Reflashing rom - AT&T Samsung Galaxy S II SGH-I777

hi, i have a noob question, i dont know so much about repartitioning and other things, my question is, when upgrading a rom it does at normal procces (wipe data and install zip) . im taljking about for example ,i'm now in shostock 3 , it is android 4.1 and if i would back to cm9 , could i do that?. i have a nandroid backup of cm9, can i just restore this backup and i wont have problems without matter the rom i'm coming?, sorry for my english and thanks for the understanding.:good:

I'm not familiar with CM9, but the only issue would be if the ClockworkMod Recovery in the SHOstock3 kernel is compatible with the backup made with thebackup made with CM9. I'm thinking it might not be because the Jebo kernel in SHOstock3 backs up a pre-load partition.

Do You think then that is better flash again cm9 instead of the backup?

nandroids have never backed-up kernels i dont think
i was guna say kernel flasher
you on cm7 or miui or a normal GB rom ??
theres only like 3 kernels for normal GB roms so could just download one and keep it on your sd, could maybe do the same for cm7 or miui but i know nothing about them though so dont know

Nandroid have never backed up kernel on our Samsung phones when using a Samsung rom. But had we had the partition layout like we have in CM7 based ron's, it backs up the kernel just fine. But you can't just go and restore a nandroid of CM7 any old time, you must be running CM7 based rom first.

or if something doesnt work out for you, just reflash the rom without wiping...it will load the kernel on there for you...

There are UCKH7 and UCKK6 stock kernels floating around. No need to back them up, they're out there already.

[Q] switching from rage kernel to x-kernel

hello people, this is probably the noobest question in the world ever but is it possible to switch from rage kernel to x-kernel without factory reset or anything.
its been a while i didnt play around with custom roms and kernels and make me forgot how to do so.
im currently using a rage kernel with stock .62 gingerbread. i found out my battery drains too fast. not sure if kernel problems or batterry problems.
now i want to test out other kernel which is this http://forum.xda-developers.com/showthread.php?t=1451150 X-kernel. hoping for it to give a better battery life than rage kernel gb.
so how to do this process again?
im too busy to check out the tutorial somewhere here. **** me, right?

Do a nandroid backup using clockworkmod before flashing xkernel . Flash the xkernel . If you lose data then restore the nandroid backup which you created before while you were using rage kernel.
I don't think you'll lose your data but it's always a good thing to do a nandroid backup. You don't know when you'll need it .

No, x kernel should be prerooted, too. Just flash it, it should work. But doing a nandroid backup first is a good idea, just to be on the safe side

No you won't lose root. Xkernel is a prerooted kernel.

flashing a stock rom with odin on custom rom with dorimanx

Hi,
I downloaded a stock rom from sammobile ( I9100XWLQ2_I9100XXLQ6_I9100PROLP4_HOME.tar.md5 )
I am pretty sure this is the right one because this has already worked once.
But now my phone hangs during startup. I wait really lot (10 mins) but still it hangs, even I always see the animation of 'S'
I flashed again a custom rom now, but i want a stock rom back. How can i flash?
thanks
You must perform a factory reset from the recovery. Either do it from the custom rom, then flash stock ROM, or flash stock rom, boot into recovery and then wipe /data. Order doesn't matter.

After you flash the stock rom go back into download and flash v4 of Siyah kernel (.tar) , then boot into recovery and do wipe/factory reset.
It is not necessary to install a new kernel, just factory reset from stock recovery

I didnt say it was necessary, I just advised it since Siyah kernel is better then stock anyway for many reasons and since he's into trying new roms its much better to have custom kernel/recovery. Plus the fact that if user was to try flashing a 4.0.3 rom then wipe in stock recovery he would brick his device.
Not sure about brick, AFAIK brick occurs with 4.0.4. Anyway I would prefer more stock-ish kernel like CFroot.

If you thought that, why on earth would you advise him to wipe in stock recovery???? The rom he is trying to flash is 4.0.4
Guess I wasn't reading thoroughly .. I take mt words back.

If u r on stock 4.0.4 first change your kernel then try to factory reset.. Everything will be fine... Dont do factory reset on cmw on stock kernel...

Okay, thanks for all the replies. When I flash stock kernel, will clockworkmod be erased? I am just asking.. I know I can easily flash it back

Do you mean flash "stock rom"? Yes if you flash stock rom you will lose cwm and only hav stock recovery.
Once you have flashed your stock rom you should then immediately flash your custom kernel (Like Siyah). Once flashed reboot into recovery (cwm) and wipe data/factory reset.

When flashing a stock ROM (include kernel of course) it overwrite the exists kernel.
Sent from my GT-I9100 using xda app-developers app
When you will flash stock rom over custom rom everything will be erased if android version is different if same then you will face problems has phone will not work properly you have to factory reset it first install different kernel use philz it will root your phone directly and installs cmw then factory reset it from cmw.
You can also reset your phone from settings but in between you will face errors this that not working etc. use 1st method your phone will not have brick bug issue.
And for giving thanks use thank button

[Q] CWM deleted, no Boot, paranoid android, siyah kernel

hi guys,
i tried to flash paranoid android, latest version. everything worked fine. after that i flashed gapps and the newest siyah kernel.
After that, my S3 shows only the s3 text and then nothing. The biggest problem is that the cwm is gone. But i can go to the standard download mode.
I need help to get the device running again...
I tried the following:
- flashed the stock kernel via odin to get back cwm - no sucess
- flashed the stock fw - no sucess - hangs now at the samsung text
Thanks in advance
flash the tar version of your recovery of choice through Odin. or format data from the stock recovery.
either way, it's only because you don't read. siyah doesn't support 4.2
R: [Q] CWM deleted, no Boot, paranoid android, siyah kernel
I believe before flashing gapps, if you booted up the phone, youre supppsed to wipe the cache: did you do that? If you did your gapps package might be broken or the kernel (check its the s3 version, which is a smaller version than the s2 one).
Try redownloading and reflashing everything (except paranoid android, if you know i does work when the phone starts up...)

what are you talking about? he said he doesn't have CWM anymore, so he needs to flash a custom recovery first through Odin.
and again, read my reply, his issue was that he didn't read - Siyah DOES NOT support 4.2

Thanks for the reply. Thats right, i have read it afterwards
I already tried to flash a recovery through odin. after flashing the device is rebooting. Then i have to remove battery because it hangs again. After That CWM isnĀ“t installed at all. Maybe you can give me a Link of an other version?
How do i format data from stock revovery?

Philz recovery is cool but can we be sure it will last? Is it worth keeping a recocery like that or wait for clockwork to get smarter?

But how do we know philz (if thats his name) will keep updating his recovery? Wouldnt it be safer to stick with clockworkmod?
Sent from my GT-I9300 using xda app-developers app
you still don't know what spamming is, do you?
then don't use any custom ROMs, because how do you know the dev will keep updating it? makes no sense whatsoever, stop confusing people
R: [Q] CWM deleted, no Boot, paranoid android, siyah kernel
That's not at all the same thing...custom roms change from one to another but a recovery needs to be solid, the thing holding all of your stuff together in the safest way possible. Of course i could trust a rom developer, but since android updates oftenly i will probably change rom just as often...not the same for recovery. Recovery needs to stay put, solid, stable, updated and trustworthy.
How can i know this philz guy wont make any new versions of his recovery after a month to come, or how can i know if i choose to switch to clockworkmod again because philz stopped development the backups will still be compatible?

PhilZ recovery can make backups compatible with CWM and TWRP. You can change your recovery any time.
and good luck being on stock.
actually, having an updated rom is more important than an updated recovery. recovery just needs to backup and restore to be useful.
R: [Q] CWM deleted, no Boot, paranoid android, siyah kernel
Yeah but i dont wanna miss faster backups...if they update i might miss it...cause philz doesnt have its own rom manager app...even though i prefer it to cwm.
