[Q] Flashing radios, kernels, firmware after unrevoked forever

I've been reading through the forums since the release of unrevoked forever... Flashed it, I'm s-off and running. I was going to hold off until OTA released, but got bored today and decided to mess around with all of this now.
So today I flashed the 2.15 radio that was leaked to the board. After that, I installed SkyRaider 2.5.2 from Clockwork in recovery, which I believe also flashed a new kernel.
My question is... since unrevoked forever and s-off, I can flash between pretty much anything without issue, right?
I found a stock 1.00.03.04.06 radio flash file on here as well. So I restored back to stock 2.1, and then put the 1.00 stock radio on the root of SD card, booted into HBOOT and it flashed back the stock radio.
Is there any issues with doing this? I got excited to be back on Froyo (did this weeks ago with another version of SkyRaider, the leaked OTA, etc... But then went completely back to stock with RUU, re-rooted, etc)... I just want to make sure that doing this isn't going to cause any issues. I would assume at this point, with s-off, it doesn't matter... But, don't want to mess up the phone.
Also - Can someone on stock 2.1 who is also waiting for OTA confirm my versions?
Firmware - 2.1-update1
Baseband - 1.00.03.04.06
Kernel - 2.6.29-cc1c2268, [email protected] #1
Software - 1.22.605.2
I know from the unrevoked wiki they say that running different hboots, radios and kernels might result in an unstable phone.
Thanks.

If I'm reading this correctly it sounds like you bravely accomplished something that everyone has been speculating and wondering about since Forever was released: Downgrading a radio by simply flashing it.
Correct me if I'm wrong but I think most were afraid to try it for fear of bricking.

Yes I would like to know also, are you saying that while being 2.2 with 2.15 radio you loaded the 1.x radio img and just flashed it in Hboot? Or did you go through the RUU downgrading method?

Haha... I didn't realize I was being brave. I thought I was just following what everyone else did.
My process was.... On 2.1 update 1 with 1.00 radio... I then flashed the 2.15 radio using HBOOT. It started fine, checked and saw 2.1 update 1 with the 2.15 radio. Booted into Clockwork and did an install of SkyRaider 2.5.2. That was running just fine... But I decided that I wanted to go back "stock" and would wait for 2.2 OTA.
So with that, I found the radio and recovery from on http://adrynalyne.us/. That zip contains just the radio image and recovery (radio 1.00). So with that, I did a restore in Clockwork back to my backup of stock 2.1... Shut down after it restored, booted into HBOOT with that zip of 1.00 radio from the adrynalyne website and it restored back to 1.00 radio.
I did not RUU or anything else. My understanding of s-off was that we could flash pieces one at a time without running into issues... That included radio, kernels, etc.
Everything seems to be running just fine from yesterday through today.

So maybe you just made history because I've been trying like hell to get out of someone whether that was possible? From that point you could I guess flash the ota to take you to 2.0 if you wanted? I am not interested in going back to 1.x but maybe 2.0

The following post seems to say the same thing (http://forum.xda-developers.com/showpost.php?p=7692494&postcount=190)

here's what i did:
my brother has a DInc as well so he let me use his phone to mount my microSD card. I removed the 2.15 radio and put on the stock one 1.00.03.04.06 back on the root of my microSD. put my microSD back in my phone booted holding down volume and power. installed the downgraded version and phone is working again.

I can't confirm re-installing the leaked OTA that upgrades you to 2.0 radio... But I don't see why it wouldn't work.
I seem to remember a post that warned about constantly flashing radios when s-off first came out though.
I have a new post on the 2.15 radio thread in the development forum for more clarification about going from 2.15 to 1.00, etc.

Someone help...will unrevoked work for 3.3?

I downloaded unrevoked 3 ive rooted mine and my girlfriends phone with no issues. However we have had our evos since the 1st day they came out. Will unrevoked work for 3.3 on the evo? If not is there a simple way someone who isnt to good with computers like myself can root these phones?

If your HBOOT version is 2.02 or 2.10, then no, unrevoked will not work.

From what I am reading... if you say you got your EVO from day 1, I assume that is June 4th, all EVOs from that date are from 0.87 HBOOT so yes, unrevoked would work for you.
Check your HBOOT version just in case.

I think what you want to know, is how to update to a 3.30.651.3 rom and keep root?
If that is what you are asking, then yes, you can look for one like in this topic:
http://forum.xda-developers.com/showthread.php?t=836728
You can download it and follow the directions, its easy. You should already be rooted, so if you install a rooted rom you should be OK.
If you are still on 3.29, make sure that you have S-OFF and ran Unrevoked Forever.

BASICALLY YES I BOUGHT MY EVOS THE 1ST FRIDAY THEY CAME OUT JUNE 4TH I BELIEVE. IVE NEVER DID ANYTHING TO IT EXCEPTH DOWNLOAD UPDATES SENT BY SPRINT. I FPUND OUT ABOUT ROOTING FOR FREE WIFI. DOWNLOADED UNREVOKED. DOWNLOADED THE ANDROID DRIVERS I GUESS BC IM USING WINDOWS 7 I NEEDED THEM. PLUGGED MINE AND MY GFS PHONE IN AND BAM! UNREVOKED HAD ME ROOTED IN MINUTES. SO I START GETTING A LITTLE COCKY AND GET ON THIS FORUM AND SEE IM WAY OUT OF MY LEAGUE. IM TRYING MY BEST TO SOAK IN AS MUCH INFO BY READING ALOT OF THE INFO IN THE Q&A FORUMS. NOT EXZACTLY SURE WHAT FLASHING ROM IS NOT SURE WHAT A KERNEL IS. FROM READING WHAT EVERYONE ON HERE IS DOING IAM WAYYYY BEHIND THE EIGHTBALL LOL. SO WHATS A EASY WAY FOR SOMEONE LIKE ME TO ROOT THE NEW EVOS. WILL UNREVOKED WORK? ALSO WHAT DO YOU RECCOMEND SOMEONE LIKE ME DO TO AN EVO THAT HASNT REALLY BEEN MODIFIED EXCEPT UNREVOKED?

I keep hearing everyone say use the "like a boss" method

Ok...so you first got the EVO when it came out in June, rooted it, but then applied a Sprint OTA update and lost root?
I'm not entirely sure what you are really asking because if you already obtained root, why would you need to root it again?

No i havent lost root. My phone is rooted. My friends have the new evo with the 3.3 software. Before i tell em to drive up to baltimore from richmond i wanna make sure it will work. Thre reason i posted the info about my phone is i guess it would just be useful for people to see what exzactly i have and would need

Ok...that's what I was thinking at first.

So this spec is his phone or yours? If this is his phone, then you can use unrevoked3 (I assume since the build is 3.29, the HBOOT is 0.97 or so).

No this is my phone
He just bought his from radioshack 4 days ago so im assuming he has all the newest software. Also thanks for explaining the difference in unrevoked 3 and forever on my other thread. Im assuming i need to save any info on my phone before running unrevoked forever. Sorry to be bouncing around so much but im just so anxious to learn so heres 2 questions
1) when flashing roms, is unrevoked 3 a tool i can use. Can i just click custom then select the rom i want to flash?
2) for my buddys phone, what is the simplest way to root his phone since unrevoked will not work. Im reading the tjread everyone is referring to as 'like a boss" but its not making much sense

