Updated TWRP and now not booting

I updated TWRP today to 2.3.0.0 from within GooManager then rebooted into recovery and fixed my permission. It was done unusually fast and when I rebooted, it would get stuck on the booting screen. When I tried to boot into recovery by pressing power and both volume buttons, it would get stuck on the google logo.
Please advise.
Any other way I can fix this or somehow restore from a backup?

A lot of users are having issues with cwm and twrp not booting with new boot loader. You can revert back to old version or some have had success by deleting "recovery-from-boot." file. You can look at http://forum.xda-developers.com/showthread.php?t=1779092 I'm going to wait patiently for a twrp update that should resolve the issue.

Thank you very much!
I'm sorry but I'm not too much of an expert on Android. AFAIK Recovery mode is the only way I know to do some low system stuff. If I can't boot into recovery, how else can I do anything to fix this?
How can I revert back to old version?
I know you linked the other thread but there are 33 pages I was hoping you would have a short answer hehe thanks.

Is it constantly rebooting at the google screen or just stuck?

If I try to boot into system, it's stuck on boot animation.
If I try to boot into recovery manually (power + volume buttons then select recovery) it would get stuck on Google. It doesn't loop.

I see that you posted over on the twrp thread, hopefully those guys can help you. I am assuming that you have updated to 4.1.2? If you're really stuck maybe try a tool kit like wugs or n7 toolkit? Sorry but SDK isn't one of my strong points either

You can reflash recovery from fastboot. If you've updated to 4.1.2 you might be experiencing same issue as many of us - being unable to boot to recovery. If that is the case, flash bootloader 3.34 from the JRO03D factory image as well.

From what I understand, in order to reflash recovery from fastboot would require me to get the file to the device. However, right now I can't seem to get access at all as it never boots up whether into system or recovery. Are there any other ways to get files onto there?

OK this is weird. I tried rebooting into recovery again and it worked! I then rebooted into system and that worked too! This is so strange because I didn't do anything different. I guess it just took 20+ tries... I am not rebooting in a while... lol

which sounds like you were able to get to fastboot mode (power + vol buttons) - your N7 should look like this. From there you can issue fastboot commands to the device to flash recovery. kerne, and bootloader to name a few.

Actually I spoke too soon.
I can boot into recovery TWRP 2.3 with USB plugged in, but still can't boot into system.
Is it possible for me to downgrade to TWRP 2.2 from within TWRP? I kind of doubt it but am pretty desperate at the moment lol.
Yes, I can get into fastboot, but I'm not sure how to do anything besides pressing volume up or down to start, recovery, fastboot or shut down.

If you can get in to fastboot you are in good shape. :good:
You'll need the fastboot program (and the driver if on Windows) on your computer in order to issue commands. This guide can direct you on how to get that set up.

Fortunately I was able to wipe everything while I was in recovery and restore from my most recent backup and now it's working fine. At the very least it's allowing me to boot into system
OK I'm really not rebooting for a while lol

I installed twrp a few weeks ago through GooManager and made a backup. When the 4.1.2 update came out, I downloaded it manually with the intent on flashing it via cu custom recovery, but low and behold twrp wasn't working at all. Even with my device plugged into my Win 7 pc... nothing but the exclamation point droid.
I was able to install an updated version of twrp and get everything sorted out, but now I don't have a lot of faith in it, and am booting into recovery at least once a day to make sure it's still working. I never had any problems with cwm.

Twrp has been updated if you're still having issues.

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

Its a bit complicated. Also how do I get the boot.img to my computer from my nexus 7 because when I connected the Nexus 7 folder is not under "My Computer"

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.

[Q] Tried Rooting Nexus 4 following the guide, but now it's not working

I followed the guide from this forum on how to root a Nexus 4, but in the process I think I've broken my phone.
I first tried flashing AOKP and it's GApps, the phone booted fine, and I was able to get to the wifi set up screen, however, I couldn't get wifi to turn on.
So I tried to flash Paranoid Android and it's GApps. But now the phone won't get past the boot screen that comes after the google logo.
I've asked around and Googled around for a solution, but I can't find anything. I've been trying to get this fixed since yesterday.
Can anyone please help me? I just want to be able to use my phone again.

How are you flashing? Adb or a Toolkit?
Edit:: How long did you wait? Sometimes it might take awhile, especially with PA.

Just put your phone in fastboot mode and flash factory image.

Okay now I have a new problem. I turned the phone off, booted back on and tried entering recovery mode, but now I have an image of an android with a red ! mark.
I was just about to try flashing an older version of the stock.

That's normal for stock recovery, you won't be able to sort your phone from there, stay in fastboot mode. You can use a toolkit to flash back to stock from there if you need it more noob friendly. Otherwise you can use the flash-all.bat script in the factory images.

You mean the android is on it's back, press the volu+ button, press power, and that will take you into the stock recovery.

Oh god thank you.
Okay. I'm trying to reinstall Paranoid Android now. I did the sideboot via ADB.
I couldn't seem to get the stock version of android on it though. I made sure to open the tar file and tried to move the .zip "image-occam-jdq39.zip" onto the phone, but it wouldn't accept it. So I'm trying Paranoid android again.
Edit: I got it booted. But now wifi won't work. Neither the speakers.

It didn't work because that's not how you flash a factory image. You need to be in fastboot mode and flash it from a PC using fastboot program. You used fastboot when you unlocked your bootloaders in the first place. You have stock recovery so you can't flash a custom rom, which is why your adb sideload of PA didn't work.
Like I said before you can use the flash-all.bat in the factory image. It runs the following commands which you can also use manually.
fastboot flash bootloader [path-to-bootloader.img]
fastboot flash radio [path-to-radio.img]
fastboot -w update [path-to-system-image.zip]
If that's too difficult use a nexus 4 toolkit to download and flash a factory image automatically. With your phone in fastboot mode, not recovery.
The above will fix your phone, trying to flash custom roms and system image zip in recovery mode will not.

Doing so now. If I had known about this tool before, I probably would have been done with this a lot sooner.
Currently flashing stock and unrooting.

The toolkit is most certainly the way to go. No mess, perfect every time for me.

[Q] Nexus 7 stuck at the google logo

Hello,
I've got a problem. On monday my Nexus 7 2012 (with lastest stock Android) froze and I had to reboot it. But then it got in a bootloop where it would boot to the boot-animation (the four moving dots) and then restart after half a minute. Then I went into the bootloader to switch it off. When I switched in back on it just got stuck at the google logo.
I tried to reflash the stock rom, but I haven't unlocked the bootloader yet and everytime I try to do unlock it, it fails with "unknown error code".
At first I used Wug's Toolkit. When that didn't work I used cmd, but that doesn't work either.
I would really appreciate some ideas to solve that

You dont have to unlock the bootloader to flash factory images.
You can flash it with fastboot or a toolkit.

Did you try to get into recovery?
Maybe you can wipe some thing like cache, dalvik cache and system,
And then install the firmware again.
I once installed a firmware without properly wiping and also got stuck in thjis animation logo.
After wiping in recovery and re-flashing the firmware it worked again.

I dont't have any custom recovery installed. When I am trying to access the stock recovery mode via the bootloader then I get to the Google logo and "booting failed" is written in the upper left corner.
My guess is that the emmc is broken

Google search android factory images, download the appropriate one for your device
Then extract contents and double click the flashall.bat
If this fails then chances are your emmc has been severely corrupted, I've seen a few get to that point with the booting failed and its 50/50 if they resurrect their device
Best of luck
(Oh and don't use toolkits)

No Bootloader

Hey, I flashed the new DP4. Now I wanted to revert back to MM but the phone doesn't boot up twrp. It just hangs at the twrp splash screen. Fastboot wont work either. REbooting into bootloader doesn't work. Going for it reverts the phone back to the screen where you see an android laying on its back. Evrything enabled except for download mode. Even clicking on starts doesnt boot up andorid n. Android n only boots up when click either on factory or bp tools?? Typing adb devices via adb only show list of attached devices, typing fastboot devices results into nothing
Any ideas how to get back to twrp.

When you say bootloader doesn't work; what doesn't work about it? Your bootloader should look like this http://www.androidcentral.com/sites...exus-6P_bootloader-unlock-1.jpg?itok=aDeXgpNz
From there you should be able to flash the factory image and get a usable phone back.

Yeah if your bootloader didn't work you would have an actual brick(meaning no turning on and nothing on screen). That's the one thing your phone can't function without. Unplug your phone from PC and then hold the button combo to boot bootloader. Then flash a factory image minus the -w command and then flash recovery.

It's hard for me to suggest anything because you haven't given any background on the situation. Here's an idea though:
Flash TWRP recovery to the device.
Enter TWRP, enter the wipe menu, select advanced wipe, tick the system, data, cache, and dalvik cache boxes, and swipe to wipe.
Boot back into the bootloader and flash the factory images (minus the userdata.img).
Boot the phone up.
If you need instructions for any of this look at my guide:
