Best practices upgrading & downgrading - Nexus 6P Q&A, Help & Troubleshooting

It has been some time since I got my 6p and settled with CM 13 as my daily driver.
But I am not totally happy with it and would like to try some of the newer roms.
However, I got a bit confused when trying to read up on the ins and outs of upgrading, and if needed, downgrading.
So, the most prominent question is, can I just flash a android 7 custom rom after wiping my android 6 rom?
And can I get back to my 6 rom if the 7 does not work out?
And, would installing a 7 rom wipe my internal storage? (the forced encryption thing makes this even harder to wrap my head around ; )

Flashing a Nougat ROM with MultiROM from 4.4.2

Hi all,
I just found my old Nexus 7 (2012 model) in a dresser drawer and decided to bring it up to speed. Currently it is running what appears to be a stock (maybe debloated) 4.4.2 with root and multirom. Recovery is TWRP for multirom. I was using multirom to run Ubuntu just for kicks, but have lost interest in that project, plus it now appears to no longer be supported. Now what I want to do is just flash one of the nougat based roms and call it good. When I try to add nougat as a second rom I get errors relating to E: not existing, it then deletes everything that just started to install. Posts I've seen in other hardware forums point to maybe the install script being wrong for multiboot. Is there any weight to this idea?
I want to run one of the new roms as a secondary first to see how well it works before flashing it for good. Am I missing something stupid here? I haven't messed with any of this stuff since I switched to Verizon and could really use some help.
I don't really need the multiboot option, but since I've gained it I'm a little slow to want to give it back up. Would it be easier for me to just reload the bootloader, recovery, etc, take it back to stock and start over?

Is the support of Multiroms dead or do they plan a patch for nougat later when it get more mainstream? I am currently running dirty unicorn 7.0 since I just got my screen and would like to have older build for compatibility issue.

If you wan Android 7 on your Nexus 7 2010 you can't use MultiROM: https://forum.xda-developers.com/showthread.php?t=2011403&page=316
Without MultiROM you can use this Android 7 ROM: https://forum.xda-developers.com/nexus-7/development/rom-lineageos-14-1-nexus-7-2012-t3530261

10 GBs Space missing on MotoX Pure

Hello.
I have a moto x pure running android 6.0 bootloader unlocked and rooted with TWRP recovery.
I keep encountering a problem with my internal storage there are 10 GBs of space missing. I need to wipe my data and reset the phone every couple of months for this issue any idea what's causing it and if there is any soulution other than wipe the device. Attached are some screenshots of the issue with the device info
Same thing was happening to mine and I didn't have a solution. I recently installed a new rom and the data went away, however I never actually found a proper solution. I had 13 GBs taken up by 'system' for seemingly no reason on the stock rom. Sorry I couldn't be more help, just reporting that you are not alone.

Unfortunately I can't suggest anything, I was using this phone from stock since I got it. I just now started to install roms on this device so I don't know all of the options yet. However some people state that LineageOS has the 'chop chop' to turn on the flashlight. However the 'wave your hand over the screen for it to turn on' feature is missing on my rom (crDroid) and I assume any rom that is not stock. I believe that most custom AOSP roms will not include most moto features. You should look for roms that are build off of stock, they will contain all the features of the stock rom as well as 'custom' features from AOSP roms.
Edit: After looking through the roms for this device, it looks like this is the go-to 'stock' custom rom TruPureX If you want all the moto features, but still want extra stuff, this looks like it would be the best bet.
I can't see any problem on the screenshots...
You have
7,94 gb Android OS
5,20 gb Apps
6,75 gb Images
0,95 gb Audio
1,67 gb Other
That summed up gives 22,51 gb off the internal memory
The device shows 22,90 gb used, the 390mb left is caused on cache/dalvik-cache/odex stuff i did not add there
Forget about what i told you, i was wrong on adding the Android OS :silly:
I've never had this problem, mine is working properly (or not, since it shows less than the total sum)

What ROM should I get to keep now-defunct Nexus ! running?

I suppose this is a reasonable place to ask this sort of thing and hopefully avoid 'how-long-is-a-piece-of-string?' replies.
I have two of them - a 16 and a 32 GB - and they seem to be OK for the most part. They are used for usual non-commercial stuff including video watching and some mild games. I just want the Nexii to be as stable, efficient and hassle-free as possible.
My options seem to be to run:
stock 5.1.1
A marshmallow ROM (which one?)
A nougat ROM (ditto)
Any of above with Franco kernel for efficiency and maybe Xposed, if available, for tweaks and 'upgrades' e.g. 'N-ify'.
I currently have PureNexus 7.1.1 on one (no camera) and Cyanogen 13.0-20161031 nightly on the other (some freezing and crashing).
Any suggestions re what I could use that is as stable, efficient and hassle-free as possible?
BUMP. (does one need to do this on XDA?)
I might be at the wrong forum sub-group. Any suggestions where I might find folk who know about mods and Nexus 10?
Ultimately, _no_ 7.x ROMs have working cameras, and I don't think any of them have working DRM binaries either (although I could be wrong).
CM is no longer being maintained, so any issues you do have there are not going to be fixed.
There is the LineageOS 6.x (https://forum.xda-developers.com/nexus-10/development/rom-t3556116) but whether it works well I don't know. It appears to be the closest to a 'maintained' 6.x ROM though.
I was just given a 10 last weekend and went with the latest lineage build https://download.lineageos.org/manta
Assuming you have a custom recovery just wipe, flash lineage, then a small gapps package, and finally SuperSU and you are rocking and rolling. Just give it a few minutes to settle after the first boot. My only complaint so far is the lockscreen is only in landscape mode.
Many thanks for your reassuring replies,vo4LG and someguyatx.
Once I get over my current f#up - I upgraded TWRP to 3.1.0 not to recovery, leaving me only able to boot to TWRP in recovery - I'll be going to Lineage MM. Somewhere else Resurrection was suggested. Maybe I'll put that on Nexus no.2 afterwards.

ROM question: Upgrading on old OP5 with Android 6 to 10

Sorry in advance if this is a dumb question but I have an old OP5 sitting in a drawer that I'm not using anymore- it's already rooted and running a custom Android 6 ROM that I had flashed.
I was going to give it to a friend but I wanted to flash an Android 10 ROM on it for him before handing it over (he doesn't know how to do this stuff).
I wanted to know if I can wipe the phone, flash a newer version of TWRP and then either OOS 10 or a custom Q ROM, or if I have to flash it to OOS 6, then 7, 8, 9 before I can put an Android 10 ROM on it.
I vaguely remember going 2 versions up on this device before (possibly back in the lollipop era) and if I recall correctly I had to flash the next Android version before flashing to the version after that in order for the custom ROM to work, but it's been a long time. Thanks in advance for any wisdom you can offer.

Twrp for 11?

Hey guys,
Anyone have any info when either unofficial or official twrp is coming for Android 11? I made the mistake of upgrading to 11 from 10 then tried flashing twrp which bricked my phone ( I fixed it, no biggie ). I just really want to flash a custom ROM and I can't find any other custom recovery that will do that and side loading twrp also gives a crashdump error. Unless anyone knows how to downgrade to 10, the the furthest downgrade I've achieved is 11.0.0, once I hit 10.x.x I get either a black screen or crash dump.
It's a lot there, I know. Much appreciated everyone.
Edit: reading more on this forum, I think I found a way to flash a custom ROM on Android 11.. I guess you can side load roms? So I guess I'm going to give that a try. I'm so old school, like back in 2011.
I had the same problem. Im using the Lineage recovery atm an idk why tbh. I think i used it for rooting and for now im only using magisk modules to obtain some featurers.
Sideloading roms is a thing but man i miss those old HTC Hero., HTC Desire times. Last years i was using a P30 pro without root and im so happy to have root again.
Anyway read carefully and have fun. I would love some answers from your experience here.

Most custom roms include all the files needed to flash the entire rom from a batch file. CrDroid for sure, but also Lineage. I'm sure there are more. My issue is not flashing, it's that all important nand backup from TWRP I miss the most. Switching roms is a lot more tedious when you have to re-install everything to revert back to your old setup.
Twrp for 8 and 8 pro may not happen ever, encryption is the problem
TWRP doesn't look promising considering the time that has passed since 8 launch...
