Default Another bricked a500...

Apologies for yet another thread. I've been through every "unbrick" thread and still not able to boot the tab. I'm starting to think it's time to recycle the thing.

So, I picked up my tab one day and it had powered off (bone stock on the latest OTA). Tried to boot up and never got past the Acer splash screen (multiple attempts). Tried to reflash via the sd card, and it failed. Now it only boots to the dead Android. Try to flash another rom (these are stock releases) and it hangs for over a day without completing. Now it won't get past apx mos, black screen with a power light. Tried to flash via nvflash using several automated methods, they all fail complaining of various errors that seem to be related to bad partitions. I run badblocks and get errors. Now, having gone through everything short, I go to euu. That also hangs on copying the image. I'm out of ideas. is there something I haven't tried, or am I likely dealing with s dead tab at this point?

Pretty much the same thing happened to me last night I stayed up all morning trying to fix it but I'm beginning to realize it's probably something in the hardware.. Odd there so many all about the same kind of time.. Mine was rooted and the only thing I can boot to is the first skrillax boot loader screen, or Acer screen..depending on what I did..guess its Tims for a new tab..any suggestions? Lol

I guess we can take the guts out and make them into picture frames?

I did the fix my Acer thing from the Acer website found out mine is out of warranty for sure but they got back to me with an email and a phone number and I called and talked to a girl who told me it would be 200 and $49 just to get it in the door for a repair. Needless to say I bitched and moaned told her I was going to throw it in the garbage and she is now sending me a label for FedEx to ship it and they will look at it hopefully they will fix it possibly for free now lol so I'm going to be sending it off when I get the label. I've tried just about everything and it seems mine just isn't recognized very well by the PC. I wonder if I have the correct drivers

This is what I'd do, and this goes for anyone stuck on the acer logo or otherwise soft-bricked.

Run babsector.rar file.
This is the ONLY file that will give you an error that can be troubleshooted. NONE of the auto tools or the manual nvflash method will do this.

Once babsector has run, post the output and we can tell if its the dreaded hardware fault or not.

Download and instructions here http://forum.xda-developers.com/show....php?t=2049778

A great guide by kaijikun here http://forum.xda-developers.com/show....php?t=2450119

If you get stuck with the black screen with the power led light ON.
Hold the power button for 5 secs until it goes off.
Re-enter apx mode manually (i.e. this means using the buttons, don't use the auto tools, it won't work)

It also goes without saying, you need the acer drivers http://support.acer.com/us/en/produc...1&modelId=3851 and the drivers from the android sdk, you can download a mini zip here https://www.dropbox.com/s/x98233x397...ni_sdk_adb.zip

If you don't have your CPUID, there's no way of unbricking.
If you don't know what a CPUID is AND can still boot, read this guide here http://forum.xda-developers.com/show...1#post25429111.

If you cannot boot and don't have your CPUID you need to recover it using Linux, see srbeens guide here http://forum.xda-developers.com/show....php?t=1751978

Just to say, the whole unbricking process takes some time....mostly downloading everything you need. You will also need a fully charged tab, you can sometimes use 40-50% of your battery doing this. To be safe connect your charger and leave it there till you are done.

The other thing is your PC OS...there has been mixed success with win8 and 64bit. FOr best results win7, vista and xp work best. If you are linux savvy, you're in luck, no driver issues at all with this OS!!!

The only way you can not restore your tab to fully working order is if your tab has the faulty memory chip. And the only way to know if this is the case is to run the babsector.rar file.

Yeah same thing happened to my A500. But downloaded 4 files Because there was 4 to choose from.

I renamed the file, eg filename.zip, to "update" with no extension. Copied to a clean micro SD. Inserted the SD card. Held the volume down and power switch until tablet vibrated and toggled the screen lock switch on then off. Then sat and watched. The whole process can take 30 minutes and for a long time it seemed stuck at about 25%. I decided to wait and see. And it all came good.

My A500 was stock no root. Still is and seems to work better now.

Default Same thing happened to mine

Exact same thing happened to mine. No recourse since mine was out of warranty but I complained about it on an Acer Forum and on their facebook page and within a couple of hours I was contacted and instructed to mail it in. I had to pay for the shipping charges there (like 12 bucks) but they shipped it back on their dime and it was fixed. From shipping to them to getting it back was about 2 weeks. I was ready to swear off Acer forever but they manned up and fixed something that was obviously a widely known defect since it's happening to many others.
