Hi!
I just flashed CM9 and a custom kernel on my Xperia Mini Pro (after some noob trouble), but I'm still having some problems.
I already did some searching but really can't find anything that works.
1. I can't turn on wifi, don't know if that's because of cm9 of the kernel
2. My hardware keyboard is now querty, and for some reason the option to change the mapping of the keys in cm9 doesn't work..
3. I can't change anything in the processor configuration
Help would much be appreciated!
Greetings,
Gi11i4m
You have flashed which kernel??

You have to flash the cm9 kernel. The boot.img that's included in the zip for cm9. You can't use the Karmarush kernel.
I think I already tried that.. Worked with cm7 but not with 9. How should I flash the kernel now? Can I just flash it or should I return to stock rom first? Or backup my data, do a factory reset and flash the both again?
Also, in the update guide on the cm wiki, it says to use this command:
fastboot -i 0xfce flash boot boot.img
But I read a lot about people just using the command without "-i 0xfce"
so fastboot flash boot boot.img
what's the difference?
It's the same command. Just open the CM9 zip and extract boot.img, then flash it using fastboot.
CM9 kernel has some problem, it is not succesfully booting up.
"FXP 127" kernel is recommended to use.....
Yeah, it appers that way. I tried a few kernels but the original cm9 kernel doesn't boot (black screen only).
When flashing fxp127, do I have to change the cm9 ROM as well? Or does this have nothing to do with it?
And, is there a site where you can download ONLY the kernels? Cause I found the free xperia project host from Google, but I can only find the changelog of the kernels, not the download mirrors.. I'm currently downloading the whole fxp128 with cm9 since I can't find fxp kernels separately
Okay, I flashed the FXP128 CM9 ROM and Kernel (think FXP127 is for x10?), and this works flawlessly! Should've done that from the start

Hi Everybody. As the title say, I am facing issues with the touch screen when i install Any CM ROM(FXP-Official)/AOSP. At the first boot I Can not unlock my phone or skip the "Tutorial". After Reboot the phone, the problem is still there
*I Flashed the BB recommend for each ROM (.72)
*I Installed the Respective Kernel via Fastboot:
- fastboot flash boot boot.img
Then
- fastboot boot boot.img
*I did a Full Wipe (Cache, Data, Dalvik)
*Format - System
*I flashed ROM
* And....Nothing
Any Solution? Anyone?
Thanks
EDIT. Every SE based ROMs (MIUI etc.) work without that BUG
EDIT. 03/03/13 AROMA Installer also does not work (Only with Vol and Menu buttons)

I know, I did that when i was installing FXP113 or 115 (With respective kernels) i mean the problem is with FXP Kernel and ROM .... Is there any patch or something?
UPDATE: Please Someone Help me... I tried the ICS Official Leak from here ,http://forum.xda-developers.com/showthread.php?t=1594651 and following the Instructions, i STILL get the same issue...: The Touch Screen Does not Work (Hardware buttons works) Anyone?
PS. With AOSP,Mooded and other ICS ROMs with Nightelf,Pwn etc Kernels i don't have that issue
I have the same problem with Cm7, CM9 and MIUI and its kernel in the zip file, but I can not find solutions. My touch screen works only with stock rom or with official Ics kernel beta and Ics rom official and hybrid rom. Solutions?

Sure you did flash custom kernel with "fastboot flash boot boot.img"?

HiTaaviu,I flashed the costum kernels included in the zip file CM9, CM7, and I also tried Pwn and NightElf kernel, but the touch screen does not work with MIUI cm7 and CM9, touchscreen only works with the stock rom and MooDeD ICS ROM, JJ's HYBRID ROM, AOSP 4.0.3 ICS, ICS SE Beta official with the official kernel ics of sony.
then the problem is not flash the kernel, because ics official kernel works perfectly and then flash the kernel run correctly. But why with the other kernel touch screen wrong?
I do not know how to do it, I can not find any solution!

Pleas write here steps "how do you install MIUI or cm7-9 rom"
Thanx
Etc..
1.downloaded rom xxx.zip
2. kernel xxx.img
3. wipe?
How installed kernel/rom.
Ok, this is the procedure I follow:
1 -Flash .42 with Flashtool
2-Root
3-Unlock bootloader with fastboot (fastboot.exe-i 0x0fce oem unlock 0xMykey)
4-Install cwm recovery
5-Iput zip file downloaded to sd (ex. update-cm-7.1.0-XperiaNeo-MT15i-signed)
4-I put the kernel included in the zip into the fastboot folder and flash (fastboot flash boot boot.img)
6-I go into recovery and wipe data / factory reset, wipe cache and wipe Dalvik cache
7-Flash zip rom and GAPPS
8-Reboot
9-Phonework but touch screen does not work
I tried with pwn kernel and other but it is the same thing!
The situation that presents itself is equal to this video:
Boot ZTE Blade / Oranage San Francisco (B10) with custom rom with working touch screen(Search in youtube)
I also tried to use the technique in the video but without battery Xperia neo will not turn on.
I do not understand where I'm wrong!
First of all flash .62 ftf by flashtool...then flash the respective custom kernel for the rom...wipe everything and also format everything in cwm ...all custom kernels are pre rooted and cwm recovery ready...now flash the rom and see if it works.

The problem is still here... I tried Every ROM based on CM9 (since FXP129 to CM9 RC2 Official) or AOSP (Polish Blood 4.04) and don't work... Others ROM based on SE (MIUI etc.) Work flawless... WE NEED SOME DEVS HERE, Please...
please, no one can solve this problem ???
Lemme try.
Flash the latest Stock firmware. Boot it up, and go thru the whole setup process. Stock FTF usually got no probs when it comes to hardware.
Run the phone in Stock for awhile (1-2mins), then shut it off. Go into fastboot mode (press and hold "Menu" button while plugging into PC) and flash the kernel from the LATEST version of the ROM you want to use (FXP146 for CM9.1/CM10, FXP110 or something for CM7.2, MIUI2/MIUI4/MIUI4.1). It is usually in the zip itself or the dev would have recommended a kernel. If you don't know how to flash the kernel, PM me.
Boot up phone into recovery, flash new ROM, flash gapps, reboot phone.
BOOM all should be ok
Hey guys,I own optimus one and I m used to rooting and stuff but my brother owns xperia mini pro so I need to install cyanogenmod (9 or10) whichever is stable.I had gone through various guides and stickies yet I want to be dead sure that I don't mess up my brothers handset. Its kinda new coz bootloader needs to be unlocked and also kernel image needed to be flashed separately unlike in optimus one.
Now I want help of you guys in the following manner like:-
1. My brothers mini pro is on ICS 4.1.B.0.587 and the rooting tutorial provided here for the said firmware
http://talk.sonymobile.com/thread/41119?start=0&tstart=0 is not clear to me coz it says that first I need to install some kernel [only mini mentioned here] then next I need to flash another kernel according to firmware. Can someone explain what is being done in this and why rooting is so complicated in this.
2. Certain ROM's say that you need to flash kernel first using flashtool
My query is that all ROM's that I flashed till now on optimus one included kernel and I only needed to flash ROM zip through cwm.. So do I need to flash kernel everytime I flash ROM!! and isn't there flashable zip for kernel too!!
3. FXP ROM's do not contain things like what's working and what's not, it only has issue tracker so it become difficult for new comer to know the bugs in ROM. Can anyone tell me the least bugs cm9 & cm10 ROM and what are the bugs present.
4. Lastly, should I proceed like this!!
i. Root device (though method isn't clear to me)
ii. unlock bootloader
iii. install cwm (I guess I can do this using flashtool)
iv. backup current ROM along with kernel (for future use,I know its optional)
v. flash kernel using flashtool
vi. flash ROM through cwm.
I m a quick learner and I just need some guidance on this new device (double checking coz its my bro's device) . Looking forward for support. Thanks

You needn't root first if you want to unlock bl, just unlock bl and flash a custom kernel (in most custom kernels cwm is included).
Backup your rom and install the rom...
hmmm....
1. Unlock Bootloader........
2. Flash Custom Kernel (all custom kernel is per-rooted and have CWM).......
3. Boot into CWM and Flash CM9 or CM10 (factory format/wipe dalvik/cache).....
4. Boot into Fastboot And Flash FXP kernel for CM9 or CM10.....
xperia phones aren't like sammy, lg or htc where recovery is a separate partition from kernel. in fact, by default xperia phones doesn't even have "stock recovery" like on other phone. by that we integrate cwm in kernel ramdisk.
and to answer the question:
1- flash custom kernel mean't for your phone only, never ever flash kernel intended for other phone. and its done via fastboot and should be flashed before flashing rom.
2- like i said u can't compare xperia phone with other phone like sammy etc, its different. kernel must be flash via fastboot.
3- for cm10, bugs that i notice is slow accelerator, but fixable with some text editing, and non working front camera for lww and minipro.
4- should be like this, according to order:
- unlock bootloader.
- flash kernel via fastboot.
- boot into cwm.
- backup rom if u want.
- wipe data, cache and dalvik cache. don't wipe system partition or u will get error when flashing rom later.
- flash rom, and gapps if its cm/aokp/pa rom.
- profit :good:
thank you guys.... this made me clear...
one last thing :- which kernel should I flash on stock 4.1.B.0.587 which is pre rooted and have cwm after unlocking bootloader.I mean the one compatible with above firmware and also do I need to do anything with baseband or will it be compatible. After this m ready to enter the custom xperia world
Remember to backup your stock rom before unlocking the bootloader as everything will be wiped clear.

No, i just meant that backup up your contacts, messages, apps (can be done through astro file manager) etc, before unlocking your bootloader because unlocking will wipe your data.

Hello
I am a newbie Android user though I flashed Real ICS r6 and Extended Stock kernel a few months back. The ROM is great, the kernel works fine. But I wanted to Overclock and use Swap File which isn't enabled in extended stock so, I wanted to install MESA which is compatible with Real ICS as well as my phone. But I have no idea how to flash a NEW kernel.
If I flash a new kernel does my ROM get erased too?
I need a detailed step by step tutorial about flashing MESA and replacing Extended Stock with it, without removing Real ICS r6. Any help is appreciated guys. Also, please take note that I cannot brick the phone as I won't get a new one for years if that happens.
Thank you in advance.
AW: [SE Live with Walkman] Installing MESA Kernel over Extended Stock Kernel
No it won't erase the ROM
See my "how to install a custom kernel/rom", there you can see how to flash the boot.img using flashtool
Sent from my Nexus 7 running Android 4.2.1
The steps is so easy,
1-Download the kernel, extcract if it is a zip file
2-Get boot.img
3-And put it in your fastboot folder
4-Open cmd and navigate to fastboot folder,
Or simply click on start search for cmd and drag it in fastboot folder then open it
5-shutdown your phone
6-hold on volume up and connect the usb from the phone to pc
7-it will ask you for drivers ( skip if you already done so)
8- in cmd run the following commands
Fastboot devices
Fastboot flash boot directorytoboot boot.img
Replace directorytoboot with actual directory
It will not earse your rom.
And btw xperia 2011 is hard to be bricked

hi. if you encounter header error ,
you must install (fastboot, ...)driver correctly
then go ahead.(its right)
this is the weird thing which i faced with my android device. i flashed to cm10.1 + lupus jb kernal. now my device keep restarting. i thought it was rom fault. then i tried jellyvanilla ex1.0. but problem was same. then i reflashed to stock rom via seus. but still my device keep rebooting when i use internet. im not sure what is the reason for it. i did everything which i can do.
anybody have any idea about this problem hope i will get a answer
cm roms need freexperia kernal. you can find the kernal (boot.img) file in the rom zip file. flash that kernel and reflash the rom.

you can try custom kernels but only those which are compatible with cm10 u can not flash a kernel that is for another rom that is stock based or on another cm based the kernel must be for cm10 only

Usually rom in zip contains kernel, so if you flash rom kernel anf then rom you will end up with kernel from rom. When you fastboot lernel, be sure your bootloader is unlocked and makd kernel you downloaded is for your device and it is right fof your kind of rom, stock cyanogenmod,...
After you flash kernel over fast boot then when you start the phone go directly to clockworkmod and wipe cache and dalvik. After that reboot and it should boot.
One exception, of course, if you want use experimental kernel, flash via cwm as it contains not only kernel but even updated libs.
