A few months ago I flashed xzxperience 2 rom and RaymanFX kernel, this was before official Jellybean rom from Sony was released. My bootloader is unlocked and I want to install official the Jellybean update now. I tried DooMlords rom but it wont flash.
What do i need to do? I dont think I backed up stock kernel as I cannot find it, only stock ICS rom I backed up using clockwork recovery (does that back the kernel up I wonder?)
Can I just use Sony PC companion or OTA update?
Thanks.
No, you can't use PC companion or SEUS when you have an unlocked bootloader.
Have a look in the FAQ of the XPERIA S Development forum and see if there's a ICS ftf
There should be some ICS .45 and .55 ftf files around somewhere.
I believe you can now root .55 so it should speed up your progress to an install of the pre-rooted JB ROM.
That said, DooMLoRD provided a few fastboot 'elf' kernels that you can use to get CWM recovery mode access and then flash the JB pre-rooted ROM.
Best to have all the zip files you need on your phones /sdcard before you start any process though.
If you can't flash the pre-rooted official 6.2.B.0.200 ROM, you can install a leaked version of JB, then install DoomKernel, and you should be able to install the pre-rooted official 6.2.B.0.200 ROM and then DooMKernel again. that's the long way of doing it.
I believe if you're getting a status 7 assert failed, DooMLoRD has a fix for that too, with an ICS kernel/CWM recover of some sort.
I believe there are pointers in DooMLoRDs pre-rooted JB ROM install procedure.
As an aside, I had RaymanFX GPU/CPU over-clocked kernel installed too and found it really good.
You can use EMMA tool from Sony for unlocked bootloaders to go back to stock rom or flash a .200 ftf file with flashtool.
Other option is to flash Doomloards prerooted ROM with CWM or in case you don't have CWM (or CWM on ICS kernel and errors during flashing), first flash Doomlords advanced stock kernel which includes CWM via fastboot / flashtool and than his ROM with CWM.
thanks for the replies guys, I managed to get the doom stock jb rom working in the end, followed the tips in the thread and had to flash Advance Stock Kernel with Recovery v01 (FW 6.2.B.0.200) (CWM 6.0.2.7) before I could install the rom
I will remember in future then if I want stock rom to relock the bootloader.

What would be the best way to run stock 2.3.4 rooted on an R800i? The stickies are outdated around here and all root methods I've seen refer to 2.3.3 or 2.3.2.
Would the best way be to root on 2.3.3 then update to 2.3.4 OTA and use something like OTA rootkeeper if I want to keep the stock kernel?
If I am unlocked can I just ftf or update to the current stock firmware and then fastboot a kernel with root built in like doomlords kernel? Is that the best method if you want a custom kernel but stock 2.3.4?
Really I am looking for the best way to run stock rooted 2.3.4 with a stock kernel and with a custom kernel to compare.
Yeah, you can flash any stock rom using a ftf file and then update the phone to the latest version with OTA or PC Companion, but i think neither of them works if your bootloader is unlocked. In this case you must find a ftf file with the latest 4.0.2.A.0.62. I found it on this thread: http://forum.xda-developers.com/showthread.php?t=1409355

download the stock rom (there are many threds here that offer the link) and download flashtool. you can flash the rom and root it right after you flash ir with flashtool
Full stock ROM 6.1.A.2.55 for Acro S with ROOT and CWM
So, its the easiest way to get last stock rom with ROOT.
Installing wintout unlocking bootloader:
At first you need previous rom with ROOT and CWM.
Unzip archive and flash ftf file via flashtool wintout any wipe!
Copy StockRom_6.1.A.2.55+root+cwm.zip mirror on your SD Card and install via CWM. (If you want clean ROM, wipe all before installing)
Done
You can change the order of steps 2 and 3
Testing now. Yesterday, I had to repair my phone (by PC Companion) after trying to root 2.55 firmware
any update on working root on 6.1.A.2.55 LT26W? thanks

im searching for firmware that would make the battery last more. and now currently testing diff custom/orig roms. thanks again
success installing the update firmware without loosing my data and customizations. thanks sir Desperanto86 and ngonchan
note to all that might try...without any wipe!
first thing i noticed is the app Sim Toolkit if missing but the system says its installed.
*#*#7378423#*#*
Rooting Status:
Bootloader Unlocked = Yes
means my bootloader is unlocked right?
can I still flash this ftf file via flashtool? (I heard unlocked phone must not run the OTA update... so I wonder if this has the same effect)
thanks
I finally buckled up my balls and proceeded with flashing this...
but I lost CWM by flashing the .ftf file (I got my CWM previously from this kernel http://forum.xda-developers.com/showthread.php?t=1834129), so eventually I guess - after replacing the kernel(?) I lose the CWM...
so I flashed that kernel with CWM by cobrato again to flash the ROM, it went well
even though I now have .55 ROM + Kernel + Root + CWM & everything, I realize that the kernel by cobrato is slightly older than the one posted by OP

I started with stock 6.A.2.45 with root and CWM, flashed the OP's ftf file without any wipe and CWM still there, then apply the zip and done!
ashy, you have CMW in kernel...when you flash ftf file you flash stock kernel and lose CWM. My way for people with locked boot + stock kernel and CMW in ROM!
ngonchan, you have CWM in ROM and don't lose it

you mean CWM is actually included in this ROM?
I went like this:
stock .45 ROM -> cobrato's older .55 kernel (w/ CWM) -> your newer .55 kernel (realize CWM is gone) -> cobrato's older .55 kernel (get CWM back) -> .55 ROM (full wipe) -> your newer .55 kernel...
but I still don't get CWM... (no bluelight on startup and tapping touchscreen didn't get me into recovery..)

if you have unlocked bootloader why you don't use root via cwm?
In my rom cwm already included. Many people tested it.
You should have stock kernel + stock rom .45 or .50 with root and cwm. Flash my rom via cwm and then flash new stock kernel and basaband. Or at first flash kernel and baseband and then flash my rom. And full wipe BEFORE installing ROM not AFTER!!! Go to CWM, FULL wipe and right flash rom

I want to try .55 ROM, but having unlocked bootloader - PC companion will not let me update... so I have to do it this way...
umm... is your method of getting into recovery the same as others? (tapping screen at sony logo?) weird... it didn't seem to work for me...
I forgot whether I wipe before or after installing the ROM could it be the reason?

I was on official ICS till now, and I'm not very familiar with android's custrom roms, rooting, etc. I wanted to get JB via CM10 on my phone, so today I unlocked my bootloader on my Xperia S LT26i using this link (unable to post links so google it) Xperia S : Update to Android 4.1 Jelly Bean with Cyanogenmod 10 on androidlegend .com
It was mentioned that I should be having clockwork mod recovery on my phone and used this link to get it - How to Install ClockworkMod Recovery on Sony Xperia S on android.gs
I haven't rooted it, now it's stuck on clockworkmod and I don't know what I should do! Am i bricked? please help
ps: i used cmd to flash nozomi-recovery.img
Do you have cm10 downloaded on your fone already as a zip file? Or was it last still running ics?
Sent from my Jellybean Xperia S
It was still on official ICS, only with an unlocked bootloader, didn't do anything else! I'm a noob to all this so please bear with me
On a laptop/pc. Download advanced stock kernel and follow the guide here - http://forum.xda-developers.com/showthread.php?p=23181182#post23181182
Then you should be able to boot to ics again and be rooted with cwm. (keep pressing volume up when the lights come on on boot up)
Then if you already have cm10 downloaded on your fone just choose flash zip from sd. If not. Boot back up and download the rom before booting into recovery and then flash zip
Sent from my Jellybean Xperia S
Is it okay if I directly download JB rom and flash it via cmd fastboot instead of downloading stock ICS and flashing it?
As far as I'm aware you can only fastboot the kernel file. Hence y if you were on ics you need an ics kernel so you can boot up to download the cm10 rom to the sd card
Sent from my Jellybean Xperia S
So now I'll need to download stock ICS rom, flash it via fast boot and then download CM10 JB and then flash it via CWM? Thanks for taking your time to help me out..
You might find that just fastbooting the ics kernel will make it all work again as you've technically not changed the rom yet. Just the kernel file. If not just download a stock ftf firmware file. Flash with Flashtool and then start again using advanced stock kernel first.
Always keep a copy of the advanced stock kernel zip on your sd card. It's very useful even if you're on cm10 as some of the cm kernels wont flash properly

Hello,
i'm sorry if the question has already posted but i still haven't understood what to do.
I'd like to try a modded .200 rom and i'm driving an EOS rom at the moment.
What i've read is that to installa a .200 i need to go back to .55, root it, install original .200, roor&recovery and then install my preferred rom.
What i'm asking, is there a way to straight install a .200 rom? If i download a .200 original .ftf, can i flash it over my EOS rom, root it and then install my preferred rom without going trough a .55 rom?
Doesn't a .ftf install also the baseband and kernel?
Thanks

You don't have to do all that. Since you are using EOS rom , your boot loader must be unlocked so just download the .200 ROM and a .200 kernel like doom kernel or trinity kernel. Place both on your SD card. Then first flash the kernel in cwm. Then reboot and again enter cwm. Do all your wipes and flash the ROM. And yes, ftf installs the baseband also.

I'm looking to flash my Xperia zl but the process requires flashtool and a original firmware. My question is what good is cwm? Can we not flash roms from recovery like I do on my Transformer 700?
Or do I really need to use flashtool flash a original firmware reroot then go to recovery factory reset wipe and then flash New Rom?

Flashtool is only needed if you want to flash Sony stock rom or kernel files.
For flashing any AOSP rom (like CyanogenMod or PACman rom) or mods you need cwm recovery.
If you already have cwm just reboot your phone. On startup Sony logo just press volume + or - to enter cwm.
If not, I recommend NUT's DualRecovery (http://forum.xda-developers.com/showthread.php?t=2288118).
With locked bootloader you are not able to flash any kind of AOSP kernel.
AOSP roms need unlocked BL.
Flashtool can unlock your BL if its rootable (some carriers do not allow this).
BUT:
Before unlocking BL, make a backup of your TA partition! --> http://forum.xda-developers.com/showthread.php?t=2292598
thank you
I seen a Rom for locked bootloaders and I thought why can't I just flash this way I did with tablet I got the Rom for a locked BL.
I got the RomAur 9.0. Thanks for quick reply wasn't sure if I should proceed or not till I cleared that up.

I'm running eXistenZ Ultra Edition http://forum.xda-developers.com/showthread.php?t=2385313
You should try it, at the moment its the finest rom for our beloved ZL
This rom is based on .67 stock rom. Before that I was on .423 stock rom.
In order to run without problems, I had to first flash .67 stock rom with flashtool, reroot, reinstall DualRecovery and then flash eXistenZ rom.
So if you're going to flash a custom rom based on a different stock kernel than the one you're already on, first flash that stock rom with flashtool.
You can skip this step, but you might run into connection problems with wifi and data.
First flash .67 stock rom with latest flashtool.
Use this guide to get root access: http://forum.xda-developers.com/showthread.php?t=2388946
For the 11. step use this .67 kernel: https://drive.google.com/file/d/0B0duxzJgPpcyX3hhbV9wVFQ4R0E/edit?usp=sharing
You have to close flashtool BEFORE you use DooMLoRD_Easy-Rooting-Toolkit_v18 !
After the root, flash NUT's "lockeddualrecovery2.6.3-RELEASE.windows.zip" : http://forum.xda-developers.com/showthread.php?t=2288118
For the rooting process you'll need "unknown sources" and "usb debugging" checked.
Take care to follow every step as described and you should be good again. :good:

After everything is done, don't forget to wipe dalvik cache..
So if i can summarize, if I don't need to flash CM or AOSP Roms, and only flash rom based on Stock I don't need to unlock the bootloader ?
If I use flashtool 0.9.13, it won't unlock the bootloader ? because while i was reading their welcom page http://www.flashtool.net/index.php
I had a feeling that it unlock the bootloader, is that an option or it do it when i flash a stock rom with it ?
What are the advantages of unlocking bootlader a part from being able to flash CM AOSP based rom and kernels ?
