For a year, Elva rested as record companies fought over her next contract. It ended up becoming a battle between Warner Music Taiwan and Sony BMG, with Warner Music winning the battle in the end. Elva signed into Warner Music on March 23rd, 2005, making her Warner Taiwan's "fifth diva" (after Sammi Cheng, A-Mei Chang, Na Ying, and Stefanie Sun). Fans were overjoyed at this, and waited for the coming of a new album, which Warner had promised would be released in June 2005.
However, Warner Music Taiwan faced some serious issues during this time, including executives resigning and a change of staff members. Many other Warner artists (including Stefanie Sun, Machi, A-Mei, and F.I.R.) were affected and did not see much promotion. However, none faced as much trouble as Elva, whose album was delayed until September, then October, then November, December, until Warner announced that the album would be delayed indefinitely. This angered the fans, who had been waiting patiently. Their protests spammed the forums of Warner Music Taiwan, causing the entire website to be out of service for a week.
In February 2006, however, a Warner representative promised in an interview that the album would be released around late March/early April. It was only a few weeks later that magazine articles reported another change of staff members and the possibilities of the album being delayed into late April/early May.
In June 2006, she released a new single, entitled "The World I Want" [我要的世界].
In October 2006, the delayed album still had not been released, although Elva announced that it would be released in December. At that time she was in Los Angeles working on dance choreography. In addition, she released another new promotion single entitled "Elva Is Back", a fast catchy song featuring electro beats and raps.
Elva and Warner Music announced in November that her newest album would be released on 22 December. The album is entitled , signifying the number of days Elva had been absent from the Mandopop scene.
She released the music video for her single called "Confession" in mid-2007. Her second single is called "L.o.V.E". Her third single is called "Not Far Away". Her fourth single is called "The Ambassador. Her fifth single is called "Honey Honey Honey". Her sixth single is called "My Boyfriend".
Elva's first album back with EMI,三面夏娃, was originally set to be released in late May 2008. But due to the delay in production and of China's approval due to the Olympic Games , the album was pushed back and released on 13 June 2008.
She has had film roles in two movies: Infernal Affairs (2002) and The Butterfly Lovers (2004). She is longer participating in Fresh Tomato For Sauce (Announced 2007). However, she is currently in talks to play a role in the TV series Less Than Zero, a retake on Bret Easton Ellis' famous novel that will be set in Taipei.
And by joining EMI Virgin Records, the EMI's Gold Label Records which is seen as a inter-industrial agency is starting to find scripts and tailor-made contexts for Elva as she is planned to have more participations in movies under EMI as this is one of the strategic plans of EMI changes in Asia.
The first cross-media work is the co-partnership with Puma which Elva would become the spokesperson of Puma and Puma would buy media place including TVCs, print ads, billboards for the label and Elva's album. Puma would also sponsor Elva's music video "I'll Be There".
