via recovery. So instead of adding in say the Overcome_7_series_v4.1.0_wipe ROM you replace this with say in my example I used omni-5.1.1-20151206-p1-HOMEMADE.zip once you kick this off it will take a few attempts to get it going.

From my limited knowledge the new OMNI install seems to perform partial steps of the update with the first being the actual re-partitioning hence it then exits but it looks like it failed, don't worry but read the display to get an idea of what's going on and once TWRP pops up install the omni ROM again and even a 3rd time to get it loaded in the TAB. Once it's finished it should show you something like "enjoy OMNI!" then reboot. (I did wipe cache/dalvik at the start as per the instructions via OC and at 2nd point of the install of OMNI so not sure what affect that had good or bad).

When it boots you should see the android animation pop up with OMNI, let it load as it takes a few minutes to do it's thing and start the apps. Once you are ready you can add GApps, I used the pico ones, labelled tk_gapps-modular-pico-5.1.1-20150920-signed.zip

Steps are the same

1. Download and copy file to internal oe external SD card.

2. Reboot into recovery

3. Flash the selected zips (Packages and then Add-Ons)

4. Wipe cache and dalvik

5. Reboot the device

You can find more GApps via gapps central page

One thing I didn't know is when to add in the SuperSU, so I did that before I added the GApps, so again, not sure the impact or whether this is incorrect or which order :confused:

In summary all you need to do ONLY IN FIRST INSTALL: Do a full wipe (data, system and cache), prepare re-stocking via Odin, flash GB Stock Safev5, then Overcome Kernel then flash the latest build of Omni Rom flash your ROM and then the GApps. :victory:

I've not don'e much testing but it no longer shuts down, so I am on the right track :p

I hope this helps OverCome peeps and others who are not sure on the basic steps and I would also personally like to thank all the DEVS past and present who challenge not only our devices but us as well!!

PEACE

Kosti
