Official Coffee Lake Thread/BIOS For ALL SkyLake/KabyLake Clevo LGA1151 laptops

Look here under P https://www.manualslib.com/brand/clevo/laptop.html

 

If you cant find it you may need to take out the motherboard and examine the 8 pin chips. Be careful of what chip you flash, if you accidentally flash the ec chip your motherboard is as good as gone!

Edit: I had to do this with my clevo P870dm-g as there was no picture of where the bios chip was located. Took a good 5 minutes but after typing in the chip model numbers and using the clip to auto detect the chips I found the bios chip.

Most likely it will have winbond written on it.

 

So it looks from that like U17 or U18. They don't seem to be findable on the underside of the system. I have been struggling to see how to remove the keyboard from this system. The service manual doesn't make this easy. I don't really want to make my day worse, so am hoping for some insight

 

There is a hole next to the cpu socket, put a screwdriver in it and pop of the keyboard. Push until the top lifts off basically, don't push it too much, you could tear the two keyboard connectors!

Keyboard is attached to chassis with magnets, yes MAGNETS

 

I saw two screws marked with 'KB'. I assume those are the only ones needed to be removed?

 

Yes, do that before trying to push the keyboard off.

 

I found U16. Does this look like the right chip?

 

this is great news I guess u used BIOS from this topic (that supports 9th generation, right?)

 

Yes, that is the correct eeprom. It's 8MB (64Mbit, per the label) and there's only a single chip of that size on the motherboard. It also stores the ME, so make sure to write the full 8MB rom and not the 5MB bios-only versions. First thing is a backup of the chip's current content, of course.

Btw, note the white rectangle on the pcb near one of the corners of the chip's footprint; it matches pin #1 on the chip (dimple/dot in the corner). That way you can't inadvertently flip it 180° if you'd de- and resolder the chip, aligning #5 to #1 and vice versa (they're U-shape sorted).

I need some further help. It looks like these are the values on the EEPROM:

BH1619
25B64CS1G
POU913

The SkyPRO programmer tells me that it cannot identify a corresponding device. It looks like this is a GigaDevice part, but it's difficult to know for certain. How should I configure the SkyPro to work with this particular EEPROM?

 

Yes, it is a GigaDevice; use GD25B64C, if the programmer knows that one. If it does yet it still cannot id the chip then you need to make sure it has proper contact with pin #1.

And did you desolder it or did you use a clip? Not all systems and chips can use ISP, so you may have to desolder first, if you hadn't already.

 

That does not show in the dropdown. It only seems to show GD25L... and GD25Q... devices under SPI FLASH / GIGADEVICE. SkyPRO 6.8.3.821, showing no updates available.

I have a clip available, but I'm stuck currently by the lack of the appropriate chip in the list.

 

The Q model is compatible with the B type, so that will do fine. Remember to make the backup first, then make a second one and do a hex compare of the two dumps; if the programmer's setting is correct then they'll match.

 

So this has been very....interesting. Even with the programmer, the only BIOS that seems to work with this system is the one from Origin. Neither the Coffee Lake nor the Cannon Lake P750DM BIOS will work with this system. They write and verify just fine, but the system boots to a black screen. Baffling, but at least I have a working system back (although it's a shame not to be able to get the firmware updated)

Thanks very much to all who came to my aid in this misadventure.

 

I believe the Coffee Lake Refresh Thread has more BIOS for the Cannonlake.

 

Yea the thread your looking for is posted above if your using 9 series cpu.I hope u get it working.Maybie desanke will do this for the lower class mb like w650kk1.The GPU might be weak.But 8100 runs like abient

 

http://joxi.ru/L214GaaT83oE4m
VT-x off ;(

 

Hey,i need help,with my p870km1,wich is the bios chip here : https://postimg.cc/t1hYv3gb

Thx. https://postimg.cc/t1hYv3gb

 

In w650kk1, Vt-x is enabled.

 

You're looking for the chip labelled U12 on the board, per the manual here :

https://www.manualslib.com/manual/1300989/Clevo-P870km.html

You might need to take apart the machine to find it on the board. It might be under the keyboard, for example.

 

Is imposible to finde this,i found 2 of them,but iam not sure this are the right chip,i dont finde that u12

 

Your top pic where you can see U12 written in white on the motherboard next to an outline that surrounds the BIOS chip

 

Thnx,but now i got other error with my sofi sp8:

 

Have you connected the clip properly. If not try again.

Otherwise, it looks as if the chip is damaged from the corner as it is missing the top casing.

 

Hey,no,is not damaged,is only paint,yes i connected proprely,i did that test pin with the programmer and is ok i get something like ID error

 

What programmer do you have, have you updated the software program to support your chip. ID error sounds like the chip isnt compatible with the flasher.

 

here is the error,i will check now,thnx

I think i have the latest ver.And the chip is in the list of this programmer : SOFI SP8 with FlyPro software.

 

I still think the programmer doesn't support this chip. When I tried on my skypro auto detect didn't pick it up until I flashed new firmware onto it.

If you can, try another programmer I prefer skypro as it has the most compatibility and features.

 

Yeah i will try with pro too,but with this programmer is very strange,i can read and save the bios from the chip but i cannot erase or program!!!

 

Careful assuming that the read is OK. I had that with a poorly contacted clip in my first runs and the output file was all zeros on the disk : you have to check the saved file is somehow OK. Assume nothing, be very paranoid.

My clip was quite fussy as well - I had to work fairly hard with it to get a good contact sufficient for the programmer to behave itself.

 

yea

My saved bios is ok,he is the same like the original 8mb,but i cannot flash that s the problem.

 

Someone previously mentioned that some EEPROMs aren't programmable on-the-board and might need desoldering. I have no particular knowledge to suggest whether this might be the case for yours, however.

 

This could be a possibility too. However, @Clevobest have you tried another programmer yet?

 

Yes i will try to desoldering and see if is working or not,thnx.



No,not yet,i'm still waiting for that skypro to coming,maybe in 2 days is here.Thnx

 

Given the risk involved, I'd suggesting waiting until you have tried the new programmer before resorting to desoldering. That's the sledgehammer in my view.

 

Yes,this is what i was thinking too!

Man this is very strange,in my laptop i have MC25L6473F and in manual is GD25B64CSIGR for BIOS!!!Wt....???

 

That's perfectly normal.

A 64Mbit SPI eeprom is just that, same as you don't wonder about the particular brand and model of an 8GB DDR3-2133 stick (generally speaking, of course). Sometimes you'll even find a 128Mbit chip when the laptop model only really needs 32Mbit, but it's just whatever they have available, is compatible, cheap and has sufficient storage size.

 

Oh,i understand now,thnx.

 

Yes, the manuals are good, but always look directly on board.
There are 2 main sources of error:
1. the clip ; recommendable is Pomona...
2. the programmer ; most of the cheap ones work with some chips, but there can also occur errors.

By the 2 error sources one can create a lot of consequential damages and further error sources.
Bugs in hexcode etc....

The GD25B64C is the right chip for the P870...

You have to program and read this chip with the ICSP interface. A higher quality program has such interfaces. In addition the power supply must be plugged in at the same time to the board, then it goes perfectly!

 

Hahahahahaha!!!!I am soo happy,fix it again,this incredible!!!!My laptop is alive again,thanks to all,incredible.............................

 

Would be nice if you explained your method.I know reading previous post's helped me understand,but if you could explain.ie programmer and steps to success.I see theres a few with the same prob you could help.Thx

 

Hi there,is not complicated,i recommend you the programmer Skypro,i try it with so many and all are not working with this chip from p870km,(and no,the chip is not the GD25B64C)you need to open the whole laptop,becouse the BIOS chip is under the touch pad,and than you need the original BIOS,or the last BIOS from your laptop,and connect the pomona clip to the BIOS chip and to the Skypro programmer and than open the bios file in Skypro and push auto,and you have your bios again working,it is not complicated trust me (if you have that Skypro).

 

If you want to program and delete the Bios Chips of the P870xx with a programming device, you have to remove the upper case cover anyway. This is how it works.
You can use the Skypro, I recommend this TL866II Plus. This is a professional device, which makes different programming voltages, without adapter, and it has an ICSP(In-Circuit-Serial-Programming) interface. Also, it only costs a bit more than the SkyPro2, which means there are 2 different ways to program the chip without soldering it off. This is always the last variant. And of course, as described above in my article, the clip is crucial for good results.
With the P870xx the Bios chip (GD25B64C) with the above recommended device with the ICSP interface works very well! (Master-Slave mode) The only important thing is that the power supply is plugged in - Important! Thus the chip has the supply voltage and it works without problems.
It is also important that you perform a read operation after each programming process and then save the ROM. Afterwards you make a comparison with the original ROM with a hex program to exclude errors. Sometimes errors can occur due to the incorrect fit of the clip!!!
The MainEC chip of the P870xx can be programmed in another way. Simply connect the pin assignment to the 40-pin socket and it can be programmed.
Also the software of the TL866II Plus is constantly updated. In the month 2 times. Buy this and you will have much less problems! You can also program all sorts of chips. Also the MX25U8033E of the GTX1080 e.g. goes with it easily.

 

Skypro is the best of the best for simple users, there are better ones out there like @radolf mentioned but for the price it's actually amazing how many chips it really can support.

@Clevobest glad to see your clevo working again!

 

Thank you,yes i'am agree with you,Skypro is the best.

 

Like I said, I was just giving back my experience. The TL866II Plus is, I think, just as easy or difficult to use as the Skypro!! These are the possibilities and ways I wanted to show. In the end everybody decides for himself!

 

I am not saying that TL866II is not good,but i tried 4 of this programmer and i spent more than 120€ and nothing was working and this Skypro did the job in 2 minutes!!!

 

I have tried 2 and the 3 is the TL, and this one works perfectly for me!
