He says it is relevant to all NVFS devices, not just E2; E2 is just the device which hits it most often. So in my opinion until it is fixed all-together, people with NVFS should not use this hack. @Lukas: try to contact Dmitry, maybe he will share with you how to fix this dangerous bug.

In retrospect, I should have thought a bit before posting... I have been helping Lukas fix the loop bug i mentioned and hopefully it will work soon enough. But until then I recommend all users keep your hands off of it... John Dale,

I hope you will be able to got your device replaced and that you can forgive me. You really should only use UDMH in the future since it is really more stable!! I´ll add a really big red warning on my site as soon as possible saying Tungsten E2 users should not use my piece of software!!! About the reset loop on TX. I´m working on a bug fix but it is very difficult since I don´t own a TX. I´m really sorry that happened to you, John Dale!

About the reset loop on TX. I´m working on a bug fix but it is very difficult since I don´t own a TX.

It did not help. I will try get the device replaced, but on my new device, UDMH only! I disconnected the battery, and reconnected it. It did not help.

Did you try to let the E2 deepdischarge itself? Generally, the Tungsten E2 is said to be a very flaky device in terms of memory expansion...for both UDMH and other apps. Best regards and sorry once again Tam Hanna Hi John,

Resetted. Ran LJP with a SNES ROM. Got a crash. T|E2 will not boot now. Does not do hard reset either. This is exactly what happened to me with UDMH v3. However v5 works fine. Once I get my palm replaced, I will certainly stay away from this application and go back to UDMH. I am very very unhappy! Installed this on my T|E2. Resetted. Ran LJP with a SNES ROM. Got a crash.

Kind of. I disabled UDMH, reset than I ran it a little bit and here is what I got from MemInfo: 19726064 Total Size (bytes) 28304080 Free Space (why it is more than Total? I dunno :-D) 16777200 Max Chunk So I ran Little John to see what an improvement it was and I got Super Mario RPG (an SNES 'Super FX' game) going at 23 FPS with no skipping, and sound enabled. After I quit I tried running ZDoomZ which has this huge blcok it tries to allocate, i think it was maybe 1k over my max chunk so it reset... :-( And it looped at that point and I warm reset -> uninstall MHH and my T|X is in tiptop shape again. So, I am mailing my findings to the developer in the hopes of a fix. Laterz, Ryan Well, at any rate, here is my results:
