I read on the howard forums that i can switch radios, but idk how to do it
Can anyone confirm that it increases signal?
And how do i go about doing this

Yes, flashing a different radio could improve your signal, but its not guaranteed to. The best radio to use is the one that came with the phone, or the most updated one that released with a ROM you flash.
No matter what radio you're using, you're never going to see amazing signal improvements by switching. I would also not recommend messing with changing the radio if you're not comfortable with general rooting and flashing procedures.
Just don't go flashing new radios expecting amazing changes to happen. When it comes down to it, T-mobile may just not have fantastic coverage where you're using your phone.

No, but you need to be rooted, and flashing a radio is one of the only ways that, if something were to go wrong, you could brick your phone.
If your signal is unbearable, than after a lot of reading you should do it. But if you are getting decent coverage, and all you want is an extra bar or two, don't. If it ain't broke, don't fix it.

I assumed you were on T-mobile because your post indicated that.
But either way, it doesn't matter what network you're on, messing around with radios isn't a great idea. If you're new to this and don't want to have a chance to really mess up your device then stay away from flashing radios.
If you're running a stock ROM with no root then I would advise that you just stick with the radio you were given. Flashing radios is usually reserved for people who update their ROMs manually and need to flash the radio intended for the new ROM.
If you are able to read instructions then there is absolutely nothing to fear from flashing a new radio,obviously you must have a rooted phone,so if you can root a phone then you are capable of flashing a Radio,there is a page on xda with solid instructions,read this and you will do no harm and possibly improve your reception
switching radios is risky but like bombadier said follow directions and your all good. i did it when i was a noob among noobs and i got better bars and more 4g...well worth it
If you really wanna try switching radios then click on the link. Read Carefully and Follow The Instructions.
Good Luck!!!!

1. Download the desired radio file.
2. Rename the file to PC10IMG
IMPORTANT: You must rename the downloaded radio file name to PC10IMG in order for it to work. I did not name the flies PC10IMG in case you download multiple radio files to cut down on confusion.
3. Place the PC10IMG.zip radio file on the root of you SD card.
4. Power the phone off.
5. Hold the volume button down and press power on.
6.The phone will boot into Hboot then Bootloader, It should see the PC10IMG.zip and ask if you want to apply the zip.
7. Use the volume up button to select "yes"
8. Once its done flashing, reboot the phone and you should have a new radio.

Does anyone have a VOGUIMG.NHB of this. I tried the one for the titan it did not work. My brother have a Titan with this radio & he has service in places I do not, and I would like to be on the same footing as him.. I have a Sprint.. I've looked and I can not find a working NBH for that radio..
Radio
ftp://up.ppcgeeks.com/Vogue/Radios/VOGUIMG.3.42.40
Rename to VOGUIMG.NBH
Thanks for the new Radio
Just what I was looking for. A 'simple' radio only update. Perfect. Now lets see if the new radio [ I was at 3.42.30 ] is better signal wise.
Where do I have to put that file???
use a micro sd card formatted to fat32. copy file there. put it phone. enter bootloader mode and it will auto start. press power button to flash, when its done restart phone. easy

This may be a stupid question but will updating the radio have any impact on GPS? I know that the cellular radio and gps are on the same chip but is the radio update solely for the cellular radio?

It should update GPS, it is a catch22 in some regions like here in Salt Lake Utah the sprint radio works better for GPS but has poor signal on my phone.
does this work better than 3.42.50?
I live in Michigan (Detroit) idk about you, but here I went from 1-2 Bars with .30 and .50 to 7 with .40.. It's a major upgrade the GPS is juss a tad bit slower.

For the life of me I can't get it to update using the micro SD or through usb using RUU. Keeps telling me the RUU isn't for my model of phone. The last one I tried got to 8% on the phone and then the phone rebooted and the RUU stated I had an incompatible handset. I have unlocked the SPL and succesfully loaded NSFFANs WinMo 6.5. So I know it's not a lock issue. The SD problem is likely caused by the card being 4gb (I have read that it has to be below 2gb). I really preffer doing the update using a RUU. So. My Vogue is a Telus Touch 3050. Does anybody have a link I can look at that addresses my particular phone and updating the radio only? Don't want a stock ROM loaded. Just a radio update to help with GPS lock times (hopefully).
SD card must ben NON HD, so 2gb or less.

