Blackview Tab 8 / black screen, bricked / repair? - General Questions and Answers

hi all,
my new "blackview tab 8" got stuck during normal updates (after 30 mins of working with the tab). i did a softreset but it wouldn't boot anymore. i just saw the boot screen.
a few tries later, i don't see anything on the screen, i can't go into recovery mode, my computer can't find the device (I tried the adb script thas has been linked in some how-to für newbies ). the only thing it reacts to, if i hold the power button reaaaaaaaaaaally long - like 30-40 sec. then it vibrates, but nothing more happens afterwards.
there's also a tiny hole (not the one for SIM / SD) in which i poked around in the hopes that this will be a reset switch, too. and there is actually a button inside - but it doesn't do anything for me.
so, i wasn't doing any flashing, but i guess, this forum is the best source for the answer as you see a lot of bricked phones
i got the money back so i can now try to repair it myself. i already disconnected the battery and reconnected it, but that didn't help. what could be defective? is there something that i can do / test / replace?
cheers

Daxian X999 / T32 hard reset help needed

I'm not sure how many people, if any, have experience with this phone, but I'm taking a shot in the dark because I am completely out of options here. The phone is similar to the Cect M88, and the other Cect iPhone-clones available, although I'm not sure how similar the button layout is.
I installed PCM Keyboard last night, and all was working fine until this afternoon, when all of a sudden, my phone wouldn't wake up. I ended up having to pull the battery in order to get it to restart, but then it wouldn't boot past the Windows Mobile screen (the first one - didn't even make it to the second screen).
After several attempts to hard reset (top volume button + camera button + power button), I was able to get it reset, but even though active sync was running, folders weren't showing up properly on the phone itself. I did a soft reset, and folders then showed up, but this time active sync wouldn't load on the phone. Several more soft resets did nothing, but I kept trying, and finally... the phone froze up again to the point where it hung on the Windows Mobile screen again. Now, despite all attempts, I can't even get it to hard reset. When I push all buttons from an off state, the screen will turn blue (which seems to indicate some kind of resetting is going on since it normally goes straight to the WM screen) and then a few seconds later, the Windows Mobile screen will come up and hang. I've tried every combination of buttons possible, and I've tried hard resetting probably a good 20-30 times since this happened. I've removed the SIM card, removed the SD card... I've basically tried hard resetting seemingly every way possible, and yet it still will not reset and load up WM 6.0 pro like it should.
Any ideas on how I can get this thing to at least move past the WM screen? If I'm totally unable to hard reset, what would be the next best course of action? Since this is an off-brand phone with no support or any kind of warranty, are there repair places out there that can restore the OS? Is that something I can do myself? (Phone didn't come with any software or anything.) I'm at a loss here... I really don't want to end up with a $200 blue flashlight/paperweight. I know I took my chances when I bought it, but well... this stinks.

hey man i know its old and hopefully you still have your phone.. ok what you need to do is let the phone die completely so you may have to keep the blue screen on and keep turning it on till your phone does this like you i have hard reseted serveral time to no avail but when the phone died i took out the battery plugged it in to the wall charger placed the battery in the phone let the red led light by the camera light up then i turned it on and before the screen could show the splash i did the hard reset phone is aye ok !! hope this helps man.. your post helped me..

HELP: Touchpad/screen doesn't respond, can't enter bootmode/security code or PIN code

