Help ! Kernel version shows 'Unavailable', not able to install even most basic apps

Today i observed a weird thing in 'Settings' > 'About Phone' . The kernel version shows 'Unavailable' !!
This was not the case when i bought the phone. When i bought the phone it was on 2.1 and the kernel version showed [email protected] .... # ... something (Don't remember exactly).
But i updated to 2.2 using kies before few days. Could this kies update be the reason for showing 'kernel version' as 'unavailable' ?? Is my installation corrupt ?? As i bought it used it is possible that he/she may have install lagfix or rooted the phone or anything which may have caused issue during the kies 2.2 update.
Could this corrupt kernel be the reason that i'm not able to install 99% of the .apk even manually ?? The installation always fails with most of the files. I have tried with droid explorer, adb via command line, directly from phone, apk installer app, etc. but I now able to install even simple apps like flash player, angry birds, asphalt 5, asphalt 6, etc.

If your kernel had listed as [email protected] when you bought the phone, then yes, it was a custom kernel, likely one of Chainfire's to root the device.
After the update, I assume you no longer have root?
You could try to flash a new root kernel as described in Chainfire's thread HERE, which would likely solve both the Market problem and the kernel problem.

Are you sure i would be a custom kernel ? I saw a new SGS i9003 on display at a Electronics mall before few days and even it had the Kernel version as root @ ...
And yeah, i don't have root currently.
I want to flash the phone, but the problem is that the 3 button combo is not working on my phone even though i officially updated it to 2.2 via kies. Build is FROYO.NEJP5. Maybe because it is 3 UK branded. I'm thinking of flashing this bootloader update but, just worried because if the bootloader update fails then my phone will brick, i suppose !! If the 3 button combo starts working then flashing kernel and firmware is a bit safe as i can still go back to download/recovery mode! Isn't it ? What do u suggest ?

first and foremost get the three button combo working or order a jig.

Or try 3 UK store .

You may trip Knox counter, our locked boot loader only boots kernels or recoveries it approves of. Nothing stopped us from flashing kernels or custom recoveries, it is just that it wouldn't boot.
In addition you can't root it. Towelroot is a kernel exploit and it doesn't work on MLG kernel. Don't know for sure if you can flash the MLG kernel on an already rooted custom ROM and would still keep root.

If you're having wifi issues not remembering your password once you reboot. Go to this link http://forum.xda-developers.com/showthread.php?t=2793441and scroll through the post till you find wifi issues. Don't update your kernel then you will trip knox and void your warranty. You can also go to this link http://forum.xda-developers.com/showthread.php?t=2838117 and bring your phone back to factory. This second option will clear every bit of data from your phone so make sure you back everything up before using this option.

Are we still unable to flash custom kernels? On Araymod 8.4 rooted. I need to be able to install a good overclocking kernel but am having a heck of a time finding anything.

Custom kernels will not work with a locked bootloader.

Any way to show the carrier text? Mine doesn't show up.

You mean text messages from other people?

No, like in Carrier text on statusbar. It will say AT&T when I'm on the Hspa / LTE network when it hands off it should say AT&T MicroCell.

Rooted stock rom?

I have my G900a and I had to reset it, and whenever I downgrade the kernel to use towelroot my phone wont boot, it freezes at the Samsung logo and then goes black, I was wondering if anyone can give me a rooted stock rom (Doesn't matter what version) download so I can flash it on my phone using odin.
If you can solve my problem with downgrading the kernel without it getting stuck let me know please.
I'm on 4.4.2 but I'm using oa1 kernel, its the only way I could get my phone to boot.
Thanks very much for the help.

If you have 0a1 kernel i believe that you can't downgrade to a different one. I might be wrong but i think i read it somewhere on here. Might try to search it.

If you have OA1 bootloader or lower, which seems to be the case for you, you can download the downgrade to NCE tar file from the first post in this thread http://forum.xda-developers.com/att...w-to-update-to-g900aoca-5-0-keeproot-t3076803 (thanks to @muniz_ri) and flash it with pc odin and take it from there.
EDIT: I tried this and there is some additional steps to make it work. See http://forum.xda-developers.com/showpost.php?p=60135975&postcount=290

Please see my post here: http://forum.xda-developers.com/att...-downgraded-baseband-fixed-4-4-2-lag-t3065973. I had the same problem.

Odin flash auto-reverts after rebooting

Hi guys, i have an s4 active i9295 with a bootloop, so i decided to flash stock rom via odin as i always did with samsung phones with this problem but every time i flash a rom (i tried different ones) the phone restarts as normal but when the samsung logo appears then it says on the top left with blue letters revocery booting, then it does something with a progress bar and an android logo above and restarts. When it boots again its back at the bootloop, im an absolute noob in this but what i understand is happening is that the phone is reverting the flash i did with odin and i want to know what am i doing wrong, is this supposed to happen? Any help will be much appreciated

I'll try to help you, what did you install or modify that caused the bootloop in the first place? Was your device rooted? Did you have custom recovery? What recovery? Did you have a custom ROM? What ROM?

I received the phone as it is with the bootloop, don't know much of its state before but i was told that it was a bad flashing procedure the cause of the problem. It had stock recoverys from the different roms i flashed in odin: I9295XXUDOB4
I9295XXUCNE5
I9295VJUDOF1
There was one time i managed to make it boot flashing CWM and installing cyanogenmod 12.1 but on restart it kept bootlooping again and i was unable to get it to boot again even repeating exactly the same steps i did before.
I want to make an absolute clean firmware flash with the original rom that this phone came in my country (VJUBMK4) but from what i understand once im on newer versions (im not sure if 4.3 or 5.0) i cant downgrade.
I really don't know what is it causing the bootloop, how can i get the pone to factory firmware? Am i doing something wrong?

Ah, it sounds like you have one of the devices with locked bootloaders then if you can't downgrade, if that is the case you can't use CWM, TWRP, CM or AOSP custom ROMs, those devices have to use Safestrap and modified Stock ROMs. Or you may can unlock the bootloader. I'm not sure that is your problem but you can check it out.
You can flash the newest stock firmware and just be done with it, you may not be able to root and flash custom but the device will at least work.

Boot into download mode by holding the volume down + power button and see what is the device name listed there

Take the cover off and pull the battery, the label under the battery should have the model number for the phone.
If the model is GT-i9295, then you have an unlocked bootloader and should be able to flash any firmware.
If the model is SGH-i537, then you have a locked bootloader and can only flash firmware meant for that phone.
Once we know which phone you have we can help you.
