Hacking [RCM Payload] Hekate - CTCaer mod

[wicksand420]

Oh my ... and that's known to be fixed in 3.1?

yes, sorry for the delayed answer, I was busy.

 

[Drakia]

That's the kerel patch for fs.mitm (which is the true name of it).
And yes it should be.

Just a heads up, my understanding is that fs.mitm is not compatible with anything under 4.x, even though there are kernel patches applied for it. Something about differences between earlier and later firmware versions that aren't handled in the fs.mitm module itself.
Wish I had a source, but I read about it a while back, not exactly sure where.

switch firmware 2.3.0

rawnand.bin

v3.0 --------> Failed to read 8192 blocks <@LBA XXXXXXX from sd card! Verification failed.. (time taken 71 minutes)

v3.1 --------> Finished and verified! (time taken 112 minutes)

thank you CTCaer!

Almost 2 hours? Oh my god. Did you have it plugged in.

my sd card is old. (64gb adata)

i did not have my nintendo switch plugged in, the battery meter went from 95% down to %65.

Oh, well that's good to know. Thought it'd drain more. Hm.

 

[ressit]

i can use it with SD file v5 ???

 

[hellogbatemp]

what does means the error "SD card and data <ELBA 00002000> do not match"
after a backup of the nand ?

it works now with 3.1 (91 min)
thanks!

 

[Bakugo]

Is the verification process on 3.1 supposed to take so long? It took less than an hour to make the actual backup but over 2 hours to verify it.

 

[Vroksjab]

• Fix the verification code at last!
  Another side-effect of using a 32bit ms timer (from the μs original one). Plus the additional fixes to variables that could not fit in u32 storage, makes the fix completely. Thanks to all the testers that helped to tackle these dreaded bugs.
  Better redo that backup!

@CTCaer - I managed to backup my NAND without hickups or errors using 3.0 and the checksums for the files are identical. Is there something in v3.1 that has changed dumpwise or can I trust that the backups I have are properly dumped and that only the verification code is fixed (which of I had no problem with and seeing the dumps are identical)?

...or could the dumps simply not match the NAND as the verification was wonky?

@CTCaer just reacting to the Hekate desc. She is an underworld goddess, ruler of the ghosts, magic, necromancy etc. Governor of the Tartarus/Hell. So she is everything just not a protective and a blessing goddess i think based on this.

Anyway i know not you the one who made up this name.

Well, if the problem is fs.kip, maybe using fs 5.x on a <4.X can make it work.
I don't know how compatible are the internal APIs but it could worth a try.

Yeah. Only the hash process takes 45minutes. Also the maximum rate that eMMC and SD can have is low because the RAM is not initialized and BPMP is crap.
If I remember the hard cap is around 25MB/s or so.
EDIT:
If you disable verification and try to make a backup you'll understand that it takes more than the actual dumping.

Not everyone was unlucky to reach that bug. And single file backup was working in v3.0 but it could fail because of the timing thing.

I think you read a description for another goddess, or you haven't read the whole article.
(Yeah she was sometimes associated with some of these but mostly on the christian days. But in ancient and christian days, she was always and mostly considered as a great goddess and a protector)

Any closer to adding sleep mode on 3.xx? its the only thing stopping me from using this Great Dev though, keep up all the good work!

 

[CTCaer]

This is the next step.
Better utilization of the Security engine and sleep mode re.

 

[sirAnger]

i can use it with SD file v5 ???

Yes that worked for me. No ini files or modules needed to be updated.

 

[tecfreak]

... and a heavily stripped chainloader to load hekate or coreboot/u-boot from the sd card as the next step?

 

[Azel]

This is the next step.
Better utilization of the Security engine and sleep mode re.

Looking forward to this

what do you mean by better utilization of security engine ? ^^

If it's like other security engines, I can probably use it as memcpy to save some hundreds of milliseconds here and there.
And also I want to fix the verification of pkg2. It may be needed in the future.

 

[CapitanSburro]

works like a charm cheers mate

 

[jczoe]

Took over 2 hours but i was able to finish a backup with 3.1. Thanks!!
