[Q] Why don't our ROMs include kernels? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Could someone explain why Xperias need to have their kernels flashed via fastboot (from a connected PC), while other devices (like HTC Incredible) can flash kernels as part of the recovery process?

Hboot 1.5 - S-ON - Suggested Working Kernels?

I was hoping someone might be able to offer some suggestions here. I have a refurbed Hboot 1.5, unlocked using HTC's tool so it's S-On. I can install ROMs via the recovery and I use the FLASH GUI app to install kernel files. The problem I keep encountering is almost every ROM/KERNEL kills my WIFI. It just reads "error" and I can't resolve it. I have to then flash the one kernel I can keep getting to run, which is: 2.6.35.13-g84f8edd. (SMP PREEMPT Fri Aug 5) from a TITAN ROM.
Yesterday I relocked the phone, install the RUU - updated to 2.17 - but as soon as I installed another rom, it killed the WIMAX again (FRESH) - so I had to use the same 2.6.35.13 kernel.
Is this common, is there a working list of kernels that will work ith S-0n Hboot1.5?
I don't have any trouble with anthrax kernels. I've also used quite a few of ziggy's kernels and not had any trouble.

I have a new 3D with HBoot 1.5. So far; It's been my experience that all AOSP kernels have no WiFi on this phone. This means that if I want CyanogenMod-7 I'll have to do without WiFi.
None of the Sense kernels/ROMs have this problem.
Try using adb rather than gui.
I've been on 1.5 hboot since August and have flashed many roms and kernels. Never had a problem with wifi. Also, the make sure you use kernels that match the rom type... Aosp, sense, update version, ics, etc... Doesn't matter what hboot you are if they don't match stuff won't work.

You have to take the boot.img outta the rom place that in the platform tools folder of ADB.
Then place the rom on your SD card.
1. make sure debug is on
2. adb reboot recovery
3. wipe everything
4.adb reboot bootloader
5. fastboot flash boot boot.img
6.go to recovery and flash the rom
7. Wifi will work no issues rom runs like a champ
If you are using adb and going through fastboot, there is no need to extract the the boot image. Just fastboot into recovery and flash the rom. The kernel built into the rom will be installed too.
with faast boot you can install roms and mods just like 1.4
I have been using flash image GUI and have not had a problem with mikrunny which uses anthrax kernels.

If he is Hboot 1.5 you have to use the fastboot flash boot boot.img other wise you will have a bad kernel flash no wifi crappy 3g among other issues....
Hboot 1.5 users can't just flash a rom with a kernel in it. That is for the folks on older hboots....
Sorry, have done this:
(open command prompt at adb tools folder)
adb reboot bootloader
fastboot boot twrp-shooter-2.0.0RC0.1.img (file is in my adb tools folder)
Wipes
Flash rom
Hundreds of times successfully for many many roms of all types... Kernels, and wifi, and etc... Have all been fine.
I've been on 1.5 hboot s-on the whole time. There are a lot of misconceptions out there about 1.5
Just use flash image GUI. No adb or computer needed.

I don't use TWRP 2.0 due to a few roms it has flashed dirty with issues and some apk files were missing that shouldn't of been along with the roms themes.
Been using CWM recovery.
I know what your saying about recovery. Makes things easy anyways wasn't hammering on you just making things simple
I know the myths about flashing on hboot 1.5
One thing I know you can't do is just wipe and flash a rom using CWM or TWRP 2.0 while in recovery on your phone cause the kernel won't take you have to use adb. Which is what your saying while in recovery. I was thinking you ment you could just flash in recovery without using ADB your method is right. Hope the OP is up to date with flashing lmao might be confused now.. ...

All you have to do is fastboot into recovery and flash the ROM from there. It will pull the kernel from the ROM. if you want a different kernel then put the kernel on the Sd card and flash it after the ROM is flashed.

Yea, but when I do that - I get the WIFI error on almost all kernels used. I then have to use Flash Image GUI to install the one working kernel I have and it resolves the wifi issue for me.
The problem is, no matter if I use Flash Image GUI app, adb shell, bootloader, or install from recovery, it installs the rom fine, but when the system loads, no wifi, tried 6 roms, anthrex kernels etc, all the same.
I really appreciate the recommended steps provided above, I'll try both - removing boot-img and flash boot via fastboot or boot twrp shooter 2 directly and see how it goes. THANKS AGAIN
I've been using the fastboot loading of TWRP 2.0 to flash my ROMs and have had no problems with the Sense ROMs, but the AOSP ROMs/Kernels never would give me WiFi. I'll try the other two techniques of flashing the kernel (GUI and Fastboot flash) and report back the result of AOSP ROMs. It would be great to use an AOSP on this phone, my preferred Launcher SPB 3D doesn't need Sense...

Give fast boot a try no issues for me.
My general method is flash the rom, boot, wifi busted, install titanium, restore flash image gui, flash kernel, reboot, bam...
If I'm in a rush I'll just flash via fastboot.
So far no kernel issues not sticking. Everything works.
Easy answer so this thread can end...
1 match kernel with rom... Asop ROM (cm, miui for instance) need asop kernel.... Sense rom (fresh for instance) needs sense kernel
2 flash rom and kernel with adb (need computeri)
3 flash rom with GUI (no computer needed)
Directions... Flash kernel of choice with GUI then flash rom...
Phone reboots but data broken
Reflssh kernel with GUI now everything works

[Q] No Signal After Flashing A Rom

Someone Please Help Me,
So I Just Unlocked My Bootloader Via HTC Dev
Then I Put TWRP Recovery Onto My 3D
So Now I Try To Flash A Rom Such As Newts One S
Wipe - Install Rom - Flash Boot.IMG - Reboot
Everytime It Boots Up But There's Never Any Signal , Ever...
HBoot - 1.5
Unlocked
Any Idea's ?
Dont know if its the same for you CDMA guys, but it might be a firmware issue. Have you tried fixing permissions in recovery?
Edit: same issue here
http://forum.xda-developers.com/showthread.php?t=1643638
I could be wrong, but I thought s-on users had to flash the kernel and then the Rom. You could also try 4ext as your recovery (see my sig). It allows people who are still s-on to easily flash the kernel while flashing the Rom.

I had a similar issue a few months back....
I was only able to resolve by booting phone into Recovery via CMD prompts on my computer. Something about the 1.5 S-On.

htc evo 3d

i am goin through a really big problem! i was trying to permanently root my phone! but during the revolutionary step it says hboot 1.40.0000 or 1.30.0000 it says 1.40.0000 and it also says it is not supported yet! please help me!
Hi,
you dont need S-OFF for evrything. If you cannot S-OFF,
still you can flash roms, and do most of the things without a problem,
Only thing is you cannot just install custom roms using the recovery menu.
You need to download and installed Android Framework tools and fastboot in your PC to fire ADB Dos commands to your phone via USB to flash the updates.
Let me know.

You can flash ROMs through recovery on S-on too and it will work fine as long as the new ROM contains the same kernel as your current kernel. And if it contains another kernel use flash Image GUI app or fastboot command to flash tha kernel.
Provided your bootoader is unlocked via www.htcdev.com

Most of the time, ROMs does not have the same kernal,
So most of the users who are s-on and new to flashing get stuck on boot loops. Other thing is flash image gui app is a paid application
So best way is to use fastboot commands to flash the kernal after installing the ROM zip file
Cheers..
You could update to hboot 1.50, use the HTCDev unlock and use the Wiretrick to get s-off

[Q] Can roms be installed w/ S-ON?

Can roms still be installed w/ S-ON? I am uncertain as to what the benefits of S-OFF entail and would appreciate an explanation -- thanks!
With s-on (and unlocked) you can:
Flash roms
Flash kernels
Edit /system, while in recovery
Run RUUs (pretty sure they must still be signed)
With s-off you can:
Flash roms
Flash kernels
Flash bootloaders
Flash radios
Edit system from within running Android
Flash signed and unsigned RUUs.

Yeah you can flash roms, the only thing extra you need to do is flash the boot.img through CMD. So you will need the fastboot files from the One X development and put that in C Drive, Then get the Boot.img out of the ROM you want to flash and put in that fastboot folder in c drive. After that open Command prompt and type -
cd c:\fastboot
fastboot flash boot.img

Flashing a kernel when S-ON

I have an HTC flyer rotted by unlocking the bootloader and it is S-ON. Everyone knows that when your flyer is rooted that way you'll need to flash the kernel manually
Code:
fastboot flash boot boot.img
otherwise the kernel will not be flashed.
So now i have the lledroid HC ROM and I flashed the kernel with clockworkmod. (The kernel can be flash within the recovery) So my question is is the kernel now flashed or do I need to do it manualy.
Link to lee's rom (great work on it BTW) http://forum.xda-developers.com/showthread.php?t=1406851
Don't personally know how LeeDroid handles boot.img. If the thread says that it will flash boot.img for you in recovery with S-On, than you should be good. The worst that will happen if try to boot, is that it will get stuck on the boot splash screen. In which case, just restart into bootloader, and flash the boot.img in fastboot.
On the other hand, flashing it manually (even if it was already flashed automatically) typically will not hurt anything either.
I knew that My question was can you flash flash a kernel using a zip file without commands with S-ON

If its not a feature of the installer for the particular custom ROM, then no.
