How did you lock it? There are a number of different locks, some of which your service provider will unlock. I have puk locked my phone before, a simple call to my provider fixed the issue.

Hi, I'm using win 7/32 and I did not need usb drivers. We restarted the windows, in F8 I turned off checking the drivers' signatures and then started the windows. On the phone I enabled the developer options and the usb troubleshooter. Then I plugged the usb cable (on) to the computer. It will start downloading and installing the drivers. You have to run all the options for connecting the phone to the computer (usb configuration), from simple loading to MTP, PTP and MIDI. When all the drivers have been installed, restart the computer and turn off the phone. At me, (Cubot x 18), I have not removed any battery, neither sims nor microsd. Just with the phone off. When you restart your computer, start the sp flash tool, choose MT6737T_Android_scatter for what you need, choose the option and activate it, and finally plug the phone off to your computer. From now on, everything has to go ... That's the method I use. I was frankly amazed that she was running without a battery in the phone; and all the way to him, just stopped.

Hi just got my phone and the mobile data is disconnected. I cannot turn it on and when I try to go into phone settings and try and change the radio band it crashes the application. The option to enable mobile data is there but has no effect. Anyone know of a fix or maybe how to download a new modem? Tyia
Maybe this ...

Hello, I think you need to set a new APN. To do this, you must go into Settings-Wireless & networks-More-Cellular networks-Access Point Names. At the top of the bar you will have to press "+" and you will need to configure the new APN according to the mobile phone operator from which you have the SIM card you are using. Once configured, you'll need to save and check it as an asset, the one that your phone will use. That's all. And there would be something else. At my side, I can not catch 4G, it gives me connection error. So I set it on 3G, from -preferred network type. Hope to help.

Thanks mate. The correct apn had been set and it shows 4g connection at the top but simply refuses to connect to mobile data. It all says its switched on etc. When I type +*+*4636*+*+ into dialer screen to bring up phone settings it is there that it says mobile data disconnected and it simply will not switch on.
I've also factory reset the phone and it won't connect to mobile data then either. When I try to change the radio band it crashes.

Wi-fi going? Perhaps there is something on / off in your phone that limits your access to your mobile data network (billing cycle, data usage, roaming, or anything like that). Frankly, my knowledge is limited, I do not know what else it could be. If wi-fi works, try updating it, you may be lucky.

Thanks mate. Nah me neither. WiFi does work but no joy with mobile. There's no update available and a factory reset never cleared it. I think the issue lies with the radio band. It simply crashes the application whenever I try to access it.
Not receiving incoming calls when in VoLTE
Since my carrier is activating VoLTE through its network
I cannot receive incoming calls. If my phone receives only the 4G signal (without VoLTE) the phone works perfectly. I tried another sim card of the same carrier...same issue! If I put on the phone a sim card from another carrier it works fine, but I think this carrier is not using VoLTE yet. Using the *#*#4636#*#* menu I switched off "provisioning VoLTE" option...but after a few seconds it turns on again automatically. I do not know yet if the problem is linked to my phone, carrier or a problem on Android. Does anybody can help me? Thanks in advance
PS: my phone is running native Android 7.0 and it is updated with the latest firmware version
Try a drastic solution. Reflash your phone. The problems are with MTK firmware structures, MTK firmwares usually results in lost IMEI or NVRAM issues.
I am a fan of anything MTK phablets, tablets, phones and owned mostly Lenovos about 7 devices, all rooted with TWRP. My advise is to reflash the phone (since we already have the firmware), if it doesnt work the first time after reflash , you probably need to reflash a few more time and you will find that after every reflash there will be random functions and apps broken (after the next reflash the functions and apps are OK but others broken) until you will have all 100% OK. That is my experience with MTK SoC.
Good Morning!
Can you tell me if this procedure works on the new model, the P20? Uses Oreo 8.0.0 with Kernel 3.18.60 ...
Thank you very much
Me too

Hello guys,
I've the same problem with my X18. Everything works fine. My SIM is active and registered and in the notification bar there is a 4G-icon, I can make some calls, receive SMS and so on. But if I use mobile data, the connection will be interruped after few minutes and in the settings dialog the SIM card is disabled.
Reboot, changing SIM slot takes no effectes. This error is reproduceable.
The device has 3 APN-Settings. Is there any oppurtunity to delete these settings, so that I can receive new APN from my provider or to define it manually?
Best regards
Dan
