I just "fixed" my phone yesterday following the instructions that were on this thread. I dont think Wind is going to change this on their phones anytime soon unless their whole network starts supporting LTE. The instructions below fixed the problem rather easily but wiped all the data from my phone.
Prior to doing this I used Samsung Smartswitch to back up my phone.
Power off device, take out sim and power on. Ignore the no Sim message and then boot in safe mode as below
How to boot in safemode:
Power off phone, let stand for 1 minute. Turn on the phone by pressing Power + Volume Down, once the screen lights up, you can release the Power button but keep holding Volume Down until you get to lockscreen.
If succesful, you should see a Safe Mode stamp on the bottom left. Once that's done, try going into settings and see if the LTE is available in network mode. If not, try manually selecting Rogers as a network operator.
If all fails, boot back up normally and try changing CSC to Rogers. First get your IMEI and write it down by pressing *#06#, then press *#272*YOUR IMEI HERE# and click RWC and click Install. This will factory reset your phone so make sure to backup before.
Forgot to mention to put your sim back in before booting in safemode
I would forget about safe mode. It didn't work for me. These are the steps I took
1. Backup phone with Samsung Switch or in your case maybe Samsung Kies
2. Get your IMEI and write it down by pressing *#06#
3. then press *#272*YOUR IMEI HERE# and click RWC and click Install
4. Turn on phone and restore from Samsung Switch
So far so good with my galaxy s6 edge
Thanks. Sounds pretty good. Doing my backup now. I am using SmartSwich. (KIES was too old for my model).
Forgive my ignorance, but do I assume you type in the #272 sequence from the Phone keypad??? and then it will produce a "RWC" prompt??
Yes.. the #272 followed by your IMEI as mentioned before right from your keypad.. you will see a screen that will allow you to select RWC..
I know my IEMI, and double checked it with *#06# . All good. It also displays /08 at the end. Is that relevant?
But when I enter * # 2 7 2 * followed by my IMEI and # , I get nothing .... no prompts.
Do I also need to enter the "08" at the end of my IMEI?
No it sounds like you did it right... might be your android version. i am on 5.1.1. Maybe you need to update. Not sure I can help you out much further, sorry.
