Possibly it would be a good idea to detail the current ROM installed, and any MOD's. I'd also go and have a look at Settings > Battery > Battery saver & performance (top of page, bot labelled brilliantly) turn off things like the "automatic optimiser" it might be "the system" is deeming one of the apps is using too much wifi and throttling it. If you were on CM then likely that you were away from college at Xmas, so was there any change in wifi dropping? (that was a rhetorical question I don't want to know your Xmas plans).

You assumed right haha. Yeah, the problem persisted. I'll check it out

Nope, that's not it, I don't have optimization on.

I've looked through all the previous posts related to WiFi drops I could find but there wasn't a solution
[One (M8) Original Android Development] Healtheater:
I had this too, but i think i were able to fix it. Seems the problem only occurs when 2.4ghz wifi and 5ghz wifi have the same ssid. I changed the 5ghz ssid to a different one and the disconnects are gone. I think my phone was constantly changing between both. Sadly there is no option (in wifi settings from LineageOS) to deactivate one of the wifi standards to only use the other one.

Helpful tips for Frequent ROM flashers

As the new update procedure seems undocumented...

Tip 1.

In the new lineageOS they have decide to put in their own recovery image. When you try and install from the updater it tells you "this will only install with a compatible recovery image" but give no further information. Twrp users find that the system reboots but then stops. To install you then need to find the file using the advanced file manager in the directory /data/data/org.lineageos.updater/app_data . (You could always just use a PC and put the nightly ROM on an sdcard using ADB from https://download.lineageos.org though that still means the updater is going to notify you about a new ROM as it's not under that specific directory)

Tip 2.

There is no information about recovery unlike CM that used to ship an option image but...

In developer options there is a setting "Update recovery" on my phone it was off. Clicking on it gives an explanation that turning it on will install a recovery image that will enable updates etc... The downside is that this will remove the twrp recovery image. I will shortly be testing this out with the build from the 31st Jan

Update

As the updater will not reboot into twrp to install an image, it cannot replace the recovery image which I am guessing is the brand new LineageOS recovery. It may also be because my phone is encrypted but a normal twrp installation of nightly cannot then mount system, and I'm guessing the magic happens then. I'll try decrypting it, and also digging out an old CM-recovery to see if that will resolve the situation.

Tip 3.

Also to delete a nightly build once flashed, in the updater long press on what nightly want to delete and it will give you the option.

apps disappear

Hi all,

First I'd like to thank all of you for the ongoing effort to support older devices with custom roms. I am very grateful that I can use Android 7.1.1 on my m8. I flashed the first official as the first custom rom on my Vodafone branded m8. Unlocking the bootloader, flashing twrp and lineageos worked like a charm and I am very satisfied by the performance.

I am experiencing a strange issue though: From time to time apps disappear from my device. I experienced this with multiple apps, for example: Adobe Acrobat Reader, a battleships game, a calculator app. I think there were more but I cannot recall these. As far as I can tell that disappearing isn't connected to a reboot of the device. Usually I never turn off my device. I have no idea what information I could provide for a better insight in this problem but I'm willing to help with the investigation.
[One (M8) Original Android Development] CutGlass:
You know it's funny that you mention that, yesterday the icon for clash of clans just disappeared after flashing the ROM with the latest nightly. The icons on the same screen installed after were in situ, and I thought I'd gone bonkers. Now when you flash did you do the latest open_gapps ? and also if you go to the play store are the programs there? it could be that they are not nougat compatible or have a differing version for nougat and then during the update check that happens normally when you plug in to recharge, the play store might go "Nope that's not right". If you have a backup, backup up now, (be careful SMS message loss is in my experience the most frequent missing thing unless a backup is performed in recovery and not initiated through an app), then you might want to revert to it and grab a couple of screenshots to check.
[One (M8) Original Android Development] morphew:
I flashed the first official 14.1 LineageOS and the latest OpenGapps (stock edition) immediately afterwards. Then I started setting up the phone with my accounts and installed apps (via Play Store). A few days later some apps disappeared. When I checked Play Store I could only install the apps again. The apps that I installed again haven't disappeared since.
[One (M8) Original Android Development] CutGlass:
So there was no dirty flash, it was totally clean and then installed from Play? (that knocks my theory on the head about old versions) How is your sdcard formatted? portable storage or f2fs (the thing that lets you put apps on it an extends your device but can't be used anywhere else).
[One (M8) Original Android Development] morphew:
It is formatted as portable storage. After formatting I copied a backup of my sdcard back onto it. That was before installing the apps. Also, one of the disappeared apps (the battleships game) wasn't installed before on that device.
[One (M8) Original Android Development] CutGlass:
Ok I'm probably at the end of where I can help, we've discounted differing versions of android and possible sdcard corruption. Nothing been moved to the sdcard (don't even know if it's possible when formatted as portable storage). The only other thing I can think of is a rogue memory cleaning/ RAM space freeing app that's knocking out that something is installed. Shouldn't be possible on a non-rooted device, but that's the last thing I can think of and a bit of a stretch.
[One (M8) Original Android Development] morphew:
Thanks for your effort. But there is no task manager / cleaner installed. I didn't enable root and I didn't even try to move an app to sd. :(

