[Q] Manually update to JB 4.1.2 (requirements - before & after) - Galaxy S II Q&A, Help & Troubleshooting

Dear all,
Im plannig to manually update to 4.1.2 my s2
Actually my s2 has:
base band version: I9100XXLQ6
kernel: Siyah-s2-v5.0.1+
Compilation number: IMM76D.XWLPZ
*#1234#
PDA: I9100XWLPZ
PHONE: I9100XXLQ6
CSC: I9100OXXLPV
Build sep 21 2012
Also i did a backup with cwm.
I did a backup because i can't found a stock rom with the same pda, phone and csc
Before install, i will not have any problem doing the manually update via ODIN ???
If the update is possible, after install can i restore my cwm backup and everything will be ok???
Thanks!!

If you restore your CWM backup, you'll be back on whatever version you backed up before you updated. It'll be like you didn't update at all.

@ctomgee are you sure that cwm backup ALL ?
After updating to JB how could i do the restore? CWM will be deleted after updating (i guess). I will have to install siyah kernel to JB ???
Thanks!!!

Yes. You should probably read some guides. This is a basic question that has been asked over and over and over and over and...... you get the point. Look in General at the stickies.

What restore? What are you trying to accomplish, exactly? are you trying to just upgrade to JB and retain all data/etc?

Do you mean you will no longer have CWM recovery after updating? If so, then yes, this is true. You will have the Samsung stock recovery image after updating, until you install a kernel that has a permanent CWM recovery image in it.

I don't even know what you're asking here. If you're asking if you have to install Siyah kernel before upgrading to JB, no, not necessarily. It might be a good idea if your phone has a eMMC chip susceptible to the brick bug, AND you're currently on a 4.0.4 firmware from Samsung. If either one of those conditions is NOT true, then you don't have to worry about it.

He asked if he'll have to flash siyah, as in mandatory.

You know my idea is:
backup all the information with CWM ( i did)
Update to 4.1.2 via ODIN (no yet)
After update to 4.1.2 and i dont like jb (or maybe i have a problem), i want to go back to 4.0.4 how can i restore my old backup???
The update will delete CWM? If the update delete CWM is possible to reinstall it?

Ok, this was NOT clear in your first post whatsoever.
Yes, if you update to 4.1.2, the update will remove CWM recovery. To restore your old 4.0.4 backup if you are dissatisfied with 4.1.2, you should:
- re-flash 4.0.4 via Odin
- then re-flash the same version of Siyah you had while you were on 4.0.4 previously (to get CWM recovery back)
- then boot to CWM recovery, and restore.
Then you should be back where you were before you updated.

Why would he need to flash 4.0.4 again via ODIN? Thats just a waste of time and not needed. He can simply flash Siyah in ODIN, reboot into recovery and flash his backup.

I suggested it for maximum compatibility, in case he doesn't boot into recovery. Chances are good he would boot loop in that scenario, and it takes (wastes) just a minute or so.

There a manual to how to restore a cwm backup with odin?

You found no results because you can't do what you're asking for. Odin flashes .tar packages. CWM backups are not .tar packages.

[Q] Updating to KG5 via kies from 2.3.3 KF2

hello, i recently bought a SGS2 and i was just wondering, if i use kies to update the current XXKF2 kernel to the new KG5 one (also jumps from 2.3.3 to 2.3.4 right?) will this process factory reset my phone? will i get to keep my current layout of apps and cellular operator settings or is it all gone?
oh, i forgot, is there an insecure KG5 kernel yet to root with?
Hi! I really dont know if it will reset the phone but if its just the kernel it should no change it. I would recommend you to do a nandroid backup (google) with clockwork. There should be an insecure kernel, after the backup update it. Then root it go into clockwork - advanced restore and restore ONLY DATA. This should work.
Note: if you need the insecure kernel please tell me the build version i'll provide a link.
Sent from my GT-I9100
Kies does not update a kernel its a full firmware update .
Kies updates do not normally wipe the phone but you should have a backup .
jje
Scratch that, kies is being stupid and wont connect to the server so i cant update this way anymore, but i guess i can still use odin, im just not sure what kernels to use for the update and what kernels to use for the root, there are so many threads about this, im just getting more and more confused lol.
im currently running:
baseband:XXKF2
Kernel:XXKF2
Build:XXKF2
i'd like to update to the latest root-able firmware,
so if you can provide me with the link need i will appreciate it,
from what i gathered i need to flash the updated stock files, then flash the insecure files, the reflash the updated stock to remove the yellow warning sign, i think.
thanks.

And yes, you're right. Backup, stock firmware flash, restore data, root kernel flash and stock kernel flash.
If you are doing this with odin your data will be wiped so a backup is needed.

[Q] Switching between version with ClockworkMod Recovery

I currently have stock GB version 2.3.5. I plan to flash CF-Root kernel with ClockworkMod Recovery and flash ICS. If I make backup of my current version will I be able to revert to it once I install ICS? Or will flashing ICS flash a kernel which is incompatible with GB?
Yes if i make a backup of 2.3.5 i can flash a ICS rom and from there even if i flash a custom recovery for ICS i can still restore my 2.3.5 backup its "universal"

So will I need to flash another recovery after flashing ICS or will ClockworkMod Recovery still be there?
Clockworkmod will still be there no matter what 2.3 or 4.0 rom you use just that every rom tend to have their own "themed" version of cwm. but they all still backup and restore the same way. Just a note, for the SII the recovery is part of the boot.img (had to get this in my head the first time as my old phone was different

I'm not 100% sure what that means so do I need to take some extra steps because of it?
Erm if you dont know what it means then its ok (it was meant for those that has prior experince)
Just to add, if you go stock using Odin, cwm won't be there until you flash cfroot or similar.

Rommanager , CWM on SGS2

Hello XDA-community,
I've rooted my Samsung Galaxy S2.
Model : GT-L9100
Android version : 4.0.3
Baseband : L9100XXLPW
Kernelversion : 3.0.15-L9100XWLPD-CL524746 [email protected] #3
Build : IML74K.XWLPD
I've read that I could get CWM on my phone by installing ROMmanager.
When I go in ROMmanager and use the option to install CWM.
It freezes around 95% , the app stops and give the option to quit rommanager.
After restarting Rommanager I see that i have "succesfully"installed CWM , but when I click on the start recovery my phone Freezes which only stops by pulling the battery.
What should I do to get CWM running.
There is a halve CWM on my phone , which I don't know how to remove.
And how do I get a working CWM since I need it for installing ROMS.
Also I dont trust ROMmanager atm so is there another app which could flash a rom , or is there a way to fix the rommanager?

Run away from ROM manager, it's not fully compatible with our phone.
You need ROOT access inorder to get CWM recovery.
Visit this THREAD for the safest rooting method
then flash this Siyah or Speedmod via CWM recovery in order to have a permanent CWM recovery (optional)

I am following the guide that you send me.
I've installed the CWM , but when I continue CWM blinks for a second resetting to the first option.
I have still acces to my phone or whatéver
I've found out that using the volume buttons makes it reset , but the touch screen works.
Now im backing up my phone and install root files.
But i get a message no sd-ex found and can't install the rooting file

@Jokesy - Just a quick info..Even i did a backup using CWM backup and it was successful. I am on stock ICS 4.0.3 XWLP7.
I think the phone would get bricked if you try backup using CWM on a phone that has stock ICS 4.0.4. Correct me if i am wrong here.

You are partially right.
**If you're trying to do a ROM backup in CWM recovery**
1. Yes, the phone will be bricked if you are running stock ICS 4.0.4 ROM with stock/stock-based kernel
2. No, even if you 1. is applicable to you but you have a sane emmc chip.
-The only reason why I don't want people to risk it even after confirming their emmc chip is sane, is because I want them to be 100% safe.
I'll juststop here because Other points might lead to greater confusion.

[Q] KIES firmware update has nobbled my SGS2. How to fix?

I downloaded a 4.0.4 LPW firmware update via Samsung KIES today and upgraded to that from my previous 4.0.3 LP8 firmware (with a rooted kernel from http://forum.xda-developers.com/showthread.php?t=1103399). I realise now that this was apparently a big mistake because I immediately got a bunch of "unfortunately, XXX has stopped" error messages after rebooting. This includes an incessant "unfortunately, the process android.process.acore has stopped.
I have useed the emmc brickbug app to confirm i have some "insane" chip and the brick bug?
I read through the instructions at http://forum.xda-developers.com/showthread.php?t=1756242&highlight=emmc. Then I tried reverting to the previous LP8 firmware using Sammobile and Odin (including flashing a LP8 kernel to re-root), but I'm still geting those error messages, and my SGS2 is very(!) slow to respond.
I'm not sure how to move on from here.
Should I:
1. Keep flashing the LP8 kernel or firmware again and hope for a different outcome?
2. flash some kind of custom ROM?
3. wait for some other kind of firmware update from Samsung?
Grateful for any advice.
regards
Update: My phone is unsable now with the constant "has stopped" errors. I'm going to try the 4.0.4 update through Kies again and report back.
Update2: Second update via Kies to 4.0.4 seems to have removed most of those error messages. It's at least usable now. However I want to root and when I look at the kernel verison I see "3.0.15-1056084 [email protected] #3 SMP PREEMPT Wed Aug 22 22:55:24 KST 2012." It doesn't say "LPW" or anyhting similar to help me identify a rooted kernel to download to gain root accesss. I'll have to investigate other rooting options (downloading a rooted kernel was the only method I was familiar with).
Download the latest Siyah kernel (tar) and flash via Odin. You will get root access.
Here is the link for the latest Siyah v4.1.5
http://www.gokhanmoral.com/gm/2012/09/08/siyahkernel-s2-v4-1/
And also in the meanwhile don't do anything on the stock kernel, you run the risk of bricking your phone.

You need to wipe data / factory reset or at least wipe dalvik cache. You can do this safely from cwm of custom kernel (Siyah will be the best) or 4.0.3 stock kernel.
Don't do any wipes on stock 4.0.4 kernel with modified recovery if your emmc chip is known as insane.

It wont Give You Errors, i think...

Yes, don't do any wipes before if your current kernel is stock 4.0.4.

Make sure you DON'T wipe data/factory reset in the stock recovery in 4.0.4. Immediately flash Siyah Kernel or Dorimanx through Odin to remove the MMC_ERASE_CAP which causes nasty bricks if you wipe in stock 4.0.4. Then you can wipe in Siyah Kernel CWM and flash a custom 4.0.4 ROM or 4.1 ROM of your choice.

You need to clear your cache partition, do it twice for good measure.
That solved my stopped messages after updating with Kies, be careful as the guys above have said. Flash another kernel then do it.

This should do,

2) Install Siyah Kernel (latest: http://www.gokhanmoral.com/?p=1536) using Odin (tar file)
3) Now you are rooted with Siyah Kernel and a CWM based recovery
4) You can then install any ROM/Kernel of your choice (if you need)

My story and f-up:
After rooting with odin i decided to install a rom "Jelly King" It failed with error code: 7. After rebooting it returned to stock ics thankfully.
I now have a wifi issue where i cant connect, it just hangs at "obtaining ip address", I since fixed this by assigning an ip address using WiFi Manager by Kostya Vasilyev.
Now is where i need the help...... Should i be installing a rom and kernel? or is there a all in one i should be looking for?
I'm looking for a rom as close to stock look as possible, i just want to overclock it a little and customize the battery icons etc. any suggestions?
You first need to flash a custom kernel via Odin to have ROOT and CWM recovery access, and also to avoid the infamous brick bug.
