[Q] Bootloop Arc S (LT18i) - Xperia Arc Q&A, Help & Troubleshooting

Hey guys so I'm in boot loop. Yes I know there are many guides all over saying how to fix it but I have tried many of them and they didnt work.
What happens is I start the phone, it shows the boot image and then restarts after a time.
I can boot into the Recovery mode by spamming the back button when the Logo comes. And can install zip files from the SD card.
I also have tried flashtool to restore it to stock but when i try flashing it detects my device "Device connected in flash mode" but when i try toflash it, it gives an error "Error flashing. Aborted".
Any help?

Have you backup ?
Did you install a custom kernel ?

No i didnt back up and I bought it second hand. It has DoomKernel

Flash a ics kernel and report back. It might be a wrong kernel/rom combination
Post by NASA Computer from the 1960s

Just try flashing a new kernel, depending on the Android ROM you are using.

I'm unable to flasha new kernel. When i connect the phone to the coputer in fastboot mode it doesnt recognize it. I'm trying to flash the ArcKnight one.
When i plug it in to the computer in fastboot mode (blue light), the computer says USB device not recognized

Did you install the drivers for the device properly? Like, the flash-tool-drivers? http://forum.xda-developers.com/showthread.php?t=1034087

Mephistho is right. But if you want to make sure and be safe with it, use sony flashtool to install official fw then you can start your way up from there.

[Q] HELP Please! USB connection on my Arc has gone...

:crying:
Hi There!
I flash this kernel under my arconium rom v2.4:
http://forum.xda-developers.com/showthread.php?t=1838916
after I update my rom to Ice Bean v4.2n:
http://forum.xda-developers.com/showthread.php?t=1786871
This combination don't like me, but the USB has worked. So I flash back the arconium 2.4 from cwm backup and I flash back the DooMKernel v4 with fastboot. Clear Cache + Dalvik then boot flawlessly, but from this time the Arc don't have USB data connection, like MTP, STP, fastboot and other.
USB usable only charge.
I try many PCs, cables and drivers and I update other roms, don't help...
I can use recovery and I can flash update zip, but no fastboot.
Please help what can I do in this case!
If this is kernel related and no working fastboot, what other method help me to flash kernel.
May I use OTA?
Thank you!
Its an kernel problem, so just flash another kernel you'll like (make sure it has MTP Storage, STP working)
Need to flash an other kernel but I can't!
Hi,
I try, but I haven't fastboot mode. If I push menu button and plug in the USB cable, the blue led is lit and no answer any fastboot command.
Same reason I cant use Flashtool . Also don't work as card reader either MTP or STP mode.
Need to flash an other kernel but I can't!
Regards,
Z
Can u boot into flash mode ? If u can then flash a Sony firmware...

[Q] need help with a bricked phone

what shoul i do now?
Use flashtool to flash stock ftf of your model.
Sent from my R800x
i di that but it said that you sould install drivers and i installed them but it always gives that error
when you start flashtool dont have your phone connected. just click the lightning symbol then click flash mode. select the ftf file you need to flash. then when it asks for you to connect it in flash mode turn off phone then hold the back button and connect to usb. it should go thru.
thanks
thanx for youre help i have my phone back:laugh:
now booting my phone
Not a problem man.

[Q] Can't get in CWM mode.

Hello Guys, i have a huge problem.
I flashed kernel for Mango not for anzu. I mistakened the boot.img file and now my phone is stuck on boot screen.
Tried everything in forums and nothing works for me!
MY phone is rooted (or was, don't know what's now with the phone)
Was bootloader unlocked.
Everything was just fine, but wanted to get another Rom installed and did [Rom][WIP][JB4.2.2][Arc/S/Pro] Unofficial CM10.1 build 20130326, but installed the wrong boot.img
PC doesn't recognize my phone.
Can't get in CWM mode (
* My computer doesn't recognize the phone in fastboot mode (Entering by powering up and after pink led flash volume up)
In overall :
I got stuck black screen while booting, i guess 2nd boot screen
I get no logos, just black screen.
When adding USB and connecting to PC it shows just Green Led (it's fully charged)
Entering the Fastboot mode or CWM recovery mode (By powering up and after pink led flashes pushing volume up - it gives just a black screen and blue led (fastboot mode, i guess)
What could be the problem?
I've searched for answer about 2 days now, but no progress.
I'm desperate guys, HELP!

I don't know how to flash in flashmode.
I know that with Flashtools in flashmode I can flash Frameworks i guess (.ftf files).
If there is another way to flash with flashmode, then please enlighten me
I saw that there is Roms in zip and in .ftf files.
I want to have a ROM with .zip, but i'll try with .ftf firstly!
THE ROM I TRIED : http://forum.xda-developers.com/showthread.php?t=2147958
Tried my way, but no changes.
I NEED HELP!
Found a version of what could I do, but is there a posibility that I could make .ftf file from ZIP?http://forum.xda-developers.com/showthread.php?t=1849867

Click the first link in my sig, read, watch, learn, repair, done.
stock rom is FTF file. Flash them with flashtool. When you return your phone to complete stock and start over you flash a ftf file. And no you cannot turn a zip into a ftf

I've looked in your post, but didn't seem to understand what I need to get over my problem, please just direct me to right paragraph.
There is too many paragraphs!
How can I Change my Kernel, if I can't get in fastboot mode and in Recovery mode.
Only way I see is by flashmode option in Flashtools software.
BIG THANKS, i clicked THANK YOU!

[Q] Xperia S turned into Xperia SL?! Can't use Fastboot

hey guys
2 days ago i flashed this rom:
http://forum.xda-developers.com/showthread.php?t=2263625
after flash my Phone constantly restarts and i can't make Phone calls. By that i mean: i can pick up the calls but the other side can't hear me and i can't hear anything too. I even can't hear the voicemail.
So i decided to wipe dalvik cache and factory reset via CWM. I realized that CWM didn't work. i just can't get into recovery.
When i came home i tried to connect my Phone to my laptop but that didn't work neither. i can not acces my Phone using USB.
my laptop tried to install drivers but that didn't work. so what i see is that my laptop cannot recognize my Phone, pc companion could neither.
i've read the ROM thread again and i saw that there are to versions: UB & LB. i installed the UB on my xperia S and now model name says LT26ii.
And after that i saw one more thing: before flashing this ROM i had to flash the kernel first. i was so stupid because i didn't read everyhting.
and then i tried to flash this kernel via fastboot but i cannot get into fastboot. when i hold VOLUME UP and plug usb cable, i see the blue led, when i pull off the led goes out and my Phone restarts.
i don't know what to do
can anyone please help?? :crying:
thanks in advance!
try this
So im asuming that your Xperia S didnt flash properly , i suggest you re-install your FW
Method 1
Use flashtool to flash a STOCK FTF (do not forget to wipe Everything) (FTF can be found on XDA file server(Google it)
method 2
use a revovery to RE-install your STOCK ROM (if you dont have one there is plenty on XDA)
method 3
if all methods above dont work then try sending your xperia s for repairs or find your local super nerd

if u can, plz download the trinity ultimate kernel first and flash it
and kernel is usually not flashed with fastboot, but flash with recovery
cant get into CWM?? hmm, is it possible for u to install it again??
maybe u need to try another computer if u experience the adb error (yeah, my pc has that error sometimes)

I had the same problem once, and I had to install Xperia Arc's fastboot drivers so my phone would stay on fastboot.
Here are the ones I used, you have to manually install them.
you've chosec the wrong options in aroma
it's so simple
just reflash the rom and make sure this time you don't choose xperia sl

Go to Control Panel > System > Device Manager
When you connect the phone through fastboot, something should appear, right click > properties > update driver > search driver software on computer.
Well, this is the path por Windows 7...

remove batery after 10 seconds place it. now open flashtool and select correct firmware then flash. it shows preparing device. after 1 min it says to "connect phone in flash mode"
now only you have to connect your phone to pc it's important for bootloop devices.
press and hold volume down + connect usb
phone led turns into green

well make sure you install drivers for fast boot else it wont work
drivers are in flash tool folder C:\Flashtool\drivers in my case its here if you have used default settings look and install and select fastboot from list when installing
Download any ROM (Best is Cyongen or LiquidSmoooth)
Download a rom and boot your phone into fastboot mode and install .zip file.THAT'S IT :fingers-crossed::fingers-crossed:.Hit thanks button if I helped you
Bro if you have C2004 means I am ready to give my nandroid backup you can easily restore with Cwm no worries about flash mode other model means pls specify model no I will try...
