Un-root Rogers G1 and revert to stock - G1 Q&A, Help & Troubleshooting

I followed haykuro's guide to try and root my Rogers G1 but I'm having issues missing my google apps. I want to revert my phone to stock and then follow cyanogenmod's wiki guide for my phone.
What steps should I follow to revert my phone from cyanogenmod ROM, radio 2.22.19.26I, HBOOT 1.33.2005 (DREAM21000) to bone stock?
I searched to see if someone had posted a guide for this but couldn't find anything.

Yes, I've tried both the HTC recovery and the defanged image with the same results. I have a thread here http://forum.xda-developers.com/showthread.php?t=612244 that is detailing my effort to get my google apps back so if you have any ideas please post there.

Are you having app issues? Why do you want to revert to stock?

Question about upgrading SPL

Hi, I currently have the 3.22.20.17 radio on my phone. If I follow the guide to root the Rogers Dream I will have to upgrade to haykuro's SPL with this radio. I have read that people have bricked their phones if they don't have the correct radio when upgrading the SPL. Am I ok to do this or could I brick my phone?
Thanks
If you goto haykuro's thres "rogers, here's your real root" the first line has a link to somones guide to flashing the spl. Follow that and you should be good.
Thanks for the reply. I was just wondering if it was correct that I am supposed to be starting out with the 3.22.20.17 radio for this guide.

Actually it's 2.22.19.26I
So I am supposed to have the 2.22.19.26I radio already? Remember that I have a Canadian Rogers Dream.

Follow what Haykuro's thread says (Rogers=probably not the 2.22.19.26I, you may brick your phone if you try the regular G1 root SPL method) . If you want to be safe, you can reflash the radio that haykuro posted
I'm sorry, I should have asked if the 3.22.20.17 radio is compatible with haykuro's latest SPL.
No it is not. You need to follow the guide exactly, I believe that you the stock Rogers radio. So just follow it and you should be set.
That guide gets you to flash the SPL before the radio and that SPL isn't compatible with my radio? Won't that brick it?

The radio's for rogers are completely different from the G1's
You may want to try and PM Haykuro because I do not see a clear cut answer
I sent him a PM but I haven't recieved a reply yet.
Could someone that has rooted their Roger's Dream help me out with this?
Can someone please tell me if I need to upgrade my radio on my Roger's phone before I start following the guide or will it be fine? I am asking because the first thing guide says to do is upgrade the SPL. I just want to be really sure that having the 3.22.20.17 radio and haykuro's SPL together won't brick my phone.

Rooted Rogers Dream help

hello,
just looking for a little guidance:
I've rooted my Rogers Dream based on the guide here http://forum.xda-developers.com/showthread.php?t=532419&highlight=guide+root+rogers.
From Haykuros thread http://forum.xda-developers.com/showthread.php?t=544654&highlight=Rogers+real+root, i have two questions
1) do i have SPL 1.33.2005 from the original root?
2) which step of Haykuro's guide to I continue from? or this guide? http://forum.xda-developers.com/showpost.php?p=4280573&postcount=130
Thanks

To check what spl you have power on your phone by power + camera and it will tell you.
thanks! i'll look that up when i get a chance
i hate rebooting the phone, then i have to run market enabler again, reset the carrier to Rogers, etc
so once i have verified the SPL, i should be able to continue using haykuro's steps? will it contradict what how i got my root access from another guide?
I had 1.33.2005 already on my phone, so I skipped that step in Haykuro's root process and it went flawlessly.

un root a root ?

is there anyway at all that you can unroot a rooted phone without knowing.
if you can, what would you have to do to do it ?

RC29 will downgrade the SPL to the original (and radio, too).

I heard that you shouldn't download the radio(due to brick), but is it ok to downgrade the radio using the RC29 img?

Basically, if you have the 1.33.2005 SPL and you don't have the 1.5 radio you'll brick. Be it flashing without the new radio or downgrading the radio after SPL flash. You can flash a different SPL (say, HardSPL) and it will go fine, but you must not downgrade the radio first.
The RC29 img basically wipes your entire nand and reflashes the stock SPL, installs the RC29 firmware and flashes the 1.1 radio image. What it will *not* so is reflash the splash_2 image (it might do flash_1) so if you have a custom splash image then use fastboot to fix that first.
That understanding was put together by reading pages upon pages of the brick thread before flashing 1.33.2005 (as I was scared poop-less of bricking) so hopefully it's all correct.

Rooting a HTC Dream without applying another ROM

I have a South African HTC Dream and did some research on this forum about rooting. I am more than happy with the phone's current ROM with the exception that it does not support WPA-Enterprise Wifi - in order for me to configure this, I would need to root the phone and will then be able to adjust wpa_supplicant.conf.
In all the tutorials I would have to downgrade the firmware (I have not been able to do this with any of the guides supplied - either normal RC7 downgrade, 1-click or Goldcard) in order to root the phone.
Is there any way I can root the phone without having to flash another ROM (i.e. retain the current HTC ROM and make adjustments to wpa_supplicant.conf)? Most ROMs provided are not based on HTC build, and I would loose ActiveSync. AFAIK there is no ROM available which provides ActiveSync AND HTC Mail.
My current phone info:

There are HTC based ROMs. The ROM from the Rogers Dream has exchange support, but before you flash the ROM you must flash the new radio then the SPL.

Thanks - I replaced my phone with another one (FW 1.1) and was able to flash. I installed Touchdown to overcome the Exchange problems - not ideal, but best choice now.

You're on 1.1?! I would strongly recommend flashing a Cyanogen ROM to get you back to 1.5.
I did update to latest Cyanogen rom. One question: I rooted the phone and am on latest Cyanogen. Only (minor) issue I have is that before the Cyanogen splash-screen comes on, I still see my mobile providers boot-logo (for about 10 seconds until the splash screen comes) - is there any way to change this?
I tried fastboot flash splash1, but get an error. As part of my rooting I did not flash SPL (i.e. HardSPL) but have cm-recovery - should I update SPL and if so which one (also, what is the risk of bricking?).
If replace SPL, do I need to update the radio again or reflesh Cyanogen?
As far as I know you wouldn't need to flash either again, HardSPL is known to be safe on all phones I believe. The only problems I've heard are with Haykuro's SPL. If you haven't flashed a new SPL that could be the issue, what is the error your getting when trying to change the splash?

It should be safe as long as it doesn't not require a specific radio. I have never heard of the radio version you have, but that's probably because you don't have a t-mobile G1. What carrier is it on? If it's unlocked, what was the original carrier? (the ones displayed on the boot screen).
I think Josh is right that it's safe for all Dream's, so you probably could go ahead and flash it, I'm not 100% sure. Just a quick not about flash SPL's and radios on cm-recovery, you have to physically press alt-s then home+back to reboot. Don't touch the trackball. That's only for SPLs and radios.
The hard spl is great, but if u want to run hero u will nees to flash haykuros spl. If u do flash haykuros spl make sure u flash the new radio image FIRST! OR U WILL BRICK! Have fun flashing away
Thanks. I applied SPL from here: http://forum.xda-developers.com/showthread.php?t=548924
And then fastboot worked: /fastboot-mac flash splash1 DOWNGRADE-SD/Boot_images/android.rgb565
Upgraded to latest Cyanogen 4.0.4 and have now an awesome phone - thanks to everyone for the help on this forum!

I had flashed ota-radio-2_22_19_26I (not sure what it was before). I did roughly document my steps on my blog if you are interested.

thanks. after seeing the radio you said you originally had in the first post i remembered that rogers has a radio that starts with a 3(then i searched and they are the same radio), then when i tried to download the root rogers package from that thread it kept timing out the download, so i was just curious as to radio you used. according to all the rogers root thread you have to flash the 1.33.2005 spl first before you can actually root, so basically i was trying to figure out if devices with that radio are immune to the bricking without 2.22.19.26I radio.

How to go back to original ROM?

I have G1 on custom ROM WG Built Y-2.6.
How to flash beack original ROM?
Thanks.
What's your SPL, and Radio? If your 2708+ with the new SPL. I don't think you could flash the original 1.6 ROM. But if your not, just search the Form's for Android 1.6 for HTC Dream or T-Mobile G1. Then flash it like any other ROM.
thanks for response.
radio is 0-1.22.12.29
HSPL 10.95.3000
is it possible to flash original rom?
From what I know yes.
Sent from my HTC Dream using XDA App
I need full instruction to downgrade. Cannot find any on forum.
Find unrooting guides. They often put you back to stock.
Oversimplified instructions:
1. Flash the stock .nbh file in hboot
Done
