I did a very very very stupid thing...
Hey,
Hundreds of times I did this with no problem. But when your head is away bad thing can happen.
I flashed RETUS 5.1 stock ROM over my XT1527 Latin American carrier (possibly Movistar Argentina) . Flash failed. As it turns out I completely forgot to UNLOCK BOOTLOADER first. So I get the code and try to unlock, but the damn ALLOW OEM UNLOCK setting is turned off.
So here I am with a dead phone and no way to boot back. I can only go to (stock) recovery buth nothing I do there really makes any difference. So far I've downloaded two Latin American stock ROM images with no success (Preflash validation failed). However I am concerned that even if I find the right ROM, it will not boot either because of the downgraded boot.
Any options, ideas? Im stuck....Thanks in advance!
Different reason but same problem...
Dang that sucks mate.

If you can find someone with a working version of your phone, and in recovery push settings.db (I think) to the bricked phone and reboot into bootloader. then try OEM unlock
Or if you can find an official ROM for the device from Motorola, might be able to flash back to stock with the original firmware then try unlocking again.

I CAN get an identical phone to do whatever I wish with it. However the bricked phone has the stock recovery. Can I still push the file in that?
I have tried with several stock roms with no success. I can't seem to be able to get the correcto one. How do I figure out the correct CID and stuff? However my concern is that the correct stock firmware is XT1527_SURNIA_TEFLA-MSTCL_5.0.2_LXI22.50-53.8_cid12_subsidy-MOVSTLA_CFC and will not boot due to the bootloader being already updated to 5.1
same problem here with xt1528...
OK. I'm running the Moto Z unlocked 64GB version. Everything is stock. I unlocked the bootloader, and then flashed a custom logo to get rid of the "Unlocked bootloader" warning screen. Now the phone will not get past the new logo that I flashed. What can I do? I can get into fastboot or recovery, or boot twrp from fastboot(stock recovery still installed)
How can I get my phone to boot? Even if I have to live with the unlocked bootloader warning I'm cool with that. Please help!
Willing to pay $20 paypal or google wallet to anyone that can help me get my phone back working....

You should be fine, I'm assuming you flashed that boot logo without installing a custom kernel to disable force encryption and here's how I flashed stock when i did something similar.
This is exactly what I did from a bricked phone. I got a strange "error" message after flashing this that looks like the no command error, but after holding power it rebooted to Nougat.
Using Minimal adb and Fastboot:
fastboot flash partition gpt.bin
fastboot flash motoboot boot.img
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

I used the Mexican Nougat firmware from here, I'm on 32GB UK model though. https://firmware.center/firmware/Motorola/Moto Z/Stock/XT1650-03/
Just don't flash a MM one if you're coming from Nougat, that will not work. And remember to check the number of system chunks it may not be 16 for whichever firmware you use.
I'm currently downloading the stock MM firmware in hopes that it helps, gotta love living in the middle of nowhere with a 3mb DSL connection :-\
So basically I can't flash a logo unless I flash the kernal first?
Secondly, With this stock MM that i'm downloading, once I flash all of it using fastboot it should be back to stock completely except still have the "Bootloader unlocked" warning, yea?

Okay so you haven't ever been on Nougat? Just making sure because when you OTA to Nougat there's no way back.
I think so, to be honest I only changed the boot logo after I flashed LineageOS so I'm not sure.. but you need to disable forced encryption by flashing custom kernel to modify system files without it getting stuck booting up. I went through this myself when i first unlocked it, this is what fixed it for me. Good luck!
Yup it should be back to stock but still unlocked bootloader.

No I'm on Nougat now, But when I tried to flash one of the Nougat zip's from the post above it stated that I needed to have either 6.0* something OR 7.* something. Which made me think I could flash the 6.0 as an OTA, is that wrong?
I have the XT1650-03, which version of Nougat should I be pulling from that post? The one I got was obviously the wrong one :-\

Okay if you've updated to Nougat there's no way a MM firmware will work, thanks to Moto updating the bootloader making it incompatible. Where was the message that said you needed something? Did you unzip the file and flash each chunk in fastboot?
I think Rogers was a good option, i also have XT1650-03. Maybe try the Retmx like i did.

Well... I was able to download and flash the entire ROGERS version, My phone will boot to the Cyan M logo screen and then instead of the animation "ring ring hello moto" the screen just goes black. Eventually it connects to my computer but I can't find a way to turn the screen on or do anything. Downloading the RETLA version to see if that works since I'm pretty sure that was what was on the phone to begin with... *sigh*

Ah I don't know why that is, as i said I'm at sure what's best for your model sorry. The easy flash to Nougat guide link i sent you may be better, but yeah if you know it came with RETLA then give that one a try :good:
I think your best bet is to try that RETLA firmware.
I'm not sure how it does with Moto phones, but some variants are kinda picky with their software channels. Factory images designed for retail ("RETxx") devices might have a better chance since my RETAPAC model is on a RETMX build of Nougat. It's slightly older than the TELUS build that's newer and comes with some bug fixes, including one that resolves an issue where the 2 HP CPU cores "park" after some time of use, although I've heard of some issues when using that build with some devices. Mine's a bit iffy, but otherwise seems to run quite nicely.
Once flashed, if you wanna flash system mods, do not boot just yet. Flash or boot into TWRP and try the following kernel
https://forum.xda-developers.com/moto-z/development/kernel-turbo-z-custom-kernel-moto-z-t3493354
This disables forced-encryption and dm-verity (the latter is what's responsible for your phone refusing to boot). Additionally, you can flash SuperSU using the following method.

At this point i'm just trying to get my phone to boot lol. I wish I had read more to begin with... Knowing that unlocking the bootloader now breaks the safety net for Android Pay(it didn't with Moto X) is making me worry that it will also cause my Wells Fargo Mobile app to not work. At which point I might as well not even have the phone.
As of now I am able to flash the RETLA version but once I get past the Cyan M logo screen the screen goes blank and does not turn on even though my computer is recognizing that it's there. I'm about to try flashing the RSD rogers MM firmware(without the gpt and bootloader commands) and then sideloading Nougat to see if that gets me anywhere. If i can get it to boot normally I can at least sell it(at a loss) and buy another one. But I need it to at least boot up that way I don't have to sell it for 100 bucks lol. Any other ideas are welcome but I feel like i stepped in quicksand and the more I struggle with it the worse it's getting.

Well, if you want my advice, if you can find it, flash the firmware that your device was last at before you flashed Nougat.
An OTA bricked my Z, but flashing the full firmware made exactly for my variant brought it back to life. If you can find it for yours, you might get a lucky break.
Also, Magisk can help with SafetyNet, though it needs root access.

My issue with that is I can't figure out which firmware was made for my device. I thought it was the RETLA version but apparently I was wrong. Is there any way to figure out which one i need? I have all of the info from my getvar command in fastboot but it's not giving me any info(that i understand) that will point me in the direction of the correct firmware.
I'm currently downloading the rogers MM firmware to see if i can flash back to MM and then sideload nougat but I don't know if that's going to do any good considering that the screen won't load right now with the Nougat firmware I have on it.

Try RETUS if it fails?

You mean the RETUS 6.0 firmware? And basically go through the same thing as the ROGERS firmware (flash mm without GPT and bootloader) and then try to upgrade? I haven't been able to find a RETUS 7.0 firmware anywhere yet so I assume that's what you mean...

Yeah.
Because the only other fix I can think of is basically flashing the entire firmware including GPT and bootloader via RSD. But that requires firmware that's made exactly for that device and bootloader just to make sure everything is fine.
I'm still crossing my fingers in the hopes that your Z will make it through.

Well... to be honest the only reason I wasn't planning on rooting or using a custom ROM was because of the whole not working with android pay/wells fargo deal. If Magisk will help with that then that's definitely an option as well... Especially right now considering that I can't get ANYTHING to work if i can root, install a stock ROM and use magisk to hide the safetynet I'm totally fine with that as well. Any ideas?

Well, to even get Magisk and root to work, you need a working firmware.
The fact that your device showed the cyan Moto screen means that the firmware is recognized, and how your PC recognizes the phone means that something is indeed working.
But somehow, it's not displaying anything.
Sadly, the best piece of advice I can give right now is to try to flash a full firmware, especially one that was made for your device just to be safe. Motorola support probably won't be of much help since your warranty is void, though some did have success in the past, but I'd say that you might not get too much from them.
dm-verity is a pain, so I don't understand why it's not disabled when the bootloader is unlocked.

So right now my best course of action is to start with the MM firmware and work my way forward either way. Can I root/install stock 7.0 ROM/magisk from the MM firmware even if I'm keeping the 7.0 gpt and bootloader?

Well, here's the problem.
If you're on the 7.0 GPT and bootloader, you're out-of-luck. Because Moto has changed the rules on those to not accept Marshmallow-based firmware. Trying to flash a MM firmware will result in failure. Trying to downgrade the bootloader may cause your device to be F.U.B.A.R.
If you're still on the MM bootloader, just use the steps outlined earlier in the thread to flash N and then use the instructions and threads I linked to flash both the custom kernel and root access. If everything goes well, your Z should come back to life with those sweet-sweet notification shade goodness.
So I managed to downgrade to successfully unlock my bootloader however I am now stuck on 8.0.0.046(092Y) and am unable to OTA update. I have installed magisk and TWRP and they are both currently working however I am curious as to why I cannot update to a newer 8.0 OTA firmware. Any suggestions? The device is an ANE-LX3 single sim.
Because you used wrong firmware.
(092y) or similar numbers are here because wrong firmware..
At least that was case for me, when I installed single SIM firmware over dual SIM phone, and of course, that build number not exist in update servers, so no updates here, till you fix your firmware

HM.. in link you gave here, is writed about ane-lx1, you mentioned your phone are ane-lx3 single sim, so, I'm not sure it can fix your problem..
And I'm not used that files, and can't say anything about that.
And more important, what was full build number for your phone, aka ane-lx3c779, something like that, can you find it? Then I maybe be able to help.
And ,wulda be great if you type down all you did with phone, what used, etc.

I noticed the file name is LX1 however in the description it says its for all models which is confusing. Any idea where I could find an official firmware download for LX3? Even a functional custom rom compatible with my device would be fine if I could find one.
I used hisuite to first downgrade and then used the firmware from this post to dload downgrade again in order to unlock the bootloader. I then factory reset after successfully unlocking the bootloader which left me at build 046.
To be honest I cannot remember what the original build number was although c779 does sound very familiar.

Hello there brother. May I humbly ask how did you get your bootloader unlocked after downgrading? Can you share some steps please if you don't mind. Thank you
Hi! I don't know when phone rooting got this complicated.
The story is that I bought an A3 in India, and it came with my LTE bands locked, so I need to root in order to unlock them.
I unlocked the bootloader without any problems, but as soon as I patched the stock boot image and flashed it, my phone prompted me to factory reset it.
I imagine my phone isn't compatible with the stock image I got from the Magisk website, so I dumped my own following a tutorial here.
Now, I have TWRP in slot B (I can't seem to be able to remove it) and whenever I try to flash the original image, I don't get wifi.
I was able to patch the image with magisk and boot, but the wifi problem remains.
So now I'm stuck with 3G and no wifi.
Anybody can lend me a hand?
Thanks in advance!
UPDATE: I'm trying to go back to stock by flashing this: https://in.c.mi.com/in/miuidownload/detail?device=1900375
Just finished flashing, it has wifi.
How do I go back and try to get my LTE bands unlocked without messing everything up like I did today?

WiFi gets messed up when you flash an older image (i.e. From and older version such as 10.0.6), backup your own image in TWRP and flash that, or use the one that came with the stock firmware you just downloaded.
I have a brand new Galaxy A21 (SM-S215DL). In Developer Options, there is NO OEM Unlock toggle (not even a grayed out one; it simply does NOT exist anywhere in settings). I have tried several different variants of the date/time trick to try to get it to appear, and none of them worked. But while in Download Mode, KG Status is shown as `CHECKING`, so doesn't that mean it should at least be visible? Do I even need to unlock my bootloader? Is it even possible?
Using Frija, I managed to get what I believe to be the correct stock firmware for my device. I also grabbed both of the latest official and patched versions of Odin. Flashing the stock firmware works, but flashing the patched Magisk AP fails with an AUTH error for file `vbmeta.img`, which leads me to believe that I actually DO need to unlock my bootloader... but if that's the case, I'm having trouble figuring out how to do so without the OEM toggle.
Is there anything else can I try?

I also have the Samsung A21 from T Mobile (SM-A21UZKATMB). The phone is unlocked by T Mobile but there is no OEM bootloader unlock button under the Developer mode. Changing the date (forward and backward in time), then run the software update did not solve the OEM bootloader unlock button problem. I suspect the carrier (T Mobile) has disabled this function. You will need to unlock the bootloader to install the stock firmware.
To those who have enabled the OEM bootloader in the A21. Is your phone locked to a carrier in the USA like Verizon or T Mobile?
I also have the SM215DL, using straight talk utilizing verizon service, I also cannot unlock the bootloader. Everything you guys did, I did. Nothing worked.
samsung has done this to all A series phones intended for the U.S. from what i understand
Where there's a will, there's a way... someone has messed with my phone too do doesn't that mean that they're altering the data/data partition to r/w. Did you guys try fastboot flashing unlock vs. fastboot oem unlock. I'm going to contact Samsung about this and let u all know what's up.
And also why would there be a usb debugging port if this phone can't be modded? Idon't know the answer but maybe someone more expediency could come in and help us out. I also wonder if the flash_image command or just dd it would bypass it?

I confirm that I have rooted my A21S sucessfully using this modified magisk (U3 Rom). No need to patch the whole AP.tar file, just patch boot.img file only. I upload my patched boot.img for those who need it. Just flash it via odin in AP slot. Thank you very much @grccorps.

... exactly Step-by-Step, how u do it with downloadlinks of all Software, what u used !
Many Peoples writes, that they have rooted the A21s, but no one shows, how ! With the newest Firmware u cant rooted the Phone, because there is no working TWRP, SuperSU or MAGISK - Version out for this Phone !

Extract boot.img from AP.tar, then use modified-magisk to patched it
... this Methode is not working, i try it many Times, no RootAcess ! Again: if u have newer Firmware on this Phone (End 2020 - until now) u cant root this Phone ! Maybe on ure Phone an older Firmware ...
And this is my U5 patched boot.img

[SHARING] HOW TO ROOT A21S STOCK ROM WITH MAGISK
Hello friends I just want to share how to root A21S stock rom in case anybody needs it: 1. Unlock bootloader 2. (On PC) Extract boot.img.lz4 from AP...tar file, then copy it to phone 3. (On phone) Install ZArchiver to extract boot.img from...
forum.xda-developers.com
... and u shure, it its for the A21s or for A21 ?
The only hope of getting root on this phone is if you find a Dev who's interested enough to build a bootstrap recovery. I've not looked at the firmware & have no idea if there's an exploit that would work for that purpose.
Bootstrap recovery was the only way of getting root/custom recovery back in the days of Motorola D2 & Droid X, the original Droid X. Motorola was THE phone for development... Liberty ROM, Gummy ROM, Simply Stunning, etc.
I would not hold out hopes for that to happen here.
Peace - MS

No, Samsung has done this to ALL North American models ever since the Galaxy S8. The bootloaders are not user-unlockable, like they are on international models. However, some models can be rooted via a software exploit if they're running very old firmware, or some models can even be bootloader unlocked via special files, if their firmware version is old enough

I have a brand new Galaxy A21 (SM-S215DL). In Developer Options, there is NO OEM Unlock toggle (not even a grayed out one; it simply does NOT exist anywhere in settings). I have tried several different variants of the date/time trick to try to get it to appear, and none of them worked. But while in Download Mode, KG Status is shown as `CHECKING`, so doesn't that mean it should at least be visible? Do I even need to unlock my bootloader? Is it even possible?
Using Frija, I managed to get what I believe to be the correct stock firmware for my device. I also grabbed both of the latest official and patched versions of Odin. Flashing the stock firmware works, but flashing the patched Magisk AP fails with an AUTH error for file `vbmeta.img`, which leads me to believe that I actually DO need to unlock my bootloader... but if that's the case, I'm having trouble figuring out how to do so without the OEM toggle.
Is there anything else can I try?

and where does one get 'TWRP' for the Samsung Galaxy A21S?? Thanks for the post its very detailed with very clear instructions, and i agree with you this is the tried and tested and perfect way of rooting your phone, only problem is that this is an unperect world a world where 'TWRP' for the SM-A217F does not exist
I just received a refurbished SM-S215DL (A21,) not as my provider's solution to the VoLTE soon to be required for 4G devices thing and right now it's a pretty severe downgrade for me since it lacks a lot of basic functionality I'm used to from my 2017 phone running LineageOS. Obviously it's pretty unlikely or probably outright impossible to ever see a real LineageOS ROM for this thing (and even if someone ever does it probably would be insanely unstable or incomplete,) but if I could at least root it (even if I have to manually patch or something) it would really help me out a lot. Has just nothing really been found short of sending some unknown person online some very very key device details and money (which I don't have or I'd be buying something else anyway)? (Also kind of suspicious that whatever method they're using isn't something available to the public anyway...)
