[Q] Stuck on Doomkernel Logo

Hi again.
Today I unlocked my bootloader using the official website.
This deleted my /data, which was kinda bad because i deleted stock home.apk and had golauncher installed.
so when i booted up i just got blackscreen + statusbar, nothing too bad i though.
i wanted to install doomkernel and arconium:
i flashed 36 (?) baseband and libs
i flashed doomkernel + modules
i installed arconium 7.1 with cwm (installed with the cwm app from the market when i had locked bootloader)
i only got the doomkernel logo, nothing happens.
i cleared dalvik cache and did a factory reset, still stuck on logo.
i can still access cwm but i dont know what to do now.
i read the guides, followed everything but i got stuck on this.
some help would be really nice,
thanks in advance!

Flash a complete stock firmware(.62) with flashtool, boot into that. Re-download/transfer the arconium zip, fastboot dooms kernel, factory reset/cache wipe, then arconium in cwm. Once you have that up & running then flash lib files for .36 etc.

U should not have flashed Arconium on the locked bootloader directly.. Dont just run through the steps anyhow.. Search the forum and get to know the steps properly.. Download some 0.42/0.58/0.62 firmware(.ftf) file and flash it using the Flashtool. After that u better flash the DooMKernel on the unlocked bootloader by using the boot.img.. Search the forum for that again.. U'll easily get a "How To" about that.. Once u r done with the kernel flashing, copy the Arconium zip file to ur SDCard and flash using the CWM.. Good luck...

nono, i unlocked the bootloader before i flashed anything
the chain was: unlock bl, flash 36 baseband, doomkernel, arconium
i read the threads 2 days before this like 3 times, but somehow i still missed something :/, well works now!

okk... Glad.. its working fine now.. And always remember to wipe cache/dalvik cache whenever u flash a kernel or other updates.. Cheers!

[Q] Peculiar Problem with R800i boot

Hi guys noob to these forums so bare with me,
I have one of the first ever revisions of the r800i fully unlocked etc. I have been using Cyanogen Mod 7.2 on it for months now with the free xperia kernel (cannot tell you which version all i know it is one of the very early versions) but I have now decided I wanted to change to another ROM however my kernel will not allow any other rom, it just boot loops. I managed to get DoomLord's Kernel for ICS 4.0.3 Alpha to work, with ICS 4.0.3 but that is the only kernel which will work. CM9.0 kernel just freezes with a pink light :/
Also any other dark forest kernel or doomlord kernel just boot loops too.
I also tried installing a clean version of CM7 and that just doesnt boot for its life, I have to restore my backup image to get anywhere, with my original kernel as i cant even get into CWM with any other kernel except for DoomLord ICS (and my original of course).
I did have the 36 firmware installed but since then changed to 42 and 62 (finding 42 to work best signal wise).
If someone could help me it would be appreciated very much.

Yup, been getting the same problem. I was only able to use the first ever version of DoomKernel for the Play but couldn't use any version after that as it always resulted into a recovery loop - Boot up phone, at boot logo shows blue light and goes automatically to recovery, try to reboot and same thing happens again.
Can't even use Keiran's kernels which use Doom's sources. :/

have you tried
Code:
fastboot -i 0x0fce erase boot
followed by
Code:
fastboot -i 0x0fce flash boot boot.img
The first command erases the boot partition, the second command flashes a new kernel (I don't know if it'd help, it's just an idea, and it can cause troubles, if you don't flash a new kernel)

ok thanks I shall give that a try

Still does exactly the same thing :/

Have you guys tried using either wotanserver or flashtool to flash back to stock then fastboot a new kernel?
(Both work with unlocked bootlaoders, well, I've tried wotan with a test point unlocked, I don't know about legit unlocking...)

I've tried it with Flashtool but doesn't work.
Sent from my R800i using XDA App

I get exactly the same thing using this software. I use flashboot in general anyway, I find it ALLOT easier than using fastboot itself, just can't seem to get my head around this problem :/

Have u tried the 1.6ghz version? What about doomlord advanced stock?

Tried both and same thing happens.
Have also posted about this in DooM's thread.

[Q] Arc Not Booting :( [RESOLVED]

OK, I Know I did a very stupid thing but I flashed the Nordik Version of the Official ICS Rom for Arc S on My Arc.
Now The problem is when it was flashing, the flash stopped at a certain point. Here is the message
14/002/2012 20:02:24 - INFO - Flashing userdata.sin
14/002/2012 20:02:24 - ERROR - Error flashing. Aborted
14/002/2012 20:02:24 - INFO - Now unplug the device and power it on

But then After I Rebooted, It showed the sony logo for a second and then some logo of the mobile with a caution symbol (Yellow Exclamatory Mark). And thats it, after a couple of seconds, it switched off.
I repeated the process and the same thing.
Scared Then I Flashed a Doom Kernel and did a factory reset. While the factory reset, it said that it could not open \data :|
i tried formating data many times but it could not mount it saying different file system.
So I flashed a matching Custom ROM and It does not work, Nether is any app installing nor any file getting saved
Please Help!
And Anyway to solve the /userdata filesystem problem?

If flashtool stopped then try re-downloading the file in case it was corrupt, and try to re-flash. If that's not successful download a stock 2.3.4. ftf and flash that.

FTF Wasnt corrupt :\
Now I Have tried flashing the 2.3.4 Android aswell BB 48
A Very old one which I downloaded around december time to root my Arc.
That doesnt even go past the SE Logo
The Custom ROM atleast booted.
My Guess is that the userdata partition has a different filesystem than the one it can read :\

Think it's to do with flashtool being unable to handle ICS data parameters. Binary has posted some type of workaround till he updates it.

Ok, Will check them out.
Thanks!
In his post?

think so, it's mentioned in the thread.

Nope
It stops while flashing the system.sin file

Anyway to solve the /userdata filesystem problem?

Not yet, apparently. I use cm9 so don't really know, though I think there's a cwm flashable ics stock.

No Use of that

Try connecting in fastboot, and use the erase or format commands, e.g. 'fastboot erase boot' or erase system, in case it's a system partition issue
Then try a kernel and rom.

OK, Apparently the problem was that I was using an old version of the flashtool (0.5.8)
I downloaded the latest 0.6.9.1 and followed the 3 step flasshing process

Hi guys , Please help me as I have tried multiple kernels and roma all of them exhibit same issue,
Booting to CWM using the CWM inbuilt into the kernel takes a long time as well as once a rom is installed via CWM it completes installation and then comes to the boot screen and it sits at the boooting screena and does not get past it.

How are we gonna help if you don't state ROM and kernel and what exactly you did.

[Q] HELP What should i do? if i got stock in TWRP recovery

Guys what should i do if my r800i got stock in TWRP recovery of "LuPuS-PLAY-jbv8-720"? Please help. :crying:

You mean stuck? Is this on the main screen on TWRP or was you trying to do something?
Does CWM work (Press vol - instead of vol + on boot)?

If it's stuck in TWRP recovery just take out the battery
Also you should use CWM if you're having problems with TWRP, hold down the other volume button on boot to access it

Yes sir i mean it stuck when after i flash turbo v1.3 and LupusJBV8 i got stock..

Bravo, RTFM, guys! Turbo and Lupus use custom partition layouts, but rheyre different. To move from stock or turbo to lupus or vice versa make CWM backup, flash new kernel, restore backup.

bootloop Xperia Arc S LuPuS anzu Stock-gB+iCsv16-full and xperia ultimate hd 4.0.
Hi, I have a similar problem with LuPuS anzu Stock-gB+iCsv16-full and xperia ultimate hd 4.0.
Xperia Arc S - Unlock Bootloader -
I installed kernel and the Flashed the ROM and then it went to bootloop i can access to the CWM but it just show the screen whit the logo and nothing else, no options, nothing. also i can't get into the flashboot when i try to flash a new kernel or ROM with flashtools it doesn't recognize the device because when i insert the cable the bootloop starts automatically and as i said flashtools and windows don't recognize the device i'm a little worried because most of the unbrick tutorials rely on getting into flash boot mode
hope you can help me

HELP xperia play kernel bootloops and freezes

hello there my names kyle and im new here but you can call me sangy, anyway i have joined the site to post this
i have had my play now for 6 months and i want ics and a new kernel, i heard lupus was the best one so i flashed lupus using fastboot and the correct rom. i have followed all steps correctly and the dam thing just boot loops after 1 min of booting unless i have my usb in my pc at which point the phone will stay on like it should without a single bootloop. so with a potentially bricked phone i flashed the stock firmware back v4.0.2.A.0.58 and re flashed a different kernel and rom still the same issue so i flashed back to stock again. if anyone can tell me how to solve this weird ass issue i will rate you +1 because im getting sick of having no cwm and incompatibilities with apps and i want to overclock
ps im planning on flashing doomkernel v14 hope this problem is gone but i know it will have the same issue.
my phones current state is this
xperia play r800i
stock kernel(2.6.32.9-perf) [email protected]#1
FW 4.0.2.A.0.58
baseband 64
android 2.3.4 ginger bread with root and unlocked boot loader
thats everything i know thanks for reading and helping in advance
edit: sorry if im not been precise but by boot loop i mean hot boot where the phone will run fine for 3 min then freeze and reboot on its own until i pull the battery or plug in usb in pc upon hard reset it even does this in kernel boot up

which lupus kernel, ics+gb v7 or lupus ics beta v12. have you tried flashing through flashtool because it always works for me and which ics rom as their are tons.

hello thanks for the quick reply
ive tryed the lupus ics+gb kernel latest version with the ics beta rom for xperia play and ive also tryed the lupus gb kernel latest version
and yes i have flash tool and all the drivers but a nice reccomendation on what to flash next based on my phones spec at the moment would be nice
also why am i the only person on the internet with this problem? ive heard of having 60+ apps on the sd to cuase hot booting but for me this is just out of the ordinare, particulary when ive whiped all the phone and flashed a new kernel.

With Lupus kernel, use R800i_4.0.2.A.0.79 firmware

will be flashing that stock firmware now over my other one then put lupus gb+ics over the stock kernel
will let you know if it goes well and fixes this

unfortunatly it did not fix it rom loads up, gets to the regular sony setup then freezes and hot boots. did this with lupus kernel ics+gb and the 4.0.A.0.79 firmware you linked me to. its either the kernel or my phone

just tryed doomkernel v14 with your FW kernel still crashes and reboots, is there something i have to do in flashtool because
every kernel ive flashed yet has the same issue.
note i can get a catlog app whilst it is plugged in then unplug it and wait for the crash and send it to you and you can see where its going wrong with the kernel and tell me what to do
thanks for reading these updates and sorry its taking this long to find and fix a big bug :good:

Did you tried any other ics/gb rom? Wipe your system/data from recovery before installing (and by installing i mean install from recovery with "install zip from sdcard")
Ps: maybe its stupid question, but is your sdcard full??? How much free space on it?

what recovery? this is an xperia play they dont have a recovery on stock kernels thats why im flashing one and no my sd card is not full
literally after i flash the kernal and boot up it will freeze and hot boot. the rom doesent factor in this. ive tryed 4 kernels so far the one that comes with cyanogen mod 9 and the 3 mentioned above
would flashtool logs be helpful if so tell me how to record them to a clipboard and you can see whats going on during the flash

For Lupus kernel - when powering on, keep pressing volume down for clockworkmod recovery or volume up for TWRP recovery.
Flash ROM from recovery that match kernel. Lupus ICS/GB V7 is for ics/gb roms based on stock (Sony) roms. Read in ROM's thread which kernel is recommended
With flashtool you can only flash .img files and in Xperia Play case, that is ONLY ics beta rom (but almoust all kernels come in .img format - so Flashtool is used to flash kernel). From recovery you can flash every other rom that you can find (just make sure that kernel match rom or else you'll get kernel bootloop)

ok this will be crystal clear
i can flash the kernal but even when booting the kernal and going into recovery to even flash a rom it will freeze and hot boot
meaning i did everything correctly with flashtool to do the kernel and with just the kernel installed (no rom) it still freezes and hot boots
as soon as i can stop these kernels from freezing i can flash whatever ics or gb there is in recovery
note: what are your settings for your flashtool as i might be missing a setting also the info from flashtool says at startup to disable MTP for 2011 devices, would this be my problem?

what kernel are you trying to flash? Be specific!
What rom are you trying to flash?
Disconnect phone from PC after you flashed your rom (any one, first boot must be done while disconnected)

the kernel i would like mostly is the lupus kernel
i can flash every kernel no problems, its the fact that the kernel crashes etc i can also flash the correct rom using flashtool the same thing happens
the case im trying to make is that you first install the kernel then flash your rom in recovery then the extras like wifi modules to the kernel
the kernel (dosent matter which one i try for my device ) has the hot boot issue happen to it no matter what i do before i even have a chance to install the rom(again the correct rom stock or not).
and yes i know you have to wait for boot ups on new roms and kernels, this isnt the first time i have flashed roms as i have a galaxy tab 2 running cm10 for the most part.
again thanks for the quick replys but i think this will require more technical solutions or debugging with my phone or software.

Install cwm on your phone. Search xparts on play store. Go into recovery and wipe system and wipe data and cache then turn off your phone. Open flashtool. Hold search while plugging your phone in and then flash kernel

did these exact instructions but the new xparts dosent work so luckily the community had the older version that works,
followed everything buy the book installed cwm using xparts after root went into recovery, wipe data factory reset, wipe cache partition and i even wiped the dalvik cache, flashed the lupus ics+gb kernel booted into the custom lupus recovery (scrolled through the menu a minute) then as expected kernel crash followed by hot boot
any other ideas?

-Start flashtool, enter flash mode, hold back button on phone, connect to pc and flash .79 firmware. DO NOT BOOT INTO ROM!
-Disconnect phone and connect again in fastboot mode (hold search button while plugging it back)
-Flash Lupus ICS/Gb 480p or 720p kernel
-While still in fastboot mode, double-click file name "start.bat" from where you unpacked file in attachment.
-Disconnect phone, power on and keep pressing volume down untill you enter recovery
