I think the wifi settings in system\etc are not correct.
It happened to me.
Disconnect at every 5-10 min.
And i discover that on the LOS based rom i m not sure about AOSP because i m not using the notification are delayed.
Around 10 min after the message are send if the phone are in deep sleep around 10 min the notification delay a loot.
I found a fix but really dissapoint about custom rom development.
I don like the Miui stock rom but whit thats bugs .
So we need a pure stable aosp rom witch some config change and PA theme engine so i don need to download every week new build and start fixing the bugs after that.
I read in one plus forum the some users have the same problem but after flashing frimware the problem was solve.
So the next question is which frimware package we have to flash to fix the wifi dissconect.

I tried AndroidOne and wifi is stable. I would like to understand where to intervene to solve the problem with other lineage constructions 14.1 and 15. Maybe I have to change the Kernel? do I need to intervene in the Build.prop file?

[Q] SK17i WIFI STILL NOT WORKING

Hello, I have a rooted xperia mini pro SK17i and I'm stuck to the CyanogenMod ROM 7.2.0 which seems to be the only one to work with my device.
I have written to you in the past to ask: "Why the wifi stops working if I try to install the cm-9.0.0, or 9.1.0-cm, or 10 cm-.........? ?? "
but no one has ever found a solution or the solution just did not work ...
I know from what I see in the forums that mine is a very common problem.
Now, years later, I ask again the same thing: "What should I do to install a more recent rom without losing the wifi?"
hello

wifi is defend by your kernel install.. try use another kernel like cm10 or cm11 and make full wipe n install your rom again.. or switch to another kernel and rom..
When I installed the cm-9.0.0 I used its kernel and I did the same with the 9.1 and the 10 ... did not work ..
But maybe I did not understand. You say, for example, if I install the 9.1 should I try Kernell of 10? Does it make sense?
Please........ :crying:
Does WiFi work on Stock ICS 0.587 firmware ?
I am ashamed but I do not know what it is ...
I'm no expert, I have not yet figured out a lot of things ... I'm still learning ...
I followed a guide to root my device and install the cyanogen rom.
If I look in the device info read:
Kernel: 2.6.32.9-FXP root @ ubuntu # 6
Android version: 2.3.7
This is all I know ...
Before roottare the phone I upgraded the original operating system of the phone and the wifi stopped working.
Precisely for this reason I decided to install the CyanogenMod ROM: to try to recover the wifi.
The cm 7.2.0 did it. The newer versions like 9, 9.1 did not work ....
My question is .... why??? it is obvious that it is not a hardware problem ...Because if it were so it would not work even with cm 7.2.0 ...
I'd like to update my device to the latest stable CyanogenMod rom for my device which is 9.1 ..
But I can not because the wifi stops working ... Heeeeelp!!

i think you ALLWAYS forget to flah the needed kernel. (& allways have this old GB kernel) so only wifi works with this.
you should make sure you following the install EXACTLY.
also cm 9.1 is old like hell. this is also no stable release. at least i wouldnt call it like that.
Look for LX (Legacy xperia) which provides cm10.1 , 10.1 (jb) & 11 (kitkat) this is far more stable. also many bugs fixed there.
cm 9(.1) is abdonned long time
First of all .. Thank you so much for your help.
Ok .. I'll try .. I'm just worried because in thr LegacyXperia site I see a lot of bugs in the Working / not working lists..

ok good luck this time all works incl. wifi (should work 100% if doing all right)
i think the best is to test a rom 1st so you can say how it fits your usage . just a few tips:
-use minimal gapps after flashing rom
-LX 10.1 has a release candidatefrom march this year its a pretty stable daily driver. dont use the 10.2 release theres nothing better..
-maybe also you can test cm11 if want, but keep in mind 19/3 is the last PMEM build which is based on old kernel, will probably deliver the stablest experience. IMO the latest release is also very good but this contains some bug like the ANDROID_OS wakeclock (need power on phone on charger to avoid this) & its still in development (so its more for dev users)
for the buglist:
CM10.1:
- maps flickering its true but fixed in CM11
- wifi gets drops sometimes .. but it work at all
- camera is not good quality/buggy bcuz of driver lacks (also no 720p video)
CM11:
- sometimes wifi a lil bit buggy but its minimal. works like a charm for me
- 720p video is working here
BOTH:
-sometimes bluetooth battery drain after using it (need reboot to fix) i not face this is issue when i send something to friend.... (works normal..)
- NO FM radio, HDMI port will not work (if you have one) & ANT+ (no drivers)
good luck for you
Yesterday I installed the CM11 and ... it works!!!!
The wifi works! :good:and I like the rom.:good::good: ... so ... thanks a lot bejunk!!!! thanks thanks a lot!!!!! You are a great!!

-power on . done
Thanks again! The only problems with this rom are:
- the phone takes a long time to boot. Almost two minutes ... every time ..
- When the device starts up many icons disappear and others are in different positions ... I do not know why ...
Is there a way to fix these problems? Maybe I did something wrong during the installation ...

There's a Q&A section for that ROM. Anyway, long boot time should be fixed in the upcoming release. The simplest way to fix disappearing icons problem is to install another launcher. Hope I've helped.

[Q] Wifi not showing anything

Hello .
I have and had this problem since cm11 for a long-long time . The wifi just doesn't show any AP when it should . Now I had this problem on cm 11 and the workaround was to switch wifi reign code to china ( or anything ) and instantly AP's would appear again .
Now I am using cm12 by Lysergic Acid and the problem is as far as I know there is no reign change in android lollipop . I was on beta 13 without problem . When beta 14 came I clean flashed it and there was no wifi even in first setup screen . Went back to my backup of beta 13 and wifi worked without problem . I have downloaded the build 04/23 and it is the same problem .
It is not hardware related because my old backups work perfectly . New flash of android 4.1 and cm11 also have no problem except maybe cm11 need wifi reign change once in a while . My info is as follows :
baseband version : i9100XXLPQ
If kernel is installed with a clean flash of cm12 by Lysergic Acid then I have not changed it .
I have been on cwm v6.0.5.1 for as long as I was on cm12 . Not sure what variant of unofficial build it is .
If it is a recovery problem can you point me to one compatible with cm12
I believe baseband is for 3G modem . If it has something to do with wifi plz correct me . I have no problem with my 3G.
I also don't see any 5GHZ wifi . I always assumed i9100 doesn't support it . But I think I am wrong .
Any help would be appreciated .
Sorry if this reply seems stupid, but did you try to turn off wifi, wait 5-10 secs and turn it on again?
I've had similar issues and waiting few seconds before turn it on again made the trick...
Hope it helps

Yes I have tried that . It doesn't work . As I said it happens even during startup wizard . No playing with the key solves the problem .
I have installed Ressurection Remix latest lollipop and It shows wifi correctly . Now that I think of it I installed some roms other than CM and I never had this problem . But I had this problem since cm11 in Cyanogenmod variants ... I'm gonna see if I like RR enough to keep .

Phone shutting down at 40%

Hi,
As the title stated, I have Redmi Note 3 SD with LineageOS installed. My phone suddenly dies at 40% when I put it on standby. Sometimes when I open camera app, it dies at 50%. I've tried many ROM including ViperOS, RR, but I haven't tried with MIUI yet mainly because I don't really like MIUI.
Have any of you guys get same experience as mine? What you guys do about it?
I'm planning to replace the battery because I thought it was the battery problem. But if you guys have any suggestions that would be great!
Thanks!
Update the IOS problem will be solved with new 11.2.1 version.
Just kidding
I would replace the Battery to fix issues like this if you the only one related to a specific Rom.
If you search trough the los thread you will see that some people had the same issue. I am not sure how they fixed it but i think some of the custom kernels had a patch to deal with this issue. I cant remember which one ( agni or radon) so you should search trough and/or ask those kernel developers.
This problem solved by changing kernel to francokernel. Thanks!

Hello ! Best xperia x custom rom ?

Hi everyone, i have been trying lately to improve my xperia x roms and tried a few of them but none seemed to work properly, sometimes random crashing or battery not charging ...
i was hoping you could help me chose a stable rom for everyday use and gaming (mostly emulation).
thank you in advance !!
I only tried "Unofficial LineageOS 16.0 for Xperia X" and "Unofficial AOSP9r46[X-X Dualsim-X Compact]". AOSP has less issues thanks to more modern kernel/drivers & you can use GCam, but of course it lacks all the comfortable things any LineageOS ROM comes with. The LineageOS has a black screen issue which occurs relatively seldom, but still regularly. It happens when you open an app, most often when switching fast between apps like when sharing a file with an app. You then have to kill that app which has gone black, but very seldom you need to reboot since the black screen is so that you even can't see the Android touchscreen buttons anymore to click back/previous app/homescreen.
I you install AOSP make sure to install the version you'll find deep in the thread and the updated boot.img. The folders on my harddrive are named "20200422 build with 4.9.219 kernel update" and "Updated boot.img with 4.9.230 kernel" which contain the files "AOSP-9-F5121-20200422-4.9.219brcmfmac.zip" and "20201003-aosp9-bootimage-4.9.230-f5121.zip" respectively and I noted down the following in a txt-file:
Edit : new boot.img with 4.9.230 kernel should be flashed instead of the one in full ROM archive, should fix some of the intempestive reboots (CPU frequency fix).
Only quickly tested on Kugo. Have the old boot.img at hand in case of problem.

TWRP I'm using is TWRP v3.3.1 for Xperia X (twrp-3.3.1-0-suzu.img).
Btw I never had charging issues, so make sure it's not a dirt/dust or hardware issue (worn out battery can also cause stability issues.
