I already have CM7 on my Arc S, and been trying to update to CM9, but I don't get past the boot process. I read through the Arc S development thread, but some questions remain:
1) can I update without losing the apps and data I have currently on my phone? or do I have to wipe data, system and cache to update to CM9?
2) do I need to flash a new kernel through fastboot, or will the current one I flashed for CM7 work?
thanks.

Yes, use Titanium Backup or similar.

Yes.
and ergo I also have to wipe data and cache partitions? do I also have to format again?
thanks!

Yep.
I just finished rooted my Verizon G4 (which by the way doesn't wipe any data and took less than 15 minutes). What I'd love to have is Xposed though, is there any update on either Xposed without TWRP, or getting TWRP on our Verizon G4's?
I just want to confirm -- it doesn't wipe any of your internal/sd card data?

As I said in parentheses, no it does not wipe any data.

No all my apps and settings were there after flashing the rooted tar. Root stays after a factory data reset too.
Where is this root, of which you speak?

Hi,
Running stock LG G4 with official marshmallow. I have a problem with my cmaera videos coming out juddery. I want to wipe my phone but i want to wipe the cache partition. My G4 has the built on lg recovery which doesnt give me that option. Any way i can wipe the cache partition without voiding my warranty or rooting my phone?
Any help really appreciated

Thanks for the reply. So once ive installed twrp and wiped the cache partition, could i delete twrp off and then lg wouldnt know it was ever tampered with?

Once the device is unlocked (if yours is able) you will lose warranty and cannot restore bootloader to default.
Hi! I went into the latest TWRP recovery with unlocked bootloader, and I wiped system, cache, dalvik and data. Then I flashed the proper vendor image, the ROM zip, Gapps and then Elemental X kernel. However, when I reboot, it just boots me into TWRP recovery. I have tried wiping dalvik cache and cache. I then tried restoring a nandroid, but it just got stuck on the Google screen. Didn't even get to the colored dots screen. I ended up flashing factory image, but I would like to get my Nandroids working and this ROM. Please help! Thanks
I'm no expert but I think it might be happening because of encryption. Did you disable encryption before doing all this stuff?

Encryption in stock Android? As far as I know, I can't turn it off. It says that the device is encrypted in settings. I think nougat forces encryption.
Unless maybe there's a patched kernel that can do that?

I dont think is your problem , im encrypted and never have issues with twrp! Never!! What version of twrp you running? Theres an unofficial kicking around that is much better than official! Maybe you got a bad download! I would redownload all, find and download unofficial twrp 3.0.2.3 I believe. Let your phone boot before you flash custom kernel, thats always worked great for me. The latest official twrps 3022 and 3021 both have nandroid restore issues as well efs restore issues that could ruin your day
Format data and system (format, not wipe) and try installing it again. Should work
OK, thanks

Only data and system? Not cache and dalvik like the purenexus install guide says?

What's the difference between wipe and format? On TWRP there is only WIPE for all partitions, but a format data button.

Wipe just deletes all data on the partition. Format makes the partition again, therefore it removes encryption, repairs potential problems etc. Format data has dedicated button in TWRP, for formatting System go to Advanced Wipe, check system, tap on Partition details, check EXT4 and perform format.

There is no Partition details button. Just fix partition or something like that.

Repair or Change filesystem? Yeah, it should be that.

OK, I will do that. Thanks Just to clarify, I format data and system, and wipe cache and dalvik?
A Thought
Dunno if this will help, but whenever I flash a ROM/kernel combo, I always flash the ROM/gapps, boot up with whatever kernel is included in ROM to make sure it boots properly, and then after successful boot flash EX kernel through TWRP.
OK, so I formatted DATA and SYSTEM, and I wiped CACHE and DALVIK. I then flashed the proper vendor image, pushing it to the device with adb push, and then adb sideload for the pure nexus ROM. It's currently installing. Then, I will adb sideload the gapps ZIP file. Then I'll reboot and see if it worked
EDIT: It just said "No OS installed"
EDIT 2: Just flashed the ROM again, and it is showing the boot animation. This time I did not do Gapps. I also wiped and formatted everything again. Hope all goes well.
EDIT 3: The ROM booted fine. Glad all is working now

So I had flashed the ROM with no Google Apps or anything, just the ROM. But when I add a Google Account, I can't because it says Google Play Services has stopped. I just noticed that the build number is one of a Nexus 6P, and the vendor image is different, the one I manually flashed.
i updated knox patch to get securefolder working but now it whines about data being encrypted

You cannot decrypt data without wiping the device. It's an Android security function.

Samsung has encryption enabled by default in their vendor
In order to disable it, you have to manually do it with a multidisabler that works for your device.
