Dna200 doesn't work

[Loshan]

Hello, 

Yesterday I decided to reassemble my lost vape triade mod, I resoldered all battery wires and checked - everything was working fine, but after soldering the 510 connector - Dna won't start. If you press and hold the fire button it boots up (battery icon shows empty battery), but as soon as you release it, dna dies. Checked the fuse and it is fine, tried to short it - no luck. Maybe I overheated the chip, when soldering the 510 wires to the board?

Forgot to mention, there is one damaged part on the microcontroller (near the ribbon cable)

I'm honestly surprised you managed to get to the board without destroying the battery sled
