I got it from @Fiddy almost for free. I traded some MF but IMO it wasn’t worth it… For him.
@Fiddy hey brother, if you ever want it back it’s all yours. For reals. It could be years from now and if we are still in touch I will send it your way my friend.
I just repaired 5 of those mods… not working, main issues are: batteries gone and the two negatives, probably the soldering machine had problems on the top right handside of the board, where the battery negative is, soldered on just one side… I soldered on both sides and resurrected.
The other negative, towards the 510 connector also had problems (always top right) with cold soldering or double tin, prob machine just jumped the battery negative and double soldered the connector negative… look at the picture with the battery negative already repaired, but you can see that it wasn’t at first.
