please help me un-brick my phone

ekh... bought a nexus one off craigslist. it was already rooted. i used it for a day and then decided i didnt want to keep it, so i decided to do a hard reset. it's now stuck on the screen with the four different colors (nexus symbol) and the unlocked lock on the bottom. i've done the clear storage by holding the volume down (or trackball) and pressing power. i've tried to go through all those settings and cleared everything, but it still wont load..
any ideas? do i need to re-flash the original rom? can i flash a rom if it doesnt boot up? please help, as this is my first android phone and i've had it all of 24 hrs.. thanks
omar

Omar,
Please read the second sticky post in the forum "[ROM] Original Shipping - Tutorial" This has all the files and will tell you the steps to return your phone to the original shipping rom.
You can skip to step 5 once you download the necessary files. To get into fastboot mode on the phone do the following:
1. Power off the phone
2. Hold down the volume down key and press the power button (continuing to hold the volume down key)
3. Release both and it should boot into a white screen with the top, highlighted, option being fastboot
4. Press the power button to enter into fastboot mode. The screen should say fastboot-usb in red
Once you see fastboot usb you can begin to erase and flash the roms per the instructions.
FYI: The fact that your phone is booting to the four colored X logo means that your phone is not bricked. It is simply in some sort of boot loop. A bricked phone will show nothing on the screen and will not connect to the computer in any way shape or form.

if anyone can help me via AIM i would really appreciate it. i think i'm just about there, just need a little more info

i'm trying to figure out this fastboot thing.. i got the USB thing to work, so now my computer detects the phone. i downloaded fastboot but it keeps giving me some error message that it cant find some file... any ideas from there? thanks
omar

ok.. found and downloaded the sdk, and now when i open fastboot, it just closes right away.. wtf am i doing wrong?

You are running fastboot from a command prompt right?
To open a command prompt type "cmd" into run.

Posting a thread in the right forum might get you some help. =]

Hope you have a custom recovery (most likely). Hold volume down and push the power button. Then on the white screen, press volume down once and select Recovery by pressing Power. Hopefully, you'll have Amon Ra's recovery. If so, then you will be sent into this recovery screen where you can turn on USB mode which will allow you to connect to your computer so you can download a ROM onto your SD Card. Do that.
Then you disconnect...wipe everything under the 'Wipe' settings...then Flash the new ROM. You should be good to go from there!

The first time I flashed an ICS ROM on my D4 it bootlooped as well. I had to wipe data and cache and then it booted right up.

Yes I know I gotta wipe both cache and data and I done it twice, but still nothing show up.....it is just the blank black screen, no any animation at all...

I'm freaking out because mine is stuck on the black screen too... I was trying to flash the XML file for Fastboot. and it just went blank (blackscreen) can someone please help. I don't know if letting the battery die is the way to go? I have it connected to a laptop at the moment. I know they said that the XML file takes a whille, but it has been an hour. I do not have any warranty as this was a trial unit given to me.
I'm not that much of a Noob, but I'm not sure what to do at this point. <<<<---- Fixed using Volume down and Power to do a "battery pull" Although I almost Removed the battery physically.

Can you still boot into the unsafe system?
If so, is the unsafe system currently ICS or Gingerbread?

ICS leaks are not fastbootable.AFAIK, unless you just meant that you were trying to fastboot flash to 6.13.219 before flashing to ICS. Either way, here we go.
Go into safestrap, safe mode menu, then disable safe mode, and restart your droid. I am assuming you at least went into safe mode before trying to flash. If so, this is why we love safestrap...makes sure you have a working OS. Let it boot up. Did it work?
If not, don't panic, there is still another solution, even if you didn't safestrap your unmodified OS (just make sure you do this next time!)
If you did backup and safestrap saved you, ignore this block below for now.
Code:
[LIST=1]Download [COLOR="Red"]VRZ_XT894_6.5.1-167_DR4-1_M1-219_1FF_01[/COLOR].
You might already have this if that's what you were trying to fastboot to. It's 1.18GB in size.
Download is here: sbf.droid-developers DOT org/cdma_maserati/VRZ_XT894_6.5.1-167_DR4-1_M1-219_1FF_01.xml.zip
(change DOT to . Can't post links yet.)
[*]dl.dropbox DOT com/u/76950573/RSDLite5.7.msi Download RSDLite and install it.
[*]Download the Droid USB drivers:
motorola DOT com/Support/US-EN/Support-Homepage/Software_and_Drivers/USB-and-PC-Charging-Drivers
Install them. [COLOR="SeaGreen"][B]RESTART YOUR COMPUTER.[/B][/COLOR]
[*]Turn your phone off.
Hold the two side volume buttons down together, press and hold the power button down.
Hold all 3 down until you get to the bootloader.
Press volume down to get to "recovery", press volume up to select it.
You'll see a sick looking android/red triangle icon soon.
When you do see him, press both volume buttons down at the same time.[/list]
[*]Volume down to "wipe data/factory reset", power button to select (not volume up this time.)
Confirm, delete everything. When it finishes, select "reboot system", press the power key to enter that choice.
Immediately press both volume keys together after the reboot begins and hold them until you see the bootloader menu again.
[*]Plug your USB cable into your phone and connect it to your computer.
Use volume down to select "AP Fastboot", volume up to confirm the choice.
Open RSDLite on your PC.
Press the "....." icon in the program, browse to and select the 1GB+ VRZ_XT894_6.5.1-167_DR4-1_M1-219_1FF_01 you downloaded earlier.
[*]Click "decompress/start flashing". Now wait for half an hour or so.
I believe there will be several phone restarts near the end, this is normal.
You're now back to stock GB. You no longer have to fastboot to this in order to go forward to ICS.[/list].
Now to get to ICS...
Go here. droidforums DOT net/forum/droid-4-hacks/212307-droid-4-utility-updated.html and download the tool. You don't need anything else but the main tool.
Grab your preferred ICS leak. 6.16.217 is the most recent: droidforums DOT net/forum/droid-4-roms/218610-ics-leak-6-16-217-update-zip-boot-img-crc.html
Flash to 6.13.219 if you didn't just do that.(follow the steps in the CODE block above).
Open the droid 4 tool (.bat file) after extracting from the archive. Plug your phone into the USB. Set it to debug mode. Install safestrap 1.09, root the droid.
Unzip D4 6.16.217.zip. Rename boot.img to ICSFIX.img and move it into the droid 4 utility subfolder named \files\
Copy Blur_Version.6.13.219.XT894.Verizon.en.US.zip (leave it zipped.) to your SDcard.
Go into safestrap and make a backup. Turn on safe mode. Reboot.
Reboot into Bootloader, select AP Fastboot. USB should still be connected and the droid utility open. Select option 16. (Errors might occur. This is fine.) Flash your blur.zip from sdcard. Follow prompts on utility. It will reboot, do some animations. When you see the motorola logo, let it do its thing. Once the moto logo fades out, force a reboot (hold VOL keys & power down.) Now hold vol down and press power, boot to bootloader, and select recovery. Press both power buttons when you see the dead sick android logo. Update from sdcard. Select the zip.
Let it flash. It'll reboot.
Open the droid utility. If you flash to another ICS version, UNINSTALL safestrap 1.09, and then install; the new version 2 one. Make backups. Root your phone. Use the last option on the droid utility to flash between ICS versions.
You cannot use it to flash between something like AOKP or CM9 to a normal ICS version (Yes I actually tried this, lol).
Sorry for wall of text, hopefully this helps you in some way, whether you're still bricked, or still want to go to ICS after fixing your brick.

[Q] hard reset

hellppppppppmeeeee!!!!! not me on the phone, the screen stays black, dimly lit, did hard reset with the three buttons, push recovery, I get the android with the exclamation but then when I press vol up + down does nothing for me, never leave me blue lettering with black background, try pressing the button factory and does nothing, still black screen ... dont know what else to do, tried every key and nothing convinations ... I'm about to pull the cell to Toilet

I have had trouble accessing stock recovery on my phone too. You just have to keep pressing in between the volume up and volume down button and try to do this perfectly. Just keep pressing till you get recovery.

Or if you can get to fastboot just fast boot back to stock. There is a thread with instructions in the General forum.

If you follow this http://forum.xda-developers.com/showthread.php?t=2231249 you should be golden. The hardest parts are getting the phone into fastboot (power off, then hold vol up and vol down then hit power, scroll to fastboot with vol down then press vol up) and changing the XML file so it doesn't throw an error.

