Re: Maximus P2 Flash File Frp Dead Recovery Fix Customer Care File
Roser Blazado
Great info! I also screwed up my asus motherboard with the windows-based flash utility :-( I Have a P5B-plus vista edition, but i think this will also work on this model since it also has a SPI_J1 connector.
I have some questions though. Is it neccesairy to use the power-molex of another computer? I want to use one of the connectors of the crashed computer itself. Or isn't the motherboard allowed to have any power during the operation and should I disconnect it from the power-source? Should the CMOS battery also be removed in that case?
Concerning the software, should I first clear the BIOS, or can I straight away write the ROM file to it?
@Bob
It is possible that it will work without external power with the motherboard in standby (powersupply hot but motherboard not turned on yet). I tried this, but at the time my cable wasn't right. If it detects your chip id as ffffffh then something is wrong. You could also try flashing it with the motherboard actually turned on.
If that doesn't work then you can still use the power supply in that machine, though. Disconnect the power supply from everything, connect your flashing cable power, then on the main motherboard power connector, take a paper clip and short the green wire to a black wire. This will turn the power supply on.
As for clearing the bios, I was unable to get it to clear it. It worked anyway by just flashing the rom.
Good luck!
thanks for the reply. Did not get it working though. I could the cable made by a friend (I am not that handy). The first problem is that the molex cable of the flash cable is female. The molex of the powersource also. Thus, they cannot be connected. To overcome this, I just cut one of the molex cables and stuffed the wire in the red hole of the flash cable. Still no luck. It still says fffffh.
Here is the strange thing. I connected a multimeter to one of the molex of the powersource. The red cable of the meter to the 5v red pin of the molex and the black wire to the black pin. Nothing. It does not show any voltage. I checked the meter with a battery; it works. Even more stranger, my motherboard has a small LED, indicating that it is getting voltage.
Am I missing something? I didn't understand your 'short the green with the black' comment. Do I have to short a cable that is coming from my powersupply, or on the motherbord itself?
I am clearly missing something. I got an old computer from the attic. i disconnected all the wires from the power source to the motherboard and other devices. I then connected the sensors of my voltmeter to the red and black female pins of a power molex. Nothing.
OK, I am a bit further.
My shorting the green and a black wire from the powersupply of my spare computer, the power started running and flash cable could draw power from this. And... after this I could flash the BIOS via my laptop!
However, after this, my PC still wouldn't post. Even the LED lights don't come up and no voltage can be read from the molex plugs. I tried shorting the green and black again from the powersupply. No result. I tried shorting the green and black from the motherboard connector. No result. If however, I plug in the powecable to my motherboard AND at the same time short the cable while it is plugged in, by computer spins up: the LED lights go on. The same after the BIOS upgrade failed, but before I cleared the CMOS. As soon as I take out the paperclip, everything powers down. So the computer only runs / keeps spinning with the paperclip in. Even then no booting, no video, no POST.
Any ideas? I have the feeling I am close. Since the BIOS rom is restored, everything shouls be the same as before. I have the feeling some hard reset has to be done for the changes to kick in.
Thanks for this great wrap up of the spi flashing procedure. I did not finish my cable yet to flash the P5B i send to heaven with using the asus flash tool for vista 64 (do not do that!!!). Im not the electronics guy so could you please specify what diodes i need? From reading the internet i get the impression that it almost doesn't matter. But when i go to my local electronics store i have to tell them something. Could you please provide a specific diode type that i could go out and buy? Id prefer the cheapest ones that will do the job. Thanks in advance and keep up the good work.
mondo, when I short the green and black wire while the cable is connected to the motherboard, my power-on LED burns and the harddisk LED. I hear the harddisk spinning up and for about 5 sec. seeking. After this no more, but both LEDs stay on. During this, the fan of power-unit runs, but not the case-fan or, more importantly, the CPU fan.
Since I succeeded in flashing the BIOS via the cable, I would expect things going back to normal. Is there any chance my power-unit has to be reset or something, and the problem is not anymore with the motherboard?
hello again :) thanks for the immediate reply. I've been at the electronics store and they gave me some strange diodes that did not properly drop my voltage. A friend helped me with messuaring and soldering. We achieved a voltage drop of 1V with 6 diodes. So obviously they are not good.
