Hi Guys
I have a poblem that regards 4g plus connection, I live in a city almost fully covered by 4g plus but I have never seen on my mi5 4g plus. I'm alway on max strenght 4g signal. I know that the lack of 800Mhz band might cause a drop of signal but I know that 4g plus can be obtained also by the sum of 1800 mhz and 2600 mhz bands. Do you know if Miui can notify the 4g plus?
Thanks a lot
I've see the 4G+ symbol appear intermittently on the status bar whilst travelling on the train. So I know for a fact that it does support it. I'm running MIUI 7.3.4.0.

Hello have looking for a patch for long and no sucess. Had a few times this
Radio 1.09.25.23
on it and got instead a "E" also a "G" Signal for some mInutes. What is this ? Is this a evidence the HArdware is able to get the signal or ?
Someone how can explain this
I think G maybe for GPRS, E for EDGE
to bad
And I was hoping there is in the US a little hope to get service with this phone (other than GSM)
Unfortunately you cant get 3G service in the USA. Couple of months ago I had my Eu Diamond with the AT&T, but no 3G service. Hardware doesn't support US 3G frequencies. Sorry...
That is why I use an iPhone now
You are right. US 3G (UMTS) freuquencies are 850/1900 MHz (AT&T Mobility) or 1700 MHz (T-Mobile). In nearly all other countries world wide its 2100 MHz.
First, I'm a flashing newbie, and still have the stock ROM and Radio flashed on my Touch Pro 2.
TMOBILE has now updated(via some secret behind the scenes update) their Touch Pro 2 owners to "4G" coverage in the Detroit metro area. I would like flash to some of the ROMS offered but I'm not sure if after doing so will I continue to receive TMOBILE'S 4G coverage. I understand that "radio" flashing is separate from Rom flashing but is anyone sure that just flashing the ROM would not effect the TMOBILE 4G update.
Any help or insight is greatly appreciated.
Thanks
Does the TP2 hardware even support 4G? That's not something you can just "upgrade". Are you sure that they're not just offering more bandwidth via HDSPA? If that's the case, then what ROM you're using will have no effect on that seeing as nearly all custom ROMs have it on by default.

Got a screenshot of your TP2 showing 4G?
from my understanding, only the touch pro 2 from europe and japan have the 4g hardware, usa only 3g hardware, thats why i bought mine from taiwan so when 4g comes out, im well equipped!!!

what they are actually doing is claiming their 3g network as 4g. its hspa. they took a card from verizon that considered their 2g network to be 3g. "you mean, alot of our 3g network is slower than atts 2g? and the only bits that are fast enough to keep up have less coverage than their 3g and is still slower? nonsense! i choose not to believe!"
T-mobile is marketing the same network even when they say 3G or 4G because it's all just upgrades, the appropriate term should be "3.5G". all of their sales reps i've encountered don't know anything about their network or their devices.
a week before the G2 came out, one of the reps tried to tell me that it was sporting a "dual-core processor". i laughed and corrected him without missing a beat. just watch their commercials...it's sad to see someone advertise 4G when it's just "3.5G".

Actually, it's HSPA+, not HSPA, T-Mobile & Sprint are advertising as 4G, which is faster & only a select few devices support the new HSPA+ speeds. So, it's more like 3.75G. HSPA+ provides HSPA data rates up to 56 Mbit/s down and 22 Mbit/s up. Future revisions of HSPA+ support up to 168 Mbit/s using multiple carriers. Regular HSPA maxes out @ 14 Mbit/s. The TP2 & most of HTC's 3G/HSPA(+) devices only support 7.2 Mbit/s down, 2 Mbit/s up. So, to answer the OP ?, If the network in that area was slower than 7.2 Mbit/s down before the upgrade, you will see an increase, but it'd be maxed out at 7.2 Mbit/s due to device limitations. As this is a Hardware issue, ROM doesn't matter other than the fact the lighter ROM's runs faster & therefore can get higher speeds because of the extra free RAM/Resources. Whereas, heavy, more feature rich ROM will tax the device more & therefore the CPU/RAM/Etc. won't be able to attain max bandwidth. It's like having a 30 Mbit Cable/DSL connection on a Pentium 3 PC. It'd never get the max speed as the system is just too slow to take advantage of it.
So basically, their advertising maybe false, it is used to explain a faster network & used to simplify which devices support this new speed. Most consumers wouldn't understand all this. So instead of dealing with, "why doesn't my 3G phone get full speed? *cry*" from customers not understanding their device has a limited bandwidth. Think of it like the days of dial-up modems. ISP A has a 56K network, but User B has a 28K Modem, so User B only gets 28K speeds.
"A 4G system is expected to provide a comprehensive and secure all-IP based solution where facilities such as ultra-broadband (giga-bit speed such as 1000+ Mbit/s) Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users."

So it goes something like this;
2G -> EDGE (2.5G) -> 3G -> HSPA (3.5G) -> HSPA+ (3.75G?) -> 4G (?)
Also keep in mind it's measured in bits per second, not bytes. There's 8 bits per byte. So 8Mbit/s = 1 MB. Also some service providers cheat by counting it as 10 bits per byte. (b=bit/B=Byte)
EDIT: Interesting side note, according to gsmarena.com, the G2 & MyTouch 4G only supports HSPA 14.4 Mbit/s down & 5.76 Mbit/s up (T-Mobile's network is 21 Mbit/s according to reports) & the Evo 4G only supports Rev. A, up to 3.1 Mbit/s.
I have been posting in the optimus forum for help. I just noticed last night in a topic yesterday that LG Thrill and LG Optimus 3D are the same, except Thrill is 4G.
My phone is called LG Optimus 3D p925g, it's from rogers and I got it October 2011. It's 4G.
is mine the same as Thrill?
What happens if I use LG Optimus 3D 3G roms on a 4G?
Nothing happens. It's the same.
ok Thrill must be an american brand name or something.
when I flashed cyanogen mod ROM I remember seeing my 4G turn into 3G icon. Does it actually change to 3G or no?
also is this forum more active for help? I wonder why they have 2 forums if 4G/3G is only difference.
It's not even real 4G though. So it's all good.
The other difference is that the basebands are different.
One is international, the other is not.

