Getting back 4.1.2 - Galaxy S II Q&A, Help & Troubleshooting

Hi to all,
I am newbee to android. After using HTC One V for few months I purchased Samsung Galaxy S2 GT-I9100 from UAE. It was running Jellybean 4.1.2 having Modem XXLS8. On a fine day for the requirement of built in call recording I rooted my phone and managed to install Omega Rom V23.
All went smooth. But next day I realised that Hindi fonts are not properly displaying and I made a big mistake to flash Omega Rom again. This time I stucked in BootLoop . Everything tried. Finally I gave up
I thought flashing back may work so I flashed available stock Gingerbird rom via odin. Now system is back running Stock Gingerbird Android with modem XXKI4. Then I tried to update GB to JB via OTA and Kies, But OTA and kies refused to update software.
Please give me any solution to get back my 4.1.2 version or tell me any idea to get Custom Rom Omega V23. Will it safe to flash Omega V23 4.1.2 directly on current 2.3.6 rom with Philz latest kernels?

Thanks. Can I root present 2.3.6 Gingerbird and Install Custom Rom Omega v23 4.1.2 directly? Or I have to reinstall stock version 4.1.2 over current 2.3.6 Gingerbird?

Well, the latest CMW version might be better, is not mandatory to go 4.1.2 tho.

I am not getting it. Please spoon feed me. I will be in debt.
I tried following steps:
I download Omega V23 custom rom and kernel - PhilZ-cwm6-XWLSN-OXX-4.93.6-signed and placed it on SDCard. After going into stock recovery I applied Philz Kernel via Stock Recovery. But getting error in red-
E:Failed to verify whole file signature
E:Signature verification failed
Please give me any solution. I dont have enough previlage to post into Android Development Forum as I am newbee here.

I guess you did not make backup of your original ROM... i would recommend that you install ics first before installing jb or custom jb roms... you can get stock ones samfilmware.. when try installing omega ROM again make sure you back your ROM this time so will not start all over again if a problem occurs at any time had same problem bootloop because of the kernel that was installed just did a full wipe fixed it for me and reinstall over again

Yepp..You are not getting it. System is running GingerBread with Stock Recovery. I can make backup in CWM recovery only. But right now my problem is that Philz Kernel is not installing. It will give me CWM Recovery and it will root the device. Any solution for above error??

[Q] Updating to a Jelly Bean Custom Rom

Hi there!
I am wanting to update my Samsung Galaxy GT-i9300 but am worried about the process because of having installed a custom kernel previously (would this muck up installing a new custom rom I wonder..)
Please find attached a screenshot of the settings and please tell me what I should do (if anything needs done) before I flash a new custom rom.
Cheers!
if you're worried about kernels, then just flash stock kernel then flash a custom rom on it.

kk, could you provide me with a suitable stock kernel (or links to one) which will be compatible with the rom I have installed?
any stock kernel that is for jb will be fine.

I am on android version 4.0.4 (so technically not JellyBean). and its safe to flash a stock kernel for JB despite being on that version before I flash a custom rom?
Sorry for asking, get confused easily..
you should be fine updating with a custom kernel (as all roms flash a kernel as well). Just make sure you factory reset when moving from ics to JB as you will most likely encounter problems if you don't.

I would suggest flashing ICS stock kernel first if you're worried. I thought you were already on jb.

Reflash the stock ics ROM
And flash any custom ROM you want

Error status code 7 when flashing ROMs usually means the install script failed an assert when trying to determine if you have the correct model of phone that the ROM is intended for.
Where did you download the copy of CM10.1 from? Are you sure that it is for your model of phone? According to your signature, you have an I9100. Are you sure you didn't download CM10.1 for I9100G, for example?

This is because your likley using Philz kernel for leaked JB.
To flash other custom roms you will need to change kernel back to a previous ICS or JB kernel like Siyah.
Flash the kernel (.tar version) via ODIN/Mobile ODIN.

Thx, I didn't know this about Philz... Mainly because I'm avoiding JB until Samsung releases an official version.

But I'm not using philz kernel, I never flashed it..
I just flashed this leaked firmware few days back.. That's it!!
Anyways, but most of them say to not use siyah kernel with cm 10.1... Rather use dorminax kernel with it, what you say about it?

Hey
Flash dorimanax but don't boot and then flash cm10.1

[Q] No Service! After flasing Paranoid Rom

No Service,After flashing Paranoid Rom.
I checked Baseband version.It shows Unknown.
So i flashed two 4.1.2 Baseband.But both did not work.
Then i flashed leaked JB 4.2.1 version ROM,Now All Service and Data Service working.
After that i rooted the stock rom and again i tried to flash PA rom.
This is also happening for CM rom.
But for other custom stock rom or temasek's UNOFFICIAL cm,it is working well.
Why?
Any solution?
I tried the same rom on another Galaxy S3.
Service was working well.
Mine and another s3 have same Baseband.
I did same steps to install for both headset.
Did you wipe your phone before installing the new rom?

I flashed stock rom.i tried to flash but no luck.
I think I need to completely reset my device.
For that do I need pit file?
Sent from my GT-I9300 using xda app-developers app
If you mess with Pit you are likely to have a brick .
Flash stock rom via Odin .

don't mess with PIT, just reflash another working CM rom (like slim) and it should be fine. THen if you want re flash stock, but you should be fine anyway.

help with basic rooting and flashing roms

hello all
i have a gs2 i9100
i rooted it folowing this guide short way (update from recovery)
http://forum.xda-developers.com/showthread.php?t=1994544
it installs cwm recovery 4.0.1.5 and supersu.
i tried installing a cm10.1 nightly version for my model,it allways abort with staus 7.
i tried different nightly version,no success.
then i folowed the official cm guide:
http://wiki.cyanogenmod.org/w/Install_CM_for_i9100
i flashed the zimage for cwm recovery via heimdall on linux,it went well then i booted into recovery to check and success.
i didnt want to flash cm at that point (middle of the day) so i rebooted the device and problem:
i could see the samssung boot logo with the yello triangle and then the screen goes black and..nothing.
for now i restored via recovery a backup i made on the older 4.0.1.5 recovery.
i also tried looking for a kernel that matches mine - jhls4 and couldnt find one nor a solution that solved the stsus 7 error.
what could be the problem?
That thread is so old now. More phone details. Firmware you have installed or had installed before you flashed cm? Model of i9100?
Phone model is gt-i9100
Im on stock tw jb 4.1.2
Never installed any other firmware just updated the official with kies.
I rooted it from the stock recovery-installed super user and recovery as update.
The rest is in my first post.
Appriciate your help.
Sent from my GT-I9100 using xda app-developers app
Flash it with philz kernel for root and custom kernel cwm recovery that will let you do anything. Philz is the easy way to root and install cwm to your i9100.
When that's install do the wipes and reboot.
Thanx for your reply
Q: any phils kernel or one that matches mine- jhls2?
2nd Q: can i flash the kenel via recovery ? Or just heimdall?
And if i flash a kernel do i have to flash a rom immedietly or can i still use the stock rom?
Total noob at this.
Sent from my GT-I9100 using xda app-developers app
Flash lss or lsw philz as its just the cwm that's updated in dif versions and yes this will work on your stock 4.1.2 no point in telling you to flash something that won't work on the ROM you have now then if you want to flash custom ROM you can do this from there. Either way is possible with philz . tar for Odin/hem and singed zip for stock recovery:thumbup: reading is the key to flashing well.
Thanx again
I read a lot and got a little confused.
Will do what u suggested.
Hope ill get it right this time.

Stock rom

Hi I've flashed my s2 with sentinel rom (basically cyanogenmod) so it's like a nexus 4 and I would quite like to flash a stock rom but not like the s2 rom like is there a way to flash an s3/s4 stock rom to my phone? :thumbup:
Sent from my GT-I9100 using xda app-developers app
No. Pls don't flash a rom that's not made for your phone as you will probably brick it. Look in Android development for what you want
I double dare you to try it.
Is there a way that I can go back to my original stock rom test it out and if I don't like it go back to my flashed rom?
Sent from my GT-I9100 using xda app-developers app
Hi,
Make a nandroid backup from you current rom und flash an other rom. If its not fit you can restore your backup
Maybe you have to flash the kernel that you used to make the backup before you restoring.
Basically I want jelly bean but the stock version. Currently I'm using a rom that is jelly beans but is like a nexus 4 but I want the Samsung features. Thanks
Sent from my GT-I9100 using xda app-developers app
Hi,
i know, you wrote on OP sentinal rom. Just make a backup from your current rom in the recovery. And then you go to the download modus and flash a stock rom via odin. If you dont like it, flash a recovery and restore your backup.
Easy
Ok! Where can I get the stock rom from and can it be jelly bean? I know that when you buy the new s2s they have 4.1.2 installed! And how to you flash a recovery? Everything else I know.
Sent from my GT-I9100 using xda app-developers app
Okay... do you flash the sentinel rom oder someone else? If you did it than you have to know what the recovery is. It the menue that comes up when you hold VolUp+Home+Power and boot. There ist an option "Backup and restore".
Here http://www.sammobile.com/firmwares/ you can get the official stock roms, just search for I9100. To download you have to register, its free
Andi
Get your stock rom from samfirmware. Just scroll down and download the required Android version. You can get temporary recovery from recovery tools in play store or if you want permanent recovery you gotta flash a custom kernel.
