I apologize if this question has been answered already, but I just spent 15 minutes using the search button and could not find a response.
I just installed Matr1x v10.5 (http://forum.xda-developers.com/showthread.php?t=2007231) onto my Nexus 4 but it had JB 4.2. Based on the version notes of the thread, I assumed that it was backwards compatible with my phone and therefore installed the new version on my Nexus 4. Now every time I turn on my Nexus 4 the screen is blank. What can I do to fix this issue? Will it require a reset so that all my data is lost? Thanks.
What do you mean with '... The screen is blank'?
Can you get past the google bootanimation?

Nope, basically once I turn it on I see the "Google" text, and then the screen goes blank as in it's black. Basically the back light is on and you can see that it's on but the background is still black.

Go into recovery and flash the stock kernel. If that doesnt work you need to do a full wipe and reflash the rom.

Theoretically, if I flash v10.0 (which accommodates JB 4.2) it should fix the issue right?
I'm at a dilemma because I do not know if there are any other ways to insert the kernel into my phone as there is no microSD option on the Nexus 4. Does anyone know how I could potentially get the file into my phone?

Can you access recovery? If yes mount your storage and you can transfer the files.

I had already tried that, but once I connected my usb into my laptop I still couldn't transfer any files over.
In the end I reset my phone to factory settings, so the display still shows "Google". Just to confirm, the reason why this logo has been displayed on my phone for a while is because it is working to restore the factory setting (e.g. OS) correct?

I can't tell for sure since it never happend to me but I don't think if you choose to reset your phone to factory settings it will stay at the google logo.
If you choose to reset to facory settings I think you just will boot into recovery with that an android standing with something in his belly with a loading bar.
You can try this.
1.Boot into bootloader.
2A.Flash TWRP with the fastboot command and go to step 3.
2B.Flash stock N4 image with the fastboot command and profit!
3a.Try to mount storage and transfer another rom.
3b.Restore a backup.
Hopefully this works.

I have tried the above instructions up to step 3 because it did not work for me.
It shows the only files in my internal storage(/sdcard) are a file that says (Up A Level) and TWRP. Also, whenever I want to reboot it prompts "No OS Installed! Are you sure you wish to reboot?" At this point I am only interested in a factory reset now so that I can reinstall the initial JB 4.0 that came with the Nexus 4 and then upgrade to JB 4.3. However, whenever I do factory reset via recovery mode, I am stuck with an empty phone with the files I mentioned above.
What can I do to fix the situation? Thanks.

I think the reason that a factory reset won't help since there is no OS on the phone so it cannot reset something that isn't there.
And with the steps I mentioned, can you get into bootloader or does it directly boot into recovery.
Another thing you can try(I don't think it will work but I never tried it so you never know)
Download this toolkit:
http://forum.xda-developers.com/showthread.php?t=2015469
There is an option to flash to stock completly, that will maybe do the trick.
Good luck!

I can get into bootloader fine, it does not boot directly into recovery.
My Nexus 4 is already flashed with TWRP. I have installed the program from the link you provided, however, I have not used it to flash my phone again as one of the prerequisites to using the program is selecting which OS version I am using (at this point I am not using any) and want to prevent any further issues from occurring.
It seems like I can't really do anything with my phone unless I get a JB OS reinstalled, which is what I am currently struggling with. I am presently trying to find a way to copy the downloaded Nexus image files provided online into my internal storage so I can install them.

Okay since you can get into bootloader thats great news!
Have you tried to manually download the nexus 4 image from google?
NOTE this are direct download links:

You just have to do the following :
A) flash a recovery via fastboot (fastboot flash recovery recovery.zip)
B) now go ahead and boot from your recovery, and push the rom of your choice, in case you don't have one already inside your sdcard (adb push ROM.zip /sdcard/ROM.zip)
C) flash your recently copied rom of choice to your phone. (if necessary, wipe data, cache and dalvik cache)

