Soft Bricked Nexus....other threads not helping... - Samsung Galaxy Nexus

My CDMA Nexus froze....battery pull, boot looped. Recovery restore backup....."error while restoring /data"
Been trying to get back to stock ever since and I can't get the fricken ADB command prompt stuff to work.
I have installed drivers like 10 times, and it shows "Android phone" in device manager when the phone is plugged in with fastboot on.
Everytime I try and do the fastboot commands it just says "error: device not found"

Does it let you mount usb so you can stick a new rom file on it?

does "fastboot devices" reveal your phone?

It doesn't show up as a drive, just in the device manager as Android ADB Interface.
I just restarted my computer to see if the drivers needed that....this time I ran the 'adb reboot bootloader' and I got daemon not running. Now starting on port 5037. Daemon started successfully. Then it still said error: device not found

[Guide] Re-lock and Un-root **3G & 4G** Xoom

##PLEASE NOTE##
These files are from Motorola's Development site and I take no liability with anything that happens with your device if something goes wrong.
DO NOT ATTEMPT TO FLASH THIS FILE ON ANYTHING BUT THE VERIZON WIRELESS MOTOROLA XOOM Z600 (3G MODEL) OR YOU WILL HAVE A SHINEY PAPER WEIGHT!!!!

You're going to need to have the Android SDK installed. You can download it here:
ANDROID SDK - DOWNLOAD
XOOM Firmware Downloads:
[3G|MZ600-HRI66]
[4G|MZ602-HLK75D]
Unzip the files in MZ600_HRI66.zip and move or copy them to the /platform-tools folder in your SDK folder.
Connect your Xoom to your computer. Type:
Code:
adb reboot bootloader
Wait for it to reboot into the bootloader.
Type the following commands, waiting for each to finish before continuing:
Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
You've now successfully flashed your Xoom back to stock. Now it's time to relock the device. Type
Code:
fastboot oem lock
wait for the menu
then press the volume-down button.
Then press the volume up button.
It'll take a minute or so, then reboot. You're now completely back to stock and ready for the update.
So if you are on Three . One you can use this to revert back to out of the box freshness?

Yes. That is correct. This will return your XOOM to 100% stock.

I have already been thru the LNX 0x0004 debacle and it was absolutely no fun whatsoever.
well I got a stuck at moto logo for 10 minutes
I am going to try to fastboot oem unlock, reflash images again and fastboot lock to see if I get out of moto logo

So the HRI66 is the latest version on the Motorola site? I really need to get a grasp of their version numbers.
EDIT:
Never mind looks like HRI66 is the latest version Thanks anyway.
i was thinking that with the change to the bootloader in the 3.1 update we couldn't use previous versions img's. But I am glad we can return to stock and get this 4G update!
I'm following all those steps directly. Once I type in adb reboot bootloader, it says starting Fastboot protocol support. Once I try to type any other command it says not recognized in adb. Any ideas?

Did you extract all of the files in the ZIP into the 'tools' folder? The same one that adb is in.
Could someone help me,
After the rebooting device I got this massage :
Failed to boot LNX 0x0004
Starting RSD mode 2
Then stuck on Motorola logo. I can't enter the recovery mode.
What should I do ?
My Xoom is H.6.1-38-9 International version

This is what I was afraid of..... try searching the error you are getting. Not many options on how to fix.
i am curious about the LNX 0x0004 error. I know it comes from trying to relock with non-factory img's but what exactly does that mean? I am curious what actually causes the device to soft brick.
Finally I made it, .
I can enter to bootloader by fastboot method, flash the stock image, then relock my device.
Kinda having the same issue as dchurch... "adb reboot bootloader" reboots Xoom to the "M" logo with "Starting Fastboot protocol support," but I can't continue with nay further commands. My computer no longer recognizes the presence of my Xoom and my Xoom doesn't progress past this screen. I can boot it normally with no problem. I've extracted all of the necessary files into my platform tools folder with adb.. any input?

You can try manually going into fastboot as well... there are two ways to do this:
No matter what, power off the Xoom. Then, 1) Power on the Xoom and as soon as you see it turn on (within a second or two of the power on), press the Volume Down button, which kicks it into Fastboot. 2) If you miss the 1st couple of seconds and press Volume Down after 3-5 seconds, it will say "Android Recovery." You can then press Volume Down until you get to Fastboot, then press Volume Up.
My guess is that you have a different issue, something to do with your Fastboot image. Not sure if booting the Xoom into the OS and connecting with USB Debugging on will work or not to flash the files, perhaps maybe just the boot.img?
I also believe that when the Xoom says "Starting Fastboot protocol support", it is in fastboot mode and you can send the fastboot commands to the Xoom. If your PC does not show the Xoom as a device in your PC's Device manager, then you will probably need to load new/correct drivers onto your PC.
Did you make sure that adb recognized your device? Adb devices in the camaned prompt

Device not recognized

I have a pretty big problem and need some guided help. My stock samsung usb charger sometimes charges the phone and sometimes does not. Tried multiple different chords and got the same results, sometimes works sometimes does not. So now I am assuming this is an internal hardware problem soo I decided I should flash stock images, unroot and relock the bootloader and here comes the worst problem.... My device is NOT recognized when I connect it to my PC... therefor I can't access adb connection to flash stock images so I can return it to VZW....
Not sure what to do next.. any suggestions would be great...
It sounds like you just don't have the drivers installed. Just install the Samsung drivers here.

I tried that. uninstalled the old ones (that worked for 3 months) reinstalled them again and still no luck..
Do you have any other Android processes running on your cpu? Droid Explorer or alike? Droid Ex **** blocks adb; I had a frustrating few minutes once when adb wouldn't connect to my device until I realized DE was running in the background.
Long shot, but just a thought.

fastboot is like adb. You need to run it from a command line. You should have had to use it when you installed a custom recovery ('fastboot flash recovery customrecovery.img') or unlocked your phone (ie 'fastboot oem unlock'). fastboot is part of the android sdk (think it's in tools folder, but I moved mine so am not sure).

That's what my understanding of what it was too. I'm in the bootloader running a command prompt through windows and for the first time I think it recognized my devices. I ran 'fastboot devices' and a bunch of numbers on one line came up followed by fastboot. So I think my device is recognized and I can flash stock images?

yes, you can download the images for your device from google and flash them to your phone using fastboot if you want. I'm pretty sure that would put you back at stock with an unlocked bootloader.

I know how to. It was just your demeanor and wording/phrasing that had me confused.
I have the same problem, fastboot was working this morning, now after flashing Revolution HD, typing "fastboot devices" in CMD doesnt return anything anything, neither does adb push command which replies failed to copy .... As if the phone doesnt exist or its not attached. Does the phone need to be in clockwork mod? or just boot the phone normally?
Edit: This should do the trick, open CMD in Windows, navigate to your c:\android where you have fastboot and adb stored and type:
:cd %:h
adb kill-server
adb reboot bootloader

I once knew a thing or two, something about echo and such, but that was a long time ago.

START fastboot flash boot boot.img etc...
save it as .bat in your fastboot folder
should work
since there is no wait-for-device on fastboot, you'd probably have to do something like this...
Code:
adb reboot bootloader
sleep 15
fastboot flash boot boot.img
fastboot erase cache
Otherwise the adb command would return the moment the command is sent to the phone and it'd try and execute the fastboot flash command before the phone is actually in fastboot.

Makes sense, thanks I will try, hope it works.
Thanks to both of you !
I would use a pause command in the batch script on Windows so that the user can make sure that the phone is actually in fastboot USB mode prior to running fastboot. Sleep is not provided in the default command set on Windows so won't work.
Having said that ignore the above para if your script is running on an Unix environment.
Code:
adb reboot bootloader
timeout /t 10
fastboot flash boot boot.img
fastboot erase cache
try this one, timeout is built in since windows 7 i think
hmm my Windows 7 had sleep, must have been installed by a third-party app then if it is not included by default. Noted.

The windows resource kit must have been installed on your PC? Anyway, it can be downloaded from here.
Any idea how to do something like this?
After running the batch it shows a message saying something like.

After plugging in the phone you press the button and it executes the bootloader command, then it says.

[Q] Can I downgrade 10.3 with Windows?

Hello,
Still working on my kids KF2. I got root, yeah! However at some point it updated to 10.3. Can someone point me in the right direction for getting its bootloader downgraded from a Windows 7 x64 platform? I can use a RHEL box at work if I really need to, but rather not.
so I get CM on this thing
thanks!

That is a command to be run from the command lint to put your device in fastboot mode without a factory cable. Once your device is in fastboot, then you can continue with the fastboot commands. If you are in fastboot and you still get "<waiting for device>", you need to make sure your drivers are configured properly.

fastboot never start after update to android 6

Hy
I had an unlocked bootloader phone. Yesterday I flashed the new Android 6, Europe version from the Huawei blog forum, no beta, on my Huawei GX8. I used the method, dload on SD card, Phone off an the press Volume down+volume up+Power button.The flashing was normaly.
Now the phone starts normaly but I can´t start fastboot. When the phone is off and i press Vol down + Power the phone start the android system and the Huawei logo is coming not the fastboot Modus. I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!
Should be connect the charger cable to the phone.
charger or computer

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.
i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

Many thanks for your help, now I m in my bootloader.

2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.
