WaveBackup - usefull Tool for Backup and more

I want to introducing new Tool for Backup.
More features are under development.
At the moment tested and confimed devices are only S8500.
To support S8530 or the other bada handsets, we need please feedback.
It has Beta stadium at the moment. Please visit this site for Download:

Thank you very much mortara.

I thank you for the greeting Mortara tool but the tool where ...

Download please here:

After Registration you see subforum of WaveBackup.
You can test this Tool if you wish.
Best Regards

@addfree: Thanx for the link. I have downloaded it. i will test when i will get back from my work. Thanx again.
Things are getting wonderful for wave and bada. first social hub premium and now backup tool.

Nice app, and something new after sTune (little outdated now).
Waiting for more options in mod, edit sytem files easy
and for full access too all sector in memory.

Yay, I can finally post in this section now
Thanks for posting about this adfree. Nice to see we'll have another method of getting into our phones apart from sTune. sTune was a great little tool, but sadly hasn't been updated in quite awhile.

nice job!

Does you have the apps that can run backup on Bada WaveII and can use restore on Wave II also ?

@ joolawan
At the moment under development. Beta stadium.
Generally S8500 = S8530... if sTune work for you, then also WaveBackup would do this.
But Rumours say. That on higher Firmware S8530 not more work with sTune...
NO idea. I have no S8530 to test.
If you can, please post result if sTune work with your S8530.
Thanx in advance.
Best Regards
Edit:
XXJKA for S8530 is told as incompatible with sTune... not sure, not confirmed and no idea what concrete not work...

Any news about WaveBackup ??
BC it is too quiet here

Can you browse the Osp/Applications folder with the fileexplorer part of wavebackup?

how to restore the apps back to the phone after the back ups? anyone tried this thing after flashing?is it working? or only the back up thing?

Currently, WaveBackup can only be used to backup App-Settings and data. To restore these after a full flash, you have to use WaveBackup or sTune and copy the files manually to your phone. I will enable the automatic restore sometome, but currently i'm very short of free time, and this is not top priority for me.

Sorry for giving this thread a bump. What is the manual process for restoring the apps back? Which files do I need to copy?

Try Flashing the Stock Firmware with ODIN. Search for the Stock Firmware Thread in XDA. If you tried that and it didn't work, you may have to take it to the Service Centre....Here's a tutorial you could find help from--http://forum.xda-developers.com/showthread.php?t=1640668

Friend, I know you'd prefer CWM as you are a New User...Believe me, I too preferred CWM sometime ago..I bricked my phone atleast three times using CWM before I succesfully installed Merruk 2.5 Deluxe using ODIN(on first attempt)..you just follow the tutorial carefully.You'll get it done for sure..READ THIS AT FIRST-- http://forum.xda-developers.com/showthread.php?t=1640668
There's the ODIN section..Go through it and you'll find it much simpler...I did. Good Luck..!

here u go .try this at your own risk.
Procedure to install Stock ROM in Samsung Galaxy Y GT-5360
1.First download the zip file (link https://hotfile.com/dl/164864526/e7ba5c1/clockworkmod.zip.html) in your computer,extract it. After extracting you will get a folder with three files i.e. Backup, Desktop.jpg, Thumbs.db. and then with the help of USB cable connect the Galaxy Y with computer to place the three files i.e. Backup, Desktop.jpg, Thumbs.db right away in the SD card inside clockworkmod folder. Do not place in any subfolder.
2.Detach the cable
3.Just check that in the backup files there is a folder DDLE1 and in that there is Nandroid.rsf.tar, System.rfs.tar, Cache.rfs.tar etc. if these are missing then again continue the process from beginning.
4.Now its time to turn off the Y to boot into Clockworkmod recovery by pressing the Volume Up key, Home and then power button together. In case you have install the creed ROM then press the power button and select the Clockwork Mod to boot the same.
5.Now wipe data and cache partition. After this select Backup & restore-> Restore-> DDLE1->Confirm-restore DDLE1 and wait for 10 minutes to flash the ROM.
6.When the installation is finished, select ‘Reboot system now’.
If this doesn’t work then you have use odin way.
PLZ PRESS THANKS

I hate to see the people getting their basics wrong and doing it all complicated.
1) First of all, DONT use Creed six ROM, its NOT an official one(not by creed series OP pratyush.creed), its outdated, way better ROMs out there now. Try USSRv8/ Jelly Blast/ Hyperion, they are way better than Creeds Six in every way.
2) Use only XDA posts/ROMs/Kernels to get the correct info, dont rely on 3rd party websites. If you cant find something in xda, you cant find anywhere!
3) Im assuming you are installing Merruk Kernel 2.5 (deluxe #206 kernel) which only supports overclock.
The error code you are getting there is due to the ext4 flashing. Merruk #206 involves the conversion of system,data and cache to ext4 and flashing the kernel in ext4, its a ALL-IN-ONE pack.
To get a perfect combo of flashing merruk dev #206 follow these steps:
1) Flash back to stock ROM (Refer to doky73 thread in development)
2) Flash any custom ROM you desire via CWM( Refer its thread for instructions)
3) Download and copy the latest merruk kernel package(#206 deluxe all-in-one pack) to SD card
4) Backup your ROM using nandroid backup option from CWM
5) Flash the merruk kernel zip via CWM
6) Now, Go to advanced restore in CWM and restore data,system, cache
7) Reboot..
Thats it, your phone is now installed with latest merruk kernel(which involves the overclocking capability).

its mean here is not any solution of real [Q] how to fix error status 7 in samsung galaxy y
we all know about odin packages on XDA...
i think here is cygwin software issue....... its not for all
or
is this solution?
extract the boot.img and flash it via fastboot. Then perform a Full Wipe and try to flash the ROM again....
An unlocked bootloader is recommend for flashing custom Roms and kernels.
i think its solution..

There is a prob in ur updater script

Modem crash has been occured (LG Optimus L7) (Update info added)

Hi.
EDIT: Update Info added at the end of the page.
I hope someone will be able to help me.
First I apologize if this question already exist, but I'm too tired, and I hope there won't be a lot of grammar errors.
My brother had some error with LG Optimus L7 saying "Modem crash has been occured".
But first more details.
As I said:
LG Optimus L7 is what he is using.
He have few apps installed: sofascore, avg, viber, WhatsApp - I will be able to write full list of apps later this day.
Yesterday he update it to newest version of android - "Android 4.2, Jelly Bean"
There wasn't any problem for the whole day;
And then in the morning something happened with the phone.
And this message was on the phone - And since the picture I had taken with another phone is little doubled I hope I will write what does the error says correctly :
-----------------------------------------------------------------------------------------------------
Modem crash has been occured
Please do following action
Capture this screen
Get ramdump file from "OPBT" (I think) - Memory Debug App Tool
Send email to (I think it says) [email protected]
-----------------------------------------------------------------------------------------------------
ERR crash log report, Version 2. - Does this mean that there was also another crash......if yes, did phone restart itself then.....and is it possible to restart itself.
Error in file NV (I think), line 0
Time of crash.... some time - 3 a.m.
Now it says something I can't read.....
Build ID: PF00-M722FA-V20a-MAR-08-2013-XX - something like this.
REX-TOB ptr: 0x2?4f6300 ?-means something
tCD: task_name: DOO
Register values from nex (I think) core:
And now there is ~15 more or less "errors" which I can't read, but they say this I think:
ARM_SWC_R0 : 0x0A0A0A0A
ARM_SWC_R0 : 0x000000000
.........
ARM_SWC_R10 or RT0 : can't read.
ARM_SWC_R10 or RT0 : can't read.
ARM_SWC_R12 or RT2 : can't read.
More likely it is R12 and R10.
........
What else I can read:
ARM_JVH_SPSR : 0x00000000
....... - means that Error repeat itself or I can't read it so I can't write it
And it is possible that SWC is actually SVC
Above is on the left column, and this is on the right one:
ARM_SVC_R1 : 0x00000000
ARM_SVC_R3 : 0x00000000
ARM_SVC_R5 : 0x00000000
ARM_SVC_R7 : 0x00000000
ARM_SVC_R9 : 0x00000000
ARM_SVC_R11 : 0x00000000
ARM_SVC_CP (I think) : 0x00000000
.........
ARM_CPSR : 0x00000000

Also - the battery drained a lot, from 70% (12:30 am - 8 a.m.) to 10%, even more.
Also, it is a new Phone, 1 week old, so it is still under warranty if this is some bigger problem.
Thank You for your help, hope someone knows what could be the problem, any advice appreciated.
Should we worry about this.
EDIT: Update Info:
It seems that "we" needed to "restart" the phone after we update it. (Since the phone restarted itself after the update we didn't think about that then)
And that Notice we didn't saw anywhere till yesterday on some forum.
After that day, after phone crash error has appeared - ALL works perfectly since then.
All improvements by Update you can really notice, especially about battery, battery drain is a lot slower with this new update.
So, I could say that the problem is solved. If one day repeat itself, I will be back.
Thank YOU!
Best Regards
