I have s7 edge tmobile version. However, it seems like the band support is very limited. I know that sd820 should capable of supporting a lot of band, is it possible to unlock those band without rooting the phone? I travel a lot so would love to have as many band as possible.
It should already work almost anywhere in the world.
I'm going to the trip to China soon. Is it possible to use odin to flash the chinese version without root?

Wow its been a long time since I've been here! I see all of you are still busy!
... so basically, I'm going to buy an S4, but I'm not sure WHICH I should buy ... and I'm not sure where I should put this question since all the models are spread all over the place, but since I'm in Canada I thought this place would be a good start :laugh:
So basically, from what I've seen, the AT&T (i337) model is quite limited in out-the-box bands, and also has a locked bootloader. From what I've come up with, digging through information about all the models and Canadian carriers, is that the two best models for use in Canada seem to be the I337M and the T-Mobile M919 ... I really wanted a Samsung branded phone, but it seems if I get the I9505 I'll be missing out on a whole bunch of radio bands ... from what I've seen however, the unlocked I337M has no branding on it though ...
So basically what I've come up with is that both the T-Mobile M919 and the Canadian I337M both have unlocked bootloaders ... and they all run on the same GSM freq.
Someone please correct me if I'm wrong here, but, it looks to me like both the M919 and the I337M also share the same LTE bands, which are LTE 700MHz (Band 17) / 850MHz (Band 5) / 1900MHz (Band 2) / 2100MHz (Band 1) / AWS (Band 4) / 2600MHz (Band 7)
(my sources are http://www.samsung.com/us/mobile/cell-phones/SGH-M919ZKATMB-specs and http://www.pdaplaza.ca/products/Samsung-Galaxy-S4-SGH%2dI337M-16GB--Black-Mist,-Unlocked.html - I can't seem to find a reliable source for the LTE bands the I337M has ... on samsungs website it has a * Dependent on market and nobody seems to list straight up specs for the I337M ... actually it lists a completely different set of LTE bands which I'm pretty sure is wrong ... they list 1800 instead of 1700 and 800 instead of 700 which I know is incorrect for Rogers at least)
It looks to me, like the only real difference between the I337M and the M919 is that the M919 has a AWS (1700) 3G radio band, and the I337M has a 900mhz 3G radio band instead of the AWS band ... however, I ALSO have read that the AWS band on the I337M can be enabled (again, correct me if I'm wrong!)
If everything that I have read through is correct, it would seem to me like the I337M would be the 'ultimate' North American model, supporting more frequency bands than any other version (besides maybe the i9505 which lacks some bands I would probably need) ... unless its actually possible to somehow unlock all these bands on every version, and I just didn't get that deep into reading about hacking these phones yet ...
If I got something wrong here please let me know ... I would like to buy one soon and start flashing it
Thanks!
Lets put it an easy way, if I had the choice again, I would have not got the att galaxy s4 us version, I would have got the Canadian S4 i337m. My opinion only.
Or the Google Edition but its going to run you like 700-800$

If you're in Canada why not buy the i337m?
My i337M is completely unbranded once I installed a custom ROM and I managed to enable the AWS. Unlocking it has been a different story though :/
Well ... I just want the phone that has the most bands (its not really a cheap phone!), I'd like to get as much as I can for my money. I honestly have no idea if all the North American models have the same radio hardware or not, but at least on Samsungs website, they list the I337 (AT&T) with many less bands than the T-Mobile M919.
Funny enough, on Rogers website it lists the I337M only having 2100/2600 as the LTE bands, but on Bell/Telus it lits the I337M as having 700MHz/ 850MHz/1900MHz/2100MHz/AWS/2600MHz
It seems silly to me to actually manufacture different radio hardware for all the different North American models ... considering they almost all use the same bands except some exclude some, and there is one different one (3G AWS on M919 vs 900Mhz 3G on I337M)
I wouldn't get the AT&T US version ... as far as I know nobody has been able to unlock the bootloader. But apparently the M919 isn't locked.
I considered the Google Edition, but as someone said, it will run 700-800 (and you can't 'officially' get it in Canada)
Anyways, I found an unlocked I337M and I believe it is also unbranded ... so I bought it. If its not, I'll just flash it
I still am curious as to what they actually do with the radios though ... if they actually use different hardware or just lock the bands in the firmware (I'll take a guess the international I9505 actually has different hardware, though)
I think it would cost Samsung more to design different radio hardware for all the different North American providers (considering they almost all run the same/lots of overlapping bands) than just putting firmware locks?

I337m has all the radio bands, handles the lowest CPU voltages while still being stable... has an unlocked bootloader, and simply kicks butt.
Simple modem firmware flash fixes any location specific, and in my case, non-existant radio band issue.

