As long as bootloader is viable, you should be fine.
Download the FULL system image from Google:
https://developers.google.com/android/nexus/images#nakasi
Make sure you chose nakasi for WiFi or nakasig for 3G tablet, depending on the one you own.
Download file, extract tgz and extract zip inside of that.
Make sure you have adb/fastboot installed and in your path and that your tablet is connected and recognized. Boot into bootloader mode (which needs to be unlocked). Then do a full flash (you can omit the -w option to prevent the flash from wiping sdcard).
This will restore your device OS back to stock.
Depending on what you did, which you didn't really explain, there is probably a quicker/easier option. But without more info, the only advice I can give you is what I did, which should work fine for all circumstances.

Sticky post above this one is the solution..
It seems like you from your post you used a tool kit and something went wrong or you missed a step. Follow one of the following guides.
I recommend the first one..
Manual adb/fastboot
http://forum.xda-developers.com/showthread.php?t=1907796
Took Kits Automated flashing/ rom install ..
This one is a Windows interface.
......... http://forum.xda-developers.com/showthread.php?t=1766475..........
CMD Interface.
...............http://forum.xda-developers.com/showthread.php?t=1809195..........
I recommend the Manual method But only after reading post in all the threads. This will help you get a better understanding of Android..
Good Luck... the post above mine is also correct if you already have a adb environmental set up

Thank you
Thank you all for your advise
The nexus is once again alive
Have a very happy holiday season

no, you have to get to bootloader, I figured that out, now I'm sutck on "archive does not contain boot.sig" etc..

Hi
I got the same issue....
I can access the fastboot mode and the recovery mode, but not the bootloader. I go back on fastboot mode if I try to load bootloader...
I want to reinstall but windows doesn't recognize my n7 :/ so I'm stuck at this point :/

[Q] Xoom files doesnt change

Hello guys,
i got a serious and frustrating problem here.
A few days ago my xoom was stuck on the M screen, so I used a thread in the forum and recovered it.
It solved myh problem back then, but since I had 3.2 before this and the solution injected me with Android 3.01 my problems started to show themselves.
the first one is that
<b> Through Fastboot, RecoveryMod, ADB </b> and any other way you can Imagine to install a new ROM or even remove or create a file,
All of them show success message but when I check them out I see no changes.
i tried fastboot and Recovery to install nearly every ROM,Recovery and bootimage in this site but so far it was wild goose chase.
so I want to ask if I'm doing anything wrong or if you need any more information here, but please help me with this
wow I cant believe it, All these masterminds here and no answer to my distress signal??
Guys I am so in trouble and this is the only place I hoped to get answered.
I can provide you with more info if you need, but please dont say I'm on my own here.
all these years this forum was the last hope for me.
i know I'll get my answer here one day
You are not being very clear about what you have done,, but I'm assuming that you reinstalled the stock image that got you back to HC 3.01. Can you see if you are able to get OTA updates to get you back to at least 3.1, or 3.2 if possible?
If that's my problem forgive me please, Ive written that post in 3:00AM
for the sake of clearity I should add some info:
1. I even tried stock ROMs but you see I cant even flash them (Not from Recovery nor Fastboot) the steps seem successful : it opens the package,it installs them and it says everything was a success. But when I restart the device I see nothing has changed.
2. OTA updates are the same, they keep downloading and when the sysem reboots to recovery to install them it cant find them.
3. You dont believe it if I say even files and programs that I remove from device by my hand(Android OS) are back after the first restart.
And you see it's dark magic! everything from a file to a partition are back by one reboot. I dont know what should I call it but I havent seen anything like it on the whole Internet.
So seems like I should make a competition for the xda experts here
Can you publish it so all of them can see it?

That would be relief to know this could be solvable.
I will look more too.
As for your post I must say:
1. I plug the Xoom to the PC using the included cable
2. I start the xoom and start fastboot
3. on the PC system has the drivers and completely knows it
4. I start with SDK:
I. Fastboot oem unlock (Completing onscreen instructions and reboot device)
II. Fastboot mode again I use Fastboot flash boot boot.img
III. Continuing with Recovery,System
IV. Rebooting the device anything is the same.
My ROM is unchanged by the process and keeeeeeeeps giving the damn error of System process error please submit
5. And with ClockworkrecoveryMod I have the stock ROM on my sd card.
I. I choose install zip from sd card.
II.Choose the correct zip file and start flashing.
III. Choosing Wipe Data/Factory reset will take the device into a complete hang. unless I first use the mount page to mount the System/Data
IV. I reboot the device and ..... you know nothing changed.
so thats my story.
Still hope to find something about it.
Thanks...that was helpful. But now I want to know the following:
Were you rooted before the trouble started?
What did you do to recover?
If rooted, what version of CWM recovery did you have installed? Did you do a nanadroid backup? (I guess the answer is no, because you could have just restored with that).
What recovery are you accessing when trying to flash a zip file?
If you can answer these questions I will continue to wrack my brain trying to recall where I saw that thread.
Edit: please check out this thread http://forum.xda-developers.com/showthread.php?t=1370312
Some of what I said to him may help you .

[Q] Bricked phone, any way to fix it?

I installed deodexed 4.2.2 stock when i was running deodexed 4.2.1 stock. i felt that it was buggy, so i went into cwrecovery and wiped it and i was about to begin reinstalling deodexed 4.2.2 again when i noticed i forgot to put it onto my phone. then i tried to use my phone, and it would be stuck at "unfortunately, system ui has stopped". it never leaves that popup, so i can't enable usb debugging. i can't use recovery mode, because when i do, the android with a triangle caution sign is there, but no options to select from. i can enter fastboot mode, but that's about it.

Everything will be lost. Considering your phone is bricked there is no way to pull the pictures from your device.
Edit: you might not have to flash full stock, just the system.img that will allow you to overwrite the current system and maintain your sdcard.
i do not know if this is the best place to post this considering i am brand new (i hope so) but i have a soft bricked nexus s 4g that i am trying to fix.
it was loaded with the helly bean 4.2.2 custom rom from nexus hacks (sorry no links) after the reboot it went to a black screen.
what ive tried:
odin: flashing a new rom, this resulted in odin not finding the device (usb debugging is not on and i cant turn it on)
fastboot: (i have all the files but i cant seem to get it set up, i type in adb or fastboot (no device recognized)
nexus root toolkit: (wouldnt find the device and found no options to help with usb debugging)
dfs: (couldnt read the device)
plugging in the phone to the computer: it makes the noise that it is plugged in, comes up as f drive but it is greyed out and i cant click on it (says insert disc)
clock work recovery: i did a full data wipe and required wipes cache and delvik or something along those lines: it reboots into the rom and nothing has changed.. my guess is because there is no back up of the original rom and the cfw is trash, it just wipes the bad rom back to factory and that is still a problem.
pda net: wont recognize the device
galaxy nexus toolkit: nothing useful since the usb debugging is not enabled.
ive worked for 6 hours as of last night to figure this out. i have spent most of those hours in forums and delving further into this phone then id imagined (its not mine) so if there is anyone out there that can suggest anything id appreciate it. this has got me stumped and amazed how such easy fix can really be this complicated.. i will thank any and all answers given to me

You need to be in the bootloader for fastboot to work. Reboot to bootloader and try flashing a recovery.img using this command.
fasboot flash recovery recovery.img

will my computer even detect my phone? usb debugging is off and i can't see the phone's storage from my pc.

LG G2 Fastboot

Everything I found on this says volume + and power, which kicks me into download mode, not fastboot.
I've gone into adb and typed adb reboot bootloader, but that just restarts the phone and turns in on like normal.
I google the how to enter fastboot mode on LG G2 and can find plenty of post about being stuck in fastboot, but nothing on how to get into fastboot in the first place.
Found a tutorial here about setting up and using fastboot and thought I was set until I got to the part about "and using fastback", where it just says:
Make sure you have android debugging turned on in your phone (not really needed for fastboot but you do need for ADB), plug it into your computer and boot into fastboot mode...
I felt like watching "Much ado about nothing" when Denzel says; "The learned constable is too cunning to be understood"
Any direction is appreciated.
Hmm, I may have written that guide... Just checked and yeah should have been more clear I'll change that up. It should have read the USB debugging was needed for adb (not for fastboot) so when you can issue
adb reboot bootloader
But after that I did mention to check device specific forum for answers on how to get into fastboot/bootloader and being I've never held an lg g2 I took a quick look around.
Unfortunately the only way that I found that people said works every time is to wipe recovery to get into bootloader mode as the recovery you guys currently have disables something due to a patch getting custom recoveries to work
So yeah, I would advice to speak with someone knowledgeable about your specific device before you just wipe recovery
Out of curiosity, is there something specific you need to do with fastboot or are you just curious about your phone?

the current thing I've been trying to straighten out is that despite being rooted and installing TWRP, I can't install ROMS. I tried CM 11 and Hellfire so that I could put kitkat on, but gave the following:
Error executing updater binary zip.
One of the answers I found said that I had to go back to TWRP 2.3 (I'm using 2.6) and I believe that's where the whole bootloader thing came into play, because it was the way to 'downgrade' -
So then I found Philz touch 6 (as I understand it a mode of CM 11), but here he talked about fastboot and lokifying items. Here's the link:
http://forum.xda-developers.com/showthread.php?t=2554053
In the end it still comes back to the "can't load ROMs" issue. Just want a completely stripped down Kitkat that I can add the stuff I want without the bloatware.
Thanks in advance.(and the thanks button was hit on your reply)
For KitKat you should need a newer recovery with SELinux support which I believe is 2.6.x and newer for twrp, 2.3 I doubt would work if there even is one for your phone
But yes fastboot is often the best way to change recoveries but not the only way.
If there is a flashable.zip you could install new recovery from old
If your current ROM supports the flash image binary you can use a terminal emulator
You can use adb to install
Or even apps from the market
I would look for the latest recovery for your device, twrp, cwm, shouldn't matter so long as its new and then find what way works best changing for your phone.
The update-binary issue is often a sign that you need to change recoveries
Unfortunately without having your device I don't know if I can give you the best answers but feel free to ask
Best of luck!

Thanks again. I have adb and the script for loading TWRP 2.6.xx. I unrooted and rerooted the phone, because I wasn't sure how to replace the recovery... Now I think I realize that I could just find another recovery image and place it in the same file as the loki flash and that will flash it (At least that's what I understand at present).
If that's the case, then downloading the Philz touch 6 would work... but not wanting to brick it, I'm still asking and reading.
Hello Guys.
I am having a similar issue. I have a new ROM that will not run because of a faulty lg set up wizard that always force closes and I can not get passed it and a nandroid that for some reason is corrupted. So. This fastboot seems to be a dead end it looks like a quick learning curve of ADB is the only viable answer. I have installed all SDK Manager with ADB Tools and also the required Jarva JDK and LG drivers. The phone is turned on (at the beginning of the faulty setup wizard) In CMD my device is found when typing in 'adb devices' So. I am already to push a new ROM over to the phone.
Do either of you guys know the adb command?
Help would be appreciated.
Thanks
You can't actually flash a new ROM with adb, but you can either push it phone with adb and then flash in recovery. Or if your recovery has an option for adb sideload then use this.
Also setup wizard crashing is usually the fault of wrong gapps or not wiping before flashing a rom
Sent from my Nexus 4 using XDA Premium 4 mobile app
I found that the best way was to load flashify, that did the trick so I could start trying out ROMs... so no on to the next step - finding a 4.4.2 stripped down stock and the LG stuff I actually like.... thanks again.

Thanks for the reply!
I know it's not possible to flash a ROM via ADB. I have everything set up, ADB etc, etc. My phone is turned on and adb is seeing it but I can not work out the command to push. Every time I try to push I just get a long list of ADB instructions (I think they are) but nothing gets pushed. I have read lots of instructions on how to make the command but I still must be doing something wrong.
Here are my parameters;-
adb push/C:\Users\dene\Desktop/cm-11-20140210-SNAPSHOT-M3-d802.zip/sdcard
Am I missing some spaces I am not aware of? Are all my slashes the right way round and in the right places? Is my 'sdcard' destination designation correct seeing as there is only internal storage on the G2?
Another problem I am having is that ADB has no problem seeing my sevice EXCEPT when I boot in to recovery (TWRP). When in recovery I lose coms between my device and pc. Hence I can no do TWRP ADB side load (I have tried). I have all the correct LG drivers loaded. Except MTP keeps failing to install? Any ideas?
Not to be mardy about it or hassle you but I am fairly house bound and live out in the country and really require my mobile phone. I have spent many hours trying to figure this out. Any help with the above would be much appreciated?
PS. I did a very thorough wipe, I always do. The gapps are built in to this ROM!
Thanks

Glad to here!
You need a space after push
But it usually easier not to enter the location of a file while pushing so cd to the directory first like
cd C:\Users.....
Then once there adb push /nameoffile /locationonphone
But if you don't want to cd, I see you have widows, depending on version you can just right click in the folder your file is located and choose open cmd here

What to do to unbrick the phone and bring it back to live. I tired the adb and fastboot cmd method on windows 10 and windows 7 but no success. It's just stuck at writing .img file.

Dear guys,
due to problems within this morning, i restarted my phone to wipe dalvik/cache.
But it occured that TWRP somehowe needs to have a password (which i didn't ever set though).
Didn't boot up at all now. Even with toolkit no chance to do anything with the device.
Any further suggestions/ideas?
Try flashing the factory image without using a tool kit. Google nexus 4 factory image. Download it to your pc and extract it. Run the flash-all.bat you'll find in there.

Some Partitions of the phone have got some bad blocks causing it to act in such a way !! Seems RMA(if available) is the best recourse since there is no definative solution to this problem !! You can try hard reboot as well as someone once pointed out that his n4 magically restored during it but others dint have that much of luck !! Also u could give LGNPST a try but since that also writes the partition it is highly unlikely to get you through !! One Solution I know will surely work is Qualcomm PST using the HighSpeed USB Device . But unfortunately we need an expert help, probably a Qualcomm employee to get in touch with since the tool has still not been cracked by anyone for n4 though I read somewhere that someone was able to restore using QPST !! Also mostly a JTAG Repair can help you but thats a rip off !! I'll anyday prefer a official LG/Google Repair over a JTAG !!
Hope you find my post useful !!
THanks Guys,

I was afraid of that. Try one thing. Relock the bootloader, fastboot oem lock, then re-boot and see if the bootloader locks. If it doesn't, and it probably won't, then rma is your option.
Edit, haha, I just read that thread you posted and they tried the same thing

i was already trying that. at first it seems that the bootloader got locked again but right after restart it is already unlocked again.
I guess RMA will cause problems due to the fact that it was a rooted Nexus, using a custom rom.

Google seems to have been pretty good with rma's when it's a hardware failure. Pretty sure your emmc is borked. But you never know until you send it in. Hopefully there won't be a problem.

Ok I'll give it a try on monday. But as far as i know, i'll need to call them first.
I could imagine that they'll try to let me wipe my data or give me any kind of instructions to see if they can resolve the problem right away? What do i tell them?
At latest when they'll lead me to the recovery i'll get stuck using TWRP at latest.
Any kind of conversation dialogue i can follow up?
Let's try one more thing, inside the factory image is a zip file, extract that. In there is recovery.img. Put that file in the same folder as fastboot.exe. In fastboot try fastboot flash recovery recovery.img
If it works it'll put the stock recovery on.

Nope, same issue " flash write failure"
I can't get any kind o access...
But don't leave any more thoughts on it. Won't work though, i won't want to bother you all the time

It won't let you flash that either to the best of my knowledge !! Just don't tell those operators that you have unlocked your bootloader and have a custom recovery !! Basically they won't tell u to go into stock recovery !! They'll just ask you hard reset the phone using physical keys !! Bdw check my pm !!

Np, not sure what to tell them. It still boots I assume so you can't tell them it won't boot. I guess just the truth, it is a developer phone after all so it should be flashable

Nexus10 is restarting at start

Hello guys !
I got a Nexus 10 looping up at start after displaying "Google".
Looking on the web, I know how to reset the firmware, but I don't want my datas to be wiped, I need to backup my files first.
Does anybody has a solution in order to get datas back?
Thanks in advance for you help

More information would be nice. Did it just start doing that randomly or were you flashing something? Are you using a ROM or stock? If a ROM, which one?

Hello
What do you mean by "using a ROM or stock?"
I just rebooted the device and then could never boot again normally.
thanks

Then I'm going to assume you haven't installed a ROM on it and are running the Stock OS that came with the device. What method did you use for rooting?

"rooting" ? you meant rebooting? if yes was the normal use with the OS rebooting button.

I misread your issue. I thought you said you rooted it and had issues. I have no idea why it would do that if you haven't even done anything to it. Devices just don't not boot unless you did something to mess it up or the device is broken. If anything try just booting into recovery and wipe cache. If that doesn't work try flashing the system.img found in the factory images using fastboot. Or flash all but userdata.img. There are tutorials around the web. But again, if you haven't rooted the device or done anything to the system files, I don't know why it's not booting. Hopefully the internals didn't go out on you.

I have never personally used this method, so I can't tell you what to do with 100% confidence. But if you can boot into the bootloader and then use fastboot to install TWRP recovery, there may be a way to pull files from your device using commands on your computer. You may have to do some research on that. Sorry I can't be more helpful. It's hard to know what's going on with your device when you haven't done anything to cause it.

Here's a link to their website for a download and instructions. But you need to have the android SDK installed. Do you have that at least?

Please don't rush into anything and start flashing stuff. It will just mess up things even more.

But doesn't he need to unlock the bootloader before he can install a custom recovery? And if he does that, his data is gone.

I forgot all about that part.
@akaii78, I guess forget what I said. I don't know how you can get your data from your tablet now.
Hi,
You can try going to stock recovery and check if you have adb access with it. Then if you have, you can just pull the files using adb pull command. If you manage to connect to adb I can provide further help.

Hi,
Android Debugging Bridge (better known as ADB) is a way that the computer can communicate with the android device. I suggest you giving a read at the following pages to get a better understanding:
