adb shell from recovery

Is it possible to obtain adb shell in recovery for DHD ?
I am trying to chmod /data/data/ to fix an error I made.

adb command as a single line? (with Ubuntu touch on Nexus 4)

How can I call adb command as a single line from cmd.exe?
Here is what I am executing when I run it regularly.
Code:
adb shell
ubuntu_chroot shell
cd /home/phablet/test
nohup ./test2.sh
I am able to run this:
Code:
adb shell "ubuntu_chroot shell"
Can I make all that I am trying to do (start execution of test2.sh script from ubuntu_chroot shell) with one single command?

[Q] D802 - Can not acces download mode

Hi, I need to downgrade to 4.2.2 but I can not acces download mode. It just says "download mode" and nothing else happens so I cant flash the .kdz file. I can boot recovery (TWRP). I cant find a working solution anywhere.
Thanks

Turn off the device, press volume up, plug in the cable at the same time, it will enter download mode.

I tried it many times. It wont. As I said, it just says "download mode" but it wont continue to the "firmware update" part..

What is your current firmware version?4.4.2 ?

Same thing here buddy

Yes. I had 4.2.2 but I tried ported kitkat. Then I flashed the old recovery, tried to restore the backup and nothing is working. So I need to unroot it but I cannot
get to that mode. What a mystery.

Here you need to do is write in detail. I've solved this issue by examining. Your solution is here.LG has closed since way back.

I've given subject solves your problem.

Im not sure if I understand. I was already aware of that guide. Thats why I need to boot "download mode" which I cant. I cant find there the solution. I also cant boot the system.

I just tried to connect flash disk via OTG and the phone does not see it in recovery. In other phone it works. So another way is out. I either need to get the download mode working or push .zip into the phone but I have no idea how since the OTG is not working.
