[Acer Iconia Tab A100] pio_masaki:
Nothing can repair a tab with emmc failure. The kernel is preventative.

Log onto Acer.com and go through their chat with a rep process. There they'll tell you if its covered or not and what to do about sending it in for repair if that's what is decided upon.

That recovery app wouldn't work without being unlocked, so if you never did that then you never had a custom recovery and that leaves hardware failure if some sort.

Yes and no. What we came up with is wear leveling is causing it. The emmc controller accepts a command from the kernel it can't actually do, then begins to blank the emmc, usually killing the gpt. Its been covered elsewhere, so I won't get to crazy on details, but it will happen stock or not. /cache usually triggers it as its most written to, however anything can trigger it.

Flashing and wiping cache can accelerate this issue. My tab had it after 3 months, usually it seems to be 6+ months of normal use to see it. Completely stock ICS never flashed seems to go a year or so, maybe.

Mine had failure pretty quick as its a dev device, in particular developing the black hole nullifier which writes zeroes over each partition. Flashing ROMs and wiping twice or even up to 8 times in a day accelerates the issue also.

What should I say is the problem? That all sounds pretty complex..lol
[Acer Iconia Tab A100] droidxxxxx:
Well..that was pretty painless..gonna mail that sucker tomorrow.. I had 113 days left..thank bejeezus.. lol
[Acer Iconia Tab A100] pio_masaki:
I was gonna say tell them its not booting lol glad it worked out.

I gave a brief description.. and chose "system hangup" as the issue.. Acer in Texas will be fixing it hopefully.
[Acer Iconia Tab A100] droidxxxxx:
After they fix it..hopefully it won't do it again..I sent it off today..
[Acer Iconia Tab A100] mr.miketastic:
I had the same issue. I tried installing a stock rom from ext SD, and several other recovery methods found in various threads, but when I started the tab up, whilst holding volume button farthest from the rotation lock and toggling the rotation lock, it actually reset everything back to the day I brought it home. It booted into the original HC, and I was able to get the ICS OTA update. Seems to be none the worse for wear at this point.
[Acer Iconia Tab A100] droidxxxxx:
Ok..got my tablet back yesterday from Acer..they fixed it very quickly..props to their warranty department. Now..I assume I got a new main board replacement..which is great..but now..I am on the original honeycomb os..I have tried the update wanting to return to ICS..but it says none is available. Also the market is not upgrading to the Play store..and it forces you into landscape, even if the lock is disegaged. Also, the market is not finding all my apps..and even not recognizong ones I've paid for..and worse of all..is the honecomb camera..it sucks..no panorama..which I was using daily at work. Can I get ICS back? Anybody else having this issue with a repaired a100?
[Acer Iconia Tab A100] Romman0:
Slap this stock ICS ROM on your microsd card, named update.zip. http://xdaforums.com/showthread.php?t=1611696

Power off, then press and hold the power and the volume rocker closest to the corner simultaneously for about 5 seconds. The tab will vibrate and update to ICS. Let it sit until it is done. Then there should be a few updates if you check for updates.
[Acer Iconia Tab A100] droidxxxxx:
Ok..will try that later tonight..it doesn't need to be unlocked or rooted for this?
[Acer Iconia Tab A100] pio_masaki:
It only needs unlocked for custom or modded ROMs, thats a stock leak (if its what I'm thinking) and passes the bootloader locks and recovery fine.

[LG Optimus 2x] TrymHansen:
For the last week or so I've had this very strange Google Play behaviour. It basically goes like this:

1) You download an app. Everything's fine, you download at full speed.

2) The second time you download the app (to another device or reinstalling) download gets capped at exactly 1Mbit/s.

For me this is completely reproducible. A new app I've never downloaded before gets downloaded at full speed, any other attemps to download the app get capped.

Does anybody else see anything at all resembling this? I have some theories, but I need more information.

Would especially appreciate feedback from Altibox-customers in Norway.

Guys first off this is not my work and have been digging around for answer. I had recently bricked my TF201 and it was stuck at the Asus logo. I was on JB via OTA and my duma$$ tried loading 3d chainfire to get Dark Knight to work smoothly. I'm sure this will work for soft brick during a failed OTA. Finally found a fix! Now you will lose root with this just FYI.

Got the instruction here on how to restore tf300 back to stock. Please thank Auliyaa for his method.

http://xdaforums.com/showthread.php?t=1757077

Got the adb and fastboot from here and follow the instruction how to use them.

http://dottech.org/21534/how-to-ins...ows-computer-for-use-with-your-android-phone/

Luckily JB updater has been updated today on asus website so grab it there. Extract it and get the blob. Copy the blob to wherever you have the fastboot files. In my case I put it under C:\android

http://support.asus.com/Download.aspx?SLanguage=en&m=Eee+Pad+Transformer+Prime+TF201&p=20&s=16

This is the instruction from the first link. Updated a few things on it to reflect the correct links for us. I'm going to post in that thread that this works on the tf201 as well.

Download the stock ROM zip file on Asus website (updated). Be sure to download the firmware matching your SKU.

Unzip the downloaded file, you will get another archive called , unzip this one too

You should end up with several file, with one of them called blob

For the next step, you will need to install the Android SDK to get the fastboot utility from here(updated)

Once you have installed fastboot, boot your tablet into fastboot mode (Plugin your tablet on your computer's USB, Hold down Power+VolDown, dont press VolUp when prompted, select the USB icon and press VolUp)

Open a command line terminal and navigate to the folder containing the blob file.

Then type the following command:

fastboot -i 0x0B05 flash system blob

Once the transfer is done and you get that sweet "SUCCESS" printed on your screen, just type the following command to reboot your tablet:

fastboot -i 0x0B05 reboot

Thats it! OH man I was bout to pack her up and send to Asus. I love XDA!

[Nexus 7 General] e.mote:
I'm curious why you're using narrow-beam ant for your drone. Those panel types usually have a 30-deg beamwidth, and are for point-to-point uses. Actually, a hi-gain omni probably wouldn't work either, since it has a "flat" beamwidth. Maybe something like the below, a 9dBi panel ant w/ 60-deg beamwidth for easy aiming. The compact 5"x5" can be mounted on the tablet with a clip mount.

[Nexus 7 General] lithium630:
That's pretty sweet. I would love to add an external antenna to my (planned) car install. Having zero soldering skills, I don't know if I'm brave enough.
[Nexus 7 General] b00mb00mchuck:
I guess the answer would have to be trial and error + results...

I've racked up quite a few different antenna styles while experimenting... these are just a few

Omni antennas came first because I had them lying around and they did wonderfully compared to the stock internal antenna... but then I ended up with one of those 5"x 5" patch antennas (center) and saw the advantage of directional (narrow beam , point to point... just point it at the drone) ... so I scrounged around and settled with the 7"x 7" because it gave the best range... to me, 30° beam width is big... by the time you get 100/150 yards away the error cone is huge... pointing my nexus in the general direction of the drone seems to come naturally so it's never an issue

Of course it's not the antenna I use when I'm browsing XDA on WiFi like the post I'm making right now from the little 5dBi omni (second from the right).... small and light and doesn't get in the way...

All comes down to single user preference... would be silly to market something this way because there's particular rules to follow to get the best results with that particular antenna... but it suits my style and requirements the best... I'm even thinking about going up a notch to an 18dBi patch that only has 20° beam width... just to see how far I can actually fly this thing :D
[Nexus 7 General] CJHolderUK:
Oh my ****. Cool! :D
[Nexus 7 General] b00mb00mchuck:
That was my fear... I went at this with sketchy soldering skills also... but I watched some YouTube videos... and practiced a little and boom... came out just fine
[Nexus 7 General] squbel:
This is incredibly amazing. Now... where is the step by step mod guide with pics? :D
[Nexus 7 General] bigbop:
Yes! Another hardware hacker who's not afraid to 'play' with his toys.

