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

build numberer kila-user 1.0 tc4-rc30 116143 ota-rel-keys,release-keys

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....

recovering from a brick..

I'm not sure how it happened, but i bricked her. It should be easy to recover hopefully right, because i have JF 1.3 rc30, and the engineering bootloader, anybody that can tell me what to do now?

DREAIMG.NBH would be the fastest way for me to answer this question.

i did the same thing!
well what i ended up doing was downloading the rc29 image (dreamimg.nbh) and putting it on my sd card then putting the sd card in my phone and then hold the camera button and power on! it wipes everything and you have to re update to jf modded rc 30 but its the quickest way for me! and like 20 mins later im back where i was....

thanks guys.

You have also fastboot flashed your system.img, userdata.img and your boot.img from a nandroid backup.

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

possible brikc plz help

ok so i had jf 1,4 with radio rc33 and i tried to put a theme on it and when i rebooted all i am getting is a tmobile g1 start up screen i was trying to put buuf theme on rc33..plz help asap..

you mean you dont have a card reader? you have to find a way to put the file in the card to re-flash it, or just do a wipe ALT+W and press home+back to reboot, that way you are bypassing the theme, do not install the theme again unless you have the LITE version

just did wipe and still not booting past tmo g1 screen...and no i dont have a card reader...and trust me i wont be putting any more themes on with out reading more in depth

sorry to tell you but you gonna have to get a card reader or another phone to load the jfv1.42_RC33 or RC30 (or wherever file you had before) and re-flash it
EDIT: wait a min... do you have ADP ?

You can either use flashboot (any image will do really) or try to find the culprit with adp (if you can get in).

ok yea whats flashboot and what do u mean by find the culprit with adp and if u can get in...not following u
only thing im able to do as of right now is get to jfs bootscreen(is thats what its called)

OMG! Buuf not even support ADP how did you load it with out reading before?

IDK...guess im not the brightest crayon in the box...i actually clicked the wrong dl on media share ment to dl rusty metal..or something along them lines and assumed buuf would work...am i screwed?

ok u ned zum flashbut imgs try http://andblogs.net/images/snapshots/ kk? then u ned 2 flesh it uzing dis mithod http://forum.xda-developers.com/showthread.php?t=462512 omg XD XD dunt wory dat itz cupcake ur just truing to gt access 4 now
*sigh*

not your not, there is a way to fix it, but I cant help you on that, perhaps somebody else

ok but i cant mount my sd doom how will i put anytihng??

as I said, you are going to need a card reader or another phone where you can load the file

so as long as i can get a card reader and re dump jf 1.46 on it illbe fine?? and just re do the firm ware..i just lost all my contacts apps ring tones and such right?? im ok with loseing that crap as long as i can get my baby (g1) back up and running...

yeah, you'll be ok by doing that,

ok well thank you for helping as much as u did...even thou im still fraking out not gonna lie. but thanks. and mods please keep this thread up for the next few days as i should correct this problem today hopefully. but incase i need to consult the g1 jedi masters i already have an open thread to do so ...and again thanks guys...ill be sure to stop assumeing and make sure i read b4 i dl but in my defense dl was described to work with jf 1.46 rc33(didnt have lite listed)

1.42.
(was annoying me)

Fastboot Help (Rid me of my headach)

Ok, lets start from the beginning. I have a gt that had non-rooted rc33, i downgraded to rc29, rooted it, upgraded to rc30, and now to jf's rc33 1.41, obviously still rooted. Once I got to rc33 1.41 i finished re-installing all the programs i had lost along the way (going to rc29). Then I changed my boot images (splash1 and 2) using fastboot. Everything was fine untill i went to change my boot images again and powered on using camera+power and the grey screen pops up first since i left it on my sd card (dont remember what the grey screen is i just remember not to interupt it but im sure if youve rooted youll remember what im talking about), well instead of clicking the trackball i accidently hit the power button, wiping my phone once again. I went back to rc29 and rooted it (wasnt sure if i had to so i just did it (i had the time)) then back to the rc33 1.41 by jf. got all my programs back the way it was before. i noticed when it booted into rc29 the first time and everytime after that my splash1 screen was back to stock but my splash2 screen was the one i had put there. so i powered off after i got all my programs installed and went to change my first splash screen, and now once i exit out of the grey screen (yeah i know, still on the sd card) it goes to the RGB screen (the normal screen), not the skateboarding androids, and definately not fast boot.
My question: Without going back through the ENTIRE process all over again, how do i get my fastboot back? I may of missed it on the forums, but I promise, it wasnt for a lack of searching, LOTS of searching (and not just this forum). Plenty of forums tell me how to use fastboot, just now what to do to get it back...
Thanks in advance for your help..
(oh and if it makes a difference I recently installed a theme more details can be provided if needed)

Since i take it that you are already rooted.. then i think it should be easy.. just download the bootloader devs edition again and place it in your sd card and then go safety mode and update it again.. but i think the reason why its going to the gray screen when you press camera + power is becuase you may still have the dreaimg.nbh file in there.. i would delete that first.. then put the modified bootloader and then update it and see if that works... Those are my thoughts hope it help.. good luck

yes i know that its the dreaimg.nbh i just forgot what the name was, and yes i should definately delete it since its what got me in this situation to begin with lol
now i found the bootloader i need (i got bored and decided to root my girlfriends g1 while waiting for an answer and found out that i forgot to use the bootloader like i had before) and have it on the sdcard, named as update.zip, waiting to be installed, but before i do it, am i going to lose all of my programs again? i have 127 programs, many of them (like locale and such have settings edited) that i do not feel is worth having to go through a 3rd time
so not my only question is, when i hit alt+s am i going to wipe my phone again?
Oh and thank you for such a quick responce n8izzle, and another thing, why safemode?

No it won't wipe your programs if u install the boot loader. And by safe mode he meant recovery mode (i am sure). If u want to be on the safe side go to recovery mode first and then do a NAND backup by pressing Alt+B which will back up all your partitions if something should go wrong again. Then update bootloader.
So Alt+B first then Alt+S and then u should have fastboot again and also backup images of ur phone on ur SD card

hey sorry had to restart my computer i just got ubuntu .. but yea thats what i mean not safe mode but the other lol... but hope that you got it working if not you can pm me and i will walk you through it...

Yeah I didn't put 2 and 2 together than bootloaders wher part of the rc updates lol, it makes perfect sense to me now, how's ubuntu?
Oh and can anyone elaborate on exactly what's backed up with the backup tool in the recovery menu and how to restore it
(New to linux incase anyone was wondering, I've always wanted to get into it but every class I've taken for my certs for web development has been for windows os, so hang in there I'm a quick learner lol)

ubuntu is pretty cool i like it.. im not too familiar with it but i initially got it so i can partition my sd card... so i'm learning on this as well... if you are talking about backing up your phone with nandroid it works great... you can view the directions and all below... if you want i can help you step by step if you run into problems.. just pm me if you do...
