Cant access bootloader Nexus One! OS boots but crashes.


Guest

Recommended Posts

Heres the deal, and hopefully someone can help me.

I unlocked my bootloader, and rooted my N1, running RFR50.

Then when RFR79 came out, I found a img and updated my phone... then it went wacko. I was getting lots of forced closed apps, "Process system is not responding" and I have no bars of cell service (I have t-mobile), and I have a few moments when the little nexus flare logo comes on, and I guess the desktop restarts. I tried reimaging it to RFR50 again, and it took, but still same errors, graphics look a lil funny/fuzzy, and now when I start the phone with the trackball pushed in, it doesnt go to the bootloader. Now I dont know how to fix it!

PLEASE HELP.

Im somewhat a newbee to the android moding, so Im sorry for the generalizations ;) .

Thanks for any help.

First things first, you need to make your device enter in bootloader.

This is how you can run recovery and fastboot.

So, give it few more tries to get into bootloader

try this:

1. remove battery, put it back in, trackball + power on (fastboot). If this doesnt get you into bootloader, try option 2

2. power on and press volume down (bootloader)

And thats the issue, neither of those work any more... It just shows the picture of the nexus one symbol with a unlocked lock, then it goes to the flying colors of the nexus symbol, and then it boots.

Is there any other way. Also, in the OS, the usb storage option doesnt come up when I plug in a usb to a computer....

Thanks for the suggestion though.

Can you enable USB debugging? If so you can use ADB! Use the command "adb reboot recovery"

Your right, ADB does work while the OS is on

So, I would type adb-mac reboot recovery ____________.img? (with the img file in the same folder on the computer with the adb-mac)

Where do I get a img that has unrooted and fixes my radio back? I have a full membership on modaco.

I think the img I cooked killed it.

Thanks to all!

Well, I think I found another snag, the phone is very unstable, and when I send ./install-superboot-mac.sh to re-root it, to restore backup it responses back with "waiting for device"... and just sits there. Any ideas?

update: fastboot-mac devices comes back without any response

I tried abd-mac reboot recovery

and it reboots the OS, no recovery mode came up.

I can abd-mac shell and it comes back with #

Have you tried holding vol-down, power and trackball while the OS is running then releasing only the power button?

Thanks for the help, but it just rebooted like usual, no bootloader

Don't really know what else to try, except perhaps without your SIM and memory card inserted.

Tried without sim an sd, same thing, it just restarted os, no bootloader

You could this with the AmonRA recovery image file copied to the root of the SD card and type

adb flash_image recovery /sdcard/recovery-RA-nexus-v1.6.2.img

Getting the image on there if you don't have access to an SD card reader might be tricky though, try this

adb push recovery-RA-nexus-v1.6.2.img /sdcard

then

adb shell sync

Good luck

Missed a step or two out, you need to copy the flash_image script across to the phone, full instructions and links are here

Again, thanks for all the help:

I was able to go step by step and got to the last step to type: ./adb-mac shell flash_image recovery /sdcard/recovery.img

but it came back with: error opening /sdcard/recovery.img: No such file or directory

Someone on the internet said to try ./adb-mac shell flash_image recovery /sdcard/recovery.img recovery.img

and that came back with no error, so I guess that took.

But when I restart, nothing changed.

Found more wierd tings going on, I can join wifi, and go to webpages, but the market freezes and when the phone crashes with the X graphics, it closes the market again. Cant download anything. Then, I found that when looking at the space of the sd, it says: total space unavailable, available space, unavailable.

Im about done trying to find a answer, and I think my phone is bricked. Can I send it to HTC and pay to have it restored? Is there any "well established" folks on this site that are up to the challenge of fixing it for a fee??

Can you not do;

adb reboot bootloader

to get into Fastboot and then use fastboot to reinstate the recovery & boot images?

It might be an idea to flash an older radio onto it as well as a known good 2.1 image.

ADB should be available from mid-way during the boot process once the underlying OS has initialised.

Thanks for your response but adb reboot bootloader just has the phone reboot directly to the OS.... It wont boot to the bootloader.

So you've managed to fry at least part of the bootloader.

The string you used above;

./adb-mac shell flash_image recovery /sdcard/recovery.img recovery.img

Might not work - the 2nd "recovery.img" is unnecessary. You should've got a couple of lines of text afterwards saying that it was doing something. On a mac you WILL need the ./ in front of the command unless the adb-mac binary is in a searchable path (which it won't be). You will probably need;

sudo ./adb-mac flash recovery /sdcard/recovery.img

which should do the job. The fact that the phone won't boot into the bootloader is not encouraging though. If you can get the recovery image to work and restore a nandroid backup of a working image AND flash a known good radio image then it MIGHT get it going again, but I wouldn't be on it.

the "shell flash_image" you were told to use relies on an app in Cyanogenmod which may, or may not be on your phone. I think it's pretty standard in most images(?) now so it should be ok. The string above should work though.

Assuming the "adb shell flash_image" works, and you have a nandroid backup, then you can flash MOST of the partitions with that command, more info here:

http://forum.xda-developers.com/showthread.php?t=532113

if it doesn't work, then you can download and install the tool from this page;

http://wiki.cyanogenmod.com/index.php/RE-recovery-img

Includes instructions on how to get it onto the phone.

Gotta say that I don't fancy your chances though...

Thanks for your response and help on this. Yes, I was just leaving ./ out of the post, but I was using it. When typing the command:

sudo ./adb-mac flash recovery /sdcard/recovery.img I get a response of Android Debug Bridge version 1.0.25

-d - directs command to the only connected USB device

and so on (all the switches and uses of adb-mac)

So thats not working still. People say there is plenty posts about sending the phones to HTC for repair, but I havent found one yet on how/where/how much $ etc. Any ideas?

as for the instructions on http://wiki.cyanogenmod.com/index.php/RE-recovery-img

I am fine until the last directions: adb shell flash_image recovery /sdcard/recovery.img

Yes, Im sure recovery.img is on my sd card too!

I get the error back:

error opening /sdcard/recovery.img: No such file or directory

Does:

adb shell

get you to a $ shell prompt? If so you could try running "flash_image recovery /sdcard/recovery.img" directly from there.

You may need to use;

adb remount

first, but not generally needed for sdcard access. From the shell you could try;

cd /sdcard

ls

and see if you get a directory listing and make sure the recovery.img file is showing up. It's case sensitive too, so "Recovery.img" is not the same as "recovery.img".

yes ./adb-mac shell gives me a # but no $

I used ./adb remount (remount succeeded)

so I tried ./adb-mac shell

#cd /sdcard

#ls

(it didnt give any responses, no listing of files)

Like I said in a earlier post, the phone gui says that the sd card size is unavailable and the sd available space is unavailable. Do you think thats stopping me from accessing the sd-card?

People who had sent their "usbbricked" Desires were being quoted around $150-180. It's just a matter of calling HTC's repair department.

If you can sift through the output of

adb shell cat /proc/kmsg

you may be able to spot errors (and post some relevant chunks) Once you can get a file onto the sd card you should be able to repair yourself.

$ adb shell

# mount|grep sdcard

/dev/block/vold/179:1 on /mnt/sdcard type vfat (rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702

allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro)

tmpfs on /mnt/sdcard/.android_secure type tmpfs (ro,relatime,size=0k,mode=000)

Do you get an output similar to that? If not your sdcard is not mounted, and you need to look through logfiles to find the error, or wait for someone more experienced to show up and help you with the mounting.

Did you try sending fastboot commands before trying to reboot to fastboot? That may actually work even if it does not show you the fastboot prompt.

Something like fastboot boot recovery.img to get into recovery.

Since you obviously cant seem to get flashing a working recovery to proceed.

Have you tried just booting a recovery image, not flashing it ?

fastboot boot recovery.img (or whaterverthenameofrecovery.img)

This should boot the device with the specific recovery (AmonRA i suggest) and then you could from there perhaps restore a working nandroid backup, or flash a complete image from an update.zip file.

This is all of course assuming that you can figure out why you cant list / access the sdcard.

Did you try

adb push recovery.img /sdcard/

adb sync

adb sync is to ensure that the file is written in complete to sdcard.

Does the adb push command spit out errors ?
