The battery came loose while re-flashing one of the GT-S5830 phones.
So now I have 4 fully working (three GT-S5830i and one GT-S5830), one GT-S5830i in need of SIM card surgery and one GT-S5830 that is a glass brick. No amount of multi-butten-finger-ger-poking and cursing elicits any response from the copse, so Mr Google and I think I've successfully buggered the boot loader. Time to solder on some wires and attach an STM32F013 Black Magic Probe perhaps.
I guess I could take the easy route and pop down to my local high street fone freaking emporium, to see if they can Riff box the thing back to life, but a combination of curiosity, parsimony and a slightly bruised ego suggests an alternative course of action might be more fun. I should be able to get the zombie phone to do my bidding by soldering on a few wires and shouting at it in fluent JTAG. All I need now is the spare time to play with it, and a short length of ribbon cable. The JTAG connector is easily accessible as you can see in the image below, by moving the sticker in the battery compartment.
Google even reveals the pinout.
- 1. GND (assume pin 1 is the pad at the top in my image, that is obviously connected to the ground plane).
7. NC. ?
9. NC. ?
Time will tell if I ever get round to attempting this of course of action of course. I'm sure there are more important things I should be getting on with
