Question: the new OTA also removed the option to SIM unlock for free. Will flashing this modem do that too?

This flashes the modem.bin file... which writes to a separate DevBlock (partition).. won't write to /system, /data, /boot, /cache. I flashed this MA4 modem over my LK7 modem (while running CleanROM v4.5).. works fantastic. I'd recommend backing up your current modem partition (in on TWRP), then flash this... if it doesn't workout better for you, restore your current modem.

I did exactly this last night, and everything went fine. Still experiencing Wifi dropout though. Only solution is to turn off Wifi PSM via the *#0011# menu...but I have to reapply with every reboot. Was hoping the issue would be solved with new modem, but at least I'm getting better wifi upload speeds when it stays connected.

I just installed the newest AT&T modem. After picking "reboot system" in TWRP, I noticed a little flakiness on 4G and WiFi data. Powering the phone down completely and restarting seems to have gotten rid of it. Just posting in case anyone else sees similar stuff.

Right now I am on stock AT&T Note 2 phone using it on T-mobile, the phone is rooted though.

Is there a way to backup my existing modem before flashing this one? I am using CWM.

Thanks

    Ran a Q&D modem SpeedTest comparison tonight between LK7 and MA4.... all within same hour...all on the same local server. Results attached. Basically, the HSPA:11 speeds were about the same (slightly improved on MA4)... and I noticed a big improvement on upload speeds over WiFi. Take it for what it's worth... just another data point for those interested.

    Thank you for pointing that out to me. Didn't know that at all. I just try to help out where I can.





    Great point. Also, you always want to ask before you post a mirror link in someone else's thread. Just for future reference. Thanks.

    Got it & you're absolutely right. And the funny thing is I said that to my self if I should ask him first since I had downloaded already.
    Thanks for letting me know. Will ask from now on with a PM!! :)
