[Q] Help me Please (No command error and boot loop) - Nexus 7 (2013) Q&A

hello everyone I know this is not the Ideal place to ask but I do have some serious issue with chain fire. I am completely new to this area of computing and this situation is sending me crazy. I rooted my nexus 7 (2012 edition) ages ago and recently I did something stupid. This is what happened
one day I tried to play the android game NOVA 3 on my Nexus 7 on the highest graphical setting so I went and researched how to do this. I was pointed towards some kind of app called 'ChainFire 3D', Once I pressed the install button inside this app the Nexus 7 switched off and the next time I tried to turn it on I got the X logo of death (boot loop). I then tried to enter recovery and I got the annoying 'no command' errorhttp://forum.xda-developers.com/images/smilies/crying.gif. I cant seem to remember how I rooted this thing but I do have access to the fastboot stuff ONLY (inside cmd).
if there is anyone who has any idea how to go about fixing such an issue without wiping everything on my nexus could they please get back to me ASAP.http://forum.xda-developers.com/images/smilies/fingers-crossed.gif

This forum is for the 2013 version, but the answer will be the same, flash the stock image. I have the link in my signature.

Can I have some instructions
http://forum.xda-developers.com/images/smilies/confused.gif what do you mean by flashing the stock image. does this mean connecting it to my computer and running cmd and using some kind of fast boot command or something?. Also will all my data still be there such as my apps, etc after the flashing is done.? http://forum.xda-developers.com/images/smilies/eek.gif

[Q] Screen flickering / Bootloop -> Is my Nexus dead? Data recovery possible?

Hello,
just some hours ago my Galaxy Nexus (SC-04D) rebooted while lying on the table next to me. After several sings of vibration I noticed that the phone doesn't boot completely.
When switching on the phone I get the turn-on-vibration, then the google letters are displayed. Most times the word "google" flickers from left to right over the screen (only the line where the word is supposed to be). Sometimes it boots further and I get the colored "X" displayed. This symbol starts flickering, too and if it went so far it reboots.
Here are two pictures I took from the phone failing to boot:
picpaste.com/img_0001_01-Rmm7kDYb.jpg
picpaste.com/img_0001-eoLqVoiM.jpg
The phone is running stock Android from Docomo. The phone is about 14 months old and has never been unlocked, rooted, modded, taken a bath, ... 'til now.
I tried starting with and without SIM-card, with and without charger attached and let it lie around for several minutes without battery between my tries.
Is there any chance to get my data from the phone or even get it fixed? Please give me a hint what I can do.
Well the Red exclamation mark means that there is a problem with the phone reading the build path. Since you have never rooted the phone, this would mean that the files got corrupt on the phone. With a non-rooted phone a Factory Reset is about the only solution, but is probably only a temporary fix. This is most likely caused by too many apps on the phone and it just freaked out on something eventually.
I think these options might work for you, however I cannot confirm since I have rooted my phone from day one and never looked back:
Power button + up volume= recovery
Thanks GPFboy for your fast response,

As far as I understand a factory reset results in a complete loss of data on the phone, right? So without root/unlock there's no chance to get my data from the phone? That would be really bad.

What is "too many"? I think there are about 35 apps installed atm. By the moment the problem arose wifi and 3g-data,BT,GPS were disabled and just a minute before I took a look how late it was. So nothing special.

The phone reaches fastboot mode, but when selecting recovery mode I get the google logo and after that the open android with the red exclamation mark. That doesn't look good, does it?

It's still locked.
you might try and go into recovery,
then press (i think) power and vol up and try and see if you can wipe just cache.

ok, I tried that several time now, but it didn't work. The only thing when I select recovery and press the power button is that I get the google logo and then the dead android + red exclamation sign, but this screen is scrambled and shows flickering pixels as shown in one of my pictures in the first post. So recovery mode seems not to work for me?
Is there a software or hardware problem with my device?

You can try to unlock your boorloader and flash a custom recovery like cwm or twrp. Maybe that helps. You can always go back and re lock it.

He wants to keep his data... which, at this point, seems rather impossible.
If fastboot doesn't solve it, i would try omapflash, OP. That "flickering" doesn't look good.

Yes exactly this is the point. Since I don't have a current data backup the first thing to try is getting my data from the phone. I already tried temporary loading the clockwork recovery through fastboot - with the galaxy nexus toolkit and by hand(sdk) - but it failed ("Bootloader locked").
What I'm wondering about is the fact that the phone seems to behave normally in odin and fastbood mode but going nuts the moment it's expected to boot. Besides the flickering google logo and the "matrix-modded" dead android it even ended up in a totally green screen one time.
At the moment I don't dare trying to unlock/flash the phone because of being afraid getting stuck and ending up with the phone being in some kind of undefined / totally broken state. Initially I was in hope of being able to rescue my data but now i will try my luck with docomo support first.
As far as I understood omapflash is primary used for recovering bricked phones not even starting to odin/fastboot mode. But thanks to your hint I found http://forum.xda-developers.com/showthread.php?t=2016628 "Unlock bootloader on GT-I9250 without wipe and without root" This might bring some chance for data access.
I will try to get through 1 to 4 of the guide first and see how far I get.
If this won't work I might try to unlock, recover and try to "undelete" what's possible. (http://forum.xda-developers.com/showthread.php?t=1994705)
Does this order make sense?
Btw, having a dead phone is bad, of course, even when I got it new for 2300Yen but loosing some pictures i really liked and having no phone atm currently hurts more. Especially when knowing that I was thinking of copying all photos to my computer only one day before when I pulled only some minor important ones from the phone I needed for work and planned to do a full backup and unlock this weekend when I get back my 'Milestone' currently lent to someone else.
Once again something I learned. Backup! Even you phone.

It will work actually, I read/also replied to that thread! I had forgotten about it, sorry. I must say that if you had already read the stickies that matter, you'd already know about it.
It will unlock your bootloader, bypassing fastboot. Still, it's not for the faint hearted. I refered to omapflash because its a low level tool, it doesn't require the bootloader to be unlocked, and is able to restore the bootloader to working state, and I got there because you mentioned you see graphical glitches/flickering which may indicate bootloader partition failure and/or consequent corruption.
I think that's your best shot at trying to get your data back. After unlock, boot to fastboot and 'fastboot boot custom_recovery.img', and grab your stuff (if you can) from /data/.

Your hint was very helpful for me getting the right direction since I'm just starting to dig into all this stuff.
Unlocking went quite well. Writing back to the phone worked without a problem and after that it's shown as unlocked in fastboot mode.
It even started loading clockwork recovery with fastboot. But the initial cw recovery screen (their logo and the cw recovery footer) was already shown on a scattered screen (google logo + unlocked lock was fine). After that the usb port connected and disconnected several times, then the screen went blank.
May this be because of corrupted fs or defective hw?
From my understanding with omapflash one have raw access to the phones internal memory similar to with dd on Unix/Linux. So currently I'm trying to dump ("upload") the emmc from the phone - actually in smaller chunks since omapflash needs to allocate all the memory in advance for the upload and to prevent interruptions. This will take a while...
After that I want to try to 'cat' the parts together and mount the filesystem - might be possible to do this from linux since it seems to be ext4 filesystems

[Q] [Nexus 7 - 2013, wifi, 16G]Got stuck at Google logo

Hi everybody,
I'm so angry with my Nexus 7 (wifi 2013) because I just made it mess up.
Let me tell you how stupid I was.
First, I tried to root but it failed.
Second, I used 'Back to Stock' with 'Nexus Root Toolkit v1.7.2'. Finally, I got stuck at Google logo
I tried some solutions on the internet but it still unchanged anything.
Could you show me how to fix it, please?
Thank you so much.
This is the images of error that I got (I'm sorry I cannot insert image because I'm a new member of this forum, could you go to the link below to see more details?)

Hey namserious,
How did you get it working? Did you use the Mini guide given by sfhub? I'm having the same issues with my nexus 7 (2013). I only used for one day. Restarted on the second day and never got anything after the Google logo. Also, my phone wasn't rooted, so I didn't have developer options turned on and since I can't get into the system, I can't turn it on either. Will that make a difference?
Thanks.

If you didn't root the device or do anything else with it, you should be able to get into Recovery Mode and do a factory reset.
https://support.google.com/nexus/answer/2668187?hl=en
Even recovery doesn't work
I'm not able to get into recovery mode. When I select recovery mode, the tablet starts and displays Google logo again and gets stuck there again.

When you get into recovery you will see just the droid and the red triangle. At this screen you will need to push the power button then Vol Up and release. I had to do that about 3 times then I was able to get the menu items. From there I did a factory reset. After that I was good to go. Hope this helps!

Im sorry, I didnt read correctly. I had issues too restoring back to Stock since my setup was all changed. I had to use these steps. I am going to assume you know how to use fastboot and what it is.
DISCALAIMER! These steps will delete your user data!!!!
> fastboot erase boot
> fastboot erase cache
> fastboot erase recovery
> fastboot erase system
> fastboot erase userdata
> fastboot flash bootloader BOOTLOADER.img
> fastboot reboot-bootloader
> fastboot -w update IMAGE.zip
So after that I was able to get past the google logo but just stuck at the boot logo (Multi Colored X) I then had to get into recovery using the steps I stated above then did a factory reset.
Success
Rb, I just tried your instructions. YOU ARE A SAVIOUR :laugh:. After 2 days of continous troubleshooting, I had given up my hopes and was thinking of returning it. But suddenly after getting used to seeing the Google logo, I just noticed the android robot on the screen. And after a few seconds I saw the welcome screen... Viola.
Thanks man, I really appreciate your help. :good:

Glad to help! The best thing about Nexus devices are the different fail-safes. If the Rom is screwed up you can flash a new one from recovery. If recovery is screwed you flash a new one from the boot loader. If the boot loader is screwed you can flash another from recovery. Also the N7 2013 tablet is the best for the money. I user mine for work. I am a tech admin for a school district and have certain tools located on my desktop (Active Directory, Printer Manager, etc) and I have RDP installed on my N7. Now when I need to reset a password or whatever i can just RDP to my desktop. This tablet has made my life easier and hopefully yours will too now.

This is my first experience with a Nexus device and I might have judged it in a wrong way. But I think the problem is not the device but the information regarding the latest Nexus devices. Hopefully there will be more workarounds of the new Nexus devices.

Hey, know it's been a little bit but my nexus 7 says no OS in TWRP recovery. I tried flashing it back to stock but it doesn't work. The bootloader is locked and when I try to do anything manually it just hangs on stuff like erasing 'system'/cache etc... in fastboot. I have not been able to find anything to work. And when I try to fastboot oem unlock it gets stuck when i press volume up and power to accept unlocking it. I have tried different cables and another computer. maybe I should try a third computer.. Do you have any suggestions?

I know this is an old thread, but I'm having this exact issue. I'm just stuck on the google screen. I can get into the bootloader just fine, but not the recovery. I followed these directions. Flashed the factory image and everything. But I still can't get past the google logo. I've followed every bit of advice I could find on this issue and I can't seem to get it working. Any help would be greatly appreciated!

Does anyone know what's going on? I've tried everything I could find. Multiple times. From the suggestions listed here to the WUG kit to this http://forum.xda-developers.com/showthread.php?t=2381582
Nothing is working. I goes through the reflashing successfully. The command prompt says that everything is done. And then it just gets stuck at the Google screen again. I'm at my wits end and have no idea what to try next. I know that because I can get into the bootloader still, there has to be SOMETHING that will work. But I just don't know. Any ideas?
is there a android L Developers Preview flashable zip? thanks

Anyone figure out what is causing this? I got a remanufactured 2nd Gen N7 16G yesterday. Updated to 4.4.4 over the air. Then unlocked the bootloader and rooted. Everything went fine. I installed Franco's latest kernel (r17) over stock and all was well. However, this morning, while using the device in the middle of GoW, it rebooted to the Google Screen and froze there. I could boot into the bootloader and have my comp recognize the device, so could ADB and Fastboot, however, I could not get into recovery. (I had installed TWRP 2.7.1.1 when I rooted). Trying to get into recovery would just freeze at the Google Screen.
So, I then tried both manually ADB'ing commands, as well as using Wug's Toolkit, and both methods seemed to complete successfully without error (I was using the latest Razor-Flo 4.4.4 files from Google's Dev Page so it is not an issue where I am using the Gen 1 files for Grouper or anything like that in error), however, neither method allowed me to boot into recovery, and left me at the same place. No matter what I did, I was stuck at that screen. I ended up calling Asus to RMA.
So, while it is not a current issue for me, I am interested to know if anyone has sorted what the root cause is, and whether it is an issue on the hardware side. I am not a complete noob to the N7 (I have 2 Groupers), and have been modding for a few years on Samsungs, and until this morning, have never had a soft brick I could not fix. This time, I gave up.
Same problem here, I have a Deb 32g, it went a little wonky and then rebooted. No amount of flashing and wiping and fastbooting has been able to recovery it. Gets stuck on Google Logo no matter what I do. Can't get recovery. Can't boot past Google. It will do fastboot without errors, but that's the only thing it will do.

[Q] Nexuz 7 stuck at the google logo

Hello I need a but of help my Nexus 7 is showing my nothing but the google logo and at the store earlier it showed the android with his chest up and a red triangle. it doesnt even show the moving colors after i turn it on it just sits and says google like a paper weight. i can turn it off and on but nothing more. the geek squad at best buy told me to ask for help here at Xda. last thing i was doing with it was opening deer hunter 2013 and next i go to see if it opened and it stuck on the google logo. can anyone help me fix my tablet? its not under store warranty only manufactures.
Well, sucks to be you.....just kidding...but that does suck. Now, on to more serious matters...
Do you have access to your bootloader? (hold the power button + the vol up button at the same time) If you do, you might want to look into rooting the tablet. Based on the content of your post, I am assuming that you haven't. There is plenty information about rooting the Nexus 7.2 tablet (and just about every other Android device). Simply Google "root Nexus 7 2013" and you will quickly find your answer.
Also, how much do you know about rooting and the sort? I want to know before I waste my time giving details about info that you are aware of.

i dont know anything about rooting. i dont have access to the boot loader. i did a few days ago now it wont even show up, the guy and best buy tried to bring it up and its like it was showing a dead android or something chest open with a red triangle above it. he said someting about maybe have to flash a new or or something like that on to it, it wont show me anything just stays off or shows the google logo when its on
Sigh...that is the bootloader. Maybe...he could have booted into the stock recovery, which shows this or something similar for most devices. Please remember, they are reps...they may know about the software, but usually they speak from their experience or their perspective. I'm glad that he sent you here for a second opinion.
Hold the volume down button and power button to get into the bootloader. You should see some options at the top of the screen saying Start, Restart bootloader, Recovery Mode, Power Off. Not sure if those are the exact options, but it's pretty close.
Also, you need to look into rooting your device. You need to download some files first. You'll need adb, fastboot, and drivers for your Nexus.
And one last thing....what Computer OS do you use? The rooting process is slightly different for each one (Windows 7, 8/8.1, Mac OS, & Linux). If you are into computers, and you have Linux installed on a device, good for you. That is my preference when rooting, as Android is built from Linux, and naturally supported without the need for drivers.
I had similar problems when I first bought it. Going into recovery and resetting the tablet cured it. You will lost all your data BTW.
He's facing the loss of his entire tablet, so I'm sure that data loss isn't the biggest thing to worry about.
But yes, just about every solution involves a clean wipe of data.

I'm stuck on the google logo too. I had my tablet plugged in over night and when I opened the cover this morning it woke up, but as soon I tried to access anything it rebooted and stuck.
I'm unlocked and have tried various thing. NRT doesn't recognize it as an ADB device so I don't think that will work. Fastboot works, but I keep getting "FAILED (remote: flash write failure)" when I try to use the factory flash all, or the instructions found here: http://forum.xda-developers.com/showthread.php?t=2381582
I can use fastboot to query the device and get it to return "flo" but it seems like the flash storage has failed.
if it's truly horked, can I use "fastboot oem lock" to relock it and attempt a warranty replacement?

You can try Method 2 from this post: http://forum.xda-developers.com/showthread.php?t=2513701
I know it's for the N5, but I used this one for both my Galaxy Nexus, N5 and N7. Since they are all Nexuses (Nexi?), the same general procedures apply. I always prefer to do it all manually, step-by-step, which is why I went with Method 2 in the OP of that thread. Obviously, since this is the N7, just skip the radio flashing command. Everything else is the pretty much exactly the same. If this doesn't work in fastboot, then it's probably a hardware failure.

[Q] Nexus 7 suddenly bricked ?

Hello all, so yesterday I went on my tablet (Nexus 7 2013 WIFI ver.) and browsed the net a bit and went to sleep. I recall having around 30% battery power. This morning I wake up to an apparently flat battery (power button didn't turn on anything) so I just plugged it in and did something else. After a while, I took my tablet and started it with the power button. However, it got stuck on the Google logo and never fired up anything. I've rooted the tablet quite some time ago (months) so the cause is not from there.
Things I haven't recently done:
Installing an app.
Rooting or flashing anything.
Updating an app.
Things I have tried doing to fix the problem:
Booting into FASTBOOT then trying the recovery mode = still stuck on the Google logo.
Booting a custom recovery image using Wug's toolkit = frozen at the team logo (TWRP) / black screen (CWM).
Flash Stock + Unroot (Soft-Bricked/Bootloop) = FAILED (flash write failure).
So now I'm really stuck and desperate to make the device work again. I've been reading all day long and trying all sorts of solutions to no avail. And it seems far-fetched to me for a device like this to just instantly brick itself without any reason at all.
Can anyone help me with this case ? Or does anyone has any idea what just happened to my tablet ? :crying:
EDIT: I'm afraid that warranty might not work as the device was unlocked and rooted so it's the last solution for me.
Bumpity bump
No one has any idea what happened to the tablet and how to fix it ? I've tried doing some more flashing but to no avail. It just refuses to flash and keeps failing to write the files.
I think you need to leave out on the charger for 1/2hr without doing anything with it. You are probably using what little power it has charged by trying to reboot it, etc.
I had to do that once and it did the trick.

There is no reason you should not be able to get in to recovery (power and volume down).
You could call Motorola. They have good tech support.
The exact same thing happened to me. I rooted it months ago and haven't changed a thing since then. It just froze up a few days ago. I restarted and it just gets stuck on the google screen. I can get into the bootloader, but when I try to go to recovery, the google screen comes up and won't go away. I've tried every method I can find for flashing the stock image and absolutely nothing is working. I just get stuck on the google screen.
Please update this if you find a solution!
Do u guys have the most up to date version of whatever particular recovery that you're on?
Yep. I've flashed the stock recovery multiple times to no avail. :/

If you can't get into recovery or flash any images it sounds to me like a hardware failure. Bad memory maybe? If you've tried everything then RMA to Asus before the one year warranty runs out.
Have you tried to see if your computer sees your N7 by typing fastboot devices if you have the sdk installed?

I was to slow with my update. Does your computer see your N7 with fastboot?

Yes, I can get into the bootloader just fine and I can use fastboot. I go through the flashing process and the command prompt says everything flashed successfully, but when I restart the device, it hangs on the google logo. The same thing happens when I try to boot into recovery.

If you fastboot flashed the factory image and can't boot up then it sounds like a hardware problem. Out of ideas, sorry.

I'm not sure what happened, but I just ran this little utility again (I've done it many times over the last week or so to no avail) and it actually worked. Hopefully it keeps working!
Thanks for your help!

Any of them will do, the latest is preferred.

I have the same issue. I flashed the stock rom like 4 times without success. I've read almost every troubleshooting guide here and google forums. I don't know what to do. I can't even access to the recovery.

I got a security update and that's when the phone went kaput.
Did you flash the same stock ROM 4 times or did you try different ones?
By the way, I have the Nexus 5 and had the same issue I'm having now, so this will be my last LG phone and maybe my last Nexus.

I tried 3. The oldest the newest and one of the middle. I flashed them with the Nexus root toolkit and with the command prompt. I really don't know what is the problem.
Did you fix your Nexus 5? Because I read that could be a issue with the power botton. I am wondering if the N5x has the same issue?
Looks like this is a common issue at the moment.
I'm in the same boat. I can get to the bootloader screen, no issue. But if I try going into recovery mode, or standard boot. It just loops on the google logo (or sometimes just sits there at the logo for an hour).

I posted the issue on LG USA Mobile Facebook page. I received a message: "In order for us to address your concerns, we ask that you please send us a private message. Thank you for reaching out to us. "
I suggest anyone with the same issue do the same. That way people are aware of this issue. If I knew before hand I would not have got the Nexus 5X.

I was able to get the Nexus 5x working again.
I downloaded the ROM that matched this line from the Android Recovery screen.
6.0.1/MTC19Z/2996059
I first downloaded and installed the ADB USB drivers adb-setup-1.4.3 as administrator, saying yes Y to all prompts.
I created the folder C:\nexus and placed the ROM on that folder.
On the Nexus 5X Android Recovery screen I selected “Apply Update from ADB” .
At this point I attached a USB cord between PC and phone.
At the Command Prompt I entered: adb sideload c:\nexus\bullhead-ota-mtc19z-b4cfce2c.zip (here replaced the section in bold with the name of your ROM).
When the update finished I selected the line “Reboot system now".
Voila! Phone is back to life.

"Okay Google",
Being a admirer of google i went into buying Nexus 5X as my smartphone. As this model was relatively costly i had many objections from friends and family. Still i insisted for the same "LG Google Nexus 5X".
Previously i had heating issues with the new phone. but the service centre guy said it will heat "abit"(i know that was not bit) as it is a smartphone.I had to keep the new phone in charging for hours and that two three times a day.
Against all the odds i was in favour of google as it sounded good to tell people which phone i had, But the people who saw me always looking for charging plug knew what i was going through.
Currently i am facing the reboot loop issue, my phone keeps on rebooting. I went to the one where i bought the phone.The guy said it requires a software update and nothing else. I had heard of the peoples having such issues worldwide and i was worried about the solution. So i had sent my phone to the LG's Service Centre their the person said if only software update is required then it will cost around 350 INR else we will let you know. So after a long wait and contacting the service centre their i finally had a talk with them and they said it seem to be a PCB problem and costsaroung 11000 INR. Hearing the figure was a shock!
I don't know what to do with the situation as my phone doesn't have the warranty. Please help me as this is a HUGE amount to spent to repair a phone.
