INSTALL BACKUP!
Or 1. Try pull battery. Or 2. Install again. Or 3. Fastboot.

i made a back up with titanium and android recovery....
i pulled the battery installed it 2 or 3 times and same thing
what exactly do i type in my cmd prompt on fastboot

If you have a copy of the old ROM, why not reinstall?
For fastboot, sorry, but looking for a tutorial.

Sometimes certain roms do not properly either clean up the cache and dalvik-cache before and\or after installation which can cause that exact issue. It boots to the Dual-Core screen without doing anything else or restarting after some random amount of time. Hook up fastboot, connect to the device
in command prompt, type this
first confirm that fastboot can communicate between the phone and the pc by using this command below which should show a device connected and list it's serial number
fastboot devices
#--if fastboot sees your phone then just simply type
fastboot -w
#--that wipes the partitions that can cause you to get stuck at the initial boot screen logo, after it finishes, just type
fastboot reboot
I've gotta out of a few situations where phone wouldnt boot until I either did this "fastboot -w" or in clockworkmod recovery, cleared the data and cache, hope that helps, try this method before jumping to any extreme solutions that could make the phone a hat weight

ok it rebooted and went off the screen now its in a boot loop and flashes the motorola sign then shuts down and keeps going

ok, so the issue was partly the cache not being wiped prior the rom being installed and something went wrong with the installation of the kernel. That happens if the boot.img didnt properly extract and write to partition or its just incompatible with the rom\device.
Visit faux123's thread with kernels for ATT froyo, GB, CM7 & CM9
download the kernel that's compatible for your rom(froyo, gb, cm7 or cm9). Once you download the zip, go in there and pull out the "boot.img" file and put it into the same folder you have fastboot.exe in and boot into fastboot again.
quickly check connectivity with "fastboot devices" to verify and if that checks out, use this command.
"fastboot flash boot boot.img"
it takes like 3 seconds or something to complete so its an easy fix, after its done just do the "fastboot reboot" command.
i had this same exact issue last week plus my recovery was being erased along with this problem so i keep boot.img & recovery.img just sitting inside the fastboot folder just in case
atrix reboot project - it has every single file thats for the atrix and copies of systems, roms, tools, recovery files, mods, tweaks

Try this:
Pull battery
Replace battery while holding volume down until you see fastboot
Tap volume down to until you see android recovery, then press volume up to enter recovery
First try wiping cache/dalvik, if that doesn't work restore nandroid backup, if that doesn't work reflash rom

[Q] Bootloop on rebooting into recovery?

I rooted through cyanogenmod method, then unrooted (went back to stock 2.2.1) with the stock P15100.zip. I had another hardware issue with my phone (microphone failing) and thought it could be software. The mic was still broken and I wanted to root again so went through cyanogen method again flashing CWM. I was able to reboot once into recovery to flash synth's ICS. When I try to fully reboot, then reboot into recovery again, I got bootloop for a minute, then eventually booted into the rom. I tried flashing 4ext and same issue. I tried flashing CWM again from app and still have the issue. I'm just guessing recovery is corrupted and it needs to be formatted and re-flashed? Anyone know how to format recovery via adb and then push cwm or 4ext?
Any help much is appreciated.

You can flash a recovery through terminal emulator. As I recall, the commands are:
su
flash_image recovery recoveryname.img
Sounds like you might be having bigger issues, though. I hope your recovery partition isn't going kaput.
Jack_R1 might have an idea.

Man, Jack_R1 is still around these parts? But as for OP, definitely sounds like your recovery is corrupt. What you want to do is if you have any fastboot/ADB knowledge is you're going to want to download the recovery.img of your choice, name it "recovery.img" then place it in your ADB folder, plug your phone in in Fastboot mode and then type in the following commands:
Code:
Fastboot devices
it should show you a number followed by "fastboot" after this type
Code:
fastboot delete recovery
it should spew out how long it took followed by "recovery deleted" or something like that.
lastly you're going to flash the recovery that you downloaded. Type
Code:
fastboot flash recovery recovery.img
That should do it! PM me if you need any other help

OP, what phone do you have? You're writing a wrong name for PD15IMG.
In any case, if you indeed have PD15IMG - find "root for S-OFF users" thread in Development, get the PD15IMG with CWM from there, flash it just like you flashed return-to-stock package, and boot into recovery. If it doesn't work - it means that it's not the recovery that's corrupted.
And I suspect that you're just not understanding correctly what your phone does, and/or not actually booting into recovery.

I have used adb a bit (for root with cyanogen method). I'm guessing that the delete command will reformat the recovery partition? I'll give this a go when I get home and get back to ya. Thanks for the reply! Is there a way to download the 4ext recovery img file?
Edit:
I downloaded the CWM touch img and connected to the phone in fastboot. Was able to follow your instructions, but the command is erase not delete. When I put in the delete command it came up with the instructions and was able to figure it out. Flashed recovery and I can now boot into recovery every time from fastboot, terminal, adb, and from power prompt in rom! BOOYAH! Thanks a ton!

Hey Jack,
I have HTC Glacier. Was a typo for the PD15IMG name. I think I have a decent understanding of the phone, and most likely have a corrupted recovery partition. Seems that instead of just flashing a recovery over a recovery, I may need to reformat the partition and then flash? I'll try flashing the file you suggest and report back. If it is not the recovery that is corrupted, what else could be the issue? Possibly an issue with the bootloader not allowing the phone to boot into recovery? Thanks for the reply.

Flashing recovery isn't copying a file. When you flash IMG through bootloader, it is flashed just like what it is - a complete image. Formatting the partition doesn't do anything, since it has no "format" - the image flashed by the bootloader contains both the structure and the data, just like a CD/DVD image does, for example.
The possible options I can think of are:
1) Your recovery partition is physically bad - unlikely.
2) Your bootloader is corrupted - could possibly lead to you being unable to enter recovery.
3) Something that prevents your phone from entering recovery - i.e. a stuck button or something - or you're doing it wrong. I'm afraid that what you're describing as "phone bootloops for a minute and then boots a ROM" isn't really a bootloop - because these phones can't get out of bootloop on their own, if booting failed once - it'll fail always. Logcat can confirm this. I believe it's just the ROM that's booting normally when you try to enter recovery, so, in this case, since you didn't specify how exactly you're trying to enter recovery - it seems like you're either doing it wrong, or when you try to enter recovery you're not getting there.
To help people help you, please write down the exact way you're using when trying to enter recovery, and if you know more than one way - try them all (from bootloader, by adb reboot recovery, directly booting without flashing by "fastboot boot", etc). And post your HBOOT version.

Sorry if I wasn't more descriptive. I really appreciate your help and everything you have done for this community. Seems the recovery was corrupted by the 4ext app. I was able to extract the recovery.img from the 4ext download and was able to flash it via fastboot. Everything boots properly now. HBoot is 0.85.2007 FYI. Thanks again!

Updating to 4.3 Image with fastboot failed.

Hi guys
I was trying to update to 4.3 using fastboot and after finishing i got stuck with the google on the screen. So i went on to try it again, this time installing each .img in the zip manually. While i was sending the System.img the usb connection broke and i tried again to no avail. So i was like lets do this again. So i went i started all over again with erasing boot, now the terminal is stuck on that and not going forward. Im out of options. Really need help, im helpless here. Please.

Is that a Mac? There is another thread with a guy having issues flashing system.img using a Mac. Not sure if he was able to fix it or not. He was able to flash all the other images just not system.img.
For reference from Efrant's thread on flashing image files if your phone hangs during first boot try this:
Note that some users indicate that they can't get past the X on boot. If this happens to you, reboot into the bootloader and select recovery. Then, when you see the Android with the red exclamation mark, hold power and press volume up to take you to the menu. Wipe cache. If that still doesn't work, boot back into recovery and do a factory reset.
http://forum.xda-developers.com/showthread.php?t=2010312
I had the boot issue when I first flashed the images and just formatting the cache fixed it for me. I later had to do a factory reset as the phone was reporting the wrong storage size, 8 GB instead of 16 GB and the reset fixed it.
Here is the other guys Mac thread, not sure it will help you or not.

And the thing about cleaning caches is locking and unlocking bootloader does the same. Tried, i cant install recovery and system .img for some reason.
Thank you for the quick reply, seems the like the guy is having the same issue. Will post it there as well.
The issue is to fastboot the system.img

According to this thread when using a Mac you don't flash the system or kernel (boot) images.

Yeah you do. I just did this on my Mac for my Nexus 4 and Nexus 7 last night with absolutely no issues.
The procedure I used is as follows...
1.1) Download the factory image and ensure all .img files are extracted to the "platform-tools" folder
1.2) Boot phone into fastboot mode by powering it down then holding volume down/power at the same time until the fastboot screen appears
2) Plug the phone into the computer via USB cable
3) Open terminal and type: fastboot devices (if it recognizes your phone's serial number you are ready to move forward)
4) Reboot by typing: fastboot reboot-bootloader (I do this just to test the connection but it's not 100% necessary)
5) Flash the bootloader: fastboot flash bootloader /Users/kevin/Desktop/Android/sdk/platform-tools/bootloader.img
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio /Users/kevin/Desktop/Android/sdk/platform-tools/radio.img
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system /Users/kevin/Desktop/Android/sdk/platform-tools/system.img
10) Flash the data partition: fastboot flash userdata /Users/kevin/Desktop/Android/sdk/platform-tools/system.img (Note: this command will wipe your device)
11) Flash the kernel/ramdisk: fastboot flash boot /Users/kevin/Desktop/Android/sdk/platform-tools/boot.img
12) Flash the recovery partition: fastboot flash recovery /Users/kevin/Desktop/Android/sdk/platform-tools/recovery.img
13) Erase the cache partition: either a) fastboot erase cache OR b) fastboot format cache <<== (the second option seems to work better for most people and it's what I used)
14) Reboot: fastboot reboot
After completing step 14 your phone should reboot to the initial setup screen. If you follow those steps vigorously you won't have any issues. If it doesn't work you did something wrong and should start over. If it doesn't work on a second try then I'd re-download the system image from HERE again just to be sure the .img files you are ultimately trying to use aren't corrupt somehow.

In the other walk through flash system image and boot image is replaced by "./fastboot update image-occam-jwr66v.zip". This could help those who are having problems flashing the system image file. I've also seen this method used for windows in that all you flash is the bootloader image then the update image and your done.

-w is to clear the userdata, but the problem is its not pushing the system.img on the phone! Tried without -w and yet the same issue! I have restored my previous rom and madea nandroid for 4.2.2 stock! Might go back to that and try updating ota! Can somebody confirm if i have to lock bootloader and lose root to get an update!
I have no clue why the same steps work for 4.2.2 but not 4.3 image files!

One thing I don't think anyone has mentioned (which may actually be the core solution to this problem for everyone) is that you need to update your SDK Platform from 17 to 18 and you need to install "Android Support Repository" in order for 4.3 to properly flash. To do this open terminal and paste the path to the "android" executable file found under sdk/tools. My path was:
/Users/kevin/Desktop/Android/sdk/tools/android
After pasting the appropriate path into terminal hit enter. This will open the SDK Manager. Once SDK Manager is open it will ask to update outdated drivers. One of the drivers being updated is SDK Platform. Before hitting the update button scroll down to the 'Extras' folder and check the box next to "Android Support Repository". Now hit the update button.
After doing this, reboot the computer (may or may not be necessary) and try flashing again by following the steps I provided in post #5. Let me know if that solved it.

Well, i may try that! But as if now, went to bootcamp, installed drivers and sideloaded 4.3. I may still try updating sdk, just in case i may neeed to do this again!
Where is this sdk/tools?

sdk/tools is located wherever you extracted the .zip file to. In my case I just put it all in a parent folder on the desktop called "Android".

Boot loop / blank screen

so I could use some major help! I received my new nexus yesterday and I believe i've already soft-bricked it somehow but I can't seem to recover it. I've read that you should change the APNs from the cingular ones to the new att settings. I did this, and then I rebooted phone, but somehow it got stuck in a boot loop. so i was like S%^T, and all. so like a moron I started messing around in fastboot and I unlocked the bootloader through cmd line. I found this article http://forum.xda-developers.com/showthread.php?t=2010312 which I figured was my best chance for a recovery. I also tried the Nexus Root Toolkit v1.7.1 and told it i was softbricked / bootloop scenario. I've tried loading the twrp, cwrm, stock recoveries, but evertime I try to boot to the screen is on, but blank. i dont get the android with the !..
NOTHING is working!
I think my major problem at this point is i NEED usb debugging enabled, but I cant get into android gui itself to enable this option.
Believe me ANY help is greatly appreciated and I'll but you a pizza and have it delivered to your home...:laugh:

This should be easy, just put your device on bootloader and use this tool, make sure you have the ADB and Fastboot files with it all.

Done this also. I used the 4.2.2 files for Mako. Then followed the link instructions that I posted from that link.
1) Make sure your computer recognizes your device by typing: fastboot devices
2) Unlock your bootloader (if you have not already done so): fastboot oem unlock
3) You will see a prompt on your device. This will wipe your entire device (including the /sdcard folder). Accept. Note: you use the volume keys to change the option and the power button to accept. You cannot use the touch screen.
4) Reboot by typing: fastboot reboot-bootloader
5) Flash the bootloader: fastboot flash bootloader bootloader-mako-makoz10o.img (or whatever the name of the bootloader image that you downloaded).
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.48.img (or whatever the name is of the radio image that you downloaded).
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system system.img
10) Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
11) Flash the kernel/ramdisk: fastboot flash boot boot.img
12) Flash the recovery partition: fastboot flash recovery recovery.img
13) Erase the cache partition: either a) fastboot erase cache OR b) fastboot format cache <<== the second option seems to work better for most people. Thanks joostburg.
14) Reboot: fastboot reboot
15) Done! The first boot will likely take quite a bit longer than you are used to, as Android builds the Dalvik cache.
At step 8 it doesn't reboot saying it failed and I have to hardboot back into bootloader from every step forward where required. Eventually I can flash all the img files and reboot phone. I'll then see and android logo with a blue rotating sphere and status bar, then reboots. it does this several times then screen goes blank.

Well I was able to run the "flash-all" batch file with success, no errors or bootloader reboot issues. Phone rebooted again and now I'm suppose to be waiting for Dalvik Cache to rebuild. This is about 10 mins ago though, any ideas how long it takes to do this??

Should take around 10-15 min. If its taking more than 20 minutes i would suggest going into the bootloader, then into the stock recovery and doing a factory reset from there.

USB Debugging is just really a ADB switch for the OS.

[Q] Need help! Did OTA update to 5.0, stuck in bootloop!

I need some major help
My N7 2012 was stock, never rooted. I had only installed OTA updates. Yesterday, the OTA update for Lollipop appeared, and I installed it.
It worked fine for about an hour, until it suddenly rebooted. After that, it will now only boot into the launcher (Nova Launcher) for about 15 seconds, then *bam* crash, reboot. Rinse and repeat.
I've tried booting into safe mode via long-pressing on the Shutdown menu, but it apparently crashes before it can reboot, because it just boots back to Nova Launcher.
I've also tried getting it into fastboot, and I can issue fastboot commands. However, I've never unlocked the bootloader. And when I try to unlock it now, I get the screen that says "This will void your warranty are you sure?" But when I select Yes, fastboot's console says "Failed", and it remains locked.
If I go into Recovery, it just says "No commmand"
I need some help from the geniuses on this forum. To me it seems like an app running at startup is causing the crash, so if I could just get it to Safe Mode, I could figure it out and uninstall it. Hell, I'd be fine w/ a total wipe at this point. Just something to get it working again!
Thanks in advance!

Try using wugfresh's nexus toolkit to fix your issue, preferably to full wipe and reinstall lollipop again.

Didn't work

I tried using the Nexus toolkit, using Flash to Stock/Unroot in Bootloop mode, and it didn't work. A few sections succeeded, but most of the sections said "FAILED". Even after performing this, it still wants to boot to my normal desktop, so I know it's not re-flashing a thing.
I wish I knew more about this. I can get into fastboot by going to Power+VOL- but because it won't stay on the desktop, adb commands are a no-go. Is there something in the Advanced section of the Nexus Toolkit that will let me do a reflash? I'm afraid of just poking and trying things for fear of truly bricking it.
Thanks.

Sorry just re-read your last reply didn't realise you can't do adb commands, if you get to a point when you can then below may help...
I had a similiar issue caused differently what i did was to go to this link
http://forum.xda-developers.com/showthread.php?t=1907796
Downloaded the bootloader from JWR66V the guy mentions in his thread he mentions the same issue that i had which is when i tried to flash a stock or custom rom i kept getting messages about invalidstate on bootloader then the system and userdata images would fail when i tried to install...
In the end i downloaded the stock JWR66Y rom, replaced the bootloader image with the one mentioned above, i had to flash the seperate parts of the rom as the Nexus Root Toolkit wouldn't accept the MD5 after i replaced the bootloader so make sure the recovery, the modified bootloader, system and userdata are in your SDK tools folder then i did the following in cmd...
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase cache
Fastboot reboot
And voila it booted up and then upgraded its self and is now stock running 5.0 but its working for 2days it wasn't lol

You can try booting into Safe Mode directly from powered off state. From a reference guide here in help

[size=+1]Safe Mode Boot[/size]
From a cold start boot (press & release Power button), wait 2 seconds after the B&W Google (bootloader) splash screen appears, then press and hold Vol-Down button until the normal OS boot is fully completed (lock screen or home screen appears)

Sounds like something is draining the RAM. Try using the stock launcher as default.

Still crashed

I didn't know that. I tried it, and I was able to boot it into safe mode doing this ... and then it crashed in 15 seconds and rebooted...
At this point, I'm considering just emailing Google, since its their update that did this.

They'll probably tell you to wipe cache partition. And by the way,

that is a normal operation, it's supposed to say that. What you need to do to get the actual recovery menu is, with screen saying No Command, hold the power button, then click the volume Up button, them let go of power.
This will get you the recovery options, where you should scroll down to wipe Cache partition (last one I think) and select it by hitting power. Reboot into Android and see if that helped.
If not in the same recovery menu there's an option to wipe everything, factory reset. that might cure your device but it will wipe your data.
There is an adb command to pull your sdcard data off your device, but I've never tried it in stock recovery. it might work, but of course it will probably require you had turned On USB debugging.
adb pull /storage/sdcard0/ yourcomputerfolder
yourcomputerfolder being a location on your laptop, like a folder on the desktop.
try this command when in recovery, I don't think it works in bootloader. also, if it works it will only backup your regular files, not your installed apps.
if not then just do the wipe from recovery.
good luck.

Still a no go...
So, I got into the recovery menu, and did a full factory reset. After it rebooted, it went right back to Nova Launcher (with my usual wallpaper on there), and crashed as before. Getting into safe mode confirmed that it no apps were wiped. Factory reset didn't reset a thing.
Its almost like the flash memory is stuck on read-only mode. No matter what I do, nothing changes the contents of memory.

That is weird. And I suppose you can't do what 'wakers' suggested and flash the individual partitions since it probably requires an unlocked bootloader, which you already tried to unlock unsuccessfully. I'd say you were up sh-- creek without a paddle, but... Google searching, maybe there's still a tiny bit of hope:
See this discussion: http://android.stackexchange.com/qu...p-after-lollipop-flash-no-adb-and-no-fastboot
to summarize the suggestions:
- try holding the power button for over ten seconds to kind of reset... something
- try sending the command: fastboot oem lock
yes I know you never unlocked but try it anyway, it might go thru where unlock failed.
speaking of fastboot oem unlock, I know it failed but maybe you can just keep sending the command a few times, one of them might go thru.
I'd add another suggestion: carefully remove the back and carefully unplug the battery and let it sit for a while. then put it back together and try booting up.
may the force be with you.

Finally resolved
Thanks to the posters for the help. I contacted Google customer support and they're overnighting a refurb replacement for free.
