[Q] Stuck on Boot Screen after attempted Kernel Install

[nbarr7655]

Hello all. I have had Shostock3 for a while now and read that if you use the Siyah Kernel with it then it is an awesome combo. Well I downloaded the kernel and went to install it through CWM and now I have a big problem. I chose to reboot and install the kernel and when I did I am now STUCK at the screen that says "Samsung Galaxy S II GT-i9100" with the yellow triangle. I have let it just sit and see what it does but it goes no where. WHAT DO I DO?!?!?! HELP! Thanks all!

Samsung Galaxy S II i777
Running Shostock3
WAS running with default kernel that comes with Shostock3

EDIT: It doesn't seem that I can get into the recovery mode either. I am trying the volume button + power button combination and having no luck....

Which siyah did you flash. The one you want is called AJK now

/Siyah-I777-v7.9b-S.zip

Is the name of the file that I tried to put on. Should I try to get the one that you stated and put it on via download mode? Because it seems that I can get into download mode but that's about it. I can't get into recovery.

Hold power button plus volume up and volume down, keep it held in until you boot into recovery. Recovery won't just disappear, normally people just aren't holding them in long enough or are using the wrong button combo. Let us know if you get back up and running. Also make sure when installing the siyah kernel you're following the OP directions to the letter.

I can't get into recovery. I simply cant. I hold the buttons, correctly might I add, and then the logo appears, then goes away and I am left with nothing but a blank, black screen. The bottom buttons aren't even lit.

 

[Phalanx7621]

Possible hardware failure on your power button or one of your volume buttons I supposed. Have you tried flashing a siyah.tar file in odin to get a.different usable recovery?

If you could link me a Siyah kernel that is in a .tar format I would be appreciative.

 

[gireeshtty9]

Dude do as Phalanx says. Vol up+Vol down+ Power and even after the logo goes away dont release the buttons. Recovery will show up.

Either that or if you get adb up an running on your computer, hook up your phone via usb and type (this is for mac, may be slightly different for other os's):
adb root
adb reboot recovery

and voila! your phone boots up in recovery!

can't get past boot screen on siyah 5.0.1

I spent all the time I could thinking I had this but apparently I don't!
Have AT&T Samsung i777 running the latest stock 4.1.2 that I got from Kies.
Wanted to try my hand at custom roms.
Was able to root phone using flamaroot which gave me SU ability
Bought Mobile Odin pro, downloaded Siyah .tar file and put it on SD.
Flashed it with mobile Odin.
Because I'm an idiot, I was hoping to make a rom backup after flashing.
Now, it boots "Samsung" then the Siyah screen, then goes blank.
I can get into CWM recovery but without a backup rom to restore to I'm not sure what to do.
Also, can get into Download mode which reads:
ODIN MODE
Product Name: SGH-I777
Custom Binary Download: NO
Current Binary: Samsung Official
However, it reads downloading, but I do not believe there's anything to download and it's been like this for 20 minutes
ANY ideas on what I could or should do would be GREATLY appreciated. Thanks!

Where did you get the Siyah 5.0.1 in tar format? It sounds like you tried to flash a kernel that is not compiled for your phone. You need a kernel that is compiled specifically for the SGH-I777.

If that is the case, then you should be able to recover by flashing a good kernel using Odin, if you can find a tar version, or just flash the 4.1.2 stock firmware with Odin, which you can get from the Download Repository or from sammobile.com/firmware or Samsung-updates.com.

But first, since you can get into recovery, try performing a wipe data/factory reset to see what happens.

Thank you so much for helping me! First of all, I used your post, "Odin3 One-click Downloaders for Stock and Stock + Root" and was able to follow those steps to get me back to 2.3 and then I connected back to Kies to get back to stock 4.1.2. SO, I am completely back where I started a week ago, but I have a phone that works thanks to you!!

To answer your question: because I was using Mobile Odin, it only recognized .tar files and I found one on Siyah's blog (gokhanmoral) which was categorized under "sgs2 kernel".

So I'm back to the start (actually did the unrooted one so I don't even have it rooted currently). However, with all the reading I've been doing on this forum, I can't shake the desire to use a custom rom. I know I'm very much a noob and probably should make myself happy with my phone, but I wanna give it another try. I understand with my following questions if I'm posting in the wrong area and cannot have my questions answered.

Here's where I'm stuck. I know I need to make a custom recovery (cwm or twrp I'm not totally sure) before flashing a custom kernel and then rom. But I just can't figure out how to do it. When I go into recovery (holding volume buttons and power), there is not option for "backup and restore". How can I get a backup of my current rom so I can start with the other stuff?

The order as I understand it:
1. root phone
2. install cwm or twrp in order to create a backup of current rom
3. flash a custom kernel
4. flash a custom rom (that is compatible with kernel)

Thanks so much again for all your help!!

OK, glad your're back to working. The Siyah kernel you flashed is for the GT-I9100, the international version of the Galaxy s2. As I said, you will need a kernel that is compiled specifically for the SGH-I777, so get your kernel from the I777 Android Development Forum.

Next, you can also use a straight zImage file with Mobile Odin. You don't have to have a tar. You can even download a ClockworkMod flashable zip file and use an archiving tool such a Win Zip or 7Zip to open it and extract the zImage from it. Then use that to flash through Mobile Odin.

You currently have the stock 3e Recovery, which does not have a backup facility, nor the ability to flash custom firmware (unless it is signed by Samsung.) So you need to install a custom kernel with ClockworkMod Recovery (or TWRP Recovery will also work.) By the way, those are just different developers versions of almost exactly the same recovery functions, so it doesn't really matter which you use.

For a kernel, go to this post in the development section and download the third of four which is titled "AJK v2.0.5 NO-SWAP Samsung." As I said above, extract the zImage from the zip and use that to flash in Mobile Odin.

Also on this phone, recovery and the kernel are not separate, they are one unit, so you install the kernel to get the custom recovery. Your steps 2 and 3 are incorrect. Remove step 2 entirely. Step 3 will install both the kernel and the custom recovery. In step 4, you can flash any custom firmware you want. They all come with an included kernel, so it doesn't matter what kernel you start with because after you flash you will have a different kernel anyway.

And finally, don't worry about backing up the stock firmware. If you mess up the flash, or soft brick the phone, you can just reinstall stock as you did before. After you have a custom firmware installed, and have your phone configured exactly the way you want it, then is the time to make a backup, because you can flash to a different custom firmware to try it out, and if you don't like it, you can restore your backup and be back to exactly where you were.

Wow, excellent information and I cannot thank you enough for taking the time to help me out. My last question hopefully, and I don't mean to try your patience but what is the best way, would you recommend, to root my phone? I did it with flamaroot previously but it was temporary? Thanks!

I have no experience with 4.1.2 and framaroot since I'm running Shostock3. No one who has used that method has said anything about it not being a permanent root. Why do you think it's not permanent?

I think it will be fine. Anyway after you root you're going to install a custom kernel followed immediately by a custom firmware which will be rooted. So even if it wasn't permanent it wouldn't matter.

First off, this forum is not for your phone, it is for the SGH-I777 AT&T Galaxy SII, so we don't know the specifics of your phone.

Following the above procedure will put your phone into download mode, where you can flash the firmware you linked.

Since you say you don't know how to use it, I am going to post a complete set of instructions for using Odin that I wrote some time ago. Bear in mind that this is for the I777, and you will have to adjust some things to make it work for your phone. Refer to the flashing instructions in the thread you linked.

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.) 3.) 4.) Put your phone into download mode.
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).

If after the successful flash your phone does not boot into the firmware, then perform a hard reset. I don't know your phone, but normally you would boot into recovery and perform a wipe data/factory reset.
