[ROM][OFFICIAL] Lineage OS 18.1 for Pixel 4 / 4 XL

Search This thread
What's happening is the google bug, that sometimes when I reboot my phone, icons go missing. App icons are all there in the correct places, but any shortcuts I've put on the homescreen that point to web pages disappear, shortcuts I've made using the google drive widget disappear, and shortcuts to local folders I've made using Mix Explorer also disappear. The only thing that remains after a reboot are app icons, and widgets that occupy some screen space, like the calendar, keep task list, etc. My biggest complaint (and this is a complaint against google and I'm just trying to find a way to not recreate them) is my web shortcuts - I have 20-30 of them on my screens and replacing them is very time-consuming. I'm thinking of just creating a webpage on my server with all my links so I can just go through one-by-one clicking, adding to homescreen, etc.. It's not a LineageOS issue, I just brought it up here because the initial searches I found on the web blamed Trebuchet launcher, and then multiple people pointed out that Nova Launcher would fix it via backup/restore..
ah got it! Thanks for the detailed explanation, and yes, I am sorry to say but neither NOVA nor Google can (or would) back those up. Those are all custom settings outside of normal app backups, plus you have noted multiple apps so no one app will backup all settings across multiple apps (out of the box). I am not saying you can't build, or script something that does it for you (because thats exactly how I do it), but not with NOVA or Google. You'd probably be better off making a few backups, then restoring each app backup one at a time (nova / mix explorer / + you also have mixed in system settings) so I few issues right off the bat. I can see at least 3 different services (probably more) that would require a specific backup to restore those settings (thats even assuming mix explorer can backup/restore), but you have to many variables in the mix for any single backup to succeed.

If this were me, I would reverse engineer it, one by one, and backup/restore/test what app handles what setting, then list it all out and know what needs to be restored, in what order, that way its not lost. This is of course assuming all 3rd party apps you are using to create said shortcut, can do this (backup settings).

For me, to not lose any custom locations (network/local/laptop/SAMBA/ETC), I use FX Explorer with root and paid add-on (not needed), then I create my shortcuts within FX, and use Tib (Titanium) to backup JUST FX. When I restore the FX app/data, so does the custom shortcuts within FX. This is the thinking I am getting add with my comment above.
 
Or better yet, Google could fix the bug that erases icons when you reboot, lol
lol but keep in mind, I don't have that issue whatsoever. I have NEVER lost an icon, shape, location, name, nada and I reboot when needed. That being said, again, I don't feel its solely due to Google but multiple other parameters that could be bugging out Google (or NOVA since thats your launcher).

Google positioning/icons appearing wont come as much into play (as NOVA would), if you are using NOVA as your launcher. Most likely you have NOVA set as the default app (launcher) so this is what's holding the positions so we should figure this out first. I don't know what else you have in the mix, but I move between ROMs all the time, and reboot without ever losing an an app or anything about the app (location, name, settings, ETC). I truly do feel something else is at play but IDLK what yet because I don't know your process.

All that being said, I need to ask, is NOVA your default launcher? If not, set it and test a reboot.

Yes, nova is my default launcher. That said, the same thing has happened on both nova and trebuchet, people on other roms/phones have reported the same thing, and I think Google has acknowledged it as a bug. Their solution is to do a factory reset, but I've heard some people say they did a factory reset and had the issue repeat itself afterwards so I'm not inclined to reset my phone occasionally in order to hope I can save my icons, lol. I feel like somewhere there has to be a database or XML file or something that describes the home screen layout that I could just back up occasionally and restore if it happens. This phone is my daily driver so I try not to play with it too awfully much. I'm rooted with magisk, still on A11 (A12 people still have the issue as well). I have not removed trebuchet yet, by the way, but Nova is my default launcher.

show me the references to the google bug you mention please, I am not saying its not one, but I want to review it so I can elaborate on what I meant. There is no Google bug with how I use it, thats my point (and what I mean), and I switch ROMs weekly, A11 / A12 / LOS to anything, and NEVER has there been a hiccup. I am curious if there is an issue I don't know about, but I don't trip it with how I use it.

Don't remove the default launcher, just set NOVA to default in app/settings/defaults. If you remove the default (or freeze it) you may have switch (recent) failures to launch
 
I read it but unfortunately it didn't really go into details on the launchers used, or stock/LOS ROM, or the "missing" icon/shortcuts (other than things like web links). Custom links and map shortcuts are not meant to be backed up with normal Android means, so they wouldn't be saved. The problem is I don't understand what you are losing, other than custom shortcuts that should/would be lost (as they are custom), plus it looks as though this is a STOCK firmware issue (but we are on LOS) and I have never had this issuer so something else is causing it, but not NOVA or Google backups.

The link you sent doesn't really line up with what I expected to see/read/find. For example, I had expected to see something along the lines of a bug post, Jira comment, GitHub tracked event, something bug related (with ROOT cause / solution), but not a random loss of custom shortcuts made on a stock firmware.

I don't really know what to say (because I cannot grasp what you are doing and losing based on what I have in front of me). I still do not think this is NOVA related, or Google backup related. Those do what they should for me, so I can see both apps 100% work as they should for me on my side, so I have to assume its something else going on because I cannot reproduce it (or find anything online as a tracked bug). I only find random bits of custom made things that are lost, but who the hell knows what was done, or setup, not setup, backed up, or not backed up, ETC., this to me feels user related (meaning its probably coming from something we are doing to cause it but not system related).

I installed this ROM and i am super happy so far. However: My PayPal app (newest version crashes, older ones work just fine) crashes when trying to open the app.
I cant install Netflix via Playstore, as it says "incompatible device". I guess thats because of an unlocked bootloader? Same for PayPal probably.

My question:
Could i fix these issues with Magisk? If so, how do i install it now?
Sorry, thats my first custom ROM in ages :D
 
Yes you can fix both, your problem is safetynet and Google play seeing it as uncertified. Fix safetynet, then wipe play store data, reboot, try again and it will work. The key here is SAFETYNET, you must pass SN to get NF (and those types of SN checked apps) to show up as compatible once passing SN.

Install LSPosed (zygote), then install the universal SAFETYNETFix, then wipe Play store data, reboot, test SN and give it an hour (maybe less l and NF will popup. The trick is SN passing, and being seen as certified in Play:

I don't know what happened but my reply above this post, didn't reply to your comment so that was intended to answer your issues.

When I try to download 18.1 it is not available, how does one get this build ?

Official LOS stopped 18.1 a while back, hence no DLs, move to 19.1, its flawless and updated weekly. Its my DD for most of my pixel's true use (meaning I test/try all ROMs) but LOS is my go-to DD (19.1 A12).

FYI though, I did test the unofficial G-Drive link and I could DL it, but its unofficial so use LOS official 19.1 if you want a constantly updated (weekly) ROM:
