The tristate is a pin of the southbridge chip ---> https://www.psdevwiki.com/ps3/South_Bridge
As far i know is not connected to any other component (it goes to the pad only), so lifting the pad or cutting the line doesnt causes problems
Btw, you should cleanup the area (with ear sticks + alcohol) to try to see if there is some rests of the copper... incase there is something thats good, not enought to solder in it, but enought to use the trick im going to mention

You can solder a wire (ground) to a needle and touch the line with it... but handling the needle with your hands (or the hands of a familiar or friend) is not relliable... you know... if for some reason the needle slips you can create a shorcut and kill the southbridge (or whatever other component you touch with the needle)
The good way to do it is by building one of this "tools" i mentioned here ---> https://www.psx-place.com/threads/f...-and-error-reporting.30100/page-3#post-248523

The second tool i mentioned is better because it gives more freedom

Btw, you could use that same tool to touch in the tristate pin of the southhbridge... is just the southbridge is soldered by BGA so it doesnt have pins and we cant see the solder pads :(
From the lines around it (either in the same side of the board, or the opposite side) there should be one for tristate... but it looks there is no pinout for it

hey @sandungas This Is some complicated. Is there any other way to PS3 super slim power on. Or like any other alternative point to PS3 keep on

And thanks for your this suggestion
 
Hello, there is an alternative to getting data off the NOR chip without powering on the ps3.

The safest option i find is use a teensy 2.0 +++ board and awg 30 wires to the correct nor points with a regualator chip on the teensy then plugged into a usb 3.0 slot. This will give enough power for both teensy and nor chip - ive tested this myself so i know it works.

Other alternative is use an atx psu and the 3.3v, and connect to the nor vcc pins directly.

Thanks For your help
but I am a bit confuse the post you share with me he used to backup from dead motherboard but my motherboard is all good only tristate point Is lift up and in the post he used E3 Clip cable to connect with nor chips but I have a E3 linker you know E3 linker is connect to motherboard to flash it and also I have already PS3 backup I only want to flash the backup to PS3. In your opinion this work for me ??

He is suggesting to use an alternative method to read/write the NOR chip, where you keep the PS3 unpowered all the time (it never boots because you dont have to push the power button)

The idea is to have te PS3 motherboard without any power (there is no need to connect the PSU), and "inject" the 3.3v directly to the NOR chip
The 3.3v needs to be generated externally... either with the regulator used in teensys.... or with a standard PC ATX PSU
You know.. and standard ATX PSU have 3.3v output (the orange wires as far i remember)

OK But my Doudt is He used E3 Clip cable but I don't have clip cable I have a e3 linker so I need more volt because I not only use Nor chip I use full motherboard??
 
So, basically you need to power the e3 linker and the NOR chip without powering on the PS3 motherboard. Because you cant keep the ps3 on due to brick, you need to do the way i suggested.

ATX psu > 3.3v > NOR chip (or some form of 3.3v source, a mobile charger? voltage regulator?)
E3 linker powered by external source > connected to NOR via wires for the data line etc as per pic below

So the e3 linker pins - https://i.imgur.com/IWa5FQU.jpg - just an example need to find your motherboard pins reference

Just solder the BCC and VCC to a 3.3v source (not the ps3 motherboard)

OK But my Doudt is He used E3 Clip cable but I don't have clip cable I have a e3 linker so I need more volt because I not only use Nor chip I use full motherboard??
