Question regarding kernel

Ok... this is weirdest bug i ever seen.
After wipe all data (all thing) up new rom eg. paranoid, AOKP, myOneV... all of them.
1/Stock kernel is default, but modder need uploaded new kernel to run ether rom.
2/Flash new rom needed...yeah we got new kernel at first time... but when reboot phone.... what the f.... auto back-up to default kernel??
IE: AOKP, myOneV, CM10, ... need newest kernel to run, done... but only first time, the second boot is bricked....
=>Solve this for me plzzzz
My idea: why we don't cook new kernel vs new rom when release new version?

lemme explain what did he say, he got prob when up new rom, the rom needed flash boot (new kernel), he know about it. The 1st is flash, boot to phone, he can see new kernel in setting then use whatever like overclock, undervolt, install app,... then he make a reboot (restart) go to setting menu, he regconize the original kernel is back, overclock is disable, same at undervolt and bricked phone if original kernel no compatible with that rom. That's the PROBLEM.

1/Go to fast boot
Open cmd
Fastboot flashboot boot.img <---- which boot.img? "stock kernel"
When flashboot device MUST restart, i cant resist that...
2/Now don't restart go to the recovery and wrote all cache
Wipe all data or wipe all cache? dalvik cache? can u explain....

See when u go.to a rom page there will be a link for kernel......and take the kernel and don't restart our it will be stuck in boot loop....
No go to recovery with out restarting....wipe all data if a new rom...
And then download the link and

i think they are using hassoon tool to flash the kernel, because that script will automatically reboot the phone after the kernel is flashed .
1.You need to first, take THE kernel for the RESPECTIVE ROM
2. Rename it to boot.img
3. You have to have installed the Android SDK + the platform tools to be able to take advantage of fastboot
4. Reboot your phone into bootloader.
5. Connect your phone to your PC.
6. Press start, enter RUN and type cmd. Press enter.
7. Type your path where your sdk is installed (i.e CD C:\Program Files\Android\android-sdk\platform-tools\)
8. Put the boot.img into the platform-tools folder
9. Now go back to CMD use "fastboot flash boot boot.img" without the quotes.
10. It will send a message like "sending boot.img.... done... writing boot img.... done.... elapsed x seconds).
11. Reboot Recovery from bootloader.
12. Wipe everything and then flash your rom.
13. Reboot and that's it.
As simple as that. If you don't know how to use android sdk or you don't have it installed, simple use the search bar and type android sdk tutorial.

[Q] LT26 stuck at Sony logo after failed flashing

Hello, at start I apologize for my poor english, but I hope, that you'll understand what's the matter.
First I prepared to install new rom on my Xperia - I've rooted phone and installed CWM. After that I've launched CWM, then I've erased whole phone's memory - cache, system, data and dalvik. When I want to install rom from .zip file i get info, that file is bad. Next I've tried to launch mass storage mode to copy rom one more time and CWM was unable to open ums lunfile. When I've rebooted phone only thing I saw was Sony logo. Now I'm stucked at it. Phone have locked bootloader, so I can't launch fastboot mode. Adb can't find any connected devices. What can I do now?

Help Please.

Use flashtool and flash a stock ftf.
You must have unlocked your bootloader and hence seus gives that error.

yes, I unlocked it, I made a flash with a stock 2.3.7 rom, but I want the ics but I can not find a cwm for this rom.

Okay, so here is what you must do :-
1. Download stock ics ftf from here - http://ni.0a0.in/files/3432_kznsa/LT26i_6.1.A.2.55_SG Generic (1257-6921).zip
2. Extract the zip to get the ftf file.
3. Flash it with flashtool
4. Flash this custom kernel - http://forum.xda-developers.com/showthread.php?t=1729280
5. Then go and check out any custom roms that you like
All (most) custom kernels have CWM in them. As you have unlocked your bootloader, you can flash a custom kernel and get CWM. Also, each time you wipe /system nothing will happen to CWM. CWM remains intact
Good luck!

[Q] Will installing new ROM wipe X-Parts CWM?

Hi, question: I failed time and again to get CWM working, but finally got it to work using x-parts. However, x-parts is keen to point out that it is not a fully fledged recovery and that "if you wipe the system partition for any reason, it will be gone!".
Does this not mean that if I boot into recovery and install a new ROM (Going for the FXP CM10 one, if it matters), then when I wipe the phone beforehand I'll also wipe my CWM install, thus completely bricking the device? Would appreciate any thoughts, thanks

Yes, if you wipe the system partition there will be no more CWM. For CM10, you need to flash a custom kernel for it to work. This custom kernel will usually come with a CWM recovery so it will not be wiped when you flash a new ROM.

Thanks. But, to clarify, once I flash new CM10/Jellybean Kernel, my current Gingerbread install will also completely cease to function right? And I'd need to flash back to something earlier to get it to work, if I so desired?

