I did a complete Wipe and installed the Image from this Thread. Everything ok BUT there is absolutely no way to enter any Recovery now. LED is red at Boot and pressing Volume down nothing happens now only System Boot.

Before i have installed TWRP with Rashr directly to FOTA under CM12.
Follow the instruction from posti #47 and you are good.

Thx. Test it later or tomorrow. Any chance to get a Kernel only with TWRP?

Like Desperanto for Z3?

Works perfect now after applying batch. Anyway this DualRecovery makes no sense to me. Looks like a Toy for Fanboys. :)
Glad you got it to work. The thing with dualrecovery is that it works with unlocked bootloaders but also with locked bootloaders because it isn´t part of kernel. About you question about TWRP only kernel...hmm, maybe.

My Z2T is one of the ones that is lollipop w/o recovery or system r/w. The OP suggests downgrading and re-rooting; my plan was to install dual recovery v2.8.3 (pc installer method), then fix using byeselinux, then flash this ROM from recovery. Will that work?

If you are rooted Lollipop with system r/w you can directly install Dualrecovery 2.8.7 with pc installer. If you are rooted but system read only you can use RICDefeat to get system write acces and then install Dualrecovery 2.8.7 again with pc installer. Download RICDefeat here http://forum.xda-developers.com/attachment.php?attachmentid=3218460&d=1426763783 It isn´t flashable but installed via pc by runing script. If you don´t have root you have to downgrade to get root first.

Started with a Z2T on .690, rooted but without r/w and no recovery. Ran byeselinux and ricdefeat and successfully got recovery, but no system r/w. I flashed this ROM, and 2.8.7 was installed OK and reboot to system is fine, but still no r/w. Ideas to get r/w?? Thanks!

kulvertti, thanks for your great work.
You made it so easy for us to upgrade to lollipop.
After I made a full backup, I just wiped system partition, dalvik cache and cache on my SGP512 and install this firmware.
I had no problems so far, all is working perfect for me and I can still use all of my installed apps without factory reset.
Please keep on doing this thread, when new firmwares arrive.

Thanks
