Geçebilirsiniz fakat twrp de efs, splash, modem, system bölümleri gibi bir bölüm olan boot.img içerisine entegre edilir.
Bunu aşağıdaki tissot twrp kurulum dosyası(twrp-installer.sh) içerisinde görebilirsiniz ayrıntılı olarak:

## end boot image patchingAyrıca android one telefonlarda A ve B partition bölümleri var ve kodlarda da gördüğünüz üzere her iki partition üzerinde boot.img dosyası yeniden düzenleniyor ve treble romlar için yapılan repartition işlemleri de stock rom yüklemeye engel oluyor.
Bütün bunlardan dolayı twrp üzerinden stock rom yüklemeyi önermiyorum arkadaşlar.
