dr_bowtie Posted July 10, 2012 Posted July 10, 2012 Ok quick skinny.... My kid brought me this no name Android tablet that cant get to the home screen and its running Android 2.2. Apparently he's installed something or uninstalled something that wont allow it to boot properly. There is NO Name on this thing and the only info I can find is that it has a Via Arm926 CPU other than that there is NO info on the thing.... as soon as you hit the power button you get this message... SORRY The application wmtLauncher (process com.wmt.launcher) has stopped unexpectedly. please try again. (Force Close) I get a Black screen behind it and thats all... I get the top row of touch buttons with the Home (house) and Volume, Menu and Back buttons but they dont do anything... If I mess with hitting the Force Close a few times a screen pops up thats Fring the friends app... then it pops up the same error and that screen goes away.... It never loads any farther and the same error is repeated over and over....it doesnt load enough to get to the Settings button to do a factory reset from within.... I tried the Reset button on the side (tiny pinhole) but thats just a Hardware reset and did nothing for the software side... beings its no name I cant find instruction and I'lll bet they dont incluse the key press to do it manually... I tried holding down the Power and the Menu and Power and Volume and Power and Home and anytime you hold the power it will power cycle.... Everything I find on Google says do it via the settings icon but there has to be a way to do it manually like a cell phone where you hold certain keys during boot.... any idea??? EDIT: here is exactly what it looks like http://www.amazon.com/WM8650-Touchpad-Android-Tablet-Silver/dp/B008CC6Q8I Share this post Link to post Share on other sites More sharing options...

The Bright side is the error is gone... bad side it didnt work correctly.... I tried to reflash it and got the same issue. Flashed another rom and it bricked right at the back up old rom screen.... So today I learned how to Successfully brick a tablet Share this post Link to post Share on other sites More sharing options...

dr_bowtie Posted July 11, 2012 Posted July 11, 2012 been white screen bricking it all night and bringing it back with the WonderMedia WM8650 ROM most of the others are set for 800x480 resolution and the stock rom is 800x600 and changing the other roms env_boot doesnt help... currently the WM ROM always brings it back from bricked state but has no touch screen so I am fooling aroung modifying the env_boot file to see if I can get the touch screen working like it did in the beginning... been a long, long day and a decent learning curve simple lesson? dont buy a 60-80 dollar tablet... spend the money and get a good one... I am glad i didnt buy this Share this post Link to post Share on other sites More sharing options...
dr_bowtie Posted July 11, 2012 Posted July 11, 2012 good success today... been fooling around with the stock WM8650 ROM that I downloaded but is for an 8in tablet... that rom always brought it back from a white screen bricked state. I started trying to modify the stock rom with little to no success so i got the Uberoid v12beta ROM and tried that... it always resulted in a white screen bricked state. I then took the env_boot file from the stock ROM and swapped it with the Uberoid file... Still no work... I then had it mentioned to also swap the wmt_scriptcmd file from the stock rom and replace the Uberoid one... This worked and I was able to load versions of Uberoid to the tablet.... although all of them with no working touch screen or sound... mixing and matching various parts of the stock rom and the Uberoid stuff I figured out what worked and what didnt work... most all of it. I also joined the Tech Know forums where this is all from and got some direction there... if was a regular member who suggested I try a ROM build thats not even for my tablet by looks but he swears he has it for one just like mine and he modded the env_boot file and the wmt_scriptcmd file... Issue I had was the screen resolution was set to 8inch screen so i couldnt see what was doing when it was done... but the 7in Uberoid one white screens... The custom files set the flash screen correctly so i could see when the flash was done as I was just guessing and leaving it set 20 minutes each time....

dr_bowtie Posted July 12, 2012 Posted July 12, 2012 Yes Wev's and I owe it all to you buddy for coaxing my to try it and pointing me in the right direction. Had it not been for that it would have remained on my desk for a few weeks, months whenever my kid took it back home to prolly throw in the trash. I have flashed this tablet maybe 75 times over the 30 hour period and White screen bricking it 50 of those..... But now from the help of several people I have a fully working fully functioning tablet with WiFi.... if I was smart enough I can enable 3G and also turn this thing into a phone... wouldnt I look white and nerdy...LOL Share this post Link to post Share on other sites More sharing options...
