i747m from Bell Canada - getting HSPA+ 1700mhz from Wind
Hey Guys, I am pretty new to the community and I do not know much about hacking and cracking stuff.... but I tried to read many posts and experimented with my S3 i747m by changing a few NV parameters and I can make it work with Wind (Canadian Carrier who uses 1700mhz freq.) I am not taking any credit for anything and giving full credit to who ever has worked or tried to work on it.
I am just trying to help a few people out who are working towards it.
here are my findings and what I did.
- I have not touched any NV flag items, just item 01877 and changed 04 to 06.
- Initially it does not work, but after I restart my phone. I go to network operators and manually select my carrier and it connects.(I am getting HSPA+ connection)
- If I restart my phone second time, it does not work anymore and I need to change item 01877 to 06 again.
Possible reasons why it is getting changed to 04 again may be because of check sum, as we are just changing just 1 value. If any checksum is attached with it than we need to update checksum as well. so upon restart checksum of NV parameters is not matched and it is reloading all defaults. Expert may think on this as well.
It is good enough for me rite now, it is just like tethered jail break for Iphone. I am taking care that my phone always remain ON.
I dont know if all are experts here, and can understand all instructions, but I found it very difficult to follow instructions given in this forum and other forums. If someone who want to enable it on their phone and do not know how to do it, I would like to help them out by making a simple DIV. believe me, it is very easy, easier than rooting, anyone will be able to do it on their own. just put message below and I would help them out.
Again, thanks for help everyone
