Hi all,
I thought I'd consult the brains trust to see if anyone thinks this is salvageable. Was using my A500 about 2 hours ago, suddenly the screen powered off. Thinking nothing of it, I held down the power button to restart it. When powering back on, nothing appears to happen except for the power button lighting up. No screen on, no vibe, nothing except the power light on.
Tried power cycling a few times to no avail. Tried the reset button. Tried the Vol+ Power and Rotation switch reset. Nothing.
Out of morbid curiousity, I plugged it into the PC and switched it on and I get an APX driver being installed. So, clearly something is happening here.
It has done this once before and came back to life of its own accord very shortly afterwards, this time it's been dead for quite some time.
Any suggestions? It's well out of warranty now, so I doubt Acer would be interested in it at all.

In the Dev threads, or possibly Q&A, there is a thread called "stuck in APX mode". In there I believe are some steps to see if you can recover.
But, if you're in APX mode, you could probably try NVFlashing the bootloader and recovery the old fashioned way manually.
But look up that APX thread first. Will probably have the answer. I'll see if I can find it in a little while, if you don't find it first.

Thanks MD. I looked up the threads you suggested, and after a lot of screwing around I have installed the APX drivers and used blackthund3r's APX Flash Util 0.3 (The link is broken to the current version) to attempt a recovery of my tab.
Its now sitting at an Acer screen, "Entering Acer Download Mode" while the flash util is sitting at:
Nvflash started
[resume mode]
It's been there for about 10 minutes now, no progress to report. Is it worth just sitting it out, or now that the damn tab shows SOME signs of life, can I just restart it and reset to factory?
And then most bizarre of all. I declared no progress, rebooted it. It went back to APX mode.
Re-ran the blackthund3r tool, it didnt do much so I bailed that. Restarted tab and attempted to load recovery (vol + and power) and it booted normally.
What the hell...

erm for now i would make sure you have all backups of data, cpud etc,.. just incase. you can just sit em on your computer i always try to keep a nandroid of all 3 of my devices each month or so.:good:
edit: and of course keep the link for the thread MD recommended.
Gee. Sounds exactly like mine....
The only thing I haven't tried is an update .zip, but I don't hold out much hope.
Considering parting out at this point....
Yeah, I dont have high hopes that it will last a whole lot longer. Up to this point it has been running Acer OTA updates only, no custom ROMs and no root.
I restarted the tab a little while ago and it went back into APX mode again and stayed there. Some more furious button mashing and attempted restore-mode boots, and it booted normally.
I made the point of wiping it this time using the Vol+ & Power & Rotation Lock trick and its been ok so far.

I have a cousin in Jamaica. She might possibly help (chicken foot and some frogs blood...voodoo you know)
Here's What I think.
You got some corrupt data or a partially bad devblock. This might explain the strange behavior on boot.
Like the tab really doesn't know how to boot.
Personally I would do 1 of 2 things at this point. Either;
1. Root that thing, and try running Timmy Deans root back to 3.2. This should reset your partitions back to normal. Then work your way back to an ICS rooted, Bootloader, and custom rom.
2. Leave it alone, and don;t turn the tab off. Clearly some partitions are messed up at this point. The toggle of the lock usually wipes user data. But the core issue is still there.
If it were me, I would pull out the nuclear missile and go for it all.

Tried the update.zip - nada
Tried timmiedean yesterday, went into Acer Download mode OK, failed....
If dolps is like mien, the first time he tries to go into recovery, it will crash again...
It's baaaack!
Tried blackthunder flash again, failed.
Went to turn off to get out of APX, and it booted!
Now boots, boots to recovery and boots to primary.
I have no explanation.
We will see.
I am suspicious....

I told you maaaannnn, go see me cousin in Jamaica maaaannnnn. She do some good things you see
Glad it's running again.

First, is this a SOD?
I can kill it by booting into recovery and get it back by using Blackthunder flash tool to go into APX and letting it sit for 20 minutes or so. Close the program, unplug, reboot and it is back. I would like to use timmiedean (td) and go back to square 1, but it fails at the image detect ( displays ICS 4.0.3 Civato as the current image, a red X for the new image). Has td been proven to work reverting from ICS? Will a boot recovery reflash and a new ROM flash solve this? Is there another way to get out of ICS back to HC?
Any suggestions/comments welcome!
EDIT: I flashed FLEXxx V4. Shut it off, problem still there....
Really frustrated. Trying to use the timmiedean tool, but it requires that the unit be shut off in the middle of the process, which kills it. Does anyone know the whereabouts of the blackthund3r revert tool, or the .apx package for his flash tool. I can't find it...
I'm done with this one. On Ebay for parts.... GONE!!!
Have an A100 now, rooted, unlocked,. on Relix
1 more A500 coming next week
I got in an A500 that had a weird yellow icon in the upper left. I wish I would have paid more attention to exactly what it said, but it was a small yellow icon, squareish and, to the best of my recollection, it said something like "NO FILE SYSTEM" or something like that.
Anyways, I followed a thread that I started where Moscow Desire helped me a LOT..
http://forum.xda-developers.com/showthread.php?t=2131327
And was able to obtain my UID and SBK (thanx MD!! ) and went about trying to resurrect this A500..
I was able to get a bootloader installed... A black screen pops up at boot with
SKRILAX_CZ's bootloader v8
Booting Primary kernel image
But then it just sits there at the silver ANDROID screen. The ANDROID will blink a couple times and it shimmers, meaning it is not frozen. But I have left it at that screen for 10-20 mins with no change..
I have tried putting on various update.zip files but it either immediately pukes with a dead ANDROID or it just boots to the same silver ANDROID and sits there..
I have been able to boot into recovery once, did a wipe and reset and then it just went back to the silver ANDROID screen...
Any suggestions for what I can try next??
Thanx
Update info on this...
I have a working A500 so I loaded up PUB RECOVERY and did a back up of that A500 onto an SD card thinking I can simply RESTORE it to this one that is puking at boot...
I got an error message saying it couldn't format or restore /data.. I did an ADVANCED RESTORE and did each section one by one, /flexrom etc etc.. Everything copied over except /data...
Does this mean the partitioning is frak'ed???
Success!!!
I guess I was doing the right thing, but just needed the right combination of tools..
I used Black Thund3rs' APX Flash Tool and downloaded Bundle #11 from his "Bundles" Library..
Everything installed and, upon rebooting, it booted up fine..
So, woot!! Good to go!

Was using tablet and just playing a game -- tablet reset, robot with ! showed up.
After that, reboots bring me only to the Acer screen.
I can do the VOLUME UP + POWER -- vibrates, powers up, toggle the switch, let go of power button and it does:
ERASING USERDATA...
ERASING CACHE...
Then it reboots back to the ACER logo, and just sits there. I have downloaded one of the ROMs and done the VOLUME with POWER BUTTON start up and it doesn't do anything. Just stays at ACER logo.
I've looked at quite a few things here on the forums and it hasn't done me any good -- nothing seems to want to work with the tablet unless it's in debug mode (which means it has to be a working tab). When connected to a PC it does detect as an MTP USB DEVICE and says "THIS DEVICE IS WORKING PROPERLY." But I can't get much of anything. The only thing I've used that remotely works is USBDEVIEW which gives me the device info including a serial #, which I understand is NOT the cpuid. I do have the box, so I guess that would have the CPUID? Any help appreciate. More than willing to just blast this thing with a one touch factory reset from the PC, if it will just connect.
If you had it at the dead android guy, it means you probably didn't have the decrypted "update.zip" on your Ext SD card. If you had stock ICS running before, you can try downloading those 4 update.zips I posted a few threads ago. Will have to try each one, and hopefully one of them works.
Here's the post...

It went to the Dead Android guy when it rebooted after a crash. I haven't seen it since. Just got to the Acer logo screen and stops.
Your linked post is going to what it actually shows instead of the real link.

I'm also stuck at the ACER logo. I d/l'd all four of the zips from your link. All four appear to install correctly but when the flash finishes and the tablet reboots, it's still stuck at the logo.
Also, when I just tried the link again, it is no longer working.
where were you coming from when you tried this ? what BL? gb?JB? what recovery , theres a alot of reading to be done with this device Acer didnt make it easy , but if you read and take it slow there are/were some great devs that left the door open for us all to use these ? Explain where your started from and how you got to where you are now? (Moscow is a sharp dude he can help)!

I bought the tablet used and it would loop on the green "ANDROID" screen. So I don't know what version it was on. I tried the volume +, rotation left and power on to clear the cache and user data. After that it hangs at the ACER screen. I'm assuming it had HC because it has standard recovery. IOW, if I hold the volume - when powering on, it goes to the green Android logo and if an "update.zip" file is present, it will flash it. I've tried just about every "full" ROM I can find and most of them flash but none of them get past "ACER".
I've tried pushing the reset button while powering on while connected to both a Linux box running Mint 15 and a Win7 box. The Win7 box see the tab but won't load the driver. Even though I d/l'd the USB driver from the Acer site. Mint 15 sees the tab but comes up with the error box saying it can't be mounted.
Hi, I have acquired an Acer Iconia A500 that was previously rooted(Or so I was told) and ran fine for months until recently. Now it only boots to the Acer Screen. Ill list what I have done so far to try to remedy this problem.
Reset
1. I hold Volume Up, Turn on the power, and switch the Rotational lock on and off until "Erasing Userdata and UserCache (I think, I see those two lines but don't really remember exactly what they were)
2. The device resets and gets stuck at the Acer boot menu.
Load an Update.zip from my sdcard.
1. This method just gets me to the Android guy with his chest open and a red exclamation point above his chest.
I apologize if threads like this already exist I have been searching for hours on how to fix this problem. If anyone is able to help that would be great!
Hi, my wife got an Asus Zenpad 10 (Z300 series) tablet not too long ago, and recently it seemed to be acting up. It didn't seem to know what its battery level was so it'd suddenly shut down and would rarely stay on for a few hours if that.
I've been reading these forums and Google searching every evening for days now to no avail.
The the other day when i turned it on, it was in a bootloop. I had this happen on my own tablet so I was aware of using ADB and the recovery menu to wipe the davlik cache.
Except, that this Asus tablet only has fastboot screen (which I'd not seen before - my Samsung went to a different recovery mode), so I've been researching that more recently.
I got ADB and Fastboot working, erased the cache via Fastboot which stopped the bootloop, but it would only go as far as the logo with the little spinner circle. After messing around with fastboot trying to do a factory reset and put a custom recovery on it (TWRP) it now will only boot to the Asus logo and not even have a spinner anymore!
The flashing of anything - recovery, stock rom from ASUS (this file as I found elsewhere on these forums: UL-P01M-WW-3.3.8.0-user.zip -- although I'm not entirely sure i'm flashing correctly).
Anyway, I'm stuck with only an Asus logo or fastboot mode screen and am not that good with fastboot/adb since I only had to delve into it once to fix my own tablet over a year ago.
If anyone can help that'd be very much appreciated! :good:
[update]
OK so after failing to flash any zips (or anything!) to the device, I left it on in fastboot mode while I went to work. Now upon coming home the tablet is just a black screen! The laptop recognises it because Windows makes that chime sound when its plugged in via USB. But other than that, I can't get a response out of it Button combinations don't seem to help so now I'm not sure what to do!
Can anyone help me please? :crying:
Unless the bootloader is locked, you may have made a mistake trying to flash the ROM and trying to install a custom recovery. Anyways, if you hadn't made any changes yet to the system, I would have said check the battery first because it may be malfunctioning and not the phone it's self. I know from experience that it may have been the battery considering the way you said it was not reading the battery percentage right and shutting down. And that "bootloop", this was probably happening because it didn't have any power to start up the device as this is exactly what my device did when I had a faulty battery. My best bet is to 1 try to get a new battery, and then 2 see if your system is still intact otherwise try and reflash with the stock ROM (through adb or any computer to android debugger) and then reinstalling the right recovery that goes with the device or that of which is c-o-m-p-a-t-a-b-l-e.
Using CM12.1 on my SGH-T999
I exactly got the same issue, nothing I particularly have done as far I know, my tablet suddenly rebooted and now is stuck on Asus logo with the little circle that keeps turning.
I tried to let it go till my tablet get completely discharged and also tried to charge it completely, nothing change.
And when I wanna access to the recovery, I just get the green android mascot with the message "ERROR!". So I can't even access the recovery to reset my tablet :crying:
Edit: Tried a fastboot erase userdata and an erase cache, still bootlooping
Sorted
The only way I fixed this was by returning it to the shop and having the device replaced! Not the ideal solution, but it worked. :good:

Asus has the firmware (Nougat) for this Z300M but I've no idea how you would get this loaded. Something to learn but as long as the OS is available you should be able to get back stock, latest OS............
