Going into CWM - Nexus 7 Q&A, Help & Troubleshooting

Hey guys... Just rooted my Nexus 7 and for that matter any android device for the first time. I followed ToolKit 2.0 and did the one step for unlocking boot, rooting, flashing CWM and all option and successfully rooted. But however i am having trouble going into CWM mode.. Can someone please help me. I tried going into the power button and volume down button mode and with the volume keys went to 'Recovery Mode' but then the device just goes blank and then Google comes up written and nothing else happens. I then installed this app called ROM Manager via which i am able to boot into CWM. So how do i do it without the app. Please help me out guys.. Thanks a lot

You need to plug the device into a powered USB port on the computer and manually entering recovery will work. It's a glitch in the nexus bootloader for the time being.
Also, the Trinity kernel toolbox app and maybe goo manager work for going to recovery, and the roms advanced power menus with the reboot to recovery option will work. The app quick boot may work too. But for using the volume rockers you need to be connected to USB

You could also use adb "adb reboot recovery"
If you don't have a pc near you, download the Android Terminal Emulator and type
su (hit enter and grand the superuser permission)
reboot recovery (enter)

Me too sometimes my device wouldn't want to go into recovery from the bootloader. I would have to pass from an app such as Rom Manager to reboot in recovery or it would get stock on Google logo.
What I did to solve is to :
./fastboot erase boot
./fastboot format system
./fastboot format cache
./fastboot format userdata
then from there I could boot into recovery and flash any rom I wanted to.

I'm pretty pissed because clockwork has been nothing but trouble on the Vision the Ville and now the Grouper and I keep forking pocket change to koush for his little touch recovery and it is still buggy. I can't believe this problem of not getting f to recovery from fastboot without needing anything else.
so I'm doing a fastboot erase recovery to wipe off that clockwork and then fastboot flash recovery teamWINifitaintbrokedontfixit.img

