[Q] Acer Iconia a100 stuck on acer logo, please help asap, thank you.

Hey guys, My acer iconia tablet was working fine since I bought it, then suddenly it was lagging, crashed, then I tried turning it on, it was stuck on the acer logo. I left it there for about 10-20 minutes, and it was still there. I tried hard resetting it, holding Power+Volume down, but that only brought me to this android guy lying down with a ! sign in a red triangle. Then , I left it alone for 5 minutes trying to boot it up, and it worked, everything was fine. I tried going into an app, but it crashed again then I tried to turn it on again after an hour, and it was stuck on the android logo this time. Now, here I am trying and trying, but its just at the acer logo. My mom is going to kill me if I tell her about this, so I need to fix it asap. I would greatly appreciate it, thanks!

It can't be fixed by anyone besides Acer, it has to be sent in. If it helps, its nothing you did, acer used a known faulty memory chip and it just randomly dies. Acer will repair it for free if it's under warranty.

Good luck to you. Mine just died for the second time today. I'll be calling Acer tomorrow. I have about a month left on warranty.

Acer Tablet
And what if I don't have a warranty? Hopefully there is another way. I am assuming that if the SNID number keeps saying it's incorrect, that the warranty is run out.. I bought it from someone so I don't even think there is a warranty.

Acer doesn't really care who bought it, just its warranty period of 1 year. Incorrect means incorrect, not that warranty expired, check for typos and using like a L for a 1 or zero for O etc.
If you don't have a warranty you will need to locate and change the system board yourself or have someone do it for you. No other way, board MUST be replaced.

Wow. I just entered the serial number in, and it expired a few months ago...
I cant afford to pay 100$ for a motherboard.. Im out of luck. I hate acer products -_-

[Q] Is my A100 bricked?

Can anyone help me? I installed a program called gallery refresh and it didn't seem to do anything. Then my A100 started running very slow, so I rebooted it. Now it won't come on! It goes to the ANDROID screen, and it's animated, but it just stays there forever. One time it started up after about 15 minutes but it went really slow then just froze. Now it won't boot up at all. Just the Android logo. Is my A100 bricked? I still had important information on there. Is there anything that can be done or can I save my data off the internal sd card??
Thank you.

Now it's stuck at the green "acer acer acer acer" screen. It doesn't seem to be doing anything at all.

It's worse now...
I read some instructions on another site to clear the Dalvik cache and I tried it. Now all I get when I turn on the A100 is a black screen. I think it's really bricked now.

The acer logo is back now. I accidently forgot to put the external sd card back in it. It now boots up to the Acer logos, but that's it.

Need more info, what rom, recovery, etc?

Stock ICS, rooted, CWM recovery.
I went into the CWM settings and told it to do a Backup and on the next blank screen, the android came up with a spherical thing in his tummy that's rolling about. I'm not sure what that means. There is no indication of how long the backup will take, or even where it's putting it, or whether it works at all. I don't know how long it lasts.

Does Android have a safe mode you can somehow get to?

Goto a100 general sticky section, there is a dedicated brick thread with some things to try.
Sounds like the good old emmc failure to me though, and if it is, everything is lost, data, motherboard, TOTAL LOSS.

Also, there is a difference between emmc failure or just bricking by say a bad flash.
Suggest reading the wealth of guides here.

Last thing you can try is booting back into recovery and try to adb pull off your internal SD. Not likely to work, but worth a shot. Stop rebooting and wiping it, you'll just kill it faster, wait until after you get what you can off of it.
Then do a factory reset. It'll likely just not finish or reboot or go to Andy on his back again, never know.

Now it won't work at all. I didn't do anything to it, just went to sleep and when I woke up it wouldn't turn on. Been on the phone with Acer. They won't allow me to send it in for repairs because I'm three months out of warranty.

That sucks, Acer probably put only a year of warranty on because of their stupid eMMC chip. Thank god we are moving towards eSata now. I'm hopefully buying a Surface Pro.

I think a year is the standard time for devices, though IMO once this defect became known they should have recalled or extended the period, instead they just replace it with the same buggy board and kick it back out to die later for good.

Yes, I was very peeved. Acer wouldn't even fix it for money. They said I could not send it in. Thankfully, my note program was synced to Google. I thought for sure I lost it! I was feeling sick about it all night. Today I bought a Nexus and it synced right back up. I was so relieved. It was by far the most important data on the device. So I'm done with Acer now. Hope my Nexus will be better. Thanks for your concern, guys.

Same here. But I got on with acer chat and got bumped up to level 2.and they are fixing for free and paying for shipping. Out of warranty since March.

Thank you so much for posting your experience with Acer! If I had not seen this, I would not have even tried to get service since my warranty expired Nov 2012! But I guess because my problem was the dead emmc issue, I got bumped to Level 2 support and they authorized my return/repair immediately, including sending a FedEx shipping label to send my tablet to them! (Still waiting on the email with the shipping label, but I expect it shortly.)
So if you have a dead emmc, contact Acer chat service anyway, regardless of warranty! Their Level 2 support hours are 8:00 AM - 4:45 PM CST, Mon-Fri. Just go through support chat and they will transfer you through!

