Wifi not turning on - Galaxy Grand Prime Q&A, Help & Troubleshooting

So I had AOSP Extended and I just flashed this stock rom for my baseband - G530HXXU2BPB2.
An d after flashing everything went fine except wifi it won't turn on. Like if I turn it on the circle on the bar will be on right for 2 secs then go back to off. Could it be because the Firmware I downloaded is Russia when I am not even from russia ? haha. Anyway to fix this ? because I don't have any wifi at home and only use data so I can't really keep on downloading big files. Is there anyway to fix this without downloading another firmware?
Thanks

your modem.bin is bugged, you need to reflash moden.bin of lasted fw working wifi in your device

[Q] i9505 LTE modem flash issue

Hi all,
I've had my phone locked on Tele2 (CRO) network which I needed to unlock to be able to use T-mobile SIM. I've used Odin 3.04 and followed the instructions to update modem to I9505XXUFNB9. I've managed to unlock the network this way and use my new SIM but the connection (both phone and mobile data) kept switching on and off constantly.
After that I've tried another firmware, namely I9505XXUFNDG for T-mobile but the problem now is that mobile is almost always off with no possiblity to connect and WiFi is blocked completely (security notification "Your device's security has blocked an action").
Basebands registered properly after every flash.
Phone is not rooted and me not being a power user would just love it to work as it was intended to
Followed the guide, all firmwares downloaded from here
Appreciate any help.
Might be onto something. After reading through this post seems I need to apply WiFi fix but I cannot tell which one to use for my phone (I9505XXUFNDG) as it's not posted. Kernel version 3.4.0-481100.
I've tried I9505_WiFi_FIX_MDM.tar and I9505_WiFi_FIX_MDF.tar but they just messed up the phone completely.
Thx a lot.

Hi ,
you should flash the fix for the modem you have installed , try following:
Flash another modem from the list there
Now flash the modem wifi fix for that modem
If still in trouble re flash stock and start all over again.....

Thx, did just that and now it works properly.
Much obliged.
a problem started to show recently; when i select LTE/WCDMA/GSM for auto connect network mode when the mode switches due to signal availability it doesn't get reconnected. i.e. while under LTE it works fine but if i move and get out of reach it should automatically switch to slower network which it doesn't. this works fine if i select WCDMA/GSM then the switches are fine but LTE is not available under this.
one more thing i noticed since i'+ve flashed the phone is that the upper part of the phone gets very very hot (a lot more than before). since the flash i've also had to replace a microSD card which died within weeks (not necessarily connected but worth noting).
any suggestions welcome.

[Q] Bluetooth Bricked/Dead ?

Hi,
So my father had his S4 (9505) about 4 months. But as of today the bluetooth wont turn on. The cool thing is WIFI works (!) as normal.
I tried :
install custom recovery and wipe everything
flash newest rom (even with PIT-file)
flash new modem and nonhlos.bin
opened the device to clean antenna
nothing help....only wifi and normal network 3g/4g still work as normal....
I knew there was once a fix to disable/enable LTE in /data/property/..... maybe there is the same for bluetooth?
is it possible to log this error anyhow ? if yes please tell me how /what program....

[Q] Mobile network disconnects when the screen is off

Hello,
I've noticed something strange this past month. I was getting data disconnections and I could'nt figure out why. Each time I look at my phone, turning the screen on, mobile network (voice + data) is missing for a few seconds, and comes back.
Now I know that if I keep the screen on for a while (I tried more thant 1 hour), I don't loose the network, but if let the screen go to sleep I immediately loose the network (I don't receive whatsapp messages in background), and when I turn the screen on, it comes back.
Weirdly, when my phone could reach 4G, I had (almost) no disconnection. It only happens in a 3G, edge, or nodata zone.
I changed my carrier (I just moved from europe to New Zealand), and it doen't change the problem.
I'm using CM11-Nightly (sept) on a I9505. I tried installing an old nightly(from july), and it was really full of error messages, so I switched back to a recent nightly, but in the meantime I had no disconnection.
Thank you for your help

I don't know exactly where this option is, but it's for battery saving. You can choose that somewhere in your settings I think
I think that's true for Wi-Fi, but I never found it for network.
And now it seems that network won't come back if I don't go to airplane mode and back to normal mode.
I'm having the same problem, seems to mostly affect lollipop installs.
Did you find a solution?

No I didn't. It seems that somewhere in july 2014, CM11 included a new version of the modem. So every CM11 build after that and every CM12 build is affected (I don't know about other roms).
I read that it was the way the modem handled finding the best network method. With the previous modem (v5 ?) it tried to get LTE, 3G, etc... but now it fails when it fails to get the prefered network.
4 solutions:
- flash the modem (didn't try it, don't know how)
- You're supposed to be able to choose you're prefered network in the options and choose 2G/edge. Didn't work for me but I'm interested in your feedback.
- get an old version of CM11
- live with it (my current option :'( )
There is maybe another solution, I'm not an expert, just a desperate user.
Hey again, I did fix it for myself.
The modem is the problem (I flashed my modem, and my bootloader just to be re-up-to-date).
If you want to get lollipop for yourself you should do it, its not too hard
Its listed as Qustion 14 on this here page: http://forum.xda-developers.com/showthread.php?t=2419762
I don't mind trying to give some pointers if you need help understanding how to do it, but I did this at 5am while sick so my memory of what I did is not 100%, never the less I would like to help if you need it.
Thank you for the advice (you came seeking for one, and ended up helping me ).
How did you choose which modem version to pick up ? the latest ? Do you have to do it after every CM upgrade ?
Edit:
I found the latest version from one of your links : http://forum.xda-developers.com/showthread.php?p=50965837#post50965837
Is the "Combined package - both modems in one flashable file." ok ?
And what does flashing the bootloader do ?
"What it does"... I am not 100%, I assume it initialize some part of the system, HW or kernel level, but I might be way off.
In any case I did use the dual modem pack to flash both "PHONE" and "PDA", another thread I asked in just replied to another user with the neccessity to flash the new bootloader aswell (dont know if the version numbers applies for you):
u must be using a 4.4.2 baseband and bootloader .. just a 4.4.2 baseband will not work .. once updated ur set

My question is on this page a bit down, and some replies a bit further down than that:

Tip: I had to save the PIT to a file (did it twice to be sure) with heimdall before using odin to flash (couldn't get heimdall to work for that part), all because odin would not play nice inbetween loading the PIT from device and flashing, this might not be a problem for you at all so it's just an FYI.
I managed to flash the modem & the bootloader. So far, no disconnection, so I'm quite happy.

[Q] S5 BNL7 WiFi Problem

Hello, today I updated my firmware from the polish stock bnl1 build to bnl7 build.
After solving some problems the ROM runs fine now. But it didn't restore my wifi passwords and if I restore the wpa_supplicant.conf from the bnl1 build, wifi won't even turn on. Thr bigger problem is, that it resets my wifi passwords every time I turn wifi off or restart the device. I hope you can help me....
My Device: SM-G900F, Stock ROM, Lollipop BNL7, rooted

Strange WIFI issue,please help.

Hello guys,im expiriencing strange issue with wifi in last couple of weeks.Im sorry if someone already posted thread with this issue,i couldnt find it anywhere on XDA.
Here is the problem:
i have sm n9005 and i was using stock 5.0 first,and then decided to try some custom roms.It was all good,and i changed couple of those.
At one point,i did firmware/bootloader update for some of the roms,i cant remember which one exactly,and phone started to act strange.
It could only see and connect known wifi networks (my home and work ones) and as much scanning i used,it simply can not see/scan other
networks in the area.Its really annoying.When i do factory reset/data on any rom,its all good for some time,sometimes like few hours,sometimes
few days,but it all gets f_____ up again,and i can only use networks i already used in the beggining.I tried few times to flash stock rom via Odin,
it was all good,but after some time (as i said,sometimes less sometimes more time) its acting strange again.Maybe im flashing wrong stock rom
in Odin,i cant really tell whats going on.Current baseband version is n9005xxugpof3,if anyone knows how to solve this,please help,i will provide
any data needed in order to solve this annoying problem.Thank you in advance and God bless you!
p.s.
here is the version of stock rom i flashed,its N9005XXUGBOA5_N9005XEOGBOA4_N9005XXUGBOA1_HOME.tar and i think its Poland version
or something like that.
update:
tried to flash original italian ITV stock rom,all worked fine for a day or so,and it all went back wrong again :/
Phone is not showing any WIFI network,but when i add it manualy,which i tried with my home network,
it works well.Also,its sending me notification when available networks are on,but when i enter wifi
section,list is empty again : / Mac adress in my wifi options is ok,and IP adress is unknown.
Any ideas,guys,i would really appreciate any sort of help?Thanks!
