none of these ROMs are doing a TOTAL wipe though. Every one i've flashed so far, I've still got the same screen unlock PIN as my stock OS....

 

[nakagusukumike]

anybody got a SC02COMKF2 baseband that I can flash? hahahaha

 

[R3wt3d]

Yay

I'm getting mine tomorrow.

You guys seen this ROM at http://armalitexyz.jp/?

seems to be r3wt3d kernel.

don't touch that unless you've got something to ODIN back to hahahaha. BTW, if you get the red warning screen that you had a bad firmware upgrade, just ODIN right from that screen...

can someone who hasn't messed their phone up yet (still running the docomo ROM) rip your system with dd in ADB and post the files?

Are you sure that the placement of files is the same between the 02b and the c

no. probably different. perhaps a directory listing of block devices would reveal something intuitive? Let me check mine and try to dd them to SD and see what the sizes are.

 

[nakagusukumike]

They are, in fact, not the same.

Wonder which block device it is. Maybe just infer based on what the resulting file sizes are and which one is 7 or 16 MBish.

I bought mine two days ago, and only this morning did I realized that there is a retractable antenna that is used for the SEG TV. Have you tried deploying it?

yeah, there is an antenna. 1seg App won't even attempt to tune. It's totally different behavior in the app after flashing a kernel with root.



... I've got a feeling the baseband is /dev/block/mmcblk0p8. I'm about to revert to a friends...

 

[gaikokujin]

the gs2 is my first android and I would like to root it but after reading your posts it is freaking me out.
How do I rip my system and make a total baseband back up? is the basic back up app enough?
I was thinking of using lite ning rom, do you think it would be safe for the SC02?
Thanks

 

[nakagusukumike]

hold off for a few days till I figure this out

if you care about your TV, GPS and strong signal. hahaha

 

[nakagusukumike]

i'll have an answer for you in an hour or two on if you can install a root kernel and keep your GPS.

As of right now, what I've gathered is: you install a root kernel, you loose your TV for sure.

Install a full rom and loose your base band and your GPS is borked too.

My buddy is coming over my house right now and I'm gonna try to dump his good binaries and inject them into my phone. I'll let you know how it goes...

 

[gaikokujin]

thanks! I have not even put my music on the phone yet. I will wait a bit!

I need root to do that don't I?

 

[nakagusukumike]

you need a root kernel to do it with a terminal on your phone, not sure if you need to have a rooted phone to do it with ADB from the Android SDK or not.

I was literally minutes away from rooting when I saw this thread. Thanks for your insight -- hopefully you get this figured out. I don't care about the TV, but I'd love to return to using my root required apps and custom roms without breaking everything else.

I'm 100% stock still -- I can't manipulate and hack away code myself, but I can follow directions and type out command line stuff if you want me to try and get something from the phone.

 

[evildave_666]

This will really all become moot the first time there's a carrier update and we can download/extract the files from off the Kies server. Then we'll have good PDA/Baseband files so we can always go back barring a total brick.

 

[nakagusukumike]

For sure!

So is there ANY good way to make a bit level backup of this device without having a root kernel installed?

obviously dd won't work on block devices without root. :-(

 

[nakagusukumike]

hopefully I can get this GPS thing worked out. Just waiting on anyone with a working GPS on an SC02C to send me dd dumps of their 2 through 6 partitions...

dd if=/dev/block/mmcblk0p2 of=/mnt/sdcard/mmcblk0p2.img
