zImage kernel

So I am a bit confused in step 3 it says:

3.In order to get to a working recovery, load the SGH-I777_ClockworkMod-Recovery_5.0.2.3. You'll need to untar this file to get to the zImage kernel file*.

so I unzip it and have extracted the zImage file. How do I load this. Which slot in Odin v1.85 do put it in?

Also, is it possible to use Odin to install the Siyah Kernel?

And if I format the sd card that will delete all the data that is there correct? Is this a necessary step?

Sorry to be such a noob.

Thanks

That did it. Now if I could only figure out why google play doesnt recognize my phone or account.

Thanks for all the help!
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Normally, a wipe data/factory reset from recovery will clear that. Since in your case it didn't, I would assume it has something to do with interaction with CyanogenMod. I have never used any of the CM firmwares, so I don't have any suggestions. You may be able to get some help in the one of the CM discussion threads.

Your signature indicates that your phone is a galaxy S3, and your side bar indicates that your carrier is *not* AT&T. These tools are for the AT&T Galaxy S2, sgh-i777. Flashing them on a different device could brick your phone.

Please find the forum for your device.

Hi, guys. I'm just trying to get my phone back to stock..not returning it or sending for repairs or anything so the flash count is irrelevant. But it appears that, just to do this process, I'd have to get that back to zero?

I did it anyway, and I got stuck in a bootloop. I rebooted into recovery, but my home button wasn't making anything happen.

Please help. I have a bricked damn phone and I'm going nuts. Can't afford to replace it off contract right now. I just bought a house!

My power button took a crap when I flashed ShoStock the other day. :( Did not have that problem before, so I was hoping that completely wiping my phone and starting over from scratch would fix that. The reason I flashed ShoStock to begin with was that I had been thinking of flashing a ROM anyway, but my phone was pretty flawless. Then it suddently started doing random reboots. I hoped a wipe and flashing a rom would fix it, but it did not. Then I flashed the Siyah kernel hoping that would fix the reboots in ShoStock, and it seemed to (was only playing with it an hour or two but the reboots usually were about every 2-3rd time I picked the phone up so i felt good about that. BUT...power button still was not working. A few other people had that problem with that rom so I wanted to try a different rom. That rom completely locked my phone up. So I've been trying to just put it back to stock and be done with it.

:(

Edit!! But I'm going to leave the original content just in case it's useful. I rebooted into recovery one more time to try it, and boom. Power button worked, phone rebooted just fine, and I appear to be back in action!!!!

THANK YOU THANK YOU THANK YOU for this thread!!!!!

Edit 2. As soon as I posted the first edit/update, it rebooted. So I guess I still have the rebooting issue, but I have a functional phone..good enough for now!

Strange issue:

Previously i use d kies to update to ics (i know kies is junk) and had sleep of death so i wanted to get back to stock.

First time i used I777UKH7 CL503881-NopBL it went without a hitch. Then used "I777UKH7 OCD Root No BL" (to root) and all was good. however, after trying to install a siyah kernel so i could over clock, my phone would boot to the samsung sII screen and stay there. (cannot remember witch kernel) so i tried to run "I777UKH7 CL503881-NopBL" to put the phone back and it fails every time. so i tried "I777UKH7 OCD Root No BL" and it woked "pass" and my phone works. but my problem is. i cannot use "I777UKH7 CL503881-NopBL" "fail" or kies. kies will fail after trying to update ginger to ics ( gets all the way to 98% every time) then says "un expected error and i need to use emergency recovery, and that does not work either. I cannot understand why I777UKH7 CL503881-NopBL fails but I777UKH7 OCD Root No BL passes?

flash counter is 0 and i can get my phone working, but its just weird.

any ideas?

thanks in advance.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
KH7 is 2.3.4 Gingerbread. If you tried to install the latest siyah kernel, it is for ICS and JB, but will not boot with a Gingerbread system. If that is the case, then I don't know what installing that kernel might have messed with that would cause one of the stock firmwares to fail to install. Having one package install but another similar package not install is outside my experience. Anyway, sounds like you have the phone working, but if the above is what happened, be careful about mixing kernels and systems.
[AT&T Samsung Galaxy S II SGH-I777] Cptnjarhead:
yes, i did install wrong kernel. Also, i found an older download on my pc, "I777UCKJH7 OCD No BL" file from 2011 and that works perfectly. Brings back to stock. I guess i should just leave it at that.

thanks for the reply.
[AT&T Samsung Galaxy S II SGH-I777] Kadin:
Quick question creepy, or anyone that can confirm, will this method work for someone who is on the latest version provided by AT&T directly through the phone updates? Sorry but I tried searching the best way I know how and can't quite confirm this. I see the OP was last updated in 7/12 so I'm not sure if much has changed since.

Help! Bricked my i777

I tried to install CWM 5.0.2.3 on my i777 with Odin 1.85 to root my device (regret it!), Odin said that it passed and my phone rebooted into the Samsung i9100 logo with a yellow triangle and wont boot android, i can enter recovery mode with CWM 5.0.2.3 working and download mode, binary says yes count:1

what can i do for it to boot? wipe data/factory reset? or get a jib first? please help!
[AT&T Samsung Galaxy S II SGH-I777] Alesis_neo:
Odin 3.07

Can I use Odin 3.07 to reset the flash counter or do i have to make a jig forcefully?

I can enter CWM recovery and download mode
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
First, I'm glad you posted in the forum. Seeking help through private message does not leave a record that can help others. Therefore, I usually don't give help through private messages.

What version of the firmware was on the phone? The kernel with CWM 5.0.2.3 is a Gingerbread kernel. If you have a later version of the firmware, either ICS or Jelly Bean, then it would not boot up. If you had Gingerbread on it to start with, then it should boot.

You can try entering CWM recovery 5.0.2.3 and perform a wipe data/factory reset. If the phone boots following that, then good. If not, you will need to enter download mode and use Odin3 v1.85 (preferred) to flash a full stock firmware. I would suggest that you flash UCMD8 which is Jelly Bean 4.1.2.

You can find all the resources you need in the Download Repository. See the link in my signature.

Flashing a custom kernel with Odin will trip the flash counter and cause the yellow warning triangle screen. Flashing a stock kernel will clear the yellow triangle screen, but will not reset the flash counter. You can reset the flash counter by using a USB jig, or by the application Triangle Away, but it is irrelevant at this point since the phone would be out of warranty anyway, so just leave it. Flashing back to stock as above will remove the warning triangle screen.
[AT&T Samsung Galaxy S II SGH-I777] Alesis_neo:
Thank you!!! :D

I got it working again by flashing the stock UCMD8 firmware on with Odin3 v1.85, I had 4.1.2 when i tried to put CWM 5.0.2.3, thats why it didnt boot before

Thank you very much for your help! :D

HELP

Hey Creepy, are you out there?

I was runner unnamed and wanted to flash back to stock. I followed your guide,

flashed the .tar and it completed successfully. But the phone did not boot all the way up at the end.

It shows a flashing battery...When I unplug the phone it goes into an endless boot loop.

If I could do a factory reset I think it would fix it, but I can't get to it.

Even when I try to boot into recovery (vol up + vol dwn + pwd) it won't go.

Can you please me?

The phone is SII I777

Thanks,

Neil
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
This doesn't make sense to me. Was the phone operating normally wlithout problems on unnamed? Also, what stock tar did you flash? The symptoms do not match the information given.
[AT&T Samsung Galaxy S II SGH-I777] tneil:
Creepy, thanks for the reply

The phone was operating without any problems on unnamed.

I first tried to flash I777UCKH7-CL503881-No-BL, which didn't work

Then I tried the one-click with StockKernel-PDA.tar which didn't work either :(

Sorry for the later reply, I didn't have access to the info until now.

Thanks,

Neil
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I don't understand why you can't get into recovery. Just flashing a stock firmware would not cause that to happen. You say that when you press the three buttons, "it won't go." What exactly happens when you try the three buttons to get into recovery?

I'm thinking maybe there could be some kind of hardware issue or failure. But at this point there's not enough information to tell anything for sure.

Assuming you can still get into download mode, the next thing you should try is to flash the full stock distribution, including boot loaders. I guess stick with UCKH7 for now. You can get the tar you need from the Download Repository. If that does not solve the problem, there are other things to try.
[AT&T Samsung Galaxy S II SGH-I777] tneil:
Actually, I'm holding two buttons (volume + power, this model does not have the hard home button)

until I see the Galaxy SII flash for the second time, and then let the buttons go. I does not boot into recovery,

it boots to the lock screen for 5 to 8 seconds and then the screen goes blank and the cycle begins again

boot to the lock screen, then screen goes blank...

I can boot into download mode.

I'll try to flash the full stock distribution
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
The correct button sequence for the SGH-I777 to enter recovery is to hold all three of volume up, volume down, and power. Try that, and then when you boot into stock 3e recovery, perform a wipe data/factory reset.
[AT&T Samsung Galaxy S II SGH-I777] tneil:
I tried the correct three buttons, it tries to go into recovery, it shows a faint, ghost image, but then it

goes into the loop.

I flashed the full package. It passed in odin, began to reboot, saw some yellow scrolling running half-way up the screen

and then it stopped and the looping started...

Thank you so much for your help Creepy,

Neil
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Try the following, just in case the problem is nand r/w corruption.

1)Go to this post and download the Tar version of Siyah 2.6.14 Kernel. Flash it in PDA without ticking Re-Partitioning. If you get a pass, it won't boot, so turn the phone off and then back to download mode and...

2) Flash the full stock Gingerbread distribution from the Download Repository, I777UCKH7 including the bootloaders and everything, in the PDA slot.

3) If you get a pass here, then the phone might boot, or you might have to boot into recovery first and perform a wipe data/factory reset. If you're able to boot the phone, then you are back in business, and can flash whatever firmware you want.

If it is not, then:

4) Download the SBL Bootloader from the Download Repository. Flash it as PDA in ODIN, without ticking Re-Partitioning.

5) Flash the Kernel, as in step 1.

6) Flash the full stock Gingerbread distribution, as in step 2.

(You can ignore the following for now, even though it could be true.)

If you are unable to get any of these to flash successfully, first you should assume a bad port, or bad cable, and try other ports, other cables, even another pc. If you can get no flash to succeed, then you may have damaged eMMC memory.

In case it is damaged memory, see this post from Mobile Tech Videos.

Before I start I have a question about step 2 & step 4.

So for step 2, I think the file is this

File:>> I777UCKH7-CL503881-Full.7z, from under this>> I777UCKH7-CL503881 Stock Binaries

Step 4

File >> i777 UCKH7 sbl.tar, from under this >> I777 UCKH7 secondary bootloader

I just want to make sure I grab the correct file...

Hi,

I have an i777 which i'm about to sell. I'm now running a PACMAN ROM nightly. The phone is also unlcoked using Galaxy_S Unlock by Helroz which changes the efs files if i recall correctly.

I want to return it to stock + root (if possible) and i'd like to have the latest stock version from samsung. I believe it's JB. Is there any way to do that? Will i lose the phone unlock capability by doing that?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You can flash the latest stock firmware using Odin. You can get the tar file from the Download Repository (link in signature) at the bottom of the page. It's UCMD8 which is 4.1.2. If you need guidance, just ask.

It is possible you will lose the unlock, although flashing the stock firmware does not touch efs. But I'm really not sure. Sorry I can't give you any better answer on that.
[AT&T Samsung Galaxy S II SGH-I777] zeinoonm:
Hi, thank you for the reply. Is the UCMD8 rooted or non-rooted?
[AT&T Samsung Galaxy S II SGH-I777] cyril279:
The 4.1.2 touchwiz UCMD8 firmware in creepy's repository is the stock non-rooted firmware.

It is very EASY to root the stock firmware, by using the framaroot tool. Then you are exactly where you wanted to be -> stock+root

If you're looking for a rooted, debloated, deodexed, version of touchwiz 4.1.2, then I suggest i777UCMD8 Cooked firmware

happy flashing

Hi guys.. Its been a while scene I posted on xda went with the note 3. My wife has this phone, she's running shostock 3 version 3.0.2 with the i777ucll6 baseband. An the included kernel jeboo v1.36b+ can someone walk me through this process on getting this phone back to stock so she can return it. Her power button went dead. Thanks in advance guys
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Return it to where? This model is nearly 3 years old, and out of warranty.

With a failed power button, you will not be able to perform a wipe data/factory reset from within stock recovery. Therefore, before you flash back to stock, you should perform a wipe data/factory reset from the recovery in the Jebo kernel, which is a touch recovery.

Download the I777UCMD8 stock firmware full package from the Download Repository, and use Odin3 v1.85 to flash it. It's the next to last item near the bottom of the repository.

If you don't have experience using Odin, let me know and I can post up some instructions.

If you are going to pay to get this fixed, you may want to consider sending it to Mobile Tech Videos. They can replace the button for $40.00 including return shipping. They are in the Los Angeles area, and are well respected here on XDA. I believe Samsung charges something like $70.00 or $75.00 for the same repair. And even better, you won't need to flash back to stock.
[AT&T Samsung Galaxy S II SGH-I777] cortez52:
Can you please post instructions been up half the night on this..
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Download Odin3 v1.85 from the Download Repository near the top of the page. Download the stock distribution as mentioned above from near the bottom of the page. The downloaded file is a 7z (seven zip). Use an archiving program to extract the stock distribution from the 7z archive. The resulting file will have an extension "....tar.md5" This is the file you will use in step 7.

If you have further questions, please feel free to ask. Sorry, but I sometimes I don't check the forum more than a couple of times a day.

How to use stand-alone Odin3 to flash firmware:

Follow and recheck each of the following steps. Do them in order listed, as some steps are dependent on previous steps. Instructions are for Odin3 v1.85. It should work with any version of Odin, but some details, like color of items, may be different.

1.) Open Odin on the Windows Desktop.

2.) Have the USB cable plugged into USB port on the computer, but *Not* plugged in to the phone.

3.) Shut the phone off.

4.) While holding down the vol+ & vol- keys, plug micro-usb plug into phone.

5.) In Odin, you should get the yellow box under where it says ID:COM with the text 0:[COMx], and in the Message area, <ID:0/00x> Added!! where x is some number, usually 1-8.

6.) In Odin, make sure Auto Reboot and F. Reset Time are checked and all other items are not checked.

7.) Click on the PDA button. Browse to the tar file you want to install and select it so its path appears in the text edit box next to the button.

8.) Make sure the check box next to the PDA button is checked.

9.) Click the Start button.

10.) You should see the green progress bar advancing.

11.) When complete, you will get a PASS (or FAIL if unsuccessful).
