Boot keeps restarting :(

i was rooting my arc s and it was successfully rooted after that i wanted to install some custom rom on it, i tryed the Modded ICS one and installed there boot.img and now my phone just reboots after it shows the "XPERIA" logo
Please help im new at flashing )
Thanks

hi
So u have flashed boot but not rom?
U need to have the rom on your SD .
Turn off phone boot it up and when boot logo appears repeatly press back button (not sure if there's an indicater on that kernel or not)
This should boot cwm when in cwm make a backup
Select backup and restore then backup
When this completes wipe data ,clear cache and advanced clear dalvik cache
now select install zip from SD ,then choose zip from SD,then locate your rom file select it and hit yes when it finishes ,reboot and enjoy
Volume rocker moves up and down
And home or power button selects
If u can't get into cwm u have made a mistake flashing boot so reflash it before the above
Failing this return to stock by flash original fw thru flash tool
Plenty of tuts on that just search
Hope that helps

is not the solution,i try several times,and always the same results.

Try:
1) copy your rom into sdcard.
2) flash your kernel under fastboot mode, then reboot.
3) keep press volumn button while rebooting, it should b under cwm screen.
4) wipe dalvik cache under advance
5) wipe data partition
6) factory reset, then reboot again
7) go into cwm screen again, then choose install zip frm sdcard, choose n run the rom that u copy into sdcard earlier. Reboot again after completed.
8) u shall wait for a while when restarting... Then should b ok....
U may try this, dunno whether work for u not.

Reminder:
For mooded ics rom, U must use ics stock kernel or doomlord ics advanced stock kernel, its run quite well for me...

I flashed my arc s last night with ICS Kernel with CWM Recovery and JJ's rom, had the same problem but as the above poster mentioned, wipe everything sorted out the problem.
Note: Just factory reset not enough you have to wipe everything

[Q] About flashing cm7

so i did was
1) download cm and googlepps
2) extract the boot.img to x10 lib in the flashtool folder
3) connect phone in fastboot mode flash the kernel
4) reboot phone went into recovery mode
5) wipe cache wipe dalvik wipe user wipe batterystats
6) install through sd card zip
7) reboot into system
and my phone still bootloops anything that i have done wrong? Bl is unlocked, phone rooted.

If it's the last version of cm7 try an older version of kernel. I always flash kernels with fastboot and till now never got problems.

Told ya...

[Q] [Xperia S] CM10 Installation problems

Hello.
I was running cm9 for a few months without problems. But since the update from Januari the 13th apps started crashing.. I then tried to completly reinstall (wipe everthing), but got stuck on bootloop. Then I thought lets try cm10, and also I get stock on the booting screen.
These are the steps I did.
Flashed LT26i_6.1.A.2.50_1257-5499_WORLD.ftf to go back to stock rom.
Went trough the wizard and all and let it settle down for a few minutes.
Shutdown.
Fastboot boot.img from FXP202-cm-10-20130110-UNOFFICIAL-nozomi.zip
Fastboot reboot
Enter recovery
Flash rom FXP202-cm-10-20130110-UNOFFICIAL-nozomi.zip
Flash gapps gapps-jb-20121011-signed.zip
Wipe cache
Wipe dalvik
Reboot system
But it never boots, I get stuck on bootscreen (same procedure I did with CM9, but also got stuck on bootscreen),
What am I doing wrong?

Try doing full wipe and reinstall CM 10 as you did previously

Follow this thread for Kernel and Rom installation; http://forum.xda-developers.com/showthread.php?t=1879982
Follow this other to select your Rom; http://forum.xda-developers.com/showthread.php?t=1642480
And take that cm-10-20130110-UNOFFICIAL is CM 10.2 for such reason look for JB Gapps For Android version 4.1.2
I flashed the Rom very well, also the kernel. my problem were the Gapps. I see there that you do not have the correct gapp zip for cm-10-20130110-UNOFFICIAL;This is CM 10.2 after installation and you need a 4.1.2 JB Gapps. Try and repeat the process.

I do have the correct gapps. This CM is android version 4.1.2. Here I downloaded the latest for CyanogenMod 10.0.x which is for android versions 4.1.x.
Anyway after a whole evening/night of flashing I finally managed to get it working via hei1125 cm10 version:
http://goo.im/devs/hei1125/nozomi
I dont know what I did to make it working again, but it does.. CM10 does look a lot nicer then CM9. Although I heard it has some bugs, which yet I still have to encounter..

Hello,
I have a problem updating my nozomi (xperia s) to the newest cm version. I always get error 7 - some symlinks failed and i cant install an update without factory reset / wipe user data. After this step i can install the zip, but without wipeing, always the same error.
When i'm installing updates on my girlfriend's urushi (xperia ray), everything works fine.
Any ideas?

Enable signaturecheck in recovery before install. It worked for me.

It's always recommend to wipe all (cache, davlink even system) then flash.
Be sure to mount system and then try.
And of course, check is you zip file o.k (maybe download again)
Even if you updating cm to new version it's best if you wipe.
I know that's lot of work, but only then you'll have good battery life, smooth and fast ROM and stability.

