hello, I was finally able to boot the chip, check the soldering and that's it, but now I wanted to test OFW, check that the connection between the points and the pico fly have 47ohm resistance. I don't know what else I could check pkg1 decryption failed bek is missing

help i'm really desperate

Try this "copy" both firmware & Unlock UF2 files at once. You must copy one file, reconnect rp2040, then flash another file.

After using the new firmware you released, it works fine

Didn't the Kioxia work fine right of the bat with fw 2.5?

Hello, i've try the installation on OLED, it went fine (it's able to start Hekate) but i can't create the EMUMMC, it says: BIS keys validation failed! .. any tips ?

if i boot OFW works perfectly

No matter, i fix it, just change the SDCard and everything went perfect!

Before updating this Toshiba-specific firmware has been a blue light blinking and not working.

You need to run the unlock.bin but backup boot0 first

huh... maybe Kioxia are also annoying little buggers. Oh well, thankfully it solved with the pre-2.6 patch then.

I love the same thing also happened to me with Toshiba nand I installed the rp2040 resistors with the unlocking and it gave me that same error without counting that it does not let you extract the keys and when it happened to the original console it gave this error

Let me know if you figure it out. I'm trying to rebuild my boot0/1 and nand once I have time away from work

Hello, thanks for answering, I did what they told me but it didn't work, it doesn't enter OFW, it doesn't let me dump the profinfo with lockpick either, although I was able to make a backup of the nand but it's probably also damaged, I don't know what else to do, the Console was working perfectly before installing the chip, I probably damaged the OFW, I don't know how to recover it, I'm going to cry

Copy boot0 and boot1 into the restore folder then restore it in hekate. I’ve done it and it worked with the same issue

Are we shit out of luck if the backup was made after the unlock was done?

Kioxia is a rebranded Toshiba.

Backup needs to be done first as the 2.5 corrupts the boot 0 when unlock is used. Unlock should technically be done via usb recommended. Software is last resort with a backup of Boot0

Ah okey, that explains it

Hello! Don't tell me when the new firmware version 2.6 will be released?

Hopefully soon since this dang encryption....
Can't rush perfection though

BTW does anyone know a way to clear the rp2040 entirely including the persistent unlock? I read what people were saying about corrupting boot0 after unlock and didn't want to poison my backups. Though I've already flashed the 2.5+unlock and will eventually flash 2.6 in the future.

Can't post links yet, search google for "factory reset kb2040"
The nuke UF2 should erase the whole chip but I don't know if this reverts the unlock.
