NEED HELP Just bricked my tablet!

I installed ADW Launcher and used it without any problems. I had to reset my tablet (pin hole) because of a hanging installation. After rebooting ADW Launcher crashes and I can't do anything because of the messagebox which reapperars immidiately after pressing the close button. How can I switch back to the build in launcher?

Thanks in advance

Have you tried using adb and 'adb uninstall' to remove ADW Launcher?

Check out this link...

http://www.slatedroid.com/topic/11490-android-market-install-instructions-for-imx515-cnddu/

I think only steps 1, 2 and 4 are required for Heropad/GPad

I don't think anyone has MFGTool working on a M10 yet. I was trying to help MasterXBKC get a working ucl.xml to restore a backup a few posts back, but there isn't a working one yet.

Any UK repairer for Gpad Gforce 2

Hi

I opened up my 10 day old Gpad Gforce 2 to replace what I thought was a faulty internal SD but now the thing wont power up

Anyone in the UK with expertise willing to look at repairing it for me please?

Thanks, Scott

Hi,

as stated above, I don't know if I have a herotab at all (see post #337), but I used the MFGTool to flash the gpad geforce v2 firmware (from pandawill) to my tablet and everything works fine since then.

Just in case I attached the logfile from this update. Maybe it helps.

Darkstar.
[Android Software/Hacking General [Developers Only]] MasterXBKC:
I will get on trying from your last post tonight if i have time....

the gpad geforce FW doesnt understand NAND, all it does it install to my SD card

but the Pengfaxin Herotabs cant boot from SD directly. they must boot from NAND

on the side notes, the gpad geforce install from mfgtool does give me a penguin on the screen attempting to boot while its installing, but it fades away untill only the backlight is on with no picture.

after install i still get nothing tring to turn on, not even backlight and led.
[Android Software/Hacking General [Developers Only]] Darkstar2000:
Did you make some internal pictures from the tablet? I thought the internal SD card holds the OS, at least it does in my tablet. It does not say "gpad" on the outside but it works fine with the firmware for the geforce v2.

[Android Software/Hacking General [Developers Only]] Deadside13:
I have Win 7 and I heard about problems finding the appropriate usb driver and i am not sure if debug mode is enabled. I will try this tonight.

Is there any chance to rescue the gpad under its own power? Some mobile devices can be booted in safe-mode or even factory reset with holding keys while booting.

Thanks a lot

Hi.

I had the same problem a couple of times.

The problem is the connector between the the mainboard and the touchscreen. Make sure that it is connected properly. This is quite tricky. To make sure it does not disconnect anymore I fixed it with a piece of duck tape.

Regards,

[Android Software/Hacking General [Developers Only]] GernBlanston:
I have installed on Win764 a driver I think is working...It's the "Elvis" drivers, and I believe, iirc, that I got them from a link at Pandawill...Windows didn't like them when I did a "search this folder", it would fail to find an appropriate driver and install its own like it was USB storage. The way I made the downloaded drivers work was to leave the device manager in windows up and running while I booted the tablet (hold upper volume button + power for 3 seconds to a screenless recovery mode, where "Elvis" shows up in device manager but nothing is visible on the tablet). When the device momentarily came up in device manager, and before windows could load its own drivers, I quickly right clicked on the device and pointed windows to the downloaded drivers, choosing "have disc". There may be a problem with the signature on the drivers, I dunno...

I'll see once when I get home what driver version it is and if it is installed correctly. I think that you and I have the same tablet, with the reset pin, toggle switch (mine locks screen orientation), a 3.5 mm headphone jack, no logo, front camera, and firmware that's dated March 2011. If this sounds like yours, I'm curious: If you'd check your build.prop, it might say a different, more common firmware after ro.build.version, like, say, 20110225.185109 ?

Anyway, I'd really like to find appropriate firmware to give me full market access (my market is borked after an unsuccessful attempt to re-work it).
[Android Software/Hacking General [Developers Only]] Darkstar2000:
Did you get it and have you tried it?

I got mine today and next time I open my tablet I will first measure the pins (at least the power supply) and then just try it. It's pretty small so I think it will fit!

Adb uninstall did the trick. Thank you all for your help. :)

It took a while to find a working driver for Win7 but this one is working (sorry I am not allowed to post links):

iMX_BulkIO_Driver from the pandawillforum thread "firmware for upgraded Gpad" page 6

The firmware from pandawill is a bit too old 2011/01/24 I try to get the new build from 2011/03/11 which was preinstalled on my tablet. If I have it, I will send it to you.

Change Market account

Is it possible to change the android market / google mail account without reflashing the whole firmware? Deleting the /data/system/accounts.db seems to be obsolete with Froyo.
[Android Software/Hacking General [Developers Only]] Species 5618:
Go to Settings -> Account & sync settings, click on your Google account and in the next window click Remove account. On the Account & sync settings page is an option to add a new account.

unfortunately not. A messagebox tells me that I can not remove the account because it is in use by some apps. I should perform a factory reset.
[Android Software/Hacking General [Developers Only]] bqq100:
When you first start MFGTool, does the your tablet show up as "Freescale i.MX51 USB BulkIO Device"?

After the error happens, is it still "Freescale i.MX51 USB BulkIO Device" or is it "Linux File-Stor Gadget USB Device"?

Check to make sure the files in the "OS Firmware" folder (not the files subfolder) match these: http://dl.dropbox.com/u/24097575/MFGTool_OSFirmware_Files.zip

The way mfgtool works is by uploading a very basic kernel and a temp OS directly to RAM (while it's a BulkIO device), then executes the jump command to start up the OS that's now in RAM. At this point the tablet should change into the Gadget USB Device. The find/updated command tells mfgtool to wait 60 seconds for the temp OS to load properly. It looks like the M10 isn't loading the temp OS or it may be loading it properly, but mfgtool can't detect that it's loaded properly. :(

I have adjusted mobile wifi
[Android Software/Hacking General [Developers Only]] JoeKan:
"" sometimes the pengfaxin tabs do that, turn off wifi for 30 secs, then turn back on and connect, its a software bug somewhere in the firmware ""

-----------------------------

Thanks for the reply, but my problem is worse than that. While the tablet has no problem connecting to the wireless router, it cannot get an internet connection.

I'm new to tablets & the Androyd OS, so it is possible I missed a setting somewhere. Everything on the tablet seems to work well, even though it arrived with a dislodged screen which I put back in.

The attached image shows the Wi-Fi working, but the icon next to it has never changed. Is that the "data connection rate"?

Any ideas? Thanks.

Hello

I have this tablet and you're right, build.prop doesnot show the same version.

I got the 11/03 firmware but I don't know if it is ok to use it.
[Android Software/Hacking General [Developers Only]] alberon:
I am a totaly amateur... and just needed my tablet to study VLSI books (!!!).

I played a little with the system which I should not do.

I tryed the ucl that you have posted (it is on page 44 of this thread) and I get these results:

Can you please give me more info about the mknod command.

At the parameters: does 31 assignes to internal nand? 179 to external SD card?

Thanks.
[Android Software/Hacking General [Developers Only]] Species 5618:
Make sure that you have DHCP enabled (both on your router and on your tablet). To check it on your tablet, go to the WiFi Settings page, press the Menu button and tap Advanced. Make sure "Static IP" is unchecked. Alternatively, you can try connecting with a static IP, but such a setup is a bit more advanced and will have to be changed for every network you connect to.

The icon next to the wifi icon on your screenshot is for the 3G connection, it's unrelated to the wifi problems.

Anyone managed to unbrick a dead HeroTab M10?

I think that the u-boot.bin from gpad does not configure the nandflash.

Besides the mx51_babbage_redboot.bin and mx51_3stack_redboot.bin that configure nandflash make use of the rs232 and do not see the updater vid="066F" pid="37FF".

Is there a u-boot.bin that configure nandflash and sees the updater?

Problem

Hi, maybe you can help me, i have this tablet but today when i start the tablet it was freeze in the android charging screen, i reboot it and nothing happens, it's still stuck in that screen all the time.

Do you know how can i solve this?

Thanks in advance.
[Android Software/Hacking General [Developers Only]] alberon:
Get the related firmware files from slatedroid and put them to the root of the sd card.

