aku punya PS3 baru 4 bulan dah makan penangan dewa langit semalam...

router goreng.... PS3 ethernet and wireless control IC rosak..

dah x leh on9 pakai ps3... geram aku kena main off9

bli router baru pun no use gak.. PS3 wireless and ethernet also damaged..

Since the 2.5 update the PS3 has a Recovery menu with the following options:
but i dont think it can downgrade...

Restart System: Restarts the PLAYSTATION®3 System.
Restore Default Settings: Reset all system settings back to default.
Restore File System: Checks for corrupt/missing system files.
Rebuild Database: Rebuilds the OS for the PLAYSTATION®3.
Restore PS3 System: Fresh restore; Deletes everything and starts from Scratch.
System Update: Update the PLAYSTATION®3 System

How to get access to service mode

Make sure the PS3 is turned off,
Press and hold the power button on the PS3 it will power on then power off.
When it's off press and hold the power button again until you hear two consecutive beeps.
It will ask for the controller to be connected via the USB cable,
Turn on the controller and you will have access to the menu.

Note: this is actually user recovery mode.. not the actual service mode. It doesnt affect the bootloader, which is used for PS3 first power on.

to downgrade, must able to acess bootloader.
console must be opened and a jig + software + PC is connected to an I2C connector on the PS3 (u can see on the mb there is always unused connectors rite)




ohh.. theres this device called infectus which claimed can help clear the NAND and downgrade
dunno never tried b4.. juz stumbled upon

Since everyone like to talk about fan.

today imma gonna share about fans and its relation to YLOD. On how fan influences YLOD. (please bear in mind that fan is not always the cause of YLOD)

The hardware that detects temp is called a "Thermistor".
As for temperature Data detection, it does at intervals of ## seconds, and decide by # times accordingly.

Study this graph, see if you can understand it. It's simple! (Please strictly note that values is not actual or fixed, it can always be changed by software means, and not to be used as a reference!)


Some of the conditions that can lead into yellow light.

1. Thermal Shutdown
When detect Temp data that becomes thermal shutdown.
Shutdown while display yellow light.
Go to "Standby" (red light)
Doesn't change user setting data.

2. Check condition of fan
Only when rotating it checks for fan. If "fan error".
Shutdown while display yellow light.
Go to "Standby" (red light)
Doesn't change user setting data.

3. SYSTEM ERROR
fixed at high/max (depend on fw version) speed.

How fw effects fan speed.
1) Different model have different fan with minor voltage-speed-ratio difference.
2) FW is common!
3) Hence some fan may have higher rpm and some lower while voltage (4 steps, low mid high full) is same.