So we used a spare ATX power supply, shorted green to ground to make it run without attached board and stuff. Then we used one of the orange +3,3 line and grounded it to the parallel port 18 too.
I did cheer as the spipgm worked for the first time, but the board is still dead. I dumped the P5B flash to disk and compared it with the file provided with the P5B motherboard cdrom. They do not match. How can i fix this? Is this bad timing? Bad wiring? User error? Any idea? I provide some pictures an plan to update this blog, please have a look:
@Diego, either the chip doesn't have power or something isn't wired correctly. Also, make sure your parallel port is enabled in your bios (on the flashing computer) and set to use address 378h. I actually ran into this and my parallel port was disabled in the bios.
@Bob,
If I understand you correctly, you successfully flashed the bios, but now you can't get the computer to turn on? Hook everything up like normal and plug in the power supply and make sure the power supply switch is on if it has one. Does the motherboard LED light up? If not, the board isn't getting standby power. If yes and it won't turn on, you may have other issues.
@mondo, that is right. I succeeded in flashing the BIOS with the cable. The power-unit is connected properly to the motherboard and the light on the motherboard lights up. However, if I check the voltage of one of the free molex-plugs, it does not give any power. Furthermore, if I press the power-on button on the frontpanel of the case nothing happens.
If I short the two pins you mentioned, besides that the green light keeps on burning on the motherboard (as before), the fan of the power-unit turns on and a voltage can be measured on the molex plugs. Furthermore, the power-on LED in the frontpanel lights up, as well as the harddisk activity LED. No videosignal though, no POST, no beeps and no CPU or case fan start running.
Strange, isn't it? All this problems occured after a bios flash. I would expect things go back to normal after reflashing it with your cable. Any clues what could cause this behaviour and I could investige some more? I tried out another power-unit, so I can rule this out as a possibility.
Am real desperate, because I cannot buy another mobo with the same chipset in the shops anymore. Since I have both a RAID-0 and a RAID-1 set up on only two harddrives through Intel Matrix technology, I am afraid a new motherboard will not recognize my RAIDs and the problems will only increase :-(
Thank You!
Using this information, I ressurrected (sp?) another P5B D-Wifi. It was killed by the Asus Windows flash utility. I built the cable, used the 3.3V supply on the ATX connector, flashed, and IT WORKS! I used an old Printer cable and an IDE cable that I chopped up. $0 Cost.
I just tried this on my asus p5b-e motherboard which was killed with a windows flash, and the first time around it seemed to work however it still would not boot
so i hooked it back up and it reads that flashrom jedec id, type: 000000h
status = 00h and everything =0
however if i do it while the computers power is switched on i get a ffffffh so somethings up.
what happened and why wont it work, ive checked all the cables etc
???
Hi,
A few days ago, a computer with an Asus P5B as mainboard was left running (as normal) and when I checked on it (not omre than an hour) it was running all fans at max, screen blank (no signal), HD activity light on, and power LED off. It wouldn't power off except at the wall. When I try and boot it up again, the CPU fan spins up, and after a long time (15-20s) the graphics card spins up, but nothing else happens. The power LED was off, and the HD Activity light was on (as before). Some of the time the card spins, less frequently it doesn't even do this.
Thinking the issue might have been the PSU (and noticing a faint whining noise coming from it), I replaced it with another, but the same symptoms as above happen. According to my DMM, the buzzer (which does not exist on this model) would be sounding continually. Obviously, I've cleared the CMOS and disconnected HDDs, all but one stick of ram, tried in various slots, and tried it without any GPU. nothing changes the symptoms.
Right now, I believe it to be one of 2 issues:
Either an odd power fluctuations caused the PSU to fry the MoBo/CPU
or
An unknown issue caused the BIOS to be wiped/damaged.
Is there any way of telling what the issue is? I don't recognise the symptoms, but am guessing this might be as a result of BIOS damage, which is why I'm posting it here first.
Thanks
