Sorry about the story, but I felt it is nessesary to give as much info, so someone can help me with this. A couple of days back I was on XDA, looking to figure out a way to get Oreo on my V20 H910. Since ATT has an update with it, and it wont let me get it. I was surprised to find out that this ATT H910 is real pain in the you know what to root. XDA had a few articles on this model. One caught my eye called [ROOT] HOWTO: AT&T H910 up to v20g (FULLY TESTED). It mentions something about this model is no long rootable with dirtysanta and so on. Anyways I followed all the instructions (to the best of my understanding) and eventually installed a H915 Freedom Mobile version. After that it got very complicated and stopped, for a while and went back a few times. I had to stop with this one. I then remembered Max had a tutorial on this phone. It looked fairly less complicated. I followed his instructions to Step 20. At that point the phone was supposed to go into twrp, but it didn't. It went into a Kernel crash! LGE Crash handler: Kernel Crash!
If you want to get a ram dump, Please do the following action.
- Please connect USB.
- Get the ram dump image using QPST configuration.
If you want to reboot, Press the volume down and hold for a second.
There is a bunch of codes and stuff after that.
Last is: Jump to XBLRamdump Mode.
I’m not sure what that was on the phone. I don’t believe it is bricked. Hopefully someone with the right knowledge can help with this. What can be done to complete this and finish this installation?
