[Q] Nexus One stuck on reboot screen

[seb0]

My Nexus One is stuck on boot screen and keeps recycling/vibrating. To condense information, here are bullet points of the situation:

-Nexus One 2.3.6 with unlocked bootloader
- PASSIMG.IMG is wrong or missing in HBOOT
-Can't access the sd root because I lost my sd adapter
-I've tried to fastboot recovery-RA-v2.2.1.img and Clockorange but I think that because I don't have the SU files in a folder titled SU on my sd, it doesn't go into the recovery menu
-When I cmd fastboot devices the serial comes up, but when I cmd adb devices, nothing comes up
-Can't access sd storage to move the SU folder via cmd


I've been working on this the past two days and searching and trying anything and everything. And nothing has worked. Any help would be great.

You don't need anything on your sdcard (or your sdcard itself for that matter) to put a custom recovery on your phone. Try this after putting your phone into fastboot mode and getting your cmd prompt up on the computer:

fastboot flash recovery "c:\location\to\recovery.img"
fastboot boot recovery "c:\location\to\recovery.img"

From here, try a factory reset.

And adb won't be able to see your phone until you are either in recovery or fully booted up in Android (only with USB Debugging enabled).

When I do "fastboot boot recovery recovery-RA-v2.2.1.img" it comes up cannot load recovery.

Any ideas?

And once that goes through, do I boot through recovery on the phone or through command prompt?

Thank you for the reply.

 

[bassmadrigal]

Is the recovery in the folder where you are typing the command? And have you verified that the md5 sum of the recovery is correct?

And, I always just change the command from flash to boot to boot into the recovery the first time. Otherwise, if you are running a stock Android version, your recovery might get restored back to the stock recovery (Android has checks in place for that).

Nevermind, I did get it to go through, but then my N1 reboots on its own and is still stuck at the bootscreen

 

[bassmadrigal]

Ok, do you want to continue running stock, or would you like to try a custom ROM? Because, it sounds like you will need to reload your ROM (assuming the Factory Reset/Data Wipe didn't work). They have a couple of rooted extremely close to stock versions on here, or you might want to give CM7 or MIUI a shot. I would also go and get temasek's system-only format since Amon_RA doesn't give you the option to format your /system partition. You can find the file in his mediafire folder http://mediafire.com/temasek

My original intentions were to put CM7 on my phone because Gingerbread began to crash a lot. So in that case, how am I supposed to install the CM7 ROM onto my phone if I can't get past the bootscreen?

 

[bassmadrigal]

So, the fastboot boot command doesn't work?

 

[seb0]

fastboot does work, adb doesn't

 

[bassmadrigal]

No, does the

fastboot boot recovery "c:\location\to\recovery.img"

get you into recovery? Or does it still freeze on the X screen (when you say bootscreen, I assume you mean the X)?

 

[danger-rat]

Sounds like the recovery isn't installing with fastboot? Do you get any error messages?

 

[seb0]

It will still freeze at the X and never boots into recovery.

It will still freeze at the X and never boots into recovery.

I got exactly the same problem as you. Didn't you see my post?

Btw, the fastboot boot recovery "c:\location\to\recovery.img" command doesn't work, whoever gave that tips.

I got an idea, but not sure about it:

Get someone who has a working Nexus One to make an nandroid backup, and send the boot.img and system.img and fastboot it into our devices?

What do you mean it doesn't work? I know it works because I've used it many times. Does it give an error? Are you actually changing the c:\location\to\recovery.img to the proper location and name of the recovery file?

Yes ofc i got the path right. It gives this error:
"cannot load 'recovery'"

 

[bassmadrigal]

Yes ofc i got the path right. It gives this error:
"cannot load 'recovery'"

That typically means that it can't find the file (which seems like it is looking for just recovery, not recovery.img or whatever the name is). Have you tried using tab completion to make sure it is the right filename?

If i write wrong filename it gives me another error. Yes the filename and path is 100% accurate.

I'm trying to fastboot flash system system.img to then fastboot boot boot.img to my N1 but everytime I flash the system.img it gets stuck a 1/4 of the way.

So basically, can someone please tell me how to get my N1 to stock so I can start from scratch with the CM7 flash?

Here is my system info:

-Nexus One (Unlocked) - T-Mobile service provider
-Android Version- 2.3.6
-Baseband Version- 32.41.00.32U_5.08.00.04
-Kernel Version- 2.6.35.7-59465-g42bad32 [email protected] #1
-Build Number- GRK39F

I have fastboot access but no adb access.

If you can provide the necessary files needed for this I would greatly appreciate it.

Have you tried any additional recoveries? It has been awhile since I used that command, but I know it has worked in the past.

You won't have adb access unless you are in recovery or booted into Android with USB Debugging enabled.

Where did you get the system.img and boot.img files from?

This was the only system.img and boot.img file I could find.
