Another person posted something re: their A100, and the symptoms were similar. I'm hoping someone has had a similar experience with their A500 and recovered. I have an A500 refurb unit, running factory ICS software (non-rooted) that is frozen at the ACER logo boot screen. Unfortunately, I have not had any luck recovering it, and mine is apparently out of warranty.
The issue arose, when I was trying to back out of a game that my son had started, and, once at the home screen, I started getting repeated program crash errors (i.e. Laucher has stopped working, wait/close, Agent Dash has stopped working, wait/close, etc). I tried clicking 'close' or 'ok' (can't remember exactly what the question was), and it ended up running through a list of apps that had been opened at some point or another, while continuing to comeback to the Launcher has stopped working error.
I tried powering down, then powering back up, and the Acer logo screen is as far as it will go. I have tried the hardward reset, and it apparently succeeds in Erasing User Data and Cache, showing the messages on-screen, but then freezes on the ACER logo.
If I try to boot into recovery an load the update.zip from the SD Card. It looks as if it is trying to update (upright Android bot with polygonal prism rotating in open chest, and blue update line below), then the screen flashes to a 'dead Android bot' with a red exclamation point above his chest. It looks like USB bootloader mode works, but I don't have anything on my PC to try and utilize that. Or, at least I'm not aware that I do. My hope is that, if anyone has had similar experience, then possibly, there is an issue with Acer's OS update (possibly due to poor memory management) that is causing corruption in the OS- maybe calling an erase memory sub-routine erroneously, and it is affecting the flash with the OS.
(Long shot, I know.) If so, maybe they would be willing to reflash the out-of-warranty units for free, or, at least, for the cost of shipping. If there are methods that anyone has tried successfully to remedy this, I'd appreciate any advice. If there are files available to load onto the SD Card or for use with the USB bootloader mode, I'd appreciate being pointed in that direction. I had the same problem with my Acer Iconia A100. I was playing a game I frequently played and then the tablet just shut off and wouldn't re-boot. Stayed stuck on the Android logo.
My A100 was running ICS non-rooted. I had to send mine in for repair and they replaced the main board, however I am still having issues with the A100 maintaining a wifi connection. This has been ongoing since day one. When I received unit back it had been re-set and I had to do all the system updates and when it was doing the ICS update the wifi connection was lost at 37% of the download. The tablet seems to be working o.k.
Now except for the wi-fi issue and I am planning to send it back since they did not address that issue as I had requested. (I don't even think they read the paperwork I sent in with the repair) When I called them to find out why the wi-fi was not corrected they said the repair order only stated 'tablet won't boot'. From what I have been able to determine from my short research on this topic. It appears that this has happened to hundreds if not thousands of Iconia A100s and A500s, maybe other models too. All indications are that unless you are under warranty, your screwed, the unit is a paper weight.
Acer Update Decrypter Executioner
I absolutely loved my Iconia A100 and was bragging it up to all my friends. Why buy a freakin iPad when you can get this sweet little 7 inch running ICS? Well, i guess I am going to have to find something else, Samsung Galaxy maybe? Very disappointed. 1-17-2013.same problem as the rest a500 frozen at ACER screen. Tried pushing the reset pin and the hard reset procedure many many times.starts to say it is clearing data/cache.but then goes to the ACER screen.
13 months old.and of course, out of warranty. It is completely untouched in terms of any kind of software adjustments and only downloaded apps from PLAYSTORE. 100% 'stock'. Has anyone fixed theirs or discovered a process to fix that they can publish? Thanks.Mike edited for privacy.
I am having problems adressing Windows Error 28 on this laptop for the device noted above. Device is identified with yellow triangle containing exclamation point I have attempted 'Update driver' with no success. I have attempted uninstalling the device and rebooting with no success. I have done several searches seeking a driver for this device but have had no success. The device itself appears in Windows Device Manager under 'Other devices'.
2 other items also appear in this group: 000eSMS/MMS Bluettoth Peripheral Device. Both of these are identified with question marks.
Windows is unable to update either of these 2 devices also. Windows 10 forums have been unable to assist with this. Any suggestion on repairing this error would be appreciated. Thanks in advance - Terry Davidson.
Hi - Thanks for your reply. I corrected the error with the PCI Encryption/Decryption Controller via this link I discovered after posting here: I followed your link and downloaded and installed drivers for both Atheros and Broadcom since Device Manager was unable to identify the hardware beyond what has been noted. The question mark remains for both of those bluetooth devices, but Windows says they are working properly. I'm thinking these devices may be for a USB dongle that I have since stopped using. Thanks for your help - I appreciate it!
