Xperia Z3- How Do I Downgrade to KitKat 23.0.A.2.98 So I can Get Root? - Xperia Z3 Compact Q&A, Help & Troubleshooting

Could not downgrade to get root
Hi all,
I'm a very big fan of this community, but only to read and learn. But now I need your help...
History: rooted my phone few months ago in the way told in this post. Everything went well, but last week my screen broke. Sony fixed it but also put latest software on it... and removed root.
Today I tried to downgrade to KitKat 23.0.A.2.98 again (stil had the FTF) to get root again, so I can put back my Nandroid backup. I didn't manage to get it working... after restarting after flashing when the blue screen appears before you are asked to unlock your SIM... my phone makes a pitching noise for 10 seconds and then reboots again. The process repeats itself again and again.
Fortunately I can flash the latest firmware back and my phone works again... thank God because a thought for a moment I soft bricked my phone.
Anyone a solution to get root? I'm now on LP 5.1.1
thnx!!!!
ciao

How did you downgrade? The normal way... means: using flashtool (latest version) and which settings did you use for flashing? ...and did you try downloading a different version and flashing it?

Hi Tom, yes I did it the normal way... latest flashtool and settings the same as before, so I checked no boxes. After that didnýtwork I tried something different, so checked all wipe options. I also tried a different version and flashed that via the normal way. That didn't work either... the only flash that worked so far was 23.4.A.0.546 / R7C. But that's way to new to get root via downgrading

So the flashing process did always work without problems? But the result is always as you described?
And if it's only about root... did you try Kingroot? Afaik it is supposed to work on almost all versions.
Another thing: I don't remember all options by heart (and can't check them atm)... but maybe try some of the provided options.

It's more that when I reboot after having flashed back to earlier FW my phone bootloops... so I don't even get a chance to continue and root. Very annoying!
My next move is to find another old stock FTF (probably not a Dutch one) and will try to flash that one with different boxes checked.

When I'm back home I can check for the one that I used (quite recently) when relocking BL and rooting etc. If I don't find the source anymore, I can maybe upload it for you.

Ok... so this was the version that I used... to downgrade and root:
D5803_23.0.A.2.93_Generic_GLOBAL_1286-9917.ftf
try this link maybe:
https://mega.nz/#!f5pXVAIZ!nWmaFU9d5ux6FOUI6Kdv3GK8RObswoZzxRwpQVEvpxo

There's an easy way to get Root on 5.1.1 without having to downgrade back to kitkat
- Unlock your bootloader on Sony's Website
- Search for a custom kernel here that is for 5.1.1 ( e.g. Androplus, etc )
- Boot into fastboot mode in Flashtool and flash the kernel
- You now get recovery because the kernel comes with a custom recovery
- Flash SuperSu's latest Zip file to get root
- Enjoy

Maybe be careful when recommending that without mentioning, that he would loose his DRM keys in that process... so I would always add the comment, that he should have a backup before unlocking. Or at least mention the loss of the DRM keys as a warning.

Oops I almost forgot, but I always have my DRM Keys backed up

But it did not matter in the end anyway

[Q] Phone bricked? Process inside.

Ok so I decided after using this thing stock for ages I was going to try CM11. Spent all day reading and trying to figure this out.
Used Krabappel guide to downgrade to .534 via flashtools. SUCCESSFUL.
Unlocked Bootloader via Sony official. SUCCESSFUL.
Backed up TA via guide. SUCCESSFUL.
Rooted via Root_with_Restore_by_Bin4ry_v33. SUCCESSFUL.
Then moved onto trying to find/install a recovery so I could flash the CM11 rom. Now where things seem to have gone awry...
Flashed advanced stock kernel v4 by krabappel2548 in accordance to this thread: http://forum.xda-developers.com/showthread.php?t=2439298
Via this command: fastboot flash boot adv-stock-v4.img
Claimed it ran through successfully. Tried to adb reboot recovery, no devices found.
Now device will not turn on. Holding down the power button resulted in a single buzz, no screen activity. Volume up+power gave the three vibrations for reset, no screen activity. Currently red blinking light when plugged in via usb.
Not sure where to go from here. Currently sitting and charging while blinking away.
Thanks for looking. This was so much easier on nexus devices lol!
Hello friend, i suppose you should try booting into fastboot mode via holding volume UP and connecting USB, see if flashtool recognizes it.
If it does, then we need to find you a pure stock kernel to install and later a recovery.
Also, what android firmware you had before flashing kernel?

