[G2 Q&A, Help & Troubleshooting] jamaljamal2:
==================LONG NOOB WARNING============================

Hi!

Recently I've just installed Lineage OS 18.1 on my phone

Phone: LG G2 (international[D802])

Current build is: lineage_d802_userdebug 11 RQ2A.210405 cd6fb8d05d ( lienage os 18.1 2021.04.29 Nightly )

So first I've switched from the original os (Android 5.0.2) the steps I've done:

1.: Rooted my phone via LG One-click Root what I found on the internet (https://www.dropbox.com/s/2shvozzbu29xjfu/LGG2-D802-OneClickRootRecoveryV1.1.zip?dl=0)

2.: installed TWRP recovery with TWRP manager (https://play.google.com/store/apps/details?id=com.jmz.soft.twrpmanager&hl=en), (https://www.gregtwallace.com/lg-g2/g2-twrp/?version=3.3.1-0#download-section)

3: downloaded Lineage Os build 18.1 20210422 and BitGapps

4: Installed both of 'em.

After these, I used my phone and I was happy, (i switched the recovery to lineage as it came on screen I didn't know I'll need twrp in the future) but just as soon as the newer (my current) build came out it notified me, and I started downloading it through the built-in updater (settings-system-updater)

First, it appeared to installed normally, so I basically left it to do its thing, but it turned out it won't boot (Couldn't load android), so I tried to install it again with ADB via built-in lineage recovery, it said it was successful, however, it didn't load so I formated the data within the recovery, and it immediately booted into the system. Now comes the part which i need help in (i wrote all this down to get a better view of the problem), so after i booted into LOS i noticed, that the gapps are gone.

I thought ok, it is how it is, then let's try and install them. So i downloaded the minimal ADB and fastboot program which as far as i know is enough to do simple installs. So i fired it up, went into lineage recovery and clicked install update with ADB (or however it is called, can't remember that ), and i wrote in the console ' adb sideload <bitgappsxversioncan'tremember>.zip' and it started to install but got me with:

"finding update package...

update package verification took 2.7 s (result 0) .

"

I took my time to make sure it's the right version (it is arm as my device run by arm, and it is R as Android 11 so i think it is for my os)

I'Ve thought ok, then maybe i'M doing something wrong, so why not just wipe all and restart again?

I noticed i have no root permission, so i have to get one, now as i know (correct me please if i'm wrong) LG oneclick root is for Kitkat and lollipop and stock firmware (?), so i looked up the internet and saw that lineage has removed the super user (root) option from the developer and have to install and addon (su package) to readd it. i thought, aight' let's do it then, i downloaded it and tried again via sideload on adb and from internal storage too (addonsu-16.0-arm-signed.zip), but the result was similar to my previous attack with gapps except it said

"

installing su addon...

set_metadata: Error on lstat of "/system/etc/init/superuser.rc": too many symbolic links encountered

E: Error in /sideload/package.zip (status 7)

"

Apart from these Lineage runs great, except hbo go wont work for some reason (chromecast library cant be reached or so), but I'm okay with that, and a huge thank you to the developer for the os!!

so my questions are:

Either way:

-can I root it somehow to be able to install TWRP, and start everything over and get Gapps?

- Can I install Gapps somehow without reinstalling recovery?

-in the official TWRP app there's no d802, which one should i download, or even should I download any different model (like American or d800,d803, etc.)

Apart from the previous question is there a way to upgrade lineage without losing data? (i read somewhere that sideload should be my choice is it true?)

Thank you if you've read this far, if you know any solution for me please share with me, I'd be really grateful!

have a nice day!
