I would prefer dd. In Unix this is a common command for low level copying of raw data from A to B. dd if=source of=destination copies from if (input file) byte for byte to of (output file). File can be either a file or a block device or partition.

solved - getting back stock recovery

OK, I managed to get the stock recovery back and got the OTA update, here´s what I did:

- deleted the recovery.img file (containing thors CWM) from the SD-card

- in Acer recovery installer, checked restore previously backed-up recovery image (although I never made any back-ups)

- got the Acer update OTA and checked "install later" so that the file is saved somewhere

- checked in system setting to look for new update, plugged the device to A/C as advised and -VOILA- the update went smooth

A big thank you to Grizou for his help. As it is, I´m happy I didn´t have to dd because frankly, I´m afraid of producing a brick.
[Acer Iconia A500] grizou:
I'm happy you got it sorted.

I've resetted my tablet to factory settings but to no avail. Airport city for example is still not playable because buttons need to be tapped with two fingers. Is that the case with your tablets too?
[Acer Iconia A500] BENETNATH:
Hi, Some news from my side.. I had this new recovery installed. Two days ago, acer sent through ota their new release. Unfortunately, i did not allow the update, and failed during reboot. I suppose it was due to recovery modification, or may be that i had removed some acer bloatware. Anyway, i made a mistake by booting with vol down pressed, and forgetting i had a microsd card with an update.zip on it. This file contained the a510 rv12rc01-ww-cus01 It is booting but i think i won't get ota anymore, and it is really less stable..

Could anybody upload a file that i might boot as update.zip?? Anybody may have an idea ??

Thanks
[Acer Iconia A500] plitshec:
I just downloaded Airport City and played it for about 20 min, cool game! Sorry to report that all buttons in the game on my tab only required a single finger to press. I didn't have to use two fingers at all.

---------- Post added at 11:40 PM ---------- Previous post was at 11:28 PM ----------

I ran quadrant, Antutu and GLBenchmark before and after the OTA upgrade. I didn't see any major change in speed.

One thing that is confusing me is that CF-Bench is reporting about 6300 which is about half the speed of a Galaxy SII... the other 3 benchmarks seemed to match the numbers from mobile tech review, so I don't think the tab is actually running as slow as CF-Bench would appear to show. I wonder if I need to buy the full CF-Bench pro to get a valid test on 4 cores...

Update: Ok, just ran CF-Bench 2 more times and of course NOW it ran just under 12000. Thats faster than the Galaxy SII, but not much....

Boot loop

:confused:

If anyone can help me please, it would be much appreciated.

I made edits to the build.prop of my a510 and now it bootloops.

Current status:

- locked bootloader

- stock, but rooted

- bootloop prevents adb access

- Reset button, lock switch reset both failed to fix

I googled my butt off, but at a loss..

I think I need the "update.zip"

the recovery screen asks for when you

hold the vol + power.

Or is there is a way to flash a stock build.prop.

I don't know.

Any help would be appreciated, as previously stated.

Thank you.

Did you try hard reset? The same way as a500
[Acer Iconia A500] Ron1967:
Since a few day's the proud owner of the A510, after weeks of looking at specifications and watching many reviews online it was clear to me.

It would be the new asus tab 300T.....

My old laptop was not up to date anymore and i would have to make a choice, again a laptop or a tablet....

Finaly it was clear, for all the things i want to do on my laptop it was possible to do on a tablet.

So few day's ago i went to the shop to get the asus, hmm it was thin hmmm it lookt fragile .... despite my strong wish to get the asus i went for another round by all tablets in store...

T o make a long story short, my eyes fell on a brandnew iconia tab A510, never seen a review never seen specifications but man.....

Big battery

Gps

Usb possible

Tegra processor

Extra memorycard possible

Before i realised it i was walking home with the iconia towards my home....

What happened to me ????

And still amazing when working on my iconia,a smile when working on it and the story behind it.

I think the difference between the asus and iconia is minor but very glad with my choice so far.

Hope to read a lot here with also iconia owners, see you all soon.

My issue is the lcd density.

I was able to pull the build.prop out.

Amazingly, adb works in the looping.

But I lost root and cannot push an edited one back in...

I have been encrypting my Galaxy Nexus for a while, tried yesterday on the A510 and the same thing happened as with yours. Except it didn't boot the first time after the successful encryption. I managed to boot it one of 30 or so tries. Had to hard reset it like you did.

Problems With A510

http://www.youtube.com/watch?v=P4R5Inea-Z0

Here is a video of the issues I am having with my A510.

They seem to have shown up after I did the OTA update. (the one that changed the boot screen with the Olymic Sponsorship stuff)

Sometimes everything will work correctly and other times it wont.

I am a little frustrated.

It is stock, not rooted, and I did uncheck all of the boxes in the anti virus app.

Let me know what you think. I am going to try a master reset when I get home from work.

I have installed a screen protector.

-Jason
[Acer Iconia A500] rushless:
I would restore to stock and start from scratch. If it worked fine prior to the update, seems something did not update or override the original rom very well.

Have 280 apps on my A510 and did have to reboot the tablet once after updating. Some apps were crashing. The tablet has worked fine since then. There is also a touch adjustment in the display settings, but even on low, it does not perform like in your video.
[Acer Iconia A500] FloatingFatMan:
I based that on the devs OWN STATEMENT that it was now supported. Don't believe me? Go read the thread in the Apps section. Maybe this guy only tried the market version instead of the beta?

As for other statements I've supposedly gotten wrong, where?

[Acer Iconia A500] zaozaorama:
similar

I have similar issues, but everything was smoot b4 both the update and the screen protector, so I don't know if the problem is the screen protector or the OTA.
[Acer Iconia A500] BENETNATH:
seems many people have troubles after ota update...

has anybody a update.zip of previous version? to go back and wait for next ota update?
[Acer Iconia A500] mossief1965:
I am having similar issues but I have been blaming my skinomi screen protector as it seemed to start then, however the OTA came at the same time so that could be the cause too. The problem with the soft buttons / system menu doesn't seem to be an issue if I hold the tablet and use my thumbs, but happens if I put down the tablet and use my fingers instead but no idea why.
[Acer Iconia A500] zaozaorama:
About other issues:

- heat not so much even with games like soulcraft THD, dark meadow or GoF2

[Acer Iconia A500] siverson612:
I had the same issue after the update. I factory reset the tablet and it seems to be a lot better.....so far.

I did the factory reset as well. I seem to be a little better also. I am going to keep my eye on it.

[Acer Iconia A500] BethyM:
Just with reset button or a total wipe? I have the non-responsive buttons too, but only when flat.... weird!
[Acer Iconia A500] Jsunn:
Yeah, it is weird. We'll see if it fixes itself. It was a reset from the settings screen.

This may be an interesting "feature".
[Acer Iconia A500] farris:
Factory reset made it worse for me. It takes 2 seconds for the tablet to come out of standby/show up lockscreen.

When I press the button, screen stays black, after 2-3 seconds screen shows up. When I restart he tablet, everything is fine.. but after 5 minutes it's back again.

Beore factory reset I didn't had this problem. Still Airport City problem and still flickering screen and stuff.

No update for the WW_GEN version yet so I can't blame the update.
[Acer Iconia A500] BENETNATH:

is there anyway to get a firmware to flash as an update.zip, from the 'before OTA' A510 ?

[Acer Iconia A500] mearoth:
Has anyone tried to tether via bluetooth? I am currently not 100% sure if it's a problem of the A510 or of my phone (running CM9 there) but when I try to set up the link with my phone the dhcp on the A510 times out. My laptop can on the other hand connect to the phone and receives all dhcp information.

OK when u are root you can try this on a terminal to access the internet:

dhcpcd bnep0
setprop net.dns1 8.8.8.8

but the problem is that this only enables the internet on linux level. Android does not check this and all google.services will not work.

I have no workaround for this yet.

Has anyone else the same probs?
[Acer Iconia A500] rushless:
Looks like the T300 got a forum and we seem treated like wicked step children ;) I hope this is a joke for the short term.

As far as tablet behavior, mine has 280 apps and seems stable after the update. I did have some app crashes, but they went away after a restart. The only app issues I have now are ones known to be iffy with ICS. My tablet is rooted (after update) and have Maps and the virus app frozen with Titanium. I will not use Maps much if ever on a tablet and if I do, I can simply unfreeze it. Maps loads four places in memory and tends to be the highest battery user (when low use or idle), even though not using it. Froze it.
[Acer Iconia A500] deviouskater:
I believe its something to do with android 4.0. Install PDA tablet. And on your phone the partner app foxfi ( if you have sprint grab from amazon app store). Works fine. But doesn't sync Gmail, talk and play store. Everything else works. Maps latitude internet
[Acer Iconia A500] deviouskater:
When trying to figure out the sleep of death this happened if I did the hard reset with power + volume up with lock screen back and fourth. It went away if you do a factory reset from the settings option in back up and restore. When laying flat its not grounding or something which is why I think touch sensitivity is weak. My sleep of death went away with ota but touch sensitive I believe went down. prob there will be an update to fix it . Mine is not as bad as yours .
[Acer Iconia A500] BethyM:
I know :( Guess that Best Buy ad carried some clout. I dint think we an do much but +1 that thread and be patient... I agree about battery too, seems much better after update. Now if only we can get the soft keys to work when its laying down :-)
[Acer Iconia A500] mearoth:
Thanks for the tip, but Gmail and especially Talk are the apps I really want to be up and in sync. I think I will try and have a deeper look to the system later.

Meanwhile I have noticed that after disconnecting from the BT device the whole BT stack seems to be unstable (cannot connect to anything after that). Only a reboot fixes this.

Hopefully Acer will also have a look at this or we get some devs to port a custom ROM (I really would if I could but as of now I am far away from the knowlege needed to port and build custom ROMs. I currently try to set up a build environment but have not come far jet - also spare time is a big issue)
[Acer Iconia A500] 463nt_0ran63:
Hi try to set the display sensivity to "medium" in the settings and this "not reacting" of the touchscreen is gone for me. But it wasn't that worse like in your video.

Some other question. A few pages ago someone mentioned that there is a sea app for tablets (with menu button) is this the premium xda app? Or is there a free variant out there?
[Acer Iconia A500] farris:
Only the paid HD app :)
[Acer Iconia A500] deviouskater:
Only way to get those working is using your phone as a wifi hotspots from my test. I'm running CM7.2. I get reboot when disconnecting Bluetooth from phone. I wonder if the prime has this problem. Doesn't matter I'm not going back to it but I wonder if its an issue with android 4.0 or Acer software coding. I can't remember when I had the prime on honeycomb if talk and gmail work. Didn't get to test on ICS because I returned it before it came out

If you want something for SMS forwarding and replying look in the market for tablet talk. Its awesome. Practically don't have pickup the phone when at home.
[Acer Iconia A500] grizou:
Get reboots too when disconnecting from bt. Shared internet connection over bt is not working at all.
[Acer Iconia A500] DemonRage:
I own the Acer Iconia A510 for a week now and it works just fine, however there are 2 occasions where things went wrong. Both times it was after I updated some apps with Google Play.

This is what happens in details in such case:

The first thing I notice is that when starting up apps, the apps won't load. It seems that only the background color shows and sometimes the title is shown.

At this point I can still switch back to the home screen (by pressing the home button) and try to run other apps, but they too fail to load. Pressing back doesn't help btw.

Another thing I noticed is that the clock doesn't update. The wifi icon does and the tablet is reachable from the network.

Turning off the tablet is now another thing:

If I get the shut down dialog when holding the power button for 1 sec, the shutdown process locks up. The screen does go off, but the tablet is still shutting down. (pressing the power button might turn the screen back, showing the "Shutting down..." message)

If I hold the power button for 5 secs, the tablet is forced off but problems worsen after booting: after a little while the screen becomes unresponsive and random reboots might occur.

Only when pressing the reset button with a paperclip removes its "bad state", possibly because it will do a cold boot instead of a warm boot when pressing the power button?

I think, in my case, it is a software problem. I suspect things might become corrupted (maybe in the cache?) when some app is updated, causing instability.

Note: I didn't receive the OTA update yet. My versions are the following:

Kernel: 2.6.39.4+

Do you have the full body skinomi or just the screen? i have the full body and am wondering if that has anything to do with it?

-Jason
[Acer Iconia A500] mossief1965:
Just the screen protector. I like it but still wondering if it's the cause of the problem
[Acer Iconia A500] Randomwalker:
Well, the actual retail price for the A510 in Europe is 399 EUR. But since it is mostly out of stock some retailers apparently try their luck w/ higher prices. You can probably expect the same for the A700.
[Acer Iconia A500] aznmode:
Sounds like you guys have the grounding issue where you have to hold the tablet for the touchscreen to work right. This was the issue with acer a100 too. If you're charging it won't have this issue either. But its good that it only happened after ota so there's a big chance it can be fixed via another OTA. Just need to bring this up to Acers attention so they can get the ball rolling.

A good utility to test screen sensitivity is an app called TouchUtil. It'll trace your finger when you run it across the screen and you will see the trace break if it loses connection with your finger. Then test with 1 hand holding the tablet or while charging.

Here's a video I recorded with the acer a100 issue

[YouTube]YrDXfj6TchM[/youtube]
[Acer Iconia A500] deviouskater:
I noticed also everything works whole lot better after I plug it in for a few seconds on the charger. Im typing write now, not holding it and unpluged with no issues. Its after I either reboot or shutdown the sensitivity goes down but once I plug it in and unplug its fine.
[Acer Iconia A500] BethyM:
Is there anyone experiencing the touch issues that did NOT recently install a screen protector? I have the skinomi wet.... just wonder how much of a factor it could be.
[Acer Iconia A500] acme anvil:
Only certain apps I have found have issues. It isn't a consistent issue as far as I'm concerned. I do not have a screen protector.
[Acer Iconia A500] eman01:
Same thing

Amazingly I had the exact same experience. Put the Skinomi on about the same time as update and definitely noticed an intermittent problem with touchscreen response, where I had NONE before. Wondered which it could be, but thought the odds favored the update. With others reporting issues, still think that's most likely. Hello Acer, anyone listening?

By the way, how did you like the Skinomi? I personally was (and am) dissatisfied. I have used multiple different brands of screen protectors on different phones, and though they can be touchy to apply I haven't had any significant difficulties. With the SKINOMI Dry Tech I ended up with multiple bubbles that I simply could not get rid of. Yes I did use the small smoothing device to no avail. Very unsightly and frustrating. (As a newbie please forgive if it is not appropriate to ask about a product in this forum. Since the product was mentioned in a post I thought it would be OK to inquire about it in a response. If not, please advise. And please spare the sarcasm/vitriol that seem to plague some posters. Not sure why that's ever necessary.)
[Acer Iconia A500] BethyM:
I didn't get the dry tech, but the wet one. I always have issues with the dry ones and thought I'd see how this went. I am reasonably satisfied with it. I prefer the glass but prefer a scratch free screen more! The skinomi fit is excellent and I managed to get a decent install.

I am thrilled with how much more stable things are since the update. They were good before, but now its great.
[Acer Iconia A500] pdagal:
I don't use a screen protector, but I've noticed since the OTA update that the display sometimes is less sensitive to touch, regardless of which sensitivity setting I select under display settings.
[Acer Iconia A500] farris:
I also have the touch issues without screen protector..so it's definately a software issue. No OTA yet.
[Acer Iconia A500] mossief1965:
I have the wet Skinomi and to be honest I'm happy with it. It took a few goes to get it right but it's pretty good now, no bubbles at all. I had a dry apply protector on my galaxy s2 before and had to get rid of it a as I couldn't get the bubbles out.

I just had a brief look into the euro file and it seems to already contain the new files from the last OTA. Since I have no experience in ROM cooking (although I would really like to) I will not risk a brick and will not flash it this time.
[Acer Iconia A500] BENETNATH:
yes,

but as i don't have a good recovery.img, i can't flash that..

anybody ?

---------- Post added at 05:12 PM ---------- Previous post was at 04:49 PM ----------

can you share this file please ?
[Acer Iconia A500] grizou:
Will be a pleasure. However, since I have no idea how big the recovery image is I had to dd the whole block device into the file recovery.img. Has the advantage that everything will be there but also has the disadvantage of wheighing 6MB. Just let me know where to send that file. You can also pm me.

Regards
[Acer Iconia A500] BENETNATH:
mediafire is okay

how did you get the img ?

cat /dev/block/mmcblk0p1 > /mnt/sdcard/recovery.img

??
[Acer Iconia A500] grizou:
The file is extracted with the *nix / Linux command dd

dd if=/dev/block/mmcblk0p1 of=recovery.img

It's basically a low level byte for byte copy of the recovery block device mmcblk0p1 into the output file recovery.img

'if' in the above command stands for input file and 'of' for output file

Will send you a pm with dropbox link

Regards
[Acer Iconia A500] BENETNATH:
thanks,

i saw the difference between cat and dd, but basically same thing yes :)
[Acer Iconia A500] grizou:
To write the file recovery.img to your tablet is

$ adb push path_to_file/recovery.img /sdcard/

$ ./adb shell

shell@android:/ $ su

at this stage you should have the # prompt and than you need to remount your file system read-write with the command

shell@android:/ # /system/sbin/bb/busybox mount -o remount,rw /dev/block/mmcblk0p3 /system/

Now you should be ready to copy it with

shell@android:/ # dd if=/dev/block/mmcblk0p1 of=recovery.img

Hope everything goes well

Cat is meant for concatenation, it's meant for merging multiple files together.

Cat file1 file2 > mergedfile

DD is meant for proper low level copying of data as such for turning a CD into an .iso for example
[Acer Iconia A500] rushless:
I was going to post that based on forum traffic, there is not much interest in the A510 so far, but seems there are not many units out there to buy in the US and the only little stock out there is through Amazon channels.

Best Buy does not know when they will get more. Perhaps they only shipped a small volume and we really ARE guinea pigs for a soft launch before the Olympic marketing push? That would explain the quick stock update. Perhaps they think they can manage any issues through updates?

Still say the heat displacement design is less than good..... I wonder how hot the 700 might get? Yikes on that right hand.
