Hi, maybe you could give us some more clear infos of what you have done exactly...
Why you want to unlock your bootloader?
Try to reflash an original firmware with RDS and if you want root use "TwerkMyMoto"...

you dont need to unlock the bootloader to reflash your original firmware via RSD-Lite!
Follow this to install stock rom: http://forum.xda-developers.com/showthread.php?t=2643779
I got yesterday also an Update-Information from whatsapp. I will NOT install until it is confirmed as non-bricking. Thx for your info/warning!

i Just try using RDS Lite but in the step 4 the reboot never boot and the flash fail
Can you enter recovery? Selecting it in the fastboot menu, what happens? In RSD does it flashes and only in the reboot portion it fails? Did you try to turn it on without the external SD card?
As far as i can tell the device is trying to use the linux discard command, it seems like a wipe that gone wrong.

Hi thiagomtl let me answer your questions, when i try to enter in recovery the phone gets stuck again with the motorola boot logo and after a while returns to fastboot mode, and when i try to flash whit RSD in the step 4 that is reboot, on the phone stays a command that says Rebooting Droidboot and nothing happens, and yeah when i do this operaions i always remove the sim card and the sd card , so if you now something ill appreciate a lot it!!
Try those in fastboot:
fastboot erase data
fastboot erase cache
After try RSD again.

I already do that but im still getting this error
BLKDISCARD ioctl /dev/block/mmcblk0 fail
I am guessing that is an error in the emmc, the problem is that i don't know how to fix it
Victor, I'm having the exact same problem. Did you find any solution?
I'm having the exact same problem!!
What I did was that when it gets stuck waiting for reboot I did reboot it manually into fastboot mode again and process continues. The problem is that it gets stuck again when flashing the system partition. Bootloader won't let me erase the partition nor flash it.
Tried unlocking the bootloader and:
(bootloader) BLKDISCARD ioctl /dev/block/mmcblk0 fail
(bootloader) Erase userdata fail
(bootloader) General Unlock failure!
(bootloader) OEM unlock failure!
FAILED (remote failure)
finished. total time: 9.666s
Is there a way to know the original provider of the phone, to make sure I'm using the correct firmware?

You got a serious bug. There is a huge change your device is now broken beyond repair, i hope not. But can u access the recovery partition? Can u flash a custom boot image?

I also having the same problem after force power on/off when hang during TWRP format. Now the unit in hard brick. If able to force temporary boot into recovery using ram instead of rom, might have some hope. But it looks like no way to boot from ram. :crying:
same prob as victor gtz
fsd lite freezes at step 4, unlock bootloader doesnt work and so on and so forth, so anybody got a clue what to do?

Same problem here, rsdlite didnt work for me and the bootloader cant be unlocked with the same error message. Theres any way to solve this? i read once that you can recover the android from the dead even if the boot isnt working, maybe thats not true at all.....

It's true, but not for all devices. And if u have the above, the nand memory is broken. That can only be repaired by some kind of powercycle on chip level or anything.
Right.
So, I was opening youtube on the last version of CM 12.1. No xposed, stock kernel, XT1068 model, when all of a sudden the phone stopped working.
Youtube wasn't opening. The phone was stuck on the home screen, all I could do was just press the home/back/recent buttons. Even long pressing power button to reboot would just take me to the power menu but Wouldn't allow me to do anything.
So in the end I long pressed the power menu to force reboot the phone aaaand... stuck on the boot logo. Not on the bootanimation, on the Motorola Bootlogo.
Managed to get to fastboot mode, tried to go to recovery, but after the twrp splash screen It would reboot to the splash screen again.
So i decided to mfastboot the original firmware. Who knows? maybe something got corrupted on cm.
Now, mfastboot is giving me weird errors.
flash partition gpt.bin gives (bootloader) Preflash validation failed
flash motoboot motoboot.bin gives FAILED (data transfer failure (Unknown error))
flash boot boot.img freezes everything and i need to reboot it to try and get to fastboot again.
Anybody knows what I should do? I'm kinda desperate here...
Thanks in advance. Peace.
(by the way, latest motorola drivers, just so you know...)
EDIT. Also, on the phone, it says
"hab check failed for primary_gpt
Failed to verify hab image primary_gpt"
Hope I can help
Are you flashing a gpt.bin from a previous android version? You cannot downgrade gpt.bin or motoboot.bin so the error is normal. From what firmware version is the boot.img you are flashing from? Try downloading this twrp recovery img from here https://dl.twrp.me/titan and
Code:
fastboot flash recovery recovery.img
or
Code:
mfastboot flash recovery recovery.img
Then you can try flashing any rom like this AOSP one http://forum.xda-developers.com/moto-g-2014/development/rom-android-source-project-t3123109
Hope this helps. I understand how hard it is to have a phone that won't boot.
Maybe you should try to place the stock rom 4.4.4 and then upgrade to 5.0, with 4.4.4 rom the GPT will have a downgrade and then you update the GPT putting 5.0

You cannot downgrade gpt
Well I somehow managed to reboot into recovery, but the great problem here is that it won't mount \data.
Now, maybe all I need is to reformat \data cause it got corrupted, but since TWRP won't mount it, I can't do much about it.
I found on another thread this command
adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
reboot
Which apparently formats the data partition of a phone. I suppose I'd have to change "ext4fs" into "f2fs", but I'm too scared to actually try it out.
Also because I don't know whether mmcblk0p8 is the right block for our data partition.
Jeez, I hate this.
Thanks for your help guys, but I don't think flashing recovery again would help. Nor downgrading, but I'll think about it.
EDIT.
Magic, just magic. After hours of tinkering I did EXACTLY THE SAME THINGS and now it's working. Restored the stock Rom and I'm off to install CM again.
Sorry guys and thanks so much!!!
I tried to upgrade from Android M preview 3 to 6.0 Marshmallow using the flash-all.bat.
There were error messages and the phone would not boot into recovery.
I went back to fastboot to flash files one at a time.
When I try to flash bootloader it fails with the "Preflash validation error" message.
Is this telling me that I can't flash the bootloader because it was already flashed during the (unsuccessful) flash-all.bat?
Can I flash the other files to get the phone back to working order?
Hi, I have the same issue. Were you able to flash the new bootloader?
I've read and heard from several people that the flash-all.bat doesn't work correctly. I'd recommend flashing the .img files separately.
Long story short, woke up with my N6 stuck at the bootloader screen and cannot do anything at it. I can only see my serial number and if I try anything else, it reloads bootloader. I am trying to flash back to a stock 6.0.1 image, however I keep getting this error while trying to do so.

I have tried Nexus Root Toolkit, tried flashing all and tried flashing each image one by one but I still get this "(bootloader) Failed to flash partition FAILED (remote failure)" on all attempts. Phone does show up if I try fastboot devices, and I have tried this on two different computers. Device is also unlocked as well, and I even tried flashing older versions of Lolipop but they all give me the same error. Drivers work fine, and I have everything up to date in terms of bootloader and Andriod SDK. I am starting to think that there is physical damage inside the phone, however I do not know how or why this occurred randomly. Any help would be awesome, as I am very new to flashing images onto my phone and frankly I am 99% sure that my warranty is out, and I really don't want to pay $175 cost .
You can try to use minimal adb and fastboot drivers, unpack for example latest npreview 5 factory Image into same folder and flash each .IMG step by step with cmd window, i always flash this way, if everything else fails.

I did not have TWRP installed on my phone since I had it completely stock and unrooted, so I tried installing it in the hopes of that some chance it would work and I could access it.

Bootloader is unlocked i guess, may your Bootloader is messed up, did you try to flash only one Factory Image ? Corrupt Download possible ?
What happens if you try unlock command
Try to flash the latest full ota with these steps.
https://developers.google.com/android/nexus/ota
Since you already in the bootloader, select recovery and fpllow the steps from there.

Any image I even try to flash I get the error with, no matter what order or which one I pick. I redownloaded the image again and still nothing, so I don't think it's a corrupt download. What is the unlock command? Sorry for being a noob, never heard of it since all my knowledge is from reading tons of flashing guides on the internet lol.

Alright, I downloaded the OTA file and got the process to about 47% when suddenly I keep running into the error of "E:Can't open /cache/recovery/log" then followed by more things it can't open. I tried the OTA twice and it gets stuck on that same exact spot. I tried the wipe data/factory reset option from the recovery mode and I get a similar error of "Can't mount", "Can't open", "failed to mount" the recovery log. It seems like there is a problem with the recovery log files (or the folder) on my phone, but I have no idea what that means. I will mess around with some more and try Googling the source of error, but thank you for the help.
fastboot oem unlock
With this command you can unlock your Bootloader, better read here
first http://forum.xda-developers.com/showpost.php?p=56938530&postcount=1 , if have 47% done, may you can use twrp now. Good luck
Did you try the erase function from bootloader that may or may not help??

Oh yes, my device has already been unlocked from the start so that wasn't a problem. I still get the same error when I try to flash anything, including TWRP which means I have to install the OTA. The problem is a get a separate error when I try to install the OTA, which the only solution being to flash my device (or at least that is what most people have been saying when I googled the can't open cache recovery error) so this is a giant goose chase which leads me back to the start :/. I will keep trying however, I refuse to give up after going this far!

Should I try fastboot erase cache and then fastboot format cache? Would refresh the cache on there? I only just learned the erase command so I am not exactly sure what I should try.
Should be able to erase any partition if your unlocked

I don't know the commands to erase everything from the bootloader but I would try this:
Flash latest twrp and boot into recovery.
Assuming you don't care about anything that's on the phone, go to advance wipe and wipe EVERYTHING lol... reboot into bootloader and try to flash everything from scratch. If this doesn't work, I'll guess your phone have problems.

I get the same failure error while trying to format and erase, so I am guessing something is really wrong with my phone or the bootloader is messed up beyond repair. I guess it could be the cable I am using as well, that is one thing I did not take into factor so I will try with another cable if I find a spare. Flashing might be beyond my solution at this rate though... Thanks anyways for the help.

Yes try another cable, if it stops at 47%, the Bootloader should be replaced. May try everything without simcard, don't ask me why, i read something similiar in a Moto forum
fastboot erase recovery doesn't help ?

I tried it with another wire and nothing changed, and then I tried taking out my sim card and trying it.... and it worked! It flashed everything normally and loaded up just fine. I don't know whether I should be furious or happy but thank you and everyone who helped. Who would have known just taking out the sim card could have saved me 2+ days of stressing and trail and error. Once again thanks, you really saved me lol.
You're welcome, nice your phone works again !
Don't forget to activate oem unlock and debugging in the Developer options, and flash twrp, so maybe more save for upcoming problems
skipsoft android toolkit maybe help you in future
So my mom's phone started bootlooping yesterday. I've tried a couple of things to recover the data already, but nothing seems to work.
It bootloops at the "Optimising apps" part after the boot animation, is there for a couple of minutes and then reboots and starts doing it again.
The bootloader is locked and USB debug is turned off, so I can't access adb. I can't just unlock the bootloader, because as I already said I don't want to lose the data in there.
The phone probably has the latest update there is available installed, so most likely it's at 6.0.1 I think? and I think it's region RETAILDSDS (she bought it in Spain and it does have dual SIM).
Things I've already tried:
Booting into the stock recovery and trying to use adb, but it doesn't recognize the device (predictably so)
Flashing a custom recovery, I can't seemingly do that without unlocking bootloader first
Flashing a stock 6.0 firmware without erasing user data, gives the following error in cmd when trying to flash the system partition:
Code:
"writing 'system'...
(bootloader) Invalid signed image
(bootloader) Preflash validation failed
FAILED (remote failure)"
and in the phone it says:
Code:
cmd: flash: system
version downgraded for system
Invalid PIV signed system image
