getting "Failed to pull database by adb" about wechat-dump HOT 11 CLOSED

Well, the script cannot get the message database from your phone.
You can check if the following files or directory exists, by running several adb command:

adb root  # start adb daemon as root
adb ls /data/data/com.tencent.mm/MicroMsg  # wechat data directory, this directory should contain one or more sub directories with a long random name
adb pull /data/data/com.tencent.mm/MicroMsg/long-long-name/EnMicroMsg.db  # copy the database file

You can manually check if the above files & directories exists, and see if you can successfully copy the database file.
If not, probably in your phone files are not in usual location. Then I have no idea. You can look at those directories to figure out the correct location, or list some directory contents for others to take a look.

So i managed to pull my desired directory from the phone manually, but I am still stuck at decrypt.db

adb is running as root

able to list and pull directories from /data/data/com.tencent.mm/

Am i missing any step?

from wechat-dump.

The error is indicating a broken database or wrong password to decrypt the database.
This is either due to a wrong IMEI, wrong UIN, or that things may be different on different phones/OS. I also received similar complaints here: #12, and he managed to solve it by migrating to another phone.
There are different ways of getting IMEI from a phone listed in README.md. I'm not sure if they are equivalent but you can have a try.

from wechat-dump.

I used my own sqlcipher (3.8.8.3) on Mac and have to add PRAGMA cipher_page_size = 1024 and PRAGMA kdf_iter = 4000 to make it decrypt. Maybe you could try that by modifying the decrypt-db.sh.
Ref this article

@wang0109 Thanks for your note! Did you test my version of sqlcipher and did it work? I want to make sure is it a different method of encryption, or just two version doing the same thing.

Also, from that article, it looks like UIN could be a negative number, which I didn't know about. This can also cause error in decryption.

@ppwwyyxx I did try the included sqlcipher first, unfortunately I got:

KEY: fe05521

I didn't figure out how to fix that mismatch error, so in the end I figured I just use my own sqlcipher instead. Thanks for the great tool btw!

from wechat-dump.

Thanks! I tested the method in that article, and it also works for my database.
Looks like it might be a better approach since it works for both of us. I updated the code for this.

from wechat-dump.

@ppwwyyxx So by updating this decrypt_db should be able to eliminate my db issue?

from wechat-dump.

@magichand I don't know what's the exact problem in your case, but you can give it a try.
Start from the very beginning because I also changed the code for getting UIN. I didn't know it could be negative before.

from wechat-dump.

Also, could you add your device and OS information at wiki so people may have an idea of the exact reason in the future?
@magichand @wang0109 Thanks a lot!

I'm using OnePlus One, loaded with CM12.1 (Temasek flavor).