Beautiful, flashtools does recognize it: blue LED and "device connected in fastboot mode"
I believe I was on 14.1.G.1.534 since I needed to downgrade to that in the first step, and I don't think any steps I took afterwards changed it AFAIK.

If you felt a vibration you are not bricked thankfully. Try flashing another ftf in flash tool and start over.
edit: oops you beat me to posting before I hit post.
Looking at my steps taken, did I mess something up? I'm not sure what I did wrong and would like to not repeat this mistake.
I found out what you did wrong.
You needed to have 14.2.A.1.136 fw to install the kernel. Read carefully what it says here.

If you messed up with the kernel, you might have to install a new one.
But firstly try what angryGTS said before me. Reflash .534 and see what happens, then i will happily help you get to a solid firmware and install CM11
Also, you backed up TA after unlcoking BL or before, and how you backed it up (recovery or other tool? )? (It's important that you have backed up BEFORE unlocking BL :/ )

That's just great news.
Your camera should not be working since you have unlocked BL and firmware version .534 . Root it using Kingo Root or such one click root programs.
And then install recovery from here .
-Use this to go to rooted 4.3 . thanks to NUT (at this point your camera should start working again)
-Use this to go to rooted 4.4 version .681 , thank NUT again (you can stay here if you want Z2 camera mods and DoomKernel and other stuff availiable to fw up to .681 )
And optional go to latest .757 KitKat using this thank NUT again , but you won't be able to do much here.
Also when you are at .681 , you might want to flash to CM11 there , check here and thank FXP team.
Have fun. And remember to read instructions carefully .

OK I got the recovery installed fine.
Is it safe to go from .534 to 1.136? Looks like NUT removed the 4.3 0.290 files that you linked today.
Do I need to be using his kernel/de-odexing at all?
thx

You basically just need to be rooted, on any FW with recovery and you can flash it

Well, according to Xperia Update Checker by Macmol, your device is Movistar Colombia and here is the problem, because it's still with 9.1.A.1.140 firmware.

Sure you can
9.2.A.1.210 is better because it's the last.
If you flash with Flashtool you can't root, because there's not a direct method yet.
The only way to keep root, is flashing a pre-rooted 9.2.A.1.210 via recovery.
FTF files for Flashtool are in General section, instead ZIP files for recovery are in Development section.
Good luck

1) Install recovery
Download here: http://www.androidfilehost.com/?fid=23269279319202175
Take your phone, go to settings, developer options, turn on and select USB debugging.
Connect the phone to PC now.
Unpack CWM4XperiaT_v8i_JB.zip
Run install.bat/install.sh
Follow the instructions, remember that your device is V, keep an eye on the display of the phone and give root permission when asked.
After the end of the process, enter into recovery like this: turn off the phone and turn on.
Immediately, try one of this combination:
Press repeatedly (not holding) power button until the phone vibrates
OR
Tap repeatedly the screen
2) Once you're in recovery, make a BACKUP.
So if something will go wrong or simply if you want to go back to 4.1.2 because you don't like 4.3, you will be able to return to the present situation just resuming this backup.
3) Install .210
Remember that you will lose all your data and apps. Instead what is inside internal memory and SD card is SAFE (backup included)
Download and install Flashtool
Download THIS and move it into the directory C:/Flashtool/firmwares
Download .210 zip file HERE and copy it into the internal memory of your phone.
Turn off and go into recovery.
Make a wipe data/factory reset.
Then install zip from sd card, choose zip from sd card, select .210 zip file.
When it's done, select POWER OFF (be careful, DO NOT select reboot).
Open Flashtool, click on the lightning symbol ("flash device"), select "Flashmode" and click on "OK"
Now select LT25_9.2.A.1.210_1268-6904_FIX4.3 and click on "Flash"
Wait for a window to pop up
Now take your phone, push the volume-down button, keep pushing and connect to your PC
Once the flashing process has started, release the volume rocker as soon as possible
NEVER disconnect the USB cable until it's finished!!!
Turn on and enjoy! :good:

1) If you want to keep root you must download LT25i.210_nor_deodex_root_philz_v1.zip that I linked above, since it's already rooted.
2) When you flash zip via recovery you don't touch the old kernel. You flash only the new system. After that, you need to flash the new kernel, so you need Flashtool with LT25_9.2.A.1.210_1268-6904_FIX4.3
3) When you switch from an Android version to another, a full wipe is always recommended. A partial wiping could give strange behaviours.
Therefore it's better a fresh installation of the app and then (when possible) a resume of the backup offered by the app: for example I'm quite sure that Whatsapp has a backup option within its settings. Use THAT option if possible with any app. Right?

