[Q] RADIO questions - Desire Q&A, Help & Troubleshooting

hey
Everyvhere i go i read about radios. But i don't know, why are they important? why do i need to instal a new rado? do i need it every time i instal a new rom? or are they installed with the rom
why are they so important, what is the difference between them and what effect does it have on my phone?
using:htc desire
tnx

Hiya,
Basically, the radio is the software in the phone that allows all the communications to work. These include making and receiving calls, sending text messages, using blutooth, and wifi etc.
It's a critical part of the phone's software and if you have a bad radio flash you will permanently brick your device.
You don't need a new radio for every ROM and I'd actually advise you only flash one if its states on the ROM thread you need to, or if you are having reception problems.
If you choose to flash a radio, be sure to let it run the full way and never ever interrupt it. A bad radio flash is one of the few ways you can totally and permanently brick the phone!
That's how I understand it anyway...

tnx man!

one question...
can i flash a new radio with clockworkmod recovery, or is there a different way to do that?

Use clockwork. You flash it the same way as you do a ROM.

ok, tnx...

Radio, Radio update explanation please

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

Yeah once again just make sure you install the radio for your phone type.
E.g. GSM (I am guessing as you are on this forum and not he sprint one)

So basically you just have to watch out if the radio is for GSM or CDMA and then you are good to go?

Confused about Radio Images

Right, as the title says.. I'm pretty new to this game and it's pretty frustrating, trying to trawl Google and this forum for something which can tell me about what a Radio Image is.
I want to use one of MoDaCo roms, which is used in the Online Kitchen as it's pretty nifty to pick and choose what you want, and what you don't! (I'm not so much of a fan of the Sense UI, been using another UI).
I'm confused about the Radio Image, being on Orange and in the UK, should I include the "32.41.00.32U_5.08.00.04" or, if I install the ROM without it, will my phone work properly, or get locked? I'm currently on "32.30.00.28U_4.05.00.11".
Sorry for sounding like a newbie, it's because I am! But I'm getting there slowly
Dan.
Being on Orange you can't install any other radio than what your phone is provided with, shame really. You can purchase an unlock code and then flash any radio you want though.
Thanks for the clarification! Muchos appreciated. That's pretty strange, so after you purchase an unlock code, you can flash any radio, and it'll be unlocked for good? Now that's impressive
the radio is not the radio you think of like an fm radio
the software radio controls communications within the phone, this included GSM, 3G, WIFI, BLUETOOTH etc
with the latest roms this updated radio is required as it contains features the rom needs, an outdated rom will therefore not be compatible anymore.
remember that once flashing a radio to never interrupt the process, the phone will reboot several times by itself and seem to be turned off but once you've flashed the radio just do NOT touch it, it will restart itself i promise or else you could end up with a brick
yes with orange you need to first unlock your phone and then you can install whatever radio/rom your heart wishes
You're both stars, and that is exactly what I will be doing! Mm, I've never ended up with a HTC Paperweight, let's hope this doesn't occur!

Question from a NOOB about ROM's

I currently have a touch pro 2 with the stock sprint winmo 6.1 rom.
This thing is starting to lag and causes me to delete alot of messages
that i really don't want to.
I have downloaded a copy of the energy rom and the sprint 6.5 rom
but really have no idea what to do with them. I have read about
the hard spl and that if things are not done right, you can brick
the phone. Not trying to do much with it except get it to move
a little faster without the freeze.
Help please!!!
Firstly, you need to understand that flashing a new ROM will overwrite everything saved on your device's internal memory. If you have games, documents, or anything else of value on the internal memory, you'll need to back it up before you flash. Micosoft My Phone is a good way to backup contacts, SMS, and other personal data on your device.
After backing everything up, you'll need to prepare your device to accept an unsigned ROM. Keep in mind that flashing a new ROM VOIDS YOUR WARRANTY. There is no need to ever tell your carrier about it, though, and restoring it to factory conditions if you ever need to send it in is a piece of cake. Just don't go flashing a new ROM and show it off in your carrier's stores, because I guarantee you that they will block you from your warranty.
Now, you'll need to go over to the CDMA Hard SPL thread and follow the instructions there to put the Hard SPL on your device. You can't do anything until this is done. Hard SPL overwrites the SPL on your device and allows you to flash unsigned ROMs, radios, and other things that your carrier frowns upon.
Once that is done, you'll want to go on over to the CDMA task29 thread and run that tool as directed. This erases and formats your internal memory and prepares your device to accept a fresh new ROM. Only use the task29 tool with the files it comes with. Never swap out any part of it, unless you feel like messing something up.
Following the task29, you are now free to flash which ever ROM or radio you desire. Make sure you read the information presented in the threads of the ROMs you may choose. Many contain valuable information that will answer most of your questions.
You have a lot of reading ahead of you to understand how this all works. I strongly urge you to do some research into what you are doing and read the instructions carefully in each thread I've mentioned.
Lastly, make sure that everything you flash (ROMs, radios, et cetera) to your device is meant for a CDMA device. If your try to load something that is for a GSM device, you'll have yourself a shiny new paperweight on your hands.
Thanks for the info. Now if i want to flash to a new rom or update to 6.5 do i need to flash a new radio?

[Q] Reception...

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 !

Your Welcome , anytime

Flashing new radio without wanting to loose data, possible?

As topic says, is it possible to flash a new radio on my Desire without having to flash anything else, wipe any data, so without loosing anything I already installed on my phone?
Coudln't find this anywhere, since everywhere this term comes out is at installing a new custom rom, and I already got it installed and so.
Thanks for your help
flashing a new radio won't overwrite any data other than the old radio. You won't lose anything.
wow, thanks! that was a fast answer!
It's cause I read the new radio fixes some wifi-power problems and it's exactly that problems I have now I feel confident into flashing the new one checking md5 on download and everything
