[Q] Need Assistance, I brick my Galaxy Nexus

Hi, I am afraid I brick my Galaxy Nexus (Rooted)
Cause:
I think I wrongly delete some system files in Clockworkmod.
Symptoms:
1. When the mobile is turn on, only shows 'Google' logo and the 'Unlock' logo, no responds then.
2. Press Volume + and - key, I can successfully enter recovery mode.
3.Press Volume - key, I can successfully enter Download mode.
4. I do not have any Stock Rom file (or other Rom file) in the mobile memory.
Urgently need your expertise and help.
Many Thanks
(I am not an expert, so would you mind teach me step by step if you got the solution)
Thanks!!!!

So you cannot boot the phone at all past the Google splash screen? LTE or GSM?
Or does the phone boot fine, but you just can't get into ClockworkMod Recovery?

The key piece of information for your symptom is in this line:
1. When the mobile is turn on, only shows 'Google' logo and the 'Unlock' logo, no responds then.
The other lines do help provide background as to the other modes such as recovery and download working properly, which indicates the issue is not *serious*.
The symptom you state, where the device does not boot past the boot logo, usually means the device is not able to boot the kernel or boot past the kernel. The boot logo appears while the kernel is being loaded on the device. Generally, after the boot logo and kernel finish loading a boot animation appears which indicates the kernel has usually handed off to the Android OS to continue booting.
My approach would be to load a completely stock ROM in order to restore a working kernel and ROM to the device. I generally perform this step as a baseline to get everything back in working order.
In many instances the ROM is dependent on the kernel. Your situation requires at least a kernel to be loaded and in order to prevent any further issues, it would be best to load a ROM dependent on the kernel being loaded.
A simple way would be to grab the stock factory images from Google's site and load those back onto the device.
Another simple way would be to grab a stock ROM and flash the .zip through CWM in recovery mode.
Hope that helps!

Since you're rooted I'm going to assume you have ADB and the necessary drivers installed.
1.) Download a ROM. It doesn't have to be stock, you can choose any of the ROMs from the development section for your device. Most of the ROMs are packaged with a kernel already.
2.) Save this ROM file to the same folder where you have ADB installed.
3.) Boot your phone into CWM recovery and plug it into your computer.
4.) Use ADB to push the ROM zip file to your phone (/data/media). For example:
Code:
c:\gnex\>adb push rom.zip /data/media/rom.zip
5.) Use CWM to wipe data, cache, and davlik-cache
6.) Install zip from sdcard and flash the rom.zip.

1. I am using GSM
2. Whenever I turn on my mobile, the 'Google' and 'Unlock' logo appears and then freeze, with no more respond at all
* I definitely mess up some system files, but don't know how to restore it because my PC do not recognize my mobile.
Thanks

I am seeing more and more of these threads about "bricked" nexus's is this an issue with how new the phone is or people not following instructions properly as they are too eager to root their phones?
All else fails flash back to stock and count yourself lucky.

To silow,
Thanks for your advice, but fail
1. I put adb.exe, adbwinapi.dll and fastboot.exe (3 files) under my PC C drive (i.e. C
2. I also put a stock Rom (rename as rom.zip) under C drive (i.e. C
3. Boot phone into CWM recovery and plug it into computer.
4. Use cmd command and type c:\gnex\>adb push rom.zip /data/media/rom.zip
5. It fails , It say "Access Denied" (in Chinese, but I translate it into English here)
6. How do I use ADB (it is a ADB.exe file, When I double click it, it only flash up a few page very fast and nothing happen)
Please assist!

To Joeykrim,
I agree that
"Another simple way would be to grab a stock ROM and flash the .zip through CWM in recovery mode."
But how? (according to my symptoms)

The command I gave you was just an example. I didn't spell out the exact details because I thought that you would know how to do it considering you rooted the phone.
If you put the adb.exe and AdbWinApi.dll file in your C: drive, make sure you copy the ROM file to your C: drive too. In the follow example I'm going to use "ROM.zip" but use the name of the ROM file that you downloaded. Also I am assuming you are on Windows XP.
1.) Boot your phone into CWM recovery and then plug it in.
2.) Go to your Start Menu and choose Run. Then type in "cmd" without quotes and hit enter to open a command prompt.
3.) Enter:
Code:
cd c:\
4.) Enter the following to make sure ADB can see your phone:
Code:
adb devices
You should see something similiar to this to confirm ADB can see your device:
List of devices attached
019B756F0C018012 device
5.) Enter the following command to copy the ROM file to your phone. Remember to replace ROM.zip with whatever the name of the ROM file is:
Code:
adb push ROM.zip /data/media/ROM.zip
6.) Use CWM to wipe data, cache, and davlik-cache
7.) Install zip from sdcard and flash the rom.zip.

To Silow,
You have been very helpful, but I fail.
"You should see something similiar to this to confirm ADB can see your device:
List of devices attached"
There is NO device number shown after the phrase 'List of devices attached'
To recap:
a) Phone is already plugged in my PC, under the Clockworkmod Recovery 5.5.0.2
b) adb.exe and AdbWinApi.dll file are under C: drive directly
c) Also type cmd in 'Run', a black Dos window shown C:\windows\system32\cmd.exe
d) c:\>adb devices
List of devices attached
(But no device number show up, it cannot recognize my mobile)
Pls don't give up on me!
: )

you can't use adb from CWM, you need to enter the bootloader, then try adb or fastboot (edit: wrong!)

Sounds like your ADB USB drivers are not correctly installed. While the phone is under CWM, when you plug it in is your computer attempting to install drivers for a new device?
Download these bare ADB Interface drivers.ADB USB Drivers
Go into Device Manager on your computer and check the device list for any unknown devices or "?" devices. If you need to update those drivers by pointing them to the drivers you downloaded and extracted from that link above.
When the ADB Interface drivers are correctly installed you should see Android Phone listed under under your Device Manager when it's plugged in with CWM recovery loaded.

You CAN use ADB with CWM. That's one of the reasons why CWM is so awesome.

This symptom generally occurs from not having loaded the drivers for the hardware. As with the majority of hardware devices when being connected to a Windows machine, the drivers need to be loaded. Sometimes these are automatically loaded and other times they have to be manual loaded.
As an alternative and for future reference, the android-sdk package contains general USB drives which usually work for Google Nexus devices.
Generally, as this providers a *cleaner* install, best practice as recommended by Google is to download the whole android-sdk .zip and then from the installer download/install the pieces needed, such as platform-tools (containing adb) and USB drivers as opposed to extracting out the adb.exe and .dll file and installing manually.

Agreed. To add greater clarification so there is no confusion: adb can't be used from the bootloader.
The /sbin/adbd daemon on the device is only loaded while in normal android boot mode or in recovery mode as called by the init.rc (or on some older devices, recovery.rc) file in the boot process.
Bootloader mode will only work with fastboot while it is in fastboot usb mode.
On some devices, the bootloader has a separate menu for fastboot and on other devices, the fastboot mode is directly entered when entering the bootloader.
Hope that helps clarify!

To silow (and all other helpers)
1. I fail
2. The ADB USB drivers in my PC should be fine as in Device Manager , I can see Android Phone with Android Composite ADB Interface. (No exclamation mark)
3. On the other hand, whenever I plug my mobile into PC, I can see "Unknown-Full"
4. In DOS, when I first type "adb devices" it shows
* daemon not running. starting it now on port 5037*
*daemon started successfully *
List of devices attached
(but NO device number shown!)
5. When I enter adb devices second time, it shows
List of devices attached (No device number shown)
Thank you so much , but it is Hong Kong time (my place) at 0511 am , I didn't sleep all night and I am very tired.
If you don't mind (especially big helper Silow), please give me email so that I capture screen picture and show you in detail (hope it may help)
my email is
[email protected]
I need to sleep now, I will check my email and see you guys or come back this Forum later (several hours later, as I really need some sleep right now)
Pls don't give up on me as this is an expensive mobile. I think the hardware is fine, just need to figure out a way to unbrick it.
Thanks, and see you!

What you need to do is right click on "Unknown-Full" and click on "Update Driver...". Then choose "Install from a list or specific location". Make sure "Search for the best driver in these locations." is checked and "Include this location in the search:" is check. Click on the Browse button and browse to where you extracted the driver files from the link I posted above. Click Next and this should install the correct drivers for you. Afterwards try "adb devices" again to see if ADB now reconizes your device.

To Silow,
Fail.
1. Already installed the drivers you gave me (and there is no 'Exclamation' Mark) in Device manager
2. Situation is the same , Cannot recognize my mobile (i.e. no Device No. after entering adb devices)
3. "List of devices attached" shown in DOS video but without any number.
No other method?
My mobile is really 'bricked' to death?

To Silow and all,
Something important
1. When choose 'install zip from sd card' under CWM, a list of old folder names remains
(e..g gameloft, DCIM, Pictures, etc). That means almost all old files, folders are STILL in my mobile!
2. I have already use the funcion 'Wipe data/factory reset', 'wipe cache partition', ' Wipe Dalvik Cache'
Perhaps my CWM has problem?

What happens when you update drivers for Unknown-Full?
Boot into fastboot and see if your computer recognizes the phone by checking device manager. The key here is to get your computer to see the phone either in fastboot or CWM.
Perhaps try another cable, USB port, or new computer.
The goal is to get Android Phone ADB Composite Interface to show up in device manager either in Fastboot or CWM. Without that done you cannot use Fastboot to flash nor ADB to push a zip file to the phone.

[Q] ADB recognizes device but not in recovery

Hi! I want to update my girlfriend's GNex by pushing update via recovery. I have adb working and recognizing device when it's turned on (with debugging mode). But when I go to recovery (adb reboot recovery), I can't get my device recognized again - "adb devices" shows nothing. I figured it can't be problem with drivers (since the device is recognized when turned on?), I must be doing something else wrong? But I have no idea where to look.
Sorry for the (probably) common question, but all I've found (using search) is adb not recognizing devices at all. I've been only using "fastboot" commands so far, and I never had problems with recognizing.

what recovery are you using? in twrp, in advanced menu, theres a adb sideload option.

The problem is that her phone is locked, everything is stock. The only option is adb sideload (as far as I know). Any suggestions? I really don't have a clue.
Sent from my Galaxy Nexus using my thumbs.

Stock recovery does not offer the ADB interface, so adb commands will not work. You need to flash a custom recovery such as CWM or TWRP.

Ahhh, I didn't know that. I guess I have to wait for the ota, then, since I can't flash or use custom recovery. Thank you for your help!
Sent from my Galaxy Nexus using my thumbs.

Actually you can use adb commands in stock recovery - this works on build number JRN84D and newer only (JRN84D corresponds to 4.1, the first Jelly Bean build).
1) Reboot your device into the stock recovery (i.e., the screen with the Android on its back with the "!");
2) Access the stock recovery menu by pressing power and volume up;
3) Select "Apply update from ADB";
4) Download the correct update for your build and place it in the same directory as your ADB binary;
5) Open a command prompt in the same directory as your ADB binary;
6) Type adb devices to make sure that your device is recognized;
7) Type adb sideload name-of-file.zip
8) Reboot. Done.

Can you ADB push files to the sd card without an OS installed???

I just accidentally wiped my SD card and my system and now I don't know how to get a rom onto my phone due to the lack of an SD card slot. Can anyone help me get a rom on the internal so I can flash? I have TWRP still but I have no clue how to get a rom to my sd card. Am I screwed? Cause I read a forum that had to have usb-debugging on and I have no system lol. Thank you guys so much

You dont need USB debugging tot have adb in recovery. Just use adb sideload. Or adb push.

Could you give me the commands to adb push a rom to the phone? I can't get adb to recognize my device in fastboot either When I use the fastboot devices command no devices show up... it's depressing

First use TWRP not fastboot. Once you are in recovery plug the phone in and type "adb devices" (without the quotes) in command prompt or terminal. If it returns with letters and numbers (can't remember might be a combination of both) your good to go. Type "adb push c:\downloads\Rom.zip /sdcard" type out the directory where the file is instead of downloads change it to where your rom is. If you type adb devices and nothing happens you need to work on your drivers.

I had this issue - I couldn't get the computer to recognise the phone when it was in the Bootloader. I had to uninstall all the android drivers I could find (using this: https://www.topnotchtablets.com/FixUSBproblems) and then plug the handset back into the USB while in bootloader.
Let it detect it as a generic device (or whatever it chooses to see it as, mine was different every time), then in Device Manager, right click it, then select Update Driver Software. Select the option to choose the driver you want to install and navigate to where you have the drivers saved. The actual driver is: android_winusb.inf. Choose the option select the driver yourself from that file, and locate the one that says Bootloader.
After doing all of that I was able to see it all fine, and it was detected in fastboot, and all the toolkits I used.
Someone feel free to correct me anywhere I'm wrong - just going from memory here.

He said he can't get adb to recognize his device - isn't that because the drivers aren't installed properly? I know adb and fastboot are two separate things. If the device isn't showing after he enters "fastboot devices" then my first guess was that the phone, in bootloader (since he has no OS installed), isn't showing up in device manager either because the drivers aren't there.
Excuse me for trying to offer thorough assistance...

Sorry if I sounded like a Douche. I might be wrong but I thought adb and fastboot had separate driver sets.

No worries - it's possible that they do. But the drivers I linked are the ones that worked for me consistently. The Samsung ones seemed to stop working each time I disconnected the handset and plugged it back in via USB.
In any case, those are the only ones I have installed right now and everything is working great for me connection/recognition wise.
Any luck yet jtl_777?
To push files to the handset, use the command: adb push filename.ext destination-folder
Explained further here: http://developer.android.com/tools/help/adb.html#copyfiles

Just for future reference so people reading these threads don't get super confused, your computer won't recognize your phone through adb commands unless you are in adb sideload through your custom recovery, or if you're booted up and running in an operating system. You could also use adb push commands in your custom recovery. This has nothing to do with drivers or whatnot. If in bootloader your device isn't recognized through adb commands, that's completely normal, because it never would be, but your device should be recognized in bootloader with fastboot commands.
IF your phone is NOT recognized in your booted up phone, or in adb sideload through your custom recovery, or with adb push commands in your custom recovery, with adb commands, then you have driver issues.
ALSO IF your phone is NOT recognized while in bootloader, with fastboot commands, then you have driver issues.
To answer the OP's question:
If you have an unlocked bootloader and you are in TWRP, you can mount your phone onto your computer and copy and paste the rom zip onto the phone and then install it through TWRP once on the phone. If that doesn't work, then you can try using adb push commands while in TWRP (or maybe need to be in adb sideload through TWRP) to push the rom to your sd card and then run it through TWRP. If that doesn't work, you can also try flashing the rom zip through bootloader with fastboot commands, but all these commands might be device specific, that's why I won't tell you the commands I know for the HTC One X, but the processes are the same no matter what. Hope that helps

You don't need to be in sideload mode to use adb in recovery. I use adb in recovery all the time on all my devices to push files

I believe that's if you're using push commands, no? Other than adb push commands, can you use other adb commands while in a custom recovery, without adb sideload?
For the sake of clarity, you cannot use any adb commands while in stock recovery, but you could if you have a custom recovery.

How to transfer a zip on my sdcard without adbsideload

I everyone,
I need your help, I tried to install a new rom (AICP : this one) , and somehow forgot to do a backup.
When I boot I only get the swirling logo, never get to fully load.
The phone is not bricked, I can still access the bootloader / fastboot and my recovery, so I could simply flash another rom... but I can't figure how to get the zip file on the /sdcard.
I can't use adb sideload or push, I have HTC sync and android sdk installed, I have no problem to use fastboot commands, so I guess I don't have any driver problem, but adb devices never shows my phone (Tried while off, booted on bootloader, on fastboot, and on recovery, never shows up when I try adb devices)
On windows I get a driver error when plugging my phone while in recovery, but I don't find how to install it.
So... is there a way to mount the /sdcard/ as an external drive in windows or ubuntu ? Or do you have a workaround for adb ?
Thanks a lot !
Vincent

Stuck in Fastboot mode - possible to backup date?

Hi guys.
My dad's phone is suddenly stuck in Fastboot mode, possibly bricked.
Warranty will cover it but unfortunately he has lots of pictures which was not backed up.
When started and connected to my PC the phone is stuck saying:
Fastboot mode started
EDIT: the phone was stock, not rooted.
-- reset--
-- portchange--
Windows detects it as "Android" Under Other devices in Device Manager.
I've tried to update the driver, downloading two different LG G3 drivers but this doesn't work.
Is there any way to backup data on the phone before handing it in?
Cheers

Simply, you need to do;
1- Install proper drivers for fastboot
2- Boot (not flash) a TWRP image for your device via fastboot
3- Install proper drivers for ADB
4- Simply type "adb pull /data/media" from command line
Warning: Do not try to copy files via MTP.
