Homebrew [RELEASE] OTPHelper - OTP dumping & downgrade helper

[Khangaroo]

in >2.1 is patched the exploit

I thought only 3.0+ was patched

because you think the downgrade version for maximum access kernel is 9.2? it's the same, the max version for access to OTP is 2.1.

technically 3.0, 2.2 has issues I think due to a different NATIVE_FIRM, but OTP still isn't locked.

 

[RacsoSakuraba]

well is the same, this work max in 2.1 after all.

Actual dumping of the OTP.bin (0x100 or 0x108, only on FW < 3.0) included for convenience. Not shown in the screenshots, this is in the ARM9.bin.

OTP Helper is saying I have only 333mb available, but windows say 2.16gb, why?
It can't backup my sysnand because of that...

Windows may be wrong, especially if there is a large number of small files on this SD card. Try to make some room on it.

 

[Asia81]

No, I'm sure Windows is right because I can paste 1 nand backup without error, and some large cia.
It's the same thing with Decrypt9.
I'm trying to copy all my files to my PC, then I will format using SD Formatter, and re-paste all files, we will see.

You say it works in D9, but not in OTPHelper? What did you use to format this SD card? Don't tell me it was Easeus Partition Manager :/.

 

[Asia81]

I didn't say it work with D9. I said D9 show me also the same false size. I format always using SD formatter by panasonic, and emunand created by EmuNand9.
No worries, i will format once more

This possibly made things infinitely easier getting the otp.bin for me. So thank you for that, though I have a question.

What are the benefits of having the otp0x108.bin? I can generate mine using my dumped OTP, but what benefits would that bring?

So...I recently updated my OTPHelper to the latest version, from v0.81, but whenever I try to chainload it (with Luma) I get a black screen, I'm not sure what's going on, does anybody else?

Why do you want to run it with a9lh already installed? Whatever you want to do, I'm pretty sure D9 is a better bet.

Already got D9, OTP is just something I'd like to have in case it was ever needed that's all, thanks for the reply anyway, much appreciated

You should not, D9 will be there for all your needs. Tbh, I never cared much for a9lh compatibility in OTPHelper, so I might have missed something. Will look into it later, but it should be a non-issue.

Just for my understanding, does the one click setup touch the sysnand?

Because it seems to be all about rednand on 2.1, and suddenly there is a chance of bricking and the sysnand needs to be restored in Plailect's guide, even though it wasn't changed before.

 

[Krude]

Well duh, the whole reason it's dangerous and we have this helper to make it as fool-proof as possible is that the 2.1 firmware HAS TO BE on sysnand. The OTP is inaccessible if you boot anything higher than a FW 2.1. When you boot emunand, the system is already running (from a higher versoin firmware boot before) and the OTP is locked.

the guide does the following. downgrades rednand/emunand to 2.1 then once that succeeds it copies the rednand/emunand to sysnand. then you get the OTP. then you put your normal sysnand back on.

New release v0.88, more safety for you. This is new:

• NAND dumps are now verified via .sha files
• Removed irrelevant Wifi warning (just pull out your battery if you forget)
• A set of 'emergency' files will now be autodumped in One Click Setup
• Some fixes for smaller bugs

Have fun!

I can't for the life of me get OTPHelper to boot. I put the arm9.bin and arm11.bin files in root and the OTPHelper folder in 3ds. I've tried it through Browserhax, straight from CtrBootManager and through Ninjhax 1.1b and 2.7. Black screen all the time...
Any ideas?

Edit: Tried the release before latest and it worked on the first try.
