[Q] Noob Question

---

I use the HTC automatically upgraded my phone to upgrade to 4.0.3, but my company's software only in the operation of the 2.3.6 version, would like to ask whether there are ways to drop back to the 2.3.6 version it?

I think you have to root it and delock the bootloader after that you have to install the RUU for your device and then relock the bootloader but I dont think your company will allow this becouse you lose warranty by doing this. You will only get it back if you relock the bootloader and erase the Root.

Theres no way to go back from official ICS to gingerbread untill we can S-Off and flash the old hboot back.

If you are not unlocked and the HTC software upgrade went through, you should contact your system admin and let them know what happened. Perhaps it is time for them to update their system? After all, if you root your phone, you will lose your warranty.
