that's what I figured: some sort of soldering issue after modifying that byte.
Hello my friendIt was the first time I did something similar, yet I found it simple. The only thing is that we now very little about the NOR so unless you have a lot of dump to compare to try to restore the one corrupted or you're trying to fix the WiFi/Bt area, it's pretty useless.
You mean this:Hello my friend
I do not know what is the configuration of the Jumpers
of the CH341a programmer,
maybe you have a photo.
Yes, but the problem is that there are 2 types of clip: sop16 to dip16, sop16 to sop8. The photos show this. Which would be the most suitable to use?

Is possible dump nor PS4 Spansion model FL256LAIF01 ?
I just dumped mine, though I'm having issues. No 2 are alike. If someone has a CUH-7215b 7.50 bin to share, I'd be grateful!

Yeah you can downgrade back to whatever you had earlier. My program will be able to confirm if you can and show you where to make the patches as well as patch your nor. But you need to dump your syscon. Lots of effort. I'll be making a super basic step by step guide soon enough though.Hey
Long story short:
I have an PS4 with the now newest firmware because I left it in rest mode while walking my dog.
So therefore I can't jailbreak it anymore.
After discovering this thread (and yes I've read the big red warnings) I wanted to ask if how I could modify my NOR backup or and where I could get one that could make it possible to downgrade to 9.00.
Thanks in advance
Peace!
can you patch my nor and sysconHello, friends!
I switched the active slot (9.50 ->9.03) and downgraded the firmware without a dump 9.03! But we need a new chip R5F100LLAB 0.50mm pitch.
my is R5F100LLAA 0.65mm pitch.
this method will fix the bios error loadbios -8 and checkUpdVersion
I attach my syscon for example and analysis (all logs and extra records are deleted)
nor patch: Filing (FF) offset 0x201000 size: 16 (ULTRA MEGA BRICK SYSCON , USE ONLY NEW SYSCON)

Actually no but I did this procedure just onceThanks @sautzer. Great tutorial. A couple of YouTube videos say that CH341A is supplying 5v and will fry any 3.3v chips. Some are doing modifications to their CH341 to make sure it constantly supplies 3.3v. Based on your picture, you did not seem to have modified yours. I guess I'm only asking did you face any voltage issues with this programmer tool?
Depends on your luck. What if you fry your chip before you could make a dump? The procedure to convert from 5v to 3.3v on the data lines of ch341a is very simple, just lift one leg and connect 2 wires right. I advice you to do it.Thanks @sautzer. Great tutorial.
