***EDIT***
Solved. Not sure what I did right, but installing SuperSU 2.82 via TWRP and wiping the cache twice seems to have done the trick. No pulling card or battery - ran through one bootloop and then settled down after a minute.
So I'm trying to set up a backup phone after successfully rooting my primary phone using 5.1.1 (BPA1) and having some problems. First phone went OK and is stable. This one is giving me fits.
Downgraded from 6.0.1 to 5.1.1 using Odin.
Used Kingroot and ADB to get root.
Installed TWRP 3.0.2.
Made backup before I did anything else.
Download mode shows DEVELOPER
The problem starts when I try to install SuperSU. If I install it from TWRP the phone goes in to bootloop on restart. I've pulled the SD card, re-partitioned it, reformatted it, etc.
Tried different versions of SuperSU (2.71, 2.74, 2.78) and all result in bootloop. Tried the SuperSU directly from TWRP - same thing.
RootChecker reports not rooted.
I can restore the backup with TWRP and that stops the bootloop, so I don't have a bricked phone or anything.
Any ideas how to install SuperSU and eliminate the bootloop? Or am I at some point in the process which requires something else?
Even though I was successful on the primary phone, that still doesn't mean I really understand what I was doing.
Thanks,
Spumco

Just bought the phone and Dev Unlocked it and Rooted it, after abit of failure I managed to root it. Phone worked fine I tried to install a mod and that's when I thought If there's any errors I can just delete everything and install but that wasn't the case it would stay frozen, I tried aroma manager it wasn't showing much files so I thought I would try and install the stock rom again that didn't work I then tried another rom and just been booting to CWM the sd won't mount so I been sideloading these files. :crying:
I wanted to share my somewhat scary experience and how I resolved it.
It started when one day I wanted to flash an updated rom using TWRP so I rebooted into recovery and TWRP all of a sudden asked for a password.
To resolve the issue I had to ODIN an older version of TWRP, fix permissions and then reinstall 2.6.30.
This got me back into TWRP and I thought all was resolved.
I then proceeded proceeded to wipe everything and even format to ensure the device was clean. I flashed the rom w/o issue and it booted up fine. After I got it all running nicely I rebooted into TWRP to make a backup. The backup was successful.
I then rebooted to system (after backup completed) and the my phone froze on the loading screen. I pulled the battery and restarted the phone and it booted into recovery mode.
I thought maybe there was a permissions issue to I did a fix permissions and rebooted to system via TWRP. Phone still froze when booting. I pulled the battery again and again it powered up into recovery mode again. I decided to wipe everything again and install an older backup that was proven to be good (which I restored previously w/o issue). It restored and rebooted fine. Then I turned off the phone and turned it back on and the damn phone booted into recovery again @#[email protected]# Rebooting to system in TWRP causes the phone to freeze, Cold booting the device boots it into recovery. So I was essentially stuck once I installed anything if I ever had to reboot the phone.
The only solution that worked was to take the stock image (included stock recovery) and root.zip and flash that to the phone. After flashing it I had to go into the stock recovery as the phone still didn't boot properly. I didn't pay much attention but the stock recovery brought up a number of errors but I was able to chose an option (sorry I don't recall what) to fix them.
After it was fixed the phone booted up w/o issue and also rebooted w/o issue. All appeared to be back to normal.
So I went and flashed TWRP again through ODIN and restored my backup and all is back to normal.
As an FYI .. I grabbed the stock image from here :

So i was trying to flash hacker kernel
It bootlooped.
So i reflashed renegade and tried reflashing.
it rebooted
now everytime i try and flash anything it reboots
super su is missing.
I installed super su from play store
when i go to flash binaries it reboots.
I updated TWRP
still same thing.
If i flash anything it just boots back to recovery.
Any thoughts?
Flashed back to stock and rerooted.
Did the trick.
Would you consider editing the topic to add the word "solved" please? The might help give others direction.
So when you started out from stock, you used Odin to install TWRP, but then thought you could get rooted by installing SuperSu from the Play store, which did not work.
Proper steps are to install TWRP using Odin with SuperSU on your phone. After TWRP is installed, instead or rebooting completely, reboot to Recovery and flash SuperSU that way.
Is that about right, @phelony?

No I had previously been rooted fine and dandy. for some reason TWRP started just rebooting on any flash.
so is it not going into bootloop mode anymore? because i've been having this problem for the last 6 months. i thought i'd try again and still doing the same, it'll get to the setup at the beginning and then reboot back to twrp????
Hi guys it's been a while since I've rooted any devices but decided to root my LG G PAD 8.3 (V500), since it is so outdated. I'm gonna go over exactly what I did on how I got here to better understand. Sorry in advance for the long winded post.
-Anyway, I had to downgrade to 4.2.2 by using the LG Flash Tool 2014.
-Then, I rooted my device by running root.bat Also, I had SuperSU when I rooted.
-After rooting, I installed TWRP via the play store, downloaded the most recent twrp.img and flashed it via the app. It took me forever to get to recovery by pressing power+volume down and then pressing power+volume down+volume up. But after what felt like 20+ tries, I got to TWRP recovery.
-I wiped my phone and flashed the most recent Lineage ROM. Unfortunately, after flashing the ROM, I could not flash GApps because it rebooted to the ROM after flashing. TWRP let me know that I had to update TWRP and since I did not have the play store and I was once again having trouble getting into recovery, I downloaded the most recent TWRP apk.
-When trying to open the apk, it gave me a "can't open file" message which I didn't understand why. After rebooting, for some reason, it then let me run the TWRP apk and installed the TWRP app. This is when I found out that I was no longer rooted because TWRP notified me. I double checked with root checker and indeed I was no longer rooted. I have no idea when or how that happened.
-Again, I couldn't get into TWRP recovery until I plugged in my phone to my PC and for whatever reason, it helped me get into recovery. I wiped the phone and proceeded to flash Lineage and GApps.
-I read that by flashing SuperSu I may regain root, so downloaded an updated SuperSu, went into recovery and flashed SuperSu. When rebooting, the LG screen came up with a message at the top left corner reading "secure booting error! Boot certification verify". At that point, I was in a bootloop and had to go into recovery, wipe and flash again minus supersu. So I am now on Lineage with GApps and no root.
How do I regain root? And anyone know how I was able to lose it? Back in the day when I was into flashing, I never had these problems and never lost root out of nowhere like this.
Also, if I wanted to get back to stock LG 4.2.2, how would I go about that? I know that currently, I can't use the LG Flash Tool 2014 because my current ROM does not have a USB Software option in order for the tool to recognize the tablet.
Any help would be greatly appreciated, thank you.
I have been trying to root my J6 SM-J600FN for a while, and I thought I was getting close to rooting it when I installed TWRP. But then, my phone was stuck in a boot-loop. I was able to fix it by installing current firmware, and I decided to attempt it a second time. I got the same result. Is there anything I can use to install TWRP that doesn't result in a boot-loop? I just want my phone rooted and be done with it.
As far as i know, trying to root stock rom isn't easy. I could be wrong but idk. You can try by:
1. Flashing stock
2. Flashing TWRP
3. Format data
4. Flash DM-Verity and Disable Force-Encrypt then flash magisk.
And i think you can't flash kernels on stock. I could be wrong but idk.
Hey, how did you even install TWRP?
Before I tried installing it my model number was "SM-J600 FN/DS" and now after the install, when I plug it into my pc it says that it's "FN-600G." Whenever I try to boot it in system mode it's stuck in a loop.
I haven't tried flashing the newest firmware yet because I can't even download it for my country.
Sorry, I am a total newbie and can't seem to fix it.

Hi Guys,
Did you manage to do this? I was experiencing the same bootloop issue and I think it is the version of Twrp (I was using 3.3.1-0).
I used Odin to flash a lower version 3.2.3 found here after which I flashed this DM Verity + Magisk.
Root Success!
