Q: In some Samsung and HTC phones, for example, the phone is with a Qualcomm baseband, but NSG testing mode cannot be achieved, why? This happens in Samsung i9505, i9506, G920V, N900x, HTC One, HTC M8, etc, most of them come with an android 5.0.

A: in some Samsung, HTC and Sony phones, the manufacturer removed NSG needed drivers for diagnostic interface. So NSG cannot detect it as a testing phone. There are some possible ways to fix this problem.

Firstly you can upgrade or downgrade OS provided by your phone supplier. In Samsumg i9505, SCH-i545 4.x or 6.0 is ok for testing, but with 5.0, it’s not OK.

Besides, for Samsung phones, user can try some other ways. In stock recovery mode, and enable CP logging option and testing screen mode will be achieved. It’s from some European users. Thanks for their advices.

There’s another way. Some 3rd parties are providing ROM for Samsung, HTC, and Sony and etc. user can find the correspondent ROM to your own cell phone. Some NSG users shared us with that information. These organizations are:

Cyanogenmod (http://www.cyanogenmod.org/),

AICP (Android Ice Cold Project, http://www.aicp-rom.com/),

Xiaomi MIUI (www.miui.com).

Q: Can you changed the band capacities of my cell phone. My cell phones are from other countries and the band capabilities are not so good, and I want more band support. Could NSG do that?

A: NSG cannot provide this kind of feature and we need to write some NV items to change the band capabilities. But it’s different among different phones. So it’s very dangerous and once failed, you will lose all of the band capabilities of certain radio technology. And it’s very difficult to recover.

Q: In some countries, dual SIM card is widely used. The NSG UI is switching time to time. Is it a bug? When will NSG support to Dual SIM?

A: Dual SIM is supported since 1.3 before that, not supported.

Q: How to root an android phone in an easy way?

A: In some android 4.x devices, it’s very easy to root. User can find some apps online (king root, rootmaster, 360 root and etc) and you can root device easily. But with 5.0 or above, it’s not easy. Some phones needed to unlock bootloader. For Samsung devices, you can root it with ODIN tools and unlock bootloader with a CMROM Service App. If you are not so professional at rooting devices, we would like you to buy some popular phones, such as XIAOMI, OnePlus, LeTV, Samsung and etc. These devices are very easy to root because the manufacturer provides the way to root their devices. After that, remember to use SuperSU to grant super user to the APP.

Q: I cannot get the configurations. But internet connections are OK, the app exit.

A: NSG needs to download some online configurations. This downloading process is through a security internet connections. To make sure you can download, you must be sure two things. First is setting the time of the phone to the current time. Second is to make sure that you don’t block the certificate for our website. You can try this https://m.qtrun.com. Just visit this URL. If you can visit, second step is ok. If these 2 steps are done and you still cannot download the configurations, you have to contact us with email. Thanks for your corporations.

Q: How can I move the license to a new phone, or sometime the phone is lost, can I resume the license?

A:  Yes, just keep the information in your purchase screen, which includes your serviceID, InstallationID and we will move your old license to the new testing models. Send us your information and we will do it for you.
