i think you made a mistake typing your spl, i suspect its actuially 2.10.0000
use hspl3
if it really 20.000.0, then are you sure its a hd2??? hehe
oh, and be sure and do your rom search in THIS dedicated tmous (tmous = t mobile us, , you did mean from tmo us didnt you? your phone is different from all the other hd2s) section, you are currently in the regular hd2 thread, and not all roms are compatible.
ohh, yes its 2.10.0000 okay i'll download the HSPL 3 and install it and get back to you. thanks so much, yeah i mean't tmo us. oh i see there's regular hd2 and the tmobile hd2.. i see okay sorry am kinda new to all this. thank you so much.
no worries.
one word of caution, read a LOT before you start to flash, most things are recoverable, but the wrong radio will kill your phone, it will NOT be recoverable.
radios have versions of the form x.xx.5x.x
the red bit will always be either 50 or 51. You must NEVER flash a 51 radio.
See posts 1 and 2 HERE (the tmous radio thread) for a list of compatible radios.
(To be honest, you needn't worry about radios for a while yet, there is no need for you to change radios for teh roms you will be flashing, so get used to rom flashing before you start on radios.)
Happy flashing!
wow, this is exactly the type of thread i've been searching for. i, too, have a 1024leo (tmous hd2), with 2.10.0000. so is flashing a bad radio the only way to brick?

well wouldn't say the only way there are other such as losing power mid flash, But wrong radio on 1024 leos is a definite brick

Hi everybody,
This is my first post here and first of all id like to say "THANKS FOLKS" for the great job you are doing here just for your passion!
Im writing for Italy and im about to get an "english" (from U.K.) genuine and not branded Htc Tytn so, dont worry, im not about to bother you with questions about italian dumped roms or stuff like that!
Tytn will be my first pda phone and my first "experience" with WM 5 so, before posting, i tried to read as much as i could just to avoid posting old questions, but i didnt find anything to make it bright: if id like to upgrade the rom, the extended rom, the radio rom of my tytn with a genuine htc rom, extended rom and radio rom without upgrading the bootloader, how can i do that?Is it possible?if yes, how?
I ask that coz first, i suppose my tytn will come with the 1.04 bootloader since its brand new, second coz id like to be able to just upgrade the radio rom without upgrading all the rest and third, coz im not really intersted in making it "super cid" or anything else since i wont mount any other immage than the htc ones...
I dont know if i said something wrong or already asked and, if yes, my apologies...if not, i really hope to get some answers...
Tnx everybody and see you next post...
Greeting, Jello

Hi Jello79 and welcome to XDA-Dev, I see you've done your homework of reading and searching before asking, and no... your question has not been asked before, so we're not going to kick your ass yet (just kidding!)
If you extract a shipped ROM you will see there's a NBH file which contains the following ROM parts:
Bootloader: IPL.nb & SPL.nb
Splash Screens: MainSplash.nb & SubSplash.nb
Radio: GSM.nb
Extended rom: ExtROM.nb
WM5: OS.nb
This NBH file has a signature generated with a private HTC certificate, and if you change a single bit of it, the signature will not be valid, so the bootloader will not accept to upgrade the device showing an "invalid cert error (255)".
So the answer to your question is unfortunately "no", you are not able to flash other ROM parts without flashing the bootloader, because all existing NBH files contain a IPL & SPL on them.
Hope it is clear to you
Tnx pof, fast, detailed and bright...now i "just" have to decide what to do..do you have any suggestion?
I think it worths to update all the shipped rom to the newset one...even if it avoids me to upload only the radio rom...what do you think?
Last question:making my tytn a "super cid" one, would make the warranty void?
Tnx in advance,
Jello

Sorry I can't answer that... depends on how you want to use the device and what do you expect out of it, and how happy are you to loose time changing roms, applying registry settings, installing cabs, etc... If you're a business user with no time and mod to play with it, I'd keep the shipped rom, otherwise I'd go on with upgrades.

Just thought it was better to have one thread in regard to the locked radio included with the "RUU_Hermes_HTC_WWE_2.05.255.1_6275_1.34.00.10 _108 _Test.exe" update. I was one of the people who ran the full update and have now a locked radio bootloader If anyone has any suggestion or ideas on how to reflash the radio part could you post them here in one place!
Oh for what its worth I don't have any issues with this radio I would just like to be able to flash a different radio in the future

You are able to flash different radio, in NBH format and with bootloader 1.09.
Also I recommend you to read this thread:
http://forum.xda-developers.com/showthread.php?t=289173
Thanks pof, It all makes sense now! I must say coming from the wizard and universal I'm finding the hermes flashing process allot more hazardous! Theres seems to be allot more effort by HTC to lock the phones down! It’s a real shame as cooking roms and mixing and matching radios with rom is a lot of fun and keeps interest in the phones long after the newness as worn off.
Oh BTW I hope people in the same situation will stubble on this thread instead of posting another "help I cannot flash my radio" post.

