Hello,
I'm currently running Slim CM ROM on my Xperia U, Unlocked Bootloader.
I was wondering, I made a nandroid backup now & I want to install & test other roms like JB. If i have to return to this current state of my slim cm rom, is it possible? With all the apps, data in place?
& I've heard that on whichever version of CWM recovery we make a nandroid backup, we have to restore it using the same version. Is it true?
Here's my scenario:
I want to test PAC man ROM 4.1.2, I'd be changing the kernel (with it the CWM recovery's version changes), say i didn't like the rom, now i'll fastboot the slim cm kernel & now I enter CWM recovery & press restore. Will it restore everything including my apps, data, the way i left it before installing other rom?
Yes it backups the WHOLE SYSTEM means you xan experiment on roms and stuff provided you don't lose cwm

Hey i just unlocked the bootloader of my xperia s. it is rooted with cwm recovery. i flashed advanced ics kernel with xtxperiance rom using cwm. but now i want to return back to stock. i created a nandroid backup before flashing the kernel and rom and i already flahed it several times after installing mods but now it is not restoring back. it gives an error of restoring boot image. i also restored after unlocking the bootloader so i think its because of the new ics advanced kernel. please help how to i return to stock kernel or restore my backup? i really need to restore the backup. cant clean wipe everything.
thanks
hi friends..
i have sony lww rooted and a flashed custom rom serenity v3 and vegeyance 1.31 kernel.
now i want to try another custom rom but i have some confusion..
should i have to follow all procedure again while flashing another custom rom
i mean i don't want to loose my data and contacts again i have backup but i don't want to do it again
so if i want to flash another custom rom should i have to follow all procedure like..
-flash a kernel
- do a full wipe/factory reset
- wipe cache
- go to mount & storage>format system
- go to advance-wipe dalvik cache
- flash the rom
i know flashing kernel and flashing rom is always important and without it i cant install any custom rom
but i hate the steps to follow between these two steps.....
so friends plz tell me is this compulsory to follow all steps or is there any short way...
thanx to all in advance.....

If you are on an ics kernel, no need to flash a kernel again. If you want to flash CM, then you have to follow all the instructions. While switching between roms, wipe everything except the /data partition. Then install your new custom rom. There is no guarantee that the rom will boot. It is recommended to wipe everything but no harm in trying. It is much safer to backup contacts by going to contacts and export to sd card. For messages you can use Sms backup and restore on market. Use titanium backup for apps. Done!

I would not recommend to format /system. Otherwise you may get a getprop error. The updater-script should wipe /system automatically
Only wipe it if it's recommend in the thread of the rom :good:
follow this procedure bro...
1.Backup
So you dont want to lose data...then first backup your contacts,export it to memory card,
then backup messages using sms backup and restore,u can find that on the play store...
dont forget to make a nandroid backup..
2.Gather info about current device status and the rom u want to flash
then check whether the rom you want to flash requires a different kernel other than the one on your device right now...
if the android versions differ,definitely kernel has to be changed otherwise you can get stuck in a bootloop...
visit the rom thread,check whether there are some bugs associated with your device,download the fixes required if any...
here you might find links to the supported kernels,instructions on installing the rom i.e wipe cache,data,dalvik cache,system etc etc...
download the rom,copy it to your sdcard along with the fixes if any...
3.Start flashing
First flash the kernel...then enter recovery
wipe the partitions that were mentioned on the thread...
then select your rom and flash it..,then enter recovery again if u want to flash the fixes...
4.Restoring..
install titanium backup first,restore all your apps from the nandroid backup,then you can restore the contacts and messages...
you are done
i know its a long procedure,u can get really frustrated until you hit on a stable rom and kernel...but i dont think there is any shortcut to this..
Sometimes the updater-script in your new rom may have been set to delete data,system,cache,dalvik cache. So if u don't want them to delete u have to edit the updater-script.
if i backup my current rom using CWM and i flash new rom and i dont like it or i get bootloop, if i go into cwm recovery and restore my backup rom will i have the exact rom as in all apps installed/ updated and all configurations the same as when i made the backup rom?

Yes, i do think that is the whole point.
I recommend doing a alternative backup aswell, such as titanium or helium. And when restoring to your backed up rom, do a factory reset + wipe system.
Good luck!
You really need to read the guides/tutorials stickied in the General section based on that question.
Hi!
I need some help with understanding of flashing custom roms e.t.c.
If I have 4.3 ( latest official update ), is it possible that I upgrade to CM11 4.4? Or I just can flash roms wich are based on 4.3?
Dont get it!
Thank you for responding!
If you have custom recovery installed, then you can install Compatible ROMs for your device (such as CM 4.4). If you are running stock or another ROM, then by entering custom recovery and making Nandroid backup first, you can install the ROM. To install, read the post for ROM you want to make sure compatible/whats needed (like GApps, etc), download, backup current ROM if isssue happens (to save yourself), WIPE data/factory reset, WIPE cache/dalvik cache, install ROM/etc as directed via the ROM post page. As long as you can meet these, you can flash what you'd like.

Welcome, make sure you do your research though on flashing and the ROM in case there are issues with the ROM specifically (ex. Bluetooth not working, or something). Any one thing missing (didn't flash GApps, ROM problem, etc) can cause issue. If no issues or you can live around them if they exist, then good luck.
Hell guys!
I recently started flashing custom roms found in the rom section and I'm currently on latest pixel experience Build.
Next I want to flash custom kernels and see how it goes but since I'm fairly new to all this I want to make sure I'm doing it right.
1. So what's the safest way to switch different kernels while being on custom rom such as PE, lineage etc?
2. What's the procedure for flashing these custom kernels through twrp?
3. How to take backup of the current stock kernel that comes with this (PE) Rom and restore safely in case of bugs without losing previous apps/settings/data or causing bootloops, soft bricks etc?
Thank you for your time.
before you flash anything backup your Rom first
(by Boot data system vendor in custom recovery)
Do clean install by Wipe dalvik cache and cache and flash the kernel
Backup:
Backup /boot partition using twrp, this contains the currently installed kernel and ramdisk.
Installation:
Flash the kernel zip, no need to wipe anything.
Restore:
Restore the boot partition you made earlier in twrp.
If you don't have a backup, you can dirty flash your currently installed ROM, this will restore the roms stock kernel and also uninstall magisk which you can reflash.
