So I have been trying to fix this up for a long time yet with no success :
Aigopad N10 (bought in China in 2012), tablet that used to have a description page up Aigo website - and deleted long ago in my knowledge, quite hard to find its specs online.
Runs a Cortex A9 quad-core (Samsung Exynos 4412) 1Gb of RAM , 16Go nand + sdcard slot, and runs ICS + Aigo logos & such. Currently stuck in a bootloop.
From the tablet, I can only manage to reboot into recovery that's stock ( Android system recovery <3e> ) : so only features reboot, zip from sdcard, factory reset, wipe cache, apply update from cache.
-factory reset then reboot ends up entering the same bootloop.
-Back in the days when online customer service for this device still existed, I could manage to download the original firmware :
bootloader_mmc.bin, misc, ramdisk-uboot.img, set_bootargs, utscript, ramdisk-recovery-uboot.img, userdata.img, zimage, bootloader_sd.vhd, system.img
So I tried first to make a .zip myself following the basic tutorial and signing the file using the Java tool : still pops up as signing verification failed in android recovery
Then I tried to flash system.img using livesuit (both using Ubuntu and a win7 VM just to make sure) : getting the "invalid image file" error with every image (I read that proper livesuit images are quite specific, and unsuccessfully tried to use the unpack&repack tools, further on this way)
I also discover a russian IRu model that looks exactly the same and for which the whole device, especially the motherboard description- that of course have no serial ID or whatever- matches exactly. CPU is the same, and actually by looking at pictures of the russian model, they seem to be perfectly identical besides colors & painted branding. So I could also download an alternative firmware that would definitely fit the hardware - but same problem, not a proper livesuit image or properly signed zip for the stock recovery. Russian IRU model is IRU Pad Master E9701 (with the same specs)
Also I couldn't manage to use fastboot, since I guess it does not work natively with stock recovery, tried also to adb root, adb push and indeed ends up being ask to confirm on the device (or to enable dev options in android) which I obviously can not.
So I am running out of ideas, maybe someone has one for me ?

Hello to all.
I bought recently a Tengda T94 (also being referred to as Dapeng T94).It has MTK6589 chip.
Me,the smartass,wanted to change the DPI setting of the smartphone,because Real Racing 3 lagged a little bit and thought changing it might fix the framerate.I changed it from 320 dpi to 221 with LCD modder and reboot.Then the surprise struck me,when it didnt start,it just stood on the logo and kept replaying it.I have tried with ADB commands - some works,some not.
I am with stock recovery 3e.
Has only few commands like reboot now,install update from adb,cache,sd card and wiping cache and another option for wiping data to factory settings (and two irrelevant options of restoring/backing up user data).
I tried wiping all data and cache,still bootlooping.
Tried with mediatek firmware adapter tool,but i think it cannot change the build.prop file while bootlooping (it cannot find my device when in recovery mode),because it is either in use,or in read-only mode.
Tried with android commander,but didnt know what to do there.
I downloaded rather late a CWM recovery for my phone,and also if I am not mistaken two roms - one of them is exactly like mine.
But when tried to install thru recovery adb sideload it starts and then says : restating ADBD ....... installation aborted and returns me to main recovery menu. Tried with my backed up build.prop which i have put in flashable zip file.
However,the two roms i have downloaded arent working properly.They are zip,but still adb sideload cannot read them.
And another (i dont know if it is relevant) my external sd card 16 gb default,when i put it in my old gsm to put the two roms and cwm recovery files,first windows wanted to format it and the only option was FAT 32,total of 2.87GB.What has happened to my sd card ?
Still I couldnt install from the external sd card the roms,only zip with build.prop file was listed and gave the same mistake as said above : restating ADBD ....... installation aborted.
PP: I have arrived at the conclusion that the problem is this line ro.sf.lcd_density=221,which is in build.prop file (I might be wrong).So the question is can i somehow modify the prop file or what should i do ?
And why has my sd card shortened from 14,6gb to 2.87 ?
Sorry for the long post.
Problem with T94 too
I tried to modify the build.prop file to enable the soft keys and the phone doesn't work now! stops at the android logo and I don't know how to make it work now. I re-edited the file back to its original using ADB explorers and still the same. Any help on how to recover it would be highly appreciated.

if you want the original build.prop file i have got it,
can you tell me how did you do the CWM recovery without the phone being working?
Installing CWM Recovery Tengda T94
My phone has been bricked and after really hard work I could install CWM Recovery and I'm about to try the Spanish rom, so wanted to share what I have reached to before I forget.
----Do at you own risk-----
-My phone was in a boot loop and USB debugging was previously activated before it bricked
-I installed all the necessary drivers, USB_VCOM_Drivers (Available here: http://goo.im/devs/C3C0/THLW8/tools/USB_VCOM_drivers.zip)
I created the scatter file/map using MTK droid tool, and used the CWM Recovery of the Spanish Rom at this link:
http://www.movilesdualsim.com/foro/threads/42700-ROM-Custom-ROM-T94-v1-0b
I'm going to upload the scatter file and the CWMrecoveryT94.img, download this sp flash tool for quad core scatter files
http://www.4shared.com/zip/kf__h7u-/sp_flash_tool_zopomobileshop_q.html?cau2=403tNull
Switch off your phone, open SP Flash Tool Quad Core that you downloaded, choose the scatter file available here, double click recovery and choose the CWMrecoveryT94.img available here and press "Download" press yes for the message that appears and connect your phone, it will confirm the success by a green big circle message.
I will update my further proceeding.
Tengda T94 GPS never works
Does anyone have any idea about fixing the GPS problem? I watched a video in youtube in spanish who showed a working fast GPS but I don't understand what he says but he showed in the description that he added a copper foil piece to the GPS antenna, if anyone had luck fixing it please share.
Here is the video:

Sal all,
I cannot find firmware for this tablet. It's a 7inch, dual camera, atm7029 quad core cpu, that doesn't start, but i can write firmware with Actions Pad Product Tool.
The only available firmwares for this type of cpu (atm7029) i was able to find, were from Ainol tablets, but these are not good.(only lights start 1sec)
Can someone help ?
10x in advance !
Hi! There is a similar device firmware from (Russian): (yadi.sk/d/Wku6HWTxKkaKa)
But WiFi and camera other.
System image
Here is the image of the system partition. Dumped with ADB from a working tablet. (512MB)
(mediafire.com/download/roc8870rirvt3hw/actc_system.img)
And this is the image of the recovery partition: (48MB)
(mediafire.com/download/fd30kaio8xb490j/acta_recovery.img)
If you want to see what's inside the images, mount the image in Linux, or use Linux Reader if you're using Windows.
How to use the actc_system.img and acta_recovery.img
Hi, I'm an android newbie needing help. I found this thread while searching for how to deal with a bootlooping Orion TAB-700qc tablet belonging to a friend.
Apparently my friend tried to update the tablet with the wrong update (I'm not really sure what he did), but it went into a bootloop -- it will not get past the "android" screen. I found how to go into the Recovery menu but nothing there would fix the problem. I have downloaded the actc_system.img and acta_recovery.img discussed in this thread, but I need step-by-step instructions for how to use them to get the tablet working again.
Can someone please direct me to instructions that I as a newbie will understand? I have worked a lot with pc's but I have almost no experience with androids.
Thanks,
cmNhu
Vodafone Smart tab 3 10 (aka Lenovo S6000H) and the "Please press button to set ..."
I have got a Vodafone Smart tab 3 10 (the one with the 10 inch display). It should be the same as Lenovo S6000H (as the Vodafone Smart Tab 3 7 is the same as Lenovo A3000H). It has 1gb ram and 16gb memory.
I received it quite bricked; I mean, when it was gave me (so before any action done by me) I turned it ON and it showed the Android logo and then it rebooted continuosly (loop). The person who gave it to me told me he tried to restore default configuration (the tablet was ok) with low battery. So low that during the restore action it switched OFF... bricked. Honestly, I don't know if this is true or of he tried to flash a rom (maybe a wrong rom).
Anyway, I flashed a standard Lenovo rom: now it doesn't show anymore the Android logo but the Lenovo label and it doesn't reboot anymore (till here is ok)... The fact it's that after showing the Lenovo label it shows the message "Please press button to set the Country Code" and I can't do anything (because even if I press on the display I haven't any result). I can only switch it OFF holding the power button.
I tried every stamdard rom placed here
http://lenovo-forums.ru/forum/182-lenovo-ideatab-s6000-официальные-прошивки/
but without amy success: same results.
- Any suggestion?
- And if i flash also the fac.img can I have something different (all rom I have flashed haven't the fac.img checked)?
- In recovery mode I can't do anything die to the fact there isn't any item that can be selected
Attached logs extracted during the latest flash
Many thanks
Hi, any help on this?
Hello my friend! I've been out of the MTK world a bit, but my daughter's A1000 is giving me fits, so I may be back! It too has a battery problem. It will not charge after the battery drains to a certain amount. Lenovo has a software patch -- but this POS A1000 won't go into programming mode most of the time. (I've also gone to Win7 from XP for flashing, it seems I knew how to work with the MTK drivers better in XP)

I think I might be able to help. I suspect the difference between the Lenovo and the Vodafone is the partitioning. What I've found is my old Vodafone Tab 2 (and some other A2107A variants) has a FAC partition and others don't. This is the partition that has the code to select a Country Code. So you have one more partition on some OEM versions, and that partition is in the middle so it shifts down others. This causing your Country Code Selection to never get written properly, and loop.
So... the only way I was able to flash in those situations -- do a FORMAT in SPFT with a scatter that matched the new ROM. The FORMAT will re-apply the scatter partitioning to the device. I also had to re-write the bootloader code which I think is just a checkbox in the FORMAT screen to format WHOLE.
Caution -- Flashing a A2107A-H generic to a A2107A-F, I was able to use the FM Radio... which Lenovo claimed the -F didn't have. But... The -F with the -H firmware was VERY jittery. Just a word of caution about mixing ROMs with different devices.
I can look deeper into this if needed over the weekend.

Many thanks friends!
To be clear, I'm trying to flash the standard rom only because I can't find any rom related to Vodafone Smart Tab 3 10.
For me having the Vodafone rom or the standard one is the same.
Question:
1) Example, I have the standard rom related to Vodafone Smart Tab 3 7 (it should be the little brother of the 10 inch) that I've dumped when I had it... can I flash it to the 10 inch...?
2) In all tests I've done using SPFlashTool I have used the DOWNLOAD option (not the "firmware->upgrade" OR the "format" function), without checking the "DA DL ALL WITH CHECK" and without checking the FAC.img (infact when I load the scatter file provided with the rom this .img isn't checked)
I apreciate your help if you can give a look
Many thanks

You are going to have bad luck trying to use a ROM even for a slightly different model.
To add or remove or resize a partition (or you might call it a block) in the flash, you have to use the Format function. This is scary for sure though.
Side note:
Many people have broken their tablets and phones trying to resize partitions with tools, because the tool fixes exactly one model/variant. So if you use some slightly different model, it goes and tweaks things incorrectly.
Hi everyone,
A couple of days I posted in XDA Assist and was asked to seek help here. Therefore, I'm posting my original post here, along with some updates at the end.
Original Post:
#####################
I've got a reasonably unknown Tablet PC.. Here are the specs and miscellaneous information;
Name: Ainol Numy 3G P97
Internal Memory: 16GB
RAM: 1GB
GPU: Mali-400 MP
SoC: MediaTek MT8382 ARM Cortex A7 @ 1.3Ghz (Quad Core)
OS: Android Jellybean 4.2.2 (I'm pretty sure it's a Custom ROM)
Kernel Version: 3.4.5
Build Number: Numy_3G_P97_V1_2014090215
Custom Build Version: 1.19_20140822
Root Access: No (I never tried to root the device, never had a reason to do so)
I've been searching around for ways to upgrade the OS from Jellybean to Lollipop or higher. I've searched extensively within XDA Developers' various forums, but there doesn't seem to be any post in relation with my device.
I took to the internet and found some websites offering Flash Tools, Firmware (nothing above KitKat, or so it seems) and Android Studio. I've tried (in vain) to go through some tutorials on YouTube, but haven't come across anyone who's done anything with this particular device.
However, I have a rough idea rattling around in my head of what needs to be done, but I just need guidance from the Developers here to tell me how to get about doing it.
I have the following software downloaded;
1. MediaTek USB Drivers and Flash tools
2. SP Flash Tool v5.1620
3. Official Android Jellybean 4.2.2 System Image for the device
4. Android Lollipop 5.0 System Image (the site I downloaded it from says the Firmware is for a different tablet pc, but with the same specs as my device)
5. Android Studio (latest version, direct download from Google) - I read in some sites that Android Studio would help a lot to install a Custom ROM into any Android device, hence the download.
I'd greatly appreciate anyone helping me out in this endeavor. I'd like to install Lollipop (at least) on my Tablet PC, in order to gain some functionality as well as improved performance (hopefully!), as the current Jellybean OS is terribly laggy. I've seen other Tablet PC's with lesser specs running Lollipop smoothly, so I'm hopeful that there might be a silver lining to an otherwise very dark and sinister looking thunderstorm.
#####################
End Post
Updates:
While waiting, I've tried a few things. I downloaded the following;
1. Android SDK Tools with Platform Tools
2. Android Lollipop system images x 2 (.img file format) (similar specs to my Tablet PC)
3. Android Lollipop system image x 1 (.zip file format) (similar specs to my Tablet PC)
4. Android KitKat system image x 1 (supposedly the original and official KitKat OS for my Tablet PC)
5. Kingo Root app (Windows version)
Here's what I tried:
I tried using ADB to sideload a Lollipop system image (.zip file format) through a custom recovery already installed on my Tablet PC. Each time I tried, the installation would just stop with "Installation aborted". No matter what I did, I couldn't get it to work.
Next, I tried to "update" the current OS (Jellybean 4.2.2) to KitKat using the "official update" I found on the net, for my Tablet PC. I used SP Flash Tools to try and load the file, but that didn't pan out, as there was something corrupted in the Scatter file. Each time I tried to load the Scatter file, I'd get the error message that it was corrupted. Didn't know what else to do.
Following that, I read some articles where rooting the device in question was suggested, so I searched around for a bit, found the Kingo Root app, used it and rooted my device. Then, I tried using ADB again, this time using a more traditional method of custom ROM installation. But once I got to the Fastboot commands, I couldn't get any further. My device did boot up in Fastboot mode, but I got lost after that.
As of yet, my device is still running Jellybean 4.2.2. I've refurbished it by doing a master reset, but I'd really like to get Lollipop in, if it's possible. Any help would be much appreciated.
Thanks!
Serious help needed please!
I really need help, people, on this issue! Isn't there some kind soul who will respond??
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.
