[Q] help updating to .62 firmware

i already flashed .42 via flashtool then root with zergrush but iam not abble to update over the air it says "update failed"
i havent removed any apps
¿Any other way to get .62 rooted firmware without unlocking bootloader?

i prefer u to not use .62 firmware as rooting in this firmware is not possible man..!!

check your internet connection..make sure you update it through wifi

I think i will stay on .42
thanks for your answers =)

Root .42 & Update to .62
If u want to update OTA ........
a) Your Boot loader should not be unlocked (Default setting by Sony Ericsson)
b) Root your phone which is running on .42 firmware using the latest Flashtools v 0.6.8
Note :
i.First install Flash tool.
ii.Connect the phone in Flash Mode
iii.Flash it with 4.0.2.A.0.42
iv.Turn on the phone when flashing complete
v.Connect the phone with usb debbuging enabled.
vi.Open the Flashtool
vii.Then press the lock icon on flashtool.
viii.Phone will automatically reeboot after done
c) After rooting update your phone OTA
You can try using Wifi/3G/Edge
OTA Updating
Turn on data network and use the Update center app which is by default in your applist
If u have accidently removed it then i an uploading it to BOX for you to download

What's the output of dooms .bat? I'm guessing you have a locked bootloader?

0.62 fw wasn't rootable when i had it. Just flash back with flashtool or wotan to 0.42 fw root with doomlords pack. Update again and it is rooted.

You can only get root on .42 with doomlords easy root.
Re flash .42 with flashtools get root, if bootloader is locked then update over the air to .62 root will remain.
DO NOT UPDATE OVER THE AIR IF BOOTLOADER IS UNLOCKED YOU WILL BRICK THE PHONE.

Over air update fails, back to official rom?

My update to 4.1.b.0.431 over air fail on my Sony Xperia Arc S. Pc Companignon tells me I tampered with software. I did some rooting some time ago but actually thought I was on the official ROM again.
Is it possible to flash back to an official ROM and receive future updates over the air again? Or did ruined that path the first time i was flashing ?
Right now im on
android version 4.0.3
build number 4.1.A.0.562
Thanks

Use the flashtool to update. http://forum.xda-developers.com/showthread.php?t=1653188

Do you have unlocked bootloader? If yes, relock it.

Will Update OTA brick my Arc?

Hi everyone, I just flashed again the 4.1.B.0.431 .ftf after some problems with custom roms.
PC Companion and the phone itself notified me about the update to 4.1.B.0.587. If I remember correctly, updating through PC Companion/OTA will brick my device because I have an unlocked bootloader? Or should I update without any worries?
Thanks.

yes, your phone will be bricked, using flashtool is easier and safer!

With unlocked bootloader you will brick the device DO NOT UPDATE OVER THE AIR.