Fastboot mode - no boot or recovery img **help**

Hi
I've searched for a solution but didn't find one for my problem so...
I was trying to flash an updated kernel through Kernel Manager application and then it said it cannot complete task and asked me to reboot system.
I then entered into the recovery and flashed the kernel manually.
When rebooted system I got the message "FASTBOOT MODE - NO BOOT OR RECOVERY IMG" in red at the top of the bootloader.
So naturally I thought maybe it lost the recovery so I went and flashed CWM recovery 3.0.2.5 (had 3.0.2.4 when all this happened) through fastboot and that went OK.
I then entered the recovery to make sure the recovery flashing went OK and pressed Restart system now.
But then it started the bootloader and the same message appeared "FASTBOOT MODE - NO BOOT OR RECOVERY IMG" in red at the top of the bootloader.
I repeated that process few times and same thing.
The strange thing is when I select "REBOOT BOOTLOADER" and it boots into bootloader I see "FASTBOOT MODE" in red at the top. But when I try to reboot the phose I see the message to the top again.
How can I get out of this?
Hi guys,
I've got the same problem, although I don't know if it IS a problem.
I'm running v7.0.0-NS and I'm going to upgrade to v7.0.3 ... just searching for instructions!!!
~AndrewGoldy
since I am able to enter the recovery Im trying to restore an earlier backup. Not sure it this will do anything since my problem is in the bootloader area.
If this makes my phone to start up normally then I really dont understand this.
*** I think that I've just fixed it ***
I opened up "Rom Manager v4.2.0.2", and then selected the option to "Flash ClockworkMod Recovery"
Once it had downloaded "ClockworkMod Recovery v3.0.2.4", I selected the option to "Reboot into Recovery".
That worked.
It now says "Fastboot Mode" when I boot into the Bootloader.
Success!!!! (I think)
Well it just finished restoring the backup.
It seems it solved the problem on mine to since it passed the bootloader and the boot animation is on.
I really cant understand this.
I've done the same but the Recovery Stil nor Bootloader works. However it does say Fast boot mode now instead of no boot or recovery img. But still can't flash or back up a rom!
Correction i got it work after flashing to oldest recovery that was an option
I fixed this problem (Nexus S) by reverting to an older (3.0.2.4) CMRecovery, just go down to the last option "All ClockworkMod Recoveries" and Flash an older version (mine was not working with 5.0.2.0).
Hi! Anyoane can help me ?
I disconnected by accidently the USB cable while the phone was at the ClockWorkMod Recovery v5.0.2.0/-mounts and storage/-mount USB storage, and after that ( adb , fastboot and usb died).
I installed Stock OTA 2.3.6 I9023 for my Nexus S I9023. During the day phone closed and no longer wanted to open (even replace the battery). After more hours the phone is open , adb and usb works not for a long time after several attempts ( during this time I managed it to root and install CWM 5.0.2.0 back)
I flashed ICS Kwiboo v3 . After reboot the phone began to froze , and shortaly closed.
Because the phone will no longer open I tried in CWM all ( wipe data:fact, wipe cache, wipe dalvik, format/all ) .
Now if reboot system on CWM I have Fastboot Mode - No Boot or Recovery IMG
but if I reboot bootloader or power off when is opened is just Fastboot Mode .
Adb , fastboot and mount USB still no work. ( I have SDK 14 on windows7 installed, all the driver for Nexus S was updated).
Because the PC not recognized my phon I can't install another ROM or CWM.
( When USB cable connecting on the phone it's charge the battery only!).
Thanks for your advice!
No recovery img & fastboot devices -> nothing
Hi all,
When I try to access the recovery mode on my NS, I have the same "no boot or recovery img". I change my CWM version from last to 3.0.2.4 and another version too. Still, I can't access the recovery mode.
I installed the SDK to restore a stock recovery image I found, hoping to use fastboot (from the sdk + a standalone version I found before). But it won't recognize my phone (fastboot devices -> nothing). I installed the PdaNet for the Android 1.0 driver, and the Android 4.0 driver from the SDK. Still nothing, although "adb devices" apparently sees my phone.
I've spent my whole night on this. Without recovery I can't backup, and I can't switch rom (heard of this ICS rolling-out ? I'd like to have some flavour of it), I can't wipe or whatever.
Please can someone point me to a solution for fastboot to see the phone, or even better, to reinstall a recovery tool ?
Thanks a huge lot

I can help you but....
1. In bootloader mod ADB working ? (if not try back off battery for 10 min or more) and try again..
2. Your device is rooted ?
I was going to suggest trying to reflash the latest recovery again in CWM, but I think you guys said that hasn't worked.
Every now and then when I flash a new ROM this happens to me. I usually just flash an older version, then reflash the newest version and the Recovery works just fine.
Maybe try using a different recovery program?
it does work, many have done it already, see all the duplicated topics

1. I removed the battery for 10mn. When I come back to the bootloader "ADB devices" doesn't return a device, so it doesn't see my phone. But when switched on, it can see it.
2. Yes, it is. There is the SuperUser app, and when apps ask for root, I can allow or deny. And the lock state is 'unlocked'

I tried the latest, the oldest, the versions inbetween... nothing. I have the latest version of CWM and I reflashed the last Recovery from the app.
I can't flash another ROM, because I need recovery mode for that ; and my problem is that I can't access recovery indeed... :/ I feel like I need A to do B, and B to do A.
"No boot or recovery img": doesn't it mean that I should put some file somewhere ? I hope it would be that simple.
Do you have other ideas ?

