Trying to get away from 4.0.4

Hey,

I want to get away from the 4.0.4 firmware so that I have no fear doing wipe/factory reset when flashing another custom rom ..

I've followed the steps for downgrading it, but I'm not sure with performing a data/wipe reset.

I've already flashed a "safe" kernel (siyah) and as a noob I'm still afraid of the still existing insane chip.

Please help :S
[Galaxy S II General] egps2:
If you have Siyah kernel then you should be ok! Many people have reported wiping with no issues with Siyah because the brick bug is disabled :) if the brick bug is the only reason you wan't to move back from 4.0.4 then I would not worry too much but otherwise you could simply flash back a 4.0.3 rom as per front page instructions:
[Galaxy S II General] AsukaVol2:
okay :) and can i just take any stock firmware? i mean if i flash for example gingerbread it will change the kernel to stock again or?
[Galaxy S II General] egps2:
Usually should be ok but sometimes you can run into trouble flashing much older firmware versions like GB! I would recommend a stable 4.0.3 rom like LPS/Q as there should be less problems downgrading! And yes flashing the rom via odin will replace Siyah with the stock kernel but make sure you keep Siyah for as long as you have a 4.0.4 rom. The latest stable 4.0.4 rom is I9100UHLPS which, along with many others, can be found on this thread: http://xdaforums.com/showthread.php?t=1544487 :)

Good luck and remember you should be ok with 4.0.4 (I have been for as long as Siyah has had it fixed!) the latest 4.0.4 roms like LQ3 are very smooth!
[Galaxy S II General] AsukaVol2:
Wuuh, it works! I have 4.0.3 again! Thank you! :D

Now I get slowly the idea how this works :'D

Well I think i will flash cyanogenmod10 later. I did stuff like that on a htc before but after i heard that you can hardbrick a galaxy s2 i was afraid of it.

But as you say the only problem is the stock kernel.

So, thank you again for your response! :)
[Galaxy S II General] egps2:
I'm happy to help and I'm glad you got it working without going all the way back to gingerbread! You can safely flash between 4.0.3 roms if you need to but try and stick to the most recent versions :) some are also compatible with the popular JKay mods. I know it can be very confusing when you first start but at least you're safe now! Ps you can also use Siyah kernel with these roms as it has other features than simply just disabling brick bug but it's not necessary and stock works fine too :)

Have a nice day!

Another solution (tested earlier today):

I had an 4.0.4 stock rom (BULPG) with root (SuperSU) but definetly with eMMC brickbug (tested with Chainfire's app). Flashed Philz kernel (v2.7 for 4.0.4) and got CWMR v6 + brickbug FREE!. After that you are free to install anything you want.

Running the latest PACman ROM at the moment. :)

Just wondering if the emmc bug is actually cos of a fault on the mobo all people living in Europe would still covered under warranty by Samsung... even if you accidentally data/cache wipe your phone

Still a fault in the phone

Ive done it on my previous phone...

Just take the phone to a Samsung service centre... let them check the build date if it less than 2 years... Under the eu jurisdiction... Samsung must repair your phone without charge

my phone got no harm

As long as you are flashing using odin you will be fine..It only bricks your phone if you try to wipe on 4.04 stock kernel in recovery..I was a victim of superbrick bug. Samsung replaced my motherboard to recover my s2.:p

Hey Guys,

I was thinking of buying back my i9100 and then I just found this thread.

I thought i9100 was free from this, and now it has the risk of eMMC bug too?

I'm so mad! :mad::mad::mad: I don't know who to be mad at. (my dumb luck, samsung, exynos, 4.0.4. It certainly is not XDA's fault, they're just telling me the truth that is hard for me to accept) AHHHH!

It's scary enough to flash new roms that I scare myself into re-read instructions a bizillion times but now I have a good chance of hard bricking my phone with eMMC bug.

Other Android phones don't have hard brick bug!?!!

[Galaxy S II General] jarruz:
First you should try to take out battery and wait for a while. Then try to enter into DOWNLOAD mode and flash again the same firmware. If this is a one file 4.0.4 or 4.0.3 rom don't use a pit file, no repartition option checked and whole rom file should be placed in pda. If something goes wrong, flash some gingerbread rom (3 file) placing all parts of rom in proper places with proper pit file and repartition checked. It must work:) In case of troubles go priv.

Hi everyone a friend of mine owns galaxy s2 he is on stock ICS 4.0.4 phone info

is it possible to downgrade to offical 4.0.3 using odin without changing his kernel i mean keep everything stock then use odin to flash the downgraded firmware

Many Thanks
[Galaxy S II General] leolysenko:
It is possible to downgrade. If you flash 1 file firmware the phone wont start so you ll have to enter recovery and do a wipe /factory reset. Or just flash a 3file firmware.

Of course all the data (contacts, applications, settings) will be erased.

Hi guys

I need an answer please

I bought a new Galaxy S2 for a friends. Now this phone have stock 4.0.3 with stock kernel.

I want to put 4.0.4 with speed mode kernel.

I check with emmc check and phone have sane chip... brick bug problem. (0X19)

Question is: If I put latest 4.0.4 with Odin, then speedmode kernel with Odin I will brick my phone ?

Thanks
[Galaxy S II General] Sun90:
As long as the 'emmc brick bug' app say's u have a 'sane chip', ur safe ma8:)

But still not taking a chance if i would be u, would not wipe anything in the stock recovery and would flash the speedmod kernel immediately after configure of the phone, to be on the safer side:)

So 'Odin flash of stock 4.0.4 firmware, then configure ur phone and after the same flash Speedmod kernel from odin will not cause any harm:)

If you wish to downgrade then I suggest you to flash a safe kernel like Siyah or Dorimanx. Then u can even flash the stock firmware even from applications>CWM. If you place the stock firmware on your phone's SD card. Using ODIN will increase your counter by one

If you are having I9100 then download Siyah v5.0.5 (not CWM version) kernel from gokhanmoral.com and flash it via ODIN. If you dont know how to use ODIN then search in other threads.

Just wish I had seen this before I fried my cousins phone. Had successfully flashed a friends s2 days earlier and all was fine. I think because that one was on gingerbread and I flashed cf root in odin.

Anyway, after rooting (exynos abuse) and installing cwm recovery (cf root XW_NEE_LPY v5.6 via mobile odin), I was flashing latest omega jb rom without wipe and it sat on 'formatting system' for a few minutes then it just turned off. Not a single sign of life (jig, 3 buttons, charger, pc). His phone was originally on stock 4.0.4 Vodafone Australia rom.

Having flashed thousands of times (kernals, roms, modems etc) on S1, 2 & 3 I never ever thought this could happen. Unfortunately since upgrading to the S3 I wasnt aware of these issues that arose with 4.0.4 on the S2.

I am trying to help a friend upgrade his phone,

It's a Samsung GT-I9100 baseband version XXLQ6 on android 4.0.4 and it has the insane bug so i'm a bit reluctant to proceed with rooting it.

It was upgraded to 4.0.4. without any root or anything installed except what was upgraded OTA with the original samsung firmware.

The only thing we we want to accomplish with rooting it is to clear the battery stats for a recalibration of the battery; is this possible to do this in any other way?

You can safely flash official firmware using Odin. If you want to install a LS8 custom rom you have to flash siyah kernel V5.0.1 using Odin. It will give you root and CWM recovery. Then you can boot into recovery , wipe data and install any rom you want to
