[Q] Nexus S not working... - Nexus S Q&A, Help & Troubleshooting

I'm going to probably get a lot of hate for this because there are a ton of forums that might get me here. I did search for about 3 hours tonight and discovered some things but am still confused. I hope someone can help this be more simple. So a friend has a Nexus S that isn't working (I have a Nexus S by the by too). It's unlocked but no ClockWork on it. I can press volume up and power to get to fastboot mode. When I click on "reboot," the phone will just loop on the Google logo. If I click recovery, it starts to boot then shows the triangle with the exclamation mark. From there, I can press power and up or down on volume to get the blue screen which says reboot system now, apply update, wipe, wipe. You get it. I'm stuck...I can also turn off the phone, hold volume up/down and plug in the usb to get to "downloading..."
I want to get this phone working and back to stock. I have the SDK Manager (my phone isn't rooted so I use it to take screenshots) and pda net (which I still don't understand why or how to use with this) and two versions of Odin. It seems like Odin can get this working but I can't get it to work or find a clear guide on how to use it and which ones to use. This is a Tmob Nexus S, I think the i9020. Any help would be so greatly appreciated and I will give you all the credit. Oh, and i can pull up the device on ddms with the sdk manager and can explore the files but there is nothing. I can't find a way to drag a file on the phone to "apply update from /sdcard." Sorry again and thanks again!

It seems your boot.img file either corrupted or missing.
Find a working copy of file, flash it via ADB interface or fastboot. Flash recovery file CWM. If that doesnt work, Try flashing CM7 Rom or someother ROM.
Did you check http://forum.xda-developers.com/showthread.php?t=895545 ?
Odin should be your last resort, if nothing really works for you.
If you want to return to stock, simply flash the NAND backup found here: http://forum.xda-developers.com/showthread.php?t=884093 .

Thanks so much for the quick reply. I think I've made some headway...I can "see" the device with cmd by typing adb devices. After that though, I don't understand how to get the stock nexus s rom on the phone. How do I move that file to my phone (what's the line of code I type)? I've tried "adb install <c:\grh78> but it says the syntax isn't correct. Any more help is so greatly appreciated and I appreciate the already prompt response. Thanks!!!

Download your rom of choice (stock, custom)
Flash Cwm via fastboot if you haven't already
Boot into recovery.
Use adb push to push your zipped rom to the sdcard (adb push file.zip /sdcard/file.zip)
Use cwm to flash this zip.

Wow fast responses. I bet it's annoying to help yet another person having issues (again, phone was given to me like this but yeah...) while you guys or gals already know how to do these things very well. Here's where I'm stuck. I enter this code in cmd:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
and it just says < waiting for device >.
Here's a pic of the screen that I'm on with my phone when i enter the command.
http://imgur.com/Pey3W
If I'm just in the first screen by holding volume up and power, the computer won't read the phone. So I click recovery, the screen shows it's trying to install something then the triangle exclamation mark, i press volume up/down with power and get this screen and the computer can "see" my phone on cmd.
How do I get this flipping clockwork on this phone or get the stock image on my sd card? Thanks again for helping me out guys. I have taken a look at the links you have sent me and that's where i found the download as well as the code to enter. I will keep looking at them but if you find a faster solution, please let me know.

One more thing to be super clear on...when I'm on the screen on the Nexus S that says Fastboot Mode on top in red and Lock State - Unlocked...my computer won't read the phone, therefore I cannot fastboot the recovery img...

So you already tried "fastboot devices" while in fastboot mode?
Edit: Actually it sounds you really want stock so download the complete stock OTA ROM (including boot.img etc.), rename it to update.zip and put it on the root of your sdcard. Boot into the stock recovery like you did already and hit apply update.
EDIT: Go here to download the correct OTA http://forum.xda-developers.com/showthread.php?t=1056062
Find the correct 2.3.6 "Full ROM" for your phone model. Sounds like in those instructions you don't need to rename to update.zip. Haven't seen stock recovery for a while so I don't remember.
If there is a wipe option in the stock recovery then do that first.

Yes I have tried fastboot devices in fastboot mode but nothing because my computer doesn't read the phone in that mode. And yes, I want to put the stock rom on there but that's the key, I can't get access to the root of my sdcard. I can't push anything into the sdcard to flash it. Any ideas what to type or how to access the sdcard? Thanks a million, billion.

