Downgrade radio - G1 Q&A, Help & Troubleshooting

Hi,
I seem to have some issues delievering SMS under the new radio (I assume it to be the cause).
I'm currently using both SPL and Radio from Haykuro (that I flashed in order to try on Hero roms), but, having the above in account, I'd like to return to stock radio (version 1.smth).
So, taking teh brick factor into account I was considering doing the following:
1) Flash DangerSPL
2) Flash Stock Radio
Is the procedure safe/correct/in correct order?
Where can I get the stock radio?

DO NOT flash the danger spl and downgrade radio, youll brick for sure. Id just try a reflash of the radio, rom or both first.

Quick SPL and Radio question

Wether or not I have a rooted G1, should I always try to have the latest radio and SPL, even if the ROM doesn't require it?

If you don't have root you can't flash your ROM, radio or SPL. AFAIK There has only been the android 1.1 and 1.5 Radios, so they don't come along too often. If you're on a 1.1 ROM then you should be on the 1.1 radio, same with 1.5, you should be on the 1.5 Radio. SPL is your choice depending on what you want. I use Hayuro's because it supports all ROMs, but some prefer Hard SPL. If your ROM doesn't need a different SPL, wether you want to install it is your choice.

Radio upgrade

I just had a quick question, Can you just use the new radio upgrade without the danger spl, or do you HAVE to flash the spl with the radio.....
does the hero radio offer any advantages over the cupcake radio?
You do not need to use the danger spl in order to use the new radio image, the radio image is just the newest radio software, you could get better service with or you might not so flash it see how it works for you, I always download the newest for better service for me
You can flash to the newest radio whenever, the trouble comes when people have the danger spl and flash backwards.

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.

Question about re-flashing 2.22.19.26I radio and Haykuro's DangerSPL

I have the latest 2.22.19.26I radio and Haykuro's DangerSPL.
I want to re-flash both of these.
1) Is it safe to flash the radio and then the SPL?
2) If I decide to go back to HardSPL, will it be safe to just flash the HardSPL while the 2.22.19.26I radio is already installed?
I want to make sure my Android won't turn into a doorstop

why don't you want the haykuro spl?
Ok, maybe I won't go back to the HardSPL. All Hero ROMs require Haykuro's SPL and even some AOSP ROMs like SuperD need it too.
I just want to know if my phone will brick or not, because I've done simple stuff like this before but ended up with more problems (even bricks) because no one cared to mention there was a danger.
@hiddengopher
lol at your signature xD
so can anyone answer this i was wondering if you could go back to hardspl too?
You phone will be fine... and .26I is not a latest radio.

dreaimg.nbh+death spl= safe?... help, bout to flash

I have to go back to full stock for insurance purposes, it wont pick up any cell service. The dreaimg.nbh is a full img if i remeber correctly. That being recovery, system, RADIO, and spl, right. If thats the case i SHOULD be fine right? I not 100% sure about the spl being in it, so i wanted to make sure. Thanks!
If you're talking about the RC29 for TMo G1, then yeah that one has everything in it. When I downgraded I fastboot flashed the original SPL first in case something happened during the process. That way I could be fairly certain I wouldn't wind up with a hard brick.

I do not know exactly, what dreaimg.nbh contains, but I boubt it will not contain a SPL, so flashing it may brick your phone. For security reasons I would first flash a SPL which is compatibe to a 1.x radio, i.e. stock-spl or 1.33.2003.

It contains the following...
-Stock Radio
-Stock SPL .blahblah
-1.1 Android(RC29)
Dont worry, ive flashed the nbh 2+ times just for testing purposes while having the Haykuro/Danger SPL & 26I/new radio
Just flashed DREAIMG.nbh over a 2.22.23.02 radio and Haykuro SPL - everything went smooth as DREAIMG.nbh contains stock radio and SPL. You can downgrade without fear.
