(adsbygoogle = window.adsbygoogle || []).push({}); For the people who PS Upgrader doesn't working i post a tut here:

First of all you have to have a Blank USB and a PS Jailbreak (original no hole in it)
You must login or register to view this content.
You have to had PS Upgrader V1.1 V1.2 or V1.3 I tested with V1.2 so we only use that flash_windows thing.
Downloads:
ProxyPS: You must login or register to view this content.
PSUpgrader: You must login or register to view this content.
PSDowngrade SELFS: You must login or register to view this content.
And the PS3UPDAT.PUP file you want.

Step 1 - We must decompress Proxyps in to the desktop. (USER/Desktop!)
Step 2 - Put the proxyps and proxyps source in to a folder name it: ProxyPS.
Step 3 - open command prompt and type:

    cd desktop/proxyps

Step 4 - You will be in that directory now type in:

    proxyps XXXXXXXXXX

(X is your serial number)
Dont be unpatient the cmd is loading and downloading the files, when it finish you will see another time the directory above.
ex.

    C:\Users\Desktop\ProxyPS>

Step 5 - Now in the ProxyPS folder there are upgrader_X and prog_X copy that to the PSUpgrader directory and the C:\ too
Open a "blank" cmd (another time), and put:

    cd C:\Program Files\PSUpgrader\PSUpgrader

Step 6 - You are in the PS Upgrader directory! now type:

    flasher_windows upgrade_X.fla

(PUT .FLA IN!)
(If it says FLASH FAILED=3 try again, if it says FLASH FAILED=0)download the files of proxyPS again.
Step 7 - Now you will see Succesfully upgraded or something like this in cmd and a green light on the PSJB you are able to do the downgrade.

Downgrade (Copy & Pasta):
Step 1 – Insert PS Jailbreak device that has been reprogrammed as PS Downgrade into your console
Step 2 – Turn on console using same boot method as PS Jailbreak – Press Power then immediately press eject. You will see your console turn with PS Jailbreak lit up with red/green light followed by green only, Then it will turn off.
Step 3 – Turn on console to make sure you are in factory service mode. You will see a huge red box on the screen saying Factory Service Mode, once confirmed please turn off console and remove PS Downgrade Dongle
Step 4 – Program any blank usb with 2 files , A) modified 3.41 pup B) Lv2Diag.self (file 1) These must be the only files on the usb key and must be placed in the main directory of the flash drive.
Step 5 – Insert this new Flash drive into the right USB PORT of your console ( It must be placed in the outermost right port) and turn the console on. You will see black screen but you will see flashing lights on the console (yellow) and on your USB key
Step 6 – Wait 3 minutes for the system to install the old FW, towards the end the power button on the console will start flashing green and then your console will power off.
Step 7 – Remove the usb key and turn on the console , you will still be in factory service mode. Please verify you have downgraded successfully to version 3.41
Step 8 (Optional) – If you wish to downgrade to any older firmware you can not follow step 4,5,6 using any regular firmware PUP. (You do not need to use modified custom firmware now that you are on 3.41)
Step 9 – Insert flash drive back into PC , remove the PUP and Lv2Diag.self and install only LV2Diag.self (file 2) on the USB Flash Drive
Step 10 – Power on your console, after 10 seconds it will power off
Step 11 – Turn on your console with no USB inserted and you will be out of factory service mode into retail mode with your chosen firmware version installed.
Here is the proof from 1 spanish friend (only the factory mode proof but i do this, is REAL)

Gadget Asia scamming? really strange... my don't have the hole and im downgrading normally i buy it from ps-downgrade.com

SOLVED! Replace the 3.41 pup with 3.50 and the 1st lv2diag.self and put it in the rightmost USB port. Turn it on and it will flash 3.50 and turn off in 3 min. Then delete the 3.50 PUP and copy the modified 3.41. Make sure you have the right PUP, because that's why it wasn't working! Then flash 3.41 with the same method. Verify you are on 3.41 and delete all the files on the usb and copy the 2nd lv2diag.self. This will put you out of service mode and you have to set up your PS3 all over again.
