"No OS Installed" - Fix May 25, 2015

rowland · May 25, 2015

rowland , May 25, 2015 :

Hi,

Before I start I want to give full credit to Max Lee or ZedoMax. You can find his youtube channel here (https://www.youtube.com/user/zedomax/)

So I'm sure some of you are very worried because your phone is n't booting up. This is most likely because you don't OS (operating system) installed. Boot into your recovery (power on button and up volume at the same time). Wait for the vibration and let go. You show now be in recovery. To make sure you have no OS installed push the reboot button and system. If at the top it says "no OS installed" then this guide will fix your issue.

Step 1: Boot in TWRP or CWR recovery (instructions above) and connect your OPO to your
computer.

Step 2: If you are Mac or Linux skip this step. If you are Windows you must download the ADB
drivers (unless you already have them). Follow these instructions here on how to install them: http://www.technobuzz.net/install-oneplus-one-usb-drivers-windows/
Drivers: http://downloadandroidrom.com/file/drivers/Android/usb_driver.zip

Step 3: Download the fast boot folder and unzip it. Make sure it is in your downloads folder!
http://downloadandroidrom.com/file/tools/fastboot.zip

Step 4: Install the ROM you would like to install (Oxygen, Cyanogen, etc...) on your computer.
Place the .zip of your ROM in the fast boot folder (in your downloads folder)

Step 5: Open a terminal or command prompt window and type:

For Windows:
cd downloads
cd fastboot
adb devices

For Mac:
cd Downloads
cd fastboot
chmod 755 *
./adb-mac devices

For Linux:
cd Downloads
cd fastboot
chmod 755 *
sudo ./adb-linux devices

You should see your Android device serial number along with “recovery”. If you see that, you are good to go.

Step 6: push your ROM to your android device. (Replace "filename" with ROM file)

For Windows:
adb push filename /sdcard/.

For Mac:
./adb-mac push filename /sdcard/.

For Linux:
sudo ./adb-linux push filename /sdcard/.

Step 7: In TWRP/CWR click install and find your ROM file. Then click reboot and system. Install
Super User if you want to root your device.

I have TWRP installed on my phone but when it type "adb devices" on command prompt it doesnt list my device. Any thoughts or do I use it as a paper weight now?

theincredible · Sep 15, 2016

theincredible , Sep 15, 2016 :

Its because your driver installation is not proper follow the guide in the first post of one plus one development to fix that.Also you can follow the steps for fastboot installation of cyanogen os fastboot images to fix your phone.

completely power off phone, then hold vol-down and plug in USB cable... this should boot you into fastboot, try and flash TWRP from there, although, if you dont have the required files on your device (or any way to get them onto it) you are not in a good situation.
something similar happened to me the other day, and this got me into fastboot where i could flash a system.img (or use HWOTA or whatever it is), though i had TWRP installed, but no OS.
