Re: HP BIOS unlock tool
Hi, I'm not so expert, only my first experience, anyway:
1. - - > did you try to Use clip with power supply connected? I had failure at first as well before doing in this way.
5.- - >could be not resoldered correctly? I don't really know, but try to connect power supply and after the clip on the chip (disconnected from usb PC) and check if the 5V LED on the miniprogrammer is lighting, if yes it means good connection with the chip, so it could mean the chip with the mb is soldered well.

Re: HP BIOS unlock tool
Finally had succes! Password removed on my 2570p. Thank you to all the members for the support and mainly @RethoricalCheese & @mkvsbs, you're great! I Finally used win10, CH341A programmer software 1.18 (the only one that has worked for my CH341A miniprogrammer Black edition and my chip MX25L12845EMI-10G. I would finish with some notes; I tried also V1.13, but my chip is not available,in the list, V1.29 crashes at saving file after reading, 1.31free doesn't detect my chip correctly. I've also read the chip with V1.18 on winXP and it works fine as well,...Leave a comment:

Re: HP BIOS unlock tool
Do you mean Win10, win7, xp... Tried only Win10 up to now, i can try win xp. Or do you mean dirrerent version of ch341 programmer. I've only used V1.18 up to now. The V1.13 has not my chip, and 1.39 looks for ch341 blue series, not the black one we have, because the scatch of the zif in the program a is the opposite. Can you post a link of newer version than 1.18? Thanks in advance....Leave a comment:

Re: HP BIOS unlock tool
Hi guys, I read 3 times my bios file, it is the same compared with HxD. UEFI tool and ME Analizer look good as well.
HPUnlocker also worked well modifing the bin file close to the string "BIOS administrator..." like the other unlocked file posted in the forum.
But now I've a problem, I unplugged and plugged again the clip and I did more 3 readings, they still are the same, and look good with UEFI tool and MEanalizer
but they are different than the ones before the unplugging ...
What's the correct one?...Last edited by Ap78; 06-05-2020, 07:56 PM.Leave a comment:

Re: HP BIOS unlock tool
Thank you, always because "better safe than sorry" I've extra question, because now I cannot only virtualize... but the risk is to brick the system...
1. if the twice reading doesn't match or uefitool and meanalyzer fail, can I use this dump bios
[url]https://www.badcaps.net/forum/showpost.php?p=777786&postcount=1[/url]
2. or even writing is risky
3. in this case I need to do something more after the flash, or it should work in my pc without any modification to adapt the new bios to...Leave a comment:

Re: HP BIOS unlock tool
1. Remove battery: do you mean only power battery or CMOS battery as well?
2. So, is the VERIFY command passed after the reading the key point to understand if the reading has been succesful?
3. When do you mean to check with Uefi tool and Me analyzer? After the rewriting the bios?...Last edited by Ap78; 06-02-2020, 03:46 PM.Leave a comment:

Re: HP BIOS unlock tool
I know this is very particular request, could you say us some tricks to have succes using the clip on 16pin chip. My chip is MX25L12845EMI-10G. I'm not so confident in myself using soldering hot iron, because I've not hot gun. Thanks...Leave a comment:

Re: HP BIOS unlock tool
Oh no! I've just bought a clip, and I've not soldering hot gun. I've only a soldering iron, but I'm not enough skill ed on it... Have you some advice to suggest in case of clip or is it really impossible to do?...Leave a comment:

Re: HP BIOS unlock tool
Finally do you suggest to use the clip or desoldering?
1. Can I try to read 3 or 4 times the .bin BIOS file and compare them to check they are the same so be sure my SOP16 clip had worked well ?
2. Can I refer to this video to plug the clip on the chip?

or do you have better video reference?

Re: HP BIOS unlock tool
Thank you very much, at first.
I have two more question before start:
1. Can I read/modify/write the chip with 16sop clip, or I need to use the heat gun like I read in this post?
[url]https://www.badcaps.net/forum/showpost.php?p=902174&postcount=12[/url]
2. How can I check if the BIOS will be unlocked successfully before reassmble the laptop?Re: HP BIOS unlock tool<br /> <br /...d/modify/write...Leave a comment:

Re: HP Elitebook 2570P Working BIOS
Did you only flash the file with IC programmer (ex. CH341A and clip sop16 on the chip)? Nothing more to do? PC started unlocked without any more modification? thank you....Leave a comment:

Re: HP BIOS unlock tool
Hello guys, it's my first post here, so I want to wish you the best.
I tried Mazzif tool in DOS way for my 2570p, but it didn't remove the bios psw.
Will HPUnlocker tool be effective for my laptop model?
Had someone already tested modifying their proper dump bios and reflash?
Thank you in advance...Leave a comment:
