Hi All
Today i was curious to try out the MIUI firmware so i flashed it to my Xperia S which has a locked bootloader. The phone is currently on the 6.2.B.1.96 kernel.
Now i dont like it and i want to revert back to the stock firmware but the recovery mode wont start up when i press volume up when it boots. I made a Nandroid Backup of my stock firmware and Nandroid Manager still detects that i have CWM 6.0.30 installed on my phone
Before i installed MIUI my phone was rooted and i had installed CWM 6.0.30 for locked bootloaders onto it. I was thinking of flashing the 6.2.B.0.211 kernel onto the phone using flashtool by bin4ry, rooting it and then reinstalling CWM 6.0.30 but i dont know if i should do it or not
Does anyone know what i should do?

Do you just flash a kernel/ROM or something ?
I have rooted my phone
Download pvyParts Xperia CWM Installer from Google Play.

Nevermind my post
You got to flash a kernel through fastboot on your pc first.
Most kernels will have recovery(CWM) on them which you use to put a new ROM on.
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.
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 ?
Hi
Hope you can help. My aim originally was to upgrade from 4.0.3 to Slimkat 4.4.4 but I have never done anything like this before and I have messed it up. I was using this guide http://droidors.com/2014/07/07/upda...android-4-4-4-kitkat-with-slimkat-custom-rom/ but deviated from it when the guide didn't work for me.
I upgraded to 4.0.4 using PC Companion.
I unlocked the bootloader on my Arc S and rooted using Eroot. Then I tried to install a custom recovery from here http://forum.xda-developers.com/showthread.php?t=1345741&page=2 which said I had to go back to 2.3.4. I did this using Emma from Sony Mobile.
After the custom recovery tool installed I loaded the Slimkat files onto the sd card and booted to the recovery mode but got an error when trying to install Slimkat (it said something about the update is for LT18i but my device is "" (which it isn't?!)
Anyway after that didn't work I wanted to just go back to normal 4.0.4. I couldn't get Backup TA working before I unlocked the bootloader so I have lost the DRM keys.
The custom ROMs I have seen all seem to require stock 4.0.4 so I seem to be stuck on 2.3.4.
I am so confused, if anyone can help either with getting me back to a version of 4.0.4 or my original goal of Slimkat that would be much appreciated.
Thank you

You can anytime revert back to 4.0.4 stock rom:
1. download flashtool http://www.flashtool.net/ if you don't have it already.
2. download stock firmware from http://www.4shared.com/rar/cwrJE_jE/Lt18i_41B0587_1254-8596_Generi.html?refurl=d1url
3. Placing firmware in flashtool. Note: only .ftf format files to be placed. If the file is of .rar/.zip then extract it to get .ftf file
Copy .ftf to C:/>flashtool>firmwares
4. Run Flashtool>Click on the flashing button>Select flashmode>Ok
On they very left side you'd see the firmware name and version. In the middle the contents of it and on the very right side some options. Mark them as shown below.
5. Select OK. Now flashtool will prepare files and ask you to connect your phone. Follow the steps.
On devices with no hardware back key, use volume down key while connecting
OR
after that use this to root:

then you can flash any 4.4.4 rom
hi guys,
first of, forgive me If I cannot utilize google or xda's search engine for looking a good solution to my issue, I just cannot think of the right keywords to look for.
for several months now, I currently have CM11 fxp334 by pencam and Bootloader is unlock. Recently Im encountering random reboot issues and I think its getting worst and I am not sure if it has something to do with my link2sd, because at times when it does randomly reboots, I lose some apps that are link to my sdcard after booting.
1) Im thinking of either updating to the latest CM11(or CM12) nightly builds (I have cwm obviously) to assume that latest builds have less bugs
2) or is it possible to use cwm in trying to install/flash stock xperia M firmware because CM seems to be a power hog based on my own observation vs stock sony 4.3 JB. If this can be done, can some good soul point me to the right direction please.
I have my rest days, I hope I can use it by fixing my phone. Thank you.
Just flash your stock .ftf file to go back to stock.
You will have to reflash recovery tho.

flash by using cmw, or flashtool? can cmw recognize a *.ftf file?
and when you said that I will have to reflash recovery, I can still use the cmw recovery that Ive previously used with my CM11 together with stock sony rom?

flash .ftf using flashtool flashmode
afaik cwm only support .zip file for flashing
you can have cwm on stock rom when you flash stock kernel that includes cwm
flash it with flashtool fastboot mode
just press thanks if it's helps instead of typing it
