Error -3 while decompressing data: incorrect header check

You have a not valid key for that backup or you have a different offset #96, #113, #120
i put valid key but every time same error occurred! please help me
is there any other salutation.
If you follow this thread #113, maybe @ElDavoo can solve your problem. Be careful when extracting the Key because if you are not root the key can change.
I am trying to know if the key file is identical for both crypt12 and crypt14. If you install the latest version of WA and restore from old crypt12, the App will not convert the db to crypt14. The decryption works for old crpt12 db, but not for old crypt14 db. Are the key file different for each?!
Can you elaborate? ☺ Is it possible to use the key file associated with crypt12 to decrpt a crypt14 db at all? I read somewhere that changing the offsets may work.
the key is always the same, unless it changed for other reasons. you need to use recent versions of programs to have updated offsets
I registered again using an emulator and pulled a different key file! The decryption process still fails.. I think I am using the last updated version of the script. Installing the pycrypto and pycrypto dome was failing due to vcvar...bat and was later fixed by getting an MSI version of the binary. However, it gives run errors for some odd reason. Regards..
same error
[e] An error has ocurred decrypting '/home/mc/Desktop/msgstore.db.crypt14' - Error -3 while decompressing data: incorrect header check
OS : Kali linux key and database are same
Had the same problem, but decrypting worked with https://github.com/ElDavoo/WhatsApp-Crypt14-Decrypter/blob/master/decrypt14.py
After comparing the offsets, I got whacipher.py working by changing the offset in line 79 to data = db_data[190:] (notice: 190 instead of 191)
Hope this can help someone
Basically in the database header you have the WhatsApp version, whose length often changes. Example: "2.21.24.22" => 11 bytes => offset=191 "2.22.3.77" => 10 bytes => offset=190 "2.22.5.7" => 9 bytes => offset=189
So yeah using a fixed offset won't work.
