Soft brick but with no adb connection on bootloader

[fabulosospucas]

Ok, tired of waiting for the OTA KitKat update for my Nexus 7 2012 tablet, I downloaded the OTA update and sideloaded it with adb. Got a status 7 error and now it's stuck on a bootloop. Thing is, my Windows 8 laptop won't recognize the device anymore (code 43 error on device manager) when on recovery or bootloader. There's even no way to instal google's usb drivers or anything because it says the device malfunctioned. I downloaded the factory image but, obviously, can't sideload it or do anything with it.

Please give me a hand with this, I'm really desperate.

More detail would be nice. What did the bootloop go between? Had you installed any custom recovery like CWM?
Are you still able to access fastboot mode?

Sorry, wasn't sure what you needed. The bootloop esentially goes from recovery to off and then to recovery again. I am able to go to fastboot normally (power and volume down when off).

Wanting to root the device a while ago, I unlocked it and rooted it whitout issues. Since the 4.3 update though, it was a little more difficult to root so having no time to research I just left it at that. That's all that was done to the Nexus 7. No Custom Recovery, no ROM, no nothing. Now, waiting for 3 weeks for KitKat, decided to sideload the OTA update (I did check the version was my device's version) the status 7 error appeared and all hell broke loose with the computer not recognizing the device.

Well, since you still have access to your fastboot menu, there isn't anything to worry about. Once you resolve the driver issue, you must be able to re flash the image.

Duplicate post. Please erase.

Yeah, that's what relaxes me a bit, but I can't seem to fix it for 20 hours straight. I use this for studying.

 

[nobody_nowhere]

Well, I suggest using another computer (a friend's or relatives') or installing a Linux distro like ubuntu. Oses other than Windows usually don't have such problems. I suggest you download something called adb gui which as I recall did a pretty fine job of 're installing the drivers for me.

But then, please do correct me if I'm wrong... I think that you must first use the device on adb and get the drivers installed and then only can you use it by the fastboot interface.

I used Wug nexus root toolkit to install drivers (windows 8.1) there are clear instructions (if you click manual or something similar) how to get drivers to work.

 

[fabulosospucas]

Yeah, actually I did use the toolkit when I was trying to update to KitKat. Thing is, it doesn't work since the bricking occurred.

Yeah, I'll try on another pc, and I'll keep you posted.

Thanks

I'm having a very similar issue. Mine will try and bootup but just stays on the boot animation for as long as I could wait, 10 minutes or more. bootloader is working just fine and I should be able to use fastboot commands to resolve the issue. I'm not able to get to recovery for one reason or another, but it is updated to the latest CWM.

The trouble I am having is the same though. I cannot for the life of me get the drivers to work. I have tried it on one win8 pc, and one win7 pc. I haven't tried any of the toolkits to help with driver installation on the win8 pc yet. I also have another pc that I am going to try also has win8 on it as well. If you can get the drivers installed, please post a reply as to what you did here, and I will do the same, from what I have been able to find you and I aren't the only ones that are having this issue.

If the windows route doesn't work, I have a copy of Ubuntu that will be going on the computer to see if that resolves my issues. Also, may want to try another cord, I have a couple that are charge cords only. Once getting the drivers working it should be a very simple job.

Since you say that you do have ubuntu I suggest using that to fix your issue.... just download and execute the command fastboot from the terminal

Do you think that will be easier? I've not done a whole lot of work with android using linux. I have experience with both separately, but not together. any insight would be fantastic. Have you tried running a linux distro yourself to solve your issue?

It pretty much cancels out any problems with drivers.
It is easy to do.
It takes 5 minutes to boot up and test? Try it for yourself

If I did have any driver issues, the first thing I'd do is reinstall drivers, and if necessary, Windows itself, because I like everything to be working perfectly.

But supposing that that was not an option and I needed my phone or tab real bad, ubuntu would be my first choice. Especially because the concept of installing 'drivers' doesn't exist in ubuntu.

No, that should be fine. As long as you have used terminal before and you know the basics.

I appreciate the advice, I will give it a shot this evening, and let you know if this works. I'm sure that it will.

Alright, so I got SDK up and running on Linux! It was a little bit of a pain, but it installed just fine. Once I got it all installed I was able to see the nexus 7 through fastboot! From there I was able to reinstall the bootloader. Then was able to get to recovery to do an adb push to get a rom of 4.4 on to it. 4.4 installed just fine. All problems are fixed Good suggestions guys!
