PS3 Bricked ps3 after flashing ofw dex on converted cex to dex ps3 slim cech-2104a.

Hello, I have ylod after flashing ofw dex 4.81 on ps3 that was converted to dex from within evilnat. I switched around other firmwares before flashing 4.81 dex ofw (last one before this was rebug 4.84.2 i think) and wanted to try out the ofw dex firmware too. Later on I found out that is a big no no and ended up bricking my ps3.
I got an e3 flasher, pulled down tristate point to prevent ylod, dumped the nor chip bin and applied patches like in this guide: https://www.psx-place.com/threads/guide-unbrick-a-ps3-after-an-unfortunate-ps3xploit-flash.21750/

dump checker gui failed on ros0 and ros1 hashes; dump checker python from console passed checks.
the coreos bin that I used was for 4.84 as the gui dump checker showed version 4.84 for ros0 and 4.81 for ros1. after patching, i proceeded with flashing, removing the soldered wire to tristate point, but the console still does ylod.
I think it's because I didn't use 4.81 ofw coreos bin (which i cannot find online). Can anyone help me repair this ps3? I can provide the dumps if required.

update: i tried flashing default nofsm patch based on evilnat from dump checker gui, now the ps3 doesn't ylod, but stays on green led. I only managed once to get to "cannot start ps3" screen after plugging in the HDD on which was the ofw Dex 4.81, but I turned off the system to plug in the blu ray drive and never seen a screen output since, regardless if I try going to safe mode, or other drives. I think the Ps3 wants a Dex kernel because has idps converted, but the evilnat based patch found in dump checker is cex based. I was able to extract d-pex 4.92 latest version using PUPExtractor_1.00 and got CORE_OS_PACKAGE.pkg, but I don't know how to turn it into .bin that is usable for dump checker gui. Am I going in the right direction here?

another update: I managed to extract the coreos bin file (called 'content' I think) from rebug 4.84.2 drex using puad gui (evilnat was too new, or it just errored out), patched & flashed but still no screen output, with no ylod

update no. 699:
I extracted coreos bin from evilnats 4.92 latest dpex using puad 2.0 and updated the keys with some I found on a random forum on here (up to 4.92 nice), patched and flashed, but still the same case - no output. I suspect it's the cpu solder joints or pads on the pcb at this point, as at one point the ps3 began to ylod even with tristate point pulled down (I used a ln2 pot as a heatsink for the cpu; after reseating it on the cpu the system didn't ylod). As it once gave an image with the original nofsm patch based on evilnat's cex included in dump checker gui, maybe this is how you can recover from flashing ofw Dex on converted console.
