which is the latest gb ?
i now that is 2.3.6 but which is the lateset update from 2.3.6 ?

search for XWLA4 in that thread
and download it,
stock kernel also there seperately , just download and keep no need to flash kernel,

Check samfirmware for a full list of available firmwares and versions.

Is it safe and doable to do a downgrade from ICS to GB then? I' like to reset the binary counter, don't have time for a usb jig to arrive so I thought would go ahead with the Triangle away app. Currently running on GB 2.3.5.

Why don't you flash with cwm? Then u don't have to worry about the triangle~~

[Q] Can I flash old bootloader on stock ICS?

I flashed stock ICS 4.0.3. LPQ through ODIN and flashed CF-root. Now I would like to remove yellow triangle and flash counter with USB jig which I have here. I was reading about USB jig wont reset flash counter if stock ICS is flashed because of new bootloader. Can I flash old bootloader to make USB jig working? I have done that on stock 2.3.5 firmware and USB jig has done his job well but can I do the same on stock ICS now? Can I brick my sgs2 with that? Thanks!

since your on ics now, no need for jig. Just use triangle away to remove yellow triangle and counter.

yes it is if you know this...
1: your on ics bootloader
2: checked download mode and know what the counter says.
If triangle away says differently don't forward. Otherwise yes.
I'V done multiple times.
well, if bootloader updates with new ROM then I'm on ICS bootloader and flash counter is on 1 at this moment cause I've reset it before with jig whrn I was on 2.3.5 rom

[Q] Q about triangle away !!

Hi there

Android version

baseband version
I9100xxkp8
Kernal version
[email protected]#3
Build number
IML74K
I think it is a stock rom but i don't like it cuz face recognization doesn't work , i can't connect my device to pc as a mass storage , the bluetooth visibility is only 2 minuets and other problems , so i decided to go back to stock rom Gingerbread 2.3.5 , but when i knew about Triangle away apk i though about take this chance and use it to reset my counter to 0 cuz now am still on ICS and this apk doesn't work on GB but before that i want to ask u does it work on my current rom ?!!!
NOTE : my device is rooted with CWM
any advices can u give it to me about using this apk ?!!
Thanks a lot
developer's advice is not enough? http://forum.xda-developers.com/showthread.php?t=1494114
what is your binaray count now?
how did you flash ICS rom XXKP8( old unofficial leaked version)? if you have flashed from CWM, trangle away will not work, since you have old GB bootloader.

by flashing ICS from ODIN, you have already ICS bootloader, and as already instructed above use Triangle away....
follow the instructions of dev too
To clear up any misconception, ICS boot loaders are NOT required for Triangle Away to work. You just need to be on ICS. Member oinkylicious documented using the app with Gingerbread boot loaders just fine.
Thanks for the information, i was awaiting for clearing this doubt...
That T-away works regardles of the BL
Yup, I get the nice kick in the........ To get this info corrected lol.

[Q] Were can i find the original ICS bootloader

Hi there,
I am using ICS 4.0.3, i have a USB JIG and i want to use it to reset the flash counter and get rid of the pesky triangle.
From what i found on the website i understand that i will have to flash the ‘old’ gingerbread bootloader to get the JIG working with ICS.
I am using this ICS rom I9100XWLP7_I9100XXLPS_I9100XENLP3.
I have two questions
1) Will the ‘old’ gingerbread bootloader work with the above mentioned rom?
2) Were can i find the original ICS bootloader to bring my phone to its initial state in case i need to claim guarantee.
Thanks in advance for your answer
Greetz Henk
Just use triangle away app to get rid of counter and triangle on ics.

Usb jig is working with this rom GT-I9100_FOP_I9100XWLP7_I9100OXXLPH_I9100XXLPS. I want to update to dxlp9 and root with CF-Root but i can't reset the counter. On that xwlp7 the jig is working (personally tested).

3.flash ics(if you want it) and to root it without increasing the counter follow method 2 from here: http://forum.xda-developers.com/showthread.php?t=1679778

hey neerajganga
you said triangle away worked, the reason i said it was not tested and highly dangerous was because no one even tried on i9100g so thats why.my question is this will it work with i9100g with rootbox ics with cm based kernel?
also eng.mohamed851
are you in ics or gb because triangle away works only for ics.
Triangle Away does not work on I9100g.. It says MAGIC HEADER NOT FOUND.
May be we need to request its developer to make it compatible with I9100G also..

How to install old bootloader and reset counter?
I have a Galaxy s2 GT-I9100 and unsuccessfully attempted to root the phone and the counter is on 5.
Current state of the phone is that it can only access download mode.
Tried a jig, that didn't work. Next tried to install old bootloader using Odin this also failed.
Initially the phone was running ICS and I believe I must have attempted to install an incompatible root kernel.
My intention was to reset the binary counter and then use Kies to restore the original firmware.
Any assistance would be appreciated.

Pull out your battery and CONFIRM what is says for the model number of your phone. This will confirm or deny that you have the i777 Samsung Galaxy S2.
IF it has a model number of i727 which is also, kind of, sort of, a ATT samsung galaxy s2 but is considered the " Skyrocket". So PLEASE before going any further check it out before you get flamed here if you get help and you don't have the i777.

I was on stock ICS. I wanted to root.
Then i flashed the siyah kernel, after that the phone booted with just samsung logo
I tried flashing a stock rom but it fails, it just halts. However installing a kernel through odin is successful.
Even kies fails to install the stock rom, it downloads the firmware but nothing installs.

Trying to gain root via installing another custom kernel is NOT the way to go, in fact, it's not the right way and AFAIK, it's not gonna work.
So, it was stock ICS and you want to .......... what? just root? or intend to install a custom firmware?
Either case,
FIRSTLY, rooting. Read the stickies, there are links to instructions how to root (per ROM version)
SECONDLY, in order to install custom firmware easily, strongly recommend installing CwMR first. HOW?
a. make sure it's rooted.
b. install Mobile Odin
c. flash custom kernel which includes CwMR. Be careful of flashing GB kernel to GB firmware and so on.
So go back, a question for you.
How did you manage to install Siyah kernel first place?

Siyah kernel was in tar format can be installed in desktop odin. Am I wrong?
the bottom line is now I cant flash any rom through odin or kies. It just hangs at the start. I am able to install stand alone stock kernels through odin without any problems. I guess I am clear aout what I am talking. Help appreciated. Thanks

getting a jig to reset the counter and will try to get a replacement.
It turned out to be bad cable issue.
I brought a new micro USB cable and the rom flashed nicely
May be if kernel flash ok but not rom, one needs to change the cable. :laugh:
