General :: Nexus 7 Won't Pass Initial Boot
Dec 25, 2012
Yesterday I got a Nexus 7, but I haven't been able to use it yet. After letting it charge for a while, I hold the power button to boot, followed by a white Google logo on a black screen. After roughly 16 seconds, the screen goes blank and repeats the process. I am able to access the menu that shows the Android on it's back, with the body open with blue buttons. There is no red triangle.
From here, I can select start and it again shows the Google logo - but just hangs there. No difference after minutes of waiting. Same results for Recovery Mode. If the device is plugged in via USB to a charger / computer, the Nexus freezes when reaching the menu, after which I am forced to reboot the device.

First the camera button is unresponsive, and now after owning this phone for about a month, I'm at my wits end! Has anyone experienced this? Last night after leaving the movie theater I pulled my EVO out of my pocket and pressed the power button - the bottom row button lights come on, but the screen does not (battery is nearly full by the way). Pressing the power button makes the bottom buttons turn on and off, but the screen is off. I perform a battery pull, everything seems fine, I can get into the phone after it boots, but once I press the power button to turn the screen off, the screen never turns on again - but the bottom buttons light up like last time. Repeat, repeat, repeat. I have to perform a battery pull every time I turn the screen off. I've now changed the display timeout to 'never' - and if I keep the screen on permanently from the initial bootup, the phone works fine. Absolutely insane. If Sprint can't exchange the phone (due to lack of stock) I'm considering going back to a blackberry. This is my third EVO, and although I love it when it works, I need something a little more reliable.

My G2 Touch refuses to boot up and stays stuck in the initial logo screen. I removed the battery and switched it back on holding down the VOL DOWN button. The display shows:

my nexus 5 is stuck in boot loop ( turning on and off by itself and can't get past the Google icon) and i can't access the boot loader for a reset. all system reset/ factory image guides require me to access the boot loader but the problem is that the phone won't stay in the boot loader because of the boot loop, it turns off as soon as i get into the boot loader.

Is there any app like boot manager that can do so? As far as I know, boot manager supports nexus one, but not Nexus S.

I have tried holding down the volume buttons and power button several times the past three days and nothing. The device vibrates and nothing happens. If I continue to hold the buttons then it vibrates every 6-7 seconds. I also tried to get into fastboot using a toolkit in our development section with no luck. The toolkit says I'm in fastboot when connected, but nothing is on my screen.
At this point I am at a complete loss. If I can't get it to work is that a valid reason for replacement by Google?

When I boot up my Nexus One, it takes <Sandlot>FOR-EVV-ERRR</Sandlot> to mount my SD card. I've got most of my apps on that card, so it's super annoying!
Like I've said, I've got a bunch of apps (40?) loaded on to this card, a few documents, 4 CDs... random stuff. I haven't formatted the card in a looong time... nor have I wiped the phone in a loooong time. I am a crackflasher - I flash a new ROM every day, but I VERY RARELY have issues, so that's why I haven't wiped in so long. I would be happy to just mount the SD manually through the terminal when I need it to.
The phone is a Nexus One. I'm running a CM7.1(or whatever it is) based ROM and kernel. The SD card is the 16gig one that came with the phone.
What's the terminal command to mount the SD card to the phone? So the ROM can access it?

I just replaced my LCD and digitizer on my Nexus 4 after i dropped it and the screen cracked. It was still in working condition after the damage, but the touch screen was unresponsive. The installation went pretty smoothly but when I went to boot it up after it gets stuck at the bootup screen with the 4 bubbles. I tried some of the solutions people found for a similar problem a few months back when Google released Kit Kat 4.4 for the Nexus 4 but none of them have worked for me. There doesn't seem to be any hardware functionality issues, just some software glitch that I can't figure out.

So I upgraded to the nexus 5 and sold my phone to a friend yesterday. He claims that he has not deleted anything and that is froze and just stopped working.
I have the phone connected to my computer where the phones LED notification light is red but will not turn on or even boot into recovery. My computer isn't recognizing it as a device either.
Nexus 4
CM11 (latest update)
recovery is CWM
What may have caused this. and if its bricked how to unbrick it if possible?

I have a Galaxy Nexus with the volume buttons spoilt (not functioning). It is rooted and running on AOKP's 4.4 rom. I accidentally installed the wrong kernel and while panicking, I wiped the data and davlik cache. Now, I am stuck in boot loop. Also, when I plug it into the computer, the phone is UNAUTHORIZED according to adb server.
Is there any way to authorize my phone without booting into the OS itself?
or
Is there a way to boot into bootloader/recovery without authorizing the phone and without using the physical buttons of the phone?

one day when I was playing around with clockword mod and selected restart adbd(I thought it meant the adb daemon but I guess it means something else) in the advanced options area.Well I consider my self pretty tech smart and "advanced" for a 13 year old but I guess things happen. Now when I boot my nexus one the actual boot animation(not splash) is not showing for the first 3 quarters of the boot up. Then I thought I bricked my device because the screen wasn't showing the animation for 20 sec. Then I saw the touch-sensitve buttons light up and then 2 seconds later the animation apeared only for 2 seconds untill my device was booted. I tried overwriting the boot animation in both /system/media/ and in /device/local/ ad it had no effect. I dont know what to do. I am rooted using universal androot because I want to be able to unvoid my warrnaty. So my bootloader isn't unlocked. I am running Cyanogen Mod 6 and am loving it so far! But I am wondering what to do? Should I re-flash the rom? I tried pressing restart adbd again and it did nothing? i have not done a Nandroid restore because it will mess up my apps that are on the sdcard if i restore back. I dont know what to do.

To access the wireless at my university the network is 'open' but you have to sign in (personal user name and pass) via a login webpage prior to actually being connected to the wifi. It's kind of annoying to have to do this every time instead of the phone just connecting to the network.So two options that I am wondering would be possible:
1. best case, somehow it can automatically sign into the network once it is detected (e.g. run a script which enters login/pass to webpage)
2. at least have the user name and pass remembered (i cant figure out how to have it remember logins).
I should note, I have disabled cell tower data transfer (reason I bought the nexus one so I didn't have to pay $30 a month when wifi is everywhere!). So accessing wifi is the only way I get data connection; hence the importance of directly/automatically connecting

I am trying to get a friends Nexus 7 up and running. I recently rooted it and installed the custom recovery using my Mac with this guide while the tablet was on 4.3. All was well, but then my friend was given the option to install the 4.4 Kitkat update. After the update, the tablet has been unable to boot - it simply hangs at the startup animation. I am able to enter the recovery boot loader, and enter options to restore from a .zip, however I have no way of accessing the tablet's memory from my computer to put the original operating system back on it- although I think it could be done from Terminal, I am not well versed in command prompts.

I tried flashing a stock Android 4.2 JB ROM that seems legit. After flashing, I rebooted my device and saw the standard Nexus boot animation. So far, I though all was well. It's not. My phone has been stuck in this constant booting state for hours. I pulled the battery after an appropriate amount of waiting and held down the power and volume down+up button. Instead of booting into Fastboot mode, it went straight to Odin Mode. All I can do with my device is boot to Odin Mode or watch the Nexus boot animation over and over again.

I'm used with my Windows computers to make a genuine unstarted system image (Ghost, now Acronis)
When I have a new computer, I take out the main HDD and make an image or boot with an Acronis boot disk and make an genuine image, can I do something similar with Android devices?
Is EFS the system image or just the system files, restoring an EFS backup is enough to make a device bootable again without Root?
Windows PC suitable for this? ADB I guess...
Perhaps it's not possible because I haven't see any topic about making an genuine image before first start of an new device or restoring a factory image... Every time Root is involved.

I am using Goggle's Nexus One with Android 2.2 installed on it. The device is rooted. I have always been using the "quick boot" application with no issues. Recently (about a week), it stopped working. By "stopped working" I mean that it runs, shown the menu to choose boot method from and when I choose one of the options - nothing happens. I tried choosing multiple times, and still no go. I purchased the "hot reboot" app, thinking it might be a problem with the app, and it doesn't work as well. I installed "busybox" and it told me that my device is rooted but it did not manage to install. It is probably a permissions issue. The "superuser" app seems to work, because when I run it it shows me that "set cpu" gets a root access. I tried going back to backups as long as 6 months ago, but it still did not work.

I turned off my N1 and when I turned it back on it never progressed passed the the N1 boot-up animation. I've taken the battery out multiple times, but it does the same thing. The animation starts up then freezes after ~3 seconds, then the animation starts again and it just repeats. Can anyone help me fix this?

I've tried hard reseting, nandroid restores and wiping all my data but my phone still won't boot. I had cyanogen 6 Rom installed on it and when I turned it on this morning the usual animation came up but after a minute it froze and kept restarting. I then tried all the things above and now it only gets the first solid looking X image and it doesn't move on to the animation. I have a feeling it was Rom manager that caused this as I clicked fix permissions last night.

Maybe I missed this and if I did, can you please point me to the right link but just rooted and flashed to the latest ROM and wanted to know how to add the N1 boot animation instead of what is has now.

I downloaded the bootanimation.zip for the droid 2 and all instructions and tips say:
If your rooted it's as easy as putting it in the /data/local folder!
Well there is a /data folder on my Nexus and it's empty. If I try to make a new folder it says "cannot create new folder" in File Explorer that came with CM6.1. Astro greys out the create folder button. What am I missing? Also I saw that you can ADB push it. WTF does that mean? I know how to do some fastboot stuff, is it the same? Reboot the phone with the USB connected and run commands on my PC?

So I've tried to flash like 3 different ROMs onto my Nexus One and every time I reboot, it just loops the boot up animation. And now when I do a Nandroid Restore, it says WiFi unable to start.

I've noticed my Nexus acting a bit buggy since the 2.2.1 update. Lots of force closes with the launcher. (which is exactly why I shredded and burned my old MyTouch for). After FINALLY getting a THIRD 16 gig card, after the other two got "damaged" costing me so far 25-30 gigs of content, I loading it up with movies and songs for my vacation. I go to reboot and it keeps looping the boot animation but wont boot up. Getting really close to kissing Android good bye as I've had NOTHING but bugs and damaged SD cards and an overall terrible user experience for a year and a half with two phones. I know we're only really two years into development but how much longer do we have to wait for a finished product that I don't have to keep making excuses for? More to the point WTF is going on with the boot loader on my phone and how do I fix it?

All of a sudden my girlfriend's Nexus One is rebooting somehow. She fires up her phone, it boots just fine, after a few seconds when everything is loaded, u can scroll thru the menus etc, it seems to reboot, but real fast, the animation comes up, and 2sec later the home screen is visible again. It keeps doing this.
Any ideas? The phone is not rooted, no custom rom, just a few regular apps form the market installed, nothing fancy.

I have a Nexus one and I have made a bit of a mess of it when loading a custom rom. Previously I'd rooted (without unlocking) the stock (2.2) rom before loading Cyanogen 6, later Cyanogen nightlies and finally eViL-NXSense-v1213. I was rather enjoying the last one but had severe stability issues which I think was due to using Titanium Backup and restoring data. I was in the process of re-imaging to eViL-NXSense-v1213 after clearing the SD card, data and various caches when something seemed to happen to the recovery image. I can get into the boot loader but if I select Recovery it shows the Nexus One logo indefinitely and doesn't respond to the power button being pressed, the same happens if I turn it on from cold.
Is it possible that the recovery image has somehow been corrupted? If so what can I do to restore a recovery image that will enable me to install a custom rom. I would prefer not to unlock the boot loader but will do it if necessary.

I try to understand android boot sequence on my JB (under CM10). I found some docs and there should be specific partitions (boot, recovery, system, cache, data).
My understanding of the boot sequence is now:
A) normal boot:
1) Power ON ->
2) bootloader ->
3) boot-partition where i flashed the kernel aka boot.img ->
4a) system-partition with the OS (libs, UI, etc) where i unpacked over CWM my customROM.zip ->
4b) data-partition, where i unpacked google-apps.zip and installed all the apps ->
4c) cache-partition with user data
B) recovery boot (adb reboot recovery):
1) Power ON ->
2) bootloader ->
3) recovery-partition with CWM where i may unpack all the .zip stuff to proper partitions, or restore from sdcard, etc.
Is this correct? I wonder, because i didn't installed CWM into recovery-partition. It cames from install of CM10 (fastboot -i 0xfce flash boot boot.img), so it must be in boot-partition and not in recovery?
So, next confusion: i looked up to /proc/mtd and i don't see neither boot nor recovery partition here:
Quote:
# cat /proc/mtd
dev: size erasesize name
mtd0: 19000000 00040000 "system"
mtd1: 00600000 00040000 "appslog"
mtd2: 06580000 00040000 "cache"
mtd3: 1a400000 00040000 "userdata"
I did a backup with CWM and loocked the data. There aren't boot, and recovery backups:
Quote:
# ls -lha /sdcard/clockworkmod/backup/2012-10-04.18.49.55/
d---rwxr-x 2 system sdcard_r 4.0K Oct 4 18:56 .
d---rwxr-x 3 system sdcard_r 4.0K Oct 4 18:49 ..
----rwxr-x 1 system sdcard_r 1.6K Oct 4 18:54 .android_secure.vfat.dup
----rwxr-x 1 system sdcard_r 54.6M Oct 4 18:55 cache.yaffs2.img
----rwxr-x 1 system sdcard_r 360.2M Oct 4 18:53 data.yaffs2.img
----rwxr-x 1 system sdcard_r 212 Oct 4 18:56 nandroid.md5
----rwxr-x 1 system sdcard_r 214.6M Oct 4 18:51 system.yaffs2.img
#
So, i think i didn't understand the boot sequence and partition schema corectly.
