Unlocked but can't root/install CWM

I used the toolkit for mac and it unlocked me, but when it came to the next steps it said device not found and then told me to highlight recovery and press start, when I do I get the android with the red ! symbol.
Can someone help me?

That symbol is a security feature within the stock recovery, volume up and power to access the stock recovery.

I tried that it's not working I press up then power the phone reboots and the red ! symbol shows up...
I searched and saw hold power and press up when I see the red ! but it just reboots the phone...
help please?

edit my adb now won't recognize my phone even though it did a few mins ago...
I'm frustrated, been trying to access the stock recovery for the past several mins and simply can't.
help please?

For me also Stock recovery never worked. Just try to flash CWM or TWRP.
Btw, What toolkit did you use and how did you install the drivers. Please answer these, so that someone can help you better.(Or is it just the 'mac toolkit' ?)
My suggestion: PLZ DO NOT USE TOOLKIT. If you are stuck at some point while using the toolkit, then you'll not know what went wrong and how you can correct it. Do it manually. It is the most hassle-free method. Trust me.
I think that ADB will not work in stock recovery(may be you can boot normally into your phone and then try adb). The thing which you are looking for is 'fastboot'.
1) Restart ur phone (Power Button + Volume Down, i guess) and land in the bootloader and connect your phone to PC.
2) In CMD prompt(or Terminal), type 'fastboot devices'. If your device gets listed here, then fastboot is working and drivers are properly installed. If not, then drivers are not properly installed in your PC. You need both ADB and FASTBOOT drivers. Install them properly.
PS: For MAC, i think the command is slightly different. Something like './fastboot devices' . Please look for the same in this forum or just google it and find out.
3) Follow this guide for flashing CWM and Rooting.

4) For properly installing the Drivers, read " A. Install the drivers " in the below thread (actually you can read the entire thread )

My knowledge is limited to Windows PC, sorry if I am not of much help. Thanks !

I used the nexus 4 Mac rootkit I found in here.
It unlocked my phone fine. But when it came to installing a recovery and root it didn't.
Neither my adb or fastboot are working now before I unlocked and I messed around and they worked now nada ...
I went to YouTube saw my problem tried pressing volume up and power like in the video and it just gives me a black screen and either turns the phone off or reboots it normally...not sure if in supposed to hold power and let go of volume or vice versa.
I placed all the files on the storage I just need to access stock recovery which I strangely cannot now...
Tried framearoot and got nowhere.
Very frustrating

Just as I mentioned, i also had the same problem with stock recovery. So I simply flashed a Custom one(CWM, in my case)
Get the ADB and FASTBOOT working and that'll solve your recovery problem. Try fiddling with your drivers again. Not sure how to do that in MAC. If FASTBOOT is working, the you can boot into a Custom Recovery(you need not even flash it) and perform whatever you need to.
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
Again, look at the efrant's guide i referred above; i took this from there only.Remember to replace 'customrecovery.img', with the actual downloaded custom recovery image name.
Or you can try posting your problem with the toolkit, in mac toolkit's thread.

I have been youtubing everything and finally got to
Reboot system
apply update from adb
wipe data/factory reset
wipe cache partition.
I now can get adb working so I tried ./adb sideload cwm from my desktop and it is giving me signature verification failed. installation aborted.
What can I do to resolve this?
I searched xda and no one can solve this issue from the threads I've read.

I fixed it! Whooohoooo! Installed cwm and root ....now to install pa rom.
Thanks for the help!

[Q] I have a broken N7.

