Help to replace broken screen Glo HD 2015

[buithang]

Hi all.
I have a Glo HD 2015 (E-ink Carta), Its screen was broken.
and I hardly find a replacement screen

My question is:
Can I replace its by screen of old Glo (E-ink Pearl)?

Although they have different resolution:
E-ink Carta HD 1072 x 1448
ED060KG1(LF)
vs
E-ink Pearl HD 758 x 1024
ED060XG1(LF)

But they have a similar cable.

Does my Glo HD is compatible with the old screen?
Or do I have to do to make them compatible.

Please help. Thank you.

I was in the same case than you 18 month ago and nobody knew (as it seems). I didn’t dare to try myself (because i didn’t want to risk 50$ on nothing)...

Have you already a perl screen ? if yes, no harm should come to to just plug and see

It's not compatible.

Hic, So sad
Thank cramoisi and frostschutz for your fast help.

Here's a link to the screen you need.

Yup, at that time, there was no ED060KG1(LF) on aliexpress... now, there is no more gloHD in store. Sad thing since the screen is only 25€ away from a new device.

Yes, the new screen is out of stock
I've ordered a new kobo.
Thank all for your help.

Hi.
I mistakenly ordered the kobo glo screen and the screen works on glo HD, but due to low resolution impossible to use (characters do not fit screen, only partial view). If there would be a possibility to tell the OS to lower resolution to 1024*768 as you can in other OS, could be a solution, but I have no clue if this is possible - how to configure screen resolution.

[frostschutz]

you could try booting a regular glo sd card (or any model that has this resolution) and see what happens. amazed if it works at all

[cramoisi]

yes ! try it ; somebody could probably provide you with a glo 'sd' image for knowledge'sake

[JSWolf]

Ask in the thread for Glo images and Davidfor can PM you a link. Then you can try it.

My first reaction is that using another image isn't going to work. But, if any worked, it will be from the Touch 2. They appear to be identical except for the screen. Unfortunately, that would probably only use 800x600 pixels on the screen you have.

And I think the Aura Edition 2 is more likely to work than the Glo. It is the same resolution and it is in the same mark family as the Glo HD.

And you might get away with just writing the u-boot from the appropriate device. The firmware does detect the hardware, but it also reads the start of the SD card. etc/init.d/rc5 has:

if [ `dd if=/dev/mmcblk0 bs=512 skip=1024 count=1 | grep -c "HW CONFIG"` == 1 ]; then
	CPU=`ntx_hwconfig -s -p /dev/mmcblk0 CPU`
	PLATFORM=$CPU-ntx
	WIFI=`ntx_hwconfig -s -p /dev/mmcblk0 Wifi`
fi

Which, if I read it right, is reading near the start of the SD to get hardware information the hardware information. I can see "HW CONFIG" in the u-boot files. It might be enough to restore the u-boot image. Using the matching kernel might be needed as well, but I don't know.

And if it is using the hardware resolution from the u-boot file, it might be possible to change the resolution in the u-boot file for the Glo HD, and use that.

I have a Glo HD screen / shell for sale here: https://www.mobileread.com/forums/sh...d.php?t=291223

Only issue is USB data transfer. It actually perfectly usable as is with wifi syncing, but I bought a new reader anyway.
