If you really erased your boot loader, there is not much help yet.
If you accidentally sticking in apx mode: hold down your power button for about 30 seconds.

I think the tab has a jtag port inside buy a JTAG for like 50$ and you can unbrick

[Q]Brick ?

Hey , i havent touched my N7 forquit a while .. today i tryed to turn it on and found out it is out off power soi plugged it into my charger but when i tried to turn it up i passed the google logo and was stuck at the blackbean logo (when its connected to the charger it show the charging ani but turns off after 5 sec then i need to click the power bottom to see the charging ani again) and when i try to get into fastboot i cant . it just shows me the place where i can select between "start" , "recovery" and "fastboot" but it get stuc on that screen . i cant move anything or just hit "start" cuz it doesnt work either .
So am i bricked ? what can i do ?
i dont understand how that happened since i didnt touch it all week long .. (oh yea and the battery never charges it stays forever on the lowest point of the ani)
Leave it charge for a while without messing with it.
secondly it is not bricked, if it turns on any bit and if it shows anything on the screen it is not bricked.
I don't know why people keep using that word incorrectly, brick means that your device is basically a brick, a paperweight.
And that screen that says recovery etc IS where you fastboot from, that's the bootloader screen.

If you get to the menu that says "recovery" "start" "reboot bootloader" then you are in fastboot mode/bootloader.
Leave it charge a while and see if it works and if not you can flash a factory image or better yet, reflash your recovery and flash a ROM zip

What error do you get when you try flash something by fastboot?
Sent from my Nexus 7 using xda premium
When you are 'stuck' in fastboot, you have a couple ways to go about it... one option and that is to run the N7 toolkit to get the N7 into recovery. From there you can restore your stuff, drop stuff onto your N7 to flash a new rom, etc...
http://forum.xda-developers.com/showthread.php?t=1809195
Basically you run the toolkit like you are going to root it. Then when you get past installing the USB drivers and such, IIRC there was an option to get into recovery.
Ughh, toolkits.

Sounds like you need to fastboot the factory image to the device. Try multiple versions of fastboot. People have been reporting problems and switching to a new version of fastboot has helped.

Sounds like you're in fastboot mode and the above should work. Possibly make a YouTube video to show us the problems.

[Q] Stuck on fastboot, unlocked bootloader, no adb mode

Dear XDA Geniuses,
I have a 16gb Nexus 7 WI-Fi. I was using Nexus 7 toolkit 2.0.0 to try and flash my nexus 7 back to the the stock google rom (option 9 in the toolkit.) It seems as if it wiped out cyanogen mod 10, which i had been using, as well as clockwork recovery. My nexus 7 now boot up with the google logo and the unlocked padlock on the bootom. using the volume rocker i can select the bootloader option and get an android figure with his chest open.
this is the only option i can select. my attempts have been:
1)connect it to computer. Windows 7 and Windows 8 will not recognize it, nor let me access it from the command line.
2. Use nexus 7 toolkit, which DOES recognize it in fastboot mode, to flash a new recovery on there. it says that a command failed, and won't let it write to it.
3) install adb and android sdk tools. my tablet won't show up under devices, and I am not sure if it is still in usb debugging mode. command line will not recognize it as an adb device and will not control tablet.
when i looked at this thread it was dealing with a locked bootloader, while mine is unlocked. it also wanted command line operations from the computer, which does not seem to work for me.
i was attempting to do something like this (laptop mag blog how to hard reset a bricked nexus 7) but without my nexus 7 showing up under devices I am not sure what my options are.
TLDR: Nexus 7 16gb WIFI only boots into boot recovery. Using nexus 7 toolkit to recognize as fastboot. otherwise will not show up on computer. no recovery, no boot image.
Thank you for reading.
I went back and reread the thread on flashing and restoring nexus 7 to stock in this forum, but every command I try returns " command write failed invalid argument ". Using android sdk manager i can get it to recognize the device in fastboot mode. my drivers there seem to be working.
edit: I got all the way to flashing the bootloader, but it returned "no such device or address. "

latest progress can be found at imgur slash TAikq
now it is say data transfer failure - too many links. 146.84 seconds.
it was my cable. the cable mounted it in fastboot mode, but would not allow writing. switched out the cable, and we are up and running again. thanks!
Um.... Glad we could help?

Sticky?
Man, I would love to see this sticky posted, or at least a list of errors and fixes stickied. I have been looking for an answer to the same issue for two days. Finding out it was just a lousy cable really really really pissed me off... I'm glad someone figured it out and actually posted their solution, most of these wind up with nothing.
OMG, I've tried to flash my N7 with a new lollipop 5.1 today and got the same issue as described here http://forum.xda-developers.com/showthread.php?t=2724273 then, after 5 or 6 hours of thinking what is going on, I finally found this very old thread and guess what? Changing this sh***ty cable I was using solved the problem.
Use USB ports on the back of your computer, not the front.

[Q] Nexus 7 won't boot up

Hello everyone,
I have had an issue with my nexus 7 2 days ago and couldn't figure out a way to fix it yet, so I need your help
So basically I have been flashing ROMs on my nexus 7 and everything was great no issues at all, til I accedintaly was in Recovery mode and fomatted sd and system (GOD that was stupid), so after doing so all my ROMs saved on my sd card were deleted so I am not able to flash ROMs anymore. The worest part is that even my preloaded PARANOID ANDROID Rom hasn't been able to boot up my device so it's stuck on Google boot logo.
Hence, I assume if there is a way to push ROMs while the tablet is in Recovery mode that would allow me to flash them again and the problem is sloved. However, I don't know if I am able to do that, I have tried nexus 7 toolkit and Android commander but they require USB debugging to be ON (which i am not sure if it was since last time I had this problem), and they both require the tablet to be tured on I belive in order for them to do thier magic ?? correct me if I am wrong...
Unfortuantely I didn't do Nanadroid backup
I am not able to take the tablet to Google obviousely cause i am rooted so you guys are my only hope
Thanks in advance and really appreiate it if i cab get a fast response.
Just flash the factory image from fastboot.
I use the Nexus 7 Toolkit v3.2.0 by mskip. It is amazing. It's in the development thread. You don't need adb to flash the original image. You only need to get into fastboot mode.--->
Turn off n7. Hold both volume up and down and the power button until you get into the bootloader. Then plug your n7 into USB and then launch the toolkit. Make sure your device is recognized at the top in fastboot mode. You are ready to restore the factory image.

Hi, Tsilva80...
I hate to be the bearer of bad news, but this has all the hallmarks of a corrupted or erased bootloader, in which case your Nexus 7 is probably irretrievably hardbricked.
The lack of the 'white-on-black' Google logo on boot; the lack of the 'white-on-black' battery charging animation when plugged into a wall socket... and the APX entry on Windows device manager, are all symptomatic of a dead, corrupted or erased bootloader.
And without a working bootloader, not only will the device not boot, but you can't even run fastboot commands in order to fastboot flash a Google factory stock image. The bootloader is critical; without it, nothing happens. It's the 'Achilles Heel' of the Nexus 7.
---
APX mode is the default state the Nexus 7 enters into in the absence of a working bootloader, with the expectation that somebody with the necessary technical skills and equipped with an nvFlash tool, will nvFlash a replacement bootloader.
Unfortunately, there is no universal nvFlash tool available for the Nexus 7.
Unless you have, at some point, previously generated unique device dependent 'wheelie blobs' using the flatline procedure (See here and here for more details on this) your only option, is to have the devices motherboard replaced.
Even with the 'wheelie blobs', I haven't read anywhere of anybody successfully using them to revive a hardbricked Nexus 7.
---
Your only glimmer of hope, is that you may have inadvertantly ('deliberately') entered APX mode, by mistake... by pressing VOL-UP (holding) + POWER ON when the device was powered down.
If this is the case, then you **might** be able to break out of APX mode by LONG PRESSING the POWER BUTTON for 15-20 seconds... But this will only work if there is a working bootloader for the device to boot into. If it's erased or somehow corrupted, the Nexus 7 is hardbricked.
See this post, for a list of Nexus 7 button combinations, and more details about entering and exiting APX mode.
---
I really hope you can get your Nexus 7 working again, but based on your post, I can't say I'm optimistic. I suspect you will need a new motherboard.
For what's it's worth... Good Luck.
Rgrds,
Ged.
