Firmware upgrade using Linux tool, requires no hardware

[Falkentyne]

Are you using a desktop?
I forgot, but didn't they say that "some" computers won't expose their i2c addresses?
I flashed mine using a laptop, but I'll try booting through my desktop and see what happens when I get to that point.
I faintly remember the i2cdetect -l showing some field or grid of data but I forgot...was a few months ago....then the -1 command afterwards showing some other stuff on the right.

I do have a camera
Maybe i'll take a picture.

Yes I indeed used my desktop. Don't have access to a laptop right now.

[Falkentyne]

I'm playing a game but I'll boot to Ubuntu after it's over and take a picture.

[Falkentyne]

Ok
Here's what sudo i2cdetect -l shows on my desktop.
Radeon adapter (just what the Benq is connected too on dvi)


Here's what sudo i2cdetect 1 shows. A big pile of nothing.


Sure enough, dumping bus 1 showed nothing but X's.
There was nothing until I moved to bus 5, then did this.



So you can see the Benq detected on address 0x50, bus 5.
(The Benq is connected through the DVI port).

On my laptop, the Benq (on VGA) was on bus 0.

I did not even get any feedback from the commands (except sudo i2cdetect that only gave a map of the available parameters, such as -l etc). I'll try again tomorrow and see if it works..

Oh yeah, in case it still doesn't work I can take a picture for you so you see what I mean by getting no feedback whatsoever. Lets hope it works though, I tried it for so many hours today

Are you using an Nvidia card?
I (think) remember someone saying something about Nvidia hardware not exposing its i2c address, but I don't know what happens if you have multiple display adapters in a system.

Also, when you used the WGET command, did you use a capital O or a number 0?
just to make sure, it should be -O- with the dashes around it.
that's a capital -O-.

Yes I used capital -O-, I had to originally double check which it was.

And yes, I have an Nvidia GPU but I tried with iGPU priority on and monitors connected through motherboards own DVI and VGA ports. I've asked a friend to loan his laptop so I can try with that if everything else fails. I understood that's a bit more foolproof, right?

If we do it with a laptop, should I use VGA or DVI (if both are possible)?

[Falkentyne]

VGA should be easier. Use DVI only at the last resort.

I'm really curious to know if you get the i2c list on that laptop.

If you read back earlier in the thread, some people had flashing failures on 'some' laptops (this resulted in a bricked monitor, BUT this only bricked the DDI/DC channel, though the screen was unusuable. The i2c port was still available). They simply changed laptops and reflashed and it unbricked and upgraded.

I went through the previous pages and I can not see anyone who had the sudo i2cdetect -l fail to give any input. Most of the problems were people asking what to do if multiple devices appeared (e.g. a Radeon and an integrated display at once). And I'm a complete Linux noob, so all I can give is what worked for me.

I'm almost tempted to flash back to V2 to test something, but I won't bother. I almost remember 60hz not strobing quite as nicely on V2 (smoothness) as on V4. Then again I could just be high on something....

*edit* found 1 other person who said the i2c command did nothing.

But he switched to his sister's laptop and it worked.

[Jiigeri]

That sounds a bit intimidating to be honest. I basically have access to one laptop and if that fails and renders my monitor unusable.. It takes me at least 2 weeks to get another laptop to try it on again (which is my girlfriends who studies at another city).

I'm a bit baffled.

[Falkentyne]

Well its your choice.. Don't flash if you don't feel comfortable, then. The rest of us just did it and are happy with the results I think it's worth it.
