Flex Boot Glitch Unlock: Can Kess3 or AutoTuner Read It After?

Following on from our MD1CS003 Boot Glitch video, we take the ECU we unlocked and read/wrote successfully on Flex and put it on the bench with Kess3 and AutoTuner to see if either tool can also read and write it. This answers a question we've seen come up a lot since the Boot Glitch method launched: once an ECU is unlocked using one tool, is it actually unlocked, or only unlocked for that specific tool? We show you exactly what each tool reports, whether it recognises the ECU, pulls a chip ID, and whether read and write actually complete. If you're using Flex for MD1CS003 work and wondering whether a Flex unlock carries over to other tools, this should give you a clear real world answer.
