I tried rooting the device when It was on Nougat.
but it went wrong and caused boot loop.
I tried flashing the rom MPJ24.139-13.1.
it says prevalidatin failed.
writing 'recovery'... bootloader) Image recovery failed validation
(bootloader) Preflash validation failed
since its a downgrade from android 7 to android 6

You need twrp and su.zip to Root.
Did you lock bootloader while downgrading ?
I did unlock my bootloader couple of times.
Did you get unique code on mail id ?
One mkre thing is check if oem unlock option is ON or not
You can find it in developer settings.
I installed twrp and also SuperSU..
Then phone got bricked after the boot up.. so I falshed marshmallow rom again and tried rooting.. when I enter the key vch I get from Motorola, tat tym only it's showing invalid boot state..

Quick question, did any of you on XT-1640 manage to safely root your phone?
You know, without losing wi-fi, data etc.? Which method did you use.

I did, got no problems so far. But you will lose all data when unlocking the bootloader, if its already unlocked then rooting isn't going to wipe your data. I also installed xposed and got no problems with it

Moto g4 Plus stuck at bootloader
Hi,
My Moto G4 plus is now stuck at bootloader. Below are the details of errors that I get
Recovery Mode - Failed to validate recovery image
Start the phone - Failed to validate boot image
Flash stock ROM via ADB - Pre flash validation failed
Flash stock boot.img - Image boot failed validation (Security version Downgare)
I am not even able to unlock the bootloader as the adb returns a message saying I need to toggle 'Allow OEM Unlock" in the Developers Menu. I connot do that as I cannot boot my phone.
Please help.

Looks like your trying to downgrade firmware there and from what I'm aware you can't downgrade certain sections like bootloader etc. What is it you're trying to achieve?

I was just trying to flash the stock rom. Had some glitches in my phone. While I was trying to flash via adb, couple of steps failed and then I was not able to boot my phone back.
Im sure that I'm using the latest version of ROM. However, it's the one before the latest security patch. However, the boot image and recovery image should remain the same.
Here's the version that I'm trying to flash.
XT1641-XT1643_6.0.1_MPJ24.139-13.1_cid50_subsidy-DEFAULT_CFC
No matter what I do now, I just cannot get my phone to boot in recovery mode or just boot normally.

What exactly have you tried already?
Have you tried "fastboot flash recovery ***.img" ?
Of course, only the Nougat recovery will work.

Hmm command not allowed usually says that bootloader is locked. You did unlock it manually again right? Because it often is locked even though it says unlocked on the bootloader.

Untick signature verification. Custom roms are not signed any more. That's not a problem in fact.

That error is normal since TWRP isn't signed. As long as you see [OKAY] at the end of flashing, reboot to recovery after you've flashed - you'll find TWRP there. Then you may reboot as normal.

In addition, when you've flashed TWRP, reboot straight to recovery. If you reboot to system, the stock recovery will overwrite TWRP. Booting to recovery will fix TWRP and make TWRP overwrite the stock recovery. As I mentioned above, after this, you can reboot as normal.

Hey guys,

plz give me a hint or throw a link in at me, If i´m missing something obvious :silly:
Can't you just install the official LG suite software on a desktop or laptop and then use that? It will probably detect the missing or "damaged" recovery and then automatically "repair".

Now I'm on stock rom with stock recovery, but the "fastboot oem lock" leads to a "corrupt device" that will not boot anymore. Can't the H870 (europe) be relocked, once it was unlocked via unlock.bin?
Isn't that the exact same procedure but then simply choosing "lock"?

i thought it was, but as a mentioned, it leads to a startscreen, that says: your device is corrupt and will not boot. after flashing the unlock bin it boots again

Is there a "lock.bin" file that can be fetched from the LG site maybe?
From the LG developer site:
4. Once unlocked, it cannot be undone.
There is no turning back once you have unlocked the bootloader. You will not be able to revert your phone to locked status.

In TWRP > Mount > untick and re-tick /data and then try formatting it.
Yip tried tht too... So the phone started back but it's reverted back to its original state... Locked bootloader, unrooted etc...
I can provide full service firmware VNS-L23C605B370 / VNS-L23C605B364 / VNS-L23C605B121
Ok... But can I use any of those tht you've outlined safely, becuz my phone works fine so far but it appears the data partition is damaged. Also the twrp recovery im using is 3.0.1 so I gonna try updating it.
Right... so I've managed to get my phone back up and running by flashing the recovery2, recovery, cust and system files with L23C605B120 instead of B102 as it was. i've also managed to install twrp and rooted it. I've noticed that not any version of twrp works. Only the 3.0.0 version. Now i need help with updating my firmware from B120 to B362 if possible. through the official updater i attempted to install an official update but it kept failing... any suggestions... anyone?

Hello
as I see you can use twrp 3.0.
then, from then b120 MM.
1 bootloader code.
2 installs twrp.
3 go to wipe. check all except SD card.
4 go to install, install update.zip b362 and install update datafull.zip b362.
5 restarts.
here is.
2017.02.25 VNS-L23C605B362 update.zip http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1258/g104/v77299/f1/full/update.zip
update datafull http://update.hicloud.com:8180/TDS/...-L23_hw_la/update_data_full_VNS-L23_hw_la.zip
now, for vns-l23c605, there is a firmware b374.
you can install it too.
to do it.
you had to download all the files (full-ota-mf-pv b362+full-ota-mf b374) to your computer and handle them with winzip.
