[Q] D850 on T-Mobile Question - AT&T LG G3

Hey guys, I think I know the answer to this but I wanted to ask those who might have a better idea...
I'm using an unlocked AT&T G3 on T-Mobile - the only difference radio-wise is the absence of one of the HSPA+ bands but I haven't noticed any difference in network speed, etc. Regardless, I want to flash a new ROM on this bad boy but I think I'm locked to the 850 development, right? I'm assuming that the restrictions in flashing a ROM for a different variant are due to hardware differences and not software/radio/carrier issues, right? Just want to make sure I'm not going to brick my new phone. Thanks!

Although I don't know for certain, I would tend to agree with your line of thinking here.

I am doing the same thing as op but I'm wanting a tmo stock ROM to be ported

Can I get this to work on T-Mobile?

Hello guys, I just bought a Fuze on ebay, locked to AT&T of course. But I have T-Mobile. I have already payed the person who will unlock it for me. But if I then install a new ROM will it still work with T-Mo? and what is a Radio? I saw it has been mentioned here quite often.
Sorry for being a noob

about Radio most roms comes with one installed already i suggest to get use to flashing new roms and from there you will understand more about Radio.Good luck.
Yes
Yes U can I flash several times a week using a T-mobile USA phone plan and so far Radio wise I get the best performance from 1.12.25.19. The latest one isn't bad either it depends where you live and some other stuff I can't really explain. I stay in Houston area incase that helps. Radio as to do with how your phone handles signal like gps etc. I suggest you read allot of threads to understand more things, be confident with what your doing before you flash
Hi Ali
As suggested by gguy- the radio is the part of the phone that communicates with the mobile phone network (and gps satelites). It is not a direct reference to the FM radio function.
Try to find a new radio based upon recommendations from others on the same carrier as you.
The quality of signal strength varies from one radio to another, what suits me might not suit you. It is worth noting that the radio will also have an impact on battery life as a weak signal will drain the battery faster.
On a locked phone you will only be able to use rapheal radios, if you unlock your phone you will be free to use the radios from some other phones.
Updating the radio leaves the rom as is and thus will not delete your files.

Why no custom roms for Rogers Dream?

Can the phone really be that different from the Dev Phone for T-Mobile G1?
Seems like it would be desirable model for US 3G (AT&T). No interest in this model?

rogers roms
Last time I checked there were several Custom Rogers Roms.
Did you look at soulife's ?
(http://forum.xda-developers.com/showthread.php?t=523608)
Is there a specific modifcation that can be done to the custom roms to get them to load on the Rogers Dream?
T-Mobile's lack of 3G coverage was not desirable to me so I imported one.
I know Cyanogen mentioned somthing about it but I can't find any information otherwise.

So let me get this straight ... you imported a Rogers Dream so that you could use AT&T in the states ? umk (There are ways to unlock the TMO G1's for AT&T use)
Eitherway ... as far as I know, if you're rooted and have a nice recovery image installed, like Cyanogen's ... you should be able to (with no problem) load a custom Roger's ROM like soulife's (which I liked very much, when I used it).
Dream hardware is dream hardware ... doesn't really matter where you got it.

This is wrong, and there is a whole thread in the Dream forum about it. The Rogers Dream is slightly different hardware and we can't build custom kernels for it yet. Its being worked on, though.

Cyonegens roms don't run on the Rogers, he even has stated as much. He had a custom boot iamge at one point for the Rogers DReam but pulled it because it didn't actually work.
I would agree, in theory, G1 hardware is G1 hardware, but something is different about the device some how. It is a newer revision of the G1 and uses a different amplifier for the different 3G frequencies so who knows what other minor tweaks were done.
Yes I imported one. And I also own a developer phone which runs on AT&T. Now I think it's obvious to anyone that Edge speeds for data or less than desirable. This is simply an unfortunate state of T-Mobile undesirable 3G deployment which is hardly anywhere useful, and AT&T much larger deployment with larger spectrum assets in many markets. AT&T is no Verizon, but it's more solid than T-Mobile any day, where I live for sure. Maybe when T-Mobile goes 3G here later this year I will reconsider but for now I'm happy with AT&T, not to mention my grandfathered data plan is less than T-Mobiles and I'm constantly hitting 1 - 1.5 mbit on AT&T's 3G around here.

Maybe google hates Canadians. I find it odd that there is no developer phone with North American 3G (AT&T/Rogers) frequencies.

T-mobile 4g Radio

OKAY so I decided to update this thread:
There are two versions of the One X. One with aws bands and one without. I have a device without AWS (I am about 80 % sure). There are reports of people getting 4g on AWS with the Rogers Version as of now, and more testers need to check it out as it could still be possible on ATT.
This flash here theoretically could enable the One X radio to lach onto AWS (The radios here are for the One S Ville.)
http://ville.giev.de/?page_id=42
I have flashed all three, and although I did not get 4g, I got faster ping and a near immediate connection onto T-mobile. To all the people saying this will "brick" the phone, it does not and you have nothing to worry. But as always make sure to do a backup. The radio hacks for the Skyrocket/Note were also based on flashing the Galaxy S2 radio directly on top. This should work the same.
I'm interested in this as well. What does is involved and the risk? I don't have warranty on my phone, so I'm a little bit leery in being first.

if your rooted ull should be fine just make a back up of ur current set up. this is just a clockwork flash, it may not even flash, but if it does then there's a high chance of 4g.
i've done radio hacks before for the droid 3/skyrocket/note all from a similar concept. ex. flashing the t-mobile galaxy s2 radio on the note, to enable 4g.
if anyone could provide me with a better solution for an unlock i am sure i can get this to work. seems that the htc unlocker server is down right now
it's the same thing as flashing different radios via clockwork posted in the One X android dev forum
I'll give it a try, hopefully it won't mess anything up. So I just flash the radio in recovery. If no good, I just flash the correct radio again?
There is a one click no HTC Dev bootloader unlock in the Dev forum.

good to hear no negative results got my phone unlocked so i will be testing tonight. also do u guys have the newer sims or older ones?
I have an older sim I believe. It is one that came from an activation kit I bought off ebay. I tried the T-Mobile radio and same results, still on Edge, but still could be my location.
What in gods name are you guys doing! ? Are you trying to brick your phones? It's already been confirmed that the hardware on this phone does not support the proper bands for T-Mobile 3g!

It's not just the SOC that determines hardware compatibility. There are various radio amplifiers and filters which are tuned to the specific frequencies that the phone is likely to encounter. If a phone is going to be sold in multiple markets, sometimes the hardware filters are set up for all frequencies and some are disabled via software, but often times this is not the case.
It's not impossible that a radio reflash can make it work, though highly improbable.

Interested in this. There might be better luck flashing the tmo radio since I don't think any European operators use AWS bands, correct me if I'm wrong.
Can anyone explain why flashing this radio from a different device won't brick our phones?

I have a tmobile one s, but i also have the one from att and i am so interested on using this phone over tmobile 4g let me know if i can of help. I am using my micro sim that came with the one s and i am getting edge (asume its the latest from tmobbile 4g mucro sim. I am on 1.85 rooted but i did not unlock. though i am sure we can flash through CWM. any ways i am sure there is a way out to get 3g or 4g on the one x on tmobile did not find the way yet.
flashed both of the t-mobile modems no luck for me either, although my ping is significantly higher and connects to t-mobile a LOT quicker.
does anyone know how to edit the LTE settings. it is odd but for most ATT LTE phones they have the 1700mhz frequency i think it would be a matter of just defaulting that....
the radios also show up in my baseband so i have successful flashes
EDIT: one more thing, before i was not able to use data at all considering i had the newer t-mobile sims but now data works but on edge speed.

it's just a file in your system. it could potentially brick your phone but you can always get into recovery and restore. which is why i stated you should create a back up of your device before trying it out.
however, i was fairly certain it wouldn't do that because the internals of the One S/One X are nearly identical, they both share the same processor and most likely similar (if not same, radios).
either way, the the radios work, getting me higher ping, and working data without having to switch out my sim for an older one, hope there is a way to activate the 1700 band !
http://www.gsmarena.com/htc_one_x_at&t-4614.php
EDIT 2: apparently there are two models of the ATT One X/XL one with the 1700 band and one without

Likely the software has been changed to support T-Mobile, but the hardware (filters, amplifiers, etc) are non-existent, so you'll never get actual 1700 MHz AWS support.
Of course, this is just a 50,000 foot view perspective without actually trying it myself.

you might be right about this one but there are certain One X/XL's that do have the 1700 band found out through some searching and trying to figure out the reason behind it.
If that's correct.... the people with the 1700 band would have 4g when they flash this radio! also use *#*#4636#*#* to change network type to lte/gsm
--- for other phones though like the Skyrocket/Note they were directly compatible with T-mobile radios.
Okay, I flashed the Tmo One S radio and did not receive a brick. What I did receive is a not-so-good connection that will switch between HSPA+ and 3G quite often.
I don't have a WIND sim to test with, but I tried running AT commands on my phone and they don't seem to be working. I tried doing a network scan with AT+COPS=? waited forever and had nothing displayed.
Strange...

Rebooted and ran the commands again. Still don't see any AWS carriers.

Don't you need a wind sim to connect im pretty sure the Canadian version will work on aws
Confirmed on my end that even with the T-Mobile radio, I'm not getting HSPA+. Even when I drove by the Moscone center where 1900Mhz was refarmed during Apple's WWDC (maybe it was just that day?). I was hoping this would be like the Note and Rocket where I can flash different radios.
Any other new phone capable of this? The S III? If not, I may have to either wait for 1900MHz refarm or switch to Straight Talk.

If someone is willing to let me cut up their WIND sim (or lend me their WIND microsim), I'll re-flash the tmo radio and meet you somewhere to test it (Toronto, please).

-----edit-----
Just popped in an old WIND sim that I used to test AWS connectivity at first. Saw WIND Away with the standard radio, and after flashing the Tmo radio I see WIND Away and AT&T (AT+COPS=? shows Rogers, ATT, Telus, Bell).
I live by the lake, that would explain why ATT shows up.

How to add radiobands to the Infuse

Of course, i don't have a clue how to :laugh:
I ask the community here if its possible, for the carrier T-Mobile, to add basebands to the Samsung Infuse 4G
Its very possible as the tech is closely related... but you have to program the modem... correct?
If this isn't possible..even to gain some sort of band... root... any sort of way to gain more then 2G speeds with t-mobile..yes im using att phone and yes its unlocked... im willing to do whatever to get better speeds xD...and not switchover to att..
It is my understanding that if you flash an improper radio you will hardbrick. Have read this in the N1 forums and would guess it would apply here. The problem is more so the different bands that T-mo uses vs AT&T. Others more knowledgeable than I hopefully will post. Regards.

Possible...yes-chances of it happening...most likely not
People are asking the same thing over in the vivid section (one guy offering a $100 to the first dev to accomplish it) after a little reading...I've found that "bands" are not really bands...its just deep coding that basicly tells what frequencies to use per channel and all that...it requires software hacking to the extreme...only very extremely expierenced/knowledgeable devs and Samsung themself would be able to do it...
Here's the vivid thread http://forum.xda-developers.com/showthread.php?t=1807740
And here's a link to another thread http://forum.xda-developers.com/showthread.php?t=1548553 (that was in the vivid thread op) with a guy explaining how it is possible and proving everybody wrong that were saying its impossible
Now...I can't be positive its possible but after reading that guys arguments I'm convinced it is possible...but only the experts would be able to do it...

[Q] Which Radio for AWS on CM10.1?

Hi
I just bought an unlocked i727 (AT&T Skyrocket). In addition to unlocking it, the previous owner also modded the phone to work on AWS bands (HSDPA 1700/2100). I was all impressed by this feat, but now that I come to XDA, I find all the guy probably really did is flash the radio, which probably both unlocked the phone and enabled AWS (explained here: http://forum.xda-developers.com/showthread.php?t=2029650). Currently in "About phone", the Build Number is IMM76D.UCLF6 and the Baseband version says unknown.
The phone is running stock Android 4.0.4 (ICS), and I want to put on the latest CM10.1 stable build, but when I go to this page, it says I need a Jelly Bean radio: http://www.teamchopsticks.org/p/cm101-release-notes2.html
So now I'm worried that if I choose the wrong radio, I'll no longer have AWS bands, which I need since those are the only bands my carrier (Mobilicity) uses. Can someone please tell me which of the radios listed on the teamchopsticks blog I should use to keep the AWS bands on CM10? I'm guessing its the T-mobile version (UVMC6)...?
Thanks!
Edit: Alternatively, could I just install CM9 and leave the current radio as is? I don't really care if I have the latest android version, I just want to get rid of the stock AT&T rom and its associated bloatware.

You can't unlock the operator lock with a radio. You need both a specific radio and a specific firmware.
AWS support is not a special feature that can be enabled, afaik it's a standard function of this phone.
The Radios made specifically for this phone (Rogers & AT&T) should have full AWS support, I don't know about the others.
Also the TeamChopsticks site is mighty dated.
You should check out the official threads in General and Development.
Also these links are always good to have:
http://get.cm/?device=skyrocket
http://10.1.cmxlog.com/?device=skyrocket
http://changelog.bbqdroid.org/#/skyrocket/next
Hmmm... well do you know if its true that CM10 requires a "Jelly Bean Radio"?
Or am I better off just loading CM9? That way I shouldn't have to modify the radio, right?
Thanks!

You could try flashing CM9, then it might even say in what radio you have.
Yes, CM10 requires a Jellybean radio.
If you flash the Rogers radio in my signature or the AT&T radio you'll still have AWS and it won't relock your phone.
There's really no reason not to flash a JB radio and CM10.1.. you're not losing out on anything by doing it.

AWS 1700/2100 band in HSDPA can be enabled by flashing T-Mobile blaze JB radio...It should work on cm10.1 since it is a JB radio...
So I spent pretty much all of yesterday reading up on the subject. Since we were under a tornado watch all day anyways, I really had nothing else to do!
After a while, I found the "secret codes" (listed here: http://forum.xda-developers.com/showthread.php?t=1492700), and punched in *#1234#. This told me that my radio was "T769-UVLB7", which I believe is the 4th one from the bottom on this page: http://forum.xda-developers.com/showthread.php?t=1895400, ie the Blaze radio. That would make sense because it gels with my Android version (4.0.4). Anyways, googling that radio eventually led me to this link: http://forum.xda-developers.com/showthread.php?t=1507825 which had a ton of useful information. So thats the radio mystery solved.
From the same info screen, I could see that my ROM was i727-UCLF6, a somewhat outdated stock ICS rom. So now I know what my phone's current status is in case I need to bring it back because my other combinations don't work for some reason.
So I think I've decided to go with the Pacman JB rom (http://forum.xda-developers.com/showthread.php?t=2178402) and if it doesn't work with my current radio, I'll first try the updated Blaze radio, UVMB1, listed third in that same list I linked to above. If that doesn't work, I'll try the others in that list until I get a combination that does (probably starting with UCMC1). I'm also considering the Jedi Mind Trick T989 rom (http://forum.xda-developers.com/showthread.php?t=1818305). I'll post results when I have them!
Thanks for the help everyone!

So what you're saying is: AWS for LTE is enabled in Rogers and AT&T, but, it's disabled for HSPA by default.
I was under the impression that 2100 is used for 3G/HSPA by default eitherway, but you're saying it's not?

Didn't notice any difference after flashing Blaze LB7 radio. Vodafone has 2100 for 3G/HSPA. Already had full signal with RUXUMA7 and it was still full with LB7 and speed was the same (3.7Mbit down/2.6Mbit up)..

I would recommend you do more reading and reading before you mess with the radio flashing
Good luck

AWS (Advanced Wireless Service) protocol uses the 2100 for downlink
and the 1700 for uplink..
http://en.m.wikipedia.org/wiki/Advanced_Wireless_Services
The skyrocket has the 2100 in 3G and LTE
but 1700 is not enabled in 3G
Hence the AWS band (UMTS band 4) is not supported in 3G

Thank you for explaining this, I didn't know all the specifics.
You are correct, the Blaze radio disables LTE and enables AWS.
As you can see here 1700 is not in use in Europe. So the Blaze JB radio is of no use to me.
So in the end, the Pacman JB 4.2.2 ROM worked without a hitch. I did not have to flash the radio at all, it is still working as before.
Baseband still shows up as unknown (the nifty secret codes no longer work), and kernel is now 3.0.72 cyanogenmod.
The phone's working greatI love it when a plan comes together!
What speeds do you get currently on speed test app ?
If your goal is a rom with no bloatware you can debloate a stock tw one...Personally I can never live with cm camera...
At the moment, only about 1.5 MBps, but I am not in a good service area. Even so, everything seems to load quickly.
My only complaints so far would be the ROM itself... already crashed a couple of times, and it has a bizarre way of connecting to the computer (no USB storage mode).

