Root Nexus failed to flash a new ROM.. now stuck in Recovery

I have a Grouper... rooted running Dirty AOK on 4.2 Android.
Recovery TWRP 2.4.1.0

downloaded ZenonHD v4.4.2 on android 4.4.2
[ROM][Linaro-4.8] XenonHD-4.4.2 Build 7 (23.05.14) - xda-developers
I downloaded it.. and put it on the Nexus.

booted in to recovery
wiped cache and dalvik
flashed the new ROM..
it failed... cant get it to finish the flash/install

so.. now it only boots into recovery.
I tried to mount it to my laptop.. so I can put on a nandroid backup or a new ROM.
but it would fail mounting.

I tried to mount it to a Flashdrive using a cable.
it started "updating Partiton details".. but stuck.
rebooted and connected to my Laptop.
tried to mount.. still "updating Partition details".. for over 1 hr.

so.. I guess what I need.. is how do I get some new ROM files onto this device.. so that I can flash a fix?
thanks.
 
Did you do a full wipe 422 isn't the same as 4.4.2. Sounds like u need to put a working ROM or stock to get out of recovery .
 
if I do a full wipe.. I will loose all files on they internal memory (no SD card). so the new ROM file will be gone.

of course at this point.... it would not hurt to try that.. and see it if will "mount" on to the Laptop. so I can move a new file onto the device.

I just want to see if there are any other suggestions.
 
well... I am not very adapt at adb commands.
I know that I adb on my laptop to root my S3. but that was just following the instructions.

if I knew the commands to push the file over.
can you link me to the right thread???

thanks
 
I would advise updating twrp to the latest version because I do remember there being some flashing issues in the infancy of 4.4.x I think the latest version is 2.7.1.x.

Wiping data in twrp will still leave user data intact. When using the newer versions of twrp, if you click wipe and select custom, you'll notice that there's separate options for wipe data and internal. Wiping internal will wipe everything out, but wiping data will not. Therefore you should wipe data, cache, and dalvik.

To at least get things running, I would download the factory image from google, extract the compressed file and the zip file, and flash the bootloader, system, boot, and cache partitions to your device though fastboot. Do not flash the recovery (since you'll have updated twrp) or the userdata partition (will wipe out all your user data). Once this is done, download them rom and gapps that you want and flash with the updated twrp.
 
As jhawk says, you have to update twrp to flash kitkat.
Don't you have any backup or rom zip on the device you can use to make it boot?
 
nope.. I don't have anything on the device I can use.

that is why I need to "mount" it.
I am going to try a full wipe tonight.. see it will take me back to last working OS..
 
ok guys..

while in recovery.. factory reset it. it did not help.
then I wiped the system. think it should get rid of the bad ROM. that did not help

it can not mount.
and it looks like I don't have SDK or right drivers loaded.

in Device Manger..
my Grouper shows up with and "!" next to it. where can I find the right drivers to load? I have a windows 8 laptop.

and is this the right location for the SDK tool:
Android SDK | Android Developers
 
Hey Dan any joy mate?
Guessing you don't have OTG?

the resets/system wipe you did would never have helped bro. Now. You just have a completely empty tablet lol.
Fixable though.
I was in a similar situation the other day and as everyone knows I hate PCs so was dreading using it.
I don't consider myself a full noob but I flashed a rom for my phone on the tab lol. Basically it wiped the WHORE data partition leaving me with no roms or backups to fall back on.... Really strangely though it didn't wipe system which is usually the first thing a new rom does so I was safe, it booted but had lost root which was easy to fix (off topic but can anyone explains what happened? )
So I'm about to go online and buy an OTG ADAPTER :beer:
Good luck Dan. I'm not a PC guy but one of the genius like Scary or Loony will get you up n running :beer:
 
Hook goes looking for the WHORE data partition thinking he must have missed something. Probably some new XDA mod, and only for Grouper... :rolleyes: ;)

You're actually really lucky you didn't end up with a hard brick in that situation. Different chipsets often have different partition layouts which often result in the rom or kernel flashing over your bootloader.
 
i do have an OTG cable (3 of them).

I tried to "mount" a Flashdrive to it.
this used to work in the past.

but since the failed flash of the new ROM.. it will not mount anything... PC or OTC w/flashdrive. (flashdrive was tested and works fine)

is there another way to connect the Device to a Flashdrive.. using an OTG cable from Recovery mode?

Just a stab in the dark, I haven't seen any mention of Wugs, or Nexus 7 Toolkit in this thread so far.

And I know in those, (haven't used) side-loading as possible method to push also is possible.

And, for the sake of additional idea's, Galaxy2, (Yea I know it's not a tablet) is responsive to ODIN, through USB, when everything else won't work on that device. Maybe it would help to try, before giving up hope?

One more,our own Scary Alien, developed Android Root Toolkit available free on the Playstore, can work it's own wonders restoring root, and keeping root for the Nexus7, when all hope was lost for me, (different problem), still good to know.

As far as toolkits go, I do believe that the Nexus specific toolkits were replaced with the Android Unified Toolkit. It might be worth a go to push the latest TWRP to your phone, Dan.

Replace might be too strong a word, at least with reference to WUG's toolkit, which I rally do feel is best for pure Nexus devices. Haven't tried AUT, and I'm sure it is fine and covers a much wider array of devices.

I was only referring to skipsoft's Nexus Toolkit, not all of them (including WUG's which a different animal). Sorry for the confusion.

I know too well bro thought it was a gonner

Just find it weird that the script didn't fomat system but did data lol.
Oh well, lesson learned. Don't use one device to download a rom, send it to the other and forget to wipe the original :thumbup:
