phone reboots to bootloader image with 3 skateboards

i have a class 6 adata 8gb 2gb ext4 64mb swap rest fat32
im running cyanogen 4.0.2 or 4.0.4 whichever one i load up from sd at the time, but both are stable. i have newest radio and spl also. the issue is simple. i can get into recovery mode and bootloader menu. everytime i reboot it goes to bootloader menu(3 skateboards). camera button is not held down either or stuck. the only way to get past this screen is to evertime i reboot to factory wipe and install new rom which is a pain. i was wondering if by having the original image DREAIMG file in a folder on my sd is whats causing this. but now that i cant get past this screen i cant remove it from sd. i also already tried mounting sd to comp from console using: "ums_enable" it does nothing(tried it on 3 computers). im tired of reseting and reflashing. pls some assistance.

Have you tried to reflash the SPL? You could just redo the entire root process and replace everything.

New Isuue, Same Problem
Sorry it took so long to get back here. No I haven't tried that. How could it be the SPL? Im asking it in a meaningful way, like why and/or how could it be?
I will reflash the SPL tonight and edit post if it works.
I also erased my sd card and re partioned in in "parted" it booted fine. The battery died today and i rebooted it and BAM! bootloader screen again. So i factory reset and flashed a new ROM image. then it worked fine. now only problem is the private apps i have installed wont work and they get stuck on uninstalling....Whats the fix for that?
Thanks XDA!!

You need to start over and replace everything. It sounds like you have multiple problems. Use THIS guide starting with the downgrade bacause it will reflash EVERYTHING on your phone. If the problem persist then it's hardware issues. Redownload everything, don't use anything you already downloaded because these files might be bad too.

Trying to Root

I have followed the steps in the guide and I have searched but have not found the same issue. On the first step where I flash RC29 it goes through and says that it completes successfully but then when it reboots it sits on the G1 screen. I let it sit like that all night and still will not start up. I have tried reflashing RC29 and different downloads of RC29 but still can not get it to load.

Reload the dream file and start from scratch. Check the forum for the unrooting thread if you don't know where to get it or how to flash it.
This also assumes you can get to a recovery screen........

Unfortunately, I have tried that and I have tried several different dream files. Every time it says that the flashing was successful. It just wont reboot.

Can you list the exact steps you took?

What region is your phone from? RC29 is US, RC7 is UK.
Hah, 1024 posts! *nerd-gasm* Continue...

I formatted the class 6 4gb sd card to fat 32, copied on RC29 image.
I turned off the phone. Holding in on the camera button hit power the rainbow screen came up it then flashed, it came back and said successful. I hit the action button, it started to reboot and just stayed on the G1 Screen.
It is a US phone. I tried doing the European build but it said it was not a match and would not flash.
It is the PVT board as well.

Stuck on bootloader screen.

So I had root access. (i.e. when I first booted my G1 up it said something about a developer phone) and I tried flashing the dreaimg.nbh file to go back down to RC29. It fails every time won't let me do anything else. It just stays srtuck on the bootloader screen when I try to reboot. I've tried about everything I could think of and I'm at wits end. I really hope this problem can be fixed. Does anyone have any suggestions or know what went wrong? Thanks.

Re-download dreaimg.nbh file again. The one you're using may be corrupted.
Why do you want to go RC29 if you have root access? You should be able to flash anything on your phone as is, RC29 is only needed to gain the root.

It won't let me do anything. I'm unable to do anything to the SD card. Although, while typing this I just thought of something. If I got a card reader I could erase the file from my card since I can't do anything to the phone. Maybe that would work. But who knows because I've tried removing the card and booting up and it remains stuck on the bootloader screen. I literally can not do anything else, it's just permanently stuck like that. So I can't mess with anything. And the reason I was trying to downgrade is because I was trying to start all over again but I think I might have ended up screwing myself instead...

I am may be wrong, and please forgive me if I am, but from your post count I am getting the picture that you're pretty new to this.
Tell me if what you did is any different from these steps
You booted phone into h-boot mode holding power and camera buttons
Your phone found dreaimg.nbh and ran it on it's own.
You restarted the phone and got stuck in the boot loop.
Confirm that this is what happened

No, your assumption is not wrong at all. I am pretty new to this.
Yes, I did reboot my phone while holding down the camera button.
It found dreaimg.nbh and ran it but it failed so now I'm stuck in the boot loop with it constantly trying, and failing, to load dreaimg.
Thanks so much for your quick responses.

When it says "failed to load dreaimg.nbh" it means that it does not see it. I have a feeling that a file that you had was zipped.
Let's do this
Boot into recovery by holding power and home buttons
select wipe/factory reset or something along those lines and try booting up a your phone again. I'll be lurking around so just post what you find.
Take a note of which recovery you're running while you're at it too.

No, the file I had was not zipped I don't think cause it sees it and tries to update. It says update in progress then I get the progress bar but when it's finished it tells me: Update Terminate. Update Fail. Then it just goes back to the multi-colored bootloader screen and won't shut off. I can reset it by pressing call+menu+end but then it just starts all over again. So, I can't boot into recovery mode. Matter of fact, the only way to turn the phone off is to remove the battery. Otherwise, it just starts in bootloader mode and continues this viscous cycle.
At this point I don't even care about installing a ROM or anything, I just want a working phone.

I see. Yep.. you're S.O.L.
Just to make sure... when your phone is off and you hold power and home buttons it just goes to h-boot screen, right if so then unfortunately there's only one thing to do: get a card reader, re-download .nbh file and start over. At this point you have no working recovery or rom on your phone. Once you get that going you should be on your way to secure a root and flash whatever rom you need to.

Is it even fat32?

Damn. That's what I thought. I should have just left well enough alone until I did more research and knew exactly what I was doing but I get ADD when I'm hungover. Oh well. Thanks for your help.

This will happen from time to time.. it's always desirable to have a card reader handy. Also.. since you have nothing to loose, this would be a great time to re-format and re-partition your sdcard so you can start squiky clean.
Good luck.... let us know when this is worked out by adding [SOLVED] to the title of this thread.

[solved]bootloader won't let me update

So usually I've read this is a matter of the wrong spl, or unsigned files, or other things that don't seem to be my problem. I've searched for days now and would LOVE some help.
I'm downgrading for a warranty return because my touchscreen doesn't work. I try to follow the directions found in several threads but I get hung up at the same spot.
When flashing the dreaimg.nbh file in the stock bootloader, bootloader starts, checks, then I get to the screen that asks you to press power to flash, or action to cancel. No buttons on this screen do anything. Not the "3 finger solute" to reboot, not power, not action, nothing. Just no response. And yes, I waited, and waited.
I think I've tried about every combination of everything I can think of, but please, your suggestions mean a lot to me.
The only thing I can think of, is that maybe the updated radio isn't compatible with RC29, and the phone knows this somehow and won't let me flash RC29 with my current radio? Does that make any sense? Do I need to flash an old radio, then the dreaimg.nbh?
Thanks!
(anybody wanna tell me how to get a screenshot from the bootloader and I'd be glad to show it, but it's just the standard screen)

I say try! ahaha
Same thing happened to me with the touchscreen lol.
I just flashed the old image didn't even bother to update or anything and just sent it in.
And I didn't get charged for voiding the warranty.

And no the new radio is compatible with RC29 I've used my friends phone when we were rooting it and he had the new radio.

Thanks for that, if I can't figure it out, I guess I'll try the warranty. I'm still going to work on it though, I can't imagine that someone hasn't had an unresponsive bootloader before though, and know how to fix it.
I've always done things the retard way, but I've spent the last week learning ALOT. I've got adb and fastboot setup, is there a way to flash the nbh file via fastboot or adb, bypassing the bootloader?
And FYI for others, with the nonworking touchscreen you can't "press the droid" after a factory reset. SDK, and androidscreencast fixed that, you can see your screen on your computer and use your mouse to click!
http://code.google.com/p/androidscreencast/
I also just got droid explorer, which lets you do lots of things with a GUI, including invoke androidscreencast, man that would've been easier a week ago! At least now I am able to use the phone as I had to disable the wipe unlock, and touch the droid to recover from a wipe!
I imagine this would be perfect for people with broken screens as well!

the .NBH includes EVERYTHING but an SPL... it rewrites Radio, splash1 system and usrdata...... if you cant press the action button, first try re-flashing the SPL, then try cleaning out your trackball
the action button is the trackball BTW...

Thanks for those tips. But I've done that and it still doesn't work. Even tried downloading the spl from a variety of sources, and doing a checksum to make sure it's not corrupted. And the trackball works in every other application. Basically, the stock bootloader just won't respond to any command (action to cancel, power to update, 3 buttons to reboot, nothing). It DOES recognize the .nbh, which is a step further than most bootloader fail threads I see.
Is it possible to flash an nbh file using fastboot or adb? I've figured out how to do update.zips this way, but not .nbh. I'd still have a custom bootloader, but everything else would be stock.
Thanks again everyone!

So if anybody can help, maybe this bit is useful too, I get no response from the hard spl either. Example, it is my understanding that the standard hard spl screen (with no .nbh file on card it dislplays phone radio info at top, serial0/10, 3 android skaters at bottom) that screen I should be able to press call+power+menu to reboot, right? I get nothing, and thought I should. This spl won't flash the nbh either, I guess because it won't register the "press power to contine".
1. Any ideas? My keys work when in standard usage and in recovery, why won't they work in any of the spls?
2. still wondering if/how I can fastboot the dreaimg.nbh file?

Make it unbootable (don't brick it - just wipe your current ROM and recovery partition) and restore to stock G1 SPL and if they say anything about "It won't boot" blame it on shipping.
Have you tried updating with a engineering SPL? I don't know if that would have any difference. Also, is your sdcard still partitioned? I think it has to be all fat32 or a goldcard (no idea where a goldcard actually come in on G1).

Brilliant! I bet it is the partitioning! I now remember that I thought about that for a minute, but tried other things. I'll try a fresh, all fat32 partitioning and give that a shot. Otherwise, good call on just deleting the partitions.
(actually excited to have something hopeful to try for a change!)

Solved!
Cheers to you R3s!
If anybody else finds themselves with an unresponsive bootloader, make sure your sdcard is not partitioned.
For the step by step folks who may be wanted to return a G1 to stock, in my case for a warranty return because the touchscreen doesn't work:
put the stock 1 G card in a card reader, popped it in the usb drive of a winxp system, my computer, right click on drive, format (not quick) fat32.
copied over stock spl renamed as update.zip
copied over DREAIMG.nbh
unmount sd card
pop into g1
home+power to get into recovery
apply update.zip
reboot
wipe
reboot + hold camera button
power button to apply
wait, this time I got the status bar immediately
action button to restart when prompted
reboots to spl
3 finger salute to reboot (call+end+menu)
BAM, back to the android to press the button to start
(and fully stuck there now since I don't have a touchscreen, my daughter called me crazy for being so happy, she asked if I fixed it and I said no I broke it!)
So there ya go, anybody else has this problem, reformatting the sdcard isn't enough, you have to remove the partitions.

Root Loop?

Hi all,
I downloaded the modaco update-nexusone-FRF50-signed.zip, and flashed my stock 2.1 (out of the box) nexus one rom, it worked well for about 9 hours, i plugged it into my car charger and when i took it off, it froze, and the touch screen disabled. Now im trying to reflash the rom and keep getting stuck at E: Can't mount /dev/block/mmcblk0p1, then E: Can't mount SD card
Any ideas on how i can get this working again?
Thanks

reinsert your sdcard, I have issues where the sdcard doesn't sit properly. This is assuming your using a2sd

i have a few times, same thing keeps happening, is there anything else I can try before I chalk it up to hardware malfunction and send it in to get a new one.... i reaallly dont want to do that
im also tried different sd card, and none of them have worked.

Well..... I wouldn't consider it to be a hardware malfunction yet.
1. Have you tried a non-apps2sd rom, like Stock Froyo
2. Have you tried completely reformatting your SD card on your desktop, while using a MicroSD to SD to USB converter or something of that sort. You'll need to delete all the partitions as you won't be able to see the EXT partiton in explorer, use disk manager
3. Have you tried using a different SD card?
4. Maybe you should completely wipe all the device in fastboot, maybe something is screwy, maybe even reinstall your recovery image
Try these things, then come back with results. We can diagnose issues after some of these troubleshooting techniques

i haven't tried formatting the card, but i have tried other cards with the update.zip flash, do you have a link to the stock froyo file
i think the problem is that the one i downloaded wasnt legit, and i have wiped the device in fastboot, the problem is that something is wrong with the touch screen, when it relaods from rebooting, it will get to the touch the android welcome screen and wont register any touch screen input, only volume up/down, trackball, and power button

okay, i tried formatting the sd card, and putting the update.zip file on it, and the same error occurred, when i tried to flash in recovery mode.

any update on what i can do to fix this?

Flash the original recovery image. You can find it http://forum.xda-developers.com/showthread.php?t=614057
You would do this through fastboot. Its easy, try that out

how do you do it through fastboot, i've only flashed through recovery

Put the img file on your sdcard, boot into fastboot, it should automatically check for the image and you should get a prompt asking for you to continue installing the image

no luck, it doesnt search for the image. When i enter fastboot, it just shows four options: bootloader, reboot, reboot bootloader, and power down

Then I would say something is faulting with your SD Card or your SDcard slot. I would try and take a very small ammount of rubbing alcohol and a q-tip to the contacts of your SD card, but there is no way to get into the slot without damaging it. If you have to do a warranty replacement just state that yes your device is bootloader unlocked but you're a developer and it is necessary to unlock in order to better serve the android platform
