Still getting same errors for them partitions not mounting but extraction seems complete what actually happens when it mounts the partitions ?
ive tried 18.04 18.04.6 and 21.04.03 and ive tried various android 9 imgs https://forum.freaktab.com/forum/tv-...fi-bcmbt-qcabt

ok i think ive sorted it whats happening is when you do another rom if you havnt cleared the out folder of level 1 extraction it will just use them to extract and not the new ones that dont seem to be created can the clean up clean img-unpack folder too that would fix it

Yes, but the out folder is not mounted, it is simply created during the unpacking process and does not affect the mounting of partitions in any way.

ye the point is the .partitions inside the "out" folder sometimes dont get replaced with the new ones so when it comes to mount it cant do anything with em cos there already done and really this is a big problem cos i just did 2 different roms and ended up with em both having the same system and vendor partitions and you get boot loop but if i remember to delete the out folder before starting a new rom then the output is perfect and the roms work fine
Im happy deleting the folder myself but it really needs doing with the tool to stop this happening or find out why the .partitions arent always replaced when you do a new extraction

Ive done a few different roms now swapping out system files and apps and they all work great if i do the above. thanks for making it so easy if you need any more testing to get to the bottom of this im happy to help

I can't quite understand it - build script automatically deletes the partitions in the out folder before the newly created partition is copied over. Please post build log

log of 5 runs with 2 different imgs seems the first img has the mount probs and second run is missing all the unpack msgs and inherites the mount probs and when i go to edit system i still have a copy of img 1 system
before the 3rd run i delete out folder and now i get no unpack and no mount probs and i have img 2 system to edit
run 4 is with the img 1 again but this time no errors with mount but missing unpack msgs and i still have img 2 system to edit
run 5 i just delete out folder again and is a copy of the first run to show this img has mount probs

I dont think the problems are related and the img 1 with mount probs seems to extract ok

Invalid sparse file format at header magic
Failed to read sparse file

The IMG you are trying to unpack was not compiled by android 9 sdk. The partitions have already been edited by someone and repacked incorrectly

[wadger]

yes its strange but both imgs run well on my box ive run the mod partitions on it and it fixes the mount problems and it still works fine but i still have to delete the out folder if i want to edit a different img

[bumerc]

That is correct and appropriate. To do this, run make clean. If you want to clean the output directory in bc-tool, run make bc-clean and select option 2.

P.S. The tool repairs the incorrectly compiled partitions automatically.

[wadger]

option 2 dosnt delete the .partition files in /afck/out/amlogic/device/1-2g/img-unpack If they remain any imgs done after dont get dumped you can see it in the logs this bit gets skipped on second run if you dont

the log of the forth run shows the img 1 with bad partitions extract and mount fine cos its using partitons from img 2 i didnt delete out folder
i know this is happening because 1 of my imgs has an extra file in system so i can tell easy which one im looking at
I dont really understand why these partitions aren't deleted when you press option 1 cos that would be perfect

I just want any that use this tool to know if you work with different img then you must delete in my case/afck/out/amlogic/device/1-2g/img-unpack or /afck/out is fine for everyone
the way option 1 works now is fine if your running the same img all the time cos its quicker (it doesn't redump the .partitions) so maybe option 4 can be working with new img and it runs 1 2 and 3 and deletes the out folder ?

the “make clean” command deletes the partitions in afck/out/amlogic/device/1-2g/img-unpack, I mentioned that earlier. The “make bc-clean” command is only active in the bc-tool and does not spread to afck. This is also described in readme.md.

Thanks. I didn't notice the make clean command sorry for all the hassle, Moving on, now wearing my glasses :-)

Post the old and the new fs_config text files. Apparently something has not been declared in fs_config.
