Hacking Question Did I fry my switch? (Please help)

[Deleted member 514554]

EDIT: SOLVED! It Just started working again after leaving it rest for the night, not plugged in and doing nothing else.

I'm copying the message from a comment I made on the modchip guide thread in the hope it gets more visibility this way (I'm not trying to spam, I'm just desperate).
Guys, I think I messed up...
I was trying to install the RCMx86, everything went smoothly (or so I think), but now the Switch won't turn on at all, no icon, no charging, nothing...
One thing that happened is that initially I inverted the D- and D+ wires (connected D- from the switch to D+ on the chip) and Vol+ and Joycon strap (Vol+ to joycon and joycon to vol+); I know, it was a really stupid mistake, I confused the wire colors.
Anyway, after that, I rewired the chip correctly, tried to power but still nothing, so I completely removed the chip and the wires, reassembled the Switch, but it's still dead.
This is the wiring I made: (I attached 3v to the NAND contact, the one under the small detachable board)

Also, I know that to check if a chip is bad, it's useful to check if there are capacitors shorted to ground, and I've found something but I don't know if what I've found should be shorted to ground and I don't know if those are all capacitors in the first place. (With shorted to ground I mean that both sides shows continuity to gnd)
Anyway, these are the "shorted capacitors":
Front:

Back:

I noticed the few in back, those in the center, are right behind what I think is the main processor, and are all connected to the same trace.
PLEASE please tell me that I didn't completely fry this switch and I can recover it. I'm desperate right now. Thanks to everyone willing to help a poor soul.

The caps in your pic should only have continuity to ground on one side. You definitely blew something connected to the data lines by not connecting the right wires to the correct location. The caps them selves are more than likely ok. The faulty chip(s) can be replaced by someone that knows what they are doing (not for the novice)! If the Tegra is shorted then there isn’t much you can do to save your switch. @mattytrog might be able to guide you in the right direction.

Also, check the board well to make sure you don’t have any solder bridges. If you can’t tell if you have any solder bridges, post some detailed pics of your board and also closeups of where all your solder connections were.

best of luck

When i installed my itsybitsy i noticed if my 3v under nand wasnt properly connected then i would get a black screen with no signs of life. Fixing/removing that wire and it would fire up again. Its real easy to bridge that connection with solder. Try removing cleaning that first and see if it powers up.


Edit. Detailed Pics of your board including all points will help

GUYS IT FREAKING TURNED BACK ON. I don't know how that's even possible. I just left it overnight without doing anything and yesterday evening it was turning on at all. What could have been the problem? It was NOT charging during the night, and the battery was also fully charged before the f*** up.
I think maybe it was wet or something? I just used flux and isopropyl alcohol, but I think those aren't conductive, right?

As long as you didn't put it in a pan with oil and seasoning of your choice, your Switch shouldn't be fried.

There's no way to delete joke posts, is there...? Darn.

The Nintendo Switch sometimes can SEEM to be in a non working state.

If it does not work; ALWAYS: 12 second reboot, 30 second reboot.
If that does nothing. Leave it in the dock charging for a night.
If that does nothing. Leave it connected to a powerbank for 4+ hours.
Then redo the 12 sec reboot, if nothing go for 30 sec reboot.
If it is not on the, make sure it didn't auto go into rcm.

A lot of people have claimed their Switch was dead ... and in some cases sure.
But a lot are just certain states really.

PS above is just a quick setup, there might be more things to check really.

For example see how well this went;

Instructions unclear, fried Switch in pan.

Great advice, thank you!

Did you unplug battery while soldering? and can you take picture of it current state?

Yep, I unplugged the battery. Anyway the issue went away by itself doing absolutely nothing, the switch just started working again, I wrote it in a previous comment. Edited the first message to make it clear

Double check your wiring then, even if the unit is shorted, like ground not being wired it wont turn on with the modchip.