I watched the videos and kept an eye on the battery gauge of the AR Drone. When you crank up the speed, it really sucks down the battery quickly.

Where did you get the main bracket?
[Nexus 7 General] kenyee:
Very cool hacking.

Funny how you can watch the battery dropping when you sped it up :)
[Nexus 7 General] b00mb00mchuck:
The main antenna bracket is a hacked up Motorola Droid Bionic windshield suction cup mount (car dock) with the suction cup removed, 4 holes drilled for the antenna connection, and some cutting and flattening for the tablet connection with epoxy and small screws...

The battery drain is partly from more aggressive flying and partly because I sped up certain parts of the video edit to keep it more interesting... that was actually a 17 minute flight compressed into 7 minutes of video without dropping any frames... just speeding up the slower moving, boring parts
[Nexus 7 General] tenble:
That's some impressive customization there. Props
[Nexus 7 General] b00mb00mchuck:
I could probly pull that off here pretty soon (this weekend?). I have a new SMA connector coming with thicker, low loss, RG174 cable... (the coax i got on there now sucks)... and I'm making a stronger SMA mount... I made the first one kind of like a kickstand to keep the tablet tilted when I set it down, but I keep feeling like I'm gonna break it off sooner or later

So yeah... I'll be sure to take pics... maybe video I guess? (Which would be better?) :eek:
[Nexus 7 General] kieso:
I'm so jealous. I was just looking at the ardrone website a couple days ago and have been trying to think of how to tell my wife that I need it to function as a human being.
[Nexus 7 General] khaytsus:
Google "ar drone flyaway" before you do that. The folks who make it still haven't figured out that "wifi connection loss" should mean "gentle descent" to the ground. Apparently it means "go off in some wild direction, sometimes gaining great altitudes".
[Nexus 7 General] b00mb00mchuck:
Not a problem for 99.99% of users... when mine loses WiFi connection it stops and locks on a target on the ground and hovers... giving me time to walk closer or aim my antenna better and reconnect... you really don't want it to auto land on a disconnect... what if it's over water or power lines or trees etc... the hover and wait feature works very well... the flyways are usually freezups in the onboard software getting hung up on the last command received ... or navigation board faults

but look at the numbers... with over a million units sold... and doing a YouTube search shows less than 30 flyaway videos... searching the drone forums with thousands of members, shows less than 30 or 40 posts talking about flyaways... and they're all old posts

With my friends and myself as a group we have over a dozen of these things and had one flyaway... Parrot warrantied that and sent a new unit... but that WiFi thing doesn't happen... they always just stop and hover and wait for you
[Nexus 7 General] b00mb00mchuck:
My wife was way harder to deal with when I told her I needed the Nexus 7 more than air

And then she woke up one morning and saw me drilling holes in the cover and just about stabbed me with a back scratcher

But then she saw all the results and comments I get on the drone forums ... and she started thinking it was pretty cool

Then, all excited, she sent me this pic at work and I realized she was totally down with the DroneLife

My drone made the Parrot AR Drone Facebook page
[Nexus 7 General] CrunchyBandit:
What a beautiful drone :o

Did you end up with that antenna and booster because of weight limitations, was it extensive experimenting, or did you just toss it on there and work on your nexus 7 antenna? :p
[Nexus 7 General] mat helm:
Yea I've never had much luck with floating, even with things that are meant to.....

Wondering if you've had an engine or prop failure yet? Nothing to do with the pond thing, just wondering. I've never understood the quad design because it seems to me that if it can't fly with 3 out of 4 motors, then why not have a three engine design. I mean a tri-motor couldn't fly either after loosing an engine, but there'd be one less chance of failure. And a 5 or 6 engine design could loose one or two engines (respectfully) and maintain level flight, or at least level descent....

Sorry, just thinking out loud here. Have always wanted to build one, only larger and gas powered for longer duration. Thinking maybe even a gas electric.... oooooo ..ahhhh...:cool:

Course the numbers always come up short on that last one....

[Nexus 7 General] Ryan79:
Parrot provides both a "repair kit" which is really thin double-sided tape.... you put it on one side of the broken section, peel away the protective cover, and connect the other side of the broken section; as well as full on foam replacements.... do a quick search on Amazon for AR drone replacement parts.... almost everything on the drone is replaceable

---------- Post added at 01:17 PM ---------- Previous post was at 01:05 PM ----------

the AR uses brushless motors.... lot less likely of a motor failure. As for a quad design, more motors means more control & stability.... with 4 the motors have to use less energy to accomplish a given task. You can go with a 5 or 6 motor design.... kind of an over kill for the AR, but then you also have to factor in energy consumption, blade clearance & weight. It is doable.... for example: http://www.safarious.com/en/posts/4638-ufo-sighted-in-south-luangwa

here is a 6 motor design, with counter-rotating motors on each arm... provides stability & control for the camera platform it's carrying.

Hi Chuck

Best Mods ever!!!! wonderful!!!!

Please do you or anyone else have links on how to do this wifi mod on the AR Drone 2.0. Im very happy with doing it, it looks neat and tidy and was wondering if there were stage by stage photos or at least shots of all connections and parts etc.

Also I have ordered a new back for my Nexus 7 but again was wondering if you guys had internal pictures of how you soldered the pig tail to the pins and images of inside the back of the case. I'd like to mount mine dead centre on the Nexys and have shedloads of Antenna to try from previous Router mods.

Any links photos help much appreciated
[Nexus 7 General] b00mb00mchuck:
Sorry I slacked off and never took pics while I was doing the mods but I never thought it was gonna get this kind of attention... I've been wanting to take things apart and get some good pics but it's one of those "don't wanna mess with it unless I have a good reason" type deals... That booster that's shown in the drone isn't the one i use anymore ... It was really old when I got it and didn't last very long... The one I use now is stripped from a Hawking WiFi booster and it is NOT an easy mod to pull off... Two PC boards have to be separated and re-stacked and soldered back together and it's a bummer... The nexus mod is pretty well described in the first post here though... It's a pretty straight forward hookup and I labeled the WiFi connectors on the nexus board.
[Nexus 7 General] slarty01:
No worries and thank you for the reply. I wonder if the round antenna is a good idea? I do like the way the antenna on yours is so discreet. So you boos the signal on the drone and use the massive antenna or was your flight stock but the nexus working with large antenna. Lastly is there a connector on the mother board to take a pig tail connector or is it located in a specific place.

PS have you seen the AR Drone Flight Recorder on their blog? http://ardrone2.parrot.com/flight-recorder/

Many thanks amazing work
[Nexus 7 General] davidoff59:
Could the pogo pins be repurposed and used for this? That way everything would be internal with no visual mods externally. 2 wires running internally to the pogo pins, set up a dock system with the connectors for the repeater mounted to it with the repeater connected also.

I may be talking nonsense and it won't work but hey, its a thought. Like who would have thought anything in this thread would have worked as well as it does before it was posted here.
[Nexus 7 General] mat helm:
Pogo pins are not active at all times. They have to sense a connection...
[Nexus 7 General] davidoff59:
They would no longer be used for their intended purpose, they would just be used as an outlet for the wifi so they should be active when WiFi is on. They would be rewired for this purpose.

So instead of drilling the rear cover as an outlet for the wifi repeater connecter, run straight to the pogo pins and have the connecter mounted external and on the mount itself.the device is then stock to look at but can easily be connected to the WiFi extender.

I hope it makes sense now.
[Nexus 7 General] b00mb00mchuck:
I see the construction of the pogo pin hardware inside and it is totally doable... BUT... RF is a picky beast... Antenna signal has to be contained and shielded in coax until it reaches it's antenna... If you had to split the wiring to connect to the pogo pins and also on the outside to connect to your dock pins... That would represent a huge leak in RF signal and cause all kinds of degradation ... Not saying it can't be done... But if given the choice I'd much rather have my setup... Totally shielded from WiFi chip to antenna... Cheap and easy hookup...

And another problem... Where would you get your WiFi from when you disconnected your dock? The Nexus antenna has to be removed for this to work so you need to be able to pop on a small rubber bullet antenna or something for the tablet to access internet.
[Nexus 7 General] CrunchyBandit:
Please get some up soon, share with us your treasure :victory:
[Nexus 7 General] indestructibleguy:
Totally off topic.....

could it be possible to somehow attach the antenna to the sound jack, so whenever earbuds or earphones were plugged in they would work as part of the antenna and extend the range?
[Nexus 7 General] b00mb00mchuck:
Nope... That is a huge idea though...

Imagine if a company would implement that for WiFi... There are phones that already do that for the FM radio and apps that go with it that won't start up unless the headphones are plugged in.

The trouble with WiFi is that it is such a high frequency at 2.4gHz the antennas have to be specifically designed to match the wavelength or they can make things worse instead of better.

The thing I've been working on here is a snap on case... Imagine being able to just drop the Nexus into a nice hard case that triples or quadruples your WiFi & bluetooth signal... THAT would be awesome... Not everybody wants to invade the guts of the tablet and void the warranty and make something permanent that is irreversible the way I have done... So making this a "snap on" accessory would be a way more consumer friendly way to go... Although it won't work as well as hardwiring to the Nexus WiFi chip... It will be a significant boost to normal WiFi dB numbers.
[Nexus 7 General] indestructibleguy:
Two things, then. Do you have any designs for a smallish antenna, one that plugs in and out? Second question, other than having a coil inside the case, i don't see how that could be snap-on..... :confused:

**GO MAKE SOMETHING HAPPEN - I.Guy*
[Nexus 7 General] b00mb00mchuck:
Don't know if this is what you mean but my tablet has a standard RP-SMA jack on the back so I can use pretty much any antenna I choose...

And the snap on idea will use a small 14dBi directional panel that's about the same size as the back of the tablet... And an inductive coupler patch over the tablet internal antenna to pass the stronger signal thru the tablet cover... The Nexus 7 internal antenna location is turning out to be the weak link because it's located right on the curved edge of the back cover and the inductive patch is flat... I hate to use the i-word but this whole theory is working much better on my sister in laws iPad 3 with the flat WiFi antenna right under the apple logo... :mad:
[Nexus 7 General] indestructibleguy:
How did you add the rp-sma jack to your N7? And.... And... Hmmmm.... Maybe extend the case on that side, add a stylus holder, maybe?

**GO MAKE SOMETHING HAPPEN - I.Guy*
[Nexus 7 General] nextelbuddy:
THIS

my buddy just got an AR Drone and is already wanting to extend the range.

Im good with electronics and just need to know where to get the RP-SMA jack from and then I could solder it to the N7s board and drill a hole in the back plate with a dremel/rotozip

your videos are sick and love your ideas. thanks so much for giving so much information for us to use.

I assume you are not using the flat 7x7 huge directional antenna now right? but instead something more inconspecious?

how is that PS3 controller mounted? I'm curious about that black piece that goes from the controller to the N7. i have tons of controllers left over and would love to do the same thing.
[Nexus 7 General] b00mb00mchuck:
I use THIS rp-sma connector... Yeah , it's from China and it takes awhile to show up but it has the thin coax wire you need to fit under the nexus back cover to the hole you drill.

There's some pictures a couple posts up on this page of other antenna's I use for flying around the yard or using my home internet.

The black contraption I used to mount my PS3 controller was an old Motorola Droid windshield suction cup mount that I hacked up extensively to make work... I heard they have a market ready version made by gameclip (gameklip?) Try googling I guess

EDIT:

HERE'S that gameklip... You buy a random cheap case for the nexus... Mount the gameklip to the case... And pop the case on and off for quick use with PS3 controller.
