Vodafone VODI[SWB]: Is this the trend reversal?

Vodafone has been in a downtrend till the end of November. However, from the beginning of December, the RSI 14 has been pretty much rangebound between 37 and 50, even though the downtrend has not been broken. Rejecting the lows has formed a hammer on fridays trading session and a strong support remains at 1.65.
1h chart shows a daytrading / swingtrading opportunity while the 1d chart could indicate a longer-term trend reversal (maybe weeks to months). Regardlessly, the downtrend is still not broken so exercise caution.
