Of course it will not boot. crDroid is rooted by default.
You probably tried to flash cf-auto root and that's ONLY for stock roms. Never ever use it for custom roms because every custom rom has standard root.
Because crDroid is based on CM you probably have to enable root in developer settings or flash the latest supersu trough TWRP.
You need to reflash your rom to get your rom booting again though.

Thank you!

No idea. You haven't told us how you tried to root.

Permanent Root?

After installing the lollipop update I lost the rooting to the phone.
I rooted my phone again but to be sure for the next time,is there a way to root Lenovo a6000 plus permanently?

When u flash new rom, you have to root again, no way for permanent exept root option include in the rom

You wanted to root again hah? Flash SuperSU.zip (based on my knowledge stock LL cannot/hard to root withe root.apk like kingroot. So, i think the latest tricks is flash the supersu.zip) but still... if you are Advanced User if not dont trying it

Dude sometimes root doesn't install properly i don't know why... I am on stock with 1.4Ghz oc kernel... Thing happens to me is that whenever i reboot my phone. Root stops working and says su binary needs to be updated.. I just have reinstall again and again to keep it working after boot.. So do u have any to solve it?

For me root still work even on reboot. To root my phone, i flashed SuperSU.zip with custom recovery twrp. How about you? Did you using same thing like me or by apps like KingRoot.apk?

Yup obviously.. By SU... I never use kingroot... Well i know it shouldn't have happened... Btw fresh rom install will solve it.. But i don't wanna do that.. Setting up phone again and again suks.. I just asked it because i thought if you might have had this problem! Thanks btw

To clear things up. Think of root as a system module (binary) ("su" module located in "xbin"). Each time you install a new OS, core partitions need to be formated (/cache, /data, and ofc /system). If the SuperUser module is not pre-installed in the new firmware you are flashing, it can be additionally obtained through Chainfire's installation zip. Nearly all custom ROMs have it and will work just fine, with some needing user input to activate it (Settings > Dev Settings > Root Access). While stock ROMs will NEVER have root capabilities pre-loaded.
So, all in all:
No, there is no such thing and will never be, as permanent root. Everything is being overwritten all the time.
Rooting and re-rooting the A6000 is safe and easy.

Restore LG US996 back to Stock

Hey does anyone know how to do this? I can't find any stock system or recovery images. I'm trying to make my device fully stock again (re-enabling encryption) so I can file a warranty claim. Would booting into fastboot and restoring using the LG Mobile Support Tool (http://www.lg.com/us/support/software-firmware-drivers) be all I need to restore back? Thanks!

The only way known so far to return to stock is to flash these IMG files in TWRP. As for re-enabling encryption that's something I have no idea of but these images system and boot should bring you back to stock. https://build.nethunter.com/misc/us996/v10d/?C=N&O=D by jcadduono

Did this work? I have a V20 US996 (unlocked, not US Cellular) that I'd like to return to stock, after something has corrupted somewhere, making it hard for me to flash kernels, su binaries, and the like. Isn't LGUP preferred at this point? Would flashing from TWRP bring it back to stock? I'd think that the custom recovery would still be intact when you're done. I can't seem to get LGUP to even start on my PC, let alone get it to recognize my phone.

Going back to complete stock I would suggest using LG's tools. After flashing back to stock you can re-lock the bootloader which should clear the boot-up warning.
If you want to try and just recover from bad flashing, and you have access to TWRP, you can try to flash the zip from here: https://forum.xda-developers.com/v20/how-to/us996unlocked-twrp-flashable-10f-t3544573
That should bring you back to 100% stock, minus recovery, and then automatically install SuperSU. I'll most likely be adding a zip without the automatic installation of SuperSU so that users can have a choice on what SU they want to use.

I'm actually trying to get MagiskSU working, so that I can be SafetyNet compliant for snapchat, androidpay, and concur (business expense app). I'd prefer to stay on the WETA rom for the extra tweaks. Lots of users post pics of MagiskSU working in WETA, but it seems they're all on other carriers with carrier-specific models. I'd think that the US996 would be EASIER to work with. Any suggestion? Thanks for the reply!

MagiskSU is actually the reason I want to upload the zip(s) without the automatic SuperSU. (Allow users to pick between SuperSU & MagiskSU). I started using Magisk so that I can bypass SafetyNet. Unfortunately I've only used the stock ROM so I don't have many tips for getting MagiskSU working on WETA. I assume it's pre-rooted with SuperSU so I would say performing a full un-root within the SuperSU app and then flashing the Magisk zip in recovery could get you up and running with Magisk. It's also worth nothing that I've only been successful with v11.6 of Magisk on the stock ROM. v12.0 causes an unstable system.

There is a v13 of Magisk that's out if you go to their git.
WETA has an AROMA installer, and you can choose to NOT install superSU. However, when I do that, the phone won't boot. It just sits there for 20min+ (flashing the rom with supersu takes about 5min to boot). The same non-booting issue used to happen when trying to update the binary, but I flashed something that fixed that. (I flashed so much stuff and something worked... I wish I knew which it was). However, SuperSU is like burned into my ramdisk or something, and it can't come out. When I tried to do the full unroot in SuperSU, it either fails, or the phone won't boot. But, there are options along that way that I don't know what to pick. Can you suggest what to do? Here... let me elaborate:
SuperSu v2.82 > "Full Unroot" > Continue (warning that some kernels auto-root. I'm on konverged... not sure if that's good or bad for this)
Attempt to Restore boot image? > YES
Attempt to restore stock recovery image? YES or NO?
.......YES "Uninstallation failed."
.......NO "Uninstallation failed."
Attempt to Restore boot image? > NO
Phone reboots within seconds... then sits and sits until I pull the battery.
....I then have to dirty-flash my ROM with superSU to get it to boot to the OS.
Helpful others with more knowledge than I have suggested that my problems are due to the latest version of TWRP corrupting ramdisk because of bad compression. Most of this is over my head when it comes to the actual development of recoveries, kernels, etc.

I doubt I'll try v13 unless there's a real reason for it (haven't looked at the changes yet). Since I'm stable on v11.6 I'm not too inclined to attempt to upgrade again (since v12 kept crashing the SystemUI).
Have you tried choosing not to install SuperSU in WETA and then flashing the Magisk zip right after completing the WETA install (before attempting to boot system)?
Another idea is to flash a stock boot image (since the one in WETA is modified slightly), flash WETA with kernel and SuperSU options turned off, and then flash Magisk.

no luck. Unless I have the wrong boot.img (I was given one earlier in trying to troubleshoot).
I flashed a boot.img that was supposedly for my phone, then flashed WETA with no kernel, no SU. Then I flashed Magisk. It flashed... but the phone wouldn't boot.
I restored the boot partition from my initial TWRP backup and tried flashing WETA again... followed by Magisk. This time, Magisk failed to run because it said SuperSU was already patched (I made the TWRP backup after installing SuperSU) and it couldn't flash.
I tried flashing WETA with the kernel, but no SU... and then immediately following it with flashing Magisk, and it wouldn't boot.
I should probably start a new thread, or post in the WETA thread. I got a little off-topic here. I initially just wanted to see if there was any advice on returning to stock on my US996.
Thanks for the suggestions

You're welcome! Sorry it didn't work. I do know it takes a few minutes for it to boot up the first time, but I imagine you waited pretty long. I have heard of phones taking 10-15 minutes to boot up after flashing.
I did add US99610h stock firmware to my thread at https://forum.xda-developers.com/v20/how-to/us996unlocked-twrp-flashable-10f-t3544573 if you want to return to the newest stock firmware of the US996.
I hope you are able to get Magisk installed as it's nice to get past SafetyNet. Good luck!

Root XT1644 on Nougat?

So I just updated to the latest xt1644 Nougat JP25.93.14-4 and am having an issue installing TWRP and getting it to stick. I installed it and even did a backup, but once I boot to System and then back to bootloader, and finally to recovery, it goes back to stock recovery. Also I am unsure of how to root this device now with Nougat. I've seen on a few sites differing methods. One site had a download for what they called a root package and it was a SuperSU 2.76 version. Another site said to use Phh SU and just install TWRP and then flash Phh. I don't want to mess anything up, can someone point me in the right direction since it seems everything in this forum is for a device other than the XT1644. Lastly, is it possible to revert back to Marshmellow using fastboot, or is that now not possible? I have unlocked my bootloader, obviously. Thanks.

After flashing TWRP you have to manually boot to TWRP without booting to system first. For rooting you have to flash ElementalX or Vegito Kernel and then flash SuperSU v2.79 SR3 or Magisk v12

I did manually boot it. I went back to bootloader, then choose recovery again and it goes back to TWRP. After I boot to system is when the issue occurs. If I go back to bootloader after booting to system, that is when I have the problem. Once I try to go into recovery again it goes to stack recovery. I am trying to install TWRP 3.0.2.0 Athene.

try latest twrp 3.1.0

I got it working. I had originally set it to read only and I think that was the issue. Reinstalled it and mounted system and then choose to allow modifications. It then worked. Now onto root, we will see how that goes.

When rooting do you still do the little systemless trick or is that already accounted for. Does the elemental X kernel play well and is it nice and stable? Thanks for the info.

If you're using SuperSU v2.79 SR3 beta ( https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133), this already is configured for systemless, and if you're going for SuperSU, that's the version I recommend. Any versions below 2.79 SR3 appear to have created boot issues on Nougat (or required the echo systemless command to work).
ElementalX (1.0.4 stock is what you want) is stable and is essential for rooting. Don't try to root your device without flashing a custom kernel like ElementalX or vegito, else if you try to root the stock Nougat kernel, you'll likely trip anti-root kit/anti-rooting security (dm-verity, I recall?) and will prevent your device from booting. By flashing ElementalX or vegito, you'll bypass that security.
A useful checklist to follow is in this guide here: https://forum.xda-developers.com/mo...de-root-moto-g4-plus-supersu-android-t3587918 Having a newer version of TWRP shouldn't matter (and in fact may present less issues). With step 6, you may choose to flash either magisk or SuperSU as mentioned by tywinlannister7 (I've not had experience with phh superuser, so cannot comment). If, at some point in the future, you wish to swap rooting methods, I'd suggest following the recommended unrooting procedure for your existing root manager (e.g. unrooting from the SuperSU app settings, or flashing the magisk uninstaller, check their respective pages on XDA) before changing root managers. I've used the aforementioned checklist to root a XT1642 on Nougat without issue.
As for downgrading your system to Marshmallow if you so choose, that is possible. Verify the MM firmware you need (a selection for XT1644, retus channel devices, is here https://mirrors.lolinet.com/firmware/moto/athene/official/RETUS/) and use that firmware with a guide like this: https://forum.xda-developers.com/moto-g4-plus/how-to/guide-downgrade-to-marshmallow-nougat-t3515961 If you're using fastboot rather than mfastboot, replace mfastboot in the provided script with fastboot.

NO! NO! NO! Do not use the systemless root method. That is for Marshmallow ONLY!. You will not be able to boot into the system after trying that and you may have to go all of the way back to flashing stock from fastboot to fix it.
ElementX-G4 kernel plays well with Nougat stock. I ran it with stock Nougat for a couple of weeks on my XT1625 without any major issues. So flash it from TWRP. Be sure you have the correct version. Then boot to system to check it out. Next reboot to TWRP and flash SuperSU 2.79. Boot back to the system. It will probably boot a couple of times before the system comes up. Don't panic. You should be good to go.

One other thing, can I back up the stock kernel? Or at least find it somewhere for download. Is this something I can backup using TWRP? Thanks again.

Got it figured out. Backing up my boot.img via TWRP ensures my stock kernel is safe. Already installed elemental X and SuperSU and all went perfectly smooth. Thanks again for the links.

Hey guys... I know I am late to the thread but if you see this, can you inform me how can I receive updates afterwards? I currently have twrp with elementx kernel and Magisk. And there is a security patch out for the phone. How can I install that?

Generally you'd have to revert back to a clean stock ROM, no TWRP, no ElementalX, no magisk. The stock ROM also needs to be in a read only state (no modifications allowed in TWRP) and cannot be debloated (OEM partition needs to be untouched).
You could revert back to a TWRP backup made before you flashed ElementalX, provided you did not let TWRP make modifications. You'd also have to find a stock recovery (if you flashed TWRP), and restore a stock logo.bin as well if you flashed a custom logo.bin to hide the bootloader warning. Then, you should be able to apply OTA/security updates. Attempts to apply OTA updates with TWRP on your device will likely fail and leave you in a soft bootloop unless you boot via the bootloader. You could try this to break the bootloop: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
The easiest and safest method I've found is to re-flash the stock ROM you have. Ensure this is the same firmware as you currently have and the latest firmware that you've flashed onto your device (don't downgrade your firmware if possible). You can re-flash without erasing your data by omitting the fastboot erase userdata command. However, I would recommend you back up your device anyway (e.g. in TWRP) and any important files, as although this procedure should not affect your data with that command omitted, any firmware flash has the possibility of affecting your device stability. That may require a factory reset/device wipe to fix. Backing up your data should be standard policy when it comes to flashing anything affecting your device's system/underlying firmware.
After re-flashing the stock ROM, you should be able to apply the OTA update.

Thanks a lot for the detailed answer. I really appreciate people like you. [emoji3]

root without custom recovery

Guys is that possible to root without flashing twrp recovery? Some says it's possible with magisk manager app which does not require custom recovery. I tried with kingroot but failed... Kindly help on this because I don't want to flash custom roms but I need root.

It's impossible as you can see kingroot was also failed. You need an unlocked device with a custom installed.

Guys is that possible to root without flashing twrp recovery? Some says it's possible with magisk manager app which does not require custom recovery. I tried with kingroot but failed... Kindly help on this because I don't want to flash custom roms but I need root.

1. its impossible to root without custom recovery
2. Magisk needs custom recovery
3. I have never had any luck in rooting any of my phones using king-root. it will not work on Xiaomi Rn3 or Rn4. not sure about other device
4. Custom ROM is different and Custom recovery is different, - To root you NEED custom recovery. Custom ROM can only be installed after rooting and its purely your choice.
Hope my answer helped. Feel free to get back if any doubts

You can temporarily boot into twrp and install root if you have unlocked bootloader

Indeed. With fastboot, you can boot into a local (ie, on your PC) copy of TWRP
Code:
fastboot boot mytwrp.img