Yes that is mine. It is Radio only 1.34 using Des SSPL. I must have not changed the text file so SSPL reports 1.23, but after install the Radio ROM reports correctly and IS 1.34
is it true ?
Is 1.27 still the 'prefered' radio rom?
I prefer the 1.35.00.11 myself since its the absolute latest radio code available fttb. GPS functionality means that if the hardware mod works then this radio will control GPS as well.
Hi Guys
NEVER FLASHED THE PHONE BEFORE.
I am not really sure what I need to do up update my Vario 2 (UK) to the latest radio ROM 1.35.00.11, never done it before and really want to enable the GPS.
Hopefully if I get that done I will flash up to WMXL 0.10
Cheers for any advice.
If I flash 1.35.11, would my BL level change from 1.07 to 1.08?
Would I lose the ability to flash radio roms using mtty?

i already opened a thread about this and noone seems to be answering the question.. i am afraid my device is ruined already and most likely because of the new spl.. i am so upset.. the whole device is acting wierd, i even went back to ap3 and still having the same problems.. it seems to be the spl coz nothing else changed! i want to flash stock rom. any idea how to go back to normal???
Guess, all bros here prefer we have our device upgraded then otherwise.
I too encountered the bootloader loop after executing the AnthenaUpdater.
Best of all I cannot load AP4 and I cannot goto activesync mode.
Seeing the bootloader screen tell me there is hope, so next.
I flash AP3newspl by cmonex, http://htc-hackers.com/uploads/ap3newspl.zip
Not sure I re-flashed the AP3 rom, sorry, quite excited during the recovery process.
As soon as I get to see AP3, I continue instructions as prompted on screen until I have the
Activesync running. Once the sync is stable and established good connection with pc,
I immediately proceed and re-try flashing AnthenaUpdater.
It finally flashed the AP4 rom. The princess found the frog.
I hope my little experience may of help to you. Cheers.
I;ve also learn to leave the usb cable connected for a little longer to ensure all activities are completed.
hi, me too
I felt ap4.0 maybe is slow so i tried to go back to 7510(or 7501) original rom but stopped at loading..... scene
So i tried tried and flashed ap3.0 rom and t-mobile ...... but everytime rebooting device is starting as hardresetted.
Never come back to original rom never go to ap 4.0
so after rebooting ,as above posting, while activesync is active, I ran apupdater but the bootloader didn't come but hard restting_after scene so ap 3.0 or 7501 rom was starting....
desperatly, as soon as updater was finalized and before bootloader started, I pressed down volume_key+camera key +soft reset hole....
manually loading bootloader...
I succeeded in flashing ap 4.0
And felt good operating.
Everybody can experience this case .
This is from spl ver. I think.
^^
As far as you willingly go back to ap 4.0, your device will remain beatiful athena.
I think some explanations needed......
Is this my own world's case?

Really everyone should read this and all the info available before you flash!
as you have found out, there is no way to revert to the old SPL yet!
I downgraded to AP3 Old SPL, It runs fine. However, I got the following error with other Roms downgrade:
"FOUND SPL V1.20
DOWNLOAD SPL BEFORE V3.03 IS NOT ALLOWED"
What does it mean?
It means, as has been said MANY times before, if you upgrade to AP4 you CANNOT downgrade to anything except the hacked AP3.

Why didn't you read before upgrading? It was made quite clear that this was a now ROM that required a new SPL and could not be downgraded. Olinex has since made a version of AP3 that you can downgrade to and in future a full downgrade path will be available. It is not available yet.

install input method ~
Needing Downgrade - Waiting Patiently
First off - the AP4 is an excellent Rom - Great work! Thanks!!!! I was an early adaptor and unfortunately my headphone jack shorted out my internal speakers and now of course trying to reflash to the original HTC wm6 shipped rom so I can submit it to warranty, I found the dreaded spl-v3.50 not acceptable warning. Yes, we were forewarned about this (though I confess I missed it). So I URGE any of you who are still under warranty NOT TO UPGRADE to AP4 until Olipro benovolently provides us a true downgrade path to the factory roms or you are absolutely positive you don't want to make a waranty claim. If you are not under warranty - I highly recommend AP4. If you are under warranty I highly recommend staying with AP3 as you can downgrade AP3 to the original factory roms.
My two cents worth as I wait patiently for Olipros downgrade path to the original roms - and I will be donating handsomely for this...
hello
any progress from the dev team ? it is a great rom but for sale our athena it is best to downgrade and to instal a shipped rom...

are yiu sure this isn't just the problem that has affected just about every HTC phone and is easily fixed by poking either the headphone jack in and out a few times or wigling a matchstick/paperclipin the hole?
No need for a waranty claim!

