I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader
I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/2013/11/how-to-go-back-to-stock-firmware-on.html
and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?
Can I just go ahead and do this or must I relock bootloader first?
please help me since I never done this before, only rooted and unlock that I did.
Thank you so much folks

I downloaded stock C6902_14.2.A.0.290 which is 4.3 it's the tft file
can I just flash it using flashtool? I want to wipe everything, no need to back up, I mean I want it to feel like a brand new phone. like factory reset.u know, and It doesn't matter about root or bootloader,

if you don't want to relock your bootloader then just go back to .290 with flashtool

Thank you, I'll do that
done
I'm finally back to stock ROM and it's much faster than custom ROM
I think it is much more stable too.
I'm no longer rooted anymore but bootloader is still unlocked.
I'm happy now
You can install custom kernel & have root

custom Kernel ? what is really a function to flash a kernel, I mean i have stock ROM, isn't the kernel already compatible? to root, maybe in the future,
Will I be able to update firmware via Sony PC companion? now .290

If you have an unlocked bootloader, you will not be able to update using PC Companion. I didnt know all this **** were involved in Sony phones.
I had unlocked my bootloader a couple of days back, didnt know I had to backup my DRM keys and ended up losing my warranty. Now I cant even update my phone using the official updating method.
BTW... the recovery is bundled with the kernel, thats why people refer to it as flashing a kernel instead of recovery. I didnt know this until 2 days back.
Thanks

please teach me the easiest way to relock bootloader
Thanks
done relock bootloader
Thanks anyway but I found the method and my phone now relocked bootloader
If you do have a TA backup then you don't have to do anything else then restoring it on a stock rooted firmware..If you don't then use flashtool to relock it..
Revert back for more help..

If I am on a Locked Bootloader and on a rooted custom ROM, will Sony PC Companion detect my phone when the next update comes??
This is stupid. If you are in 4.3 (.290) with un-locked boot loader you cant update via PC companion or SUS.
I ended up going to 534 (4.2) via flashtool. Root it, restore TA backup and then use SUS to update. And flashing the latest 4.3 via Flashtool din work.
No PC Companion or SUS won't detect your phone.. You've to manually flash a valid ftf from Flashtool.. Then you can connect & update your phone through PC Companion or SUS..

Do you still have the files? I'm looking to revert my C6602 (US) back to factory settings to I can allow PC companion to update the software.
(I'm looking to give the phone to someone, and they wont want to mess around with flashing and so on)
I'm using z1 stock rom lolipop
I tried in last two days king root its failed twice on version 4.1
then i found somewhere 4.0 with working root i tried and sucess!
then i installed titanium,greenify used phone for a day now want to backup drm for going to install custom reovery and custom roms !!!! what are my steps i failed during taking backup on drm keys..... what should i do i tried factory reset my phone now king user inside but phone is not rooted..... !!!!!!!!!!
Hello community,
this is my first post here so i hope, i do it right
Please excuse my english, it is not perfect.
I have a xperia z with Android 4.2.2 (10.3.A.0.423) . The bootloader is unlocked, cwm/twrp dualboot is installed, also the doomlord customkernel v19 is in use, root-access is available.
Is it possible to update to official stock firmware 4.3 (10.4.1.B.0.101) using the PC-Companion without bricking my phone? Root-Access and cwm and so on would be lost as i assume. This would be ok for me.
I really would like to do it that way. I think, as an alternative, i could flash the 4.3 stock rom using cwm? Going this way, will my data and all settings be lost?
Updating via OTA is not a good idea i think.
Thanks for advise
Greetings

Well, you cannot update via PC companion, Sony Update Service or OTA, as your bootloader is unlocked.
So, that leaves updating via Flashtool or flashing a prerooted rom from the development section.
The cleanest way would be via Flashtool, then simply flash a custom kernel again and root.

