Yeah thank you :)

I am just fresher in rom development and also I don't have high end machine to compile ROM. If anybody interested in building lineage ROMs with volte and some extra features. I am glad to share my yureka resources and guides regarding signing and release builds.

i am facing network problem, if data connection changed from sim 1 to sim2 or sim2 to sim1, My mobile is out of the network & network not coming after restart the mobile , pls. help
[YU Yureka Android Development] rajesh@xda:
Lineage has dropped official support for yureka due to multiple errors and lack of developers. This unofficial build is completely based on recent lineage source code. Nothing from my part except the compilation. Bugs are common in unofficial builds. I am not sure about it dude.:good:

This build is to emphasize that Oreo and pie ROM can be built in enforcing mode without compromising device security. As far as I know ROM build in permissive mode does not support enforcing mode ( not able to use payment apps etc). Most of the oreo and pie ROMs for yureka are in permissive mode. If it is build in enforcing it support permissive mode. Any talented developer can come forward to build ROM for yureka and fix some serious bugs without compromising its security and features.:good: It will be nice if such thing happens:)

Dear Sir,

after flash NON-HLOS.bin my yureka ao5510 not coming in TWRP Recovery. only YU LOGO COMING ,pls. help me
[YU Yureka Android Development] rajesh@xda:
Flash recent twrp through fastboot. This may help. If no os or recovery present phone stuck in yu logo.
[YU Yureka Android Development] sonuchauhan65:
Sir,

i am flash TWRP 3.2.3.0 many times through Fastboot mode, but problem is the same.
[YU Yureka Android Development] rajesh@xda:
Are you able to boot in recovery mode. How this happened.? Did you reboot the phone without os..?

Flashing stock rom again will help.! Try to flash rom in fastboot.:confused:

Dead battery also can cause this issue.!

Don't know exactly.

Is your boot Yu logo shows any message like "# userdata" or "# recovery". If so you have corrupted the userdata or recovery partition. You need to flash those partition on fastboot mode. Try 2.5gb partition tool to restore your phone. On fastboot follow the commands

" fastboot erase userdata" to erase userdata. proceed this command with caution bcos it will erase internal memory also. ". Take back up.

" fastboot erase system" to erase system partition. Then flash stock rom 12.1 followed by your favourite custom rom:good:
[YU Yureka Android Development] sonuchauhan65:
''#recovery'' with Yu logo Shows massage' but now i am write the command ''fastboot erase userdata'' massage coming wating for device

or using 2.5 gb partition tool massage coming ''fastboot.exe has stopped working, pls.help
[YU Yureka Android Development] rajesh@xda:
U need to check whether your phone is detected in fastboot by command " fastboot devices" and proceed with the tool. #recovery message indicates your recovery is corrupted .Better connect your device only in fastboot mode and wait for the tool to respond (it will take to time to respond donot close the command window). For restore use the same tool you have used to repartition ( Annabathina tool or ag tool) .Annabathina tool is good at restoring to original partition and recent ag tool is good to repartition to 2.5gb.
[YU Yureka Android Development] sonuchauhan65:
Thanks sir for your support now my device partition restore successfully and working fine , thanks again:good:
[YU Yureka Android Development] sonuchauhan65:
Sir,

Now i am facing ''HOTSPOT PROBLEM'', My device notification saying that hotspot is active but not showing in other device, pls. provide any solution
[YU Yureka Android Development] rajesh@xda:
You have to properly configure network name and password in portable wifi hotspot settings. Wifi hotspot is to share your network data to other device. Turn your network data before turning wifi hotspot. This may help:good:
[YU Yureka Android Development] sonuchauhan65:
Sir,

I am already configure properly the network name ( Yureka Android) and password in portable wifi hotspot settings & data connection always on but my device network name show only 1~2 minutes in other devices
[YU Yureka Android Development] rajesh@xda:
Have you set any portable wifi hotspot time out:confused:. If so, choose never from option menu and try. If this problem persist may be it is source code error. I am not sure about it. lineage has to deal with it:good:
[YU Yureka Android Development] sonuchauhan65:
I am not set any hotspot time out , hotspot toggle always on in the device but not connect or show in other devices
[YU Yureka Android Development] rajesh@xda:
Ok let me check this issue on my phone soon and respond to you as early as possible.:good:
[YU Yureka Android Development] rajesh@xda:
Tested the wifi hotspot. It is working fine on my yureka plus. I connected both on laptop and other devices . No such reconnecting issue. I have tested on Airtel network. Turn off wifi scanning option on your client device to avoid frequent disconnection and also make sure strength of your phone wifi signal :good:
[YU Yureka Android Development] sonuchauhan65:
Thanks Sir for your support:good:

Is widewine L3 supported in this ROM?
[YU Yureka Android Development] rajesh@xda:
No idea.:confused:
[YU Yureka Android Development] ptg251294:
can you check it with DRM info app from play store, please?
[YU Yureka Android Development] rajesh@xda:
Check it out:good:
[YU Yureka Android Development] ptg251294:
Thanks. Now I am waiting for someone to find a way to enable VoLTE in this ROM. Once VoLTE is enabled, it will be best ROM according to me for Yu Yureka.
[YU Yureka Android Development] rajesh@xda:
Testing on volte compatible source. Will release ota if possible with some fixes as much i can.

Need assistance for adding volte and some features to this rom or any talented developer can come forward to takeover this lineage project again :good:

Feedback is welcome:)
[YU Yureka Android Development] ptg251294:
I want to help but I don't know anything about ROM development. Where to learn about ROM development?
[YU Yureka Android Development] rajesh@xda:
For yureka you can get basic building stuff from here https://wiki.lineageos.org/build_guides.html. Official lineage support for yureka ended on nougat. No errors are found on compilation of nougat rom.

For advanced thing you have to learn some basics regarding device sources ( device tree, kernel etc) so that you can rectify some errors while building ROMs. (oreo, pie and so on )

In terms of hardware resource you may need a quad core cpu with maximum of 8 or 16gb RAM.

Not able to install gapps shows insufficient space

I have used the extender script. Still no help

Can u just say what can I do to install gapps
[YU Yureka Android Development] rajesh@xda:
Delete inbuilt webview in system. And install pico gapps. Download chrome or webview from apkmirror and save it in your sd card. Skip setup at initial start up. install webiew or chrome from sdcard and add your google account in settings later:good:
[YU Yureka Android Development] prabhav2816:
So first I flash ROM without gapps

Then delete webview (so need to flash magisk over here for it)

Then install gapps after that..!?
[YU Yureka Android Development] rajesh@xda:
Magisk not needed. All apps works without magisk.

Install gapps after free up space from system..u may need to delete inbuilt music app..email app..webview to create atleast 200mb free space to flash pico gapps.
[YU Yureka Android Development] Abhishek_DK:
How can I go about deleting those apps?
[YU Yureka Android Development] rajesh@xda:
use twrp file manager:good:

clean flash or dirty over "lineage-15.1-20181202-UNOFFICIAL-tomato-signed"?
[YU Yureka Android Development] rajesh@xda:
Ya dirty flash allowed. Report back if it fails:good:
[YU Yureka Android Development] Saif Suse:
Finished installing the previous build and saw update flare. Downloading new build will post back results.:good:
[YU Yureka Android Development] Saif Suse:
Dirty flashed with wipe dalvik/cache, no error during flash process. bootloop.

Clean flashed, no error during flash process. no bootloop.

System Partition Size was showing 1.2 GB, but after some tries of resize partition and repair partition option on TWRP, it was showing 2.5GB again (same bug triggered after flashing previous build).

using f2fs for cache & data, please add support for system aswell if possible, I will report back if i encounter any bug.
[YU Yureka Android Development] rajesh@xda:
Build is in default partition so that it can support extended partition but not other way around:good:
[YU Yureka Android Development] Saif Suse:
alright, this and previous build is really snappy, thanks for that.

latest build's trebuchet dont support dark mode or bugged? app drawer in previous build was getting dark background by enabling system wide dark mode from settings.

should i flash volte modem or will it break functionality or simply wont work?

any kernel you suggest flashing over this rom for some extra unicorns?

any plans for LAOS 16?
[YU Yureka Android Development] prabhav2816:
Well the proximity sensor is not working.Except that everything is cool .Hope can you fix this please .This rom is almost my daily driver ?
[YU Yureka Android Development] Saif Suse:
can confirm.

working fine in proximity calibration info, but proximity sensor functionality not working for calling or for accidental wake up.
[YU Yureka Android Development] rajesh@xda:
Change to dark wall paper .Trebuchet support some transparent style or switch to lawnchair or pixel launcher.

