how to backup your device

This may well be a very stupid question, but I'll ask it anyway: I'm currently still using an untouch Medion Skate, Is there a way to perform a full backup in case the phone needs to be returned to the Vendor? (for warranty reasons of course).

I know you can do backups and restores in ClockWorkMod, but the phone needs to be rooted so that's not the original state...

I'd like to know this option exists before flashing to a custom rom.

I allso have the medion and a few more people. And no one made a backup of there stock recovery. So we need to know first if its the same as the ZTE stock recovery.

There is allready a methode to go back to stock.

But i need to know what stock recovery you have. Are you familiar with ADB and things like that?

How are you going to do that? "fastboot boot <path-to-recovery.img>". Does not work for me.

I have no idea yet, are you implying that a backup cannot be made?

No i am implying that im a noob :D and i have allready made a backup here: LINK But it does not have the original recovery inside you you have to flash it afterwards. But im not sure if its the right one. Since its the recovery from the original ZTE skate.

I'm starting to understand the point you are making...

A backup of the recovery partition can only be made with ClockWorkMod, but during the install of ClockWorkMod the recovery partition is erased. Thus a backup of the recovery partition is impossible.

Is my summary correct?

Yes exactly, so you will have to make the backup externally. Booting into clockworkmod, while clockwork mod is on your computer instaid of your phone.

Or boot into stock recovery like i added a part to the noob proof tutorial. And give me info about the recovery partition:D

If the recovery is the same one as we pulled out of the ZTE stock rom. You could go ahead, if not we will need to dump it...

D3abL3 and me are allready trying to make a full stock backup but something whent wrong so it would be very kind of you to wait with flashing CWM. And try to help.

Okay I checked you thread, it's clear so if the commands work I should not have any problems. What info do you need from the recovery mode?

I think if it looks like this it will be ok.

Offcourse it wont say use trackball to highlight: click to select.

But it should be Android system recovery <3e>

I thought you guys have already got stock recovery for medion in this thread.

Since you have insecure boot.img from Sebastian404, you can use cat command to backup partitions. detail info could be found in http://android-dls.c...ack_Boot_Images

But if the boot.img is modified doesnt that allso create a incomplete backup? Or do you only have to dump the recovery.img? Because im pretty sure its the same one as the ZTE and D3abL3 allready made a flashable zip. The link is in my signature.

Allso do you might know the problem im having. from this >> #54 << post because i really want to fix it.

So I can replace the default recovery with ClockWorkMod and I'll be able to put the default recovery back later?

If you could flash the unsecture boot.img like xiaoyaoswim said you can make a full dump of the phone. With the wikipedia link, but i dont understand that at all :P But if your recover allso is "Android system recovery <3e>" like in the picture it should be good. But i would not take my word on that since im not that familiar with those things.

If you want to go trough with installing clockworkmod. Could you point out things i maybe forgot in the tutorial.

Ok. I've read most of your posts. I'm going to talk about my understanding on Sebastian404's suggestion.

You have probably already known how to flash the insecure boot.img into your phone. Once you got that you will have root privilege in ADB tool, then you will be able to dump every partition of the phone. If a untouched device is used, all stock ROMs except the boot partition could be backed up. Though the recovery partition of your medion phone is probably the same as a generic Skate, by this way you can backup exactly the original recovery.

Assuming you have Paul's ADB package for superboot/CWM, type the following commands in sequence:


adb-windows shell

su

cat /proc/mtd
In result you will find the partition structure of your device.
dev:    size   erasesize  name

mtd0: 00600000 00020000 "recovery"

mtd1: 00400000 00020000 "boot"

mtd2: 00180000 00020000 "splash"

mtd3: 00080000 00020000 "misc"

mtd4: 00200000 00020000 "cache"

mtd5: 08200000 00020000 "system"

mtd6: 13400000 00020000 "userdata"

mtd7: 00100000 00020000 "oem"

mtd8: 00180000 00020000 "persist"

Mine (OMC) is displayed as above. I think your medion one will likely be the same (The sizes will be different since I've re-partitioned my OMC). From this chart you will know mtd0 is recovery, mtd2 is splash and so on. If you continue to run the following command,
cat /dev/mtd/mtd2 >/sdcard/splash.img
you will then have a dumped splash.img in your MicroSD card. You can flash it back to your phone by fastboot in bootloader mode:
fastboot-windows flash splash splash.img

The dump and restore process is just the same for other partitions. As far as I know. you only need recovery, boot, splash, and system to restore full stock rom, others are user data or not important.

PS The first boot image of Skate is determined by splash.img, and the second one is in boot.img. So if you restore both splash.img and boot.img to stock medion you will get it full back.

PPS I would suspect that your battery-charging-icon problem was caused by splash.img too. Try to flash another splash.img to fix it.

Yea i finally understand it now but my device isnt untouched anymore so v1pEr will have to do it. If he knows how to do it. I would really appreciate it! If you allso speak dutch i could explain it to you better.

I tried flashing other splash screens. I dont get the battery logo back. I allways flash the splashes like the one in the medion topic. I dont know if there is anything wrong with the <name>.zip. It just has a folder instide called META-INF and splash.bmp. I tryed restoring to everything i got, tried installing new roms. Tried different splash screens, nothing seemed to work.

Have a try with a proper splash.img with fastboot flash splash splash.img

I tried my stock splash screen trough clockworkmod and ADB. I tried the green android ZTE stock splash screen. It does not work... :(

Do you maybe have some other idea's? I would really apriciate it :)

so has viper done it yet. itake it your mobile is kind of messed up .

I dont know, but i dont think if i am going to flash vipers backup is gona be any better... Because the backup i have is completly stock except the recovery.img This isnt the one that messed up the phone. And i really dont trust doing a TPT on the phone...

And i have no clue what caused it, i suppose it was the faulty backup...

v1pEr still didnt flash he's phone, so im in luck :D He is going to make the backup with the insecure boot.img. So the only thing he needs is the original boot.img? Wich i backed up right after installing clockworkmod. So if he replaces my boot.img with the one in the backup he made, we should have a complete backup.

Or am i missing something?

I sure hope this will fix my phone :P