Hi,everyone.
It may be a foolish question. But I'm not a pro (both in unlocking and English), and I'm not sure if there is a little possibility. Here's my question.
I have a redmi note LTE(Qualcomm) and I bought the chinese TD version by mistake, the network provider's frequency works on WCDMA/FDD- LTE.
And TD version supports GSM/ TD-SCDMA/TD- LTE but FDD ver supports GSM/ WCDMA/ FDD- LTE/ TD- LTE.
So Now I'm using GSM?
I found that both of the TD and FDD version are using same hardware, so I'm wondering if it's possible to unlock it?
Thank you!
Its not possible. Fdd and td have different hardware.
As Killerrade said you can't unlock a frequency, it needs specific hardware which it doesn't have. It's not like when carriers lock it.
@Killerrade @PeteSco
Ah how awful I can only use 2G…
Anyway, thank you guys for replying, at least I know it is impossible now.
Oh almost forgot, Happy New Year!
Hi,
It seems i have to buy the phone in Hong Kong to use the TDD LTE network from China mobile.
Does anybody know, what version of the S7 edge is sold in Hong Kong, is it Snapdragon or Exynos?
How can i check the difference before i buy the phone? Do They have different version numbers marked on the packaging?
Thanks!
Does anybody know, what version of the S7 edge is sold in Hong Kong, is it Snapdragon or Exynos? Snapdragon 820 (G9350)
How can i check the difference before i buy the phone? Just check the packaging
Do They have different version numbers marked on the packaging? Just G9350
Last year when I was still living in HK (and traveling between the US & Bangkok) I had the option to get the S6 Edge in any of the 3 locations. I chose the G9250 version simply for the wider LTE band coverage. It was a mistake. True that I could use it anywhere I traveled to, I failed to realize that in each place, with a local SIM, you'll have to be subscribed/registered (or whatever you call it) to LTE, otherwise you'll be connected to at most HSPA+ - rendering all those LTE bands a moot point. What I was deprived of, as a result, was the lack of development support. I was so itching to root the phone and ticker the hell out of it but decided just to leave it as stock - even until now.
1 year latter, along came the S7 and the exact same choice. This time it was easy and there was absolutely no doubt, I went with the international Exynos version - 935FD (silver) and never looked back. And yes, I rooted, TWRPed, Xposed, but still on stock ROM. I am having fun with my phone again
Do yourself a big favor and pass on the HK/Chinese 820 SD version - especially if you want root and beyond.

Yea, that why i asked the question, i will only buy the phone if i am able to root it.
My main problem is that i mostly stay in China and China mobile has TDD LTE, i don't know if the international version of the S7 edge can use LTE.
Does anyone know if the international version works with china mobile?
I don't think even the SD820 935F version can be rooted yet, you'll probably have to wait even longer for the 9350.
So now you have a dilemma: Get the rootable 935F/FD and not be compatible with China Mobile's LTE TDD bands 38, 39, 40, 41 - OR - Get the 9350 and not being able to root.
Remember that you can easily switch to "China Telecom or China Unicom" both of which uses LTE bands 1,3,5 and 3 respectively.
You can also still get 2G/2.5G on China Mobile with the 935F/FD

Hello,
I know this is a year old but I just came across this whilst researching for the S8. Just to add, I have the 935F from the UK and it works fine on 4G on China Mobile, not restricted to 2G/2.5G at all.
Just wondering if there are any radio LTE band issues using a G935f on tmobile usa. I know the g935t supports 4x4 MIMO as well as some specific Tmobile supported radio bands, wanted to know if using the Exynos G935f international version would have any problems or missing bands since I'd be primarily using Tmobile usa.

I never considered the WiFi calling I use that a lot. I guess now there is a decision to make....
Band 12 is not usable by default as it's used only for VOLTE and the 935F doesn't support T-mobile VOLTE out of the box. If you are rooted, you can download a CSC selection tool which adds VOLTE/Wifi calling/Band 12 support. Otherwise, the phone works great on T-mobile (I use a 930F rooted on t-mobile and have never lacked signal where my wife's Iphone 7 or 930T had a signal)
Can I ask a question to you nice folks who've replied... This "upgrade" from a T-Mobile branded G935T to international G935F is going to cost me about $100 usd give or take... The sole purpose is for real root access... Is it worth it? Or should I just wait and jump on a newer device?
The reviews of the S8 are great, but over all it seems more like a skin change than anything else (besides the screen of course)

Hi Friends,
Ever since I got hold of my Galaxy J5(J500F), which was imported from Saudi-Arabia to India, one thing bothers me a lot. That is, it didn't support the TDD-LTE band 40, whereas the Indian counterpart of SM-J500F does support it. Consequently, I'm unable to experience the true internet speed, while on one of the reputed Indian network operator servicing on LTE Band 40.
It's quite absurd that the both SM-J500F(Indian and Other regions) differ in terms of band capability, though they possess same hardware.
So, my humble request to great minds over here is, can you please tell me any tricks to enable the band40. Or, really is it possible to do so?
Thanks
