[Q] New Nexus 7, Win 7, Nexus 7 Toolkit can't boot into Fastboot, "Too Many Links"
SOLVED!
So I went ahead, tried flashing the stock recovery, no joy (no recovery menu at all - just a bad-android image). After a while, tried flashing CWM touch (via Toolkit) - and now it's working. So, everything seems good now.
----------------
UPDATE 5 - PARTIALLY SOLVED:
So, after the last couple of things, I began to suspect bad hardware, as I alluded in those updates. And I was right.
But... it wasn't the hardware you might have thought.
It was...
(this is embarrassing)
The USB cable.
Yes, the USB cable. It was the wild variations in recognizing the fastboot mode that made me suspicious. Replaced the USB cable with another one and... stability, achieved. Unlock, root, recovery program and SU program all went without a hitch. In fastboot mode, for the first time, the device serial number shows.
HOWEVER - things are not perfect. The recovery mode from the bootloader still gives the bad-android icon.
I just used the toolkit to reflash stock recovery back to the device. This completed rapidly, without error. I then tried the recovery option in the bootloader, but again, no joy.
So at this point, I point a finger partly at the tools used to flash this - they claim there is no problem, yet the flash doesn't take at all, and no error is given. As a sometimes firmware developer, I'm used to flash being followed up by a checksum or other test to verify success of the flash. Is that not being done (shame, if not). If it is, then apparently the flash works, but the software being flashed doesn't? The stock recovery???
Any ideas on how to get this back? I just did the full unlock, which wiped all user data, and proceeded from there. I now have a solid connection, but don't really know how to get things back.
Perhaps I need to manually reinstall 4.2.2?
----------------
UPDATE 4:
So, on a lark, from fastboot in Android, I selected the "Recovery" option - it starts to boot that, then gives the Android with red triangle and exclamation point. So, looks like the recovery was toasted.
This was a brand new device earlier today. It has been completely wiped twice, and none of this has gone away. Seriously: bad device?
-----------------------
UPDATE 3:
So, I thought I'd try the direct approach, as outlined here:
http://forum.xda-developers.com/showthread.php?t=1741395
Device is in Fastboot, Device Manager shows it as ok.
I run fastboot flash recovery <file> -- and IMMEDIATELY get "fastboot has stopped working" - that's right, a hard crash in fastboot. And this is repeatable.
Am I wrong in thinking this looks more and more like a driver problem? I note that fastboot is recognized as a device maybe half the time - the other half, it gets an exclamation point in Device Manger. All I do then is restart the bootloader using the bootloader menu, and usually it fixes right up. But that's obviously a huge red flag, as the device should be recognized every time.
Is this a defective Nexus? The only thing that seems dicey is anything relating to fastboot/bootloader (which is, however, unlocked - or at least it says it is).
----------------
UPDATE 2: Using the "restart bootloader" in fastboot results in slightly worse non-recognition of the device. When I do that, I get a straight "USB Device Not Recognized" from windows - the device manager doesn't even show "Android Phone" as a class of device in this case.
---------------------
UPDATE 1: I found the thread talking about missing entries in the INF file. I added these, and got a somewhat, but not entirely, stable recognition of the Nexus 7 when in fastboot mode. Basically, sometimes it is recognized, other times it is not. By "recognized", I mean that the Windows Device Manager shows the device as "Android Bootloader Interface", with no indication of a problem (which it only does in fastboot mode - it shows as a composite ADB device when booted normally).
However - it seems it fails to recognize fastboot about half the time, although it seems that that is related to reboots - that is, a fresh boot, then going to fastboot through adb seems to work. But restarting fastboot manually fails to be recognized (Windows shows a bang by the "Android Bootloader Interface", and says the device "failed to start").
So, using 4.3.5 Nexus 7 toolkit, I tried to unlock the bootloader. Windows recognized fastboot mode, but the process errored out anyway, after maybe 15 seconds, saying "Too Many Links" - the same error as before.
Again, brand new 32gb wi-fi-only Nexus 7, with 4.2.2 update and the most basic configuration only (dev mode, usb on, etc.)
Any ideas?
-------------------------------------------------------
ORIGINAL
So this is a new, out of the box nexus 7. The only setup has been to connect to wifi, update to 4.2.2, and enable developer mode and USB debugging.
Running latest paid-for toolkit - Update 29 Feb 13, version 4.3.5
Just about everything requires the insecure fastboot, but every time I try any operation that attempts it, I get:
Booting into fastboot mode
downloading 'boot.img' ...
FAILED <status read failed <Too many links>>
I basically can't do anything - in this case, I was trying to backup.
It is being done on 64-bit win7 system that had drivers, and worked for another nexus 7 a couple months ago. But, just to be safe, I uninstalled the drivers, rebooted, and installed.
However, I see this on the home page of the toolkit:
FASTBOOT MODE [If serial shows, drivers are installed]
List of Devices attached
ADB Mode
List of devices attached
<numeric code> device
From this, it seems I should expect the word "serial" to show up if the drivers are installed?
I then unplugged the Nexus, refreshed the menu, and both Fastboot and ADB show no devices.
I then plug in the nexus - I get the usual two tone "device attached" sound, no warning or error message from Windows.Checking the Windows device manager, I see a section "Android Phone" with the entry "Android Composite ADB Interface". There are no unknown devices, which would seem then that drivers are working.
So, another refresh of the main menu, and again, I see, under ADB MODE, a single device ID number, and the word "device".
I don't know what to make of this. Apparently, per the "if serial shows" message in the main menu, drivers a NOT installed. But according to Windows, they are.
This perhaps matches the fastboot failure.
Should I see "serial"?
In any case, what do I do to get the drivers to work properly if they aren't?
And if they ARE working, then what is wrong with fastboot?
At this point, I think the toolkit is broken, and worked a couple months ago.
No, you should not see "serial". Your devices serial number should be displayed under whichever path is valid at that time. If you are in the bootloader, your device serial number should be under "fastboot". If you are booted normally, your device serial number should be under "ADB".

I've since figured that out. There was nothing at all, when in fastboot mode, only ADB. But then I found the thread describing two missing INF entries. I added those, updated the driver, and now the fastboot mode (which wasn't even recognized by windows) is now ok in the Device Manager. However, in the main menu, it shows, literally, "??????????" instead of a serial number - that is, there are question marks instead of serial number, Following that, a few spaces and then "fastboot".
Apparently, there are still inadequacies in the driver as relates to very, very new models running 4.2.2 (which this is).
BTW, I do believe I read somewhere that the stock recovery initially comes up with just the android on his back with the warning sign. You then have to hold power and tap volume up or something like that and the recovery menu becomes visible. I could be wrong, I know I had to do this on my old GNex, and those were the steps that worked.

Interesting. I did re-flash the stock recovery, and could get that without the android image.

That may have been a GNex thing that I am remembering. Either way, I'm glad you got everything all straightened out. :good:
I'm still kinda new at this stuff too, but if you need any more help, feel free to hit me up. Even if I don't know the answer to the question, I'll help you find it.

Thanks! Next is trying to put 4.x on a Samsung Vibrant.
SOLVED
See my most recent post in this thread
______________________________________________________________________________________
Firstly, I've spent the last three days scouring XDA and some other forums searching for solutions and trying various options.
The screen on my N4 has cracked and I've lost the use of the bottom half of the touchscreen. This means that I can't unlock my phone.
The phone is insured and will be repaired, but there are photos of my son's first birthday on the internal memory that I don't want to lose. I'm concerned that the phone will be factory reset during a repair or I'll receive a replacement. I'm trying to access the internal memory remotely to backup these files before I send the phone off. The problem is that I hadn't enabled USB debugging before the accident. The phone is completely stock including the bootloader.
So I can access via fastboot but not via adb.
Q1: Can I pull file from the internal memory via fastboot
Q2: Can I enable usb debugging via fastboot
Q3: The phone is set to display as an MTP device in windows but as I can't unlock the screen, none of the files are showing. Is there anyway around this?
Q4: Purely via fastboot, can I unlock the bootloader, install CWM so to use ADB within it and then return to a stock bootloader?
I think they're my options. Any answers to the above or alternatives would be appreciated.
All of the other threads regarding this, the users seem to either already have CWM installed or they're looking to perform a factory reset. I did consider resetting the device via the bootloader in order to bypass the screenlock but I understand that on the N4 this wipes the internal memory as well.
Unlocking the device isn't needed to pull the files from it, just plug it in and get what you need from the internal memory

On mine if I plug it in it appears as an MTP device but with no files. I then have to unlock the screen and select USB something-or-other from the notificationss bar, then the files appear in windows.
Strange, mine never needs to be unlocked...I'm using Windows 8 Pro btw but it also works fine in work on Vista Business
Only other thing I can think of is the fact I'm unlocked and running a custom ROM, I've never used my N4 stock. It was on CM within 30 mins of receiving the unit!
So over the last week I've managed to solve my problem. I've seen several other people asking for help with no luck so I'm posting this here in the hope that the search function will bring it up.
Firstly, my phone was completely stock running 4.2.2, unrooted, with the locked stock bootloader. USB Debugging WAS NOT enabled. I had pattern lock enabled when I dropped the phone. The screen cracked and the bottom half of the touchscreen was unresponsive.
The phone was insured, but I wanted to backup photos from the device before sending it off for repair/replacement.
HOW I FIXED IT.
Please note, you need at least some part of the screen to be working, specifically, some part of the screen where the pattern lock is.
You only need two pieces of software. The Android SDK and the Nexus 4 Toolkit http://forum.xda-developers.com/showthread.php?t=1995688
If you are running 4.2.2 you will need to update the toolkit. I also had the standard issues of installing the USB drivers for the N4. You need to get to a point where is shows up as an ADB device in Windows Device Manager.
As I didn't have USB debuggin enabled I couldn't connect tothe phone via ADB, but if you put it into recovery mode you can use Fastboot. Hold down the power key to turn the device off and turn it on while holding down Vol Down to load up recovery mode.
If you then start the N4 Toolkit, you should see the device listed as a fast boot device.
From within the toolkit unlock your bootloader.
Flash a temporary bootlader, (option 10) as the touchscreeen was broken it has to be CWM.
Once in CWM you can start to use ADB. Open up a DOS command prompt in Windows, go to your SDK/platform tools folder/ to access ADB.exe and you can use the pull command to copy folders to your PC. At this point, instead you can use applications like ADBexplorer or DroidExplorer to do the same thing through a nicer GUI.
If you'd like to still be able to use your phone, although without the touchscreen, you can load an unstable image to get into android and then use ADB to start changing system settings.
Firstly, before exiting CWM, clear the cache. Without doing this the phone jsut hung on the Nexus symbol while loading the image.
in the toolkit go to root/unroot options and select load unstable image(option 4 and then 6). This will fire you up into Android and it should be set up as you left it.
I wanted to enable bluetooth so to use a keyboard (I didn't have a mouse but this is a better option) from the DOS window type the following command
am start -a android.bluetooth.adapter.action.REQUEST_ENABLE
You should eventually get a pop-up on your screen saying that a request has been made to enable bluetooth. Hopefully your screen is working enough to select enable.
Then I use the workaround to disable the sceenlock, found here -> (http://www.addictivetips.com/androi...e-pattern-unlock-on-android-via-adb-commands/) I found method 2 worked for me. I imagine this will be stopped in a future update.
Method 1
adb shell
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name='lock_pattern_autolock';
update system set value=0 where name='lockscreen.lockedoutpermanently';
.quit
Method 2
adb shell rm /data/system/gesture.key
If either of these methods are successful you will be able to unlock the phone with an pattern, hence why you need to be able to touch some part of it.
From then, my bluetooth keyboard was already mated to my phone to I was able the navigate the menus to turn on USB Debugging, turn-off the screen lock and a few other bits and pieces I needed to do.
I then restarted (I was still working within the unstable image) and on reboot, all my changes had al been applied. No screen lock, bluetooth enabled and USB Debugging enabled.
Hopefully this will be of help to those in a similar position. Thanks has to go to the toolkit though which provides all the necessary access to carry this out.
I should probably add, you can use the toolkit to relock the bootlader if you're concerned about that and if you can't click the screen to enable bluetooth or mate a keyboard or mouse, once you have USB Debugging enabled you can use software like Screencast to control you phone's screen from a PC.
So typically, just as I fill my claim to repair my nexus my wife drops her, smashing the screen even more than I did so she has absolutely no use of her screen. I went through the process again and though I'd post it in a more simple fashion.
1. Reset Nexus into recovery mode (power & volume down)
2. Connect to PC via USB. Install the USB driver from the SDK so that it appears as an ADB device
3. Fire up the updated toolkit. You should see the nexus as a fast boot device
4. Unlock bootloader
5. Using option 10 on the toolkit load up CWM on the phone. This gives you ADB access so can you pull files off the device via ADB although I could access the SD card through programs like Droid explorer.
6. If you want to carry on further and get into Android properly, you'll need to wipe the cache from within CWM
7. Reboot and hold down the volume key to get back into recovery
8. In the toolkit select root options (option 4) and load temporary image (6) If it hangs on the google or nexus logo you've not wiped the cache.
9. With this second phone I couldn't access it through droid explorer as it was popping up as an MTP device but I could pull the files via command prompt or through the toolkit
10. If you have any use of the touchscreen at all you can run the following command which will then mean that any touch will unlock the device
adb shell rm /data/system/gesture.key11. You can activate bluetooth via adb if you have a mouse or keyboard available but you will need to be able to press okay on the screen
12. Any changes you make in the unstable android image such as lockscreen, bluetooth, enabling debugging, etc will remain in place when you restart the device.
13. You can relock the bootloader if you wish via the toolkit. You just need to be in recovery mode first.
Hope this simplifies the process
Does unlocking bootloader via toolkit not wipe everything? How are you unlocking bootloader and still able to pull data off?
EDIT: it appears fastboot oem unlock on the Nexus 4 *does not* wipe data!

Please HELP, i can get to step 5...but then, when I try to use ADB via cmd (ie. adb shell), it says "error: device offline". what can it be? I don't know if this is a driver related issue (i've tried the toolkit drivers and the SDK drivers)...i'm desperated, I can't access the phone!!
Thanks in advance
not working for me
i'm in same boat with cracked screen. i can get CWM installed but i cant enabled usb debugging without touching the screen so i cant get adb working. how did you turn on usb debugging without the screen
Thanks for the guide.
Im curious on why youd want to boot an unstable(temporary) image after pulling the files using ADB in CWM recovery. Why not just wipe cache and reboot normally into Android ?
usb debugging without screen?

Can someone please walk me through how to do this? My screen is completely broken, but I can still turn on/off, I have reason to believe debugging is off because when I connect the phone (a Samsung galaxy sII skyrocket) to my Toshiba laptop via a micro USB, it makes a sound to signal that it's connected. Drives E and F then open up (but are empty) and then disappear. I have no idea what's going on but I absolutely cannot lose all of the data on this phone. Pictures and videos from my old blackberry Torch are on here too, making up about 4 years of my daughter's life that I would lose if I cannot retrieve. Also, I am not super -tech savvy, so if someone could help me I would be forever grateful.
Please!!

almost the same issue
I have an Asus memo pad 10 (smart) some of the core apps have been corrupted, (keyboard, UI, launcher etc all the essential stuff) I've been trying to reinstall my UI and launcher from my computer when i found out that USB debugging was disabled. the tablet is basically unusable, i have no way of enabling from the tablet itself. is there a piece of script or something i could run from my PC to enable it?
any help would be greatly appreciated :crying:

My screen became unresponsive a while back. I ended up getting and OTG cable and plugging in a mouse. This allowed me to do everything as if the touchscreen was working. There's also an app called MyMobiler that let me plug in my device over USB and control my screen from my PC. Those two helped me enable USB Debugging, flash a custom ROM, root the phone, backup everything I needed, then restore the phone to stock. I hope this helps.
*Sorry for bumping such an old post*
Thanks for the really useful guide!
Could you or someone just confirm to me that unlocking the bootloader does not factory reset? The reason I'm doing this process is to access my personal data so it's important that I can keep it all.
I ask because at the unlock bootloader stage it implicitly warns me that there'll be a factory reset.
Thanks again!

In that case, I am confused as to how OP managed to unlock his bootloader. He actually states that the purpose of this was to retrieve data, like me.
Also, in a previous comment in this thread by jw95275, they claim that "it appears fastboot oem unlock on the Nexus 4 *does not* wipe data".
I am concerned about the conflicting answers so far, so will hold off for an explanation before I do anything. Thanks for the response!

This did not work for me. I have a Nexus 4 with a broken digitizer, locked bootloader, and usb debugging disabled. I need to grab some data off.
I've tried `fastboot flash recovery {{recovery .img}}` and `fastboot boot {{recovery .img}}` without unlocking the bootloader first, and via both methods, I get back "FAILED (remote: not supported in locked device)"
So I'm not sure how people are able to get into custom recovery without first unlocking BL/losing all their data. Can someone explain?

On some (few) Motorola devices (not nexus 4), you can fastboot boot without unlocking the BL.

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.

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?

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:

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.

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?
First I'm using a MAC...
Sooo... I dropped my phone (STOCK SGS4GE, No root, Locked bootloader) while putting some things in my car and ran it over. Screen is destroyed, so i can't see anything.
I would like to get all my pics and stuff off the phone, and do a factory reset before sending it back to the insurance company.
Doing the reset isn't that big of a deal as I can mirror the buttons pressed blind on the phone as I have access to another.
I have my SIM locked upon boot... not sure if this matters.
(im pretty sure my phone is in debug mode... also wondering if I put in an unlocked SIM, if i will be able to connect.?)
When I plug my phone into my computer, Android File Transfer (AFT) loads, and then an error pops saying no device is connected.
doing an ./adb devices returns nothing.
Putting the phone into download mode, ./adb devices returns nothing.
If boot into recovery mode, and select 'load update via adb'
./adb devices returns
List of devices attached
cb4cxxx8 sideload
So far this is the only way I can get ADB to recognize the device, but as some of you may know... it appears what I can do is limited; I am unable to shell into the phone etc.
Anything I am missing/Any ideas for me getting my crap off the phone?
Help?
Hello all! I'm having a problem with a Nexus 7.
This is my brother's tablet that he hasn't used in a few months. It hasn't been unlocked or rooted.
I can get to the boot screen with the android lying on it's back and the options with the volume buttons. The other info on that screen which might be pertinent:
Fastboot mode
Product name: grouper
variant - grouper
hw version - er3
bootloader version - n/a
serial number -
signing - not defined yet
lock stated - locked
When I go to recovery mode and push the power button, it says "booting failed" in the upper left. It still says Google in the middle, and has the options with the volume in the upper right, but the android is gone as is the text in the lower left.
I have adb and fastboot installed, but I can't seem to do much since the tablet is locked. I tried unlocking a few times, and it's always failed. Usually it doesn't give a reason, but one time I got this: "Failed (status read failed (Too many links))"
I've tried googling this and can't find someone with the same problem.
Anything I can try?
Thanks!

If you can get into the Bootloader, just run the below via ADB
Code:
fastboot oem unlock
Once you unlock the Bootloader you can use the "Soft Brick" Mode in the NRT to Re-flash back to stock and see if that will allow you to boot. You do not need debugging enabled to use the Nexus Root Toolkit if you use the Soft Brick mode, but you must have an unlocked bootloader.

What says "unlocking" (computer or tablet) and are you trying to do it through the Toolkit, or via command prompt ADB? I would first make sure your computer is seeing your tablet (ie. that the drivers and Fastboot are installed correctly). Do you know that they are?

I was trying this with the command prompt. I could get fastboot to list the device when using that command. And the tablet and command prompt both say "unlocking" when doing that. I would assume that means the computer is seeing the tablet and everything is set up correctly?
I think I tried to unlock with the Toolkit, but I believe it told me that device needs to be in debugging mode.
Hey there, I'm having a similar problem.
My info is the same except my bootloader version is 4.18 and my lock state says it's unlocked. I tried to use the root kit but I'm having trouble with the fastboot device being detected. Driver solutions attempted were the google ones, and the pdanet ones. I can't really do the manual thing since that involves the device being recognized when plugged in, and since I can't enable usb debugging... anyways the automated drivers windows says were installed successfully so I don't really know what else to do.
Note: I do know the usb port on the tablet and computer work since when plugged in, it will show that its charging with the white battery icon.
Same issue here
I was in the process of upgrading manually from android 5.0 to 5.0.2 owing to the serious lag that came with lollipop. The OTA was taking longer and testing my patience as most apps were crashing due to lag.
Therefore decided to go for manual flashing of the image. I have never done this before. I was able to make the computer see my device by disabling mtp via storage under setting in the device. This is one thin I noticed to make the device visible to the computer.
After installing the device drivers my nexus was visible within the device manager but it couldn't be seen as an external storage until I played with the MTP. I had even unlocked the boot loader before all this.
So everything was going well and while I started to think all is well, I ran into this issue. From adb I tried to run 'flash-all.bat' from the new device image. Something went wrong somewhere - don't know what it is, but from then on, I am stuck in the fastboot screen or into recovery mode but when i try to boot the device bu hitting the power button - I get this message 'Booting failed'.
I am also trying to use NRToolkit but no use. When I connect my device it is seen in the device manager in my pc but cannot see it as a storage. Therefore when I now try to run the 'adb devices' command it cannot see my device. From what I saw initially, until I enable/disable mtp mode adb was not able to see my device to communicate.
Now when I tried NRT and installed the drivers once again, it is being detected in the device manager but when I run the driver test within NRT - I get a ADB device not found error. Within NRT all that it says is go into device setting>storage to enable it which I know but at the current status of my device in boot screen/recovery mode how can I go in to enable this. This is not helpful.
Somebody please suggest a workaround for this issue. I know I am close to the solution but not sure how to enable the MTP or at least made the NRToolkit to say 'ADB device found'.
My fastboot screen shows these details:
Fastboot mode
Product name grouper
Variant = grouper
HW Version – ER3
Bootloader version – 4.23
Baseband version – N/A
Serial number – 015d21d910141c0a
Signing – not defined yet
Lock State - unlocked
Please help.
