General :: How To Make Kernel Backup
Apr 8, 2012
recently one of my friends that have the same android phone than me (xperia x10 mini pro) try to update the system and he bricked the phone, after a some hours work i has able to fix the kernel using flashtool and one of the forum tutorials, but the off-line charging has not working, so a update the kernel and turns out pretty good. So i started to think about update my one, but before this i need to know if it's possible to make a kernel and boot loader backup, maybe without the system, to i be able to back in time just in case some think wrong happen.

I have a little experience using computers from late 1995 Year, and from year 2000 I am using also Linux from time to time, and very rare but it was a delight freeBSD. I have no experience on Android and MacOs.
Now, I all my family (father, mother, girlfriend and I) changed the phones on Android which is Linux based, but for ARM processors.
Anyway, I have played a little with Android 4 x86 on my laptop.From, my point of view, a Android Smartphone is just a little computer like an raspberry pi / pandaboard / beagle board.So, a mini computer with an Arm processor running a very small and tiny operating system max 8 Gb, when on my gentoo install I had been using about 30-40 Gb. I know, the size can be affected by the compiling flags but anyway.
Now, on all my system I had, from my experience I did 2 Backups, like this:
My laptop is backed-up on the External Hardisk number 1, and the External Hardisk number 1 is backed-up on the External Hardisk number 2.So, as it is a good practice to have a backup handy, I keep 2 backups in 2 different location in case of hardware failure / water flood etc. Some of the files I need are backed up in the cloud, on the internet.
I use to make IMAGES of the Operating System partition, and of the mbr , and of the partition table, with software like Acronis True Image, Paragon, DriveImage XML, Norton Ghost, Clone Zilla.
When I had to do data recovery I did an Acronis "sector-by-sector" approach image of the hardisk, and I recovered files from that image.
I assume that maybe I will need to get root on one or two phones, and one phone need's to be unlocked from the carrier.
Before doing this I would like to make a full backup of the phones.
1) How can I make a FULL backup of the android phones? In this moment my mother phone is a samsung galaxy mini2 Samsung Galaxy Mini 2 s6500 and mine is Sony Xperia L
2) a) If I will "unlock" the phone from the carrier (locked on orange, but i wish to use also Vodafone, I tim, I wind, moviestar, o2 etc)
b) If I will "root" the phone to gain administrator acces on it
After step A) and B) if I will restore the original backup, the phone will be "locked" back to Orange, and "un-rooted", or it will be "unlocked" and "un-rooted"?
3) Instead of having an hardisk like computer have, I guess the smartphone is using an "usb-stick/sd-card/ssdhdd"-like memory for storage of the operating system, so how can I see the partition table, the mbr, on the device?

I've been using android for a while now, and I actually can move smoothly througth the system. But now I want to update for the first time my firmware with a newer custom rom. And I have some doubts:
Usually all customs roms make you do the wipes. What what actually happens with that? I know what those directories have, but I guess the proccess only erases the apps and some configuration, right? Because I think some apps config are stored on the internal storage.
It is recommendable to make a backup of the folders to be wiped and then restore it? If it is, will the overall config be the same as before the rom change?

I search for a way, to make a complete backup. Because i will test some other roms. Complete backup mean somthing like the ftf files for Flashtool. a backup from kernel, rom and personal data's in one way with one file or folder that i can restore later. I think, that this not is possible with Smartphone on, so it must be a way with pc and Smartphone in Flash- or Fastboot mode?

Do most people always backup the ROM, w/ ROM manager before installing new kernels?
Also is there a way to set the number of backups you keep w/ ROM manager?

I have achieved rooting of my sprint hero cdma phone, but can not get to nandroid backup. i attempted to recovery reboot and it freezes at the htc screen, multiple times. i did luckily backup everything from my sd card and my apps/data before i did anything so i can get back to basics at least with root. i have formatted my sd card, and replaced it with everything that was on there directly after rooting. i can do a speedboot and see the menu to do the backup option, but i get the same results.

Is it possible to make a "backup" like the files that can be used to flash with Odin (phone, pda, bootloader and csc tar files)? That is, if I have a phone with some firmware I want to have in this format, how can I get it? I know about nandroid backup but that's a different format.

I am using My Backup Pro to backup my phone. While it does a good job it only does a selective backup. Is there a program that I can use on my stock phone to do a more comprehensive backup? Maybe a mirror backup like Nandroid?

So I've spent a fair amount of time reading all that I can about rooting before I actually decided to do it, but hit an unforeseen wall. I read about both the manual way and the instructional videos on youtube and decided to go with the videos. I rooted fine, and was in the process of doing a android backup with DroidRootHelper. So I downloaded and extracted the Tools folder and I thought everything was pretty straightforward until I realized that the instructions in this video

Whenever I try to make a backup using carbon it says I'd need to set the desktop backup password blank, but I already tried that a few times and it always gives me the same error. What do I need to do to make it work? I'm using an xperia s on ics.

The files in my TWRP backup folder are
data.ext4.win000
data.ext4.win001
data.ext4.win002
md5 for the above

I'd like to know if there's a way to use Titanium Backup to preform a backup and then transfer those backups to my computer ?
I know this may sound simple but am under the impression that when you make a backup of your ROM and other files on your device, it has to stay on the device.
When making a NANDROID backup, is it safer and more useful if one can store those backups on one's computer ?
Am sure there's a way to do this but am not sure if there's already an app for it.

I have titanium backup pro. I want to know can I backup only apps data? I mean when titanium backup pro performs backing up are there any option to excludes apk file backup and only backup apps data?
I think it's useless backup apk files, I can download them from Google play store.

I'm currently using Nikez Lente's ICS rom 1.0.1a9 and what is the system app name for the phone's homescreen where all my apps, widgets are currently stored. I'm a bit of a flash freak so every now and then I drag my at least 40-50 apps one by one.

where I have got right now on my phone, which is:
1. I updated to stock 2.1 using the sprint update tool.
2. I followed the video tutorial to root the phone
3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?
