Odin failed to flash ,if you could or would possibly make a flashable zip you will have made my year

Thank you so much

Thank you again so much

I'm in the process of trying it right now, thank you again for taking the time to upload it. I know it was a pretty big file to begin with. I will keep you posted on any progress I make

Is your wifi not turning on and just disables itself?

I may have a fix for that. I'll upload shortly.

I had an idea that would happen.
There is a way to force flash it.

We can use Heimdall(it's like an open source command line version of Odin), which can be downloaded here:http://glassechidna.com.au/heimdall/

If you're happy to go ahead with Heimdall then download it and we'll go from there.

I'm not going to really have access to a computer for a little while. So is there any chance of making it a twrp flashable? Really I appreciate all you've done as it is and don't want to really ask for too much, but I don't really know what else I can do

I may be able to work something out to get access to a comp. I appreciate all you've done for me as it stands so worse comes to worst I'll get a cpu to use the few minutes it generally takes

Ok connect your tab via USB and ensure USB debugging is enabled.
Install EFS PRO then run the program.
Click the BACKUP tab then uncheck MD5 checksum verification
Click Device Filters and select ALL Partitions from the dropdown menu.
From the left deselect ALL partitions except APNHLOS then click BACKUP
When its finished open the EFSProBackup folder and you will see your backup.
Place the wifi fix in this folder.
Next go back to the program and click the RESTORE tab
Uncheck MD5 checksum verification
Click click refresh under Backup Archives, you should now see the wifi fix in the drop down list with a (PC) at the end
Select it and wait for it to be copied to the device then hit RESTORE

Device should then reboot and hopefully will have flashed OK.

Is this when creating the backup?

Can you extract the PIT file with EFS PRO under the Samsung tools tab?


We can still this with the DD command. Can you run the following command in a terminal on your device, either ADB or a terminal app will do. This will give me the partition layout then post it here:

For some reason this stupid board wont allow me to post the command, so Ive posted it on pastebin: pastebin.com/3ptEEDYM

To save time if the APNHLOS partition points to dev/block/mmcblk0p1  which I'm confident it does then the command below typed into a terminal emulator on the device should flash the image to the right partition. If it isnt don't use the command. 
However first you will need to extract NON-HLOS.bin from one of the files I previously sent you and place it in the root of the internal sdcard  /sdcard. 

Move the backup of NON-HLOS.bin that was made in /data/media/0 when you flashed the previous zip in TWRP to somewhere safe then place the extracted NON-HLOS.bin in /sdcard
Then run these commands exactly as they are from a terminal:


su
dd if=/sdcard/NON-HLOS.bin of=/dev/block/mmcblk0p1

I also redownloaded the odin file and it failed verifying the aboot

I dont think i have a pit file either. Ive looked high and low and dont understand where it could be

You realise they are 2 separate commands?

First - su
Then - dd if=/sdcard/NON-HLOS.bin of=/dev/block/mmcblk0p1

If it still failed it means the path is wrong.

At least you got it sorted now. My advice is to make a complete backup with TWRP once you have it up and running.