*** Returned my N7 (2012) as faulty and swapped with a 2013. Thread Ended. ***
I've been having trouble with my N7 (2012) for a while now.. Ever since the 4.3 update.. Slow response, hangs, and so on.
The latest 4.3 update would not install. Just a lying down droid with '!'.
My tablet was rooted using Wugfresh toolkit and was perfect before 4.3.
So i thought i'd go back to the start and use the toolkit to go back to root and flash stock+unroot.
Went through all instructions, it got to the part where it says ' You tablet will now reboot a few times. Please wait.'
Waited for 30 mins and nothing..
Now got a tablet with the google name and the unlock symbol. Options available are start, bootloader, recovery, off
All bring back to same screen.. Bootloader option displays -
Fastboot mode
PRODUCT NAME - tilapia
VARIANT = tilapia
HW VERSION - PR
BOOTLOADER VERSION - 4.13
BASEBAND VERSION - 1231_0.18.0_0409
SERIAL NUMBER - 015d88ffa8540a1c
SIGNING - not defined yet
LOCK STATE - UNLOCKED
During the flash boot to stock it wiped all directories etc so I now have an empty tablet..
Any ideas what I can do now? I would prefer to go back to stock 4.2 if possible... but if not, any help would be nice...

Hi, filking...
I have no experience with toolkits, so I can only advise you to download the Factory Image for your 'tilapia'/'nakasig' Nexus 7, and fastboot flash it.
Using fastboot isn't that difficult, and I'm at a loss to understand why toolkits have become so popular, when fastboot is so easy to use. Maybe people don't like command line interfaces...??
Anyway, there's a thread here which explains it all in detail.
Good luck.
Rgrds,
Ged.

Hi, thanks for the reply.
I think, in the world it is now, everyone is used to menus/mouse clicks to perform functions.
Anyway, I have read that thread already and my problem is when I get to the commands. All 'adb' commands don't work.
'adb devices' shows nothing.
I've tried in bootloader mode and recovery mode... All show a droid lying down. Fastboot mode shows the above message. Rest show, 'boot failed'
Help.....

You don't need ADB to flash a stock image. ADB only works with a fully booted Android tablet. Indeed, if you have no bootable OS on your tablet, ADB is redundant and will not work.
You need to use fastboot...
What do you see when you type fastboot devices? (whilst the N7 is booted into the bootloader).
Rgrds,
Ged.

An update....
I went through wugs full driver setup part and deleted existing drivers. Installed the drivers again...
The device is detected on my PC.. But, seeing as it is stuck on the bootloader screen and I can't get into the system to turn on debugging, no adb commands work.
Device is listed as an 'unknown' android device when plugged in..
Seen a few other posts similar, but a lot say, 'it's ok, i've fixed it' without saying how.
anyone?

sorry, our posts must've been at same time..
Fastboot devices shows
015d88ffa8540a0c fastboot
*EDIT* Looks like i've misread the instructions in the post linked to above...
It got to the part where is said 'type in adb devices'... I read that, it didn't work, and I stopped.
BUT, I was already in bootloader mode, so didn't need that bit..
My error. (it's been a hot day!!! is that a good enough excuse.)
Continuing with the fastboot commands now... I'll update how it goes..
Thanks for replies.....

Update. All resolved.
I tried with the 4.3 img, but for some reason, it went through all the steps correctly. fastboot reboot resulted in the bootloader screen again.
Weird I thought, so I downloaded the 4.2.2 img and tried that and it worked perfectly..
Many thanks all who did, and it's a reminder to all. Re-read instructions..

No Command Error

I went to update to KitKat and it was nearly done and then the "No Command" error came up. My tablet has an unlocked boot loader but isn't rooted. However it was before but I updated it from an OTA and that got rid of it. I've tried booting into recovery etc but the same thing happens.
Anyone have any advice please?

Same exact issue and set up here. Also, maybe I'm just dumb, but I can't get my tablet to turn off either. It just keeps cycling back to the "no command" screen until I do something.

I think that both of you what you see (the "no command") is your stock recovery, if indeed you see an android with a yellow !.
If it is the case to access the menu of the stock recovery press power and tap volume up. The menu will give you the choice of rebooting your Nexus 7.

I can get to the menu but when trying the reboot option, it just cycles the same way again. Back to the android with a red ! and says "No command." I also tried clearing cache and data to no avail. I was going to try using ADB to manually push the update but my computer was recently updated and now I can't get the driver installed for some reason.
I spent too much time messing around with and learning how to do things with my SIII and not enough time with this

Same deal here! Not sure what to do short of wiping and losing my info.

Same here...any advice? Not sure what happened. OTA update too.

Wow, this seems to be widespread, at least somewhat. I'm in same situation. Toolkits, adb, nothing works. I thought this was a soft brick, but now I'm thinking it's toast. Probably doesn't help that I didn't have Dev options enabled along with USB Debugging. I can't even turn it off. Just bootloops after Google logo shows up twice, then to No Command error, then starts over again. I wonder what the hell is causing this. (Device was locked and unrooted)

Same boat here, even sideloaded the factory image via ADB.

If you have android-sdk-windows installed on your computer do not forget to update it through "SDK Manager.exe".

Pushing via ADB didn't work for me. That also failed.
I caved and called Google. Tech support is stumped as well.

I finally got mine working again!
I tried a million different things so I'm going to try and explain my process as simple as I can, I apologize in advance because I am far from an expert...
First, I tried using the method, well some of it, from this thread: http://forum.xda-developers.com/showthread.php?t=1907796
- I would suggest using this thread to get everything set up (drivers, ADB, the factory image downloaded and in the correct file location) I wasn't able to get the drivers working correctly with that route so I ended up using the toolkit to get them working but that thread helped me get all of the system files in the correct location and helped get all of the ADB stuff set up.
Once you have everything set up and your computer recognizes the tablet, (I checked that by opening a cmd prompt and using the command from the original thread above "adb devices"). As long as you see your device, I think you should be good.
From the "No Command" screen I held down Power and Volume + to get the menu to come up. I then chose the Restart option and immediately held Power and Volume -. This got me into the Fastboot Mode.
Once in Fastboot mode I went to the cmd prompt on my computer and used the following commands in this order from this post:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system -w
fastboot flash system system.img
fastboot reboot
*Make sure that all of the image files are in the proper location on your computer otherwise this step is worthless
The tablet then rebooted normally and I was able to set everything up again. Again, I am by no means an expert at all, this is just what worked for me. Try at your own risk.
I hope I covered all of the steps, I tried a million different things last night so they all kind of run together.

I ended up doing and it worked for me as well. Wiped everything though. How can I restore / reinstall my apps w/o needing to download them all again?

Two things: That guide says you must have USB Debugging enabled. Since my wife had this tablet, I did not have dev options enabled at all, including USB debug.
The other thing is that when I run the SDK Manager, nothing happens on my computer. I double click it or try Run as Admin, and a small CMD box flashes on my screen for a millesecond and disappears. That's all.

My wife's 2012 N7 is having this same problem. Unlocked bootloader, but I reflashed factory image and unrooted before giving it to her. She got the OTA last night, and now stuck at No Command.
I've subscribed to this thread, hoping that you guys will have it solved before I get home from work tonight! Would love to not have her lose all her data.
(I was kinda mad that she got the OTA last night and I haven't got it yet on my 2013 N7, but that's another gripe for another thread)

Unfortunately I'm not sure on the SDK manager part. As far as the USB Debugging, I'm 98% sure that I did not have it enabled either. I think I did at one point but after doing several OTA upgrades, I'm sure it got unchecked.

I don't believe there is a way. Maybe someone smarter than myself can chime in but I had to let the play store do it's thing and re-download all of mine.

Worked for me! Thanks, I don't believe I had USB Debugging enabled either. Shame it wiped all my data though.

OK, got mine back up and running! I'll just leave what I did here in case anyone can benefit from it.
I first used Wug's Toolkit to download and install the RAW drivers. (Option #4, I believe) They were the only ones that worked for me. I followed the instructions to install them and then when it looped to the No Command screen, I held volume up and power. This got me to the menu, where I chose reboot. I then immediately held down the volume button and power to get into the bootloader screen, where it (thankfully) stopped looping. Then I unlocked the bootloader using the one-click option. Next step was to download and flash factory 4.4 image using the Soft Brick mode. Fastboot recognized my device and pushed the image. Now all is well. Close call... I've already enabled USB Debugging for my wife on this tablet so that crap doesn't happen again. She did lose all her data but she is happy to have a working tablet again instead of a $200 beer coaster.

[Q] Fastboot working, but no Android...

I have a Nexus 7 2012 (KOT49H, nakasi) which will only boot into fastboot, but not to Android.
I don't know what caused this - when it happened first I rebooted, and it worked again for another couple of days, then I got a "Google Play Services has stopped" message, so I tried to power off and reboot the tablet.... and it won't reboot!
At that time I was unaware that such a thing as USB debugging existed, so it's not been set... Indeed all I know about these problems now is what I've found out here... so sorry if I test your patience!
What I have done:-
I have tried a factory reset, with no effect.
Tried Wug's toolkit, which was unable to do anything (as USB debugging not set?)
(Windows 7 appears to have the drivers for this - it appears in Device Manager as Google Nexus 7 Bootloader interface)
Tried Skipsoft's Toolkit, which succeeded in unlocking the bootloader, and I have flashed images (downloaded from google) for Boot and System to the appropriate partitions... still nothing! Flashing the bootloader image failed ("An error occurred")
Is this Nexus destined for the dustbin? It is, of course, out of warranty :crying:
Apologies if I've done something daft, but I'm getting desperate...
Can anybody help?
Many thanks

hEY,
i got the same. I tried to install cm11 and i format sd card and happens that i formated the system too.
Now i can only to restart in revory "cwm v6.0.5.0" but cant start in download modus with Power+down (see only GOOGLE LOGO with open lock sign).
With wugs fresh i got the same with the f**** usb debugging enable thing, i cant get into nothing only in cwm.
I would be sooo happy to find a tool like (adb-tool) how i can put files again on my nexus 7.
thank you guys in advance!

If you have wugs, you already have the adb tool on your computer. Look in the wugs directory. However it sounds like your drivers are messed up. If that is the case nothing is going to work until you get that corrected.

Essential Phone Half-Bricked?

Hello everyone,
I have a very peculiar problem with getting my Essential Phone to work again. It was lying around for roughly two years as I switched to another phone. Seeing as one of my relatives needs a new phone and has really low requirements I thought I could try to set it up again. I downloaded the official drivers again (Version 1.0.0 I think) as well as the last official release of fastboot images (February 2020).
Before I switched to a new Phone I had the Essential running with Lineage OS and remember wiping it with fastboot -w after I got the new device.
Now when I try to flash anything the device won't respond. It shows up when fastboot devices is used in the bootloader, but all fastboot commands get no answer whatsoever. I then switched from the official fastboot drivers to the latest android drivers which then gave me the sending x to y message when I try to flash anything, but nothing actually happens.
Interestingly enough, I can reboot to bootloader just fine and the Lineage Recovery is still accessible eventhough it shows an:
E: Failed to bind mount /mnt/staging/emulated/media/0 on storage/emulated: No such file or directory
on the bottom which leads me to believe that my device partitions may be corrupted outside of the recovery partition and the phone is bricked. In recovery adb commands can be used and I can reboot to bootloader for example.
When trying to sideload via the "Appy Update" function of the Lineage Recovery, I get an:
Error applying update: 26 (ErrorCode::kDownloadMetadataSignatureMismatch))
everytime. I tried different methods and Roms but nothing worked so far.
Can anyone help me with regards to bypassing signature verification entirely or point me in the direction of another solution?
Thanks for reading, I hope you have a nice day!

I've been reading around a little, it seems like it could be a recovery issue? try the official lineage recovery if you're not already. If you can get fastboot working at all try to reflash the stock rom and go from there.

I had a similar problem. Use a windows computer with the essential drivers (you can download from reddit) and use the official cable

DO NOT use the cable supplied with the Essential phone for data transfer, it is likely to brick your phone. Use a high quality one from a reputable manufacturer!
