does anybody have the mini 4.3 inch tablet mach speed technology makes?

I was stupid and didn't make a back up of my original wpa supplicant file and cannot get wifi to turn on at all no matter what wpa supplicant file I try.

You guys think that the process for flashing a rom on this little POS would be about the same as this other mach speed device? I need to figure out something to get my wifi working. Maybe someone knows more about the whole wpa supplicant thing than I do or if someone else has the the same device I have they could hook me up with their original wpa_supplicant file. :fingers-crossed:

can't flash my stealth pro 7c

Been trying to flash my bricked stealth pro 7c without the hdmi port which i'm guessing means i run the a13 chip. I have livesuite v9 and a rom for the a13. I follow the steps (press vol + then connect to usb pressing the power button 10 times briefly over ten seconds) and nothing ever happens. I've uninstalled all drivers and rebooted still nothing. Is the method given for booting into the upgrade mode proven to work for the stealth pro 7c? Does v9 work? I've tried v7 of livesuite and still nothing. REALLY not wanting to give up here but it looks as if i may actually have a fully unrecoverable stealth pro 7c from a failed rom upgrade. they say it is impossible to do but unless i'm doing something wrong(which i truly hope is the case) i've done it.

So could someone please tell me what the correct thing to do to restore my bricked, all black load screen stealth pro 7c tablet?

When you say nothig happens does your computer recogninze the tablet when plugged in? Also try an A10 rom. You may have an A10 tablet like I did,
[Upgrading, Modifying and Unlocking] Meteshjj:
I had the exact same problem. Instead of pressing it ten times over ten seconds, just keep pressing it until Livesuit recognizes it. Make sure you have the image you're going to flash already selected, though. I did this with LiveSuit v1.09, and the MOMO9 firmware a few times, and it worked great. I usually press the power button once ever second, or so. If you do it too fast, it won't recognize it. I've actually had the power to my PC die in the middle of an upgrade, but even that didn't brick the tablet, so I think you're safe. Below is the exact process I use. It works with both of the tablets that I have, one A13 with no HDMI, and one A10 with HDMI.

This is the exact process I use.

1. Plug in the USB cable to both the tablet and the computer.

2. When the tablet turns on, hold the power button until all of the LEDs are off.

3. Start Livesuit

4. Select the image you are going to flash.

5. Press the power button on the tablet.

6. Continue pressing the power button once every second. Do not hold the power button down. Just click it.

-- Note that as the device turns on, your computer will recognize a device. As you continue to press the power button, it should lose that connection, and immediately pick up another one. This is when you can stop pressing the power button.

7. Livesuit will ask you if you want to do a normal upgrade or a format upgrade. I usually format for safety's sake, but that one's up to you.

8. Wait for Livesuit to finish.

9. When Livesuit has finished, it will tell you that the flash was successful, or it failed. If it failed, just click the System Upgrade button at the top, and it will start over. There is no need to restart the process.
[Upgrading, Modifying and Unlocking] rscalliwag07:
Tried what you are doing here but I can never get the condition of no LEDS on. After plugging in the tablet and holding power it goes from a purple led to a blue led but never shuts off (held it for ruffly 120 seconds). Going to uninstall livesuit9 and all the tablet drivers and restart my computer and try again.
[Upgrading, Modifying and Unlocking] Meteshjj:
Oh, right. Sorry, one of my LEDs is not aligned right, so mine go off completely (or so it seems). When it turns blue, that means it's charging. When it's purple, then it's on. When yours is blue, mine is off.
[Upgrading, Modifying and Unlocking] rscalliwag07:
Ya, i have had it ask to install drivers and then install them after plugging in the tablet, but livesuite9 has never recognized it even when the pc will.

Also, I read somewhere that the models without the HDMI port are supposed to be an A13 chip but this manufacturer is so shady i wouldn't be surprised if the threw in the wrong processor. I mean who sells two different models under the same name? It was completely random at the kmart i bought mine from sister bought hers there same time same box inside were two different tablets.

Stock ROM images for A10 model

Does anyone still need the stock ROM for the 7-inch A10 model (Trio Stealth Pro Metal)?

