[GUIDE] Flash Official JB 4.1.2 Firmware on P6810 Wi-Fi Device

Sick and tired of Samsung ignoring the official JB 4.1.2 update for our much maligned and forgotten device?

Well, you’re in luck, this guide will effectively turn your P6800 Wi-Fi device into a P6800-GSM/3G model. We do this by changing the device partition layout and then flashing P6800 firmware with Odin.

Of course, due to hardware differences, you won’t have a working radio/modem. Also, some unneeded system apk's will need to be removed and the UI will also need some cosmetic changes etc, but it's a start.

WARNING & DISCLAIMER: I am not responsible, YOU are! You can probably forget about your warranty. This will wipe everything and increase your flash counter too !

Let me know how you go. You should be fine as long as you meet all the requirements and follow the steps.

Why do we need to flash p6800 recovery? Due to different layout partition? So if we need to go back to p6810 (through restore from backup) we need to flash p6810 recovery first?

After flash the P6800 firmware, you don't need to flash any custom recovery. It's just a recommendation and also reminder to flash stuff for P6800. You need it if you wish to flash eRobot ROM.

TO RETURN TO P6810 PARTITIONS & FIRMWARE

Follow the above steps but substitute Step #3

A - P6810_WIFI_16G.pit + bodivas P6810 JB ROM .tar file + then flash P6810 CWM/TWRP Recovery & FULL nandroid restore

To be clearer: If you need to go back,

1. Flash P6810 PIT + bodivas ROM in Odin
2. Let ROM boot
3. Flash P6810 CWM/TWRP Recovery in Odin and then FULL restore the ICS Nandroid

Don't forget to keep the Nandroid backup on your external sdcard, internal will get wiped !

Is it completely impossible to flash back to stock using Mobile odin from bodivas ROM?

I don't know, but haven't found a way with PC Odin yet. Still a few things to try later on using old ICS 4.0.4 bootloader etc.

The only successful method so far is the Nandroid way.

Update. It seems I have wifi issues with v1.6.0. I unpacked the kernel from bodivas rom, reflashed, seems OK, now. Wifi would only work if I turned it off and on again. No usb otg now:crying:

I think you're in the wrong thread.......

Anyway, I tested all OK on bodivas stock ROM. Had no issues the past day. Backup your data and save off device. Reflash his stock ROM (no multi-windows) and try again.

BTW, I have managed to revert to ICS 4.0.4 without using nandroid. :highfive:

I'll post the method here later today. I have some business today.

From now on, I'll be using eRobot, but must make a flashable script to uninstall some non-related feartures and apk's etc. I'll even attempt later on to modify some apks to get rid of some unneeded options in settings menu.

I don't use Mobile Odin, but don't think it's possible.....

Now enjoy your JB "P6800" or ICS P6810

Cheers,

Edit: Nearly forgot, thanks bodivas for suggesting Factory Reset.

After flashing JB, I don't think flashing CWM or TWRP is working properly. I get successful flash of P6800 TWRP, but fails to boot into recovery volume up + power. Flashing the P6810 TWRP recovery partly works, but does not show the internal sdcard. Maybe something to do with bootloader still showing P6810 ?

Will take a look later.

~~BUG - Can't quite get any custom recovery flashed properly on JB~~

Edit: Just flash TWRP 2.6.1.0 in Odin [PDA]. Done

In TWRP recovery:

Internal sdcard = emmc
External sdcard = sdcard

My P6810 IS NOW running eRobot ROM + SkyHigh kernel :

EDIT : STILL A FLAW IN THE "RECOVBERY PROCESS". SOME RECOVERIES STILL FAIL TO FLASH AND OTHERS DON'T MOUNT /RECOGNISE ALL PARTITONS. THE TWRP 6.1.0 DOES NOT BACK UP THE PRELOAD PARTTION, WHICH IS A REQUIREMENT TO RESTORE CORRECTLY.

furius · Nov 16, 2013

Running erobot rom and skyhigh kernel on my P6810 too!

I followed your instruction and all was fine! All is working well, I'll report more feedback in the next days ...
Thanks UpInTheAir

furius · Nov 16, 2013

One more thing: from your screen shot you are using tablet UI while erobot has phablet UI ... I tried to switch to tablet UI changing lcd density but touchwiz continues to crash ... how did you get it working?
And again ... is there the possibility to have the multi window feature as in bodivas rom?

I was running eRobot v1 , Phablet is v2.3P. I really do suggest a full wipe immediately prior to flash (if ROM doesn't automatically). I haven't flashed v2.3P yet, but have a read through the eRobot thread on the development section. Please let me know what you find out. Edit: jhust flashed it, working ok

http://erobotrom.blogspot.com/p/erobot-rom-for-g-tab-77.html?m=1

I have permission from eRobot to modify and release his ROM at XDA. I was going to do tablet UI, but now doing Phablet instead. I am working on a Aroma installer version to flash in custom recovery. As per my previous post, custom recoveries aren't working 100% with preload not being able to backup or restored. We need this for 4.1.2.

Although the guide works flawlessly, the end useability is not quite there with custom recovery not quite working as expected.

If I can't get this working easily for user simplicity, the eRobot ROM will be built/modded for P6810 partitions instead. So the only requirement will be flashing bodivas base ROM and custom P6810 recovery from daniel_hk TWRP 6.0.0.0. I have some family time today, but hopefully have something out for "P6800" partitioned or original P6810 partition device soon.

Edit: Just Flashed "version 1" of eRobot 2.3P SkyHigh Edition with new Aroma 2.70RC2 installer. Just got to config for a lot more Aroma options before first release. Flashing and testing takes time, just one little error can give a big headache ! Just look out in the development thread for a "new" ROM for the P6810 in a few days time. If a FULL wipe is done (preload, system, data, dalvik), there are no flash issues. Maybe I'll look at adding a few more system mods (time permitting) later on, wait and see.......

This appeared to work well for me. Then I got to the screen where there is the, "Reset perangkat" dialog button (and a back button on the bottom left). I've tried over and over to tap either button, but my touchscreen is apparently non-responsive (and the screen times out and goes to sleep as you're touching it - so apparently it's not detecting any input). I tried reflashing again, and there was no change. The screen orientation automatically rotates, the volume buttons work, the power button works - it's just that the touch screen is non responsive. I am going to try downloading a different 4.1.2 ROM from SamMobile (but their servers are slow so it'll be awhile).

Any other ideas?

Quite strange, I've lost count the times I've used this method and not come across this.

If you get stuck at the reset screen again, maybe you could try:

1. Disconnect USB cable
2. Enter stock recovery: factory reset (hold volume UP + power until enter recovery)
3. Reboot and wait 5-10 mins for first boot

If still not working, try flash again same full firmware package (same CSC), because it won't/shouldn't ask for the reset if already flashed (didn't ask again for me anyway)
