Wifi Problem

Hi Devs,

I install the rom previous weekend and must say I am impressed !!

Good work guys.

I haven't test the bluetooth but I have an issue with the wifi.

Connecting to my box at home went fine but when at work I can't join the network.

There are new options : Certificate CA and Anonymous and I don't know how to fill them.

Any idea ?

A little improvement : when listening to music and pull the earrings out the music switch automatically to the loudspeaker, on the stock rom it was disabling the sound. I found this more useful.

Cheers.

If you got the kernel source you can start merging my s3plus changes into your kernel
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] fire855:
Torch will be fixed in the next build.

Next build also has some bluetooth changes. Maybe it fixes problems.

USB connection to PC

Hi all,

When connecting the phone to a PC running windows 7 / 64, the pc tries to install some drivers and fails.

The phone is never recognized by windows.

It's a minor thing, I got other options to transfer files but this could be useful as a daily use.

Cheers

It's a bug of windows. Try re installing mtp drivers.

Thank you for a fantastic feature-packed and smooth rom!

In my S3+ the management of the sim cards is still a bit messy... I don't know if I'm the only one or not.

Often references to SIM 1 or SIM 2 are not correct (like what is supposed to be SIM 1 is referred to as SIM2 or viceversa).

Is anyone else experiencing this, as well as some weird behaviour with the sim cards now and again (disconnections from the network and LTE signal, despite the coverage being very good here, reverting to 3G) ?

Thanks, I look forward to the next update.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] gillou78:
Hallo der Teufel,

Very good idea you had, I uninstalled manually the MTP driver then connect the phone and windows recognized it immediaty.

Have a nice weekend.

Hi Fabio,

No problem with the 2 SIMs, I am living on the Franco/Swiss border and I have a SIM of each.

This works pretty well, you even have a new feature to add a specific ringtone for each SIM.

1 : in the More section / Mobile Networks / Acces Point Name : do you have the right APN for each ?

2 : in the More section / Mobile Networks / Preferred Network type : do you have LTE enable for SIM1 and 2G for SIM2 ?

3 : in the More section / Network settings reset : you can reset both SIM and reconfigure

Hope that it helps.

Cheers
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] Blackcrown:
No, you are not alone. For me, the phone is not usable with 2 Sim cards. I already posted logcats in this thread.

I don't know if the devs take this serious and investigate since it seems to hit only a few users.

I am in Germany and a Vodafone SIM causes the problems in Slot 2.

[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] fabioganga:
I'm happy to also send my logcats, do you have any link showing how I can do that and attach mine?

In my case, SIM 1 is Yoigo Spain (214-04) LTE sim and SIM2 is Wind Italy (222-88) non-LTE enabled SIM.

Thanks!
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] DerTeufel1980:
As you may know, fire855 and me are in Germany as well... 'unfortunately', we never could reproduce this bug.... And from all s3 plus users, I only know you two... Hence, a wrong setting (apn) sounds more logical to me.

You also could try a different second card though
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] fabioganga:
Thank you for your interest in my issue DerTeufel1980, that's very kind of you.

I'll try using a different card for a couple of days in SIM2 and see. if it fixes it. I'll let you know, thanks.

Hello.

The torch doen't work fine yet. From the status bar, when you switch it on, the led activates just for a moment. Like when you take a picture.

I have seen that the bluetooth menu in the status bar has change. You can not connect to devices from there. Sincerily, I liked better the previous one. Also, triying to connect to VRBOX bluetooth app crashed and I continue without being able to connect with VRBOX.

Thank you. Regards.

Update to 7.1.6

Hi guys,

A fast feedback from 7.1.6 install.

I did a dalvik, cache, system wipe before installing, install and reboot.

Gapps are gone, some apps are still working but the play store is gone.

So I had to flash gapps back.

Did a wipe again and reboot.

First reboot was unable to unlock the SIM but the second reboot is OK.

well after checking different apps, the torchlight is dead, no photo apps are working sorry guys but I revert to the previous version.

Just a pain in the a.... to reinstall gapps.

:p

After checking SuperSu and root are lost too !
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] miota85:
No, I didn't. I have been flashing all the releases without wiping data to not have to reinstall the apps in each release and it has been working OK until now. So, I didn't think that was because of that, sorry. I will wait until the next release and then I will do a clean flash.

Anyway, thanks for your answer.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] fire855:
It's because of that. The new build has very big changes.

It's not a flashlight bug. The whole cam seems broken for you. You are missing some changes

- The M.A.D. team -
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] miota85:
You have convinced me, for having the camera working is worth to wipe data. Please, could you let us know in the next releases if wiping data is necessary or not? You know, restoring everything you have installed and configured it is a bit annoying.

Thank you.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] DerTeufel1980:
Wipe data should not be needed next time.

[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] DerTeufel1980:
Not that I know. The band mode we added is working exactly the same way, as the one from mediatek engineer menu.

Only idea is flashing stock rom with flashtool and by using 'firmware upgrade' option. Then check if it is working, and if it is, flash back to this software

There's no guide, and no one of us has ever been porting roms
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] AlexZap:
I'm no expert on the hardware, but unless your phone/modem already supports these bands, even if they made it possible to tick the option, it wouldn't give you any more functionality. If the phone doesn't support it in hardware, a software switch won't make any difference.

Hello.

I have been experiencing some problems.

When I leave the phone in airplane mode during the night and in the morning I want to switch the airplane mode off. I have to do swich the ariplane mode off (at this point don't ask for the pin) -> on -> off to be able to make it connect to the network. I have tried an instantaneus switch on -> off of the ariplane mode and works. So may be the problem comes from being with the airplane mode on some hours.

Another thing is that yesterday I wasn't able to receive calls, I do not know since when. I realized it when I received a mail from a person that tried to call me. It went back to normal rebooting it.

Thank you. Regards.

Hi everyone!

Thanks first of all to [MENTION=4761533]fire855[/MENTION] for this fantastic rom! Thumb up!

I would like to ask you what is the proper way to have root enabled on this rom. I am using SuperSu (I have tried with BOTH version 2.78 and 2.79) from recovery.

Although the device gets properly rooted on reboot, it would seem that the baseband is no longer working properly as it tells me that I have no sim cards... neither of my two sim cards is detected and, as such, it makes my phone being unusable :(

What am I doing wrong? Am I supposed to use a different version of SuperSU perhaps? If so, where do I find it?

As for the camera, the app works well for me. But as soon as I go into gallery, the phone becomes totally unresponsive for quite a while untile I click on stop the unresponsive Gallery app.

Thanks!

SIM1 disabled after night in flight mode

Hi all,

still on stable 7, which performs absolutely fantastic! The only "issue" I am facing is that, after a night in flight mode, the SIM card is not enabled again when leaving flight mode. Have to do that manually in settings. Not a big deal, just wondering if anyone else came across this.

I only have a SIM in slot 1, did not test the other one.

If required, I will collect some logcat next time.

---------- Post added at 01:41 PM ---------- Previous post was at 01:35 PM ----------

Hi fabioganga,

I had the same issue twice, directly after flashing stable 6 and 7. In both cases, the problem was only solved by doing a full wipe and re-flash. No changes in the procedure whatsoever, must have been some SW hickup...

Rooting on the other hand worked fine later on.