So it turns out that it may noit have been the ROM after all, but GO Launcher. Everytime I get a new phone, I get sucked in by GO Launcher's sexy looks, but the result is always the same: lagginess and crashes. After switching to Apex launcher, things seem to have settled down.
In terms of the radio, I did some more traveling around today and I would have to say that reception is not as good as it is on my AWS Nexus S, so I might try some different radios after all. Just want to confirm though that if I use an i727 radio (like UCMC1) instead of a T989 radio (like the Blaze radio), I will no longer have access to AWS. Is that right?
Right now I'm thinking UVMB1 from here might be the first stop: http://forum.xda-developers.com/showthread.php?t=1895400
If you ask me , TW stock debloated and tweaked by me is my and always be my rom ...
For the reception, if you have to have the best reception for a network that uses AWS 1700/2100mhz bands for HSDPA/HSPA+ , the skyrocket is not your phone...Or you have to live with issues every now and then...
That's why your nexus s(the T version) has better reception it's a device with native 1700/2100 band support...
Try some other T mobile radios from the blaze,Hercules or galaxy note 1 (remeber you have to use jellybean radios with any jeallybean based rom) and see what gives you best reception, but again don't expect miracles...
Or another note, try a stock jb uvmc6 rom (flash a skyrocket kernel for the roation problem) and uvmc6 radio or another T-Mobile radio as a combo if it is better regarding general network performance...
Edit: answering your question,yes ..skyrocket or Roger's modem will not have 1700/2100 AWS HSPA connectivity...And that "first stop" was my first advice for you...UVMB1 radio...

Hey mahanddeem,
Thanks again for the help. Even after removing Go Launcher, I'm still getting a few random reboots/shutdowns per day - enough to annoy me. I did some searching and found out about the sticky button issue, but I have a feeling thats not my problem. Usually when the phone shuts down on its own, I have to remove the battery before the phone will turn on again. I'm not completely discounting the possibility that I have a sticky button, it just seems odd that the solution involves pulling the battery. That makes it seem more like a software/Rom issue to me, so I'm thinking of going back to a TW-based rom, but I don't want to restore my original stock with all its extra bloat-ware. All that to say that I was hoping you could tell me which de-bloated TW Rom you are using. I've found Embryo, which looks interesting: http://forum.xda-developers.com/showthread.php?t=2074328. Is that what you have?

Thanks for the suggestion. I'm trying to avoid a full stock ROM, mostly because of the bloatware and branding (I can't stand seeing a corporate logo every time I start my phone!) - this is basically the reason I put a custom ROM on in the first place - plus the extra control of course. If this is the only thing that will stop my phone from randomly rebooting and shutting down though, then I'll have to consider it. Hopefully the stripped down TW version that you recommend will help though.

Heh heh true enough I still haven't tried flashing anything - I'm still educating myself. The last thing I want to do is start something I can't recover from!

I take it you don't know how to root a stock Rom and delete the bloatware yourself?

I'm pretty sure I could root it, that much seems within my limited skill set. But first determining HOW to remove the bloatware, and then WHICH things I can safely remove... That I'm not sure of. Besides, if there are already ROM's out there that have done this, why would I duplicate the effort? I'm all in favour of doing things just so I can learn how to do them, but the fact is I have other things I need to do with my time besides fiddling with my phone (family, work, motorbike.... and seemingly endless friggin yardwork!)

It's very simple, there are plenty of ways to remove bloat, plenty of guides to do it, and charts that show what things are and if you should remove them.
Embryo would be a nightmare for you. Read the thread. If you don't have the time to research and learn, you should not be flashing things on your phone.

Do your researches, it's not gonna happen that anyone here would put a long extensive guide for you so you can "take a look" at it during your coffee time...
Everybody here is learning everyday from others' posts, problems and discussions...So either you put some effort into learning or nobody's gonna spoon feed you..
As a clue , look at Mohan deodexed stock UCMC1,flash,root,start freezing apps that you know you'll not use...Then using any root explorer you can permanently uninstall system apps...And by the way you can use a custom boot animation even on stock,search for how to...
