    hello, guys I have a problem, if I use your u2 files do not start the chip right away, in the sense that I have to press the trinket button or itsybyte more on and vol + button and the console starts with payload etc, instead if I put "sam-fusee-launcher-internal" enough that I press the vol + and on key and the console starts in rcm and the payload works, can the same function also be used on your u2 files? or if someone can convert that sam fuse launcher internal to even itsybyte

    Oops... Guess what. I forgot to update the packs. I updated the basic files thread with new Hekate. But forgot these. Will do these in next hour

    No you don't need to change anything. Just run hekate as your start.bin

    Ive changed the 0 folder slightly. The "s2" was hard to fit into the failure graphic. So I changed them to nx files. Same files, just different names.

    It should. Best thing to do is delete your 0 folder and start again. I`m not sure what you have changed. The version in this OP and in the basic UF2 thread are the same.

    There has been a lot of changing and suck-it-and-see to find the best way to do things.

    Hello all !

    Just one question, it's important the Optional Bleu point to not use AutoRCM ?

    Because, i use the Trinket and without this point, my switch boot an official firmware (with/without Vol+ Power) :(

    OK. Have you chosen a bootloader UF2 from the packs in the OP?

    Remember, there are 2 UF2s you need to send.

    1 is the bootloader to select your straps, the other is the chainloader.

    OK... You need one of the other files in the pack too to activate your straps on boot.

    Version 1 & version 2. Choose one.

    Once flashed, you need to resend your mode1 or mode2 file

    @mattytrog : this point, we must solder the two point or just the one on left ?
