Hi,

 I have a similar problem as described in this post here https://bitcointalk.org/index.php?topic=5148367.msg51495973#msg51495973 .
 I have a mycelium android wallet but not used for like 2 years  and i kept adding accounts to it. Today i went to the atm to withdraw some bitcoin only to realize that my pin is incorrect.
 I tried to restore wallet with the backup seed phrase on my wife phone but only one account was restored and not the one with bitcoin in it. I already entered the pin 2 times wrong im afraid to try again, i don't know haw many times you can enter it until they luck up the application.
 I read the other threads on this subject and im trying to recreate Bob123 post " Since you still have full access to the device, you can enable USB-debugging in the settings, then connect to your mobile with your PC (via adb shell) and backup any necessary data (in this case: all data from mycelium).

Afterwards you should even be able to extract the mycelium pin from the backup on your computer.
The pin can be found in:
Code:
/data/data/com.mycelium.wallet/shared_prefs/settings.xml

You also should be able to extact the master key itself, which is stored in a sqlite database.

That's a bit more complex than simply rooting the phone and reading it out, but you can try this first without rooting your phone.
And you will have a backup of all necessary files in case you do something wrong when rooting your mobile." but I'm stuck.

 The phone is a Hawaii P20 light not rooted, i managed to pull com.mycelium.wallet but i don't know what to do next, haw to open it or if it the pin is in that file.
 
I'm no programmer, i don't know what command to enter next, i just fallowed you tube videos and what i could find on the internet.

 I'm not rich, the address has around 1.500$ in BTC . I Dm Bob123 but he has not been on this site for the last 10 days the site shoes.

 Any help will be deeply appreciated, thank you

 here is where Im now :
