I charged full baterry and I can make update of bios officialy ...so Happy,even if the UUID is not match with the box but now is recognized by Lenovo online guarantee also can make updates of bios and in boot bios settings all field now is filled and not Invalid like before...so Thank you so much Lost_N_Bios

I assume you can't update same way, this is mod BIOS, usually you can't flash mod BIOS with stock method.

Please show me BIOS info page as it is now with BIOS I gave you in post #12, as I requested. I only put some info, and I need to see the BIOS with that info. UUID I may or may not have put, but if I did put it would have only been the one you gave me.
I think I only put the following, and then waiting to see new BIOS image
MTM:81FB005URM
Lenovo s/n :YD04KB1H
Factory id:GXSC WMAC:505BC2BFCFB5

* Edit, I didn't see your post above until I posted this reply. Good you can update mod BIOS now with fully charged battery, maybe that was reason all along and you can flash mod BIOS on this system any time

@alesul - Get me new BIOS image of that info page, and I can fix your UUID probably. I left that as it was originally, was waiting to see if the above changed applied as expected or not before doing the UUID, because UUID area was not labelled as such so I wanted to see other stuff first.

I atach picture,and Lenovo verify everithyng before update bios all this info like UUID and info,but you can see just UUID is different than on my box one.

@alesul - Sorry, your sentence is jumbled (Doesn't make sense to me) And your images do not load properly, the two that do are duplicates
Please put all images in a zip, thanks. Also, be sure to see my edit and request at post #17, been waiting on that image so I can fix rest

Anyway, here is new BIOS with UUID now, take new image of BIOS info for me if it's wrong still

Is the same photo and the only one I have,I uploaded many times to be sure cause the forum tool have some errors.I am tired about all this problems and I want to pay some services to do that cause is to much trouble for a product new by 2 weeks with 2 years guarantee.Thank you for all the help.

@alesul - Then you only need to upload one photo, or you can upload it in a zip here, or to any file host, then I can download it.

Anyway, I fixed BIOS for you above, did you try it yet?

no,If is based on 30 firmware is uselles for the moment! Thank you!

@alesul - it's based on whatever BIOS you sent me, that we've been using this whole time?!? If you need new version BIOS modified, then send me dump from that BIOS I will fix it for you again.

I allready attached bios v36 in post#15 if you want to download!

@Lost_N_BIOS buenas tardes, tengo el mismo problema con una lenovo Amd R52500U 81FB00HKUS RYZEN 5, Como puedo editar la bios para que funcione