Reinstalled apps and Data from googleserver after a datawiped update shoudn't be a Problem, or?

I had just the same problem today. I installed cm10 from recovery and did everything you did!!!!
What i did to solve this prblem is:
- Went into recovery.
- wiped cache and dalvik.
- flashed the latest CM10 (FXP215 to be precise) again!!
- flashed gapps again!!
- after flashing both zips I wiped dalvik and cache again.
- Than reboot.
If you keep getting into bootloops, keep doing these steps. Beliefe me man I had the exect same problam today and this solved it . Just dont panic or do something stupid and have alot of patients! :good:

But this is not a so called clean install. I use factory reset to have a clean install or just wipe data partition. After 1st boot I restore only some of my saved data with titanium backup.

[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.

[Q] Boot loop after flashing TWRP recovery !

Hello everyone, I have a problem with my xperia S, any help would be greatly appreciated! Let's start from the beginning, I'll try to be brief :
So, I flashed TWRP recovery using the app "RASHR" (I was using the Pure AOSP Lollipop rom when doing this, if it can help), which caused my phone to always boot the recovery and nothing else. I managed to flash the rom again (I made sure to wipe using "factory reset" and "dalvik cache" before installing), and it seemd to work perfectly, but then I rebooted the phone, and got stuck at the sony logo, no recovery available.
I flashed TWRP recovery (stock-6.1.A.0.452-twrp-2.4.0.0.elf) using flashtool, then tried to install another rom (Paranoid Android, found on this thread : http://forum.xda-developers.com/showthread.php?t=2573345). The first boot was successful, but as soon as I reboot the phone, I'm stuck in a bootloop again, with a little difference : when the sony logo appears, the led becomes pink for a few seconds. No access to recovery. Then the led lights off, the logo disappears, and the phone reboots. Again and again. I just reinstalled the same recovery and tried to wipe and fix permissions, but it does not solve the bootloop, and I don't know what to do...
Could it be possible that "rashr" did a bad install of TWRP and corrupted my recovery/bootloader partition or something ?
EDIT : I reinstalled Pure AOSP Lollipop, and now for some reason, no boot loop anymore... I don't understand why, but as long as it works... problem solved !

Hello, and thanks for the answer ! After a few days using the Pure AOSP rom and rebooting several times without any problem, I just got a bootloop again yesterday, forcing me to reflash my rom to be able to use the phone again... will your method (including your tutorial in your signature, which I'm trying as I write this) solve the problem once and for all ? It's a real pain to redownload all my apps again and again and again because of those bootloops =(
Edit : finished following your tutorials, everything seems to work for the moment, hope it will stay stable this time... thanks for your help )

What did You do before the bootloop was caused? Did You try to flash the TWRP again?

No, I didn't, I was too afraid of creating another problem xD I just used the phone normally, installed apps from the play store, the last one being nova launcher (but I rebooted a few times after that without any issue)., things like that.
But after applying your tutorials to flash the Lollipop Pure AOSP rom, I think the problems were caused by :
1) a wrong recovery and/or flashing method : previously I used "stock-6.1.A.0.452-twrp-2.4.0.0.elf" which I flashed directly via flashtools with the phone in fastboot mode with the command "fastboot flash boot xxxxxx.elf". And although I didn't reinstall it after flashing the ROM, I suppose it left something in the recovery partition that caused the bootloop... ?
2) the fact that I didn't flash any "boot.img" at all before installing the ROM... inf fact, I didn't even knew it was necessary !
3) a bad ROM installation procedure : wipe, flash rom, gapps and SuperSU and THEN wiping cache and dalvik, restart
4) all of the above (!)
Anyways, after doing it "the right way", everything seems to work correctly for the moment. After installing the ROM, I followed your recovery tutorial using "openrecovery-twrp-2.8.5.0-LT26i.img", hope I did the right thing this time, hahah. Thank you again for your help !

Glad that it is worked for You. Yes, You did somethings wrong, which caused You bootloop, better explained as below:
1) The "stock-6.1.A.0.452-twrp-2.4.0.0.elf" is the stock kernel of ICS version of Xperia S. So if You flash it with a ROM, Your ROM won't boot.
See, each ROM consist of two main parts, one the kernel and other the is the remaining of ROM(apaps, data etc.) A ROM is compatible only with certain kernels, and if wrong kernel is used with a ROM, the ROM won't boot. This is what You were doing, using a stock kernel on non stock based ROM.
2) This essentially doesn't lead to boot loop. This step needs to be done sometimes if You occur a error while flashing ROM via TWRP sometimes.
3) Yes, this sometimes does cause issue, the procedure is always for a clean flash, -Wipe system, wipe data, wipe cache and wipe dalvik cache. Flash ROM and immediately wipe cache and dalvik cache.

I guess You are on stock firmware and flashed the "stock-6.1.A.0.452-twrp-2.4.0.0.elf" or the twrp.img file via fastboot directly. Flash the DoomKernel from here via flashtool as kernel and it will work with stock and have recovery too. Use the blue coloured "Download Now" button and the extension of file is .elf.
