[Q] Nexus One Recovery then clear dalvik cache - Nexus One Q&A, Help & Troubleshooting

I am new to these boot menu.
I was told, clearing Dalvik cache may help clearing up some of the unused cache so I wanted to give it a try.
I was then told the procedure is like this:
1. turn off the phone
2. press vol down and press power once to get into the menu
3. choose recovery using vol down key and press power to choose it
But when I did all these steps, it goes to the N1 boot logo and then a screen with a "!" and an android and stopped. Is this normal?
I was told it is supposed to give me a menu to choose choose "wipe cache partition" then i can reboot your phone again (even though it may be a bit slower).
Anyone nice enough to give me a walkthrough?
Many thanks.

Once you see that ! With triangle around it hold power and hit volume up and it should take You to recovery

CWM 3.0.1.0 Lockup

Wiped Dalvic using CWM to prepare to restore an older kernel. Now frozen on screen with Reboot Recovery as top choice. No buttons do anything. How do I unbrick?
I have had the same thing happen a lot with 3.0.1.0. Just hold down the power button until it shuts off, and the turn it on like normal.
Not sure what is going on with wiping cache and causing this, but I hope a fix comes out soon.
Trist
I run into this problem every single time when doing any kind of CWM work. As posted above, just hold down power button, and if you need back in CWM just hold down the power button and the N button for 5 seconds after the reading screen.
Worked! Thank you!
I found a way to keep it from locking up when wiping dalvik.
Go into wipe dalvik as normal but don't press yes.
Back out of the menu (power button) I then wiped battery stats (I don't know if this step is required) .
Then wipe dalvik like normal and it won't lock up.
If this works for others please post it in the dev forum (not enough posts yet) .

Just tested it again, no need to wipe battery stats.

So just hit "Wipe Dalvik Cache," hit the power button to back out of the menu, hit "Wipe Dalvik Cache" again, and then hit "Yes"?

Installed CM7 with Gapps for 6.1....HELP!!!

I initially intalled CM7 after cleaning cache and Dalvik and backing up my current ROM using Clockwork. it went good unitil after booting I accidentally installed Gapps from 6.1
Now it boots and loops from the blue CM7 screen to the green andriod asking ' Touch to Start '
I dont know how to get out of this loop or to go bak to recovery manual mode. Please Help. Any chance we can fix this
Thanks
Pull your battery to get out of the bootloop. Then press and hold home while pressing the power button. That should take you to your recovery, where you can wipe and reinstall CM7.

EDIT: I am late to the party, nvm.
I did what you said. When i press power and home button the only menu option i get is 'Clear Storage' to which i pressed yes and 'Menu reset' which i pressed yes. it reboots and back to the loop. Back to loading CM7 and 'touch to begin'
The party is still on. As said installed CM7 with Gapps for CM6 accidentally and now stuck in endless bootloop. Trying to fix it. First suggestion hasnt worked so far
OK so you don't have a recovery (I'm guessing you tried to use rom manager = bad idea). Do you have ADB?
I think I do but have never used it ir dont know how
Is there any hope of recovering the phone or is it just better to get a replacement from Sprint

You need to pull the battery, press volume down + end button (at same time) in order to get to the bootloader. You should then see the skateboarding androids. Press the home button to get into recovery and wipe/format boot, system, data, cache (just to be sure) and then reflash and flash the right gapps.

I doubt sprint would even look at it, let alone fix it or replace it, once they see that you rooted.
Also, I've flashed older gapps with cm7 and didn't get loops. My guess? You forgot to data wipe before installing cm7.