[Q] HTC One bootloop - can't even reach Bootloader

My phone is stuck in a bootloop, it cannot get past the initial HTC screen, every third time it tries to boot into recovery (CWM) but that only flashes up for less than a second before it goes back to a black screen.
I have been trying to get it to boot into bootloader so i can reflash the recovery but holding Power and Volume Up (and just holding Volume Up) doesn't seem to do it. It's worth noting that whenever I have tried to reboot the phone by just holding the Power button it does not work, the lights just blink forever.
I have also tried running the adb reboot-bootloader command continuously (as quick as my fingers will let me press up and enter) and I can't seem to catch it there.
The phone won't even stay off, it just keeps trying to boot.
Do you have any ideas of things I can try? At the moment I can only think to let the battery run out but it was well charged and has been on USB for a while. I do need this phone to work.
Thanks in advance.
Edit:
The problem occured when I tried reinstalling Android Revolution HD 10.2, I had done this earlier today but wanted to change one of the options in Aroma. Aroma crashed very near the end and the phone went into Recovery, I had some warning but I picked up my phone with the power button so I didn't read it properly.

You enter the bootloader by holding Power and Volume Down (not up).
Try to get into the recovery through the bootloader and restore your nandroid before trying to flash ARHD 10.2 again.

Thanks, I guess I panicked as I should have been asleep. All I had to do was go into fastboot and clear my cache with fastboot (command: fastboot clear cache) and go straight into Recovery and Recovery worked again for any people who encounter this problem.

I experience a similar problem with my HTC One. It recently powered off and I can't start it up again, it's just a black screen and it doesn't react when pressing the power button.
When I plug it into the charger (into a socket or to the computer) it starts booting after a short while. It vibrates, the HTC "quietly brilliant" logo shows up, but then it just goes black again. A few seconds pass and it does the same thing again. Over and over.
I manage to use the Volume Down to get into the HBOOT-screen and there I have 6 choices; Fastboot, Recovery, Factory Reset, Simlock, Image Crc and Show Barcode. I read that I can go into fastboot and clear cache and it might work but I cant even get into fastboot. When I try to press any buttons it doesn't react. If I constantly press volume up or down it sometimes moves the marker, but it seems that it is "pressing" the power button all the time, because when I move it reacts directly to that menu choice. And of course, it shuts itself down after only a second.
It's a stock HTC One, nothing done with it. Recently made a factory reset because the phone locked itself.
What can I do?
EDIT: I had to return it to the store I bought it from, and they sent it on repair to Poland (where HTC apparently has their european base) and they changed the battery. Got it back after 2 weeks and it works fine again!

I have the same problem as you right now but I still can't access recovery I go into hboot and clear the cache with fastboot (fastboot erase cache) but I still can't access recovery, everytime I go on it, it say's "entering recovery..." and the screen goes blank then it goes into boot loop again. Is there any help you can give me to fix this problem? This is my first android phone and I'm really scared that I screwed it up for good.

What if the PC won't recognize the phone while in fastboot? I'm on win 8.1 64. Uninstalled and reinstalled HTC drivers. All I get is a prompt that the device is not recognized. If I try 'fastboot erase cache', it jsut sits there, saying 'waiting for device'. I get nothing listed when I run 'fastboot devices'. Any ideas?

you just need to install HTC sync and it will install drivers for you , later uninstall the htc sync only nor drivers. second try windows 7 or 8 but 32bit version , all drivers will work perfectly. hope it will work.

Nokia 8 force close/ hard reset

Hello guys, I have a major problem with my Nokia 8 on Oreo 8.1 Beta. I've installed substratum with andromeda and used some themes. After some time I rebooted the phone to improve stabilty. But now I can't start it, it goes just to lockscreen and then force closes system UI. I've tried to hard reset it but i can't find or enter recovery mode. can someone please help me, i may reward the one with the first solution. Please help.

Some themes do that i faced that issue back in 8.0. i don't remember how i managed to get into recovery but you need to plug it into your pc. I tried every combination that can be done with 3 buttons and somehow managed to get into recovery, but as i said i don't remember the exact combination.

This did not work for me. I have the exact same problem as the OP and cannot, for the life of me, get into recovery mode. All I did was update to Android 8.1 as the phone prompted me to do and now every time it boots up I get a "System UI has stopped working" prompt.
I've Googled and Googled and no combination of hardware buttons or plugging into the computer has gotten recovery mode to work.

if you have usb debugging activated in the developer settings on your phone you can:
- install minimal adb fastboot and adb drivers on your pc
- plug it in to your pc turned on
- open command prompt in pc, then simply type in " adb reboot recovery" and then the phone should reboot to recovery and you can reset it.

Thanks! Reading the instruction correctly did the trick.
On the "no command" screen: HOLD the power and PRESS Vol+ (press but do not hold).

Try enter safe mode
-Reboot your phone
-hold volume down button
-wait until Vibrate several Times
-after you enter safe mode go to app management and uninstall theme
