[Xt1621] Won't boot after trying to root

Hi guys,
I got a new Moto G 4th gen Xt1621 and tried to root it but after that it wouldn't boot anymore, I tried flashing back the firmware (which I found on a google search on a gammerson website) but now it won't boot, it shows the screen saying that the bootloader is unlocked so the warranty is void and the message that it will boot up in 5 seconds, and it gets there forever.
Is there any way I can get back the original firmware? Or a custom one, or really anything to make it usable?
Thanks a lot,
XNP

Hi guys,
I manage to fix my problem with the firmware XT1621_ATHENE-IUSMX_MPJ24.139-48_cid50_subsidy-IUSMXLA_regulatory-DEFAULT_CFC_v2.xml
And this procedure:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot
I got it from the stechguide page, but I can't post the link here unfortunately.
Thanks,

it is a exclusive xt1621 problem?

Can't re-lock bootloader!

So I tried CM13 and wanted to go back to everything official. So I restored the ROM from this place: https://github.com/motoxplay/stock
...using this guide: http://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750
Then I tried read the official Motorola guide to re-locking the bootloader: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images
Unfortunately it doesn't work. Using the guide, at the first step, I get this message:
Code:
fastboot flash partition gpt.bin
target reported max download size of 268435456 bytes
sending 'partition' (32 KB)...
OKAY [ 0.004s]
writing 'partition'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.141s
So I searched more on the web and ended up trying this:
Code:
fastboot oem lock
or
Code:
fastboot oem lock begin
and get this:
Code:
(bootloader) Please fully flash the signed build before locking phone!
OKAY [ 0.023s]
finished. total time: 0.023s
I also found someone around here who said that by flashing the ROM his bootloader was locked again. That didn't work for me. I'm still getting this
Code:
"Device is UNLOCKED. Status Code: 3"
on the bootloader.
What can I do?

My guess is you tried to flash wrong firmware, like Lollipop on the phone that already had Marshmallow. Or something that can't be flashed on locked bootloader, like retail firmware on carrier branded phone.

Well for the bootloader they only give us 5.1 and my ROM is 6.1. But when I tried to flash the 5.1 ROM from the same page I got the same message. I'm a bit stuck.
Then I tried to reinstall TWRP and again same message.
I'm stuck...

OK so I was able to install TWRP and then try to go back to 5.1 but that didn't work. It's a shame I thought I could trust that Motorola would give good information.

Oh! Now I got it!
So, just in case someone is confused like I was, here's how to do it. First, find the right ROM. Then, go into fastboot.
Code:
fastboot oem lock begin
You'll get the message that's in the title "Please fully flash the signed build before locking phone" (which should have been obvious I know but I thought it was an error message). Nevertheless, after that message appears you flash the ROM like you would. For me it was:
Code:
fastboot flash partition gpt.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash system system.img_sparsechunk.8
fastboot flash system system.img_sparsechunk.99
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
To finish the locking I did
Code:
fastboot oem lock
And that was it!!

Which ROM you used (5.1.1 or 6.0)?
Did you get it from GitHub or official site of Motorola?
Which country are you from?

That was in my OP : https://github.com/motoxplay/stock
You can't get it from an official source nor Motorola.
I used 6.0.1 the Canada Telus ROM. It also worked with the Bell version.

Thank you so much.
After hours of searching i couldn't find the right way to lock the bootloader.
Your post was like needle in the haystack for me.
Btw what's the status code of your bootloader?

You're welcome! I understand the frustration!
My status is 2. You can't get it back to what it was. 2 is an indicator that it was unlocked but that it's now locked.

Fail flash XT1575, firmware stock.

Hi, friends. Sorry, but my english is bad.
I tell you, I flash my firmware stock XT1575 6.0, but failed to be carried out correctly. Motorola have installed the drivers, as should be. I tried to flash with RSD Lite 6.2.4, and using commands in both made the same mistake at the same stage flashing. This is the error:
C:\Users\Lisandro\Desktop\platform-tools>fastboot flash modem NON-HLOS.bin
target reported max download size of 536870912 bytes
sending 'modem' (41686 KB)...
OKAY [ 1.041s]
writing 'modem'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 1.059s
Bootloader is unlocked.
I'm from Argentina, I tried a SIM Personal and working properly, test it with a SIM Claro AR and does not work, try registar network and tells me: "The selected network (Claro AR) is not available".
From already thank you very much.
I hope to resolve this soon.
Regards!

Modem flash fails frequently, repeat the command until it returns OK (may take 2 or 3 times) then continue. Make sure to follow all the steps in order, the order is important.

Depends on the firmware you are using.. according to Moto that isn't the right process, but using the latest MXPE firmware from here it appears correct. It is best to look in the firmware ZIP and find the flashfile.xml file and follow that, open it in a reasonable XML capable editor (not Notepad, but Notepad++ works well) and you can see the exact process step by step.
In looking at the file, pay attention to the steps with "operation" in them, those are the fastboot commands.

Thanks! Right now I'm downloading the firmware of the Motorola official page. I hope it works. Thanks again!

I downloaded the firmware from the official website, but I can not install it, how I go about flashing?

I do not know from where to start installing, to decompress the RAR I downloaded, unzip a file I can not open. Basically, once you downloaded the firmware from the Motorola, how do I install it?

It is a .gz file, you extract it like a ZIP/RAR file with a tool like 7-Zip.
The file from Moto is rather old, the one I linked above ( http://forum.xda-developers.com/showpost.php?p=67343754&postcount=171 ) is the current release.
You flash it like you stated earlier.

Yes, I unzipped the .gz file. I managed to get the folder with the files, but following the commands of the Motorola, I pulled the same mistake when creating the thread. You are downloading the most current version. Still I do not understand what the error:
(Bootloader) failed validation Preflash
FAILED (remote failure)
What is the cause of that?

Usually it means either the bootloader is still locked (which we know your's is unlocked) or the file is incorrect for your device. Sometimes it's a random error, try erasing the modemst1 and modemst2 first, then flash NON-HLOS.bin a time or two until it gives and OK and continue from there like normal.

I have not retested flash, but I solved my problem. The problem was that the phone was locked in Claro AR. No relation to the Bootloader error, but got what I wanted haha. Thanks for your time.
Greetings from Argentina.

You can only lock it if you have OEM image flshed into the system, which, by default requires all of the commands to be executed and will restore the OEM. You cannot lock it with custom ROM

Have you checked in this thread ? https://forum.xda-developers.com/mo...o-x-play-india-brazil-official-final-t3691100

Thanks, I checked and output is failed in general, but better than with other images (for both Indian and Brazilian):

fastboot flash partition gpt.bin OK
fastboot flash bootloader bootloader.img OK
fastboot flash logo logo.bin OK

Also looking for the official Bell 7.1.1 XT1563 image - can't seem to find it anywhere.
I've got a locked bootloader and non-booting device so I can't unlock the bootloader as I can't access the developer options to allow bootloader unlock.
All images I've tried fail to install as validation fails. Can't revert to an older firmware either with the bootloader locked.
Help?

have you found anything? i am i the exact situation.

Download the ROM from below link.
https://github.com/motoxplay/stock
Option 1:
Flash the given commands in link itself. (Try if this thing work).
Option 2:
Flash the given commands by skipping bootloader lines.
Option 3:
Take it to customer care. I am saying this thing because you can't find signature file anywhere.
Customer Center will hardly charge Rs.500 for software glitches.

Unfortunately, the Bell 7.1.1 image isn't available on the site.
All other images result in a validation failure.
