[Help] Bad Boot Loop :( - Xperia Arc Q&A, Help & Troubleshooting

Hey guy's,
i unlocked my bootlaoder, rootet my phone (LT18i) and flash the ArcKnight Kernel. After that i've installed THIS ROM. Everthing works fine, great Rom but not fully translated yet, so i want to flash another Rom until MIUI's is fully translated. I Flashed CM9 RC1. But it won't boot....now with every Rom i try to flash i came into a boot loop -.-
What is wrong, i'm frustrated :crying:
Only thing that works is to flash the Orginal Rom from sony via Flashtool, but Sony Roms suck.
Yes i wipe cache/factory reset and all this stuff
PLEASE HELP ME :crying:

Have you changed kernel while using CM9??

before flashing CM9 make sure to flash its default kernel (FXP) because the stock kernel wont work with CM9 and will lead you to bootloops
just flash the kernel > in CWM do the necessary wiping (make sure to wipe dalvik cache to) > and re-flash the ROM

okay thanks, i don't knew that. I'll try it and tell you if it works

ok nice, everthing works fine. Big thanks to both of you :good:

Cyanogen boot loop

i have googled this and tried multiple ways of installing it but i always get a boot loop. Whats going on?
Hey if you just want to get your phone back again, just flash another firmware from the one you used. Should start up just fine.
have done already but i actually want to install cyn mod. I managed to get as far as the main screen buit then immediately reboots. I cant find wifi modules for latest doom kernel either they arent in his thread.
FLASH KERNEL FIRST (from cyanogenMOD or doomkernel for CM7 etc)
Than flash cyanogenMOD
any other way will make your phone bootloop.
I think you have to unlock BL via SE in order to flash CM..
of course you would likely broke your warranty.
this based on my experience (I'm a newbie too in the android's world). this is what I've done :
1. unlock BL via SE (not all carriers allowed this!)..
2. flash .42 fw
3. follow the instructions given on CM thread by fxp.
it's worked for me.
goodluck.
I've had this problem before. Did you wipe the delvic cache, wipe data/factory reset and wipe cache partition in CWM before you flashed the update.zip?
It would seem it was a specific version of cm that was making it bootloop the one from dooms thread 7.2.0 works fine and also the one before the latest stable release also worked fine. I however found a problem with the spacebar on the keyboard when using the phone in landscape so am now going to try arconium and doom kernel its a shame really because cm from what i used of it looked really nice.
Try 7.1.0.1.
I got bootloop too with 7.1.0.2

Aye thats the one i used but ended up having a problem with the spacebar not working in landscape so am on acronium now which is all good but superuser keeps crashing meh always something eh.
at first im also having the same problem,just follow the instruction by FXP : flash bb56,flash fw.42,flash FXP kernel via fastboot,flash update via recovery,wipe dalvik cache,reboot..

I have this exact same problem
I've done everything I was supposed to, I think, and still doesn't work. It boots, shows me the little Android "Welcome!" screen, and before I have time to press anything or begin setting up my device, it reboots into the Cyanogenmod loading screen. I've tried different kernels, different basebands, every time wiping Dalvik cache, etc. and it REFUSES to work. I'm pretty desperate by now because I really wanted to use this ROM so any help is greatly appreciated.
I also followed precisely rashid.fairus' instructions and it still does the exact same thing.

Sometimes you DON'T WIPE ANYTHING AT ALL. Just flash CM and Google.
Works for me on Xperia Acro S.

Only when you upgrade to a later version of the same ROM.

Wipe dalvik and cache when upgrading to later version, wiping data will reset phone to factory settings and you lose all personal data.

[Q] [Help] stuck in boot loop

Help me Im stuck in boot loop.. Before this I flashed Merruk kernel 2.0 and creeds 3.2. It works well but after I flashed back to stock rom (DXLA1) I got endless boot loops. Can someone help me T_T
If you have a backup of your creed's fusion with merruk kernel, then restore it via CWM. Or else you'll have to flash back to stock rom via Odin. But first try flashing back to stock kernel.

firstly, make a backup of your system by CWM,
it is useful;;;;
Remove battery wipe cache factory reset wipe dalvik install new from e.g. creeds 3.2 .

[Q] Xplay won't boot except into Recovery

I have a r800i and when I try to boot it with DoomKernel ICS v0.3 it always boot into the recovery even though I have a room installed.
I installed xDark ICS by opening the zip. I also did a factory wipe, wiped the cache, the debian one, but it still only boots into recovery. When I used DoomKernal v14 with the NXT rom, it boots fine although I can't enter recovery (so I can't patch the wifi). Using the default ftf everything works normally.
Any help would be greatly appreciated. I've also search the forums for similar problems but I've only found similar problems with other phones using other kernals and roms.
I am having the same problem, except I cannot even get at recovery, it just sits at Kernel splash screen. Otherwise I'd have restored my nandroid backup already.
I flashed ics doomkernel, factory reset, wipe cache and dalvik then flashed rom in CWM and now my device is stuck.
Bootloader unlocked r800a
Can anyone help us two?
Sent from my backup x10 using xda premium
:highfive:Both cases sound like bad flashes. For the first post I'd say CWM restore it and try to reflash. For the second post, I'd say use flashtool on your pc and flash a stock rom again.

[Q] Boot Loop, Need help!

i have been running the kiss kernel for a while now, last night i tried to flash the hellboy kernel and retern to my pacman rom. but it still boots, i have cleared all my caches formated everything but my sd card, have tried flashing all kiss kernels and multipul hellboy kernels, but never gets passed the boot screen.. any ideas?
i managed to get it to the android is upgrading.. starting apps thing, but it gets stuck there.
Did you wipe anything when you flashed the kernel? If the kernel was for jellybean it shouldn't hang like that... not sure?

im with telus gsm. the rom was working fine, but i went to change the kernel to hellboy cause i herd it was a bit better and now im in this bootloop
also not running the newest version of that rom, i am running v15a
Oh okay wellllll I'm on virgin mobile and I don't know much about the primou phones and rom and kernel compatibility so I'm afraid I'll have to leave this to someone who knows more... good luck to you though... maybe try booting into bootloader from the recovery and flash the boot.img you had before then flash the rom again?

yeah i always wait a little while, i have chosen latest kernel, has not made a difference, i have gotten better results using an older one of the titanium kiss, hellboy doesnt seem to work with my phone for some reason
Did you use the command
fastboot flash boot boot.img or just
fastboot boot boot.img?
Also,after flashing it,does the terminal say something like this?
Okay.
Okay.
Finished.
Edit:also,see that you are flashing the kernel in the fastboot screen(where it says 'fastboot usb'),and not in the Hboot(bootloader) screen.

i am using the all in one tool kit to flash my kernel, yes i am in fastboot, a window pops up runs through code and my phone reboots, i have changed the kernel on it before, but for some reason this time it wont boot properly at all, the phone is currently at the " android is upgrading" screen, it was the starting apps box with the spinning circle
if you say that it is stuck at android is upgrading - that's because the dalvik works and it is deodexing your gapps.
so i suppose you flashed kernel, flashed rom and gapps and rebooted. well this works from time to time but you have to reboot between flashing rom and gapps.
1. download this kernel: hellboy
2. go to bootloader and flash the kernel.
3. go to recovery and: do a factory reset + wipe system - no need for wiping dalvik or cache cause factory reset does them both.
4. flash your rom
5. reboot.
6. if it boots properly, reboot to recovery and now flash GAPPS package.

I have tried with flashing stock kernel but nothing happens please help... i want to install custom ROM
Have you formatted system, data, cache partitions? I had similar problem with flashing a stock based rom because of such a stupid mistake.

Formatting /system on locked bootloader is the stupidest thing to do (I guess). You basically delete the Recovery and get in trouble.
You guessed wrong because some stock based roms require system partition to be formatted and not doing this caused some serious problems for me also flashing back to stock with flashtool is like pushing one button and then waiting for 5 minutes for flashing to complete so I don't see a problem here.

I have done every time these steps.
Factory reset
Wipe cache
Wipe delvik cache
Format system
Install rom from cwm.
Again clear cache and reboot gives me stuck at sony logo
I take it your phone as it should if you install stock ftf try ultimate hd just out of curiosity

I think I see a cause of your problems now... your rom is .431 but two of these roms base on .587 firmware and third one requires a custom kernel so try again with .587 kernel and report if this helped.

So please can you tell me the correct sequence to put custom rom....?
1st install kernel and then rom or or install the rom and then kernel?
It would be the best if you could unlock your bootloader but if you can't or don't want to then:
Download and flash this https://www.dropbox.com/s/957gfo1kaf7pefe/LT18i_4.1.B.0.587_(1254-2716).ftf (its stock untouched .587 ftf for arc s that I've used many times)
Root then install CWM with x-parts
Reboot to CWM format data cache system and dalvik cache
Install your rom
Reboot
And remember that you can use only stock based roms so racing bean wont work.
