Cannot extract TWRP backup (Unexpected type: twimage) #7

Open ghost opened 5 years ago

ghost commented 5 years ago

I get the following error message when trying to extract a TWRP backup archive:

$ twrpabx twrp-20180821.ab 
Input file: 'twrp-20180821.ab'
Read 512 bytes
TW ADB Backup Header type: twstreamheader
Number of partitions: 3
Read 512 bytes
Unexpected type: twimage

I previously generated this TWRP backup with the following command:

adb backup -f twrp-20180821.ab --twrp boot data system

I have a Samsung Galaxy S2 i9100 phone running LineageOS.

I've opened a pull request for this.

I have built the programme using your twrpabx.cpp, but it still fails, albeit with a different error message:

Wrote 1048064  bytes
Remaining bytes in backup file: 8169466880
Read 512  bytes
Corrupt start of data header
wimage

Tried this with two different backup archives. Apparently more work is needed.

This pull request fixes only issue #7. Your problem comes from separate issue #4, please take fix for it as well (or use all-in-one from my git branch).

I now did compile it all from your branch, but the problem is still there. After the boot image it throws the towel with a "corrupt header" message. Are you sure that the fix is in your branch? In #4 @hrimhari says that he has a fix and will create a pull request, but I don't see that he actually has done so.

It's right there: https://github.com/arifogel/twrpabx/pull/5

By all-in-one (issue 4+7) I meant branch on my git: https://github.com/prudy/twrpabx/tree/img_and_issue4

@hrimhari @prudy a big thank you to both of you!!
