Huawei Y538 no signal after firmware update

[arat1]

Couple days ago I unlocked this phone using dc-unlocker, and everything was fine, but today after I installed firmware update phone is showing (no signal,emergency calls only).
Dc-unlocker is showing that phone is still unlocked, but after trying to find networks manually, all discovered networks have forbidden note with them.
The old firmware had B138 ending, new has B150.

If software shows that it is not locked then problem is obviously new firmware that you applied for device, you should start looking for differences there first as we do not use devices ourselves and won't be able to add valuable information to such problem.

Is there a way to install old firmware? It was y538c237b138 but I cannot find it anywhere to download.

Sorry but we won't be able to advise on flashing it, we do not have firmware file for phones as well.

OK, I figured it out, the new firmware disabled roaming, because when I inserted local sim card it gets signal. Can you software enable roaming on this phone ?

No, unfortunately our software does not have such service.
