[LG V30 Guides, News, & Discussion] JonnyTrulove:
First I just want to say, awesome job here!

Ive been having a couple of issues with my devices since the conversion so I am ecstatic about this. And thanks for all the hard work you guys put into this.

Couple of questions for anyone that has already done the conversion back to LS998. (sorry for some overly noob questions, but this is my every day device and I would really like to knock this out quickly and without a hitch. Thanks!)

1) So in the first post it says Fastboot will still be available if you flash one of the two updates. Has that been confirmed?

Im only asking because back when I was trying to get my bootloader unlocked when my device was still a LS998, I could not access fastboot, so I thought going back to LS would cause the same issue with sprints variant finding a way to block it.

2) Do we know if theres any reason to flash the one with the May security patch vs the one without it other than the obvious reason of it patching some security flaws? As far as we know, are there any games, apps, carrier related provisioning or features that check for an updated security patch in order to run properly or give you access to things? And if not, is there any potential downside to using 21a with the May Patch?

3) Regarding my current apps, data, etc on my device, in step b. "wipe date".

That will overwrite everything on the phone right? And assuming it does, i make a back up in step "a. Make a backup of System, boot, and Data before proceeding" , but I think thats just a safety back up, In case all goes wrong or something doest work. So I wont be able to restore any of those three back to my device using twrp after the conversion. So whats the best way to back up my current stuff and restore to the new variant without creating a bunch of issues due to the variant changing? Titanium backup? LGs back up and restore service? Restoring just certain partitions with twrp and doing it that way? Also, will wiping the data wipe the SD card or can I safely leave the SD in during all of this and flash the file plus magisk rtcd and so on and not worry about losing the files?

4) On the US998 I havent received a single OS or Security update notification but all I did was disable the LG ones and the deactivate the slider for auto updates in Dev Settings. Wondering if now that I will back to a LS998, do I need to worry about / disable sprint OTA updates? Can they possibly break root?

5) I disabled LGs root checker through the DEV settings. I did this after my phone was already rooted and had installed the patch at the time of installing twrp and I never uninstalled the patch or anything like that. Anyone foresee any weird issues there? Like i should reenable, or patch again after the flash just to be sure?

6) I have used MyAndroidTools to modify/add-to/cripple some of the system applications along with a whole mess of other things I have tinkered with through either various programs, command lines in ADB, Shell commands, or editors. I honestly have no idea what bits of these would stay modified vs what wouldn't and so on. So i am curious if theres anything i could have done or setting i could have changed that would negatively effect the outcome of me trying to reflash the variant completely. SO any thoughts or insights there would be great.

7) This one is a weird one. My device is rooted with magisk, twrp recovery and bootloader is unlocked using the Frankenstein method and the root methods here on XDA. However, at some point in the last couple weeks i noticed the slider button for Enable OEM unlock in my developer options is not grayed out anymore. Its still set to on, and hasnt changed, but it very much looks like i can change the setting. I have not ouched it out of fear that just toggling it would throw the system into a weird conflict loop and brick me. I dont know if I overrode a setting playing around with something or what, but this has kinda been freaking me out for a bit and now I am a bit worried it may cause an issue when trying to flash this.

8) Magisk Modules, System Apps etc. Has anyone run into issues with Magisk Modules or apps that have been converted to system apps? For example, I have the google Phone and Contacts Module running through Magisk and it put the phone in as a system app. I am wondering if I should uninstall all these kind of modules or modified system files before doing this flash, just in case it cause some weird orphaned files issues that will be difficult to figure out or fix later.

Thanks in advance for any help with some of these answers!
