Radios: Big confusion here!

I've been following the developments on the recent radios, including the 2.08.50.08_2 radio thread and i must say i'm very confused. I am under the impression this is a TMOUS radio and from what i gather, TMOUS hardware is not the same as the original leo, especially the radio hardware. And yet i see all these people eager to flash their original leos with these new radios.
My question is: do we know for a fact that these radios developed for TMOUS are being developed with backward-compatibility with the original leo hardware? Is it not risky to flash our phones to run radio software against hardware it is not developed for?

its the same phone... so same hardware.

that would explain the poor audio quality i get with radios 2.07 or above. However only a few people seem to have this problem. Others report good quality, reception and battery life.

It would be nice to throw in a link or two of sources that state that the T8585 and T9193 have exactly the same hardware, otherwise it's just your opinion.
T8585 runs on 850MHz while T9193 runs on 900MHz, how do we know TMOUS radios are compatible with our original leo's 850MHz working frequency?

Also if some mod could move this to the general forum, i just realized i posted it in the ROM forum.

It's the other way around...the T8585 runs at 900/2100Mhz and the T9193 runs at 850/2100Mhz otherwise I believe they are identical (no proof, just what i've read).

I'm using 2.08.50.08_2 on my UK HD2 and it works fine, battery life seems better so it's all good!!

some have reported higher temp from the back of their devices.

look i'm not saying that it doesn't work or even that it probably doesn't, i'm just wondering if all these good folks flash it because they know it's the same hardware or because they assume so

I flashed to 2.08 on a UK Leo knowing if it didnt work i could always go back to previous radio. The decision was not hardware related

The physical transceiver in the US release may be different but that doesn't matter to the Radio stack software that these guys are flashing

Radio antenna's have to be "tuned" to the required frequency bands in order to optimise performance. This is usually done by changing the physical length of the antenna and/or using different passband filters.

Ever take an old radio apart? there are (usually) square metal blocks with what looks like a screw head in the top. That can be twisted to alter the working frequency, the rest of the radio doesn't need to be rebuilt/programmed for it to work. Same when Channel 5 started in the UK, they emplyed loads of people to twist a small screw in the back of VCR's to retune them.
Same with the radio's in our HD2s, the hardware will be the same in each unit, just the frequencies pre set differently. The radio stack shouldnt make any difference from one unit to the next, (except of course the internal operation of the stack, , battery life, etc)

sorry for dumb question but are you saying that TMOUS roms will work just fine on T8585?

Radio worth upgrading

I've been reading about upgrading my radio version (currently 2.06.51.07), does it really make that much of a difference?
I live in the UK, can anyone recommend a version?
Do I have to use a .51 version? what are the differences if I use a .50?
Thanks.

Send me a plane ticket, come pick me up at your nearest airport, put me up and feed me for a week or two and don't forget to buy me a SIM card for your mobile service provider and I'll happily try out a few radios and tell you what I think of their battery consumption with your provider in your area...

If you read the threads you'll hear only go for a radio with 50 not 51, all rom makers state this.
I've been using a radio 2.12.50 for a couple of weeks and just upgraded my rom and its perfect-clarity is crystal clear and pages load very quick in comparison to original radio

IIRC, flashing the radio depends both on the device and the base rom.
Radios for stock devices
T-MO USA - .50
Other HD2 variants - .51
Again, this is not cast in concrete... I think the radios (.50 & .51) would vary even for stock devices if the base rom has been upgraded.
Bottomline, if you are sticking to a stock rom, check up on what your operator has to offer and don't cheat. That's my best advice. Lot of chaps here have turned their Leo's into bricks because of experimenting with the wrong radio. As of writing this, there is still no fix for it.
If you are switching to a custom rom, then all this becomes moot because the rom chefs always mention which radio is best for their rom.

