[Sony Xperia S, Acro S, Ion] RHBH:
I don't know anyone that tested.

And I have no idea because Xperia P is a NovaThor device not a Qualcomm device like the confirmed working devices (Xperia Z, ZL, ion).
[Sony Xperia S, Acro S, Ion] RHBH:
I'm thinking in unlock my BL to test the 6.2.B.0.200 FW, the only thing is holding me is the fear, because I would restore TA (lock BL) when the official JB rolls out and this was confirmed working only for Xperia ion.
[Sony Xperia S, Acro S, Ion] FenrirMX:
Ion and S are basically the same, except for the LTE radio present in the Ion (which should make no difference with regard for the TA partition). Although, I can understand your reluctance to experiment.
[Sony Xperia S, Acro S, Ion] Szatyor:
Maybe I will test on SL

Hello guys!

Excuse me for the noob question, but my english is not so good. If I understood correctly, this method may can work on S, but it's not tested (except the hard bricked S). But now the tool can do a dry-run, when do not write the TA partition, and the program can be check the compatibility for the device. I'm asking because I would like to try it, but im scared of that, because I have an Xperia SL, and nobody reported a sucsessfully restore on S. But if somebody want, I can make a backup before, and after I unlocked the BL, and he/she can analyze these files. :)
[Sony Xperia S, Acro S, Ion] lee480:
It should work too. Ion, S, SL, Acro S uses the same chipset.
[Sony Xperia S, Acro S, Ion] Szatyor:
Well, I think I will try it. Just my phone need for a little time to charge it up.
[Sony Xperia S, Acro S, Ion] s-X-s:
Do a back up and transfer your sdcard contents to pc before doing it....i made such a mistake lost backup files 15gb contents as my phone needed a motherboard replacement/replaced by new phone(well they said board replaced, but one i got appears nothing like my old XS :p)
[Sony Xperia S, Acro S, Ion] Szatyor:
I already wiped the phone's storage, because I can copy the important files to my phone again, when it survive the "relock". :D But first, I'll pray for a sucsessful restore, because my second phone is my old SE Live with Walkman without power button.
[Sony Xperia S, Acro S, Ion] FenrirMX:
Well, Godspeed, man. Wish you the best of luck, your results will definitely influence my decision, lol.
[Sony Xperia S, Acro S, Ion] Szatyor:
I think it can't be sucsessful. I don't understand, because I made this backup yesterday, when my phone was same. But in afternoon, I will try it again with a fresh stock ROM. Not with this, what I flashed yesterday. (Excuse me for the picture, but I needed to hurry to school) https://docs.google.com/file/d/0B_z0ehg02t_oQ2t2YW9ON2x4TUk/edit?usp=sharing
[Sony Xperia S, Acro S, Ion] FenrirMX:
Did you try it with DevShaft's latest version?

There was a bug in the previous one that caused it to always think it was from a different device.
[Sony Xperia S, Acro S, Ion] Szatyor:
Ok, maybe that's the problem. I just have the v8.5. I will download soon and try it.
[Sony Xperia S, Acro S, Ion] Szatyor:
Result of the backup on SL

Sorry for the another reply, but I think now it's too important for an edit my last reply! I tested what happens, when we restore the original TA on Xperia S/SL. The result is... Everything works fine! :laugh: The bravia engine works fine, just like the music info download, and the TrackID.

I used the following things for the test:

My Xperia SL (the phone is independent from any carriers)

Flashtool

Stock 6.1.A.2.45 Generic ROM

Backup-TA v8.5 (after 8.6)

And a Google translate
[Sony Xperia S, Acro S, Ion] RHBH:
So it's confirmed working on Xperia ion and Xperia SL, I'll test on Xperia S.

Thanks for your report, I'll unlock my bootloader and test the .200 FW.

When Sony release JB, I'll flash JB FTF then restore TA and enjoy DRM content again :)

We need someone to test it on acro S.
[Sony Xperia S, Acro S, Ion] Szatyor:
On the S, it will work too, because the S/SL dou has got same board, just the SL is faster a bit. It's a pleasure, and I was so interested to. ;) Well, let's see on Arco S, and maybe on the other Qualcomm device.
[Sony Xperia S, Acro S, Ion] RHBH:
Just to clarify and confirm what I'm going to do:

I'm running Stock .55 ICS rooted with locked BL.

1- Backup TA (already did that sometimes).

2/3 - Unlock my BL and enjoy the custom roms / kernels.

2/3 - Install CWM.

4- Flash leaked .200 JB rom and DooMLoRD's kernel for leaked JB.

Until here I'm ok, I have some doubts.

