Vim1 will not boot into OOWOW

Hey all, I had been flashing Vim1 Khadas boards using OOWOW for ages to install Ubuntu Server onto boards but recently I have had boards that will not boot into OOWOW using the methods I had been doing.

I have flashed OOWOW to an SD card using Balena Etcher using the vim1-oowow-latest-sd.img.gz file which has been fine in the past.

For the methods to try and boot into upgrade mode to access OWOOW I have been:
Using TST, so triple-clicking the button.
Long pressing power, clicking reset, and letting go of power after a couple of seconds.
Even had a look at using the M register on the back.
But when the Khadas boots it will boot into the Android OS the Khadas shipped with.

Any thoughts or ideas on what I could be doing wrong? Cheers

A ttl adapter on the debug port will tell you what is going on. You might have to erase uboot from the => prompt and force it to boot from SD.
