So I have noticed with my phone (hboot 1.14) I have to DISCONNECT it from my computer while in bootloader to be able to boot into recovery. So I do the following:
With phone in bootloader fastboot mode:
1) fastboot reboot-bootloader
2) While the screen is black, DISCONNECT the cable
3) In bootloader, use vol keys navigate to Recovery
4) Hopefully profit
Give it a try

Can you relock the bootloader? If can then download the official RUU(here is 2.20 firmware http://www.htc.com/us/support/htc-one-x-att/software-updates) and that'll probably save your phone.
oh, you can use the all in one toolkit(http://forum.xda-developers.com/showthread.php?t=1952426) to relock your bootloader if you can.. good luck

You probably corrupted it at some point in this process. You need to mount with your pc and reformat. It happens.

Sweet! Glad I could help, it took me a while to figure it out too, my palms were all sweaty thinking I derped my phone. And about the un-mountable SD card:
I had the same problem with my Nexus 10 when I was unlocking the bootloader, and all I had to do was actually do a format via Recovery (TWRP). Then I was able to boot into the ROM -- although I wasn't able to mount the Nexus 10 SD card still....so thats still a mystery. But I was able to get into the installed ROM

i tried that, and it failed.
i almost had windows format it, but i don't know which format type (FAT 32?)
and i'm still not clear if it will brick if i do
NEW EDIT: it doesn't brick, use default format type.
looks like i'm out of the weeds, thanks for all the quick replies.

The phone can charge in recovery mode and if not just power off from recovery and plugin the charger not usb. Also just try to flash the firmware again and this time edit the bat file and remove all the % signs then manually input the commands into the command prompt.

yes yes
Yeah yeah already, done,no luck

what I did was skip step 1 and 2, these:
mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img

[Q] Flashing rom stuck on erasing cache Nexus 5

My nexus 5 was stock when i did a factory reset and something wrong happened and it was stuck on the android guy with the blue sphere thing.
So i decided to try and flash the factory image from Google but it gets stuck at erasing the cache. I have done it both by flash all and by doing each step independently. And its always stuck on clear cache
I then tried the cwm recovery and wiped the cache and tried installing CM11. CM11 was stuck in a bootloop
then i tried TWRP recovery but the phone would not load into it.
Then i tried the WugFresh Nexus Root Toolkit to flash stock and unroot and the phone still gets stuck on erasing cache
Any ideas? What should I try next?

Flash stock recovery and wipe cache and leave it doing that for as long as it takes.

How long is reasonable?
I have waited 45 min in the past before losing patience

Could actually be a bit longer than that. Also, fastboot flash cache.img.on its own.

Thank You I will leave it running for a while and see what happens

It has been a little over an hour. How much longer should I wait?

Hard to say. Each time you interrupt it, you make it worse. Give it another hour. If that doesn't work, maybe try lg flash tool.

My mistake I might have interrupted it more then a few times yesterday. I probably made it fairly bad.

It has been erasing cache for about 12hrs should I give up on the idea it will do it and try the lg flash tool.

should rule out nand failure then. All I can suggest is send it to LG, if you've already tried swapping USB cables and ports.

Have you tried just formatting cache with fastboot? Tried multiple recoveries and wiping cache through them? If none of this works I'd bet your nand has a bad sector.

It can format erase and flash the cache no problem in fastboot it just wont do it at the end of the process of flashing a custom rom

I am having the same problem trying to flash to 5.0 or 5.0.1. It's to the point where Google says, "well, it's out of warranty, so send it to LG" and LG says, "send it to us and we'll tell you whether we'll charge you for a fix".
Pointer to the aforementioned "lg flash tool" - presumably different from the Google f/w at //developers.google.com/android/nexus/images - would be welcome.

[SOLVED] Stuck in bootloop even after flashing back to stock

Hey everyone,
I've been tearing out my hair for the past 34 hours (with the exception of sleeping). I restarted my phone yesterday and it got stuck in the boot animation, for hours.
I have never unlocked my bootloader, or flashed any custom rom on this phone, so I was really shocked when this happened. So I took to these forums, because lurking here usually solves all my issues (thanks awesome people), and flashed the stock image as recommended-> bootloop -> factory reset in recovery mode -> bootloop-> repeated this all night and today with multiple flashing methods (fastboot using flash-all and flashing individually, no dice.
I was wondering if I was out of luck, seeing as though my phone just randomly did this to itself, without prior tampering, or if there was something I could try doing. I haven't tried any custom recoveries as I don't really know how that would help me if I am willing to flash back to stock and lose all my data.
I am able to boot into fastboot mode and go to recovery mode, so this indicates to me that my hardware is fine, unless I am wrong
Thanks, I would appreciate all the help I can get

And you didn't receive any errors at all while flashing them individually? If that's the case I'd fastboot format each partition first then flash it. If that doesn't work you're pretty much out of luck. Just so where on the same page it would go like this:
Code:
fastboot format system
fastboot flash system system.img
Then just repeat that for everything.

Nexus 5 Stuck On 'Formatting /Data' After Factory Image Flashing

Nexus 5 stuck on 'formatting /data' screen after factory image flashing
Sorry for the long post. I just want to ensure I am providing all relevant history.
I have a Nexus 5 (Hammerhead) 32gb device, stock with no rooting. I mean, I had never done anything special on it ever.
1. Recently I started getting Google Play Store related problems, first 194 error and then couple of days back 495 (I think). After trying switching on/off, clearing cache and some other similar ways to fix this, I decided to do a factory reset :crying:
2. I backed up all my data, and followed the documented steps for factory reset. The phone got stuck on 'erasing'. After waiting for over 24 hours, I finally figured out that this 'erasing' is not going to complete, ever.
3. So I again did some research and figured that I should do a fastboot recovery. Tried that with no difference. Recovery again took me to 'erasing' screen.
4. Some more research and then I decided to flash a factory image using ADB. I was (and still am) a complete newbie, so first I figured out what was ADB and how to get to it. After completing the installation, I found out Nexus 5 factory images. There was no mention of which ones to chose, so I just picked up the latest one.
This is what I really followed:
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
https://www.youtube.com/watch?v=DRp5jJO34PE
5. Having learnt my lessons, I read the flashing instructions many times and also watched some videos 3-4 times. Once I was confident that no more information was going to be had, and the phone was unlocked (fastboot oem unlock) I went ahead with the flashing. I did it step by step - bootloader, radio and they recovery image. The last one failed.
6. I did some more research and found a method which told me to unzip the last image and flash the component images one by one. I did. Success! However, the phone did not reboot by itself as the guide said it would. So I tried to boot it manually.
7. I did not get the dead android with red exclamation mark. Instead, I got an alive android with gears whirring on its tummy and back. Pressing power + vol-up button told me that this was the 'formatting /data' screen. I am unable to get past this screen. I am supposed to get to a screen where I can wipe data and cache etc. But I cannot get to it.
8. I have tried to wait it out (16 hours) and tried flashing the images again. Ultimately, I end up here.
9. I am unable to find any answers on what to do if stuck on this screen. So this is the end? Is my phone bricked? Is there anything else I can try? Will trying TWRP way help or is that just another way to same failure?
I would appreciate if there is anybody out there who can help me get my phone working again, or point me to a thread which helps me do it. Thanks!

Just wait it took me 5 hours of waiting

Try flashing Android 4.4.4 and see if that will boot. If that does not work try installing a custom recovery like TWRP, and do the wipes from there.

Thanks. I was thinking of trying TWRP anyway. I will try this today.
How does one select which image to flash? Is it always the latest one? In this case, how do I know which one is Android 4.4.4, and why are you recommending this specific one? I had purchased this phone in 2013 Feb (I think). So is there any specific image to be selected or the latest one is always to be picked?

UPDATE: Flashing 4.4.4. did not work. I again got the 'formatting /data' screen again instead of the phone booting up. However, the formatting screen with the android with diamond circling in the tummy also has a blue line below, possibly a progress bar. It is not growing though, just there... sizzling. Pressing power+vol-up buttons shows me that this is 'formatting /data' screen.
Will try custom recovery from TWRP now.

Reboot your phone into bootloader and download latest hammerhead 5.1.1 from Google. Extract everything and then extract the images. First use these commands
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
Then fastboot flash everything including bootloader.
Use this as a guide http://androidforums.com/threads/guide-how-to-flash-a-nexus-factory-image-manually.706533/
Then after finished reboot phone and leave it alone it will boot right up in 5-10 mins no need to go to recovery. In future don't format partitions.

Thank you so much! Your post solved my issue. I wish I had this advice earlier!
First time it did not work, with reboot leading to a blank screen. Next time I following the guide completely, following the order in which different images were flashed. The phone went into boot animation for 5.1.1 and finally booted up, with all 32gb storage available.
Thanks again!

I'm really sorry that you are stuck in this mess. It is normal but more than 1 hour is way too much. I'm not sure about the causes, but you can try two more things and see how it goes. One is to use flash-all.bat script. If that didn't work then you can flash a custom ROM like Chroma and then try flashing the stock ROM.
