The first thing to do on xda is always do a search or browse through the different sections for your phone.

we need more info why can't you flash it back to stock what error's are you getting. more then likely you are trying to flash the wrong version of android and that is why it wont flash.
so we need
1. what error's you got
2. what model or carrier your phone is with

[Q] Dead in the water, unless a miracle comes along...

Well I decided to sell this Atrix HD I just recently acquired and of course because I have no luck at all not even 5 mins after posting the ad on craigslist I ended up potentially bricking it, sadly. I've spent the better part of the past 2 hours scouring threads and posts hoping for a solution but so far I've had no luck so I'll take this last step and ask if anyone might have any advice or solutions. Here's the situation:
- Atrix HD, originally with JB 4.1.1 on it (pre-final AT&T update, mind you)
- rooted with motochopper then bootloader unlocked with motopocalypse, no issues over the past 10 days or so that I've owned this AHD at all)
- was running CM11 nightly without issues (installed with CWM 6.0.5.1, had flashed several ROMs over the past 10 days including CM12, the Mexican retail ROM, and then back to pure AT&T several times, actually
- about 2 hours before making this post I listed it on craigslist and then used Myth Tools to go back to stock (stock being MB886_att-user-4.1.1-9.8.0Q-97_MB886_FFW-20-27)
- no issues with the flashing process, booted up as expected, worked fine for a few mins then I connected to Wi-Fi and grabbed the final JB update released by AT&T, when it finished I clicked "Install now" to do the reboot and install it
- rebooted into the install and seemed to finish ok, didn't glitch or error out in any respect
- somewhere in the middle of the final reboot after the upgrade it crapped out and then went into the bootloader loop to AP Fastboot (S) mode
- got the following error (which is known to a few other members in the past based on postings I located):
Code:
(typical info at the top of the screen)
Device is LOCKED. Status Code: 0
Battery OK
Connect USB
Data Cable
downgraded security version
update gpt_main version failed
failed to hab check for gpt_backup:0x35
failed to load GPT
CID Read Failure
Invalid CID status 0x69
No SP partition found
Fastboot Reason: Invalid GPT
usb connected
As stated, this AHD was bootloader unlocked without any issues but for whatever is now showing as LOCKED. The thing that concerns me is that if I use fastboot devices it doesn't show the proper info as it used to (the typical TA00etcetcetc model number) - it's showing an 8 digit alphanumeric number I've never seen before so that's a big red flag right there.
I've attempted every process I can locate so far and had zero success at all - only one single fastboot command gives me an OKAY message and that's fastboot oem fb_mode_clear. Every other fastboot command offers up a FAILED (remote failure) error, all of them and I've tried pretty much all of them.
I cannot flash anything to the AHD it seems so I'm guessing that means it's 100% "bricked" in the sense that it's powering up, can be seen from the PC/laptop using fastboot devices, but that's it just not actually there at all for whatever reason.
I've attempted to use 2 different laptops, 1 desktop, multiple various USB ports, cables, you name it I'm pretty confident I've attempted to use it in some respect and still nada, zip, zilch, nothing has come from my efforts. If it's totally bricked then so be it, I'll live, but I keep holding out hope that something I missed will help but it's starting to look like this is beating a dead horse now.
I've attempted using RSD Lite to push the Mexican retail ROM to it (with the edited xml file), the AT&T retail ROM, etc - I can't locate any FXZ files at all so that might still be an option but I simply cannot find any of them if they exist.
So apparently for whatever reason the final JB update pooched this device (even in spite of it not doing it in the past week when I rolled back to stock at least 3 prior times in testing). I'm suspecting - but can't say for certain - that potentially the CWM 6.0.5.1 which I just installed like 2 days ago could be the culprit here; previously using 6.0.4.4 I had no issues whatsoever and that is the only variable that's changed in my flashing process that I can recall.
Anyway, that pretty much covers the situation - if anyone has any advice that might bring this AHD back to life I'm definitely interested in hearing it. I don't have JTAG hardware, don't have a factory cable (if one is required), don't have anyone in the area that does that I'm aware of, etc. Basically if I can't get it resolved on my own then it's a dead device I'll toss in a drawer till that miracle comes along...
Thanks for reading, regardless.

Nothing will flash to the device which is the biggest issue of all; if I could flash the gpt_main0.bin file I'd be getting somewhere (since as I understand it that sets the partition layout for the partition img's that will follow in the flashing process).
As stated, the only thing that works in terms of a fastboot command is fb_mode_clear which gets an OKAY response (although fb_mode_set does too, actually). But no other fastboot commands are functional - I tried fastboot -w and get:
Code:
D:\motopocalypse\motopocalypse>fastboot -w
erasing 'userdata'...
Invalid partition name userdata
FAILED (remote failure)
finished. total time: 0.140s
so then I try:
Code:
D:\motopocalypse\motopocalypse>fastboot erase userdata
erasing 'userdata'...
Invalid partition name userdata
FAILED (remote failure)
finished. total time: 0.141s
and so on and so forth. No attempts to erase data nor write it in any manner are successful. RSD Lite basically is useless as well (pic attached below). Since I can't write any data to the device at all then as I've said, it's dead in the water unless a miracle comes along. Was looking at eBay in the hopes of finding a busted/broken AHD (damaged glass, etc) and swapping the mobo from that one back into my housing but they're a bit expensive for busted ones at the moment, guess I'll just keep hoping for that miracle.
I've never used a JTAG or factory cable on any devices I've ever owned but I have to wonder if such a contraption might get this back to a working state. Suppose I'll need to do some research into things - I tried to contact Motorola about it but of course since the AHD is so old now and I'm not the original owner, even though I registered the device in my name they won't honor the warranty without a proof of purchase (meaning the retail one years ago when it was new).
Out of over 100 smartphones and other devices I've owned over the decades this is the first time one's actually up and died on me and go figure: it died when doing an OTA update on a clean stock ROM installation.
How ironic...

Yep, it's all the same basic process whether it's done scripted or manually, same result: as stated, nothing will flash to the AHD and kicks back the same error each time (partition errors). I have no idea what that damned OTA did but it totally wrecked the whole thing...
Even tried doing this under Linux - the issue isn't with fastboot or the builds, it's with the AHD itself because it's not writing anything I'm trying to flash to the device and I'm confident it's because the partition structure is pooched for whatever reason.
I'm still wondering about using a factory cable (will have to buy one off eBay I suppose) will make any difference at all, I just have no experience using them and if the phone isn't flashing/writing data to the device because the partitions are pooched, I can't imagine using a different albeit specific cable will make that much of a difference.
Bleh... I hate it when crap goes wrong, I really do.

FAILED (data transfer failure (Unknown error)) when trying to flash anything to phone

I have S-ON and a non-HK phone with an OS of 2.16.651 I believe. @Sloth tried to help me but to no success, so I'll try to see if anybody else can help me figure out the issue.
Basically, everything works up until I actually start to flash the phone. It gives me this error:
FAILED (data transfer failure (Unknown error))
There's a bit more to it, but that's mostly unrelated stuff (the command and blahblahblah).
I've tried 2 different computers and different ports on all of them. I don't have any other USB cables for my phone available, but this one works with my PS4 controllers finely so I'm guessing it should work fine.
If someone could help me and anyone else with my luck in the future, please answer. I don't want to have to resort to a store as I have no money and the store is quite far. Thanks!
EDIT: Something else to mention, there is no firmware on this device and only has an accessible bootloader and recovery. I currently have the bootlocker relocked. I had ViperOneM8, although uninstalled after realizing I had no access to WiFi (I ignored the disclaimer :c). I don't have a SIM card as this phone was given and I didn't buy it myself from any carrier, I have no service. Some other stuff to mention is that I verified the MD5 of the firmware and it was not corrupt, I had the proper working drivers as I checked if it found my device, and that's it.

So no RUU works? Try using this fastboot version... simply unzip it and copy the files you want to flash into the resulting directory and run your commands from there.

Battery drain 10%/h and vibration not working

Hi everyone,
I tried to install the CM 13 in my moto X 2014, but I forgot to install Gapps before rebooting my phone. So I had to flash android 6.0 and try all over again. I dont´t know if my mistake in the procedure has something to do with the problems below.
I realized that my phone is not vibrating anymore and the battery drain has been drasticaly increased, like 10% per hour while in idle. When I use my phone (whatsapp, chrome etc) the battery drain seens to be like in idle (no apps running on background).
A full charge takes 4 hours with normal charger or 8 hours if connected to my computer.
I Tried android versions 4.4.4, 5.0, 5.1, 6.0, NX 10.1 and CM13. I don´t know what to do. Motorola assistance said the motherboard is the source of my problems just because i unlocked my bootloader.

I feel like it's possible that you downgraded the bootloader in the process, and that could be the only problem. In that case flash this to get stock, as it'll be the latest firmware.

Use the instructions from this thread.
http://forum.xda-developers.com/moto-x-2014/general/guide-return-to-stock-official-status-t3274121
Also check the cable you're using to charge the phone, with regards to the slow charging.
If there's still things wrong afterwards it is probably a hardware problem. Good luck.

Sorry I did not reply you earlier, canaval holidays... back to real life today.
I tried what you suggested but without success.
When I try to execute "fastboot flash partition gpt.bin" it fails (I´m not at home right now and I don´t remember exactly the message I got), but all other commands runs like expected.
I saw this thread " forum.xda-developers.com/moto-x-2014/help/managed-to-screw-phone-bootloader-to-t3309241?nocache=1 ". It has a command that in the other you suggested has not.
"fastboot getvar max-sparse-size"
What is it for?

The error for the flash partition may be a result of using fastboot and not motorola's own fastboot. I've attached a motorola fastboot in a zip, so you can try again using that fastboot file. The extra commands don't help with anything really because they do not affect the flashing of partitions.
The fastboot getvar command is literally "get variable", so in that case it would just return the maximum file size that can be flashed I believe, and in case you were wondering:
fastboot oem fb_mode_set - Makes the phone automatically reboot into bootloader mode.
fastboot oem fb_mode_clear - Just resets the above commands setting back to normal booting.

The message I mentioned when I execute the command "fastboot flash partition gpt.bin"
sending 'partition' <32KB>...
OKAY [ 0.030s]
writing 'partition'...
<bootloader> Preflash validation failed
FAILED <remote failure>
finished. total time: 0.130s

Nevermind... I was trying to flash an old gpt.bin.
I guess that's the end, I give up. I don't know what to do, nothing works.
I'm thinking of buying an used device with broken screen for 1/3 of the price of a new one (350 reais, almost 100 dollars), disassemble everything and assemble only the motherboard in my device.
I really appreciate your help but I guess I need the Blanckflash and I searched and no one has it because motorola did not released for us.

yes the newest drivers are installed. It shows up in device manager as "MOT Single ADB Interface". I can also detect it in fastboot, though most commands won't work.

i had a similar kind of problem on my ghost. Firmware crash, due to which phone was stuck at the bootloader. No recovery nor did any fastboot worked at that time. I referred this and this. It worked for me.

when following the second link steps i get stuck at step 8. Im not sure what he means by click on the device. does he mean the 'Mot Single ADB Interface' device? i clicked properties on that then i clicked update and i selected the folder where i kept the signed sys files. there was nothing about QHSUSB_DLOAD as it said in the tutorial though. anyway afterwards there was no port called Qualcomm HS-USB QDLoader 9008 so i couldn't get a portnumber to continue the process.
The other link you gave i assumed id go to Moto X BE\1_Repair_Boot (RSD Lite)\1060 and flash the gpt.bin and the motoboot.img but i got this error:

I'm in basically the same situation with my XT1060 Developer Edition. Tried a long list of fixes, none has done the trick. All I have available is the fastboot menu. Phone won't boot into OS, won't go into recovery, hasn't accepted any flashes or erases. This happened because after downgrading to 4.4.4 I allowed an OTA update to 5.1. Phone rebooted and hasn't left the flashboot menu since. I, too, am looking for any help I can get on the matter.
Just like you, I tried that trick involving the fancy drivers, but my phone shows up as "Mot Single ADB Interface" in device manager, so that fix doesn't apply. If my phone reported as QHSUSB_DLOAD in device manager, it would be a different story. Though my phone was rooted and unlocked before downgrading to 4.4.4, at this point it's locked (happened without my knowledge), which I believe is why I can't reflash a recovery image.
It seems pretty clear to me that the phone has either an absent or corrupted partition scheme, as gpt.bin won't flash AND my phone doesn't acknowledge the existence of partitions. I suspect my phone began writing the 5.1 OTA update before erroring out, thus leaving me in a limbo mode halfway between 5.1 and 4.4.4. If anyone out there has experience with this seemingly unique brick situation, I would appreciate it. OP, good luck with your phone.

I'm in basically the same situation with my XT1060 Developer Edition. Tried a long list of fixes, none has done the trick. All I have available is the fastboot menu. Phone won't boot into OS, won't go into recovery, hasn't accepted any flashes or erases. This happened because after downgrading to 4.4.4 I allowed an OTA update to 5.1. Phone rebooted and hasn't left the flashboot menu since. I, too, am looking for any help I can get on the matter.
Just like you, I tried that trick involving the fancy drivers, but my phone shows up as "Mot Single ADB Interface" in device manager, so that fix doesn't apply. If my phone reported as QHSUSB_DLOAD in device manager, it would be a different story.

For both of you.. @RandyThor and @OrlandoAlex check thread after 12hrs.. i have something for you which may hopefully fix thay issue.

I'm in the same boat. At least I've finally learned why I always refuse OTA updates (until now it hadn't really dawned on me that I had to blankflash because I downgraded after having updated official firmware).
A solution would be much appreciated, as nothing I've done has worked to this point. I'll read more on here to see whether someone has already posted a solution, and I should be able to check back on this thread in a couple of hours.
EDIT:
It does not look like there is a common solution, from what I can tell in the Q&A. Will search elsewhere next.

@Salik Iqbal, you've done it! Can you tell me exactly why that worked? Which version of the bootloader was that? Also, THANK YOU!