Actually, I have two versions: one is for tablets with a bma250 g-sensor, the other is for tabs with an mxc622x g-sensor. Both are unmodified, with one exception: I added a copy of the su binary to /system/xbin so I could pull these images. As such, they're minimally rooted.

I also have some other stuff for for the mxc622x version of this tablet if anyone is interested: a LiveSuite image that repartitions the NAND and prepares the system for the update.zip of your choice; and an update.zip that I'm just finishing up with another vendor's stock JB 4.1.1.

Let me know what you need and I'll upload it to my GoogleDrive account.

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.

TRIO7C A13 fixed rom

For Mach Speed Trio Pro 7 (TRIO7C) with allwinner a13:

Found a fully working rom (thanks K-JACKS post #239):

F1(A13) 4.0.4 firmware 20121129.1.1.1 194 from lyxfsz

Runs faster than my original image, 3d works, skype works with older version ( 2.5.4.21.162.apk )

Only problem was the accelerometer was inverted (as mentioned earlier by K-JACKS post #239). My device had a mma7660 accelerometer with inverted X and inverted Y axis.

fix was to modify script.bin and script0.bin :

adb shell

mkdir /sdcard/nanda

mount -t vfat /dev/block/nanda /sdcard/nanda

adb pull /sdcard/nanda/script.bin

adb pull /sdcard/nanda/script0.bin

compile: (linux) from github linux-sunxi sunxi-tools

./bin2fex script.bin script.bin.fex

./bin2fex script0.bin script0.bin.fex

vi script.bin.fex

modify [gsensor_para] for mma7660

gsensor_direct_x = 0 (was 1)

gsensor_direct_y = 1 (was 0)

do the same with script0.bin.fex

./fex2bin script.bin.fex script.bin

./fex2bin script0.bin.fex script0.bin

adb push script.bin /sdcard/nanda/script.bin

adb push script0.bin /sdcard/nanda/script0.bin

[Upgrading, Modifying and Unlocking] dolorespark:
Ummm... did you see the posting two articles up from yours? It's all there.
[Upgrading, Modifying and Unlocking] malmostoso:
Hi dolorespark,

thank you for the images. I have installed the JB image on my Trio 7 A10 and unfortunately your image has the same issue with my tablet as all the other images posted in this thread: no wifi :(

Is there anything that can be done about it? Right now the module 8192cu is loaded but when I click on "turn on wifi" nothing happens.

The only image that actually works is a Gingerbread posted a while back, if you want I can upload it and you can take a look at it.

Thank you so much for your help!
[Upgrading, Modifying and Unlocking] dolorespark:
I'm not at home to confirm this, but my tab actually uses 8188eu.ko. If I recall, it loads 8192cu, finds it isn't right then loads 8188eu. If yours came with GB, there may have been additional h/w changes over time that I'm not aware of. A ROM I looked at recently (perhaps the stock ICS for this one) came with a bunch of 81xx.ko's I hadn't seen before - you may need one of them. Do you know which related files were packaged in your GB image? Or, better, can you reinstall it to identify exactly what gets loaded?
[Upgrading, Modifying and Unlocking] malmostoso:
OK here are two ideas: 1) it's some sort of missing firmware (but I read that the firmware is included in the driver) or 2) it's the version of the driver that is wrong: on JB it's

rtw driver version=v3.4.2_3727.20120404

while on GB it's

rtw driver version=v3.3.0_2971.20111128

If version 3.3 can be compiled against JB's kernel and then the .ko can be replaced maybe it would work.

I'd compile it myself but I have no idea where to get the sources.
[Upgrading, Modifying and Unlocking] Chief0x:
please help

Can I have a copy of the image? I have a problem with my Trio Stealth Pro, stuck on boot. I have LiveSuit and some images for other tablets. Not sure how to get it back to normal without the original image I don't have. I'm trying recovery mode or whatever it's called but Livesuit just isn't kicking into action like it should.
[Upgrading, Modifying and Unlocking] dolorespark:
My best guess is that the wifi software is trying to use USB port 1 when the wifi hardware is actually connected to USB port2. Note these lines:

- from the GB rom: <6>[ 108.460000] sw_usb_enable_hcd: usbc_num = 2

- from the JB rom: <7>[ 2541.643883] sw_usb_enable_hcd: usbc_num = 1

This error msg from the JB rom reenforces my hunch:

<7>[ 2541.988214] WRN:L877(drivers/usb/host/ehci_sun4i.c):ERR: sw_ehci is already enable, can not enable again

To test this, I can provide you with either a new script.bin (which is where the problem is) or a whole new bootloader image (which contains the new script.bin).

However, before I can do that, I need to know about your g-sensor. I created images for tabs with a bma250 or mxc622x but the GB rom suggests you have an mma7660. Which image did you use, and does your g-sensor work?

FYI... the firmware is indeed contained in the driver. If you look at the GB dump, you'll see it downloads the f/w a gazillion times before it's happy with the result. I don't recall the later version having to do that so many times.
[Upgrading, Modifying and Unlocking] Meteshjj:
I'm having the same problem, and neither of the firmwares you posted have working G-sensors or WiFi for my tablet either. There is, however, a ROM that I found that has everything except for the WiFi working flawlessly; even the buttons on the side work right. That ROM is Seby's Speed 4.1.1 ROM. http : // www .pandawillforum.com/ showthread.php? 15600-ROM-JB-4-1-1_v2-0-3_Seby-for-LY-F1-Alldro-Speed-E200

I can't post links yet, but you get the idea.

When I looked into the init.sun4i.rc, it said this:

#gsensor
insmod /system/vendor/modules/bma250.ko
insmod /system/vendor/modules/mma7660.ko
insmod /system/vendor/modules/stk8312.ko
insmod /system/vendor/modules/dmard06.ko
[Upgrading, Modifying and Unlocking] dolorespark:
I'll assume you both have the mma7660 - I'll try to put something together. I'll also get the ROM you mentioned to see how to get each capacitive button to do what its label says (I spent a lot of time on this but could only get them all to act like Back buttons).

BTW... if you can't post links yet, uncheck the box below the "Submit Reply" button labelled "Automatically parse links in text". That way you can include them without having to mangle them (that's what I did when I posted the links to these ROMs).
[Upgrading, Modifying and Unlocking] Meteshjj:
That's probably the case, yeah. What I really need help with is finding a way to fix the WiFi card. I have a NANDroid backup of the original system, but that doesn't include the init files, for whatever reason.
[Upgrading, Modifying and Unlocking] kevmodee:
Hey dolorespark!!!

I tried you JB zip with both images - no wifi - I am sure I have that "bad wifi" that won't run any of the roms here.

The seby411 link is here http://www.pandawillforum.com/showthread.php?15600-ROM-JB-4-1-1_v2-0-3_Seby-for-LY-F1-Alldro-Speed-E200

Everything works on this seby rom except wifi. <edit : also the sd card is not mounted and cannot be viewed - there are posts about seby images doing that I think>

On your JB 411 I had no wifi of course. Also side buttons did nothing at all. Auto rotate is checked but not working. Also the icons are fairly large in apps. (not sure if that is a setting you control or some indication of drivers)

Everything else works on yours and feels a little quicker than the seby img. ;)

Thanks for looking at this for us "lost ones".
[Upgrading, Modifying and Unlocking] Meteshjj:
Yep, you're in the same boat I am. And Dolorespark, you have no idea how much I appreciate your help here. I can rewrite Windows registries and compile drivers for x86 systems until the cows come home, but I'm completely lost when it comes to Android.
[Upgrading, Modifying and Unlocking] kevmodee:
I hear you! At least we have gingerbread
[Upgrading, Modifying and Unlocking] dolorespark:
Where can I get that GB image? Examining its script.bin would be the best way to ensure I get the WiFi and other settings right.
[Upgrading, Modifying and Unlocking] kevmodee:
here was the original link I used but I am sure this is the latest 234 that the chinese site offers.

F1+_F2-2.3.4-20120312-0.9.1.img

http://www.mediafire.com/?gd3necyrq3062pd

Interestingly - all the gb's I tried before this one had no sound. Finally this one showed up with wifi and sound. It has been my fallback ROM after all I tried.

1 thing, I never changed partitions before. Since your images did that to my tab I cannot see my SD Card, Is there something I can do to get that resolved. I never messed with partitions before but I thought the seby images changed them but all I see is the LOST DIR so I cannot access the zip's to load from recovery.
[Upgrading, Modifying and Unlocking] malmostoso:
Here is the one I am using right now:

https://dl.dropbox.com/u/1127262/gingerbread.img

I am in the same situation as kevmodee above: no wifi, no buttons. If you can quickly hack a script.bin to test I'd be happy to try it out and at least see if the wifi issue is as simple as changing the USB "port". Good spotting there btw!

Thanks for your help!
[Upgrading, Modifying and Unlocking] dolorespark:
I got both GB images - they're identical, so I'll assume the hardware is too. I also got the seby-speed ROM that was mentioned - I'll see what insights I can gain from it, particularly wrt to the buttons.

Initially, I'm going to put together a minimal package (script.bin and the init.d sensor script) because we may have to go through several iterations. As I've recently learned while struggling to get JB on another tab, drivers from different sources may interpret the relevant script.bin parameters completely differently or expect additional parameters that others don't use.

Every time you've ever used LiveSuite and selected the "format" option, your NAND has been repartitioned. The layout may be the same or different than previously but the partition table is rewritten each time. Now, when you say you can't see your SD Card, what are you referring to, the so-called "internal SDcard" or the external? If the external, then that's a concern for me. If the internal, have you tried to copy a file to it or create a directory? I could imagine that it's missing the usual directories but I'd be surprised if it were truly inaccessible. Come to think of it... are you talking about accessing it when booted normally or when booted into Recovery?
[Upgrading, Modifying and Unlocking] malmostoso:
Gotcha. You do what you have to do, I'll be happy to test.

I noticed that when I installed your JB rom my external SD card (so damn confusing calling them "internal" and "external") got wiped as well. I had a bunch of roms and movies on it, and after the first boot it was all gone. No big deal, as then I could access the LOST.DIR straight away and when I'd put files on it the tablet would see them without problems.
[Upgrading, Modifying and Unlocking] kevmodee:
About FORMAT in livesuit - That is what I thought - I have used seby images that state they do that too, and i have seen access to either internal and external, or both disappear and in one case switch (internal was actually the external and vice versa).

EDIT : Got home - found SD card was cleared - reformatted from recovery and it is back now.

After trying your JB and then trying seby411 again I return to the GB 234 and still noticed that the External is just listing LOST.DIR and the internal one "looks " like the external one in folder layout but has none of my pics and rom zips and a few apk that I keep on there.

I am at work so i cannot look now. After thinking a little, I wonder if my SD card got wiped. I dont think so but I will have to check. I noticed LOST.DIR from recovery too, I think trying to select both internal and the external I would normally select to install the image zips.

Another interesting point - on your JB the side buttons did nothing - so I flashed back to GB234 - only home and settings buttons work on GB normally - the back button never worked. But this time I see the home button on GB and the little top left home on the screen stopped working too.

So I flashed to seby411 and all the buttons work again, even back button and home as expected. Then finally flashed back to GB234, and home is now working.

So it seems that the side buttons on that seby411 have exactly what they need to work.

Thanks again for working on this. I would like to understand the process you go through to do all this dolorespark. I tried to figure out how to make changes to roms etc, but the process and all the pieces required to get there are not easy to figure out. Do you do this as your job, or do you follow some tutorial, or are you just an Android Genius :)

[Upgrading, Modifying and Unlocking] kevmodee:
First. I domt have A13 tab. There are posts a few back discussing A13 roms you should read first.

There are 2 approaches to flashing these tabs.

1. If your tab wont boot up at all try using livesuit and one of the seby. Img roms. Post #82 has steps to use livesuit. If the seby404 or 411 rom has no wifi you may have to use the gb234 rom on post #101.

2. Once you have ICS you can copy zip roms onto your tab and install CW recovery. This is a little more tricky to work with if you have never tried thos sort of thing. I cant remember which posts descibe the steps but theyare in this thread somewhere. Look for CW recovery and ADB steps. There is azip with info on a post here. Ithink Goes1967 posted it so check his posts.

So easier to do img rom with livesuit and more advanced is a zip rom with recovery.

Good luck. And remember I only have A10 not A13 so I am not sure it will work exactly the same.
