I have tried everything I have read on here and I cant seem to flash recovery. I used pwnmymoto to gain root when I first received my moto x. When the camera update came I thought I unrooted and flashed back to stock becasue I was able to get the OTA. Yesterday I could not install the OTA 4.4 because it gave me a error sign. I tried to flash recovery using fastboot but everytime now matter what I do this shows up:
colins-air:Android Tools colinj22$ ./fastboot flash recovery recovery.img
(bootloader) Variable not supported!
target reported max download size of 805306368 bytes

OKAY [ 0.798s]
writing 'recovery'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 1.848s
colins-air:Android Tools colinj22$
Can someone please help me. I am fairly new to fastboot and I am on a Mac and I have read everything in these threads and nothing seems to help. Can I erase everything and somehow start from scratch?
Thank you all!

try using a different fastboot besides the one you are using. also make sure you are trying to flash the right FW version. you can't downgrade FW so it needs to be the FW version that is currently on the device.
try the second link in the OP of this thread for a different fastboot

Flashing recovery requires a unlocked boot loader, you're obviously on Verizon and unless you have a DE moto you can't flash recovery due to your boot loader being locked

EDIT 3: Okay, just flashed a new kernel and the WiFi is working now. Must have been the stock kernel for some reason.
So all problems solved now
EDIT 2: Succesfully flashed the ROM, but unable to connect to Wifi. When I press the on button, it switches on for a second and then switches off again. Any idea guys why?
I've been trying to flash the stock ROM, but can't because as soon as I begin with the first step i.e fastboot flash partition gpt.bin, the following error is displayed- fastboot preflash validation failed.
Now I've been reading up on the forums here and a some have said that this error occurs when someone tries to downgrade. But I'm on the latest build and I don't know why this is happening?
Just so everyone knows, I'm unlocked and rooted.
Please, I need help since the ROM I'm on, which by itself is stock, is pretty much not working.

You can ignore gpt.bin and motoboot.bin. They won't flash if the same or lower version. Not a problem. Just continue flashing the other files.

Okay, thanks man, I successfully flashed the ROM. But now I have another problem. I'm not able to switch on my Wifi. When press the on button, it switches on for a micro sec and then switches off. Any idea why?
Don't know. Maybe a reboot. After that I would wipe dalvic, cache and data?

I did better, a factory reset. Nada.
Would flashing a different kernel help?
Did you do a
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
This is a wififix for the kernel

Oh I didn't know that this was a wifi fix, but yes I did perform the above steps as well.
But anyhow, I flashed a new kernel and it did solve the problem.
Thanks

Didn't you read anything of the previous posts?
If you've unlocked your bootloader, and getting these errors, you can safely ignore them. Just carry on flashing the other files.
Carried on
I did carried on with the fastboot steps but I get this "UTAG "flashfail" is configured as fastboot" and I'm still stuck in Bootloader.
How do I change the Kernel?
Oh yeah, I updated to Lollipop about 20 days ago, worked fine until a few days back and suddenly I get these strange errors. What could be the cause though?
Hello Guys im attempting to install TWRP 3.0.2 on my Moto X 2nd Gen 2014 with Android 6.0 Official but im getting an error in my command prompt. I have already attempt to request and an unlock code for unlocking the bootloader but motorolas site state my phone is not authorize for unlocking it. Does my phone need to have boot loader unlocked to be able to follow this step? Im pretty much attempting to install this recover to be able to root following this method: http://forum.xda-developers.com/moto-x-2014/development/root-root-moto-x-2014-android-t3249105

Yes, the bootloader needs to be unlocked to install a custom recovery (which is stated prior to the first step in the thread you mentioned). At one time there was an"unofficial" bootloader unlock that you might look into.
Good evening guys...
I have a Moto X 2nd gen (XT1097) with Stock Retail BR Rom and it was working like a charm till this morning.
I received a notification of an OTA Update (security patch) and I wanted to patch the phone...
I know a rooted phone (like mine) could not receive OTA Updates, so I flashed stock rom again with RDSLite like I always do.
The problem occured when I try to root it... I picked a wrong file to flash with the TWRP and cel got stucked in the boot logo.
When I try to flash the Firmware stock 6.0 in the RDSLite, It returns a error like that:
Code:
fastboot flash partition gpt.bin

I asked a friend of mine that have the same device and the version of his bootloader is 60.18 (sha-3b3b501 ... )
my bootloader, after I fuc*ed the device is 60.00 (sha-130760b ... )...
I can still turn on device, can flash the firmware if I erase gpt and motoboot lines from flashfile.xml but I cannot OTA and root, got some errors!
Anyone knows something about that? Can I try to downgrade to solve? Anyone knows this bootloader version???
Sorry about english...
I tried every ROM (4.4.4, 5.0, 5.1 and 6.0) and all of them returns the message "version downgraded for primary_gpt"... FU*K this SH*T!!!!
My bootloader is at 60.00 version and I really need to put the 60.18 version... How to do that?
I have a Motorola Moto G 4G (2nd gen)
So I'm trying to install my stock 6.0 rom on my phone, I have fastboot, adb and the drivers installed my rom(i think its the correct one)
(XT1072_THEA_RETGB_6.0_MPB24.65-34_cid7_subsidy-DEFAULT_CFC.xml.zip)
I have all the software needed installed but whenever I try to flash someing it says this:

I have no I dea what to do atm I tried different guides but I just keeps getting stuck at the "Your bootloader unlocked......" screen you get when you unlock your bootloader.
I followed serveral guides but nothing seems to work and I'm to the poin that I dont even wanna root just a working phone..
If any of you guys could help me out that would be great because I've been trying thiis for 5 hours and no succes
If you have any questions feel free to ask me, I'm available on discord and ts if needed!
THanks I advance
Have you flashed the rest of the firmware. You can ignore that bootloader message.
