Hacking WIP [Trinket] [Rebug] [Others] SWITCHBOOT_UF2 / FUSEE_UF2 modchip software

[mattytrog]

Minor update to 0.9.3

Nothing much to report. See post 2. No real reason to change. Need ideas what to implement next

Hi mattytrog and first of all thank you very much for your great work.
I just received my trinket and I would like to use 1 of your 2 "new universal" methods but I want to be sure that I will not burn fuses (I'm currently on 4.1.0 OFW and I want to upgrade to 6.2.0 without burning efuses).
What is the best choice for me? Joycon only or Both Straps? AutoRCM to be sure I will not boot on OFW?
Thanking you in advance.

I would choose both straps so it will always boot in cfw. Ofw boot if you press power+reset

 

[DniiU974]

Thanks for your advice

try and works =)

Gulp... Another "Too complicated" vote

 

[snam11]

I'm pretty sure they're just trolling, or maybe talking about the soldering part...
Pressing reset twice and drag/drop a file can't be too complicated

Just wanted to say thanks! Going to update my chip tonight.

Added a SWITCHBOOT feature list to OP to highlight to people that this bootloader is (possibly) the only way of saving fuses from a stock Nintendo FW update on a stock NAND Emmc (if using both straps)

i installed Trinket M0 internally with AutoRCM. I can boot Hetkate, yet when I try to boot SX OS 2.5.1 to boot (6.2) with Emunand, it just auto shutdown after SX splash screen. Nothing happen.

Strange...

Something has got to be amiss with your emunand. Just tested here on bench unit. All is good.

(0.9.3 simple-UF2, 6.2 firmware, sxos 2.5.1)

if i send payload from android phone, it works fine.

OK... Ill run a different test. Standby.

No issues here. Some questions...

How have you got your chip installed?
Has it ever worked?
What version UF2 are you running?

 

[khpda]

I installed internally with 4 wire. This is my 2nd device. My first device working fine with old UF2 file, so sad that my device was lost. So i buy new device, which use same installation method.

--------------------- MERGED ---------------------------

i use ur latest UF2 (0.93 ?)

 

[mattytrog]

Check your solder points. Poor GND connection could be causing the crash

I am able to boot SX without Emunand. But not able to boot emunand.

redownload sxloader (payload.bin) place on sd and try.

 

[khpda]

already tried, not help.

--------------------- MERGED ---------------------------

i forget to mention that, i am using SD file emunand (not partition).

Wait... you can block original fw from destroying fuses?
