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.

First of all forgive me if this question as been asked a million times but to be honest I'm finding the Dream section a mess.
Now onto my question.... I've rooted my G1 and I'm currently running JF 1.51 with hero skin, now I'm I correct that I will always be rooted as long as I stick to custom roms?
The other thing is when I go into recovery mode I get a message at the top of the screen something like "Unable to find /system/command/recovery.cmd" am I correct that means I'm unable to proform backups? which is no big deal for me.
Finally whats the deal with this new spl, do I really need it to run a hero ported rom? I only ask because in all my years flashing windows phones the spl is something you should flash once and leave alone to avoid errors that can brick your phone.
Yes you will always be rooted. Not really sure on the recovery thing...You might want to try to fix that by flashing another recovery image. Yes you need the new spl to run the hero ROM since its HUGE

Thanks for the fast reply, as for the recovery thing like I said I would never back anything up and restore it anyway (I've always started afresh with every new rom)
Now going back to the spl thing.... Ive already updated my radio to the latest so when I do finally go for a hero rom and do flash my spl is the new spl a custom one which will allow me to reflash back down to a non-hero rom? or do I have to go back to the orginal hardspl first?
The new SPL was released by haykuro and it allows you to have about 30 more mb of space on your system partition. It still allows you to flash non-hero ROMs as well as hero ROMs. Sorry for the slow response >.>
Thanks alritewhadeva everything is clearer now.
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

Might wanna use 4.2.5. ROM at the moment though, users have been posting issues on the newest version, go here: http://www.cyanogenmod.com/download/rom/update-cm-4.2.5-signed.zip

thanks for your advise! sold my phone with cyanogen
Nice!!! Im glad I was able to help... get another G1 or other android phone.

Hello this is my first post here as I'm having trouble with my G1
first of all last night I tried to upgrade from donut to eclair but I got nowhere, I just had a bricked phone wouldn't go past t-mobile and g1 logo. Today I fixed it but it will only run the RC7 & RC8 updates and not go any higher as there is always a failure or no verification.
I was wondering if you guys can help me get from 1.1 to 1.6 or 2.0. and root as that didn't work either
Thanks
I'd suggest starting with the root since you're already on a cupcake build.
Then you can flash you SPL and Radio and head to a good rom. The thing about 2.0 roms are that you need the danger, hard or hayruki spl to flash because your phone partition isn't large enough to hold the rom.

Hey guys, I have an old rooted G1 (FW 1.6, CM Mod 4.2.11.1) and I need to get it back to Vanilla like today in order to sell it to my friend tomorrow before he buys from someone else. I use my N1 now and it's not rooted so I forgot how to do things on my G1 and stuff, mod-wise. So can anyone point me in the right direction as to how to get my G1 back to normal? I also want to wipe it so none of my information and stuff remains, just as if it were brand new.
Thanks!

I've never done it, but I would guess you would need a stock rom.
Try this link, and maybe the unlockr.com
http://code.google.com/p/android-roms/wiki/Unroot
Be sure to read the comments because some people had problems. It's a bit ominous that there is a link to unbrick your phone.

You can flash the dreamimg.nbh to the g1 to bring it back on to stock and it will remove every setting on it. It will be like a new phone from factory. It will be on Android 1.1, but the OTA will hit soon to upgrade it to 1.6.
Here is the thread..Unroot Phone
DO NOT write any stupid NBH files.
Ensure that the SPL is version 1.33.2003 and the RADIO is version 2.22.23.02.
If not, write them using FASTBOOT. If the current SPL is a 0.95 version, first write the 1.33.2003 SPL via RECOVERY, then fastboot flash the radio.
Next: Go to developer.htc.com/adp.html and download the recovery image. Write it from recovery.
Wipe userdata and cache.
This will leave the phone is a STOCK/OEM condition with root available to ADVANCED users, and with a full proper engineering bootloader which will only be noticed by advanced users. No sense being a jackass and locking the thing out from the buyer.
Thanks guys.
What do you mean by "do not write any NBH" files. Will the link that G1Sanju posted work lbcoder? I remember back then we would have flash the old .nbh and make sure the Radio (and SPL?) were the same? And what exactly do you mean by write?

Hey, Thanks man...I never thought of this one....Ya this will also achieve the purpose, We flashed this recovery for CM4...but there were some issues regarding T-mobile specific applications as the model number was for dev phone rather then T-Mobile G1, I don't know how its right now..
Hmm, so what shall I do then?
Btw, the spacebar on the keyboard only works like half the time. I don't even know why.. so entering commands in the Terminal or whatever would be kind of difficult. Would I need to do that? haha

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.
