@luksus after reflashing the boot.img it has indeed booted into ubports!
I am up and running, thank you so much for your help.

@luksus So the good news is I've successfully loaded the stock ROW and booted the tab to it, enabled developer options, OEM unlock. Amazing!

The bad news is I've subsequently followed the Fastboot instructions and all looks good. The only error I get is......

$ fastboot format:ext4 userdata
/usr/lib/android-sdk/platform-tools/mke2fs failed with status 1
fastboot: error: Cannot generate image for userdata

And subsequently will not boot.
But definitely getting closer!

@luksus
Tried a couple of things, got the same error using the compiled qdl utility.
So I thought I'd try a different machine entirely. I have a spare Pi hanging around, gave it a fresh install and installed qdl and curiously got the exact same error.

At least I'm consistent!

@luksus Hi.
Yes, I did through snap.
I did get the Tab into edl mode, but connected or otherwise I get the same error.
Is there a step by step (idiots) guide to installing and using? Sure I've miss-stepped somewhere.

@luksus Thanks for responding.

I've installed the qdl utility.
Tablet is a 3GB RAM - 32GB ROM version.
Pretty sure I'm not doing the qdl bit right. I've downloaded and extracted the ROW.
Installed qdl and run 'qdl prog_emmc_firehose_8953_ddr.mbn rawprogram_unsparse_upgrade.xml patch0.xml' from the top level folder of the ROW.

I get the error.
Waiting for EDL device
*** buffer overflow detected ***: terminated
Aborted (core dumped)

Even before I've tried to connect the Tablet. I've read all I can online about installing and using qdl. I'm running Ubuntu.

Hello.
I've got a X605L with 9, I tried the ubports installer, that failed.
Managed to figure out manually installing which seemed to work, but won't boot.
Manually installing I get a error at format:ext4 userdata
Everything else seems okay.

Then I tried flashing the ROW but when I run the qdl command I get
Waiting for EDL device
*** buffer overflow detected ***: terminated
Aborted (core dumped)

At which point I'm a bit lost. A little help?
Thank you.
Lee.
