[Q] Booting into recovery shows "no command"

Hi there,
yesterday succesfully rooted my device using the insecure boot image.
Today booted and also flashed the new CWM recovery image but now, when booting into recovery only get an android logo and the text "no command" ?
Any ideas ? Flashed back to original recovery image but no change either ?
Root remains though and working fine.
Thanks

Not true read here again :
UPDATE: There is an official ClockworkMod recovery for Nexus 4 now available directly by Koush, so this should all be easy as pie now and you can now safely install CWM too. I am updating the CWM method with the updated instructions.

It seems tonight clockwork will release a new version with bugfixes which should make recovery working when flashed also.
Sent from my Nexus 4 using xda app-developers app
New clockworkmod recovery 6.0.1.8 had been released and I can confirm myself that it is working perfectly and stays when flashed !
You can download it here and follow the instructions as written here.
Good luck !
excellent, i was waiting for someone to confirm before flashing it myself

Meanwhile a newer 6.0.1.9 is released as well, which will hopefully also fix the backup being in the wrong location and not usable
CWM is fixed. Read this thread: http://forum.xda-developers.com/showthread.php?t=1995440
6.0.1.9 is the one i flashed and I'm still looking for my backup :s

Disregard this post! It was meant for LBE which is a Virus or acts like one (Newest version that was translated)
I'm having the "no command" message as well. I've flashed CWM 6.0.2.3 no-touch (following this guide), and it doesn't seem to be sticking. It'll work the first time, but then revert to the "no command" screen. I've also tried flashing the stock recovery, and then I receive the same message. I have an unlocked bootloader, and I managed root via the same guide. Anybody have any ideas?

From efrants android 101 sticky:
I just flashed CWM, but every time I try to boot into CWM, I keep seeing the stock recovery. Why?
If you updated your Android build using an OTA update file (either manually or over-the-air), the update placed two files on your device that re-flash the stock recovery every time you reboot your device. These two files are:
/system/etc/install-recovery.sh <== this is the script that installs the patch file
/system/recovery-from-boot.p <== this is the patch
You have to rename (or delete) one or both of them, then re-flash your custom recovery. Now it will stick.

Perfect! Thank you! I had just previously downloaded 4.2.1, and so renaming recovery-from-boot.p did the trick. I had to remount my /system as read/write (used Total Commander, and it worked like a charm.

[Q] OTA update to 4.2.2 problems

My 7 is unlocked and rooted, using Nexus Root Toolkit. I did an OTA to get to 4.2.1 some time ago and that went well. Root and unlock persisted. I am now getting OTA options for 4.2.2 from the System menu. First time I got and error in Android's belly. I restarted and was still in 4.2.1. System then said that I was up to date. A week or so later System told me again that OTA was available and I got the same result.
Any suggestions as to how I can do the update?

You have two choices
1. Flash the stock 4.2.2 image using fastboot from here https://developers.google.com/android/nexus/images
Or
2. Flash this in CWM recovery (note this link is for the wifi model) http://android.clients.google.com/p....signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip
You have to restore everything except relocking bootloader ... To be able to update ...when u finish ..just re-root

How do I unroot without whipping all data?
Sent from my Nexus 7 using xda app-developers app
Search this forum for "OTA debugged"
There are only a few threads - read them all before you take any action.
This particular problem appears to be caused by StickMount.
You don't need to delete everything, nor do you need to flash the ENTIRE stock image - only the boot.img and system.img (via fastboot) without doing a factory reset or any other wiping.
This will unroot the ROM, and (of course) prevent StickMount from working. So you should over flash a SuperSU root kit afterwards (via custom recovery).
This very same problem may recur on the next OTA - so for goodness sake's, make a nandroid backup before you re-install StickMount and give it root privileges.

Sorry for being a numpty... can someone put the above into a mini step by step guide for me.. I'm stuggling with the terminology.
I rooted my Nexus and have since forgotten anything techie regarding it. I have StickMount and cannot update to 4.2.2..
How do i flash boot.img and system.img via fastboot, where do i get these files from, what versions etc do i need? And over flash SuperSU root kit?
What is OTA?
Basically, I think i need a newbie guide. I am techie enough to achieve most things normally.. i just don't know the android system at all, and what i did know to be able to root it i have completely forgotten!
Any guidance would be very much appreciated. Cheers.

looks like your SystemUI.apk has been modified not in original. I would recommend to get copy of systemUI.apk from stock 4.2.2 and copy it to your tablet and using file explorer, replace it. and give a try.

my OTA failed too, different error. this usually always the case if /system/ folder integrity check failure (error 7), means files in /system/ folder are not original or modified. Yours does not give any details, but I bet it is. to see what error, try to flash it thru CWM or any other custom recovery you use.

I guess I'll download the Nexus Toolkit, click on the flash stock + unroot button, so it flashes the stock 4.2.2 and then I'll try to OTA update again.
I already unrooted, but I think it's not a problem.
Seems like it is not fixable!
I used fast boot to push my missing file.
I used es file explorer.
I used titanium back up to make the app, system...
No way, nothing. Not the slightest luck.
(My missing app is xt9ime.apk)
I haaaaaate this situation.
the worst thing is that xt9ime.apk is asus keyboard, and it is disabled by google on nexus 7.
why should not having an app that they don't want to use be a problem. X(

Are you guys with errors using SuperSU? If so what version?
It seems like that the last couple versions touch a file used by OTAs. The Dev recommends using the "Full Unroot" option in the SuperSU app prior to accepting the OTA.

I did full unroot, and I also did a factory reset, but it still fails to install.
Using Wug's Toolkit to flash stock 4.2.2 is a good idea?
Then try to OTA update 4.3 again?

You cannot install the full image from Google using fastboot? Just back up your data(if you can) then try a fresh install.

Sadness.
Fastboot is a utility used to control the base fastboot firmware on many Android devices. It lets you do low-level actions such as flashing a custom recovery, ROM, or kernel. Toolkits run fastboot behind the scene, but automate the commands for newer users.
I had exactly the same problem and after trying a few things, I just found a working solution for my Nexus 7.
I used the same tool I used to unlock and root a few months ago: Nexus Root Toolkit 1.6.3.
I made a backup of my files first, my idea being to reflash the 4.2.2 rom
I downloaded the system file here: https://developers.google.com/android/nexus/images#occamjwr66v
Then, in the Nexus Root Kit, launch " flash stock + unroot" and select the downloaded system file.
The flash lasts 5 minutes, and the system will reboot.
Then you need to reactivate the usb debugging .
The next action is to relock the Nexus, with the "OEM Lock" in Nexus Root Toolkit.
The system will reboot after flash.
Then, the 4.3 update will be available automaticaly but this time the installation won't crash.
I hope this could help.

I wanted to save my data and wasn't sure if going directly to 4.3 would be safe. Was just being cautious and letting the OTA do the update.

How do I manually re-root 4.3 and update SU binaries?

I was rooted on 4.2.2 and checked for the system update for 4.3. It was there so I got really excited and installed it immediately, without writing a thread about it, making sure I'm not doing something wrong. Well, I was.
It updated to 4.3 and it works fine, but I can't access TWRP (I get an opened Android with a red X over it). Also, when I go into SU, I get a message saying "There is no SU binary installed. ... If you've just upgraded to 4.3, you need to manually re root your device."
How do I do this? Thanks.

Toolkits cannot flash the recovery on Android 4.3 so you have to download the recovery image and flash the recovery image using "fastboot flash recovery [Replace_this_with_image_name]" and enter while your Nexus 4 is on bootloader mode to flash the recovery properly.
Now you need to transfer the SuperSU v1.51 zip file to the root of your internal storage and install it via TWRP recovery and then you are fully rooted without any TB restore issues or anything like that.

I rooted and unlocked my device with a Toolkit but the problem is that you do not know what is exactly going on since you cannot see the commands.
You have to get the Android SDK for this one, I already have it all in a zip file but that is on my laptop and I will be working on my phone today by installing PA.
One you get the SDK you have to go into the SDK manager and download/update the ADB tools, after that open the CMD in the folder which says "Platform-tools" and type the command from there.
Has for the image you have to put it in platform-tools has well for this to work:

You don't need to flash the stock image and lose your data, but even if you are on stock 4.3 you still need two things: stock recovery (if you don't already have it installed) AND you need to unroot! Being rooted will throw the Status 7 error.
Here's what I did:
First flash the stock recovery for JWR66V in fastboot.
Then use the "Full unroot" option inside SuperSU.
Apply the JWR66Y update using ADB sideload.
Then reinstall TWRP and install UPDATE-SuperSU-v1.51.zip using TWRP.
After rebooting you may be surprised to see that the SuperSU app needs to be installed again (seems to be a quirk a lot of us are having). Just head over to Google play and after that all should be good.

Hi, I'm looking forward to doing this step since I really want to get that OTA installed in my device. Mine is on stock ROM, rooted via wugfresh toolkit. My concern is, after doing this step, will I lose all data? Also could you please explain how to do the first step- "First flash the stock recovery for JWR66V in fastboot."? I'm still a bit new to all these things, so please bare with me.

Check out this thread. I flashed the Grouper.zip file, which is the OTA modified by commenting out the validation check that results in the Status 7 error. I copied it to /sdcard along with the Supersu 1.51 zip. The ota flashed perfectly using TWRP recovery. After booting and going back into TWRP, I flashed the supersu1.51 and regained root. You do not need to unroot or flash stock recovery to get this update. No data loss. I'm stock rom & kernel, rooted with TWRP recovery.

You won't lose data if you repeat the steps I took. However since you are asking how to flash a recovery in fastboot I would seriously be careful and do a bit of homework on how fastboot works. All the instructions you'll ever need can be found by searching xda. It really isn't as daunting as it sounds but you definitely need to understand how it works before trying it.
Or you could try the link that Groid posted if you aren't concerned about skipping the validation check. The process is definitely is simpler if you're "new to all these things".
I'm not opposed to using WugFresh's toolkit, he's a brilliant developer, but it's never a bad idea to learn about what happens in the background and see it with your own eyes.
