revert to stock g1 from modded

i have a g1 that i installed Jesusfreaks 1.31 to and also flashed hardspl to it.. im having serious battery issues so i am going to return my phone for another one.. im trying to find a how-to on reversing everything i have done along with the stock rc30 image... can someone please point me at a tutorial or in the right direction...
i have googled it for the past 30 mins and have found nothing..
thanks

Download the G1Orig SPL here, flash that. Then download one of the revert update packages here and flash that. Remember to Alt+W to wipe the user and cache partitions too.
Edit: By the way are you having recurring serious battery charge loss or was it just one event?

You could flash the original bootloader (image is in the SPL thread) and then load the stock t-mobile rc29 onto your phone. Then take your phone to T-Mobile for warranty.
This way it just seems as though your phone never got the OTA rc30 update
I brought my phone in to ask a question about a clicking noise my phone had (the arm that the display moves on feels loose) when open. The guy behind the counter asked to see my phone and I was not thinking...he took it and noticed the clicking but said it was normal; he showed me his phone and a few display phones that did the same. Then he fired up "About phone" and suddenly became quite...he turned quite confused and told me that this was not a Dev phone. I played dumb and told him "I don't know, this is how it came from the store when I got it last month..." He then rebooted my phone to see both custom spash screens and the engineering boot loader...I wish I had a camera for the look on his face.
Oddly enough, both he and his manager were reluctant to give me my phone back.
So yeah, I recommend putting a stock rc29 on your phone before taking it in

i downloaded the origSPL and when i go to flash it with alt s it says verifying update package
no signature
verification faield
installation aborted
its renamed to update.zip and im assuming because i have done this before that i am doing it correctly .. any advice?

Did you already revert back to official Android? The SPL updaters are signed with test keys, so if you have already reverted to official Android then anything signed with test keys will fail to flash.

this is my build and kernel version..
would this be the updated rc30? i thought that i updated it correctly and i assume that i could not have flashed hard spl if i hadnt
Kernel version

When you enter recovery mode do you see JF's custom background or is it the standard recovery?

its JF's recovery screen.. im thinking to flash the test key recovery.img and then downgrade.. flash the new orig spl then the orig rc30.. witll that work?

If you're seeing JF's recovery screen then you already are running on test keys; there is no need to flash a different recovery.img

i have reformatted the sd card a bunch of times... only thing i can thnk of is that when i download the files from here to my mac it comes as a folder and then i zip them and rename them.. can this be the problem?

Comes as a folder? Sorry, I have no idea how macs work (or don't). You should not need to be zipping anything. If it worked before in the past i'm sure you got it working somehow. The MD5 of the file as it appears on the sdcard should be the identical to what I posted in the SPL sticky.

just use the RC29 NBH file and flash it from SD card. this will make it like it was out of the box.

but the spl will be the hardspl not the orig spl correct?

NBH file doesn't overwrite the SPL though, does it?

Just flash the Dream file here : http://forum.xda-developers.com/showthread.php?t=463779
It will go back to RC29 and back to that tri-color boot screen, then get the OTA RC30 here : http://forum.xda-developers.com/showthread.php?t=451090

ok.. i figured it out.. here was the problem.. on my mac when using safari in the preferences it has an option to auto open trusted files ..ex. pdf zips etc..
so it was unzipping the zips into folders.. then when i was re-zipping them it was messing it up.. i now have it working..
hope this helps others with this problem
and thanks to you guys for trying to help me trouble shoot it

There's your problem

that brings up the question...
to make thing simple for people.
Does anyone have the orignal G1 recovery.img image so for those who want to revert back to orignal firmware with ORIGNAL keys it would be nice.
for some people its better for them to know that thye are reversing their steps them.
what I know from all the threads above is just loading loading firmwares with test keys....
now how about the original recovery.img. Provding a reverse would be nice.
=)

Getting the original recovery.img is easy. Just download the original RC30/RC8 file from any mirror and open it up with your favorite archiving program. However in order to revert the SPL you would still need to be using test keys.

recovery I can do
the reverting of SPL..hell I dont know how to do that....

You think you BRICKED your phone...Post here!!!

oh no, oh no, what have i done??
I've created a little problem for myself. While at work I performed a wipe/restore on my phone. I have modified rc30 jf 1.3 and when my phone is booting up now I get stuck at the android screen. The green light near the ear piece comes on and a ringing can be heard from the speaker. I have tried to wipe again to no avail. Has anyone heard of this happening? Is it because I have a theme file on my sd card named update.zip? I know I can't be the only one to brick their phone!

Try reflashing JF 1.3. Did u create a backup?

I did not backup. I will reflash when I get home.

That should work. I had the same problem.

thanks, i need to hear that.

how would i go about using hard spl to bring it back from the dead?

Foolproof solution would be to use RC29 DREAIMG.NBH. More intricate solution is to fastboot flash your nand backups (provided you had the foresight to make backups in the first place).

What jashsu said. I nearly bricked my phone once but reflashing with RC29 was the quick and easy way of saving it.

i need help think that i am bricked
I was on 1.1 ADP JF with the mac 2.2 theme for 1.1 ADP i wanted to get back to the original theme so first i installed the restore theme thing on the fourms after this i have been stuck at the android screen when booting. i have tried to the wipe alt W but right now i am downloading the image file to get back to the original rc 30... can anyone help me out??? i really need to my phone tommorow and help would be much appreciated thank you

Assuming that you have the JF recovery utility, you should be able to copy the update.zip for RC30 to the sdcard (take the sd card out of the phone and copy update.zip to it), and apply the update from the JF recovery utility. You can get into the recovery utility by holding home+power when booting the G1. I hope this helps.

assuming if the above post don't get you up and running you will want to donwload the stock rc29 dreamimg file and copy that manually to your memory card and with the phone off. Hold down the camera button while turning on and you will get a grey screen the and should let you flash back to the original rc29 if you can't to an alt w whipe this would be the next thing I would recomend.

Just to clarify you said your phone is the adp - android developer phone, a phone that allows you to restore the phone to earlier states?
If this is the case you just need to grab a recovery image and reflash your phone by depressing camera on boot or using fastboot to restore your phone to an earlier backed up configuration.
If you don't have the developer phone, and infact have a rooted handset with a custom firmware such as JF your best bet would be as above to roll back to rc29 or rc07 if you're uk based using RC29 DREAMING.nbh -steps can be found here http://android-dls.com/wiki/index.php?title=Root_For_RC30
The downside is this will require you to reroot your phone. May i suggest in future if you do NOT have a developed phone you install Nandroid and do regular backups before playing with your phone -details here http://androidcommunity.com/forums/f28/nandroid-v2-0-full-nand-backup-and-restore-tool-9336/
Let us know hopw you get on and if we can offer any further assistance.

ok thanks guys
i installed rc 30's official image to my g1 by power+camera and everything is fine besides being unrooted i think i will root back to ADP again because of its advantages but if i am the flash a theme once again how do i get back to original theme because im sorry but i still dont understand the steps needed to do this from a ADP 1.1 jf build ty

You should have tried updating back to the 1.1 ADP JF version you were on first, would have saved you alot of time.

Hey! I assume for the purposes of this post and on accout of your having dev phon firmware you know how to use fast boot. if not go to http://androidcommunity.com/forums/f28/nandroid-v2-0-full-nand-backup-and-restore-tool-9336/
Anyway if you restart your phone with the home button depressed alt b makes a back up, use fastboot to flash this to your phone and restore it to an earlier state!!!!

Can the G1 officially be bricked?
I know you can screw up and update or 2...but with the PWR + Camera thing and the Home + PWR update method...is there a way to officially brick the G1? or is it relatively brick-proof?

I wouldn't think any phone is brick-proof. Then again, the G1 does seem more "mod" friendly than others.

Flash a corrupt SPL and you will have a brick really fast

Try it really quick and please post your results lol

I might be wrong, but I think as long as we don't mess with the boot loader, it should always be able to start with camera-power

[HOW TO] UNROOT, get phone to STOCK firmware

ok since there are 5 threads right now on the first page about how to do it and there shouldn't be, this is what you do, i will not link anything to anything because you should be able to find everything pretty easily(they are all stickies)
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:
NOTE: if you have flashed a custom splash screen to splash2 then you will need to erase that before step one with this code
plug phone into usb in fastboot mode
Code:
fastboot erase splash2
After that you will have only one splash screen and when you flash the .nbh you will be fine
1. Get the original SPL for your phone, get it here
2. Rename it to update.zip and copy it to your sd card. /sdcard
3. Download the DREAIMG.nbh from here.
4. Place DREAIMG.nbh on the root of your SD card. /sdcard
5. Go into your phones recovery. [Hold the home & power button]
6. Push Alt+S on your G1 to flash it with update.zip
7. After it does its thing, gettig back to your home screen.
4. Start phone in bootloader. [Hold camera+power button]
5. Hit power to start the update DO NOT INTERRUPT!! i can not stress this enough.
6. Click on the action button(track ball) and your phone will reboot.
7. YOU NOW HAVE STOCK FIRMWARE, it will update on it's own in a little bit, or *Settings>About phone>System Updates*

MODS PLEASE I'M BEGGING YOU TO STICKY THIS POST OR AT LEAST THIS ONE:

Mods sticky
Hey man you got my vote it was drivin me insane tryin to find this and thank you!!! Also, just to amke sure that it worked, what is it supposed to say on "About Phone". Thank you man

Just wanted to add one point - I followed this guide, but there's one bit that might not be obvious.
DREAIMG.nbh will restore your phone *mostly* to stock. There's one thing it won't change - the second splash image. If you've changed your splash images, you might want to restore them to stock separately before following these instructions.
Wouldn't be an issue for most users, but in my case the keyboard bit the dust and I had to do a return, and once I set it back to stock I couldn't re-root (and was left returning the phone with a custom second splash image).

i followed all of these steps and as it was applying the dreamimg rc29 for me it said failure... what do i try now? it seems that now my phone will only boot to the multi-colored screen and everytime i try to apply the update it fails about 3/4th of the way through... my phone doesnt work... any thoughts on how to fix this?

found the problem, sorry for my ignorance i didnt format the card completely so there were other files in the root and all i did was reformat and just copy the nbh file back over and it worked just fine sorry guys

one question...do i have to find the stock rc30 and rc33 to update also?? aren's there somethings required to update to cupcake? (like radio??)

you don't need to find the RC30 or RC33 files because when you have the stock RC29 your phone will update on it's own after a few hours. the only thing needed to upgrade to cupcake is the cupcake image. the radio is a choice and you ocan choose not to flash it. i still use the original radio that came on the phone with RC30 simply because i have been too lazy to get the latest radios

bump. good info

I rooted my fone for the first time today and played around. In the end I decided to unroot, because I need steeel and chompsms too much.
I went back to RC7 (my phone was previously RC9 before I rooted). How long should I expect to wait before my G1 auto-updates?
Thanks!

this should be a sticky... thanx

the greatest thing about the thread? well since making it i have only seen two people post that they need to unroot their phone and don'w know how. woo hoo

how long does it usually take to upgrade on its own? its been over 2 hours now and nothing..

its been over 24 hours since ii brought mine back to "stock" and i still havent received the update, what the f is going on? is this normal? sorry but im a newb.

same here I am back to the orignal RC29 but have not received any OTA like RC33???

to all of you that haven't recieved an update yet, there is an option in settings that will allow you to check for updates. or download anycut and create a shortcut. if you do not know how to follow the instructions in this thread you probably shouldn't have rooted your phone. i have reciueved many PM's about how to do this and as much as i am willing to help you, i expect you to have SOME common sense, if you do not i will not help

sorry man, didn't mean to piss you off, i stated im a newbie, i have the firm belief that nobody learns unless they try it themselves, albeit some help from others never hurts, + the version checker is on rc33, not rc29, hence i cannot take that route, if not i already would have. i guess ill simply continue to wait, phone works fine, just does not load any apps that have to be paid for on marketplace, i work for t-mobile, so im hoping that they may have stopped ota's of rc33 since we are launching 1.5 soon. quick question for those who know, is the build number supposed to be TC4-RC29 115247? this is the one i have. Thanks man!
+ I followed your instructions to a t. and have the classic "rainbow" android boot screen.

What happend to the sticky?? I culd have sworn this was stick yesterday.. PS thanks for this thread as i had to unroot my first g1 now i might have to do my second one .. argg..

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.

Help pleaseee!!!!!

before saying anything i know it should be in Q&A but no one reply me there =[[ and i really need help.
So im trying to root my buddy g1 from scratch, got NBH file and brung the stock 1.6 down to RC29, it went good than i went and download the Root.apk for faster rooting, everything went fine untill i go and upgrade the radio, did the alt L and than atl S and now the damn phone is stuck on G1 bootscreen! So im like alright ill just do a wipe, restatred the phone with the Power+Home wouldnt get into recov menu so i decided to do the RC29 wipe over, i reformat my sd card to FAT32 and than put the Dreaimg.nbh on it and do the Power+Camera but still it just stuck on G1 bootscreen, help?? Please tell me that its not bricked.

THIS IS NOT AN EXCUSE TO BREAK FORUM RULES.
This thread has now been reported, and hopefully, it will be closed before someone goes against their better judgment and helps you.
If you want an answer, have patience and check back in the Q&A. Or, post in the relevant ROM thread. Or, search. Or, don't perform procedures on your buddy's phone if you don't know what you're doing. But DO NOT post in here when you KNOW it's a violation of the rules.

these guys are crawling out all over the place today....feel bad to be a mod today..lol...
you need to slow down friend and reread everything you need to and start from step 1.

If I were a mod, I would've taken the day off. It sounds bricked to me if you can't even get into fastboot. You should've done the one click root.

Ok anyone. Mods are getting really angry with all these post. Ur probaly gonna get banned for posting in this section. Anyway u probaly didn't follow directions. You flashed the spl before u did the radio and got bricked I guess. If u can't get into the bootloader by pressing camera + power or recovery home + power. You are brick. See you in 3 days after ur banned. You should have search first

Ok, I give up --- cant get out of G1 bootie, skateboards & CM/JF recovery -- help

G1 DREAM (really is a dream, right now, a little bad one a little embarrassing)
been 5 mos since I took root via Cyanogenmod's latest G1 stable and last theme was PHRASh Then I thought about checking out
some other themes and clockwork orange caught my eye... Orange is my favorite color, so wehen I saw there was some Orange theme I must've had a dare encounter with myself-- i recall actually installing the Orange theme..... when i asked the phone to flash the theme, it went into permanent G1. Gave it about 12 minutes. Rebooted into recovery (home menu power) and then did what I think got me in deep droid doo doo -- I attempted to restore to my last backup whch was the day before (and ironically the BEST backup i ever made I had it all humming so nice and fast) Guys -- instead of hitting restore to last backup... I actually hit nandroid backup. I know. That was a really bad day and its been a worse 50 hours. I know -- and Ive learned -- OK?
Since that time.... 50ish hours Ive lost track of what Ive done, but its a potpourri
bootloader is dev spl skateboarding, recovery is Cyanogenmod JesusFreke 1.4 recovery.

at first flash of bootloader it says "NO IMAGE FOUND!"
If I press Home when it restarts in perpetual cyclical hell I get into CMJF recovery. I have executed every single option numerous times -- and have not been able to successfully flash anything else -- and now I dont know WHAT to flash. I even tried to go back to root!
If I dont press Home or Camera, I get this....
the awful permanent G1 screen. Forever and ever.
I have Wiped backed up, tried to get update.zip and just about ANYTHING into my sdcard but I dont think they have been successful installations to flash. I am not ADB enabled yet. Surely someone knows what this is all about and I am willing to take a flame for posting in the wrong forum if I can get something out of this, I will pitch in later and help y'all keep these forums in workin' order!
every optioon on the recovery screen which is recovery CM and JF 4.2
When I try to load files according to the instructions in xda and cm i cannot get it in fast enough on the g1 running on the frozen G1 screen because I dont known the time of mount the SDCARD has and when it begins (I know it opens for a while and then closes)
So i got droidexplorer and its almost impossible to get the file in there. I can get it in, and see it, and reboot the phone (and computer)( restore usb connection and I see the update.zip on the sdcard. Then I unmount the phone and reflash and it says something about not being able to find the file.
Whats next? Please dont assume I know what I am doing, I am sure you can tell -- but I am really good at following instructions!

Hello anyone?
I have been up all night trying to fix this phone and i am still not able to do so. I
I cannot get into recovery anymore ------
i am stuck on the hardspl and I have found fastboot again. But I cannot use frastboot if I cannot get any commands into it. Anyone?

ok i get it -
thanks for the help guys! I now have my phone working at a blitzing pace and i am leaving it alone for now. I dare myself to leave it unchanged for a week. Thanks mostly to one of the Dudes on Cyanogenmod.com -- who helped me piece together the missing parts.
Actually -- let me summarize even if only I am reading this
Androids levels of defenses are 1. HardSPL 2. Recovery and 3. normalcy. Lose normalcy (Ok, a beauty of a ROM) you have recovery to get the ROM back -- but the trick is -- can you get the necessary IMG file on your SDcard to update.zip with? Can you figure out ADB and push the update.zip? Can you figure out Fastboot and what it REALLY does and what you can and cannot do with FB? If you can do any of these or FB with ADB, then you have a good chance. Just dont lose the HardSPL. If you give up after frustration and while grinding your teeth waving a white flag, flash the DREAIMG.img file, then you have given up root and FB. But at least you are at RC29, the level where the froot can be found. It is weird hanging out in Android 1.0 lemme tell ya. Feels so 1980'ish with bellbottoms in late decline.
But now its android time at CM with Phrash.
Later
