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

[Q]About NV 1.71 and PRI 1.77

Guys, I did a little search b4 post question here. Still had confusion about NV 1.71 and PRI 1.77.
1. According to some thread here, it says, after flashing nv1.71, the pri should "upgrade" to 1.71, so does that like nv is part of pri or what?
2. since i m still at 1.40_003 PRI, do I need to flash both to upgrade PRI? (Actually, i did HBoot way to flash 1.77, but met 4g network cannot be connected problem, so i downgraded, and try to fix the problem.)
3. After PRI flash, do i need to some update for PRL, thought the current version 60670, which was 60662 after flash?
4. should I flash in the order like this, NV --> PRI --> Radio --> Wimax?
thx in advance, really appreciate you guys here.
If you're rooted, why don't you just go here and flash them all at one time..use the COMBO by Calkulin: http://forum.xda-developers.com/showthread.php?t=715485.

Lost in the sea of searches!

I have searched for the past few days and have become lost in all the threads. I'm looking for what I believe has probably been answered numerous times but have been unable to find. I'm running my DINC with S-Off, .77HBoot, CWM 2.5.0.1 and Radio 2.05.00.6.11. I want to update to the latest radio 2.15 as well as update to .79HBoot and the latest CWM however I don't see anything on the forums on how to update HBoot or CWM. The radio thread in development explains how to do the radio, so I think I can figure that out, however the HBoot and Clockwork recovery, I cannot find threads explaining how to update. What prompted this was the new SkyRaider rom 3.3.1 needs the newer radio and HBoot to work properly. I am currently running 2.5.2 and really want to upgrade this rom. If anyone has a step by step, or can post some threads for me to research I would appreciate it.
Radio Update thread with Radio Files by adrynalyne: Radio Update
How to update HBOOT to .92 with files by adrynalyne: HBoot How To. Scroll down to the heading of HBOOT .92 for the info.
Clockwork should flash by opening ROM Manager, at the top it says Flash ClockworkMod Recovery, if there is a newer version there it will say so. Remember to backup your system by making a nandroid backup first! When I updated to .92 HBOOT, I had to do a restore of my system. I've heard this is common, so remember to make a backup!
Cool, thats what I needed, thx bro.
Hey, no problems bro! Glad to help!
I wanted to report back that everything worked beautifully. I must stress to anyone doing this however make sure you check the MD5 data on all the files you use, as this seems to be one of the main reasons people have problems. Thanks again for all the help.

You can just flash the updated rooted OTA if you wish. You will have the same thing as everyone else that way, just not the radio and 4g and pri update that comes with it....
Unless you flash sprint lovers version (the all in one)
I personally have a launch day hw003 EVO and I was also already rooted via unrevoked. Unrevoked made an update to their unrevokedforever.zip that now supports the newest radio that comes with 3.70 so what I did was this
Download and flashed newest unrevokedforever.zip
used 3.29 RUU to revert phone back to stock but S-Off stayed on because of unrevoked forever
Accepted OTA update which updated my hboot to 2.10 as well as updated all my radios safely..
Then I insalled the custome version of Amon-Ra recovery meant to work with hboot 2.10
flashed the 3.70 base rom of my choice
Thanks lenny can you by chance help me step by step. My first smartphone don't want to completely screw it up

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.
