Dear B&O Friends,

 

now I have a real dumb problem:
I still have my 2 Serenata phones. One as a backup and the other as an alarm clock with music. It's connected to the power outlet 24h on its nice docking station.
Now we where on holiday the last 2 weeks and I switched off the fuses at home and this time accidentally the fuse for our bedroom, too. The Serenata obviously ran out of power and now I've learned the hard way that I have NOT used the same security / phone lock code on both phones - which I thought. But it's a few years ago and I simply can't remember it. I tried my standard code which works on the backup phone and the factory standard code: No luck!

So, one of my Serenata phones is now completely useless and only a paper weight as it is locked! Is there any way to unlock it  and use it again?? Can my B&O dealer help me or is the phone too old?

TWG, 

here some suggestions to get into your phone's recovery mode, I hope one of them will work, because of its Samsung software:

Your phone must be powered off before starting!

 

1.

Try holding the volume up and the home button,

2.

or volume up and down buttons.

Whilst doing so, press the power button for 2-3 seconds, release but maintain the press on the volume button.

If you get into Recovery Mode, use the volume down button to select Wipe Data and press  the power button to confirm. Use the volume button again to select the final confirmation.

3.

All at the same time press and hold the volume up, home and power button.

When the phone boots, you hopefully will be in Recovery Mode. Use the volume buttons to scroll down to reset and the power button to select the option.

Then scroll down using the volume button again to select Yes – delete all my data to confirm the factory reset.

4. 

At the same time press and hold the Power/Lock for 10 to 15 seconds until the screen flashes on.

Use the Volume Down button to scroll and the Volume Up button to select Recovery.

Press the Volume Up button and Volume Down button together at this screen.

Use the Volume Down button to scroll down and the Power button to select Factory Reset, press the power key to confirm.

Use the Volume Down button to select Yes – delete all user data – and press the power button or the Volume Up and Down buttons again to confirm.

Hopefully the device will then start performing the Factory Data Reset. Once the formatting is complete, press the Power button to confirm a reboot.

 

If it works and I hope so, your phone will be as new, like it was when you bought it.

Good luck to you!

Hi Ulrike,


thanks for your hints but unfortunately nothing of this works and the button combinations are nearly impossible to press due to the wheel design of the Serenata:

Any other hints except that I could use it as a paper weight? Wink

Okay Confused  :)

Is there a Sim card inserted?

In any case, power off your phone and remove the SIM card if there is one.
Insert an active SIM card (need to know the pin code) from a different carrier and power your phone back on. 
Now try to type on keyboard *2767*3855# 

Maybe, maybe it will work?

If it does not, I would try to contact Samsung customer service:

https://www.samsung.com/us/support/contact/

You will need to know your phone's IMEI and serial number - remove the battery.

Yes, there's always an old signed out SIM card placed in my Serenata as it wouldn't start without one. 

I've found this solution, too but there's NO way to enter "*" and "#". You only get a dial with numbers and "Enter". Sad

*2767*3855#

Forgotten:

There should be an option to insert this code by typing on the keyboard under "Emergency Call"

Hope it works ...

Just had a look at the manual ...

It's not possible when locked?

Thank you Ulrike for your effort!

 

This is everything you'll see: 


 

 

Lessons learned:
- Ensure to use an identical lock code on identical devices
- Write down every code for every device

Embarrassed

As there is shown on the display:

"Sim-Sperre"

I REALLY would insert another Sim card with pin code known!

Guess it will work then.

This is NOT the screen for entering the SIM-Pin, it is for the phone lock code! You have to enter the correct SIM Pin before the screen shown above will appear. I use this phone for years and it's always (if used) the two code authentification: 1.) SIM Pin and if this is correct you'll forwarded to 2.) Phone lock. 
As stated the "Phone Lock" is the big problem which currently prevents me from using the phone again.

Just one thing ...

If I would try to hack my phone, I would think about this again, you wrote:

I have NOT used the same security / phone lock code on both phones - which I thought. But it's a few years ago and I simply can't remember it. I tried my standard code which works on the backup phone and the factory standard code: No luck!

One reason for not writing down the code for the other device may have been that you thought it wouldn't be necessary, because there wasn't so much a difference ..

I would try:

Take that standard code, type a 1 before - or a 2 before. Or a 1 or a 2 behind.

Thank you for your help! I tried all these things before writing the first post here. ;)

I'm gonna visit my dealer and ask him what to do. Seems to be the only way.
