    hi guys i have a big problem to my switch, i restore my nand to 5.1.0, but switch wont start,i haven't burned efuse,i check with bricmii and i have 6burned efuse but restore isn't success and i look at this guide :https://gbatemp.net/threads/switch-wont-boot-after-restore-nand-but-can-run-rcm.540019/ when i insert the boot0/boot1 fron 8.0.1 this replace myboot0 and boot1 but isn't my fw and switch has a blue screen i checked again with bricmii and my burned efuse is 9, i try to downgrade with manual choji, but when i extract the biskey didn't work because nand and boot isn't same, now i have a biskey it's work from hekate 5.0 but i follow this guide https://gbatemp.net/threads/how-to-...nofficially-without-burning-any-fuses.507461/ and nothing appear, i don't know why, the test from biskey it's ok i derive the biskey from sdsetup, because biskeydump didn't work and also briccmii tell me an error: https://imgur.com/oUad7Bd
    the question is: there is any way to upgrade swtich to 8.0.1 with manual choji and not chojiNX? or a method to launch .nro from exemple hekate? because i don't enter to CFW and OFW i hope to have been as clear as possible

    thanks so much

    What firmware were you on before restoring to 5.1.0, was the 5.1.0 nand backup restored with correct boot0/boot1?

    You can try loading lockpick_rcm from Hekate menu to get your key and use that with Choidujour to rebuild your nand.

    lockpick require atmosphere sept file, usually it doesn't boot ofw because they boot0/1 and the firmware installed doesn't match, if you don't have a matching pair and no keys that Choidujour can use you are screwed.

    i have a sept file, and yes i have the key, but i don't know when try manual choi didn't work, the biskey test is ok but when i arrive in this step:
    1. Return to the main menu, then select ‘Launch > FS_XXX-exfat_nocmac_nogc’ where XXX is the firmware version you downgraded to.
    2. Make sure your system successfully boots
    didn't work.

    when i try to substitute the boot0 and boot1 from mattytrog package i change 2 boot from 8.0.1 fw and now i have 9 burned efuse, for this i ask a method to upgrade manually to this version
