[Q] Can't escape fastboot

I am trying to flash my Nexus 7 entirely back to stock 4.3. I was following the guide that is sticky'd in this thread to flash the Google image. This is these are the errors I get:
Code:

Also the bootloader keeps freezing on me after I attempt this. I also am unable to restart bootloader by command or the selection, it just goes to a black screen and "fastboot devices" gives me ????????????? instead of my device ID. I can fix this by turning it off and booting back into the bootloader and it will properly display my device ID.
It is unlocked and on 4.23 that's listed there. What else can I do?

engagedtosmile - You should post this question in comminus' stickied thread. I read all 54 pages of it and he's very good at diagnosing the problem and helping to get it resolved.

Hi, engagedtosmile...
Yeah.. there is a known issue with the v4.23 bootloader.
Your problem could be the bootloader v4.23 from build JWR66Y.... try flashing the bootloader v4.23 from build JWR66V.
See this thread for details (a couple of people have uploaded the bootloader v4.23 from build JWR66V, for both 'grouper' and 'tilapia' Nexus 7's on this thread - when I find the time, I'm going to upload them myself... so I don't have to keep hunting out the link).
Hope this helps.
Rgrds,
Ged.

Thanks but I have done that as instructed in the sticky post (I ran into the error before but was able to flash it fine). I thought I would try to Lock the bootloader and unlock it again, it locked fine but now errors out when unlocking.
I am back to step 1 it seems.:crying:

Have you tried changing to a different USB port on your PC... or a different USB cable, or even a different PC.
I know I've had difficulties, when trying to send/write to 'system', and changing to a different USB port usually resolves the problem... so it might be worth a shot.
Gotta be really careful when flashing bootloaders, as one false move can cause hardbrick, which is pretty grim.

I will have to try it on my home PC later. I have tried different cables and ports on my work PC to no avail. It just won't unlock at all now.

Well, that seems to be your problem. Looks like you flashed the nexus 7 images on your nexus 4...not a good thing.
I would first try downloading the CORRECT images and flashing those.

Bootloop and can't fastboot flash image

I've been having issues with my Nexus 7. The first time it was stuck in a boot loop not making it past the Google logo. I booted into the bootloader, flashed a new factory image, and I was off.
Then a few weeks later the same thing happened. Only this time, I can't get a factory image to flash. Any ideas?
I think my flash memory is gone bad.

It might be helpful if you could be more specific... like, what errors did you encounter?... how did you go about flashing a factory image?... did you use a toolkit, like Wugs?... or just regular fastboot?
For somebody to assist you in diagnosing a given problem, in the hope of fixing it... they need all the facts available... no matter how seemingly innocuous or irrelevant.
The 'devil', as it is said, resides very much in the 'detail'.
Rgrds,
Ged.

Thanks Ged. I guess I was kinda hoping for a tool that could some how test the memory.
Here's the output from the toolkit:

Flash Google Factory Image
Before starting the process your device must be in Bootloader Mode.
In the following instructions you will learn how to do it:
1. Power off the device.
2. Press and hold Volume Down, then press and hold Power.
3. Your device screen should show an image of an opened android.
You're now in the Bootloader Mode! If you don't see the image,
you must follow the instructions again.
4. Please connect the device to your PC via USB.
5. Do you want to start the process? [Y/N]: Y

Not sure what else would be helpful to see/know. Thanks for the help.

I found this thread, which I took to mean to download the bootloader from the 4.3 image. I did that but get the same result.
Also, it shows that I already have 4.23 so it seems like I wouldn't need to flash this in the first place?
Thanks again for the help.

Then skip the bootloader but do the rest of the steps
And you are just using fastboot right? No toolkits

Looks like data partition is corrupt, hopefully fixable but you will need adb shell. So continue on with the steps above and hopefully you can get into either recovery or os, then you can use dd or fsck or something to format, well hopefully so long as it is not too corrupt

It's also "locking up" on most every command that I send. By that I mean, you can't move through the bootloader menu.
Any other thoughts?

Sorry to say but I feel your nand is fried... If you still have warranty you should claim it but as of now I would give it 50/50 that even JTAG would work to resurrect you tab

Nexus 7 (2013 Mobile) fails to boot; can't enter Recovery mode; flash write failure

My Nexus 7 (2013 Mobile) was rooted and updated to stock Android 6.0 a year ago, no 3rd party ROM/recovery is installed. Last week while checking emails, it rebooted suddenly then remained at Google letters and unlock icon, I can enter fastboot mode by pressing power and volume- buttons together, the last line shows status unlocked; then if select "Recovery mode", it reboots then shows a dead robot with an exclamation mark only. I downloaded the latest factory image "razorg-mob30x", connect it to my PC and enter adb command "flash-all.bat" (I modified the bat file by removing -w, so it won't wipe the user data), then it shows: FAILED (remote: flash write failure)
