Question concerning backup before flashing cyanogenmod

Hey Guys,
I want to try out cyanogenmod 7.1 on my xperia play. I still have a locked bootloader but clockwordmod recovery is already installed, so if something goes wrong, i am able to go back to my stock 2.3.4 rom. I think for cyanogen mod working right, i have to flash the doomkernel too? So what will happen if i unlock the bootloader, flash a custom kernel and a custom Rom and then apply the backup, i created before? Will i go back to my stock rom, stock kernel etc? I cant find an answer for this :/ sorry for Bad english, im from germany

Despite the fact that you have recovery, you can't use cyanogenmod on a locked bootloader. Cyanogenmod requires a kernel that is different from stock, and you can't flash a kernel on a locked bootloader.

Yes, i know about that. My question is, if i unlock my bootloader, flash a custom kernel, Flash cyanogenmod and THEN use clockwordmod recovery to apply my nandroid Backup, that i createt, before unlocking the bootloader and flashing all These things, will this work? So im back at my stock rom and stock kernel? I really want to try out cyanogenmod, but i want the option to go back to stock, if something is Not the way, i imagined. And i dont know, if the kernel is included in a nandroidbackup. Furthermore, i dont know if a Backup, created with an locked bootloader will work on a device with an unlocked bootloader too?

Sorry, I guess I didn't read your post in its entirety.
The short of it is yes, you can use the nandroid of a locked on an unlocked phone. The nandroid won't backup nor restore the kernel, that must be flashed separately. The kernel is such a small filesize, and the command is easy enough that it shouldn't be a problem. That is, unless you wanted to change kernels while away from a computer.

Thank you, this was really helpful to me so i have to download the stock kernel, if i want everything as it was before cyanogenmod. But thats not the Problem, i guess. I think i'm going to try it out after work, thank you for your fast answers

I'm not entirely sure, but I don't believe there are any stock kernels available. You can use an .ftf file with flashtool, as that sets everything to stock, then restore a nandroid after reinstalling recovery.

Ahhh thats a lot easier than the way, i planned to do this. Thanks

If you restore a nandroid from a stock ROM after flashing the cyanogen kernel your phone won't boot.
You would need to go back to the stock kernel before restoring. Problem is, you don't have a recovery in the stock kernel.
You could revert using flashtool, by flashing stock, then rooting, then install the locked version cwm, then restore.
Or after unlocking the bootloader before even trying cyanogen, flash DooMKernel, and make a backup through the kernel recovery. Then you can try cwm, and if you don't like it, flash DooMKernel again and restore.

Flashing on locked 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 ?

Custom ROM 4.3 to. kitkat 4.4

I am running IOKP 4.3.1 on my nexus. I have downloaded the OTA update for kitkat 4.4. Can I flash the 4.4 update from cwm or so I have to return to stock then flash it? I ask this because my stock backup will not restore due to md5 mismatch. Thanks for any advice.

Anyone?

Just backup, restore a flash the 4.4 ROM.

OK I've backed up iokp. Can I now flash 4.4 from cwm? Or do I need to flash stoc first?

You can only flash an OTA if you are on stock ROM.

OK but how do I get back to stock ROM then? My backup won't restore.

If you don't know how to flash back to stock manually you are probably better off using one of the toolkits in the development forums.

Tasssadar has some stock flashable zips here:

Don't forget to thank him if you use it.

They seem to be stock kitkat. I would need to flash stock JB and then flash KK though, yeah?

No. Just wipe(cache, dalvik cache, data, and system) and then flash KK and you are done.
Another edit: Since you can't use a computer for this, you should download a few other ROMs so you have something else to flash if something goes wrong. I would really only recommend upgrading if you have access to a computer. Things can go wrong very easily. Good luck.

Thanks very much!

They aren't update custom ROMs, they're like factory images. You just need a kitkat 4.4 custom ROM that you can flash in custom recovery. If you don't have custom recovery on your tablet, you need to use your PC to flash it, or just boot temporarily.
Afterwards, restore your tablet, clear cache and dalvik cache, install zip, choose your custom rom, and flash it.
If there is an update for a ROM (such like nightlies for CM) you wouldn't have to restore the tablet, just flash the updated custom ROM because it's just an upgrade.

Trouble going back to JB from kitkat

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.

[Q] how to go back to stock rom or...

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
