Is it possible to easily root the Altitude 4?

EDIT: I've looked into it and it's pretty much impossible. Unisoc, the chip maker, have prevented unlocking the bootloader, without which you cannot get root.

Just received an OTA FW update for the Altitude 4. I'd like to get the FW update image file off the phone for future use - is it possible to extract it somehow, or is it deleted after the update completes?

New Altitude 4 phone, cannot get sms to send from my XOX sim card even though the message centre number is correct. Voice call, data, no problem.
The XOX sim card works sending sms in my Huawei phone.
Is there any setting I need to change in Altitude 4? I tried various network modes via *#*#4636#*#*, still no success with sms.
