BRICKED tablet, completely dead 9" DMTECH 9458DCB - General Questions and Answers

My tablet got stuck on the boot screen (a 'bootloop') and so I downloaded the Swedish instructions, tools and firmware image files from the manufacturer's website. I installed the driver on my laptop, connected the tablet, flashed the latest firmware and got it working. Annoyingly, the Chrome browser would not work whatever I did, and eventually I tried to flash an older firmware image onto the tablet. This killed it completely. The screen shows nothing at all; you can just about tell that the backlight has come on due to a dim glow, but the screen is still blank.
The worst thing is that the laptop no longer detects that the tablet is connected to it. It does not even report it as an unknown device. This is what really worries me.
I've read other threads on this forum where Flashtools is advised for bricked phones, but will this work with a tablet where the computer cannot even detect the device is attached?
Any help will be much appreciated many thanks.

Go to a repair shop is the only solution
i can do any thing except damaging your device. GOD DOES NOT DO THAT

Yes, as @droid_god said the only way is a repair shop because they use those jtag devices to fix your phone.

[Q] Semi Bricked Phone

So sad. Just bought this phone. I tried to upgrade to ICS via but used the Galaxy S firmware (gti9000) by mistake...turns out ICS isn't out yet for my phone, the SPHD710. While flashing I managed to upload the "modem" file but when it was writing the file (it says "wait 2 minutes for write") odin froze.
and now..
Here's the situation. The phone will boot into the gti9000 firmware (i.e I get to home screen--so I think I'm semi-bricked), but WiFi won't work and the phone crashes a lot. Basically like a "safe-mode". Here are the conditions I'm dealing with
1) Windows 7 will not recognize phone when plugged in. It charges but does not show up in device manger
2) Odin does not recognize the phone at all. It was recognized for a split second on my laptop when I was installing/reinstalling drivers. Can't replicate this.
So basically I'm stuck. I tried going into recovery mode and applying update from SDcard (to revert to stock) but i the SD card won't mount
Anybody help??? PLEASE. I don't want a $500 paperweight.
I can give as many details as you like.
Thanks so much!

[q] hard bricket tablet ippo q78

Hello everyone, I bought a brand new IPPO Q78 (Android 4.0.4) via focalprice.com 2 month ago. First day of using it, and by using I mean simply installing a few apps, and after reboot, I got BOOT LOOP problem, so it wasn't able to get to tablets home screen. After lot of reading about similar problems, I was able to successfully unbrick it using (I suggest others with same cheap china tablet that are also soft bricked to use this program, it really was the only one which helped me):
http://forum.gsmhosting.com/vbb/f781/android-tablet-wifi-cpu-a10-a13-wipe-rom-easy-zakir-gsm-1656461
Here is my situation now, you can view it:
http://www.youtube.com/watch?v=cU1KYIrvZWI
Before, when it was soft bricked, at least after this android logo came the android animation that looped forever, but my computer was able to recognize and install the drivers for Android ADB device, now it can't, it won't recognize my tablet no matter what, ONLY when I press volume up and connect it to usb port, then it recognizes and installs vid_1f3a_pid_efe8 driver, which also I cannot use with LiveSuite, why? I really don't know, I've tried every possible solution found on forums (mainly here, but elsewhere also).
Whole this situation is a result of me doing the CWM upgrade/install, I'm a newbie, so I cannot tell for sure what was it, I just know it was from xda--developers forum, more accurately this thread:
http://forum.xda-developers.com/showthread.php?t=2189640
after this, poof. I think it is hard bricked, and my question is, is there a way to flash it (btw, tablet is rooted) by only having access through mentioned driver vid_1f3a_pid_efe8 and without LiveSuit, cause I would have to download and try a 100 ROM's before I pin the one that suits my tablet. It's really a tough program to deal with, but if it's the only one, I would gladly format and reinstall my Windows OS as many times I need to to get it working.

[Q] LG optimus pro G bricked after using exitrecovery.zip

hello,
I hope someone can help me with my AT&T LG Optimus Pro G phone, which I have royally screwed up.
I was experimenting with the cyogen mod and after installation I installed the freegee app and once the cwm recovery was installed, I decided to go into the recovery by holding down up volume and power button.
Once I was in recovery for CWM i couldn't exit out, and the phone constantly booted into recovery after every reboot, even if i took out the battery, and powered it on.
I tried reflashing the cynogen mod through the sd card, and even though I would get success message the phone would still reboot into the cwm recovery.
I started doing research on the internet and i found file exitrecovery.zip that could be used to possibly get the phone out of the cwm recovery.
After installing exitrecovery.zip, I rebooted the phone, and now I have complete black screen. There are no light, no hints the phone is even turning on, and I can't get into recovery( or at least I can't tell). The only thing now is that when i connect the phone to the computer the window tries to install drivers for the device, and eventually prompts to insert a CD for LG drivers. I already have LGUnitedMobileDriver v.3.10.1 connection drivers installed from their website.
Please help, I am really stuck here..... and have no clue what to do. I am fairly new with rooting and modding, and I am extremely miserable.
The phone is still under warranty from LG. Anyone if all else fails, and since the phone has no screen or lights, whether they would replace it?
Attaching the exitrecovery.zip that I used.
sobbing....

hi, thanks for your reply. Again I very much new to the rooting and android OS tinkering, and nowhere close to an experienced user.
I tried to use google with your information in regards to how to use flow ROM with expansion.exe, but did not get any leads.
I would appreciate if you could elaborate more on this process.
When my phone is connect to the computer via usb is is constantly trying to install drivers. I had already installed LG usb connection drivers in the past and it was successful. It almost seems it tries to install driver yet fails after receiving no input from the phone, and then request LG CD with drivers.

Try to find driver on the web-site of producer. Set them. Overload a vehicle in Bootloader. In the controller of devices on компе must be determined your device. Then on a computer start sewing - .EXE.
Did you get this problem resolved? I have the exact problem with the exact phone!!!
thank you very much

My Tablet won't boot

Hi,
I just got an Arnova 10D G3 and it doesn't boot. All I get is the "Arnova" logo on a black screen. I bought it on a refurbished condition, it was a pretty good deal so I am ready to do any risky procedure to make it work since I don't have much to lose.
I downloaded the latest firmware from the official website but I am unable to use it because I can't access the recovery mode. When I try to, the tablet reboots while loading this mode, without even showing a menu.
When I connect the tablet to my laptop on Linux, nothing happens. On Windows 8, there is an "Android" device shown at the bottom (in the task bar), but the tablet doesn't appear as a drive.
How can I fix this? Is there a way to somehow force the re-installation of Android?
Thanks
PS : It is my first post on this website, so I hope I'm in the right section.

[Q] Numerous Issues Z3V

I have the Xperia Z3V. Model D6708, firmware version 23.0.E.1.44. I have recently tried rooting my device (as per the steps found here: http://forum.xda-developers.com/z3/xperia-z3v-general/guide-sony-xperia-z3v-t3100402). I have run into numerous issues with this, as well as an unrelated issue.
As far as the rooting process, I have gotten flashtool and the ftf file downloaded and setup. I have successfully sent my phone into flash mode. Where I run into issues is as soon as I choose the firmware version to flash (located in the .flashtool/firmwares/Downloads directory) it will prepare the files for flashing, but as soon as it starts it errors out and tells me I need drivers for my phone.
So I go to get the drivers, I download them directly from here: http://developer.sonymobile.com/downloads/drivers/xperia-z3-driver/ . They don't work when installed manually through Windows device manager, I Google the issue and see that I should just use the PC companion. I get that all downloaded and setup, and a new issue arises. Initially my phone doesn't get detected in MTP, MSC, or debug mode so I mess with it a bit and have it auto detect. Finally it detects my device and starts attempting to get drivers, but on the last step it says PC companion needs to update, even though it already had, and is the latest version from Sony's website. Eventually it gets to a point where it goes through attempting to install my drivers but at the end, a new issue; "Sorry, the phone/tablet does not work with PC Companion.".
So what the hell am I supposed to do? Even Sony apparently doesn't know what to do with my phone. I have tried everything I can reasonably imagine. Reboots, factory resets, different modes of reboots. I cannot for the life of my get anything to work with this blasted phone.
To add to this frustration (and the whole reason for me trying this in the first place) is the phone has been doing the sleep of death recently. I have only had this phone for a little over a month and it has gone into the SOD 4 separate times. I have not dropped it, I have not water tested it, and I have not altered the software (since it appears to be f**** impossible anyways).
Any and all help is greatly appreciated. I really wanted to love this phone, but it has been a complete nightmare so far. Not aided by the fact of course that it's through Verizon so I'm sure their special brand of f*** you is tossed in here.
