ECM Locked
Attempted to flash in a new tune this morning and it completed a flash but will not start. Attempted to reflashed and get the $0537 Controller is Locked with Custom Key. That is not true at least not from me anyways. I updated recently and did not have a problem flashing 2 days ago. Now the truck is useless. Please help!Attachment 20005

Probably not much help but did you try a full flash?
-
Yes I did. Tried everything etching except disconnecting the battery. I will be trying that soon.

What happens when you check assume lock is faulty and try alt keys?
Never heard of this happening to the LML before... I think the flash touched something it wasn't suppose to. Did you update efi live since the flash you did 2 days ago?
-
It comes back as $0537 error, Locked with Custom key. Updated and have flashed once since the update. Today it wasn't successful.

I have noticed since the update it will ask to save a file that wasn't in the process of modifications. I kinda thought that was a little weird.

Rip. Go make a ticket with efi live... They'll probably be interested. Congrats on the first bricked lml that I know of. Well its not really bricked, but somehow I would imagine the memory that stores said key is corrupted. If the corruption isnt something easy like 0000 or FFFF or 8000 or 0101 or 0001 or something easy like that... I doubt you'll ever get in.

That is very strange indeed, I don't think any tuning software in the world is capable of locking the LML ECM's due to the way Bosch ECM's are designed so I don't know how that would come up.
I don't know what to suggest other than maybe unhook the battery for 30 seconds and retry. If you didn't do a full flash then there is no need to attempt to recover it via a full flash, a cal flash would be fine.
Can you please attempt a pass-though cal flash after unhooking the battery for 30 seconds and then send the trace file to support at EFILive.
Edit: I see you've posted elsewhere you sent the trace files in to support.

I did send those in. I also had Socal connect via team viewer and we went through everything together. I has a reoccurring longterm memory failure code. There is no record of the Vin etc... I just ordered one up and a new license and we can go again. I don't know how it happened. That really is my luck with breaking something or having it fail without even trying to.
