[SOLVED] [Q] Downgrading i9100P to stock 2.3.6 please help - Galaxy S II Q&A, Help & Troubleshooting

Hi everybody,
I came here for help, as I need to revert back to 2.3.6 official stock firmware of an i9100P and so far all the tuturials that I have found only talk about i9100 version.
Currently I have installed on the phone:
Model Number GT-I9100
Version: 4.1.2
Base version: I9100XXLS8
Kernel Version:
3.0.31-889555
[email protected] #3
SMP PREEMPT Thu Jan 31 14:48:54
KST 2013
Nº of compilation: JZO54K.I9100XWLSD
After checking the back of the phone and going to Samsung firmwares I have discovered that the stock 2.3.6 is I9100PBVKL2_I9100PFTMKL3_FTM which I have already downloaded.
I have 2 questions for which I would kindly ask for your help. I have searched for 2 days, but I could not find reliable information as to how to do this. And because I don't want to end up with a brick I come here for help.
1st question:
How can I revert back to the stock 2.3.6 ROM? Can I just flash it with odin, or do I need a special files for i9100P version?
2nd question:
After I get to 2.3.6 what do I have to do to root it?
Thank you all for your help.

1. Simply flash stock firmware via Odin. No need of special files.
2. Root it by zergRush Exploit method.
One more thing - this is the general section. Please post questions in the Q & A Section.

1000 Thanks immortalneo
I would just like to ask if I need to select Re-partition in Odin or just leave Auto Reboot and F. Reset Time in the flashing options.
Sorry for the follow up question, but in some tuturials they use special pit files and csc files to revert back and I just want to be sure that I don't screw this up.
Edit: did you notice that the phone is actually a i9100P with a i9100 4.1.2 firmware installed?

Yes, I did notice that. But its ok.
Just don't change any options in Odin. Leave them at their default settings.
Do not tick 'Re-partition' or use a PIT file.
For more info, read about flashing via Odin.

Thank you I was able to revert back to 2.3.6 and now the phone is working correctly again. I had some problems with not registering to the network. Now for the root I am not sure why but it did not work out, It looks as if it did work, but after the reboot I still don't have su installed and all the options (usb debug. and install outside sources are checked).
I will try to update it to 4.0.3 official and see if that helps to get root.
If I can bother you with one last thing, do you know if there is a I9100P 4.1.2 stock,rooted ROM? Nothing fancy just something light, bloatware free and rooted with the latest JB features and a usable NFC chip.
Thanks once again for all your help.

There are currently no custom ROMs for I9100P. But you can install any custom ROM meant for the I9100!
Of course, you will lose NFC capability after that. To get back NFC, re-enable NFC using this patch.

Dear immortalneo,
Thanks for all your help. The reason why I wanted to revert back to 2.3.6 was because I had a problem with the phone not registering to the network. Everything worked perfectly on the phone, but the phone would refuse to register to the network. After trying different SIM cards I even thought that I had a blocked IMEI, but as soon as I reverted back to 2.3.6 the network started working again which probably means that the IMEI is fine. (please comment)
Then I upgraded to 4.0.3 stock ROM and I get the no network problem again (it even showed Safe Mode on the bottom left side of the screen of the phone), but as soon as I try to root it with your suggested program I get the the network working (after it rebooted).
What a strange problem. So now I have a the stock 4.0.3 (full of bloatware ROM) which I can't root with zerglings. I checked with root checker and I get the message "sorry your phone is not rooted".
The objective is to have a stable working 4.1.2.
Any suggestions?
EDIT: reverted back to 2.3.6 for root but still can't root the phone. Please see the print screen with the end result.

Ok, I get your frustration.
U need a debloated stock rom, right? Try NeatRom Lite.
But since it is for I9100, u will have to use NFC Enabler patch also.
That will do..

For rooting ICS, CF kernels or custom kernels are better than zergRush exploit method.
Just flash Siyah v5.0.1 kernel via Odin to get root on ICS 4.0.3.
Then you can flash NeatRom from CWM.

Sent from my SGS II

Thanks for the suggestion of the ROM. Downloading it now.
Now any idea how to install this on a stock 2.3.6 which I can't root? Any way to get CWM on it without root?
Please see the annexed image in my last post.
EDIT: Perfect will do what you have suggested, I'll let you know how it went.
EDIT2: Got it working as intended, registering to the network without any problems (so far), and very smooth ROM. The only thing I could not find was a way to add the Samsung Account (does not appear in the account options), as in case my mother looses the phone, the tracking and locking options will come useful.
But all in all it is working well (knock on wood).
Thanks once again for all your help.

Thanks once again for the advice. I used search instead, found out that the lite version had it removed, downloaded a zip file with all the removed APK, I have extracted it and installed just the one that I needed and problem was solved.
So if the question is there, I normally find it without the need of bothering people.
Thank you for all your assistance with the not so famous version of the GSII the i9100P . Hope to help you one day as much as you did help me.
Have a nice week.

there is no exact matching insecure kernel for ur firmware BVLPH so u can either choose the nearest one available that is BVLPD in link below

or u can simply downld the Tar version of Siyah kernel v4.1.5 or 5.0.1 (tar file for ODin) and flash the same thro ODIN to root ur device

Hi there thank you for the info. I have been to the site but there are two versions what is the difference between the original and the insecure versions?
Advice!
Hi,
I'm new to all this so not sure which insecure and secure kernels to use! Help would be fantastic.
My phones details are:
Model - gt-i9100
Version 4.0.4
Baseband version - I9100BVLPE
Kernel version - 3.0.15-I9100BVLPH-CL969772 [email protected] #3 smp preempt mon 30 jul 15:28:47kst 2012
Build IMM76D.BVLPH
Once rooted is there anything else I should remember to do/not do? I.e will any firmware updates via Kies overwrite anything etc?
Thanks

It could be because of all the flashing u did previously.
I dont know if it will solve your problem, but maybe u can try flashing a wipe script that will remove all unwanted files and prepare your phone for a new ROM...

On second thought, don't try that. That would require you to root and install CWM.
Have you tried doing a factory reset before and after flashing via Odin?

Isn't that method for ICS instead of JB? You can look for a guide that tells you the steps with Odin (in other words: flash a custom kernel with Odin to give you root access).

There is no custom kernel for stock official yet and as i know the root operation the same for all OS and devices right ?

Of course there is. Otherwise nobody could use rooted JB-roms. Look for Siyah for example.

Siyah is a custom kernel, but its good too. If you want to root with a stock based kernel, use Philz kernel.
U said u have I9100, right? Or is it I9100G?
Siyah doesn't work on I9100G.

That's a really big mistake mate! If you had done anything related to the I9100 on ur device, you would very well have bricked it!
Both have differences in hardware, and hence use different kernels and ROMs.

How to know which 4.1.2 update to use for phone from another country?

Hey Guys,
I've been searching internet for many hours now and I just can't find answer for my question.
Someone brought this phone over from UK, unlocked it, so it's carrier free and I bought this phone.
It has version 4.0.4
I heard that this phone can be updated to 4.1.2, which I've been wanting to do for quite some time now.
I understand that there are country specific updates, but I don't understand which one should I use?
I tried using Kies, but Kies is saying that I already have latest firmware version (although it's 4.0.4)
I would really want to update to 4.1.2, but I don't know which version to use in my case.
Do I need rooted phone to update it?
You dont need root to update to a stock firmware.
You can choose any country's firmware, it wont make a difference. Just make sure its an unbranded firmware.
If your phone does get locked after updating, simply unlock it after rooting.

Which guide/tutorial would you suggest using?
techzune.com/tutorial-how-to-upgrade-samsung-galaxy-s2-to-android-4-1-2-jelly-bean/ would this be ok?
I'm a bit unsure because each tutorial has different 4.1.2 update size

Since ur on 4.0.4, first I suggest you read about 'eMMC Brickbug' issue on 4.0.4.
Check it with the 'Got Brickbug?' app on XDA.
XDA is full of guides on how to flash a stock firmware. First try searching for it.
If u still cant find any guides:
1. Download a stock firmware from sammobile.com.
2. Download Odin.
3. Extract the firmware into a folder.
4. Put phone into Download mode and connect to PC.
5. Flash using Odin.