I've tried several time, flashing different versions of CWM recovery. I've returned to bootloader -> recovery dozens of time and I still have the "no boot no recovery img". I'll try again.
All the threads which speak about it and mention to flash another rom -> yeah thanks, but I can't access recovery
Threads mentioning fastboot -> I tried with different drivers (including 1.0 and 4.0), but fastboot won't see/talk to my device
Do you see something else that I didn't try ?
---------- Post added at 02:16 PM ---------- Previous post was at 01:33 PM ----------
I also tried this which seems to be a good step
http://forum.xda-developers.com/showthread.php?t=1356319
Basically it says
adb shell
SU
flash_image recovery /sdcard/filename.img
But like the guy in thread, I have memory errors "mtd: read error at 0x00000000 (out of memory)" then write errors, then "failed with error: -1" and "error writing recovery"
It's ok now.
In case other it can help other people:
I tried again the PDAnet installation to get the android 1.0 drivers. (actually there is a binary called "install legacy usb drivers" which apparently worked well.)
Fastboot would detect my phone in bootloader mode.
So I could "fastboot flash recovery xxx.img" I first failed with a stock recovery, but for which I didn't know the exact reference and origins (I was stuck with the exclamation point in white triangle). As I couldn't find another stock recovery for Nexus S, I downloaded the CWM recovery from the website (not from the app), last version (5.0.2.0) and flashed it with fastboot.
It seems to work properly now, so i'm doing a rom backup, just in case for later, and I'll flash stock ICS
FYI: rom manager only caused me issues ; I don't know why Cyanogen uses it. Just use the recovery directly from recovery... Even CWM. just not Rom Manager.
Cheers and thanks to those who tried to help.

THANKS! This helped A TON!
I did the PDA installation again, and for some reason this seemed to fix my inability to access recovery.
Agreed on Rom manager, I updated CWM through rom manager and I believe that's what buggered up my recovery, as I have never had trouble accessing it before I did that.
But again, a big THANKS for that suggestion!

Help! twrp not loading!

I just used this method
""Enter the following commands to flash TWRP Recovery on your tablet:
adb reboot bootloader
fastboot flash recovery openrecovery-twrp-2.2.1-grouper.img
TWRP Recovery will then be flashed on your Nexus 7.
You will also get a “Finish/Okay” message at the command prompt. Type this command to reboot your tablet:
fastboot reboot
To enter TWRP Recovery, switch off your tablet. Press and hold the Volume Up, Volume Down, and Power buttons together.""
to install twrp on my nexus 7(rooted and unlocked with stock ROM).
It went well but when i try to boot it into recovery mode from bootloader, its just stuck a the google symbol screen.
I tried an alternative, using goo manager. when i reboot it using goomanager, it goes into twrp but not when i manually reboot the device and go into bootloader mode... Please help!!!!!
There's a bug in the boot loader that requires you to be plugged into a computer to access recovery.

as previously mentioned, there is a bug.
I can boot into TWRP via hold Power button -> Reboot -> Recovery, if your ROM [stock rom?] does not have this, download ROM Toolbox on Play Store, and select "Rebooter" on the bottom, and "Reboot recovery"
Or I think you can use Terminal Emulator, and type
# su
# reboot recovery
that should work too..
or you can just plug it into a computer
Thanks a butt load!!!!!!!!!!
I also think goomanager or rom manager has a bug that it wont let me power on my tablet unless i hold the power button down for 10 seconds. I remove those apps then all is fine.

Went to boot into recovery and the damn thing is stuck. I can move around up and down with the volume buttons but i cannot press enter with the power button. shutting it off only reboots the tablet and goes back into recovery. any ideas?

Can you get to the bootloader screen so you can use fastboot? If so try flashing the TWRP recovery, it's a great recovery.

I can press the power button and both volumes and it gets me to download mode... from there, every option i try just gets me back to recovery. when i press start, it sends me to recovery. when i press shut down and then turn it on - recovery. when i press restart bootloader, it still takes me to recovery afterwards. wtf happened here man? never seen this before.

If you can at least get to download/fastboot mode, either get the stock recovery.img file or extract the recovery.img file from a custom_recover.zip, such as CMW or TWRP and place it in the directory where you have the fastboot util on your Windows PC, plug in the device into your Windows PC. Then type the folowing in a Windows Command prompt(without the quotes): "fastboot flash recovery recovery.img". Once that finishes then try rebooting back to recovery.
If you that doesn't work you may have a damaged bootloader, you can try extracting the bootloader(bootloader-manta-mantalj12.img) from the stock ROM and flashing it with the following command: "fastboot flash bootloader bootloader-manta-mantalj12.img" then you can type: "fastboot reboot-bootloader" to reboot directly to the bootloader.

