MODEM][FLASHABLE] MK5 Virgin Mobile/Boost Modem

Please make sure you thank @CNexus the next time you see him, because without him it would be much later before this got out. The guy’s a genius, and a huge help whenever I get stuck. So thanks!

Just a notice: Modems do not contain Knox, this is no different. It is safe to flash, so please don’t ask if it will install Knox. Now you know!

is there a specific set of APNs that are best utilized by this modem?

I get improved reception for calls and texts in my house (which has horrible service) however MMS is non-existent and data takes a while to connect.

I'm a VM user btw

This is a completely stock modem, and I have not messed with any apn settings. Have you tried other modems? Maybe MK3, MG2, MD7, or heck, I've even heard some guys having success with LJ7. And when you first flashed, did you run the reset activation by running ##72786# on your dialer? And updating prl and profile? Just spit-balling here...hope something sticks

Thanks. This modem works very well for me. The MK3 was very slow to connect, would drop connections and was slow. The MK5 connects very quickly, is stable and is quite fast even on 3G.

You should have 4g LTE if you have it in your area. Did you check to see if there is lte coverage for your carrier? It is different from 4g, so it might be worth checking. Additionally, if that's not it, have you tried reactivating everything after initial flash? Try running ##72786# from your dialer, and let it run through activation. That might help. I remember when I first flashed MK5 it took forever and several activations to finally get 4g

I can flash this over MK3 without worring about hard brick right?
Correct. Modems have nothing to do with bootloaders, even though they use the same letter/number system for naming. Anybody on Sprint or Virgin Mobile or Boost can use the modems from all previous builds for any of these phones interchangeably as well--both MG2 and MK5 from VM/Boost have been reported to work well on Sprint phones, and I can confirm personally that the Sprint modems like MK3 and MD4 run fine on Virgin.
