Topic: ATIFlash/ATIWinFlash does NOT work on the latest/current Windows 10 update (Read 7545 times)

Sorry if I write in an old post, but it had to be logically completed.

There is always a solution to the problem, the question is different, are you ready to make this decision.
In your case, reinstalling Windows 10 will help.
And most importantly, you need to use the proven version of ATIFlash compatible with BIOS

I have this error with that driver on Windows 7 64bit 7601 with AtiWinFlash 2.84.. And it hangs after the message that flashing is ok (sometimes it even doesn't appear). But! Somehow the flashing works! I just have to reboot via power or reset button. And just one time today it even didn't hang!!  So, does it mean that this driver isn't needed to flash? I think I'll try AtiWinFlash 2.77 today..
Update: my bad, that is just a 32bit driver and thus is blocked.

There is another way to get around this problem that has worked for some people.

1) make sure you have your monitor attached to a non bios modded card
2) uninstall current AMD driver then reboot.  Windows will use generic driver for GPU.
3) run ATI Flash GUI and do whatever mods you want then reboot.
4) reinstall AMD driver reboot
5) run Pixel Patcher for newly modded cards and reboot

Modded cards should now be recognized by system and ready to go.

This worked for me.
Updated three out of four AMD rigs to 1803 and was able to flash the RX 570's using Atiflash (opening command prompt in admin mode and flashing using command line).

This works flawlessly. Just make sure you open CMD as an adminstrator so everything you run is as admin and it will work perfectly. Atiwinflash graphical kind of sucks because it doesn't give much information about devices and only shows 2 devices but running this with ONE device connected ensures there will be no mistakes as to what flash is going where.

USE THIS. Do not look past this post because if this doesn't work for you, you did one of the steps wrong or used the wrong flash. Opening CMD as administrator is a must.(you right click over cmd in cortana and tell it to run it as administrator).

I have NO idea why Windows up and decided to crap on the ATIWinFlash Utility with the latest version of windows THAT MS WILL force you to update to. I guess a shady driver it doesn't like without you running as absolute admin? In any case, it's a bit of a pain to unplug cards and shifting stuff around but it works and will not brick as long as you use the right rom.

Oh in my case, I flashed it in a full slot. No clue if a riser is any different but it shouldn't be as the riser has access to the same parts of the card for updating the rom as a full pcie slot does.

Use this latest AMD/ATI ATIFlash 2.84 it works

What Windows 10 build and AMD driver version?

Please help I have the same issue, except for me, every time I click the "Load" button on the GUI my entire PC freezes.

RX 580 8Gb hynix flashing modded bios normal without errors...

Hi!

Now we can open the v2.84 in Windows 10 but....

I Have a lot of problems saving the BIOS and can not write any Modded bios...

It always says "Error reading from ROM"... I change Risers, change GPU.. and still the same problem with my RX570 8GB Micron memory.

Exccelent!!!! What interesting - I'm looks for it about hour ago, it was no new version! They are published it just right now!

UPDATE TODAY!!!!! 2.84 works on new windows!!!! WOHOOO THAAANKS

Are you running it from an administrator command prompt, using the command line pasted a few posts above? It seems almost crazy that it works for some people and not for others?

2.67 works, but it doesn't support cards Polaris and up.

Ok, tried to run in administrator mode the versions: 274, 271, 417, 411, 407, nothing works after the April update... 

I know this doesn't make any sense but I read on discord that a guy by passed this problem on windows 10 build 1803 using an older version of ati flash. The thing is I can't remember which ati flash version he used. And I'm not sure he was telling the truth either. I'll start testing older version one by one, and I'll let you know if It worked out.

thanks, with the portable version works good for me

i run cli as admin, i get no errors, only the message put a key, thats all, and reinstall of win is no solution for me
