I got this tablet sold by Mach speed technology for about $90.

Specifications:

Dimensions- W7.5” x H4.8” x D0.4”
Operating System- Android™ 4.0 (Ice Cream Sandwich)
CPU – A10 Cortex A8 1.2 GHz
GPU – Dual Mali-400 2D/3D core
RAM – 512MB DDR3
Flash storage – 4GB Internal
Display – 7 inch TFT LCD
Native Resolution – 800×480 pix
Expansion – Micro SD card slot (up to 32GB), Mini HDMI Socket
Wireless LAN – Realtek 8188 (mine is 8192 which made it work with ICS custom ROMs)
Video Output – HDMI Ver 1.4 output
Native video support – AVI(H.264), DIVX, XVID, RM, RMVB, MKV, WMV (non encrypted), MP4(H.264, MPEG, DIVX, XVID), MPEG, MPG, FLV. HD 1080P max.

There are no information online regarding this tablet and it is hard to know anything further about it. Technical support sucks, so I thought of sharing my experience here maybe will help others.

This tablet is an LY-F1 clone, and I was able to install custom recovery, as well as a CM9 based ROM on it, now this tablet is running very well for its value.
If you need further assistance I will be happy to help.
Li ink to the ROM HERE.

Thanks for the info. I have been thinking about getting something like that. This post got me more interested:

http://forum.xda-developers.com/showthread.php?t=1821398

I've been trying to figure out if there's a way to make calls with one......Google Voice should work is the tablet has a mic.
Some say they support GSM and I'm on ATT. That's what I need to know about before I get a tablet.
It would seem impossible if there is no way to insert a SIM card in the tablet.....but I can still hope. ;)

I tried the CM10 ROM both previes 2 and 3, none of them worked on my tablet, this is why I don't mention it.
As for making phone calls using such a device, don't think it is a very good idea, the mic they have it on these devices must be of a much lower quality than the ones used on dedicated devices such as cell phones. I tied Skype and Google talk though and they were OK.

I just purchased mine today and would love some assistance because tablet needs a new Rom bad. Which custom recovery are you using? I tried using the original recovery and it just sits at the android with his chest open. Please lead me to the promise land.

First you need to flash CWM recovery from here https://www.dropbox.com/s/lp4ev9cnp7joq3y/CWM Recovery 5 ICS.zip, follow this instructions.
Then go to this thread and install CM9 http://forum.xda-developers.com/showthread.php?t=1760929

Okay I went with the aokp Rom once I tried the cm9 Rom. Cm9 was freezing a lot. I tried aokp and used go launcher with it and this thing runs buttery smooth. I'm buying another one.

what happened

Great news, now you know what you are doing:))

ok, i'm getting an error somewhere or a glitch did everything step by step but have no wifi? any ideas....i retraced my steps and tried both the lyf1 1.1 and lyf1 1.2 getting the same result, i'm missing something here just having trouble figuring out what it is, plus i made the sweet mistake of forgetting to make a backup of the stock ROM with CWM5 prior to switching Roms so I'm stuck here...does anyone have a backup saved?

Use livesuite to flash the LY-F1 original firmware here and then start all over.

This is the same tablet I have, which is a clone of THE LY-F1 use the link in my post above to flash the firmware and see if the WIFI works, if it did try using the compatibility zip posted in the third party link from Christian Troy.

I am now using the AOKP port by Christian Troy, which is giving me a couple of things over CM9, first it is giving me a bit more free ram, which is very much needed for this tablet, second it a tone of tweaks that we can play with.

I'm in the same boat as xtreme... I flashed to AOKP0708, installed gapps, then 1.2.0... soft keys and wifi weren't working so I rebooted into recovery again, installed the 3rd party cbw.zip...

I've tried a couple different versions of AOKP, and the Original LY-F1 firmware you posted (which was in Chinese/Japanese, that was a good time! :p haha), wifi didn't work on any of them.

    SOLUTION FOR YOUR MACHSPEED TRIO 7INCH READ

    just ordered another one, also just bought the Samsung galaxy tablet 2 7.0. It's rooted and custom ROM ! love it. As for the Trio.. Very disappointed lol

    I know what a piece O`[email protected],I had it for 10 minutes before I decided it needed Google Play so i imediately tried the procedure in the OP and BOOM semi -bricked and nothing worked until I tried an A13 image ,the OP states in it A10 which is understndable because that is what it says in the specs,but as soon as I installed the ROM and the compatibility file it crashed on me which sucked because it was a present for my kids and I had to put it under the tree not working,but After finding a bunch of images I narowed it down to 2 images for this device which work the best which is the F1 (A13) 4.0.4 firmware update to 20121129.1.1.1 at link http://www.lyxfsz.com/cn/downs_view.htm?id=63 which doesn't have the orientation correct (inverted-upside down ) but everything else works and last but least my final choice which everything works but not the greatest battery life which is called mom09 hyper edition Image file named - TRAGiC-A13-DEC2012-404-ICS.img which can be founde here with instructions at this link http://www.androidtablets.net/forum...eneric-7-a13-android-4-0-4-hyper-edition.html PLEASE NOTE that these come pre-installed with Google -play and I would recommend installing SuperSu,Root Browser Lite,SetCPU set minimum above 700 and leave maximum alone it appears that this CPU is already maxed out at its current maximum setting because it wont behave with any higher setting I have found out also use adaway to minimize the ads and maybe try battery calibrator app and memory booster. as I stated this one works the best however WiFi signal is a bit weak at times the fixed buttons on face don't work but are not needed and orientation works fine in all apps including Netflix as well..you will need Live-suite to flash this image and follow instructions from the link above if you don't know where to get live-suite I suggest Google it or check in this thread if the link from a previous post still works ..I would post Live Suite but I am not sure if it is considered WAREZ or not..I know I posted similar post with some of this info but this has more of final info ..Anyways I hope this helps Someone ,I know finding and researching is frustrating and if you don't know what you are looking for exactly you will never find what you need so Again I am posting this in an effort to help the community with a solution to get there MachSpeed Trio 7 back to a working state with Google-play etc..
    EDIT LINK TO LIVE SUITE 1.09 HERE http://www.4shared.com/zip/u8bgCi3y/LiveSuitPack_v109.html
    I would like to thank the original Devs and Contributors to these links I provided I am not sure who to thank ,but please know I apreciate your hard work and efforts..
    IF THIS HAS HELPED YOU IN ANYWAY OR AT LEAST POINTED YOU IN THE RIGHT DIRECTION THAT MEANS I DID MY JOB!!!SO PLEASE PRESS THANKS TO SHOW APPRECIATION FOR THIS INFO..... PLEASE!!!THANKS!! HAVE A BETTER DAY!!!

