Needing help with TWRP + root.... walkthroughs telling me different things. - Xperia Z3 Q&A, Help & Troubleshooting

Hey hi hello. Rather than screwing up my phone, I'd love some help from people who know more about this device than I do. I want my device to be rooted, all my phones I've owned have been rooted and it's not optional for me. I've been reading a lot of walkthroughs, but I seem to be getting mixed instructions. Can someone help clarify what I need to be doing?
My device is a Sony Xperia Z3 D6603, 6.0.1 software version 1282-2729_23.5.A.1.291. I unlocked the bootloader last night. I have ADB installed, Sony flashtool by Androxyde, finding the TWRP image file is easy since it's on every walkthrough, I have almost all the files needed, except the kernel, and that's what I'm needing help with. I'm following a walkthrough on droidviews (I can't post a link ) and I'm lost on what I'm supposed to flash. What it says: "The process described here is valid for Xperia Z3 variants – D6603, D6653, D6633, D6646 and D6643.
In case you are running the latest Marshmallow firmware, that is the .291 firmware, you will need to flash the kernel from .575 kernel. Download the correct .575 kernel for your device." Obviously my device is the 291 version, so I'm supposed to flash the .575 version.......????? But later in the instructions, it says "This time flash the .291 kernel for your device also available for download above. Make sure you rename the .zip at the end to .ftf". I just really want to be certain I don't end up using a file not meant for my device. ---before anyone yells at me, I *have* been trying to look for the answers of this myself, but I would prefer to second-guess everything so I don't end up with a very expensive paperweight.
Edit- I've been seeing a looooot of people saying they get stuck in bootloop or soft brick after getting TWRP installed, are these just people who didn't follow instructions correctly or is this simply a very common issue to run into when dealing with this particular phone?

I really need help bringing back to stock.

My phone has been bricked for months. I am trying this guide on xda: http://forum.xda-developers.com/showthread.php?t=2542219
So far all the stock firmware seems to not work. I am 90% sure my phone is US Retail but I am not sure if it is XT1032, XT1045, Falcon, Peregine, or whatever it is.... So I am confused as to which files I am supposesd to flash to return to stock; and where they are located.
I currently have access to the bootloader and have TWRP custom recovery installed but I don't know how to install the stock firmware. If anyone could help me understand which model my phone is / why my flashing isn't working, it would be more helpful than they could imagine... :good:
Other threads I made on this simply redirected me to that thread, but I can't find any help or related topics :/
Additional info: I strongly believe that the model number is the issue as I followed countless other guides on how to install Cyanogen Mod and a couple other roms since I got this phone brand new. None of the roms flashed properly, none of the recoveries worked, until now. All I have is a recovery left and a bricked phone...( + access to the bootloader of course)
For your Model number Check Ur Mobile Bill/Box...
Could you also look it up with the imei #? In case a box is not available

Thanks for the help, but I found the problem.
Opened the back of the phone to check the model number and it was XT1045 like I thought, so I had the right stock images. Problem was I did not have the Motorola drivers for mfastboot installed correctly. I used a guide to install them universally on mac and my phone is back up and running!

[Q] [D2303/D2305] PC won't recognize my device after attempted root

Good day all I have a question regarding my new device which I attempted to root. I have searched these forums and can't find anyone with the same problem as mine. Running 4.4.4.
For reference, I was following this guide: http: //tinyurl.com/o6v3hqf
Everything was going swimmingly. I followed the steps in the guide exactly up to and including typing "fastboot reboot". Once I did this, my PC would no longer recognise the device that was plugged in. In addition, the Xperia M2 will not boot, the Sony logo will appear and then the screen will intermittently flash. I can boot it into recovery mode, just fine, but there is no file on my Xperia to boot from.
The next step in the guide says to install SuperSU from an SD card which I am confident I can achieve, but I am concerned that my PC won't be able to recognise my device if the root is successful (therefore I wouldn't be able to transfer over music etc).
Will my PC be able to recognise the device once the root is successful? Should there be additional steps I need to take?
Sorry if my questions seem Noob-ish this is my first smartphone.
Thank you for reading
.
Open the sim tray.
There will be a small hole. Jam a thin pen or a pin or paper click into it.
Wait a few seconds and make sure screen is off. Go into a dark room or somin. If it's not hold the pin in until it is.
Upon boot spam the down vol. as fast as you can.
It'll send you into CWM.
Then you should be able to follow into the rest.
Also using the UK and the International .ftf i was unable to root (i could but after it was bricked)
So i had to use the vietnam rom.
ALSO it was (here comes the hate m8)
You didn't read it properly and was partially your own fault. It clearly states it for 4.3.X running 18.0.A.1.30 – v01. By running a boot.img or kernel based on "completely wrong" generations you have bricked it your self.
I suggest you redo this but following this guide here.
http://forum.xda-developers.com/xperia-m2/help/tut-flashing-ftf-4-nbz-t2970145
Flash the vietnam .ftf also find out what model your phone is D2303 or D2305.
Wrong .ftf will waste a good 30mins of downloading and render your phone useless until further flashing a new rom or ftf.
Then flash the boot.img from here : http://forum.xda-developers.com/xpe...2303-cwm-based-recovery-6-0-4-6-root-t2884503
The 2 posts explains it very well in the posts it selves. But don't be afraid to ask questions.
Hope I helped
Thank you for the advice. I agree I started following a guide without doing the necessary research. 100% my own fault. I will read the guide you posted and report back!
I can't find this Vietnam ftf anywhere.
My model is D2303. I have followed the above guide but flashed to Central Europe 4.4.2. I am still looking for a Vietnam .ftf file. I have found links for Malaysia and Russia, but no Vietnam yet.
I used the internal/journalists jb4.3 ftf top one in list on flashtool. Has the 4.4.2 and 4.4.4 updates waiting once booted up. I'm in UK and it works 4g n data just fine ,I Rooted 4.3 with towelroot apk (one çlick) then updated over the air twice each time checking root with root checker. Then force root with flashtool then installed SuperSU but don't update binarys in SuperSU till you have forced root and updated to 4.4.4 this was my first time ever rooting a phone too.
It helps to do your home work though i did two months reading up on here and the net it helped loads
sent from my b/l 2303 rooted on 4.4

[Q] Help finding the right firmware version

Hello !
I posted yesterday about upgrading to lollipop on an unlocked bootloader.
I thought i got it, but need additional help.
1. Im using Xperifirm to find 23.1.A.1.28, but i can only find versions that has diffrent brand names. I have Halebop carrier, and I can only find Telenor and 3. What differences is there based on branding?
Can you just use the Central Europe one without problem or what is that ?
2. What do R2C mean after the version name. 23.1.A.1.28/R2C ?
3. Do i need to manually root it, if i cant find any prerooted versions, and if so how do I do it? Can i preroot it myself before flashing?
4. Custom recovery: Do you flash it on the same time as the android firmware? or do you do it separately? do I need it first to be able to fastboot?
Sorry for the noob questions, im new to flashing. Have done it before, but then i knew exactly what i was doing from the beginning, now im om a used phone, and have no idea what has been done. I know it has unlocked bootloader, but cant get Super Su to work to root.
PLEASE HELP ME !
BTW I have looked for answers in the forums, but I cant get the whole picture out of it... And some of the guides were outdated etc.
(I have Flashtool 0.9.18.2 installed)
Discalimer: I am quite new at this but here what's i understand:
1. For same device, i.e. D6653 you can sue any ROM, difference customizations just include special apps from that country and carrier. I am using customized HK ROM and debloated it.
2. I don't really know but different regions have different codes like that so I think it just for different regions.
3. Yes, first thing you want to do it, search giefroot, that's the tool you root with, use a FTF to flash back to 23.0.A.2.93 and root and install "nut dual recovery". You need to flash back because that's the only one you can root on Z3. After, this never flash FTF unless it's completely unavoidable for some reason. Always flash zips through recovery. Search "PRF Creator", it will help you make prereooted firmware zips.
4. I answered this in 3.

To experts, how can I Update after root?

Hi xda developers, I'm a new z3 user (D6633) running lollipop 5.1.1 , and I want to root my z3 to use titanium Backup,
1) I'm afraid that if I root my z3, I won't be able to update to marshmallow when it arrives, I also read somewhere that I still can update but will lose drm (I don't know what that is )
2) is there a way to unroot, to install the official update ?
Please explain in details and provide links if you could, cus I'm totally new on Sony
Any advice is appreciated
Im sure there will be a pre-rooted stock ROM for dl as soon after M. hits. Depends if one need to flash other things as well like firmware etc. but these things are included in the same FTF. I have gone through a few Android versions and things usually works out fine in a short matter of time.
If you absolutely want to go full stock, just flash a stock FTF from http://forum.xda-developers.com/z3/general/ftf-stock-firmwares-xperia-z3-models-t2886061
Using Flashtool.

XPERIA Z3v Unrooting Issues

So I recently rooted my XPERIA Z3v device, and I have decided to unroot it (don't bother trying to convince me to keep the root, I am far beyond your rhetorical questions) and I rooted with the mobile version of kingoapp.com root. When I attempt to unroot my device, neither the computer software nor the app itself are unable to unroot the device. Honestly, I regret ever rooting, and being the rookie I am, I just want to unroot my device so I can go about normal life.
Can someone please help me? I am on the edge of **** right now.
Flash a stock FTF using flashtool or force a software repair using PCCompanion

Can you provide links for FTF and such? Sorry for the pestering, it's late at night and I just want to go to bed.
PC Companion refuses to acknowledge that the Z3v exists, Sony lacks support for it.
http://www.flashtool.net/index.php
You can download the FTF using flashtool as well.
I am pretty sure PCCompanion provides support for the Z3v
Trust me, the XPERIA Z3v lacks any support from Sony. It is basically the basterd child of the Sony smartphone division. Pc Companion won't work for this, I have tried many times.
As for the FTF, I don't see any D6708 model firmwares there, is my feeble newbie mind missing something?
On another note again, I will be willing to keep the root access, it's just that I attempt to replace the Kinguser SU app, and superSU can't seem to update it's binary to do so. Any help there?

what firmware version are you looking for? LL or LP
Original KK firmware here: http://firmwaremobile.com/index.php/xperiadownload/file/262-z3-v
I can't find the LP leaked firmware. I believe you can download it using xperifirm and create the ftf using the flash tool.
I am looking for firmware 23.0.E.1.44. I found a supposed compatible firmware on Sony's website, but the boot unlocking and flashing seems to be a bit out of my range when it comes to understanding. (Kitkat 4.4.4)

can't unlock the bootloader on the z3v so don't worry about that. You'll have to use the flashtool to flash the KK firmware I linked above then take the OTA to .44
