Nova Air Recovery Image
I have a rooted Nova Air and I want to update the system, but my recovery seems to be broken and the recovery image is not included in the update package.
Can someone with rooted Nova Air help extract recovery image for me? thanks Step:

Hi.
You can use my custom recovery for NovaAir that I made a while ago. https://www.mobileread.com/forums/sh...84&postcount=6 It will boot to a white screen. You will have rooted ADB available. If you want the normal recovery screen, just: Code:
C:\>adb shell # start recovery |

Mmm, can you get to recovery just by:
Code:
adb reboot recovery I'll post it if you can't get to recovery. |

Seems maybe I can still get to the fastboot mode, just don't know how to do it. Also my device now can't boot to system too. Console log: Code:

Yes, the white screen is what you get.
Is something detectable over USB? When you plug it in does it go "bong"? Have you loaded ADB drivers? Do you see something in Device Manager (devmgmt.msc)? |

Hmm, maybe this one is bad and I never got it working.
What with Nova/Note/Air/2 I get this stuff confused. Also, I don't have one. And I Frankinsteined this out of a Poke3 recovery. Sorry. You should be able to get out of this by doing a long power press and then when it reacts press the power button five times. |

Try to use it to get to the fastboot mode but still no luck. Guess I have to take it to the service center. Code:
PS C:\Downloads> .\edl.exe /l Found EDL 900e Resetting Sahara Received unexpected 0x04 command PS C:\Downloads> .\edl.exe /zf Found EDL 900e Requesting reset to fastboot... No response PS C:\Downloads> |

You have 900e which is the less capable cousin of 9008.
Also, the /zf works only if you loaded a Firehose loader (which exists for your model). And /zf only works on some models. If you got 9008 we could fix it going to recovery. The 5 x power doesn't get you anywhere? If you have a spare USB cable to sacrifice you can try to make an "EDL cable". It doesn't work on my Poke3 but does on my Poke5. On both of these I also have found the test points and added a magnetic switch. Last edited by Renate; 09-15-2023 at 07:58 AM. |

Get a USB 2.0 Type C to Type A cable (this is Type C, isn't it?).
Get a cable where the Type A (the desktop side) is not blue inside. Pick a spot in the middle and nibble away the jacket for a few inches. Push aside everything but the black and the green wires. Nibble away the insulation on a section of the black and green. https://wiki.bananahackers.net/devel.../diy-edl-cable |

Even while bootlooping, it is more difficult but not impossible... you just need to observe an obvious point in the cycle to alter your timing against. If I had to do this trick today, I expect I would not do it correctly in under 5 attempts. Since you are not boot looping, you have a bit of control over when the reboot happens. Hold down power for X amount of time, release and do the 5 presses within 2 seconds. Change X until you find the right timing. |
