Hacking Question about restoring from 2.1

[ll0rT]

I followed the Plailect's guide very carefully and got otp.bin. Now I'm in 2.1 and have several sysnand backups. I selected sysnand restore option to restore my sysNAND_original.bin that I got from OTP helper but it said backup size is wrong.

I checked its size and its 1.300.234.240 bytes, which is supposed to a Samsung NAND chip size. (https://github.com/Plailect/Guide/wiki/NAND-Size). Then I checked my other backups made from Gateway launcher, and realized that they are 1.979.711.488 bytes which is a Toshiba NAND chip size!

So, what should I do? Which brand is my NAND chip? Am I screwed?

Edit: I forgot to give some info. It's a New 3DS LL JPN. Also I have Cubic Ninja.

Download the newest OTPHelper, there was a bug that was fixed in v0.84

Thank you! I didn't realized that a new version released 7 hours ago.

I'm still confused though. Why is my size of backup made from OTP helper has Samsung NAND size and gw launcher's backup has Toshiba NAND size? I'm still scared to restore 1.2 gb backup while my gw backups have larger size (and ther're working, I used to restore them without problem).

I'm not sure of the technical details, but it's something to do with redNAND: https://github.com/d0k3/OTPHelper/issues/9
The different sized NAND backups should work fine according to the dev

I tried restoring the 1.2 gb one and worked! Thank you for help. Mods can close this thread now.