[Q] problem with Acer Iconia Tab A100

Hello all!
I'm french, sorry for my English, I use google translation :s ..
I have a problem with my Iconia Tab A100, 1 week ago in normal use (no root or another have been made, everything is original, I'm running android ics) it is blocked, then s' is on again .. But it is blocked on the acer logo white x(
The warranty is finished for 3 weeks :'(
So I decided to fix it myself. I tried to put the latest version of ics on a sd card (found here http://forum.xda-developers.com/showthread.php?t=1591235) and reboot in recovery mode but I get the android logo with a "!" .. When I press the menu button (the house), but the recovery menu appears impossible to select with the power button. Yellow at the bottom, there are inscriptions (see picture)
So I tried apx mode and restore with EUUs (http://vache-android.com/?dir=Tablets/A100 found here). I found my cpuid thanks to this tutorial http://forum.xda-developers.com/showthread.php?t=1751978. But when I get the cpuid in EUUs it does not work x(..
My tablet is dead? There is a solution?
thanks!

Emmc is dead, sorry to say. Needs a new board.

Hard to say how much they are, if you get a new one it's more then the tablet is worth getting as a refurb, and used will likely hit the same issue pretty quickly. As it's out of warranty I would suggest selling it for parts and using that money towards something less likely to randomly die. Nexus 7 if no sd isn't a problem, galaxy tab 2, or wait for the next generations of 7" devices which is probably within the next few months.
I'm sure others can chime in on devices to get to replace it.
Tapatalked from my HTC DNA

ok, thank you for your information. I do not think succeed in selling this unit for loose parts passing through a buyer, I must pass by a professional. Could you indicate of sites able to redeem my Iconia?
Otherwise, you know other tablets including Dolby mobile?
thank you!

Touchscreen not working after 4.4.3 update

I was excited to see that one of my Nexus 7 tablets was getting the 4.4.3 update today. I started the update and let it go. When I came back I was at the lock screen. I only have the simple swipe to unlock. I couldn't unlock it at all. Held in the power button for several seconds until it shut off. Thought maybe something didn't load right. When I booted it back up, same thing. No touch screen.
Here is a little background. This is a Nexus 7 v2. Unlocked it and rooted it using the Nexus Root Toolkit version 1.8.2. During the process I did install the recommended recovery option. Everything worked great until the update today. Seems like I can't do anything. I can't use this toolkit to restore from the backup I made because I can't get into the tablet to turn on USB debugging or whatever it is asking me to do. I tried booting into recovery by holding the volume down and power button. The result was a picture of the android with a red triangle and an exclamation point. Not sure what else to do so I am posting this for all of you guys with more experience than me. Can anyone give me any suggestions?

Once you are back at the android lying on its back, hold down power and tap the volume up key, this will get you a recovery menu, from there you can try to wipe cache and dalvik, and if need be, factory reset.

Touch screen is still dead.
Thanks for the quick update. I did all of the above and was able to reset the tablet. Not I am at the Welcome screen and tapping the screen does nothing I find it hard to believe that the touchscreen died during the update. I guess I will need to look on EBay for some parts. Can anyone suggest what parts to look for? Touch screen digitizer assembly is listing for around $65.

I might suggest you open it up now (you're going to have to anyways to replace it), and make sure the cable is securely inserted.

Tried the cables...
I found a tear down video on YouTube and was able to disconnect and then reconnect the long cable that goes across the battery connecting the 2 circuit boards. I believe this cable is connected to the digitizer. I was hoping that maybe this would fix my problem. No such luck.
Here is my question. This tablet was purchased on EBay and was sold as a refurbushed tablet with a 90 day warranty from Asus. I purchased it about a month ago so I should be in the warranty period. Since I unlocked the bootloader and rooted it, should I even try to send it to Asus for repair or should I just spend the $65 and buy the replacement parts on EBay? Instead of just buying the digitizer, I was thinking I would get the combo digitizer and lcd screen since it would save me having to use a heat gun to unglue the screen from the digitizer.
What do you think would be my best bet?
Thanks to everyone for all your suggestions.

You can always unroot and relock the bootloader (you can use this to get it back to factory), if it's under warranty I'd go that route.

USB debugging...
Wouldn't this require me to have USB debugging enabled on the tablet? Since I went into recovery and restored it back to factory defaults, I can't get past the "Welcome" screen because I can't touch the screen. I am going to try and chat with the Asus support team and see if I can get an RMA. I'd rather go that route than take the whole thing apart myself. I like messing with computers but I don't like messing with phones and tablets. They are just too small and fragile for my unskilled hands. Thanks for your help. I will post an update if I am able to send the tablet out for repair.

It uses fastboot, I don't think it needs it (in spite of what the OP says). And if I'm wrong, the worst that will happen is it won't work. You will need the fastboot drivers correctly installed in your windows or linux environment though.

Thanks for the link. I ran the dead_nexus7.bat file since I couldn't turn on the USB debugging. It wiped out everything. I then ran the command to relock the bootloader. All set. Talked with Asus (web chat) and got an RMA number. They even sent me a FedEx label to use. Now I am more comfortable sending this unit back since it has been restored to stock and the bootloader is locked again. Thank you for all of your help.

Update to my issue...
I contacted Asus using their web chat. Told the CSR about my issue and confirmed my Nexus 7 serial number. They emailed me paperwork to take to my local FedEx shipping location. It happened to be our local Office Max store. They scanned in the bar-code and processed it. I got a confirmation email with the tracking number. This was around June 6th. They received it in Texas 4-5 days later (because of the weekend). I checked the status almost every day. About 10 days after they received it I saw a status update. They included a FedEx tracking number but every time I entered it into the FedEx website, it showed up as invalid. I gave it a couple of days and then called FedEx. They were able to track the package and it was delivered to my house in late June. All in all it took about 3 weeks but they did repair it. I thought they would have just sent me a refurbished tablet. They actually fixed my tablet because it still had my screen protector on it. Just wanted to update you with the good news. My son was so excited to finally get his tablet back. I wasn't expecting it to take so long but I guess I can't complain. It didn't cost me anything out of pocket even to ship it to them. Thank you for your help with getting everything back to stock and the boot-loader locked.
Tablet was originally purchased as a refurbished tablet from a seller on EBay. It was supposed to have a 90-day warranty from Asus. Glad they held up their end. It all worked out in the end.

[Q] Stuck at "erasing userdata..."

Hello,
Recently my Nexus 7 (2013) battery ran out because I forgot to charge it. Since then, it won't boot back into Android when it's turned on - all I get is the black screen with "Google" written on it. I have searched all over the internet for the past few days, but I'm unable to find a solution. I'm hoping that someone here can help me, because the tablet's warranty has expired and I'm completely out of ideas. Here are the things I've tried or noticed:
I can't boot into Android. The tablet gets stuck on the black screen with "Google" written on it.
I can access the bootloader and interact with the tablet via fastboot.
The bootloader is locked. Trying to unlock it via fastboot oem unlock displays the "Unlock bootloader?" screen on the tablet. After I select "Yes", the command line output on the computer shows the following output, but doesn't get any further:
Code:
...
(bootloader) Unlocking bootloader...
(bootloader) erasing userdata...
Trying to boot into recovery mode from the bootloader results in the tablet being stuck on that black screen with "Google" written on it.
I have removed the back cover from the tablet and reconnected every exposed connector. I couldn't take the battery out because I don't have the appropriate screwdriver. Doing this changed nothing.
Any help would be sincerely appreciated. At this point I'm worried that it is a hardware issue, but I'd like to exhaust all options before declaring it as such, as it would essentially mean the tablet is going in the garbage bin.

How long did you let it sit at "erasing userdata"?
I don't recall specifically on my N7 but I know when I unlocked the bootloader on my 2013 Moto X it seemed like an eternity, which was mostly because there is no progress indicator, it just said "erasing userdata" and sat there for a while. Probably like 5-10 minutes.

Well that is surely too long. Not sure what else to suggest. Someone else with more experience might able to help.. It sounds like your partitions may have been messed up somehow, which I have seen others post about recently with the updates. I'm not sure what causes this or if there are any fixes, but I know there are threads about people being stuck on the Google screen and having issues after the update to 5.0/.1/.2.

Hi,
i had exactly the same problem. I tried everything to fix it and no luck. I had to resort in sending it to Asus for repair. Unfortunately my warranty has expired. I just got a quote from them saying the motherboard has gone and it will cost me £250 to repair!!!!! I almost fell off my chair. A brand new 32gb tablet will cost be around £180. This is surely a joke? I will be giving them a call tomorrow to complain!
I hope yours is still under warranty because it is most likely your motherboard that has gone. I've read a few others having the same issue and its been the motherboard.

Thank you for your response.
I'm sorry to hear about what happened to you. I've been reading around and guessed it's probably a hardware problem based on other people's similar experiences. Unfortunately my tablet is out of warranty as well, and I'm definitely not going to spend more on the repairs than I would on a brand new tablet. I regret purchasing the tablet in the first place, I really expected it to last longer than a year.
If you can, please let me know what ASUS says about this, if you intend to call them. They don't have a subsidiary in my country, but if you get lucky, I might press my chances as well and perhaps I can get this repaired for a reasonable price.

Mine has lasted 5 years more but my Nexus 7 has ended its days the same way as yours. Stuck at google when switched on, and stuck at bootloader when triying to flash it.
Time to go, it seems.
