[Completed] LG G90 startup problem/TWRP - XDA Assist

Hi xda,
i currently have an lg g 90 (pretty old model) that is rooted with either kingroot or super su, im not sure. I originally had kingroot but used super su me to try to switch to super su. It said it was completed but kingroot was still there. I then restarted my device and it got stuck on the load up screen with the t-mobile logo. I've tried restarting it many times. Could this possibly be a brick? If so, how would i fix it? Nevermind, i factory reset my phone but not in the setup, it wont let me go past wifi. I'll click next and it will take me to a blank page and back to the wifi setup. Also once this problem is resolved, would it be able to install twerp and cm13 on it? Thank You!

[Completed] LG Volt 2

I just bought my LG Volt 2 a month ago, and I'm ready to make it MINE! Unfortunately, I think this phone is too new, because I can't find anything helpful on how to root it. I tried "kingroot" and after it did a few things, it said I was successfully rooted. BUT, when I started up "SuperSU" it says it has to download some things, and its never successful and informs me to restart my phone and to press the restart tab. When I press the restart tab, it says "attempting to restart phone" but it can't. I'm on the 5.1.1 operating system, and using an LG Volt 2 (LGLS751). Is there any advise out there that someone can offer me? Am I REALLY rooted? Has anyone successfully rooted this phone yet? If so please tell me where I can find the steps. I have faith that my XDA community will pull through. Thanks everyone!

[Completed] Asus FonePad KO12

I have a problem with my device after I attempted rooting it. I think it's FonePad 7 FE170CG. I attempted to root it with Framaroot, Z4mod, Towelroot, One-click root, but I think I got it with Root Zenphone. But I think I did it wrong, 'cause my device is still not rooted, and now the 'factory reset' button is gone, and I can't put a lock on my device. Even when I try to, it is still on 'none' and not 'slide', 'PIN', those stuff. I tried the hard reset too: wiped the data and did the recovery thing, but the Android robot goes dead and it says "Error". I am thinking of flash recovery but I don't have a PC, and my device isn't rooted, apparently. Is there a way I could do that thing with just my tablet? Or another way of undoing all the changes I've made in my device? Please help.
Sorry.
Also, I'm sorry if I'm posting this on the wrong uh... board or something. It's my first time to write on a forum, so I apologize if I have violated any rules. Also, thanks and have a good one.

[Help] Idol 3 Rooting

Hi,
a couple months ago, I successfully rooted my Idol 3 with the "root.bat" method. I realised a week ago that my phone was not rooted anymore and I tried to re-root it in the same fasion, but it didn't work. I then proceeded to unlock the TWRP recovery loader and re-installed SuperSU from there. I used RootCheck to see if my device was rooted and it is not. I can't gain root access either and SuperSU prompts me with a dialog box saying "SuperSU binary needs to be updated". If anyone can offer any help, I would greatly appreciate it I'm a little nooby when it comes to rooting, so if I was too vague in my description of the problem, please point it out so I can be more specific.
Thanks,
-Yasio
Found a solution if anyone is ever intrested!
Turns out my firmware had some sort of issue, so I used the Mobile Upgrade Q utility and just re-flashed the phone with the stock firmware. You can find a whole tutorial here: http://forum.xda-developers.com/idol-3/help/return-to-stock-firmware-recovery-t3216077)?
It's super easy. Then, I just re-rooted the phone with the TWRP method DallasCZ came up with also posted here: http://forum.xda-developers.com/idol-3/general/guide-unlock-bootloader-root-alcatel-t3161878
And there you go, I got root access back and got rid of the freakin' "Binary files need to be updated" or w/e prompt in SuperSU.
Thanks again to DallasCZ and others for their hard work on the rooting scene for the Idol 3. I love this phone and you made me love it even more

Can't find root method for LG Phoenix 2 (LG k371).

Hey all!
I recently bought the LG Phoenix 2 (LG k371) from ATT, and I really want to root it. But alas, I was unable to find any root method that works for my phone. Does anyone know of a method that will currently work for my device? It is running MarshMallow 6.0. I can update with any other info needed.
Thanks!
Lg Phoenix 2 root

Tried KingRoot, no dice
BUMP: I really need a method for this...
I have the same phone. Kingroot did work for me. You have to run it several times but it does eventually work. Also had the random reboot issue on occasion but I did get the bloatware off. What I would like to know is once its temp rooted, is there a method to get permanent root? Any custom recoveries that work for this?
Well I totally boned my phone I think. Kingroot works but it caused a lot of instability. It reboots the phone within minutes of getting temp rooted. So I tried supersume to remove kingroot (which seems to also have a pretty bad reputation as far as privacy goes) to replace kingroot with supersu. Everything seemed to go fine, the binary updated and looked good. Once the phone reboots though, it freezes on the AT&T logo. When I try to factory reset the android pops on screen for about 5 seconds and nothing changes. I can't do anything with adb. Whenever I try to list devices the phone is detected but it says it isn't "Authorized". If anyone has any ideas I would really appreciate it.

Installing super su when rooted with king will brick Everytime you can temp root to uninstall the at&t bloat but that's about as far as I got phone keeps rebooting every few minutes when rooted I think I'll just get a new phone
I'm really not a fan of the fact that this device de-roots itself on every reboot, I know the developers have more popular models to address, so I'm not complaining. I was just wondering if anyone knows a way to keep that from happening and safely get rid of KingRoot and put SuperSU on instead...
Supersume
Sent from my SM-N910T using XDA-Developers mobile app
root
did you try this guide?
http://forum.xda-developers.com/showthread.php?t=2684210
Stay away from Kingroot and supersume, you are going to brick your phone!!! You'll have to send it in to LG, and your phone will never be the same again!!!
It only takes one attempt of kingroot, and no more security updates from at&t, Error: !!your device is suspected of rooting!!
(even if you uninstall kingroot & unroot)
Phoenix 2 root
Anyone have any advice on hacking into the system somehow to bypass the boot loader in order to fix the bridging problem at&t left us with? Or possibly something like flashily to flash directly to device or so we can disable bootloader security, or bypass at&t security or something like the old school ways hacking the system if possible. I don't understand HW,SW,KERNEL,LINUX,CODE,APPS so its hard for me to hack it myself. Although, I have successfully rooted, flashed supersu and twrp'd my htc one m9. I have been into buildprops and enabled hotspot tethering and disabled data throttle through proxy servers and HSM. I just don't know where or how to start the root procession this device Cuz I'm still a newb. Please no one click root suggestions, I prefer the knowledge not the instant gratification! Thanks in advance!

I tried this method but it froze on the last step, I sat there for an hour while my phone was trying to run the script but nothing would happen.
Tried it as well

Yeah I tried that before I attempted to Kingroot and then Supersume. Did the same thing. If anyone knows of a way to de-brick the phone when supersume fails I'd appreciate any help. Not sure it's even possible.
LG k371 is one of the k8 series.
All K8 were compressed at lz4 not the gzip. SuperSU v2.66 (and other previous system-less version of supersu installer) can't decompress LZ4-compressed kernel. So that procedure won't finish the last step.
There might be two ways to solve this issue, either repacking into gzip, or waiting for supersu's support to lz4.
I guess the supersu's support to lz4 could be easier. But I don't think ppl are working on it.
At that thread, someone succeed rooting another K8 model (LG K8 k350n), with a different chipset, Mediatek MT6735 . I guess you could check it out.

Did you try booting the phone into fast boot settings?
