Have you tried any 2.1 stock rom? Maybe it's a hw problem ...

How many apps do you have installed? Might not have enough ram for it to run properly...also is it OC'd? I would just leave it at factory speed. Or like was mentioned it could be faulty hardware..put it in the oven.

It´s a Hardware failure definitely. The display, when i use the physical keyboard, don´t even show any image, it degrades. Tomorrow i´ll dismantle them, it should be the display flex or something. I´ll tell you tomorrow, thanks for de answers!

Nothing wrong with the display flex. Display is ok in portrait mode. Does the screen rotate properly to landscape mode with the keyboard closed - could be related to gyrosensor. But more likey the keyboard flex - the black one - is somehow interfering with the display addressing. (It is much easier to replace the key flex with the entire slider/cable assembly, if you can find a good used one.)

Thank you for the answer Saurus... I can´t find the screwdriver (torx 5) to open the display. I asked for the keyborad flex - the black one - and a can´t find it in Argentina. So i think my Dext has pass away, lol.-
Later i´ll tell you... Sorry for my English, I write the best I can.-

I suppose it's possible that the problem is condensation, but it appears it is directly related to opening the keyboard. Condensation is usually indicated by erratic autonomous activity seen on the display.

It's a complicated process. Be careful to write down each part and number/type of screws as you remove them, or you'll never get it back together again.
You need T-5 and T-4 screwdrivers. Small Torx sets are sold in most "big box" hardware stores.

I suspect your problem is the black keyboard cable attached to the slide rail assembly. eBay: dext

It is attached to the slider with tiny plastic rivets, staked with a heat iron. The rivets are neither available nor reusable, which is why I suggest you try to find a complete slide assembly (used) with a good cable. Otherwise a new cable might be attached with glue (silicone adhesive caulk) and clamp, but I have never tried that.

And bear in mind that I could be wrong - it may be something else, so avoid spending money before you identify the problem for certain.

As a workaround, you should be able to use the screen keyboard and keep the physical keyboard closed. Good luck.

It will also re-do any loose solders.

To remove condensation (jumpy screen) bake your phone at 250F/120C for 30-45 min. Solder melts at 350-450F/175-235C depending on alloy. CB process takes about 5 min. for preheat/ramp to melt/cool down cycle. At those temps the phone housing might turn into a gooey puddle before the solder, deep inside, would melt.
