Is there a website that i can find steps to downgrade upgrade so that I can unlock bootloader and root my arc LT15i.
Thanks
You can unlock the bootloader on any firmware... and just search your question up on xda or google
Thanks I thought someone wrote that you could not do that on .62 firmware but they maybe said that I cant root on .62.
Yeh you cant root on .62 so you have to downgrade to .42 and root on that and if you still want to retain the root and go to .62 you have to do an OTA update
Listen,u cant root firmware .62 directly. However,there is a loophole. First,u need to flash firmaware .42. Then, root firmware .42 using zergrush rooting method( there is a thread somewhere in development). After that, check ur update app in the phone and u will get firmware .62 OTA notification. Just download and install it. This is the way to get firmware .62 rooted.
*u must be on locked bootloader
*make sure u dont delete anything after rooting firmware .42
*if u dont get the firmware .62 notification, its not my fault

I presume I once was on .42 and I updated to .62 firmware...
Can anyone tell me what, if any, difference is there between the two.
I have read that some of you have found that the phone is laggy on .62 and went back to .42
Is it maybe too much for the original Arc being on .62
And also I have read once you unlock the bootloader and downgrade, if you want to upgrade again, you have to relock the bootloader?
Thanks for any info
check this out its an excellent thread..

and sorry for ask alot
Solved
1. Unlock the Bootloader
2. Install Doomlord Stock Kernel 1.6 ( Pre rooted)
3. Install .62 stock Kernel from .ftf file (Root remains from Doomlord Stock Plus Kernel 1.6 even after installing .62 Rom kernel agian)
4. Re-lock the bootloader with the help of Flashtool.
5. You have Stock ROM rooted and with locked bootloader.
....Worked like Charm for me on my Arc s (LT18i, .62 ROM)
thanks
so what is the differnt between .62 and .42
btw i root my .42
All the Rooting Exploits don't work on .62 ROM as of now......Hence either you need to follow the trick I have mentioned or else roll back to .42........However there is no significance difference between .62 and .42................I am waiting for Official ICS
There's a better memory management according to people here

i have an xperia arc which was rooted 2.3.4 build .42
I updated over PC to .62, lost root. Now I want to revert back to .42, how can I do that safely
I used flashtool to root previously, prefer to use that again. Can I flash .42 back with no problems
Thanks in advance.

yah no problem at all ,you can use flashtool and you can root again then update thru OTA update so your root will still remain .
After my update from .42 to .69 I lost root access.
Now 3 weeks later I can't work without root. So I decided to unlock the Bootloader on my R800i.
How I get then the root access? Is it already there when I unlock the BL?
Or is there anything to do then, to get root.
How can I update to ICS?
With SEUS or normaly with the phone? And is the BL then even unlocked and will I have root access?
And is there a german manual how to unlock the BL?
To unlock the bootloader go here.
For root the only way I know for firmware .62 and up is by flashing a pre-rooted kernel like Doomkernel.

To update to ICS you have to flash a ICS Kernel/ROM. I suggest you either CyanogenMod 9 or Sony Official Beta. To flash CyanogenMod download the package from the official thread, flash the boot.img with <<fastboot flash boot boot.img>> then enter in recovery and flash the .zip package that has to be on your SD card.
To flash Sony Beta follow instructions in the topic but instead of the original boot.img flash DoomLord Advanced Kernel to gain root access.
Hi,...my Play came with 2.3.4 .42 locked bootloader,...i upgraded to .62 then unlocked the bootloader and rooted. Now i am wondering if i can flash back to .42 or .62 without any problems,...or do i have to re-lock the bootloader,..HELP!
Just re-flash the firmware with flashtool. You can go to any firmware that's compatible with your phone's model
thanx dude m on it!!!

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.
