[Q] Nexus One Boot loop - Nexus One Q&A, Help & Troubleshooting

Hi Everyone,
This is my first time attempting to root my nexus one.
I used the One-click root application posted on these forums and the ROM manager to try and install Cyanogen 6.0RC2. Now my phone boots into the loading screen with the particles flying together to form an x, followed by the same animation in blue instead of the android colors, with a skateboarding android icon in the center. About 10 seconds later, it seems to fail and go back to the multi-colored animation. This loop continues forever until I yank the battery.
How do I get back to a working environment?

Did you install the froyo baseband?
Did you have 2.2 on before you installed CM6?
Did you wipe as is recommended by Cyanogen?
Try installing CM6 again THE PROPER WAY... read their post on the forums and then report.

I already had Froyo on here. How do I bust out of this boot cycle to try again?

pull and reinstall battery and boot to recovery

a boot loop is normally caused by an incorrect flash, either by the recovery just being weird or the phone not correctly wiping prior to flashing. Did you make backup before you flashed?
If so here is what you do.
Boot into recovery
go to wipe
wipe "data"
wipe "cache"
and wipe "dalvik-cahe" (so long as you only select these three your sd card will remain untouched)
(if you want to resstore back to stock)
go to restore/backup
hit restore nandroid
select the restore point
(if you want to continue to install CM6)
go to "install zip from sd car"
select the zip
once done install the gapps zip (if you donwloaded it)
reboot
Done

How do I get it to boot into recovery?
When I remove the battery, and then power it on, it goes right back into the boot loop.

Nevermind. It's working now. I think I forgot to wipe first.
Thanks so much for your help, everyone!

Error wiping and stuck with flashing ROM

So I decided to root my phone, following everything here (I am completely noob at this):
http://forum.xda-developers.com/showthread.php?t=694572
I did screw up on step 10 where instead of doing a "Flash zip from sdcard" I did a reboot and it booted into the original system. So I went through the process again from step one and did everything right this time.
I don't know if that broke the root or not, but I cannot flash anything on the phone, mainly new ROM.
When I try to wipe it will give me this error:
"error wipe dalvik via adb"
"error wipe ext via adb"
If I go and flash the ROM anyway, it will get stuck at the splash screen forever...
Fresh Rom 2.3.3 will give me the endless droid dance
Cyanogenmod 6.0.0 Test 4 For Hero CDMA will be stuck at the "X" animation
I can pull out the battery stuff and it still doesn't work. I am able to just restore my nandroid backup and the phone will work then.
Does anyone knows what did wrong? Or how I can get this to work?
PS: I have the "Superuser Permission" ninja is my apptray so I assume I rooted it correctly...
Make sure your battery its charged when flashing. Re-download whatever files you want to flash, sometimes they get corrupted during download. Which recovery are you using?

also if when your in the recovery image for the first time or you have been in there for awhile i get those errors but usually a shut down and the boot back into recovery works for me
I managed to get this working with Rom Manager after restoring the nandroid to the Sprint ROM. Running on Fresh 2.3.3 now, thanks for the reply!

[Q] Stuck in CWM recovery after Doc ROM install, help?

First of all I hope this is in the right place: I did do a search but still couldn't find any help.
Here's my problem:
After getting a (delicious) taste for customisation after rooting and lagfixing, I decided to give custom ROMs a go. Hours of indecision passed and ultimately I settled on Doc and Stefunel's magical ROM. Due to currently being on 2.1, I chose to follow the set of instructions provided on the page for doing so.
All was well up until the very final step. When rebooting the phone through ClockworkMod Recovery, instead passing the Samsung boot screen into the Android system, the phone boots into CWM recovery. I've tried doing another factory reset, and reinstalling the ROM to no avail. I've also tried mounting "/mnt/sdcard" in order to place another ROM to flash from, but I keep getting a message telling me to insert a disk (what happens when you don't mount).
That's pretty much all there is to it. I'd be massively grateful for any help!

If you have made a backup of your apps then flash the JPY with Odin and then make factory reset in recovery mode. Then root with CF Root 1.3 (Or something like that) and flash CWM Recovery. That's what I would do.

from the recovery menu try wipe cache and dalvik, and reboot

problem with custom roms (boot logo loop after goes sleep)

Hi, problem starts when ROM is on the phone, everything works good, but when display dims, after few minutes phone goes into boot logo loop (no restarts no nothing, just goes into boot logo loop) and only way is to hold down power button to restart phone.
This happens to me with CM7, MIUI, ICS ports. I will try to describe how I do flashing.
1 -> Samsung Galaxy S with stock rom (xxjvt)
2 -> flashed CF-Root xx_jvt kernel (through odin) to root SGS
3 -> booted into recovery, wipe all four available things (cache, factory reset, dalvik, battery stats)
4 -> flashed CM7 (once)
5 -> flashed ICS (onecosmic's port) (once)
6 -> rebooted phone, everything works perfectly, but I can't let go phone into sleep mode.
I was asking for help before, and I got told to try to flash stock again, and then CM7 (because with CM7 happens the same for me)
So I went back to stock, but didn't flashed any custom rom because I was waiting for RC/Final versions of ICS port.
So does anyone have any clue how to fix this, or tell me the "Right or Best" way to flash custom roms.
Thank you.
The way I flash is:-
Backup all apps using titanium backup, then copy the titanium backup folder from the internal sd card to the external sd card.
Remove BOTH the simcard and the external sdcard, boot to recovery goto mounts/storage and format sdcard. (that wipes the internal card and removes all crap)
remove battery and replace, boot to DOWNLOAD then using ODIN flash the pit file (512), repartion, flash the stock rom (PHONE,MODEM and CSC files)
Phone will then boot to stock
Replace the sim and external sd.
Boot to DOWNLOAD again and flash your kernel, I use semaphore found no issues at all with it. Reboot phone.
Reboot into recovery, do your 4 wipes then
Flash your cm7 or custom rom you are wanting to use through cwm.
Flash any desired theme.
If the phone goes into any boot loop then I just flash VOODOO kernel via ODIN and then disable all the lags in cwm.
This usally lets me flash what ever I want..and I have flashed my phone too many times now
Hope this helps you matey
Thanks, I also got PM from lgsshedden with other possible way to solve this.
fallowed your guide now, everything went OK so far, will post back in few hours if my issue is solved, thanks.