- Which CWM do you recommend and should I install CWM before or after unlock BL?

I'll restore TA when official JB FTF arrives (and consequently relock my BL with DRM keys back), when I restore, Should I be on Stock .55 rooted or Can I be running the new FTF?

Basically I have two options:

Option 1

4- Flash Stock .55 ICS and Kernel with the FTF using flashtool.
5- Root the phone.
6- Restore TA.
7- Reboot the phone and check if everything is Ok.
8- Flash the official JB FTF using flashtool

Option 2

4- Flash the offical JB FTF using flashtool.
5- Root the phone (the BL is unlocked).
6- Restore TA.
7- Reboot the phone and check if everything is Ok.

Option 2 MAY keep my JB phone rooted with locked BL. I saw some guys on XZ's forum using the backup/restore as a "trick" to root the phone and use locked BL.

So, which one?
[Sony Xperia S, Acro S, Ion] Gallardo994:
Basically 1st method must be more reliable. But 2nd one is possible too
[Sony Xperia S, Acro S, Ion] Szatyor:
These steps are correct. Well, I recommend to turn back to the .55 before you lock the BL, because that was the basic system before the unlock. And if you lock the bl with an unnofical kernel, it may cause problems. If my memory is good, DooMLoRD only relased the .197 JB leak, the .200 is just for brown devices. But these are not facts, because, nobody tested this yet. If the offical JB FTF will come out, maybe I can test it.
[Sony Xperia S, Acro S, Ion] RHBH:
Actually DooMLoRD's kernel for .197 is working for .200 (I think Sony devs used the same kernel for both versions).

Also I won't restore TA using unnoficial kernels (both options I would use the FTF file [.55 or official JB) that have kernel.sin [official Sony kernel], I know that if I do so, I'll soft-brick my phone.
[Sony Xperia S, Acro S, Ion] Szatyor:
It's okay. I just misunderstanded you with the JB. If the "197" kernel works with the 200, it's no problem.
[Sony Xperia S, Acro S, Ion] RHBH:
Before proceed I'm asking for help on the .200 leak topic about which cwm to install and the steps to do for install.
[Sony Xperia S, Acro S, Ion] Szatyor:
The kernel is include a CWM (6.0.2.7). Actually I testing too the 197 JB leak. So you don't neec to install a CWM. But I think it's not a best idea to talking from this in this thread, because we are make an off.
[Sony Xperia S, Acro S, Ion] Lodotux:
So, untill now, we know it works on Ion and SL devices, but no one have tested it it on S so far ?
[Sony Xperia S, Acro S, Ion] newdon07:
if it worked for XSL, I am pretty sure it'll defintly work on XS as well!! :)
[Sony Xperia S, Acro S, Ion] Lodotux:
Yes I think so too, but my phone is only 1 month old, I won't take chances until I got some confirmation... :p
[Sony Xperia S, Acro S, Ion] RHBH:
I unlocked my XS to test .200 JB build. When oficial JB comes out, I'll flash stock .55 back, relock restoring TA and if everything works, update using PCC/SUS or flashing a FTF file.

So if you wait until JB comes available I'll confirm if it's this working or not on XS.
[Sony Xperia S, Acro S, Ion] Lodotux:
I'll wait... hopefully JB won't be long
[Sony Xperia S, Acro S, Ion] RHBH:
Testing TA restore on my Xperia S now.

In some minutes I'll give an update.

UPDATE

I can confirm this method is working for Xperia S. Used [MENTION=5261329]DevShaft[/MENTION] Backup-TA Tool v8.6

I successfully made a backup, unlocked my bootloader this monday (may 27th), restored my bootloader today and now is showing "Bootloader unlock allowed: Yes", tested music info download and is working also.

Also I discovered two things:

There is no need to backup and restore using the same FW (my backup was made with 6.1.A.2.55_1257-6921 and restored with 6.2.B.0.200_1257-4001).

TA backup / restore is working for root while unlocked BL and keep rooted while locked BL.

[Sony Xperia S, Acro S, Ion] shion420:
Hello, i have a question, somebody did a backup with the first version of this program? i mean , if a have a backup for the first version it would work fine if is restored? or it was buggy and the backup got corrupted or something? i just want to be sure when i restore the TA partition, thanks.
[Sony Xperia S, Acro S, Ion] RHBH:
If you're goingo to restore using the same version, no further action needed.

If you're going to use the actual release (v8.6):

1. Make sure the image (backup file) is named TA.img

2. Make a new file called TA.md5 and in this file save the MD5 hash of TA.img.

3. ZIP both TA.img and TA.md5 in a ZIP file called TA-backup.zip

4. Save this ZIP file in the 'Backup-TA\backup' folder.
[Sony Xperia S, Acro S, Ion] jaxzkeren:
hi ... i only have TA.img using terminal, so how to make this MD5 hash ?

or can i just terminal and give command dd if=/sdcard/TA.img of=/dev/block/mmcblk0p1 ?

thanks ...
[Sony Xperia S, Acro S, Ion] RHBH:
Download the md5.exe and pleace at your Backup-TA folder and execute the command:

cd C:\Backup-TA

md5 TA.img

Then you'll see the MD5 of your TA.img.

This is the value you should write in the notepad and save the file as TA.md5 save it as ANSI (remove .txt and left .md5 extension).
[Sony Xperia S, Acro S, Ion] jaxzkeren:
thank you ... :D

but when i try restore dry run, when extracting ' everything is ok ' , but on integrity check ' failed ' , restore unsuccesful ...

did i miss something ?

thanks ..

and dont forget, do this before you unlock ..:)
[Sony Xperia S, Acro S, Ion] ARNOB:
My TA image size by flashtool is 132kB. TrackID, Download Music Info and Bravia Engine in Album works!

My device: Xperia Ion.

What I did:

- Being on XZXv2 Locked bootloader, I made a backup of TA image using flashtool.

- Then I unlocked the bootloader, tried leak JB, MIUI and Paranoid Android.

- Then flash stock 6.1.E.2.68 fw and restored TA image.

- Still I got Bootloader Unlocked = Yes

- Then flashed Relock bootloader ftf and it turned into Bootloader Unlock Allowed = Yes

- Updated to latest 6.1.E.3.7 via OTA and again flashed TA image.

- I successfully relocked bootloader and restored DRM keys! :victory:

I found that restoring TA using flashtool does not relock bootloader but it does keeps the DRM keys safe.
[Sony Xperia S, Acro S, Ion] RHBH:
Sorry to finish your happiness, but restoring the TA should had restocked your bootloader, something you did is wrong.
[Sony Xperia S, Acro S, Ion] ARNOB:
That was what I was thinking as well.

TrackID, Download Music Info and Bravia Engine is working after relocking at stock unrooted ICS (this should break after once bootloader is altered right?). I tried Download Music Info before but that didn't work while on GI Kernel (UB).

Now what is happening, any explanation? I can post screenshot if you want.

Edit: I tried backing up again, the new one is 132kB as well. :/

[Sony Xperia S, Acro S, Ion] mirhl:
It doesn't create the key from nil

If you had -previously to unlocking- made a backup.. then your keys will be back

Otherwise, nothing will change (apart from relocking your bl if it were unlocked)
[Sony Xperia S, Acro S, Ion] jaxzkeren:
confirm , this tool work perfectly for restore , but only if you made backup BEFORE you unlock bootloader .....

so if you already unlock your bootloader then your keys lost forever .... ( but then again, it's just BE on picture only ... some people prefer to turn BE off so they can see the real picture on album ..... BE still works on video, TrackID works to .. ;) ;) )

just be carefull and read the instruction .... ( and off course there is always risk, so be carefull ... but i already test and it works .. )

for other who has already unlock, like mirhl says, they still can relock if they wants to use sony update ... :fingers-crossed:

So I've just restored my TA, but.. I can't seems to differentiate whether it's working or not through bravia engine lol, since all the images looks the same to me whether I turn it on and off.

But the TrackID works fine though, so I assume everything is working like before it was unlocked then?

Also, before I flash a stock rom again/unlock bootloader etc, do I need to perform the backup thing again? or can I just reuse my previous TA image?

Sorry if these has been asked before, and thanks! :)
[Sony Xperia S, Acro S, Ion] mirhl:
Bravia engine effects can be checked by comparing screenshots taken with it enabled/disabled

TrackID (if ever needed that) doesn't require that since ages

[Sony Xperia S, Acro S, Ion] Marsou77:
As fast as you restore your TA.img, your bootloader will be locked again. Since there is some security check between bootloader and kernel, you will brick your phone.

with that method, you load on the phone developers DRM keys

which (i suppose) on retail devices works only for bravia engine

with the method of this thread, you get your phone back like it was before opening the box

music info download and BE2 is fully working

you mean i can do it?
[Sony Xperia S, Acro S, Ion] Marsou77:
No ! If you flash your own partition when you are with another kernel than the stock one. Example :

-If your are on CM10, restore your TA image will brick your device.

-If you are on stock based rom with a custom kernel, restore your TA image will brick your device.

-If you are on stock or stock based with stock kernel, restore your TA image will work.

This is how I understand the thing. Maybe I'm wrong but it seems legit.
