New bootloader for open devices (now with real recovery) - Sony Xperia Z Ultra

Hi all,
I have a great news
http://developer.sonymobile.com/201...for-a-range-of-unlocked-xperia-devices-video/
Bootloader is compatible with open devices roms and also enables real recovery (Volume Down + Power)
to flash recovery partition on device you have to
fastboot flash recovery recovery.img
Happy Cooking
J
PS.
in case latest software does not appear just press "all Services"
flash latest software available and on top new loader

Up it?
Can someone drop this new bootloader img on a filesharer? I'm in a boot loop and Emma won't let me in (even with the supplied configuration INI file).
Thanks!

Here you go... in FTF and loader.sin format.
Good Luck.

Another way to flash?
Thanks for that! As I said, I can't get Emma to work. In fact, even after reinstalling and pasting the INI file in the Program Files directly again, it still keeps me on the login prompt. So, is there another tool I can use to flash this FTF or SIN file? I have fastboot working, but no ADB.
Appreciated!

Final thanks
I found out about the distinction between Androxyde's FlashTool and Sony's "flashtool" Emma. I hadn't before known that the former existed, and Sony's use of the term "flashtool" confused me. Thank you for the file. Didn't seem to help (see my post here: http://forum.xda-developers.com/showpost.php?p=60964546&postcount=2), but thank you anyway!
Ta!

my c6802 isn't supported by emma.........can't i flash the new bootloader in my device????

[Q] [Need Help][Urgent] Problem with Phone and Busybox/xRecovery

Okay, I have a big problem with my phone, I decided to redo the operating system to a new version/ROM because the one i was using on it before several issues where coming up with it, 1: I Couldn't connect to other providers even though i had phone unlocked. 2: Some default programs where having problems starting.
So When doing a kernel upgrade my phone did not respond kept staying for 2 hours on the "SE" logo, and would not budge, so i decided to remake it, after about 4 hours i was able to get a OS on it, but this OS was older and out of date, when trying to go back to xRecovery it did not want to come up, i downloaded a Reboot to Recovery APK, which informed me that My "xRecovery" was not installed, which is weird because it was installed before.
I been trying to get the Default root method to install xRecovery which every time i ran the "Flash tools" program, it would not allow me to install xRecovery.
If anyone can contact me on skype "mradziwilko" to help me out, or post here ill be here checking on forum every min.
Thanks
Anyone would love some help?

Hi buddy, Have you tried to use ftf file like zahdi5h, http://forum.xda-developers.com/showthread.php?t=2212260 to update?
You have to have unlocked boot loader and you can drag and drop the ftf into flash tool. Make sure you tick no final verification in flashtool or you will get error.
If that don't work then I suggest starting over with fresh 2.3.3.
Go back to stock using Sony Ericsson Update Service (seus) Use google or search threads for program.
Then just re-do, unlock boot loader and install recovery again with flashtool.
Hopefully zahdi5h ftf file will get you out of trouble.

I downloaded this FTF File, when opening it with the latest Flash Tool, it does not Recognize it.
Is their a possability you can link me another FTF, i know CM9 worked, but because i dont have a boot loader i need a ftf to be flashed, i tried with the IMG file, but the flashtool.exe keeps saying <Waiting for Device> and does nothing.
Also to add more info :
My Phone I thought was originaly a Xperia X10a, which it bios it says its a Xperia X10i.

Hi mate is your boot loader unlocked? If not then unlock it with flashtool. Try Version 0.9.10.1 of flashtool. Work's for me.
Download from http://androxyde.github.io/index.html?1373179542000
And you can also drag and drop the FTF file into flash-tool. FTF contains Kernel and rom., tick the no final verification box on bottom right.

Installed XZDualRecovery, wiped everything via TWRP, Now stuck at sony logo

Title says it all...almost.
Was already rooted on 4.4.2.
I did a TA backup.
Then I followed the instructions located here to get custom XZDualRecovery .
All worked great!
Was able to boot into TWRP and Philz successfully.
Performed a full backup in TWRP onto a thumb drive over OTG cable.
Then wiped everything via TWRP in preparation for a CM11 rom.
Rebooted before trying to flash CM11.
Now can only boot to sony logo, fastboot, and "System Recovery" mode. (the mode that has 'continue power up' 'safe mode' 'factory reset' and 'power down'
I, like all the other noobs who didn't RTFM, missed the ''Be sure to flash XZ/ZL/TabZ/Z1/ZU-lockeddualrecovery[VERSION]-BETA.flashable.zip from http://nut.xperia-files.com after installing the ROM and before you reboot, this way you will not lose recovery!'' part of the XZDualrecovery post. =(
Now, my questions is, what if you DID forget to flash dual recovery after wiping?
What happens now?
I am thinking, is there a way to flash XZ/ZL/TabZ/Z1/ZU-lockeddualrecovery[VERSION]-BETA.flashable.zip via fastboot?
If so, how?
Thanks for your time and be gentle.
after 8 days with no help, I read 10 different threads on 10 different issues that KIND of pertained to my problem.
Wrote all Pertinent info down on a sheet of paper over the course of 4 days of searching.
And then started piecing together a solution.
Here's what I did to fix my issue for anyone who has the same problem.
1. Download xperifirm and select correct firmware for device
2. used Flashtool to convert above downloaded firmware to FTF
3 put tablet into flashmode
4. flash FTF file via flashtool
5. viola!
Thanks..I think.

