    Rooted and all is going well, except that all msg notifications turn nav buttons on reducing batt life if not noticed. Anybody else have this issue?

    I have had my phone booted ever since I got it, but am still kind of an newbee. Anyway, I followed the steps exactly in post 1. At the step that says when the ATT screen comes up remove the usb cable. I did. I have the boot screen as described however the phone seems stuck on that screen. It has been over 30 minutes and the boot process has not gone any further. Help please

    Have had my phone rooted some sometime. Went through the steps in post 1 exactly. When I pulled the USB out at the ATT screen the corn screen as described came up but nothing more has happened in over an hour. Any ideas Please.

    First, confirm you are flashing the correct file with Odin. If so, pull the battery and try and boot it with the USB cable unplugged. If it still gets stuck repeat the process of putting the phone into download mode and flashing with Odin. This time when the phone reboots, leave the cable plugged in. When booting up the first time after flashing it, it may pause on the splash screen for a few minutes, but if the screen appears to be stuck for longer than 10 minutes, we might want to try and boot into recovery.

    I re-downloaded the Korn Kernal file from the link in post 1 Re flashed using Odin (from post 1) and my 10 minutes is up and the phone is still on the corn screen. with the Systems Corp name at the top and the blue thermometer (full) below

    I could get nothing to work. Finally used Odin to reflash with KK4_stock_kernel.tar and I897UCKF1-AutoRoot-DesignGears.tar. I used these originally to root. This time using the process exactly as listed in the post Odin indicates all is well but none of the programs that require root can get access to super user.

    Is there a solution? Thanks


    P.S. This is the link to the procedure I used

    Here is what I think your problem is, I897UCKF1 is version 2.3.3 but the korn kernel you are flashing is for 2.3.5. You should flash your phone back to stock, then update it with Kies to 2.3.5 and then flash the korn kernel.

    Before I started to flash to the korn, I checked the phone and it listed the system as 2.3.5. That is why I started the process to flash to korn. Am I confused, most likely yes. Current settings are Firmware Ver. 2.3.5
    Baseband Ver. I897uckk4
    Kernel version
    Build Number Gingerbread,UCKK4

    How do I flash it back to stock? Is that where I go into settings, Privacy, Factory Data Reset, and erase all data on phone? Or do I go into boot into recovery mode and do a wipe/factory reset

    Thanks for your time and help

    lunatic59 Moderati ergo sum

    UCKK4 is 2.3.5 and should work with the korn kernel, but I have seen it lock up on occasion, especially if the phone is not reset or the cache not cleared prior to flashing. You could try a factory reset and clearing the caches, but if that doesn't work, while it's tedious, in order to be working with a clean stock install, I'd flash the phone completely back to stock.

    [STOCK ROM] Odin3 One-Click Downloader and Drivers CAPTIVATE ONLY - xda-developers

    This will put your Captivate back to out-of-the-box condition with Android 2.1 You will then want to use Kies mini to update to 2.2 and then again to 2.3.5.

    At this point you will root with the korn kernel and you should be able to flash an ICS rom with CWM.

    Will Il be rooted after I flash to ICS using CWM/
  12. lunatic59

    lunatic59 Moderati ergo sum

    If you use the korn kernel, yes, you will remain rooted.

    Thank you!!!! Rooted and ready

    If I install ICS, I assume from your message that I will have to set my phone up all over, Correct
  14. lunatic59

    lunatic59 Moderati ergo sum

    Yes you will, but as long as you have backed up your data, it's not a big deal. Do you know which rom you are going to try?
  15. dbwill

    dbwill Newbie

    I am thinking of using,


    I may not do it for a wile as my Titanium Backup did not do as good a job as I would have liked. Do you have a suggestion for another app that might do better?

  16. lunatic59

    lunatic59 Moderati ergo sum

    I'd go for Doc's master ICS Rom (your #2 choice). I've put it on several captivates and never had a complaint.
  17. dbwill

    dbwill Newbie

    Sorry I wasn't clear. When I used titanium recovery, i wasn't pleased with the results, had to do quite a bit of setup. Can you recommend another backup that might do "better".
  18. lunatic59

    lunatic59 Moderati ergo sum

    A nandroid (recommended) backup will create a complete image of your current setup and you should be able to restore that any time a flash goes awry. Titanium is generally the backup that I use but the Pro (paid) version can backup all or groups where the free version I believe only permits backups individually. As for other apps, sorry, i don't have enough experience with others to recommend an alternative.

    Have had my Cappy since Oct of 2010, and my only updates have been through official channels. I had weird issues with touch screen not responding after update to GB, and thought I'd pull my hair out. Tried going back to 2.2 @ ATT Repair site- but they screwed that up too.

    Anyway- I finally did this process last night, and then this AM wiped battery stats, and grabbed Titanium and uninstalled 4 ATT apps.

    I have noticed that since I've added the Corn Kernel and rooted- my reception indicator is very weak. It often changes from 3G to Edge, shows no bars, and with Wifi- very weak as well. Any suggestions?

    I do not seem to have any of the reboot issues listed. I have noticed more breakup in my conversations today.

    Thanks Geeve and company for all of this!!!

    Do not use rom manager with Samsung phones. It has trashed your custom recovery and you will have to re-flash the kernel to get it back.

    Sorry, let me see if i undestand, you mean I have to revert to stok with Odin one click install because the Kerney i install is not compatible with my samsung SGH-I897 ?
  24. lunatic59

    lunatic59 Moderati ergo sum

    No. You should re-install the kernel package you used to root, which will reintstall ClockworkMod Recovery. Rom Manager breaks CWM and you will not be able to boot into recovery to flash custom firmware. For example, if you flashed the Siyah kernel with Odin to root your SGS2, then you should install it again the same way you did it the first time.

    I have two Captivates, mine and my wife's. These are identical, bought the same day, running Gingerbread, updated using the same Kies installation. Cornkernel 7.05 works fine on mine but crashes regularly on my wife's - during phone calls, using apps, just sitting there doing nothing.
