Hi All,
I bought an Oppo Find 7 x9077 which doesn't support the 1700 MHz band that is used by T-Mobile/ATT and most other major carriers in the US in order to get LTE.
My question is, is there a way to unlock the 1700 MHz band using software or firmware flash or is the limitation on the hardware side?
Thanks,
Colin
The 1700Mhz band is not supported by hardware on the X9077.
I see, thank you for the reply!

I just stumbled across this old thread.

Is the possibility of this true?? Has anyone tried to do work on the Radio ROM to bring in Quad band? I would pay to have 850 available for my phone.
Comments?
Has anyone tried an Athena radio on the Universal ( I presume yes, still looking through the forums ). And what about the HTC Sable? They both use the same CPU and the Sable in particular has comparable ROM sizes.
Quote from one of the links:
QUALCOMM's MSM6250 chipset solution helps enable worldwide roaming for
WCDMA (UMTS) terminals. The MSM6250 system solution supports dual-mode, quad-
band GSM transceiver operations [GSM 850, GSM 900, Digital Cellular System
(DCS) 1800, and GSM 1900] and WCDMA (UMTS) transmit operations for 800 MHz,
1900 MHz and 2100 MHz.
Shouldn't the Universal therefore be able to do 850 with a change to the radio ROM? Do the HTC Sable and Athena use the same chipset?
Can anyone help us?
It would be great to have a 850 band for my SPVm5000. Hope anybody can answer your question. Seems that since this phone was only released for europe and not USA the quadband was not open
Hi all-
just received my E970 yesterday, got it unlocked but still stock otherwise running on Rogers in Canada.
I've been reading a few threads here so far regarding rooting and the locked bootloader and some people seem to be implying that the S4 Pro chipset is an entirely software LTE radio. Does this mean that flashing a new firmware could change the LTE bands that a given phone supports?
ie: the AT&T E970 supports AWS 1700/2100 (Band 4) and 700mhz (Band 17) out of the box. Could this theoretically be loaded with software from the Rogers E971 with 2600mhz (Band 7) or the DoCoMo L-01E 2100mhz (Band 1) support? Obviously this would be baseband software not just a new OS ROM, but is it possible with the hardware or is this a non-editable function?
If anyone can provide insight or software I would be interested to test- as I am lacking the *special* 2600mhz support of the E971 here, and I do travel to HK and Japan occasionally, so support for 1800, 2100 and 2600mhz bands would be great, turning the Optimus G into a real worldphone even on LTE.

Thanks for the attitude.
I didn't say I expected to do this today, jackass. I asked if this will be technically possible as the models released appear to all have the same hardware specifications. Hopefully someone less smug, with more knowledge could provide real insight?
Sorry, should I be asking less technical, more brutally-important questions like when will Nova Launcher, or a different colour skin be available?

Just curious, where did you get your E970 from? I'm in Canada too and I would rather have the SD card slot than the extra 2600 mhz band.

That's a good question. It definitely sounds possible if you can flash the corresponding radio/modem and RIL.

I see that the T-Mobile LTE version is available in the US on the play store. It is significantly cheaper than in the UK.
I bought the v1 WiFi nexus 7 in the US and had no issues. If I buy the LTE version from the US can I assume that I can use it on a UK mobile network without issue? I presume both are gsm and there is no issue?
Thanks

Even GSM networks operate on different frequencies on different continents. LTE networks may have other frequencies than GSM networks.
I found a (german) comparisation list for LTE frequencies. For US, there are 700, 1700, 1900 and 2100 MHz listed; for UK there are 800, 1800 and 2600 MHz noted.
So, if you buy an US version, it will be useless in UK. Besides the useability, you may have to pay taxes on import, additional to p&p. Will it still be cheaper then?

For France, same frequencies than UK.
We will use someday 700 MHz also.
Some of us are waitin 4 an Euro LTE Nexus 7.
I found something about the Nexus 7 ... on http://www.google.com/nexus/7/ .
Scroll down until you see a link "Tech Specs". Open it and scroll a bit down; all GSM, UMTS and LTE frequencies are listed for different world areas.
The US and the EU version share most LTE frequency cpabilities, but the US version can operate on 700 and 750 MHz (which the EU device can't use) while the EU one can operate on 800 and 2600 MHz (which the US device can't use).
So it depends on your carrier's frequencies if you can operate an US device in UK or not.

My brother is over in the US next week and could therefore bring it back without P&P and most likely other charges.
In the UK the price is 320 GBP so the saving is around 100GBP with the currency conversion.
Currently I have my mobile with T-Mobile and a sim that I use in a mifi on Three. I am looking to move the Three mifi sim into the Nexus but I don't think that looks like it would work as it states they will use 800 and 1800. I presume that both frequencies are used?
The US device can't use the 800 MHz band, but the 1800. Maybe your carrier operates LTE at 1800, maybe not. Can't say that from here (Germany).
Going to take a chance. The US price for the LTE is cheaper than the WiFi only in the UK. Will advise how I get on

Same here Czech rep, 32 gb lte is the same price than 16 gb wifi here. But i need the 3G/4G internet can't risk it i must know
Aidenbree: this is exactly what i was thinking of doing too, so thanks for asking the question! I'm also on Three and would be really interested to hear how you get on. £100 saving is worth thinking about!
are they have different hardware ?
North America:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 700/750/850/1700/1800/1900/2100 MHZ (Bands: 1/2/3/4/5/13/17)
Europe:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 800/850/1700/1800/1900/2100/2600 MHz (Bands: 1/2/3/4/5/7/20)
or only radio software different?
if they just use different radio, it may work by change radio

Surprisingly, the radio software is the same, in fact everything software wise is identical between both devices, there is but a single firmware for both devices. I am not even sure if the US version can't technically use band 7 and vice/versa, has anyone tried to connect to a LTE network in the EU using a US LTE Nexus 7 ? Maybe those specs are just "limited" to comply with FCC/EU regulations/certifications (Paying for the CE certification for a specific frequency can be expensive)
If there is a difference then some flag must be set hardware wise to tell the radio what frequencies it can tune to.

omg
the radio is the same
seem they fix the band though hardware
any chance the software detect the mobile services provider to decide using which band
Hey guys,
I am in Malaysia and my phone operator uses 4G LTE on Band B7 2600. I can't find the proper list of bands for the Sprint version, can someone please clarify if I can use LTE or not?
Regards,
Zeekay.
Here you go: From the samsung web site:
http://www.samsung.com/us/mobile/cell-phones/SM-N910PZKESPR-specs
According to Samsung they do not support 2600 with this phone.
LTE: Band 25/26/41
800/1900 MHz (CDMA),
800/1900/2500 MHz (LTE),
850/900/1800/1900 MHz (GSM),
850/900/1900/2100 MHz (UMTS)
I don't know if there are hardware limitations that would prevent loading different firmware to enable band 7

People like me with unlocked sprint note 4's have been trying forever to unlock additional lte bands. But so far not possible! I have once found my phone on lte band 5, but don't know how it happened.
By default this phone only supports 25,26,41. Pic below.
I have found a hidden menu of lte bands but none work! Pic below.
Edit: @poit i didn't even see your post. Sorry, didn't mean to double answer!
Ho can you help me to understand if my mi 6 (sagit ) global can work with this Canadian carrier?
On the site of the carrier "Your phone must be compatible with LTE AWS (1700 MHz) or LTE 700 MHz bands, or UMTS/HSPA compatible on 850/1900 MHz bands. See your phone’s user guide for information about network compatibility."
Will It work?
Thank you
