My Orange San Diego has some hardware problem with charging. Orange has asked me to update to the latest version before they are prepared to investigate this issue, I assume they mean the 37MB OTA update to 4.0.5.
Question 1: my ROM is 4.0.4 and rooted - so how I can unroot it? I assume the AIO tool will do that.
Question 2: if I apply the OTA update, can I still root it later? Do I have to downgrade - can I downgrade?
I have tried to find this out, but the documentation for the OTA is rather hard to follow. Any help is very much appreciated.