Thank you "11calcal" and "leepriestenator" for your responses.
"NeoGreendawg" some of us are new to this and I feel your response is not very helpful. Yes I use the search button, yes I read hundreds and hundreds of threads but sometimes you cannot see the wood for the trees, so asking a question is what I thought these forums are for, to help not to slander.

using radio 2.12.50.02_2 and living in the uk also.
this is by far the most energy efficient radio i used in the uk.
i'm not a heavy user and able to use the phone for 3+ days. though it is mentioned that the battery drain is higher than with 2.10 or 2.11 radio's when calling or playing with the phone.
call quality is good and data also good. it is definitely better to upgrade the radio from the stock radio you are using.
hope this helps you.

Calm down... I may have done it with a sarcastic tone, but I was trying to make a point : only someone in your area who's using the same network as you can really tell you whcih radio would suit you best, so you've just got to try a few for yourself and make up your own mind...
Secondly, the Q&A forum is for questions, not this one...
And last but not least, go and look up slander for me and then tell me what was slanderous about my post .

What NeoGreendawg has just said is exactly true, the Radio is personal preference and depends where you live, no advice can be given on which Radio to use, which it does state on the Radio thread, If you not experiencing any trouble there is no need to change.

Yup yup, I have flashed from radio to radio and only really seen little to no difference. I am on 2.11.50.20 and there is really no different to any of the other 5 or so I have tried.

Radio not working at all
On T-mobile*, radio version 2.5 1919.4027, using supplied headphones as antenna.
Thing simply doesn't work. I get the spinning colours for about ten seconds, then it closes. Am I missing something?
*EDIT: Sorry should have said T-mobile in UK.

HD2 with At&t US

Hi, i have a HD2 unlucked using it with AT&T US. the signal is quite bad, i dont have 3g at all, ive realised the bands dont match up but is there any way to increase signal strength or something. The signal is ridiculous at times where i have no signal at all in my house.

try different radio
http://forum.xda-developers.com/showthread.php?t=669733

Unless you bought a T9193 (look below the battery cover, is there a "Next G" or "T"?), you won't get 3G.
You might have luck playing with different radios to see if you get better coverage. See http://forum.xda-developers.com/showthread.php?t=713977 for more info. If you have a TMobile HD2, then you might want to check the other HD2 forum: http://forum.xda-developers.com/forumdisplay.php?f=631
If you have any questions, read up on the Q&A forum either way.

thats why I was asking about best/latest Radio Version for AT&T. Is your Radio Version the same as mine, identified in earlier post about AT&T Radio Version?

I have at&t (but I am using a t9193), I am having good results battery & signal w/ radio 2.12.50.02_2 (link in my sig)

what exactly do i do with these radio roms?
sorry im new to this whole thing and dont know alot. thanks

HSPL from here
grab a radio file from here
follow the steps here

Non-U.S. HD2 are not compatible with TMOUS 3G regardless of the radio Rom being used. A more current ROM may provide a better basic 2G/GPRS signal.

[Q] Forcing 3G on T9193 HD2

Success! Flashed my 1st ROM and 1st Radio. I know that to the guru's here that's no big deal but it took a lot of nerve to risk my $500 investment to the mercy of my newbieness and potential to brick it.
Now I have a few more in-depth questions for the very helpful staff around here.
I flashed Radio Leo RADIO 2.07.50.27_2 on a suggestion I saw in a thread here that stated it was the best to use on AT&T in the US. I had the stock Radio at first. I am running Artemis v331_0409_WWE which seems very well behaved and has just about all I need less the typical bloatware.
My question(s)...
What is the difference in features/performance between the stock Telstra Radio, the generic OEM radio from HTC, and the radio I have flashed? Should I be seeing any sort of improvements?
I ask this because I see all the radios published for downloading but not much on specifics as to features or benefits.
I am also interested in forcing my HD2 to stay (forced) on 3G and stop dancing back and forth between 3G and EDGE. Is that possible?
I have good signals for both 3G and EDGE but sometimes the EDGE is stronger and it drops down to it and screwing up my connection speed to a crawl.
I know that in the TMO ROM on a TMO HD2 it had the ability to select the bands (at least that's what I recall). Do any of the Radio Gods around here know how to do this or any Cooks know if this is even possible?
Any answers on this would be greatly appreciated.
Thanks!

Answered my own question
After some creative searching I found an answer to the "forcing 3G" question.
Why HTC buried the band settings in a phone menu beats me. But, I found the answer. I was hoping it would have been in a more logical place like wireless connections, but hey... what do I know.
I'd still appreciate some specifics on my radio questions as I'm not looking forward to flashing every conceivable radio to see which one works if I can at least narrow it down by getting some recommendations for the best one to use on AT&T.

there are no differences between those three radios except for version.when you are trying radios you need to run them au least a day if not two to get any idea for comparison.

Wait, you're getting 3G on ATT with the TMOUS? How are you forcing it to 3G? I thought we were stuck using Edge!

I did not say anything about 3G on TMO, the thread is regarding the T9193 (Telstra), not TMO branded.
Yes, I am getting 3G on AT&T, but its with a T9193. TMO's version has different hardware with a different Radio Chip frequency. Flashing does not change that since it is hard coded in the Radio chip.
Sorry.

If there are no differences then why are there different versions? Doesn't make sense to me. I'm not arguing your point but I am curious as to why a new version Radio is released if there are no differences. That would be like Microsoft releasing Windows 7 version xxxx12345.0 and then releasing version xxxx12345.678.1 and doing so for no apparent reason.
From what I've read, there must be a difference if the performance is different so it would indicate to me that there must be some tweaks on some parameters. I'm trying to find out what those parameters are and what they affect.

Oh well! That'll teach me to read more closely!

[Q] Newbie Just Got A HD2

I have just got a Used Tmobile Unlocked HD2 today it is running Android but don't know if its from SD Card or from the internal memory.
But I want dual boot WM7.5 (Mango) with the Android.
No Idea how to do and which HSPL, Radio & Rom Should I choose for both Android & WM 7.5 ( Mango)
Just need a suggestion and if there is any link, so that I can get all the info as newbie, it will be really helpful for me....
Thank....s in advance
P.S I have not found any thread for my ans. & that's the reason I have create a new thread, If I have done any mistake sorry for that.

which HSPL, & Radio

When you say t mobile, do you mean t mo USA? Only the USA version (the "tmous") is different.
Always and only 2.08.hspl for android and wp7.
Radio, there are two families of radios, 2.xx.51.x and 2.xx.50.x,, (shortened to ..50.. and ..51.. ) take special note of the 50 and 51. For magldr, android, wp7 you MUST have a ..50.. radio, and the 2.xx.50 xx must be higher than 06.
To keep it simple, if you DO have a tmous, the radio will already work. (..50.. radios are tmous radios)
If you have a regular hd2 (all white hard key lights) then go flash 2.15.50 radio.
If you do have a tmous NEVER EVER flash a ..51.. radio, or a non tmous stock winmo rom, or ..50.. radios lower than 2.06.50, because they will always brick tmous phones.

Yes it is Tmob USA version
Its different??

Thank you for your reply Sir
Can you please suggest me a hspl & radio for my tmous, I have found HSPL4 from your signature & the radio from http://forum.xda-developers.com/showthread.php?t=611787
that link (1st radio of that link) i.e Leo_RADIO_2.15.50.14**: MultiUpload
Can I use those or it will brick??
Thank you again

use hspl4 to set 2.08.hspl (android / wp7 will ONLY work with 2.08.hspl) and yes that radio is fine.

I have a another question here...
I flasher that 6.5 os at the day 1.
Using Mango Pdaimatejam ROM 8107 v7.2
and ICS from SD
But somehow I found there is two types of radio...
1. Hardware Radio.
2. Software radio.
As I came to know Radio version ....51.... will brick the Tmous, and that's why we have to flash with ....50.... radios. And I think this is the Hardware Radio Part... If I am wrong please let me know.
But...
http://forum.xda-developers.com/showpost.php?p=21988711&postcount=1876
Here Dxdy has given different types of Hardware as well as Software radio link along with latest rom.
Now please tell me If I use
Hardware Radio= Radio_Leo_2.15.50.14.
And Software Radio radio =5.51
Will this combination brick my TMOUS HD2??
Thanks in advance
