Problem with LineageOS 15.1 & TWRP install

[possla]

So, i have dusted off my old Z2 tablet, and wanted to update it to LineageOS 15.1. iam following the guide on Cyoanomods site. (Cant link, since i am a new member)

I have "rooted" it with sonys own guide. No problem there.
I have installed the ADB and fastboot on my pc. Can connect to it no problem.

Boot to bootloader via ADB no problem. Then i try to flash TWRP to recovery , it says OKAY to both sending and writing.
But the device just boots as normal, no matter if i use the reboot recovery command or by using the devices buttons. Just a standard recovery seems to happen.
The only strange thing i can think of is that the flash goes fairly fast, both tasks finishes in 1.6 seconds. Dont know if that is normal.
Tried to search around almost all day, but nothing gets any clearer. Found something that TRWP may not even work on the xperia units since it uses some other kind of boot partition.

Any ideas?

hi possla,
I have also just brought my Z2 tablet out of the sink and now I want to flash it with LineageOS 15.1. First, a question, do you have a current link to LOS15.1 for me?
Apart from that, I still remembered my fights with the tablet a few years ago, I flashed TWRP for backups, but when I flashed a new system it did not work with TWRP, so I have the CWM recovery 6.0.4.6 (Touch) on that Flashed tablet, so it worked fine, just try it.
If you had a LOS15.1 link for me it would be great, thanks in advance!

Greeting Torsten

Same problem for the past 2 years

Shut the device down. Switch it on. Wait until the led turns green. Now hit a volume button several times

Hi, i don't know if other thread's members encounter the same problem, but for me there is no light during boot form the device. Maybe it's only on this device but i can't get the solid green light during ADB mode. In this case i'm unable to enter Recovery Mode too after flash several times ...
