Need answer

Got a new htc m8 motherboard (from swap). Checked the cid version with an app and it came out as AT&T, but into bootloader i see "s-off" and cid-11111111, which i guess is developer edition, as the owner never s-off it manually. So which version it is? And as i got s-off, can i convert to international version/gpe?

Such "CID getter" apps are not always reliable. Either just boot to bootloader, or (if you know how) do fastboot getvar all, and you can easily see the (actual) CID.
but into bootloader i see "s-off" and cid-11111111, which i guess is developer edition, as the owner never s-off it manually.
No, CID is for Dev Ed is not 1111111. Rather, it is called SuperCID.
CID for Dev Ed is BS_US001 or BS_US002.
Dev Editions does not usually mean s-off. While it is possible (but very rare) to see HTC devices from factory with s-off, I have never seen them from the factory with SuperCID. Therefore, the device was almost certainly user modified. If not by the owner you swapped with, then by a previous owner or vendor.
So which version it is?
Not certain. As mentioned above, you need to tell us the actual CID, not from CID app (which are not always reliable).
And as i got s-off, can i convert to international version/gpe?
Most likely. But again, need the obtain CID by the proper method. Really, fastboot getvar is the best way, since then we can also check the MID and other details. If you post fastboot getvar output, be sure to delete IMEI and serial number before posting. .

Remember that time I told you to be sure to delete IMEI and serial number before posting getvar output?

Be sure to read, understand, and follow instructions carefully. Or messing with this device will not end well for you.

Based on the getvar data, the device is AT&T or Dev Edition. Both version share common product name m8_ul_ca as well as same MID 0P6B12000.

CID is SuperCID 1111111. Probably modified by some previous owner or 3rd party vendor.

Current firmware is 6.12.1540.4, which is Dev Edition. So the device either started life as the Dev Edition, or was an ATT model and "converted" to Dev Edition. If the back plate has the AT&T logo, then it (obviously) started life as AT&T version M8. Lack of AT&T logo on the backplate is not conclusive. It can still be AT&T (but had back cover replaced to remove the logo) or it may have been original Dev Ed from the factory.

Either way, it doesn't matter much. It can be "converted" to unbranded "401" international version or GPE. But keep in mind, that converting by RUU will also change the specific bands supported. May or may not be what you want. GPE in particular, does not have very broad band support.

Whether "converting" to another version is the right thing to do for you; depends on what you are looking to do, the specific bands used by your local carrier, etc.