Had a similar situation, sorry I didn't see this earlier to help out. No need to convert firmware, you can use Flashtool to download your carriers latest FTF

Thanks for the reply!
I do have a question about the ''you can use flashtol to download your carriers latest ftf" part.
are you referring to being able to download the firmware from the flashtool site here?
Or can you actually do it directly from the flashtool program?
My 2 problems are, 1. I do not see ANY firmware for my SGP561 (verizon) tablet on the website
and 2. I do not see any options for firmware download in the flashtool program
EDIT: Found it! Flashtool program > Devices > Check Updates
Is there a way to flash downgrade your firmware to a lower build number so you can officially unlock through Sony's dev site?

[GUIDE] (C6833) (Maybe Others?) New Bootloader + Recovery

Installing the new Sony Bootloader and Recovery
THIS IS FOR ALREADY UNLOCKED DEVICES!
DO NOT TRY THIS ON A GPE!​Since a lot of people seem to have problems keeping their recovery when flashing Lollipop-ROMs i decided to put up this little guide...
You can also Skip this whole guide, by just flashing the newest stock-FW at least once!
First off, as already said, this is for already unlocked devices. You can use this Guide until "Install Custom ROM", except the rooting part, for rooting use this, if you haven't already!
Don't do it if you don't atleast somewhat know what you are doing.
I am not responsible for bricked devices, or whatever you might end up with.
So, lets get started.
1. Download Sonys FlashTool "EMMA" and install it: http://developer.sonymobile.com/downloads/tool/flash-tool-for-xperia-devices/
In the .zip file from the FlashTool you'll find a File "customization.ini"
Copy this file to the installation directory of EMMA, usually "C:\Program Files (x86)\Sony Mobile\Emma"
If you don't copy that file, Emma will ask you for a login, don't create an account there, you will NEVER get any activation-email!
2. Open EMMA and boot your Phone into FlashMode (Power off your device -> Press and hold volume DOWN -> while pressing volume DOWN insert USB-Cable)
3. Emma should now recognize your device, but you have to select it manually tough. Select your EXACT model number. Again, I am not responsible for any bricked devices or whatever you end up with!
Now select the "(Open Devices) TA update" and click "Apply Service"
It should take a few seconds and should then display SUCCESS.
You can now close Emma
4. If you haven't already download FastBoot and Drivers: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
(Run as Administrator!)
5. Download the newest version of twrp and put it somewhere:
New Inoffcial twrp-3.0.0 build by me: http://forum.xda-developers.com/xperia-z-ultra/development/togari-twrp-recovery-3-0-0-t3314440
Old official versions: https://twrp.me/devices/sonyxperiazultra.html
6. Finally boot up you Phone in FastBoot-mode (Power off -> press and hold volume UP -> while pressing wolume UP insert USB-Cable
Your LED should now light up blue
Shift+Rightklick in the Folder where you have put TWRP recovery, and select "Open Commandprompt here"
Now write "fastboot flash recovery FILENAME_OF_TWRP_FILE"
You can now unplug your USB-Cable and boot into recovery and continue from there.
Your recovery will be permanent, meaning you won't loose it or replace with any other recovery that might come with your ROM.
I hope this was somewhat helpfull

You can try, just select your modelnumber in emma
If the "Open Devices (TA Update)" show up, you're fine. If not just don't do anything.
But do not try this on a GPE!

tried, but no luck. thanks.
It's really weird, I used emma, and installed their latest ta update. Now I can get into fastboot mode, all commands execute successfully, but the recovery never takes. The vol down + Power doesn't work, nor does 'adb reboot recovery'. Am I missing a step somewhere? This isn't my first android device, but from where I sit, it seems like something is up with my xzu.
If I try and install the 14.4* update through emma, it goes through the whole process, completes "successfully", then boots into 14.5. Something is clearly not working here.
The TA update only unlocks the ability to boot to recovery, it doesn't install one. And no, flashing official TWRP to recovery partition doesn't work, it must be compiled again to work on normal recovery partition and not in FOTAKernel, where it must be flashed to work.
Regards

I´m on CM 11 M12 (looking forward to 12) + the new sony bootloader without any custom Kernel stuff.
Sadly, you are right. It´s not done with downloading twrp-2.8.5.0-togari.img and fastboot flash recovery yourfile.img.
The last offical TWRP release for Xperia Z Ultra is from february 2015, any chance they release an updated version for the new Sony bootloader?

Is there any (wish for TWRP) recovery for togari, which use the new bootoader?
FYI:
My device is a brazilian c6843.
Emma recognizes the device automatically and indicates with an exclamation point that there is no services available to the unit.
In the case someone doesn't know, it's basically the c6833 with DTV 1seg. It's totally compatible with c6833 firmware, losing TV, of course.
You sir are the real hero! Thank you!
I have a xzu running cm12.1, and I have 2 quick questions for those with more knowledge than me
Is it possible to flash the new bootloder using the open source FlashTool?
If I have to use emma, is it possible to just apply the open device ta update *without* installing stock firmware first?

You can totally do that, BUT, the newest stock firmware also has some firmware updates regarding nfc, also having the newest stock rom flashed at least once will be kind of a requirement to get everything properly working on marshmallow roms.
So I would say flash the newest stock rom at least once!

I followed your advice, but it seems I am missing a few clues.
My sirius was on cm12.1. I backedup and flashed D6543_23.4.A.1.232_1281-5466_R6C.ftf with flashtool on linux. I tried to use emma (several times) afterwards to check for any TA updates, but all I got was "no services matched this device" or something like that. Google tells me I am not the only one with this issue with emma
Then I used fastboot to install twrp 3 from twrp.me to recovery partition, but I could not access twrp.
I fastbooted recovery again with twrp 2.8.7, and this time I could enter twrp and reflashed CM.
Now I can access twrp using the button combinations while booting, but rebooting to recovery from CM leads to a bootloop. Has anyone experienced this as well?
So it seems I am still missing a few clues to using the recovery partition. Is any build of twrp supposed to work on both FOTAkernel and recovery partitions?
Is there a TWRP 3 build that works from 'coldboot to recovery' and 'cm reboot to recovery' with the new bootloader? Any pointers?

Well, booting to recovery on separate partition from os, requires the rom to have a patch... the "new" mm-roms (when they finally hit aka. are ready to be shared in public) will have that, so no worry, just wait.
why it said my phone have no available service, i am on c6833

Downgrade 2353 to .112 Firmware and Root.

Hello guys!
I am very new to this sony stuff and I decided to root my phone. I have the e2353 model and I planned to use flash tool to flash the .112 firmware I got from xperia blog. But, flash tool detects the downloaded tft as a tft for the xperia M2 2303 model. Should I go ahead and flash this one? One more thing, When I attempt to flash it, flash tool complains that it has finished processing "loader.sin" with errors then says I should install the correct flashtool drivers for my device. I believe that one can be fixed by just simply installing the drivers included in flashtool's "drivers" folder, yes?
Thank you!

Try searching Xperifirms for the files. Better be safe - flashing a wrong tft files means a bricked device... Also :
"Instructions
I found this guide very helpful and thus you can refer it here :
http://forum.xda-developers.com/showthread.php?t=928343
SOME CONSIDERATIONS :
1.Make sure you choose the FTF file for your device or you can risk bricking your phone forever.
At the moment, there are no FTF files so you will need to be patient.
2. Make sure all drivers are properly installed
3. To boot into flashmode/fastboot, you will need to turn off device.Hold volume up OR volume down and then connect your device while holding the volume key.
Volume up would take you to flashmode while volume down would take you to fastboot mode. Remember, you will need fastboot/flashtool drivers before you can flash anything.
here is another guide for you just as reference.

issues rooting Xperia XA Ultra F3211 Nougat (7.0)