Then reboot. This will reflash the nand and you will lose all your data.

Take care of what files you use for reflash. I messed with mine and now I have a tablet that goes from bad to worst. At the moment my tablet is not even recognized by my laptop via usb. I tryed to reflash with ATK and I couldn't imagine that this whould be a forthcoming!!!
[Android Software/Hacking General [Developers Only]] manubono:
Thanks for the answer, mine is not gpad it's similar android-2-2-9-7-tablet-pc-cortex-a8-capacitive

I don't know if the firmware is the same as the gpad or if that one is only for that model.

And another question, how can i install the firmware? Just rebooting and inserting in the card the firmware file?

Thanks again.
[Android Software/Hacking General [Developers Only]] Species 5618:
Do you have it connected to the charger? When I power up mine while it's on the charger, a battery icon appears on the screen (and nothing more). If I then press the "home" button, it continues to boot up as normal.
[Android Software/Hacking General [Developers Only]] JGZinv:
Be aware that the HeroTab M10 and Gpad Geforce are nearly identical

tablets... only a couple very small hardware differences. What you "bought"

and what you "received" can be two different things. I purchased a

HeroTab M10 V2 from Merimobiles, and received the Geforce version.

They each have different firmware though. The different versions are described

at SlateDroid.

tianfeng build versions should check out pandawill's Geforce forum section,

as they do support for it specifically over there and have the stock firmware.

Could anyone please help me because i got confused..

Which model to choose of the MX515 that are out now?

Hi guys, all of a sudden I have got the Storage Corrupted message and lost access to the UDisk.

When I connect the Tablet to the PC I can no longer access the UDisc and Nandflash - although the Drive letters are still assigned.

Anyone got any idea how to fix this? I tried to re-flash the firmware but it's no help.
[Android Software/Hacking General [Developers Only]] manubono:
No, that's not the problem and i tried without the charger and the same problem exists.
[Android Software/Hacking General [Developers Only]] JGZinv:
I can only speak to what I've seen between here and SlateDroid, and my own

tweaking of the MID/Gpad Geforce version, so it's entirely possible someone has a different opinion... but I'm going to claim that the Gpad Geforce version has better "support" because the producer seems to be putting out a new firmware every couple of months via pandawill.

Will that continue? I don't know. They released new updates Jan, Feb(minor) and March(minor). I haven't seen anyone putting out multiple firmwares for the HeroTab.

However... the HeroTab seems to come out of the box more functional than the Gpad. Based on most of the SlateDroid posts, other than the WiFi being a problem, the HeroTab is mostly functional and ready for use like any other Chinese tablet.

The Gpad I put 30 hours of learning and tweaking things like the Wifi, the market, putting new launchers, replacement apps, etc on before I could call it "ready." There's still some weirdness with the default Google apps being unable to be replaced/updated (Mail [not Gmail], the newer market, camera, video player). I "think" this has to do with either the android version being reported somewhere, or a updated app certificates issue. Plus we could use some better keyboard config files for the keyboard cases.

These aren't "deal breakers" though. The included standard apps are Eclair versions I guess, but they do work fine. After all the tweaking, I have no reservations about saying my tablet can go toe to toe with a 1st gen iPad, and beat it in many areas.

As the saying goes, what you get out of it will depends on how much you put into it. Hardware wise the HeroTab and Gpad are extremely similar. Even if you order a HT, you may receive a Gpad instead. So there's no guarantee.

Ideally, Cyanogen mod or one of the experienced custom firmware guys would support this group of tablets. Then these things would be truly awesome. Until then we have to learn and modify them ourselves.

My tablet is working fine with this firmware. I hope that I never need to reflash because I didn't get the original stock firmware image. The brandsdragon.com site is unavailable at the moment.

My tablet won`t charge unless it`s turned on. When I leave it turned on and charge for the night, the next morning it`s dead and I have to reset it by poking the little hole......

I`ve got the tablet for a week now, and it has never showed 100% battery so far....

It`s the 8GB model with stereo speakers and 3,5mm headphone.

Did anyone experienced the same problems?
[Android Software/Hacking General [Developers Only]] JGZinv:
Sounds like a regular HeroTab M10 version with pengfaxin firmware.

Although I don't think we've seen a 2 speaker version so far.

pengfaxin's seem to have the reset hole while the tianfeng's don't.

Well for the short term you could set the tablet to never sleep...

then it should stay on and charge while "awake" all the time.

Sounds like you should try to reflash the firmware. If that doesn't do

anything than it's likely a hardware issue.
[Android Software/Hacking General [Developers Only]] bqq100:
I think there may be a typo in the ucl.xml file. the miunt command should be "mount /dev/mmcblk0p1 /mnt/src" (remove the extra c).

The mknod command creates a virtual character device that android/linux can read/write from. It associates a phyiscal device (referenced by a major and minor number ie 179:1 for the sdcard) to a special file (ie /dev/mmcblk0p1) that linux can mount.

179:1 should be sdcard1 partition 1 (internal sdcard for dual sdcard tablets, external sdcard for single sdcard tablets)

179:9 should be sdcard2 partition 1 (external sdcard for dual sdcard tablets)

31:4 is hopefully the internal nand memory of the heropad

Hi,

I bought a BCM92046 on ebay but I came already damaged. I tried it, but it did not work, neither inside the tablet nor manually connected to the PC USB port. I really think that the 8pin header is to connect such a bluetooth module and just ordered another one: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=320614784085

The cable looks as if it could fit already, the other one I have did not so I had to solder a little. I will keep you up to date if it works.

Mine starts up to the Android screen and then flashes from green and black. I'm looking to sell it to someone who has the heart and energy to fix it and give it the love and attention it deserves. It comes with two cases, a charger, and an iPod cable as well as USB keyboard adapter. I will also include a ZAGG screen protector I bought (but never installed) for it. Developer's special. I'll even include the 8GB microSD card I have for it. I paid $280 for the tablet and the leather case the seller had. I recently bought a $40 case and paid $25 for the 8GB card and $25 for the screen protector.

I recently had to open it as I was fiddling with it in the dark and I placed the microSD card in the open slot rather than the microSD one (had to dissect to fish it out)

$250 sound fair? (I'm flexible)

That's the FW that mine came with so not sure where you can get it as a download. It's a nice fast, stable platform though.

Prior to this I had a Superpad2 Flytouch3 10" tablet which was a nice device but the Herotab is a marked step up from that one. A much nicer user experience (including Flash which works reliably).

Is anyone interested in helping me petition pengfaxin to release an updated firmware? I have a non-functioning device (juts sits at the flashing ANDROID_ prompt). I have tried e-mailing them directly but they seem to be ignoring me.

I was thinking if we could get a number of owners together that are having problems and contact them as a group they maybe more resposnsive.

Unfortunately the online store I purchaed from, pricedinchina.com, also appear to be ignoring my help requests.

The ideal situation would be to get someone from here who speaks Chinese to call them and get them invloved in providing solutions.

At this stage I would urge anyone reading this to avoid purchasing a pengfaxin based device until they are prepared to offer a resolution.
[Android Software/Hacking General [Developers Only]] bqq100:
Did the flashing ANDROID_ prompt happen after a you tried to flash a new kernel or system.img? Do you have a backup to restore? I thought that the heropad could be flashed just by putting the files in the root of the sdcard. If you're getting to the ANDROID_ prompt that should still work.

[Android Software/Hacking General [Developers Only]] matt205:
No, I had resisted the temptation to try new firmware as the Device was working fine. It simply crashed one day and after re-start just went to the flashing ANDROID_ prompt. It's looking more like a NAND hardware problem I'm guessing. It'd be nice to get some support form the seller and or manufacturer though. Damn thing is meant to have warranty, shame the seller just ignores my requests, take the money and run I guess. pricedinchina.com or chinagrabber.com, steer clear.

If I try to reflash from SD it has displays Chinese charcters on the screen, I assume the translation would be "reflashing firmware, please wait" or something, but then just goes back the the flashing ANDROID_.
[Android Software/Hacking General [Developers Only]] bqq100:
Perhaps creating a blank file called data.img (in addition to the other files for reflashing) would essentially do a factory reset? Just a shot in the dark, I don't know if there is anything that could happen on the data partition that would cause bootup to stall on that screen.
