[HELP] Revert to 0.33.0012 SPL

Hi all,
I foolishly flashed the Korean FRF91 onto my N1 and now I have SPL 0.35.0017 instead of the normal 0.33.0012 version.
To downgrade, I have tried:
- repacking the 0.33.0012 HBOOT into an update.zip (Looks like it worked, but it didn't)
- Flashing 0.33.0012 through FASTBOOT (Verification failed)
- Applying an older Google update (Main version is older)
Any ideas?
Thanks!

But now my N1 has an HTC logo on the screen for FASTBOOT.

Probably because the link given by baseballkyle is in the "HTC Desire" section of the modaco forum, not nexus one.

Yes,
I would also appreciate an explanation on how you did it.
I tried it but it didn't work for me.
The hboot.img doesn't work. If I try a zip version it seems that the device accepts it and flash it but i keep having the wrong version installed.
Could you explain how you made the mtd0.img (with which numbers) and provide a link to the hboot version that worked for you?

PLs Help Also
Pls tell us also how u did it, thanks..

I have posted instructions here.

Great!!!
The key was applying the hboot file through the PASSIMG.ZIP and not just alone.
Fantastic.
Thanks a lot

nexus Hboot
What happen if I install the korean hboot. Because everybody is complaining about it. They want to return back to stock Hboot.

Though that hboot is newer currently all the signed firmwares (original ones, CM6, and whoever provide signed builds) check that the hboot version installed in the phone is 0.33.2012.
If you don't have that one then you will not be able to install any of this firmwares directly.
With some manual work you can make it happened but forget about OTA updates (stock OTA updates, CM-updater OTA updates, Rom Manager OTA updates).
If you don't care about that then you are fine.

help
i cant install any ota update can someone please help i went to erd 79 hoping that would fix everything

So what is the correct hboot version to use? I currently have 0.33.0012

how do i go back to frf91 from frg33?

I flashed 33 and my phone is stock. I need paid apps plus this build is bugging out on me alot. Stuff freezes, its just a bad build. How do I undo this without rooting?

Pretty sure you have to root.

If its like FRF91. Then it wont let you downgrade because it sees FRF91 as an "old version."

Download ere27 as passimg.zip. place in your sdcard root. Boot into recovery. Restore. Let it do its work. Put frf91 into sd card. Boot into recovery and load from zip. Ta da. You are on Frf 91

Or, if you want a shorter and more correct route:
Nexus One Wiki, "Restore", PASSIMG.ZIP method, use FRF91 complete stock image found in one of the threads in Q&A from the last day (or Google).
Don't use FRF91 update, since it's only an update - it's not a complete image.

whatever. Just use a passimg.zip to clean out all the crap. its basically the "do-over" method. Think etch-a-sketch flip and shake.

i tried passimg from http://forum.xda-developers.com/showthread.php?t=717870
it said failure because it was an older version. If i find that ere one will it let me do it? i dont mind going way back and working my way back to froyo, but i dont think i can passimg anything since its considered "older"

search the forum for how to downgrade your hboot- it exists just search for the thread

Thank you. Looks like ill have to root for it which im sure ill find if i search how to root 33 so ill wait for a while to see if something else comes up but at least I know there's a way

There is no other way but to root.
Since you're erasing the system you're rooting anyway, why do you care?
The full guide is now in the Wiki, including reverting HBOOT for those that need it.

i dont know, i did 1 click root a few times but every rom i tried- cyan, eno, modac, whatever were great but there was always some bug or something that was annoying enough that i just wanted stock instead. So i dont know how much i like the idea of permanent root, but theres probably a stock rom i can use so its not the end of the world. SDK/Terminal i did all that crap with my g1, personally i found it to be more of a hassle than it was worth. But not having protected apps is not going to cut it so ill cave soon im sure

Again, maybe this time it'll be understood:
There is no "permanent root". The only "permanent" thing is unlocking the bootloader, which you don't have to do - the guide doesn't require it. The system you root will be erased in the PASSIMG method and replaced with a completely stock system of your choice. So, what's exactly stopping you from rooting?

the only way to go back from FRG33 is to unlock the bootloader at this stage, the PASSIMG method does not work

When you revert HBOOT, it should work fine. Just the same as it works with Korean FRF91 version, which also has a new HBOOT. People in the FRG33 thread don't know it?

Why people can't understand?At this moment,if you've flashed stock FRG33 rom,using PASSIMG method,you can't root anymore!The only method to roll back to FRF91 is to unlock your bootloader,which is permanent and can't be un-done!
Cheers

Did you see that?

Or is it the only report? (in that case, the guy probably didn't try to run root).
Anyway, being unable to root makes you unable to flash PASSIMG of anything with bootloader lower than 0.35 - but did anyone try PASSIMG with Korean FRF91? It has the same HBOOT as FRG33, so it shouldn't be reported "older".

[HOW-TO] Revert HBOOT 0.35.0017 to 0.33.0012
I CAN'T RELOCK THE BOOTLOADER!!!
This only reverts your SPL/HBOOT back to 0.33.0012 after you've installed the Korean FRF91 files and ended up stuck with 0.35.0017 SPL.
Thanks to the guys in the Desire forums and help from the Nexus Q&A, I have reverted my phone to the original HBOOT so I can apply custom roms again.
First you need to root the Korean FRF91 that's on your phone using Paul's instructions for superboot FRF83.
If you are rooted already, skip this step.
http://android.modaco.com/content/go...the-nexus-one/
Code:
How to use Superboot - Windows, Linux and OSX
- Download the Superboot zip file above and extract to a directory
- Put your device in bootloader mode - Turn off the phone then press and hold the trackball to enter the bootloader
- WINDOWS - double click 'install-superboot-windows.bat'
- MAC - Open a terminal window to the directory containing the files, and type 'chmod +x install-superboot-mac.sh' followed by './install-superboot-mac.sh'
- LINUX - Open a terminal window to the directory containing the files, and type 'chmod +x install-superboot-linux.sh' followed by './install-superboot-linux.sh'
Note: If you are using a retail Nexus One, you may need to unlock the bootloader first, as detailed here.

Ok, let's make some order:
1) PASSIMG can flash versions with the same or higher HBOOT version - to check: will the same version flash? I believe so.
The official FRF91 has HBOOT 0.33.0012, the Korean FRF91 has 0.35.0017, and I suppose the FRG33 also has 0.35.0017 - correct?
2) Rooting isn't possible on FRG33 yet. 1 report doesn't count.
So, looking at this:
Using PASSIMG with the Korean FRF91 (complete with HBOOT 0.35.0017) will work over FRG33, if the HBOOT is indeed the same version.
Korean FRF91 is rootable.
Rooting Korean FRF91 allows to downgrade HBOOT, which in order allows to use PASSIMG method to flash official FRF91 with older HBOOT.
So, did anyone try PASSIMG with Korean FRF91?

[Q] What is HBOOT and why should I update it?

Hello,
I have some question regarding HBOOT:
What is HBOOT?
What is the difference between Bootloader and HBOOT?
Why should I upgrade or why I shouldn't?
If I upgraded it is it easy to downgrade?
Mine is HBOOT-0.33.0012 and there is a version HBOOT-0.35.0017
Because some ROMs requires the newer version and I saw some article warn not to update!!
Thank you and Regards.

1. Hboot is the boot loader.
2. See above.
3. Upgrading to the new Hboot supposedly gives you some small benefits such as better reliability in certain cases. It is also supposedly required by gingerbread. Most of the AOSP builds of gingerbread don't require the updated Hboot, but the initial builds required it. If you upgrade to the new hboot, I believe you loose the ability to flash images by the PASSIMG method (renaming a signed image to passimg.zip). The new Hboot was rolled out as an update along with the FRG83D OTA. I see no real reason to upgrade it or downgrade it. Messing with it could be dangerous.
4. http://forum.xda-developers.com/showthread.php?t=726258 I wouldn't say it is easy, but it is possible to downgrade. Not sure why you would want to. Downgrading an SLDC Nexus will brick it.

The warning to not update was due to some ROMs not working on .35 as the update script was checking for .33, however this was months ago and is no longer an issue.

Thank you guys for the reply, I already upgrade it to use a gingerbread rom, I think I'm going to stick with it for awhile. If I needed urgent to downgrade it I will try it but not now.

Don't worry, you'll never need to downgrade it.

[Q] Flashing: Main Version is older

Hey guys
I'm preparing my N1 for 2.3.3 and since I had it repaired I'm now stuck with some weird Vodafone(?)-FW.
2.2.1
2.6.32.9-g6624e39htc-kernel [ät] and18-2
5.12.00.08
HBOOT 35.0017
Anyways, I tried to flash it back to stock 2.2.1 but when I apply the PASSIMG.zip it says "Main version is older. Update failed!"
Is there a workaround?
I read something about downgrading HBOOT to a lower version?
Thanks!

If FRG33 isn't flashing by PASSIMG method - then you can't use it. If you exercise your abilities to search the forum, you'll find a thread where people were trying to circumvent that - updating from Eclair to Froyo (just like now) - and those attempts failed.
If you have SLCD phone - and if recently repaired, you definitely have it - downgrading HBOOT will leave you with a nice brick.
Root your phone, install custom recovery, flash whatever you want from there.

I'll try that. Thank you very much.

Now running on Cyanogen.
Thanks again!

You're welcome

[Q] How to dowgrade from Gingerbread Radio to Froyo Radio?

I have an Incredible S running froyo. I used the alpha method to S-Off then I rooted the phone. Since I was rooted I decided to add a rooted gingerbread rom. I extracted the rom.zip from the gingerbread RUU for my phone and ran the rom.zip through the Rom Kitchen. Only option I picked was to root. (Kept it simple) The rom wouldn't flash. Kept getting stuck on the slash screen so I used recovery and went back to my working froyo backup. Then I decided to download CM7 rom and flash it. The same thing stuck on CM7 splash screen. Used recovery and went back to my working froyo backup. I figured maybe I need a gingerbread radio for the roms to boot. I installed eng hboot and flashed the gingerbread radio for my phone. I tried installing both my rom and the cm7 rom with no luck. Both roms get stuck on flash screen. So I used recovery to go back to my working froyo backup. Now I'm stuck with a Froyo rom and a Gingerbread radio.(No sound on calls) I tried flashing the original froyo radio but after flashing the froyo radio my phones go into a boot loop with the HTC splash screen. So I flash the gingerbread radio and phone boots up and works again except no sound on the calls because of the gingerbread radio.
So my question. How do I downgrade from a gingerbread radio to a froyo radio? The flash methods I used to originally flash my radio do not work.

Glad to know I'm not the only one that bricked it like that xD... I don't think you can
downgrade... I am thinking about maybe trying to flash Optus through fastboot, but I'm unsure if that will work... But another option is to use a ROM like Revolution or CM7 which are gingerbread.

Same here bro!!!
Same here bros
I got my IS with foryo 2.2, was working fine. I thought to update to gingerbread but was not aware then i will not be able to downgrade or S-OFF.
I just got Gingerbread OTA update of 83.3MB, just updated and now its working fine but
no S-OFF, no customer recovery, no Custom roms
dieing to Downgrade so that i can do S-OFF for rooting and custom rom installation
ANY BODY HELP!!!!!!!!!!!!!!!!

First try the AlphaRevX method to S-Off. From there you should be able to install custom recovery, root, and install custom roms. If you can not S-Off with the AlphaRevX method then install a gingerbread rom on your phone from another region through gold card method then use the AlphaRevX method to S-Off. (Most people been using the Australia Optus Rom)

Yeah that is the method I used. I thought with eng hboot I had the flexability to bounce between radios but for what ever reason once you go to a gingerbread you can't go back to a froyo radio.