Not only from HTC, I encountered it with Atom and HP6828 device as well.
Poking to correct the contact may help but do not apply too much force.
The jack cannot be replaced individually, whole main board have to go,
as I learned from the service centre.
Diamond radios can now be flashed to the Raphael.
Ive got 1.00.25.05 flashed right now and its a lot better than any Raphael radio.
I had some problems in the begining but Olipro helped me.
1st you security unlock, here : http://forum.xda-developers.com/showthread.php?t=426609
2nd chose the option "Security Unlock" on you PDA in the last step and press "Commit Changes".
3rd download any Diamond radio (NBH) of choice .
4th you have 2 basic choices to make it flash:
1) extract radio from NBH, rebuild for Raphael (bit long winded but of course words)
2) open the NBH in a hex editor and substitute "DIAM*****" for "RAPH*****" or RAPH10000 or RAPH12000 (depending on whether your SPL screen says 100 or 120) - stick with wildcards first and use the exact values if it continues to complain.
I used this HEX editor : http://www.hhdsoftware.com/Products/home/hex-editor-free.html
Olipro recommends XV132 and its free.
5th now put the edited NBH (radio file) in the same folder as Raphael Custom RUU. Heres a link to the RUU : http://forum.xda-developers.com/showthread.php?t=410761&highlight=customruu
6th now flash !
And remember all of this information was provided to me by Olipro via e-mail, without me even asking (I was using the unlocker again and again and he noticed so he shot me an e-mail). Im just passing the information further, all credit goes to them !
Keep up the great work everyone !
Hi hope some cheef can convert the diamond radio roms to touch pro to avoid we brick out toys
Can you please explain what exactly is better in the Diamond radio's compared to the Raph radios? IE Battery life, reception, GPS?
And of course this may be a stupid question (well, for sure a stupid question!) but how 'bout US 3G?
Thanks!

nothing's better... but if you're bored and have nothing better to do...
OK, well, some will claim performance increases etc etc, the truth is, it's entirely subjective, and the current Raphael Radios are in fact just modified versions of new Diamond ones.

That's what I figured... Same hardware, probably just slightly modified radios for both devices... Well, I'll keep my current radio for now until I hear something really ground-breaking...

I looked under phone settings and it does not show the US 3G 850MHz frequency. Which this radio (1.00.25.05) supports on the Diamond. Dont know what thats all about........
The reception (phone and data) is better and faster what Ive seen so far. Its 1040 PM here so will test GPS tommorow and need more time to see the differences in battery.
Can you upload modified Radio?
it might not be entirely subjective, it depends on the area where you are. in any case the more choices the better.

the truth is, the raphael radios (both the ATT 1.01 and the "european" 1.02.25.31) support both 850 and 1900 Mhz 3G. it is confirmed because they've been flashed to a Fuze.

Does this mean that the Fuze has different hardware to support these ?
Ive deleted the radio I used to flash but I can make a new one if you want. Just tell me.
Edit : Ive just flashed from ROMeOS to DCS (latest) and the 850/1900MHz options are now visible in the settings. But I cant test them since Im in Sweden.
I'm in the US. If you send me one of the Diamond radios I can test it on different ROMs to see if 3G is enabled with the diamond radio.
Ok heres the Diamond radio Im using. Ive edited it to work on the Touch Pro.
Heres a link : http://rapidshare.com/files/146154003/Diamond_Radio_1.00.25.05.rar.html
well i've just brought the security unlocker and did the hex editing and i confirm that the radio from diamond works. Going to test it the next few days.
thanks for the file. I downloaded it. Do Ihave to use the Hex editor or just flash it directly to my TP?.
update:
I've tried to to the Hex edit but I cannot find any reference as specified on the first post. I might require your help as I'm not an expert. thanks
I've tried both RAPH***** and RAPH10000 as specified in my SPL and during the flashing process I get to 100% but the last page shows "error[226]: Flashwrite... flashwrite error UI535.
I've tried a couple of times with no luck. any clues?
Have you security unlocked ? Theres no need to HEX edit the file ive uploaded Ive already done that.
I think my device has been security unlocked. I was able to flash any rom radion in the past. is that right?. if not. do you have any tool i could use to security unlock it?.
correction: think what i did was to replace the hard-spl. I tried the link in your post #1 but no luck to get the security unlocker. any help?
thanks
You have to donate to be able to get the security unlock. Heres a more direct link : http://raphael.htc-unlocks.com/
good. I've donated and i'm waiting for Olipro to send me the information.
thanks
I installed HardSPL and was able to flash a different radio.
Security unlock just enables you to sim unlock aswell right? I've tried searching the whole of xda & google but can't find a definite answer that convinces me I need to security unlock if I already have HardSPL installed along with the fact that my Touch pro is already Sim Unlocked.
Sorry if this is a silly question...
edit: sorry i should learn to read because moisesz asked the question...sigh...i'm still none the wiser.
Have no problem donating but just need to know whether I need to security unlock.
hard-spl and security unlock is different, this for a fact i know... whats the different? beats me
Hey everyone.
I read it on the wiki that flashing 1024mb Leo with 512mb Rom would certainly cause a brick, I also read those scary posts about phones dead even with HSPL flashed, so I ask a question: Is there something else you should NOT do besides what is written in RUU itself?
Is it possible to make some kind of tutorial "how not to brick HD2"
P.S. Sorry if it is already stated somewhere, but all I could find were posts about already bricked HD2s
Might sound like a stupid question for all advanced users, but i find its a very good question, because of course, bricking anything (unless its a real brick) is a real bummer!
So yeah, i was also wanting to know what NOT to do, and what things to avoid..
For example, i installed HSPL 3 with a 2.02SPL, people say i will have stability issues.. i didnt read about that in HSPL3 tutorial.. will those stabilioty issues possibly lead to a brick?
Also, installing HSPL 3 and then installing HSPL 2 will those things possibly brick an HD2? or to brick an HD2 you must really be doing crazy stuff, like
-flashing 1024 with 512 rom?
-flashing crazy custom & terribly cooked roms?
best advice I ever saw on here......
"Read Everything, Even If You Dont Understand It....... Then Read It Again"
this does not change anything, I read the stickies and flashing guides and still i could only find one definite how-to-brick: 1024 to 512 and vice versa
Anyone?
That was more of just a sort of general piece of advice.
Wasnt suggesting you need to do more reading...........
Its actually the radio that will brick the device.......
flashing a .51 radio to a tmous will brick it.
So .50 radios only. You'd probably be best to go for one above 2.08.50......
Most roms will reccomend a radio to use anyway.......
If you've read the stickys, got the right rom/radio/hspl and familiarised yourself with the process then theres not much that can go wrong.........
95% of the horror stories on here are down to people not doing their homework....
I dont understand this radio thingy... Why is it even changeable?
Who would want to tweak that (except cookers?) and why did they provide different radios?
How do i know, when i download a rom what radio is it? If i use always official roms, i have no risks, right? Can even stock roms have different radios?
Thx for answers!
Radio is a part of firmware (part of ROM if you please) that ensures the link between OS and radio (GSM, FM, BT, WIFI),I read somewhere that it somehow responsible for camera aswell...

Custom roms usually do not come bundled with a radio. The chef nearly always recommends a radio to use with the rom.....
Stock roms come with a radio, which is normally shown as part of the file name....
ie. RUU_Leo_S_HTC_WWE_3.14.405.2_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship
If your flashing a tmous with a stock rom you still have to make sure that it is a tmous rom........
Wow, thanks for those clear answers! Im starting to get it!
So.. say i download several roms:
ROM: 3.14.406.2 (on HTC website)
AND
RUU_Leo_HTC_NLD_1.66.404.1_Radio_Signed_15.30.50.0¶
7U_2.06.51.07_Ship (found on internet)
AND
Original HTC NLD 1.48.404.2 2.05.51.05_2 15.28.50.07U
How do i know the radio of the first rom?
And how do i know that the Radios of the 2 other roms ( Radio_Signed_15.30.50.0 7U_2.06.51.07_ and the last RADIO 2.05.51.05_2) are compatible? Indeed, they are different, so how do i know if i can install them without bricking my device???
Thanks again, guys for ur help and time
I didn't completely understand what you just wrote , but i somehow feel that answer to your post is what i'm looking for also
The 3.14 Rom you downloaded from the HTC site already has a radio so you wont need to worry about compatibility........
Just so I'm clear on this, which type of HD2 do you have? tmous / Standard (european) HD2 / Australian (Telstra) HD2.......
Im assuming it asked for an s/n number when you downloaded 3.14??
If it did and yours worked then you have an unbranded handset and you can go ahead and flash that Rom.
If you've flashed before you will need to remove HSPL.........
If not then ignore that...........
So in simple terms, ONLY the radio that contains .51 will brick a T-Mobile US HD2 phone, but .50 will be fine. Usually all [ROM] in the Rom thread will tell you if it's T-Mobile Compatible or not. And most of them don't have a radio built into it anyways.
Every Rom you download from HTC will contain the ROM, and RADIO, so before loading you must make sure it is for HTC T-Mobile US not UK, which is usually stated before you download as you have to put in your SN number before you're able to download.