not real 4G? What are you talking about.
I don't know what basebands are so okay.
Well if it says 4G, you're getting almost the same speed as 4G. There's a detailed explanation somewhere. I gotta find it.
Its 3.5g the way i have it my p925g. Always says 4g i dont know why even if i dont havr 4g speeds
4G implies 4th generation technology and standards. Ignoring the fact our '4G' is actually HSDPA+ (which is pretty much what 3G was supposed to be, but they did the same marketing BS with 3G)... we are nowhere close to the simple basic, no BS 4G standards of 100MBPS+ data speeds, with true multi-tower connections.
As well, all 4G means for most GSM carriers is that the phone has the HSPDA+ protocol enabled, and the towers in that region have the same... which is a simple software upgrade. You could be on a 500Kb connection, but they call it 4G simply because it has HSPDA+ protocol delivering those 2G speeds with a 3G technology.
The closest thing to true 4G on the market is LTE, which is totally new radio technology and tower technology, not simply a software upgrade that increases speedo's top speed from 5Mbps to 45Mbps, even though the motor is still only capable of 2Mbps.
The motor, btw, is the tower backhaul, and that is the real bottleneck in all of this and is what will determine your actual speeds. As it stands, there isn't enough hard line bandwidth out there to give true 4G speeds, and likely will be 5+ years before there is.
By then we will be on "6G" and some will still be running sub 1Mbps connections despite the hype.
ya we got lte phones hear now system isnt even up but rogers is claming its going to be 150mbps downloads
The Only difference
Thrill 4G Networks GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1900 / 2100
Optimus 3D networks GSM 850 / 900 / 1800 / 1900
HSDPA 900 / 1900 / 2100
HSDPA 850 / 1700 / 2100
maybe it is
HSDPA 900 / 1900 / 2100
OR
HSDPA 850 / 1700 / 2100
because 1700 / 2100 mean AWS and i don't think this phone (p925g) is aws
don't know what to do.
Hi,
someone offer me a Lg p925G from rogers which is unlocked. the problem: I live in france, when I put a french sim in the phone didn't find no network at all even a simple GSM; I tried to register manually to my network (the phone find it) but say that 's impossible to connect it. The phone is under the last V20C rom from rogers.
My question is simple: is that a hardware problem with the frequencies? or just a problem from the rom?
thanks a lot!
Hi all
I bought the Xperia Z C6603 in UK will it get 3g or 4g or let in NY, USA?
i been reading in the blogs that it wont support you will only get GPRS or EDGE based on this t-mobile thread http://support.t-mobile.com/thread/40671?start=0&tstart=0
but can the Devs do something to make it work on 3g/4g with current hardware in the phone? or should I return and buy the phone when it comes in the USA?
all help is appreciated
I'm not sure about 3g, but I've heard that the 4g bands that the phone uses are different then being used in the States. So that won't work.

As I posted here

The reason is, according to T mobile
Depending on where a tower is at in the 4G life cycle, theoretical maximum download speeds range from 21 Mbps – 42 Mbps.
T-Mobile's HSPA+ network operates on the same band as our 3G network, Band IV, which uses 1700 MHz and 2100 MHz frequencies to transmit voice and data services. The 1700 MHz frequency sends information to cell sites and the 2100 MHz frequency receives information.
As with our 3G network, both 1700 MHz frequency and 2100 MHz frequency are required for a device to function. If a device only has one of these frequencies, it cannot use T-Mobile’s 3G and 4G networks.
T-Mobile is switching some 1900 MHz frequency from EDGE to HSPA+. This will allow devices that work on 1900 MHz, such as AT&T devices, to use our 4G network.
and yes,the Xperia z uses UMTS HSPA+ Bands 1, 3, 5, 8 which are
1 for 2100, 3 for 1800, 5 for 850 and 8 for 900
the HSDPA in T mobile are in the bands 1700 and 2100, just like the 3G, and the Xperia Z model c6603 uses bands 850/900/1700 only!!! the C6602 model uses the same bands plus /1900/2100 so, if you miss one band in T mobile you will never have the HSDPA speed, no matter the firmware,because is hardware
This info is according to Sony Official Page www.sonymobile.com, so as you can see you are missing one band, the 1700
Resuming, is hardware issue, and I dont think that the developers will be able to get 4G speeds or even HSDPA if the chip required is missing iin the c6603
c6602 is the only choice
Im currently have c6602 on tmobile and I can get h+ speed on it I did order c6603 and only get EDGE. You will have to set APN manually se the phone canlog into the network. Or u will have to get ZL since I heard that Xperia Z wont be distributed through any US carriers.
I'm using potter xt1686 Indian variant. I started to use this app called NSG because in my house Jio range was poor. So I fixed the band of LTE to enable carrier aggregation.
But the issue is that I used to use Idea sim in 2nd slot. Before using the NSG app I used to get 8-10 Mbps speed in 4g which dropped after I locked the bands.
If I clear the forcings then very rarely I get the usual 8-10 Mbps speed. Generally it stays at 1.5- 2 Mbps.
Can you guys suggest how to revert all the changes made by NSG so that I can go back to the original state? Uninstalling and rebooting the phone doesn't work.
Try enabling 850 1800 and 2300 band in band locking
