Well, i know how to get into bios, building computer more 20 years.. but you wrote:
To Downgrade then Boot your Laptop in Bios Maintenance (may be You have to use NOVO Button)
I haven't any Lenovo laptop so I son't know perfect It (just experinces by users and knowlwgements)
then Set to ENABLE RollBack option and save Settings !
But i dont know what is bios maintenance, you mean just normal bios? And what you means by rollback.. i dont have any such option in my Bios, i have only usual options in Bios. Do you mean boot in legacy not UEFI mode or something like that.. possilibility to disable Bios flash i saw as option in bios, only on some Intel desktop boards..
Please upload here all Bios Menu Tabs Screenshots (pictures = photos) so i will look by
myself them and let You know !
I can see only into Bios Code and there is this option then I have to see if It is visible or not !
If not visible then I will indicate a way to activate using FalseClock Method !
Let me know
Regards
Reupload the v.2.52 here result file please !
Regards
Link is still same as above:

But i got, some red lines during process and bios file is only 4MB - and i sure that bios had right setting, i tried it now, same result.
- other rom backup through FTP -has 12MB and was created ok - link is also above.
Sorry, i maybe misunderstod, but i tried to update Bios through 2.52 linked lenovo utility, but i got - message that Bios dont match this system and couldnt be installed, so i cant upload to 2.52 bios here, should i try it download from Freedos USB flash, with $0AH4000.FL1 file from 2.52 installer folder, or something else?
Im sure that rollback is enabled in Bios.
I am sorry
!
I think You have to get the Tools (SPI PGM + Clip) to make this job !
It's easy and are cheapers so look here :

If You will get Them I will help You to flash the Bios Mod following you into any
step and gettin all support !
let me know

Hmm, Hardware way, if there is not Software way, im not interested, will buy whitelisted modem instead.
I lost patience, i was prepared to brick this Lenovo crapp, so i have tried moment before use flash utlity here for 2.52 with Lenovo official 2.52 bios, but i got.. message unable to remove write protection or something like that.. So as you wrote there isnt probably way..
We have got free and full unlocked a lot of MoBos wher is more easy by Tool SW and
more hard using Tools HW so SPI PGM and Clip !
You can find many Tutorials and Guides here just googling
