[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.

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,

yea i tried and its working.(no bootloop)
thank you
btw - feels alot more faster! i have to test it XD

Xperia arc stuck in boot loop

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.

Cheers

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
Sent from my LT15i using XDA

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.

[Q] Unable to boot Xperia Arc after flashing (Also not able to boot to CWM recovery)

I had rooted and loaded CM9 on my Xperia Arc 2 months before.
Today I tried to install one of the unofficial CM10 available in the community.
But it didn't work( stuck at the loading/splash screen).
Then I tried to re-install the CM9 but failed.
Then I flashed with LT15i_4.1.B.0.431_kernel.ftf rolleyes:)
After that it is stuck at loading with SONY logo.
Previously it was "FreeXperia" logo and I was able to boot to CWM screen. But Now I am not able to do that either.
Please guide me through on what to do now. I just want to get any ROM installed and the phone running.

If you can't get it to work (stuck on Sony logo), then flash this in flash tool.

Thanks for your quick reply.
I'll try this one..
Currently I am trying to restore with Sony Update Sftware

Good luck and let us know how it goes.
Btw.. a tip for later

You tried to install back just the kernel, not the whole ROM. That caused the problem, certain ROMs and kernels do not work together.
You need to install full ROM, so either with a .ftf file or Sony Update Service.

[Q] LT15i bricked: how to get into CWM??

Good morning,
Yesterday, I tried to unlock and root my friend's Xperia Arc (LT15i). Although it was running FW .62, I did manage to unlock the bootloader and root the phone. I installed CWM, emptied the phone (I thought) and installed the Xperia Ultimate HD ROM.
Unfortunately, I think I forgot a detail. I wiped data/factory reset, cache and Dalvik, but after the installation of the ROM completed succesfully, rebooting the phone keeps it hanging at the Sony Ericsson logo. It seems to be hanging right at that moment, because the problem is that when I then press the Vol.Down button, I'm not getting back into CWM.
I tried to use the "Unbrick" option to flash an original .ftf file via Flashtool, but then I get the "Error in processHeader: 1 Incorrect function".
Can anybody give me a clue on how to:
a) get into CWM
or
b) restore the phone so I can try again
Thanks a lot in advance!
PS: is there a way to get in the bootloader and go to CWM from there? It all seems to be so much more difficult then on my own Nexus S

FW .62 is gingerbread ROM and UHD is ICS ROM.I think you forgot to install ICS kernel. Use the suggested lupus kernel for UHD or any other ICS kernel in Fastboot mod or using flash tool then you can boot into ICS.

Oh crap, I didn't even think about that I figured it would be implemented in the ROM. Thanks a lot, I'll try that right away when I get home! :good:

Flashing ROM doesn't flash kernel.You need to flash kernel if you are flashing different version of ROM like Gb,ICS,JB. Flash kernel,then go to CWM and flash ROM zip.

Ok, I will try it. Thanks

Another question: After installing CWM there is no bootloop but it shows only sony logo ,then the phone goes down and can be booted again when battery is reinserted. Is it normal? Can I still flash it without any problems?

The same problem after I installed cwm. After that everything was back to normal.

Thanks everyone, now I am relieved a little.

I cannot flash it. When I connect the phone in flash mode after the flashtool has prepared the files an error comes that processing of loader.sin finished with errors and flashing is aborted. Please help me!!

Can flashing a custom rom using recovery help me beacause the flashtool won't work using any of the ftf files?
