hey all,

I was giving a broken a100 to take a look at. The screen completely turns white when I turn it on. is this bricked or just a bad lcd? If it's bad, do you guys know if i can just replace the lcd?
[Acer Iconia Tab A100] pio_masaki:
That's not a brick, its note likely a bad LCD or connection.

Digitizer is usually fused to the LCD, so you may want to check that before ordering a replacement.

[Acer Iconia Tab A100] Crusader01:
Hi pio_masaki! My A100 died too due to emmc failure. It would not mount any of the partitions. Would you recommend replacing the motherboard to one of these? Or you think these ones have the same emmc chip and sooner or later it will fail again? I'm just looking for alternatives at this point...
[Acer Iconia Tab A100] lotherius:
Chances are it will fail again, but for $44.95 maybe later rather than sooner?

I'm not sure what the actual percentage of failure on these is, but it does seem to be pretty high. I am still debating doing a motherboard swap myself, though I'm learning toward "no".
[Acer Iconia Tab A100] pio_masaki:
I firmly believe all a100s will fail at some point, so its a gamble. IMO replace it and unload it asap.

[Acer Iconia Tab A100] Crusader01:
I was leaning toward no too since I got a nexus but I was gonna give this to my mom if I could fix it. Also on eBay it says "refurbished" which makes me think... usually the emmc breaks on these motherboards so I wonder if these are updated ones or not. I might email the seller.
[Acer Iconia Tab A100] pio_masaki:
Refurbished means WiFi died and it got a new card or something. The emmc is not replaceable. The emmc was never updated, Acer never acknowledged they put a bad emmc in these, just replaced under warranty until it expires. Even better, some newer Acer units still use it and chances are they'll all die too.

Hmm that's not good. I might just forget about this little Acer then... Too bad its impossible to find a 7" tablet with front/rear camera, micro USB and HDMI output. Besides Chinese brands I mean...
[Acer Iconia Tab A100] pio_masaki:
Toshiba thrive has a 7" model with all that. I use the 10" model and dev for it. Acer had a winner and pissed on it and us for supporting the 7" market early on.

[Acer Iconia Tab A100] Crusader01:
Yeah you are right I forgot about Toshiba. But see if I was gonna buy a new tablet in 2013 I'm not sure if I'd get a tegra 2 again. Its about a 2 year old technology.
[Acer Iconia Tab A100] pio_masaki:
In that case Toshiba has the excite, tegra3 models that replaced the thrive. Better options out there, though, as its pretty locked up despite its gorgeous screen and hardware.

My tab got extremely slow, so I reboot it.. but it bricked.

[Acer Iconia Tab A100] pio_masaki:
May want to keep it, I've hit a dead end on the JTAG until I get hardware to work with, and I can't justify 2 or 3 hundred bucks for it at this point for reasons I won't get into right now.

donation

I live on a thousand dollars a month social security, and I can't afford to just give away a two hundred dollar tablet, even if it is currently broken. If I did that, I'd still have to spend ANOTHER two hundred bucks or so to buy a new one anyway. As I said, if there's a chance I'd get it back, I'd be happy to ship it, and wait.

Sorry.

In my /dev/block/ folder I've got mmcblk0p5 and mmcblk0p7 only.

I tried to make the missing partitions but I'm bad at linux (in fact I'm new to linux :mad:)
[Acer Iconia Tab A100] pio_masaki:
Thanks for the quick update, it looks like all of the partitions are gone, except maybe 5 and 7, which I have no idea what they are, they don't seem to be documented anywhere, and recovery doesn't mention what they are that I noticed. cat /proc/partitions does include them as well, though.

I've been talking with Morfic about this,and just sent him some updated information, hopefully with everything I've given him, he can create the partition scheme so we can attempt adb shell parted and recreate them all, if it works, then we can try to either install a rom, or just DD back in an image of the entire partition.
[Acer Iconia Tab A100] LeRx79:
Thanks for your help but I think my a100 is really dead :(

Good days;

I also have a tablet brick from yesterday. And I am very angry. Tape-worm the tablet with CWM and for supues the unblocked bootloader. Tape-worm installed this room http: // xdaforums.com/showthread.php? T=1574897 and empece to having problem with CWM, since not me leia the external card SD for what not podia to do backup, or to load a new rom. at the time I put to look and lei, that was a problem probably of compatibility of the card SD or that was returning to realize again everything the process of unfreezing of bootloader. and this way I did it. again this process, which was the same that it uses previously and I me work. Http: // xdaforums.com/showthread.php? T=1557445.

I restart the tablet, and from this moment, have the logo of green maple tree, and a phrase of red color that he says: " recovery verified failed .... " it does not start the tablet, and it does not also leave me to enter the recovery. if I try to enter the recovery this message goes out for me.

I have tried to install again everything across the PC, but the PC neither recognizes me the tablet, when I connect it to the PC, even the connection of the usb nor is heard, since this one does not manage to be ignited completely. And I am not going to take her to the SAT to whom receive from me 100 €, , Since for other 100 € mas I buy myself the new nexus. but it gives me great anger, because really I like a heap this tablet and it was going less than two weeks with her.

My A100 is a sad sight, piling dust on my desk. :(
[Acer Iconia Tab A100] pio_masaki:
Sad to say, that's not bricked, that's working as intended. If you have no nvflash no fast boot no adb there's really not much of a chance of anything being done since we have no boot loader key.

[Acer Iconia Tab A100] eww245:
Well, another victim of a brick here. Was testing AirDroid from my phone to the tablet. Using Dolphin HD hit the home button and it froze. Held in the power button to power it off and it's now stuck at the acer logo with no adb and no fastboot. Can't flash ICS through stock recovery, dead android, and the recovery has no way to select anything, power button doesn't select. /cache doesn't mount.

I was on a HC gen 2 before flashing the leaks then 014 posted by ZeroNull. Rooted, never updated to 037, not unlocked so no CWM or TWRP. Likely /data got corrupted while using Dolphin. I don't normally use Dolphin chrome was slow with AirDroid so I wanted to test other browsers. As far as I can see there is no way to unbrick.

Not asking for help here just adding myself to the list of broken a100s. Bought it in Feb so it should still be in warranty, I'll call acer tomorrow.

[edit] Actually I do have fastboot working, but it's useless being locked. continue reboot reboot-loader (only reboots to acer logo) ,getvar and serialno work.
[Acer Iconia Tab A100] pio_masaki:
Thanks for pitching in that information, sad to hear it happened, hope Acer takes care of it. Its way to common an issue to ignore I would think.

Oh btw if you have to box, could you put the manufacture date? Wondering if certain ranges are prone to it.

[Acer Iconia Tab A100] MegaDragonMan:
Can someone who has ICS give me a backup of the files that are in the /dev/block folder? Thank you.
[Acer Iconia Tab A100] pio_masaki:
Those aren't files those are device partitions, the way the memory is split up. Those partitions have files on them, but which do you need?

If you just plain don't have anything in /dev/block that's a bit harder to fix. I have images for cache and system but system is over a gig. I can make images for any partition but data will be extremely large as it'll contain internal SD too. Then you can use dd in adb shell or fast boot at the boot loader.

My intention is to copy those files using dd via adb and then flash a ROM. I can use TWRP file manager without problems and I can transfer files, but they will be deleted on reboot. So, I want to try this. I have only mmcblk05p and mmcblk07p.
[Acer Iconia Tab A100] pio_masaki:
I would use the aroma file manager I put up awhile back. Anyways I can't put up the files now no at home, but if you want I'll put them up when I get home. Its something I've wanted to try for awhile now.

You won't need to flash a rom if you DD my system image, it will already be there from the DD. All you need to DD is system and boot, after that it will attempt to boot. Even if data or cache is iffy

Taboonay ROM

Yes, the unlocked A200 bootloader from here

I forgot, the one with overclock functionality, black background with green accent, looks like CWM though

No, I did "Fix Permission" in recovery just because of curiosity...and it bricked

Yes, have tried replacing the recovery via fastboot, but can't read sdcard so I can't flash any flashable .zip from the sdcard

Built-in, didn't flash any custom kernel

I did select the overclock option, but it always back to 1 GHz on every reboot, so I think it wasn't overclocked.

An android robot lying dead with a red triangle in his stomach....

Hello,

Our A100 can't boot today. It just sits hung on the white Acer logo. Our A100 received the OTA ICS update last year and is completely stock.

When I try the recovery mode - holding down power button+up volume for 5 secs, the android robot appears with a spinning blue thing in his stomach. Next, the android robot looks like he's lying down dead, with a red triangle exclamation mark in his stomach. I guess that means he's really dead right??

Some questions:

1. Can I still recover any files or data from my device? (using a USB cable connected to a PC?)

2. Can I still send in my tablet for Acer to fix ? I still have my original receipt from Walmart. We bought it when it was first released at a crazy price of $328 at launch.

Any help/advice is most appreciated....
[Acer Iconia Tab A100] pio_masaki:
If its an emmc brick then anything on it is gone. If its under the one year warranty it can be sent to Acer, if not, then you'll need to replace the board yourself, if acer even accepts it they'll charge you more then it cost to get it fixed.

Tapatalked from my HTC DNA - Carbon
[Acer Iconia Tab A100] me4tux:
You mentioned it's emmc memory so I assume you are referring to the on-board flash memory? Okay. Sounds like the data on it is gone forever right? Is there another way to get it up to a state where the flash memory can still be read by an external PC.

NOTE: What's that tiny hole on the side that says "reset"? Can I use that to perform yet another kind of reboot?

I saw a few posts up that Acer is still repairing them out of warranty, so do we have a chance at all?

Ours is way past 1 year so the warranty has expired.
[Acer Iconia Tab A100] pio_masaki:
They may repair out of warranty but tit costs over $200 last I heard.

The pinhole is just a reboot button basically, it can also be used to triffer apx mode.

The only way to read the flash memory is via JTAG, however the emmc is damaged in some way, or corrupted, so reading from it is likely not possible.

Hi all,

i own an A101 and i was running unlocked bootloader with twrp touch 2.21 recovery + stock rooted rom ICS 4.04. its been without any problems for about 3 months till yesterday.

I gave it to my sisters around 1 months ago and still working fine until today i was at work and didnt know what they did, the tablet cant boot into android os.. its stuck the acer logo but i can still boot into the twrp touch recoveries. But then another problem arise when i tried to install from my external sd card in the twrp menu. its stuck on the internal storage option and cant tick or touch to external sd.

i tried wipe cache, dalvik cache and factory reset from twrp recoveries but nothing seems to work.

wipe cache shown successful at the top but the log file looks like this:

E:Can't mount /cache/recovery/last_log

what could be the problem? how can i resolve it? i cant even relock the bootloader since the twrp cant read the zip files in the external sd card

still have about 8 months of warranty there but i cant just bring in the tablet to acer cos its unlocked bootloader or can i??? or maybe any way to make it look like the normal acer without unlock bootloader?? what are the steps i need to do with my tablet to make it looks like stock standard?

thx beforehand for the help.

[MENTION=4757755]beckham_totti[/MENTION]

Keep powering it on and off until it goes blank, then send it in under warranty. Read back a bit and you'll see what I mean, but basically until the power led is on but nothing on the screen, that's finishing the brick. It may take awhile but it'll eventually die all the way, the boot loader won't matter and they'll just replace the motherboard and ship it back.
