Tried going back to Stock - Nexus 7 Q&A, Help & Troubleshooting

i unrooted my nexus 7 and now it is stuck at boot loop i just stuck at the boot logo.. the unooting method had to be success cause it said and it re booted it just stuck at boot logo

Ok so Power off your device, or whilst its rebooting hold the Volume Down button.
You should get back to your BootLoader
Plug it into PC and then do fastboot devices.
Your device should be listed.
I would re-unlock your bootloader.
Then Download TWRP - http://techerrata.com/file/twrp2/grouper/openrecovery-twrp-2.6.3.0-grouper.img
Put that in your Fastboot folder on your PC and type: fastboot flash boot openrecovery-twrp-2.6.3.0-grouper.img
That should flash TWRP. Then push volume up in your bootloader menu, until you see "Recovery".
Open the Recovery and TWRP should load.
Then go to : https://developers.google.com/android/nexus/images#nakasi
Download the correct stock image depending on your version you were at before you tried doing what you did.
Then, depending on the version you downloaded do this (I'll use the 4.2.2 one as example).
On TWRP, go to "Advanced"
Then you should see "Sideload"
Choose sideload and swipe accross, it should now say something like "Waiting for sideload".
Go back to your PC And open another CMD as you would for fastboot.
Type adb sideload nameofyourdownloadedimage.img
Wait for sideload and whalla
(I may have missed something, if so when you get stuck let me know and I'll help further".

Are you stuck at the "Google" splash or the "X" bootanimation?

Permarooted s-off still get no CWM recovery mode!?

I am rooted with s-off running on a ATT simcard but still can't boot in CWM recovery. In rom manager it says: current recovery Clockworkmode 3.0.2.4
Whenever I attempt to boot into recovery the MT4G comes up it reboots and it comes up agains and boots regularly. Any thoughts?
I followed all the instructions in this thread and am at the 85.xxx bootloader

I am bone stock other since I've not be able to get into recovery mode. Would a factory reset help?
Do it manually. Go to the bootloader and load recovery from there, or use adb and type adb reboot recovery.
adb does the same thing it attempts to get into recovery then goes blank and reboots regular and same thing with hboot.
Do you have fastboot on?
Nope. Fastboot is off. I can't even factory reset the phone. It just reboots like with everything else

most likely it feels as if the recovery image didn't take.
Code:
adb reboot bootloader
from there select "recovery" and see what boot loader you are using. If you have the engineering screen manually flash it.

1. Download CWR3. - link supplied above
2. Save to your Android SDK tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools) folder and rename to recovery.img
3. Turn off your phone.
4. Hold the volume down button + power until you boot to a white screen.
5. Use the volume rocker to select FASTBOOT then press the power button to select it.
6. Connect your phone.
7. Open up a windows command prompt and navigate to your sdk tools or platform tools folder. tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools)
8. Type
Code:
FASTBOOT DEVICES
to make sure your computer "sees" your phone and is ready to flash the recovery. You should get a serial number and then the word fastboot as the output.
9. Type
Code:
fastboot flash recovery recovery.img
and press enter. Give it a minute to do it's thing. You should get a message that says writing recovery and success.
10. Unplug your phone and use the volume rocker to select BOOTLOADER and then again to select RECOVERY and you should be booted into the orange menu of Clockwork Recovery 3

It says fastboot isn't a recognized command when I type FASTBOOT DEVICES
also for the bootloader part. It loads real quick and it says something about no image or wrong image in the lines of code that loads on the screen then disappears
Are you using Linux? If so, cd to platform-tools and use ./fastboot instead of fastboot. Otherwise try updating adb and see if it works. Also, the random text is the phone searching for PD15IMG or another restore image. Disregard that, unless you want to flash the stock unrooted image.

TWRP 2.1 | fff 1.4a problem

Rom: Stock
Rooted with KFU 0.9.5
TWRP 2.1
fff 1.4a
The problem I'm having is that when I boot my KF up it goes to fff. I get 3 options to boot from (this is whenever I power down the KF). When I choose to boot to recovery, the power light turns orange for two secs and then it boots; but back to the fff screen. I did this about four times in a row and it still boots back to the ffa screen.
If I choose ~normal boot~, It boots up fine. When I try to use KFU to boot to recovery or fast boot, it says that it is waiting for device. I tried this several times but no luck.
I want to get into recovery. That's my goal. I'm guessing that the KF is not booting in fastboot for it to go into recovery. I tried to reinstall TWRP 2.1 with KFU and it gets to the point where it's waiting for the device and nothing happens.
I'm not very advanced in this stuff. Please be patient with me. Thank you for all your help.
what command are you using to install recovery?
ok
download twrp 2.1.1.img onto pc
turn off kindle (20 second hold) with the usb cable unplugged from the kindle
open terminal where you have fastboot located.
type the following:
fastboot flash recovery </enter/path/to/recovery.img/here>
press enter
you should see waiting for device
then plug in your usb to kindle
this should power up the kindle and fastboot flash a new recovery.
then type
fastboot reboot
note:
(there is a space between recovery & /
i also find it easier to put a space after "recovery" then drag & drop recovery.img into terminal)
ok...
I did everything you said and the cmd console was still <waiting for device> after I plugged in the KF.
I checked in device manager and that's ok for the adb (it says: android composite adb interface).
Still looking to get into twrp recovery.

There's probably something wrong in KFU's process. Could you at least show us its log or a screenshot?
reflash twrp using smirkit. than try to get into recovery again
Sent from my Galaxy Nexus using xda premium
if its waiting for device your pc is issuing fastboot command. so as you say its your kindle.
one of the above methods should work.
imho smikis's smirkit is nice to use
edit: can you copy and paste your commands after you try to flash new recovery

Trouble flashing 5.0.0! Help needed!!!

Need help here!
My Nexus 10 was with stock 4.4.4, rooted with TWRP. I decided to flash the factory image files by removing the -w in flash-all.sh. However it ended up with being stuck with the rotating balls. After about 45 minutes, I decided to go to the fastboot mode (pwr+both volumes), then select recovery (I planned to do factory reset and clear cache). After trying to reboot into recovery mode (pwr + one volume button), it now shows an open bootloader with following message below the bootloader (the bootloader seems still unlocked):
Dowloading...
Do not turn off target!!
What does it mean? What is it exactly downloading? And what should I do? Should I lock the bootloader? Also it does not respond now if I push the volume buttons. It's not recognized on my Mac with the with the following command:
fastboot devices
I also notice the following line:
Reboot Mode Flag: NONE
Now I just booted into recovery, but it shows the bootloader with the exclamation mark! After a few minutes, it automatically switched to the never-ending rotating balls. What can I do?
When you get the Downloading...message you're in the Recovery screen. Don't worry about the message. Press vol up and power to get into the recovery menu - there you can wipe cache and system. As you're in recovery, Fastboot devices will not recognise your tablet, only adb commands.
If I was you and this didn't work, I'd just reboot into fastboot and flash the image files manually. You'll lose root, data and twrp but these can easily be gotten back through fastboot.

Flashed the wrong recovery

I followed this guide to root my Nexus 10, did the oem unlock, downloaded the linked version of TWRP and flashed it via fastboot, now it won't boot and I can't get into recovery mode, because the version of TWRP was apparently meant for the Nexus 7 aka Flo.
It starts booting normally, but the boot animation just seems to go on forever, I waited around 30 minutes for it to finish but it didn't.
I can get into fastboot mode, but can't change the boot option and I haven't been able to flash anything (doesn't show up with fastboot devices), Windows recognizes the device as "Gadget Serial".
Is there anything I can do?

Install the ADB drivers on your PC, and then use the command prompt to boot into recovery : adb reboot recovery
http://lifehacker.com/the-most-useful-things-you-can-do-with-adb-and-fastboot-1590337225
What? I can't boot into recovery mode because I flashed a recovery for the Nexus 7. And I can't use ADB because I can't boot into Android either.
Use WugFresh Nexus Root Toolkit. It's worked for me on tablets that could not get past the bootloader on their own.
http://www.wugfresh.com/nrt/
1) Press power + volup + voldown and enter bootloader
2) Flash recovery with command:
fastboot flash recovery recovery.img
done

Semi-bricked??

Weird: I was just using it normally, it switched off and now it stays stuck on the Google logo; when entering recovery mode, I get TWRP"s splash screen and it stays there, so I cannot even recover.
Suggestions please??
Note 1: I'm pretty bad with this kind of stuff, need step-by-step instructions.
Note 2: rom is AOSP 7.1.2 but I guess is irrelevant, as even TWRP does not load.
Thanks in advance!!
Can you fastboot boot the TWRP recovery?
Hmmm dont know exactly what that means sorry; I mean I havent tried connecting it to the laptop and using thr ADB toolkit, but I can reset via Power+VolDown to the bootloader menu (? the android layind down and giving the option to StartSystem/ SwitchOff/ Restart/ RecoveryMode), and choosing RecoveyMode it tries to launch TWRP (it even shows the logo) but stays there on the splashscreen, doesn't quite manage to give me the TWRP menus
Someone?

let's see... I set in recovery mode, connect to the PC (does not recognise it), and with "fastboot boot twrp.img" it just sends/writes the file, the tab shows the Google logo with open lock, and then tries to launch Twrp, but as before, it just get stuck in the splashscreen "TeamWin Recovery Project 3.3.1.0" , so just the same.
Command "fastboot flash boot twrp.img" the same
Command "fastboot flash recovery twrp.img" the same
Command "adb devices" returns the list empty
Command "adb reboot recovery" returns "error: no devices / emulators found"
Command "fastboot oem unlock" returns "(bootloader) bootloader is already unlocked"
I tried running a tool called FirstAid (https://forum.xda-developers.com/devdb/project/dl/?id=16684) but does nothing for me
I'm lost, please help
Video and photos of the issue (device, not adb)
video: https://photos.app.goo.gl/GrFrmQhbyQeHVFZN7
Well, looking at your video it seems that there is no bootable ROM installed and also the recovery (for what ever reason) has some issues to start.
The fact, that you are able to boot into bootloader shows that at least it's not completely bricked ... but there's still the chance that the flash memory has some issues.
I would connect the device via usb with a PC and try to do a
fastboot boot <twrp-3.3.1-grouper.img>
to whether in that case the recovery is booting.
If this is successful, the next step would be re-flashing the recovery into the recovery partition and booing into recovery mode from the bootloader.
If this is successful, too, wiping and flashing a new ROM would be the last step.
