Hello. I have problem tablet Overmax Quattor 10+ (my friend give it to me, becouse she pushed too hard power on button, so I had to open tablet and repair it by home-made solution). Everything gone perfect, tablet went on to the PIN screen. I asked her if she know it, but she said that the tablet hadn't any PIN secure. I was searching a lot how to crack PIN (not for SIMcard, just Android secure), but I didnt find anything so I started to install software again. I downloaded everything from here : overmax site. After download I pressed HomeButton connected to PC, program has found the device and asked me to format or not device. I pressed yes, the formatting went to 4% and device has disconnected (I didnt touch the USB cable or something). After this tablet couldn't boot (nothing show on screen), when I try again to format it, the program show info, that the Tablet or system image is incorrect. Windows detect the device in Device Manager. Anyone have solution for this?
Thank you in advice. Greetings.

Hi,
Before posting my problem I've searched this forum and google, but didn't find any solution.
I've got for present faulty XDA II. The owner said he was trying something with software/unlocking and he ended with bricked PDA. It's impossible to load Windows, I've tried all possible key combinations, resets, etc. The XDA II wasn't repaired or damaged physically.
The only way I see some signs of life, that the bootloader is fine, I can see v.1.06 and Serial, and when I connect to PC, it shows USB. But when I try to upgrade ROM, after I press Upgrade, the screen becomes blank and then PC says "connection error".
In few moments I saw on bootloader "DOC FILE IS ERROR" or smth.
I tried to connect with mtty.exe, but it doesn't find USB port as it finds in other my fully working Himalaya.
Is there any chances I can fix it, or just sell it for parts?
you can try it to flash with your sd card
with your working device you get the files which needed for the sd card mathod.
wish u all the best.
Hi guys!
Like my brother said: if they don't know it at XDA, there is simply not a solution yet. And having tried a lot of options myself, your expertise is wanted!
How it all began:
I wanted to update my Lumia, so used CAB sender. Fine so far, but there was a bug (no keyboard) so I wanted to repair with Zune. Didn't work, it said it was impossible to repair to the previous version (code 80180083). And since it didn't started up now anymore, it bricked.
Looking for a solution, my laptop OS (Windows Vista 32-bit) didn't recognized my phone anymore as Nokia Lumia 800, but simply as 800. And now, it only recognises my phone as Unkown Device (Qualcomm CDMA Technologies MSM). And Windows does not detects a proper driver for this thing. Tried Nokia USB Connectivity, WindowsUSB and the drivers belonging to Nokia Care Suite but nothing gets it done.

I thought I found the solution with NSS, but I dont get the option below which says Nokia Connection Cable, because yet again: no phone can be found!

Or course I tried also with Nokia Care Suite, but yet again: the laptop can't recognise the brick! Although Windows does notices I put something in the USB port and it sees the Qualcomm device.
Hard reset
Not possible, since I will get a 3 second vibration followed by 3 seconds nothing and then half-a-second vibration.
Putting phone on
If I try, it will give the 3 second start-up vibration which connects to Windows Vista (using the typical sound) shortly followed by the half-a-second vibration (and a triple-short disconnect sound on Windows).
As you guys can understand, I am in quite a bad situation now. Since the phone is bought in my home country The Netherlands and I currently live in Melbourne Australia, I hope to prevent sending it back home at any costs.
So what do you think: is this one permanently bricked, or is it still possible with a specific driver to fix this? Seems to me it's purely a communication/connection problem between my laptop and my phone, but I run out of options to try..
You could try downloading Windows Phone Support Tool from Microsoft.
Turn on your phone by pressing on and the Camera button at the same time, it should then enter flash mode (release power on buzz but keep holding the camera button). When it's in flash mode you can try and get Windows Phone Support Tool to repair the phone for you.
Thank you for your reply!
I tried it before, and this is the message I got:
Communicating with device. Please wait for Recover button to be enabled.
Support Tool version 4.8.2345.0
The tool had difficulty communicating with your device. Please check your device connection and make sure you followed the instructions above. Try recovery again and if the problem persists please contact technical support.

The problem seems to be that there is absolutely nothing is installed on my phone. Therefore, the connection with my phone fails over-and-over. Doesn't matters which program I use. I am almost sure that there is a connection fail between the computer and my phone. I tried it at some other laptops but at every laptop it says 'Qualcomm CDMA Technologies MDM'. But not a single program (NSS/NCS/Phoenix/Windows Phone Support Tool) can make an actual connection with the phone, so it must be driver related.
When I try to turn it on, it starts up but then puts itself off, like if its out of energy. It doesn't charges though. What do you think: driver related or battery related?
------------------
Extra added info: when I try to flash Rainbow os-new with NSS, I get this message:
Checking file selection...Done.
Looking for NAND disk...Not found.
Are you sure you have development Qcom loader ?

What does that means?

Things to check:
1. Is the phone connected?(Plug to the USB)
2. Is it in the correct mode?(Try to switch to OSBL mode)
3. Have you installed the Qcom loader ?(Use the Install button)
Preparing update...Done.