cm7 to cm9 problem

followed the instructions to update from cm7 to the cm9
- Upgrading from CM7?
Do a Nandroid Backup!
WIPE (wipe data/factory reset + wipe cache partition)
Install the ROM from internal sdcard using ClockworkMod Recovery
Optionally install the Google Addon
Click to expand...
Click to collapse
after the cwm flash phone reboots and shows the following:
1) AT&T white screen (from what i've read thats the pbl)
2) quick flash black screen
3) AT&T white screen again
4) a very quick list of text from what looks like cwm but too fast to read
5) repeats
Any ideas what went wrong?
I do have my phone back up and running but on Gingerbread via One Click K12 with Boogs kernel now. Had to use my home made jig to get into download mode...
Boot into recovery and flash the Glitch V14 Kernel first then CM9. It should fix that problem.

thanks for the reply, i'll give that a try once i get back to cm7
No, you just need to flash the ROM twice as the first flash sets the new partition layout and boot.img(kernel for MTD ROMs). Wipe EVERYTHING but SD card and boot.img in mounts and storage. Then flash again and flash GAPPS without rebooting!
hmmmmmmm, my memory is for crap, but as i recall once the rom flashed the first time the phone tried to reboot and went into what i would think would be called a boot loop. i wasn't able to boot into recovery to flash the 2nd time even if i knew to do that...
as i said though, i may be wrong.
To get out of the bootloop I usually do a battery pull and then do the 3 button combo to get to recovery and flash the second time
ok, i'm up and running although i thought at first something had screwed up again. Since i was coming from stock/rooted gb i used these instructions this time:
- First time flashing ICS to your Captivate (or coming from another ROM)?
Root your device and install ClockworkMod Recovery.
Reboot into Recovery using 3-button-combo
Do a Nandroid backup!
WIPE (wipe data/factory reset + wipe cache partition)
Install the ROM from internal sdcard using ClockworkMod Recovery
Optionally install the Google Addon
Click to expand...
Click to collapse
after first install i went right into the bootloop i described in my first post except this time it was the cm screen twice instead of the at&t. I used the 3 button hold to see if it would go into recovery, and it did
On b-eock's suggestion i then flashed the rom again...this time i got to the screen with all the tiles rotating across the screen, but after a few min i got an "encription" error and message that the process was intrupted and i had to do a factory reset... i click "ok" to see what happened and on the next boot i was up and running
Thank you gentlemen for the assistance

LG optimus 2x bootloop after failed cyanogen mod

Hello!
Today, i decided to install cyanogemmod on my 2x. So i downloaded ROM manager and downloaded cyanogenmod. everything went fine until i was going to boot for the first time. I got into a bootloop. so i tried taking out the battery and all that stuff but it still would't work. So i tried to recover the phone. I recovered it to a month old backup (I could not find the one i made in ROM manager before i installed cyanogenmod) The recovery went fine. But, when i rebooted it got into a loop on the lg logo! (the one without the loading bar) it would just load the lg logo, be there for like 10sec, then it would do the same. I tried recovering one more time, but it didn't work. The same thing happend. What should i do? :S Should i wipe data/factory reset?
EDIT: My phone was on android 2.3.4 before i download cyanogenmod.
BTW before i installed cyanogenmod, i forgot to clear cache and data. I was in a hurry so i did't notice the screen popping up, I automatically pressed "ok" without selecting anything.
Thanks for the help

Different partitions... Look for something called backtoext3 in the dev section (or somewhere else) The problem is that when you flash a custom rom like CM you convert your filesystem to EXT4, while stock is EXT3.
So basically what you have to do is:
1) Reboot into recovery
2) Wipe everything
3) Flash Backtoext3 zip
4) Restore Nandroid.
This should work. this will take you back to stock.
So i have to restart the phone, Choose wipe data/factory reset, then flash backtoext3 (how do i do it? lol) then restore nandroid (the backup i just tried to restore twice?)

Yes
Flashing backtoext3 is just flashing the zip file you put on the sd card. (and then install zip from SD ) an then restore your nandroid stock backup and you're back on stock.
But you said you wanted to try CM right? In that case, wipe everything (factory reset/data + cache + dalvik) and then flash the CM7 rom and you have CM! Don't worry about backtoext3, your partitions are already on EXT4, because of your prior CM flash.
Ohh! Thanks Can you send the files for cm (2.3.4)? I've found some, but im not sure if my phone is compitable with them :S im really afraid to mess something up again
My. Signature. (CM7 temasek's KANG = the best CM7 at the moment )
I did everything and i got into a bootloop at the skating andriod screen again
OK, restored my phone back... Now it wont connect to the network and the battery has a question mark inside it. It also says the battery level is 999% heelp
Nvm, got my phone back to normal still dont understand why cm wont work...
You need cwm5 to flash cm.
I have a G2x, which is basically the same phone. But anyway, I would recommend nvflashing CWM and not getting it from ROM Manager.
CWM 5.0.2.0 will do just fine, but it is indeed old...
Anyway, are you sure you waited long enough on the CM boot screen? The first boot might take a couple of minutes. (4 or 5)