First of, I have a problem getting into the bootloader as I've said in my post: forum . xda-developers . com / showthread.php?t=759279
I've been using Kostas244's ROM -> www . forum . xda-developers . com / showthread.php?t=554071 for a few months now, no problems until now.
What happened: The touchscreen began to not respond to my input, slowly and gradually for a few days. I clicked on a few things, something else was triggered. So I figured I only had to reboot the phone. Now I can't get even use my phone.
My phone activies: Calls, SMS, Alarm, Play Solitaire, Taking Photos. That's about it. Nothing else.
Now I can't seem to enter the bootloader (Camera Hold + Power) during startup, can't get into the system cause the slider reacts just once and then it hungs up. Freezes for a while, then after I shut down the screen and turn it on again it simply does not respond at all.
First time I could enter my security code, but then I couldn't enter my PIN code so I took out my SIM CARD - then I couldn't enter my security code and nothing seems to be working.
Right now my phone ask me to enter a code due to "several bad atempts to get into the phone" and I could only press q (whatever I would input, it simply gave me a q and then nothing) and that doesn't do me any good.
Just a few minutes ago I tried forum . xda-developers . com / showthread.php?t=636170&highlight=bricked+my+cruise&page=2 on the thread ( forum xda-developers com / showthread.php?t=636170&highlight=bricked+my+cruise&page=2 ) who seemed to have a similiar problem as mine - the touchscreen isn't working.
But I don't have Windows XP (if that's the case it's not working) and the guides seems to point that it has to be in RGB mode (bootloader) and that is not working either.
Does anyone have any ideas or solutions I could try? This just happened out of the blue, I hadn't done anything with the phone for a whole day and it just began acting like this. No damage to the phone has been made or anything out of the ordinary. So it sounds like a software problem, but I can't seem to get past it.
I use Linux 64 and Windows 7 64 if there's solution to connect to the device on either Operating Systems.
Thanks anyway.
To enter the bootloader screen press the camera button an the reset button at the bottom of your phone 'the little hole next to the usb'.
You could try hard reset press and hold both bottom buttons and reset 'you will lose your contacts sms ect' so back up using pimbackup.
If your digitizer is not working 'doesn't respond to touch' try sync your phone and install mymobiler/,then you can browse you phone and backup to sd card before hard reset.
Already tried that, as I included in my previous post about getting access to the bootloader. I can't get into the bootloader with Camera Hold + Reset. Nothing happens, it's as if the buttons don't respond correctly.
Hold down both "bottom buttons"? You mean GPS and IE buttons? Tried that too. Tried a few others. And I'm certain this worked before. Like I said in my post, nothing has happened to the phone recently - it just started acting this way. So I'm guessing it's more a software problem than a hardware problem. Since I have HARD SPL and a homecooked OS the chances of it being that is a probability.
I have nothing that needs to be backed up, so I don't need to do anything about that.
Hi
I have same problem. Screen doesn't react (only if press hard), and i can't enter bootloader and make HR.
Also, I had same problem 2 month ago. But I managed to revive it - made a lot of try of HR and one of them was successful. but now it is dead again and I don't know what to do...

Request: Surface 2 Recovery USB. Won't boot, flashing 'Surface' every 8 seconds

Hi, so yesterday after powering my Surface 2 down (it was working fine), it no longer boots up. Instead, it will show the 'Surface' on the screen for about a second, and then the screen will go black for 8 seconds, and repeat until I turn it off or the battery dies.
I've been having a hard time finding other people with this problem, but the few I did said that sending it to MS (and getting a new one) is what they had to do. One person did say that they were able to fix the problem with a bootable Surface 2 recovery USB. I have a lot of work on my surface that I don't have copies of, and would really like to be able to save those files.
Things I have tried: Holding the power button with a combination of volume rocker/home key. Holding the power button for 20 seconds followed by 2 seconds off and on. I have fully charged it and know it has enough battery.
Help would be greatly appreciated.
Hi John,
What was the solution to fi this problem?
I encounter the same problem.
Regards,
Hans
You should be saving your stuff to your OneDrive...anywho
If you have a USB recovery drive, you could try booting from it and doing a refresh,(NOT a reset) that would keep your files.
If you don't have a USB recovery drive you could make one using the 8.1 RTM ISO, I wrote a how-to guide here;
http://forums.wpcentral.com/microso...w-install-windows-rt-8-1-rtm-surface-2-a.html
or you could download one here;

(I think that one is for the UK, but that shouldn't matter, just do a full reset from your recovery once you get your files off)
Hope this helps.

[Completed] [Q] Sprint Galaxy S5 Sport Brick? Bootloop.

I wanted to solve this problem on my own but after almost 6 hours I just can't figure it out. Its either totally bricked or I'm just missing something simple. I've seen many people complain about this problem but none of them seem to have had the same problem I do. Thing is I was just really starting to love the way I had the phone set up. DAMN!
I used this thread to root: (CF)
http://forum.xda-developers.com/sprint-galaxy-s5/help/q-root-galaxy-s5-sport-sm-860p-t2859473
SPRINT GALAXY S5 SPORT SM-G860P
Android 4.4
I had CW recovery installed
(wish I had more info about the software)
Here's whats happening:
START
(vibrate)
RECOVERY BOOTING...
RECOVERY IS NOT SEANDROID ENFORCING
Set Warranty Bit : recovery
(Also on Screen are the logos)
Samsung Galaxy S5 Sport
Powered by Android
This stays on for about 10 seconds.
Then blank screen (2 seconds)
(vibrate)
Screen still blank (2 seconds)
REPEAT (Auto reboot and goes back to start)
Other notes:
Trying to boot into recovery (home+vol up+power) Nothing Happens
Try to power off and nothing happens.
Pulled battery, did the 30 sec and restarted no change.
I have all updated usb drivers.
Odin will not see the device because its not on long enough. (Kies didn't see it either.)
Plug into PC via usb - Nothing Happens, device doesn't even show up because its not on long enough (win 8.1 and 7)
Pull battery to get it to stop, once battery goes back in, it auto starts again.
I TRIED AS MANY SD CARD / BATTERY/USB CABLE/POWER CABLE/BATTERY PULL/BUTTON COMBINATIONS AS I COULD FIND ONLINE AND THEN SOME. No Luck with anything.
I know this isn't a "help desk" I just wanted to give as much info as possible hoping to help you help me!
Please point me in the right direction.
Thanks!
Try to hard-reset your phone. There is a button combination for that., search it over the internet.
Thanks for the reply.
Unfortunately the hard reset combo does nothing. I've tried every button combination that I have been able to find with no luck. Factory reset, hard reset, etc. etc. no luck. I've also searched for a possible "hidden" button underneath the back cover or something of the like...nothing.
hmmmm
At least, it is not hard-bricked. So there is hope.
Have you checked if it is entering the download mode? If not, then try it. You can use this mode to flash file via the PC.
Check this link
It worked! Obviously I didn't search or try as many things as I thought I did. : / I can't thank you enough! wow. Amazing!
Thread closed.

Please help me with my phone.

Hey everyone who reads this.
I'd like to start my topic with apologising if I post this in the wrong section.
So, I have a LG Spirit H440N LTE for about 3 years now, maybe a little less. I've always taken good care of it, both physically and in updates / security wise aswell.
My phone has been working flawlessly until the last 2 days. 2 days ago i was charging my phone, and when it vibrated (meaning its 100%) I pulled the cable off, and pressed the power button (power button locks - unlocks the screen) the screen didn't turn on. I was like "wow that's strange" but didn't care much, i just kept pressing the button every 5-6 seconds, nothing.
At that point I pulled the battery out, let it sit for a short time and then put it back, start the phone, I felt the vibration (meaning it's starting up) but no screen, so my first idea was that I need to get a new firmware and completely reinstall my phone, as it seems like it got bricked.. for no reason, by itself ? Strange thing but I accepted it and literally been googling for 9 hours now and I find more and more issues.
After I got LG FlashTool, drivers, and even 3 different firmwares, I wanted to start the phone in download mode to start upgrading, but even though I held down "volume up for 5 seconds and then put the usb cable in" nothing happened, no screen, my PC didn't recognise the phone either.
So I got a little bit mad and pulled the cable out from the phone, I wanted to remove the battery, but out of nowhere the phone suddenly started loading in, screen working completely fine, i could do whatever i want, so my first thing was to do a hard reset. After the hard reset I set up my usual stuff (important apps etc) and I locked the screen so my battery won't go down. Little did I know, I ****ed up again, because ever since that happened, I can't get my screen to work again. I tried everything I could but my PC still doesn't recognise the phone (even after a LOT of drivers being installed), charging the phone doesn't do anything. Regardless if I remove - put back the battery no screen, no screen in download - hard reset mode either, it's just completely black.
I'd like to have some sort of help, because I am just completely out of ideas, I really feel like a firmware change could fix the phone, but if the computer doesn't recognise it, I have no idea what to do.

You might be having hardware issues, such as a faulty power button. If you are the type of user that frequently presses the power button to lock/unlock the screen, this leads to excessive wear on the button components, this is why some users prefer to use the "tap to sleep" and "tap to wake" feature, to avoid wearing the power button out. On my LG, this feature is called "KnockOn", it's located in Accessibility settings.
