[Q] How to fix I9505; no sound, no mic, phone app not responding

Summary: my I9505 mic, earpiece and speaker don't seem to work and cause fc/not responding on functions that use them (phone), what should I do to resolve? (I have flashed a bunch of ROMs, and a couple modems...).
Detail:
Ok, so firstly I must apologise for not recalling the somewhat random sequence of events which has brought me to this juncture... I was fiddling around with a few different ROMs and when I noticed the problem I sort of frantically tried flashing things to fix it (yes, I'm aware this is a very sensible approach )
I've flashed a few different ROMs and at some point flashed a new modem.
I noticed yesterday that I was not getting any sounds out of my phone, noticed when using the volume buttons, no beep; further investigation revealed the speaker, earpiece and microphone seem to have decided to take an indefinite nap...
Any suggestions on how to proceed with waking them up?!
There is a message in the logcat:
getDeviceForStrategy() speaker device not found
Though not sure if this helps at all.
Making/receiving phonecalls the screen goes black and either rings out to voicemail before I can answer, then displays not responding wait/close error or the other person answers and neither side can hear then same not responding error.
I've not changed the bootloader (as far as I'm aware...).
Wifi/mobile internet work fine.
Tried flashing an old modem, factory resetting, reflashing a ROM (currently CM10.2) but no dice... since I'm a bit lost I figured stop fiddling and ask for help
Current baseband: I9505ZHUAME3
Current bootloader: I9505ZHUBMF4
Any suggestions on how to proceed to un-screw my phone would be greatly appreciated. :good:

Thanks for the reply; downloaded, flashed as CP seemed successful but still no joy, same no sound and unresponsive phone app
It says WiFi fix; WiFi is working, how would this fix the audio problem? (not being snarky, just curious as to the relation to the problem)

Flashing a wrong LTE/Wifi fix will loose your sound . in Old bootloader you can't flash any newer LTE modem than UBMH1.and for the New bootloader you can flash all the new LTE modems, including MKF etc.. So boot your phone into download mode and check if you have an entry of knox warranty void then you have newbootloader. and make sure you manually turn off your phone and wait atleast 10 sec and boot your phone into download mode and flash . (Because sometimes flashing a modem/lte doesnt work and need to do it twice.
Use Odin
Untick Autoreboot
Flash modem
Reboot once again into Download Mode using (Power+Voldown)
Flash Modem once more
Once done,unplug then reboot device manually.
If this doesn't work, try repeating the flash process again while rebooting manually and with auto-reboot option turned off.

Thas good your still in Oldbootloader try this one If the problem still persist , since your still in oldbootloader flash a 4.2.2 Stock rom , check it from here and download the one that base from your country. Remember 4.2.2 ! not 4.4.2 . instead writing thanks please hit that thanks button >

Im still in oldbootloader and i just download and flash a custom rom 4.4.2 via recovery .. and incase something wrong with my phone in a future . iE Hardware related.etc theni can just flash a 4.2.2 and send it for repair for free... and about newbootloader , flashing any custom rom/rooting will triggered your knox , so feel free to flash the latest stock 4.4.2 kitkat if you dont care about your Warranty. But like i said you can still flash a 4.4.2 custom rom without flashing a newbootloader (Never flash a newbootloader , Make sure to ask first before flashing anything) Have a nice day.
Edited: @mrlizard123 Never flash a latest Wifi fix so you wont get this problem again. only flash a GSM MODEM. if your flashing a custom 4.4.2 rom then you need to flash a latest GSM MODEM base from your country. in order to fix dropping signal issue when the phone went to sleep.

Those files are the extraction of the kies .zip download. They are flashable trough ODIN 3.09. New devices like note 3 firmware are also donloaded like that,,,,
here is a sample of how you should use those files...

QUESTIONS.
Hi.
So all those 4 files listed are used at once?...
How do you get them into Odin3?.. Do you link from this page or do you need to download them AND how do you do that?
Would it fix the blue screen of death?
I have tried the AT&T OTA lollipop that just came out and the pad won't update?..
Is it an AT&T update or is it a Samsung update..
Do I need the AT&T sim card installed for it to update as I'm using a different carrier for the LTE?
Updated back to stock ROM and still no OTA update.
Richard.

Locate the lollipop update try downloading it to your sd card and reboot in recovery. Tell it to update from the file on the sd card. This way works! I know because I have done it . The AT&T update doesn't work, now matter how many times I try it. I remember getting the file from Samsung updates. I hope this helps, couldn't find my source when I went looking . Best of luck to you...May your update go smoothly. :laugh:

So just put that complete file on an mini SD card and it will find all the files it needs and update itself?
Does the new lollipop update remove the infamous AT&T blue screen of death problem?

If you downgrade to android 6 you need to factory reset which you obviously cannot do because you have an MDM lock.
Why does this tablet have MDM software installed is the question?
Also I can't see how you have managed to get FRP locked when you have MDM as this prevents factory reset unless you have installed a custom recovery or something?
In that case all that is required is to flash the stock firmware.

So this means someone has somehow managed to factory reset via recovery triggering the FRP lock.
How considering it is already mdm locked is a mystery?
There are ways to get by FRP using accessibility mode, but the firmware would need to be downgraded to the earliest possible.

The problem is if you try to downgrade the os version you need to wipe the data partition.
You cannot do that because of mdm.
What's the full firmware build number?

OK just re-read your post, you already have the correct firmware.
When flashing the firmware flash CSC instead of HOME_CSC.
This should wipe your DATA partition and remove the MDM software.
Check repartition in ODIN when flashing. It should find the PIT file in the CSC file.

(Problem) SW REV. CHECK FAIL. DEVICE: 2. Binary: 1.

Hello guys!
I have a big problem with my S7 edge (G935F)... The problem begins when I forget to turn off the OEM security and then I did an update to my Magisk root... When I tried to reboot my phone it doesn't pass of the first logo image, meaning that I broke the "security", so I read about that and then I flashed a firmware, an official UK (BTU I guess) firmware and then I flashed TWRP via Odin to restore a nandroid that I did when I bought my phone... It restored the EFS partition/folder and when my phone reboots I had no network signal, no IMEI... I just tried everything (I hope not) and I can't give back my IMEI and my network signal... When I try to patch the certificate to recover my IMEI via Odin in the download mode it says: SW REV. CHECK FAIL. DEVICE:2. Binary:1
I don't know if I explained it because my english is too bad, but I tried, I know that someone else have the same problem than I because I saw it. Do you find the solution? I'm out of my country and I need it so much :crying:
Regards!

I did it with three diferent stock firmwares and the problem persists (no network signal) I think that is something with the EFS folder, I restored a backup of it but is the same, I have not signal yet, but thank you!

Hey brother it happened with me too, unfortunately, I had to format my internal storage to fix this, you need to flash the latest nougat firmware via odin with csc including bl and modem and then start in recovery then format and start phone, remember you would need to put the google account which was previously there in the phone to unlock and complete setup process (very important here)

Download the latest firmware from https://updato.com (it's fast and reliable) then start in download mode, run odin with administrative privileges, select BL AP Modem and CSC (dont use home since we wish to clean fornat), and in odin uncheck auto reboot option, after the ODIN shows 'pass', disconnect the cord from pc, now you have to be very quick here since our battery is not removable, in order to shut down s7 edge from odin mode, all you have to do is press, volume down, volume up, home and power and as soon as it goes off connect the cord, the battery will show up and now it will be in charging state, after that disconnect the cord, (the phone is now clean fornatted and in off stage) and now boot into recovery to wipe data and cache using default recovery, then reboot phone and then log into your existing google account.
I know its tricky and maybe there's an ez way around it but this worked for me so I'm sharing

SOLUTION, thank you all for your answers!

I tried it at first instance but I could not because my Bootloader was updated to the "U2" version, what I did after that was search the Combination file updated to the U2 bootloader, after a long search I found it.
In resume, The solution is what the OP of that thread says but if you have the same problem like me with the Updated bootloader you need this file instead of the files that are shown there:

Hello guys!
I have a big problem with my S7 edge (G935F)... The problem begins when I forget to turn off the OEM security and then I did an update to my Magisk root... When I tried to reboot my phone it doesn't pass of the first logo image, meaning that I broke the "security", so I read about that and then I flashed a firmware, an official UK (BTU I guess) firmware and then I flashed TWRP via Odin to restore a nandroid that I did when I bought my phone... It restored the EFS partition/folder and when my phone reboots I had no network signal, no IMEI... I just tried everything (I hope not) and I can't give back my IMEI and my network signal... When I try to patch the certificate to recover my IMEI via Odin in the download mode it says: SW REV. CHECK FAIL. DEVICE:2. Binary:1
I don't know if I explained it because my English is too bad, but I tried, I know that someone else has the same problem than I because I saw it. Do you find the solution? I'm out of my country and I need it so much :crying:
Regards!

first of all, i need your firmware, your root method you tried. If you bootloop your phone you must flash the stock firmware through odin .. and then root with a legit way.

i am little bit confused, help me to help you ! Well , now your phone is bootlooped or no? If it is not , what rom do you have? stock one ?
You can try this method as well, because the method you tried needs to flash a custom rom . i do not like that kind of root method . For me first you flash twrp through odin, flash root, better magisk, and then flash your rom .

alright you are gonna need to flash stock rom from sammobile look the link bellow, but first create an account on sammobile . the process will take like 3 hours . after that you flash the stock rom, and boot your phone normally, enable dev option by tapping 7 times on build number on software information, then go to developer options and enable Usb debugging, get your phone on download mode by turning off your phone and pressing the power button, bixby button, and volume up to flash root . i think you know the process . i will be waiting for you reply.
search for your country and csc first. unless if you already have the firmware on you pc.
