[XDA Assist] Tidschimon:
Hey guys,

I spent all day to find a solution but I failed.

To start off, I've got a Sony Xperia L (taoshan), which I flashed with CyanogenMod using Clockworkmod.

Lately I updatet it to CyanogenMod 12 and slowly but steadily I got pissed because the CyanogenMod Recovery which was automatically installed with CM12 couldn't update to the next version, so I always had to manually flash the "old" boot.img of the cm11 in order to get a working recovery and then flash the new Version of CM12 which again blew out Clockworkmod.

Because I was annoyed of this I tried to install TWRP hoping it would solve that. Of course it didn't went as smooth as in any tutorial which would have been installing the app from the Playstore running it and done, but I had to flash it in the end.

So now TWRP "works". But it couldn't install the latest CM (a couple of hours have already passed, so I don't remember what the error message said or wheter there was a message at all)

Somewhen I did a full wipe to solve something but obviously it didn't work.

At some point I gave up trying to install the latest version and I started trying the Version I had running before. Luckily I still got the .zip of that very Version I flashed a couple of days ago using CWM, which means this .zip does definitly work!

But the sideload of TWRP does not work. The command promt says:"device not found" , while my Xperia L says waiting for input.

So I extracted my Micro Sd, plugged it into my PC copied the "Old" boot.img, that had CWM PLUS the .zip I intend to install and a .zip file with gapps I knew I had to install after the CM12.

After the transfer I repluged the micro sd back into my device and tried to install the CM12 ... .zip directly from the sdCard.

Well for a few seconds it looked like an installation process but then my phone directly rebootet TWRP without installing anything.

Then I tried moving the .zip onto the internal storage and install it from there.

There it says: "Error executing updater binary in zip..."

At that point I had enough of TWRP and tried to go back to my old method... Means

- turning the phone off

- extracting the boot.img from cm-11-20140827-NIGHTLY-taoshan

- setting my phone into fastboot by pressing volume up and connecting it

- open a commandprompt at the folder where fastboot.exe lies

- use fastboot flash boot "path to boot.img" to flash CWM onto my device

- use fastboot reboot and then volume up at the purple light to go to recovery, which should be by then CWM

And I saw a nice blue logo of Team Win Recovery Project and I wanted to cry...

So in Summary I searched a lot of Sites for a solution but didn't find a single one to solve one of my Problems...

For the lazy ones:

- I cannot use Sideload because the commandpromt doesn't recognize my phone... however it did when using CWM

- I cannot install it from my SDCard, because it reboots without doing anything

- I cannot install it from the internal storage because "Error executing updater binary in zip

- I cannot use CWM because if I flash the boot.img that brings about CWM nothing happens and I still have TWRP

Well I am at the end of my knowledge and I truly hope one the answers I get here work out.