I just spent a couple of hours reading through the guides (and trying them out) which led me to several other guides. To be incredibly honest, I am completely confused as there is a plethora of new information thrown at me. I have to pose several questions before I continue:
1) When you say bootloader, are you referring to the fastboot bootloader screen that pops up after holding the volume down button and the power button? I just wanted to confirm this as I am starting to feel you are referring to something different after reading several guides.
2) Is the scenario 2 guide you posted basically a method to "sideload" the JB 4.3 into the storage of my Nexus 4 so I can install it via Recovery Mode?
I tried installing the drivers but I cannot seem to do it successfully as I do not even have a starting OS for my phone in the first place. I can not access a theoretical "Developer Mode" either from when I first rooted my phone.
So basically, I do not understand how I can get the direct downloads from Google (the JB 4.3 files) and get them into the internal storage of my Nexus 4 to install the OS.
Is there a simpler way to do this? If not, here is my current progress. At the moment I am stuck at this guide (http://forum.xda-developers.com/showpost.php?p=34552123&postcount=1) from the previous link you linked and am between C-D. I cannot get my laptop to recognize my device via fastboot devices in command prompt (D). To be honest, this is the second time I've seen this guide but could not get it working properly which is why I used the file provided at (http://forum.xda-developers.com/showthread.php?t=2015469) to root my Nexus 4.the OS[/B].

Yes, the bootloader is the one where you press vol down and the power button together, that's the place where you select to go to the recovery, use fastboot.
First thing you got to do is turn on your phone on the bootloader as mentioned above. Then, assuming you downloaded this: [NEXUS 4 TOOLKIT V2.0.0] from here http://forum.xda-developers.com/showthread.php?t=1995688, open up command prompt and go to this address with "cd C:\Google_Nexus_4_ToolKit" or where you decided to install your toolkit. On windows explorer, go there and rename fastboot-toolkit or whatever it is called to fastboot to make things simpler.
Type in cmd: fastboot devices to check if it recognizes your phone.
If it doesn't; then install these drivers (you should have your device already connected via USB to your computer): https://www.dropbox.com/s/a808emeelvxkwyc/usb_driver.rar
Go to Control Panel\Hardware and Sound > Device Manager. Your phone should appear with an exclamation mark somewhere, right click it and click on update driver:
-Click on browse my computer software
-Let me pick from a list of device drivers on my computer
-Have disk
-Browse for where you downloaded the drivers I linked you to then click ok.
-You should find within the next page something that says Android Bootloader Interface, double click it and finish the installation.
After that's done, then type in fastboot devices on cmd again, it should show up now.
Then, go to here and download TWRP 2.6.0.0 http://techerrata.com/file/twrp2/mako/openrecovery-twrp-2.6.0.0-mako.img , that will be your recovery. After you've downloaded move it to C:\Google_Nexus_4_ToolKit to make matters easier.
NOTE: IF YOUR BOOTLOADER IS LOCKED YOU WILL HAVE TO UNLOCK IT , this can be done by typing fastboot oem unlock on command prompt
Now, simply type in this command: fastboot flash recovery openrecovery-twrp-2.6.0.0-mako.img you will now have a recovery on your device.
With the volume keys, choose to boot from the recovery. TWRP will load, while its loading, rename adb-toolkit to adb to make things easier. When its done loading, type in adb devices to see if it recognizes your phone, if it doesn't use your drivers again but this time instead of choosing Android Bootloader Interface, pick the one that says ADB.
When that's done, and it recognizes your device with the adb devices command you can now proceed to "push" or "copy/move a ROM you've downloaded in your computer towards your phone".
Of course you have to download a ROM, like Paranoid Android for example: http://goo.im/devs/paranoidandroid/roms/mako/pa_mako-3.69-20130722.zip , along with its GApps: http://goo.im/devs/paranoidandroid/roms/gapps/pa_gapps-full-4.2-20130719-signed.zip
You might have to even update your radio and bootloader in the future too, but let's leave it at that for now.
After you are done downloading the ROM of your choice, then type in these commands (assuming ADB works)
adb push pa_mako-3.69-20130722.zip /sdcard/
adb push pa_gapps-full-4.2-20130719-signed.zip /sdcard/
Having moved these two files inside your phone, now its time to flash them.
1) Go to Wipe on TWRP and simply swipe to factory reset
2) Go back and click on Install, look for pa_mako-3.69-20130722.zip and then add pa_gapps-full-4.2-20130719-signed.zip to the queue, swipe to install.
After that's done, simply reboot your phone and it should start booting up Paranoid Android and you're done. Might give you a few issues if you have an old radio and bootloader, but that can be fixed by flashing the new versions of these two in TWRP. Can be found here: https://www.copy.com/s/JniBu/4.3 files (mako) (these can be pushed via ADB like before, or you can simply download them on your phone when its working)
Hope this helps, don't think I can be more detailed.

The first thing I'd like to do before reporting my progress report is to thank you and failly for taking the time to help me out. You both have contributed tremendously in trying to help me out with this, so I would like to thank you both for that.
1) I had installed the sdk program and changed the adb path (following this guide http://www.redmondpie.com/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/)
Following wammie's guide:
2) Booted into bootloader
3) Downloaded and installed NEXUS 4 TOOLKIT V2.0.0 (had used it before but it didn't work for me so I relied on a different program to root my phone). Renamed fastboot-toolkit to fastboot
4) Typed fastboot devices in in cmd, does not recognize phone
5) Uninstalled current usb drivers and installed usb drivers provided. The driver I chose to install for was titled "Android". The other ! mark was "Base System Device" which was something I had never seen before until today when I had reinstalled usb drivers
6) Typed fastboot devices in cmd again and still nothing has changed
I am unable to continue any further as fastboot does not recognize my phone when I have it under bootloader. I had downloaded all the files that were recommended in your post. I think the reason why I cannot access fastboot devices is because there is literally no OS running in my phone. I could be wrong though.
I guess I'll take a break and call it a night since I've been trying to fix this problem the past 13 hours or so. Any additional feedback and support is appreciated!
Additional Notes: I have tried this both on my laptops (Windows 8) and on my desktop PC (Windows 7)
Luckly, if windows doesn't recognize your device while in fastboot it isn't because you don't have a OS installes but because not correctly set up drivers.
I posted a link some posta ago about a toolkit:
http://forum.xda-developers.com/showthread.php?t=2015469
When opening the program at the top there is a button called full driver installation, press it and follow the instructions.

This is what you should do when you are updating the drivers, its imperative you get those drivers working. Otherwise, you won't get access to fastboot.
Oh I would recommend using a Windows 7 PC.
Windows 8 can also do the trick but you maybe need to disable driver signature enforcement, so you better go with windows 7 for now.

Status Update:
I had spent a whole day reformatting my Windows 7 machine and am back at it. I have made a bit more progress than before.
1) After typing in fastboot flash recovery openrecovery-twrp-2.6.0.0-mako.img in command prompt, under the "List of devices attached" it is blank (i.e. there is no device attached). http://i.imgur.com/TnyBCKS.png
2) I have successfully installed the usb driver on my PC the first time when the only explanation mark was titled "Android", however the only Android option at the moment now is labelled "Android Bootloader Interface". No such thing as ADB (or any variations including Android ADB Interface) exists.
3) In TWRP Recovery mode, I see an exclamation mark titled mako but I believe that is irrelevant. I have tried installing the drivers to this just in case but failed. I then tried it again in Bootloader mode and mako is gone and Android Device pops up again with "Android Bootloader Interface"
4) I have tried restarting my PC and repeating the above steps.
Edit:
5) The only time I see an Android Composite ADB Interfaces is when I boot normally to the "Google" screen. However, I cannot move any of my ROMS over into my phone. When I typed "adb devices" it shows a bunch of characters with offline beside it. I do not have any options to reinstall any drivers for this.
From my understanding,I should be able to access the Android Composite ADB Interface while in recovery mode, which should let me transfer my ROMs over... but the issue is I cannot access Android Composite ADB Interface while in recovery mode.
Also, is there any reason why I shouldn't use the official JB 4.3 img as the ROM I want to install on my phone?
I went to update to KitKat and it was nearly done and then the "No Command" error came up. My tablet has an unlocked boot loader but isn't rooted. However it was before but I updated it from an OTA and that got rid of it. I've tried booting into recovery etc but the same thing happens.
Anyone have any advice please?
Same exact issue and set up here. Also, maybe I'm just dumb, but I can't get my tablet to turn off either. It just keeps cycling back to the "no command" screen until I do something.

I think that both of you what you see (the "no command") is your stock recovery, if indeed you see an android with a yellow !.
If it is the case to access the menu of the stock recovery press power and tap volume up. The menu will give you the choice of rebooting your Nexus 7.

I can get to the menu but when trying the reboot option, it just cycles the same way again. Back to the android with a red ! and says "No command." I also tried clearing cache and data to no avail. I was going to try using ADB to manually push the update but my computer was recently updated and now I can't get the driver installed for some reason.
I spent too much time messing around with and learning how to do things with my SIII and not enough time with this
Same deal here! Not sure what to do short of wiping and losing my info.
Same here...any advice? Not sure what happened. OTA update too.

Wow, this seems to be widespread, at least somewhat. I'm in same situation. Toolkits, adb, nothing works. I thought this was a soft brick, but now I'm thinking it's toast. Probably doesn't help that I didn't have Dev options enabled along with USB Debugging. I can't even turn it off. Just bootloops after Google logo shows up twice, then to No Command error, then starts over again. I wonder what the hell is causing this. (Device was locked and unrooted)
Same boat here, even sideloaded the factory image via ADB.

If you have android-sdk-windows installed on your computer do not forget to update it through "SDK Manager.exe".
Pushing via ADB didn't work for me. That also failed.
I caved and called Google. Tech support is stumped as well.

I finally got mine working again!
I tried a million different things so I'm going to try and explain my process as simple as I can, I apologize in advance because I am far from an expert...
First, I tried using the method, well some of it, from this thread: http://forum.xda-developers.com/showthread.php?t=1907796
- I would suggest using this thread to get everything set up (drivers, ADB, the factory image downloaded and in the correct file location) I wasn't able to get the drivers working correctly with that route so I ended up using the toolkit to get them working but that thread helped me get all of the system files in the correct location and helped get all of the ADB stuff set up.
Once you have everything set up and your computer recognizes the tablet, (I checked that by opening a cmd prompt and using the command from the original thread above "adb devices"). As long as you see your device, I think you should be good.
From the "No Command" screen I held down Power and Volume + to get the menu to come up. I then chose the Restart option and immediately held Power and Volume -. This got me into the Fastboot Mode.
Once in Fastboot mode I went to the cmd prompt on my computer and used the following commands in this order from this post:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system -w
fastboot flash system system.img
fastboot reboot
*Make sure that all of the image files are in the proper location on your computer otherwise this step is worthless
The tablet then rebooted normally and I was able to set everything up again. Again, I am by no means an expert at all, this is just what worked for me. Try at your own risk.
I hope I covered all of the steps, I tried a million different things last night so they all kind of run together.
I ended up doing and it worked for me as well. Wiped everything though. How can I restore / reinstall my apps w/o needing to download them all again?
Two things: That guide says you must have USB Debugging enabled. Since my wife had this tablet, I did not have dev options enabled at all, including USB debug.
The other thing is that when I run the SDK Manager, nothing happens on my computer. I double click it or try Run as Admin, and a small CMD box flashes on my screen for a millesecond and disappears. That's all.
My wife's 2012 N7 is having this same problem. Unlocked bootloader, but I reflashed factory image and unrooted before giving it to her. She got the OTA last night, and now stuck at No Command.
I've subscribed to this thread, hoping that you guys will have it solved before I get home from work tonight! Would love to not have her lose all her data.
(I was kinda mad that she got the OTA last night and I haven't got it yet on my 2013 N7, but that's another gripe for another thread)

Two things: That guide says you must have USB Debugging enabled. Since my wife had this tablet, I did not have dev options enabled at all, including USB debug.
The other thing is that when I run the SDK Manager, nothing happens on my computer. I double click it or try Run as Admin, and a small CMD box flashes on my screen for a millesecond and disappears. That's all.

Unfortunately I'm not sure on the SDK manager part. As far as the USB Debugging, I'm 98% sure that I did not have it enabled either. I think I did at one point but after doing several OTA upgrades, I'm sure it got unchecked.

I don't believe there is a way. Maybe someone smarter than myself can chime in but I had to let the play store do it's thing and re-download all of mine.

I finally got mine working again!
I tried a million different things so I'm going to try and explain my process as simple as I can, I apologize in advance because I am far from an expert...
First, I tried using the method, well some of it, from this thread: http://forum.xda-developers.com/showthread.php?t=1907796
- I would suggest using this thread to get everything set up (drivers, ADB, the factory image downloaded and in the correct file location) I wasn't able to get the drivers working correctly with that route so I ended up using the toolkit to get them working but that thread helped me get all of the system files in the correct location and helped get all of the ADB stuff set up.
Once you have everything set up and your computer recognizes the tablet, (I checked that by opening a cmd prompt and using the command from the original thread above "adb devices"). As long as you see your device, I think you should be good.
From the "No Command" screen I held down Power and Volume + to get the menu to come up. I then chose the Restart option and immediately held Power and Volume -. This got me into the Fastboot Mode.
Once in Fastboot mode I went to the cmd prompt on my computer and used the following commands in this order from this post:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system -w
fastboot flash system system.img
fastboot reboot
*Make sure that all of the image files are in the proper location on your computer otherwise this step is worthless
The tablet then rebooted normally and I was able to set everything up again. Again, I am by no means an expert at all, this is just what worked for me. Try at your own risk.
I hope I covered all of the steps, I tried a million different things last night so they all kind of run together.

Worked for me! Thanks, I don't believe I had USB Debugging enabled either. Shame it wiped all my data though.
OK, got mine back up and running! I'll just leave what I did here in case anyone can benefit from it.
I first used Wug's Toolkit to download and install the RAW drivers. (Option #4, I believe) They were the only ones that worked for me. I followed the instructions to install them and then when it looped to the No Command screen, I held volume up and power. This got me to the menu, where I chose reboot. I then immediately held down the volume button and power to get into the bootloader screen, where it (thankfully) stopped looping. Then I unlocked the bootloader using the one-click option. Next step was to download and flash factory 4.4 image using the Soft Brick mode. Fastboot recognized my device and pushed the image. Now all is well. Close call... I've already enabled USB Debugging for my wife on this tablet so that crap doesn't happen again. She did lose all her data but she is happy to have a working tablet again instead of a $200 beer coaster.

For starters this is the wrong Forum Thead to post in, it should be in the Q&A Forum.
Second you didn't use search as if you got here : http://forum.xda-developers.com/showthread.php?t=2541784 it will tell you with clear instructions on how to root the TegraTab.
Please insure that your threads are in the right place. I mean no disrespect but XDA have rules for a reason.
Ahh my bad, I'll try and be more careful. Now, I have read that link there already and it doesn't work. Also now my situation has worsen in that it got updated to 4.4.2.......I still tried all other methods, Vroot, towelroot, supertool etc . Tried to do the manual fastboot also doesn't work, impact or see no device so stuck over there. Has anyone found a way to root?
If Impactor does not find your device fastboot mode, try another USB port. If that doesn't work, try another computer if possible.
Also, make sure that you are running Impactor as administrator by right-clicking the application and pressing "Run as administrator".
Edit: this is a different device
I did try other computers and still no avail, even with admin access. Also HP slate 7 extreme is basically a Tegra note 7 not different device. Just few minor changes. If only the fastboot work, i probably be rooted by now. Is there a way to back 4.2.2? like put the recovery 4.2.2 in sd and recover from the loader? would it brick my device? Also i found out about towelroot modstring, is there a specific modstring for hp 7 extreme? would like to try it.
thank you

In this case unlock bootloader
Flash TWRP and check if it works, if so flash supersu
Hey shaky, thank you for replying. he boot loader is still lock. When device off , I press power n vol up to get into this menu which has fastboot protocol, selected it but nothing happens, then check for driver in impactor, no device detected. So can't use Tom's supertool to unlock bootloader. Also did the command prompt, say fastboot not recognize internal or external etc....
There also a recovery kernel, which leads to a recovery menu that can open zip files, think I can do just flash twrp ?
Thanks

Install fastboot drivers then go to your boot loader menu and type
Fastboot flash recovery twrplocation.IMG, this will flash twrp then boot into twrp (recoverykernel) install SuperSU
Thanks for replying. I did all that was suggested and nothing has changed. Problem is that impactor won't detect my device and won't install driver.
Took these pics to show what i'm seeing (left to right)
1) First pic is when tab is off, I power and vol up to get that menu,
2) Second pic impactor can't detect anything.
3) Third pic is if i select Recovery Kernel, a No command show, did power and Vol up to get this recovery menu
What does the Device Manager show? For instance, when the tablet is in the recovery menu, can you see an unidentified device?
EDIT: What operating system are you running? Are you an administrator? Are you running Impactor as administrator?
In recovery mode, nothing shows up in device manager
In normal tab mode, it show android phone with subset android composite adb interface. Also there a ? MTP
anyone?
Update! : I exchange my tab, now its 4.2.2 and just rooted it with vroot. Voila surprise that towelroot and impactor still not working....
now that its rooted, is there a way to install cmw/twrp? tried the supertool but no luck with impactor so can't fastboot command.
can i just put cmw or twrp in sd and flash it from the android revocery menu?
thanks
Bump....could use some expertise help here
Thank you
From the sound of it you are rooted but not unlocked. So, flashing Roms and things will not work until you do that.
However if I am wrong and you have unlocked the boot loader, go right ahead and flash some ROMs.
I found off another thread that our HP S7E running kitkat can be rooted with towelroot v1. It's a one-click root method. Just download the apk, install and run it, and the tablet will be rooted! Just take note to install supersu from the play store
Root 4.4.2 HP Slate 7 Extreme
See my tutorial here: http://forum.xda-developers.com/nvidia-tegra-note-7/help/root-4-4-2-hp-slate-7-extreme-t2850893
HP Slate 7 Beats Special Edition
Hello new to this thread. Wanted to ask if this root method would work on the HP slate 7 beats special edition, the beats special edition looks very similar to the HP slate 7 extreme, and also the Nvidia Tegar note 7.
Okay, I was trying to load android 6.0 on my oneplus one and I don't have any idea what I've done. I was following the instructions in this video https:/ /m.youtube.com/.watch?v=x8zuQcJHQy4 but I wanted to try to do it without using my laptop. So I downloaded the gapps from here http: //opengapps.org/ directly onto my phone. I restored my phone back to factory setting from the settings menu on my phone, and then tried to follow the instructions from the YouTube video. So I removed my existing op system and then tried to install the the new gapps from the recovery menu. The instal failed, so I went back and fired up the laptop and started to follow the instructions in the video. The problem is that my laptop won't connect with my phone for some reason. I plug it in to the computer but it won't recognize my phone. So I am unable to transfer the new gapps from my laptop to my phone. Now the problem is that my phone will not start up, it just sits on the starting screen (picture attached). What do i do?! I should mention that I have no idea what I'm doing if that isn't already extremely obvious. Please help!
Look as you described there maybe more than one solution to this..
As for me the easiest method would be is to flash a custom recovery by going into fastboot mode. And from there you can boot into your recovery and transfer whatever files you need from laptop to your phone. Then flash your custom ROM.
Recovery link : https://twrp.me/devices/oneplusone.html
Custom ROM: http://forum.xda-developers.com/oneplus-one/development/rom-ressurrection-remix-m-t3270147
Look my advice is don't make this whole process as few steps guide.
Divide it into small parts like first installing recovery. Then second part flashing custom ROM. It makes its easy. And for individual part you can find tutorial online.
Thanks me if I have helped and if you have any more doubt PM me.

Just go into fastboot mode and flow the given instruction..

By fastboot do you mean where I power it up and hold the "down volume" button for a few seconds??
OnePlus One Fastboot
Power Down the OnePlus One
Press and Hold the Volume Up and Power Button at the Same Time
Hold These Buttons Down Until You See the Text “Fastboot”
When You See the Text “Fastboot”, Let Go of the Power and Volume Up Buttons

In order to issue commands to your OnePlus One via tools like ADB and Fastboot, you need to boot your device up into Fastboot Mode. So, instead of allowing your OnePlus One to boot up into regular Android, you are going to do something special which tells the device to boot up into Fastboot Mode. This might take you a few tries until you get the hang of it. There’s no need to panic or worry if you get it wrong. Simple power down the OnePlus One again and give it another shot.

I can boot it up into fast boot mode without any problems, I just don't know what do do once there. That's the part I need help with.