Also, I can't get the phone to boot at all, like I can't get passed the Google Logo if I reboot so I can't access the sdcard in the traditional way.

Connect with adb and type this:
adb shell mount /sdcard
Then type:
adb push rom.zip /sdcard/update.zip

If fastboot devices returns NOTHING then this is most likely a driver issue. Remove the device through device manager, make sure you have a recent SDK (for the USB driver) and let it re-detect.

If you can get into the boot loader and get a proper USB driver you should be able to flash a recovery.
Once you've flashed Clockwork Mod (recovery) you'll be able to push to the sdcard using ADB or possibly mount the sd card through the CWM menu (although I've yet to have that work).
In order to get a recovery flashed though you need to get fastboot to see your device (unless you can already boot into recovery, then just use ADB).

If he's stuck at the Google logo and has a trash boot.img it's not likely he'll be able to get a shell via ADB. Now, if the system is hanging starting a device or looping during boot then that's possible.

He said he can access stock recovery and has connected with adb, unless I read wrong.

Indeed - I saw no clockwork and figured he'd toasted his recovery image as well, but it does look like stock recovery is there. ADB should push fine to the sdcard from recovery then.

More...so if i type in adb reboot bootloader in the recovery screen, it does just that...great. But then my computer makes a noise, a double tap if you will...like a dun dun, like something didn't work. When you plug in something to the computer it usually goes like dun na...but the phone clearly won't read when I'm in bootloader/fastboot mode. So when I type a command, nothing will work...

That noise is that it detects a device has been connected (assuming a recent version of windows). If you want to flash CWM you need to get the driver sorted for the device. No amount of plugging/unplugging is going to fix it.
If you have the stock recovery you can boot into the stock recovery, use adb to push the full OTA package to the sd card and then just flash that from the stock recovery.

Go to the stock recovery like you have done before and type the adb command I wrote above.

Thanks is all I can say. Okay so when I type in the command, this is what I get:
- exec '/system/bin/sh' failed: No such file or directory (2) -
the "stock recovery" I can get into is the picture I posted a link for. That's what I can access as well as the fastboot mode when I first turn on the phone with volume up/power. But when my computer makes the noise that it's connected (using Windows 7 64bit) it makes a different sound then the normal "device connected." Like it's corrupted.

by the way...if we can get this working, I'll post a picture of me holding the fixed phone!

Updated to RC33 and no longer can enter recovery mode?

Hey all, I had the rooted RC30, and just updated to the RC33. The update itself went fine, but when I am trying to go back into the recovery mode to apply the radio rom update, I cant get the phone to go into recovery mode anymore. I hold the home and power and all it does it cycle the G1 screen. Then boots normally. Anyone have a idea whats up?
Anyone? =/
Ok Im running out of ideas, I tried booting into recovery mode without the memory card inserted, still goes in a reboot cycle and will only boot into the normal mode, wont go into recovery, so I am really confused now. Any advice or so how to get things back to normal would be great please.
try going into the terminal and typing reboot recovery
This just happened to me to i really need help i dont know whats goin on just started... could the phone be possibly bricked? O yea and that process didnt work Tubak is there any other ways to get into recovery mode
Can you boot into the SPL (hold camera button while powering on)? If so, you can fastboot flash the latest recovery.img (from the JFRC33 1.42 build), and that should get you going.

Says "Operation not permitted"
as for holding down the camera button and powering up, I can get into that screen. So your saying just to reflash the pack I just updated with again? It wont wipe my phone will it?
But yea, would be nice to get things going again. Also oddly when I boot the phone up, normally process media is asking me to either wait or force close. Sometimes another app will be listed as well. Anyone else have that on bootup like if the phone has too much starting up with? Btw thanks for the replies so far. =)
did you run the reboot command as root? if not run it as root, sorry i assumed you knew to but i didn't specify so it can be confusing. also as daveid said you can always try to fastboot flash the recovery image

The response was "Can't open reboot" when I did su reboot recovery
(Edit: Scratch that I feel stupid I wasnt in # mode yet, the reboot command worked however it did the same thing, cycle the G1 screen, rebooted again and booted normal)
Also again on the flashboot, so I use the same file I used to upgrade to rc33? Also it wont wipe my phone would it by that method?
Edit: So if its not too much trouble by doing the fastboot what is the real method of using this? Also which file am I using and will it wipe? And is there any other possible reasons why this could happen that it didnt go into recovery mode?

You will want to extract the recovery.img from the JF update.zip to wherever you have fastboot installed. Then you will enter a command prompt, change to that directory and issue "fastboot flash recovery recovery.img"
If you need further help see the sticky here.
Ok been a lil while since I went back to this issue.. (Had my phone suspended so wasnt using it) Just got it back running after a month.
I looked at the sticky, but Im guessing Fastboot wasnt installed? So to install it, do I just need to put the fastboot onto the memory card or so? Guess just need lil help cause hate this.. since I cant get into the real recovery, but I can go into the other one.
before u updated to jfrc33 you shouldve done this
if u followed directions on the thread it would worked
so this is the only way i see possible to get the recovery program back
u have to go back to rc29 and then re-root and install the recovery image
Rooting your RC29 or lower phone:
On RC29 phones and lower, anything you type into your keyboard is also being run in a hidden console with root permissions. More information regarding that at the bottom of this post. But, to get root access, do the following:
Instructions:
1. Download recovery.img and copy it to your SD card (see the previous instructions on how to copy from your computer to your Phone's SD card).
2. Download the Hard SPL and copy the zip file to the SD card.
3. All files must be on the root of your SD card.
4. Restart your phone. Wait for your phone to start up fully and show the home screen.
5. After your phone starts up, hit the enter key twice, type "telnetd" and press enter. (Yes, it will start up a contact search, don't worry. Just type it.)
6. Download an Android "Telnet" application from the Market and connect to localhost.
7. If you connect successfully, you will have a root prompt "#".
8. Type the following into Telnet (these commands will give you root access easier in the future):
* mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
* cd sdcard
* flash_image recovery recovery.img
* cat recovery.img > /system/recovery.img

edit:
check my sig for the jf tutorial
"unlock your dream"
Question tho, I already had jfcr installed w/root before I updated to the newer version, which I was told was fine. I still have my root access atm as well since I use root only apps.
I can still access the other mode by holding down the camera button. So your method your suggesting, is that what I really need to do or is it something else based off this info?
Alternatively, you could push recovery.img to /system using adb.
The init script will reflash it automatically.

adb? Explain some more please? ^^
edit: Using the terminal, ok I saw some similar commands. Ill give this a shot once I get home with my PC. Anything special I need to prep before I do it or just put the img file in the sd root dir and do the adb command for push?
Ok good news. I was more nervous about toying with things I dont know 100% however I sat down a lil more and figured out everything that was being said. The fastboot flash recovery recovery.img worked.
This posted helped ALOT.
http://forum.xda-developers.com/showpost.php?p=3083753&postcount=1
I was under the impression at 1st however that it was done all via the phone itself and not the PC. So thats where my orig confusion started. However I am now back into my recovery mode and can go back to updating my phone. =)
One quick question tho, after I got the PC to be just the ADB interface, how can I get to mount it to my PC again as a mass storage device? Just redo the drivers again? Or is there a way to swap easily between the 2 modes? (I can use a memory reader so its not a big deal but thought id check)

[Q] Nexus s 4g locked up

Okay, first of all I know, I'm a total noob. I have followed these forums a long time and have successfully rooted a few phones. One of which was my nexus s 4g. I was trying to unroot the phone so I could get ics. This is when I ran into problems and right now I just want to be able to get my phone working again. Right now I am stuck on the Miui boot up screen and no matter how long I wait it stays on that screen. If I do a battery pull and hold down power and vol up I can get into the bootloader screen with the information as follows: fastboot mode, product name-Herring, HW Version Rev 34, Bootloader version-D720SPAKE1, Baseband version-D720SPAKE1, Carrier info, SPR, serial number-37308B81276A00EC, Lock State-locked. Then the different options I can choose are reboot bootloader, reboot, recovery, power off. If I choose reboot, it takes me back to the mius screen and stays there. If I choose recovery, I get the triangle with the exclamation point. I then hold power and up volume again and I get a screen that says Android system recovery <3e> with reboot system now, apply update from sd card wipe data/factory reset and wipe cache partition. I have tried all of these as well with no luck. When I go to apply update from sd card I get matrix-cfs_v15.5 zip, root.zip, update.zip and then what looks like apps such as Alarms/, Android/,MIUI?, etc. If I try to select any of the first ones such as matrix-cfs_v15.5 zip, I get Install /sdcard... , finding update package..., opening update package..., verifying update package..., E.signature verification failed, Installation aborted. Then it gives me the system recovery options again. Any help would be appreciated.
Did you try ADB fastboot method?
Not sure how to try that
I tried doing the adb, followed all directions and installed and when I go to the command prompt and type in anything, such as, adb reboot bootloader I get, adb is not recognized as an internal or external command, operable program or batch file.
ok I got that working now but when I type adb devices and press enter I get a message saying List of devices attached and then it doesn't show anything and I get the command prompt again saying:c:\android\android-sdk\platform-tools>
also since the phone is stuck in either the miui screen or bootloader I can't get into it to put it in usb debugging mode. I am trying on my own to get this going and am stuck any and all help would be very much appreciated.

I think that means you have a locked bootloader.
And from what you're telling, I believe you have stock recovery.
Also, when you're in fastboot mode, I don't think adb commands apply. Use fastboot commands instead (i.e. fastboot devices).
Search for guides showing you how to install and use fastboot.
I did fastboot as well and the problem I think I am having is it's not recognizing my phone because usb debugging wasn't turned on before it locked up. How would I get it to recognize my phone or download an img to my phone if it is not being recognized. Sorry if this is a stupid question.
You don't need usb debugging in fastboot mode.
You either:
1. Don't have drivers installed.
2. Don't have fastboot installed correctly.
You really need to read a guide or two, through and thoroughly.
Bc it sounds like you have no clues.
Yeah dude. Take a step back and go over what you have installed and where you installed it.Yes, fastboot commands start with fastboot instead of adb. And you're on stock recovery.
Thanks for the answer that I don't need usb debugging in fastboot mode, I wasn't sure of that. I have downloaded and installed my drivers multiple times and when I use the device manager to update drivers it says I have the latest drivers installed already. Whenever I do fastboot commands I will type in fastboot devices and shouldn't my device serial number come up? It just gives me the line c:\android\android-sdk\platform-tools>
And is waiting on me to type a command in. And yes I have been looking at guides all night. I appreciate any help you guys might have and remember we were all noobs at one time.
The zip in this tutorial should help.
It has adb, fastboot, and the drivers needed.
And unlock the bootloader because it is locked.
Finally got it, I had everything downloaded that I needed already, but looking at different forums, etc, it seemed like everyone named it something different. So I just used the one link you gave me and did it exactly the same way and it worked. Thanks so much! and again thanks for your patience.

[HELP] Nexus S can't boot recovery

Hi all,
Been given a Nexus S i9023 by my brother who has been "tampering" with it and now it seems a bit messed up.
When booting up - it gets stuck on the "Google" screen with a padlock on it... I can get into fastboot and I can flash recovery but when I attempt to load any recovery - I get that same Google screen with the padlock! I've downloaded a stock rom and even flashed system etc via fastboot but that still gets me nowhere past the damn padlock!!
I've tried to "fastboot boot recovery.img" and I still get the Google screen with the padlock but it says "Fastboot status - OK" on the bottom left.
I've searched and searched but everyone just seems to give tips on how to flash recovery. I know how to flash recovery; it just seem to be going into it though! Could the internal memory be screwed?
Thanks for any advice!
Sounds strange for sure. You try from within the OS? Enable USB debugging and adb reboot recovery.
Doubt it will work but its worth a shot

The phone stops at Google with the padlock on boot! Can't even get into the OS. Going to try to unbrick it and Odin but left my ubuntu laptop at my parents and can't be bothered to go get it... couldn't get it to work booting off cd rom. Kept giving me the "SBL Injection Failure Failed to find device" error booting ubuntu on a CD!
You may have a storage issue.
I seen you tried to flash system and boot recovery with fastboot ( which should have booted) but did you try to flash them all and wipe. The command is fastboot -w update file name.
I think Odin is a windows only tool anyways by the way.

No idea why I said Odin - I meant the unbrickable recovery thing.
I tried Odin with a Jig last night; got it into download mode and flashed with odin. Got the same result.
fastboot -w also gives the same issue...
If I have a storage issue - is there any way I can tell?
Basically you can tell by the issues you're having. Doing all the proper stuff to flash images etc and still having a booting/working device.
As far as a actual diagnostic tool I don't know of one. But it sure sounds like a hw issue to me.
I have the following problem: since a few weeks I'm unable to enter recovery.
This is what I do:
- shut down my phone
- press the power button while holding the volume up
- than I get a screen where I can choose from 4 options using the volume controls and selecting an option with the power button
- I select 'Recovery' and press the power button
- I get the usual black screen with Google logo and padlock
- but instead of getting into my recovery, I get a black screen with a Droid lying down, the 'chest' opened and some kind of small warning triangle above it..somebody who knows what I have to do??
Thanks in advance

You need ADB (and ADB drivers installed, strongly recommend PDANet Android Drivers) and fastboot executable.

When u boot on the Google screen on the bottom centre does it have a padlock? If so then it is unlocked.
You are entering recovery. Stock recovery
If you want a custom one either flash with fastboot or if you're rooted with a app. Goo manager. Rom manager etc.
Keep it mind that if you're on a stock ROM the custom recovery gets overwritten back to stock when the phone boots up the os

You need ADB (and ADB drivers installed, strongly recommend PDANet Android Drivers) and fastboot executable.
Custom recovery I suggest you use Clockworkmod Recovery.
I imagine your phone is already unlocked?

In installed the drivers and I installed the fastboot executable, but what do I have to do next? If I run the fastboot.exe, it just quickly shows a CMD-window and then disappears.
Edit:
I just discovered that, when I'm at the bootloader (I think it's called that way, the screen where you can select recovery), and I choose to reboot, I get the same 'error' as when I try to enter recovery.
Edit:
Alright, I was able to flash a new recovery, using cmd, but now when I try to enter my recovery, the phone gets stuck at a black screen with Google logo and padlock...
I have same problem as wolverine_2k who made the post. My nexus, can't start, I tried reboot and recovery but didn't work. After reboot or recovery I see Google logo, than Nexus screen and that is it. It didn't move to home screen and it stay with lighting screen all the time till I remove the battery. I can't power off it and don't know what to do. I can't transfer data with my PC (it don't recognize the device - only notice that "unknown device" is connected). Please any ideas?
P.S.: My English is not good, if someone answer do it simple please
Thanks!

[Q] Please Help, Xoom eternal loop

I have 2 Xoom tablets, in Germany, and I took the SD Card from one of them to put it on a new phone, the Tablet kept working fine until last week that I forgot to plug it and the battery ran out. When I charged it and started it, it didn´t work again, I got the Encryption message, nothing happens when I click the Reset Tablet either, I tried putting the SD card from my other Xoom but still nothing. I enter the Recovery mode and did a Factory Reset and the tablet was OK.
Battery run out again yesterday and got the same problem once again, but now factory reset is not working, tablet stays stuck at the "M" logo after doing it, I have repeat the operation a zillion times and nothing, it stays on the M. Plus I can´t turn it off either.
The model is the MZ604 and Android Version 4.0.4
I connected the xoom to the computer after installing the drives but it won´t recognize it. I got to do the fastboot and flashed motorolas images but nothing. I can´t do the adb reboot bootloader command because ADB won´t work, because I don´t have USB Debbuging checked, but I can´t check it now because I can´t get to settings (
What can I do to recover the tablet?
Anyone, is driving me crazy, no matter how many time I flash new images it always stays on the original, so I can´t flash any special recoveries either
I tried RDS too and after the reboot stays the same in the M logo, nothing changes. What can I do?
No ideas? :crying:
I want to save the tablet if possible.
Hi, could you explain exactly what you've tried?
In particular what you mean by "I got to do the fastboot and flashed motorolas images but nothing." and "no matter how many time I flash new images it always stays on the original, so I can´t flash any special recoveries either"
By flashed Motorola's images do you mean you flashed the stock images?
And when you say you flash new images but it always stays on the original, I assume you mean the recovery stays as Xoom default?
Let me know and I'll see if I can help.

Yes I mean stock images, and yes, it always stays on Xoom default, it never changes no matter which Recovery image I flash.
The recovery is likely reverting to default because the Xoom does this automatically each boot.
We might be able to give you a recovery that stays put but the booting issue may or may not be something worse.
Being able to fix the recovery in place is reliant on adb working from recovery itself, which I'm unsure is possible.
Whilst you seem to have reasonable knowledge of flashing and using adb/fastbbot, I'll give full instructions.
I assume you have the necessary files for fastboot so I'll skip that.
Place your chosen recovery image in your fastboot folder. (I recommend ClockworkMod Touch recovery from here)
Hold shift and right click the folder containing your recovery image and fastboot files, then select 'open command prompt here'
Your PC is now setup for the fastboot process.
Connect your Xoom to your PC.
Power on your Xoom and once you see the Motorola logo, wait about 3 seconds, and press volume down.
The screen should show the Motorola logo in the center and '--> Android Recovery' in the top left.
Press volume down twice more until the top left says fastboot then press volume up.
The screen will say 'Starting Fastboot protocol support'
Now on your PC, in command prompt run the following:
fastboot flash recovery xxxx.img
Rename xxxx.img to whatever your recovery .img file is named​Once verified, reboot by holding Volume up and Power. (Keep connected to PC and keep command prompt open)
Again, when you see the Motorola logo wait about 3 seconds and hit volume down. You should see 'Android Recovery' in the top left corner, now press volume up to enter recovery, you should now see your flashed recovery.
This is where I'm unsure. Try running the following:
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old​If you are able to run this, this will rename the files that are reverting the recovery to default and prevent it happening again. If not, we can go ahead with attempting to flash stock images anyway.
To flash stock images download Build H.6.2-24 for Retail Europe (found here.)
Extract the files to your fastboot folder.
Again, reboot your Xoom, either by holding volume up and power, or from recovery.
And again, after about 3 seconds press volume down 3 times until the top left says '--> Fastboot' then press volume up.
Now run the following from command prompt:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock​This will wipe all data on the Xoom, and hopefully reset it to stock.
Finally, run:
fastboot reboot​and you should boot into Android 3.2(?), fingers crossed.
If you require further clarification or help let me know.

Thanks for the info, sadly I have done almost all that, I can´t use adb commands because I never allowed the tablet to do USB Debbuging, since I wasn´t doing anything that needed that and never thought I would need it. I think I didn´t kept the tablet connected to the PC, so I will try again and let you know if it works.
Like I said before, I'm unsure whether it'll work as I'm not an expert.
However, you may find this helps:
Whilst in recovery and connected to your PC, open Device Manager, find your Xoom, usually under 'Other devices'.
Then right click on your Xoom > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer > Pick your Xoom (either one if there's two shown)
Windows should confirm the driver installed then adb should work in recovery.
I believe ClockworkMod Recovery enables USB debugging anyway, through modifying default.prop
I'd recommend trying the above, and/or if that fails for any reason download Motorola USB Drivers here.
Thanks again but nothing works, I tried rebooting being connected to the PC and the same thing happens, the default recovery from the Xoom stays there, fastboot shows on the command Prompt and in the tablet that everything went ok and the new image was flashed but the rebooting kills it, and I can´t use any ADB commands because of the stupid USB Debugging, if something like this can happen, Motorola should have left it open from default or at least have a fail safe in case something like this could happen. RDS also flashes an image but when it rebbots the whole thing goes to hell, it stays on the damn logo with the same images. I think I can throw the tablet to the trash :crying:
Unless its a serious hardware issue, I wouldn't trash it! It clearly has life as you're able to successfully flash and such.
I'd recommend having a look at the FAQ.

Thanks, but I have done everything, what is the good thing of a successful flash when the tablet returns to it´s previous state as soon as it reboots?
Plus I can´t use one of the most important things, adb, because of the usb debugging, I can´t get into the tablet to activated it, and even if there are recoveries which bypass this thing, I can´t flash them into the tablet, well I can, they just aren´t there after the reboot. And all this because the tablet run out of battery :crying:
ClockworkMod recovery itself allows the use of adb regardless of USB debugging setting.
I believe the command adb remount should allow it.
If adb is denied you can try what I said earlier

The problem lies with the recovery, I only have the default recovery from the xoom, it doesn´t matter how many times I flash it and everything seems to work correctly, when I restart the tablet I get the default recovery. I don´t understand why this happens, command prompt and the tablet in fastboot mode tell me the recovery has been flashed, but to use it I have to reboot and when I do I always find the same good for nothing recovery.
recovery
Hello,
I don't really understand your problem with the recovery ?
When you flash a custom recovery with fast boot, you restart the tab and after 2 or 3 second you see the Motorola Logo you push the volume down
and volume up button to enter in the new recovery.
If you flash custom recovery but restart completely the TAB without manually enter in the custom recovery, each time you retrieve the original recovery.

Here is what happens, I flash new recovery, I restart the xoom with power and volume up, when the logo appears, after 3 seconds, I push volume down, recovery option shows, I press volume up and the default recovery is still there, not the new one I just flashed.
Is really no one out there that can help? :crying:
There's nowhere stated that, however I believe you already have unlocked your bootloader, didn't you? Because it's REALLY weird that it can't flash the recovery, I mean, you left the battery run out, then after charging you wasn't able to boot normally again.
I'll think a little, but give a check if your bootloader is really unlocked, the device should have installed the recovery, and as you didn't restart it entirely (let it go after the dual core logo), the recovery should be there...

I have done the fastboot oem unlock command, should I do it everytime? I can´t use adb, because like I said, I never check the USB Debugging, which I have done in my other tablet now, don´t want the same thing to happen twice.
is it dead?

[Q] Stuck at Boot/Starting Apps

Hey folks!
Again a problem with my little phone.
Today I got similar reboots, after about 5 it got stuck at the bootscreen.
Tried to wipe cache+dalvik, booting it up again, but after it prepared all apps it stucks at the "Starting Apps" window..
Also flashed another kernel and recovery. Nothing worked so far..
Any help, because I don't want to wipe data because I made some important photos today and I don't wanna miss then..
Thanks in advance,
RS

First of all you connect your phone to PC and try to copy all the content of /sdcard to your PC. If it doesn't work reboot your phone to fastboot and connect it to your PC with CMD (in fastboot folder) running and enter the command "adb pull /sdcard C:/" without quotes, Also you can replace C:/ to any address where you would like to copy all your SD data.
After that you can flash any ROM to get your device in working condition.
If you have any query do ask or you may end up losing all your data.

Why don't you try the fastboot method.
Put your phone into Fastboot by pressing volume down+power button. Connect it to your PC, fastboot would recognize it for sure. You then enter the command. You can even use adb from fastboot.

It just says "device not found" when using adb.
with fastboot I can flash things but can't pull or?

Is your boot loader unlocked, if not you'll have to unlock it first (but doing so will void your warranty).
Assuming that you have a unlocked device follow the steps below to get all your data. (I myself tried and it worked, so it must work on your device also)
1. Make sure you have installed drivers for your Moto G, if not then do it.
2. Download the adb file to access your phone during fast boot.
3. Download the TWRP recovery 2.7.0.0 by dhacker for falcon (Moto G) on your PC and copy it in the adb folder.
4. Rename the downloaded file to "recovery.img" without quotes.
5. Connect you phone in fastboot mode to your PC and flash the recovery by command "fastboot flash recovery recovery. img" without quotes.
7. On your phone then go to recovery option and press volume up key until phone vibrates. The phone will then go to recovery mode.
8. On your PC, in command prompt(adb) enter command "adb pull /data/media/0/ C:\Moto" without quotes. The process will start and may take hours depending on no's of file and their size.
P.S. I won't be able to answer any more of your question as I won't have data connection any more. I'm sure if you will follow all the steps properly, you will get all your data. If you can't understand anything then just Google it.
Phone doesn't proceed from boot animation!
Guys!
This would be my 1st time here. I've never faced any sort of problem with any of my android devices but this one.
My phone got lost a week back. So, I used "android device manager" to wipe/lock the phone but I think it didn't as the phone was switched off all this while.
So, some gentleman found my phone and returned it to me just today. I put it up for charging. It popped up 0% battery screen and turned on after 10-15min.
As soon as the boot animation(earth/buildings) finished it jumped to a black screen.
It has been on charging for last 3 hours.
So my questions are
1) Can I make back up of the data without turning it on/formatting it?
2) How can I make it to work?
Thanks a lot in advance!

@vjsharma89 :I have posted the answer in your thread.
And after you had backuped your data, factory reset your phone from fastboot by choosing factory option and then reboot it. Or should work fine.
delete this pls, wrong thread
