[G1 Android Development] uva463:
Anyone? I really do not want to brick my phone. While connected to my PC, the command prompt pops up for a second then closes automatically. I obviously did something wrong as Im not able to get into recovery.

Thanks again
[G1 Android Development] ThR1LL:
Do you have adb fully setup?
[G1 Android Development] uva463:
:o

Wrong USB drivers

g1 unroot

after i unroot it take 3 day to update back to version 1.5 .what do i do when i get the update do i turn the phone off do i press alt l alt s .please help thak for the help
[G1 Android Development] swivel:
I'm following all of the steps in the OP, but I'm having a bit of trouble. After applying the original SPL (renamed to update.zip and flashed in recovery), it says "reboot to complete update." So I reboot, and the screen flashes a couple of times and then the phone reboots back into recovery (1.4). At the bottom of the recovery screen it says "Formatting CACHE:..." but just hangs here for what seems like eternity. I can still choose to select any of the recovery menu options at this point, which leads me to believe (perhaps erroneously) that the phone has completed all operations. My only real option at this point is to reboot the phone. When I do that, it just hangs forever at the first T-Mobile G1 splash screen. What am I doing wrong? I'd really appreciate speedy assistance because I have to get this phone back to T-Mobile ASAP and I'm heading out of town in a few days. Thanks in advance.
[G1 Android Development] Misiek_ud:
I have the same opinion that original SPL isn't necessary before DREAIMG.nbh. In DRE is included spl, radio, system, splashes, recovery, etc. so everything should pass OK like themadbogart said. I have reach polish RC5 (I guess), but I'm afraid to return on it. I'dont know is there OTA?
[G1 Android Development] swivel:
Please respond. Don't want to start a new thread.
[G1 Android Development] ThR1LL:
I currently have Haykuro's SPL installed. Is it possible to Unroot my phone or will attempting brick my phone? If I can would I flash the original SPL then DREAIMG.nbh?
[G1 Android Development] supraman_tt:
I used the guide located at here to gain root on my G1. As I am in the UK I used the RC7 image. Now that I am selling the phone, I want to put it back to the way it was. But when using the files from here, it says that "Not Allowed" when I turn the phone on pressing the camera key and power button. Can anyone tell me where I can find the correct DREAIMG.nbh file for the UK.

My SD Card is formatted as a single FAT32 partition.

Thanks
[G1 Android Development] swivel:
Good lord, someone please answer our questions already. This issue is time-critical, at least in my case. If nobody answers, what choice do we have other than to create new threads?
[G1 Android Development] s15274n:
Not sure how you guys are having trouble with the partitions... surely you did not partition the stock SD card that is a 1 GB Class 2. TO that, surely you are not sending T-Mo an upgraded SD card.

What issues are you guys telling T-Mo to get a new phone? My G1 is a champ and I can't imagine what could be better... what is wrong with yours that you have to return it? Obviously they work okay if you are rooting/flashing roms/themes.

Sorry... just don't get it.
[G1 Android Development] swivel:
This post is worthless and does nothing to help. Please don't post if you can't offer assistance. Try thinking before you post. To answer your thoughtless question: my G1's "K" key on the physical keyboard has stopped responding. It's a hardware issue.

Now do you get it?
[G1 Android Development] s15274n:
I wanted information, I asked a question... it is not worthless to me.

You have asked a question and are still waiting on an answer. Be nice and perhaps you will get it.
[G1 Android Development] tubaking182:
if you already flashed the SPL to your phone then you need to flash the DREAIMG.nbh go to the bootloader and do that, after that the phone is stock and there is nothing more that you need to do.

on a side note please do not be rude to our members, some people have lives and are not just on here to solve your problems, this thread was made so that there would be fewer threads asking how to do this and people could just read through this thread and try a few things for themselves before asking.
[G1 Android Development] swivel:
I'm sorry, but if you really read his post, you'd see that it's pretty much off topic and served only to clutter this thread, not add to it or help. Thanks for your attempt to help.
[G1 Android Development] tubaking182:
i answered your question and you did not post whether or not you tried it and you are being very rude so you get to wait until someone else wants to try and help you. please be kind
[G1 Android Development] Monban:
If you follow this directions exactly, isn't there a chance you could brick your phone on step 6? If you're on SPL 1.33.2005 (aka Haykuro Danger, or Haykuro Special) I'm pretty sure the phone will insta-brick as soon as you flash a radio other than 2.22.19.26I.

UPDATE: Wait no, I see you reflash the SPL first, nevermind, that's what I get for not paying attention.
[G1 Android Development] supraman_tt:
I googled it and found the dreaimg.nbh for the uk from here

used the spl from page one and followed the steps from here and i have unrooted mine now. thanks for the guide, but no so much for the help.
[G1 Android Development] recasper:
Greetings. I am in the process of recovering the phone back to its original state. I have successfully recovered back to scratch using this guide. But in trying to bring it manually to date with RC29 for auto updates, I have ran into an issue. (reason for manually upping it: It hasn't updated to the new firmware and 1.0 doesn't have a "check for updates option).

Anyway when I put the RC29 (update.zip) on my card and attempt to gain Recovery Mode (Home+End) it gives me an error icon directly after the G1 Opening screen. Triangle with an exclamation point above the a phone graphic. And I have to pull the battery to reboot.

Does anyone have any ideas as to what I am running into? Or a possible remedy?

Could be the file I got it may be bad, but I tracked down what seems to be a valid file through the boards. Seems, just about every link to download the "signed-kila-ota-115247-prereq.TC4-RC19+RC28.zip" (update.zip) file is broken and I had a heck of a time finding it. Just hoping its not the file. Or rather that it is, and someone has an idea where a good file download link is located.

Thank you in advanced.

By the way, I couldn't find anything by searching. Case in point why I went ahead and asked. My sincere apologies if I called off my search to early and this has already been addressed.
[G1 Android Development] DirectMatrix:
If you are running into the traditional triangle and exclamation point after hitting home and end, then that is the default recovery image that maybe your not used to seeing after using JF and Cyanogen's image for so long. Once in that screen you can just hit Alt+L to give you a list of your options such as Alt+S Alt+W etc etc. I suppose I could be misunderstanding you, but this seems to be where your at....
[G1 Android Development] recasper:
Direct Matrix, thank you so much. Good call on noting the JF info in my sig.

That worked like a charm. I have had this image on my phone for far to long and completely forgot about this aspect of the recovery.

Thank you so much again for the heads up.
[G1 Android Development] DirectMatrix:
No problem recasper, that's what we're here for. Glad it worked out.
[G1 Android Development] recasper:
That's the truth, this board exceeds expectations when it comes to assistance with the Android system.

In lieu of the help, I thought it appropriate to give back in return. It may not be a big hand but every little bit helps. I realized many of the links posted to download RC30 and RC33 have become broken and I had trouble tracking down links that worked. For anyone out there looking for them. Here they are below.

The following are the links I used to find each of the files

RC30: http://www.zshare.net/download/51047970e7581999/

RC33: http://www.kyubinc.org/files/signed-PLAT-RC33-from-RC30.f06aa9b3.zip
[G1 Android Development] Legion09:
hello, I've done a hell of a lot of searching, including google....and I cannot find a download for the official t-mobile us cupcake build. I just wanted to go back to stock, but the phone updater says I am up to date while stuck on rc33.

The one link I did find is broken. Wondering if anyone had it mirrored somewhere...thank you in advance...
[G1 Android Development] tubaking182:
Hate to be "that guy" but look up one post, he seems to have linked them otherwise send me a PM and I'll see if I can track it down and email the file, I think I have it on one of my computers(just not sure which one or where)
[G1 Android Development] Legion09:
nah, he linked the rc30 and rc33....lookin for the official cupcake...I may have found it in my downloads, gonna try and flash it and see what happens...but may just be one of the multitudes of roms I have dl'd from here...:P
[G1 Android Development] tubaking182:
My bad, I was thinking RC33 was 1.5 I forgot about 1.1, but I found 1.5 on my sdcard so if you wanna send me a PM with your email I'll send it your way unless you already have it, I need to update my first post and include the t-mo US update so people can go to RC29 and then recovery to flash the t-mo update. Let me know
[G1 Android Development] Legion09:
Found it! have attached it to this post, it's the original 1.5 OTA cupcake release, pre-patch....

nvm, too big to attach....
[G1 Android Development] ThR1LL:
Does that anycut update trick still work when trying to go from RC29 to CRC1?
[G1 Android Development] beyondspexj:
hello, i know this maybe a silly mistake i made somewhere but hear goes:

when trying to flash the origional SPL back onto my phone i am getting and error. what the screen says:

installing from sdcard...

finding update package...

opening update package...

E: Cant open /sdcard/update.zip

(no such file or directory)

Installation aborted.

now i did download the SPL from the link in the origional post and renamed it "update.zip", copied both files to my sdcard via card reader and reinserted the sdcard into my phone. what am i doing wrong? i currently have the RC29 (or so it says) installed. thank you all for any help! running off 2 hours of sleep isnt helping me at all and hopefully i just made a silly error somewhere!
[G1 Android Development] gospeed.racer:
try to rename it as just "update" and see if it asks about changing the extension. if it does not, then you simply had your file extensions hidden, making your renaming look like "update.zip.zip". This is pretty common, the next most common is not formatting the card properly.
[G1 Android Development] beyondspexj:
thank you gospeed. i will give this a try when i get off of work ( since i left my usb cable and card reader @ home! ). I never thought about just renaming it "update" instead of "update.zip"

the way ive been reformating the card is going to "my computer" then right clicking on the card on the F: directory and selecting "format". is there another/better way to get it done? thanks again for the help!!
[G1 Android Development] orimps2:
Is this the same coming from a HERO rom?
[G1 Android Development] menzo44:
Just a quick question.. I know you must erase splash 2 image before unrooting, but if I only changed splash 1 do I need to change that first also?

edit. Just thought I would let everyone know.. you dont have to it changes it in the process on page 1, thanks!

[howto] unroot

so here is the CRB43 OTA if anyone needs it .. this is not the latest CRC1 but should get you a lot closer .. and you do NOT need to wipe the phone to unroot .. you can unroot and maintain eveything on the phone .. simply flash the original recovery.img and then flash the OTA to the phone .. all apps stay and nothing happens besides loosing root

[G1 Android Development] Lowlypeon:
All right folks, I botched a flash, and the phone now hangs on the logo. When I try to restore it using this method, I get the errors "No signature (5 files)" and "Verification failed."

Also, loading into the bootloader doesn't do anything but give me some sort of colour test. The only two files on this SD card are the update.zip, and DREAIMG.nbh.

Am I boned? And if so, can I use my backup on a new phone to get my info back? I did a few searches and didn't see a solution, so I apologize if this has been answered somewhere. Just link me, if so.
[G1 Android Development] Afirejar:
If the phone is in a position to give feedback like "Verification failed", I assume you can get into recovery. The "colour test" you describe sounds like the stock SPL. If you can get into either of those, you're not bricked.

Flashing an official rom from recovery, like the one linked a few posts back (if you're in the US), or applying DREAIMG.nbh from SPL (see instructions in a rooting how to if needed) should set you back on track.
[G1 Android Development] Lowlypeon:
I'm using the files from OP when I get this error. And when I'm in the SPL, I can't get anything to happen. Supposedly pressing power is suppost to begin the process, but it does nothing.

rc29 to OTA

Thanks for the info found on the thread unrooted yesterday at 3pm to rc29 and my phone collected OTA update at 3am. Granted I kinda miss my Macdroid theme. lol
[G1 Android Development] jwongso:
I am considering Unroot to resolve GMAIL and Contact issue (in chinese) on the T-mobile G1 phone owned by a friend. All other programs on the phone are English. On startup, the phone display "G1 T-mobile" then "Android www.hiAPK.com".

Reading this thread, I assume the "www.h1AFK.com" is splash2 screen. As the SPL is "Original G1", I need to replace it with "Engineering" SPL before I can run "fastboot" to remove the splash2.

Is there an easier way to fix the GMAIL and CONTACT without going thru UNROOT? I am downloading Android SDK 1.5 (183MB) now jus to get the dll file needed for FASTBOOT to work..

Thanks.

Phone won't boot or install update

My phone was crashing and wouldn't boot up fully so I decided to unroot it. I believe I succeeded because my recovery system looks like when my phone was stock and unrooted - blue text with only options to reboot, apply update, and wipe data. However, my phone won't start up fully and my splash image is still a custom one. After the G1 logo and the custom splash, my phone stays on blank screen.

I tried reinstalling updates via recovery utility but no matter whether I try rooting again with cyanogen update or with R29 update, it always says:

E: no signature (x files)

E: Verification failed

Installation aborted.

Is my phone rooted or unrooted and how can I fix this problem? I would prefer to have my phone rooted again but I have no idea what to do.

BTW I also tried fastboot but when running Dreaimg it flashes green text that disappears too quickly to read.

Any help is appreciated.
[G1 Android Development] crawldit:
The Micro SD slot on my G1 has stopped working so I am trying to unroot and get back to stock using ADB on my Macbook. I have downloaded the files from the original post but get errors when trying to flash them.

I know I'm setup correctly because I can do "./fastboot-mac devices" and it lists my phone. I am only running into problems with the 'update.zip' and 'DREAIMG.nbh' files.

I am using "./fastboot-mac flash update update.zip". It sends to the phone just fine but when it goes to write I get "FAILED (remote: partition does not exist!)"

I get the same error with the DREAIMG.nbh file as well.

Any ideas?
[G1 Android Development] mrHiggins:
help!

long story short my phone started rebooting randomly... not the normal boot loop, it would get fully booted to my home screen, be fine for a few seconds, reboot, then turn off after a few seconds of the g1 logo. i repartitioned/formatted my sd card (back at 100% fat 32, no more ext) then applied the instructions/files included in the OP. everything was going great but then for the past half an hour my phone has been stuck at the radio_v2 portion of the dreaimg.dbh update for about an hour.

so yeah, i haven't touched it sense that update started and i don't know what i should do from here...
[G1 Android Development] abirkc1:
I can't flash the original SPL to my phone. It says verification failed. No signature.

How do I fix this. I'm not sure if my phone is still rooted because the recovery screen is the factory one with blue text. When it was rooted, it showed different options and I was easily able to flash.
[G1 Android Development] mrHiggins:
crisis adverted

i'm all fixed. i thought i plugged my phone up but as it turns out it wasn't plugged into the wall so my phone sat at the radio_v2 stage til it died, then i just plugged it up, rebooted and tried again and it worked.

when reading the instructions and it says 'do not interrupt' in all caps with multiple exclamation points, that gives me the impression that detail is dire thus my mini-freak out in my previous post.
[G1 Android Development] DMaverick50:
I know it says in the op to use the nbh but if its a tutorial then in imo it should really mention the step that must be taken whereby you must unzip the dreamig.zip and pull out the dreamig.nbh from there

still the simplest unroot tutorial i could find, thank you

although i never figured out what the op meant in step 7 'gettig'
[G1 Android Development] maybeoneday:
I think the op was thinking if your smart enough to root your phone then your smart enough to know to unzip. Maybe I'm wrong just an assumption.:rolleyes:
[G1 Android Development] DMaverick50:
thats logical

sure makes me feel like a dolt though :rolleyes:

[howto] unroot

you shouldn't need the nbh file at all to unroot .. i did an unroot process without wiping the phone at all .. flash the original recovery.img to the phone and boot into recovery (HOME+POWER) and then flash any OTA update.zip that is NOT one of the partial updates (ie. patching files) .. i did this method and it worked great .. so you can root, unroot, root, unroot your phone as much as you would like and never wipe or lose files
