Please help a noob: A13 tablet. - Android Q&A, Help & Troubleshooting

Hi everyone,
I'm freshly registered and totally ignorant in all Android and tablets stuff. Also please excuse my english, and if I haven't posted in the right place.
I recently bought this tablet [MID tablet, GPU MALI 400, 512 MB RAM, Android 4.0.4, CPU: Boxchip A13 Cortex A8 1.2GHz], I wanted a light portable device and for the price it seemed like an excellent offer.
At first I was pleased but then found the device too slow, hard to handle, etc (I couldn't watch videos that required Flash 9.0). So I decided to upgrade the OS from Android 4.0.4 to Cyanmogen 9.0. I used PhoenixCard 3.06 on a 16Gb SD. The burn was succefull. I plugged then the SD into the tablet, it flashed, the green bar was fully filled and at the very last end it showed "sprite update error: failed to open part file [@". Not knowing what was the issue I took back the SD, turned on the tablet then at the little Android logo, it froze, and the logo splashed lol. No way to turn the tablet on again. I'm downloading right now the firmware ROM and hope to make a succefull flash.
Is there anything I might do to get it back working if this doesn't?
Thanks.

probably not. most of those chineese allwinner tablets are lacking built in recovery, so hard reset to factory settings is probably not an option.
flashing stock rom is the way to go.

[Q] Sanei N77 can I have the CM on it?

Hi there freaks,
I'm an owner of this chineses piece of... art. And um it's kinda laggy so I decided to use the Greenify and SDMaid apps to get it to better shape. After spending few days in a row trying to find a way to get it rooted, I've found this forum and the thread where they presented a way to root most of the tablets on the market. Well I was scared cause I did not find a single tip about how to turn back the changes (in case I'll brick it-my wife would kill me;p), any way I decided to give it a shot and it worked. I keep getting info that root was not found sometimes but I need to reboot it and start over and in fact it seems to be rooted.... anyway I need to speed it up a bit more.
Can I install the CyanogenMod on it? And I can - which partical version will work fine with my tablet? I've found CM roms for Sanei N10, Sanei N83, N90 etc etc but nothing for N77. I can't even compare the roms cause I have no idea what is the exact hardware installed in it and don't know any way to find out. I could look for a specific CM rom that has drivers to my device but don't know what's installed in it. I know that there is probably no way to get back to the original Android 4.0.3 ICS which I have installed right now.
All I can provide you with is the model name and basic info like:
Device name: Sanei N77 Elite
CPU: Allwinner A13 1.5GHz
GPU: Mali -400MP
RAM: 512 DDR2
Int.Memory: 8GB
Display: IPS WVGA 800x480px, TFT
Wifi: 802.11bgn
No 3G support - but they say I can have it working with these modems: E1916, ZTE AC2736, HUAWEI E1750, HUAWEI EC122, HUAWEI EM770W
Thank You for Your attention and possible help
---> anyone?
I have this piece of art as well.
After a lot of hassle and searching around I managed to boot CM10 on it. (just need a few patches to make it fully working, was too lazy at first)
Basically all you need is this:
http://forum.xda-developers.com/showthread.php?t=1886460 - ROOT, select old special or new standart root, whatever works (depends on firmware installed)
http://forum.xda-developers.com/showthread.php?t=2189640 CWM based recovery
http://forum.xda-developers.com/showthread.php?t=2343531 CM10 ROM for Allwinner A13 Tablets + patches
BTW, if you boot into recovery, format system and then reboot tablet without any ROM flashing, it will become bricked as there is no way entering recovery mode without adb (as far as I know) on this piece of art. In this case you would have to flash one of the stock firmwares (download flashing package from there) and then do everything all over again (root+install cwm)
EDIT: Since my touchscreen is not working now (haven't flashed patch for it in the first place) and as it turned out USB debugging in this CM10 build is off by default (so I don't have access to ADB nor CWM), I need now to do this whole process all over again, lol.
EDIT2: It turns out there is not patch for ft5x_ts (touchscreen included), gonna pull it from stock fw and make flashable zip, will upload it here as well.
Ok I found it there http://forum.xda-developers.com/showthread.php?t=2189569

[Q] Chinese Android device bricked? (MTK6582)

I bought a few weeks ago a Star i6, basically a chinese android phone with quad core MTK6582 processor and Kit Kat version of the OS. If you follow this kind of devices, you should know that it's a pain in the ass to root.
Still I gave it a go using the only method that people claim it actually works (the one with the scatter file) but something went wrong in the process, either when extracting the file or when transfering the modified one back on the device. As a result the device is stuck at the boot screen, showing the logo and restarting after a few again.
Now if it was my old device (an Xperia Play which still goes strong I might add), I wouldn't be worried but so far this device was just a pain in the ass. Does anyone know how to unstuck the device, or am I stuck now with a brand new brick? I can access the recovery mode of the device but cleaning the cache and doing a factory reset didn't do anything.
Supposedly I can install an update through this menu, but I'm not sure what files I should use.

Installing custom recovery mode

Hi. Just found me a cheap replacement tablet after my previous one bricked a few weeks ago(I had rooted it, it was working better than ever for 4-5 days and suddenly shut itself down and restarted one day and just booted to a blank screen). The default recovery on that tablet was all but useless.
Anyways on the new tablet when I boot into recovery mode it is all in Chinese. I obviously don't read Chinese but I would like to have a recovery option should something happen to this tablet. Plus I might want to try to root eventually if can get a fairly high certainty that if something goes wrong this time I can use the recovery menu to actually attempt to recover the Device . Also this time I'll obviously want to try to back things up before I attempt anything.
With all that said how safe is it to flash a custom recovery onto an Android device? Is there any chance of bricking it just doing this itself without rooting? Also how hard would it be?
This device I am using is a digiland d1018a 10.1 inch running lollipop 5.1. Arm cortex quad core CPU. Arm Mali 720 GPU. 1 GB RAM and 16 GB flash memory.

T95Z Plus Freezing

Hi everyone i am new to this forum and can see that there is a lot of people that know their stuff when it comes to android.
i have a T95Z Plus which i have bought second hand and when i plugged it in it would not not boot past the T95Z Plus screen, however with the help of this forum i have managed to shorten the pins and install the stock firmware which was the 7.1.2 as i could not even boot into the recovery.
once the installation was completed i though that i had fixed the box however after it booted up and the main menu came up i tried selecting anything it froze so i unplugged from power and tried again same thing again.
i then re-flashed the firmware again using USB burning tool and same thing again.
i tried other firmware's however i think they are all the same and none of them worked.
i then downloaded the stock version of 6.0 firmware and installed in thinking downgrading might help, however it only lets me use the box an extra 30secs before it freezes again.
"i can now boot perfectly fine into recovery".
i am not sure what the specs are however i think they are as follows:
RAM 3gb DDR4
32gb ROM
i am not sure about the rest and not sure how to find out, any help would be greatly appreciated.
i have the same issue, i think its a faulty nand ...

Thanks for the replay i think so to i have found something strange, i managed to get it running just enough to go into the settings and check the RAM and the Storage, the storage was 16gb and the RAM 3gb, when downloading the firmware it seems that you can only get 16gb storage with 2gb RAM or 32gb storage with 3gb RAM, i'm not sure whether this is a misrepresentation or whatever but it does not make sense.
i have also noticed when i opened the box it was DDR4 followed by some numbers and Chinese letters.
This is why i'm still unsure whether it is the NAND or the wrong firmware.
Regards.