This build is wont support volte like default lineage .So dont flash volte modem. I am working on volte feature from some other source and will post it here if the build is successful.

Default kernel itself good. Other kernel not tested. Personally i wont prefer other kernels which support fast charging and some extra sound mods because it may damage your hardware. If you want extra features switch to permissive mode and gain root on this lineage kernel. This rom has some selinux denials (not tested completely). soon, I be will be adding permissive patch as add-on for this build . Make use of it:fingers-crossed:

LOS-15.1 Volte and LOS-16 build is in progress . I am planing for a stable and smooth ROM equivalent to stock experience.:good:
[YU Yureka Android Development] rajesh@xda:
As said it may be due to selinux denials . wait for permissive patch. Today i will be adding the link.
[YU Yureka Android Development] Saif Suse:
setting to permissive fixes backlit and proximity, what is this sorcery? xD
[YU Yureka Android Development] rajesh@xda:
SElinux denials. May be lineage developers left it half way:D
[YU Yureka Android Development] rajesh@xda:
Change to permissive mode. Permissive patch added for convenience:good:. Check post
[YU Yureka Android Development] Saif Suse:
APN and Data bug.

Device using mobile data even after keeping mobila data disabled.

Cannot use incorrect apn as a workarround because custom/edited apn is getting discarded automatically.
[YU Yureka Android Development] rajesh@xda:
Default lineage has some untested bugs. Wait for volte rom:good:
[YU Yureka Android Development] Saif Suse:
any eta for volte rom?
[YU Yureka Android Development] Rajendran Rasa:
Don't ask ETA,

Read XDA rules:angel:
[YU Yureka Android Development] prabhav2816:
Well because of permissive mode google tez not working.

Will magisk module can help resolve it!?

Edit :

Magisk solved the issue.

Hope volte ROM get soon so I can get rid of the jio4gvoice ?

Someone willing to give u something without u paying anything, u can't be greedy there.
[YU Yureka Android Development] rajesh@xda:
Volte ROM is under testing phase. Until now i gone through multiple sources from yureka developer community and working on sleepless nights for a smooth stable build. Three build came successful but i am not satisfied. Each source has some unique bugs:D. Moreover i have no volte sim to check the volte feature. I am ready to upload the builds.Is anybody interested to test VoLTE for me..?:good:
[YU Yureka Android Development] Saif Suse:
I'm interested.

Experimental Lineage-15.1 VoLTE signed build

https://androidfilehost.com/?fid=11410963190603895146

Note: VoLTE feature may or may not work.
[YU Yureka Android Development] jithindev:
rom is good. But iam facing some issues

1. Play store not working after 8 Jan build. I tried clearing data and I also tried removing and adding google account.

2.when i browsed using default browser google said something like "there is unusual traffic in your system" and verified whether iam a robot.

3.Facebook app is very laggy when scrolling.

4.Proximity sensor was not working.but after flashing permissive patch its now working fine.

5.wifi has an issue....just after flashing rom wifi was working fine and also hotspot...but after some use it is not working properly...wifi is not turning on even at settings...after that hotspot is also not working...reboot won't solve this...I also done factory reset still not working...atlast I flashed lineage os 14.1 now wifi is working fine.

6.battery backup is not very good.

rom is goood please try to fix these issues...
[YU Yureka Android Development] rajesh@xda:
I have been using this ROM. This is my daily driver. ROM is working fine and smooth.

Have you Clean flashed the ROM.?

Are you using volte build.?

Are you using default partition.?
[YU Yureka Android Development] jithindev:
ROM is smooth except that issue with Facebook app...

yes I have clean flashed the rom...

Iam not using volte build...I flashed the build named

" lineage-15.1-20190125-tomato-signed.zip ". my modem is also nonvolte...

iam using 2.5 gb partition...
[YU Yureka Android Development] rajesh@xda:
I am not using fb .

Volte and non volte build uses different source. If interested check with volte build. It may help. Volte build support normal non-volte modem:good:
[YU Yureka Android Development] jithindev:
OK bro...I will try it...
[YU Yureka Android Development] Saif Suse:
I'm using same build, I have none of those issue you listed

and i can confidently say that battery backup is much better than stock rom.
[YU Yureka Android Development] rajesh@xda:
Bro, have you tested the VoLTE build. Is it working.?
[YU Yureka Android Development] Saif Suse:
sorry, i was busy with something, i'm flashing the rom now, will let you know if I find any bug.
[YU Yureka Android Development] rajesh@xda:
If not working better go back to non-VoLTE modem again. It will work in this build. Volte build follows different source. Check the smoothness of the ROM and report back. It will be helpful for the further development:good:
[YU Yureka Android Development] Saif Suse:
flashed the rom, volte modem causing "com.android.phone has stopped working" (just like any other non-volte rom)

tested it without volte modem, rom is just as snappy as the non-volte rom. camera and other elements feels the same nothing noticiable so far.
[YU Yureka Android Development] rajesh@xda:
Will try to solve this issue on next stable release:good:
[YU Yureka Android Development] jithindev:
I was not using stock ROM...I was using some other unofficial lineage os 14.1...and felt like battery backup was better in that...let me try volte build...
[YU Yureka Android Development] Saif Suse:
try to flash stock CMOS 12.1 Rom via fastboot then come to this rom?

volte build is just an initial build, released on request, imo wait for stable release.
[YU Yureka Android Development] Saif Suse:
so last night i was flashing multiple roms and decided to flash build older build "lineage-15.1-20181202-UNOFFICIAL-tomato-signed", and i think its more fuild than "lineage-15.1-20190125-tomato-signed".

did you notice that?
[YU Yureka Android Development] jithindev:
;)

I flashed stock cos 12.1 and then increased partition

then only I flashed this ROM...

I think december build is better because only wifi issue was there in it and Facebook app lags a little

---------- Post added at 12:16 AM ---------- Previous post was at 12:02 AM ----------

I tried volte build...i flashed both ROM and gapps...but didn't flashed permissive patch file...

It is very laggy...it took much more time than normal to boot initially...also during initial setup phone got hanged and rebooted...after reboot I completed the setup... UI is laggy...

playstore is working fine

proximity sensor is working fine

wifi is also working fine(i used the ROM only for little time)

But when I rebooted phone got stuck in bootloop(lineage os boot animation is showing but os will not start even after waiting for long time)...

I was not able to check volte because I don't have volte sim card...
[YU Yureka Android Development] rajesh@xda:
Initial startup time depends upon type of Gapps package used. I have used gapps full package so it took me around 6 to 7 min to boot.

Normally on a fresh install, ROM will take time to update playstore libraries and google account etc. It may look laggy on initial start but give time for the ROM to settle.

Latest build added some features from YU developer community like button backlight, YU doze, Display lights and source code changed moderately from lineage source. :good:
[YU Yureka Android Development] prabhav2816:
Well installed with both stock and pico gapps but Sim doesn't get detected and com.android.phone stopped error constantly be coming

Any solution to it!?
[YU Yureka Android Development] rajesh@xda:

[YU Yureka Android Development] bickynath690:
Any volte update...with no bug
[YU Yureka Android Development] rajesh@xda:
As far as i know aospExtended-4.6-official (Nougat ROM) will meet all your needs. This ROM was build by Ritesh Saxena (official maintainer). I have patched that ROM with latest kernel so that it meets all security concerns .

1. Enforcing SeLinux

2. Release keys

2. Feature rich

3. VoLTE support on enforcing mode.

If interested in flashing the ROM. reply back. will provide you the patch and kernel.:good:

I have an idea that Lineage oreo ROM can be build on the same device tree of Ritesh saxena . It may support VoLTE on enforcing mode and may be bug free but i have no time and resource for building and testing the ROM.
[YU Yureka Android Development] bickynath690:
Recently update lineage os ROM....is no sim detect and 1st boot not completed.... So
[YU Yureka Android Development] rajesh@xda:
Recent ROM hasn't fixed long baseband issue at source level..so volte wont work. I have added the volte fix and instruction for the build in my github page. If anyone interested in building lineage ROM with volte can make use of it.:good:

Right now I have no pc or laptop to build and test the ROM.
