I am unable to lock my bootloader for XT1643. I ended up getting here because I did the following:
> Purchased a Moto G4 plus (XT1643)
> Manually updated to official Nougat(Soak Test).
> Unlocked the bootloader.
> Flashed twrp recovery
> Flashed supersu2.78.zip
> Because it gave me a bootloop so I flashed 6.0.1 firmware(24.139-13) for XT1641. This took away my network and wifi connectivity
> Installed modem from original firmware (24.139-64) for XT1643. Got back radios on my device.
Now when I try to flash the complete 24.139-64 firmware, I get an error when flashing boot.img and recovery.img saying that it is not signed/verified and that downgrading is not possible(or something on those lines). So I have flashed the system.img from the firmware and have baseband of 24.139-64 now.
I believe I need to downgrade from the 7.0 boot.img and also be able to lock my bootloader before I can root my device, or install the soak test again, or both. Please guide me how do I go about doing this. This XT1643 is my primary phone.
Edit: I found the -63 baseband file, flashed it, boot.img and recovery.img flashing still failed but I have got -63 baseband now.
bro did u find any solution? please share me. Thanks

Can I ask how you're flashing your MM firmware? You might have to use adb and fastboot to get a reliable transfer.
I'd also try flashing this ROM using these steps (for XT1643) as I've had good luck with it, even though I'm on an XT1642
https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1643-updated-signed-t3460695
The steps appear similar to downgrading your phone from Nougat to MM: https://forum.xda-developers.com/moto-g4-plus/how-to/guide-downgrade-to-marshmallow-nougat-t3515961
Hello
I need bootloader.img and boot.img from android 7.0 Because before few months I soft-brick my X force. I can go to Bootloader. But I can't unlock my bootloader or flash with RSD android 6.0.1
I need the two img to try flash it with fastboot.
I've been trying to flash the modem from the stock rom used in South America on a XT1622 but everytime I flash another rom (XT1625 or the XT1621) the baseband never updates to ATHENE_EMEA_LATAM but it shows ATHENE_EMEA_DSDS_CUST.
The commands I used were:
fastboot flash modem NON_HLOS.bin
fastboot erase modemts1
fastboot erase modemts2
Does anyone knows how to do this?
Hi i have found the method for go back to naugat from official oreo. Many people got navabr bug in oreo and also battery drain faster in oreo.
I have tried lots of method to go back to naugat but what happen always i got imei null...
so using this method you can go back to naugat without loosing your IMEI...
So what you have to do is first download naugat firmware from below link:
Naugat Firmware With December Patch
and the steps for fastboot:
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot flash dsp adspso.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0 (repeat up to 12)
fastboot flash oem oem.img
fastboot erase cache
fastboot erase userdata
fastboot erase DDR
fastboot reboot
enjoy hit thanks
Can you verify the link please? The MEGA link sends me to a 'file no longer available' page.
Also, I'm hoping you're linking to the Feb 2018 Nougat 7.1.1 firmware, not the Dec 2017 firmware - if you really want to downgrade. Be aware that your bootloader is still likely the Oreo bootloader (not the Nougat bootloader - there's no commands to flash the bootloader, but then again, your Oreo bootloader may block a downgrade anyway), so attempting to take Nougat OTA updates may hard brick your device. A hard brick may occur if you use OTA updates after downgrading to Nougat from an Oreo firmware newer than the April 2018 security patch. Be careful.
My moto g4 plus, model XT1643 was hardbricked, i installed blank flash on it, it has rebooted into bootloader mode of blankflash with no android logo, and has locked oem of my phone. I cannot install a stock rom now as the oem is locked and when unlocking oem from cmd prompt its asking me to enable oem from from developer options, which i cannot do as my mobile is not booting. Please help as to how can i install stock rom into it as my bootloader and oem is locked now. Any help would be appreciated, thanks.
tried to pass the last stock if I am not mistaken version that is or updated passes without being with bootloader unlocked.

Following a blankflash, you can only boot into the bootloader, which is normal. It seems that using a blankflash sets your bootloader to be locked, regardless of if it was previously unlocked in the first place. Provided you can flash a stock ROM, your bootloader should become unlocked again.
Have you tried flashing the April 2018 fastboot stock ROM from https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 ? The guide there should be useful in how to reflash stock firmware to your device, and as it's the newest firmware that has been leaked, should rescue your device.
If you want to keep your bootloader unlocked and try to save your data, then try the following flashing commands instead of the ones in the guide. Be aware that you may have to factory reset your device should it boot but be unstable.
Code:
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 reboot
These commands should flash the April 2018 GPT, bootloader, system and modem to your device. Please try to avoid hardbricks in the future by only flashing stock firmware as new or newer than your bootloader, and please do not use old OTA updates.

Thank you so much, I've restored the stock rom following your guidelines, my phone is working fine but im not able to install any OTA updates after that. Should i just skip any OTA updates from now on, please advice. Thank you.

If you flashed the April 2018 security patch stock firmware, there are currently no OTA updates, the April 2018 security patch is the latest available.
If you fully flashed the latest firmware as I mentioned, you should be okay to use OTA updates. Just in future please remember to not use OTA updates if you downgraded your device by flashing old stock firmware.

Without a blankflash new enough to flash to the device, I don't think so. You'd have to consider a JTAG repair, a motherboard replacement or buy a new device.
