Need help. Bricked switch? Autorcm ON, but Switch not turning on even after changed battery

So here is the case. I haven't used my switch for a couple of months, then I decided to play couple of games, but to play them, switch asked me to update my firmware. All this time Switch's battery were dead. Easily I turned it on and charged it. I did a safe update to a new version without a problem, but in a software for a safe update (Chou-smthng) I chose a FAT32 SD card option, but my were an exFat. So after updating switch, it couldn't boot futher than just a ATMOSPHERE logo. I decided to format my card from exFat to FAT32 in order to boot further, so which I did. While I was transferring files from my PC to a fresh formatted SD card, I decided to go for a store and left switch NOT charging without sd card inside. After an hour, I came back and realized, that my switch is not turning on, I thought it because it had an AUTOrcm mode on, so i went websurfing, tried to charge it and push a payload, tried to press On button for a 30 seconds and then charged, tried to charge it with Dock, with Nintendo adapte and with 3d party adapter. Tried to unplug and plug battery and do everything again. Now I've put a new battery inside of my switch, Seller told me it was charged, but payload still unable to push. PC and Phone (android) can't see any RCM devices. So I couldn't and still can't push a payload.

UPD
Well, I solved half of problem, I just made a Jig from aluminium foil and used it with a new battery, and I managed to get into Hekate, BUT now I'm in endless reboot of Atmosphere Logo. Any suggestions?

I just downgraded my Switch to 6.1.0 OFW (found keys and OFW at google), installed Atmposhere and then updated. Well, it worked. so everything is fine now.
Buy I think, that restoring NAND backup will help too, I just had no memory on SD-card for placing rawnand on card. So I decided to downgrade by using memloader and HackDisckMount.
