  Hello!

  It is not possible to downgrade the BIOS version, because only the most recent BIOS is available on the European driver Toshiba page.

  As far as I know that an ASP (authorized service provider) would be able to downgrade the BIOS.

  However, the new BIOS that is available on the Toshiba page should make no trouble.
  In your case I would recommend you first access the BIOS and set the defaults.

  Good bye

• Aspire V3 - 772G. Downgrade BIOS

  Hi all

  After you have installed the version 1.15 of the BIOS of my FAN works almost constantly. Is there a way to downgrade to version 1.13?

  Will, Te, full reset to factory settings?

  Thank you very much and good day,

  Alexander

  Yes you can downgrade your bios, look at this topic:

  http://community.Acer.com/T5/notebooks-netbooks/aspire-v3-772g-driver-issues/TD-p/127713/page/2

  The decommissioning of the BIOS is as follows.  Unpack the VA70V108.exe with something like WinRar or 7-Zip and then in the platform.ini find "[Bios_Version_Check]" and edit "flag = 1" to "flag = 0" after that, save the ini file and run the InsydeFlash.exe as administrator. That's how I lowered my BIOS.

• Re: How to make a downgrade from the Bios?

  I did a Bios upgrade (2.30), but now, the avid media composer do not work...
  How can I do a downgrade bios?

  Thank you.

  Hello

  Downgrade a BIOS you will need previous, traditional version of BIOS.
  These BIOS is not available for download.
  Only the most recent victory based BIOS is available for download.
  So that means that only Toshiba authorized service provider would be able to downgrade the BIOS.

  But I put t think that this new version of the BIOS is the reason for the question with avid media compose.
  What problem do you have exactly?

• Satellite L50 - C - 29V BIOS 1.50 downgrade to 1.20

  Hello

  Anyone know if
  (a) the laptop allows firmware downgrades?
  the old firmwares b) are stored somewhere publicly?

  Best regards, Timo

  Hello

  Why would you do that?

  Your is a new pc was released end of 2015 if I'm not mistaken. And if I'm right, he made out with 1.50v bios already. Since you did not already done a bios update and are good all workers, why would you want a downgrade to a version which had never been installed on your machine?

  Be really carefully when it came to an update or the bios down since it can make your machine does not work properly or does not work. This isn't an OS upgrade/downgrade... I hope that you understand that the bios should do to a machine.

  Now to answer you:

  (a) I don't know
  (b) http://support.toshiba.com/support/v...tentId=4004549 (this may help, but be careful because this isn't for your machine!)

  PS: I am a user that you are, and I assume no responsibility in case your downgrade bios does not.

  I want to downgrade BIOS because since I install 2.6 on Vista 64, I have a lot of freeze (PC freeze 30 seconds each about 5 minutes). After updating the BIOS, I don't have this problem.

• Satellite A300 - BIOS downgrade after upgrading the BIOS

  I did an upgrade of BIOS of victory of version 1.6 of 2.10 - at the recommendation of the Toshiba site, for my laptop A300 1N0 - model PSAGUE.
  Touchpad no longer works. I have 2 operating systems, XP and W7 is the same.

  I start the laptop with the Windows Live CD and Ubuntu Livecd and nothing has changed.
  The mouse works, but the touchpad is still dead.
  Any advice?

  How can I find the old version of the BIOS to do a downgrade?

  Try contacting the Toshiba authorized service provider in your country. They have access to the database of Toshiba and the access to the Archives of BIOS.
  I'm sure that they can send you old BIOS version and you can downgrade BIOS on your laptop.

• BIOS problem, how downgrade

  I'm updating the bios to 2.14 to 2.21 on my aspire E1 - 571. MY video ram on version 2.14 was 128 MB and is now on 2.21 64 MB. How downgrade bios 2.14 because 64 MB is bad for the game, when I go to install 2.14 has error message "Comparison of bios problem" Please help, help, help

  Erkedo,

  Avoid any problems flashing the BIOS to an older version. Did you do that there is no way to manually change the video memory setting in the BIOS?

• Satellite A660 - boot problems USB after BIOS update

  Hello

  I own a Toshiba Satellite A660 and have recently updated the BIOS with the latest version (1.80). Since then, the laptop freezes on the splash screen (the one with the Toshiba logo) whenever a USB flash memory is attached.
  It works without the memory flash connected and if I connect it after I enter the starting or the BIOS Setup menu. I can even start her like that.
  As far as I'm concerned, this is a serious regression. Is there a way I can downgrade to the version of the BIOS, or any other way to solve this problem? I rely heavily on external USB drives.

  Kind regards
  Claudiu.

  Claudiu salvation,

  That is really interesting, I have to say so I tested on my new Satellite A660 and Transcend 4 GB USB Stick. Well, I also installed 1.80 BIOS but I can t view this problem HARD drive is set as first boot device and all the other BIOS settings are default. The Toshiba screen and Windows computer starts as usual.
  No problem at all!

  Have you tested different USB devices?

  In General, it is not possible to downgrade BIOS. It is possible to an authorized service because Toshiba on page you can download the latest version only but I doubt it s a bug in the new version of BIOS because it works on my A660.

• Satellite A500D - where can I find the older version of BIOS?

  Hello! (and sorry for my English)

  I need to install an older version of BIOS for Satellite A500D - 10 h (now I v1.20, updated on 6 November on the official website).
  The problem lies in the thermal BIOS options to which fan too loud makes noise. Or can there is a newer version? Before, I understand, so was v1.10. I ask to Word a previous image BIOS for A500D or command prompt, where I can find the earlier version?

  Installed Vista x 64,

  Thank you

  Hello

  As far as I know isn t possible downgrade BIOS. You can download the new versions on the site of Toshiba but decommissioning, we must move to an authorized service provider. Technicians can downgrade the BIOS.

  If you n t know where to find the nearest ASP, you can search in the Toshiba page:
  http://EU.computers.Toshiba-Europe.com > support & downloads > find an authorized service provider

  Good luck! :)

  I have a Toshiba Satellite A500 with fan noise problem.
  It has been partially resolved the upgrade of BIOS from v1.20 to v1.30, according to this thread:
  http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?threadID=46719&start=0&TSTART=0
  

  Yesterday I updated the BIOS v1.50, and the sound of the fan returned.

  I know that people have problems to get the downgrade to BIOS, so I describe the process in this thread:

  Thanks mate for sharing this with us

  But perhaps you could use the v1.5 BIOS and could reduce or reduce the activity of module cooling in Vista/Win7 power management settings.
  It would be interesting to check it out

  In any case thank you for this info
