How can I downgrade from Nougat to Marshmallow on a locked bootloader ? - Sony Xperia XA Ultra Questions & Answers

Hi,
Iam on android 7. but I want to go back to marshmallow and backup DRM keys . I tried manually downloading the marshmallow firmware (or could you point it out to me ) but with flashtool I couldn't do it.
Is there anyother way or sth wrong here ?
thnx.

Bootloader has to be unlocked.

Actually, you can switch to any version as long as it's stock and model stays the same.

are you using patched loader?
You don't use unlocked bootloader. unlocked bootloader has "r8A027" version.
@Blagus... dude where have you been? MSN?
Try with the older version of flasher "FlashTool_0.2.9.1" the 3.0 versios doesn't work with the mini.

display is ON during call (sk17i)

I had flashed my sk17 with LX11.0 but I want to restore my old version of rom (LX10.1). I did a restore of old rom (I had small problems to start recovery but I did flash of some old kernel and after that flash with kernel from 10.1 and recovery started) with restore from recovery.
what is problem? now my proximity and light sensors are not working. during call display is always ON and auto brightnes is not working. what should I do next? :cyclops:
Try wipe cache and dalvik cache. If it doesn't work, wipe /data too.
Gesendet von meinem Xperia Neo V mit Tapatalk 2
from recovery I wiped everything (cache, dalwik and data) and still no proximity and light sensor. after that I try to reflash kernel and the same thing is happening
is there some service menu for cyanogenmod? like sony one service menu just to check are sensors OK
I don't know, I'm not using restore option because I had problems with it in the past.
You can try to enable developer menu in Settings>About Phone>Tap several times on Build Number until you see You are developer and you will see new menu in settings, and try also stock ROM to see if problem persist there.

I/m trying to flash stock ISC because it must be done but flashtool refuses to flash Now I don't know what to do next?
Can you post the error? Maybe it's broken download? Check file size.
Are you in flash mode (green led), or can you actually get in flash mode? Have you selected wipe cache, system, etc.?
If you can get into fastboot try to flash boot.img then flash CM11 and check developer options and test sensors.
Check this tutorial in case you missed something. http://talk.sonymobile.com/t5/Xperi...V-MT11i-2-3-4-update-4-0-2-A-0-62/td-p/134345
P.S. I heard that it is no go with Windows 8.1. If you use that, try with 7 or Linux in VBox.
I had downloaded 3 tft (different stock roms) and everytime I got different error. laptop has windows8 but errors are the same on xp also.
I can flash legacyXperia11 but does it have service menu to test sensors?

I somehow skipped that post, sorry. Try using older version of flashtool, like 0.9.11 see here: https://unrestrict.li/flashtool
If its same result then try this:
1. extract ftf (in linux you will have extract option, in windows I think it will work if you change the extension ftf to zip, then extract)
2. go into the extracted folder with cmd
3. connect your phone to pc in fastboot mode
3. if you set the PATH for fastboot then just do "fastboot flash boot kernel.sin"
- if not, copy kernel.sin to your ./platform-tools folder and use the same command
write if you get an error

how and where I can download ftf for my phone? ((

I don't think this would be a problem, but better check in your section for other stock roms.

Backup TA/DRM using Dirty Cow

A new tool has just been released to backup TA using the Dirty Cow exploit. After that, you should be able to unlock bootloader, flash recovery, flash su and restore TA. Then your device should be rooted with DRM retained.
I don't have a XC so I'm unable to test.

But according to another post, actually it's impossible to keep root after TA is restored. Do you know if it's true?

That's correct. But it's important to have the TA backup for restoring full functionality.
There might be a way to use the previous DRM patches combined with flashing only the TA unit for the device key in order to have full stock functionality with root. Also would need a custom kernel for the latest stock firmware update.

I had the same difficulty finding where to download. lol!
but worked like a charm for me
Add firmware v.34.1.A.1.205 to the list.
http://forum.xda-developers.com/cro...ersal-dirtycow-based-ta-backup-t3514236/page7
(I have no idea why my browser crashes if I point it directly to my post lol)
I just was able to pull a copy of TA from the Customized CE1 (Central Europe) v34.1.A.3.49
When next version (hopefully Nougat) is available I plan to load the known compatible version 34.1.A.1.198 and compare checksums to verify. However, I did get a file with 34.1.A.3.49 which has the November 1st android security updates.
*edit*
After reading it appears that TA changes every boot. However, when the time comes to update software I will revert back to known version with compatibility and then re-pull TA.

Now that we can have a backup image of TA, can we use this tool to repack the kernel and restore DRM functionality?

- Yes, I think we can. As long as the TA unit address for device key has not changed then it should work.
- After some rest when I have my Wits about me I am going to attempt it
Guys,
could someone please tell me step by step, how to restore TA?
EDIT - know, after restoring TA I have a password option - cant get over it? any ideas?
Ok... done
I can confirm, it works - backup and restoring
So...
This is an outline of how I have managed to get root with devicekey back into the TA partition.
NOTE:
- I am only interested in running rooted stock sony firmware so for me this is OK for the moment.
- I am looking into why FIDO_KEYS come back as unprovisioned, everything else seems fine.

Fantastic news! This is major. So in theory we should be able to get more rom availability now?
Android pay gets broken, right?
Will root now

Should see new ROMs eventually surfacing
You're correct Android pay doesn't work with a rooted device
Dump question. I just downloaded the latest firmware using XperiFirm and created a FTF file using FlashTool. But FlashTool always show the following errors.

When creating your FTF, did you include loader.sin ?

In fact, there's no loader.sin in the download folder. I tried to download several firmwares using XperiFirm and they're the same.

I've never tried creating a custom FTF, so I'm not sure. I downloaded the UK version of 34.1.A.3.49 and was able to flash that successfully.
Have you unlocked your bootloader?
Just thinking FTF may be signed by Sony?
Maybe with a locked bootloader you can't flash custom FTF?

I'm really worried, not able to restore stock rom backup

I took a nandroid back up about a year ago and today when I restored it my phone gets stuck on the purple boot screen. How do I restore the stock rom?
Bootloader Unlocked
No DRM Keys
Nandroid Backup from twrp
I left it for about 2 hours straight....
Any help is appreciated

If your previous rom was android 7 or 8 then you should flash stock rom first with flashtools then you can restore your backup
Don't forget to check all boxes of wipe section in flashtools

I have a Sony z2 d6502 (India)
My previous stock rom was marshmallow 6.0.1
My phone is a d6502 but after flashing a custom rom (Resurrection Remix) Nougat, CPU-Z and Build.prop states that my variant is a d6503.Is that possible?
Also, I cannot flash any .ftf files on flashtool because of the bundle error.
The Sony FLASHTOOL log is given below:

Also, flashtool is not able to detect my phone even though ADB and Unknown Sources are on , I also installed all the required drivers.
Is it because of the Custom Rom or the variant of my phone?
Just a reminder, my phones variant changed from d6502 to d6503 after resurrection remix......
I don't have a TA partition.....

Which version of flashtools are you using???
Use older versions like 0.9.18.x or 0.9.19.x
They may solve the problem

Issue 1:
When I flash it, it gives error-root bundle is not valid
Is it a .ftf issue?
Issue 2:
Flashtool Log:
Checking Root Access
Root access denied
I already have magisk installed on my Sony z2.

Issue 1: maybe it is from ftf file but i don't think so
As i said use older versions of flashtools
Issue 2: that will not make any problem and it is not important

I am using 0.9.18.6 (flashtool Version).. Should I install another FTF file if so, which variant do I choose (d6502 or d6503) or should I just try both?
Just wondering I still cant restore TWRP backup with system and boot backed up (It just gets stuck on the purple boot screen the waves one)

choose d6502 and yes change FTF file
the problem with TWRP backup is because of the nought version of RR that you flashed and now you want to back to stock based rom so you should flash stock rom with flashtools and wipe everything

Is there any way to root marshmallow 6.0.1 on sony z2

But, for some reason I can't load twrp using adb.
Adb says it is successful but for some reason pressing power down or power up does not boot into twrp.
