Need Help rooting US996 with Magisk 22 - LG V20 Questions & Answers

This is my first attempt to root and despite reading allot still very confused on allot of the lingo and what to do. I had unlocked the bootloader with TWRP.
I tried rooting with Magisk 21.4 and it sent me into a boot loop and I did not realize a backup in Switch was not the same as in TWRP so had to learn how to put stock firmware back with LGUP.
I have US996 running Adroid 8.0 Kernel 3.18.71 software, OPR1.170623.032 build.US99620F Never rooted. Bootloader unlocked TWRP
Next day Magisk 22 came out
The app is on the phone, I am looking at the instructions and confused how to root.
1. is "patching", rooting?
2. I just want the root on stock Android 8.0.0
I need the boot .img of what? Of the stock android 8? Of something else?
3. I tried getting a boot image from LG Extract but only saw a DZ file and if I tried to extract that only see something with the word " boot_6 Bin" So I am still missing something on how this is done.
Is the boot.img usually of the software you want to try running or always the stock? Do you have to root eac time you try different or once rooted always rooted to flash other roms?
Thanks for any guidence. I tried on my own for days and really lost on all this.

Hi,
What is the best way to ask for help on this? Thanks

I still am requesting help. I need to root my US996 so I can get at least PIE running as I have an issue with an app that says it requires 9 or above.
If somebody can point me in the correct direction I'd appreciate it.

On Alpha Omega Rom, I had the best results with the included Magisk installer. It's now on version 22 without any issue. Keep in mind that version 20.2 might have some compatibility issues with the V20. That won't have any impact on your ability to run software that requires Android 9, however.

This is how new I am with this stuff. What is an alpha omega rom? Does that mean stock factory rom of Android 8?
I have version 22 on my phone. Do I need to root? How do I root? I do not understand how this works now. I have tried reading help files but I dont understand what to do after I unlocked the bootloader.
What do I need next with Magisk 22 to root the phone or do I just need a rom of Android 9 or higher?
Thanks for any guidence.

Alpha Omega Rom is a custom build of the V20 system software based on LG's original stock Rom (see the links thread for more information). For the North American variants of the V20, several releases of the stock Rom based on Android 7 and Android 8 were released. Only the Korean model received a stock Rom based on Android 9, and it was never backported, so, if it's Android 9 (or newer) that you're after, you'll have to go for one that's not based on the stock rom (which will cause you to lose certain exclusive features, including the stock camera app, FM radio, Voice-over-LTE, and probably other things).
Once Magisk Manager is installed, it can act as a root manager, but only if your device's bootloader is already unlocked, which can only be done on certain variants (US996 North American unlocked is the easiest, but it is possible on some of the others as well, but only if you roll back to an exploitable version of the stock rom and use the Dirty Santa strategy described on this forum). Installing an unofficial Rom or kernel also requires an unlocked bootloader.

Thanks I have the bootloader unlocked using TWRP and on stock oreo 8.0

Which first?

Its been a few years so i was needing a refreshing (& though simple question, i cant seem to find exact answer).
I have the sm-t337a tab 4. If i plan on rooting it but i also was looking at installing a ROM, which order do i need to (or which do you recommend) do them in???
Thank you for your assistance

You always have to root first before you are able to install a custom rom. That said, to the best of my knowledge, there aren't any custom roms available for the SM-T337A. Unfortunately, AT&T and Verizon lock the bootloader on their devices now. This means that you can't have a custom kernel or a custom recovery. Since Cyanogenmod and similar roms based off of it require a custom kernel, you can't have any cyanogen-type roms. That said, a stock based rom (anything capable of running on the stock kernel) should work fine, but as I've said, to the best of my knowledge nobody has made any roms like that for this device yet. Sorry to be the bearer of bad news.

That sucks. Guess I'll have to be satisfied with just rooting it and maybe a different stock rom, if any available.
I was just searching on here & I'm not sure what instructions are the ones I need for this tab. I saw where someone says they tried towelroot & 1 other but did not work, & other similar posts, then find several posts mentioning that they have rooted it, so I'm not sure what way DOES work to root it. (I also found on another site, which I don't know if Im allowed to post the external link, "Working Tutorial How To Update/Upgrade Samsung SM-T337A To Android 5.1 Lollipop!) Needless to say Im a little unsure of what method I need to root it. ANDROID VERSION: 4.4.2 BUILD: kot49h.t337aucu1ank2
Also Is there a alternative stock based rom (with tutorial) you might recommend ?

All you can do is try towelroot. If it comes back as failed, then oh well, it doesn't mess anything up. Towelroot will only work for kernel dates before July 2014 I believe. There are NO custom ROMs, no recovery, no alternatives for this tablet. No developer interest, no carrier support, so no android version beyond 4.4.2. We have been abandoned by AT&T with no way of getting any updates ever again because they locked us out. So we are stuck with a worthless pile of crap tablet that gets more laggy by the day. No more carrier variants of any device for me ever again. International only.
rootng that works

kingroot works perfectly on the T337A tab4

Nexus/pixel 6.x.x style rom, for rooted bootunlocked VZW_BPB1_ODEX_DEODEX_V9 SM-G900V

Sry about the terrible shorthand. Finally broke down and factory reset my verizon gs5. Before setting up i decided to roll it back, root it, and get a debloated PB1 rom from here:
https://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370
So, if like me, and you have the nov/dec VZW OTA update on your phone PJ2 if i recall, this link got me rolled back and rooted. This method added busybox which i didn't really understand, safestrap which i actually kinda liked, and initially kingroot then the flash went to superSU.
I kinda liked the marshmallow os a touch better with the google now launcher and everything verizon as removed as possible vs 5.x.x. Basically the verizon OTA update to marshmallow essentially bricked my phone (not enough space after like 3 years of never re-formatting). I love my tablet that essentially runs just a bare bones no BS google android marshmallow software similar to what a pixel has or nexus had.
Doin more reading looking for such a rom i found this link:
https://forum.xda-developers.com/ve...t/rd-unlocking-galaxys-s5-bootloader-t3337909
This successfully unlocked the bootloader. They omit that you should make sure you have the rom on he phone or sd card before starting. So before using odin make sure the rom is on the phone and matched the bootloader unlocker you wish to use. This method of flashing used TWRP recovery which i found to be...different than safestrap but functional all the same.
QUESTION 1
Is there a rom for the SM-G900V that is similar or identical to a non branded google device like how the pixel comes stock?
I haven't messed around with the phone since unlocking the bootloader and flashing it to the VZW_BPB1_ODEX_DEODEX_V9 using the TWRP Recovery. Basically if my best bet is a debloated stock but rooted vzw rom that is 6.x.x and then manually removing/deactivating the garbage from vzw apps i'll do it. But figured this was the place to ask if there was already a rom out there that works on the SM-G900V. Because i can easily put a rom that does the job instead of tinkering more than i have too.
QUESTION 2
Now that i used the SafeStrap_PB1_Bootloader_Unlock_AIO.zip and flashed VZW_BPB1_ODEX_DEODEX_V9.zip using the method from the second link. It APPEARS i can just load a 6.x.x rom and use TWRP Recovery to flash that. Am i mistaken? Will i need to do the unlock bootloader process over for the PD1 PF4 or whatever boatloader unlocker corresponds with the rom. OR...now that the bootloader is no longer verizon'ed can i basically swap roms to my hearts content as long as they do not also try to install a new bootlaoder??
I have no idea how to "tag" either poster from the links i mentioned but i'm certain many here as well as they could answer both questions easily.

Is there a Nougat (CM 14.x) version that will run on a rooted Verizon Galaxy S5...

Is there a version of CM 14.x that will run via Safestrap on a rooted S5 (CID 11)? I have not been able to pull the different pieces together to answer this for myself. I know CID 11 cannot have the bootloader unlocked. I know that there is such a thing as Safestrap though I have not used it. I know about using ODIN to return to an earlier version of Android in order to be able to root. I know that CM had (has) a version of Nougat. I just don't now whether that can all be tied together to allow me to run a ROM based on CM 14.
Can someone please answer what should be a rather simple question? Or point me to the appropriate thread(s)? Thank you.

Yo, I see you are a man of culture as well. My S5 is currently running LineageOS 15.1 (Official!) and it is BEAUTIFUL. Runs like a dream. If you want, I can show you how to get the bootloader unlocked and flash TWRP. Send me a PM if you're interested! Best of luck on your journey bro.

Jiwan, would you mind sharing the procedures here or a link to them? I have the SM-903VL model, and while I understand it's a different device, it may not be so dissimilar. I have been attempting root and twrp flash for a while and it seems 2 things are at issue, 1. I had no clue what I was doing when I started, and now, while I have some knowledge, I realize just how much I am going to have to learn If I want to figure out a root method.
2. This SM-903VL is locked up tighter than a nuns corset.
Your knowledge on the afore mentioned procedure would help me understand the workings of these phones a bit better, and, on an off chance, might actually do the trick of at least getting twrp installed.
I have the stock recovery file to insert into the TWRP.

If I could revive and piggyback on this discussion - I'd like the help you offered with getting my g900v re-rooted with TWRP running. I had a nandroid backup and accidently deleted the TWRP, which forced me to re-stock and re-root. I have not been able to recover with safestrap (not impressed) also, I kept getting gapps failures once up and running (Lollipop 5.0 rooted). My initial goal was to flash resurrection or lineage and now I am finding that most instructions say the G900v is not unlockable and I feel stuck. Would you mind sharing with me what your method was or point me to a link that you followed? - I think my chipset started with 11 (as opposed to 15) if I'm using the proper terminology.

Install non-carrier ROM

Hi All,
Complete noob here, so please be gentle!
I recently bought a new, "unlocked" LG V20 from an auction site.
The trouble is it came with AT&T carrier ROM, which being in the UK and not on AT&T means that it's stuck with the all of the branding and no access to updates.
Build number: NRD90M
Software version: H91010I
Android security patch level: December , 2016
If it's at all possible, I'd like to flash it with a generic non-carrier LG ROM, but unsure of what ROMs are safe to use on this phone, or exactly how to go about doing it.
I've looked at lots of forums and Youtube videos, but many of the links I've found are broken, or the instructions assume a level of previous knowledge that I don't have.
I'm not looking for the very latest firmware, or any trick customisations. I just want a phone that doesn't annoy me!
Can anyone advise what ROM to use, where to download it, and step by step instructions to install it without bricking my phone.
TIA

Being on 10i dirty santa method may work
I always stayed with stock rooted debloated roms on the V20. Most all the custom roms don't support the second screen or have something else I just didn't like.
I have a stock rooted Oreo thread in the developer section that I used for months until I got the PH1 [emoji16]

Use dirty santa, to unlock the bootloader and root, then you can flash 996 rom which should be unbranded

Try Super Rom. It's bare bones. No bloatware from LG or ATT.
Follow the steps here to flash TWRP https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500. I'm having trouble with backups fully restoring, but it works otherwise.
I'd imagine you could install Super Rom right after you can access TWRP, but I haven't tried it. I did it after flashing 10r.
Download Super Rom and put it on your SD card. Flash it after wiping everything https://forum.xda-developers.com/v20/development/rom-superv20-h918-t3764390. During the installation, it will ask you if you want to flash a kernel. Select mk2000. The speed difference is astounding. It's slow and lags without the kernel, but extremely fast if you include it. Boot system and set it up. Then go back to TWRP and flash SuperSU for root.

Wrong! Flash root immediately after you flash the rom

You can just flash a US996 KDZ using patched LGUP, unticking modem. Don't accept OTA updates though
Thanks all,
Not been ignoring you - just crazy busy.
So if i understand correctly, the 996 rom will give me a stock, unbranded V20 with the 2nd screen working?
Is there any particular version of the rom to look for, or any to avoid.
TIA (again)

I posted something else here, which wasn't relevant.

Just flash the newest US996 KDZ, don't worry about modem (they're both GSM only devices, so US996 modem should work on the h910, and it'll also change the unlocked-bands to US996). Use the patched LGUP from this forum, it allows cross flashing
