Hi all,
my nexus wont start after (failed?!) flashing with factory image. bootloader and recovery mode are accessable. i have no backup so i need to flash a new img, but my tablet wont be recognized by my computer anymore(adb drivers not working?!). i tried to deinstall and reinstall the adb drivers alrdy. Device manager shows nexus 7 as Android Phone with "Android Bootloader interface" i cant install adb drivers while in bootloader. in recovery mode i succeeded installing the adb drivers and the tablet is shown correctly in device manager... i need help dont know what to do :crying: .. any suggestions ?
ADB and fastboot drivers are different.

ok sry wasnt patient enough to see... ya well this all makes sense to someone who knows what hes doing but to a noob like me? i thought i alrdy installed fastboot drivers since i unrooted the device a month ago? do i need to deinstall the driver "Android Phone with "Android Bootloader interface"" in device manager first, before applying the new fastboot drivers? pls help me through this i think i damaged enough alrdy ..
no. ADB and fastboot require separate drivers. just install the drivers required for n7 fastboot. there was a link in that list.
there are tutorials here on xda, as well as youtube videos and tutorials on other sites. take a little initiative and learn the ropes. it will help you out later on.

Just relax and take your time.
If your tablet can go into fastboot mode, it is fine and will get better; the only thing standing between it's current state and being brought back to life is a little learning on your part.
Now you see what the problems are with using a toolkit - because they hide all the gory details from you, when the smallest thing goes wrong you are totally helpless due to a lack of understanding about what things are going on underneath the hood. And as it turns out, what "goes on under the hood" isn't really all that complicated either if you do things the full manual way.
Which is not to say that you can not simply just use the toolkit again; if you previously successfully installed drivers that allowed you to talk to the tablet in all of these modes:
- fastboot
- adb w/ custom recovery booted
- adb with Android booted
then it is not evident that you need to be fooling with drivers.
I suggest you read this thread, from start to finish
[GUIDE] Flashing a Factory Image with fastboot / return to stock
Then, go over to your toolkit thread and read it from start to finish. You will see that there are & have been plenty of people in circumstances nearly identical to yours.
good luck
hey thx for ur replies! im a lil more calm now than i was 30 min !
the big problem i still have is that my tablet will show up as Androidphone/Android Bootloader Interface not as an unknown device or as the Nexus 7 it is when i plug it in.. so i cant install the drivers am i correct? well i tried it a few times .. deinstalled and reinstalled .. the problem persists? anyone familiar with that? when i change into Recovery Modus it will show up as Androidphone/Google Nexus ADB Interface.. so my first steps to get rid of this mess would be ...?

that does not sound like a problem to me at all.
You communicate with the device using the "fastboot" program when it is in bootloader/fastboot mode, and with the "adb" program when it is in custom recovery boot.
What you see in the device manager appears to be completely normal - In different modes it shows up in different places. It's not supposed to show up with the same driver in different modes.
Code:
fastboot devices
will show you whether you are communicating successfully with the device when it is in bootloader/fastboot mode, and
Code:
adb devices
will show you whether you are communicating successfully with the device in recovery mode.
I suppose your toolkit has some stoopid menu or buttons someplace that will allow you to test for exactly the same thing. Now all you need to do is stop posting here and read a little bit.
good luck

well i did read quite a lot today :crying: i cant find my device when i type in adb devices, im pretty sure i have the right drivers installed since i followed the instructions step by step.
this guy seems to have the same problem: http://forum.xda-developers.com/showthread.php?t=1808076
could someone tell me if this could be a possible solution :http://stackoverflow.com/questions/...e-over-usb-via-adb-devices-from-windows-7-x64
also would it be possible to just get into the bootloader (since thats the purpose of adb drivers and i can do this) and just proceed with fastboot commands ? if i type in fastboot devices the tablet will show up...
In your first post, you indicated that you couldn't connect to the tablet that was in bootloader mode with adb.
And then you were told - once vaguely and once quite specifically - that *nobody* can communicate with the tablet using adb when the tablet is in bootloader/fastboot mode.
As stated previously, use the "fastboot" program when the tablet is in bootloader mode, and use the "adb" program when the tablet is booted to the custom recovery (or the regular android boot if USB debugging has been enabled).
You can use either one of these modes to effect a rescue so long as they are working correctly - they don't need to both be working. Eventually you would want that to be the case, but for the moment why don't you just stick with what is working for you.
If you get a device ID printed when you execute "fastboot devices" when the tablet is in boot loader/fastboot mode, that is all you need to reinstall a factory ROM, using nothing but fastboot.
thx for pointing me in the right direction! so i started flashing with the fastboot commands... as soon i get to: fastboot flash radio radio-tilapia-1231_0.17.0_1025.img

Well, I can't see what instructions you are following, and there is a possibility of sensitivity to an exact sequence. In particular, is a
fastboot reboot-bootloader
performed after the bootloader is flashed, but before the radio is flashed? It might be important that you are performing the radio flash from one bootloader vs. the other. Just a guess. (Along the same lines, do you see something unexpected happening, such as a boot to the recovery after the radio flash command?)
There are some other threads on this I think. (I have a grouper device not tilapia) But I thought that those threads were about problems with radio flashing when a custom recovery (rather than a stock recovery) was on the phone, but that was for applying the OTA package for tilapia rather than flashing directly from fastboot.
-------------------------------------------------------
[Edit] whoops, wait a minute.... "cannot load"
When you run fastboot from the command line, the file names you give are relative to the current directory. Did you move those image files into the same directory that you are executing the "fastboot" command from?
Alternately you can specify the full pathname to wherever you unpacked the files, for instance
fastboot flash radio C:\myfolder\unpacked\googlen7\4.2.2\radio-tilapia-1231_0.17.0_1025.img

I would complete the rest of the steps first and see if everything is still working. Your device *should* still work just fine with an old radio firmware. (Boot it up and see what radio firmware the OS reports on the Settings... about device... status page).
I'll pull down the tilapia image and tell you what MD5 I observe for the radio image.
just to verify, you actually have the 3g/4g model? or just the wifi only model. if wifi only, there is no radio

Also - something to check since you are rebooting the bootloader - does the device show up correctly in the Windows device manager? (Sometimes with soft reboots I have found the need to pull the USB cable and plug it back in to the PC).
Hello all this is my first post here, please be nice
I have absolutely no knowledge of computing/ IT, but after tearing my hair for the past two days (and a lot of googling) I have come here hoping for a solution
I have a stock nexus (see I have learnt new terms) which is now soft bricked and stuck on the X screen
Been looking for solutions including nexus root kit but none have really helped
eg one solution says step 1: install latest android SDK (and in the process of installing I have to ensure usb debugging is turned on, too late already soft bricked)
I am assuming that I have failed because
I have not rooted the device
I have not enabled usb debugging
I have not enabled changes previously eg unlocking
I am however able to enter bootloader mode
I have cleared cache partition and also tried to factory reset but to no avail
Could some one please please help me as it is out of warranty

Unfortunately I do not have usb debugging enabled
And my tablet is soft bricked
Is there a way around this?
Please any help is appreciated

Try this from youtube. I have also softbrick my nexus when ota to kitkat. Use this methods and it works. Also before flash the factory image, unlock your bootloader first. I think this method did not required to enable usb debuging.

You don't need usb debugging enabled to flash images via fastboot -- you just need to be able to get into the bootloader screen.

Thanks for the video
I have followed everything until it (the video) tells me that the process will only work if I unlock my bootloader
Now I can access my bootloader but it states Lock State- Locked
My difficulty is how do I unlock my bootloader as my nexus is stuck at boot loop
I have tried the unlock function on Rootkit, but it says I have to enable usb debugging
To summarise my understanding:
My nexus will get out of bootloop if I flash the ROM
To flash the ROM I have to unlock the bootloader (as per the video)
To unlock the bootloader I have to enable usb debugging (as per nexus root kit)
To enable usb debugging I have to get out of bootloop
To get out of bootloop I have to flash the ROM............
Any simple way of unlocking the bootloader on a soft bricked nexus?
Any help appreciated thanks
like jfmcbrayer said.. if you can access bootloader, you can flash via fastboot either you enabled or not usb debugging, the important thing fasboot can verify your device before start flashing..

Absolutely agree
However when I try to follow your instructions
> fastboot devices
# the following output should be returned
<device serial number> fastboot
I do not get a device serial number
I suspect it is because the bootloader is locked, the device will not be recognised
Happy to be proven wrong because I need a means to get my nexus working

Indeed! Perhaps because the first step in installing an adb driver in my pc is this:
1. Enable usb debugging on your device (found under Settings > Developer Options)
As I have been saying from the start
My nexus is stuck in boot loop
I do not have usb debugging enabled
Is there anyone who can help me with unlocking my bootloader (on my soft bricked stock nexus) so I can flash rom
Thanks in advance

just to be absolutely sure were on the same page I've copied all the instructions from your link
[GUIDE] Flashing a Factory Image with fastboot / return to stock
Notice: If you are going to flash the nakasi android 4.3 JWR66Y factory image, you will need to download the bootloader from JWR66V and replace the one from the factory image. The bootloader in JWR66Y will fail flashing with a signature mismatch error on the device and InvalidState on fastboot.
The objective of this thread is to provide detailed instructions on flashing a factory image using fastboot rather than a toolkit. As good as toolkits can be, I recommend using adb and fastboot directly. This will allow you to see what is happening every step of the way and is a good opportunity to learn about the process. The following instructions assume some basic Windows command prompt skills.
Read all the directions before you begin and perform the steps at your own risk.
Overview
This will restore your Nexus 7 to it’s factory state. All user data will be deleted, so now is a good place to stop and backup anything you don’t want to lose.
This guide is in three parts - basic knowledge and obtaining the required software, driver installation, and flashing the factory image. This and any following verbosity is not to be condescending, but rather not to assume anything.
Basic Knowledge
This guide assumes some basic Windows command prompt skills - changing directories, etc and is written primarily for Windows users. Make sure that you have file extensions enabled in Windows Explorer.
Software Requirements•Android SDK - adb, fastboot, usb drivers
•Java SE Development Kit - required by Android SDK
•A Nexus 7 factory image
•7-Zip - used to extract factory images from a .tgz file
1.Download and install 7-Zip - http://www.7-zip.org/download.html
2.Download the Nexus 7 factory image - https://developers.google.com/androi.../images#nakasi and save it somewhere you can easily retrieve it.
Make sure to download the correct image for your device variant (Wi-Fi vs GSM/HSPA+; nakasi vs nakasig)
3.Download and install the Java SE JDK - http://www.oracle.com/technetwork/ja...ads/index.html
4.Download and install the Android SDK - http://dl.google.com/android/installer_r21-windows.exe
5.NOTE: Notice the install location. This defaults to C:\Users\<user name>\AppData\Local\Android\android-sdk the platform tools (adb, fastboot) and usb drivers will be downloaded to this location. This will be referred to from here on as your sdk directory
6.Run the SDK Manager
7.Under Tools, check the box labeled "Android SDK Platform-tools" - this provides adb and fastboot
8.Under Extras, check the box labeled "Google USB Driver"
9.Press the "Install # packages..." button and follow the on-screen instructions.
10.The platform tools will be installed at <your sdk directory>\platform-tools and the usb drivers will be in <your sdk directory>\extras\google\usb_driver
Driver Installation
This seems to be the most confusing part for many people. Be patient and thoroughly read all the instructions.
Huge thanks to @tetakpatak for taking the time to put together a video showing this process! http://www.youtube.com/watch?v=bhA5C...yer_detailpage..
1.Enable usb debugging on your device (found under Settings > Developer Options)
NOTE: Since Android 4.2 the Developer Options are hidden by default.
To enable them, go to Settings > About Phone, and tap on build number around seven times. A small dialog will appear letting you know "You are now a developer!"
2.Install the abd driver - detailed instructions for installing or upgrading and existing driver on your version of Windows can be found at http://developer.android.com/tools/extras/oem-usb.html
3.Once the driver is installed open a command prompt and change directories to <your sdk directory>\platform-tools (see #2). From the command prompt run "adb devices". This will list any adb-capable devices that are connected to the computer by their serial number assuming your drivers are installed correctly. Recap:
Code:
> cd \Users\<user name>\AppData\Local\Android\android-sdk\platform-tools
> adb devices
# the following output should be returned
List of devices attached
<device serial number> device
4.Use adb to boot the device to the bootloader:
Code:
> adb reboot-bootloader
5.The device should now be in fastboot mode and Windows should be attempting to install the fastboot driver. NOTE: if you had drivers previously installed, you may need to upgrade them. This is the same procedure described at http://developer.android.com/tools/extras/oem-usb.html
6.You can verify that the driver has been installed by running the following command:
Code:
> fastboot devices
# the following output should be returned
<device serial number> fastboot
7.Do not proceed further if fastboot can not recognise your device. You are in driver hell and this must be resolved before continuing.
Extract the Factory Image
In order to extract the necessary files from the factory image archive, we will use 7-Zip because it can do this reliably. At this point you should have already installed 7-Zip and downloaded the factory image archive.
1.Use 7-Zip to open the factory image .tgz file. You should see a single .tar file. Open this file with 7-Zip as well.
2.Inside the .tar file is a directory that will resemble “nakasi-jwr66y”. Open that directory and extract the contents to <your sdk directory>\platform-tools.
3.The extracted files should be as follows: bootloader-grouper-4.23.img, image-nakasi-jwr66y.zip, flash-all.sh, flash-base.sh
Flashing the Factory Image
1.Put the device into fastboot mode by running the following adb command:
Code:
> adb reboot-bootloader
2.In order to do anything useful in fastboot, the bootloader must be unlocked. To do this, run the following fastboot command:
Code:
> fastboot oem unlock
3.Follow the directions on the device, using the volume and power buttons to select "Yes". NOTE: this will wipe all personal data.
4.In fastboot with your device's bootloader unlocked, run the commands listed in flash-all.sh in sequence, waiting for each command to finish.
Follow the commands for your device variant - Wi-Fi (nakasi) or GSM/HSPA+ (nakasig). For convenience I have them here:
NOTE: you will see some messages about the archive not containing boot.sig, recovery.sig and system.sig. That is normal, dont worry.
Wi-Fi devices (nakasi)
Code:
> fastboot erase boot
> fastboot erase cache
> fastboot erase recovery
> fastboot erase system
> fastboot erase userdata
> fastboot flash bootloader bootloader-grouper-4.23.img
> fastboot reboot-bootloader
> fastboot -w update image-nakasi-jwr66y.zip
GSM/HSPA+ devices (nakasig)
Code:
> fastboot erase boot
> fastboot erase cache
> fastboot erase recovery
> fastboot erase system
> fastboot erase userdata
> fastboot flash bootloader bootloader-tilapia-4.23.img
> fastboot reboot-bootloader
> fastboot flash radio radio-tilapia-1231_0.18.0_0409.img
> fastboot reboot-bootloader
> fastboot -w update image-nakasig-jwr66y.zip
After the final command completes, the device will reboot.
5.If you are sending the device in for warranty work, you may want to re-lock the bootloader
Code:
> fastboot oem lock
6.Finally, reboot the device
Code:
> fastboot reboot

You're welcome, mate....
Installing drivers is not difficult, you must read the post by comminus carefully.
I tought it is too a boring part to film it....
@docians take your time to read step by step mate, that guide can help you to unbrick.
Guys, just be aware, that the drivers will have to be instaled two times: once for normal boot mode in OS, another time in fastboot mode.
What might confuse you: the ADB drivers get installed within the SDK and not as usual with downloaded drivers from the website of the manufacturer.
Did this end up being solved?
In the same situation where my Nexus 7 (2012) 4.4.4 is soft bricked and stuck in a bootloop.
Not sure how to go about installing the drivers. Just lost. :silly:

Yes, solved
You will find them in google, search for "google USB drivers for Windows"
Download the zip, unzip it and run the install/setup.exe
After that, boot your N7 into the bootloader mode and connect your tab with the USB cable and wait for 1 minute until it gets installed.
After that you will can execute all fastboot commands. Then just follow the guide by comminus how to flash factory image with fastboot.

You will find them in google, search for "google USB drivers for Windows"
Download the zip, unzip it and run the install/setup.exe
After that, boot your N7 into the bootloader mode and connect your tab with the USB cable and wait for 1 minute until it gets installed.
After that you will can execute all fastboot commands. Then just follow the guide by comminus how to flash factory image with fastboot.

Awesome, thanks.
Have run into another problem now.
Got to the part "fastboot flash bootloader bootloader-grouper-4.23.img"
And I get a message in cmd saying "FAILED <remote: <Invalid State>>"
Then on the tablet it says "Signiture Mismatch".
I'm using the 4.4.4 (KTU84P) from the Factory Images website if that's any help....

Doesn't 4.4.4 image need a KitKat bootloader? Ver 4.23 was used for Jelly Bean 4.3 AMAIK

Hmmm
Well that was the bootloader that was in the 4.4.4 download when I unzipped everything. :/
Is there meant to be another one?
Should I maybe just try and flash a Jelly Bean image onto the tablet then?
Thanks again for your help.
First of all, I know that there are many people asking same thing. I have checked those threads and I guess I am just a little bit more clueless. Last time I was able to use my Nexus 10 was 3 months ago. Since then I tried to solve it many times, but no luck so far. I will try to explain some of the issues I'm experiencing, but I'm afraid I'm not too good with all the expressions people are using on this forum.
1. ADB vs Fastboot
I see this mentioned often and I don't know what exactly it means. It's amazing to me that I can't google it, I'm usually good with googling. I can see that my N10 is sometimes listed under ADB and sometimes under Fastboot devices but I have no idea what I did to change that. I do know that whatever I try to do at certain point, it's always in "wrong" mode, waiting for adb etc. So if someone can point me to a thorough explanation, a wiki or something, that would be very nice.
2. The Loop
I managed to get ClockworkMod v6.0.4.3 installed and it's this loop that device is now inside. I've tried pretty much all possible combinations, wiped both caches, did factory reset, rebooted to system/bootloader/recovery... nothing. Always ends up on same CM menu.
3. Android Toolkit
I have installed this on my computer and tried so many things that I forgot about all details. I tried flashing the big 400 MB stock image to the device, but haven't been successful (says waiting for ADB, even if the device WAS listed as ADB device before I started the procedure). I am also expecting to see the N10 as another "drive" from my desktop, if you know what I mean, so that I could copy files to it. However I don't see it that way, I only see it registered as a Nexus 10 device, like a mouse or any other non-drive device. Is this normal?
So what to do? Can anyone tell me in a simple way, because I am obviously stupid enough to find threads I've seen so far not clear enough. And I would actually think that my computer literacy level is rather high, I think that this Nexus 10 is the only thing that brought me to my knees in last 20 years of working with computers.
And when I say "simple wiki style" I'm thinking of something like this:
Ok. no links allowed, great. It's a redmondpie article named
/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/
This is easy enough for me... but do I assume correctly that all this has already been done with me installing Android Toolkit? If so, it uses a different path structure and I don't see all those folders...
So u do have cmw installed, when u try to flash a ROM it just boots to recovery?

You mean flashing ROM only with CWM, not through android toolkit? Through CWM menu I have tried (many times):
- wipe data / factory reset
- wipe cache partition
- wipe dalwik cache
I don't see way to do anything with:
- install zip
- backup and restore
- mounts and storage
Rebooting menu items do following:
- Reboot system --> reboots to same CWM recovery menu
- Reboot to bootloader --> reboots to the stock bootloader "menu" where I can choose between Start, Power Off, Recovery mode (picking this will reboot to CWM recovery menu) and Restart bootloader (picking this will reboot to this same menu)
- Reboot recovery --> reboots to same CWM recovery menu

3try not to use toolkits, you have a nexus, toolkits are more complicated than manual methods and you won't learn anything from it
Once you have recovery
Wipe all, then you will will need to use adb sideload to flash ROM as you have no ROM on emulated sdcard

The first part worked ok. The second part doesn't.
ADB sideload - I went there in the Nexus menu
adb sideload kitkat2501.zip
returns this:
* failed to write data 'protocol fault (no status)' *
If I do it without starting adb sideload on nexus, then it just says "error: closed", so it does recognize the change.
I downloaded the latest sdk tool, 64-bit, and the stock nexus 10 rom from 25th Janaury.
Let's do this, grab the latest stock for manta from here

fastboot erase system -w
fastboot erase boot
fastboot erase recovery
And extract and run the flashall.bat
This should bring you to the latest official software/firmware. Then with you up and running we can root and give you custom recovery,ROM,whatever

I've been stuck trying to figure out how to adb on my slate 7 extreme for weeks. Tried every driver and every cord and port. So while I'd love to confirm that it is the same... I'm still not sure.
Same here looking for a root
Sent from my HP Slate7 Extreme using xda app-developers app
I was able to root it after some playing around,
you need to use the universal naked drivers (Nvidia Shield) for both adb and fastboot.
To unlock you have to specifiy the vendorid to fastboot:
fastboot -i 0x03F0 oem unlock
The util in the TN7 dev forum will not work out of the box for the S7E because it doesn't specify the vendor id to fastboot, but the supplied files will work (you can modify the .bat if you want to add the "-i 0x03F0" to fastboot). You can boot CWM to install root.
Installing the 4.4.2 system and boot partitions works and it will boot, however i am having trouble with it locking up a lot.

cool. What do you mean by locking up a lot? it often hang and jam? . So i guess, staying at 4.2.2 is the best for now?

It will work fine for up to about 10 minutes, then the screen will freeze and the only way to get it back is to hold the power down for 10 seconds and reboot it.
I am back on 4.2.2 right now, but when I have some extra time I might try a few things.

Is it possible to just have root set up on 4.2.2? Would like to keep all partitions stock if possible (as well as the bootloader). Would this help with stability issues? Sorry if these are noobish questions but thanks in advance

I tried a chinese program without luck. I just bought a keyboard which works with the wrong layout in 4.2 and works perfect with 4.4 which I have on my other devices..therefore I am really looking forward flashing it!
Almost plain tegra
Hi, I agree with @Mobilla I installed android 4.4.2 from this link but be extreme careful, backup your rom first, KitKat works fine but randomly android freeze all system, I tested ClockWorkMod recovery and work flashing root file SuperSU-v1.94.zip but I don't test backup from recovery, well maybe someone can help us to know why kitkat freeze chinese root method is complicated I rooted with this method I don't read chinese I click some buttons and it works. Sorry with my English, I'm from El Salvador, I speak Spanish
I couldn't run 4.4 more than about 10 minutes before locking up, so I went back to 4.2.2 (rooted).
You can download the stock 4.2.2 update.zip from HP's website if you experience the same issues
http://h10025.www1.hp.com/ewfrf/wc/...en&cc=us&dlc=en&sw_lang=&product=6608632#N147
The rooting method is the same as for the TN7 with the exception of fastboot commands you need to specify the vendorid (e.g. fastboot -i 0x03F0 oem unlock) I didn't try the Chinese tool.
You can flash root from recovery once it is unlocked.
I tried looking for what was causing the lockup but I couldn't find anything in the logs. If anyone has any tips for hunting down the problem I would be happy to try.
CWM
Hi, I tested CWM from this link and it works with nandroids backup, but the default storage is strange: /storage/emulated/sdcard0 but in this dir I can't move or delete that backup and use storage space I use a root explorer and can't move or delete, CWM works to root the device with SuperSU-v1.94.zip :good: but not for backup, see ya!
Rooting Slate 7 Extreme
Ok, so I played around with the Tegra Note tools and figured I'd be happy with root on 4.2.2 as it allows me to use link 2 sd to move apps to my sd card. What tripped me up was the vendor id for fastboot. I understood that I'd have to type it out with the unlock command but I just kept punching in 'fastboot devices' to check if the tablet was being detected by fastboot... obviously not the way to go. Hopefully this brief summary of what I did can be helpful to someone else:
1. Download Nvidia Tegra Note 7 Super Tool 2.2
2. While your tablet is off, enter fastboot by pressing volume up + power, you'll see a couple options here - press volume down once and then the power button to select fastboot protocol.
3. Get your usb cable and plug the tablet into your pc.
4. Run the impactor program included in the super tools bundle. Select 'driver scan' from the USB menu, this will load fastboot drivers for your tablet.
5. Start up a command prompt and move it over to the super tool directory
6. Make sure your tablet is seen by the pc by typing "fastboot -i 0x03F0 devices"
7. Unlock the bootloader by typing "fastboot -i 0x03F0 oem unlock" you'll be warned that this voids your warranty, also you'll wipe anything currently installed on the tablet
8. Install CWM recovery by typing "fastboot -i 0x03F0 flash recovery Bat-CWM-Recovery.img"
9. Remove the usb cable and reboot (this is what I did, you can actually just use the command "fastboot -i 0x03F0 reboot")
10. Configure your freshly wiped device, reattach it to your pc with the usb cable and mount internal storage
11. Copy "SuperSU-v1.94.zip" from your tegra super tool folder over to internal storage
12. Turn off your tablet and re-enter fastboot by pressing volume up + power
13. Select recovery, you'll be in CWM. Select install zip from sd card, internal files will be shown so install the SuperSU zip you copied into internal storage earlier.
14. Reboot and you'll have root.
Hope this makes sense, I haven't had any problems with this setup and being able to move apps to the sd card is great.

hi,
trying to flash the breadcrust recovery using my linux pc, but the Z1 doesn't appear in the list of devices when running adb devices. Image attached. Normally I would get a request to accept the RSA key for a trusted pc when enabling usb debug. But I don't get this option.
- Adb tools are loaded and working on my linux laptop
- My nexus 7 responds to ADB devices and shows up ok
- tried on wifes windows laptop with adb/sdk tools loaded and no joy there too
- i have developer USB debug options enabled, i've tripple checked this
could it be the cable? I'm using the one which came with the phone, so that should be ok?!!
cheers
SOLUTION - I ran this One Plus Two script modified with the Z1 device ID and now I can see my device in adb devices and interact with it. I get the SHA screen to allow access and can run commands from linux terminal. YAY!
See the attachments for script.
I think it´s a driver fault. Did u install them in windows?

ADB doesn't work for me, too. I work around this problem by booting into recovery (simultaneously press Vol+ and Vol- and Power until phone vibrates) and choose "Boot to bootloader" from there. After rooting I installed "Power Toggles" from Play Store and use the toggle to reboot to recovery or bootloader.
By the way, when I boot into recovery, I'm able to ADB sideload. So I don't think there's a driver issue.

ok some progress.....
got the trusted device RSA screen to appear on my wifes windows pc. i could then run adb devices and see the device.
I could run adb reboot bootloader, but the device doesn't boot into fastboot, just reboots as normal!
I could also hold down up/down volume buttons and get into the bootloader, but again the device isn't picked by any fastboot oem checks for unlocking!!
arrrgh!!!
You'll have to add -i switch followed by the device ID to your fastboot command. I don't have it at hand, so just read the TWRP thread.
ok! Some progress...ish.
running "adb reboot bootloader"command in windows worked when I switched Cyanogen recovery updates off in developer options. The Z1 reboots into bootloader.
Running "fastboot -i 0x2b4c oem get-device-info" returns nothing just "....."
So I tried "fastboot -i 0x2b4c oem unlock" an error returns cannot unlock use command "fastboot -i 0x2b4c oem unlock-go" which works. The phone wipes data and reboots back into OS.
I re-enable the developer options and adb debug. and reboot into bootloader
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.
weird!
Your commands are simply wrong, thats why they don´t work.
It is:
fastboot -i 0x2b4c oem device-info
fastboot -i 0x2b4c oem unlock-go
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.

Flashing does NOT work on the international version, you have to boot into it directly from fastboot.
fastboot -i 0x2b4c boot z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img
Should be correct instead of the flash command.

What made the change? I was able to see the RSA screen only once, but after device restored to defaults I can't get it back. same drivers installed, and it appears in the device manager.
I honestly don't know, it just worked after many attempts. I read somewhere about USB 3 ports with Linux so might be the same for windows?

It's an USB 3.0 issue. Plug the phone into an USB 2.0 port, or an USB 2.0 hub plugged into an USB 3.0 port and it will magically start working. God knows why this is the case...
Ironically, fastboot works fine even on USB 3.0...
For to be able to boot (not flash) the TWRP recovery you shouldn't need to unlock bootloader. Am I right?

Okay, I have found out that it is impossible to boot from TWRP as log as the bootloader is locked. It just took me 2 hours to setup my phone again after unlock.

This did the trick on Linux (Ubuntu):
- run on terminal "sudo gedit ~/.android/adb_usb.ini"
- put "0x2b4c" in
- run on terminal "adb kill-server" and "adb start-server"
And run the fastboot commands with "sudo".
