I searched the forums and don't know what to do. I installed cwm through ROM manager. I was able to boot into cwm from ROM manager. I did a nandroid backup. I tried installing aokp build 4 but got an error (don't remember what it said now). When I tried to reboot it stays stuck on the Google screen. I don't know how to get back into recovery. I've tried rebooting by holding down power and the volume up and down buttons. It just goes back to the google screen. What can I do?
When you're at the bootloader, in fastboot mode, connect your n7 to the PC and execute in the command line
fastboot boot nameofyourrecovery.img
Or just use the toolkit in the sticky at dev section.

Hi,
I had the same issue on Friday. Started after i reflashed the recovery via Rom Manager,
I fixed it by doing the following.
Download and install this toolkit. http://forum.xda-developers.com/showthread.php?t=1809195
I managed to get the device into bootloader mode by holding the Power + Volume up and down for around 20 seconds.
Flash the Google Factory image. For me this was the only way to recover it fully. tried various other things first.
After that completes you can go through the full root and flash procedure again. The toolkit makes it all so very easy. Thanks to the developer for that.
Thanks

I had a similar issue after using the Nexus Root Toolkit to flash to nakasi 4.2 with CWM recovery - just got stuck on the nexus boot screen, flashing in a loop for over 15 minutes.
I ended up powering down the device, holding power for about 5-10 seconds - then QUICKLY holding both the power and volume up+down keys, it then went into the fastboot screen.
After it was there, plugged it into my PC.
Now, this should work for you - assuming you have all the fastboot/usb driver stuff installed.
I extracted the contents of nakasi-jop40c-factory-6aabb391.tgz into the same directory as the fastboot.exe provided by WugFresh with his Nexus Root Toolkit (google search or xda search for this if you dont have it, i dont think i can post links due to my low postcount) - typical filepath: C:\Program Files (x86)\WugFresh Development\data
By the files in there, I mean drilling down inside the tgz to where the image files were inside so that files like bootloader-grouper-4.13.img, image-nakasi-jop40c.zip etc were extracted into the directory and sitting alongside the fastboot.exe - NOT in a subfolder.
Once its all here, running flash-all.bat (this is provided by google in the nakasi-jop40c-factory-6aabb391.tgz) from the command line or by double clicking on it from explorer should kick off the process. After about 2-3 minutes, it was complete, and my Nexus then booted up within about 3 minutes after that.
Also worth noting, device remained unlocked, but I lost root/root binary

Hi
I just rooted my nexus 4 using the superboot. And made backup using titanium. But the problem is i tried using
androidrootz.com/2012/11/how-to-root-nexus-4-on-mac.html
earlier to try to root the phone and after unlocking the bootloader and wiping the device i couldnt get into the recovery mode. Now it comes up with android lying down with a red triangle over this. The phone switches on fine.
I am rooted though. Just need to get into recovery mode. Any help, please?
I had this happen to me. I imagine you used CWM to flash Superuser right? When you rebooted through CWM it said something about do you want to disable recovery from being reinstalled to stock, something to that extend.
Basically I think what you have to do is reflash your recovery. Either stock or a custom recovery (cwm etc).
In fastboot you would do fastboot flash recovery recovery.img (recovery.img being CWM)
Hey thanks for the quick reply.
Well I am fairly new to android. This being my first Android handset. Can you please tell where to start with. Though i remember this fastboot command i entered earlier. Did i mention I have SU on my handset now.
And is there any other way to get custom roms other than CWM? If i got for stock recovery do i still retain root access? and how can i can flash stock recovery if possible.
Really appreciate this.

No problem at all. I suggest reading this thread: http://forum.xda-developers.com/showthread.php?t=2010312
But I will highlight what you need to do:
C. Download the required files to your computer and extract them
1) All of the files that are required, need to be in one (i.e., the same) directory. It does not matter what it is called, but all the files need to be in there, with NO subfolders. EVERYTHING needs to be extracted into this one directory;
2) Download the attachment from the end of this post and extract the contents to the directory created in step 1. Note: if all you want to do is unlock your bootloader, skip to step 7 in this section (C).
3) Download the version of Android you want from https://developers.google.com/android/nexus/images#occamjop40d. Make sure you are using an occam image which is for the Nexus 4. Most old versions are not usually available on that site; however, there is a mirror on this site: Random Phantasmagoria.
4) Download the appropriate version (for your computer) of 7-zip from here and install it.
5) Extract the files from within the .tgz file which you downloaded in step 3 using 7-zip, not WinZip or WinRAR or whatever.
6) Make sure you have extracted ALL the files (including extracting any files in any archives inside the .tgz file). You should have six (6) files ending with .img in the directory you created in step 1. The other files you extracted from the .tgz are not necessary;
7) Reboot your device into bootloader mode (by turning it off, hold volume down, and press and hold power) and plug it into your computer;
8) Open a command prompt in the same directory (i.e., make sure you are in the same directory as your files are located). You can hold the shift key when you are in the folder in Windows explorer and right-click in a blank spot and it will open a command prompt.
then: 12) Optional (NOT optional for n00bs) -- Flash the recovery partition: fastboot flash recovery recovery.img (this should be inside the occam-jop40d-factory-ca7602f0.tgz )
Now hope this all works for you, I am at work and have never actually done any of this on my own (other then flash a custom recovery).
But that guide is awesome, read through it sure it will help you out.

Yes is supposed to get there the problem is, I get to the first menu, press volume down to select recovery mode, get in to recovery mode, it gets in and shows a laid down android with the red triangle on top an the no command message below, I press volume up or volume down and it does nothing just keeps showing no command, the only way to get out is by holding power button for several seconds.
this never happened to me on mi Galaxy and I don,t know whats going on, as I said on this particular device I haven't rooted or unlock the boot loader, it is completely stock.
Thanks in advance for your help.
To get to the menu on the triangle thing, you need to press power then while holding it tap the volume up. After that the menu will be shown. Pressing only the volume buttons won't do it

As i said before, I press volume down + power and get to the main menu, then i select recovery mode by pressing the power button and enter recovery mode (all this works perfect), after I enter recovery mode, there is just the android with the red triangle on top and the no command on the bottom, and I press the volume up and down buttons and nothing happens.
As I said this is a new device never rotted locked boot loader, I really don't know whats wrong here.
You're not reading it correctly. When you are in the android with triangle, press POWER then VOLUME UP to access the menu. That's what I've been saying two posts up. Pressing just the volume buttons in that screen won't get you anywhere

happened to me, too. easy solution, get goomanager from play, tap settings, tap install open recovery. that will install TWRP right away. btw, TWRP is everything that CWM is not, use it, its so much better.

Man, Thanks, now i got it, it worked perfectly. you guys are the reason I am on android and not in another OS. Thanks again
So, I followed this guide: http://www.androidrootz.com/2012/11/how-to-root-nexus-4-on-mac.html
Booted in CWM followed all the steps, and the last step to reboot the device, it rebooted but never went back to CWM.
Now I am constantly getting the Android with Triangle and "no command" so I guess it keeps me in stock recovery.
My bootloader shows unlocked.
Please help, what should I do? I can't seem to get the phone to do a hard reset by holding power+volume down then tapping back and home?
When you get to the android with "!", it should be power then volume up not volume down

go into the bootloader/fastboot and try booring from there. you also might need to wipe data/factory reset then reflash your rom. also, sometimes force rebooting from a bootloop will boot it(long press the power button while in the bootloop, hold the power button for 10-20 seconds).
I had this happen to me yesterday when trying to flash a custom kernel to use with CM 10.1. The way I was able to fix it, was to pull the boot.img from the ROM zip and flash it through fastboot in the bootloader. The short and simple way is this:
Open the command prompt or terminal in the folder where fastboot is on your computer, extract the boot.img from the zip file of the ROM your using and place it in the folder with fastboot, then on your Nexus 7, hold in power + volume up + volume down to turn it off. Then hold down volume down and press power to boot into the bootloader. Once there, type in the command prompt/terminal: fastboot flash boot boot.img then reboot and you should be good to go.
Can I just remove the ROM?

So if I back up the devices files with CWM and factory reseting it will remove the backup, so is there a way to send the backup onto my laptop?
Also is it possible to just remove the rom because I feel like my life would be easier if I unintalled it.
Thank You!
Hmmmmmm

How do I flash 4.13 bootloader?
All you have to do is download the same ROM on your computer that you have on your phone. If its stock 4.2.1, then download the factory image of it and extract the boot image from the zip file and follow the same steps I outlined, though instead of using: fastboot flash boot boot.img, it would be fast boot flash boot <name of boot image>.img
If you still have trouble, feel free to message me here or on GTalk and I'll walk you through it.

There's an important lesson to be learned here, and you unfortunately learned it the hard way. Never, ever, blindly flash something. You need to read the OP as well as catch up on at least the last page or two of the thread. Had you done so, you would have noted that Clemsyn's Elite kernels are not compatible with 4.2.1.
I'm not saying this to be a condescending, but rather to save you the possibility of getting into situations like this again. Fortunately, Nexus devices are easily recoverable from various user errors.
Hello,
I saw that the OTA update to Lollipop was available on my phone today, so I went ahead and let it download. Upon completion of the download, it restarted and applied patches, then restarted again and has been stuck in boot loop for about an hour. After reading several other threads on how to try to reset the phone, I'm stuck. When I try power + volume up or down, the LED status indicator flashes red and I never get to any kind of other screen. Am I completely screwed? I previously had stock 4.4.2 with no modifications.
Finally was able to get to the bootloader menu. Apparently having the phone plugged into the charger was preventing me from getting there for some reason. I ended up having to wipe the phone to get it to boot
so you can get into clock recovery right? download nexus 4 toolkit..that might save your phone. I suggest you to unroot and flash everything to stock and then unlock again and start everything from scratch. good luck.
Similar issue on an OTA upgrade to an unrooted N4. It's stuck on the Lollipol boot screen with the rotating Circle thingies.
I can get to the Android System Recovery but there's no CWM or TWRP on my N4. I'm guessing a factory reset will fix it but is there a way to preserve my pics/files on the phone before doing so?

I guess TWRP Recovery has option to enable MTP and you can access the internal SD card by connecting mobile with computer using usb cable.

Flash TWRP Recovery using fastboot.
1. If you have otg y cable, connect it and use file manager to copy all the files.
2. OTG method is failed then select “Mount”, then select only “Data” and connect your Nexus 4 to your computer and Enable MTP in TWRP. now you can use adb pull and push commands.
I ended up going the factory reset route, which wasn't really a bad thing. My photos had been backed up in dropbox and the play store remembered all the apps and were able to reload them. The only things I really had to do was reload some music onto the phone and re-enter passwords for apps.
Same story here: sideloaded the OTA zip file, then had bootloop. Tried a few approaches, but none worked. In the end only wiping the data was the solution for me. Lost some userdata in a few important Apps...
I went through this yesterday. The only way to get it to boot is a Factory Reset from Recovery. It works like magic, but sucks you lose the data.
Got the OTA yesterday and also got a bootloop(stuck in boot screen animation). I couldnt afford losing my photos/videos as i had no backup , so i figured out a super easy to get it to boot without wiping data .
I was unrooted with stock recovery running stock 4.4.2, bootloader was unlocked. I flashed CWM recovery through fastboot and wiped chache+ Dalvik from there then simply rebooted the phone .
I had already tried wiping cache from the stock Android recovery,needless to say that didnt work for me.
If anyone else is having the same problem please try the method above and report back, cheers!
I post this on Google Product Forum 2 days ago. Hope it helps

(updated 29/11/2014)[not perfect but it is a SOLUTION]
The idea of this is to downgrade your nexus 4 without wiping your data, which means stuff you will need includes:
1. adb and fastboot on your computer (I am using mac but you can find it on windows as well. There are tones of website and forums telling you the latest method of getting it onto your computer)
2. factory image of nexus 4(I use 4.4.4, since that's what it was. I don't have the time and energy to try to do the same thing with lollipop. you can try can leave a comment).
update: do NOT try to flash 5.0 rom using this method. You will be stuck at boot loop again
3. usb cable
4. nexus 4 with unlocked bootloader(the process of unlocking bootloader will wipe your device)
5. computer
steps
1. unzip the factory image (something.tgz)
2. for me, after unzipping the .tgz, I still find another .zip inside. unzip that too.
3. hold vol+, vol-, and power button simultaneously to enter fastboot mode
4. open terminal(mac)(it would probably be cmd for windows)
5. connect your nexus 4(in fastboot)
6. to make sure it connect successfully, type "fastboot devices". if something like "005040c0d54bb291 fastboot" appears, you are good. Otherwise, try reconnect your device/boot to fastboot again/use another usb cable
7.now we need to tell the terminal to navigate to the location of the unzipped factory image. to do that, i suggest you put the unzipped folder to somewhere easy to find, like desktop. these are some commands to help you navigate:
"ls" allows you to look at whats inside the current directory of the terminal. For example, this is the output after typing "ls" for me:
some folder Photos
nexus4image.tgz how many folders do you have
5.zip occam-ktu84p
more folder occam-ktu84p.zip
after knowing where you are, use "cd" (below) to go to your folder
"cd" means change directory. For example. "cd Photos" will brings me to the "Photos" folder. And then if I type ls, I will see a whole bunch of photos in my photos. If you go to the wrong folder, type "cd ..", and it will bring you back to the previous folder.
8. flash bootloader.
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash bootloader bootloader-mako-makoz30d.img
9. reboot bootloader. just copy and paste
fastboot reboot-bootloader
10. flash radio
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.03.img
11. reboot bootloader. just copy and paste
fastboot reboot-bootloader
12. flash system
system.img is located inside the zip, use ls to help you navigate. This steps takes the longest time, total time on this step is 87 seconds while the others are less then 1 second
fastboot flash system system.img
13. flash boot
boot.img is located inside the zip, use ls to help you navigate.
fastboot flash boot boot.img
14. flash recovery
fastboot.img is located inside the zip, use ls to help you navigate.
fastboot flash recovery recovery.img
15. format cache(not the memory, so everything should be fine)
fastboot format cache
16. reboot and wait
this will reboot your device. You probably have to wait for a while to initialise all the apps. after than you are good to go!
fastboot reboot

Hello, I've just recently flashed lollipop to my nexus 7 2012 WiFi and every time I try to enter recovery I get a "No Command" on my screen. Have i messed up something whilst flashing? I've tried flashing lollipop twice with no luck for getting into recovery. Any help much appreciated.
Does your tablet boot into Android? I tried the OTA update on modified stock android, and it failed locking me out, it would boot loop 3 times, then go to the 'No command' - you need to hold all three buttons, power and both the volumes when it's turned off, then it should boot into fastboot with recovery options. If you are stuck on 'no command' - if you hold power and volume up you'll get some options including reboot.
So from fastboot, I didn't do anything here because recovery didn't work for me, but if you are in fastboot, I connected it to my PC and opened nexus toolkit - I had no ADB access but fastboot was available, so I had to flash individual images using that software. So I downloaded the IMG files for android 5 for the nexus 2012 manually, its a tgz archive, extracted it and there was another tgz archive inside which had the individual files I needed to flash. Boot.IMG and system.IMG are the main ones.
I assume you have the drivers set up anyway on your PC, in nexus toolkit I went to Advanced and in the first column near the top I clicked Fastboot, then in the next column at the top, I clicked the permanent option, and below that in the middle column it lists all the android flashable files, boot, recovery, system, user data. These will match your files in the archive that was inside of the IMG archive you downloaded from google, boot.IMG, recovery.IMG, system.IMG, user data.IMG. I only needed to do flsash boot and system, recovery didn't work as it said it needed ADB access, and I didn't do user data as I don't think it was important and it wasn't necessary.
I naturally flashed boot.IMG first, then I had to flash the system.IMG twice as it didn't seem to do anything the first time. The second time it took 2-3 minutes then rebooted, and started booting into Android 5, the first boot will take 10 minutes.
This is probably a lot more than what you wanted to hear as I'm unsure of your problem, but I had to figure this out myself through using knowledge on flashing my old Sony Ericsson which was harder back then. I've only used the nexus toolkit once so it was still new to me. Anyway if this doest help you, I'm sure now its here other people will find it who need it

I'm having same problem. Have you had any success in repairing this issue? If so please let me know the fix. Thanks.
It's there you just have to hold power and up when you see no command.
Hi guys!
This is my first time on this website and I'm here because I need the help of you!
Yeah, I do have a Nexus 7 (2012), it was on 4.4.4 root. Of course, like an idiot, when I saw the OTA of Lollipop, I download it and install it right away. Of course, I didn't unroot before...
So yeah, actually, I'm stuck in a loop between the tablet rebooting and the "No command" section (I guess it's name recovery)
All this was yesterday. That night, I tried everything I could try from my expertise. I've used the Nexus Root Toolkit to flash stock + unroot but with no succes. The main problem is that the only way for my N7 to be recognize by my computer is by "Apply update from ADB" (Sideload from recovery). So my driver aren't good for beeing use with the NRTK and I can't do anything... Then, I can't fastboot or anything, if I try something, It keep rebooting up.
So I hope I've been enough clear. (I'm french so )
Please, take the time to help me! This N7 is very important for me!
Sincerely,
Gabriel
