[Q] phone powers on but no screen display at all? - myTouch 4G Q&A, Help & Troubleshooting

Ok, So im new, name is shade...
I have a HTC Glaicer, mytouch 4g phone..
im having a problem where the screen is not turning on at all.. It charges, when i turn it on normally, it vibrates once, and putting a new sd card into formats it with all the directories and such, so im assuming i dont have a bricked phone... im very new to adb, but have been doing some reading on it and have a simple understanding to it. When i plug my phone into the computer it will show up android 1.0 if i try to go into hboot? (power + Vol Down button) or it switches to mass media mode once it boots (im assuming it boots because it formats the sdcard). so im wondering what symptoms aside from a hardware problem that this would fit under. im trying to get adb to recognize the device, searched through mny threads and drivers, now im redownloading the sdk on a diffrent machine to try and do adb.. i got the phone in this condition and have no idea what was done to it, i tried to boot to cwm and no dice for the screen displaying anything, i also have no sound. any ideas?

it sounds like a ribbon cable possibly loose inside or bad lcd that would be my guess if no display and it vibrates when powering on!.would be safe to wait for some other replies to back this theory up!!!

m hopeing thats what it is.. does abd require the phone to be in debug mode for it to work at all? i can see it perfectly with the computer, im just stumped. i can change lcd screens and what not, just Want to make sure thats what the problem is.

[q] help! Bricked samsung intercept!

Last year(late 2010, maybe mid November), I rooted my phone and flashed recovery with no problem s at all. Some time after that I added Apps2SD and that went smoothly with no problems for about a week. I purchased an 8 GB SD Card for more storage room and after I partitioned it and switched the cards my phone started acting up so i rebooted it. After that I was stuck in a boot loop, so i tried to flash it back to stock but it wouldn't take to it no matter how I tried, whether it be through recovery or SW Update. So then I tried Odin Multi loader(cant remember which version but at the time I made sure it was the one meant for the Intercept) after I flashed it with the Stock through Odin, the phone bricked. Now it will not turn on in any way(recovery or other) the only thing it does do is vibrate when I plug it in to a computer, and it will occasionally show battery life through the touch screen and keyboard buttons by lighting them, but as soon as the it is unplugged it is a brick. I see the little bit of functionality as a little bit of to be able to fix this phone whether through ADB or another function but I desperately need help with this. Can someone please help me fix this phone?
note: I currently have a Samsung Transform as my main phone so if the Intercept can't be helped then it's not that big of a problem.
I have the same problem! Please help!
When you root a phone you put the rom, and recovery onto the sd card. changing sd cards disrupts this process. Put the old sd card in and tell me what happens.
The phone doesnt come on at all
see if you can get it into download mode with the battery out.
Pull battery
connect to computer with usb
vol down + camera + end
If you get into download mode this way flash the stock.tar using SWUpdater.
Nope, it doesnt work, thx though
Ok I've got the same problem with my intercept as well, So i just like to add (maybe its just me) that when i plug my phone to the computer the phone shows that its still functions right (without the screen on), I'm able to make calls, and receive them as well (with the touch of the answer button) but just the screen doesn't turn on, AT ALL!, so KJON i don't know if your having the same problem as me but I'm just a noob and i wouldn't know what to do. But there's some ammo if you need it.
I HAVE THE SAME PROBLEM! i dont even know where /sdcard/sdx/zip/ is!
My phone is also a samsung transform and not and intercept and whenever i press vol down+ Power, only the function buttons at the bottoms light up but not the screen
i am a noob.
help?
noooooob here...i didnt wanna start another thread since i have this same problem, so i hope someone reads this..
couple days ago i bricked my sprint intercept i was using SWu and forgot to take the Binary files for the Moment out so now i cant get my phone to DL mode, ive been searching since saturday night and have tried every Button combo posted and nothing, my phone will not turn on and ofcourse it isnt recognized by my pc BUT, ive noticed that only when its plugged in to the computer after trying to power it up several times it´ll vibrate then the 4 touch buttons will react to either the call or end button, also it makes the low battery sound and if i press the camera button it makes the volume sound but i CANT get to download mode, can i bring my phone back or is it done with? help please! and thanks in advance...
well, i would say boot into rrecovery by making the phone off either power button, or remove and replace battery.
next, you will need to press and hold in order: power/end call, call, and volume down.. this should boot recovery mode.
lastly, use the red scroll device to go to reset facory defaults or factory recovery, use common sense while looking. select with clicking and use arrow back button to go back to recovery main, then reboot to system. easy as pie.
Have you tried ODIN or ADB?
I have flashed the Intercept numerous times, soft bricked more than once, I was always able to recover using either the stock bootloader, CWM recovery, or flashing the ROM/Kernel directly using ODIN or ADB.
If you are still having these issues drop me a line and I'll gather some links together that should get you back up and running.
If the phone will not boot at all, even with a charged battery, I would definately try contacting Virgin Mobile and escalating the issue. I've had plenty of luck replacing devices claiming that the device just dropped dead without notice. They are usually good about sending out a replacement phone, and on rare occasions even giving you an upgraded unit if they are out of stock.
Good luck!
Did you use Odin or the swupdater?
Bug difference. Sounds like there's a missing boot loader.

Hi, did you guys fix your bricked phones? Today I have bricked my Samsung transform (bad flash went with SW upgrade.
Only vibrates sometimes and the buttons flash a little, but no boot at all. Is there any chance to fix it? even with Jtag?

[Q] BSOD + new computer without adb drivers = ermmm...

Ok this might seem strange, and just bare with me if I'm being thick...
I have had a nose around the forums and done a search but I couldn't find a solution to my problem.
I installed CM6 (by bumblebee) on my vega via CWM and instantly got BSOD - I didn't really think this was a problem because I knew the risk that it might happen and I had already done a backup etc.
However, all the parts for my new computer arrived the next day so I forget about my BSOD vega for a week as I started building my new computer and setting it up etc etc
I just got round to sorting my vega out when I realised I had completely wiped my old laptop with all the adb drivers on it etc (because I was going to sell it). Therefore, I cant get into recovery or flash anything to it because I cant use any adb commands :s (I cant reinstall the drivers - windows wont recognise the device as adb, only as a mobile device...).
Any suggestions? Am I being thick? Thank you for taking time to read through my rambling post anyway
You should be able to get into recovery and re-flash a stock rom. Make sure the device is plugged into the power and usb. Open device manager in win 7. Then hold down the back button for 2 secs then while still holding back hold power for 2 secs then release power but keep back button down for 2 more secs under universal serial bus controllers a new device should pop up. Point that at the usb drivers from the advent website. When the drivers have installed the screen on the vega will still be black but you should be able to flash the stock rom and start again.
Hope that helps
I will give that a try thanks for your help
Ok this is strange :S
EDIT: Drivers updated! But:
It only stays in APX mode for a couple of seconds before turning itself off - I know there is enough battery because I have booted it and left it for at least 10 minutes hanging in BSOD...
EDIT2: Ok, things have got worse:
- manged to flash stock image, booted in to 1.08
- flashed clockworkmod
- got into CWM and preceded to restore
- restore froze whilst restoring dalvik cache...
- left for an hour, no change
- decided best thing to do was to turn off device and boot again
- device boots, hangs
- used adb to reboot
- now wont even get to the 'booting...' screen, adb and pc wont detec device anymore
- tried to get to apx mode, works but my pc wont detect it so cant flash stock image again...
Sounds bricked anyone got any ideas? I know it was probably a stupid idea to switch it off whilst it was restoring but it was definitely frozen.

Keep trying to put it into recovery mode. At times it gets picky and you have to time it just right. Took me several attempts before it worked correctly again, so keep at it
Also, be sure to keep the USB plugged in while you are attempting to get it into recovery-mode and your sound turned up so you hear the infamous hardware-connected sound. Once you hear it, immediately plug in the power and start the recovery-flash. Do not wait too long or you'll have to start from scratch again
Keep at it, you're almost there.
Got there in the end thanks for your help!

Do i have to accses phone or is it sd card cuz i have had trouble with getting it to cennect to my pc
umm..
keep trying Download mode should work as long as your phone has some-sort of lighting up and stuff.
You might be HARDWARE LOCKED, meaning that the volume buttons won't work for you.
You may want to try a JIG. you can see how to build or buy here: http://www.youtube.com/watch?v=Rdn5GoRjhn0
it says captivate but its the same.
a question to you; has you ever been into download mode, or recovery mode without being in the rom, but using the volume buttons to get into it?
I Fixed my phone thanks so much if my mom would have found out she would have killed me i only had phone for 5 days now thanks so much i am back up and running no more flashing for me i am just gonna root now until i learn more about it

Secure booting Error!

Hello, about a weekago I've installed dorimanx kernel for my D802 and today I realized that it made my 3g connection unstable
I decided to flash back to the stock kernel which I backed up before flashing dorimanx, but something went wrong. I really don't know what.
The phone won't turn on, it keeps showing LG logo and showing Secure booting error. Cause: boot certification verify. (1001)
I tried pretty much everything in the past 6 hours and i'm losing my mind.
LG PC suite or any LG pc software won't recognize the phone when plugged with USB, and everytime I plug in the phone to my PC windows opens 15 boxes of "new hard drive detected, format needed to use" (here's a picture)
Also tried following this post: http://forum.xda-developers.com/showthread.php?t=2582142, but no luck. It seems like my dev folder is missing alot of sub-folders for some reason.
Anyway I'm really lost. Can you guys please help me to solve this? I would really appreciate it.
Thanks.
To be sure, have you already tried to get into TWRP through the factory reset key combination?
I tried almost every combination possible. the phone simply resets itself to the same situation, screen is on but black and nothing else happens
After holding power+down buttons the LG logo comes up and disappears in a snap, like something is wrong.