Does this shows a battery problem? I have had battery problems before with my phone, but I guess that when I try to flash (even with the extra add to NSS) it should ignore any battery level. Or should I screw it open, try it again and see if it will work then?
If it's finding it as an 800 that means it's finding it (it finds mine as an 800 when I've played with it too much).
When you enter flashing mode via camera button, do you not get the image of the phone connected to a PC on the phone?
I had that in the beginning, but those days are long gone.. I don't know how it happened that I don't get that back anymore. Perhaps because my phone doesn't boots itself completely, but falls out of its boot program. Nothing visible on screen
Hello,
I have a rooted Ematic EGS-102. Following some instructions to swap my internal sd with the external one (as the memory where the apps' data get downloaded to was only 500MBs), I believe I have typed something incorrectly inside the vold.fstab file, because after rebooting my tablet it's forever stuck on the logo screen. This is my first android tablet so please bear with me. The solution that comes to mind is to open the root files by some program on my PC and edit the vold.fstab file back (I even have a backed up version of it from a few weeks earlier), or even flash a new ROM. Now, the problem is, my computer cannot see my tablet when I connect it through USB. At all. Back before when the tablet was fine, I could use the USB to transfer files to and from my computer, but after I killed my tablet, my computer doesn't even make the sound which indicates that a USB device has been connected.
I have tried changing the USB cable and the port where I connect it to (never mind that the same cable and port work with other devices), to no avail. Having given up on the USB method working, I decided to follow some instructions on installing a custom ROM that has worked on EGS-004, and according to the one who posted that, would work on other variants such as EGS-102. Basically It was steps to installing the ROM from the external card through Recovery mode, which I followed thoroughly to no avail. The tablet still gets stuck on the "ematic" logo start screen.
I've noticed that in the Device Manager my tablet is displayed as "USB Device(VID_1f3a_PID_efe8)" with a yellow triangle mark indicating that it's not working properly (code 10). I tried searching that error code and trying all the solutions I found to no avail, including updating the driver (just refuses to update and keeps telling me that my driver is up to date.)
Sadly all the other methods that would have a decent shot at working (Root explorer on PC, android recovery program, even a flash EGS-004 firmware method on ematic's website) requires USB. I'm out of solutions, and unless I can get the USB to work somehow, or find out why the ROM method didn't work, my tablet would officially be dead. I'm utterly miserable that such a stupid mistake on my part ruined my tablet, and I have no way of buying another (broke student here) or returning it (out of warranty and I'm pretty sure I voided it anyway). I would absolutely appreciate any help, and thanks in advance.
Edit: It's stuck on logo screen, not a bootloop. I'm terribly sorry for this confusion, my head isn't straight right now.
Still haven't found a solution :/
Wisky 3G068i 9,7" w8.1bing->w10 fail. Error message, cannot continue. unusable.Urgent
Hey,
I got Wisky 3G068i 9,7" w8.1bing tablet yesterday.
It was reset to factory settings. After getting things going, it worked fine with win8.1 and updated itself. Then asked do I want to update to win 10 and after reading and ppl saying its better(and i dont really like win 8) I updated it throught windows own update screen.
After night of installing it, it was stuck on 95% (took hellish long time) and had error message on it "please install extrenal removable media and press ok" (its in finnish so translation might not be correct but you get the point)
I tried clicking yes, no affect. Then removed card, put it back in and it started to revert itself back to win 8.1 after saying not enough room or some error(cant remember correct anymore).
It reverted approx 8 hours then that error came again and now its stuck on it, it wont do anything.
I tried to create win10 install to micro SD with win10 media creation tool but it wont boot from it. It boots up, wisky logo is seen and then rolls loading dot for while, then flashes some screen like command screen, very fast, I cant read what its doing and the error is back.
What can I do? there must be some way to get to reinstall of windows 8.1bing or win10 but how? I dont know does tablets have bios or how to get to it, or how do even get it to boot up some install media.
Been googling another 8 hour but i just cannot find anything that would help my situation.
How can I force it to boot from microSD or do I need to get some microusb-female usb adapter for usb stick? I have a USB hub and throught it i was able to install the win10 installation to usb stick and microsd but idk does the tablet understand that hub(and read from it the usb stick)
i have years of experience with pc's but with tablets i dont really have any.
Tablet has 3 puttons: power on/off and volume up/down
Since I dont have manual, i dont know how to do any resets on it or anything and seller did not have one and maker is chinese and hasnt answered me.
I found old posts on internet saying ppl did get the win10 to install but none posted how they did it.
tablet has:
2gb ram
16gb harddrive
microSD port where I have 64Gb brand new Kingston class10(it works even it says on specs 32gb is biggest)
3.5mm port and micro HDMI port.
Please any help is useful and Im forever gracious to whomever can help me fix it! heck i even buy you a beer if possible
So i got my friends old Lumia 920 with Windows 8/8.1 installed on it but obviously it's not really used anymore and a lot of apps are already unsupported now. So i thought i'd try and install Android over the Windows OS.
Using WPInternals i flashed the phone with a .ffu file (RM-820 - i think!) that was listed under my phones specifications, used the program to flash the phone but just before it completes i get an error message saying the boot-loader wasn't unlocked properly and now the phone won't switch on, hold a charge or do anything at all. I have tried all button combinations for a soft & hard reset but the phone doesn't respond at all. I managed to get the phone connected to my desktop temporarily in Mass-Storage mode, but then the connection disappears and i can't access it.
I've seen so many posts about this problem and being able to 'flash' it back to normal or repair the issue..
can anybody recommend or explain a technique that would work?
Many thanks!
Hi,
is there any sign of reaction in the device manager, e.g. a Qualcomm_USB device or a Qualcom_COMx port?
