Root and TWRP After 20i Update - T-Mobile LG G4

Hi all, new to the G4 and had a quick question. The day i bought my G4 the MM update came out and updated overnight. Im looking to get root and TWRP on the 20i update and I'm having some difficulties finding a guide on how to accomplish this. I have read through autoprime's guide on how to OEM unlock but I'm not positive that it applies to me in my situation. Can anyone verify that his method will work on a stock 20i ota rom? Thanks in advance!

i echo this request. any help much appreciated

Downgrading troubles ZVA->ZV6

Hey guys,
First off, i thought I had already posted this question but I can not even find it in my ousting of posts. So I want to apologize I advance of this ends up as a duplicate.
I currently have a Sprint LG4 that upgraded to ZVA and I lost hotspot. Trying any method to downgrade, fails. Using LGUP fails with "SPC code does not match." and LG Flash Tool says error at DoDownload and nothing other than a code, 00000064. I have also tried the method using systemZV6.img and dd via SendCommand but nothing happens at all with that one after i press Enter and wait a few his.
I have tried various USB ports and all drivers I could find on these forums. Windows 7. Any other info I can provide to help you help me? I am no stranger to flashing other phones, but having no luck here. Searching the web hasn't turned up any help. Thanks in advance.
Is the phone bricked now? You can't downgrade from ZVA to ZV6, because the qfuse version is different.
Thanks apparently i missed that one somewhere as a search via duck duck go never gave turned up results that stated so. In fact the last posts of http://forum.xda-developers.com/sprint-g4/general/how-to-free-mobile-hotspot-root-t3165049/page16 led me to believe it was possible.
Fortunately it is not bricked. Thanks for your reply.

Since it is not bricked, you could probably fix it by flashing the ZV9 update. I don't think there is a tot for ZVA yet, so you might possibly have to wait until there is one available.

if mine is ZVA, can I use the path ZVA -> ZV9 -> ZV6 to downgrade to ZV6? I mean using LGUP.

I don't think you can even use ZV9. I know I said you probably could, but I forgot that's the whole reason you're here; because the qfuse version is different. You will have to wait until a ZVA TOT is available.
I could be wrong, but I'm not a dev. At least be thankful your phone isn't completely bricked.
I just downgrade from ZVA to ZV6 using LGUP. Just the first boot take more time than usual but I did factory reset and everything fine.
qfuse is not different. It should work fine.

Can you give more detail? I have used the TOT and instructions from http://forum.xda-developers.com/sprint-g4/development/restore-sprint-lg-ls991-zv6-tot-t3213196 and always get an SPC does not match error.
Having issues as well. ZVA>ZV6. When I dl the tot file and run it in LG up it says it's not a valid tot file. Also tried the LG flash tool method and get an error message. Any help?

Anyone try to update back to ZVA after root?
Once rooted you can't use the OTA updates because they will fail. They check for that kind of crap. Sucks, but you're stuck on ZV6 with root until the devs work out a bootloader unlock, which may take some serious time. LG sucks major donkey balls because they have some pretty secure bootloaders, now. The best thing you can do is stick with ZV6 at the moment. I know, I know, security patches! Marshmallow! Still, wait until they get something worked out.
Thanks, i figured. Only reason i ask is because im having an issue with mircast. Not sure if its because im on ZV6 or because im on UltraPop..
So we downgrade zva to zv6 or not
Can anyone successfully downgraded to zv6 if YeS so how

you need KDZ and LGUP. look here. i know 10n its lollipop
20i its marshmallow and latest its 20o. are you planing on rooting and use twrp.? if not you can only root 10n with locked bootloader. so you need to stay on 10n.. or upgrade to 20i MM. but do not flash 20oMM and go back downgrade to 20i- or 10n it will brick phone.
you need drivers-LGUP and KDZ. i think in the links you find everything

Root on 20r

I've been searching the forum for a while, but most of the rooting guide are based on earlier version. Do i need to downgrade before rooting?

Yes you would need to downgrade, but since you have a T-Mobile version it's most likely not possible due to anti rollback

yes, same thread, just do the steps about OEM Unlocking and Root. i would grab the most recent twrp image from here (3.1.1-1) and the latest SuperSU here (2.82 TWRP Installable Zip)
you will also need adb and fastboot tools on your pc, get that here, latest version is 1.4.3
or you can just flash twrp and then flash an already rooted system image for 20v from @MicroMod777 found here

yes since 20i-20o-20p-20q-20r-20v all are the same. procedure.. we use the 20i procedure it came first.. BUT dont flash 20i when it ask you to.. since you already in 20r you will be doing this same procedure in 20r so step that says to flash 20i skip you have 20r firmware already... make sure you have LG drivers and for fastboot i used mininal fastboot adb.

I'm new to rooting and I would really appreciate it if someone could tell me how i do it step by step .
I'm not completely lost, however i really don't want to brick my phone as i don't have any more money for a new phone
Check here: https://forum.xda-developers.com/p10/how-to/guide-magisk-v15-4-oreo-t3759998
Be careful with other root methods, I read several sad stories about bricks from users who tried to root.

FF is pretty safe since it only tricks the original updater. All steps are clearly described by the OP in this thread (Step 4): https://forum.xda-developers.com/p10/how-to/huawei-p10-debrand-rebrand-update-guide-t3691013
Need to unlock your bootloader first and install TWRP before rooting your phone.
