Hey everyone,
last week I flashed my girlfriend's XMS with several custom ROMs, but none of them could really satisfy us, so I want to re-flash the stock ROM.
My question is: Can I just flash the ftf file with the flashtool if there is currently CM11 running on the device? Or do I need to erase the system before?
Will this also flash "stock recovery"? Is there a way to do this?
Thanks!
Yes, you can flash stock ROM. There is no need to format system, Flashtool will do its work. Stock recovery will not be flashed, because we don't have stock recovery on our device. But you can flash stock kernel with CWM or PhilZ Touch recovery.
if you want to leave your recovery ..check kernel
sin in exclude list in flashtool

No! Phone will not boot with custom ROM kernel (if custom ROM is not based on stock). So it is necessary to flash full stock at first and then to flash stock kernel with recovery, if you want to have recocery.

You flashed stock via Flashtool after CM11 or CM-based ROM without flashing stock kernel? It should not boot, I think, because 4.3 and 4.4 kernels are different.
Has anyone tried this? I need to do this also but I'm a little bit confused about flashing kernel. I tried to find a detailed guide somewhere but no success

Hi guys any 1 can help me i want o install 1custom ROm but i flash and all and they dont boot i dont now why :S
and other questions where cna i fidn ftf files? for stock ROMS?
xd
BUMP
It doesn't boot because you need to flash a kernel compatible with that rom. The kernel file is the boot.img file inside the rom zip file, however, they do not always work. To flash a kernel you need to unlock the phone bootloader and use fastboot.

Yea thanks for link of Stock Firmware , and i know that i need unlocked bootloader for flash kernel but the rom i try to install its for locked phones and i try to install 3 diferent stock roms and then restore the custom rom but still not booting :S
i do wipe and clear dalvik cache i dont know why dont boot
If you flash a stock rom like NXT rom, you just need to flash the stock kernel. You can do this in flashtool, when you drag over the ftf file, check to exclude everything except the kernel for flashing. But then you're probably using stock rom in the first place. Make sure you don't flash a CDMA rom to a GSM phone and vice versa.
I had that problem once. The solution was to flash another boot image because the one that I was using was for ICS ROMS and my backup was GB. The boot and the kernel must be compatible with your ROM.
Hi, I've had my Xperia play for a few weeks and feel like i want to install a new rom as the default 2.3.4 software is a bit sluggish. Ive already rooted and installed CWM and backed it up. I have a locked bootloader and the first instruction to installing the rom is to install a stock rom, Don't i already have that installed as i haven't installed a custom rom before? Should i just skip this step? Thanks in advance! My Model is R800i and the build is 4.0.2.A.0.42.

it depends on which kernel you want to use.
.42 firmware does not support custom partition layout, so in order to use kernel like Turbo Kernel by CosmicDan or Lupus Kernel by wedgess (both with custom partitions) you'll need to flash .62 firmware or newer, wipe userdata and system and then flash the kernel.
While this isn't needed if you want to use, for example, DoomKernel

Still havent answered my question, I dont really want to unlock my bootloader if its possible to just flash the rom but do i have to flash a stock rom even though i haven't installed a custom rom before as wouldnt i already have a stock rom? The rom is a GB rom so i dont have to unlock the bootloader, it even has installation instructions for locked bootloaders.

I've said you, you should skip this if you don't want to flash any kernel with custom partition layout
But remember that if you remain on stock kernel you cannot flash no other rom than stock based ones

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,
I'm having trouble getting back from a KitKat Rom to an JB or ICS ROM.
I'm getting stuck with the firmware. It's flashing OK (I've tried several different ones), but when I boot up and try to get into CWM it just sits there on the firmware logo (e.g. the LUPUS logo, or the Rush logo).
Is there something fundamentally stopping me going back to an ICS or JB firmware, after I've previously had KitKat running?
HELP
Oh, this is the Kitkat ROM I originally installed, and it's included kernel:
http://forum.xda-developers.com/showthread.php?t=2570072
If I flash that kernel again, I can get into Kitkat successfully, no problem at all.
As above, if I flash any other kernel, I just can't get into CWM.

You can flash stock ICS firmware using Flashtool, then flash a JB custom kernel with a recovery. From there, use the recovery to flash a JB ROM.

Thanks for your reply.
What is the need for flashing an ICS kernel first?
I'll give it a go, but flashing a custom ICS kernel with a recovery I've been unable to get into CWM.
I'm probably doing something really stupid.

Flashing ICS is recommended first since this will restore you phone's memory partitions. KK uses different memory partitions to make it run properly. This will also wipe your phone's data and allows you to do a clean install that should eliminate most errors that you encounter during ROM installation.
Ok, thanks so much for the advice
I'll give it a go and let you know how I get on!
Ok, I'm back on Gingerbread stock firmware
Android v2.3.4, Build 4.0.2.A.0.62.
I can't find an ICS based FTF file - everything is either 404 or on hotfiles, which is dead.
I've unlocked the bootloader (which I thought I'd already done, but maybe the flash of the firmware undoes that?)
Not sure where to go from here.

Very useful thanks a lot
Currently firing up FreeXperia CM9....fingers crossed.....
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
