Thanks in advance and sorry for my poor english! First charge the device fully, then use Time Machine (maybe you will need both Time Machines), then start from 1.5 again. If you bricked it, you are the first one to successfully do that... Link to comment Share on other sites More sharing options...

Thanks for your answer...when I put the phone with the charger it vibrates like when you start normally the phone but the screen remains black (but it´s not the same black than where I quit the battery...). And if I press red button, volume up and power button does the same but with the lights of the buttons flashing.... I don´t know how to do the upgrade because I´m blind...

Oh, sorry then... :lol: Your problem is very strange... Maybe it's a hardware problem, because I never saw anyone with the same problem as you...

Guest gusthy Posted September 30, 2010 Report Share Posted September 30, 2010 Are you really like... blind? How can you know what are you doing on your phone? I just mentioned charging phone because if battery is very-very low, pulse will charge without turning the screen on, and only the buttons are blinking slowly.

Hi, I charged the phone all night and still having the same problem...the buttons only blink when I turn on the phone pressing volume up+red key+power and blink very fast...

Guest Stevos Posted October 1, 2010 Report Share Posted October 1, 2010 Make sure you are charging with the mains power charger - I've had problems with it failing to charge over a USB connection. Also try booting with the mains power connected, but with the battery removed - might help if you have a dodgy battery. Link to comment Share on other sites More sharing options...

Thanks It is very easy to see if the problem is this battery thing or something else. Take the battery out of the device, and connect the phone to the charger, and see what' happening. If it turns on, then this is the problem. If not, not. Link to comment Share on other sites More sharing options...

Guest jgilalonso Posted January 9, 2012 Report Share Posted January 9, 2012 Hi, I know that this post is long time ago but I have the same problem. When I start my pulse, the buttons lights are blinking and the screen is always in black (with backlights on) if I execute in linux, "adb devices", this query don't return anything. Also, I can't enter in recovery mode because when I press red button+ volume up+power button the screen continue in black Did you solve this issue? Is it a HW problem or flashing ROM problem? Any idea? Thanks a lot. Link to comment Share on other sites More sharing options...

Any idea? Thanks a lot. 1. red button+ volume up+power button = "official rom install mode". It expects dload folder with official rom at root of your sd card. Refer here for details: Installing the Official 2.1 Update 2. red button + MENU + power button = recovery mode. Does it enter? 3. red button + volume DOWN + power button = fast boot mode (Blue screen). Does it enter? Edited January 9, 2012 by pier11 Link to comment Share on other sites More sharing options...

Only a vibration when i press the power button. I think that the only solution is GPG JTAG Box because the boot loader is corrupted. The same symptoms in this link Edited January 9, 2012 by jgilalonso Link to comment Share on other sites More sharing options...
Guest pier11 Posted January 9, 2012 Report Share Posted January 9, 2012 May be not exactly your case, but in somewhat problematic cases it helped some people to unpower the device, remove battery, and leave it like that for a while... Also our custom rom change process is not so sophisticated no corrupt bootloader... May be incompatible official rom is able to do that... Custom roms via CWR usually only change /system /boot /data partitions... Link to comment Share on other sites More sharing options...
