Yeah, it lasted longer than I expected it to. No, the warranty is out, so no repair for me right now.
[Acer Iconia Tab A100] Presko:
Yesterday i came to an idea... and was wondering isnt there a way to be made a aroma based live image to revive our bricks ... is it possible ?

I admit that they are going to be some limitations and etc. maybe but after all its at least an idea to use the brick as a HD photo frame instead of catching dust&rust :) my idea is somehow to bypass the falty emmc and everything to boots via the external sd with the help of a pc for first boot, sme kind of tethered boot like iphones?
[Acer Iconia Tab A100] pio_masaki:
Nope, the brick corrupts the gpt, so the partitions are "lost" and the system can't read them, or find them, and eventually the emmc just gives out completely taking the boot loader with it. The boot loader doesn't have the ability to boot from SD card anyways. Once this starts there is currently no known way to prevent it or use the device without a board replacement.

I really wish they would have followed the nook color with the recovery from SD card thing, that would be a life saber for sure and at least maybe allow some use of the system.

Some questions

Hi Pio,

A recent turn of events for me, my A100 apparently was still under warranty (but ends in August) and currently just underwent a board replacement.

I should have it back home in a few days time. Some questions that I hope you can help with:

1. How did you get your warranty extended from Acer? Since my repair was done so close to its end, will they extend my warranty. How do I request for it from Acer?

2. Once I have my Acer back, how do I tell if the replacement board will be free from the eMMC defect? Is there a way to find out without opening the unit?

3. What counter-measures am I able to perform to not end up with a bricked A100 again? Any tips to implement prior to begin using the tablet?

Many thanks for any advice.

Rgds

[Acer Iconia Tab A100] pio_masaki:
1. It was because of my received date, it was otherwise out of warranty. To late for you as they already repaired it. Some report getting it elevated may get the warranty coverage, but again as its repaired already, not likely.

2. There is so far only a single documented 8gb module, you most likely still have it anyways. There's methods to check in the thread and maybe in the first few posts.

3. None. Sell it and purchase something not built by Acer. If there were we would be using them already and Acer hasn't owned up or attempted to help or even tell us what's wrong.
[Acer Iconia Tab A100] jtcressy:
Purchase Date: Nov 2012 as a refurb unit from wally world.

Emmc failure, simply put. Just count me as yet another victim. Tablet bricked itself while I was in school. Device froze up, rebooted it, and got the error message boot verify failed. Went into recovery to find it couldnt mount many partitions, including but not limited to mmcblk0p5. Was running stock unrooted ICS and the mobo was replaced from a warranty repair only 2 months prior. I just wish there was a way to jtag it, but as i've read, the software needed to jtag the board is not available at all. I also wish we could just solder on a new emmc chip, but you still have to flash it with software which is impossible to get.
[Acer Iconia Tab A100] me4tux:
Many thanks for your advice Pio.
[Acer Iconia Tab A100] Snowers96:
People, i´m really scared with my tablet. I do not want to break it, and I see I have no choice to use it until there is not any solution has this problem :/ Is not there some way to change any componentso that EMMC fix this bug?

I am very new to modificacione Hardware, so if anyone knows any solution, could explain it?

I've been reading this topic, and I saw that some changed the motherboard of the tablet, but not if the end or not they have solved this.
[Acer Iconia Tab A100] pio_masaki:
The replacement boards have the same emmc so it doesn't "fix" it, just gets it going for a little bit until it happens again out of warranty.

Its a BGA setup I think, so replacing it is quite difficult if not impossible without the proper tools which people don't usually have laying around.
[Acer Iconia Tab A100] Snowers96:
And, there are people with the proper tools for this? I mean, someome in the past year, can fix the problem?
[Acer Iconia Tab A100] pio_masaki:
Yeah, namely companies the do repairs for consoles, you'll need a full on reflow station to even attempt it. You'll also need to source a compatible emmc module, not all will work. Once you find one, you'll need to find a seller that sells just one, and not 1000, then pay to have the old one removed, new one put on. It'll cost more then a new nexus 7 will.
[Acer Iconia Tab A100] me4tux:
Hi Pio,

Sorry, I don't mean to hijack the thread.

