Re: [REQUEST] Thinkpad L490 Bios file ?



do you mean i should buy a replacement chip ?
or do you want me to try to flash W25Q256/GD25Q256 file ?





I bought ezp2019 with wson8 extension board ? should i need to desoldered it ?
Actually im not good in using solder iron , so if i can prevent to use it , i will prevent it

btw , if my chip is not supported do you have any bios flasher to recommend that can support my chip ?

Thanks...

Thanks for the response

I saw from the link that TL886II is the recommended spi programmer
would like to confirm if is this the one that they were talking about (see attached image) ?

also , i saw ezp2019 on the list of recommended flasher , but i found ezp2023 ? can you take a look if this will work

Re: [REQUEST] Thinkpad L490 Bios file ?

any one ? ,

also is there a way i can extract the original bios from the bricked laptop ? i saw users from other forums which i am not currently member , i just saw it from google , they extract their original bios rom even it is was bricked then post to that forum and then the thread owner fixed the problematic bios rom then reupload the firmware .

Re: [REQUEST] Thinkpad L490 Bios file ?



I Used the menu from OpenCore there is nvram reset there .
actually on my DELL laptop, resetting nvram with OpenCore is working without problem . but on this laptop L490 it is very strange though i saw on lenovo forums , resetting nvram assumes to be safe .


I did not read anything regarding on bios backup .

and now , I'm looking on how can i bring my laptop to life , i believe this is BIOS problem since i found out that there is other user at lenovo forums experience the same...

Hi ,
Last week i bricked my Lenovo Thinkpad L490 , i think NVRAM reset caused it.
because i'm trying to install hackintosh to that laptop . and as per forum they recommend to reset the nvram ,

So after i install hackintosh , and reset nvram then restart the device , my Laptop is not booting , but there is a sign of life because , because it has a LED light , Power on light , ESC light is on and Capslock light is on, but the laptop has no activity . it stays on black screen .

i believed NVRAM reset messed my BIOS rom.


now , I'm planning...
