Help!!! Any way to downgrade radio from 2.15 to 2.05 - EVO 4G Q&A, Help & Troubleshooting

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.

[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.

[Q] 2.2 downgrade to 2.1?

I currently have 2.2 with the leaked radio update but the location services and gps are not functioning at all so I wish to go back to stock. Is it possible to go back to 2.1 stock using the PB31IMG.zip file from the Hboot menu? How do I downgrade the radio back to 1.0? Does the radio need to be downgraded before or after I flash back to 2.1? or does the radio downgrade matter?
Once your radio is flashed to 2.05 (newest version) you can put any rom you'd like on your incredible. You could even install your old 2.1 and it will work fine (if not better) than your old radio.
You should just be able to go to clockwork mod recovery and restore your last nandroid backup or get another 2.1 rom off http://incredibleroms.com
Thank you! I used the nandroid backup I had and everything is good. Is it possible to take the radio back down to stock if I ever need to?
the new radio is the stock radio. it's just the radio from the most recent OTA. You shouldn't ever have a need to downgrade.
so no need to have concern accepting any OTA from verizon if I manually applied the leaked radio update?

I believe the update will look at your hboot version.
If I understand correctly the hboot version is changed when I root? So applying the PB31IMG.zip will take me back to the original hboot?

Just do a wipe/factory reset and it clears the GPS issue up!

[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.

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

According to the unrevoked Wiki, your baseband version isn't supported.
Code:
HTC EVO 4G, running radio baseband versions:
1.36.00.04.02
1.39.00.04.26
2.05.00.06.10
2.15.00.07.21
2.15.00.07.28
2.15.00.09.01
2.15.00.11.19
So, you need to flash a PC36IMG/RUU of a version that IS supported. Of course, you will lose your custom recovery, but unrevoked3 will take care of that for you. And I recommend using Amon_RA v2.3 and ditching CWM.
Whoops, didn't look past the first couple numbers..sorry
