Evo Unable to downgrade Radio Baseband

Spring Evo 4g
HBOOT: 2.10.0001
Model: PC36100
Hardware:0003
Android：2.2
Kernel 2.6.32.17
Baseband：2.15.00.11.19
Software3.70.651.1
PRI:1.90_003
Rooted with Unrevoked.
After upgrade Baseband, I got very bad signal and want to roll it back.
1. Tried to use cm recovery 2.6 to install zip file containing radio image to 2.05.00.06.10, not sucessful. However, every time it turn to 2.15.00.11.19 after reboot. I fell 6 vibrations during flash, do not know why.
2. Tried to use fastboot flash radio image，but I got "remote not allowed" message!
Could any body help out?
Thanks.
请高手们指点一下吧！谢谢谢谢！

2.10.0001 radio is non-downgradeable on new hardware models.

Your phone has the new block size that is not compatible with the old radios and the remote not allowed error is because you are not using the eng hboot. Unfortunately it is not compatible as is either.
You can force it to downgrade and I believe I found a way to make it work with the new block sizes, but it's never been tested.

Ill test it. Got an extra new block size

If it doesn't work though you're pretty much guaranteed to be bricked. But if it's a phone you're not worried about I've been dying to find out if this will actually work.

Yes i will sacrafice. Gettin a nexus s 4g anyways...seriously will test tho

Right on, all you need to do is downgrade to the eng hboot from the hboot and before rebooting or doing anything set 'fastboot -n 4096'
That *should* let you use the eng hboot. You still won't be unable to downgrade your radio though, although afterward it may let you flash the old radios without so much as a warning.

Ok will do. Hboot usb or fastboot usb?

Tryed this but i still get six short vibrates when flashing the radio

fastboot USB, as I previously said you will probably never be able to downgrade the radio. Sorry but that's just how it is.
Are you able to at least use your phone with the .76 hboot?

its weird.. there should be a way!!

Instead of downgrading so far back, have you tried downgrading the baseband from 2.15.00.11.19 to 2.15.00.09.01? If not, give it a try. You can download it and all of the other EVO radios from the link below:

If i wanted to go back and try Android 2.1 roms, do i have to downgrade the radios as well?

Trying not to make a new thread but....say if I am using a 2.2 Rom with the 2.15.00.11.09 radio and I want to flash to a 2.1 rom(I'm talking bout far back as the rooted shipped stock ROM from last June. Would I need to downgrade my radio? And does that stock ROM already come prepackaged with a kernel. I'm pretty sure the kernel needs to be downgraded for it to be compatible. When I got my EVO in Sept, I was already on 2.2. Never tried 2.1 but have always been curious to try it and see how much worse it is. Then I could say I've finally tried all three versions of Android on my phone and how far we have progressed

As you've stated, the problem would not necessarily be the rom itself not working with the new radios, but whether or not the default kernel would work properly. Give it a shot. The worst that *should* happen is bootlooping. At that point, you can either reboot into recovery and flash a different kernel or downgrade the radio, PRI and NV. Of course, this is my opinion. You can download the rom from here . By the way, according to the descriptions on the shipped roms, the radios appear to be included.

just read that i can't downgrade my radio because i'm running the 2.10 HBOOT and on HW003. but if downgrading the radio is not necessarily important to run a rooted 2.1 rom then i don't have much to worry about do i? also, those links you posted: i can flash those RUU's in recovery like i would any other rom? i don't want to go back to stock and be unrooted.
i was thinking of running the 1.32.651.1 rooted rom from Flipzmode, and if need to - download the appropirate kernel link next to it on the detailed ROM wiki thread maintained by Toast.

You cannot downgrade your HBOOT from 2.10 (not necessarily accurate) without a risk of problems, however, you can downgrade the baseband, PRI and NV. I've done it several times. I've downgrade from baseband 11.19 to 09.01. As well as upgrade to 04.08. I've also downgraded my PRI from 1.90 to 1.77 all while having HBOOT 2.10.

i've downgraded my PRI because of the wakelock issues.
so you can downgrade the baseband to a certain extent? only within the 2.15 radios? but you cant downgrade to the radios that were on Eclair? if i can run 2.1 roms on 2.15 radios then by all means i'm going to try it out. thanks for the info doug

[Q] Radio Question

Hi,
Just got my HTC Desire HD, downgraded from 1.72 and rooted with the CM7 ROM installed.
I still have the stock radio which came with the phone which is - 12.28b.60.140eP_26.03.02.15_M3.
My question is - I've checked the latest radio thread out but I'm a bit confused as to which one I need to ensure that my device remains unlocked?
Can someone point to me in the right direction please? Also, what is the problem in not upgrading the radio - are there any major issues that can occur?
Thanks for everyone's help.
Dan.

if you have installed cyanogenmod 7 yo should flash the recommended radio for this rom...
but its relative,,,,, also the good performance depends of various factors... bettwen that is your location..there are recommended radios depending of your location...
the best advice... you can try some radios (cm7 recommended.... recommended for your location...) and compare if the signal strenght of the phone, wifi, 3g etc its worse or better...
but when you go to download a radio IMPORTANT:::: check md5 checksum
flash it with the most harmless method that you know, like fastboot commander...

be careful mate..... a badly use of radios or flashing it wrong can brick the phone

So it doesn't matter what radio you get to maintain an unlocked phone?

Desire 2.3.3 with no Radio or Root :(

Right here is my problem, I had a rooted Desire which I was trying to unroot and in the past I had used a RUU to do it. This time round the RUU didnt work due to Hboot versions so I downgraded to a Froyo Rom. The catch is that Froyo Rom did not have a Radio and stupid me I did not flash a radio. Then I ran the Gingerbread RUU from HTCs website so basically at the moment I am sitting with a Desire that is running 2.3.3 stock but unable to make any calls due to the lack of a radio. I cant seem to be able to find a way to root the phone again and flash a radio. Any help will be appreciated.

wrong section dude

ask in Q/A
RUU comes with radio.. so find exactly ur problem then ask. and u dont need to flash radio if u have done this once..
and u can check if u have a radio installed and which version in the settings. about phone

Er.. No radio, no phone. I don't imagine it would give a slightest flicker of life!

Many thanks I checked from settings and the RUU does indeed come with a radio, the problem was my sim card. Thank you very much.

question about Jermaine151 Stock+ v3.01 and what baseband it should have?

I rooted, downgraded and s-off and , and installed Jermaine151 Stock+ v3.01
My baseband is showing as 2.15.00.07.28 Is that what it's supposed to have? Everything SEEMS to be working okay, but everything I've found about that baseband says it's for Froyo, not GB. Is that going to be a problem in some way, or should I flash a more current baseband? I am very new to all this rooting and stuff, but if anyone could tell me for sure, I'd appreciate it.
Thanks.
Jim
added during editing...Reason why I posted here, is I could not post in the developer forum due to low post count. I also read through the Stock+ ROM thread and didn't see anything about this.

The baseband is the radio, you can actually upgrade that at anytime. What you are supposed to have is entirely dependent on the radio you install. The reason it's not mentioned in the thread is because your radio signal strength is dependent upon many factors, primarily your proximity to Verizon towers.
Have you thought about installing a new radio? If so, have you downloaded one yet?

Well as Slim stated you can use which ever works best for you, but technicly stock+ is a gingerbread based rom, and radio 2.15.10.07.07 was released with gingerbread by htc. The radio your on now is from the release of froyo. Also htc evo 4g radios will work for our phones, i believe their latest is 2.15.10.0808
You can get the radios here http://pvillecomp.com/?page_id=18, they are all compatible with the incredible. There are also other radios not listed on the pvillecomp site, do a little googling and you can find them. Pvilles site are just the major release ones.

I know that I had the most current radio after the OTA was pushed to me. My brother's Inc is still stock, unrooted and running the OTA 2.3.4 His radio is 2.15.10.07.07 I think. Is my radio different because of the 2.2 downgrade that I did? If I don't notice any voice or data reception issues, would leaving my 7.28 radio installed cause any problems? I did put my phone next to my brother's phone and the signal strength dBm were basically identical(within a number or two of each other)
I have looked at a few threads about upgrading to updated radios, but I understand the risk of bricking is higher than the root, downgrade, s-off and Rom install I have done.
What is the best app for testing download and upload speeds if I do decide to try out new radios so I could have a way of comparing to find which is better?
Any suggestions on radios to try?
Thanks for any help anyone can give.

Yes you have the .28 radio because it is required to use unrevoked, and get s-off. Staying on the froyo radio wont hurt a thing, its which ever works best for you.
I think Ooklas speed test app is the best, its also available online at speedtest.net
Dont be affraid to flash new radios. Its true that it is the most common way of bricking a phone, however it still rarley ever happens. I have changed my radio so many times i cant even count. The best and safest way to do it is only download radios from a reputable source, always check the md5 sums and make sure what you downloaded is the full uncorrupted version. Never flash a radio while on low battery, and never interrupt a radio flash in any way, if it freezez while flashing do not pull the battery or jam buttons come here to xda and get help on what to do. If you do that you should have no issues.

Thanks to the both of you for replying to my questions.
I have reflashed my baseband to the 07.07 file. Everything went flawlessly, no problems and everything seems to be working fine.
Thanks again for your help.
Jim
edit...A friend at work has the EVO 4g. His baseband ends in 12.19 Is that the latest evo baseband and is it usable on the Inc? And is it available somewhere for download?

I haven't heard anything about a newer radio. The latest official is what you have, 07.07, but I wouldn't be surprised if 12.19 worked too-both phones have similar internals. That 12.19 radio may be from 2010 because these phones have been out for a long while so that is a possibility as well. But for the record, I'm here often and I haven't seen an Inc user mention a new Evo radio from December 2011 so I wouldn't bother searching for it.

I just did a search and found this http://androidforums.com/evo-4g-all-things-root/486888-new-ota-4-67-651-3-out-do-not-accept.html. It says that an update came out for the evo last month, and it contains radio 2.15.00.12.19. So it does seem thats the newest one. I cant find a download link, but i'll se if i can find an ruu and extract it for you.
EDIT: Here ya go found it, just flash thru hboot.

