Hello, sorry for delay
3.3v regulator survived (suppriaingly)
With wifi module desoldered nothing was getting hot.
uC replaced, programming using fallback procedure #3 bossa went flawlessly.
I disabled wifi section in coning file (not sure if this was necessary) and board works with uart only.
Warting for new wifi module. I will take opportunity to upgrade to esp-07s.
I will post updates.
