Downgrade from N to MM - Sony Xperia X Questions & Answers

I tried to flash (using flashtool) the latest MM firmware flashing went good until I turned on the phone.
I got a warning I thing it was (something (I fogot T_T))media has stopped then it started bootlooping. then I flashed back the N firmware found that it didn't erase what was on my phone like it use to do with the Z2;
So, is there any proper way to downgrade?
F5122 - 34.2.A.0.292 (unrooted//LB)

Try different MM FW , or try again same, I got bootloop also on first time, second time it worked and I was able to get DRM keys out. When you flashed did you checked eveything on Wipe Sin table?

When you do a downgrade you need to select everything in WIPE section. You can try leaveing the UserData unticked (hopefully it won't bootloop) but it would be safer to wipe it clean.

I'll keep this in mind next time, thanks.
I know it isn't the appropriate thread, but could you point me to some where that shows how I restore my DRM-Keys (I have backed them up, and I'm not rooted)

Try the dirtycow https://forum.xda-developers.com/crossdevice-dev/sony/universal-dirtycow-based-ta-backup-t3514236
I am using the kernel DRM fix since I nuked my keys first thing I got my phone.

CONFIRMATION OF TA RESTORE!
- Ran tool on Xperia X
- Unlocked bootloader
- Flashed TWRP
- Booted to system
- Got nag about being unsafe due to unlocked bootloader and wanted password. I don't have a pasword?? (nevermind)
- Booted back to TWRP (Also wants a password due to encrypted data - ignored!)
- Pushed TAbackup.img (I renamed it) to /data/local/tmp and verified md5sum is same as original backup.
- Did
Code:
adb shell dd if=/data/local/tmp/TAbackup.img of=/dev/block/bootdevice/by-name/TA
- Rebooted
- Everything back as it was. Original TA restored and DRM keys all active:victory:

Get Sony Mobile Flasher by Androxyde, (latest is 0.9.23.2 built on 19-01-2017 21:50:00) this includes XperiFirm (5.0.0) , check versions, and hopefully you can find some MM versions there, maybe your MM is 34.0. A..., I found some for F5121

downloading and flashing MM
i have checking the Xperifirm , and unfortunately it seems as though Sony have removed it. i did however download and try the MM from (for TA backup): xperiarom.com/sony-xperia-x-f5121-stock-firmware-marshmallow-6-0-1-34-0-1-277/4-0-1-277/
the flash went successful, (apart from one or two warnings or something in Flashtool).BUT, i had the same waring as you, something along the line of "your device is corrupt, and may not function properly. press power button to continue."
after pressing it, it just showed blank screen. i then tired flashing the official firmware (Nougat) which i made using the Xperifirm and Flashtool. the same things happened, i got the warning message and a blank screen. thus i used Sony Companion software repair to restore and i'm back to crappy Nougat.
it would be good if i could have some more information on how you flashed it, or if someone can tell me how to flash properly. Maybe when flashing MM, i didn't check the wipe boxes (like that other guy mentioned in the thread, which i will try once i have free time). And it may be that the Nougat software created, was improper.
any information would be great, thanks!

You need to check the wipes except the TA wipe, I don't have flashtool on my work pc so, I'll update this with a screenshot the things you need to wipe before downgrading to MM;

---

dont forget to add script =-= and you must wipe everything to skip bootloop.

how to downgrade/flash MM (Marshmallow)
Thank you algnerd & max26292 for your guys help! really i appreciate it so much!
Here's what happened, as you guy said to basically select everything in the 'wipe section', i did so. but when it flashes a messages pop's up asking "A FSC script has been found 34.0.fsc. Do you want to use it?" (this is the script algnerd was talking about (which i had no idea at the start)) . i clicked on no, so the process finished (within a short time) i did this twice, and, it basically did nothing, it booted to Nougat as though i didn't touch it.
the 3rd time, when that messaged poped up, i click on yes (obviously after selecting everything in the 'wipe section')........the result.................................................................................... it worked!!!
heres the image of what i selected in Flashtool:
i.imgur.com/8PWMn8Z.png[/IMG]
and the message (the script):
i.imgur.com/EznIw0h.png[/IMG]
so what you need to do it press yes, simple, but time effective.
thanks guys again, it means a lot .

Thanks for your contribution and help, but before i looked at the update you posted, i had already done it. Also, i would like to asks, how comes you've selected everything in the 'Misc TA' (pretty sure i didn't, and i still have the TA, as i checked for warranty).
Thanks again!

Oh right, thanks. I don't think they would have got deleted, as it was official firmware and there was no root.
all i have to do is back up the TA using Backup TA v2 , which i did yesterday, but it kept failing. anyway ill try some time soon and report back.
