I've been using a TL2 for several weeks now without problems. Previously, I was able to reflash the firmware, install modules, and then download and run example applications on the phone. I wrote a few of my own applications, and they worked fine.

Usually, if there's no SIM in my phone, it will not start up, but instead request that I insert a SIM. Recently, I installed an application that seems to have broken the TL2. When I insert the TL2 w/ SIM and try, the phone does not request a SIM (seems to have detected it), but instead, it just hangs and never gets to the main menu.

When I tried to run the cemu application, it printed the SIM_ATR line and then hanged. I had two TL2s, so I tried using the other (without any of my own apps installed) to make sure there wasn't an error with the SIM. That seemed to work fine, so apparently the SIM was fine. I could run cemu and install new apps. I tried installing the one that had not worked on the first TL2, and cemu succeeded. Then I tried to insert that TL2 into my phone, and the hanging problem occurred. When I tried to reprogram that TL2 with cemu again, it hanged after the SIM_ATR line.

I tried to reflash using install_firmware and install_modules. Both of these scripts run without complaining (they never seem to complain anyways). But then cemu hangs. I once tried running install_firmware without install_modules, and cemu then said that sim.trb wasn't found (makes sense). So I know those scripts are doing something.

I tried reflashing one of the TL2s with btldr (tprog_kernel-3.1.1.bin). I ran in verbose mode, and everything seemed successful, but now any time I try to use cemu with it, it says "NO SIM". I can still re-run btldr with successful result reported.

I've had the cable on one TL2 break once, but I resoldered and checked the connections. Everything seems fine there. I just don't seem to have a way to check the TL2 memory to see if I overwrote anything important and irreplaceable.

Any advice about what steps I can take to completely reset the state of the TL2 and get applications on it again?

I've probed the ME-TL2 interface and collected data for what happens when the phone is powered on with the TL2 w/ SIM in it. There seems to be some kind of repeated power failure issue. I'm going to email the CSV file I collected.
