Re: HP EliteBook x360 1020 G2 6050A2895901-mb-a01 BIOS
Hi all, I ordered EC and BIOS chips online, seller claims they are preprogrammed and should start PC once soldered in. However, here in forums I read that using other PC (same model, motherboard, etc.) chips might brick your PC. Is it a case here?
I already used Peste's cleaned BIOS without DMI information after which PC does not boot and even original dumps cannot boot it. I suspect it is either bricked or one of the chips might be malfunctioning and ordering a pair of new ones is my last resort.Leave a comment:

Hi SMDFlea, I do remember you have replied with a new cleaned dump but now it's gone. I have been away and did not have a change to try it out. Could you please upload it again? Thanks in advance....Leave a comment:

Hi SMDFlea, do you recall what did you do or what was the problem with this particular [URL="https://www.badcaps.net/forum/showpost.php?p=871646&postcount=26"]case[/URL]? The blank screen and white/yellow flashing sounds familiar and the guy eventually had it solved.Re: HP EliteBook x360 1020 G2 6050A2895901-mb-a01 BIOS

First I read "soldered" in the same places, but then it made me think, could I have mixed them up.. Probably not, but I will double check that.
Also, due to many flashing attempts, I have the ICs unsoldered and in the adapters, connected to either Rasp Pi or the motherboard through 8 pin connector. I wonder if the relatively long cables have any influence on communication with motherboard, I assume it runs 200-400 MHz depending on dual/quad mode while RPi has max 16MHz (?).

I know! I was so sure at the time that they are fine and now I am in doubt. Anyways, the RCunlocker shows the info, except MAC address being zeros. Thus, I assume something is read for sure.
To answer your question, I just checked it, no it does not boot. Same behavior....Leave a comment:

Re: HP EliteBook x360 1020 G2 6050A2895901-mb-a01 BIOS
Just checked it. No, same behavior. I assume it's either the dumps were incorrect or HW damage. Would you know if I can do some merging of the locked dump with a clean one to produce something that might work? I think peste did somethin similar.
I am not sure if there is anything wrong with HW. The EC and BIOS ICs are working, I checked the pull up/downs around, seems fine.
I actually read all the threads with EliteBooks 10x0 requested to be unlocked. A few similar cases of fan spinning, LEDs flashing...Leave a comment:

Re: HP EliteBook x360 1020 G2 6050A2895901-mb-a01 BIOS
Is there a way to check whether the dump was made correctly? I have done 5 readings of each, all were verified, all are bit-identical. I do program with Rasp Pi, chose low speed, etc.
I know it is a dumb question, perhaps there is a straight forward answer to that....Leave a comment:

HP EliteBook x360 1020 G2 6050A2895901-mb-ax2 schematics
Hi, I suspect some pull up/dows/decoupling were blown away during hot air, I would like to check that on schematics. I am interested in circuitry around U365 and U366. Thank you in advance. -
Re: HP EliteBook x360 1020 G2 6050A2895901-mb-a01 BIOS
Hi Vesko356, thanks for a attempt. I do get the same result no matter it is your cleaned dump, the one I made with RCUnlocker, or the one I bought from someone:
In sequence:
Orange/white LED flashes for a few seconds, 7-10 times;
All off;
White power LED powers on, orange is on, fans try to kick in but stop;
White LED off, orange stays lit, fans kick in and go to 100%, nothing else happens.
I am starting to think something wrong is with motherboard, even though it was...Leave a comment:

Re: HP Elitebook X360 1030 G3 remove password BIOS.
Hi Alex, slava ukraini. I am not sure why nobody is not thanking you for this post, but here is my appreciation. I have been looking forward for this all around the net.
Is there a change you know where the BIOS structure is defined for i.e. HP? I would like to understand the structure and be able to find areas of interest (i.e. UserCred, AdminPW etc.).Leave a comment:

HP EliteBook x360 1020 G2 BIOS password removal
Hi all! I hope you can help me out with these two dumps. There's a BIOS password I need to remove. Thanks in advance!
MX25L6473FZN and W25Q128JVPQ, 6050A2895901-mb-a01 motherboard.
Pete has previously provided me a Orig+P90_0138.rar but it does not work, led is flashing, fans spinning, black screen.
If you have info what needs to be cleaned and how, please share so I can try fixing myself, thanks....Leave a comment:

Re: HP EliteBook x360 1020 G2 6050A2895901-mb-a01 BIOS
Hi peste,
Thank you for the cleaned version. As I understand, 8 MB dump should stay the same?
I tried to write the cleaned 16 MB dump, but the notebook could not start. Flashing yellow/white charge light, tries to start, fan speed increases until max and it restarts to the same.
I flashed the backup back of 16 MB chip, but result is the same - fans high, yellow/white led flashing. I wonder what is the problem?Leave a comment:
