Doomkernel loop

For the people that are having problems with the doomkernel boot loop.
I solved it by flashing back to stock kernel.
This is sort of already told by doomlord in the first post.
You can find the kernel.su in any rom you want in the FIRMWARES & ROOT Compilation section.
Download the rom you want and extract the kernel.su out of the rom.
Then use the cmd (fastboot flash boot kernel.su).

Problem solved 100% GUARANTEED

After doing this i flashed my rom to .73 combined with the doomkernel V.03
No problems after this

P.S. 1 Question to Doomlord.
Youre great with the kernel and recovery scene.....
Why not make youre own ROM!!!

sessel · Apr 26, 2012

If Doom make a rom , i think is like a dream.When he made x10 dev's kernel i imagine if he make a custom rom for us.
He's like a dream but just the Lord can judged

Delet if my post is disturb

Yes actually u are bang on target....

I spoke to a senior developer and he told me that my current script to flash kernels could create issues as the kernel/boot partition needs to be erased before flashing!!!! I am working on a better version of the flasher script that should correct the issue... Till then I request you to use fastboot to flash the kernel.elf as it will first erase boot partition and then flash New kernel...

Please test this way on #9003

P.S.: i am not interested in ROM development

hmm might be true
I just flashed 9003 via fastboot, it's not bootlooping anymore !

gm007 · Apr 26, 2012

not for me

i just tried 9003 with fastboot but still have the freeze while booting.
maybe my phone does not accept the high freq 1890 MHz.

I'm using v03a #9005 test kernel and have one problem :
When I mount Usb storage to Usb OTG cab, mounted popup appear but I can't acces to the usb.

P/s : Before stock kernel is no problem

Thanks for Doom's kernel first.

Here is my quick report:

#9001 good
#9002 good
#9003 it reboot all the time, but i can use it for few minutes then it boot by itself, even i force it to lower clock by incrediCoitrol, still bootloop.
#9004 good
#9005 good
#9006 good Antutu got 72xx score. higher then other? update 2-May-2012 : freeze once, reboot once.
#9007 good

conclusion is: 9003 has some item need to be tune, may be not just the highest freq setting? i guess

Did I miss that one? Want to test.

One question, the gsm signal is parameter in the kernel or in the firmware?

No idea what you mean by that. You can't really increase response in kernel space

Because it's seem's i've a better signal with Doomkernel but i wan't to have a the confirmation of this.I leave in a house where the signal is strangtly slow and i've a lot of scan to have signal.Now i've more scan to find a signal but it's better when i've.
If it's in the kernel can it be better or if it's in firmware i want to test different version.

im sure u will correct me if I am wrong but doesnt the kernel just display the data from the baseband and soc to the OS to display the signal so any tweaks at kernel level would not actually give better signal but may show a higher level.. if any major bugs exist then the baseband needs the change? but then again if the signal does lock on more often then the kernel could effect that..

Looking at the code I don't see anything baseband related in the kernel.

If I try to enable zram I got an error message.

Device or resource are busy

I'm using kernel v3a

signal strength is not kernel related... and i havent touched any code relevant to that in kernel...

it means zram is already enabled...

are u using any scripts/apps to enable it at startup?

u can check if zram/swap is already active by the following command:

I've just installed #9003 via fast boot and it did boot into the OS and get past "Preparing Internal Storage" but lasted less than a minute before rebooting itself.

Doom is there no stock kernel with root and recovery for the S. Like you done with arc. Not keen losing nice Sony logo on startup. No offence to doom screen.
