[Q] Help|Endless loop and system failure - Nexus One Q&A, Help & Troubleshooting

The Story:
I bought a new Nexus one.
Got the OTA updates and updated the phone (first 2.1 then 2.2 and 2.2.1)
Since then the phone is not rebooting properly. usוally it just reboot and reboot and reboot.
After I formated the SD card the phone booted succeussfully but crashed again after a minute back to the endless loops.
can someone please help?
I tried to unlock the bootloader, root the device and flash Amon's recovery but although the cmd windows said that it ewent alright besides of the open lock sign nothing seems to change.
Please Please Please Help, It's a brand new phone...
p.s.
if there is any way to just erase everything (already tried earse cache and userdata from the recovery...) and get a "new" phone - please tell me how.
I know how to use adb/fastboot, I'm not a noob...
Thanks a lot!!!

Where is my question...?
I can't find it...

It's right here.
Anyway, I suspect your problem after flashing recovery is you're rebooting, and the OS is reverting to stock. Go straight into it first, take a backup and wipe it.
Failing that you'll need to grab FRG83 image from http://developer.HTC.com and use fastboot to flash over system.img and boot.img

You'll be able to format every partition on your Nexus One by using Clockwork Recovery.
By Amon's recovery you can do similar thing but it doesn't offer ability to format System partition (it's not quite useful to format System partition anyway..)
You mentioned that your phone could boot successfully with a formatted SD card and then ran into problem, my guess is that your SD card has bad block(s), please verify this by take your SD card out and use your phone for few hours, is there any stability issue?

so... an update:
I downloaded the original files and flashed them all in fastboot (recovery.img, userdata, boot and system).
The phone is on the "nexus-one sign" screen for over then half an hour now and nothing seem to change.
a. Is there somthing else that I should do? how long it should take...?
b. what are the odds that it's a hardware problem...?
c. could it be a problem related to incompatible radio?
Thanks...

and other update...
even after reflashing the original files I can't enter recovery (original) so I guess the problem lies within it.
with this information and the other messages - does anyone has an idea...? please...?

did you try another SD card?
try this and let me know if it works
kuldrivedotcom/host/n1/Back2Stock.zip

Thank you, but the problem solved.
It was a big HARDWARE problem.
HTC knew right away what the problem is.
Sent the phone to HTC, got it back in 3 days, everything work just fine since.
Thanks anyway...

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.

Help with root, cant get into recovery image!

okay I followed regs guide and when I reached the part to where I have to run the command to flash the custom recovery image
regaw says it may take many seconds for it to complete
when I do it it takes less than 1 second and when I run the final command to reboot the phone into the recovery menu it simply boots up normal
I have tried booting while holding the home button and still a no go
I think the recovery image isnt flashing into my phone for some reason...
but cmd says it was successful , any help apreciated
can anyone help?
please, I've followed everything as it should be.
I've tried 3 computers(2 running XP , 1 running windows 7)
I've Hard reset the phone everytime I have tried to perform the root
Everytime I flash the recovery img it says its successful but when I place the comand to reboot into recovery my phone freezes and I have to do a battery pull.
I don't get what I'm doing wrong
I have all the files in the correct directory
I have usb debug on
I have set the phone to charge only
I have htc sync installed
any help apreciated :/
just mount your sdcard copy the recovery to it again then try to flash it once more. it could have corrupted the image on the first copy. if that doesnt work. try to download the 1.6.2. recovery image and flash that.

can you point me to where I can find that download?
Thanks I will try to mount the card now
No luck putting the files directly into the card ; ;
what else should I try?
I'm having the same issues. I'm running a brand new hero not even activated yet that has 1.5 (sprint send me new one bc couldnt revert.. didnt know root was coming) ANYWAY I need help.
I have root and I've copied damage controls zip to my sd card. I tried rebooting into recovery mode and i get an error picture so I had to reboot.
this is frustrating.. can someone give me step by step including commands that I should type? I can load the sprint 2.1 and unlock (have old version) but right now im as frustrated as all the other noob's.
it sounds so easy but im clearly doing something wrong..

Error Rooting CDMA Hero 2.1

I am very new to this - my first time rooting a phone. I followed the guide and everything seemed to work perfectly until I got to the step to make a Nandroid backup. I get an error: "Error : Run nandroid-mobile.sh via adb!"
I then tried re-booting without making a backup but my phone just hangs at the white HTC screen. I tried cleaning off my 2GB sd card via USB-MS toggle and deleted everything except for the files put there at the beginning of the process. But had the same error when I attempted a Nandriod backup.
Next, I tried running the backup via adb but got an error that the Device or Resource is Busy.
I really need a working phone fairly quickly and am ok without having an original backup if that is what I have to do.
Could someone please give me a hand?

1.81 GB currently. I have even tried flashing a couple of ROMS but when they finish, I choose Reboot and it still sits on the White and Green HTC screen.
Have I bricked it?

Highly doubtful.
1. Reflash your recovery image
Code:
flash_image recovery /sdcard/recoveryfilename.img
2. Try a Nandroid (if it fails oh well, too late now)
3. Wipe everything under the Wipe menu when you get into it.
4. Reflash your rom
5. Reboot - It really could take up to 20 minutes some times.
if it still wont reboot:
6. Power off
7. Take the SD card out.
8. Reboot.
If it still doesn't boot post back.

-Ok, tried reflashing recovery but it said header is same, not flashing recovery.
-is the rom I need to reflash the boot-patched.zip file?
Thanks for all of your help. I don't know what happened on this one but it got hosed somewhere in the process!
Hoping I can get it running again soon as it is my only phone and I have 2 kids at home.
UPDATE
Ok-
Loaded the 1.6.2 Recovery. It allowed me to run a NAND Backup.
However, after loading the ROM I still end up locked on the White background with the Green HTC letters on it?
Any other ideas? I have not seen anything like this googling and reading forums.
Try taking the battery out for a minute. I would just reroot from scratch and follow the directions step by step.

How would I reroot from scratch? I can only get into recovery mode. Is there a way to do it that way?
Try this thread.
http://forum.xda-developers.com/showthread.php?t=657086
Me personally, I would unroot, then root all over again.

This phone had 2.1. That is a guide for older versions. Plus, I can't get into the OS to make the changes to debugging and such. I only have access to Android System Recovery.
I should also mention that the command adb devices returns a
000000000000 Recovery
Is this normal? It is in recovery mode so, I am not sure.
I am starting to think it is a brick.

[recovery/device/sd error?] Nexus One not flashing

Hey guys i don't know if anyone of you had the same issue but any info/help could be helpful.
I used to flash my N1 A LOT! but today i have this strange issue. I wiped and flashed rodriguezstyle again for a clean start, but i only got the colorful X with the unlocked symbol at the bottom and then just a black screen. i thought I've done something wrong and flashed again, but with the same results.
i changed my sd and downloaded again the rom but still no luck, did a nandroid restore and the phone was working properly. then i got a bit frustrated. downloaded 2-3 more roms but the result was the same.
i read somewhere that flashing with battery <50% may cause some errors so left the phone off to fully charge and tried again... no luck
then i remembered i upgraded the radio and i downgraded it to the old one, but still the same results and nandroid doesn't work... jeeeesh... back to the new radio and to my nandroid, but its no fun owning a smart-phone if you cannot flash it.
anyone with the same issue or any helpful tips/instructions?
Try this:
When the phone hangs at boot, reboot to recovery, wipe cache and dalvik-cache and reboot from recovery. Does that work?
If not, you'll need to logcat the boot process and post the log somewhere for us to have a look at.
So, assuming adb is working on your computer, plug in via usb, use adb logcat > output.log and reboot the phone. Continue logging for about 60 seconds after the phone stops.
Post the log to www.pastebin.com and then link back here.
hmmmm ok i will post results in abt an hour. thanx!
hmmmm i think i sorted it out... reflashed recovery. propably i messed smthing in there! thanx for your effort!
Hello everyone!
Weird problem here, too.
I was backing up my SD card in view of a format/cleanup....and when I went to boot into recovery, my N1 was stuck on the black screen with the white letters at the bottom "Build : RA-nexus-v1.7.0.1"... The phone actually boots great, it is just not loading the recovery image. Is it possible that part of the flash got corrupted? If so, I'm pretty much done flashing my N1, right???
I'll post a log asap (if it could help any)...
Oh and btw i tried to re-flash Amon-RA's recovery twice already...Superboot said it was successful....but I doubt it...
Well try flashing stock rom! I flashed it through fastboot step by step and it worked. Also check if the rom you try to flash needs ext partition or if apps2sd is enabled

[FIXED]System Partiton Inaccessible (Worser than you think)

So i was running BCM ICS and came across a Sense ROM, so i changed the partiton scheme on blackrose to 250/10/176 without any problems, when i went into recovery i encountered the usual message that occurs in 4EXT Recovery when you change HBOOT Partiton, something like "ATTN: 4EXT HAS BOOTED INTO SAFE MODE BECAUSE THE FOLLOWING PARTITON IS INACCESSIBLE 'system' IF YOU HAVE CHANGED HBOOT PLEASE WIPE ALL PARTITONS (EXCEPT SD-CARD)" Now this happens to me all the time so i went into the wipe menu and started to do that, half an hour later i noticed that it was still stuck on "Formatting system" and boot was wiped so the phone will now boot straight into the bootloader. This is my main phone that i use to answer important phone calls with so i really need the magic of you guys to help me in this situation.
Thankyou.
I also forgot to mention that flashing a rom wont help as the recovery will go onto the progress screen but will freeze after that
I figured out that i had to use fastboot erase system. It works now.

FYI: If you solved the problem yourself, then please edit your original title with the word "Solved" so we know you don't need any further help.
Thanks, but this new layout needs getting used to, I don't suppose you know where to change it?
