[Q] Update without loosing data? - Galaxy S II Q&A, Help & Troubleshooting

Maybe there is already an answer to this, have been searching for a while.
And my phone has been off for 4-5 months but i wanna try again.
Its softbrick, boot loops but i have cwm 5.0.2.3 that i installed after that happend.
The thing is that i dont wanna lose my data so im wondering if its possible to update the firmware without loosing data?
and where can i get the 4.0 ics or atleast earlier versionens as a file to download then put in the memorycard ?
regards
edit: is there a way to backup everything atleast with cwm? i know there is backup and restore but i think that didnt backuped everything last time a tried.

Check out any of the custom rom threads, or if you want stock, check out intratech's thread, flash it and your bootloop will be gone. Good luck.
Edit: No, there's only the backup/restore option.

[Q] CWM restore problem...

Hey
I was on GingerReal1.4, and wanted to try out overclocking on CM7. Made a backup on CWM and then installed CM7, tried, happy and decided to go back.
Now when I try to restore the backup, most of my apps arent being detected and the launcher is back to touchwiz and I can't seem to find superuser also. I assumed this maybe because sd-ext is not being detected. So I tried installing a2sd-gui from my titanium backup, that seems to work and isn't showing me any problem. I also tried reinstalling the kernel, didn't work.
And Ive tried restoring about 5 times till now, same result.
Am I doing something wrong?? Any help would be rly rly awesome...
Thanks

Did you format all partitions in CWM before restoring ?

Tried that, didn't work.
Even apps that were preinstalled on the ROM like ext4manager and Gmail are missing!!!
Thanks a lot guys
Then logically the problem is in that backup.
yea, that's what I'm thinking, though I did not get any errors while doing the backup.
I read about someone else having a similar issue a long tym back in the galaxy s forum, and i dont see any suggestions or solutions there.
Anyway, given up for now, will take care of it some other tym...
Backing up all i got and switching to CM now.
Do let me know if something pop's up and you remember this issue of mine.
Thanks again
No.. The backup is not the problem. I have read somewhere that the problem lies with the bootloader.
When you upgrade to CM 7, it uses the 2.3.7 bootloader. And now you are trying to restore a backup associated with a 2.3.4 bootloader. The restore does not contain the bootloader. Thus you may experience a bootloop.
The only get around is to flash via odin.
Hit thanks if i helped.

What do you mean when you say you cant root anymore because you have CWM? Rooting and CWM are on separate tracks in this case, CWM does not stop you from rooting your phone. Are you saying you dont want to root?
Also, rooting is very simple, just change your kernel to cf-root(to be flashed via CWM, check http://forum.xda-developers.com/showthread.php?t=1158197 ) and you get added advantages like ext4, BLN, a2sd support etc.
PS: Read all you can before doing anything

Corrupted Root - How do i restart again?

hi guys,
i've tried looking for a solution, but have not found one.
After rooting, installing roms, themes etc, i have come to the conclusion, that my rooted s2 has become corrupt i.e. (either kernel or rom). The reason i know is that i have a fault with CWM and that is it won't detect sd cards. I have now tried 3 different microsd cards and none can be mounted, even though it shows "sd card mounted". Yet when i try to install a .zip file, nothing is found.
Rather than wasting time trying to figure out what the problem is, i'd like to restart ALL OVER again. That means actually getting the phone un-rooted, back to stock and then re-root and install custom roms again.
My question is how do i restart all over again?
If you can, boot into download mode and flash stock firmware with Odin.

thanks aiancalandorn, but that will NOT wipe the phone...i need total wipe...how do i go about doing that?

Sounds more likely that you're using CWM recovery incorrectly.

thanks for ur advice guys. For now, i have managed to setup checkrom+dk with ics 1.6 theme. i stopped using the phone last night approx 12 midnight - 100% fully charged. I've woken up and checked it at 10:45am....battery shows 99%, so thats hardly anything.
The only issue i have noticed with checkrom/dk is that there is a lag when pressing buttons or scrolling through applications...what do you guys recommend to fix this without putting a big drain on the battery?

Get my phone ready for new ROM

Hello guys.
What is the best way to wipe my phone, so its completely ready for new ROM?
Sorry if its alrdy out there. But hopefully you can help, im a bit new.
There area couple of things I would do and they are as follows
1. Do a backup of all your apps with Titanium or some other program like that
2. Do a full Nandroid back up of your current rom just incase you soft brick your phone.
3. Back up your EFS folder once that is gone its pretty hard to get it back. I have never had a problem but others have.
4. Make sure you wipe your cache/user data with CWM and also dalvik cache. This is to insure you dont have any issues with your old rom conflicting with the new one its sucks I have done this even if it says NO-WIPE rom.
5. Install your new rom whatever that may be

In addition to the steps, you can also format the system and emmc, If you want a clean slate. Just remember to place New ROM and nandroid backup on ext SD card before formatting
I was a bit hasty when flashing, and did not get a original rom backup(nandroid). Am I completely ****ed now? My current rom works just fine, just wondering if my next flash softbricks it. Could I back up my current rom and return to that?
Also, if I flash a original sammy rom from the original rom thread(the one I presume my phone came with), will I be able to update through the built in sammy function(Search for updates)?
Sorry for hijacking, but this thread seemed suitable rather than starting a new.
Cheers!

Sure, any backup of a working ROM is good. You can always pull an official firmware from Intratech's thread to flash back to stock if you need to in the future.

Maybe. I see a Norwegian flag in your profile. If you flash back to stock, it MAY work for you. Doesn't for me, but that's because I'm in the US, and no one officially carries this phone here.. so neither Kies nor OTA work for updates for me.

No, not suitable at all.
Hijacking bigtime and not using "search" either - good start, you'll not be popular if you carry on like this...
Since like me you're in Norway and can't sleep either I'll try to help - no links though, you gotta search:
If you're careful with flashing the softbrick chances are small. Yes, you can back up your current ROM.
No, you can't update via "search for updates" on the phone. It's an OTA feature that's never been implemented in Gingerbread - at least not here in Norge.
And you can't "presume" what your original firmware/ROM was - you either know it or you don't.
To be honest, you don't sound like you're ready for custom ROMs yet. I'd do a lot more reading here if I were you.
Lykke til.

That does a full wipe, whilst keeping root.
If you change Roms, you will lose your root.
But when you install a custom kernel, most auto root anyway.
Finally words of advice, ALWAYS be sure what your doing if flashing anything!
Don't rush into Anything until YOU KNOW what your doing.
Not sure about something, ask. (dont guess or assume)

You need a custom recovery to flash roms such as cm7. It is also used to make a backup of your phone and wipe the data on your phone. How is it that you've flash cm7 (which means that you've also used your recovery before) yet you don't know the purpose of having a recovery? I think you're going way to ahead of yourself.
Sent from my LG-P509 using xda premium
I'm guessing it's more of a case of he's flashed cm7, using the recovery to do so, but doesn't understand the behind-the-scenes procedures that go into the actual flashing.
you need to read the sticky thread if you dont know basics
Think of custom recovery as the basic setup/installer tool for anything and everything related to custom ROMs, kernels, etc. .
kdz and lgdrm are only for stock(OEM)/official releases.
The reason you need it, because it's the only way to do it and carrier's don't give you access to change your ROM. Does Microsoft put mod chips/software in xbox 360? No, hell no, they only give you limited access and regulate what content can be yours.
Custom recoveries come with features that you normally can't do, like nand(full phone backup) backup.
It's this way because that's how it has to be done.

Just because your phone is "rooted" dosent mean you can install a rom like a app, you need to use clockwork mod, why do you need it? you need it because it allows you to perform actions that you couldn't do on a stock phone. With clockwork mod you can back up your system files, restore system files, install new roms for use or testing. If your phone is just "rooted" all it means is you can now access system files, use certain "root required" apps, being rooted is step #1 to installing clockwork mod, its like your phone is unlocked, if you just want your phone rooted to delete some system apps thats fine, but it is wise to flash clockwork mod because it can prevent your phone from being bricked and now you can install roms. so the answer is pretty simple, how else would you install a rom without clockwordmod? you couldnt so its just one of those things you need, hope this helps man
reply
apart from all this custom roms come packed as zip files n kdz updater or lgdrm doesnt recognize these files so u need to hace custom recoveries like cmw or twrp or amonra

I don't think that you could do that... since the phone doesn't even come with CM7 in the first place. Doing a factory reset / restore wouldnt bring the phone to stock CM7. Correct me if I'm wrong but wouldn't it bring the phone back to FroYo since that's what it came with?
CM7 is already a custom ROM so there is nothing stock about it... Stock means whatever the phone came with from the box (FroYo) CM7 is Gingerbread.

If your running cm7 or any rom you can do a factory/reset through the rom your using, it will just erase all info but wont delete the rom and it will delete apps so when you reboot you will have to set up Google account like a new phone, cm7 will still be installed and your current rom it will just be like new, to do a factory reset go to settings, security then hit factory reset, reboot and then back to a clean start on cm7 there will be a option to erase everything on the SD card, hit no if you want to keep all files on your SD or hit yes if you want it all gone, goodluck p.s the only way you can go back to stock is to flash a stock rom and if you made a backup of your stock rom before you flashed cm7

I really dont see a point in doing so if you plan to upgrade to ICS.
If you're experiencing problems, you should do it all once again, flash .42 or .58, root it, upgrade it to ICS, install CWM and back it up (nandroid backup), with all the bloatware and everything... just in case... afterwards, start modding, delete bloatware and do whatever you want. In case you screw something up, you can always return to stock rooted ICS (that you backed up) and try again
When i installed ICS i flashed .42 and then i upgraded to ICS... so not even .58 and certainly not .62; it seemed a bit cleaner not to upgrade to higher GB version before upgrading to ICS, since if i wanted to keep root on ICS, i wouldnt be able to erase user data.
Reinstall ROM.
