Boot loop after attempting to 'flash a factory image | Return to Stock'

Firstly I hope that this is an OK place to post this if not could you please guide me to the correct location, also I pretty nooby at this.
My phone before hand;
XT1562
I had successfully managed to install cyanogenmod from this forum thread using TWRP.
The Bootloader is unlocked.
What Have I done;
I wanted to return to stock and so I followed this guide.
I am now stuck in a boot loop at the after the bootloader, in my inexperience I feel it might be that there isn't actually a ROM installed due to this message appearing often "(bootloader) has-slotartition: not found" or "(bootloader) has-slot:system: not found" as visible in the CMD log below.
This is the CMD LOG from my attempt, feel free to ask for info and I am very greatful for any and all help.

Don't flash gpt and bootloader.
And check no of sparsechunk files and flash all of them.

As I have already tried those two flashes, should I remove them if so how, or do I juts flash the rest and forget I had previously tried gpt and bootloader?
Thanks for reading

Just skip those two and flash the rest

same problem
Me too experincing the same commands in cmd . How did you installed the os ?. thanks in advance .

i had bootloop also.i think the commands regard other firmware version maybe lollipop.in the point it says sparsechunk 1 to 6...add sparsechunk 7,8 and 9 with copy paste...i resolved this way...

I have the same issue on Moto g5s plus (sanders). The stock os wont flash and just bootloops, and I have tried flashing different versions of the android sanders os.

Use the link below. Below link will definitely work. I personally did multiple times. Worked flawlessly.
https://github.com/motoxplay/stock.
Make sure that you will flash only 7.1.1 else your bootloader gets corrupt.

Guys i recently wanted to unroot my phone Moto X Play(XT1562) LUX so did it from the supersu app only and then wanted to lock the bootloader but the fastboot devices were not showing on my laptop and so i installed lineage os on my phone and since then it is rebooting into the recovery mode and in order to start the os i need to press start from the bootloader.
I saw that dd command helps fix this pls guide me.

Moto G4 XT1622 Bricked......

Hi There,
I hope someone can advise and possibly provide help resolving this problem.
The Moto G4 is not able to boot to OS, It only boots into bootloader, cannot go into recovery and cannot go into Factory Mode etc.
The error i get on the phone is....
"Start Up Failed"
Failed to verify hab image boot
Failed to verify boot image
ERROR: Failed to pass validation, backup to fastboot
Fastboot Reason: Fall-through from normal boot mode
I have tried to clear fb_mode and tried to unlock the bootloader without success.
I have tried various stock roms to get this fixed. The phone has never been unlocked and not been rooted.

what have you done to your phone at the first place when it was working? did you unlock bootloader? were you flashing some customised roms? have your try to root? ... or something else?

Hi,
Nothing like rooting flashing roms etc. I think an update installed and booted to the Start Up Failed error.
Thanks,

this seems like the boot loader is locked some how. any ideas for this?

Device didn't start successfully. Bootloader issue?

So my moto G5 plus has had a problem. I was on stock oreo and it just crashed one day prompting "Your device didn't start up successfully". So I repaired it using the Lenovo software repair assistant and it worked quite perfectly. Now that I had a reset I thought of trying Pixel Experience [AOSP & CAF] ROM and flashed it.
It crashed again and now Lenovo software repair assistant is not able to repair it. Any particular reason? I had USB debugging on and OEM set to unlock when this ROM was working fine. I downloaded the stock ROM repair assistant suggested and tried fastboot way but it also didn't work. There was always remote failure.
Also, adb isn't detecting my device. fastboot is detecting though. here are some details:

My device is connected to pc as "fastboot potter S"
I also trying getting the unlock key through fastboot. While I got the key, I was not able to unlock it (remote failure). Is there a solution? Any other details required from my side?
Fair warning: I'm so not a pro at this (clearly). I already ordered a new phone but the feel that I'm not able to get a solution from hours and hours of browsing xda is just disheartening. I refuse to give up on this one. Too many good memories associated with it

Well if you were on pixel experience then your bootloader is already unlocked so no need to do that. The fb log shows security version downgrade which happens when you try to flash an older firmware. Try the getvar command and it should show some more details and then just download the correct firmware. Does your twrp work?

Exactly. Grab the latest firmware 8.1.0_OPS28.85-17-6-2 (February security patch) and flash it. There's no newer stock firmware so a downgrade isn't possible

I can't get pass the boot screen. It just says device didn't start successfully. I'll try the getvar and will post again. I can't even reboot the phone or the bootlocker using fastboot.

Unlocked bootloader Phone stuck in bootloop

I successfully unlocked my bootloader last night. I went through the process of patching the img file through magisk to root and flashed it via fastbooot. I have been stuck in a loop since. I can still get into fastboot. I have tried Smart Assistant and RSD but they wont detect my phone.
I tried a using different firmware as others have posted and i'm still stuck.
here is my process on powershell:

You need to wipe everything with fastboot commands. Then flash stock again. Also there's no need to do any of that anymore to get root. Just flash the latest magisk in TWRP next time.

Thank you for the reply
Should "Fastboot erase" wipe it all out?
do you know where I can the correct stock room for XT1962-1?

Extract all files from stock zip and run flashall.bat file at command prompt with phone connected in bootloader mode. This will flash and erase all to correct retail stock at Lolinet mirror
https://mirrors.lolinet.com/firmware/moto/river/official/RETAIL/

Flashall.bat file
Extract into adb folder (same as all files in stock zip file)

Install TWRP and then flash Magisk 20.2 and Magisk Manager APK

While patching the boot.img for your first installation, did you choose "Preserve force encryption" in "Advanced Settings"?
