Root without pc!!?? HELP

.I want root my XZ with any app (without pc). Please help.

not possible
C6603 ?

I think it would be possible, if you ask me, but you would have to execute all the commands from your phone, by hand.
Very risky though. If you make a mistake you could brick your phone and have to reflash using a pc.
Not recommended!!
Also you would need some knowledge about how android works, before you try anything.
Just use a pc. That's a lot safer and way easier

Actually you need a PC anyway, actual rooting method implies downgrading the kernel, rooting, and upgrading the kernel. You need a PC to down/upgrade the kernel.

Well, you're right, in the case of newest firmware. Older firmware doesn't an need old kernel, so it would be possible.
But for .67 firmware, yes you really need a pc.
Didn't consider that since I'm on unlocked bootloader, so don't need difficult rooting processes

Well, you need a PC to unlock the bootloader and flash rooted kernels, and actually the last two firmwares need kernel downgrading on locked bootloaders, .244 and .67. Sorry i'm just beeing picky

Ask me how do it.If it will easy for me I do it.

Well he only wants root, so unlocked bootloader isn't the subject here, neither are the rooted kernels.
I thought 244 was rootable without kernel flash, but i believe you in that..

[Q] c5306 customization number

Hi there... does anyone have the c5306 customization numbers or knows if the c5603 ones work with the c5606?
I have read/search through the forum but i havent been able to find the answer to my 2 questions.
I stumped into this post and hence my 2nd question.
All i want to do is flash the 12.0.A.2.254 kernel on my SP via the build.prop + Companion method, so if anyone has a better way or suggestion i'll be happy to read it, thx
(already rooted my SP)

Oh cmon guys, anyone? Or perhaps an advice in how to get my phone updated if there's no firmware updates available in my country?
Sent from my C5306 using xda app-developers app

just use flashtool and any .ftf
my phone is UNBRADED, I live in Mexico and I use o2's firmware...no problems

Sweet, wth i'll try right now... Thx for answering dude

So, turns out c5603 firmware DOES work with the c5606, LTE working and all, I haven't seen anything wrong (besides the obvious wrong model showing on the phone info) so far.
Flashed the Deutschland LTE ftf via flashtool.

if you have a ta backup you can unlock and relock the bootloader without any problem like the first day. even the sony cant realize that.but if you dont want to unlock the bootloader i think iHackers and RomAur are best.fast and stable
but you may have some issues with Xposed Framework (which is really handy) in LB.
but these two i think are the best based on stock roms
for note,I'm using iHackers v4.1 with unlocked bootloader

Ya I have many ta backups. But I shud unlock only after 6th Oct,my lifestyle is too dangerous to ignore warranty (I KNOW SONY CANNOT IF I RELOCK,STILL.. As I have no personal pc..ll buy in Oct)o thanks anyway.. M downloading ihackers 4.1 minimal version now.

If you relock bootloader via TA backup, no one can notice that .means sony cannot realize it and your warranty stands.
and i think,i think,if i'm not wrong, rooting the phone will break the warranty .. ! again i'm saying, i think

Sorry, I just saw the rules..no best' rom thread allowed. I tried to edit but in vein! Sorry...
Hmm...m searching Sony.Co.in about this pal... "Does root void warranty? "

Can it be possible without rooting my device then please let me know friends.

You can use Flashtool to download and flash your country's firmware. No root required.
See: How to package and flash stock roms in FTF format.
I noticed you're from India. I already packaged a stock 10.5.1.A.0.283 generic Indian FTF for the C6602 that you can use here.

Brother I already use android 4.4.4...
But can u tell me the step wise as I am new to xperia earlier I was using micromax.. So please can you guide me step wise
Sent from my C6602 using XDA Free mobile app

If you go to the guide that I linked you to in my earlier post, it tells you how to do everything step by step with images.
Download the stock rom I linked, then follow part 1 and part 3 of the guide. I cannot explain it any better than the guide I already created.
