"Fatal exception die" after installing an update - HELP!!!
-
@Amarurtuuq MSM Download tool is the tool (Windows only) used to flash a stock Android ROM onto this device. If the RAM chip has gone then this isn't worth doing as it can be finicky to get this device into EDL mode (Emergency Download mode) and it will unlikely not work.
To boot into recovery mode, where you can wipe cache, power off the device and hold volume down and power, when the device boots, release the power button, but hold the volume down button until it reaches recovery. If it won't reach recovery, leave it powered off on charge overnight and try again. If that fails it is battery or motherboard.

I can't boot in recovery mode (in fact, I can't even switch off the phone, I am in a closed loop between the 2 screens). -
@Amarurtuuq OK hold the Volume up, Volume down and power together for about 40 seconds, that should turn the device off.
Just for your info, I had the same issue on one of my N100's. Charging it to 100% resolved the issue (for now, it is still working).
-
@MrT10001 Thanks for this information;
I will try to charge it (but I have some doubts, because there was a strange message after the Ubuntu update, but I didn't note it down, so I can't remember what the message was) -
@idonthatevests
I finally reached the fastboot mode.
I used the ubports-installer and wanted to reinstall Ubuntu Touch, but to my surprise, the installer saide that the device is not supported for UT.
How is it possible whereas Ubuntu Touch was installed on this phone before it crashed ?
I am so confused now...

-
@Amarurtuuq that's normal if you are installing from fastboot. Select your device from the drop down menu.
-
What do you mean by "drop down menu" ?
English is not my mother tongue, so I ave some trouble to understand
-
-
@MrT10001 Ah ok, thank you !
However, when I use this menu, the installer says that the OnePlus N100 must be "billie2" and mine seems to be called "bengal" (I don't know why).
I think I will stop for this evening.... I try since 3 hours, I need a pause... and I will let the phone charging. -
@Amarurtuuq Bengal is correct, it is the code name of the SoC (System on Chip) for this device, Billie2

@MrT10001 Thank you.
So I am less anxious. We'll see tomorrow what happens
