Xperia S Stock Firmware 6.1.A.2.55 Deodex Flashable Zip Root

Title should tell you all.
I made it to be easy to flash on unlock boot loader via CWM recovery. Just flash it like other custom ROM.
It also reported to work on Locked boot loader!!
- deodex framework and app
- remove few bloated app recommended by ROM kitchen
- busybox installed
- ready for init.d tweak
- ready for user app.
Installation test with SSpeed V7 normal kernel and Advanced Stock Kernel ICS16
It work on my Xperia s I hope it work on your as well.
https://hotfile.com/dl/180118347/fd5551c/LT26i_6.1.A.2.55_SG_Stock.zip.html
The goal of this ROM is a clean stock ROM but ready for mod easily by using just 7zip and notepad++
For example to get quick panel toggle just download the mod somewhere in xda then open the ROM with 7zip (do not extract) then replace systemui and add quick panel setting apk in the system folder. That is!!
You can also add your favor app in data/app to make it preinstall with your new ROM.
Have fun with modding and share your work.

Great Job.

I think you can use titanium backup to backup your game data. Just to be safe please do binary backup of the whole system in CWM before you flash new firmware.
When I test on mine I always do a clean install to eliminate unforeseen problem. I wold recommend you do the same.

works for locked boot? : Confused:

Ok. Btw can you spot any difference in this new update?
Is battery life good?

my bootloader is locked
and well i went ahead and flashed it (just to prove my theory) and it worked...
my previous rom was .50 rooted and had CWM installed also
i already had flashed .55 kernel and baseband only thing missing was .55 sys
i flashed this zip
it booted and phone is now finally fully .55 and rooted
only thing i had 2 reinstall was CWM because this zip doesnt have recovery in it
thanks! :good:
any chance of same rom with root but in original state (with root included ofc)?
i wont post my steps yet cause i think since this is a deodex rom we will have .odex files left over in sys partition (correct me if im wrong)
so please make a zip so i can test and u can then release for all us unlucky bootloader locked Xperia S users
cheers

Hi, I have been following your post for rooting my Xperia S with latest firmware. So while I was following your steps, my phone has stuck at Sony logo after Step 5 . Event after hard reset my phone was still stuck at Sony logo. So, I finally flashed .50 ICS rom using flashtool to bring my phone in working condition nearly after waiting for half an hour. Pcarvalho, can you please help me with this? I really need to root my phone with latest firmware. I am kind of new to all this rooting concepts. I have followed all the steps till Step 5. Please help asap. Thanks in advance.

Why we can't root any build like this way?

Hi:
For one week i was asking my self that when we got new builds that no one know how to root it , why don't we use CWM to force flash su files to system? why it will not work?
I mean if we flashed the root using CWM , the phone must be rooted right?

Ok.
So how do you put in cwm on a new rom without it already installed?

I didn't understand. After flash the stock rom just f;ask custom kernel with CWM then flash the root zip the reflash the stock kernel.

On stock rom (locked bl) you need root to instal cwm, then from cwm do whatever you want do.
Also unlocked BL is always ROOTABLE, don't ask even once for this.
Many newbies on Forum posts that thay found root for unlocked BL, that isnt achivement. Flash custom kernel with root in self.
Trying to root locked bl, well, that is pain in the ass.

As unlocked BL you have few option.
1. Kernel which is pre rooted
2. Rom which is pre rooted
3. Flash some root.zip (depends on rom and/or kernel).

Actually, there is a universal zip file for any android phone which *should* root your phone but very often the installation fails because of a wrong update-binary (Status 0). So I made a zip which should work on our Xperia phones here - http://forum.xda-developers.com/attachment.php?attachmentid=1772586&d=1362200612
Just flash in cwm and enjoy the root access

Yes, i think if we flashed the root (su and busybox package) via CWM or any recovery tool, the phone must be rooted. But in some cases at stock kernel, the CWM doesn't work properly so first of all unlocking bootloader if we flashed any custom kernel (like doomlord kernel) then we can easily get root access flashing the package via recovery.
thanks !

Aha , my idea was to unlock bootloader , flash stock JB then flash ICS kernel+CWM , flash the root.zip then reflash the stock kernel.

It sets the correct permissions on the su binary. Actually there is no need for this file since the updater-script does all the work but while I was working on my rom, the permissions were not getting set properly so I used this script

ROOT firmware .569 and install dual recovery (UNLOCKED)

i tried rooting the new firmware and it was a success, i now have root and dual recovery installed on stock 4.3
here's the other link i posted http://forum.xda-developers.com/showthread.php?p=48805157#post48805157
here's how. (my device is locked BL)
LINKS UPDATED!! (recovery)
1.Backed up my TA Partition
2.Flashed the official .569 ftf using flashtool
3.Unlocked my ZL's bootloader
4.Flash this kernel to get recovery (thanks Minthun46) http://forum.xda-developers.com/devdb/project/?id=700#downloads extract the boot.img and flash it using fastboot or flashtool (fastboot mode)
5.Flash Supersu fix zip and dual recovery (thanks NUT) SUPERSU fix.zip http://nut.xperia-files.com/download.php?dlid=U3VwZXJTVV9maXg=

6.Re flash .569 ftf exclude everything except kernel and fotakernel.
7.Restore TA Backup.
FOR UNLOCKED BL
just follow step 2, 4, 5, and 6
VOILA!!! device is now rooted and has working recovery
PS
Will only work for ZL that can be bootloader unlock.
Hit thanks if it helps you.

Don't put Locked BL in the title, you only managed to root because your phone was unlockable. Putting Locked BL in the title states that your bootloader can also be locked for this method to work, and but unless your ZL can be bootloader unlocked, this method cannot be used for locked BL

[Q] Rooting z1 compact stock lollipop

We all have gotten a sneak peek of Sony's lollipop update onto our beloved z1 compact. Through the many ways available I for instance used an ftf file. But they do not come pre-rooted like the zip file alternatives.
The only way to root ftf I am told is to flash a kernel pre-installed with a recovery then flash SuperSU zip. I have flashed like 3 different boot.imgs only to find no TWRP/Philz/cmw recovery.
Can anyone give me a WORKING kernel that will boot into a recovery? Would really appreciate this.
Found my solution
Edit: I just found a cm11 snapshot boot.img kernel, flashed it. Booted to recovery and flashed a pre-rooted rom zip. Easy as pie.
Thanks all.

Just flash KK firmware 108, root it, install recovery latest version, and afterwards flash any customised prerooted ROM of your choice.

This is too much work. Work that I have to do. It's the only way to root this ftf. damn it

It's up to you.

I've done it.
I made a pre-rooted ftf using PRF creator and compiling the SUPERSU v2.37 and Z1C locked dual recovery 2.8.12 from Nuts site.
You can use Xperifirm to download the the firmware, then use Flashtool to decrypt the fileset and create the FTF, then you're good to go.

I'm from the UK but I used the "Customized US" version. It works all the same, I've put together a UK one now but I'll need to wipe data before I can use it.
I'd share if I didn't have awful internet. The file is massive, unfortunately.
You'll find multiple threads on how to do different parts.
You need to create your pre-rooted firmware, then you'll need to download KK with Xperifirm (probably .108) and flash it with Flashtool.
Root KK using Easy Root Tool and install XZDualRecovery using the desktop client.
Once you're rooted with SuperSU/SuperUser and Recovery you can install the pre-rooted firmware (PRF) as a flashable zip within Recovery itself.
There's also work arounds for Xposed which you can find too, I've used them and it's all working as it should for now.
I also have a locked bootloader, so don't worry about unlocking it. I'll have a look around for the threads I used and post any I find.

I'll leave you to find your own SuperSU or SuperUser zip, same with XZDualRecovery as they're frequently updated so you're better off finding the latest versions.

But how can you flash 108 if you are already on 242 and you have a locked bootloader? You must unlock it first...

What I did is that I downgraded with Flashtool, rooted KK, and then flashed a prerooted rom through the recovery. No need to unlock the bootloader.

How did you downgrade really?
You just flashed the 157 FTF in flashmode? It's doable?

OK, there seems to be some loss in translation somewhere. Hope this will clear up some stuff:
1. Flash KitKat (kernel, system, everything).
2. Root it.
3. Install recovery (here)
4. Since you don't want to make your own pre-rooted firmware, here. Click on 'Google Drive' for the zip, and FTF. You need both.
5. Put the zip in your SD card/internal.
6. Boot into recovery and clear all data (dalvik, system, data, everything).
7. Flash the zip. DO NOT REBOOT.
8. Shutdown and use Flashtool to flash the .ftf you downloaded. Check System and Baseband on the 'exclude' column.
9. Have fun!

@dazzerfong OK,first of all thanks for your answer. What I'm asking is how did you do the first step with locked bootloader.
Flashtool->Flashmode->KitKat 157 FTF->Then root it blah blah?
Are these steps correct or not? Im about to try today cos I really miss root on my phone.
If you are already on Lollipop and your bootloader is locked you can get root this way.
1.Download the correct KitKat (.157) ROM for your country/operator using Xperifim.
Convert it to FTF using Flashtool. (there are tutorials,search)
2.Flash the FTF you created using Flashtool's Flashmode. Include everything.
3.Root your KitKat (.157) using the forum's tutorials and also install [NUT]'s recovery.
4.Boot into recovery and flash your pre rooted ROM in flashable zip format.
(There are also tutorials on how to create this with Xperifim and PRF programs).
5.Enjoy rooted Lollipop with locked bootloader.

Yep! All done with locked bootloader (or, if you want, unlocked, but you're wasting your time if you're unlocked). So, first you flash the FTF of a KitKat ROM.
Rooting, use Towelroot or something. No idea why, but Towelroot refuses to play with my TWRP (recovery), so I used the old method.

@dazzerfong
One last question cos I just did all the steps but I couldnt reboot into Lollipop after flashing my pre rooted rom zip file.
6. Boot into recovery and clear all data (dalvik, system, data, everything).
7. Flash the zip. DO NOT REBOOT.
8. Shutdown and use Flashtool to flash the .ftf you downloaded.
Check System and Baseband on the 'exclude' column.

On step 8 which FTF you mean exactly? I assume you mean the FTF from which you created
your pre rooted zip initially? In my case the Customized GR version?
N.

You should have downloaded 2 things so far: the zip, and the FTF. That FTF is Lollipop stock: doesn't matter where it's from. Flash that in Flashtool, but remember to check 'System' and 'Baseband' in the 'Exclude' column.

Downgrade to .108 (with flashtool) in order to directly root the phone, whereas with .157, you'll have to flash an older kernel with flashtool in order to get root.
Once rooted, just get yourself a flashable prerooted firmware (zip file) and flash it from the recovery (after a wipe factory reset; wipe data; wipe cache; wipe Davilk Cache and Wipe System).
