Hacking Downgrading from 6.2 to 6.1

[tonioss22]

Hi guys, so i see everyone asking for a magical way to downgrade from 6.2 to 6.1 without the nand and boot files. My question is how do i do it with the nand and boot files, i see everyone saying use choixdujour (not nx) but i dont find any post about choixdujour, the only one is see is from raj and it's how to do a backup but i dont really know if that's the right one, what step to skip or to not skip, i have downloaded all his tools and everything. I see i need biskey to restore from a nand and boot file with choixdujour apparently? anyways any help would be helpful. Also i did try to restore it with hekate but the only thing i get now is a blue screen on normal boot (obviously expected) and when i try to boot in CFW, i get a unknown package1, version (= '20181107105733') from rajnx and package 2 magic invalid on reinx which is why i was looking into restoring from my nand via choixdujour. Thanks in advance.

also i saw other ppl saying they couldnt restore the backup on hekate when in 6.2 but i had no problem doing it, didnt get any error message...

Not from the experience of doing it but from what I've heard you've likely burnt your fuses on 6.2, therefore, you need to recover your < 6.2 backup and keep it on CFW that skips fuse checks. It should work from what I know just means you always have to use RCM to boot into CFW which is pretty much what we have to do anyway.

As i said in the post, i did try to restore from the rawnand and boot0 and boot1 with hekate. But everytime i load a CFW i get the errors mentionned above

você pode ir de 6,2 para 6,1 se você tem um backup de nand e boot0 / 1


edit: backup nand boot0 boot1 6.1
