My update keeps failing. Is it because I have a custom boot loader?
[Acer Iconia A500] FloatingFatMan:
Very likely.
[Acer Iconia A500] drewlim:
Does anyone know can I get stock recovery back?
[Acer Iconia A500] FloatingFatMan:
Sure. Restore your backup.
[Acer Iconia A500] drewlim:
Problem is the custom recovery won't restore backups. Its able to make nandroids but can't restore them :/
[Acer Iconia A500] FloatingFatMan:
Well, if you try actually reading a few posts above yours, you'd see that people HAVE restored their recovery partition and been able to update, so it clearly IS possible.

Perhaps try the Acer Recovery Installer app, it supports the A510 now.
[Acer Iconia A500] drewlim:
Hey man how did you put the stock booloader back on? Im fairly new to rooting and I managed to install Thor's custom recovery but don't have idea how to get back to stock.
[Acer Iconia A500] NoThrills:
Could someone post the build number after the OTA update?

I've had Image: Acer_AV041_A510_RV12RC01_WW_GEN1 and Build: Acer_AV041_A510_1.044.00_WW_GEN1 since I bought the tablet and don't have an OTA message yet.
[Acer Iconia A500] grizou:
Just an update. During the OTA I did not loose root. However, I unlocked the bootloader with ./fastboot oem unlock and after the update it was locked again.

I didn't really have any of the problems above before the update other than hot right side, which unfortunately the update did not address. I am afraid this is a hardware problem :(.

Thanks man. Its really strange, I have read many reviews and forum posts, and there are some issues that only some people have, and other issues that everyone is having (like the warm right side)..

Some people report having random reboots, touchscreen not responding, freezes, etc.. But other people say its a great tablet and they dont have a single issue.. Who should we believe?

Its like some units were defective.. I think we should wait some time until all defective units are sold completily hehe.. I am not risking myself yet..
[Acer Iconia A500] FloatingFatMan:
How is a software update going to help with a hardware issue?

I get zero problems with the rest, It's probably you.

---------- Post added at 04:02 PM ---------- Previous post was at 03:58 PM ----------

9/10 of such issues can be resolved by doing a factory reset, which is something I ALWAYS do when I get a new phone/tablet/laptop (well, not a factory reset on the tablet, I just wipe and install vanilla Windows).
[Acer Iconia A500] skipped:
If you flash ICS for any other device, those things will probably occur, so, YES, it can be a firmware bug.

I dont have an a510.. I just read some reviews because I want to buy this tablet, and that is what some reviews say..

Edit: The reviews I saw were from amazon customers
[Acer Iconia A500] FloatingFatMan:
I've flashed ICS on several devices, no such problems happen for me.

The device runs hot because of insufficient heat shielding on the chipset. No software patch can fix that, it's just how it was designed.
[Acer Iconia A500] David Dee:
And that really sucks as outside of the heat it is an awesome tablet... Sound is great, very smooth, great with games, great wifi/gps reception, very comfortable to hold, more than adequate display...... But heat is a big problem, especially if one has young kids who like to use it.

Sent from my Desire Z using the XDA App
[Acer Iconia A500] grizou:
Hello,

there's a shell script in /etc/install-recovery.sh which is called on every stock rom boot. Might get your original recovery back.
[Acer Iconia A500] skipped:
So those issues reported by Amazon customers may be just bad luck, they got defective units..

I guess I am buying this tablet..

[Acer Iconia A500] rushless:
After having the A510 since Sunday, here are some personal observations:

Good

+Best built tablet I have used and prefer to the Prime due to the better grip and more comfortable to hold.

+The wifi is great and makes up for the gosh awful wifi range on the A500.

+File management is great and the large battery makes using and powering a USB drive practical. It is a good thing too, since there is no separate power jack.

+The display is great considering not IPS. I definitely notice better definition with this display over the 300 and Prime. Weird, since all are same pixel density.

+Like the iPad "3", the tablet will trickle charge, so handy if near a usb and do not have your power supply. Does not charge fast (very slow), but is better than nothing if trying to extend battery life with no power supply (bit by bit).

+I have noticed a few media and personal reviews claim the sound is weak. Seems Acer should have defaulted sound at better settings, since it is great when adjusted.

Bad

-Maps is an aggressive app that loads four times (at the same time) and is one the highest battery users (even though I do not use it). I have not had this issue with any previous device, nor any Android phone and I use Maps/GPS a lot with a phone. Something is not right here. I have now rooted the A510 and disabled Maps using Titanium. Though I have rooted all my phones, this is the first time I felt compelled to root a tablet, so I could disable Maps. No problem, since will not use the GPS.

-After concurrently downloading the GTA 3 data file and then playing GTA for less than ten minutes, the right side was HOT :eek: (same thing after the Acer 289mb update)

The temperature was not "Ooh, that is warm", but "Dang, that is hot!". I thought the Razr could get real warm at 117 degrees sometimes, but the A510 got to 125. That for a tablet that you hold EXACTLY where it is hot is too hot. Sure, you can use a case, but that only bottles the heat up more and does not seem to be a healthy thing for the chipset or the battery. My iPad "3" is cool in comparison.

Very frustrating here, since the tablet overall (sans the usb location) is FANTASTIC, were it not for the heat issue. I will mess around with it more, but I SHOULD NOT HAVE TO. Seems likely the A510 may see a lot of returns due to the poor heat dissipation design. How did Acer NOT catch this? :confused:
[Acer Iconia A500] FloatingFatMan:
How are you discerning this? Mine shows no indication of trickle charging over USB...
[Acer Iconia A500] rushless:
Multiple times I have had the tablet hooked up for data at less than 100%. After an hour, I notice about 2% increase. I have left the tablet to transfer gigabytes of comics and video (takes time) at about 85% and in the morning, it is 100%. Like the iPad, it does not appear to charge when the display is on.

Ditto for when at work. Since I have had the A510, I have not used the main charger unless down past 70%. Use it a lot too. Added: Well, for me I do, since also have the iPad. For the iPad, I have never used the charger.

BTW, I accidentally pressed thanks, but I am sure you have posted some things to thank :)
[Acer Iconia A500] mossief1965:
I've had the issue with Temple Run but none of the others.
[Acer Iconia A500] rushless:
I have had crash problems with FX Pinball and FPSe playing PSX games, but a reboot fixed the issue. No apparent bad issues (besides mega heat spikes) since then.
[Acer Iconia A500] AcerGamer:
The latest update for the a510 should have fix any problem like that. If you're still having the same problem then it might be your unit. Mine ran temple ran temple run fine before patch as well.

The only games I had problem with before patch was Shadowgun and Siegecraft, both game is running on the unity engine, so that might be related. After the new update though, both game is running at top notch. No more laggy controls.

[Acer Iconia A500] BethyM:
Did you adjust the brightness? I actually had to download an app to make it go dimmer for indoor use. The screen has excellent clarity even though its not IPS. I hope you enjoy getting to know it, glad to hear they are showing up mainstream.
[Acer Iconia A500] mossief1965:
I had rooted my tablet when I first received it and when I applied the new firmware today I re-rooted, however when I run titanium backup I get a message that "your rom is rooted but the "su" binary has non optimal access rights" It says titanium may be able to fix it but fails to do so. I there something I can do to solve this?
[Acer Iconia A500] 463nt_0ran63:
Yes you need to reroot again, there is a thread here: http://xdaforums.com/showthread.php?p=23285307 in which you will find a new script. I successfully rerooted mine today also. After rerooting titanium backup can fix the access rights
[Acer Iconia A500] mossief1965:
I have already rooted again and I do have root access (at least with other apps) but I am getting this error message from Titanium. When I ask Titanium to fix the access rights I get a message that it was unable to do so and I should root again but doing so makes no difference.
[Acer Iconia A500] farris:
I am very curious if it's hardware issue (touchscreen, freezes, etc) or software. Because it's good 9 out of 10 times, I blame the software. I hope for a update for this.

But yeah, it has a warranty of a year so when it's hardware that's not a big problem actually ;) :P
[Acer Iconia A500] aznmode:
Can you check superuser has titanium on the list. Try removing it and then run titanium again so it asks you to allow root access again. This might help.
[Acer Iconia A500] mossief1965:
I've done this but it makes no difference. Thanks anyway.
[Acer Iconia A500] jacindc:
I don't know if I'm just using it less intensively tonight, but my updated tablet has been on for a couple hours, and it's nowhere near as hot on the right side as it has been. Still warm, but better than before?
[Acer Iconia A500] 463nt_0ran63:
Did you use the new zip in the linked thread or the old one? I had to use the new one after that titanium could fix it. Btw the old method also gave me root but "not enough".
[Acer Iconia A500] Bøbo:
I have the same thing happening to me. I also had small issues with the touchscreen responsiveness but everything is good now.
[Acer Iconia A500] grizou:
I had the same issue. The following steps solved it for me. Open adb shell, remount system partition read-write, have the super user app re-install busybox, reboot.

Ymmv. Regards
[Acer Iconia A500] farris:
Hmm, still no OTA for me...
[Acer Iconia A500] lom4x:
Anyone else having instant reboot if you are switching Bluetooth off while the phone connected to the tablet?
[Acer Iconia A500] farris:
I just had a reboot when i received the xda notification mail :-P so annoying:-(
[Acer Iconia A500] plitshec:
I was planning to return my tablet due to the heat issue but read about the OTA update and decided it couldn't hurt to give it a try. After installing the update, it seemed to be running cooler for me as well. I didn't think it would be fixable in software, but it looks good so far. Good on Acer for the rapid response on this, though a change log would be good to clarify exactly what got changed/ fixed...
[Acer Iconia A500] lom4x:
Have you benchmarked your tablet before? As the obvious fix could be frequency limit. I'm also feel that tablet not so hot after the update.
[Acer Iconia A500] farris:
When did you guys got the ota update? I've received nothing yet, no updates for my tablet or it was already updated out of the store...

Besides, the free xda app for android is a bit useless on the tablet because i've no menu button :-P
[Acer Iconia A500] gaetanolip:
When does tablet comes hot? Only when playing games?

[Acer Iconia A500] Randomwalker:
Well, at least various system monitors report the same speeds as before. Scheduling settings also seem to be unchanged.
[Acer Iconia A500] lom4x:
Yeah, "world of goo" for me.
[Acer Iconia A500] aamir123:
The menu button should be at the bottom next to the hinge button, also if you haven't received ota yet turn on wifi. Go to settings, about tablet, and click system update. Maybe it'll work for you then. Let us know...

PS. Dies anyone know if we are ever getting our own forum?
[Acer Iconia A500] farris:
Can't find such a button, see screenshot. Also i've wifi always on but it says already up-to-date ( but i've never updated it)...
[Acer Iconia A500] aamir123:
I guys your right about the xda app. There is axda for tablets version you can look into. Also can toy verify if you're system info tab oohs like this? I haven't updated yet.
[Acer Iconia A500] farris:
looks like i've another version... see screenshot
[Acer Iconia A500] aamir123:
Can someone confirm if Farris has the updated ROM? I haven't updated so what I have is stock. Also I think you are outside of us? Maybe the updates only for us?
[Acer Iconia A500] farris:
I wonder what my version is. Maybe there's a special version for Europe...
[Acer Iconia A500] aamir123:
I notice the ww in your image name, maybe one for us and one for world wide? But maybe another person from Europe here can post if an update is available. Also if your rooted maybe you can flash the us update. But be careful
[Acer Iconia A500] farris:
I looked in the A500 thread and there's a PA_CUS version and WW_GEN so no update for me i think...

Top bad, i hate the freezes, restarts and touchscreen
[Acer Iconia A500] aamir123:
I'm sorter you have that problem but apparently update fixes most of that stuff. This is really a great device. Hope things work out for you.also why not contact Acer chat support and ask when an update will be available?
[Acer Iconia A500] rushless:
I downloaded the GTA 3 data file and then played GTA for less than ten minutes and hit 125 degrees. This was after the update. I see no improvement. The tablet is so nice I am trying to rationalize about the heat, but seems obvious Acer did a weak job on heat dissipation design and the heat is exactly where the device is held. Not seeing how this was missed during testing. Using (for now) my Thrive case (sold Thrive) and noticed that the display got very warm on the right and the heat was high again on the back right side.

I am a BB silver member, so still have about five weeks to decide. You know, if the 510 gets this hot, imagine the 700 pushing a lot more pixels. Yikes.

Added: I am going to test more games. I can say that CPU heavy apps like N64oid and FPSe do not make the device hot, so it seems it is the GPU creating the heat. 3D games or games that use GPU assets seems to get

it baking. Just a guess, since my "events" could be different from others. Also seems using wifi a lot with downloading adds to the heat.

Help need stock recovery a510

I put Th..rs recovery on my a510 by copying it on the sd-card and renaming it to recovery.img

Stupid me forgot to make a backup of the original recovery.

Now the OTA update won´t install.

Where can I find the original stock recovery?

I searched xda, acer and the web, couldn´t find it.

Can one of you guys please post the stock recovery?

PS I can only warn everyone to not flash Th..rs CWM recovery. It does not work! It does not flash .zip files, just jumps back to the menu. I really wish I hadn´t installed that sh...t
[Acer Iconia A500] David Dee:
I unfortunately am experiencing no improvement in the heat issue post update. The right hand back side is still a frying pan during 3D gaming and wifi use. I am also trying to rationalize keeping it as I really like everything else about the tablet, so tough.

[Acer Iconia A500] deviouskater:
My tablet gets warm and never burning hot like some have stated. All I can say is this tablet is great. I had the transformer prime and don't regret waiting 3 months for this tablet. Things that work great compared to prime.

1.) Wifi is amazing good

2.) GPS works great. No need for dongle. Which means turn by turn navigation works tethered thru Bluetooth for data. Don't need to use my phone GPS Ike I did before the dongle came out.

3.) Battery is well worth the little extra thickness. I'm getting way more then the prime.

4.) Speakers sound amazing. No weird mono sound.

5.) HDMI outputs at least stereo. The prime had mono output which took away from the experience

6.) The screen is crisp and clear. But maybe not as good as primes.

7.) The price is $100 dollars cheaper then prime if you price matched micro center.

8.) USB host works great. On the prime if you used the adapter the keyboard is not available unless u unplug the adapter.

9.) Everything worked out of the box.

As for the A700. I was considering waiting on it but then I thought if they upgrade the screen without upping the gpu to tegra 3 + it would be slower the then a510. Didn't want to wait till tegra3+ prob next year. A700 is going to be over my budget of $500 including tax. Plus 1080p on a 10" screen sounds waste of money. I remember when HDTV people were saying 1080p on anything less then a 46 is a waste of money.

Well that's my 2¢

Oh and check out Tablet talk app. Discovered it last night. Basically let's you receive your phones text messages and let's you respond over Bluetooth and or wifi. Well worth the 2.99. don't need to pick up my phone at home unless some one calls me .

A510 USB Charging

When the screen is off, the A510 definately charges. I was disappointed when I first got it since the manual says you can't charge it by USB. I just turned it off and it had 34% battery left. I plugged it into a usb cable that I use for my cell phone into my computer. Forty-five minutes later is was at 37%. So when completely turned off it will charge about 4% per hour via USB.

I then left it on, but turned screen off and plugged in the USB and it went from 37% to 39% in 30 minutes. So it looks like when screen is off it charges at 4% per hour whether turned sleeping or turned off. Not sure why they don't tell you that in the manual as most people plug in the USB and see that the device doesn't show that it is charging and assume it can't charge via USB.

Not too bad considering if you don't have a charging cable, you can get forty percent charge in 10 hours while you sleep.
[Acer Iconia A500] rushless:
The trickle charge is nice. Same thing on my iPad 3 and was not mentioned in specs for that either. As far as the heat, I have not been able to repeat the hot heat event. Seems the combo of wifi downloading and GPU usage is the combo that causes it. I played GTA, but nowhere near the hot of before.

If the heat can be kept at bay, this tab is a keeper. The trickle charge is icing on a tasty cake. I was thinking of getting the 700, but based on the 510, the 710 may get way too hot pushing all the pixels. There is a reason the iPad 3 has a new and bigger GPU.
[Acer Iconia A500] jacindc:
Yeah, the heat issue seems fixed for this non-gamer. Been on for almost five hours, can barely feel any heat except for the little bit on the side coming out of the HDMI jack.
[Acer Iconia A500] drewlim:
I cant wait for devs to put out optimized kernels and roms for the a510. My rooted galaxy nexus which has lower cpu and gpu feels way so much smoother/snappier than my a510 because of optimized kernels and not bloated roms. Battery life has improved significantly as well. The question is when...
[Acer Iconia A500] on8a:
I have the European/Middle East version on my tablet and got the OTA update a couple of days ago.

My build number is Acer_AV041_A510_1.072.00_EMEA_CUS1

Though I guess that there should be a fourth version around apart from US/WW/EMEA with Nordic as my tablet misses the Nordic languages which is common on the Android phones Nordic builds.
[Acer Iconia A500] grizou:
Hello,

You installed the recovery dd'ing

dd if=thor_recovery17_A510.img of=/dev/block/mmcblk0p1

If we inverse this command with dd'ing an untouched recovery image with

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

Than theoretically you have the original image.

Or would that just be too easy and I have proved once more that I am capable of making mistakes...

You might be right, but one thing I have noticed is that it seems that the scheduler no longer hangs to a certain frequency as was reported and excperienced by myself. Never had a hang to 1300Mhz since the update.

Also the scheduler seems to be a bit snappier in changing freqs and switching on/off additional CPUs, but this is only my feeling about my observations - nothing i could underline with facts.
[Acer Iconia A500] farris:
I talked to Acer and they said my tablets needs to be in for RMA because of the freezes and reboots, but I don't want to loose the devices for some weeks so I won't do that.

Thank you for your help. I installed Terminal emulator with root permissions. When I type:

Did you mean to run the command on the tab via Terminal emulator or some other program?

If someone could just post a backup of the stock Acer recovery. It can be made with the app "Acer Recovery Installer" from the Play Store.

Click yes, abort the rest of the procedure and please post the backed-up recovery here.

[Acer Iconia A500] grizou:
I've tried the Acer Recovery Installer. It says "Cannot identify installed recovery. Stock or Custom?" Are you sure the A510 is supported yet?

Have my /dev/block/mmcblk0p1 dd'ed to a file and can send it to you if required. It's 6 MB, the whole block device which you can ddback to your recovery image. Not sure wether I can attach it here. Let me know.

Hi, have sent a pm to you.
[Acer Iconia A500] Doolittle Duckbill:
FloatingFatMan said that Acer Recovery now supports the A510. Then again, he has made some other statements about the recovery that are just plain wrong.

I´m really not that knowledgeable with dd and loading that into the recovery image. Is it possible to flash the file with fastboot? Something in the line of

sudo ./fastboot erase recovery

sudo ./fastboot flash recovery newrecovery
