Not exactly what I said.
There is a chance, though more harm than good may come of it (especially if custom ROMs is/are tried)
For those interested, u can follow the Dell Official Update Process as listed below, and for more info, encourage to read through the entire thing:

Introduction
The OTA process for Dell devices is slightly different from normal OTA updates such as on Nexus devices.
On a Nexus or similar device with an update available the device downloads the latest update zip that contains the pieces required to update it to the lastest available version. On a Dell Android device it downloads an update pkg that is an update zip but in encrypted form.
Also on Dell devices, the roms are differentated by region, the decrypted update pkg will check to see that the current recovery region matches the update itself. So that you cannot install an update from a different region without reflashing your stock recovery.
A*fota mismatch*occurs when the recovery is from a different region then the update pkg, commonly caused by the user downloading the update manually. An example is trying to run a 00 region update (which would be a retail update) on a 31 region recovery device (which would be an At&t device)

(Assuming the device has a stock recovery installed)
