the problem to that is actually only the modem of your phone. did your wifi and bluetooth worked earlier? when did you lost your wifi and bluetooth? did u lost your wifi and bluetooth after flashing another rom?

Solved "no sound" too by flashing latest stable official with new bootloader. Problem solved for me right after flashing. Flashing stable official fw with old bootloader didn't work.

Well you can try either do a factory reset / Wipe cache via recovery and if still doesnt work try to Flash/Download the firmware base from your country via odin , Or flash a different kernel.

[Q] Signal Problem with S5 G900F (i'm goin crazy)

Hi guys I have a problem with my S5 G900F. I can use it only in wifi mode. When i turn it off the network doesn't work. Also i can make call but after that i lose the signal and can't do anything. The only solution (that sometimes work) is to turn on/off the airplane mode to get back the signal or reboot the phone but the network doesn't work in any case.
I already tried about 4 different rom (and flashed also new bootloader and new modem) but nothing worked. Please help me because i'm goin crazy with this !!
Thanks a lot

Or when did this happen the first time?

big Wi-fi problem

Hello everyone.
I have a big wifi problem with my I9505.
I can't turn the wifi on, when I was on AICP the wifi setting screen was stuck with a message "Activating WiFi'
I don't think thait it is a hardware problem because time to time, after a reboot it randomly work until the next reboot.
I've tried to update to the next stock rom with a full wipe and it didn't solved the problem.
Thanks you all for your help and excuse me for my poor english.

1. Well, you have wrong firmware installed. You will have to flash via ODIN this ONE.
2. Try the WIFI now when finish the boot process.
3. Dial *#1234# when finish the flashing process and tell me what appears if you still without WIFI.

Lollipop doesn't work like android KitKat. Everyday people tell me exactly this and "Recent" no means that will work in your device. Downgrade isn't a problem atm coz you are on Lollipop and you want flash Lollipop too.
Thanks you for you help.
I have flashed the firmware you gave me.
Unfortunatly it didn't solved the problem but the wifi worked at the first boot and then after a reboot I can't switch it back on.
I really don't understant what's the problem with my phone.
[EDIT] I have attached screenshots from phone info.
Thanks a gain for your help.

It's hardware. You can try to clean the wifi/bluetooth chip in your device. Or you have to find someone who can replace the chip for you.

To clean?
If it's a hardware problem, how it is possible that sometimes it works?

Because if you are lucky, the antenna is dirty or the contact points are dirty.

How can I reset the flash counter? Triangle Away can't reset the counter on my phone. (5.0.1)
Do I need to downgrade to kitkat?
i have same issue here, i try custom roms, downgrade an other methods but issue persist, sometimes when reboot wifi turn on and connect, maybe not a hardware problem.

No flash counter on Android 4.4.2 and later, so no use for Triangle Away. The big concern now would be tripping the Knox security flag. As long as you haven't attempted to modify the firmware you'll be ok.

[I9505] Wi-fi issue with HOH2 baseband

Hello guys, I have flashed custom ROM based on HOH2 and I also have modem of same firmware, my wi-fi was working fine and it suddenly stopped working during use, Wi-Fi networks are detecting okay, but it doesn't connect with it at all, it does connect sometimes, and provides internet for sometimes, but after a while internet stops working, when I turn off and on again, it just doesn't connect with the wifi network. Is it known issue with HOH2 base & I will need to flash a modem fix or something? Or you are sensing hardware issue?
P.S I always used my phone with care, don't know what happened to the wifi while I was browsing, I hope it's not hardware fault and known issue with this base. Also this issue is on CM ROM as well as I checked, so only doubt is Hardware issue or baseband related?
Does anyone have the solution or I have to repair it?

Do a wipe data/factory reset from recovery.
Baseband doesn't affect wifi (Wifi relies on Kernel). Baseband is used by RIL. Have you tried Uzair40's suggestion ?
I downgraded completely to GN2 KitKat firmware through a tutorial and edited firmware posted here, and WiFi is working fine with it, i then upgraded to lollipop again and the problem reappeared (OH2 baseband/Kernel/Bootloader), so i switched back to GN2 again. Guess what, i think my device don't want me to upgrade anymore :/

Yes, i always do that when any such issue comes out, but it didn't fixed the WiFi..

what i would do now is :
- flash HOH2 without auto-reboot in ODIN
- reboot manualy in download mode
- flash HOH2 again with auto-reboot in ODIN
- let the rom completely boot
- reboot in recovery and do the factory reset
if you have the time, try this. If it dosen't work, try flashing another Kernel (Kushan, Hulk, or another TW compatible one..)
I have tried all of the mentioned kernels and most importantly