[Q] Should I flash radio? (Intermittent reception of SMS, poor call signal)

Greetings!
Thanks for stoppin' in. Hate to clutter the posts, but all my browsing/searching through the site thus far has lead me to older links that don't seem to answer my questions.
My history with my HTC Droid Incredible has always been a mix of positive and negative. One thing I've always been plagued by is a hit-or-miss experience with my call signal and messages.
Details:
-Incoming calls don't ring and go straight to voicemail (I use google voice).
-Many calls are plagued by static or generally poor signal.
-Text and image messages are often not received, or when they are, they often arrive hours after the fact (even the next day).
I've been told that flashing a ROM to a rooted device may include flashing the radio and that each ROM may include its own copy of a radio version. Is this true?
Is flashing the radio typically part of the ROM?
What version of the radio is considered best or most efficient for a VZW HTC Droid Incredible currently?
Is it worthwhile to flash the radio separately?
I'm currently on the beta ICS Miui rom and running smoothly aside from a small handful of buggy behaviors. I've seen these issues on stock as well as Cyanogen 7 and other MIUI ROMs. This is also my second (or third?) Incredible, having had it replaced under Warranty in the past and have typically always had some issues of this kind. Typically, I've just considered some of it to be part of the luck of the draw when using a cell phone.
Anywhos, thanks for the help, folks! If you need further details, please feel free to ask.

No custom roms come with radios that i have ever seen.
Flashing a raido may help your situation and it may not. As to which radio, it is really a matter of which one works best for you.
Here is a page with a bunch of radios that are all compatible with the incredible, even the ones labeled evo. http://dinc.does-it.net/radios

I go with the 07.07 radio (GB update version) it works fine, that or the newest Evo radio. 08.08 or 12.19. I live in a splotchy signal area and from playing with it, it seems the newest ones work best for me.

Sorry for the late reply. Thanks for the suggestions and input - I'll look into it as soon as I have a chance to get to a computer and such.
Looks like I need to re-flash my ROM as it is, given the alpha of Miui ICS I've been using isn't behaving very dependably at this time.
After I figure out a way to back things up and actually load into recovery (another mysterious issue has recently cropped up where I cannot get past HBOOT), I'll get a fresh ROM done and try another radio.
Anything I should be aware of regarding the radio with consideration to the process or eventually returning to stock if needed?
Kudos!

General Update:
I tried a number of different solutions to my recently developed issue of being unable to boot recovery. I could get into HBOOT, but every time I tried selecting Recovery, it would default into another reboot of HBOOT. ROM Manager hasn't been any assistance either, as directing it to load into Recovery only brings up HBOOT.
On a whim, I decided to go ahead and try re-flashing Recovery (first option in ROM Manager), despite it showing that it was updated to the latest edition. I then attempted to reboot into Recovery right after and ...drum roll... it worked! Go figure. -_-;; ah well! Figured the suggestion of re-flashing the Recovery might help others looking for a solution.
I'm going to go ahead and see about wiping and flashing a new, stable ROM and then I'll jump into the radio suggestions above.
Thanks again!

Naming patterns?

I'm looking at the link provided by the other person above and seeing interesting naming patterns. IIRC I'm currently on the 2.15.00.07.28.
Just want to make-sure I'm reading this right - is 2.15.10.07.07 newer than 2.15.00.11.19? I would guess so, plus I'm gathering that it was the version you suggested.
Further, what are the effects of using an EVO radio? Sorry for being such a noob, but I'm honestly curious!
Thanks.

Nothing wrong with using an evo radio. I use the 07.28 myself but its because it works best in my area.

Correct, 07.07 is newer than 11.19 radio. 11.19 was released in November of 2010, 07.07 was in July of 2011.

Thanks! Learn something new everyday.

I completed flashing the radio! Yay.
Didn't realize at first that it needed to be flashed via HBOOT (though I should've assumed such based on the name), rather than Recovery, but got it taken care of w/o incident.
Immediately, I've seen an increase in signal strength (max bands), and received a text msg that would've been sent earlier this morning. I'm looking forward to seeing further improvements!
Thanks everyone for your assistance.

i use the evo 08.08 radio and it works like a charm...i tried all the radios but i found this one works the best!

How are you guys flashing these radios to your incredible phone? I kept trying by booting into HBoot and renaming the radios to PB31IMG.ZIP but it won't flash it, because the Security mode is ON S-ON. I have the OTA GB update with 07.07 but I can't seem to turn S OFF

You must have s-off to flash radios. One question, what is your hboot version? To attain s-off for:
.92 then follow this guide here
OR
1.02 then follow this guide here
The only experience I have and can reliably speak on is installing radios while s-off AND having hboot .92. I can't speak to the success rate of installing a radio with hboot 1.02, it's entirely different and unfamiliar to me.

I recently started using the 12.19 evo radio and it is much better regular signal wise although somehow 3g seems spottier
