Root Nexus 7 Bricked !!Bootloader Erased Help!!!!

Do you have one of the toolkits installed on your PC?

Unless one of the toolkits can flash a bootloader without fastboot, the OP is in a catch 22. He needs to flash a bootloader but AFAIK you need fastboot (and thus a bootloader) in order to flash it. If the OP can boot into the system, maybe there's a way to write it from there. I'm not sure though

i bricked my n7 and gnex more than once all i had to do was plug and unplug my charger and refresh the menu on my all-in-one toolkit till it showed up then i selected the option to reboot- then reboot into cwm... maybe it will help you. maybe not

Unfortunately, this won't work in this case. Without a bootloader, the device essentially doesn't know how to boot anything. That means it can't boot into fastboot, recovery, or system. Giving it a command through the terminal or a toolkit to boot into something won't help because then device won't know how to do so.

thats correct... so there is a way to fix it. and it is with nvflash. BUT, it just work for the Asus Transformer... so im waiting for the nexus 7 app...

The thought had come up, since I do also have an Asus transformer infinity, and another staff member suggested the same thing. However as you stated, nvflash isn't possible at this time. Maybe down the road it would be possible though if you don't RMA the tab first.

Cmon people these things aren't built with the bootloader on them.

Think man, think!

:D

When you try the vol down + power to get to bootloader does the screen show anything?

I tried this on my N7 16gb and here is what happened: Booted to fastboot, issued "fastboot erase bootloader", successful no other selections, power + vol up did nothing. Powered down, used vol down + power, got into bootloader screen showing the <START> option only. Fastboot devices did see my N7, issued fastboot reboot-bootloader and came back with all the options. Tried this again, same results. Then I booted to recovery, reflashed my bootloader zip file with CWM and the bootloader was normal with the hardware buttons again.

Can't say why this worked, but went through the whole process twice and it did.

I don't recommend anyone try this though, maybe I just got lucky or something?

EDIT: some other info. When bootloader had the <START> option only, pressing power on that option DID boot the device, so maybe my bootloader wasn't completed erased? Also, I'm on JB 4.1.2 but I'm using grouper bootloader 4.1.3 from the JB 4.2 build.

it did not work for me.... my computer does not recognize the device. and therefore I can not use any tool ... following a tutorial i install some drivers and the computer recognized it as APX device

How on earth did you escape that. are you sure you did enter the command "fastboot erase bootloader" if so could you explain with more detail how you got out of that with a very clear step by step procedure if possible because so far I have never seen such a story (unless they backed up with NVflash) and also what is CWM did you have that installed already on the bootloader before the incident because it is said to be impossible for the bootloader to show anything if it is deleted. you may have done the world a huge favor so I would keep an eye on this experiment

thanks for taking the risk
