[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 !



PRE-FLASH REQUIREMENTS

1. Internal sdcard contents backed up off device
2. Any apps & data (is you wish) backed up off device



DOWNLOAD REQUIREMENTS

1. P6810 Wi-Fi model with a FULL battery
2. Windows PC
3. P6800_3G_16G.pit
4. Download P6800 JB 4.1.2 DXMD3 firmware from:
a) Samsung-updates.com
b) sammobile.com
5. Odin 3.07
6. Samsung drivers



METHOD

1. Extract P6800_3G_16G.pit & P6800 firmware so you just have .pit & .tar files
2. Drivers
a) Uninstall or disable KIES
b) Install Samsung drivers & reboot PC
3. Run Odin 3.07 & install
[PIT] = P6800_3G_16G.pit
[PDA] = P6800 official JB 4.1.2 firmware .tar file
4. Download Mode
a) Power off device
b) Hold volume down + Power
c) Release buttons at Warning Menu
d) Volume up to continue
5. Connect device to PC via USB cable
6. ID:COM should change colour in Odin 3.07



7. Click [START] and watch the magic



8. If you get a screen message with button [Reset perangkat] (Reset device), just tap it





NEW PARTITION LAYOUT




FURTHER RECOMMENDATIONS
*. Flash TWRP 2.6.1 in Odin [PDA]
*. Flash P6800 JB 4.1.2 SkyHigh kernel

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 !

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
