Alternate way to revert to stock firmware without waiting for update
Hello,
This is my first post. I have been using an alternate way that I figured out to return to stock. This also works when you try to install an official update and it rejects the package due to invalid keys or device checks. You MUST already have root on your phone for this to work.

1) download official firmware image (whatever version you want)
2) extract recovery image from package to root of SD card
3) rename downloaded package to update.zip and place in root of SD card
3) reflash recovery image from terminal on rooted g1

mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd sdcard flash_image recovery recovery.img
cat recovery.img > /system/recovery.img

4) Restart phone in recovery mode and proceed with update
5)Profit! Well, stock g1 without having to flash to RC29 and wait for an update.

I feel this is a more straightfoward way to flash back to stock. YMMV.

so all of you that messed something up on your phone and need to get it back into warranty this is how, FOLLOW THESE STEPS

1. get the original SPL for your phone, go to the SPL thread at the top
2. rename it to update.zip and flash it to your phone
3. download the DREAIMG.nbh from the thread where you rooted your phone
4. place DREAIMG.nbh on the root of your SD card and start phone in bootloader(camera+power)
5. hit power to start the update
6. hit action(trackball down) and your phone will reboot
7. YOU NOW HAVE STOCK FIRMWARE, it will update on it's own in a little bit

mods can we please make this a sticky?? i understand we have a lot of stickies already but this one thread takes up less space than 30 threads all asking how to do it. thanks

where the hell is the SPL file,to unroot my phone..i had the rc33 n i rooted it to rc29..n now i need to take it back to t-mobile,,so how the hell do i put it back to stock..somebody help this new guy..lol

I flashed back to stock RC29 however I have not received the OTA update as of yet(8+hours) and there is no option in the Settings menu to check for updates. I downloaded Any Cut however I'm not sure what I need to enter into the fields in the make your own shortcut option to perform the check for updates function.

Is this indeed stock tmobile rc29?
The About menu in my phone states the following:

Kernel Version
2.6.25-01843-gfea26b0
android-build@ap27 #6

Build Number
Kila-user 1.0 TC4-RC29 115247

SPL is in the SPL thread

DREAIMG.nbh is in the how to root hack flash your G1 thread

if you are in US and using RC3X and the update is taking too long for your liking the hit menu>settings>about phone there is either and option there or in status to look for system updates. if you are in UK then the options are probably the same but i do not know for sure.

May have already been discussed, but why would you want to unroot your phone?!

for multiple reasons, first for warranty exchange, second for getting the OTA update so we can get the freaking t-mo US 1.5 update URL
