How to Re-Lock GPE?

Like an idiot i bought a GPE and didnt realize its not 4g, and has issues w/ tmobile. Then unlocked it soon as I got it.
How do I re-lock it? The command does not seem to work
I am always Given "Failed to validate system image"

Anyone? Beuller?

You'll have to first start by issuing the command 'fastboot oem lock begin' while booted to the bootloader.
Then find the procedure to flash the stock firmware to the GPE and do that.
Then after that is finished issuing the command "fastboot oem lock' and it will relock your bootloader.
However once the bootloader is unlocked it is not set back to 'locked' once relocked; It is set to 'relocked', so they could possibly still tell the difference if they are paying attention.

I tried that, thats when I get the error I mentioned above.

You'll probably need to use mfastboot.exe instead of fastboot.exe. Which one are you using?

mfastboot.
Is it possible it has to do with the fact it got the 4.4.4 update?

Any help would be great. If not then I'll just try and resell it.

Someone must have something I can try.

WHen i to to restore I get this message on these files
mfastboot flash partition gpt.bin - Version downgraded for primary_gp
mfastboot flash motoboot motoboot.img - Version downgraded for tz
mfastboot flash boot boot.img - Version downgraded for boot

I'd love any input at all.

guess not

[HELP] XT1563 Bricked after trying to root it

After tried to root my device without the assist of PC (only using apk), my device only starts on AP Fastboot Flash Mode (Secure).
I downloaded the brazilian firmware, tried to flash it but I can't.
Was getting this ERROR: "(bootloader) Preflash validation failed".
My bootloader is locked, so I tried to unlock it following the Motorola's guide. Got my device ID via fastboot, copy and paste on their site and requested the unlock key.
Then again, when I use "fastboot oem unlock CODE"
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
finished. total time: 0.016s
The problem is that I can't pass trough flash mode screen.
I've been reading some threads over here, and one guy which had his bootloader locked on XT1563 tried to flash the Canadian firmware and didn't get any error, then he was able to fully unlock his bootloader and after this he was able to flash the Brazilian firmware.
I didn't try to flash the Canadian firmware yet. How risky is this? There is another way to unlock the bootloader?

If you flash the right firmware for a locked phone (model and version), it won't give the prevalidation error. Then it can boot again and you can turn on the OEM unlock, and unlock the bootloader.
Try to use the right firmware for your phone.

I don't believe it is possible to root without first unlocking your bootloader (which will factory reset your device). What apk were you attempting to install?

I'm a real noob at this issue. I tried to root with Kingroot. I took the device to the Motorola Tech Support in my city yesterday afternoon and it is ready to pick up.
Thank you guys for helping me :good::good::good:

If you really want to root, you need to follow these instructions. Although you can use the latest version of TWRP, do not use any other version of Supersu except v2.62-3. Any other methods will most likely soft brick your phone.

Boys, is not difficult, not just fiddling around to fix it.
Motorola install drivers
Install ADB and fastboot
Looking for your stock rom here: " github dot com dash motoxplay dash stock dash releases " for example.
Saddled with fastboot Tooda the rom (eye, if downloaded from out there commands, you may be wanting to them upload any image rom, this drove me crazy to me all one day until I realized I was missing two sparsechunk).

On the subject battery, the XT1563 charge the batt when it is in this mode, we just have to leave it connected to the charger and is loading very slowly.
On the bootloader issue, I have LOCK, and may do so without problems because they look the same version of rom that he had.
About not having DEPURACION USB, I did not have it on, and yet I could do it.
My stay in Fastboot mode I when installing the app Kingroot, and turned off the phone and start no more.
In this way it is solved, 100% sure I did not do myself. Do not try other methods like TWRP or things like that because with locked bootloader will hit the wall every time.
Anyone who needs a hand, ask or send mail.
Sorry if he had been resolved, but it was a big achievement for me, so I leave the info. I cost a lot to buy the cell phone and had ****ed the other day.
Regards!
(Sorry, its googletranslated, im from argentina)

Yeah, what ever @jonatandirocca1 said is right
i also once faced the problem of missing sparse file but after flashing every file you can make your Phone revoke
if you want to install STOCK FIRMWARE , you dont need to unlock bootloader, you just need your phone detected in ADB

Restoring Moto G (2nd gen) after failed rooting

Hi all,
I could really use some help on the following, and any advice would be greatly appreciated.
I wanted to root my Moto G (2014, 2nd gen, dual sim) in order to use the RAM more flexibly. Unlocking the device was no problem at all. However, when I initiated the rooting process, the trouble started. I first tried superboot, which did not work, but also did not destroy anything. Then, I switched to using TWRP and the supersu image (I found the info on here). TWRP worked fine, but after initiating the installation of the supersu image, the phone got stuck in a boot loop -- it stayed on the unlocking warning page and would not boot up anymore. I figured out a way to get back into fastboot (also by looking through the forum here, thanks to you all!) -- by pressing the power button until the screen switched off, and then pressing the Volume down button as well for a few seconds.
However, none of the recovery methods I found in other threads worked (I tried deleting the cache etc. through various methods, but the loop persisted). So, next, I attempted to use the method I found on droidviews.com to restore the phone to a working status (any working status would do at this point).
Since I was not able to access the debugging options anymore, I did everything except the initial 'adb reboot bootloader' command. Here is the list of commands:
mfastboot oem lock begin
mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin
mfastboot flash boot boot.img
mfastboot flash recovery recovery.img
mfastboot flash system system.img_sparsechunk.0
mfastboot flash system system.img_sparsechunk.1
mfastboot flash system system.img_sparsechunk.2
mfastboot flash system system.img_sparsechunk.3
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot erase cache
mfastboot erase userdata
NB I am doing this on MacOS, so I used the osx-fastboot command instead of mfastboot. Up until 'flash boot boot.img', everything worked, but when I tried the 'osx-fastboot flash recovery recovery.img' command, I got the following error message in the Terminal window:
(bootloader) Preflash validation failed
FAILED (remote failure)
And the error message on my phone reads:
hab check failed for recovery
Failed to verify hab image recovery
What can I do at this point? Since I followed the instructions as closely as possible, I also used the 'osx-fastboot oem lock begin' command, and now my device indicates that it is locked. Did I wreck my phone or is there any way out of this at all?
As I said, I would be most grateful for any advice at all. If you need more information, I am happy to provide it.
Thanks!

I am still looking for ways to get the phone into any sort of working order. Do any of you have advice on this? Is it possible?
I ran Lollipop on it before it crashed, if that is helpful information.
Thanks

After connecting the device to a Windows 7 PC, I can confirm that the Windows system does not recognize the Moto at all, so it appears that the method in the main thread on unbricking & restoring Moto Gs back to 4.4.4 / 5.01 would not work either, right? Is there anything else that I can do?
If anybody were to give me even the most spurious bit of advice, or some feedback on how I should go about finding a solution on the forum (I am trying my best, but might not have observed all the etiquette etc. out of ignorance), I would be tremendously grateful.
Thanks

Here is the solution a very friendly user -- inFiniTyz_Z , many thanks!-- on here pointed me towards:
If a bootlocker is unlocked and then relocked, as was mine, it is entirely possible to unlock the bootloader again. One needs the unlocking key from Motorola and the command
fastboot oem unlock UNIQUE_KEY
With the bootloader unlocked, I was able to flash TWRP again, which of course helped tremendously.
After this, I managed to install a Brazilian stock ROM -- the German one I would need did not work, but I will look for ways to get the phone to work regardless. At the moment, Android is up and running, but it does not connect to the network (because of the Brazilian settings, I guess). I might switch to CyanogenMod anyways.

Preloader Validation Failed Although Bootloader Is Unlocked, What Gives? Moto G Pure XT2163-4

Have soft bricked phone. Moto G Pure Ellis XT2613-4 I was going through the root process and forgot to fastboot flash boot boot_a then boot_b instead I just tried fastboot flash boot boot.img
been awhile since I tried to root a phone forgot a bout the commands. When it was stuck in the bootloop I thought maybe I flashed the wrong image and tried flashing dtbo.img (lol). That just made it go into a faster bootloop. Im running linux so I cant really download and use any of the fast fixes like Motorola family rescue without having to do a lot of extra work with emulators so I was trying to find a fastboot solution since I know there has to be one.
Anyway I am trying now to flash with flashall -w from stock ROM and I'm getting cannot find or read android-txt
then if I try the usual fastboot flash boot_a boot.img
I get preloader validation failed but my bootloader is unlocked with the OEM key that Motorola sent me. I get the warning bootloader is unlocked warning and everything.
version-sysimage-git_pi-dev-sdk_gphone_x86_64-userdebug=4833817
I think but I'm not sure about this this is unfamiliar territory Is there anyone with experience on this am I in the right direction at least?