I just received my unit back from Acer warranty.

The booting looks different- first the single center Acer logo appears, next, there are 2 Acer logos appearing on left and right sides of the screen briefly' before it gets to the Android word logo. Not sure if something in the bootloader has changed.... anyone know?

There seems to be quite a few hw items replaced on my warranty claim although I didn't request for it -

1. Mainboard A100_8U NVIDIA TEGRA == so, how do I tell if this board replacement eliminated the eMMC defect?

2. LCD module A100 7.0 Touch Wifi

3. Lower case IMR incl. Camera LE

4. Cable DC-IN

I am not sure, given all these newly replaced (improved component??) modules, that my A100 is now worth keeping again? It really looks feel like a brand new tablet. I hate to sell it, if I got replacement parts which are improved LCD module, improved camera part, etc.
[Acer Iconia Tab A100] chicinwang:
I have recently purchased one second hand. So any and all mods are unknown.

Also before I procceed,I skimmed through the thread for this particular problem to no avail.

It powers on,blue light on power button.And will charge,no vibration on power up.No graphics on screen of any kind. Connecting to PC Running Ubuntu 12.10,Iget no vibrate nor sound from either tab or pc.Basically it powers on with a blank screen and usb does not work.. I have good idea it's bricked.Just wanting confirmation i suppose.
[Acer Iconia Tab A100] pio_masaki:
Yup, classic emmc brick, refurb boards aren't to expensive on eBay and may be worth it if you haven't paid to much for the a100 already.
[Acer Iconia Tab A100] chicinwang:
$30 didn't think it was to bad of a buy. May get a board to get this one going. Then attempt to reflow this one, found a cheap reflow oven build. Then finding a compatible emmc eventually. All for farts&giggles :D
[Acer Iconia Tab A100] pio_masaki:
Nah $30 isn't to bad for it, especially if you can get it going under $60 more. Have fun!

bricked A100 stocked at ACER logo

Good day.. Would like to ask for help... I have read several posts of people who encountered problem with their A100 like mine. When I was using it last week, it hang. Then I tried rebooting it, but after that, it cannot pass the ACER logo anymore. I've tried several solutions I've read from different threads/posts.. The problem is that my computer cannot detect my tab whenever i connect it even though I already installed the usb driver for it, which i downloaded from acer website. It has the stock ICS, already rooted using ICS_rooting_A10x_A5xx, this is the only modification made for my tab so far. I already tried pressing the power and volume button that shows that it's already deleting the userdata and the cache. I also tried entering the system recovery, however, I cannot select any one of the options shown on my tab. I also followed the instruction in the tutorial on how to unlock the bootloader, but, still unsuccessful. No matter what command i enter, it always say that its waiting for the device to connect... :( I don't know what to do anymore... Can I still fix this thing? Please help... T___T
[Acer Iconia Tab A100] chicinwang:
Sounds like it's bricked to me, I bought one used that does the exact same thing. Congratulations you know have a cool looking paper weight.

:banghead:
[Acer Iconia Tab A100] pio_masaki:
There is always a possibility of JTAG but you'll need to locate someone who can do it.
[Acer Iconia Tab A100] odin1120:
can i still fix this thing? or is there any thread that can help me with this. :crying:
[Acer Iconia Tab A100] pio_masaki:
Maybe JTAG, otherwise a new motherboard.
[Acer Iconia Tab A100] odin1120:
sorry for being noob... may i know what jtag means? this is the first time i've encountered that term... is it something i can do on my own? or do i really need to bring this at acer's service center.. thank you in advance...
[Acer Iconia Tab A100] pio_masaki:
Its a way to access the flash directly, no need to use the board its on, that would possibly allow a forced flash of the partitions back and maybe allow it to resume working. Maybe. JTAG refers to the points on the board used for it. I think I have pics of it somewhere on this thread...