1. I assume from you asking about unrevoked forever, you are still S-ON and trying to get S-OFF? When you ran unrevoked3, it should've installed a custom recovery (ClockworkMOD is what unrevoked uses I believe). That's where you flash unrevoked forever and any custom ROMs later (the files need to be on the root of your SDcard - meaning not in any folders).
To get to recovery: power off, then when you turn it back on, hold down VOL DOWN and POWER and that will put you into bootloader. It may attempt to locate PC36IMG.zip/etc files but you prob won't have them which is fine, after that, select Recovery and hit Power and you should be booting into recovery.
If you can, I would suggest doing a nandroid backup of your phone so in case anything does get messed up while flashing, you can restore back. To do this, go to backup or something like that (sorry, I use Amon_RA's recovery so the wording is most likely different). Once you are backed up, go to 'install zip from sdcard', then 'choose zip from sdcard', and then pick the file you want to flash. After that, reboot and you should be good to go.
Some custom ROMs require you to do a full wipe (data/cache/dalvik-cache - wipe each one twice) before you flash, so to do that you go to recovery and choose the wipe option. Stuff like radios, kernels, themes, you only need to wipe the cache and dalvik-cache.
2. As for your buddy's phone....I am not too familiar with the new EVO root methods but I think the "like a boss" edition which is now updated to "Yea, I'm On Top" edition seems to be the new way to root the new EVOs until unrevoked or someone else comes out with another way. You can check out these threads to get a better understand and post in them too if you have any questions and the guys with experience when those methods should be able to help. Sorry, I can't be of too much help here.

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.
posting & replying via the XDA Premium app.

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] From Myn 2.2 RC4 TO: Newest GB w/ radios...

Okay, so here are the specs of my phone:
SUPERSONIC EVT2-2 S-OFF
0.79.0000
041f
Radio - 2.05.00.06.10
I really love the battery life that I get with myn's warm 2.2, and I could live with it, but I was really wanting to try GB. I thought I read somewhere that after I update the radios then I can't go back. So...
1) assuming I've got a nandroid of what I have now, can I just start flashing away with GB from xHausx and the newest radios
2) If I decide that I don't like the new setup, if i restore my nandroid, will the updated radios remain, and if they do can I go back to the old ones I had somehow?
Thanks a ton, and thanks will be given!

here is a link you may want to read http://forum.xda-developers.com/showthread.php?t=790427 . but radios i believe you can flash older ones. its hboots that i think(not 100% on that) you can not go backward on. as for nand look at the link,i believe unless the rom you flash has radios those stay the same when going back. if you like warm 2.2 rls5 then maybe you should try synergy(myn is one of the devs on that ) is a 2.1 with 3.0 gb rom. hope some of my rambling helps you out

[Q] Returning from the Dead

Hello Supersonic Community,
I come to you in my time of need, I have spend the last 3 days at work trying to downgrade an Evo 4g to 2.1. from 2.2.
Initially I ran unrEVOked3 reflash package as from what I read it would probably be the easiest place to start from an unrooted 2.2.
Once I was rooted on 2.2 I followed the guide from here
and used the RUU/Zip files from here
I currently have the phone in a state where it will only load into the bootloader and I do have a working amon ra recovery.
When I try flashing the RUU's PC36img.zip file from hboot I see that it "checks" the zip file however I am not prompted to run the update.
and when trying to run the RUU zip file from recover it says there is not update script.
My main question is if anyone knows why I am not prompted for the update from Hboot or if its possible to flash from recovery back to stock 2.1
I come from a Nexus S and HTC Desire background and have a bit of knowledge just kinda stumped right now on this one. I am currently trying different SD cards for the hboot flash as I have read that it can be a bit finicky.
Thanks in advance for any help.

It all goes back to the Hboot version you have. I think it's anything over 2.10 you can't downgrade.
I think your best bet is to just flash a stock/Rooted 2.1 ROM or a custom Froyo ROM

Well my HBoot is .79 so I hopefully can recover to 2.1.
I basically can't have a rooted phone, I work in mobile QA and we can't test on devices that are rooted. Which I know is a bit retarded but thats how it works for us right now.
If I flash a stock 2.1 rooted Rom I should be able to unroot.... at the very least uninstalled su and my boss won't know hehe
Thanks for your reply.

Did your phone come with that hboot? If your hboot and radio match the ruu you are trying to flash, then it should be good to go. If you r s-off while trying, even better. Do you have 20k or 40k block sizes?

**********HBOOT VERSION IS .79 *************** TYPO IN OP
That would be the Hboot it came with these are testing devices at my work. they are ALL STOCK unless i personally change it as no one else here handles the android phones.
I am unsure of the 20/40 k block sizes you are referring too do you mean on my sd card?

So i have successfully flash a rooted 2.1 stock rom and am trying to uninstall super user. If anyone has any tips on this let me know
