[Q] Downgrade 2.3.4 to 2.2 or earlier - G1 Q&A, Help & Troubleshooting

hello. new to the forum. i've scoured the net for solutions but i haven't found anyt that applied directly to my situation and came here for help.
first off, im a bit new to the android world--being an iphone geek my whole life so here goes.
ive got a htc dream (g1) rooted running 2.3.4
Mod Version is COS-DS i wanted to test out. But i dont care for it and wanted to go back to an earlier version, maybe cyanogen 6.1 but that runs 2.2
i was wondering if it would be as simple as grabbing the 6.1 ROM and flashing it onto my phone from my sd card
my HBOOT version is 1.33.0013d
my Radio version is 2.22.27.08
I had 6.1 on my sd card and flashed the rom because i saw a video of someone else who had the same radio/hboot version as I and it was working so i thought it would be that simple, but when i flashed it i was caught in a bootloop at the G1 Tmobile screen.
Luckily i was able to recover, (i backed up my info using the Clockwork Recovery from Rom Manager)
Any ideas? Any are welcome. And once again my apologies for my blazing noobishness.

CM 6.1 is bootlooping due to your radio/SPL combination. You need a special kernel for this, which needs to be flashed on top on CM 6.1. Terry's kernel from the ezGingerbread thread should worl, I guess.
You can also downgrade your radio/SPL, but I do not suggest so, because you will lose the additional memory provided by that combination.

How to revert back to original rom.

Hi i have a htc dream and rooted/flashed it to tmobile g1 with a hero rom. Now i'm selling the phone and would like to revert it back to my default rom as in how it was when i brought the phone.
how should i do about it?
Thanks!
I am guessing sense you have a hero rom you have Haykuro's spl, if you need to revert back to the orginal rom just go over to this thread http://forum.xda-developers.com/showthread.php?t=592662 , jonzina has the step's to follow, just follow to the T and you will be fine.
there is also a walkthrough at www.cyanogenmod.com in the wiki
pretty simple process. flash the rc29 dream.nbh and wait for an OTA update to get you up to date pretty much. just follow the steps in the wiki.
the problem is, mine is a singtel set, its not a t-mobile g1, its a htc dream though now it becomes g1 after rooting and rom. i want to revert back to before. can i still use the dream.nbh?
Just a heads up, if you have the 1.33.2005 SPL required for Hero ROMs and you use DREAIMG.NHB to downgrade, you will brick.
To avoid that:
1) Wipe then flash a ROM that does *not* require 1.33.2005, (eg Cyanogen Mod)
2) Flash the stock SPL as update.zip
i'm so confused now =/
edit:how do i check spl ver?
With the phone powered off, press and hold the camera button and power, which will bring you into bootloader mode...if you were running a hero rom, you should have 3 androids on skateboards at the bottom of the screen (1.33.2005 SPL)...if so, do what AdrianK said
ok! but i still can use the DREAIMG.NHB from t-mobile? as mine is the not the t-mobile set, mine is a singtel htc dream. able to use the same method?
Some people WANT custom roms on their phone and are scared to do it themselves. Im recommending Cyanogens rom because its so fast and stable. If I were you I would post it as is, that way it stands out from the 100+ other G1 sellers.
If you don't see the response you were looking for just update it and reinstall the stock one.... just my 2 cents.
haha..how you know i'm selling.. you are right maybe i should try what you suggested. anyway how do i change roms? my current hero rom is the my one and only one.. likey to be out dated and laggy. last time follow guide to root and flash, what about updating? just dl rom and flash? haha

This kinda gave it away.. lol. I also had a hero rom and hated it because it was soooo slow. Just follow the directions here and it will boot up and work 100%

Only CM works on G1 and MT3G

Alright well first off I've looked all over XDA for an answer if theres is one out there a Mod can remove this post. I'm not new to this at all I have been flashing roms since the Dream was released, just the other day i was thinking about trying out a new from King's new Legend coming from CM 4.2.15.1 as usual i wiped everything reformatted my SD partitions and installed the Legend rom, now for some reason i cannot get past the G1 screen on that or any other rom there is out EXCEPT CM 4.2.15 I attempted the same thing on my 32B MT and get the same problem it will not go past the MT green screen has anyone had this issue or would anyone be able to tell me whats going on I've tried everything i could think of and nothing works. Thanks for any help people!
theres a lot of other roms that require a different SPL than CM does. make sure you have the correct one installed. also, make sure to wipe before flashing.
I have kept that in mind and yes I have wiped before every flash I once again just now tried the CanNNoN202 rom correct SPL and all also running the latest radio still no go on either the MT3G or G1
wut does it say in bootloader screen ?

So...
You want to intentionally go OUT OF YOUR WAY to make it difficult for the buyer to be able to do what they want with it?
LEAVE AN ENGINEERING SPL ON IT!!!!
Install SPL version 1.33.2003 -- this is a full engineering SPL with original partition layout.
Then you head over to developer.htc.com/adp.html and grab the newest ADP1 firmware files. Flash that.
The thing will be root-via-adb and fastboot, so the new user will not have to do any weird hacks to get what he wants from the thing. At the same time, he will have a bone stock ROM on it that functions predictably.

You have cyanogen recovery 1.4 you say?
First:
install 1.33.2003 (very important -- ends in a THREE) SPL. Search the forum for it, should be around.
Second:
install 2.22.19.26 or 2.22.23.02 radio (.19.26 is available at developer.htc.com/adp.html).
Third: install a newer recovery image. Check the dev forum.
Fourth: install any ROM you like. You can install the bone stock ADP1 system image (like tmobile stock, but has root), if you want to try CM6, you should look in the dev forum for firerat's MTD PARTITION HACK THREAD. Hell, it would do you good anyway.
Thanks! Time to do some reading and get this resolved.

Need help flashing roms to G1

I have been trying to flash the CM7 Rom to my G1 and continue to get the same error messages... I tried uploading a pic but the app wouldn't let me, so I will try and get the pic posted asap

what is your radio/spl?
also have you flashed many other roms before?
Please using following combination for Radio and SPL. Also note, flash radio first and then SPL otherwise G1 will not boot. Also make sure you have Clockworkmod recovery for CM7. This recovery helps for smooth flashing for CM7.
update_2.22.28.25_S - Radio
hboot0013d-signed - SPL

OK, this might be sorta a strange question, but this looks to be the best place to ask it.
Will the Dream be bootable if you flash only the Radio and SPL, leaving untouched the stock Android 1.6?
While I am a Linux geek, I am new to android and prefer to take things one step at a time. That explains why I have a Rooted dream with Amon RA with the stock 1.6 backed up with nandroid.

never tried, theoretically it should be as if you did a factory reset and you would just use your recovery to replace anything lost. but if you want to be safe maybe someone who has will chime in.
besides the point go ahead and flash a new rom, even if you stick with 1.6 firmware the developers have come out with much superior roms over the stock android. if you want only 1.6 try super d or super csdi
ok so i decided to test this out, updating a g1 to the 2708+ radio/spl and not flashing a new rom -------- stuck on g1 boot screen, hit call+menu+power then hit home to reboot to recovery, reflashed rom and gapps, rebooted, now everything is good as can be, so to answer your question --- yes it appears you need to flash a rom after you update your radio/spl