And no, its not something most people can just do on their own, special equipment and software is needed.
[Acer Iconia Tab A100] chicinwang:
Arrghhh!!! Three flashes on a refurb. Annnnnd it's TOAST!

Purchased:Feb 2013

Bootloader:Unlocked

Recovery: TWP 2.2.2.1

ROM:Kebbersrom 1.6
[Acer Iconia Tab A100] pio_masaki:
I get that on mine but it runs just fine, strange huh? Figured used boards are a gamble just for this reason.
[Acer Iconia Tab A100] chicinwang:
Well I was hoping it was a fluke. I had actually flashed your carbon rom, but got all kind of FC's. Tried going back to kebbersrom 1.6. Didn't work, It went back to TWRP load screen after restore. It'll load BL but animation is the android. Snif snif atleast I had the forethought to get the extended warranty coverage with Wally-World.

Now just gotta make up my mind what to get to replace it. Unfortunately it wont be another A100 , though i do still have the otherbricked one.
[Acer Iconia Tab A100] pio_masaki:
That sero whatever 7" is getting decent reviews from thrive owners who got it, and for $150 its a decent little device, maybe something to look at. If I go buy another 7" new it would probably be that one, for me no external storage on the N7..2? kind of kills it for me a little, but that screen is tempting...

That FCing sounds like a dirty flash, it may not have mounted correctly even when you flashed carbon...
[Acer Iconia Tab A100] chicinwang:
Thanks for the input. I'm not sure though i may have jumped the gun. Early i tried a restore after the bad flash. I just done a complete reinstall of kebbersrom 1.5 got a BL but won't go any further. Any idea's? On my MX I wasn't as worried about doing multiple wipes as I am on this one.
[Acer Iconia Tab A100] pio_masaki:
Not really, I just assume its dead or dieing when those mount issues start up, I'd imagine this one here is gonna die pretty quick too.

You can try going back to stock and starting over again. Or maybe the EUU or whatever may correct it.
[Acer Iconia Tab A100] chicinwang:
Whew! (Wiping forehead) Did full wipes again, then reinstalled 1.5 and gapps. And it booted! Close call. Though with wipes/flashes it wont be long.
[Acer Iconia Tab A100] benpwarner:
Glad I found this thread. Purchased around February of 2012. I believe it was running the latest version of flex reaper rom, it is unlocked and on twrp 2.2.2.1. So my kids were playing9 it and it restarted on them and went into a boot loop. I rebooted into recovery and tried to restore my last backup up but I keep getting E: Unable to mount '/data' (tw_mount). I can't wipe data or restore or mount. I can't flash a new rom. I'm at a loss. Any ideas? Thanks

Edit: I found a way to reset data using the volume button and the rotate lock and now it's working again

That's not going to any more then your last suggestion. In fact that's going back a step. If you want a system.IMG I van make you one just fine, I can probably even build that recovery for you if you want, but fastboot will flash it just as well as a recovery will.

There's just no way yo fix one unless you go to extreme measures, replacement is the only current way to repair one of these bricks.

Sit, carefully think of what you are trying to do, then write it out in your native language. Then under that, your English version. That way the translation may go better. At this rate you've probably broken it in 500 ways, and I still have zero clue what you're even attempting to fix now.

[Acer Iconia Tab A100] pio_masaki:
What are you trying to do? I can't guide you if I don't one why you're doing any of this.

As its in this thread I imagine you have the emmc brick, if that's the case then no, you can't mount partitions, that's why its a brick.

Tapatalked from my HTC DNA - MoKee
[Acer Iconia Tab A100] pio_masaki:
I would agree, but those particular errors are from using a ROM zip like, say cm10, then using adb update cm10.zip, those are the errors you see from that. I think those zips require a different setup then our updater type for Roms zips, I'm not sure what exactly, I've never researched on that part, just experience seeing those errors using it.