Hi there
I am struggeling with the root process of my XA Ultra F3211 (running 7.0 Nougat) and I just don't find a solution for my problem on the internet.
I hope y'all can help me with this one..
I read several guides how I can manage to root my phone, I think the basic points are the following:
- USB debugging has to be enabled - there's no problem with that one
- bootloader has to be unlocked (if possible) - it is possible for my phone and I did it
- USB drivers have to be installed - i installed the whole Android Studio including the SDK manager where I could choose to install the Google USB drivers
- you need the flashtool (I installed v. 0.9.23.1), a boot.img, a custom recovery.img and magisk or SuperSU
1. then you should flash only the boot_delivery.xml from the Marshmallow firmware in flash mode (I guess you need to do that because it's not possible to root Nougat without this step)
2. afterwards you should flash the boot.img and recovery.img in fastboot mode using a command line and the fastboot commands (fastboot flash boot boot.img / fastboot flash recovery recovery.img)
3. after you have done this the custom recovery should be installed and you should be able to boot into it to wipe the phone and flash magisk / SuperSU
That's the road so far.
I've tried these steps but I am not able to boot my Xperia into recovery mode. I think the problem is the boot_delivery.xml because when I tried to flash it from a 36.0.A.2.109 (Marshmallow) firmware (it's named customized_UK, I'm from Germany but I did not find a MM FW for Germany) the flashtool gave me the following information:
- Parsing boot delivery
- No flash script found.
- Flash script is mandatory. Closing session
- Ending flash session
- Flashing finished
I found those lines in some posts on the internet but I did not find any information. Someone said that he copied the default.fsc from the C:\Users\YourUser\.flashTool\devices\F31XX to the F32XX directory and renamed it into device and firmware versions. I did not find any default.fsc in this directory so I copied the one from the F33XX directory and named it "F3211_36.0.A.2.109.fsc" and guess what? I started flashtool and the fsc file was deleted. Even if I created it again while the flashtool was already running the tool never asked me if it should use a script - it just tries to flash and gives me the lines I listed above.
I'm not sure if this is the problem, but flash mode seems to work (the Xperia's LED is glowing green) - so does fastboot mode (blue LED) and for both: no unknown devices in Windows' devicemanager.
Maybe it did already work and I just can't manage to boot into recovery but I tried everything (vol down + powerbutton, vol up + powerbutton, powerbutton and repeatedly vol down or vol up when the screen turns on, hold all three buttons at once) - I think vol down + powerbutton should work, the phone vibrates and shows the Sony logo, I let off the buttons, the screen turns off again, then the Sony logo appears again and the phone starts normally into Android.
Does anyone have an idea what I can try to get my Xperia rooted?
Am I wrong in any point?
Looking forward to reading your answeres and thanks in advance
@dionarap, if the guide explains that you have to use Flashtool v0.9.23.2 why are you using v0.9.23.1 ?? Update it, download firmwares again from included Xperifirm, use FSC script when asked and all should be fine

Thank you very much for your fast response
Well, you got me there. I forgot to exchange the x10flasher.jar in the flashtool directory.. *facepalm*
I'll try it when I'm at home again - but I have one more question before I'll do that.
When I start XperiFirm (through flashtool) and choose my device (F3211) the only entry for the Market "Germany" is build nr. 36.1.A.1.86 / R1B - according to another post that's also Nougat.
So which firmware do I need and could I choose a firmware for any Market if I only need to flash the boot_delivery.xml? Or can I use a downloaded ftf-file from another source? I found the 36.0.A.2.109 firmware (which seems to be MM 6.0.1) but it's named "...Customized_UK" and the at the download source the region was entitled "Russia" so I'm not really sure if I should use this ftf-file. I can find a firmware 36.0.A.2.109 / R6A for the Market "Costa Rica" in the XperiFirm - should I rather use this one?
Is it basically possible to tell which Android version a build nr. like 36.1.A.1.86 (Nougat) or 36.0.A.2.109 (MM) has or did I get something wrong?
Edit: I tried the "Costa Rica" firmware and it worked for me - rooting done
Thanks for the assistance!

You are on the right way
Yes you can know the Android version with the firmware build numbers.
For the MM firmware, you can download it with any customization/build it's not important we only need boot_delivery.xml
For the N firmware, you have to use the same as flashed in the device. You can download (and flash) it with an other customization too, the differences are small like LTE/4G icon, some apps are different like Spotify, Gameloft, AVG and the APN settings can be missing for your network provider (easy to add).
I don't recommend to download firmwares from the web because you will not have the FSC file who is very important to avoid hard brick. There is a way to manually add it but I will not explain how to do because I really dislike this way.
Thanks again! rooting is complete I think I just was too blind to notice this mistake after googling, reading and trying different things for several hours.. Again thanks for the assistance

Hi there
How far did you go? Did you already flash recovery and did you already enter it once? What was your last step before you got the sony screen? I'm not sure if reflashing can harm your phone but I think you should use a firmware downloaded via XperiFirm (it's integrated in Flash Tool). To get a Nougat firmware for Xperia XA Ultra look for build nr. 36.1.A.0.182.
Hope this helps - good luck mate!