Your device is unplugged while you do this right? It has to be completely turned off before doing the combination, and while plugged in, it just doesn't turn off completely.
Yes, it is unplugged while I do it
You'll need to hold the volume down + power key as you turn the phone on, then re-press them when the LG logo shows up to get to the factory reset page. Just verifying the simplest solution before I go in depth with this.
If your phone still won't get into TWRP, try this: plug the phone in to your computer, and open device manager (right click computer > manage) and under portable devices, locate your phone. Once you find it, right click it, click uninstall, and once that's done, unplug your G2 and reboot the PC. Once it boots up, plug your G2 back in and let it reinstall the drivers and try to do the guide again. Best of luck!
EDIT: I just realized the guide you are looking at requires Ubuntu. Are you aware of this?
double edit: http://forum.xda-developers.com/showthread.php?t=2432476
Let me know if you've tried this guide yet.
I believe you're using vistual machine for ubuntu.
Well, if you keep getting 15 messages about formating drives (in windows) when you plug your phone to ubuntu you will not get your patitions in ubuntu.
So you should close the messages asking you to format drives, then open vmware in full screen mode, then plug your phone to computer and follow the guide http://forum.xda-developers.com/showthread.php?t=2582142. I'm sure in this case you will get your phone partitions showing is dev/sdb.
Even if you don't get those partitions keep trying several times untill you succeed.
Good luck.
Thank you!
Apparently I was using the key combination wrong.
And yes I was using ubuntu on a VM.

help pls, nexus 4 softbricked

Hi guys,
I had Pure nexus rom installed:
http://forum.xda-developers.com/nexus-4/development/rom-pure-nexus-project-layers-t3237366
and everything worked fine for weeks. Yesterday I noticed that my nexus 4 is using battery too much, without any reason.. Then my phone turned off, try to restart but it was stuck on google logo. At that point there was 20 or 30% battery left. I boot it to recovery, wipe everything and tried to restore factory settings, cos I didnt have any backup on phone. But again it was stuck on google logo.
So now I cant boot it cos there's no system installed on it, basicaly there is nothing on my phone. I tried Nexus Root Toolkit, but my pc dont recognize my phone, when I boot to recovery it's still the same, so I cant install drivers..
At this point, I have no idea what to do.. Can anyone help pls?
Thx
Can you get into fastboot? Are you using Win7? Tried different USB ports and cables?

Thx for quick reply !
Yes, I'm using win7 64x, I tried all usb ports and 3 different cables and nothing. I can get into fastboot and recovery, but pc still don't recognize anything..
i am currently under the same situation
only difference is i can still fastboot and flash a recovery (twrp for that matter)
afterwards, when booting to recovery - i can install a rom
once the rom is installed, reboot does not boot into the ROM and instead just displays the google logo - then vibrates a little - then the screen turns off
I just tried on 2 other win7 pc's, still nothing.. Nexus root toolkit just can't establish adb/fastboot connection..
edit: other thing I tried is to copy ROM file on usb stick, and then connect usb stick with micro usb cable to phone, and when I'm in recovery (twrp 3.0.2-0) there is just ''internal storage'' option.. Is that normal, should twrp see external USB drive? Cos I'm thinking that maybe something is wrong with usb charging port (I replaced that board month ago).
Hi,
I have a similar problem:
I had my mobile in working condition and once when upgrading the OS to 5.0.1, it downloaded the OS and was upgrading. During that process, the charge got over and hence the phone was shutdown. There after, it was not proceeding further from Google screen when trying to reboot. So, i thought battery is dead and replaced the battery with a new one. Now, i am getting the following problem:
The phone doesn't turn on(not even getting GOOGLE screen now). But, If I keep holding power button and Volume down button and try to insert the charging cable immediately then i get the boot menu but it wont stay there for even a second and goes to GOOGLE logo screen and gets shut down. Please help me with this.
Hi guys,
I menaged to fix the problem, my problem was charging port (smal L shaped board) that I replaced month ago. That's why there was no connection.
I got another one this morning from ebay, and Nexus Root Toolkit established connection immediately.

That looks like a stuck power button.
Try just holding the volume down button and plugging the charger.
If you see the fastboot screen, you have a stuck power button.
Just experienced this issue on a Nexus 5 and I was able to recover from it by "massaging" the power button for a while.
