Anyway, one of the two .. Decide for yourself! And the next time, please not open a new thread for this question

I would flash an ftf from the forums or make your own, as the bootloader gets updated. A failure during the OTA or PC companion flash at the moment bootloader is being updated could result in a hardbrick

Or so :good:
I could be wrong but it has mentioned that Flashtool uses the same protocols as PCC and flash tool is a way for those with unlocked bootloaders and modified system to flash stock roms where trying to use PCC would result in failure. The same issues can be experience by both methods and corrected by both (reflash in Flashtool and a replair in PCC). So as far as my understanding goes this statement seems misleading and fear inducing.
Yes, I see your point. And the risk is negligible. I just am not comfortable with bootloader being updated. "OTA".
That's just me though

I was using OTA via home wifi. If you have a stable internet, OTA is more easier.

Does anyone know when/if there will be an OTA update for the new 4.2.2 firmware? I have flashed a generic NL .253 .ftf and I also never received
the other updates OTA. I do want to update, but I want to keep root access. I know I can flash a new generic ftf and gain root access with the perf_event exploit, but just updating OTA is easier I guess. Thanks in advance!

Depends what you mean with easier.
If you're willing to wait another month (just an example) for the OTA then yes it would be easy.
You can flash the T-Mobile NL FTF, gain root, remove root within an hour. I'm quite sure that you will have to wait a lot longer then an hour for OTA to even come out.
A month does seem like an awful long time..

I just did the original Japanese xperia z 4.2.2 update and it is fine it didn't change the language or anything I just flashed it over the old one done. Is even rooted. And It has no issues. So there is already ways on getting the official 4.2.2 update.

Just download http://forum.xda-developers.com/showthread.php?t=2339421
Open flashtool
At wipe untick data and cache leave appslog ticked
This way you keep your root and your Phone will have in 5 minutes the latest version!
Done this yesterday myself
.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.
Sent from my C6602 using xda app-developers app
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..

Hi
I look after the company mobiles and we have around 30 Sony Xperia SP C5303 Mobiles
They are all on EE 4G in the UK
They run 4.1.2 (12.0.A.2.254)
Recently a few users have updated to 4.3 and now emails no longer work and the phones have become sluggish
So id like to revert back to 4.1.2
I want to keep warranty so i would like to restore from a stock rom
Id like to backup the rom from one of the 4.1.2 phones
I have read to use SUS but when i try the repair/reflash same version as suggested its not an option
The only option is to upgrade the firmware which is not what i want
Please how do i backup the firmware of our 4.1.2 phones so i can flash the ones that upgraded to 4.3?
Many thanks
The best option if you don't want to root every phone and install cwm is to use PCC to get the files if you plug one of the 4.1.2 phones into PCC and "repair" it is that an option or will it only allow an upgrade? I can do it for you I'm on EE 4.1.2 and the upgrade is not available for me yet so I can still download the 4.1.2fw if all your phones are due for an upgrade you then flash the file from PCC (there are tutorials on getting the files) with androxide and bin4rys flashtool.

Also to get the 4.1.2.ftf you don't let the repair process complete you interrupt it and pull the files out of PCC

My phone is now due an update so I can't get the 4.1.2 fw if you look for generic global 12.0.A.2.254 firmware then that will work.
Sent from my C5303 using xda app-developers app
I'm not sure: with the latest firmware being available, wouldn't PCC or SUS repair to 201 or 266?
When I recently flashed a 257 source from this forum, the phone notified me that there is an update to 254 (even though 266 was available then)
Maybe you can test one of the phones: flash a FULL 257 firmware (without wiping data) to see if it updates to 254.
Once it is done updating, the 254 firmware should be residing in one of your computer folders.
I have rooted my c6902 using z1lockeddualrecovery 2.127.8(have to flash entire ftf again cos in new 2.127.9,only twrp is working,If I press volume up it freezes!) beta installer using Towelrootv1(option3),I have backed up all apps via titanium backup pro, also backed up everything via Philz recovery (in boot)in external scard, NOW I WANNA FLASH BEST ROM FOR XPERIA Z1 LB.

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? "

Another picture
are you flashing files for 4.4? If you were on 5.1 then you should try files for 5.1.
And forget about 4.4. for now. You need to flash 5.1 and only after your phone will boot, then look for guide to downgrade.
you many need to flash the stock recovery (from 5.1) first, as your bootloader appears to be LOCKED now. after then, try flashing the stock 5.1 files. if successful, then you can unlock again via sunshine, flash TWRP recovery, then try to upgrade to 6.0. I'm pretty certain you should not try to downgrade, as that tends to cause problems.
Thanks
Just I'm downloading 5.1
