Hi,

there is an issue with WiFi when I use a restricted user account.

Sometimes wifi stopps working after switching to the restricted user account.

Then it takes a while to reconnect.

Latest Build ineage-14.1-20170129-UNOFFICIAL-jfltexx.zip

---------- Post added at 10:49 AM ---------- Previous post was at 10:48 AM ----------

Now after reboot phone stucks at boot. I can see al the times the LAOS bootanimation and the phone vibrates all the time.

After a fullwipe and flashing LAOS again phone starts working.

I'm currently running [ROM][7.1.1][UNOFFICIAL] LineageOS builds[Jan 20][jfltexx] made by Side.

Anybody know if it is possible to dirty flash this ROM by BenLue on top of the one by Side?

What about superSU ... is it OK to keep the one from Chainfire or do I have to uninstall and then flash the Official su from Lineage OS (extra)?

Hi @ all,

Now after Flashing lineage-14.1-20170130-UNOFFICIAL-jfltexx.zip the phone stucks at boot. :(
[Galaxy S 4 i9505 Android Development] Buff99:
I've heard this on other lineage ROMs too. Always with a restricted user account, loclscreen gets in a bad state. There is a setup file you can delete in twrp file browser to allow you to get past it. Can't remember file but will have a look...

Ah yeah it was on my ROM LOL...

In twrp edit /data/system/profiles.xml and change lockscreen to default (0?) to stop it happening.

And seems it will happen every time you dirty flash with a restricted account and non-default lockscreen...

Great ROM!!! but I've found the battery drain fast. Any suggestion? which kernel would it be the best to fix the problem?

Thank you
[Galaxy S 4 i9505 Android Development] lekiaM:
In my experience Alucard Kernel, by using Stweaks. Very easy to use. Personally i wouldn't fool around with different kernels. Just accept the kernel who's coming with the rom. Battery life is pure user related and in most cases not rom related.

Also: bin mit meinem S4 i9505 von cyanogenmod 13 auf lineage-14.1-20170131-UNOFFICIAL-jfltexx.zip umgestiegen.

Aber:

ich bekomme am PC keinen Zugriff auf die SD Karte und die Externe SD Karte (am S4 direkt kein Problem!)

- USB Debugging - ist an

- Root Access für Apps and ADB

- USB Konfiguration ist MTP (mitPTP kann ich den internen Speicher ansprechen)

was meinst du mit Root Access ?

geht in dieser ROM Root Access default, Ich las, dass man dazu etwas extra installieren soll.

brauchen wir die nicht und root ist build in ?

what do you mean by "root access" ?

don't we need special software (s.link) to get root access on our ROM ?

[Galaxy S 4 i9505 Android Development] Mitsch79:
Could you boot into twrp and check whether you can find the folder .android_secure on your sd card (using the integrated filemanager in twrp)?

If so, delete it and you're good to go. I had a similar issue when migrating from cm13 to los14.1. I could not access the sd card at all using the

roms filemanager. It always asked for elevated permissions, but there's noone more privileged than root :)

Kannst du mal bitte ins TWRP booten und mit dem Filemanager auf deiner externen SD-Karte schauen, ob da ein Verzeichnis .android_secure existiert?

Wenn es da ist, lösch' es. Ich hatte das gleiche Problem beim Wechseln von CM13 auf CM14.1 bzw. LOS14.1. Ich konnte praktisch gar nicht auf die SD-Karte zugreifen.

Selbst mit dem Filemanager im Rom nicht. Der wollte immer höhere Berechtigungen, nur ist über Root nichts mehr ^^

LineageOS

Resurrection Remix rom is very different from our LineageOS rom

RR does not use the LOS framework!?!
[Galaxy S 4 i9505 Android Development] ErichRc24:
What is LOS framework? And for what works?
[Galaxy S 4 i9505 Android Development] Exodusnick:
Sorry LineageOS
[Galaxy S 4 i9505 Android Development] ErichRc24:
But working on resolving the video camera bug?
[Galaxy S 4 i9505 Android Development] Buff99:
RR 5.8.1 is based on the same LOS frameworks as this rom and every other LOS based rom, with extra RR specific stuff added. RR is really a fork of CM14.1 / LOS.

@side 's code that I use to fix the RR camera is on his github and has even been submitted to BenJule's github (without asking Side) here by Toumz42, but I can understand why BenLue hasn't integrated it - if he adds Side's code then his rom will be identical to Side's...

The current bottom line is if you want pure 100% LOS then use this build. If you want 99.99% pure LOS with working camera use Side's.

The S4 was released with a few different types of modems. The modem is used for both the WiFi and Carrier Connections to the Towers based on the frequency that carrier uses for its towers.

Look for your devices Baseband Version and match it with the modem updates.

That link takes you to an individuals thread with a list of the updates that individual had consolidated. It doesn't mean that it's the most up-to-date, but it's at least a start based on your question. Maybe you might be able to find a more up-to-date one the member didn't know about.

Always do your research too....

Hello,

I am using the last few nightly builds on my i9505 and have one problem:

Sometimes, not exactly reproducable, by "playing" with the phone (e.g. browsing and changing some Options etc.) the whole Screen goes suddenly in color PINK for 2 seconds, then PINK and BLACK like a tic tac toe board and one second later the phone restarts automatically and after that, it starts normal and works normal.

but then again, by using the phone eg starting apps, changing Options etc. it happens again with that PINK screen.

could happen after 20 seconds on Optionscreen X, or after 10 minutes on app or Screen Y.

Severel times, I deleted Cache/Dalvic, and update the Google Play Services - but no luck. And complete wipe doesent change the problem.
[Galaxy S 4 i9505 Android Development] grantd:
I experienced this on CM13 on my SCH-i545 at random times when playing Pokemon Go. Pretty sure this is a system crash, similar to a BSOD on Windows. It only happened a few times so I couldn't narrow it down to a particular set of steps.

Can you reproduce it consistently? Giving the exact steps and seeing if others can have the same issue might help to find the root cause and get a fix.
