Hello community what a great help can someone found from here ... so here we go ...
My problem is i turn on my mobile data to get 4g then stay's for a while but then it dissapears and then drops down to E and it wont change from there ... and in order to bring back the 4G i need to restart the phone or to shut it down and turn it on again ...
do i need to change my rom or i need to change / flash my radio ? rom is the stock rom i think i got on it ( 5.0.1 sense 6.0 )
see attachment
thx in advance
What is your location and carrier, and what bands do they use for 3G and LTE?

That doesn't tell me what band MTN uses for LTE (4G). You should call your carrier and ask them (and confirm they use 2100 MHz for 3G).

I take this to mean 900 and 1800 MHz (bands 8 and 3), rather than the way you have it typed "from 900 - 1800" which makes it sound like a range, which doesn't make any sense.
I also don't think this information is correct (as I've interpreted it), as far as I can tell, 1800 MHz (Band 3) is not used for 3G anywhere in the world: https://en.wikipedia.org/wiki/UMTS_frequency_bands#Deployments_by_region_.28UMTS-FDD.29
You need to be sure of exactly what band is used for each (2G, 3G, LTE), before we can proceed:
What band (or bands) used for 2G?
What band (or bands) used for 3G?
What band (or bands) used for LTE?
It pretty rare that the same exact band or bands are used for all 3 (2G, 3G and LTE) by one carrier, so the answer is expected to be different for each, and should be asked, and answered on an individual basis.
Reason we need to be so specific here, is that there is no radio for this phone that supports Bands 3 and 8 across 2G, 3G and LTE (and in fact, no radio that supports Band 3 for 3G).
Once you've properly determined what bands are needed, and identified what M8 version supports those bands, the way to proceed would be:
1) S-off by sunshine
Note: If sunshine temp root doesn't work, you may need to unlock bootloader and root, before you can s-off with sunshin
2) Possibly need to change phone's CID and/or MID
3) Flash the firmware or RUU which contains the desired radio baseband
Even then, its not guaranteed that LTE will work. I've see a good number of folks on these forums that properly flashed the radio baseband (or converted to another version by RUU) that supports the desired bands, but still didn't get LTE service. I don't know why this happens, and have never seen a solution. But its a distinct possibility.
But at a minimum, you should be able to get 3G working on your carrier. Which alone may make the above process worthwhile.

Hello and thank you very much for you time i will go again and ask for more direct info's about bands individual
i have found back up of a radio and i flash my phone and now i do get LTE singnal's but hardly get H and 3G when no 4G detected it goes to E ... well ....
now i got another problem maybe i shou ld post a new thread ... my gestures won't work suddenly ( omg !! ) i calibrate and uncheck and reboot and check them from setting's over and over nothing worked

You need to specify exactly what you flashed, and where you got it from, for this info be worthwhile in any way.
Also, still need to know what bands your carrier is using, in order to determine what radio to flash.
Why you are flashing radios, without knowing if its the right one (supports your carrier's bands)? This is really careless and reckless.
Is the phone s-off? That is normally the only way you can flash radios manually (aside from a signed OTA, RUU, firmware.zip). And flashing things with s-off is a great way to brick the phone, if you flash the wrong thing (and it doesn't sound like you know well enough to know right vs. wrong).

Anyone knows is this phone (USA T-Mobile) works in Europe??
It 100% works on GSM and EDGE (2G and 2.5G)
As for 3G, I assume it may work on the 2100 band in Europe (does anyone know enough to clarify on that). However your operator in Europe may work on another band than 2100, since there are two 3G bans in Europe. Generally operators used 2100 first and then subsequent licenses were other bands. So in Norway, I know both 3G carriers use 2100 exclusively, but you should check with your carrier and clarify that T-Mobile USA supports the EU 2100 band and not just AWS (which is a mix of 1700 and 2100).
Thanks for quick reply. 3G works on WCDMA standard? If it is so, my operator use 2100 mhz so maybe it will be working, it will be my first 3G phone so I'm not sure what I suppose to check.
I found this:
http://forums.t-mobile.com/t5/T-Mob...1;jsessionid=2085F63B05DB5B6FFA511D3C33A9EE69
According to this site TMobile touch pro 2 phone use Bands: 1 (2100) & 4 (AWS 1700/2100).
Band 1 is Europe standars so I hope it will be wroking.
I let you know when I get the phone.
Any particular reason you are getting the USA T-Mobile version and not the EU version or one from a local carrier?
Also the T-Mobile version is locked, so you will need to unlock it using the tools on this site.
If you get 3G or not should be pretty obvious. If an H or 3G icon appears, you have 3G. Otherwise if the data icon shows E or G then its only getting 2G.
the main reason is the price
tmo $450 vs eu $650
Yes main reason is the price. I get this phone for 270$ in my country it coasts about 550$. I know I must unlock it but first I must get it to my hand.
Well, it's just as the title of this thread says... I have a Tmobile's G2 (A.K.A. HTC Vision), which its 3g default bands are under 1700 / 2100. Here on my country, all the providers have their 3g services on 900 / 2100.... soo... Is it possible to Flash T-mobile G2's Radio, an set it to work on 3g 900/2100 mhz, so I can use the phone on 3G, instead of that annoying and extremely slow EDGE??
Or, is there a Custom ROM that has these settings on it? (I mean, a rom that automatically turns the 3g band to 900 instead of 1700)
Thanx.
No you can't, the radio bands are set in hardware (e.g. the physical antennae in the phone), not just in the radio software.
Why would you need to, the phone would use the 2100 band for it's 3G in your country? I took mine to Russia and it worked fine.
I don't think it's that simple. I only get edge on my T-mobile G2 using the Rogers network.
Sent from my HTC Vision using XDA app.
Rogers doesnt use 1700 or 2100 so that is to be expected. The original posters country has a 2100 3G, I would suspect he just isn't in a coverage area.

I don't think it works like that, I think it needs both bands to work. If it was that simple then surely they wouldn't bother making different phones for different markets (e.g. T-Mobile US vs Europe/Asia)
That may be...I'm only speaking of my experience in Russia, they have 2100 only 3G and mine worked without the second band.
Just to add, T-Mobile US use the 1700 MHz band for the uplink, and 2100 MHz for the downlink. So presumably the phones (i.e. G2, as opposed to the Desire Z) are physically setup like that too.
Oh I thought Rogers uses 2100. Either way, no worky.... sad.
Sent from my HTC Vision using XDA app.
Ah, I think I'm following you, because Russia exclusively uses 2100 for up and down my phone worked, but since his county has a seperate uplink and a downlink band it won't?

Yeah I think that's it. I don't know *that* much about this myself, just picked up on a few discussions about the G2/DZ on here over time.
Have a look at this - http://en.wikipedia.org/wiki/UMTS_frequency_bands
I think the "problem" is that the G2 uses exclusively "Band IV" for 3G (i.e. 1700/2100 split), but somewhere like the OP's Dominican Republic uses Band VIII (900).
What the OP needs is a Desire Z, which operates on Band I (2100) and Band VIII (900).
Russia appears to use Band I (2100) as well. Maybe a G2 can partially work there then ?
Rogers uses something else, Band II (1900) and Band V (850).
As I say, I'm don't know that much about this myself, so if anyone else can help clarify/confirm/deny, then that'd be great.
Much appreciated.
Sent from my HTC Vision using XDA app.
Via Google, I dug up another interesting piece of info.
Although it's not on HTC's official spec list on their site, on T-Mobile's support pages it says that the G2 does Band I as well. Which would explain how it would have worked in Russia. That's not going to help the OP's problem though.

Wow mega confusing, but you helped clear it up, thanks!!
Mine worked very well in Moscow, I was pleasantly suprised, it was kind of a bonus to be able to get on the web, I wasn't expecting much.
I don't understand why the manufactures don't provide phones with penta-band 3G support like the Nokia N8. Maximize profit when producing 2-3 same phones with different frequencies maybe? I mean quad-band GSM has been supported for pretty much all of the current phones, why not 3G bands as well?
Has anyone tried this option?
bring up the dial pad and dial
*#*#info#*#* (aka *#*#4636#*#*)
press "Phone Info"
you'll get the screen with the imei, phone no, network and a button that says "Run Ping Test" at the top
press your "menu" button
when the menu pops up, it'll have 6 options, select radio band, view sim address book, view fixed dialling numbers, view service dialling numbers, get PDP list, and More.
Choose the first one "Select Radio Band" then select the appropriate band.
Not sure if it helps in this situation, but I found it in a thread about gaining 3G in Europe on the N1
hey bro.. I read from one topic in TMo's official G2 forum that the G2 will work on a country with only a UMTS band of 2100 both for up and down (the answer is from TMo employee, an engineer)... hope you'll be enlightened. I bought an unlocked G2 and I researched extensively before purchase. Im from the Philippines which only supports the 2100 band for 3G. I Know and Im 100% positive that the phone will support the 3G band here in my country. cant wait for my G2 (arriving tomorrow)
btw... coverage is vital. if the 3G signal is weak or non-existent in your area, you'll be switched to edge for data on your phone (naturally).. good luck
sorry.. cant post the link. would've loved to have posted it.

That's the Band I thing that I was talking about, that T-Mo shows on their spec sheets (but HTC doesn't seem to list, for some reason).
I think the G2 will do 3G if any one of the two bands are supported by the country. Correct me if Im wrong

There is nowhere in the world that uses 2100 in both directions. Band 1 is 1900 UP, 2100 DOWN.
In all cases, your phone must be able to upload on the frequencies that the towers listen on, and download on the frequencies that the towers transmit on.
I.e., north america vision transmits on 1700 or 1900, receives on 2100.
I purchased the newly released UMI X2 Android phone. I am unable to use the TMobile 3G network. I am only able to use 2G/EDGE.
Voice and data quality are very bad, almost the phone is unusable. I spoke with T-Mobile and was informed that my modem does not support 1700 MHz and there are effort to re-farm TMobile network to support 3G on 1900Mhz but not set date yet. When I scan for available network I get three networks were available
T-Mobile 2G
AT&T 3G
AT&T 2G
Operating System: Android 4.2.1 OS
Processor: 1.2GHz MTK MT6589 quad-core processor
Connectivity Technology: GSM network & WCDMA - Standard SIM card
Network Band: GSM 850/900/1800/1900 MHz & WCDMA 850/2100MHz
Data Technology: GPRS, EDGE, HSPA
Baseband version
MOlY.WR8.W1248.MD.WG.MP.V2.P1
I would appreciate any help to get my phone to work on 3G.

Did you make any progress with this? I recently purchased UMI X2, for use with T-Mobile UK. But have the same problem of not being able to connect to 3G networks - it works okay on 2G/EDGE.
I know the phone supports 3G on 2100MHz, and there's been some debate whether it supports 850/900MHz as well, but I've not found a definitive answer to that.
There's an operator in the UK (Hutchinson 3G UK Ltd) that only have a license for 2100MHz. So I was expecting the phone to work fine on their network- but no go... phone won't register on network at all - even though it shows in the available networks list.
I'm now searching to see if anyone else has been having problems - as it's beginning to look like faulty phone hardware - rather than trying to use unsupported frequencies...
acid meaand
I am still in the same situation, I am unable to use the 3G network for T-Mobile.
I am looking into getting 4G Wireless Hotspot modem $50 from the same carrier, use my SIM card on the modem, and use my UMI X2 as pure IP phone. There are many issues, but it looks promising.
Please keep me updated with any progress you make.
Regards;
I have the same problem...
I have this same problem with a operator here in Brazil. Every 3G operator in Brazil, using 2.1GHz band, works fine except one: VIVO.
I can see the network when I click on "manual search", but the phone can't connect. My baseband is:
moly.wr8.w1248.md.wg.mp.v7.p1 2013/04/10 00:39
How can change this baseband to another? I tried to update firmware but unfortunately the newest firmware has the same baseband version.
firmware update will not solve the problem
Firmware update will not solve the problem. Until the manufacture identifies the problem and provides a solution, the problem is outstanding.
Beside the hardware has to be compatible and can support more frequencies which no one can confirm for the UMI or any other chines unlocked phones.
But, this is just my humble opinion.
I Found a solution (at least for me)
I think I found a solution for my problem. I flashed this very new (2013/07/17) rom, with a new baseband MOLY.WR8.W1248.MD.WG.MP.V7.F2.P1, 2013/07/10 23:14 that corrects 3G dropouts and disconnects. Now my 3g works find, with H and sometimes H+. Fast and reliable like it should be. The link for this new ROM is:

Thanks for the update.
I have two questions.
1- There are two files in the link you provided UMI-X2-basedon_Official_250613.zip and UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. Which do use?
2- You mentioned the updated corrected 3G dropouts and disconnects, but do you know if the update have these frequencies to get 3G?
3G (850, 900, 1700, 1900, 2100 MHz)
HSPA+ 42
P.S
GSM/EDGE/GPRS (850, 900, 1800, 1900 MHz) original specs

I used the file UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. It was based on the Official ROM from 07/17/2013, but I was unable to find the official stock version. This version has a very new bandbase that, supposedly, fixed the problem with 3G on some operators.
3G on Brazil is on 2100 MHz, sometimes on 850MHz but in my case the problem was on 2.1GHz band. Three WCDMA operators in Brazil, all in the same 2.1GHz frequency, work fine, but VIVO doesn't. Now, with the new rom, it works with no drop outs for over a day now.
no changes or additional frequencies
I successfully applied the update but no changes or additional frequencies
I have serious issues with HSDPA, t-mobile uk works but only on GPRS and it keeps dropping out. GiffGaff seems to work without dropping out. It has worked for a minute on HSDPA today but only once. Other than that t-mobile has been dropping out badly. GPRS works for a bit then it drops out. I have took an MTK modem log with MobileUncle Tools to see what it says but haven't looked at it yet. Trying to work out if it is a hardware issue or Baseband.

First of all, I live in Europe and have ZL 6502. Because of low network I entered *#*#4636#*#* and in Phone information tried to change the Radio Band but only available was US BAND. I ve tried flashing 4.1.2 - 10.1.A.1.434 - GLOBAL, and Generic LAM (b) Generic GEL 1271-5120 10.3.1.A.0.244 R5B version, but still shows only US radio band available. PLEASE HELP ME if there is ANY way how to get EURO BAND. Which firmware I should flash?
PS. My phone is not rooted, with locked bootloader, I will do it ONLY if its necessary.
Thanks

Just reload the software using PC Companion from Sony, and DON'T select a band when you're done.
I did that too... So I got a suggestion on xda to do a full factory reset. It solved the problem.
Also, try to stay away frm such settings that u know nothing about( I once did that nd had a hard time). Tinkering with them causes a lot of headaches(a lot of backuping nd stuff)
Hope it helps.. Don't forget the thanks buton on ur left
I already did that, and the phone I mean network works more or less ok, but I was wondering if there is a way somehow to change the radio band. Because US Band works on diffrenet frequencies than EURO Band, and I think it would be more compatible wit my carrier.
Thank you both for the reply

YES, I understand that, but I was asking IF there is a way to CHANGE the US Band only, via FLASHING or INSTALLING or MODIFYING firmware or something else, to have NEW RADIO BAND choices like Automatic or Euro Band, Japan Band etc..

No unfortunately there is no way that u can change bands other than provided.
I wud also suggest to ask this on another forum, bcuz u wont find many ppl here. U might wanna try Xperia Z forum or try searching on xda GENERAL.
thats the most i can help.
Good luck!
How low is your signal?
The countries of Europe use the dual band frequencies of 900-1800. The US uses mainly 850-1900.
But the Xperia ZL C6502 supports all of these:
C6502/L35H
UMTS HSPA+: 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I)
GSM GPRS/EDGE: 850, 900, 1800, 1900
Well the signal strength varies from time to time, I rarely get full network bars, usually is 2 or 3 bars. But I`ve noticed that in some places where using my HOX has full bars the ZL has one or no bars (by using the same sim card to be sure about the carrier and network strength). That is why I was wondering if there was a way to somehow change/add Radio Band on my Xperia ZL.
Please tell me when you try to change the radio band via *#*#4636#*#* does it show ONLY US Band or you might have more options to select? Please inform me, at least I want to know is it same to all Xperia ZL 6502 or just mine and those from US.
Thanks

When going to *#*#4636#*#* and then phone information, it lists info for Data which is set to LTE in my case but nothing for Voice. You need to go to *#*#7378423#*#* >> Service Info >> Configuration to look at your Bands.
Mine are GSM850, GSM900, GSM1800, GSM1900. My phone is a C6506.
My signal indoors doesnt have full 5 bars either, it will be between 2-3 bars. Outside, ill have usually the maximum but sometimes 4. At my work I have 0 bars because of the building I work in but even with 0 bars my signal never drops. The bars are not perfect, they are just a representation of your signal more or less.
As long as your signal doesnt drop, I wouldnt worry too much about it unless you have real poor reception outdoors.
Sorry for the late reply

You shouldn't have any issues with your phone. Your C6502 supports the proper frequencies which include pretty much everything apart from LTE. Only C6503 and C6506 support LTE. I don't believe you can flash a baseband to obtain LTE since it is also related to the hardware.
If you really feel like the reception is an issue, I would bring the phone back to where you bought it and have them verify with another ZL if the same type of signal is acquired by the phone but honestly, I don't think you have a problem.
But you be the judge of that....
Good Luck!
I thought also that i have the proper bands on the phone, but that`s why its so strange when using *#*#4636#*#* in the Phone info when selecting the 3 dots Select radio band ONLY shows US Band, I should be able to have more choices.
This is why I`m asking if you have the same option, or are there ANY Xperia ZLs that have more selective options than US Band only.
Thanks

I checked in my phone the *#*#4636#*#* and I I only have USA Band which I assume is normal for me since I live in Canada. But this information is for data reception (3G, H+, LTE) not for making/receiving phone calls.
The best thing for you to do is to walk in a store that has this phone on display and verify that its configured like yours so you know there's nothing wrong with yours.
for come back at your frequency you need type the code *#*#7378423#*#* and select the voice like "reset all customization".
The phone reboot and restart to work!!
Sorry for my english

That just does a total factory reset. Useless advice...
Will I lose any lte band support if I convert to tmobile?
Yes, flashing T-Mob US (I assume you mean US, since you are talking AT&T) firmware or RUU will change band support, and you will lose some LTE bands.
According to the specs on GSMarena, with the T-Mob firmware, you will have support for LTE bands 4 and 17; and will lose support for 2, 5, and 7.
What bands do you need, and what carrier are you using?
Tmo USA
What if I merely flash a tmobile based rom

Just flashing the ROM, you won't change the band support.
But again, I'm curious what carrier you are actually using the phone on?

Should work fine.
Being on T-Mob US, and using AT&T radio baseband (part of the firmware that determines band support) should be fine for the most part. Reason I say this is:
1) ATT radio supports the same LTE bands as the T-Mob radio (4 and 17), and then some.
2) ATT radio is missing HSPA (3G) Band 4 (AWS). This used to be the band most widely used by T-Mob for 3G. But my understanding, is that they are well underway in migrating 3G service to 1900 MHz (Band 2) which is supported by the ATT radio.
3) The only "negative" to staying on the ATT radio, that I can see, is that if you happen to be in area where T-Mob is still using AWS for 3G , and you don't have LTE service in that area, either. In that instance, your data will drop down to EDGE (2G). I don't really have an idea of how widespread this situation may be; but I have a feeling its relatively small.

Yea thats why I got an unlocked ATT m8 instead of a tmobile one for the extra lte bands. I have yet to run into band 2 lte and all the aws hspa has been reused for lte. Luckily.
