My Xperia Arc seems unrootable?! Please help me!
I may need your help!
I've got a Sony Ericsson Xperia Arc (Lt15i) with Android 2.3.4 on it. (Stock ROM)
When I got my Arc, I rootet it with the Doomloard tool... it worked without errors..
Then I had to send my mobilephone to the repair center because of a crack in the housing ... unfortunately they reset my Arc to stocksettings, like they ever did.
Then I tried to root it again, but it was not possible to root it one more time.
I installed flashtool 0.8.0.0 to flash the stockkernel once again, but rooting still doesn't work.While the rootingprocess there were errors like .. *failed to copy..* whatever..
When I watch the files on the intern phonestorage through Astro filemanager.. I'm able to see two folders which seem not to be removed through flashing or resetting to default settings etc. *root* and *sbin*
is it posssible that this two folders are the reasons why i can't root anymore?
If it's so, how can they be removed?
But may it be possible that I can only root the LT15i_4.0.2.A.0.42 ROM and not the later versions like .62 or .69?
I'm not able to find a working LT15i_4.0.2.A.0.42 Stock ROM in the internet.. all the ones I downloaded didn't work.. flashtool said flashing failed..
Could anyone post a link to me with a working .42 Stockkernel?
Or could anyone help me to root my mobile once again..
Nice greetings from Germany,
PS: I'm not very good on this area and my English is not the best, so it would be nice if you'll try to explain it very simple..