I just wiped Dalvic/ART cache and Cache in TWRP but to no success.
[One (M8) Original Android Development] CutGlass:
:( but at least the possibilities have been narrowed down. I think I read on another open source forum,

please donate but

if you can't give money, give advice

if you can't give advice, learn more and go to step 2.

So as I've failed I'm going to boot up a terminal at some point and work out where the log files are for debugging installations if they exist. Won't help you, but in the future :angel:

Also, nothing Big but first post is saying marshmallow instead of nougat ;)
[One (M8) Original Android Development] xdagee:
Yes, you will get the OTA update via cmupdater but it won't install on Primary ROM, it will prompt for an error in recovery when you try to install. What you should do is after the download, reboot into recovery install over the existing nightly.

And from OP, it's right go back and read again you will understand.
[One (M8) Original Android Development] dyfk3l:
Awesome work, as posted in the unofficial thread.

I highly recommend using the official builds with additional flash of Team M8 kernel, it's much smoother than CM kernel:

http://xdaforums.com/htc-one-m8/development/unofficial-cyanogenmod-14-t3490208

Together with some tweaks in Kernel Adiutor the device is unbelievably smooth and battery is great.

Hi, so I tried to download over my fiber provider at home and still have the same problem.

Thanks for your answer, but sadly it did not help. I did formate the SD card in exFAT.

[One (M8) Original Android Development] CutGlass:
Possibly we are getting towards the same area, last night I reverted to a 30th download and then tried the updater at least 5 times before it verified the zip and put it in the location already mentioned. I also downloaded it manually, deleted the file (see a couple of posts ago about tips), put it in place using my PC and it showed up ready to install. I have got a "problem" message because of twrp which may be the same as yours but I have to go out, I also have an old CM recovery image that may be compatible and that the next area of testing. I do suggest you read the tips especially the hidden one in developer options and look if it's there on a 30th install, it brings up a message that implies with the "right" installation then lineageOS has it's own recovery manager in the zip.

---------- Post added at 07:01 PM ---------- Previous post was at 06:58 PM ----------

What capacity is the SD card and have you tried a different one. (also if you format it as ntfs or mac journaled or similar) will it pop up on your phone demanding a reformat?
[One (M8) Original Android Development] CutGlass:
Right are you at the stage of the attached images (I had 5 minutes between meetings). One is the update then the there shows what happens if I press update. At the bottom of the screen there is "unable to boot into recovery" I have twrp installed. I am intending later to see if a CM recovery image will help it boot in. This is from a 31st January installation so it may refuse to install because of the date and I may have to revert back to 30th to test.

[One (M8) Original Android Development] CutGlass:
No, android pay installs and takes the card but then says that it's not NFC compatible with payments, so I think it's a matter of getting the NFC working, even when on there's no icon in my nightly from 31st.

Hi, because these issues are affecting multiple devices the thread was move to https://xdaforums.com/lineage/general/p-lineage-operating-t3528558/page21 bottom of the page is where the discussion starts. It gets quite in depth over the next page.

Basically it makes not difference whether twrp or cm recovery is installed, everything fails on either encrypted or unencrypted devices. There is a recovery image in the 31st nightly zip but it's linked to an installation script that twrp does not trigger, so tomorrow I will investigate further.

---------- Post added at 01:42 AM ---------- Previous post was at 01:13 AM ----------

Well screw me sideways. After many re-installs, dirty flashes, wipes and everything attempting to debug the updater not triggering twrp and seeing if an older CM recovery might work, I finally gave up and went back to my full back up before all the experiments. Guess what? The Clash of Clans Icon has gone yet again, randomly disappeared, I put it back after the last time, so your app issue ? I do believe something is going on, that backup should have been entirely static no changes, even the last SMS messages I received/ sent just an hour before are there, but the icon "poof" and it's gone. Something is certainly going on in the background. I know the icon was in the backup because I had to decrypt my drive to do the testing and re-installed it to confirm before I went ahead with another wipe and tests. At some point in the last hour some process has removed it and I've just noticed there are two other gaps on my screen.