    Confirmed success on Trio + Tips

    I have recently installed successfully the ROM mentioned in post #237 (Ployer/MOMO A13) on my Trio Stealth Pro 7c (A13). I can confirm that it boots fine and WiFi works on it.
    Here are a few tips for the process:

    1. The ROM download page requires a password, the page indicates that "The password is updated". You need to read that sentence literally: type the word "updated" into the password box...

    2. The UI upon boot is in Chinese. to switch to English: launch the settings app, select the item with the icon that looks like an "A" (languages), then select the first item on the top. The next screen will be the list of languages (in English). select the desired language.

    3. The keylayout files provided in this ROM map the volume-up and volume down buttons incorrectly. (volume up triggers volume down, volume down triggers "menu". To correct this follow CAREFULLY the following procedure:
    - Download a file explorer app that can work in root mode (I use es file explorer, then turn on the root options in the settings menu)
    - navigate to the following folder: /system/usr/keylayout
    - find the file sun4i-keyboard.kl and edit it as TEXT
    - find the line "key 139 MENU", replace it with "key 139 VOLUME_DOWN" (AFAIK this file is case sensitive!)
    - find the line "key 114 VOLUME_DOWN" replace it with "key 114 VOLUME_UP" (AFAIK this file is case sensitive!)
    - save the file
    - reboot

    A few additional notes:
    - The 3 buttons on the front don't work. I didn't find them very useful anyway
    - The camera works
    - Google play works
    - Video playback seems improved (I use dice player)
    - accelerometer doesn't seem to be working, screen does not auto rotate (probably a driver missing, will try to find a solution next)

    Trio 7 A10 images

    Edit: These ROMs are NOT compatible with a A13 tablets like the Trio Stealth Pro 7C. If your tablet does not have a working HDMI port, do not install these ROMs.

    I've posted several packages to my GoogleDrive. All of them can be had from this folder: Trio7-A10 There are different versions of these packages depending on whether your g-sensor is a bma250, an mxc622x, or an mma7660. The first two are below, the third (with the mma7660) is described in another post: ROM for WiFi-challenged Trio A10 Tablets

    Two of them contain raw disk images taken from near-virgin tablets. It's up to you to get them installed (e.g. cat bootloader.img > /dev/block/nanda). They are: trio7-a10-bma250-stockimg.zip and trio7-a10-mxc622x-stockimg.zip

    A better choice for most people is the combination of a LiveSuite image to prepare the tablet and an update.zip to install a stock JB (4.1.1) with extra features.

    LiveSuite Images - trio7-a10-bma250-dopa-v2.img and trio7-a10-mxc622x-dopa-v2.img
    Each .img repartitions the tablet's NAND to increase the size of the /system and /data partitions, then installs a bootloader, CWM 6.0.2.8 recovery, and a temporary boot partition. The first time you boot after flashing, it will format various partitions then reboot into CWM so you can install an update.zip. Note: The .img file is only 25mb because it contains no usable /boot or /system partition - you must install either my JB package or another package such as CM10,

    Update Zip - trio7-a10-jb-dopa-v2.zip
    This installs a stock JB 4.1.1, the basic GApps (including PlayStore), and a few useful apps like ESFileExplorer. It is fully rooted and provides init.d support. Beside adding a few tweaks taken from CM10, init.d is used to install the proper gsensor driver and support files, and to move the dalvik-cache to your /cache partition, freeing up 75+mb on the /data partition. Note: Neither this version of JB nor CM10 will fit into the stock ROM's 256mb /system partition. If your /system partition is already larger (300mb minimum), you can install this zip without using the LiveSuite image - it will not touch your /data partition.

    bma250 or mxc622x?
    Good question, few easy answers If you're still using the stock ROM (and are rooted), look in init.sun4i.rc in the root folder to see which driver is loaded. Otherwise... The older your tablet is (at least 6-8 months), the more likely you are to have the bma250. If you've installed numerous ROMS and have never been able to get the gsensor to work, you probably have the mxc622x. If you've never been able to get WiFi to work with any ROM you've tried, you probably have an mma7660 and should refer to the post described above. If all else fails, try both LiveSuite images (you will have to reinstall JB if your first attempt fails.
