Hello there,
To start off, I am new to Android system but now, I am comfortable at using it.
My Device: Sony Ericsson WT19i
Firmware Version: 4.0.2.A.0.58
Root Status: Rooted
Did some googling on how to root phone, and successfully rooted my phone and same time found out that .62 version of my phone's firmware is not rootable so stayed positively there for a month.
Now seeing other users CM7, CM9, CWM(ClockWorkMod) and other stuff which I don't even know made me crazy to test them out too. Besides, sony's stock rom is getting on my nerves.
So, what do I do now? Could anyone direct me on
1. Updating to .62 and still be able to root.
2. Custom Mods? How?
A big thank you for going through this.
Regards,
GaNi
first unlock your bootloader and flash custom kernel..

Doing OTA update on your phone will keep root. It means, if you have .58 firmware and root, and you do update via 3G or Wifi on your phone to .62, root stays the same.
For custom mods, you should first get familiar, what is ROM, kernel, what these do. Then it will be easier for you.
As for custom ROM, you will need custom kernel, which will require unlocked bootloader, which can be done via official method on Sony website, or via test point method(S1Tool). Either way you lose your warranty.
Regarding bootloader, look at screenshot please.
Do I still unlock it?
@someguy
The country which I reside costs a freaking lot for an MB, OTA updates could be my last alternative.
PS: Could we able to set the status back to normal so it doesn't look like it got it's warranty voided?

Yes, you can unlock the bootloader, both ways.
You can later on relock bootloader, then it will appear like this again.
OTA update can be done over WiFi also on your mobile.
Tried to do an OTA. Now it shows my phone is already on the latest software. No idea.
I decided to flash it with STOCK .62 ROM.
Is this ROM good to by flashed with? http://forum.xda-developers.com/showthread.php?t=1560660
Author say's it rooted already. I'll just use a flash tool.
try to unlock bootloader first
Unlock bootloader on .58?
You say if I have .58 rooted phone and make OTA with Wi Fi, my phone will still be rooted. I try that, download update, mobile restart itself, but and the end of process show message "Error, cannot update"
I dont wont to unlock bootloader because I dont need custom kernel, I only need update stock kernel .62.
Thanks for reply.

Custom ROM also requires custom kernel.

is kernel changing with changing rom or it stays until you change it?

I think you need Flashtools to flash a custom kernel (assuming the bootloader is previously unlocked) with ClockWork Mod (CWM) bundled.
After flashing the custom kernel, you reboot into CWM mode (depends on your phone model), erase system memory and install the new ROM (which should be in a .zip file in your SD Card).
Was anyone able to get "Ad Hoc" wpa_suplicant working for Live?
Hi,
I rooted my Z2 tablet a few days ago and have found that I don't really need the advantages it brings (from what I can tell). SO - I want to get it back to the way it was when I first opened the box.
I have seen threads about different devices and how to restore them to factory or stock (??), but they seem to call for specific files or flash software. So that brings me once again to this forum to figure out whether anyone can direct me to some instructions on how to do this. I figure it shouldn't be too hard. Just being careful.
Thanks very much for the advice once again.
I think if you flash the rootable kernel again, you could use an unrooting tool to undo the root. I'm also aware that there are files that you can flash to re-lock the bootloader (I once did this with an Xperia mini pro, although I'm not sure if such file exists for this tablet) but the DRM keys are lost forever a.f.a.i.k. But at least if you manage to re-lock the bootloader you will be able to install F/W upgrades through official ways again.

Anyhow, you won't be able to restore to (more or less) factory status without at least flashing a couple of files.

THank you for the response. Unfortunately i'm not even sure how I would go about flashing 'the rootable kernel'.... Feeling a bit foolish for getting into this actually.
From what i'm reading, it seems like I need to get the stock software and start again. So i'm looking for the 'FTF' for my tablet, which is a SGP511. Not having any luck though.
Which was the process that you followed to root it?

