Hi, I believe there are lots of existing thread similar to this topic however, in my case, I really got confuse and it makes me difficult to handle since I am not really good into this kind of situation. Primarily my device is not branded and I read many tutorials but it doesn't work.
So I have this tablet from my friend and he says that the devices is already rooted when he got this one, so he went to the system folder/file and he change the settings on that particular file explorer without knowing what is that for but he never delete any files and after he restarted the device, it only shows the main logo and it went black. there is no display at all. However, when I tried to wipe and reset the device via recovery mode, it only says that the formatting was successfully done. But when I restart the device, the same thing happen.
Again, the main problem ( for me ) is this device is not a branded one, or let me say it is not international model like Samsung, HTC and other known brands. I've been digging in to this forum but most of the time, their devices seems very familiar and known like Samsung that has supported drivers and software but this one is not really known by many. So I came here to ask some help because my friend says he didn't have any backups or anything to restore this one.
I tried to use ADB sideload ( I found some sort of tutorial here ) however, signature failed. So my question is, it is possible to load a fresh Android OS on this device without clock world mode? I think the devices is not totally dead, since I can still access to recovery mode, so I expect that maybe this can be recoverable?
I only got some few details of this device for reference purposes but I don't really know if this works.
Device Name : Fabtab Quadro 8
OS Version : Android Kitkat 4.4.2

I got a Lenovo S850 from China and it came rooted from factory. I deleted apps I shouldnt and it booted up with constant security warning. I download what I thought was the correct rom and it did not install but phone would not come on. I found a rest of world rom to install that I thought was correct but after install imei's were missing and it had nvram warning in wifi. I have fixed that issue permanently but still with any sim card it says no service and a manual search fails.
Not sure if the first rom made a mess of the partitions etc but I have no idea why etc.
Just wondering if there was an expert that could connect to my pc via team viewer and take a look at it as I can connect it via adb but no idea what else to do. I think partitions are messed as in custom recovery it will not mount anything and had to adb sideload root.zip.
I will return it under warranty if I cant sort it though they may refuse to fix if they see it has a differnt rom on etc,
Anyone help?
Thanks
Simon.
Hi,
I can't find anything for your device on XDA, so you would need to ask here and hopefully someone can help. Otherwise I suggest you contact the manufacturer for original firmware and Flashing instructions...

Hi, i bough a chinese tablet, Allwiner A20 a70x with build number wing_k70-eng 4.2.2 JDQ39 20131107 test-keys.
The problem with this tablet is that since i started using it felt some suspicious the system aplication" com.android.server"
When i tried to root the tablet i started to recive annoying adsin the the taskbar, and got installed 2 applications wich was Dr. Safety and other that i cant remember its name.
Still i was focused that the system application "com.android.server" has the guilt of that.
Then i uninstalled it and the tablet got into DEMO mode.
The only way to keep using the tablet without compromise my personal information and activity t is to froze the aplication, but im not able to remove completely the root from it, and even when SuperSU is disabled, some aplications and games detects that the tablet has root enabled.
Also the tablet doesnt let me use a custom recovery, the tablet get bricked when i try it or simply doesnt load the custom recovery).
I have been searching if i was the only one with this issue and seems not many people are noticed of this troyan (or they dont get affected by it) but finally after a few months i found this article:
http://securelist.com/blog/research/35929/the-most-sophisticated-android-trojan/
The problem is that the article only show me how the troyan works but not how to delete it without affect the functions of the tablet.
So im here, to ask to the XDA people if can help me to get rid of this annoying troyan.
[Sorry for the bad english]

I've been searching for info specifically for rooting/CWM'ing/ROM'ing this phone for a couple of weeks now and this device seems to be the bastard child of the Android world. If I owned a ZTE Blade I would be fine already. I know that help for this device exists somewhere, but using the XDA search tool doesn't pull up anything. I've searched for "Supreme", "Vital", "Quantum", ZTE in general, etc, etc, and the only thing that comes up is the LG Quantum which is obviously no help at all. And it seems that none of the other Android "help" sites have any better luck with specific information for this device (it's always a "this works for most devices, but your mileage may vary" kind of thing).
Basically I broke my phone from Virgin Mobile, bought a cheap used one in good condition off of eBay, but unfortunately the new one is tied to Sprint. Doing an ADB backup/restore from one device to the other does not copy over any of the carrier information so that was no help. It appears that this info would be copied over with a Nandriod backup, but I can't do this until I install CWM. I can't use ROM Manager to flash in a CWM image because this is not a "supported" device. I've tried using fastboot but it just waits forever for the device to connect whether I have the ZTE or Google USB drivers installed. I've tried flash_image but it throws an error saying the recovery partition was not found. I've tried just about every solution I can find any hint of anywhere online and I'm at the end of my rope. The only good news is that I was at least able to root my device using KingRoot! It's everything after that which has been the problem... I'm hoping somebody here can point out a link to a GOOD source for exactly how to at least load CWM for this specific device so I can get Nandroid going. Ordinarily I wouldn't mind experimenting with building this from source myself, and I'm sorry for taking the lazy approach and asking for somebody else to do the grunt work, but I work 12-16 hours a day and just don't have the brainpower available to deal with this right now. I just want my phone back!
As a second item, I would very much like at some point to play with loading Lollipop on this device. I've found a link which on the surface seems to have good info, but then when you try to download the image they hold the data hostage and expect you to "complete these dozen offers". NO, I'm not going to give them all of my personal info, and I'm also not going to jump through their bs marketing hoops. But anyway, this is entirely secondary to getting my replacement phone up and running. The link to this info I found is:
cwm-twrp-recovery.org/2015/03/zte-vital-n9810-5511.html
Copious thanks in advance for helping me to keep my sanity!

No response in two days, thread closed.
I have a Filemate Clear X4 tablet locked in a boot loop. The issue is I have not been able to get the maker to supply a factory image to fix the thing. It is a 1.6gz RK3188 device and I can get it into recovery mode and I believe flashing it would not be an issue, but with no image, I have nothing to flash. the recovery system is stock android 4.2.2 (3e is the code it displays) and has several options to flash the device, including through adb and from a memory card. All attempt so far to break the loop have failed and likely the device has a partition issue (and likely my fault!) If anyone has this device and can get me an image, or if anyone knows of a compatible ROM, I would be very grateful!

I tried that and the "maker", Wintec, claims they do not have a copy of the factory image and the actual manufacturer, SKTelesys (Korean) refuses to give ti to them (which I doubt!) It is out of warranty and likely I have a new door stop. But thanks for the suggestions!

Hi,
I recently bought an Umi Iron and believe I have accidentally managed to soft brick it (based on what ive found on google and the forums here) I need a way to get it working again and have some ROMS (2 official ones) which are compatible for the device. The device will boot into recovery and allows restoration from an SD card, ABD Push or the cache. The cache is empty and although i have searched for how to do it from an SD card i have found no information (I've tried putting the .zip files onto the device and installing those but the device says "installation aborted"). I have a SDK which I am attempting t learn to use in order to fix the device. Any information about how to use the program/get the new ROM flashed via fastboot would be much appreciated as I have very little knowledge of what I am doing as I have never attempted to root or flash a phone. The phone comes pre rooted from the factory (I dont know if this info is relevant but I'm working on the assumption the more info i can give the better). The device entered this startup loop when i removed an app which i had accidentally installed as a system file while trying to use an app to move it to my SD card. Any information and help is much appreciated
Hi,
I can't find anything relevant on XDA for your device and issue, but perhaps the members in this thread can help..

Hi Darth,
Many thanks for your reply, since i posted this thread I have done some further research and narrowed the problem down further. The device runs android 5.1 and there is a setting in the developer settings which locks the OEM bootlocker. This is the issue i am having. Because the device has this option checked, I cannot unlock the bootloader to install a custom rom to rectify the issue as i cannot turn the device on to access these settings. I have seen many people have had this problem with devices and android 5.1 including Nexus and HTC phones. I have been unable to find a fix for this issue though so if you know of any articles which may point me in the direction that would be most helpful
Thanks again
I would say the best place to ask about that is in the thread I linked above. But if that's not helpful, you could ask here,
http://forum.xda-developers.com/showthread.php?t=2257421
Every device is different as far as if or how the bootloader can be unlocked. So you really need an answer specific to your device.
Hope it works out for you!
