Rooted with DooMKernel v15 with 4.0.A.2.368

Hello,
I have rooted my phone with the latest DooMKernel version: v15.
I forgot to first update my Xperia arc to the newest Build-Number (with the OF xperia update) and now I am still on Android 2.3.3, 4.0.A.2.368 with the DooMKernal:
2.6.32.9-DoomKernal.
Is this bad for my phone?
Do I need to change anything or is my phone fully functional know?
edit: ok I have flashed my xperia arc with the LT15i_4.0.A.2.368_Generic Global update using the newest version of FLASHTOOL. now my phone seems to be running on Official Firmware again
I'm trying to install the newest Firmware now.. then I can (without worries) install the latest DoomKernal version?
edit2: I still can't update to the latest official update with the xperia PC updater.. why is this?? (error: the phone contains edited software that can't be updated).
do I need to flash the newest update with flashtool on my phone??

DooMKernel works perfect on the latest firmware (.42) so go ahead and install it

well that's exactly my problem, I can't update my phone to the latest firmware (.42) .. read my post
My Xperia Arc is now flashed with the LT15i_4.0.A.2.368_Generic Global update and when I try to install the .42 firmware, I get a error message that says: the phone contains edited software that can't be updated.
So do I need to flash the newest update with flashtool on my phone??

If u can instal the DoomKernel,
Then I'm sure that u have unlocked your bootloader.
As far as I know, you can't uodate via ota or pc companion if u unlocked the bootloader.
Just update it by flashing .ftf .
You can find the update on the development or general sub forum

thank you for your reply
I have downloaded this update: LT15i_4.0.2.A.0.42_Generic_Global.ftf
will flash it any moment!
Another question about the DoomKernal
I'm really losing sight here ...
So the latest version of DoomKernal is the [ARC/ARC S] DooMKernel (v15) (FW: 4.0.2.A.0.42) [ 2.0Ghz version ] .. but why is WIFI disabled??
Do I need to download another kernel, or something like a plugin??
How can I get everything to work like wifi ect..?
Edit: I found out that I have to use his modules to get the rest to work (don't know why the DoomKernal isn't complete .. but ok).
So I downloaded the ARC-DooMKernel-v15-modules_CWM how can I install/use this with the DoomKernal v15?

Install doomkernel, then boot the phone, at boot the leds will light up, hit the back button then, phone going in recovery then and then install the modules via apply zip from sd card.

HAHA IT HAS WORKED!! SO MUCH THX, from now on I love this forum!
If I have any more questions about my phone I will post it in this forum! Great Community!!

Yes, when you use the newer doomkernel you have to flash additional module to have the wifi work.
Anyway, so you also updated to 4.0.2.A.0.42. I wanted to try the latest doomkernel v15 on my older firmware but it was designed supposedly for .42. Also, I'm not sure if it will work on me because if I don't update firmware then my baseband is lower also, so dunno if the modules will work on a lower baseband. Any ideas if it will?
Also, a later firmware is going around as well : 4.0.2.A.0.58. So I thought I will just wait it out till either doomlord makes a kernel based on that, or just flash the arconium custom rom based on it, when I got the mood to do it.

[Q] How to Backup stock Kernel + ROM ?

Hello Guys !
I wanna try some custom ROM so before doing that want to backup my Kernel & ROM. If anything gone wrong so I can revert back to original ROM.
My Cell details:
Xperia Arc S
LT18i
Android Version 2.3.4
Baseband Version -64
Build number
4.0.2.a.0.62
Locked bootloader
& unrooted.
Please someone guide me....
Thanks in advance...

If your bootloader's locked then you can't back up. You can only reload(repair)it from PC companion.

Thanks sinkster !
Ok done unlocked bootloader.
Then advice the further steps...

XPERIA CWM AUTO INSTALLER
download this app and install CWM recovery on ur phone...
Then reboot ur phone into recovery mode...
TO DO THIS, LONG PRESS BACK BUTTON WHILE THE PHONE RE-BOOTS
(OR)
KEEP TAPPING VOLUME DOWN BUTTON...
After it boots into recovery, go to BACKUP & RESTORE and Select Backup...
This will create a NANDROID BACKUP on your phone exactly as it is...including apps n contacts n all other data..
you can find it in SDCARD/Clockworkmod/Backup/
Good day...

If you wanted to take a backup without installing CWM you can use fastboot to boot (not flash) a kernel that has CWM built in.

thanks amulbaby
I will try and get back here with comment ...
EDIT:
I tried that steps but it will works only on rooted phone ..., can not enter in to recovery mode by pressing any key, it normally boots up and appear home ...

Why don't you root it with flashtool then?
But for that u wud have to downgrade to .42, with flashtool before rooting

Hey I am also wondering about this. I have lt15i flashed with Official .562, locked bootloader and CWM installed via flashtool.
Which ICS roms will work with official .562 and locked bootloader? I have been searching all morning but not a lot of updates regarding this since the official .562 release.

Here is the point I was looking for these alternative . . .
I have STOCK ROM with 4.0.2.a.0.62, actually I want to backup these stuff, I read about that downgrading via flashtool and root, if I flashed via flashtool that STOCK ROM will wipe...
Anyway here what I did to make a copy of my stock firmware & upgraded to ICS firmware & rooted.
Repaired my phone using Sony update service to download and backup STOCK firmware
Flashed with flashtool official firmware LT18i 4.1.A.0.562 NCB Icecream Sandwich Official

First you need to download a kernel that has cwm built in, I would search for recoveryARC.IMG then you also need fastboot from the SDK.
All you would do is connect your phone I'm fastboot then run in a command prompt fastboot boot recoveryARC.IMG. Your phone would then boot using that kernel and you can enter cwm by pressing the vol down several times. This process wouldn't flash your kernel only load it temporarily.
I would try and find a guide about them but I'm on my phone.
Sorry just noticed you've already done it, congrats enjoy ics.

Thanks bro ...
I already upgraded, anyway I want to know the process, you mentioned here this process wouldn't flash kernel only load it temporarily, I am confused...
Could you describe in details .. ? Actual what happens if we flash recovery img...

Well you can use fastboot to install the kernel which overwrites the previous one, or you can use it boot the kernel which just sends the kernel to the phone which the boots and temporarily uses the kernel. However when the phone next shuts down it will return to normal use.
If you flash a kernel it writes the .IMG to the boot partition. So if I wanted to use a kernel that stayed between reboots I would use 'fastboot flash boot kernelname.IMG'
However if I was running stock I could use recoveryARC.IMG with cwm, and do fastboot boot recoveryARC.IMG then run update.zip as normal. Then all you have to do is reboot, you'll be back to stock but the update would still be installed.
Sorry if it's not cleat, the best I could do on my phone.

Can you please give me details on you did this? It is precisely what I want to do (ie. Backup the stock carrier rom on my Xperia Arc before flashinging an old ROM in order to root it).
Did you use the "repair" option from "Sony PC Companion 2.1>Support Zone>Phone software update>repair phone"?
Or did you use the software from here: http: // w ww(dot)sonymobile(dot)com/gb/tools/update-service/
Can you please tell me the whole procedure on how you did the backup of the STOCK ROM? Thanks!

ROM backup OK; How to take backup of Kernel
I am using Sony Xperia Ray ST18i
used it for a year with stock kernel and ROM
rooted it long ago, but was afraid of custom ROMs
last month I unlocked bootloader, flashed ROM and custom ROM (beanstalk 4.3.075), enjoying it but obviously not so stable like stock
Now if I wish to move back to my stock kernel and ROM
what steps are required.
I suppose
1. flash the stock kernel
2. restore from backed up ROM (I do have nandroid backup of stock ROM)
but how to achieve the step 1, as I learnt nandroid backup doesn't backs up ROM.
My collegue is having same phone still on stock, Can I use his phone somehow to extract kernel. I searched and found a zip to be used through CWM which backs up kernel it was meant for some samsung phone I tried but failed.
Thanks in advance.
Do I need to supply some more information to get help?

Did you removed some system app's?

no , just used link2sd app to move all app files
i think its may be the problem

Solution
If you have the .42 and you want to get the .62 root you have to do this:
- Flash with flashtools the .42 original room
- With flashtools root your phone.
- Start updating via OTA to .62
If you have 0.42 and you root this with superoneclick or other that not be Flashtools you wouldn't get your .62 root OTA

aaah thanks , i just want to update to .62 so i be ready to receive ICS when available Nothing else :S
but i think i will be wait when availble official to Arc (not Arc S) i will flash it via flash tool

I recomend to you installing ICS version of ARC S and then flashing the Doomlord kernel for setting the correct CPU clock. (only for unlocked bootloaders).
But... well ok, if you want to wait to the official version you can see very good changes from .42 to .62, better battery life, more stability at the system running, etc...

the feedback of arc user says that is was some problem with touch due to different kernel even with arconiume ICS rom
i think i will try unroot we zurg brush (winch i root first) and root again with flash tool )
and try to upgrade from ota

oka
i found link for .42 but its 150 MB unlike the other link which is 250 !!
i found the first link in http://forum.xda-developers.com/showthread.php?t=1330314 topic
and uploaded.to server is suck so i search for another link like hotfile cause i have premiuim there

Yes you can use that, but you must flash this kernel after you flash that stock firmware to root.

By the way, you can not root .587 you have to download .562 or like mentioned before just flash 562 kernel, root and then flash back to 587 kernel. But I think easier should be to download .562 firmware and then just root.

The easiest method is with an unlocked boot loader, install 587, flash CWM'd Kernel, flash Root.zip, done.

yes. (& personal data also, so make backup) but root is a easy job (1min) you can root phone with ''e-root'' app. btw if u plan to use custom rom , then no need to root it all custom rom/kernel is prerooted....
if not you can extract kernel & try flashing i manually..
