[Q] Revert to Factory Image

Hi all, I just wanted to ask this before I start flashing custom ROMs:
If I want to restore the factory image, would I be able to just flash the zip from the google dev website for the Nexus 10 (https://developers.google.com/android/nexus/images#mantaray) In recovery?
I noticed that in the contents of the file it has a new recovery image and all so I would imagine that I can't do this but thought I would ask. If no, what is the best way to get back to stock? I know there are some guides with several fastboot commands to erase everything you've got and then build it back up from scratch, but is there no other way?
Thanks in advance!

Personally, I used the [Nexus 10 Toolkit]. It really can't get much easier than that.
It provides everything you'll need to download and flash the stock image/recovery, re-lock bootloader, etc. Not to mention all the other fun stuff you can do with it.

TWRP and failure to take OTA

Hi,
First let me say i really don't mind flashing stock recovery to my 1575 to take OTA's (may secupd, nougat?, Etc..) but i am wondering is this necessarily required? Are moto's ota's hard coded to only work with stock recovery?
I copied the may security flash ota and attempted to install it in twrp manually, no go. I'm assuming the only option is to temporarily put stock recovery back on?
Thanks for the input all... Much appreciated.

Flashing a recovery takes around 5 seconds and no hassle. I don't even wonder if this or if that. But it's your choice anyway.

Not just Moto, all devices I've come across require stock recovery to take an official OTA.

i flash twrp instead of boot

hi all,
i made a mistake when i wanted to flash magisk, instead of boot twrp i flashed it. I want to keep the stock recovery to do OTA update.
I found the full firmware of the moto g4, inside i found the stock recovery but i doubt if it's the latest recovery.
Anyone can tell me which is the latest version?
thank you

Rooting Query - Is Elemental X really needed?

Hi All,
I just recovered from a hard brick on my G4 plus due to various complications from flashing the Elemental X ROM as suggested before flashing the root file.
Though the root was successful on the stock Nougat OS (NPJ25..93-14), the main issue which I immediately noticed after rooting was that there was no notification sound. I fiddled through all the settings to get this working, but didn't get through. Not sure if anybody has faced this issue.
So, my queries are as below:
----- Why is a custom kernel needed to root? Just flashing a root zip file wouldn't be enough?
----- What's the issue with the sound getting disabled after flashing the Elemental X kernel? Is there a fix to re-enable the notification sounds?
----- Is there any other custom kernel which I could flash when rooting on the Stock N OS if indeed a custom kernel is required to root? (this shouldn't screw up the notification sound)
Regards,
Shonilchi

The stock kernel from Motorola can only have temporary root access. Check the thread by Shreps if you're interested in that. There's no other way, at the moment to get permanent root access. Why? That's some way Motorola has worked out the kernel.

Hadn't happened for me when I rooted my device. Specific to you, for some reason. Try flashing again. Backup your existing kernel (Google how to) and restore the backup if anything goes wrong.

You can, of course try Dreamstar's Vegito or rahulsnair's Quark kernel's stock versions and then flash a superuser ZIP file (the same phhSU or Chainfire's SuperSU.
You should not have had a hard brick. Perhaps you had a soft brick. A hard brick would require a blank flash using special software to fix. What did you mean when you said your phone got hard bricked?

Great thanks for the answers. Yes, it was probably a soft brick which happened. I was able to downgrade to MM and then do a N upgrade.
BTW, I see many supersu.zip files floating around to be flashed. Do you recommend a most suitable one to flash for the G4+. I know that I need to install the pHH supersu app after I boot up.
And for the stock kernel revert I found this statement: "Do a nandroid backup and do advanced restore instead of complete restore. boot.img is the kernel." - can you please confirm if this is a good way to revert back to the stock kernel?

Install the phhSU zip as mentioned in the link in the post above, or, install the latest SuperSU Beta from the SuperSU XDA thread.

All you need to do is backup boot.IMG from TWRP and restore it upon a botched flash.

Was walking around here and couldn't help the itchy need to leave my own straight answers to your questions, mostly as an exercise, since G4/Plus is no longer that news nor the thing of excitement it still was (arguably) back in March 2017.
Whatever, as for superuser means, @topjohnwu "Magisk" has gained a lot of popularity over former Chainfire's "SuperSu" since he's no longer supporting it and development seems pretty much at iddle nowadays. Say I'm a purist (which I'm not), that's why I'm still relying on latest, all @Chainfire built SuperSu (v2.82 SR5) probably for the last time though...
On the other hand, ABSOLUTELY YES, it's a good way and you can restore just boot.img right from your nandroid backup to revert back to stock kernel. Actually, we all know it's the best practice to always do a nandroid backup right before messing around with our devices and TWRP comes with the benefit to choose which partitions you can either backup or restore...
As for @flar2 ElementalX, it wasn't really a must because I refused upgrade to "N" due to the lack of Xposed support (both came a bit late) but I flashed it anyways in order to "fix" the so called "burn screen" issue primarily... and just because it's cool. No unwanted side effects by the way and my personal experience with Moto G4 Plus aside from the "burn screen" issue (which turned out no big deal for me) is of pure joy until early days of 2018 and counting. There you (all) have it.

u need to reboot the device once or wait for sometime..the tones comes back automatically..its not a kernel issue. Since, no one else is facing it...
Custom kernels are better than stock as they give u an option to tweak for performance or battery.. if you don't need it keep it stock.. if u want it, the method u know is correct. Always make backups, incase u mess up.
Good luck!

Moto G4 XT1644 Restore Stock

Help! I'm trying to restore the stock version of my US Moto G4 XT1644 after flashing ElementalX, Magisk, and phh's SuperUser. While I'm pretty sure I unrooted successfully, I don't know how to go back to the regular kernel, or if that's even necessary, or how to to relock my bootloader. I have tried most of the guides here, but flashing the boot img always fails and I can't relock my bootloader. If someone can point me to a reliable boot img or help me understand what I'm doing wrong that would be greatly appreciated! Sorry for being a noob