Mate, I have no idea what's going on with your tab, or what it was you were trying to do. Nobody, and I mean Nobody, tries to re-assign their partitions.

My suggestion, and it's probably a good one... is to go back to a stock rom. Start over again. The only reason I have posted, is because you "reported" your post as "spam". I wouldn't say it's spam, but more so that you have yourself an issue.

Roll Back to stock. Am sure you a100 guys can do that.

[Acer Iconia Tab A100] pio_masaki:
Do you have fastboot available? If so, and you want to try flashing images directly, we can do that. I may hate myself for offering this, but it can be done, and I can build you system and boot images to flash, which what seems like you want to do.

That aside, if your partitions still refuse to mount, there's a bigger problem there.

Mine just went out too. Tablet froze midgame, rebooted and wont boot past the scrambled acer logo. I can access TWRP just fine, but it will not mount any partitions. Been reading through this thread, and it looks hopeless, but let me know if there is anything that can be done to assist!
[Acer Iconia Tab A100] Moscow Desire:
Correct about emmc. Been there, did that last year :(

We removed emmc cap from the boot.img and recoveries to hopefully avoid that mess in the future. At least on the 510 and 700 tabs.

Lately, seems a lot of A500/501 users been running into the same issue with emmc. Partition corruption. Sometime an RUU will get it back, sometimes they use a babsector to bypass/resize the boot partition.

On the 700/510 it was the data partition, and were able to re-map the partition, but lost about 13gb of a 16gb tab, so mainboard re-placement was only option.
[Acer Iconia Tab A100] pio_masaki:
Sadly we don't have the SBK so RUU isn't even an option for us, what we get is something else, the CAP erase was removed, and my old a100 bricked on a kernel without it :banghead:

Tapatalked from my HTC DNA - MoKee
[Acer Iconia Tab A100] Moscow Desire:
Ouch!! Well, you can join the other folks in the boat ;) Ours got bricked because of a faulty CWM when first released. (if a person doesn't own the device, they shouldn't release such things without testing)

pawitp in the 700 forums managed to get one users bricked tab back by re-mapping the partitions, but like I said, lost 80% of the sd space.

NVFlash probably wouldn't have helped anyhow.
[Acer Iconia Tab A100] pio_masaki:
Short answer, no.

You don't need to read all of the thread, just then first few posts. Acer repair or motherboard replacement is currently the only way to repair it at this time. Maybe jtag, or the actual emmc itself flashed and replaced by a shop someplace.

In my case it went out yesterday while trying to browse on the Internet on CarbonROM Linaro, now just like pirate.brian it hangs at the scrambled Acer logo and I can't boot into anything except TWRP 2.6, where it too can't mount any partitions (0 MB for internal storage and 0 microSD alike), was mostly working fine in the days before, no idea what's my next step if I can't mount either of those to push a new recovery (i.e. 2.6.1.0) or ROM to so that I can flash...
[Acer Iconia Tab A100] pio_masaki:
Did you read any of this thread? Its trashed, they don't usually recover once it starts. Flashing a new recovery won't fix it, neither will flashing ROMs. It can't mount partitions, so it can't run.

My acer has been a doorstop for awhile now. But can't recall if I had any replies the last I posted about my issue. I don't believe I'm under the same bricked category as everyone else here with emmc. The only sign of life is the orange light when charging. Then when you turn it on the light will turn blue and home screen button lights up. But no acer logo. Nor ever any back light at all. I just opened up my acer hoping maybe the LCD screen got unplugged somehow. (Cause that's what it litterly seems like) but nothing seem loose or disconnected inside. Unless I missed something. (First time opening it up.

Any ideas?

The last I remember, this happened out of no where. Hadn't flashed a rom/ mod or even entered recovery or fastboot in over. A week. Just one day the battery drained and wouldn't turn on