1. You need configured fasboot tools first.
2. Flash twrp using fastboot
3. Reboot to recovery
4. Connect your phone with the computer
5. Copy ROM and gapps to your phone and disconnect.
6. Make a full wipe in recovery
7. Flash ROM and gapps
8. Reboot
1. Follow this guide on setting up adb and fastboot - http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378
2. Download twrp-3.0.2-0-bacon recovery from here - https://dl.twrp.me/bacon/
3. Put the recovery image in the same folder fastboot and adb exe is.
4. Put your phone in fastboot mode and connect to pc
5. Open a command prompt and type "fastboot flash recovery twrp-3.0.2-0-bacon.img"
6. Do Not issue the fastboot reboot command, instead press and hold power and vol down till phone reboots into recovery
I give up, i'm way over my head. I cant do any of this **** because I can't even get the right ****ing usb driver on my computer so it even recognizes my phone. I've tried three different methods and none of them work.

Don't give up.
That's pretty simple if you follow the guide below TO THE LETTER.
http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471
Basically, you just erased the Android operating system from your phone. The gapps is NOT the Android system. Gapps stands for Google Apps (play store, calendar, youtube, etc...). They are just additional apps, like Office for Windows for example.
Good luck!

Hello,
I have a Nexus 6P stuck during boot on the white google logo. Apparently it happened during an update to N.
I have attempted a few solutions I have found either on xda or on other pages but the gist of what I’ve attempted so far is thus:
I have tried to reflash android stock after obtaining it from google : https://developers.google.com/android/images (MTC19T) but the oem option was unchecked so “fastboot flashing unlock” returns with an error.
I have tried to apply an OTA update, again I obtained the file from google (MTC19T) , via the recovery > apply update from adb . But it fails. The error from the phone is:
Code:
E: failed to verify whole file signature
E: signature verification failed
And on the pc side I believe that the failure comes from the fact that my pc has never been connected to the phone via ADB, so it’s unrecognized.
- I have also tried to bypass the adb pc signature issue by connecting a usb flashdrive to my phone via a usb-c adapter but the mount /sdcard command doesn’t work.
I’ve tried a few more esoteric solutions, like booting into Emergency Download (EDL) but my phone just boots into the google logo and stays there.
A few informations on my device (according to the fastboot/recovery screen)
Code:
BL: angler-03.51
Baseband: angler-03.61
Product/Variant: ANGLER-ROW-WN1
6.0.1/MTC19T/2741993
Current Build Number: MTC19T
So, to summarize: Fastboot is locked and won’t work, ADB is unrecognized and using a usb drive pretending to be an sdcard doesn’t work and I’m working with a stock recovery.
I'm looking for a way to bypass the fastbook lock or the adb verification. Or (even better) for anyone here to tell me that I've been going the wrong way all this time and that the solutions involves three easy steps...
Thank you!

Try again but you have to use an OTA that is newer than MTC19T. You still may be able to sideload when recovery is in ADB Sideload mode. There is no way to unlock your bootloader. Make sure you are using a recent, known working copy of ADB/Fastboot. The problem many people can't overcome is that they never set up ADB before or used it on a few occasions, so now the phone is dead they can't get it set up correctly. When the phone is connected in recovery>>ADB sideload update, what returns when you run "adb devices"? Do you have another phone you can use to confirm your ADB/fastboot setup is installed correctly?
Download the Nexus toolkit and then boot into recovery and select on the toolkit "softbrick" , good luck. Private message if you need any help

Hi,
Thank you for your answers.
@v12xke For the OTA after trying MTC19T I downloaded and tried half a dozen images from Google. Previous versions, next version of marshmallow, a few of the nougat versions. The results were exactly the same.
As for adb I just updated my Android studio, and it's not the first time I've used these tools. The process of sideloading the zip always stops at 47% but I can see that adb and the recovery are communicating.
Fastboot devices also detects my device, but I don't have my computer on me right now.
@DavidSantos I already tried the toolkit but it just launched my phone on the Google logo and got stuck there.

That's too bad. Sounds like the storage memory going bad and the write process is interrupted when it hits that area. Thing is, I've heard the same OTA write failure occurring several times at 47%. Wonder what that means? Anyway sounds like @Hipstronaute is looking at a replacement phone, under warranty or otherwise.
