On the 15 inch Purism Laptops. Have not tried 13 inch.

Should i wait for a new coreboot/oem install or should i use the older version that i know would work?

Is it possible to flash the older coreboot onto a laptop that had the new coreboot flashed on already?

@mak @kakaroto can we test this somehow? Also @ah_purism can you attach images as well and check if you have access to logs?

how would i check the access logs

press back or escape button and you should have an option to access the shell/logs

upload failure

I tried installing using the same OEM installation. i get this error. I will send through my whatsapp account. It might be the download may be corrupted?

@ah_purism From the logs Zlatan sent me it looks like this is indeed the case. The SquashFS filesystem on the source disk is damaged. This can happen because of a defective download, or because your USB stick is at the end of its life.
Can you download the ISO image again, verify its checksum and then try it maybe with one other USB stick, to rule out defective hardware?

its the usb(s) that are having the issues loading purism OEM install. Problem Resolved with new USBs.
