About flashing a kernel - Xperia Z5 Q&A, Help & Troubleshooting

Hey there!
I'm a new owner of Z5 and in the past I owned X8,xperia mini,xperia L,and Z3+(with LB),so I'm kind unfamiliar with Z5 rooting,backing up DRM keys,etc.My question is:Flashing a kernel or unlocking the BL can be done only via ADB or can I use Flashtool as well?

I used flashtool to do both.

Any necessary precautions for flashing stock FTF file with Flashtool?

I own an M2 D2303. I've rooted it with Towelroot, so I'm stuck with Jellybean for now and am thinking of upgrading to Lollipop. I rooted mainly to delete bloatware and some stock Sony apps that I thought were useless. I haven't done any modification other than that (e.g. flashing custom ROMs).
I've found an FTF file for update 18.6.A.0.175. My main concern right now is if this will be safe to flash with Flashtool. I've seen some tutorials for flashing that warn me to backup IMEI information before flashing, but those are usually for if people want to flash custom ROMs rather than stock ROMs. So, are there any extra precautions I really have to take (besides backing up the data on my phone...also, would the stock Backup & Restore app suffice?), or will this generally be a safe process?
Flashing you need an unlocked bootloader too not just root,
Make sure you have 50+% battery and the USB connection on your phone and pc is good also do not use your phone or pc especially the USB ports during this period also it's good to get an exact backup of every thing
You do not need unlocked bootloader to use flashtool or be rooted for that matter. Flashtool will work on totally stock devices. totally the wrong information for sonys EMMA software you need unlocked bootloader which is totally different to flashtool

Thank you very much for the response
Just clarifying that I am indeed not talking about Sony's EMMA but Androxyde's Flashtool. So will this be safe for my phone then? Would it really be necessary to still back up IMEI or take any other precautions?
Sorry, I'm just really clueless right now and I'm worried I might do something wrong.

Going from Z to Z5 Compact - downgrade to 4.42?

Evening all,
Just placed an order for the Z5 Compact after my Z has started playing up after 3 years of use,
Basically I had mine rooted a long time ago, and I havnt really touched it since or done any rooting/customization in ages and im drawing a blank..
Basically want to root the Z5 and downgrade to the 4.42 firmware as I have on my Z, as I dislike the 5.51 software the menu options etc looks very tacky for stock Sony layout, and it looks like 6 marshmallow is the same.
Is this feasible or reccomended?
Is there a step by step guide I can follow as I am seriously ****e with computers and all this stuff, I also wanted to learn about and if there are guides on how I can customise the menu etc If I can keep 5.51 or even upgrade to 6.0 and root the device and install a custom theme and change the menu layout etc?
Is this possible at all, I know people have custom software but I havnt a clue on how to go about rooting it let alone customising it...
Any help much appreciated!
There is no 4.4.2 firmware available for z5 series...

I don't think you can customize settings menu in stock roms...

Im planning on rooting from 5.51 found a decent guide with use of command prompt so should be easy I hope! Is there an app/program downloadable after root which will allow me to apply custom themes/ menu layouts.
I can only remember Super SU, and theres an aptoide one I had iirc
hey. no offense but i'd suggest you read and learn a bit more about rooting newer xperia devices before you do any mistake.
its for sure no easy thing if you arent much into this stuff. just to mention one thing: at this moment there is no way to root the z5
with locked bootloader. unlocking your bootloader means, that you most probably lose your warranty and the drm keys. those keys
can be simulated by a workaround, but infact they are gone forever without any chance to restore them.
in the end, rooting the z5 now is a process of unlocking bootloader (via flashtool or adb), flash kernel via adb, flash twrp recovery via adb
and finally install supersu via twrp flash.
these should be enough keywords to google for, and/or getting knowledge here in xda forums. once again, i just can advice
you read all those guides twice....

DRM keys arent really required though are they? are they not restorable/ way to back them up prior, ive googled Z5 compact root and ive got loads of links on search results though
Voiding warranty of new device and god knows what will be with restored fake DRM keys with further updates, and no, there is NO rooting Z5 series with having Bootloader locked for now, i doubt there will ever be a method but hope im wrong. You might want to reconsider Z5 series, replace your Z with Z3 that is easily rootable even with locked BL and is on Marshmallow list.

well, the drm keys are required for e.g. x-reality, camera postprocessing, ps controller support and much more. at the moment the drm restore patch works, but who knows, google or sony could counterpatch this aswell. you can only backup them with root. to get root you need to unlock your bootloader first. unlock bootloader = drm key lost forever. you cant lock your bootloader without original drm keys, and with unlocked bootloader you dont have ota updates and pc companion wont work anymore. means, you always have to update manually with
flashtool.
Really?! Cause with my Z I could link up with pc companion and do a factory reset which wiped out the root and everything on it when it froze up..
What about the main thread on this forum... is there any other reading or threads/guides in relation to this

Best rooting method for Sony Xperia Z3 devices with Bootloader Unlock: No?

I've been scouring the internet for the last couple hours, but I can't find a good rooting method for Z3 devices with bootloader unlocking disabled. My device is running MM 6.0.1, any help would be greatly appreciated.
Me too
+1 for this, I just (soft)bricked my Xperia Z3, and I had to recover it, it came back with the new Boot Loader, and now I can't root it...

One Click Root,how does it work?

Hi all,i am seriously considering rooting my Xperia Z5. I have downloaded and installed One Click Root on my pc. I have checked and it appears to be that rooting my device is possible,my question though is this. Do i have to unlock my bootloader first before rooting with One Click Root,or is it not necessary? Also,what is the situation nowadays with regards the DRM keys etc when unlocking the bootloader if it is essential to do so?

About Sony Xperia phone

Hello, I bought a Sony Xperia L3 I4332 couple of days ago, I wonder if I can root this phone? Since I cannot find any post around XDA about rooting this phone nor other sites. Is it because it is so unpopular?
I have checked the service menu that bootloader is unlockable, does that mean I can unlock bootloader and flash twrp recovery then Magisk? But it seems there are no I4332 twrp recovery in their official website...
Does that mean there is no way to root this phone?

If the bootloader is unlocked and if you can find a copy of your stock firmware to extract a copy of your boot.img, you can use Magisk on PC to patch the boot.img then flash the boot.img to root the device then install the Magisk Manager app on your device.

@Droidriven not to be butting in (your like the sensei of helper-outers) "bootloader is unlockable". which can probably be done from sony website. also i dont know about the L3 l4332 but with my new xperia z3 you need to backup the DRM keys (in the TA folder if i'm not mistaken) before unlocking the bootloader or will lose for ever. they affect camera pic. quality and a few other things.

Ah, I didnt see that at first.
Thanks bro, I''m sure they'll appreciate that.
I didn't look for links or guides, I just narrowed their direction for what to look for. None of the one clicks they tried so far has worked and there is no TWRP for their device, that leaves one option, Magisk patched boot.img, provided that their bootloader is unlocked. I left it to them to establish whether the bootloader is locked/unlockable and where to go from their. I guess I could have said "if your bootloader is unlocked or can be unlocked", but I would have dealt with that if they came back saying it was locked. Then I may have pointed them to an unlock method.
