Xperia Arc Boot Loop

I own a Sony Xperia Arc (purchased on June, 2011) and it doesn't work anymore without any explanation.
When I turn on the phone, it appears Sony Ericcson brand and then, mobile network carrier brand, but then, instead of appearing home, it appears again Sony brand and an infinite loop goes on.
At first,I tried to solve the problem with the Sony tools like PC Companion and Sony Update Service.
Then, I tried to do a hard reset (back + menu and power), but nothing changed (the same bootloop).
What would you do now? Would be useful trying to flash some firmware? I have been reading posts about flashing firmware, bootloader unlocking and rooting Xperia Arc, but I don't now really what would be the best move now.
For your information, I haven't applied any kind of official upgrade before, neither I have tried to root the phone or flash any custom firmware, so I had my phone as it came from factory (with Android 2.3.2). Moreover, I haven't installed any suspicious application, just typical apps like whatsapp and so on. By the way, the phone haven't suffered any crash neither wet.
I have attached the log I have taken when I try to turn on the phone (I get the same log again and again, at the end of the log it reports some problem with memory, I hope it's not a hardware problem):

Hi,
also have the same problem.
I have the same problem.
İ have lt15i firmware. Try to install lt18i via flashtool and something broken and aborted. I tried to install LT15i_4.0.2.A.0.42_(1247-1041).ftf via flashtool. It said flashed but said power on turn on unknown sources and devices. When i try to power on it boot loop in Sony Logo.
I try to use CWM mode. Wipe and flash some data. Couldn't find user data files. Installed a Custom ROM when a boot animation appear its boot again to SONY logo. what should i do?
Any ideas?

In the end, I could fix the problem flashing the latest firmware with Sony Update.
Anyways, thank you very much for the advice

[Q] Is my Arc S bricked? update: solved

Hi guys, i have a question, i have a Arc S with stock ICS so i tried to root it (flash the 4.0.3 kernel so i can root it), i tried to flash the kernel via flashtool, it gave some type or error and my phone rebooted but after the sony logo it appeared an rectangle with an exclamation mark and turned off.
I've tried to flash via flashboot the previous kernel 587, and via flashtool but no sucess..
Pc companion doesnt recognize the phone cause the Arc turns on but turns off after getting to the triangle.
Is it bricked? :x
Thanks.
___________________________
I downloaded the recent Arc S rom (587) and flashed it via flashtool and it worked! No more triangles!
Sorry for opening the topic, hope it helps future users in the same situation.

[Q] Xperia Arc keeps booting up SONY XPERIA repeatedly -need urgent assistance

Xperia Arc
4.0.4/4.1.B.0.587
Bootloader Unlocked and Rooted
Guys,tried installing a custom Rom Omega on the 3rd.Nov,a couple of days ago.Followed every word the OP on how to install.Aroma popped up and made some choices and then rebooted into recovery.When phone switched back on only the SONY logo was there and it kept on repeating.Made some enquiries from members.Was advised to flash original firmware which I did.When the phone booted up,this time SONY XPERIA and kept on repeating.Been all over the place searching for a way to overcome this problem.
Came across an article on google:Recovering dead/bricked phone xperia arc -in that article there is mention of taking the generic global 4.1.B.0.587.zip file and extracting it to a .tft file and flashing it onto the device.This I am unsure of as I have never come across a .tft file.I've been unable to go into the main screen to make any changes to enable USB Debugging,Unknown Sources and MSC Mode if need be to flash again because when I tried doing it again the process aborted.Even tried to Relock bootloader so that SUS or PCCompanion would recognize the device
so that I can be able to get out of this mess I created.Unable to find a solution.Need urgent assistance.

You have to download the .ftf file (it's in the zip) on to your computer and flash it by using a tool called Flashtool.
Also flash stock kernel back or advanced stock kernel.

4 : please check thank !!!

bot @melvinhatred , @mahyjooon
seems like u have FLASHED wrong kernels, what are your Exact devices? E6xxx ?
tell me your devices , so that i can guide u better
when you downloaded latest FTF, why did u extract? there is not such need!
download full ftf file via FLASHTOOL ! / the last button on flashtool menu is Xperifirm , click it, select your DEVICE MODEL (accurately) from LEFTSIDE menu, then on the rightside, download LATEST rom as per your country (if country is not listed then Central USA / Europe , or MENA Arabic also) will do just fine.
after FLASHTOOL download and prepare your ftf file, connect your device in FLASH MODE and FLASH this rom (wipe data/kernel/system/setting/userdata ALL)
NOW --------------- since you have BRICKED/ bootloop fone try this
PRESS POWER+VOLUME up key for 5 seconds --- AS SOON AS FONE VIBRATE - RELEASE FINGERS INSTANTLY!!!!
if it restarts and goes in to boot loops then
PRESS POWER BUTTON + VOLUM UP KEY FOR 15 SECONDS --- THE FONE WILL VIBRATE 3 TIMES!!!!!!!!!!!!!!!!! WHILE ITS VIBRATING SECOND TIME, RELEASE YOUR FINGERS AT ONCE!!!
THE device will sleep.
now try connection your device for flashing in flash mode for FLASHTOOL
this trick / methods is tested by me for xperia z (older device),
tell me what happens with your z5 plzzzzzzzzzzzzzzzzzzzzzz

i have E6833, i was tring to root it via this guide
http://forum.xda-developers.com/z5-...ck-root-xperia-z5-premium-sony-stock-t3335974
but after installing supersu it faced softbrick and didn't boot so I tried to flash stock .253 tft file which i had downloaded from other sources , with flash tools but it stuck on modem.sin and i have to brought it to the shop to have it recover by box .its not the first time i'm facing the problem with flash tools , it always stock on one step for about an hour, the time before the last, i was trying to update it by flash tools and it stucked again.the xperia companion isn't working either -_- it says that it cant connect to network to find the update ! i checked the firewall and internet explorer internet options tab , but nothing worked for me ! my flash tools version is 0.9.22.0 build on 16-5-2016 . the last time i tried 0.9.18 version cause i saw somewhere that maybe the problem is related to new version but it didn't worked again, at the end what i think is that there should be zip flashing method from custom or stock recovery for flashing stock Roms too ! flash tools sucks in my case -_-

2. what were the sources u donwloaded the ftf file?
3. better to download ftf file via flashtool itself (last button is Xperifirm, click it, find SATSUKI dual E6833 and version of USA/ MENA ending .253) and flash it

Need Recovery Rom For Xperia XA1 G3116. IN SP Flash tool Image and scatter file

My Mobile of Xperia XA1 Died while trying to downgrade firmware via Xperia Flashtool.
it shows Red light only while usb connected or being charged. (Hard Bricked as i know).
Mobile is recognized as USB Serial Device in Device manager.
i Read somewhere that if i can get a SP Flash tool compatible Firmware Image and Scatter file, i can try to reflash.
i tried to find it over internet but no luck with Firmware or Rom and Scatter file.
While these many threads in XDA Community i hope that someone can make it for me if possible and i can try that.
Any Help or suggestion is welcome.
(Nearby Sony Service center says they don't do this mobile anymore and i will have to go to a city far far away for next center)
Phone is out of warranty. Bootloader was untempered (still locked i suppose) , not rooted , not customized, no custom recovery.
Phone's camera stopped working and even factory reset didn't helped so was trying to flash the factory stock rom. and it didn't go well.
Tried: Xperia Flash tool, Xperia Companion ( Can't boot to Fastboot via Vol down)
i Don't have any Box to proceed with.
Model: Sony Xperia XA1 G3116 (India)