Is your bootloader unlocked?
And yes you will have to flash GB ftf using flashtool
Sent from my LT18i

Yeah, I unlocked the bootloader and rooted it ages ago, but have since neglected actually updating the ROM, decided I can't live in a GB world anymore though.
So, as I understand it, process would be flash a new GB kernel to get CWM > Wipe Everything > Install the relevant ROM and GApps > Done? Does this ROM installation include the update to JB kernel then? Thanks

If I am not mistaken the kernel boot img should be inside the ROM zip. Check the ROM zip. Just flash the boot img using fastboot, boot into CWM recovery and flash ROM & gapps.
僕のLT18iから送られてきた

Ah, ok, well this brings me full circle. Because I'm trying to follow the boot instructions to do so, but:
fastboot -i 0xfce flash boot boot.img
doesn't work. I've taken the boot.img out of the ROM, and put it in the platform-tools folder. But whenever I try this line, it says it can't boot it, and quotes "no error" (no longer at home so can't quote the exact error, but it's something like that). I assumed the problem was me lacking CWM, hence was trying to install that first. Fastboot devices DOES show the device, and both fastboot and adb commands work in a terminal, but I just can't get it to boot into the ROM recovery for Cyanogenmod. Driving my crazy! Thanks

fastboot flash boot boot.img, if I'm not mistaken, is the right command. I use flashtool

[Q] Xperia S: from unlock bootloader to recovery to flashing ROM on MAC

Hi.
I'm trying to unlock my bootloader on Xperia S in order to flash CM11 ROM.
I followed this website: unlockbootloader.sonymobile.com/instructions and I'm stuck at #9.
Download and unzip this file. This is the standard android_winusb.inf-file, with a few lines of code added to enable Fastboot to support Sony and Sony Ericsson devices. Make sure you are running Google USB Driver package revision 4 or higher in your Android SDK. You can see current Google USB Driver package revision in the SDK Manager.

As I'm using MAC, I don't have Google USB Driver and website doesn't mention anything for MAC users.
I can't fastboot my phone. :crying:
Please help.

hmmm bro, i think you have a same problem with stuck in boot logo after unlock the bootloader right? just try to flash the stock rom with flashtool and check list the wipe data and cache in flashtool and after that flash it and wait. after boot up you can install any kernel for recovery mode and any custom rom for your development.

my brain is also freezed now.

This may be the solution.
Hey brother,
Even i encountered that problem before, even i followed the same steps mentioned in the official sony site and was successful in wiping out my stock ROM and got stuck into the boot logo "SONY".
Then i tried to reset my phone using hard reset keys but didnt work.
i sincerely suggest you not to use flashtool.exe( which will open up CMD and u type series of codes ) .
Then i used Androxyde XPERIA Flashtool ( now new version is released) you can download from
here : http://www.xperiafirmware.com/compo...2-uncategorised/30-androxyde-xperia-flashtool
Download the .FTF file of your phone and connect your phone in Flashboot mode ( it may be volume down key , search for ur phone).
Then make sure you check Wipe data and cache partition and click the flash button.
I use Sony Xperia M Dual C2004. it worked for me and i am sure this will work for u too. if u have tested with this method and if it didnt work then i am so sorry i cant help u but trust me this will definitely work.:good::angel:

Hey brother,
Even i encountered that problem before, even i followed the same steps mentioned in the official sony site and was successful in wiping out my stock ROM and got stuck into the boot logo "SONY".

so the step is re flash the firmware with ftf.file after that you do wipe data/factory reset? only that? i think that what i do, but i don't do any wipe data? pok it's not necessary, but first your phone has succesfully boot up right with unlocked bootloader Good job and happy flashing anyway:silly:

Hey there,
When you flash .FTF file all your data on your phone will be erased , even the /System. So it restarts as good as before. Dont know whether this is the exact explanation but i did see this on Flashtool. so that made me tell this .. if u came through the exact explanation , plz do comment here. they are many waiting to learn. thanks:good::angel:

but i think is that we can choose right? is that we want to wipe it? data or system in flashtool before we flash the .ftf file right? so why you say when we flash it the /data also erased automatically? i've flash it when my phone still locked bootloader to update 4.3 from 4.1.2 and my data is save? why?

Yes

Hey there,
Yes we can select whether to wipe out data or not but the reason i mentioned is i want his phone to turn as new as before , you can exclude
wiping out the data but the remains of files in the /System can lead to undesirable , i never experimented but read in few blogs and few tld me abt this and that made me write it .so i never wanted to take chances and thats y i suggested him like that
i am no expert and still learning . but it is recommended to wipe out data and cache . thats what we do when we flash a custom rom right?
hope i was clear. thnx , gud day:angel::angel::good:
