I dont know why my lenovo A850+ lost his screen calibration. There is a frame on the lower position of the screen (where the spacebar on the keyboard is) where don't detect the finger, i calibrated it whith a program and worked again, but powering off and powering on the phone makes the calibration get "lost".
Now i tried to reinstall the original rom and i get a "welcome screen" again, and i can not get out of there because i can not hit the "next" button.... so i'm stacked.
Some ideas or solutions?
Thank you for reading ans sorry for my english....

I spilt some tea on my qtek s200 yesterday, and right after the spill, I unplugged the battery and dried it first with tissues and then a hair dryler .It seeed ok for a while but now I have a strange problem.Whenever I softreset the device, it sticks on the three color screen.
Softreset doesn't work at this stage so I try to hardreset the device.After I press camera+comm man+reset buttons, there is a confirmation message and then I press "yes", this is where,I think, the problem is; I can't get a format completed message and after this stage the device boots up normally.
After the spill, the camera button started to act weirdly. I open the camera app and try to shoot a photo by pressing the camera button but it doesn't react but whenever a turnoff the screen with the power button and on again it shoots a photo.
May be there is still some parts that need to be dried,so shall I dismantle it and take a look inside
If you have an idea, please have me informed.
Thanks.
To sum up the problem:
whenever I try to hardreset my ppc, it performs as a soft reset ,so,I cannot hardreset the device.
Help me please...
I wonder if one of the buttons (the camera button probably) is stuck. That would explain the entering bootloader and the inability to take a picture.
If you can get the device to boot up properly, in the settings under "System" there should be a "Clear Storage" program, that will allow you to do the same as a hard reset.
I tried that "clear storage" but that didn't work, all the same.Maybe you are right.Because when the bootloader screen came up, I tired to hardreset again,this time just pressing the comm manager button and reset the device with the stylus and it tried to hardreset but again was unable to do it.
So,i think, I should find a way to prevent the camera button from keeping pressed steadily.
Do you have an idea?
more likely the camera button have short circuited..
do u use usb cable to connect with pc .. if yes then after 3 color screen try to connect it and look if u see text at bottom left "usb" .. if its all true u can flash your ram
@sahir74,
When I connect the device on the three-color screen with the usb cable,i can see the "usb" on the bottom left.
I have no issues upgrading my qtek s200 (prophet), but when I try to hardreset, I come across a problem like this,or whenever I softreset the device, it doesn't normally boot up and just sticks at three-color screen.
Do you think a surgery can fix this problem?I am thinking about opening the device and doing something about the camera button.
All the problem arose when eye spilled a glass of tea on my s200 ,which happened exactly where the camera button is.
What ROM have you upgraded to? and, what is your devices IPL/SPL?
If you tried an official WM5 NVID ROM, then I think taking it apart and checking the connections is the only option...
Shadow 2
and I tired other roms, it seems to be a hardware problem.Anywayapart from this problem, I am using my device happily though.
Hi,
I've flashed my phone (HTC Touch Pro) with Hardspl and then the latest Energy ROM.
Everything went perfectly and I was impressesd with how simple and easy it was and how much difference the ROM made to the phone.
Today, while using the camera, the screen went blank.
I tryed turning the phone off, pulling battery and a hard reset but its still the same.
Even after hard reset, the screen is blank but if i press the power button, on the second press, I get a flash of whats on the screen and then it goes blank again.
Should I try to reflash the phone again?
I've searched but not found the same issue
Thanks
The touch screen is still working and sometimes i can see the display, but its very dark and hard to read. Is the flex cable that needs changing?
Why would it stop working so suddenly?
Should i take it apart to reseat it?
Ok, I've found the same issue in a few other peoples phones but they seem to have beeen resolved by sendin the phone back under warantee.
I dont have that option unfortunatly so need to find a fix.
The only thing wrong with the phone is the screen backlight that suddenly failed
Can anyone help me or point me in the right direction please? I cant find a definite diagnosis anywhere
New Flex cable?
New Screen?
Pray?
Thanks
Back to stock SPL and stock ROM
Still no luck
My sister just bought a Quantaray 7" Tablet from a co-worker. The biggest problem was that he forgot his pattern lock, so using the tablet was quite difficult. There was also a problem with it not wanting to DL directly from the marketplace. Screen was working perfectly.
In order to correct these problems, I did a factory reset and wiped cache via bootloader mode. That fixed the above problems, but made it so now the screen calibrations are inverted. Meaning that if I want to press the "1" button on the keyboard, I have to touch the "0", or touch "q" to register "p". In other words, (while being held vertically) I need to press the bottom right of the screen to hit a button on bottom left. I've tried completing the screen calibration during initial setup, but it won't allow me because its so far off.
Running; Android 2.1-Update1 and Kernel 2.6.29 root(at)localhost #154
TL;DR - Touch screen inverted after factory reset (touch on left to press button on right). Need solution.
sorry for the bump, but I'm hoping that someone could still help
Dear friends ..I have a problem and I hope that I find resolved by you
When the mobile is off then I turn it on The screen does not light up and the LG logo Do not appear and hear only the startup tone and wait for seconds and then press the power button Until the screen lights up.This also happens when charging Mobile When is off the charging indicator does not appear. I know it's a small problem but it is causing me distress.... The other problem is that NFC.. When press the button to turn this feature on does not respond ..... almost I did not show this problem until after the update to version 10i
Please I want a solution to these problems ..Note / I did factory settings, several times and I've also UPGRADE RECOVERY Without any result
thank you
