Sorry for this potentially stupid question I'm relatively new to the Xperia TA / DRM stuff.
Back in October when I unlocked the bootloader and rooted my Z3 compact I created what I thought was a backup of the TA partition. Now I *think* I did this using flashtool as I have a .zip file called "flashtool TA files" which contains 3 files:
FILE_281312136 110 KB
FILE_281516736 21,363 KB
FILE_281528010 791 KB
Now does anyone know whether this is actually a usable backup of my DRM keys or is it pointless keeping these?
Thanks

The TA partition is 2MB, so a dump would be 2,097,152 bytes exactly. Doesn't appear that any of those are TA backups.

I was supposed to provide the file but my net connection died halfway during download T.T

BUMP anyone ??
It takes only 10minutes provided you are running ICS 4.0.4 :l
I'm currently uploading CWM system of 4.0.4 for Arc to Google Drive, but I have slow upload so it will be around 45-60 minutes at least before I have a link for JJ.
This is compressed system and data folder.
Not CWM, not img
LT18i_4.1.B.0.431_1254-2184.7z
http://www.mediafire.com/?113dp1ywv43c532
This is compressed system, data and vendor folder.
Not CWM, not img
LT15i_4.1.B.0.431_1247-1046.7z
http://www.mediafire.com/?c6d3f0qyuo4quso
PS:
IF you add META-INF and proper update-script, can be used for CWM updating
This is CWM backup of the system image LT15i_4.1.B.0.431_Generic World FR :
https://docs.google.com/open?id=0By9xc2HbjMA6dS1vcUV1eHlQdnM
and this is the rest of the CWM backup in case anyone wants it:
https://docs.google.com/open?id=0By9xc2HbjMA6elMwZ0lwX3pjVzg
Take no notice of the date on the files being 1980. I took the backup before the first startup so that there would be no changes to the files and the current time wasn't set at that stage.
Both parts are 7zipped.

Warning, LT15 CWM system.img backup does not contain all files. LT15 has also vendor files, about 90Mb.
If you format system partition, and restore from those backups. You will lose lots of apk. FC everywhere
Suggest you to use LT18 files, less bloatware (LT15 has annoying France applications)
Thank you guys for the links... It made sure that Arc update comes side by side with other devices...
I am on it and done with 90% of the ROM... Only one bug to fix and then its ready for release...
Needed these Arc files to ensure you guys get Original drivers optimized for ur devices and not some ported one...
even if I couldnt manage those bugs I will come out with a Fully functional test release in 24-48hrs....

Huh?? Since you only uploaded zips I assume you are referring to my CWM backup img. What files do you claim are missing?

Can someone else confirm this claim? Which apks are missing?
I just formatted system and restored from my CWM backup, a short while ago, when I saw this post. I don't see anything missing, and no FC.
If there really is something wrong with my backup that I can't detect, then I apologise. But, since I have been able to restore successfully without problems, I'm not convinced.

You dont need to worry about that... I know what to do ..

Looking forward to the ROM
Should this be stickied so that other Devs can make use of arc libs directly ?
Hello,
I am a bit anxious about my phone. It works well under omega 3.1 but I was checking my saves and I foud that:
1) My EFS folder is empty
2) I have two efs backup files but they seem rather small (35k each) ans they are dated 1970 I am pretty sure they are empty
3) my IMEI is correct when I go into about phone (But does not appear when I dial *#06#
Is there something wrong ?
The Imei seems good but as the efs folder is empty it should not...
Any idea ?

I am not sure how to do it with terminal emulator.
After flashing TWRP recovery and while the phone was brand new I made a full backup of the phone and inside there is a efs backup wich is 35k
Also I made another backup made with twrp recovery and it is 35 k again for the efs.ext4.win
Is that a normal size ?

I did it and it created a 13.62 mb file.
However I dont know if there is something inside as there is no file in efs folder. It may have copied blank data ?

it doesnt matter if you dont see it. the efs partition is fine

Yes I did it also for the m9kefs partitions and everything is stored in safe place.
Many thanks to you !
My efs (files and folders inside) is 3.xx kb and is correct.
The whole partition of efs is about 13.xx mb.
Even the efs folder has no files in it or have,
the size of the partition remain the same.
Thanks.

Thank you. Yes :thumbup: i was pointing to the whole partition. it seems that his efs partition is not corrupted. I suggest always to backup the whole partition.

And any idea why the efs folder is empty ? Is the efs a hidden partition and the folder just a dumb file or symbolic link ?

what explorer are you using?
download attached file manager, install it. open it, go to the settings of file manager, check "root explorer" (grant permission) and check "mount system folder". now see efs folder.
Hi,
I have made a few efs backups using aroma installer with X Note and Omega Rom and have ran that .bat command and I end up with my efs backup at around 116 kb.
Does this sound about right?
I have read about some efs backups being around 20mb.
Thanks for any help.

Is there a way to restore/create a .ta file without having backed up it before unlocking bootloader? Or is there a way to fix the errors that come losing it? I've an Xperia XA1
