i9205 4G LTE on T-mobile - Samsung Galaxy Mega

Is it possible to port over a modem to get 4G LTE on T-mobile for the i9205? HSPA+ is fast enough but service is kind of spotty in the Orlando area. Does anybody know if this is possible or is it a hardware issue that software cannot fix?

I have tried with no luck with odin it has a secure boot error. need some one with a rooted telus i527m to make a dump of there mmcblk0p1 partition.. to do that thay need to use terminal program on there phone.
su
cd mnt/sdcard/
dd if=/dev/block/mmcblk0p1 of=backup-NON-HLOS.bin
that will make a back up on there sd card. then when we get that backup file from them then we could install on our i9205 by placing the file in the root of the phones internal storage. and with terminal type
su
cd mnt/sdcard/
dd if=NON-HLOS.bin of=/dev/block/mmcblk0p1
Try at own risk

is there anyone out there willing to try this? I'm sure this would be beneficial to all of us. I will make a pledge of $20 if we can make this work. Lets get this rolling.

Software drivers (modem) cannot change hardware specifications.
The AT&T mega is full 4GLTE and that's the only way you are going to get it!
It works on t-mob as well.

I wonder if this is just like my Note then. I'm using the AT&T Note on T-Mobile and getting LTE. All I had to do was unlock it, inset T-Mobile sim and then change the APN settings.

No root, no custom recovery, no custom ROM, yet.
It will come and then the lid will be off!
I think this will be seen as one of the great smartphones!

Gotcha. I think I just realized there are two different versions. I'm guessing they have all this stuff for the first one already. That's what was throwing me off lol.

The i9205 is 4g lte, but it is the european version. Can anyone verify if we can get it to work on tmobile lte if we can port over the i527 modem?

It's my understanding that the LTE frequencies are different so porting a modem would make no difference at all.

will porting a modem over at least help with reception issues? A lot of time my phone gets on edge, and if I keep it on wcdma only I loose signal sometimes. Has anybody had success porting over a modem to the i9205? If so what kind of results did you guys get?

if you're wanting to get LTE on T-Mobile carrier... then the Mega you want is the US AT&T version....SGH-I527
good luck

Yes but, different bands. The I527 (AT&T model) can access the T-mobile 4GLTE bands

thanks. do you know if you get the At&t mega and it has a bad Esn, will it still work on tmobile? the ebay seller claims it will. it seems it would.

I Purchased a I527m (plus and extra 50 bucks for SIM unlock code) from a (Canadian carrier) and successfully rooted with TWRP, and flashed it with a stock Canadian firmware ROM to use with a T-Moble SIM card here in the US. After a few APN changes I get T-Mobile 4g LTE, HSPA+ and very fast DL/UL speeds. I do live in a re-framed area so I am sure that adds o the increased performance. Below are my average speeds. Hope this helps.