I'll upload them to my 4shared site here shortly.
I have the 3.42.30, 3.42.40, 3.42.50 As far as using an RUU I have never updated my radios that way but I know it can be done. Also you may want to partition your 4 gb card to 2 2gb partitions and see if that works. Also just to verify these are for CDMA Vogues AKA Touch. You will need to also use an RUU that is designated for the Touch Vogue.
This has the 3 radios mentions in my last post zipped together
http://www.4shared.com/file/143967240/244c2d8f/Vogue_radios.html
So just to be sure, out of the ones you posted, which is the best and latest radio for the CDMA Vogue? Is it .40 or .50? I have a Sprint Touch (CDMA Vogue) and I want to install NFSFAN's WinMo 6.5 ROM on it but I want to update the radio because I think that is recommended to get this ROM. Also, I would like to improve signal and GPS in general, so I want to update the radio anyway.
Also, can you please clarify how exactly I update the radio using these files. I read the post about renaming it properly (.nbh), putting it onto a microSD card with fat32 file system, going into bootloader mode, then restarting the phone. How exactly do you go into bootloader mode to install this update? If someone could link me to step by step instructions for beginners, or explain it here that would be great, thanks a bunch!
Hello
First insert an SD card with the radio properly named.
To enter BL mode just press and hold the power and camera buttons simultaneously and poke your stylus in to the soft reset hole located next to the usb /charger connector.the screen becomes three coloured.
Now follow the on screen instructions.finally soft reset after successful flashing and you are done.
I hope this helps.
Thanks for the reply. I just installed the new WinMo 6.5 ROM from vin on my phone and it worked. I still want to update my radio but I just want to make sure that the radio update won't overwrite the ROM upgrade, or make me have to do it over again.
This shouldn't happen right, like I should be able to just update the radio after installing this ROM and it should be fine?
Oh and one last thing, which is the best radio version to use for this phone? 3.42.40 or 3.42.50? I am currently using 3.42.30.
My original guess was .50, but apparently someone gets better signal with the .40 so I just want to be sure, thanks!!
Both .50 and .40 work well. .40 is newer than .50 but I used .50 for over a year and it was great.
http://forum.ppcgeeks.com/showpost.php?p=694930&postcount=1
Apparently Telus have the best radios over each system. And our 3.42.40 is equal to their 1.04.05v.. So check that list and see if .40 is in your range.

You will be fine just updating the radio it does nothing to the ROM. As for the best I think it depends what region you are in. You just need to experiment.
Hi All,
I have tried to flash a new radio on my new Vogue (Sprint HTC Touch) but for some reason I have been unable to do it. I have tried the following:
* Via SD (2GB non-SDHC)
* Via RUU in normal mode
* Via RUU in bootloader mode
* Re-downloading the files in case they were corrupted or something.
I have:
* Renamed the file(s) to VOGUIMG.nbh
* Unlocked and superCID unlocked my device
My phone is working fine with fairly good signal, but I read a few threads that mentioned that .40 has a faster lock for the GPS (as well as slightly better signal quality). I am currently on 3.37.10 and on WM 6.5.1 build 21864.
This is not my first time flashing anything by any means, but I cannot seem to be able to do this for some strange reason.
Any help is appreciated.
I actually got the RUU to start doing something but it stopped at around 30%
I have been happily flashing ROM's, creating a Goldcard for a couple of weeks since getting my Hero and have just done a Radio update. I just realised I have no idea what the Radio update actually does.
Could someone explain in fairly simple terms what it is all about, I guess I have cat blood and curiosity has got the better of me
Sure. The radio update flashes the software on the little 'chip' that deals with mobile network/GPS/WiFI/Bluetooth etc. (basically all communications).
The update changes the software to a newer version, which can give better signal and battery life (It's a bit like flashing a normal ROM, except it's only for the communications hardware or baseband as iPhone users call it).
For more info, see http://android.modaco.com/content/h...-update-zip-format-for-gsm-hero/#entry1059164 which also gives you a list of them
Thanks for the prompt reply and simple terms. I am almost getting to the stage where I am qualified to make a phone call
Ah, great, I was wondering about this too. Is there any difference which radio rom you flash apart from GSM/CDMA? (My Hero has a suspicious "EU" in it which the roms I've seen online have not. Might just be some versioning, but then again it might be "europe"...)
How do you update your radio? Do you have to wipe?
EU doesnt mean europe, it is a way of identifying the radio version, like there is JU, JH, etc.
I found this out from other sources in the mean while (and forgot about this thread; it's been a couple of weeks after all), but thanks for replying anyway, it'll surely help the next guy wondering.

In the link posted a few posts up, you'll find the radio updates in the update.zip format needed to update via recovery mode, like any other custom ROM flash to your phone. However, Radio updates are typically included in the official RUU updates as well, but those will obviously unroot your phone.
Aside from increasing battery life/signal strength, radio updates can bring bugfixes and features. Newer OS ROMs typically work best with the latest Radio ROMs. After I rooted, I had an "EU" radio on my Telus Hero, and I couldn't make long distance calls unless the phone number had a "+" in front of it in my contact list. Updating the radio fixed that. Hope this info helps.
yeah it helped
But i dont understand the order of updating. First i transfer the update of the ROM to the phone and call it update.zip and the flash that ROM. But then i have to boot up the phone, to transfer the new radio and boot that.
Can it be true that i have to boot the phone and then tranfer the new radio, and the go into bootloader and flash the new update.zip?

