Xperia arc stuck in boot loop - Xperia Arc Q&A, Help & Troubleshooting

Hi, i recently upgraded my xperia arc lt15i to the new ics software, all went well and everything working fine so i decided to root the phone which i managed to do with no problems. Being the tinkerer that i am i decided to move some files from my phone memory to sd card. Bad idea! My phone locked up and is now stuck in boot loop. I tried to flash the ics firmware but cannot do it because i need to turn on usb debugging which obviously i can't do. Is there anyway i can resolve this? The annoying thing is that i can see the files i moved on my sd card when plugged into my laptop if only i could transfer them back to phone memory all would be good. Any help is much appreciated.
Thanks Phil

Use aroma file manager from the android dev forums. It'll let you move files in recovery.

Aroma File manager can be found in the Android themes and apps section (not in Arc themes and apps) i think so..
To boot into recovery press the volume down button while Sony Ericsson logo (name) is shown

Ok, so i've found the aroma file and copied it to sd card. Now I can't seem to get my phone into recovery mode. Also how will i know my phone is in recovery???

You'll need a kernel that has cwm to get into recovery...
So flash a new kernel on and then press volume down on boot screen to get into recovery. Though this means you'll have to unlock your boot loader

I tried flashing new software to my phone but it wouldn't have it because usb debugging can't be turned on, will i have the same problem trying to flash a kernal?
Cheers

How do i flash a kernal with cwm to my phone, do i need to have fastboot on my computer? I fear i am getting out of my depth! i need an idiots guide!!

Flashing a kernel doesn't deal with usb debugging and all.. First of all, tell me whether your bootloader is unlocked or not! Then I'll explain in steps!
Sent from my LT15i using XDA

Neither u need usb debugging to flash a new firmware or to upgrade the current rom..
for flashing purposes only fastboot or flashmode are required..
download the ics firmware ftf file and flash it via flashtool..

At Gire.prasad, I haven't unlocked the boot loader so i asume it is locked.
At now.i.feel. I tried flashing ics firmware again via flash tool but it wouldn't do it, it came up with an error saying it can't connect to my phone.
Thanks

Yes Yes Yes, my phone is back in action. I just flash ics firmware using flashtool again and it worked fine. i tried this the other day and it didn't work so something i downloaded from all of the posts must of helped.
Thankyou thankyou thankyou
It has been a learning curve and i have learnt my lesson. Not to dive in too deep too fast!!!
Thanks to you all again for your in put.

[HELP] computers arent recognizing the device after bootloader unlock

i have just unlocked the device bootloader and it works, but the wired thing is that i cant make the device appear on the computer from the usb connection.
what can i do?
More details wouldn't go a miss.
i cant understand why it happend, and i couldnt reach the sdcard without the phone (no SD available) so i used an old phone with the same connection as the arc and reached the sd card threw him to put the files for cm7 flashing.
another questions if anyone will know - what are the pros and the cons of CM7 vs SE stock rom?
Hi!
I haved the same issue. I think we deleted some system app.
I suggest to flash the stock ftf with flashtool first. And WIPE USER DATA.
After then, the CM7 boot.img and the rom once more. And WIPE USER DATA.
This way is solved the problem to me.
bukest
ps.: of course, you will lose all your data. but I only found this way to solved that problem.
damn it! huge problem!
i tried to flash the lt18i ftf file from the CM7 thread and i got stuck on the SE boot screen, boot loop.
so i tried to flash again the kernal and install the updated files from the sd and it makes the phone stuck on the free xperia project logo.
what to do?

Bro, you doing the same things like me, lol. DD
1. Flash lt18i ftf.
2. Flash Doomlord .42 (v13) kernel.
Now, you have .42 with root. If you like it, jump to 6.
If you don't like it:
3. Flash cm7 boot.img
4. Update CM7 from CWM
5. Update Gapps from CWM
Now you have CM7.1 (FXP45)
6. Enjoy.
i did 3-5 (im sure the first two are not necessary) and its still stuck on the free xperia project logo

Okay. The first 2 solved the problem for me. I'm still on .42(LT18i) with Doomlord v13 kernel. Try to take this to have a working phone first.
But if you found another way, don't hesitate to share the results.
Best regards,
bukest
yea i tried and its working.(no bootloop)
thank you
btw - feels alot more faster! i have to test it XD

[Q] Rooting confusion (LT18i, gb2.3.4, 4.0.2.A.0.62 )

Hi,
I am trying to root my phone. I have read many many guides on here but am still very confused...
I have successfuly unlocked the bootloader but I am unsure what to do next, every guide seems to be for different versions and the ones that are for the same version are too technical (I am new to the world of smartphones).
I have downloaded loads of files but I just dont know which ones I need and what to do with them...
can somebody please tell me which files I need, where do I put them and what I need to do (in plain English please).
My main reason for rooting is to remove the bloatware and get more performance/battery life for my device. I would also like to try out ICS (The update wasn't available in my country).
Thanks for any help and please dont say 'try searching', I have been reading for like 2 days now and just ended up getting more and more confused...
Thanks again.
A post from another thread...
Flash rootXperia.zip through CWM. That's it, you're rooted
Click to expand...
Click to collapse
Seems this is what I need to do, but how?
The easiest thing to do is find stock kernel with cwm installed and use that to flash the root.zip or you could install a custom rom?
Sent from my LT18i using xda app-developers app
So you want to root Gingerbread? Or do you want to update to ICS and then root it?
Either way, it doesn't matter. Since you already have an unlocked bootloader, it's a breeze.
Download a custom kernel with CWM and flash the superuser binary through it. If you want to root GB, make sure it's a GB compatible kernel and likewise with ICS as well.
If you want to update to ICS, have a look at the thread here. I suggest you grab the 4.0.4 Generic Global World .431fw. It's got the least bloatware and it's pretty snappy.
Update to the latest version of Flashtool. Get it here. The latest is v0.8.6.0. (Make sure that USB debugging and Unknown Sources are allowed beforehand).
Update to ICS.
Grab a custom kernel with CWM from the Development section. I use Jimbo77's ArcKnight kernel.
Get the latest superuser binary here. Place the zip file in the root of your SD card.
Hotboot the kernel using Flashtool. When the LED lights up blue, press the Back button. (If you think you're going to miss that instance, start spamming the Back button when it lights up).
There's an option to install a zip file. Browse to the superuser.zip on your SD card and flash it. That's it. When you reboot your phone, you automatically go back to the Stock kernel but you will have root access.
Cheers!
Thanks for your replies.
I figure I should stick with Gingerbread for the moment, at least til I know what I am doing...
I have a file called LT18i_4.0.2.A.0.62_Generic World UK.ftf. Is this the custom Kernel with CWM?
How do I flash it?
I have a file called rootXperia.zip, from what I understand, I need to put this onto the SD card, attach the phone in fastboot mode, open fastboot and click 'flash', is that right? Where do I put the ftf file?
Sorry for all the dumb questions, I'm quite clever really, just very new to this...
That file which you have is the fw. You need to put it in the firmware folder of Flashtool.
To flash the fw, you need to put it in flash mode i.e. holding the back button.
Get a custom kernel from the Development section. Try the appropriate DooMKernel for GB.
Use the latest superuser file I mentioned in the previous post.
For the kernel, put the phone in fastboot mode i.e. holding the menu button.

no dude LT18i_4.0.2.A.0.62_Generic World UK.ftf is a stock OS image file..it doesnt have custom kernel.. search in dev section..u will find one advanced stock kernel by doomlord if u want to stick to stock kernel.
u can flash ftf files using flashtools and u have to be in fastboot mode to flash custom kernel
Ok, So I have downloaded a file called ARC-advanced-Stock-v01-boot from DoomLord (I couldn't open the download for DoomKernel but he says its the same minus some features). This is in my firmwares folder
SuperUser-3.1.3-arm-signed is on my SD card.
Now I go into fastboot mode and open flashtools and click flash?
Im starting to think it might be easier and quicker to fly to India and have you do it for me....
go into fastboot mode..in flashtools click on "lightening" icon and select fastboot mode..then click on select to flash kernel..then browse and let it flash ..it will take only 1 second tats all then you are done..
Now my phone wont boot!
If I press power then it vibrates but nothing happens...
If I take the batt out then hold menu and plug in I can still get into fastboot mode, should I flash with ARCRecovery to fix it?
Only ftf files should be kept in the firmwares folder.
The kernel can be anywhere. Connect your phone in fastboot mode. (Switch off your phone, press and hold the menu button and then plug in the USB).
Press the lightning button on Flashtool and choose fastboot. Choose to hotboot a kernel and point to the kernel you downloaded. Then follow what I said about installing the zip through CWM.
Swyped from my SE Xperia arc (LT15i) using Tapatalk 2
Bricked?
So I followed all the instructions but now my phone wont switch on.
At first I was getting a boot screen that just said 'SONY', the key lights came on and I could get into the recovery menu but nothing else, it just kept rebooting.
I flashed another Kernel, thinking that somehow I had flashed the wrong one before and now I dont even get the SONY screen, just nothing. The screen backlight is on but there is no boot screen.
Any advice?
if u see sony logo then its not a kernel problem..most likely it is ROM problem...
do one thing...flash advanced stock kernel again properly. and flash a ROM called aconium 8.2...it is stock ROM with tweaks...
Mate, go grab another ftf.
This time, try ICS :fingers-crossed: LOL! Just follow the instructions I had given here.
When I select flashmode it does not show the ftf files on my computer, I also cannot drag and drop them into the flashtool window, am I misundersanding something?
drag and drop should work irrespective of whether phone is connected or not..if it doesnt allow DnD then there is some problem..
Install the drivers from the Flashtool folder again.
Swyped from my SE Xperia arc (LT15i) using Tapatalk 2
*sigh* I think I should give up, my phone is f*cked now.
Hopefully someone ina phone shop might be able to do something with it. If not then I guess Ill buy a new one and stick with having it unrooted.
Thanks for trying to help me guys, you have been very patient.
dont giveup dude..go through some tutorials and start again from scratch..
uninstall flashtools and reinstall and install drivers from here http://www.multiupload.com/0XZV1LXRVA
I just reinstalled and updated flashtools and installed all the drivers but it still wont let me drag and drop and still doesnt show ftf files in flashmode. I have restarted my computer and done everything I can think of.
Is there any possiblity that the damage to my phone is permanent (I assume that as I have only updated software then it should be reversable) and do you think that if I took it to an expert they would be able to fix it?

Hi Sam,
You can use CWM to format "system", and clear the cache.
Then re-flash the rom, and see if that allows you to boot up normally.
If this fails, then you can flash one of the stock roms on this thread to get your phone up and running again - http://forum.xda-developers.com/showthread.php?t=1653188
Once you are up and running, remember to make a CWM backup before trying something risky (and yes, Google apps can be considered risky )

OK, so now you need to use "flashtool" - you'll have to search for it on the forums if you don't know what to look for...
Then you can find the firmware for your phone on this thread - http://forum.xda-developers.com/showthread.php?p=22105604
When you use flashtool with a firmware like this it overwrites the entire operating system with one that definitely works - even if you have a locked boot-loader.
Once you have a working phone you can start with the whole root and custom rom thing again...
Good luck
the reason for your bootloop is wrong kernel i think... you may have tried to flash jellybean rom with ics kernel...try to change kernel if you wanna flash jb again

Hello, Hotfingers
I'm sorry to revive this old thread, but I seem to have the same problem - only I flashed back to my stock firmware using flashtool and it's STILL stuck on the Sony logo for a whole half hour with nothing new on the screen. Can anyone help me out here?
edit: never mind, I found out that I was flashing the kernel the whole time rather than the firmware. Thank you very much for the help!
Hotfingers please Help ME
the phone only shows the sony logo but does connect by fastboot.
i have attached the log. the flashtool wont go pass where it says device connected.
please help....
same problem here
To recover, put your phone into flashmode and then install stock firmware from a FTF file by using Flashtool.

[Q] [HELP][Xperia S]Struck with many problems on my Xperia S while flashing CM10

Hi All,
First of all, Thanks to XDA and FreeXperia project. You guys are doing great.
Problem Description:
Initially my phone had a Genuine ICS 4.04 from Sony Xperia [build 6.1.A.2.55]. I heard about CM10 and Jelly Bean 4.1.2 for Xperia S and I wanted to try it out.
So, at first, for unlocking the bootloader, I followed a few procedures suggested in XDA forums about Xperia S and Youtube videos on how to root it and so, I was able to unlock it successfully.
Next while flashing(This is where I made a mistake) , I downloaded FXP202-cm-10-20130110-UNOFFICIAL-anzu.zip from FreeXperia project site.
I pushed the FXP202-cm-10-20130110-UNOFFICIAL-anzu.zip to sdcard.
I flashed boot.img, but the flash didnt succeed.
Later I figured out that I had to download FXP202-cm-10-20130110-UNOFFICIAL-nozomi.zip. The LT26i was a.k.a "nozomi".
I flashed boot.img now again which is from FXP202-cm-10-20130110-UNOFFICIAL-nozomi.zip, then I could see the FreeXpria Logo and purple light on top. I pressed vol up to enter recovery mode.
But, now the zip image in sdcard is FXP202-cm-10-20130110-UNOFFICIAL-anzu.zip. So, I cannot flash that.
Is there anyway for me to copy the FXP202-cm-10-20130110-UNOFFICIAL-nozomi.zip file in my PC to a location in sdcard of phone so that I can point to it during the recovery mode or during fastboot mode, to take it and flash it ??
Is there anyway for me to completely redo the whole set of procedures, putting my phone to a sane state, fully working state with old 4.04 running on it ??
Later, adding to the list of risks, I tried the below command to flash all the contents in the FXP202-cm-10-20130110-UNOFFICIAL-nozomi.zip file after all the above procedures.
" fastboot flash system FXP202-cm-10-20130110-UNOFFICIAL-nozomi.zip "
I see that it succeeds in flashing too, but didnt boot up.
Help me to proceed now.

Xperia Arc Stuck in Loading

Hey guys! Today I rooted my device, installed CWM and installed a ROM onto my Arc device today. It all went fine but when I rebooted after the install the device seems to be stuck at the "Sony" logo. I cant seem to boot it into CWM (tried it couple of times). I'm new to this so does anyone know what the problem might be?
Thanks in advance
Did you unlock the bootloader? Flashed the right kernel? Explain a bit what did you flash and how.

I'm kinda new to this and I just did what the guide told me to do , which is the following:
For Locked Bootloaders: Root your phone using this tutorial, than install CWM using this app
Place ROM on SD-Card
Back up user apps and data. (Various apps available, search Google Play. This is a popular one)
Power off phone.
Boot to CWM (Keep pressing the Volume Down key after the Sony logo appears)
Wipe Data/Factory Reset
Mounts and Storage --> Format /System
Advanced > Wipe Battery Stats
Install zip from SD card > Choose Xperia Ultimate HD
Follow on screen instructions on AROMA.
After Complete Installation untick "reboot" and select reboot in CWM
Give the phone a good full charge, and enjoy your brand new phone!
Okay I suppose you flashed this rom and installed it with aroma installer. And you can't boot into recovery mode when logo appears (by pressing vol down button?)
Argh I had the same problem when using different rom with aroma installer and I couldn't boot in recovery mode. The main problem was not getting into cwm so I had to flash the stock rom (ftf file) back on arc using flashtool and I rooted the phone and unlocked BL again. Then I restored the previous backed up rom.
Is there any particular reason to have locked BL? You can do it with flashtool.
I don't know what the problem would be since I don't have enough experience with aroma installers, I just know the basics of flashing, installing and I can solve problems on my own arc when I f*** up something but I'm a bit confused here so you better wait for someone who has more brains than I do.

I just want to put my standard rom on there atm, can you link me to something that tells me how to do that?
Ok, so here's thread with stock, custom roms, kernels etc. here find the stock rom and choose version (lt15i or lt18i depends on which phone you have and where you're from) and download the ftf file.
Then go to this link where you'll get direct instructions on how to flash. It's really not that complicated. Just open flashtool, choose flashmode and browse for the ftf file, then flash it.
Good luck.
If you wish us to help you, at least tell which ROM you installed.
For a locked bootloader, flash the original TFT through Flashtool.
Root.
Install CWM.
Reflash ROM.
If your bootloader is unlocked, just flash a kernel with CWM included.
Mount your SD Card.
Put the ROM on it.
Flash.
Hope I helped you !
Cheers.