Thank you so much. That finally got me into reboot. Now waiting for reboot with fingers crossed Thank you
Well something went wrong and for all you guys out there with Sprint. They did replace my phone. All i had to do was call and tell them that I was at their Service center to fix the phone and those guys couldnt fix it and it is stuck on the boot screen. But i think i will manage to salvage this before my replacement arrives
Lessons Learned
So the big lesson here is when you need to get into recovery press the volume down and the home button simultaneously and your home free. Thanks to all who helped
Update - Issue Solved
So i did mange to get into recovery and wipe everything off and reinstall cm7 again. Now i hope to flash the right gapps and ill be in gingerbread heaven

If you have a sprint hero, that is actually not correct.
hold home and press power = recovery
hold vol down and press power = bootloader
I don't know what's up with your phone, and I'm glad you fixed it, but if I were you I would reflash a good recovery image just to be safe. Also, make sure when you're getting ROMs you get them from a thread in hero cdma and use the gapps also linked in the OP of that same thread (don't use rom manager IMO). Always flash from recovery and follow the correct steps, that way you should not run into "issues" again. Also, my best encouragement for you, is to search and read. Happy flashing
If you have big fingers, pressing the power button can sometimes press the search button or back button, often causing you to boot into bootloader instead of recover.

Yeah, I have to use my thumbnail which will eventually chip off the paint or whatever it is on the button.
Ha. I actually place the phone on a flat surface a press the buttons.

Hold down the HOME button and then hold the POWER/END CALL button til the phone screen comes on and that should boot you right into recovery if you're having problems with the volume down method

[Q] Does anyone know the key combination of entering recovery mode?

Does anyone know the key combination of entering recovery mode?
Okay ours is a bit weird. With phone off hold power and volume down. When lg logo appears release power and press again. It'll bring up confirmation dialog on a factory reset. Ignore that and hit yes both times. It'll bring up a screen saying authorizing factory reset and then after a moment will boot into your custom recovery. Enjoy

[Q] Flashed Root IMG Unable to Wipe Cache

Hello all,
I used Mofo to flash Computerfreek274's image 1.5.3a. His thread states that the cache needs to be wiped after flashing. While still in fastboot mode, and after flashing the image, I used the volume keys to select Recovery. Hit the power button and then I have an image of an android that fell over and a red exclamation over it. No text on screen. If I use the volume keys, nothing happens. If I hit the power button the phone turns off.
What step did I miss in the instructions? Or what is the correct procedure to wipe the cache?
Thank you,

You have to hold vol up for a couple seconds and then hit power at the same time. Then release and you will see the menu.

Thank you! I have it wiping now. Initially, from a powered off phone, I tried your steps, but that just booted the phone. For other newbies, here is a more detailed process.
WIth the phone powered off, hold Vol-Down, then press the Power button (while still holding Vol-Down). Release both buttons. Fastboot mode starts. Use vol (arrow) keys to select Recovery mode, then pressed power button. Motorola logo appears, and then the android with the red exclamation mark. No text on screen. Hold down Vol-Up for a few seconds, then press power (while still holding Vol-Up).
Now there is text on screen. Use vol keys for arrow button and highlight "wipe cache partition." Use power button to select this option.
Screen changes to Android standing up with a blue bar at the bottom of the screen.
Now wait. Other threads have stated the wipe may take 30 minutes to complete. Phone should power off once wipe is complete.
Thank you,

Just an update, my wipe completed. It did not take very long. The phone restarted on its own and came right up. Everything working at this point.

Locked Phone

My daughters Motorola X 2nd Gen (XT1095) seems to be locked. When you touch the screen all that shows is the time and a padlock. If you try and slide the padlock up, down or to the left or right the date shows at the top and the battery shows but it will not proceed.
Can anyone tell me what may be happening and how to fix it?
Thanks
I would first hold down the power until it turns off. It sounds like a restart is in order

Restarted it several times, results are the same, still locked.
Sorry to hear that. I didn't see it in your post so I started with square one troubleshooting.
How about rebooting to recovery and trying to wipe the cache?

Sorry, should have said that. How do I boot into recovery and wipe cache?
Thanks
1. Power off the phone
2. Hold volume down and press the power button
3. Press volume down until you get to the word recovery then press volume up
4. When the little android is laying down, press the power button and tap volume up.
5. Use volume down to get to wipe cache partition and press power

That just means the bootloader is locked. It has nothing to do with the problem you're having. Try a factory reset if wiping caches didn't work.

Get the phone to the bootloader. Open a cmd on your computer and type MFASTBOOT ERASE USERDATA. that'll factory reset it for you.
