Hello everyone,
I have received a HOLDS NJ-N81S Spreadtrum SC6820 based android phone ( a Samsung Galaxy S4 Clone). During a failed root attempt via VROOT software, the phone no longer boots. I did howerver before even using VROOT make a copy of the local files via ftp, I do not have a real backup ROM etc.
I have been stiching FDL1/2 files and nvitem files from various other chinese phones to make a frankenstein ROM for my phone and have succeeded somewhat. The phone now boots correctly and I have sound and LCD screen is no longer grabbled.
My main roadblock is the touchscreen panel, I do not have the correct drivers for driving the panel, my original kernel modules are not compatible with my stiched ROM. I'm in need of help if anyone is able to assist me, I've attached below the original peripheral drivers before the failed VROOT app
Original drivers: www dropbox com / s / moj2upchd2x6xos / Spec_NJ-N81s-drivers.rar
the ko versions are: 2.6.35.7 mod_unload ARMv7
the version I need is:2.6.35.7 preempt mod_unload ARMv7
the touchpanel driver is the mxc622x.ko which is needed in order for the ft5206_ts.ko to work, flashing the ft5206_fw.bin to the chip I think isn't necessary as the focaltech panel controller chip wasn't touched.
Hello everyone, I have made some progress on the phone since I last posted the problem.
As I did not have a ROM backup of the phone before proceeding to ROOT it, I had to scavange the kernel modules to handle the display, touch, sound, and the modem around the net. I have succeeded in getting the phone to properly boot and touch is working. My first problem was the screen being flipped upside down, but I got around the problem by patching the build.prop to rotate 180.
The biggest problem I have right now is that I get a corrupt display everytime the phone wakes up from standby, I press the power button and the phone goes to standby fine, but I don't see an image when I wake i up again, I can hear the sound working, the touch still works etc. I need help fixing the problem I don't know if it's the MALI gfx that has trouble waking up or something else is at play here.

I now know the Allwinner A13 is a stripped down version of the Allwinner A10, to be clearer the specifications of my Tablet (from UniFlash and AnTuTu Benchmark) are as follows:
Manufacturer: None
Brand: softwinners
CPU hardware: sun5i
CPU model: ARMv7 Processor (VFPv3, NEON)
CPU frequency: 60.0 ~ 1008.0 MHz
Screen resolution: 800 x 444
GPU vendor: Mali-400 MP
GPU version (OpenGL): OpenGL ES 2.0
RAM size: 512 MB DDR2 RAM
Knowing this, I used UniFlash to make a backup of the firmware bt after using UniFlash to try and load a CM9 Rom on to the Tablet, the Tablet died. After alot of googling I discovered AllWinner based chipsets use Live Suite (sometimes called LiveSuit) to flash firmwares on to the device.
To Flash firmware on to the device you need to follow the attached instructions ((http://dragondevs.com/viewtopic.php?f=159&t=390):
Download LiveSuite (http://www.softpedia.com/get/System/System-Miscellaneous/Live-Suit-Pack.shtml)
Install Live Suite
Start Live Suite
Select the Live Suite image file (folder icon
Turn device off (to be sure hold power button for 12 - 20 seconds)
Hold "Volume Up" button down
Connect the device to your PC (while still holding "Volume Up" down)
Start pressing the power button (you may need to do this once a second for 5/6 seconds)
If you haven't installed windows will ask to install a driver for a device (Dive Id will be something like Vf73465789123465435_Id, if the device is in the right mode, A13-MID, ADB-Interface indicates the tablet has connected in anouther mode).
Once this has finished LiveSuite will detect the device and a wizard will flash the firmware for you.
I have found a working firmware which according to AnTuTU Benchmark gives my tablet a rating of 3047 (see firmware section), this is on the higher end of reported A13-MID tablets
I have found out how to install CWM on to the device via SaussageMod (http://www.slatedroid.com/topic/29916-scriptmod-for-allwinner-a1x-platforms/). This solution is untested, further more it may be unnessary futher investigation has shown this website (https://www.miniand.com/forums/forums/2/topics/73) has developed a way of create Live Suite images. This is simplier than installing clockworkmod recovery,
I tried to load the following images on to my tablet and failed completely: http://forum.xda-developers.com/showthread.php?p=31043317 It didn't work and forced me to do a firmware refresh.
My other step for the day was to create Ubuntu 10.10 installation then I began following this guide to construct an Xperia Play CM9 Rom/Kernel. once I have created a working ROM (I own an Xperia Play). I'm hoping to be able to modify the kernel to include the relevent A13 drivers, but one step at a time.
TODO
Create Ubuntu Partition
Follow Xperia Play CM9 Rom/Kernel Guide and create working rom (test on my Xperia Play)
Download CT repository (https://github.com/christiantroy) and compare with Xperia Play CM9 rom
Find the relevent drivers from https://github.com/amery/linux-allwinner leaked source
Retrieve offical MALI 400 MP drivers (parts of it have been released) compare with leaked source
Use UniFlash backup of original Rom along with LiveSuite image creation to try and restore original firmware (see If I understand it properly)
Examine Build.prop find out why original firmware displayed ina phone layout and new one is in tablet mode (potentially reference CM supported Tablets).
Attempt to compile a A13 (Sun5i) based rom
Create a google code page to hold all of these thoughts properly.
Left blank will include rom/firmwares here for future reference

I have the same tablet and it would be very cool if you succeeded in your attempt to create a CM9 rom for it. I tried ROM made by Tragidy from this thread but there is a problem with touchscreen driver, ROM booted successfully but I could not even unlock the screen cause touchscreen did not work. I finaly flashed rom DCPAD2121.zip using livesuite which I belive is the original ROM that came with tablet and it worked.
I installed clockwordmod using sausagemod successfully, but there is a big problem - no hardware "back" key and only volume up works.
novo7tools.apk works OK for reboot, reboot to recovery or shutdown.
syncing
Thanks, it's slow going at the moment, I only spending ~1 hour each day on it and at the moment trying to sync the CM9 source is painful (it keeps timing out, due to "remote side corruption").
I figure I would start there as all the firmware images I can find are ICS roms (meaning the drivers must be ICS).
Hi, I have the same tablet but I cannot find the firwmare DCPAD2121.zip
Could you upload it please? From dropbox has been deleted

I tried that ROM, on my tablet after flashing the ROM it got stuck in a boot loop. It might be an idea to steal the config he created. The ROM is pre CM9 release. The A10 Flash kitchen software seems to work. I was hoping on producing a complete Live Suit image that people could flash (figuring our what CT has done on the A10 took a while).
Still having fun trying to sync the repositories, given up on trying to use a Debian VM, I'll will install full Ubuntu on a drive tomorrow, hopefully that will help fix things. It doesn't help most of the guides I can find are out of date and I keep having to make corrections.
I've also uploading all firmware I can find to my dropbox (at 200mb each they will take a while), I won't with tools simply because others ask you not too.
The Dropbox firmware was out of date when I tried to download it sun5i_android_a13-pfdq88_en_D06 firmware worked well for me, the firmwares are located at: https://www.dropbox.com/sh/bzjt7mzuftwz79f/nt7mRMPDj1
Cyanogenmod 9 in not working for you. Did you made data and cache wipe? Can you send me logcat and dmesg output?
You can`t steal my config, you have to remember about credits, and other stuff.
Creating a wiki is useless, there is already wiki for allwinner products, so better update info on it.
Github is better than google code to keep sources.
Using Livesuit=Windows, I hate dual booting just for flashing, Clockwork Recovery or modified SDcard with uboot is better solution.
Current kernel is not working well, with sun5i.
Using VM is stupid, because building rom takes a lot of time on quad core pc without it.

I wiped the caches I couldn't send a logcat or dmesg as the device simply boot looped.
I've been providing links to threads whenever I come across others work, I'm new to android rom development for me this is a research effort which will hopefully produce something cool for my £50 tablet. Basically my day job has switched to developing UI's and I am looking for something new to learn (instead of why is Vaadin, Guice, SWT, Javascript, etc... is putting that button there).
Said dev career has also made me hate Git with a passion (not as bad as perforce but still) since Git integrates poorly with Visual Studio and Eclipse and you end up getting everyone overwriting each others changes. The idea of google code is simply because it makes a good platform for projects and you can use things like git with it. I didn't know about an Allwinner wiki, with all of my Googling I haven't come across it, where is it?
I don't care about build times I'm just researching, alas Debian has caused me enough problems so I've installed ubuntu on to a old disk I had lying around. Considering I've just tried to install Ubuntu via a Net install CD and it has screwed up the GRUB installation (nicely taking out my windows partition as well) can you blame me?
The reason for nabbing the config (and the Xperia Play and Christian Troys) is to understand how they work. Over the years I've found most Open Source software documentation is poor unless you have a set level of knowledge about it already.
Lastly I like automation, I want things to just work. Livesuit does that since I am normally a windows user, I as hoping in the distant future once I understand the build process to set up a Jenkins server to do it and create the whole lot automatically (via the Allwinner flash kitchen). In the even longer term I would like to update FlashTool to do what LiveSuit does. In the near term (next couple of months) I just want to be able to build a CM9 image.
All android and kernel source are keep on git, so changing it is stupid.
This is allwinner wiki: http://rhombus-tech.net/allwinner_a10 you can also update http://elinux.org/Hack_A10_devices
Everyone use CWM and it's standard for unofficial firmware/ROMS

Mind sharing your repo ?
Trying 4.1.2
Hi all,
So I've tried compiling from 4.1.2 source for my A13 Emgeton Consul 3
It boots up and gets to the CM10 boot animation but it doesn't get past it.
I can adb at first boot until adb stops.
logcat from boot attempt:

My build.prop:
http://pastebin.com/Ap9M1tjW
Any pointers as to why it doesn't get past the boot animation?
Hello guys! I know it's not he proper place here to pose my question, but I am definitely at loss!
Do you happen to know if there is a way of rooting this tablet? And if so, does everything work properly after that?

I've gone a bit quiet on the development front, setting up a file/media server & samba domain server to power my home network is eating up my time.
My dropbox contains every image I could find for the tablet, as mentioned previously you can root the device using saussage mod, although my device and every one of those images is already rooted. You can prove this by installing super user.
Sassage mod's clockworkmod recovery doesn't work for me and I was looking at the backup tool in order to generate my own one. If you are aimed at any development, let me know and I will update the main thread
Many have said that they have "lost" "forget" to take backup from original rom. So, i'd like to have backup from my original to go back if/when something goes wrong. How do i do that? What software i need. Do i need to root?
This is from my info sheet:

I just installed OpenVPN installer and installed the OpenVPN binary in the system/xbin
After that I tried to connect to my university's VPN but when it tried to connect, the tablet lost wifi connection and ever since it doesnt connect to any available wifi network!! I manually deleted the OpenVPN binary, but problem remains!
Do you know where could I find the stock ROM for this tablet in order to re-flash it?
Do you have any other proposals? Anything will help!
Thank you very much!!
Don't know if I should've asked somewhere else but here it goes...
The device I have is a K-Free (or K-Phone) K480 aka Karbonn Titanium S25 Klick (it has another name in the store I bought it jeez) and what I'm specifically trying to do is to boot a kernel from another phone, almost exactly the same model Gigabyte GSmart Mika M3. Both phones run on the MT6582 platform.
Both devices are nearly identical, with the exception of the front facing camera where on the GSmart it is 8MP and on mine it is 5MP (the only difference in H/W mind you) and I even have the case for it on my phone. The point is - the hardware could be considered the same thing. Then I took a look at the software side of things...
Guess what - everything's almost the same as well, down to the partition layout (scatter files identical), littlekernel (uboot) works on my phone and yet I can't boot the boot.img of it or even the OS (haven't tried too hard on copying system.img, it should've worked with the ROM I have) so the only conclusion I can make is that the preloader needs to be flashed as well which is the most scary part.
Comparing the two preloaders from each phone, the one I have is newer than the one from the GSmart and I know why exactly - the dude in the store flashed my phone since it was a "new" model lol. The OEM provided them with software for Karbonn Titanium S25 (v1.7). Other than the date, there are still some differences - at the large chunk at the beginning it is the same, some stuff is moved around and most of all the final portion is different and I assume that's for the kernel side of things, but I could be wrong. So in conclusion, a large part of it is similar as well.
The reason why I make this fuss about is because Gigabyte seems to update their devices more often for one and the second reason would be simply exploring the possibilities of what I can and can't do with my phone and finally, the third reason would be ultimately, Gigabyte provided me with kernel sources for their Mika M3 and yet nobody from K-Free or Karbonn have responded so I have to get the stock GSmart kernel running on my device anyway and I know it's possible.
I need to know one thing for sure - would this work? The only way to find out is to flash it and I am a bit skeptical to try it out. Unless there's a safe escape route (no testpoints or anything, it's under warranty), I really don't know if I'm going to try it at all. At least, if anybody knows if the device will load some preloader or USB VCOM mode if it fails, please let me know.
EDIT: Just to let you know, holding Vol Down while plugged in without battery loads the meta mode, so it may work after all. I ask people who are familiar with MTK devices to confirm if MT6582 after failed preloader will continue doing that.
EDIT2: I was a bit impatient, but hey, flashing the preloader worked! lol Now onto turning the phone into a Mika M3 completely...
EDIT3: OK nevermind it seems I have answered my questions myself. To everyone who owns this device: you can flash Mika M3 software on it. Everything works just fine.
I found this bricked tablet, it's a generic chinese 7 inch tablet, it has the MTK8382 processor, single SIM, but I can't figure out anything else about it. Is there any kind of universal rom for these things? I tried to install some roms I found online for models with a similar shape but I ended up bricking it, now it just display lines on the display or a white screen when I turn it on, nothing else works. Should I just throw it away?
It's this generic model that can be found on alibaba if you want to buy in bulk and start your awful tablet company: http://www.alibaba.com/product-detail/MTK8382-7-inch-alps-tablet-pc_60273334448.html
I managed to resuscitate it using a rom meant for a device called IKON 7 Tablet, also known as Royqueen MR706. I had flashed at least 20 roms for similar devices before I found this one. It works 100%, even the camera and the FM radio, so it must mean it's a clone of a clone of a clone with the same source hardware from the same crappy chinese factory. This rom is pretty decent too, moderately fast and only has a few crappy games preinstalled, no malware or weird stuff. It even comes with the google apps (still not giving it my google account), flash player, and office suite.
This is the info from MTK Droid Tools. Any other rom I can get for this device to make it a bit more useful?
Also, it seems like I lost the original IMEI of this device. Is there any way to recover it or give it a working IMEI?
I have the same tablet too!

Hi! I have the same tablet and in my case this ROM not worked.
My tablet is: Mediatek MT8312v. Was bricked, and I tried flash with ROM royqueen MR706D by rp_yonex (maybe you saw it out there) but not revived correctly... showed a IKON logo when it start but the display and touch function failed, the screen is misaligned or is seen as half, i don´t know how say, just not functioned correctly.
But i think that i'm not very away from solution.
Even though the screen does not work very well, I could get this data in the "settings/ about tablet" :
Model number: IK-TPC783
Android version: 4.2.2
Baseband version: MOLY.WR8.W1315.MD.WG.MP.V18, 2013/11/29 20:10
Buil number: MT83x2_MR706_MR7063L1C2W1.2014031418
Custom build version: 1.19_20140125
Hardware info: MT8312
Please help!
I'm having an issue with a VERY similar device... It's an MR706, with zero markings indicating brand/manufacturer... The motherboard appears to be model K20-MB-V1.0 and there's a chip (not sure WHICH chip) with a brand called FORESEE on it. Anyway - I attempted to update the firmware using that royqueen scatter, and now the thing won't boot at all. Held the reset button, held all buttons, plugged in (it was at 96% battery before I flashed it) - nothing. Wondering if it's totally bricked or if there's some magic that someone can teach me...

You must be sure the exact model to the chip (the big one usually). In my case it's "MediaTek ARM MT8312v". You can search a compatible ROM to flash with the SP Flash Tools.
Or check if this help (mytabletguru.com/how-to-find-chinese-tablet-firmware)

While I'm a fairly seasoned technician, I'll fully/freely admit to this being the first Android tablet I've taken apart. Here's a picture of the innards - help?

PLEASE HELP ME
I just noticed these new posts in my thread. Unfortunately I'm not able to help any of you because I literally fixed mine via trial and error. Like I said I kept flashing rom after rom until one worked. I bricked it in several ways before getting the right rom, it had all kinds of issues from not booting at all, showing a boot logo and then bootlooping, showing lines on the screen, and so on. I found it by googling for devices with similar hardware.
But honestly, it wasn't worth it to fix this p.o.s.
If you have a similar device you're better off getting rid of it and buying a new one.
Pls anybody apparently i have some adwares and trojans into my system apps like smsmanager, rstech_knile etc all system apps cant be disabled or removed, only flashing rom is option, but i cant find any rom for this model pls is any other simmilar model that i can use maybe there is some tablet that have same rom model or something like that. Thanks in advance for help.
Hi everyone,
I also have this device and I'm willing to report my case because I'm also in search of the proper ROM for this device which I recently messed up (hardbricked) by flashing wrong ROM.
I was recently struggling to remove the malware and viruses that were installed by some of the in-built applications coming with this device. Tablet became very unusable, especially when it was using any kind of internet connection which was exploited by malware applications showing me tons of the ads and pop-up windows on screen.
It was impossible to download and install any application using Google Play store because tablet end in glitches running malware software in background thus occupying nearly all available memory. The only thing that would help for a while was rebooting it again and disabling any kind of internet connection, uninstalling and disabling malware and infected apps.
This would release some RAM but not for long. After few minutes tablet gets unusable and sometimes reboots itself. Each reboot would refresh and re-install removed malware software and same story happens again.
Then I came to idea to try to wipe all data using recovery mode, but even this didn't help. System was infected in its core.
Then I tried installing KingRoot, Stubborn Trojan killer, Malwarebytes apps using Wondershare MobileGO PC application for managing Android devices over USB. I was able to install manually downloaded .apk files of these apps to the tablet. But running this applications or trying to regain ROOT status would reboot tablet again and again giving me no other chance except to try to flash its ROM.
The main mistake I've made is not making any kind of current device ROM backup using MTK droid tool or any other kind of tool. Because I'm not too much in Android world, I though I could flash it (using SP Flash tool) with "similar" ROM content coming from different device but I was VERY VERY wrong. Doing flash with wrong ROM instead of my device ROM (which I didn't backup), I've made my tablet hardbricked, infact it is 99,99% dead because it doesn't want to turn on and charge anymore!
Please don't mess up Your device like I did with mine!!! It turns out that you must have 100% compatible ROM image with your device!!! To be 100% sure about Your device specs, You must previously read all information like firmware, motherboard, CPU, etc... using any kind of software (if your device is still alive) OR open it and see what's under the hood of device and make notes about it. For HOW-TO flash Android device research the Youtube/forums/blogs/google...
Anyway, there might be some hope if someone notices posts in this thread. My tablet can be decteded on PC once it gets connected over USB cable. In Win7 (32bit), after installing MediaTek USB VCOM drivers, it is currently seen on MTK USB Port (COM7). But once connected on PC over USB cable, it gets connected and reconnected on every few seconds. I've read somewhere on forum that this is expected case, but not totally sure. I'm still wondering why tablet is not detected under DA USB VCOM Port or Preloader USB VCOM Port as expected for flashing purposes in SP Flash tool.
I've already tried to use few ROMs and flashed my device but I couldn't find proper ROM yet. XWAVE brand cannot be found among few popular Android ROM websites.
After hours of searching I've found a thread about XWAVE XPAD G3 701 on some Vietnamese forum. The link is (message me)
After registering on this forum, forum revealed a link to the rar file containg ROM backup for this device. I've tried to flash my device with this ROM using SP Flash tool but it was still unsuccessful.
No matter how much I tried, I keep getting these 2 error codes (google them), 4032 and/or 1042. I didn't know if I'm doing something wrong or this ROM seems incompatible to my device version, but flash process is stuck at first stage in SP Flash Tool "DOWNLOAD DA 100%" (red bar).
Then I decided to look under the hood of my tablet and I found that my tablet's firmware is not the same as one in the ROM I've downloaded. This is probably why I can't properly flash this tablet (or I'm still doing something wrong or my tablet is 100% dead). Since this tablet has non removable battery, I've tried to keep pressing Volume - (and other key combinations) while connecting device to PC and before flashing starts.
Anyway, If anyone can make/share 100% compatible ROM image to my device specs for me/other people to try to flash it, that would be great.
My devices specs under the hood are NEXT :
**********************************************

Well here I have a wonderful problem, I have two devices, according to the working one and the cpu z:
4x ARM cortex A9 @1.42 ghz
revision r3p0
Rockchip RK3066
Model rk3188
Manufacturer Zowee
Android version 4.4.2
bootloader unknown
java vm Dalvik 1.6.0
kernel 3.0.36+ (eng.candy.20150403.110733)
The device that has the problem is the exact same model and all, however, after plugging it to the AC current, it tries to boot up but enters into recovery mode, none of the options work at all, looking into youtube I found out that I can extract the firmware, so far so good, but, I can't use that method because RKROMDUMPER and RKAndroid_v1.29 need the tablet to be plugged and there is the problem, the faulty tablet does not load in that mode while plugged to the computer.
So I was left with the option of getting into recovery mode and attempt to update from external storage, so far the only "Firmware" or "ROM" I've got is the one I extracted from the working tablet, I have, backup.img, boot.img, kernel.img and so on, the biggest one is the system.img which is near 6GB size.
I really don't know how to proceed from this point, do I have anything usable with those .img files? I have tried downloading a 4.4 Android rom, the recovery tried to load the files contained in the zip folder yet the loader showed messages such as, bad footer, or invalid image or always a denial message of whatever sort you may imagine.
So, I am stuck, reading further more I discovered that there are other methods or even other roms that can be loaded, but the Zowee guys have near to nothing to work with.
Could you please help me with this? Are the .img parts usable or in some way "joinable" like merge them into a single file or directory?
The device was not rooted, so I am left with only the chance of fresh installing from sd card and nothing else.
Thanks in advance.
