Hello guys, I wanted to share something I've discovered so that others will not repeat my same mistake. And yes I'm a noob
A little backstory
I have an Asian XT1033 Moto G, bootloader unlocked, rooted and using Faux's kernel. So, after reading some feedback about 5.1.1 for XT1033, I've been tempted to flash 5.1.1 over my 4.4.4.
The problem
I've downloaded the stock 5.0.2 Asia XT1033 firmware in img format, and proceeded to flash them via fastboot using Minimal ADB and Fastboot. (I tried to fastboot flash 5.0.2 stock firmware directly from 4.4.4 stock). Everything was fine, after flashing each part, Okay messages were shown. After rebooting, my Moto G booted and showed the usual "Warning Bootloader Unlocked" screen. EXCEPT, the "Warning Bootloader Unlocked" screen stayed for more than 10minutes......., I've spent the whole midnight trying to reflash back using 4.4.4 stock Asia firmwares (same stucked at warning screen), baffled, googling for similar problems encountered in hopes of a solution, but found nothing. The next day something came to my mind and I googled "the difference between fastboot and mfastboot" which led me to Mark_Venture's website, and after some reading, I first facepalmed myself hard and then screamed Eureka with my mind
What's causing this
To rephrase Mark_Venture, "fastboot is compatible with almost all Android devices, but is limited on how big the size of files it can actually flash, while Motorola have their own version called mfastboot which surpassed the file size limits of the usual fastboot", so basically when I tried to flash via fastboot, the command I've typed was "fastboot.exe flash partition gpt.bin" which is wrong and should be "mfastboot.exe flash partition gpt.bin", so basically I've used the usual fastboot.exe instead of Motorola's own mfastboot.exe. This probably explains why all the other files from the stock firmware are successfully flashed, EXCEPT the system.img_sparsechunk.0123 files due to their average sizes easily exceeding 256MB (my own take here, correct me if I'm wrong). This probably explains why rebooting after flashing via fastboot doesn't work because the system imgs are not flashed, and hence the phone get stucked at "Warning Bootloader Unlocked" screen because there is no ROM to boot to.
Alternatively, actually much more easier
You can also flash using fastboot a custom recovery, then boot into the custom recovery and either adb push or using USB OTG to install ROM zips. Personally I've used USB OTG with PhilZ Touch Recovery to install custom ROM and my phone finally boots.
TL;DR
Use mfastboot.exe instead of fastboot.exe when flashing via fastboot

Great find. TIL for me too
I used the WonderHowTo site incorrectly to flash a nexus 5 version of twrp unto my nexus 4.
My device at this point booted to a blank screen. It could still boot the boot loader at this point.
To "fix" this I found the correct version of twrp for my device and proceeded to flash that unto my device.
This has appeared to work since I can access twrp on my device but it is only thing I can access on the phone. When I attempt to boot to system through twrp I am sent back into twrp.
I have attempted to use the wugfresh root tool kit to unroot and return to stock using both soft bricked and phone is still working normally options with no success.
It can still boot to the boot loader currently.
I have logs from the toolkit if these can shed more light on my issue.
Is there anyway I can return my device to stock? Thanks for any response

attempted to flash stock and got the following error message
error: neither -p product specified nor ANDROID_PRODUCT_OUT set
Seems like you flashed TWRP to /boot. Easy fix is to download your ROM zip. Extract the boot.img and "fastboot flash boot boot.img". Then flash TWRP with "fastboot flash recovery twrp.img"
The locations and filenames of the files may vary. But hopefully you get the idea.

I flashed a boot image for mako_KTU84P and flashed recovery again with twrp but I'm still system booting into twrp.
My bootloader version is MAKOZ30f if that is any help
I probably flashed the incorrect boot image. Could you point me in the direction of reliable ROM zip's if that is the case.

Okay adb push a cyanogenmod zip from here and flash it in recovery. It should automatically install a working boot image. You should also flash the latest bootloader in the factory image with "fastboot flash bootloader bootloader.img" if you're using an outdated bootloader.
used the advice
I pushed the zip file using cmd and it appears to have been successful since I was given the summary of data transferred and how long it took once the process was finished.
I can't find the zip file in twrp to attempt to flash it.. Is there any reason the file name would change inside the device once it has been pushed?
Is there a way to flash the zip in question without pushing it unto the device?
Help! "Your device is corrupt. It can't be trusted and may not work properly." (Red)
Hello,
just recently i rooted my Nexus 6p device and unlocked the bootloader, i noticed however, after rooting the device i received an error on boot up stating "Your device software can't be checked for corruption. Please lock the bootloader." (Orange), but after researching on the internet many people said that was normal due to the boot loader being unlocked...
however my concern for today is i have flashed back to the factory images of marshmallow, and am now experiencing an error on boot up that Your device is corrupt. It can't be trusted and may not work properly." i followed the exact step-by-step guide on how to unroot and lock the boot loader on the link below however am still experiencing the issue, please help it will be ever so much appreciated.

I've had that as well with mine before. The way I fixed mine was a somewhat tedious process but it did work for me. Start by downloading one of the angler images from Google, then with 7zip, decompress the .tgz which gives you a .tar. Once more will get you a folder named xxxxxx-angler. (I think it was that way but not 100% sure since I'm not at my laptop at the moment). With your phone (unlocked) in bootloader/fastboot mode, run flash-all.bat. this gets you back to a fully stock system but still has the corruption flag tripped. Run stock recovery and do a factory reset and the corruption warning should be gone and back to the "normal" screen saying please lock the bootloader.

Try doing this process manually, if you're selling it. I would infer the data doesn't matter on the device.
Depending on which OS you are on. Focus your command prompt with fast boot installed to your directory containing the stock files (unzip the image zip)
Now do the following process manually. Step by step
fastboot flash bootloader bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash vendor vendor.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot format cache
fastboot flash cache cache.img
Now, if you still get the red warning. Repeat the process and add :
fastboot format userdata
DO NOT FLASH THE USERDATA IMAGE
If this does not work, I have other suggestions.
same prob in orange..plz help bro

To flash back to stock, you have to boot into bootloader and using fastboot to flash factory image.
But hey, you're in the Nexus 6P forum, try following this guide in the Nexus 5X forum:
https://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930
I just went through this. Just unlock your bootloader with the Nexus toolkit and it'll go away that's all i did

Hi guys,
I'm just finalising restoring an A2017 (China) to stock for warranty exchange.
I have gone back to stock OS, locked bootloader but I still have the TWRP recovery.
I believe all I need to do is flash a stock recovery.img though TWRP and voila I should be finished, but I can't find a download link that definitely points me to what I should use.
Could someone point me in the right direction?
Thanks!
EDIT - Actually wait a minute can I just install full A2017 factory OTA update through MiFavor stock OS which I believe contains recovery, does that mean that everything goes back to stock (including recovery)?
https://forum.xda-developers.com/axon-7/development/axon-7-chinese-stock-roms-t3436817
EDIT2 - When I try to install the A2017 B13 update.zip through MiFavor it says update failed. Should I install it through TWRP?
EDIT3 - Refused to update the whole image (update.zip) through MiFavor within the ZTE OS. I flashed the default recovery.img through fastboot, then I used the MiFavor recovery (not in OS) to manually flash the full image.
Anyway, got it to stock!
Where did you got the recovery.img?

In the link from my post above. Download the original stock ROM you want, unzip, one of the files is the recovery.img. FYI I had A2017 B11, installed B13 recovery.img and it worked fine.
I tried to flash recovery.img but it says: FAILED (remote: Partition flashing is not allowed)
What do I do? I'm on B13 stock with locked bootloader. I want to get rid of TWRP and back to stock recovery so I can get OTA updates again.

The first step in flashing anything is to unlock the bootloader, flash TWRP recovery, root, custom ROM etc. The inverse is the same. You are trying to flash an image to the recovery partition with a locked bootloader, which isn't going to work. I'd suspect you need to unlock your bootloader again, flash the stock recovery from the B13 stock image, and re-lock the bootloader. I am fairly new to the Axon 7 but I would consider yourself lucky if your bootloader is in fact locked. Typically locking the bootloader with anything but stock recovery is messy...

You usually end up with a DFU brick, sometimes only with fastboot. Very messy
There are flashable recovery zips for the A2017G, maybe @tron1 can make you one?
Hi there! I recently got my first android phone so wanted to install Lineage os 15.1 but messed it up right away as it's in now in boot loop! Here's what I did:
It was on Android 8.0 angler-opr5.170623.011-factory-0e60ceb6 but I unlocked its boot loader and installed custom recovery and I successfully flashed in the fastboot , vendor, radio and boot loader from Lineage OS 15.1 thread, now instead of following the rest of instructions, I madly decided to reboot the device using fastboot reboot and now I don't see anything except these colored circles which is what boot loop probably is! Please help me find a solution! Thank you!
edited: I have successfully entered into bootloader mode but don't know how to proceed!
I'd flash all the stock firmware in bootloader and start over. Grab the latest firmware package from Google's site, extract it, then run:
fastboot flash bootloader bootloader.img (name changes with version)
fastboot reboot-bootloader
fastboot flash radio radio.img (name changes with version)
fastboot reboot-bootloader
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash vendor vendor.img
Reboot to system
You'll probably have to flash your custom recovery again in bootloader after the first boot. It usually reverts back to stock.

Part 10 in the thread above^
I recommend you installing an easy official ROM.
With them all you need to do is a clean flash of the ROM
Since I'm still a noob so I need to muster up courage to proceed but I really appreciate your valuable input guys!! Cheers!! :good:
