This weekend I'm going to open one of my two Tagus and search for that resistor. Once I've removed the original firmware I cannot turn them back because there is no way to restore original one (Casa del Libro haven't put an update yet).

What exactly are you planning to do with that resistor?

EDIT
and, btw, this is an advice given in the russian forum:

I do not Verrier that there is something fundamentally changed, probably a couple of resistors and capacitors may well have changed where necessary to stick a jumper or eliminate

The answer is to reduce the minimum level of illumination necessary to replace R240 is 49.9 ohms.
EDIT2
my guess is the guy ment 0.49 ohms

I think 0.49 Ohms is very little resistance... It is practically a short...

However I will see device internals and see what current value of R240...

Look at the board directly under the battery next to the biggest capacitor.
There were 2 options wiring board. In the first - from The sides of the screen, the second - on the back

Смотрите на плате прямо под аккумулятором, рядом с самым большим конденсатором. Было 2 варианта разводки платы. В первом - со строны экрана, во втором - с обратной