It was on another site - can't remember which. It got the clockwork mod installed. I think? Or was that just a recovery thing? No idea.
I'm actually now just doing a factory reset to see what happens, and it said 'root access possibly lost' in the process, which I thought was a good sign. Guess i'll keep tinkering with enough caution to eventually get the warranty back in tact.
Hopefully the loss of DRM doesn't effect the warranty.
In that case I guess you will have to download a firmware ftf file of an official unmodded firmware (preferably one of your region but I think especially if you have the wifi-only version it doesn't matter much as long as it contains the interface and input languages that you need), and install (or "flash") that using Flashtool. After that the root will certainly be gone and if you could then find a file to relock your bootloader I think your warrenty will be fine. I honestly don't think that Sony service and repair personel will check for DRM keys every time before repairing a device.
UPDATE
Factory reset appears to have gotten things back to normal. My plan is now just to unroot using an unroot tool (app i guess?) and then to lock the bootloader some how as well.

So it's certain that the tablet is still rooted at this moment? Some superuser apps have an option to do a full unroot, such as SuperSU, you could try that
That's great. I think that's sorted it out. SuperSU had the full unroot option and it looks like it's all sorted.
Thanks for the help.
Hey!
I just wanted to know if it's possible to go back to the stock recovery in case I want to sell the phone completely stock. So is it possible?
Yes. If you're running stock fw with root, you should be able to do a repair fw via pc companion. If not, you can easily just flash your original ftf file via flashtool. Take a look in the general section of these z2 forums. All the info is there

I have been in the General section of the Z2 Forums, and I have read about how I can flash the FTF file to my phone, but I didn't know that the FTF includes the stock recovery Currently I have a Z2 with stock fw and a locked bootloader but with root. (Running stil on .314), and I'm planning to update to .167 with a rooted update package. (http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155)
OK, if you upgrade with that method to 167, I believe pc companion will still repair it back to factory settings (not sure whether it will be 314 or 167). If it doesn't, flashing an ftf will solve your problems.

Okey, thanks!
I unlocked the bootloader and rooted my Z Ultra (c6806) some time ago. I now want to return it to stock so that it can received regular updates from Sony. Unfortunately, I haven't done any rooting in a long while, and I want to make sure I don't brick the phone, etc. Is there a simple guide for bringing it back to a stock state where it can receive normal OTA (or PC Companion) updates? As of now, attempting to update returns this error message:
Problem: The phone/tablet contains modified software that cannot be updated.
Details: Sony Update Engine Failure (error 2003).

I apologize for what seems like such a silly question. Thanks for the help.
Have you locked your bootloader? If not then I'm afraid PC Companion won't do much for you. You have to either lock your bootloader and use PC Companion again or download FlashTool and a firmware you like, then flash it.

The bootloader is unlocked, and I have not relocked it. My questions are these. I looked around the site and I found these instructions:
Back to Stock:
To get back to pure stock Sony there are several things that need to be done:
1. Make sure you have root
2. Backup any data/photos/etc on the phone
3. Restore your TA backup with the TA backup tool above
If you are on a custom kernel or ROM you ZU will not boot at this stage
4. Start flashtool and load a FTF
5. Start the flash and wait for the onscreen instructions to connect the ZU
6. Connect your ZU in flashmode
With the ZU powered off
Connect to PC while holding the volume down key
Flash will start
7. Wait for flash to complete
My questions:
I did make a TA Backup, and I have it. If I don't restore the TA Backup (which seems like a little bit of a hassle), will I still be able to update through PC Companion?
If I just relock the boatloader, will I be able to use PC Companion to update from where it sits currently (I think 4.4.2)? Will relocking the bootloader on a rooted 4.4.2 device mess it up?
If I relock the bootloader, and I am able to use PC Companion to update, I will lose root, correct? And if I lose root, I will not be able to restore the TA backup, correct, unless I reroot it?
Here's my end goal. I just want the new stock Lollipop on it, and I want to be able to receive updates (they don't have to be OTA) from Sony. I gave the phone to my mom, and I want to keep it up to date. What is the easiest (and safest, least-likely-to-brick) way of accomplishing this?
Thank you for any help.
i have my ta keys backed up but noticed you cant relock a bootloader when using a custom kernel is there any other way to restore my drm functions without going back to stock (its a kernel to get root thats all)
i have fw build number 34.3.a.0.252 (reason i needed root is disable the update notification)
