Rom and radio

Ok I know what a ROM is Im pretty sure but what is the radio?
I am completely lost when it comes to radio and couldnt find anything on it.
Thanks
BTW just got rooted!
Lol,
A radio is basically an image that is flashed just like you would flash a Rom. The difference is that you don't wipe before you flash a radio or wimax. Search the dev section for [RADIO] to locate the different radio images. You should make sure to check the instructions for which Rom you are using to ensure you flash the appropriate radio.
Basically the radio and wimax updates are images that update the code for, well, radio and wimax lol

[Question] Flashing radio with ClockworkMod?

Can a radio img be flashed with ClockworkMod on the Incredible?
No you can't do that.
Thank you, I knew the diff in the leaked radio ota couldn't, but I wasn't sure if it would be possible with a radio img.

You might want to read my thread which details the past day trying to update the radio on a phone which i thought was unrooted.

FAST question please!

If i've already updated my radio version to the latest OTA update via myfroyo5, if i flash ENG build with HBOOT volume up, will i brick my device?
Don't trust me on this, but I kind of doubt it. Flashing the ENG build downgrades the radio initially anyway, then you upgrade that to the newer one.
But why would you need to do this anyway?
haha long story.... i flashed a rom before i completed the ENG build portion of the root method lol
Been there! Twice!

[Q] Various radio questions..

Currently I am running stock 2.1-update1, with a hydra kernel and s-off.
If I update my radio, am I going to have any problems with getting 2.2? Should I just wait for the OTA to come, and flash a recovery after I've installed it? If I do the radio update early, is my stock 2.1 going to keep working fine?
Seriously, nothing on this? What does updating the radio do other than allow 2.2?

I don't really know what your asking, and I'm sure that's why no one else has chimed in. But here is my best attempt to figure out what I can do to help.
To get the 2.2 OTA to install, you NEED stock recovery.
What I would do if I were you, and this is what I am currently doing -
keep S-OFF, un-root the phone by getting the stock recovery -
try this
androidforums.com/incredible-all-things-root/99828-video-howto-unroot-incredible-downgrading.html - sorry can't post links yet. cmon MODs! lol j/k
and then you'll be able to get the 2.2 OTA and then be able to put clockworkmod recovery back on and attain root.
"If I do the radio update early, is my stock 2.1 going to keep working fine?"
are you asking, will 2.1 still work with 2.15x radio?
to put it simply - yes,
but with s-off, what I used to do, if keep a file of both the 1.x radio, and 2.15x radio on your sd card, and if you want to flash either one, just move it to the root of the sd card and either go back up to 1.x or go back down to 2.15x radio.
Thank you, that actually cleared things up perfectly. Sorry for the foggy wording.

Help!!! Any way to downgrade radio from 2.15 to 2.05

First let me apologize if this has been answered before, but I could not find my specific question nor answer.
I am on baseband 2.15 and am trying to downgrade to 2.05. When I try to flash the radio in zip format, I get an error stating that my os is to new and that everything after 1.5 will not be able to flash this specific radio. This is not the same as downgrading from 2.15.x.x to a lower 2.15x.x. So please don't point me to this type of example.
Does anyone know, step by step, how to get this done?
Thank you in advance.
Edit: hboot 0.97
Radio 2.15.00.09.01
S-off
Rooted via unrevoked forever
Newer versions of the stock ROM may not work well or at all with older radios.
You may need to rollback to 2.2 to use the older 2.xx radios. 2.05.00.06.10 came out with the 2.2 froyo rollout. The newer gingersense ROMs probably can't be used with such an old radio.
Why do you need to roll back to 2.05 anyway?

Need to get my radio to a point where the nvm is writable.
Edit: update, got the radio to downgrade by using rom manager with clockwork recovery 2.5.0.7 and flashed radio update.zip
It was an amend error. An old version of Clockwork - as you did - or Amon Ra would be needed to flash it. Next time you flash radios (or anything that gives you that error) you'll either have to find an edify version or downgrade/switch recovery again.
