(adsbygoogle = window.adsbygoogle || []).push({}); Okay Ill explain this in the exact steps I did it and well its just plain up not working as service mode NEVER shows up ever. Does anyone know if it matters if you have multiple accounts on your PS3?

1. I am running a fat PS3 with 3.50 FW.
2. I power the system COMPLETELY off, so there is no red light
3. I put my FAT 32 USB with file 1/modded PUP file into the rightmost usb slot on the PS3.
4. I use the back button to turn on the power(so its red)
5. I quickly then press the front power button along with the eject(no game in drive) button at the same time
6. It takes a little while to load up and the orange and other small led light flashes for a few seconds
7. It takes me to the XMB to select which account I want
8. I hold the PS button down for a few seconds to allow me to choose which user I want.
9. I select the user that was already highlighted(default) and hit X
10. I go to the main XMB and NO service mode or anything else for that matter.

What am I doing wrong?

Thanks.

see if this helps

Its for the TI-84 but same concept

1. Install the PS3JB App (v. 0.08.0001)
2. Open the PS3JB App on your calculator. (APPS->PS3JB)
3. Choose Option "5" (Options)
4. Make sure "Stage 1 and Stage 2 Payloads" is set to "none". Make sure "FW. Compat. Opts" is set to "none". Make sure "Use Device 6" is set to "No".
5. MAKE SURE "EMULATE JIG" IS SET TO YES
6. Save your configuration.
7. Connect your calculator to your PS3 and press option "1" (PS3 Jailbreak) on your calculator.
8. Do the power cycle like you normally would to jailbreak your PS3.
9. You may see some screen flickers. You will not have a picture on your screen. The PS3 will shut itself off.
10. Format a USB flash drive. Make sure there is nothing left on the flash drive.
11. Copy over the modified 3.41 update (PS3UPDAT.PUP) and the first Lv2diag.self file onto the root of your flash drive. There should be nothing else but these two files on your flash drive.
12. Plug the flash drive into the right-most USB port if your PS3 is laying down, or the top USB port if it is standing up.
13. Power on the machine. Don't do the normal Jailbreak power cycle. Just power it on. You will get no picture. You will have to wait until it shuts itself off agin, which took me about 10 minutes. DO NOT get antsy and think it froze on you and shut it off prematurely. Give it up to an hour before doing anything drastic.
14. Once the PS3 shuts itself off again, plug your flash drive back into your computer again and delete the "PS3UPDAT.DAT" and the "Lv2diag.self" files. Once deleted, copy over the second Lv2diag.self file to the root of your flash drive. Again, this should be the only file on your flash drive.
15. Once the file is on your flash drive, plug it into the same port you had it in before in your PS3 and turn the power on. Again, just a normal power on, no Jailbreak power cycle.
16. It will stay at a black screeen until it is ready and then shut itself off. Once that is done, remove your flash drive.

Too bad I don't have that calculator(srs). :bye:

You need a jailbreak USB stick or device in order to get into factory service mode. After that you can use the files to downgrade.