Bugger me, it's now not just the icon, I have 3 apps that have just disappeared. Two installed yesterday, one last week. I suspect there's some kind of corruption in however lineageOS keeps track of installed apps.

Reboots when trying to pair to bluetooth

First, thanks for all the work on this ROM. I am thankful that I can continue to use my M8.

I have clean flashed the Jan. 30 ROM - nightly, not experimental.

I use TWRP 3.0.2; do a restore to factory wipe, and clean flash the ROM, with micro GAPPS.

Everything works as it should until I try to pair with any Bluetooth device.

Once I attempt to pair by going to the Bluetooth settings page, it times out without finding the device. When I refresh so it searches again the phone restarts.

Is anyone else having this issue?

I have gone back to a pre-lineage version for now so my Bluetooth devices all work again.
[One (M8) Original Android Development] CutGlass:
Using the build from the 31st Nightly (experimental is a transition ROM once in nightly or clean flashing nightly it's not to be used), I've just hooked up to a set of never before paired Headphones (volume is dangerously load, I suspect that the max vol settings in developer options is not working correctly) and bluetooth worked fine in my car for making and receiving calls. Sorry :(

---------- Post added at 07:56 AM ---------- Previous post was at 07:42 AM ----------

Actually I will just give you further details of my config, device has a PIN lock, when paired smart lock came up asking if I wanted the device to be permanently unlocked. Headphones were still working without smart lock on, then when activated they still worked. Headphones are A2DP bluetooth 4.0 spec mid range AKG Y50BT. Audio FX works throughout the range every function, music is very accurate, sight hiss click when turning on and off music, this is by comparison to a MacBook Pro that hiss for a long time when making a connection.

Nearly, my installed one is from 27 January of the unofficial from TeamM8 and I also see the nightly of the 30 January. My phone nor my SD card aren't encrypted.

Update OTA from 30 and 31 January now says "Update download was unsuccessful. Verification failed. Corrupted or unsecure download." and /data/data/org.lineageos.updater/app_data remains empty.

Update over PC from 30 and 31 January (Md5sum Check ok) throws error: "Zip signature verification failed!" and without the verification I get "Updater process ended with ERROR: 7"
[One (M8) Original Android Development] CutGlass:
May I suggest that you flash experimental from https://download.lineageos.org/m8 from the 30th Jan using twrp, reboot into the OS which gives you an awful overlay, but the twrp the nightly from the 30th, which then should give you the updater for the 31st and don't install TeamM8 :mad:

I'll expand on that last comment. Team-M8 as a project has not released an official for nearly a month, their kernel is dated from November prior to at least two security patches on AOSP. I am still trying to get an answer from a dev as to whether the security updates were static or loaded into the kernel (I suspect that the kernel is monolithic and therefore the updates will not have been applied). I suspect your problem is that official lineage is not recognising the unofficial kernel's either by MD5 or whatever.

We (here) were using [MENTION=5226211]cmattern[/MENTION]'s excellent nightly builds but still had to go through experimental and he stopped about the 25th before the release of the updater so it is not surprising that you are getting failures. I think I may have seen the error 7 before, when i tried a dirty flash over cmattern's unofficials (he repaired the encryption, a file went missing in official, had to revert to unofficial, the file was found and I thought I could shortcut).
[One (M8) Original Android Development] DATA78Lux:
Many tx I'll try that, if not I'll do a full wipe and do a clean flash :) Titanium Backup always was my friend before ;)
[One (M8) Original Android Development] DATA78Lux:
Yes, I could install the experimental from 30th Jan but I still had to disable zip signature verification to get it done.

After reboot to OS I started the OTA update to nightly 31 Jan which informed my for the install I must use manually mode.

Then again to Recovery I could find the OTA download in /data/data/org.lineageos.updater/app_data but could install it Error 7 after disabling the zip signature verification.

I then successfully installed the PC downloaded nightly from 30th Jan, but again only when disabling zip signature verification.

Finally I rebooted to OS then back to Recovery to install nightly from 31th Jan, yes you guess right, only without zip signature verification.

I'm curious how it will work with next daily :)