And if im going to flash the stock-kernel which belongs my current firmware and then relock the bootloader?
If the bootloader is relocked, i can't flash a kernel or something else anymore right?
EDIT: If I decide to flash a rom will my data be lost or is it like im doing an normal update?
Is it possible to go back to stock with everything?
So much questions Sorry, I don't know that much, please help
Can anyone help?
Yes, if you relock the bootloader, you should be able to update via the normal methods (at least via PC companion, unsure about OTA). A locked bootloader means you cannot use custom kernels.
If you flash with Flashtool, you can choose not to wipe your data.

I assume, it would be the best to flash the original kernel before i lock the bootloader?
After relocking the bootloader and installing the update via PC-Companion, will the kernel be the "original" kernel and will cwm/twrp be still there or not?
Yes, flash a stock kernel before locking the bootloader. If you don't, you will soft brick your phone.
After updating, you will have a stock kernel and your custom recovery will be gone as well as root.

So everything worked fine. I relocked the bootloader via flashtool and installed the firmware using PC-Companion. My Xperia Z is now totally "stocked"

Okay .. So I'm running ver. 14.3.A.0.681 on my Z1 and I want to root it .. I heard of a method in which the phone must be downgraded, then rooted, then reupdated again using flashtool .. But every time I try to downgrade I get stuck in a boot loop .. I have managed to fix the boot loop problem by reflashing the 14.3.A.0.681.ftf
Please guys how can I downgrade without having this problem? And does this rooting method work? If not, what should I do?

Hi ralph97,
Here is what I did (although I was on .257 to start with)
1) Flashed C6903 14.1.G.1.534 Generic from here - http://forum.xda-developers.com/showthread.php?t=2469191
2) Install dualrecovery from here - http://forum.xda-developers.com/showthread.php?t=2261606
3) Flash SuperSU (via recovery) from here - http://download.chainfire.eu/282/SuperSU/
4) Update to NUTs .681 from here - http://forum.xda-developers.com/showthread.php?t=2687443
Each time I flashed an ftf, I cleared everything, so I made a backup (I just copied the stuff such as music, photos etc to my pc)
I hope that this helps.
PS - all cradits to helping me to @gregbradley

Alan
If you open the BL there is no need to make all the way back to 534.
You just have to open the BL install a recovery, on the 680 ftf, and then install the supersu.

Yes this is true, but you may want to backup your TA partition before unlocking the bootloader and this needs root, so you have to downgrade to .534 anyway.
So, yes technically you can do this, but I DO NOT advise it.
Well, the first time you do it, probably it shoud be done as you say. :laugh:
i also do that...its work..dont need to downgrade..

I hoped you backed up your TA....
You need root to do it, so it has to be done BEFORE you unlock.

Please remind to People the consequences in doing this! Like the Warranty, after Unlock Bootloader, will be Voided and even before that, like @gregbradley already said, Backup TA to not lose DRM Keys. The short way isn't the best all the time.
You do not reupdate by flashtool.
Only with the recovery.
Damn my thread got locked.

You still need to flash SuperSU to get full root, but in step 4 just flash the ROM of your choice.

No, 5.1 cannot be rooted directly. Root is only possible on 5.1 by flashing a pre-rooted ZIP.

Flashtool doesn't need root privileges.
With flashtool you flash ftf files.
You need flashtool program to flash ftf.
Your phone has to been in flash mode to flash a ftf file. The phone comes with flash mode, that's nothing special. The phone can handle flash mode from build.

Overheat ? how ? there is no way... i have never even gotten over 50 Celcius... are you sure you don't have Z3+ ? D
Like what @xasbo said, this has been answered again and again, pls. use the search button.
There are no existing direct rooting method for 5.1.1 at the present time. Use flashtool to flash 4.4.4 or 5.0.2 on you phone then root it then install a custom recovery then flash a pre-rooted 5.1.1 on your phone. That is the only way you have at present if your phone has a locked boot loader.
If your phone has an unlocked bootloader, I believe you fastboot a rooted system.img or something to get root access on your 5.1.1 without the need to downgrade to either 4.4.4 or 5.0.2

Ah, yes my apologies I mixed system.img vs. system.sin, if you are making a pre-rooted 5.1.1 use this thread it details how to create a pre-rooted 5.0.2 but it is the same for 5.1.1
