[help] wifi problem after flashed custom kernel

Hi everyone, i'm running viper 2.4.1 with hboot 1.14 on my phone right now. However, when i tried to flash other custom kernels , i have a weird problem with my phone as it can't re-connect to wifi ( i set my phone to turn off wifi when screen is off). It's always says error and i have to reboot my phone to get it work again. Here what i've did
- flash elementalX 3.2 kernel=> wifi problem=> re-flashed kernel& boot.img=> still have wifi problem
- switch to beatmode 4.4 kernel=> same problem=> reflash kernel + boot.img from elementalX ( beatmode kernel doesn't have boot.img)==> problem still there
- flash stock kernel=> doesn't work, i guess i have to flash stock boot.img but i don't know where to find it
- fresh re-flash viper rom + beatmode kernel/elemenatalX=> wifi problem
- re-flash viper rom only ( with stock kernel comes along with it) => everything works perfectly
===> so i'm stucked right now. i tried to search in kernels thread, viper threads but there is no answers. Can someone help me to solve this problem?
P/s: i always wipe cache/davik cache before and after i flashed things

The kernel is the boot.img
Are you fastbooting the img
WiFi issues almost always are caused by the boot img
Try and fastboot the boot.img from the kernels that you want to use...and make sure their compatible with the Rom you choose

Viper Tom Is compatible with elementalx /beatmode kernels I believe. I also always flash boot.img (comes along with kernel) in fastboot mode.

You r correct sir, flash boot..img is an option with elemental jb 1.3 version plus other goodies from flar, great battery life with viper Rom and that kernel

[Q] Do I have to flash a specific Kernel before flashing CM 10.1??

I'm wondering if I have to flash a specific Kernel before flashing custom roms ( CM specifically ). My device is P3110 running stock 4.1.2 . Any help will be much appreciated, thanks guys.
Edit: Does flashing the CM Rom zip file flash the newest CM kernel or should I flash it manually?

You never want to flash a kernel before flashing a rom because the rom will over write the kernel when it installs its own. If you want a custom kernel flash it right after flashing the rom.
All roms come with their own kernel.
Sent from your phone. You should be careful where you leave that thing.

Thanks

That's exactly what I needed to know, I have another android device ( Xperia mini pro ) and every time I need to install a custom rom, I have to flash its kernel first. Here it seems like flashing the rom via recovery also flashes the kernel. Thanks for the help appreciated.

The CM zip file has everything it needs. You just need to have a recovery ROM to be able to install CM from recovery. Additionally, you might want to reset various things from recovery before installing CM. Notice that if you reset the internal sdcard you will lose all your data (which might or might not be what you want).

Steps to flash ROM from stock

Ok, so got my new XL today, and already want to flash it, can't stay away. lol. Used to all the steps and software and everything from my other phones, but want to go through the steps here first before I flash serajr's ROM. Read his steps, the part I'm not sure on this phone is how to get recovery on.
Ihave flash tools downloading, the current highest stock fw, and his files.
So I have to update to the latest stock first with flashtools and the ftf file.
???? Install recovery.
Flash his 2 files in recovery.
I have no problem in CWM/TRWP/AROMA scripts, etc, just not just how to get a recovery on this phone.
Also, what do I have to do with flashtool to start flashing? Is there a download mode for the XL?
Lastly, no problems flashing the latest stock overtop of the Wind mobile version? It's the C2104, but I'm on the A1 version still and Wind shows no updates available.

I got into flashmode once and now I can't again. Is it vol down and plugging in the usb at the exact time you press down?

New USB cable and a battery pull helped get me into flash mode. Got the A2 stock flashed, waiting on first boot, read it will take a long time for the first boot. Flash looked good though, no errors in flashtool. Like using Heimdall for sammy.s.

Ok, stock boots fine. Can't seem to flash a kernel with cwm. Do i need unlocked bootloaders for that?

Got the latest stock running, can't seem to flash vengence/thunderzap to get CWM.
Do I need to unlock boothloaders to flash the kernels so I have cwm so I can flash segarjr's packages, then flash the stock kernel back if I want wifi working, etc?

You will have to unlock bootloader to flash kernel.
Flash custom kernel containing CWM.
Flash your Rom.
Then again flash stock extended v2 kernel.
Done!
Always flash kernel through flashtool.
Switch off ur phone then connect to usb pressing volume up. It will enter fastboot mode and notification light will glow in blue colour.
Then flash
Done!!!!!

Thanks but I think I'm screwed, I get
"Bootloader unlock not allowed"
So I can't unlock my bootloader to flash a custom kernel. Gonna suck if there is some good dev on this phone. lol.

Oh! Very sad!!
Wait till CWM comes!
Anyway, You can root, deodex your Rom to add some mods
You can also use 'Flash Gordon' to flash anything but Rom..

[Q] Stuck on green htc logo

Hello.
I currently have my pico with stock rom, with sense 3.5. and i'm tryin to flash a new rom, but every time i try to flash one from this thread ( http://forum.xda-developers.com/showthread.php?t=1754876 ) i got stuck on htc logo screen. and i cant get passed it... i've wiped everything, reflashed kernel, reflashed stock, but still cant get it to work. maybe these kernels arent for stock roms, if they're not, can you point some kernels that work on stock?
thanks in advance.

Stock rom should have stock kernel too.

Flash the gingerbread kernels.. they must work. PS: The ROM.zip already contain kernels that get installed when the zip is flashed.

where can i find those gingerbread kernels? so if they're inside the "rom.zip" is it possible to "extract" them to a flashable zip? only the kernel withouth the rom itself...?

Gingerbread kernels are in the Index of all kernels..
From the ROM.zip if you want to extract them then just extract the boot.img normally and also extract the modules from the zip .. in /system/lib..
In fastboot mode flash boot.img via :
Code:
fastboot flash boot boot.img
and
then via adb push the modules. I suggest you search a bit and find some answers yourself . Its easier that way cause these questions have been answered millions and millions of times. So use the search function

i've searched, and believe me when i say that i havnt found anything about this... all the kernels i go for, on the thread only talks about the kernel itself and not the roms compatible... and i've tried that method and got stuck on htc green logo... thanks for answering

these kernels work on stock rom:
1- cranium kernel
2- ateeq kernel
3- garuda's kernel
search them in the development thread I hope you'll find them.

i've tried all those kernels... one by one and never got passed the htc green logo... always get stuck there... i tried flashing trough fastboot and trough recovery... nothing works... any other suggetions?

try to flash ateeq rom then ateeq kernel..it works for me.

but i dont want to have ateeq rom, i want to stay with my stock rom, but change the kernel... only that. but thats for answering. i'm getting used to the idea that i cant be changed (the stock kernel).
thanks

[Q] My problem started day by day

Hello!
Firstly my wi-fi died. (could not connect to the internet, or even get IP adress)[same with bluetooth]
Then I reflashed another ROM, everything went good but day by day again wi-fi is dead.
__________________________
I checked stock rom, and It seems to be ok.
Step by step I :
-flash stock w/ flashtool;
-fastboot kernel w/ flashtool;
-flash phantom/thunderzap with that kernel;
-dirty flash or flash custom rom;
And wi-fi can not even turn on. Why?
So much blue screens occur.
I don't know what to do.
___________________________
P.S. Stock works fine.
edit. Flashed new .ftf and Carbon ROM. Wifi works but LED/flash light/brightness not working.

You need to flash kernel zip again after flashing rom. By kernel zip I mean the zip file that contains boot.img. It contains all the modules that you need for a working wifi.
Also, most roms require a clean flash and not dirty flash. You should check that with the rom though.
Do this:
First flash a custom kernel.
Then flash your rom using the recovery in that kernel.
Then flash the kernel zip(that I told you above). I'm sure your wifi will start working if you follow these steps carefully.
I again suggest a clean install instead a dirty one.
Hope it helps.
Hit thanks if it does.

I edited my post, just problem with my .ftf. I don't know why but I downloaded it one more time and everything is all right now.
Second problem was LED and other lights... It's rom (Carbon) problem, waiting for fix. Staying on Omni rom for now.
