Raf'ul Yadein has not been abrogated, if anything the hadeeth of Abdullah Ibn masood that the hanafi's use to justify that Raf'ul Yadein isn't the act of the Prophet (saaws) is a da'eef hadeeth in many of the hadeeth books. Imam Ahmed Ibn Hambal (r) said this hadeeth is munkar (rejected). The hadeeth scholars who rejected this hadeeth are Abdullah Ibn Mubarak, Tirmidhi, Ibn Al-Jawzee, Ibn Hajar, Shawkani, Abu Hazim ar-Razi, Daraqutni, Ibn Hibban, ABu Dawood, Shafi'i, Ibn Abdul bar in Tamheed all of them said that this hadeeth is da'eef (weak).
This saying of Abdullah ibn Masood is that he would raise his hands at the beginning of the prayer (i.e. at the first takbeer) and then after that he would not raise his hands again. As I said above, the traditionalists regarded this saying as da'eef.
The hadeeth for Raf'ul Yadein if I remember correctly is in most of the hadeeth books in particular Bukhari and Muslim and is a confirmed sunnah of the Prophet (saaw). Ibn 'Umar said in Al-Bukhari that this is the action of the Prophet. Around 17 Sahaba narrated the hadeeth of Raf'ul Yadein.
Allah knows best.