OK. Well, the file doesn't *have* to be called update.zip. The recovery image has an option to choose a zip file, which makes things much much easier, as you can flash several files without rebooting, although I believe you have to reboot as part of the radio flash process. With this in mind, I would flash the OS update first, then the radio update. However, it really doesn't matter what order you flash them in. While the OS and radio rely on each other for the phone to operate properly, they are completely separate and individual from a flashing standpoint. They both get flashed in the exact same way from the recovery image, however with the radio, rebooting the phone is a necessary part of the process. If you were (for some dumb reason) to flash the radio and then remove the battery before the phone had completely rebooted, you'd end up with a broken (and possibly bricked) phone.
I wouldn't flash a radio without having an os installed, so if you have wiped then flash an os first. Just to make sure everything goes smooth.
A new radio file won't install until you do the first boot after installing which from memory is forced on you, so you will want to have a rom installed.
Thanks for the information about radio, quite useful. I have tried several ROMs lately but haven´t touched the radio yet. I guess if update to more recent one can improve battery and signal as it has been mentioned before.
I will try and see how my Hero behaves

E.g. GSM (I am guessing as you are on this forum and not he sprint one)

Radio update
HI ALL
please ,if i flah the radio , i loste des root ?.
And please wish methode to flash wihtout lost the root
PS:I have the hero
thanks for help
flashing radio doesn't do anything to the rom, you won't lose your root.
thanks Lennyuk,
Please you confirm that if i flash only the radio ,the root is not pacted ?
Sorry for my bad english and my bad request
1. Root with Unrevoked3
2. Perform a "nandroid" backup
3. Install Unrevoked Forever
4. Install all Sprint over the air updates for radio, etc <-- Can I do this???
5. Install ClockworkMod and use it to load a 2.2 rooted Rom
Yes, but don't mess with Unrevoked3, it's not a full root. Use Simple Root or just do it manually like a real man using the tutorials.
Rooting will wipe your data if you do it manually, but you can use Unrevoked to do a partial root and then do nandroid or Titanium/MyBackup, just know that you'll still need a full root after that.
Also, you'll just have to flash whatever radios you want using recovery, after you root. It's all done the same way, just flash the zip file. Just watch out when you do radios, they often go through 2-3 automatic reboots during the process. NEVER interrupt the flashing even if you think it's stuck, just wait a few minutes for it to get to your lock screen and be ready.
One thing that bothers me about flashing radios is it seems like it always breaks things from what I'm reading.
Thats why I was thinking about to use unrevoked forever(so I don't have to worry about losing root), and then use the real over the air updates from sprint to update my radios.
Seems safer and more reliable to do radios that way?

Most people just mess up the process. Check the md5 sum and leave the phone alone until you get to the lock screen. Many pull the battery out thinking its going through a boot loop when it really isn't. This bricks it. It is relatively safe.
Yeah, it's usually the user that screws up rather than the software. The OTA is doing the same thing, just initiating from the OS instead of recovery. It's no safer, the radios that you find on the boards are the same files as the OTAs anyway.

Unrevoked3 + Unrevoked Forever is definitely a full root. I basically did what the OP wrote, except I used the pre-rooted stock Froyo update.

Is there a general rule of thumb with which radio to run?
I'm using the thread below which lists radios and wimax, and I at first assumed the newest is the best, but people complain 2.15.00.07.28 makes their calls choppy, and things like that. Is it safer to go 1 version back, or is there another way to make sure you're getting one that's 110% good to go?

Maybe that's what I meant.
For the record, I guess I could be wrong about Unrevoked 3 + UF. But I was right technically.
Hello, i have purchased my Htc desire Hd a few days ago and i love it. I came across these forums and found them very helpful. I decided to _root my phone and install the latest Cm ROM and all went well. When i bought the phone the supplier (three) said that i would be able to get speeds up to to 6mb on the mobile broadband in my area. Sadly this is not the case as i am on EDGE.
I was wondering is there anyway to boost signal either by app or a different radio or ROM.
Thanks in advance.
Well, it could be from some setting maybe, but if i was in your shoes i'd ask the people in the Original Thread.
When upgrading from an fairly old ROM to a new ROM, i'd suggest the flashing of a new radio.
BE CAREFUL, AS FLASHING RADIOS ARE EXTREMELY DANGEROUS.
See the OP of the ROM thread and see if flashing a radio is mentioned (if its not mentioned on the thread, dont flash a new radio, or you can ask them if you can). Normally, ROM are supplied with a RECOMMENDED radio that works perfectly with it.
So ask the people in that thread (or see the OP) if and which radio you should flash.
FLASHING RADIOS COULD BRICK YOUR PHONE, AND ONLY YOU ARE RESPONSIBLE FOR BRICKING IT
- just a little warning with a happy face
Thanks alot for your time I didnt know flashing radios was as dangerous :/ i've done it twice. well thanks for the warning with the happy face
Is there any fail safes for flashing ? anything like roms or radios ?
Thanks in advance
By 'Fail Safes' do you mean 'a mechanism that manages failures and results in minimum harm'? (just googled it )
If so, well, android itself has MANY mechanisms. And by flashing ROMs, all it does is overwrite the current files. So flashing something (given that the script to flash it is correct - if not, then it wont flash - or could flash it to the wrong place) doesnt have any fail safes, which is why, if an incorrect radio is flashed, the phone wont do anything, but when you come to boot it, it could be bricked (worst possible case).
Flashing ROMs with errors can be fixed easily if you know how. Just build a flashable .zip file that'll overwrite the files that have errors with correct files.... - determining the error could be done by using 'adb logcat'
Thanks ! you couldn't have done more Thanks again for everything i will be more cautious when flashing Another big thanks !

Hi
I've got a Bell Desire Z. I bought it brand new and "unlocked" from a guy on Craigslist, who told me it came direct from HTC as a sample for a photoshoot and was already unlocked. Sure enough, it worked with my non-Bell SIM card just fine. I now use MIUI, love it.
I've been having a few funny issues with the radio (12.28b.60.140eU_26.03.02.26_M) such as sometimes I make a call and the other person can't hear me, or I answer a call, same problem, or the call comes through all garbled. I want to see if upgrading the radio will fix this.
1. How do I know what type of unlock my phone has? I didn't put the engineering HBOOT on there, but if it is already on there, how can I tell? I've got it rooted, can I tell if the radio is already S-OFF? I've read tons of stuff and I can't figure this one out.
2. How do I flash the PC10MSgwhatever.zip file onto the phone?
3. Will flashing this break my unlock?
Thanks for taking the time to help me. You guys are the best
Answers
Hi,
to answer your questions:
1. one way of getting some information out of your phone is to use the AMT-Tool to query the device info and the security status. You can find the tool in this thread:
http://forum.xda-developers.com/showthread.php?t=1097977&page=1
The latest version 1.8.5 is somewhat wacky though and sometimes claims, that it can not query or manipulate your phone, although you are already rooted and have the right software version installed. So do not rely on this tool for further flashing your phone. But the queries usually work fine and produce results.
If you run into trouble with the 1.8.5 you might want to download and try the older 1.8.1 which seems to be more stable and can be found here:
http://dl.dropbox.com/u/26590769/AMT181.zip
You don't have to install the files, just unzipping them to a new directory is sufficient, so you can unpack and use both versions parallel without any troubles.
Another way to find out the version of your HBOOT is by shutting off your phone and then holding the ON-Button and the TrackPad-Button (that square thing at the bottom of your display) at the same time until the phone boots into the bootloader screen. There is the version of your HBOOT displayed.
2. I am not sure, what exactly you want to flash, but if it is something like a PC10IMG.zip, usually all you have to do is put it into the root-area of your SD-Card (so do NOT put it into any subfolder) and then again boot into the bootloader by the method above. Then select the first option called "Bootloader" (which usually is already pre-selected) and press the ON-Button once to confirm the choice. The phone automatically searches for any PC10IMG-Files on your SD-Card and then asks you, if you want to flash that Image.
Don't forget to delete the file from your SD-Card afterwards, otherwise your phone will try to flash the Image again the next time you boot into the Bootloader!
3. Depends. As far as I have learned, flashing only the Radio should not tamper with your root or unlock. But I am quite new to the Android-World myself and would not want to guarantee the correctness of that statement. All I can tell is, that the 2nd phone I have rooted was the Vodafone Branded and SIM-locked phone of my wife. After de-branding, rooting and unlocking it, I flashed it with the Virtuous Sense 2.0.0 ROM and in a 2nd step also flashed the latest Radio onto it. Both did NOT break the UNLOCK. But since I don't know by which method your phone was rooted and unlocked, all I can do is speculate.
But even if you should break your UNLOCK somehow, it shouldn't be too hard to re-ROOT and re-UNLOCK it by following any of the many HOW-TOs published in this forum.
You can find the Link to all the HTC Desire Z Radios in my signature. There are a lot versions available that are newer than yours. As far as I have read in other threads, you can safely flash and try out several radios on your phone, but again no guarantees on that statement.
But keep in mind, that you might also need to align the Radio Library with the Radio depending on your ROM. This thread will tell you more about that process.
Hope that helped...
