S1Boot (Bootloader) Update for Xperia T

Hey,
in latest firmware there is a update to S1Boot (to Version R10A21). I think most users who DONT USE PCC/SEUS will not have the update because Flashtool does not decrypt it correctly.
I packed it up into German Firmware, so if you are interested you can flash this Firmware and then just reflash ANY OTHER Firmware if you dont want to stay on German one. After S1Boot got updated it will stay updated no matter what Firmware you flash afterwards, becasue normally it is not included.
File can be downloaded here from my Firmware collection, directlink to Xperia T folder:
http://ul.to/f/2fvm79
Regards

Thanks for that. Do you know what's changed?
I just checked my version and it s R10A118

This is a small appreciation for all the effort you put in XPERIA devices.

Hi Binary, Can I confirm that I can backup my current stock rom (7.0.A.3.195) using CWM recovery (advanced kernel v4), then flash this for S1 update, then (correct me if I am wrong please!) re-flash kernel and then restore rom via CWM: resulting in being back to my current rom but with S1 Boot update.
Also just check that I should use "Generic DE (S1Boot-Update).ftf" - is this the one you refer to in the OP.?
Thanks for your patience

I updated via PCCompanion and my boot is
R10A118
WHich "latest" version did you get the new boot from? And what is new in it?

Mine is R10A121 and it was flashed with Flashtool.

It is included inside the SEUS files for the 195 Version, but "problem" is that we need to update Flashtool so that it decrypts the File correctly. For now we only added the "alternate" decryption for Loader, now S1Boot seems to be updated too Which is quite good, maybe they add features in future like button for recovery

If you got it from PCC i dont know why you did not get it. Hope you did not understood me wrong. It is NOT implemented yet. I just hope that they WILL update is later on, with this possibility to update the S1Boot it would be possible from technical way

Yes, I understand that, Can you check this firmware. Its the .ftf I made from my PCCompanion update. I dont know where to look to check the boot.
But i do get an update when i connect to pccompanion, allthough it gives me the same FW number, i thought that was strange but maybe its the new boot.

Do your PCC Files are 3 or 4 Files? If your firmware includes the S1Boot update then it should be 4 Files!!
IT CAN BE that the branding firmwares does NOT include the S1Boot update, maybe that is the reason

ok, I only used 3 largest files. The rest were all really small files. I will download again and make a new branded one...that way we will know if branded versions have the new boot.
I will get too it after I have eaten.
EDIT
Weird,
PCCompanion says my current version is 7.0.A.1.303, whilst my phone says I am on 7.0.A.3.195....lets see what happens
EDIT
Looks like i am getting 4 files, 3 downloaded already and still the big one to go....

Hehe.
The S1Boot is a FILE_XXXXXXX file with approx 330kb. But as i said Flashtool cannot decrypt now, it needs manual decryption.

Check my second edit above, i do get that file now.
But guess what, (Like a noob) i forgot i cant use pccompanion anymore because of unlocked bootloader..D'oh
Anyway, any chance of instructions on how to manually decrypt it (Probably nothing simple) or if I send you the files can you incoorporate them into my .ftf so I can flash it?
I canthen also add a branded vodafobe version with the new boot to the ftf list.
Cheers

I need help to find out whish version S1Boot my lt30p has.
I tried to find the postet version numbers in the phone settings, I searched google, I installed SEUS .........
Nothing, I have no idea where you have the version numbers from.

Help with removing jellybean and restoring ICS 4.0.4 on Xperia T 4.0.4

I received my Xperia T (LT30) in December with (what I believe to be) ICS 4.0.4. The other day (5/31/13), I updated my phone to jellybean. I absolutely hate the new update and want to restore my phone to ICS 4.0.4. I want to remove all traces of jellybean from my phone. How do I go about undoing or replacing the jellybean software with ICS 4.0.4? Do I need to root my phone? I'm willing to do whatever is necessary to restore my phone to its prior firmware. I tried using flashtool and firmware to restore my phone. It failed to remove all aspects of jellybean. Please link me to the appropriate links for what I need to restore my phone. Thank you in advance for any advice or links. It's greatly appreciated.

I can't really help you but I'm curious why you hate jelly bean so much?

It didn't remove jeallybean walkman, album, movies, the home screen ui, themes, icons, essntially the entire ui of jellybean was still functioning. I tried a stock ICS FTF and it didn't seem to work. Is there a more current version of ICS 4.0.4 I 'm unaware of? Ideally, I want to completely restore ICS ui and functionality: walkman, album, themes, home screen, etc.

If you want ICS then flashing a stock ICS ftf will do that. It will change everything you want.
Of course you must do it correctly. Make sure you are including the wipe data check box.
Can I ask which ftf you flashed last time? Please provide the download link.
There are a lot of ICS ftf's in the all in one thread, which is the first thread in this section.

I see what you mean. When I use flashtool, I don't have a prompt to check wipe data/ I am using it on a pc using xp if that matters. I am using the latest version of flashtool as well. I tried downloading two ftf files from this list: I tried 7.0.A.3.195 Bell Canada and 9.1.A.0.489 (Bell). The first ftf file was the only file that would transfer and did not install ICS.

7.0.a.3.195 is an ics firmware so if it flashed correctly you would be on ics
9.1.a.0.489 is JB
There should be a box in the top right of flashtool that says wipe data.
which version of flashtool do you have and were did you download it from.

no,
when you drop the ftf into the open window of flashtool you should get a pop up window like the one in the attachment.
In the top right you see a box saying wipe
When you put in a ftf you will get an option in there saying data. Make sure it is checked and you are flashing a ICS ftf. In fact just tick everything in that box and then you will end up with a phone like out of the box
If it doesn't work you are doing something wrong.

I visited the page with ftf files like you suggested, however, I'm not sure which one is the most recent and what I should choose. Does region matter? I am in America if that matters for selecting a file. Could you possibly link me to an appropriate file? Thanks for helping me with everything and I apologize for being such a noob.

I understand what you are saying. The flashtool I was using wasn't giving me the option to check any box. I downloaded an earlier version (0.8 series) and I was able to check a box. However, I am receiving a message saying, "error preparing files" Does this relate to drivers or the ftf being out of date or something else?

You need to download the latest version of flashtool, that's the one I am using in that image.
Then goto the all in one thread and download the same ftf I have in that image.
It's the first ftf in the .195 series of ftf's files and is found by following the links in post 3 of the all in one thread.
Flash that and tell me what flashtool says, because I just flashed that successfully on my T.

The previous attempts I made to flash, I couldn't select any box. The boxes on the right were grayed out. I was using flashtool v0.9.10.1 found on androxyde.github.io. I'm assuming this is the latest flashtool. When I tried an older version of flashtool (0.8.6), I was able to select boxes to wipe data. I'm downloading the file you mentioned now. Could the fact I was using a different file be the reason I couldn't select a box in the 0.9.10.1 flashtool?

Everything should work fine on all FTFS

It looks like you had a dodgy download of the original ftf.
Has it now worked for you?

Hello everyone,
I am new here and I'm having really hard time going around the forums and searching for what I seek and everything is so confusing and I really need someone's help.

I've been looking for threads but there are so many and I don't know which one to take, most talk about some firmware I don't even know what that is but I looked a bit on the internet and found out which is so here are my phone specs:
Sony Xperia Z

Firmware thing: 10.4.B.0.569

Welcome to xda where everyone starts off as a noob
Don't worry we all make mistakes hopefully a moderator will move it in the right place.
Now to answer your questions
a) A firmware is the software installed on your device you have got it right in your specs.
b) The method of rooting depends on the firmware. The firmware you have does not allow easy rooting.
You have two options since your bootloader can be unlocked
1) Backup your ta partition using the backup utility and store it on your computer. Unlock your bootloader and root your device by following the guide posted by cookie ninja in the xperia z
android development section
http://forum.xda-developers.com/showthread.php?t=2656698
[GUIDE][ROOT] How to Root 101 Firmware and regain LB
2) Downgrade your firmware to android 4.2.2 by flashing an FTF file using flashtool (you can find these in the development section as well) and then root using doomlords rooting toolkit. You can then upgrade to even android 4.4 by flashing any of the pre rooted roms from the development section.
All the best.

Hi
Welcome to xda
First you cant root 4.3 only if unlock bootloader and the unlock not hard but better try downgrade to 4.2.2:
Download a software called flashtool from here and install it then after install finish go to the place where you install flashtool and find folder called DRIVERS open it and you will find an exe file open it and select xperia z- flashmode drivers - fastboot drivers then install
Get an FTF file for flashtool like that
After the ftf download finish put the ftf file in "frimware" folder in the place you installed flashtool
Open flashtool then click the lighning icon
Select your downloaded FTF
After few minutes you will see screen appear says WAITING FOR FLASH MODE
Turn off you phone
Hold the volume down button then connect your phone with your pc with usb cable
After few minutes you will see your phone downgradedto 4.2.2
THIS WILL DELETE ALL YOU APPS AND DATA IN YOUR PHONE!!! So better make backup!!.the phone must charged to 80%
Now root your device with kingo root this tool not working on 4.3 that why i said must DOWNGRADE
Install CWM and TWRP recovery here
After finish get a PREROOTED ROM like this
Flash it in recovery
Now we finished
Other notes: the flashtool and FTF can repair your phone if bricked so dont panic if that happened just use the lighting icon:angel:
Hit thanks if helped

Sony smartphones are nearly impossible to hard brick, unless you restored a wrong bootloader TA partition.(the one not from your own device)
The worst case scenario which you can get is total wipeout of every data you have on your phone, so always make a backup of things you need before doing anything.
The things you will need:
1.Basic computer skills
2.Knowing the bootloader of your phone
3.Knowing how to use custom recovery (cwm or twrp)
4.Knowing how to use flashtool
5.Keep a backup of firmware files (ftf) in case anything happen
6.Always check the forum in case the old backup of something of yours won't work in your phone after you updated

Thank you guys, you're all wonderful.

THIS WILL DELETE ALL YOU APPS AND DATA IN YOUR PHONE!!! So better make backup!!.the phone must charged to 80%
Now root your device with kingo root this tool not working on 4.3 that why i said must DOWNGRADE
Install CWM and TWRP recovery here
After finish get a PREROOTED ROM like this
Flash it in recovery
Now we finished
Other notes: the flashtool and FTF can repair your phone if bricked so dont panic if that happened just use the lighting icon:angel:

If you want stock unmodded one you can do it without root. And if you want a rooted with dual recovery you will need root
But I advise you not to use stock kitkat because its lags alot and low battery life
Try those if you want:
Stock no root needed ( flash via flashtool)
Modded and fast with Root and recoveryROOT NEEDED
Thanks!

Hi
Welcome to xda
First you cant root 4.3 only if unlock bootloader and the unlock not hard but better try downgrade to 4.2.2:
Download a software called flashtool from here and install it then after install finish go to the place where you install flashtool and find folder called DRIVERS open it and you will find an exe file open it and select xperia z- flashmode drivers - fastboot drivers then install
Get an FTF file for flashtool like that
After the ftf download finish put the ftf file in "frimware" folder in the place you installed flashtool
Open flashtool then click the lighning icon
Select your downloaded FTF
After few minutes you will see screen appear says WAITING FOR FLASH MODE
Turn off you phone
Hold the volume down button then connect your phone with your pc with usb cable
After few minutes you will see your phone downgradedto 4.2.2
THIS WILL DELETE ALL YOU APPS AND DATA IN YOUR PHONE!!! So better make backup!!.the phone must charged to 80%
Now root your device with kingo root this tool not working on 4.3 that why i said must DOWNGRADE

I made the mistake of unlocking my bootloader without making a backup of my TA, so make sure you don't make the same mistake. Not an issue really unless you REALLY want OTA updates.

P.S: These kernels are same for all Xperia ZR models (C5503 , C5502) because of contain kernel only so you can use them for both C5502 and C5503 models.

Extract kernel.sin and loader.sin from .ftf rom and copy them to a new folder
in flashtool goto Tools/Bundles/Create then select that folder and complete blank textboxes (double click on Device field and select disired device)
in the left listbox select both files (kernel.sin , loader.sin) and move them to the right side then click on Create button to make .ftf kernel in firmware folder which placed in installation directory of flashtool

Thanks for sharing my guide here.
The easier way to create a kernel only FTF is just to open a complete FTF in your archiving software (I use WinRAR) and delete everything except kernel.sin, loader.sin and the META-INF directory. That's it. It takes seconds.

If you updated via OTA, then root is usually kept in that case.

Lots of reasons:
If OTA isn't released yet.
To recover from a brick.
If you've modified /system then OTA will fail.
If your bootloader is unlocked then you cannot update by official methods.
Etc.

flashing this
Hi guys,
It may be another thread I know, but prior I wanna flash this, I am unable to make a proper backup either with CWM (skips backing up android installed apps so the backup is useless) or with TWRP. (it is just not starting the backup to ext_SD)
Can anyone help? those threads are kinda dead

someone pls upload C5502 .230 ftf file

Thanks

I did an OTA update (about 130 mb). after long usage, my battery died and phone powered off.
When I tried to charge it, the phone was bootlooping. It happened for 1 hour and the phone was damn hot.
Luckily, I woke up took the phone out of charger -- otherwise i would have seen a "Xperia ZR Barbecue" the next morning.
The phone did not even get connected in flash mode or fastboot mode because of 0% battery.
I managed to charge the battery a bit and, thank god it got connected in fastboot mode.
I unlocked bootloader and flashed mokee 4.4.4 kernel. Then offline charging worked.
When it was charged enough, I relocked bootloader and flashed .101 JB stock rom, and did a fresh update through PC Companion.
Now, offline charging is fine. For a while I thought I had my phone bricked.
But thank god, I was able to recover it.
So the advice to everyone who did an OTA update is to check offline charging is working fine, before your battery dies.

please anyone upload Xperia ZR_10.5.A.0.230_kernel_only.ftf for 5502 variant
