I've got a to be released workaround to make TNOC work with 3.6+, under the condition you're using a boot manager
(Nlaunchy/NlaunchX or ControlX)

I'll try on HW<J as soon as possible - so not this week.

I'm in Germany, in Baden-Württemberg, one of the two Länder who are forbidding graphing calculators for the Abitur exam.
So, not the best context to find/borrow a HW<J. :P

I've been making some interesting boot1 patches.

01858 write ea00000d - autoboot boot2 even if running from ram

194e4 write 00000000 - nop out find matching prod field check

193f4 write 00000000 - skip signature validation splash data
195b8 write ea00000d - skip signature validation boot2

018a0 write ea000007 - never autoboot diags
017a4 write ea000004 - never load diags even if key pressed
017c4 write ea000010 - never download diags

// to do: load manuf from different place: around 19300

01cc8 write E3A03411 - load r4 to a boot2 patcher that loader will copy to 11000000
01ccc write E12FFF34 - blx r4 (after jump, r3 will be the base address of boot2/boot1.5/whatever)
