[Samsung Galaxy Tab S8] Jake.S:
That is because your normal access is only admin not root. So it has almost full rights, but when you add root access it is mostlikely a modification that you have to do, either by a command or flashing a file. But updating the OS will revoke the root since method you used becomes unavailable for next update which is why it can reset your changes backwards so your root privileges becomes lost and your access is back to default as before. But I wouldn't touch bootloader since doing that also bricks KNOX so features for KNOX will become permanently disabled since it requires a working Knox chip to work, but since KNOX chip fuse becomes blown when bootloader is unlocked then feature like Samsung pass, samsung secret folder and such will no longer work.
[Samsung Galaxy Tab S8] SavXL:
Turns out you were absolutely correct. I downloaded and attempted to install the update, it booted into the stock recovery and got to 25% before erroring out. It booted back into Android and said that the update failed. Thankfully, nothing ended up getting removed or corrupted, and I still have root access. Guess I gotta stick to finding the latest firmware and patching it. ¯\_(ツ)_/¯

Will this ROM work for everyday use?
[XPERIA X1 General] LS21:
Hi, could anyone help with a couple of questions. I've recently got the X1 on O2 and I'm completly useless with WM!

1: If you can can replace the O2 panels with the standard ones (Sony Ericsson and Google), how do you do it? (I've seen the thread for the Voda replacements but wonderd whether it would be the same process).

2: On all the demos that I have seen the panels can be navigated horizontally by scrolling on the touchscreen but I can't seem to get it working!

I'm sorry if these are me just being stupid but I need help!

Thanks in advance for the advice!
[Samsung Galaxy S10+ Questions & Answers] musava_ribica:
Hello,

I have a samsung galaxy s10+ and I would like to downgrade android 11 to 10

I unlocked the bootloader but i cant get any stock ROM flashed that has binary version under 14 (E)

This is the closest I could get with Odin: https://samfw.com/firmware/SM-G975F/SIO/G975FXXSEFUJ2

Is there any way to bypass the binary lock?

This is the firmware I want: https://samfw.com/firmware/SM-G975F/SIO/G975FXXS9DTK9

Tried flashing it both from download mode and from bootloader, i get SW REV CHECK FAIL DEVICE 14 BINARY 9 error (or something like that I dont remember)

My phone is not network or carrier locked and any of that bs

I found an old thread where an user claimed to have successfully bypassed the lock but it is from 2017.. https://xdaforums.com/t/5-1-1-rom-sm-a310f-twrp-downgrade.3614602/page-2

Is it possible for me to downgrade my current device? Literally no stores in my area have galaxy s10+ on stock right now and probably won't , I bought this phone 1.5 years ago

Thanks everyone

I want to buy an S21 FE 8/256 phone, but I need call recording. I know my Note 9, Note 10+ had this call recording feature in "Phone", if I changed my CSC to India for example. Worked great, no complaints, its just what I need.

But can I do it on this phone as well? Like does Samsung still support call recording?

[Samsung Galaxy S21 FE] RF Junkey:
I am not sure where Samsung is on recording at this time. For non rooted devices there is a call record button on the stock phone app. If the button was missing a up date from the play store would restore and show the button. I don't know if Samsung has blocked this or not. However, this stock method of call recording will let the other party of the call know they are being recorded. Here is Google support page on this:

Few threads below, three about this topic. Sure it works, samkey and SEK csc. Snapdragon version meant for EU is without obvious countries like INS, SRL etx. Exynos version is APAC so plenty of choices of csc. Well version of FW, where samkey works ? Try out latest one, but IMO downgrade is still on option via odin.
[Samsung Galaxy S21 FE] lmbora2009:
So, despite what ING.KING says, it is not possible to put CSC SEK on snapdragon models. He tried with another model (maybe exynos) .. tried in person with both first and last firmware, IMPOSSIBLE CSC SEK.
[Samsung Galaxy S21 FE] Ing.King:
Try to downgrade FW with odin. I applied CSC change with Samkey at the end of February with: G990BXXS1BVB3 original CSC TMS and Snapdragon :).

Latest FW G990BXXU1CVC3 consist of OneUI 4.x upgrade, probably it is not supported by samkey yet.
[Samsung Galaxy S21 FE] lmbora2009:
Samkey replied that at the moment sek csc is not supprotato either with this or with any other previous firmware. After all, I had already done tests on the advice of ING. King but it was not possible to change it. On s22 changed in a moment... But not on s21fe. Can you send me a screenshot of your csc? So I turn it to samkey

[Samsung Galaxy S21 FE] Ing.King:
As I mentioned above, in my case CSC was changed from TMS Tmobile Slovakia to SEK.

Before SEK, I tried also SER(Russia) and CAU (Georgia) but none of them has CallRecording.
[Samsung Galaxy S21 FE] h8Aramex:
Oh man, this sucks big time.

So basically EU + Snapdragon -> don't buy phone.

Man, I wish I could find a solid phone on the market that won't set me back 9000$ and would work alright. I've looked at OnePlus, but their software has been a trainwreck since the new big update (Android 12 / ColorOS Frankenstein thing), and you get a mediocre phone. Sure, it works. But is it 1000$+ good? Hell no.

Xiaomi loves using their virtual proximity sensor that just WON'T EVER work OK.

Google doesn't really sell in EU (only select countries), and the phone I'd like to have (5a 5G) is Japan/US only.

ASUS comes with call recording, but they are still selling their older Zenfone phone for 1000$. Crazy.

Ehh, why is it so hard to buy a phone in 2022.

I just want root, or native call recording.

[Samsung Galaxy S21 FE] Fedepz:
Hi, I have the Exynos variant (Latam), and i have changed the CSC.

I buy my phone through my carrier, and it came with the bloatware apps... then i unlocked the bootloader and install the official ROM which i thought was the Free Carrier ROM. It was, but my CSC still was locked to the carrier.

Googling i came to a web page and then a video that explain how to change it.

IT WILL RESTART AND WIPE ALL THE DATA ONCE DONE.

First, copy or have handy your IMEI number, and know the code CSC country that allow Record Calling.

Then go to the Dialer and press *#272*(IMEI)# , a window will open, search, select and accept the CSC code that may work for you, and your phone will restart.

In my case the ARO CSC works, let me Record Calls and not forcing me to download carrier apps in the first inicial set up.

I hope that will work for many more.

I want to know this too, as well how to get the vibrate to be more noticable. lol
[XPERIA X1 General] Rudegar:
a device cant play louder then it was ment to do

so the only path would be to use a audio editor on a

computer to inc the vol on the file itself

of cause inc vol have a limit as inc higher then

the bit res would just result in overload and poor degration

of the sound
[XPERIA X1 General] fards:
There are several .csv files in /windows, these dictate the sound model used on the phone.

I've been playing with one, but can't get any boost that sounds okay, you can try changing the reg key from the operator assigned one (if europe then theres a 100db limit imposed I think) to the standard HTC one.

Have a look to HKLM\Drivers\BuiltIn\WaveDev\AcousticFile in the registry

mine comes as AudioPara3-XC-Vodafone_V5.csv

The standard HTC is AudioPara3.csv but theres also a AudioPara3-XC.csv in windows.

Try them out if you really want to, but don't blame me if it makes things worse, blows your speakers or causes pixies to come around and eat your brickwork!

you may have to hard_reset..
[XPERIA X1 General] THJahar:
I wonder if you're having the same problem that i'm having...

Whilst the phone lying open on a desk seems quite loud, the moment you put it into your pocket you keep missing calls as you don't hear it ring.

I couldn't figure it out until i accidently put my thumb over the bottom left side of the phone where the speaker hole is. if you do this it loses all of it's volume and becomes barely audible.

Now with my old K800 the sound kinda 'leaked' out. and was fine when in my pocket, but with the X1 it's becoming annoying that i keep missing phone calls
[XPERIA X1 General] Bxsteez:
I know for playing media if you use core player or tcpmp it will amplify ur volume but it will most likely get more distorted as u increase the amplification

[XPERIA X1 General] fards:
I've tried them, they mess up the sound, the csv aren't right for the x1, the internal speaker gets dominated by far too much reverb.

see my post above

I've tried all three csv files that came with my VF X1 and the VF one is the best sounding, so I'll try and tweak the gain levels some more to get a bit more volume out of it.
[XPERIA X1 General] fards:
OK all values in HEX.

Music playback through the speaker is virtually full strength in the VF csv, at FEC9 so there's no way that can go louder.

Audio during call using earpiece and through headset* is at 4000, changing it to 4800 gives very slight boost without distortion, anymore and I found I've turned the volume down during a call.

Same with music playback through headset * and standard system volume.

* I'm presuming headset is wired headset as it makes a difference when you try it!

vodafone csv attached.

If you dont have a VF X1 then you'll need to extract and rename this to what ever you registry points to at HKLM\Drivers\BuiltIn\WaveDev\AcousticFile in the registry

PLEASE BACK UP THE ORIGINAL FILE IN WINDOWS FIRST!
[XPERIA X1 General] teomito:
i've tried the diamond tweak, but it doesn't work, someone can write a registry key to upload? thanks
[XPERIA X1 General] teomito:
I've done what you told but nothing seems to be changed, is that file to be modified? can you boost it a little more?
[XPERIA X1 General] teomito:
I have it!

The base key is

HKCU\ControlPanel\SoundCategories\Attenuation

There are three values below that 0, 1 and 2. General sound is associated with category 2 and this is probably set to 1 at the moment. I have changed the value associated with category 2 to 3 for the moment. I have heard that it can be changed to as high as 5 but I don't want to damage the speaker.

So in short change the HKCU\ControlPanel\SoundCategories\Attenuation\2 registry setting from the default 1 to a higher value (between 1 and 5) and this will factor up the volume for most phone functions. Once you've done that power cycle the phone for the change to take effect.
[XPERIA X1 General] Bxsteez:
I do not have this key in my device.
[XPERIA X1 General] fards:
Im afraid that made no difference my ringtone when I tried it, went from 1 to all the different values up to 5 with a soft reboot inbetween, but the ringtone remained the same level.

I also tried this one.

http://discussion.wmexperts.com/showpost.php?p=1474659&postcount=252

which caused the ringtone to go silent.

then there's this which explains it a bit.

Audio Categories and Handlers – Source: Microsoft.com and HTC

HKCU\controlpanel\soundcategories\attenuation\

0 =0 Default=0 Muted During Call

1 =1 Default=1 Attenuated During Call – Affected by system volume

2 =2 Default=2 Attenuated During Call – Unaffected by system volume

Add the following to \Attenuation\ (d-word)

3 =3 Create Muted During Call

5 =5 Create NOT Attenuated During Call – Affected by system volume

6 =6 Create NOT Attenuated During Call – Unaffected by system volume

So if those is true all those people claiming it makes their music louder are hearing a placebo effect.
[XPERIA X1 General] EdLow:
I'm having exactly the same problem.

However when I play the mp3 that I've set as my ringtone in the music player either the system one or the Touchflow 3D one then the music is very loud.

To give you a reference the music is played almost twice as loud at full volume.

So I how do I make the settings that the music player uses work for my ringtone settings.

Ed
[XPERIA X1 General] EdLow:
I've just checked my settings.

I don't have the HKLM\Drivers\BuiltIn\WaveDev\AcousticFile in the registry.

Under WaveDev I only have the following options:

Dll, Flags, IClass, Index, Order, Prefix, Priority256

On the phone in the Windows directory I have the Audiopara3.csv and Audiopara3_XC.csv files.

Can you tell me if I need to add the AcousticFile key and if so what the value is for the key. If not then which one of the CSV files do I replace.

Will a soft reset be needed afterwards.

Thanks

Ed
[XPERIA X1 General] fards:
try calling it Audiopara3.csv but make sure you back up the original first.

Soft reset to test it, if it makes no difference try calling it the XC one. If sound ringtone disappears then restore the original!
[XPERIA X1 General] downloadtest82:
I think this is more a mechanical (acoustic) issue than a digital one.

I've noticed that while just sitting on the desk the volume is quite loud for both music and ringtones. However the speaker's sound is released only through this tiny gap on the lower left side of the housing, which is easily covered when the phone is put into a bag or pocket.

Once that hole is covered the speaker becomes almost inaudible because the sound waves created by the tiny speaker simply have no way of leaving the phone's housing.

It's a bit like sealing the resonance tubes of a subwoofer with a pair of socks, except that a 600W-Subwoofer will most likely punch it's way through the obstacle, while the sound wave generated by a 0.1W phone speaker just flatlines upon impact.

To me this is a fundamental mechanical design flaw, I don't think it can be corrected by software.

The "right" solution would be to drill a larger hole into the housing next to the speaker, so the sound waves can spread more easily, but that's probably not an option for most people.

Of course one can try to increase the software amplification factor limits, but since these limits are generally set according to hardware limitations you will very likely not get the desired results, just blow out the speaker or overload the driving transistor...
