As far as I understand we have a Atmel MXT1664S chip controlling our touchscreens. I've been reading threads concerning other devices such as the nexus 4 and the nook hd tablet, which deals with touchscreen firmwares and it seems that the firmwares for touchscreens are not always changed when you flash a new rom.
My questions are therefore: what firmwares are out there for our devices? Is it possible to calibrate it? Can the strange behaviour of the touchscreen that some experience be explained by different fw versions? How can you tell what version you got?

Hi there, I recently acquired a Moonse e7002 (not 7001) and so far, I'm pretty happy with it (it's not perfect but good value for money). However, I have some questions and couldn't find the answer for this device in particular. The problem is, I have a reasonable amount of experience with flashing WinMo but have completely no experience with android.
I read that android 2.2 (this device runs 2.1 update 1) is radically better than previous versions. Is it possible to flash 2.2 onto this device like it is similarly with a WinMo device? If so, where would I find these roms?
I read that there are a lot of clones out there and that all models with the same number (this one is a M701) are completely identical. As such, can I flash the firmware from those devices onto this one?
I found a FW370 package (I think that it is the latest) and my device runs (I think) FW331. What do these firmwares do exactly? Details seem to be non existent at best.
Hey. Ive done a few mods and upgrades already, but one thing has always stumped me about android os and apps. Can anyone explain the variations between the different roms? I understand that the scale and power difference between say a phone and a tablet cause there to be differences, but why is there such gulfs separating to almost identical devices? Take, as a possibly poor example, a yarvik 10.1" tablet and an almost identical viewsonic 10.1" tab. what would stop the viewsonic roms from working on the yarvik? Apologies if this has already been answered somewhere else, I haven't managed to find a similar thread to answer this for me.
Thanks

The main reason the ROMs aren't able to be used on both devices is because they have a different chipset and hardware. And ROMs are designed to work with the specific hardware of a specific device. The only way to get them to work on other devices is to port the ROM you want to that device (Porting ROMs ranges from pretty straightforward to extremely hard).

Hello,
I just ordered the Visture V4HD from Aliexpress and should receive it in a few days.
This will be my first tablet, and I have a very basic understanding of OS and firmware...
I've noticed that the specs of the Cube U9GT5, Chuwi v99 and Visture V4HD are exactly the same. Does this mean the firmware is compatible between them?
I basically gambled on which one to buy and ended up settling for the Visture. The only thing that I fear is that they might slack on the firmware updates.
Is using firmware from one of those other tablets possible in case the people from Visture stop updating the firmware altogether?
Thanks!
PS- I did a previous search on the matter but wasn't able to find the answer.

Yes you can. I have one Chuwi V99 and i'm using the yuandao n90FHD firmware. Chuwi v99, Cube u9gt5, Visture v4hd and yuandao n90fhd thei are all the same tablet, and a few more brands will came.

Is anyone modifying firmwares of these high-res chinese tabs to get more out of it.
Fact is: the producers did not do their very best to implement the latest tweaks etc to their "4.1.1". The most important problem so far is a memory leakage, freezes and an unusably laggyish HD-mode.
We could use some dev-pover on these tabs, They seem nicely built and not too weak if optimized.

A new firmware for Hyundai Play X900 has been released yesterday, it works with the Cube U9GT5 and all compatible tablets.
I made a rooted version here:
http://www.arctablet.com/blog/forum...ted-firmware-from-hyundai-play-x900-20130109/
It's not really smooth yet, but it's better than all other firmwares I tested so far.
so is the CUBE the same as Chuwi V99?
looking to root / install custom bootloader if one exists :good:
Hi .
I have serius problem with my tablet
The problems is with camera when I try to open android camera apps .
Say error "Unfortunately, Gallery has stopped"
I install again latest FW with full swap all data and have the same error .
I try Settings > Apps > All > Gallery > Clear data
But nothing happened
I try with all official roms
I try with Timeless Rom V0004 & Timeless Rom V0005
But nothing happened
I change permissioning on gallery2.app
But nothing happened
ANY H E L P ?
Any fix for the display lag? It's too annoying especially in HD mode! I've tried a couple of ROMs but none seems to fix it! Any advice? Thx!
Hey,
One of the reason I purchased a Shield Tablet was the AOSP-like software, which I hoped meant that I would never need Custom ROMS for it. Well, I couldn't anticipate Nvidia's poor firmwares performances : my tablet is slow and unresponsive considering its specs.
So, I'm considering flashing CM11 on it but that would mean I'll loose Nvidia's apps.
What are your suggestions to replace them ? Limelight, Sketchbook Pro ? Perhaps some Xposed Framework add-ons for Stylus functions ?
If suggestions are many, I'll put them all in a chart.
Thanks !

I'm 90% certain anything else you flash is going to have the same issues, if not more, since every project out there is using an NVidia device tree and kernel with next to no modifications. Nvidia seems to have really screwed up the graphics drivers in this device - Garmin Viago causes an EGL crash, and I'm guessing that most of the lag/stutter issues are due to graphics subsystem sync issues. (All the specs in the world won't fix a deep-down sync bug.)
When I compare technical stats (cup, gpu, chipset, etc) of Shield Tablet 2014 (Gen 1) and Shield Tablet K1 2015 (Gen 2), they are exactly the same. Does that mean Gen 1 Tablet custom ROMs are also compatible with Gen 2 Tablet as well?
I tried to search forums, but I see no mention of Tablet K1 (Gen 2) separately, leading me to think that they might technically be the same and cross compatible at ROM level.
Usually but not always - unless otherwise specified they're compatible in my understanding.

Thanks. I quickly checked info a few ROMs, but I didn't find Gen 2 Tab (K1) mentioned there
They are not compatibles. And partitions are not the same.
The system partition is larger on the k1 so ota's aren't interchangeable but, all of the user created ROMs, recoveries, and kernel's are interchangeable so far. There are no actual hardware differences that aren't cosmetic besides a slot for the stylus and it's sensor.

I've run original Shield ROMs all the way back to Kitkat 4.4 on my K1. I don't really recommend bothering though because the OSs are just more buggy as you go back in time. I think the current Android 6.0.1 is probably the best release ever for these tablets (aside from Marshmallow's removal of App to SD).
I flashed between these with NVIDIA recovery images and installed them in fastboot. Returning to the K1's stock Lollipop ROM always worked fine.
One advantage to running original Shield ROMs is you get Trine 2 instead of that Sim Fallout game.