Wipe cache is already included into factory reset.
Wipe dalvik cache is not mandatory in this case... do it if you want
Anyway all wipes will be repeated by Flashtool, so don't worry about that.
In Flashtool you have to change NOTHING, since yours is a brand new installation. Just flash.
works with lock bootloader ?

LOL... I'm not so noob.
Yes my method is for locked bootloader.
Unlocked bootloaders have to flash another kind of kernel.
The kernel you're installing is the original one.
And no, you can't unlock an Xperia V through Flashtool. It's impossible at the moment.
The only way to unlock is getting a code through Sony site!!!
This rule is valid for all 2012 devices onwards.
You're too anxious

Unlocking is mandatory for new Xperia that can't be rooted directly, because they are too new and they've been released with 4.3 or 4.4
We don't have this problem because we have 4.1.2 that is easy rootable, so we can install recovery and do everything we want

This is for locked. Stop asking. Don't worry.
I did this million times with locked bootloader.
During the process does your phone ask for root permission? Do you tap on yes?

[Q] Root, and recovery on Kitkat .757

Hi all,
I have a c6903 Z1 currently on Kitkat 4.4.2 (after an OTA update I really wish I'd never done) and I want to root it so I can install the SD card permission fix - can't put up with not being able to write to external SD, it's infuriating. If I can fix that, I can probably put up with KitKat.
If I'm still not happy with that then I want to go back to 4.3
Having read a lot, and I mean pages, and pages, about it, and having to downgrade, I've picked up that I would have to use NUT's .534 ftf to avoid losing the IMEI, and then I was going to root with vRoot.
Does anyone know, does that install Superuser or will I need the Superuser zip too?
At that point I want to then install recovery, so I'm looking at NUT's Z1 Locked Dual Recovery.
I rekon that should all be fine.
To get it back on KitKat I should then put the 757 zip on my SD card and flash in recovery, reboot and flash the stripped ftf with Flashtool, along with the recovery again.
If I still don't like it, I could then just repeat the above, but with the .136 zip and stripped ftf.
Am I thinking right here?
The only thing that's a bit worrying is that, for example, the .136 update thread says to come from .290.
Is this so, do I have to install that first, or can I go straight from the newly rooted .534 directly?
Sorry if this has been answered before, but my eyes are killing me staring at this screen now.
The only other thing I'm thinking is to just not root, and simply flash a Jelly Bean full ftf.
I'd rather have root and recovery though.
Thanks,
Mick.
wow, you didn't read much
DO NOT USE VROOT, IT SEND YOUR IMEI TO AN IP ADDRESS IN CHINA.
To get root on 757, just follow the step sin my signature
No need to use any root methods or unlock the bootloader
3 steps, 5 minutes work max.... a bit longer if you have slow download speeds

Just wasn't looking in the right places, so it seems.There is an awful lot of info on here though, and one link leads to another, however very informative reading.
Thank you so much for your help, don't mean to be a pain, and I do appreciate it.
All you guys do an amazing job.
Will it make any difference if I use the Z1 locked recovery instead of the XZ one, or should I just use the XZ anyway? Does it matter?

download the file for the Z1 from [NUT]s page since that one is for this phone.
the XZ is for the xperia Z and that is a different phone. It is always advisable to download and flash things that are deigned/made for the phone you have, not another phone....
u don't need to install the 290 version first, get nut's 534 stock, then install dualrecovery and go straight with the 136 one.
Check nut's instructions or use this youtube video which is foolprove.

I am not sure if we got our wires crossed before.
the XZDR installer will install dual recovery on your phone from PC
the Z1 flashable file will upgrade to the latest version from recovery itself, but will only work on a Z1.

Oh, right, well, I've downloaded this installer -> Z1-lockeddualrecovery2.7.123-BETA from NUT's site.
I'll flash NUT's .534 ftf with flashtool first, then I'll run the installer from my lappy, and that should root and install the recovery.
I have also downloaded the Z1-lockeddualrecovery2.7.123-BETA.flashable - I assume that's what I need to flash after flashing another ROM if it doesn't include it's own recovery.
I have noticed some ROMS have earlier version recoveries, like .80, built in. Can I still flash the .123 on to of those with no issues? I have read there had been some issues with flashing over older recoveries.
Has anyone figured out why the IMEI was being lost? Was it due to the baseband
I've already got the drivers installed, in fact I successfully flashed back to .136 just to try it (last flashing I did was on my Arc S, so been a while) last night as I just couldn't be bothered with KitKat anymore.
Thanks again,
Mick.

If the installation was successfully then it doesn't matter. The older one working well. In the case you want flash the newets one then you have to wipe your phone with a stock FTF.

kind of, but don't worry, you will have your IMEI back after upgrade again.
I can open a topic for this question, but i'll just ask it here to prevent extra spam etc hehe.
If i get to a 757 rooted firmware using these methods, and i want to go to a non rooted firmware like 769 if it comes out. Will that be just a matter of reflasing the tft that belongs to that firmware using flashtool, or do i have to make more steps?
Thanks for answering!

When 769 will be out then NUT will have Pre-Rooted FTF like the 757, so you will have just to repeat the same steps. If you will want go to 769 Stock then 1 step will be required, flash it via Flashtool.
I want to remind you also that we do not predict future so we don't know what Google will do to they future Firmwares so the steps can be less or more, nobody know it.
Just one more thing, sorry to be a pain.
I'm happy with the process, flash NUT's. 534 ftf, then run the recovery installer to get root and recovery.
I don't want to install a custom rom right now.
I either want to end up on 4.3 with root and recovery, or 4.4.2, root, recovery, and the SD card fix.
If I use the zip and stripped ftf files from NUT's download page, I'll still retain root access, is that right?
Then just reflash the recovery zip before rebooting, and job done?
I've had no issues with the stock .136 firmware I've currently downgraded to other than the NFC icon not appearing when active. Something I've gathered can be fixed by editing the build.prop, but doesn't bother me anyway.

I'll assume your phone hasn't been messed with. i.e. The bootloader is locked, and it's not rooted, and that you're using a Windows PC.
If you have changed your phone, let us know.
Make sure you have USB debugging turned on in your Developer Options, and Unknown sources in the Security settings.
To enable Developer Options in your settings, go to Settings, About phone, and keep taping Build number until it says 'You are now a Developer'
You'll need to download the latest version of Flashtool from here --> http://www.flashtool.net/download.php
You'll need to install the drivers for your phone too. The driver installer is in the flashtool/drivers folder.

Bootloader is unlocked I have flashed firmware before but not rooted.
My main reason for wanting to root was to get rid of apps I dont want like the google ones.
Do you already have a recovery installed?
If not, installing the Z1 locked dual recovery will also root your phone. Just make sure USB debugging is turned on, plug your phone in normally, and click install.
As per my post above, I've just flashed NUT's .534 ftf, booted up, then ran the recovery installer, and it's working well.
I can boot into recovery, and have already done a nandroid backup. Best to do that before anything else.
All I have to do now is choose a rom and flash it.
In all honesty, if your bootloader is unlocked, I'd probably flash a custom kernel which has recovery and root already. I don't know much about flashing with unlocked bootloaders as I don't intend to unlock mine just yet.
Did you backup your TA partition before unlocking?

I'm not really sure if you mean "flash" by "root" but yes. You can flash any stock ROM as long as your bootloader is locked. Your data will be wiped and you will no longer have root access.
It will be like a brand new phone. :silly:
Go check some guides on how to flash back to stock with flashtool.
Use Google for NSIS error fix. I think there are alot of guides aswell.

You need to use XperiaFirm software to download the official ROM and convert it into ftf.

[SOLVED] Generic .108 FTF... Which one??? Please help a noob out

Hi all,
I havnt flashed a device since the first android ROMS for the HTC HD2, so that gives you an idea of how rusty I am, so please bare with me. I've been reading and searching for hours and my eyes feel like they are bleeding so I'm typing this plea for help whle I atill have some vision.
I ve got a c6903 z1 running the latest 5.1.1 update. stock kernel etc, locked bootloader.
I was on 5.02 rooted and now want to root 5.1.1
After lots of reading I realise that I need to downgrade to 4.4.4 kitkat, then root then install dual recovery, then installl a pre rooted 5.1.1... FIRSTLY - Does this sound right? are these the right steps to root 5.1.1?
Secondly, It took me a while finding Generic .108 ftf files but now I've found a few (through the ftf 'mega thread') and dont know which one I need... the options are:
C6903_14.4.A.0.108_1276-7939_R3C Generic MY.ftf 1060174KB
C6903_14.4.A.0.108_Customized KR.ftf 948416KB

C6903_14.4.A.0.108_Generic_SG_1276-7937_R3C.ftf 1048335KB
Will any of these work considering I'm not staying on 4.4.4?
I assumed I could safely use the 'UK' file from the above list but then got paranoid I might brick my z1 by flashing a Ukranian ROM lol.
I've now got 'the fear' and am afraid I might **** this whole process up and brick my device.
which reminds me, one last thing... Ive downloaded the official SONY Flashtool (ver. 0.9.19.8).. is this the right tool for the job? I seem to remember reading that the official flashtool only works on unlocked bootloaders, but I've read so much im confused as hell at this point.
Sorry for the long post,
Any help would be greatly appreciated.
Correct. There is no direct root for 5.1.1 currently. You could also downgrade to 5.0.2 instead, it doesn't really make a difference between that and 4.4.
It doesn't really matter what your interim ROM is as long as you do a clean flash when updating to 5.1.1 again.
Flashtool is the correct tool to be using. It has a utility called XperiFirm built it. You can use that to get any FTF that's publically available so that you don't have to depend on FTF threads.
The only way to have rooted 5.1.1 is with a pre-rooted zip, so you'll have to use PRFCreator to create that zip if there isn't one already posted for the specific variant you want to use.

Hey there! Welcome to the Z1 community
All you have to do is make sure you flash the ftf specific to your device. As long as it says C6903 in the ftf, you're good to go. all these locations are just country specific customizations with some apps and stuff. I'd say you can just flash the SG ftf for a mostly bloat free system.
In addition, you can't use the SONY flashtool (EMMA) unless you have an unlocked bootloader. I'd recommend you use flashtool (just google it) which lets you flash on both lock and unlocked bootloaders. Once you flash KK, use one of the rooting programs (Turn on USB debugging, and connect it to your computer, run the application and go through the steps. Let me know if you need help on what method of root to use.)
Once rooted, you should have a recovery, which should let you flash a prerooted zip easily.
If you have an unlocked bootloader, just flash any custom kernel through fastboot, boot into its recovery By pressing vol up or down at boot logo) and flash the zip.
Final tip is, make sure you have the prerooted zip on your sd card before you flash a custom kernel, as not all can mount to the PC from the reovery and flashing an incompatible kernel (such as a 4.4.4 kernel on a 5.0 rom) won't let you boot into the ROM.
Feel free to ask if you have any doubts, come across any issues, or need any help at all.
SOURCE: I flashed a customized TW ftf on a Singapore bought C6902 which I'm using in India with no issues at all.

The only way to have rooted 5.1.1 is with a pre-rooted zip, so you'll have to use PRFCreator to create that zip if there isn't one already posted for the specific variant you want to use.

Thanks for the quick reply mate. Sounds good, I might just go to 5.02 then as rooting that was fairly painless.
Ive already found a pre-rooted zip for stock 5.1.1 so I think I'm good to go on that one. Almost ready to dive in... thanks for clearing that up.

Hey there! Welcome to the Z1 community
All you have to do is make sure you flash the ftf specific to your device. As long as it says C6903 in the ftf, you're good to go. all these locations are just country specific customizations with some apps and stuff. I'd say you can just flash the SG ftf for a mostly bloat free system.
In addition, you can't use the SONY flashtool (EMMA) unless you have an unlocked bootloader. I'd recommend you use flashtool (just google it) which lets you flash on both lock and unlocked bootloaders. Once you flash KK, use one of the rooting programs (Turn on USB debugging, and connect it to your computer, run the application and go through the steps. Let me know if you need help on what method of root to use.)
Once rooted, you should have a recovery, which should let you flash a prerooted zip easily.
If you have an unlocked bootloader, just flash any custom kernel through fastboot, boot into its recovery By pressing vol up or down at boot logo) and flash the zip.
Final tip is, make sure you have the prerooted zip on your sd card before you flash a custom kernel, as not all can mount to the PC from the reovery and flashing an incompatible kernel (such as a 4.4.4 kernel on a 5.0 rom) won't let you boot into the ROM.
Feel free to ask if you have any doubts, come across any issues, or need any help at all.
SOURCE: I flashed a customized TW ftf on a Singapore bought C6902 which I'm using in India with no issues at all.

Thanks for the in depth reply mate much appreciated. And thanks for the welcome, cheers
Ive got a locked bootloader so I'll check out that unnoficial flashtool, thanks.
Now here is where my confusion and lack of knowledge becomes another problem... You say that after rooting kitkat (using something like 'easy root tool'?) I "should have a recovery, which should let you flash a prerooted zip easily.".......
I was under the impression that after rooting kitkat I would have to install
'XZ Dual Recovery' to let me flash the pre-root zip.
Do I not have to install XZ dual recovery?
Thanks again for all your help... just trying to clear up the details before I start the whole process.
Cheers mate.

Some root kits will install a custom recovery for you, but it's so easy to just install XZDR, that's what I always do. XZDR will actually give you multiple recoveries to choose from (but TWRP is generally considered the best), but it also has some nice addition features like RIC killer (which allows you to have full root vs partial root).
I should also clarify my previous statement - XperiFirm is great for getting *new* firmware.. but you will either need to back up copies of old firmware for future use, or seek them out in threads if you need them later.

ahhh, now that makes sense (re: some root solutions including a recovery), thank you for clearing that up.
One final thing (before I dive in and at least get KK installed+rooted)...
If I have to start reading one more subject I think my head will explode lol so If you could just clear up one thing about RIC Killer....
I want full root, not partial - do I have to mess with RIC Killer or can I leave it alone?
On the guide I am trying to follow; someone said they ended up 'half rooted' - would that be because of RIC killer or user error when creating the pre-rooted zip?
just dont want to go through all this and end up only being half rooted haha, cheers.
edit: ok so after checking flashtool it seems I already have the right one (NOT SONY)... I have version 0.9.19.7 But there are two warnings (pasted below) on the flashtool thread.
Does the first warning simply mean 'Use the latest version'??
I have no clue about the second warning...do i just uncheck the uption regarding simlock.ta IF it is in the list of options when I flash kitkat? I have no clue if my ftf file includes simlock.ta.
Both warnings mention bricks and hard bricks so I'm taking them pretty seriously haha.
Any advice on these warnings would be great, thanks for your patience.
"WARNING : Since Xperia Z, sony added a new set of files I called bootbundle. Those files can be bundled from 0.9.13 and can be flashed from 0.9.13 only. To all those flashing devices from Z edition to all after Z, it is highly advised to use 0.9.13 and to be sure FTF you flash contain the bootbundle set. I've been reported of hard bricks because of missing such set of files from bundles.
I WANT TO GET YOUR ATTENTION ABOUT THE LATEST BRANCH 0.9.19. Without FSC, the tool will by default include simlock.ta if this file is present in the FTF. The result will be a bricked phone
As a workaround, until I release a patch, please please tick the exlude simlock.ta if you see it in the list.
0.9.19.6 fixes the simlock.ta issue. This file is by default excluded. Then it will not be flashed until you explicitely untick the exlcude simlock box. Do it at your own risk."

Even if you don't have a RIC killer installed, most root stuff will work fine. On the Z1, the RIC will prevent you from doing specific things, most importantly mounting /system as writable, which is necessary for certain type of advanced modifications.
However, if you install XZDR, you'll get the custom recovery + the RIC killer. I would just do that.

Correct, the warning is to just make sure you use a version later than 0.9.13; you're fine to use 0.9.19.7. It will tell you that .8 is out, but the change is not important to you. You don't need to do anything special regarding simlock.ta.
If you have an external SD card, copy everything you want to flash onto the phone before starting (5.1.1 prerooted, SuperSU, XZDR), so it's already there when you need it.

THANKS.
So As long as I install XZDR I will have RIC killer and that will ensure a full root? thats great, cheers..
Thanks for clearing up the flashtool warnings too, very much appreciated.
As for your final tip about the SD card... do you mean copy everything to the SD card? or the phone? I'm ASSuming you mean the SD card as the phone memory will get wiped during flasshing if I clear everything? no?
Sorry mate I'm having a total brain-fart after everything Ive read, my comprehension skills are at an all time low lol. Tired.
Thanks again for all ya help mate, I'm just about ready to get this crap done... and then once Ive finished I know I'll be thinking 'wtf was all the panicking about? lol.

Make sure you flash SuperSU and XZDR at the same time. If you do not, it will not work correctly (still only partial root). If you make your own pre-root ZIP, you can roll them into it and do it in one fell swoop.
Yeah. External SD card = not the phone. If you do a clean flash (which you should), you will be wiping the phone storage.

You're the man, man...THANKS. :highfive:
I'll check the pre-root zip I found and if it doesnt have Supersu included I'll make my own and include XZDR too - I like the idea of having things 'slipstreamed' into one flash - thanks for the tip.
Thanks a lot for all your help in calming all my little worries about this process,,, very much appreciated.
I'll do the whole lot tomorrow and report back... thanks again.
Suggestion - since you are re-learning and your goal at the moment is to have a rooted 5.1.1, I suggest you download and install Flashtool for windows. Go to http://www.flashtool.net/index.php. Now in Flashtool, your need to install the appropriate drivers for your device/s. Instructions searching (I'm doing my lunch while typing reply - lol). Then use XperiFirm which is integrated in Flashtool. It has its own icon, just click it so you can download a 5.0.2 FTF for yor region. Install that 5.0.2 FTF on your phone using Flashtool (Flash it Baby! Flash it!) Then you can root 5.0.2 with ease using Kingroot. Replace Kingroot with SuperSU. Then install NUT's Dual recovery. Then you can download any of the pre-rooted 5.1.1 FTFs XDA peeps are putting up under the General section and boom. You are now on 5.1.1. with root.

cheers mate, I appreciate all the help I can get lol.
I decided to go with 5.0.2 instead of kitkat, but when I click on the .270 firmware links in xperifirm I get an error which says:
"Incomplete Firmware.
The following files are missing on the server:
fsp.zip.
Proceed with caution"
I clicked on the latest 5.1.1 firmwares and none of them give this error... so does the error simply mean that .270 is not the latest version? I couldnt find the answer in google. Are thes firmwares without fsp.zip safe to flash?
Thanks again.
edit: hmmm looks like i'll have to flash 4.4 instead.
When I try to download a .270 (5.0.2) firmware in xperifirm; it stops downloading after a few seconds and says a reuired file is missing
If I try to download one of the .368 firmwares it downloads ok
edit 2: F*ck my life... Not enough space on C: for unpacked ftf file (Small c partition on SSD) ... so unless there is a way for flashtool to flash from d:\...\firmware im screwed. I'll try compressing (NTFS) the c drive and hope thats enough

There is a solution, but it's slightly complicated. Proceed at your own risk, maybe do a little research to make sure you understand what I'm tell you to do.
1) Browse to C:\Users\<username>\. if you aren't already, show hidden files and folders.
2) Grab the .flashTool directory and move it onto a drive with sufficient free space (e.g., D:\.flashTool).
3) Go to Start and type cmd into the search field. When cmd.exe shows up, right-click and select Run As Administrator.
4) Change to the user directory ("cd C:\Users\<username>").
5) Make a junction point named .flashTool pointed to where ever you moved the folder (e.g., "mklink /j .flashTool D:\.flashTool").
This will make flashtool think that its settings/data folder is in the right place, when really it's just a fake folder linked somewhere else.

This time I just compressed c:\ with NTFS compression and it gained just enough space (F*ck you Winsxs).
But the above info will surely come in handy in future, so once again: Thanks! Tou've been a big help.

What a way you went through.
As you already were on 5.0.2 and rooted you just had to install xzdr to your phone.
After that you could flash one of the Pre-Rooted zip files you need.

well I know that now dont I? :silly: haha
yeah I was on a kingrooted 5.02, and should have just installed XZDR etc but I upgraded to 5.1.1 ASSunming I could root it with kingroot again, big mistake.
If I had read about kingroot not working on 5.1.1 I could have saved 24hrs worth of headaches.
Oh well... all done now. Rooted on 5.1.1, busybox installed and all
Now begins the long process of re-installing and customizing all over again *yipee*
No doubt I will go through all this again in a few weeks when I decide to unlock the BL and install a customROM And kernel
THIS is why I spent a few years with a 'dumb' phone after my HD2... ohhh the joys of flashing.
BIG Thanks to evryone who helped me out on this especially Xasbo, Gamer4Life and Deathschythe33. CHEERS

Please Xasbo help, I Have loop all the time

Hmm. I've never seen that NFC message before. Did it look like that firmware update completed before the phone restarted?
Are you still able to flash anything to the phone? What are you trying to accomplish?
