Crap, I feel for you. :(
A kludge is a workaround or quick-and-dirty solution that is clumsy, inelegant, inefficient, difficult to extend and hard to maintain.

Don't give up!
Choose lower temperature next time - 320-330° should be really enough...

So, removed most of the parts of my failed TF534 board and soldered them on a new board. Went allright, only the large CPLD did not come off properly :(, had to order a new one + passives, resistors, etc.

You need a preheater to remove parts from a 4-layer board, because inner layers obsorb heat, increase temperature will destroy cpld..
A cheap 17€ smartphone display separator will do the job

I am getting back in this project, I've put it on hold for a while, but with new PCB's and some new components I will build a new one. I will use the 68030/68882 combo from my TF530. This time it will result in a working TF534.
