Latest method? - AT&T LG G4

I just got an H810 it is currently on 6.0 h81021z....
I've been reading and apparently there is no way to at least root it... Am i correct on this? There is no way to downgrade or even unlock bootloader. No root method available? Should i just update and wait for my next phone?
I really miss my unlocked bootloader LG V10.... It died on me....

Well.... I guess its now worse... It auto updated to h81022b...

Does this really work? Anyone successful?

Those are my comments at the bottom in the Disqus discussion with the author of the post. I am running same version you are and I finally gave up. I cannot locate the TOT file for H81020n which is required for you and I that are now running H81022b. For us it would be a two TOT file flash process to get back to the version we need to root.
All of the links I have found for the H81020n firmware are dead or lead to something else. If anyone has a working link to the TOT file for H81020n it would be greatly appreciated.

ok ill explain the best i can for you.
Lets say for example that the bootloader was unlocked for the flex 2, if we downgraded with the current method that I did, then youll end up with a brick BECAUSE...after the 5.1.1 update, the bootloader was also updated, but if we had an unlocked bootloader, it would be no problem because then you can get right into fastboot since the bootloader is unlocked. however the reason my flex 2 bricked was because you cant downgrade bootloaders unless there is a specific way to do so, and if its unlocked...well since mine wasnt on the flex 2, when i flashed the TOT from ZV5 OVER a ZV6 bootloader, the rest of the partitions flashed, except for the bootloader end of it because it returned a "Version on phone is currently newer than the one being flashed" and declined the flash, since ZV5 wasnt build around the ZV6 bootloader, it doesnt know how or what to boot..
thats just a simple version, going into specifics is the Devs department, but in lamen terms, thats whats going on..if we had an unlocked bootloader it wouldnt be an issue because we could flash an older bootloader without the phone rejecting it. but once root is achieved on 5.1.1 then there will be a way to restore the FLex 2, the G3 you have although it may not have an unlocked bootloader, its been out for long enough to where exploits have been discovered, but if youre referring to upgrading and downgrading on Custom Roms, thats not the same thing, its only for official TOT's and KDZs or Official LG Firmware.
it would be like trying to flash a sprint variant with a tmobile rom....its just not built for it, its like having a Ford mustang with a V6 and trying to put a V8 motor in it without changing the computer/wire harness etc. it will fit...but it just wont work.
did that help for you to understand?

Ya i understand that part... Ive dealt with bricked phones... Ive recovered all but one.... Why are some able to downgrade though... In another thread soomeones says hes gone back aand forth a couplw times... Thats why i was confused..
So there's no way to root the Sprint lg g flex 2 (ls996) once it's on 5.1.1? Because we can't downgrade right? Wish I knew this before I bought one off Swappa.

Yeah I don't regret buying the g flex 2 considering I got it for $260 on Swappa. Really happy I got top of the line hardware for this price. I'm sure root will come or maybe a way to unlock bootloader so we can downgrade.

Tmobile pushed a 60mb update to my LG Stylo this morning? What to do?

Hello Folks
This morning I noticed, Tmobile pushed a 60mb update to my phone. I am rooted and unlocked but not on a custom rom.
Please advice what I need to do.
Thanks in advance

Is there any issuse with the update
I have not updated. As I mentioned I am rooted and unlocked. Not sure what to do hence posted my question in the forum.
I do not want to lock the bootloader. Just curious to see what others who might have got this update are doing about it.

1. You don't have to worry about lock bootloader
2. Which Software version are you running? v10e, v10i or v10j?
3. If you update there is a way to downgrade cuz we have previews KDZ's
I am running version 10i,
I am guessing tmobile wants to upgrade me to v10j. Is there a flash able version for 10j that I can use?
Thanks

Ok, you can go here and update to the latest version v10j using @GameTheory. V10j Full update/pre-rooted/untouch TWRP.

dummy you can't update that way you must remove all traces of root which the app can't do use the KDZ
If you are rooted and it says system update DO NOT INSTALL IT... it will brick your phone

Downgrade MM to LP?

I know there are a lot of threads. I read it's impossible. But another says possible using pda file with pit info, but i can't file proper file for g920i.
Are there any workaround to dowgrade?
I googled everything, but no luck. Stuck on MM.
Mm battery is bad for me.
Can we install custom rom LP while on MM bootloader using twrp? I know that only the bootloader part cannot be downgraded. Have someone created a hacked bootloader or somehow?
Or maybe prefer upgrade to nougat? I'm afraid because i will not be able to get back to MM after that.

There is only one way and that's with an engineering bootloader but this breaks fingerprint other than that it's not possible to downgrade to lollipop even with custom Rom this is down to being on newer marshmallow bootloader.

There is a guide in the general section I think, you might need to search for it. From what I saw last in it, some users got it working but others not so can't really comment on the success rate and plus it's nothing something I've done myself.

Nokia 3 8.0 Root - Is there a working method, or NOT?

Hello,
this is the very first time here at XDA Developers Forum that I do not find clear information about rooting a smartphone. I am talking about this Nokia 3 updated with OREO 8.0. Only a lot of confusion reading your posts, sirs. Nobody that is telling if rooting this model is possibile or not. So... can anyone says if it is possibile and how to do that, in a clear and simple manner?
Thanks and regards!

Hello,
thanks for your reply. I already read this thread.
So since I am on OREO, it seems I have firstly to downgrade to Nougat. Can someone please tell me how to do that, posting links to the official 7.0 rom, the software and a short guide? Somewhere I read you have to use OST, somewhere else SP Flash Tool...
Thanks in advance and regards

Hello again...
I am trying to downgrade my Nokia 3 8.0 to Nougat, in order to unlock the bootloader.
I have searched a lot for an official 7.0 rom... nothing official... I tryed to follow this guide:
https://forum.xda-developers.com/nokia-3/development/nokia-3-official-firmware-india-uae-t3674320
Managed to install and get a working copy of OST. Connected and start flashing the rom NE1-147I-ind-0-00WW-B02.nb0 (the one I thought it was the earlier one, since nobody wrote "7, 8, or another number" in the file name). OST got stuck at "Reflash service bootloader..."
Can anyone please write a clear guide on how to proceed to root a Nokia 3 OREO that was never ever unlocked before (i mean with bootload never unlocked)? I am going crazy, really...

which ost la version you have?
I finally managed to downgrade to Nougat 7.0.
Now, in order to get root, do I have to unlock bootloader first? Can I obtain the code only via a request to the_laser (that didn't answer me) or can I use an online tool ?

you need to unlock bootloader first, and you can PM code i will send you key, use only OTA through notification, don't use OST LA for this guide.

OK I figured out how to fix it.....I had to flash it in odin with G955USQS5CRH1_G955UOYN5CRH1_SPR firmware which i downloaded from sammobile.com. Than I followed this root method https://forum.xda-developers.com/ve...nt/root-using-odin-modified-firmware-t3693790 ...so try that and see if it works....but I do have one more question....i am trying to unlock my phone and dealing with sprint has been nothing but a headache. so does anyone know where else i could try to get this phone unlocked???? I'd really appreciate the help...
guys,
i have a question,
my friend has a s8+ model G955U. ATT version. unlocked.
baseband is = G955USQU1AQEF
he is on security patch May 1, 2017.
latest patch is september 1, 2018.
he is not receiving updates after that. at least 15 updates are issued after that.
from various online searches i have read that users are facing problems.
now i am asking if i can flash sammobile firmware ????
will he lose sim unlock or not ?
he will backup the data beforehand. MAIN query is about SIM UNLOCKING.
