Default [Q] [noob][Xperia T][4.3] Update to hybrid 4.3

Hi all,

This is a noob question, I’m sorry, but I figured I’d post the question and explain what I understood so others could benefit. As I’m a new user, I’m posting here and not in the development section.

After looking at the new 4.3 ROMs, I figured peetr_ hybrid ROM (http://forum.xda-developers.com/show....php?t=2627922) looked good and I am now trying to figure out how to install it.

Right now, I have a Xperia T (LT30p) with CWM-based Recovery v6.0.2.7, Doomkernel 3.4.0 and XperimenT 2.3 (i.e. JB 4.1.2).

Here is how I planned to update [order and wording changed following Alex5699’s comments]:

1) Download a new Kernel, one of the two mentioned here: http://forum.xda-developers.com/show...6&postcount=13 . One of them has no recovery, so I figure that if I flash one without recovery, I will loose recovery? So I think I will choose this kernel http://forum.xda-developers.com/show....php?t=2604492 in its zipfile version and put it on the phone.
2) Download the zipfile from here http://forum.xda-developers.com/show....php?t=2627922 and put it on the phone.
3) Go into recovery.
4) Do a factory reset(=wipe data), wipe cache and wipe dalvik cache.
5) Flash the ROM. No reboot before the next step!
6) Flash the kernel.
7) Reboot and be happy.

I just wanted to check if this is the right order (if someone agrees I’ll update the post to remove the question marks) and that I’m wiping the right things. I suppose wiping these things does not erase the content on the virtual sdcard in the phone. At least that’s what I think I remember from last time.

Thank you very much in advance for your help. Have a great day!

Sorry, just another question, I want to make sure the explanation is right. On the thread http://forum.xda-developers.com/show....php?t=2627922 , there are these two comments that made me think.

First, there is the prerequisite:

- stock based 4.3 kernel
- working recovery
Iím not on a 4.3 firmware right nowÖ

I thought I could get around this but then there is this explanation here:

And later I suggest to flash amss (baseband) from ftf.
which Iím still trying to understand, but I fear thereís something Iíve missed.

Iím sorry if Iím asking noob questions; if my questions are too annoying donít mind, Iíll try to find the right solution and if I do, Iíll post it here.

we do have an official 4.3 out now for the T so basically hes saying latest 4.3 firmware (mainly baseband/radio)(flashtool or official way)
- stock based 4.3 kernel
- working recovery is needed if u wanna flash the hybrid rom .. but since ur on a 4.1.2 rom you jus follow the steps u posted first .. and when they said to flash rom and then kernel without reboot they mean right after rom is install "while on 4.1" go to install again and select the kernel then once thats install then u reboot and allow your phone to boot up .. first time boot may take up to 5 mins so be patient

Thanks a lot!

In other words, youíre saying (just to make sure I understood you correctly):

1) No reboot between flashing the ROM and the kernel. (I had understood that, but youíre right, I should correct that above, and I will).
2) Itís not an issue if Iím not already on a 4.3 kernel (although itís written in the prerequisites), as long as I follow the instructions above. [For others reading this, there is a list with stock firmwares here for instance http://forum.xda-developers.com/show....php?t=2648320 .]
3) There will be no need for separate baseband flashing (there is an explanation video on youtube for the Xperia Z for those who donít know how to do it, I canít post the link as a xda-noob =D) or for flashing a separate recovery (since the mentioned kernel has already a built-in recovery) after following the instructions above, and no need to fear not recovering my mac-address.

Donít worry, Iím not asking you to give me some kind of warranty, Iím just trying to make sure I understand what youíre saying.

Thanks again for being so prompt in answering!

If I manage to update properly Iíll post back!
