XT926 bricked?

I was trying to take my wife's XT926 back to stock and think I may have bricked the device. The phone was on 4.1.2 and was rooted and I ran this utility http://forum.xda-developers.com/showthread.php?t=2757285
The phone is now stuck on the AP Fastboot menu and here's what it says:
Device is Locked. Status Code:0
Battery OK
Transfer Mode: USB connected
No valid PIV block in SP for system
piv validation failed (system)
fastboot Reason: Boot Failure
usb connected
I cannot get into the stock recovery to do a factory reset. I've tried holding down the volume up button when powering on and it brings up the boot menu, but the phone always goes to this screen no matter what I select.
Not sure if I did something wrong, but I thought I followed all of the instructions. I've done plenty of rooting and tinkering with other phones and this is the first time I've had a problem like this.
Any ideas?
EDIT: This was the only thing that worked for me:

Try this method to factory reset via stock recovery. Note: This will wipe/erase your data.
If your phone is on, turn it off.
Press and hold the Volume Down and Volume Up buttons, and then press and hold the Power button at the same time until the phone turns on. You'll see the word "Start" with an arrow around it.
Press the Volume Down button twice to highlight "Recovery."
Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation mark and the words "No command."
While holding the Power button, press and release the Volume Up button once.
Press the Volume Down button twice to highlight "wipe data/factory reset" and press the Power button to select it.
Press the Volume Down button seven times to highlight "Yes - erase all user data" and press the Power button to select it.
After the reset is complete, press the Power button to select the option to reboot your device.

Having same problem, reset failed
Same problem here too. Stock nexus 5, no clever modifications. Sudden problem on regular old power up attempt. Saw unable to mount /cache in log. Mine failed on Friday 7/10/15. The clearing of cache fails to return. The factory reset says it succeeds but reboot goes right back to the unending boot animation , Hope you have better luck.
Update: Now the clear cache succeeds, factory reset succeeds, reboot stuck still at animation.

both of you, fully reflash stock using factory images.

Major hand holding requeste

Please, can you direct me (us) to a good tutorial on how one reflashes a stock image? I was OTA updated to the latest and greatest as near as I know / assume.
I have a windows pc running win8 and a generic micro usb cable. Where do I find the "image" ?
If there is a way to screw this up, I will.
Thanks for your reply and in advance.

Progress?
Thanks so very much for your kind assistance.
I have followed the guide, unlocked the bootloader and applied the factory image. I think it might be working...
The flash-all.bat showed the following, I'm hoping the error is just noise??? I am in the process of factory wipe/reboot and it is back to the boot animation, but I saw someone say that this can take in excess of 15 minutes....... sweating bullets.
If this doesn't work, can you tell me what you think of this other person's observations????

Well bummer... the boot animation problem is still there. I guess the error I saw above wan't just noise. Can anyone interpret its meaning for me? Any recommended next attempt?
---------- Post added at 11:34 AM ---------- Previous post was at 11:13 AM ----------
I noticed that my PC kept making a noise as if the phone was being connected and disconnected continuously, tried another usb port and it stopped so I tried again. I didn't see any errors aside from some stuff about sig.img and vendor.img missing, noise?
It is trying to reboot again, but I'm getting a little discouraged. Another couple hours for a reboot? Is that what I should expect?

Spoke too soon, was able to repair using your site's guide: http://forum.xda-developers.com/google-nexus-5/help/nexus-5-stuck-boot-loop-lollipop-t3098632
Thanks so much!!!
It is officially dead. No luck at all. Hope someone has more luck than me. Thanks for the help anyway.

[Solved] Sony D2305 stuck on bootloop - Help plz!

Hello guys. This is the problem.
I made a bootloader unlock, did just great. Installed CWM 6.0.13, great too. But when I try to boot the phone just got stucked on Sony logo, and won´t pass from there. Sadly, I ran out of battery, so I searched the "fix low battery fastboot" bat, executed it, and the phone gives me this:
battery-voltage:
finished. total time: 0.000s
rebooting into bootloader...
OKAY [ 0.016s]
finished. total time: 0.016s
< waiting for device >
As you see, there is no value in battery-voltage (is that ok?). After the device is rebooted, gives me a red light led followed by a green light led and then nothing for a couple of seconds. The bat just get there in "waiting for device", and the phone just gives me that led colours. If I need to reboot into fastboot everytime, I press the vol + so I can get into fastboot, and repeat the process of the bat. Besides, charging the phone just doesn´t work. Just restart the logo and won`t do nothing. But what I discovered is that pressing POWER button and vol + while charging, it vibrates, turns on red light led, makes 3 more vibrates, and restart.
Any help possible? Tried EVERYTHING, wiping cache, factory reset, everything.
Thank you for reading, have a great day
EDIT:
After fighting with this phone for 4 days, found on Sony official website that I need to hold the reset button for 120 seconds AND NO MORE. After that, charged the phone for 4 hours aprox. There is no animation of charge, just the logo of Sony but it´s charging.
Installed the S1 drivers so the phone can be recognized by the pc in fastboot. Plugged in the phone in fastboot (hold vol + while connecting to pc until you see a blue led light), downloaded the stock rom for this model (D2305) and installed the rom via flashtool. Restarted the phone after the flashtool finished succesfully and VOILA! Xperia logo and booting like a newborn baby.

Thank you for your reply.
Holded the reset button by 120 secs, charged battery for 4 hours and flashed stock rom via flashtool. Worked like a charm.

Your welcome,love to hear it..hit "thanks" if my post is useful

Mate 8 bricked. Button combo's do nothing :(

I've foolishly tried coming back down from NXT-L29C636B585 ending up on NXT-L29C636B330 after using the roll back update mid-way. I then tried the roll back update again to then flash to NXT-L29C636B211 and now my phone does nothing but show the boot logo and get hot - which in this weather I could live without!
Power+up does nothing, power+down does nothing, and power+up+down also does nothing. I don't have TWRP on, and adb/fastboot commands do nothing as it can't get to recovery. I can't even turn it off!
Is it now a paperweight? The only way to turn it off is to let the battery run down I think as holding power down just makes it restart.

Confirmed - it only turns off if the battery runs out. On giving it charge it then pops up with the logo screen again, and again none of the buttons combinations do anything other than restart it. I think my only option now is to send it off to Huawei. Does anyone have any ideas other than having to send it off?

Did you connect it to a PC before trying power + volume down? Was the reason it didn't work for me before.

Yeah, hold Power + Volume down after connecting it to your computer via USB and you should see go into fastboot mode.

I'll give it a go when I get home! god I hope this works..

YES! FASTBOOT! Only issue now is i'm FRP unlocked, but PHONE locked.. I can use the tool to unlock the phone as I have my password from Huawei, but what then? use the tool to flash one of the recoveries?
Thanks for the advice so far - I was very nearly physically sick when i realised nothing worked..

Try unlocking the bootloader and flashing twrp

bootloader unlocked and I used the SRK tool to flash stock 4.1 so now getting messages about my phone not being secure. Next step I figure is build enough charge in it to try flashing B330 again assuming power + vol up/down is working

bootloader unlocked. twrp 3.0.3 flashed ok:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery twrp.img
target reported max download size of 471859200 bytes
sending 'recovery' (23498 KB)...
OKAY [ 0.500s]
writing 'recovery'...
OKAY [ 0.330s]
finished. total time: 0.834s
However TWRP is nowhere to be found.. I just get the 'Your device has been unlocked' waffle and can't get to recovery still. Left the phone to fully discharge, and on inserting a mains lead to charge it for a while it then auto starts up and goes to the same screen - I try power&up and it just goes to the red charging 'lightning bolt' screen - then back to 'Your device' etc. I have no way of getting into TWRP!
I've been flashing Samsung phones for years and I can't remember ever getting this infuriated on a flash procedure..
I think I may have to do everything through fastboot as that's the only screen I can get to - but the only thing I can alter which seems to make a visible change is locking or unlocking the bootloader.
Should I re-lock with TWRP supposedly on? I have tried, and all I get is the 'not enough charge' screen - regardless of how long it is left untouched on power. It's as if all the charge I am putting in is just going to heating up the back and showing me the flipping message - then it runs low enough on charge to blank the screen, reboot and then end up with the unlock screen.
All I want to do is hold down all the buttons and have it install B211 - B330 - B'anything' from the dload folder on the sdcard I have in there. If anyone could tell me what to do to get to that point i'd be super happy. Failing that is there a way to fastboot flash a rom file?

Make sure to unplug the usb cable in order to get to TWRP.

At the moment i'm just struggling to get back to stock let alone a custom rom! If I ever get back to working phone in any way i'll be happy..
I've extracted out the boot, recovery and system from B330 and flashed them all through fastboot then re-locked the bootloader. It is still starting up with the Huawei logo as if booting up, and stays at that screen - It eventually then goes blank, pops up with the red circle with red charge pic in it, then after a while the Huawei logo reappears. I am essentially no further forward.
The more I flash things the more it pays no attention to me and sits on my work desk doing nothing.
I'm wondering if - in my epic screw-up - I managed to somehow destroy some part of the OS that governs charging, as it refuses to hold a charge while plugged in to the pc, powerbank or mains lead. At least thats what it is showing me.. It stayed powered long enough for me to fastboot flash the system.img, but that is when on the pc usb connection.
When I lock/unlock the bootloader through the SRK tool it finishes with the 'choose lock or unlock then press power' option which then promises a system reset.. and then it turns off with the red power screen. I can flash TWRP but because it is seeming not to hold a charge, I cannot then get into it without cables attached as it just boots back to the red charge screen.
Is there another file from the update.app I need to flash? should I just flash every single image and hope for the best? I really felt I was getting somewhere this afternoon..

Hey,
I unbricked my phone using the same method - thanks for mentioning it! But sadly I'm stuck again. Maybe you have a hint for me?

Can't flash TWRP on Google Pixel

Trying to flash TWRP onto my pixel. I've already unlocked my bootloader, and I'm using platform-tools. I run the command prompt, check fastboot devices and see that my phone is connected and should be working (exactly as tutorials tell me to). Then when I run fastboot boot twrp.img, I see the line:
Sending 'boot.img' <26588 KB> OKAY [0.610s]
Booting OKAY [0.912s]
Finished. Total time: 1.570s
the times chance slightly but it's about that. From there, my Pixel begins booting immediately, which is where it goes wrong, as it doesn't bring me to the TWRP menu. I see the white screen with google, a la phone booting, but it lasts about 5 seconds. From there, my phone shuts off. It is also very difficult to turn back on, requiring me to hold the button for upwards of 30 seconds. once it does turn on, it stays on just like stock. i have no idea what's going on or how to fix it
