Downgrade 2353 to .112 Firmware and Root. - Sony Xperia M4 Aqua

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.

Alright then. I'll download the firmware from xperia firm instead maybe that'll give me the correct one.
Do I set it to "unpack automatically" or no?

[Q] Neo V Stuck on Sony Logo

OK, I tried installing this rom http://forum.xda-developers.com/showthread.php?t=1737862, but I skipped step 0, as I had flashed my phone with that kernel a couple days ago when I rooted my phone, the rest of the steps I did all of them, all the cleans and wipes, but smth obviously went wrong, and my phone won't boot staying at the sony logo. I saw some other threads here with the same problem, but I couldn't find a solution. If anyone has a solution that will work at 100%, I'd appreciate it. My phone is not recognized by PC Companion so I Can't do anything there. I can't boot into cwm either, I can only use flashtool to flash my phone with a kernel, and I can't use fastboot mode as my device is not recognized in flashboot either.
use SEUS and repair your phone. (when it ask you have the latest version, just install anyways)
Read.. read.. read.. same posts.. same questions.. but different people..
Xda is just not to post your questions.. its there to learn.. bro search.. there is answer to this to..

Do a full wipe n reinstall the rom
Bro
Gl
Okay. So it is possible to Flash a ftf file o your phone. And Fastboot mode is used to Flash kernels, While Flashmode is used to flash ftf files.
Thing to do is,
1.Get a ftf file ( better if prerooted )
2. Flash ftf to you phone using flashtool. (flashmode)
3. Then Flash Pureness With all steps followed strictly.
Or
1. Get ftf which is not pre rooted.
2. Flash ftf on you phone.
3. Root your phone again and install CWM. or Flash Custom kernel which comes with CWM using Flashtool (fastboot mode) and flash superuser.zip via CWM to root. ....// Both methods are to root you phone.
4. Install Pureness following each instructions.
Dont worry!
Even I faced the same problem as yours and I was flashing the same ROM. What I did was in CWM I wiped and formatted everything as per the steps and when I was doing install .zip file from SD card it was giving me error something like "BAD" Error, the problem was that I didnt copy the ROM .zip file properly to my memory card.
So do one think first download the official 4.0.4. ICS ".ftf" file of your device from here-
http://forum.xda-developers.com/showthread.php?t=1678690
(As per your device 4.1.b.0.431 OR 4.1.B.0.587) it must be around 200 - 300mb.
Then copy that .ftf file in C:\Flashtool\firmwares (Make sure there is no other file present in "firmwares" folder, if there then delete it.)
(Hope you have installed Flashtool. If not then download & install it from here-
http://androxyde.github.com/index.html?1357230558000)
Then open "Flashtool", press "Flash" button and select "Flashmode" press "Ok" then again press "Ok"
wait for few seconds while its preparing.
Then a new window will Open and follow the Instructions like- unplug device, power off, press and hold back button and connect it to PC
This will install the stock ICS on your phone and will go ahead of that sony logo where you are stuck. :good:
Thats It. Your Done!!

Thanks man, that's what I was looking for, the stock ICS for my phone. Did that, re rooted my phone and this time things went fine, I managed to install pureness, even though I didn't do it from cwm directly, but from a program called x-parts (which seems to install cwm) since cwm itself would say no recovery for your phone or something, once again thanks. Also, that method with SEUS works as well, so thanks to that other guy, too. And to the guy saying search, I searched, read my OP, and I tried different stuff before asking here for like 4-5 hours, but I just panicked into thinking I ruined my phone so I came and started my own thread, since that's what the guy in the 'welcome noob' video said, but I guess people aren't allowed even to ask around here.

Flash 4.1.B.0.587.ftf using flashtool
or
1.Factory reset in cwm
2.wipe cache partition
3.wipe dalvik cache
4.Format /system (in mounts and storage)
5.Format /data
6.Format /cache
7.Install XXX.zip (XXX=the rom name)
8.Install patch for your phone model (if there are)
9.Reboot
U seemed to take things wrongly bro.. see whatever solutions people have provided u is from xda threads only right? Soo that means if u read u will get it.. its not that we dont want to help.. the point is the help is already available.. its just that u have to search.. thats all.. bcz mny people have this doubt..
evry person rooting his phone n doing this stuff first tym has this doubt.. n helps are already provided.. dont misunderstand people and blame that u are not allowed to ask questions.. chill and understand..

Already quite a few guides and one of the most noob friendly guides are available in this Neo forum and we are lucky to have it
Why not make use of their time and effort?rather than duplicating a post and cluttering up the forum!
The threads /guides are noob friendly
Creating a new thread without searching /without checking for a thread having similar title is not appreciated here!
I get your point and also know you didn't ask the question but just wrote this to clarify things incase you weren't aware!

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?

New bootloader for open devices (now with real recovery)

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

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).

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!

Does anyone have a method for rooting the M4 Aqua on .167 firmware?

Does anyone know how to root the .167 firmware of the M4 Aqua? I don`t want to downgrade due to the improvements made on this firmware, I have the E2303 model of the phone
With unlocked bootloader, you can simply flash twrp and then the supersu zip. With locked bootloader i dont know.

Yeah man. Unfortunately you do gotta downgrade first if your bootloader is locked. Otherwise just do what the other guy said.
Here's what you do if you've got locked bootloader.
Get the full source and files here: http://forum.xda-developers.com/m4-aqua/development/bl-locked-twrp-touch-recovery-bl-locked-t3257430
1. Downgrade
2. Flash root through adb
3. Flash recovery through adb
4. Build pre-rooted upgrade zip
5. Flash with recovery
6. Now you're on .167 with root and bootloader locked.

Hi! I really need some help...
Would you mind being a bit specific about a couple of those steps? I'm sorry but i'm a bit noob, and im a little confused about all of these ways and step to root your phone. How do i downgrade and is 26.1.A.1.128 the right version for the E2203? Are the steps you just referred explained with more detail anywhere? I'm sorry for all these questions but this is being an harder process than i was expecting...
Thanks

Sure thing friend.
I'm going to assume you meant 2303 correct? If it is indeed a 2203 like you say, you don't have an xperia m4 aqua. You have an xperia e3 and you'll have to go get support in another thread.
ADB, Fastboot, Drivers
First you'll need to make sure you have ADB, Fastboot and Drivers to interact with your android device.
The easiest way is to follow this guide to get all of those: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
Downgrade Firmware
1. First get yourself firmware version 26.1.A.1.128 for your variation. You can probably find your firmware at this link: http://forum.xda-developers.com/m4-aqua/general/stock-xperia-m4-aqua-xperia-m4-aqua-dual-t3141061 (Get the 26.1.A.1.128 version or any firmware that has xx.x.x.1.xxx! The x's can be anything but the 1 is important)
2. Once you have that, you'll need to make sure you have a program called FlashTool.
Download: http://www.flashtool.net/downloads.php
Open it and click the lightning bolt in the top left and make sure flashmode is selected and click okay. Then click the 3 dot's button in the top right of the window that pops up and browse to the folder that your FTF file is located. Then choose the ftf file. check both options under wipe. If you see any .ta files in the firmware content area, make sure you exclude them. Then Press OK.
3. Unplug your phone (if it's not already) and turn it off. Now, plug the one side of the cord into the computer with the other side not connected to your phone yet. Then hold down the volume down button while plugging in the other end of the cord. sometimes you get a popup asking about a script file. just click okay and let it proceed.
4. once this whole bit is done. You have downgraded your firmware.
Installing Root on downgraded firmware
1. Download this rootkit file:
https://www.dropbox.com/s/edse0h6b02odzn1/rootkitXperia_E23xx.zip?dl=0

3. make sure USB debugging is turned on in your phone settings. Go to settings. Tap about phone a whole bunch of times till it says you're a developer. Then go back and just above about phone should be another section called something like development. click that and scroll down and find a checkbox that says something like enable usb debugging. Click it and you're ready to root.
4. Now run install.bat in the rootkit folder. If your phone asks you a question about permissions, just click allow.
5. your phone should restart and you should now see the SuperSu app in your app drawer. If you don't see it, try installing the root again.
Installing Custom Recovery on any firmware with root
1. Download this recovery install file:
https://www.dropbox.com/s/yomdwq3p2le9hvi/M4Aqua-lockedTWRP-0.1-installer.zip?dl=0

Hi
I've flashed E2303_26.1.A.2.167_CE.ftf and everything works fine but I still got the BL locked. if I flash other ftf I get no network signal on my phone, I just get signal with this ftf.
if I follow your instructions I will have .128 unlocked but I will still not have signal on my phone, right?
if I flash .167 after unlock the 128 will I get the .167 unlocked? if anything goes wrong and flash .167 again will everything works fine?
many thanks, and great detailed explanation on how to unlock our phone.

If I`ve understood correctly, it will remain unlocked:
1. Downgrade
2. Flash root through adb
3. Flash recovery through adb
4. Build pre-rooted upgrade zip
5. Flash with recovery
6. Now you're on .167 with root and bootloader locked.

Guess I could have mentioned the first boot could take awhile.
I should also mention that because the bootloader is still locked that it is nearly, if not actually completely, impossible to brick your device. There is almost always a way back to a functional device.
I'm glad this all worked for you though.
cmstew said:
Yeah man. Unfortunately you do gotta downgrade first if your bootloader is locked. Otherwise just do what the other guy said.
Here's what you do if you've got locked bootloader.
Get the full source and files here: http://forum.xda-developers.com/m4-aqua/development/bl-locked-twrp-touch-recovery-bl-locked-t3257430

Hey can you help me with something? I'm trying to downgrade to .112 but when ever i try to flash it, it gives me an error on boot delivery, it says that there are some files missing. I already tried with several ftfs, and other flashtool version including latest one. The only ftf that i'm able to flash is stock 26.1.A.2.167 adn i got it from xperifirm. I already tried to flash everything except for bootboundle, but it will still get in a boot loop.
If you have flashed xperia m4, can you please tell me what flashtool version you used, and what ftf compilance? I have E2306.

Thank you, thank you all. I finally did it.
just some remarks that can help other guys with same issue:
1. I need to use the newest version of Flashtool. without the final patch 26.1.A.1.128 was always rebooting the phone.
2. After the last step (Installing the latest version of android while keeping root) I had version 167, network signal was working fine but mobile data doesn't. I went to Settings -> Wireless & Networks -> ... More and clicked "Internet Settings". mobile data started working and no further issues found.
3. Finally, in the end I got .167 rooted but no able to enter the custom recovery. As my device was rooted I just repeated the step "Installing Custom Recovery on any firmware with root" and now everything was as expected.
many thanks

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

Edit: If I Re-Flash with different regional firmware, will it brick?
anybody please provide link for official N firmware..
Thanks in advance
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!