This happened to me yesterday.
Step 1 - hold down the power+volume up+volume down
Step 2 - plug up USB cable and use fastboot to flash the "touch" recovery version. Usebthe method as before, you might need to point your machine to the "naked driver" in dev section to get windows to see the fastboot device driver.
Step 3 - once you are in touch recovery you can just use the touchscreen instead of power button

You can just "adb reboot" from any computer with working adb and drivers.
This needs to not be flashed by default from Rom Manager until they get it taken care of. Twrp and cwm touch work just fine.

Seriously. Can we please sticky a thread or something that says CWM isn't stable on the nexus 10 yet. It would save a lot of people a lot of trouble.
I had the same issue get rid of crappy cwm and flash twrp, flash it by downloading the 1.3 nexus 10 rootkit selecting option 6 i believe with your n10 connected to your pc, it will fix your issue

[HELP]?Bricked Nexus 4!

SO long story short I followed the rooting guide below:
http://forum.xda-developers.com/showthread.php?t=2266654
What I did:
I Unlocked Bootloader & Installed Custom Recovery, but after
I clicked Reboot, TWRP prompted me to "Fix Root Permission"
and install Root, which I made the grave mistake of swiping to
accept..
Now everytime the phone boots I see a "Google" Logo with a padlock
underneath, for a good few minutes, then a never-ending bootloop!!!
I can get into Recovery, but I can't see the Phone connected to any of my
computers, So I am unable to add in a file to flash and possibly fix my Nexus...
(I also can't mount, nor can I wipe anything except cache)
Please please please, is there anything I can do to save this phone???
:crying::crying::crying:​
When you're in recovery mode you need to use adb to transfer files to your Nexus. Look for a howto that tells you how to use it.
Go into recovery and factory reset. If it still bootloops go back to recovery then on your PC go to device manager. Plug your phone up and see if it starts trying to update the drivers if it does stop it and manually direct it to the driver folder and let it install. Download super SU and use adb to push it to the phone
adb push su.zip /sdcard/
Flash it in recovery then reboot

There is a sweet yummy feature in recovery called "adb sideload". Boot into TWRP recovery -> Advanced -> ADB Sideload.
Typing "adb sideload path-to-your-flashable-zip" in the command line will send the zip to your phone and flash.
Nothing seemed to work however I got it working using one of the tool kits that was able to pull me out of the boot loop in the bootloader thanks guys

Hold your power button for 15-ish seconds (even hold it for a while when the screen is black)
After that, hold the volume up+down+power button this will boot you into the bootloader.
After this you can just simply push a rom through adb on your phone, or try the factory reset in the recovery mentioned above.
so finaly how you decide your problem? cause i have the same problem

Can't boot or flash to TWRP or CMW

Today I tried booting up to recovery (power+vol down), after choosing Recovery Mode from the menu and hitting Power button, it gets to a screen with the green Android guy with a red triangle and just stays there.
So I rebooted the phone. Launch Nexus Root Toolkit, I tried to install CWM or TWRP, neither works. It gets to the same recovery mode and gets stuck there, only this time, it gets stuck on the Google logo instead of the Android guy with red triangle. I even try to flash stock recovery, and it also doesn't work.
Why can't I get into CWM or TWRP nor can I flash them?
Thanks for any help.

Be sure u are bootloader unlocked.
Android guy is normal... Is a safety step before entering on stock recovery, to pass that: hold power and hit once volume +
Probably u cant flash images cuz fastboot isnt working(old fastboot.exe file), wrong recovery file,...

Bootloader was unlocked. I launched the CMD Prompt from Nexus Root Toolkit and ran the fastboot command to manually flash the downloaded CWM and it worked.
Code:
adb reboot bootloader
fastboot flash recovery recovery-clockwork-x.x.x.x-mako.img
So maybe something's odd about the simple one-click utilities in Nexus Root Toolkit that is not working.
Thanks for the help nonetheless. :good:
