How are you certain your recovery is gone? You might just be stuck in bootloop. Your best bet is to use toolkit to get you into recovery. Whether Twrp or CWM. From there youcan flash a new kernel and see if it fixes it or use it to restore a backup.
I had similar issue where it was stuck on boot screen. I ccouldn't enter recovery normally. Only way was hooking it up to a pc. Then using a toolkit to make the tablet go into recovery. Then from there, I could use recovery on tablet itself and restore a backup. From there I was good again. Problem solved for me.
Try one of the other toolkits, like Sambra one. Make sure drivers properly installed though.

It's an easy fix, just use wug's toolkit and flash the stock Nexus 7 image. It will be like brand new. I don't think you had a very major problem at all to begin with just a minor bootloop, but this far along I'd restore it to stock and start fresh.

Try locking the boot loader and unlocking it again, then rooting flashing and so on..
Sent from my Nexus 7 using xda app-developers app
now i got it to the point where it goes back to sending system but it still stops, if i do relock the bootloader how would i unlock it? and if i did root it it wouldnt make a difference cause i cant get back to an os
I seem to have messed up the process. I successfully unlocked and rooted my Nexus 7 but during wipe process using JROM flasher something didn't go right and now I'm stuck at the google logo screen forever. I can boot into fast recovery mode but that's about it. I can't do anything.
I've had this done before on my nexus phone but it seems I managed to f it up this time.
I thought I had a rom zip file copied on to the Nexus 7 but it doesn't show in the menu. Now I'm stuck at the logo screen not having access to any roms to install. How do I reset all of this to factory? I've already checked most of the threads regarding this and haven't been able to find a solution yet.

before you do anything, use your recovery to see if the rom zip is located in /data/media/0/. if its there, flash it from that location.
Are you able to boot into recovery?
If yes, it could be as simple as plugging your tablet into the computer and mounting the usb, drag and drop the rom, and flash it without using a toolkit (only recovery). I'm not familiar with jrom flasher, but i will say the more variables there are, the more chance of a problem.
If no, you're best off running the stock factory image through your computer, found here: https://developers.google.com/android/nexus/images#nakasi. I had your problem at one point, and could not even boot into recovery. After trying to install cwm through adb (which failed), and a number of toolkits, the factory image was what brought my nexus back to life.
I remember reading that sometimes a wipe can delete your recovery as well as your system (and whatever else you have on your n7), although i dont know if that was ever fixed, as i got my tab replaced a month or two ago and havent rooted it again yet. There was some type of command or .zip or something that should be used to keep recovery after wipes. When i expirienced problems such as yours, it was also from a bad wipe from a toolkit. Using just the recovery afterwards, i never expirienced any issues, even without the recovery fix.
I would definitely try simms suggestion first if you can access recovery. If that fails, try one of the above processes.
PS, even if you can access recovery, if at this point you just want to go completely stock, the factory image will work regardless.
cheers
Thanks for the help guys, I've been struggling for the past 3~4 hours but I found a solution.
What I did was use JROMFlasher and upload a rom zip to the sdcard directly and go from there.

hello all. I really need some help. I let my friend play around with my nexus 7 and he got into the TWRP and accidentally wiped everything off my nexus including the OS so now when i boot it just hangs on the google splash screen. I can get into fastboot mode and the team win bootloader screen but thats it. When i connect to my computer it is not recognized so i cant drag and drop a new boot image. I would just like to have my nexus back to factory unrooted bone stock
Please help me out. I'm new to the android scene and freaked out that i have a bricked device.
Thanks in advance!

First of all, stay calm! :good:
If you are able to reach fastboot mode, nothing of value is lost (beside your personal data). You can just follow this guide.
At the end, your Nexus will be as fine as before. And don't forget to threaten your friend not to do such things again if he doesn't understand how to repair it.
P.S.: You don't have to unlock (flashing step 2) and re-lock (flashing step 5) your Nexus as you may have unlocked it before (according to information about installed TWRP). And be sure to use the nakasig/Tilapia image for flashing.

Thanks I'll try that guide out tonight after work.
How it happened was I received the OTA update for 4.2.2, but didn't update. So when I let him use the tablet he thought he was being nice by updating for me and when the nexus reset it kicked into TWRP which he thought he f*ucked up and decided to "wipe" what he did.
Odp: [Q] Need help. OS was wiped using TWRP v2.3.2.1

That's the reason why I don't let anyone (even my best friends) to do anything on my phone without me looking what they are doing ATM. You should have done the same.
All your data you've had on your phone/tablet is permanently gone, all you have to do now is to restore your os from a backup (if you have made backup before) or flash other ROM and you are good to go
For the future knowledge - if you can access any recovery mode it's almost impossible that your phone is bricked. If you can only enter fastboot there is like one percent chance of this that your phone / tablet is bricked.

You could flash a recovery with fastboot < fastboot flash recovery recovery.img > (just necessary if TWRP got wiped during the update) and then push a ROM with adb.
This method wouldn't delete your SD card.
How do you know that he just didn't wipe system? It's possible that he didn't, so all you may need to do is flash the system image. If you have driver issues while in fastboot, I recommend the official Asus drivers.

Hi all,
As the title suggests, I have a bricked phone.
A little background, I rooted the phone then installed CWM. After that I installed CM10.2 but didn't care for it so decided to use Scotts stock rooted rom. To install that you have to have TWRP so installed that using Loki/adb. TWRP booted fine but when I went to do a wipe it hung at formatting cache. I rebooted and tried it again with the same results. I decided to try to install the rom anyway (dumb I know) and now all I have is a blank screen. No LG logo or anything. When I connect it to my pc windows recognizes like 10 different drives. I can't get it into download mode or recovery.
Am I screwed and need to see if ATT will replace it or is there a work around for this?
Thanks!
Wiping takes a long time. let it run and finish... could take 10 minutes or more.
how are you trying to get into recovery?

Yeah I let it run for about 15 minutes which is considerably longer than it usually takes on any other phone I've done (many).
Tring to get to recovery using the power key method.
The thing is that it never gets to the LG logo. Nothing shows up on sceen at all but it is on.

I'm in the same boat except I never installed a custom recovery or rom. Have you tried fastboot?
If it boots directly to a black screen (no lg splash), i'm sure ATT won't have any issues taking it back as they won't be able to see that it's rooted.
http://www.lg-phones.org/how-to-flash-unbrick-lg-g2-back-to-stock.html Here's a way to unbrick g2
Yeah I tried the flash tool too. No luck as I couldn't get into download or recovery.
I wound up taking it back to ATT and they gave me a new one no questions asked.

Ok guys, I'm in deep trouble here. Kind of extremely desperate.
Please bare with my wall of text!
So I had just backed up my ROM, copied over the previous nandroid over to my computer and deleted it to make space for the new one. Made the new one, copied over the kernel I wanted to flash. Rebooted into recovery and simply flashed the kernel. That's where the screw-up started.
Wiped my cache and rebooted to a flashing purple and blue screen. Turned my phone off immediately and went to restore the backup I had just made. Not even midway through, I got "error while restoring /system". Nandroid is apparently no good?!
Now, I don't have anything on my SD to flash, not even a clean CM, another backup, nothing. I can only boot to recovery, if I try to reboot, I just get the google logo, then it goes off and back on, and so on. If I connect the phone to my PC, it obviously isn't detecting it.
I need a way to push or copy another nandroid backup or just a ROM over to my SD to flash something! I can't have bricked my phone!
Not too familiar with adb commands, haven't used them in ages!
I appreciate any help you can give me!!

If you're talking about this one, reading the thread right now. About to download the windows version and try to flash stock and unroot, then root again.

As far as losing root, you shouldn't lose it, and there's no reason to believe that you might have already lost it, but if you are planning on flashing stock and unrooting then it wouldn't matter anyway.

I'm stuck!!!
I tried flashing stock and unrooting, but I had issues with what it said could be either my drives not being installed, or my USB Debugging not being enabled. I don't think I ever enabled USB debugging after this last time I flashed CM. I tried going through full driver installation, but I still hit the same wall with USB debugging not being enabled!!
What should/can I do?
Boot into recovery and connect your USB cable on it. Download an ADB standalone and place the files you want to transfer there, open it and type:
adb push (local of the rom/kernel/wharever) (path to sd/internal storage). it would be something like that
adb push rom.zip /sdcard/0/
this will transfer the file to the root of the internal storage.

Just a thought, have you considered using TWRP? Are you sure it was actually a bootloop and not a boot that is just taking a little longer than usual to finish?

I waited for over 5 minutes, turned it off, and tried booting it up. After another 3 minutes of nothing, I gave up.
Tried sideloading an old backup but wasn't able to sideload anymore..
Currently trying to do the driver things in the toolkit..
I may have screwed this up even more.
While doing Step 1, I again couldn't do the whole USB Debugging enable/disable, so I just went and did everything else that I could. Step 2 installed, Step 3 couldn't recognize my phone, just went back to Google bootloop.
I don't think I can even try sideloading stuff anymore.

EDIT:
Ok, sideloading CM again. Currently at 70%. I'll keep you guys posted.
Sorry to post 4 times in a row, but still stuck in the CM bootloop.
Is there anything better I should try sideloading? Maybe a factory image?
Something that would completely restore everything?
Sorry to post 5 (FIVE) times in a row!
FIXED IT! **** YES! I was running out of time too, have to wake up in four hours for work, hahahah.
I really don't know what happened this time. Tried running the Flash Stock + Unroot again, and it went through!
Going to enjoy stock for a while, this scared me way more than my previous adventures with rooting have, and I'm not entirely (but mostly) new to this!
Thank you so much for your help man, couldn't have done it without some support. Really feel indebt to the guy that made the toolkit, though. Thanks all around!
