Help with un-rooting LG optimus f6 d505 - General Questions and Answers

[edit]Solved[edit]Hello i seem to have a more or less unique problem, or possibly one that has allready been answered so many times i can not seem to find it on google?
so the problem.
I have a optimus f6 (the d505 version) wich i have sort of succesfully rooted about 3 years ago, problem is i seem to remember soft bricking it and then reflashing it with something called lg flash tool? and needing to unlock the bootloader in order to un-brick it. After wich i used Kingo for rooting and everything worked like a charm ever since.
here is where the problem starts, right now i want to sell it, and i have a client to sell it to, problem is the guy needs his banking app to work. And after un-rooting it with the same app, and then doing a factory reset, the banking app still recognises the phone as rooted, and to make matters worse even the OTA update fails because of the same reason. Now i think the problem is with the bootloader being unlocked, i can think of no other reason why the apps think it is still rooted, i can re-root and re-unroot with kingo at any time and every function of the phone and the root acces seems to work. When un-rooted every root detection app i have tried from google play tells me the phone is not rooted, exept the fore-mentioned OTA and banking app.
My plan is to re-flash the allready updated basic rom, wich i got as a kdz file from a site called lg-roms.com( it does appear to have the correct phone version and carrier, i did a imei verification) and then use fastboot to re-lock the bootloader.
My question is since I am sort of a noob with theese sorts of things, will this solve my problem, aka will it remove all traces of root, i would like to know since i risk bricking it anyway i want to know if i can get any sort of results
[edit] So ya i really doubt anyone will have this specific problem, however if you do, i managed to solve it by flashing stock and locking the bootloader with fastboot, problem seems to have been originating from there

[Q] Back says H-L02, software and PC says H-L01 - Help to root!

I wish to root my phone, the software says its L-01 and when i plug into PC it also says L01, but after following the root process i have no SuperSu access etc, despite it all saying it was successful during process.
The back of the phone actually says its L-02, and this is a refurbished phone so i suspect someone has fiddled with it before me.
Can anyone give advice how i can continue to root the phone, do i have to flash L02 back onto it? is that safe or is there a risk i may now brick the phone?
Many thanks
Nobody have any advice whether it should be flashed back to L02 , or just trying to flash with L01 as it appears to be on now?
I dont want to brick the phone, but do wish to root as need to clear a lot of bloatware and also have issues with Google Play store i think may be solved with root access.

how can i see if my phone is fully Unrooted

Hi all . I have rooted my phone (LG G3) and because of a problem i was forced to go to my service provider (LG) since its still under warranty . So knowing that rooting voids warranty i unrooted using superSU and then i verified with root checker getting back the message "sorry root access is not properly installed on this device" . So i thought that its all done and proceeded to use my warranty . couple of days pass and they called me and said that root was found on my phone and cant take it under warranty and i have to pay if i want it fixed which i am not gonna do cause its 200 euro to fix the motherboard. I asked them if i can do anything and they said that if i remove completely the root i can go to them again and they manage to fix it for free. So i flashed a new stock ROM to be sure this time is fine. Now what i am asking is can i somehow check in depth if its rooted or ever been rooted like traces and stuff . is there any program that lets me do so? i tried to find the program the technicians used but couldn't find anything.
Thanks in advance for all the answers and for your time .

I killed my beloved Galaxy S3

Well, this is my story. I tried to revive my old Verizon SIII because I really like that model. The problem is I never noticed the 4.4 bootloader lock. I rooted my device after a factory reset, I tried to install the cyanogenmod but at the start the custon recovery wont trigger despite installing the adequate app, first I believed KNOX was the issue so I proceeded to unistall it with TitanimBackup, that made the "custom" Samsung boot screen appear but then a "Unauthorized sofware blah blah blah" message from Verizon appeared so I used download mode to reboot sucessfully, then I remembered that the bootloader wasnt unlocked so I proceeded to unlocked with EZunlocker and the unlock was successful, when the TWRP manager app asked me to reboot to install the custom recovery it never did, just bricked. My questions are, my phone was already running a form of custom rom for region-free SIM card operation, as far I know the device was NOT on 4.4 since it wasn't even on the US anymore and Verizon update services don't operate here, as I remember my sytem version was 4.0.4 why did it bricked? if I buy another device what I must check to avoid another bricking? Is there any way to recover my device? it is a hard brick, noob here.

S7 edge current situation.

Hi there I've been away from rooting for a bit and i have been trying to root a broken s7 edge more recently. Its got 6.0.1 stock on it. It all works except the volume up button. I seem to be able to access the phones files and sd card in windows. I can also flash 6.0.1 it seems by forcing it into download mode. But its still stuck on FRP and i can't find any way to unlock the bootloader to install custom software. I've been trying all the tutorials i can find but none work. Is this Samsung patching these security holes and so they no longer work? The password Is unknown for the Google account and it's not blacklisted or anything like that I've not used the SIM in any tutorial though. So is this doable or is it impossible at present? It all seems a lot more secure since my last root :s Thanks

Try this for bypassing Factory Reset Protection(FRP)

As for rooting the device, there aren't many methods that work on lollipop and newer firmwares other than maybe trying Kingroot and Kingoroot or flashing TWRP(not an option for you since you have a locked bootloader) for your model number then flashing Super or Magisk.

Rooting a Xperia 6616

There aren't many new topics on this model so here we go,
My z3 stock came with 5.0.1 and as far as i know never (the 6616) had the 4.4 as an option. SO downgrading didn't work, so i'm stuck trying to root this with 5.0.1 and after two days of browsing this site there really doesn't seem to be a way to do so. Eventually i said $%#* it and rooted it using kingroot but after rooting it, root checker passed the root but would not give proper access when installing root apps such as busybox and the ta backup tool.
So i didn't realize that the keys ive been trying to save are useless anyways if i update android and the main reason for me going through this is i really don't like 5.0.1. Only thing i haven't really looked into doing is seeing if kingroot will let me unlock the bootloader then trying to flash an update. SO has anyone successfully updated a 6616 z3 (to 6) who didn't start off with 4.4?
