IdeaPad 720s-13ARR: if the bios won't be updated anymore?

I know this problem have been asked but it actually wasn't solved

I like the ideapad 720s 13arr and but there is a problem with my laptop,I bought an new  "old" ideapad 720s 13arr,the new bios have been release but I can‘t update,as the it said that

"2.Due to security reason if your current system BIOS is less than or equal to v29 that will not support update BIOS to V38, and will be keep BIOS V29 awlays which shipment with RS2 preload."

I know the new machine can be update beacuse I have a new ideapad 720s 13arr before it ran into problem with v37 bios and I exchange to this one.

in v37 it said the same thing,but I am now wondering if lenovo engineers are still trying to fix the security problem and when our machine can get updete

if lenovo just give up support for machine with v29 and v28 bios?I am really worry about my machine won't get any bios support anymore.

Re: IdeaPad 720s-13ARR: if the bios won't be updated anymore?

Hello!

You are right, this problem has been discussed here in several threads, but there is no solution or official reply from Lenovo.

 

As you are the only active person here that has or had access to both types of machines (2?WW and 3?WW) may I ask whether you have noticed any differences? Unless we get an answer from Lenovo this might give us some clues what was changed in the revisions.

 

Furthermore it is interesting to note that there was an updater to 29WW which was removed and replaced by the 38WW which does not update 2?WW. Is this a mistake or otherwise what is Lenovos pupose with it?

 

So come on Lenovo, give us an official statement!

 

Thanks!

Moriarty

I don't think there are any difference between new machine(3x) an old machine(2x) in motherbored as I saw this.

[link removed]

maybe need a translator

it's not easy but they actually successful update to 3x from 2x

so I think that is just a software problem and lenovo didn't solve it

but there is a difference between new machine and old machine,the old machine use Samsung ssd,and new machine use others,I forget what it is but it not good as Samsung's

I can confirm that the update via hardware bios programmer works fine. The blog missed a lot of tricky details.

In the next few days I will publish my own version in English and German. :-)

Now i am on Bios 6kcn38ww and started with 6kcn28ww.

I think it is just a bug in the 6kcn2*ww bios versions.

It could also be related to the Windows 10 version on the recovery partition.

Maybe this can not handle the current Bios versions and they want to avoid problems with that.

Hello!
Good to know that 38WW seems to work on "old" (ie 2?WW) machines.

But though I am interested in computers I do not have access to a bios programmer and have never done so before.

I think it is very disappointing from Lenovo to create such a chaos without giving any explanation or help even after several threats on this topic.

I will wait and eventually return my machine if they don't clear this up.

Glad to know that my machine actually can be updated to 38WW.

 

According to that blog above, it seems that 38WW fix Youtube issue.

I hope Lenovo update 38WW so I can flash it in my laptop sooner than latter. Otherwise, i will send this thing back and switch back to mac Smiley Sad.

 

For your info, latest GPU driver clocked at 200MHz instead of 300MHz in our current version.
