[Q] Acer Iconia A501 - Frozen @ Acer Logo - Acer Iconia A500

Yet another Newb
I have googled / search / read many posts & threads over the past days & weeks.
I had a Acer Iconia A500 freeze @ the Acer logo screen like so many other have had, BUT I managed to fix it last time.
My mate has an Acer Iconia A501 ( so its got a sim card as well ) & its done the same thing.
I have tried the same process as the last 1, but to no avail as yet.
I'm needing some help please guys as I bet its something really simple , but I cant see why its not working for me.
OK AFAIK its all been stock Acer roms & OTA updates.
Processes so far..
Power on & hold down volume + & slide screen lock get this & then reboots
erasing user data .. erasing cache...
Power on & hold down volume - & slide screen lock get this
Bootloader v0.03.12-ICS: starting fastboot USB download protocol
Power on & hold Volume - release power button when it vibrates / starts to boot , still hold down vol button
I have tried the same update.zip file as my last A500 experience , but it got me to the android icon with the spinning globe for hours, left from any where from 40 mins to over night & same basically a lockup. then tried again & somehow got it to almost 90 ish % & stayed like that for ages.
Now I can only get it to see the green android guy for 10-12 seconds before he falls over & dies with the red triangle & black exclamation mark inside it.
I'm not fussed on what rom etc or even stock acer again as I can OTA it back up to last again.
I would just like it to work again & see where I am going wrong...

Anyone able to assist in my error please.
OH micro SD card is formatted to Fat under Win7,
OR should it be Fat32 ?? ( I am going to format with another A500 Tablet & hope it works better )
Also when I go to start it
Power on & hold Volume -, release power button when it vibrates / starts to boot , still hold down vol button
it shows on screen that its erasing data before booting & seeking the update.zip file from sd card etc..
SO it looks like its all doing what it should be , but then doesn't.

Still looking for the reason why this flash recovery wont work.
Using various versions & ensuring all are renamed to update (update.zip file) & messages on booting are the same.
looking for / accessing update.zip file etc etc
Android guy sits there & now I cant even get the status bar below him , its just the guy 10 seconds & dead with his guts hanging out
Any thoughts or a correct file to go with the bootloader appreciated.
Am I doing something wrong OR is it that corrupt its stuffed ???
Thanks to you guru's for assistance

Next instalment
My next instalment on the "unhappy" A501
I have moved my trying to an XP Pro SP3 machine.
I have installed the USB driver package & also the Windows update for the MTP.
I plug in & turn on , windows detects the Acer Iconia A500 & loads into Dev Manager as Acer MTP
It doesn't load enough to appear as a separate drive in the "My Computer" though.
I spose its a small step , but still getting no where.
Please Help :crying:
as I would like to hand this back as I need to move house & it will take some time for me to get setup again to be able to look at fixing it.
Ask for more info & I will reply ASAP

Uninstalled the MTP update , same for the USB driver package & rebooted.
made sure the Acer dir had gone as well.
Installed USB driver pack again & looked at that it contains.. MTP folder & drivers are in there already ..
Still shows up as Acer MTP & nothing in My Computer.
I did see that it shows up with the yellow exclamation mark after a while & then re connects again. ??
IF I start Blackthunders A500 Filemanager using the power button / vol + & flicking the screen lock on/off, I start with Bootloader ver & "starting fastboot USB download protocol.
IS this any help to fix the tablet ??
edit : How do I confirm it has USB Debugging turned on IF I cant turn it on ???

Hi Noel, sorry you got troubs
Your ext sd card should really be formatted via android, although there is a tool for windows you can use called sd_formatter, HP also have a formatting tool, google either one - I have previously posted the sd_format tool "here somewhere" will provide the link if I can track it down.
The drivers are the most important part of getting your tab up and running again.
If you have the Acer ones and the USB ones installed correctly, you should be good to go. In saying that, it can be a real biarch when you're in the position you're in.
Uninstall the acer drivers, reboot. Do not have your tab connected, wait for windows to fully start and its done updating itself or woteva it needs to do lol.
Run the driver exe. If your tab is not booting its hard to tell if usb debug is enabled or not. ANd windows will have trouble detecting it....sooooo......
Go to the root guide in my sig, post #2 download the "babsector file". You will also need to download an ics or jb rom, there is a stock rooted ics or you can use one of 'civato's' Flex roms - I'm still running one of his old ICS ones and it does me fine, I've not kept up with the latest roms, so I cannot help you much with that sorry!
Download your rom and put it on your sd card (if theres a formatting issue we will find out very soon!!!)
Babsector is run via your PC, now, win7 32bit systems work best for this, so if you aint got one, find a mate thats got one! You will save yourself alot of grief by not using win8. Even XP or vista will work!!
You'll need to enter your cpuid so keep that at the ready.
Babsector will flash cwm recovery and install the unlocked bootloader for you.
After running the first bat file, enter recovery and do a complete wipe, (enable data/media option) It has to be a FULL wipe theres no getting around it. And yes, do the wipe procedure at least TWICE!!!!
Once the wipes are done, flash the rom and then run the b.bat file for good measure. As long as you see the big white "PASS" after running each bat file, you're good to go.
IF there is a problem, babsector will output an error....post that and we'll go from there!
Good Luck

Morning dibb
I have the Acer USB driver pack that has MTP files as well, is this all I need or maybe that's the start of my problems ??
( Acer ones and the USB ones installed correctly ?? )
1 of my many issues is that as its not my tablet , I don't have the cupid at all.
It wont start so I cant get it that way , & tried to connect with blackthunders A500 file manager as well but doesn't output any data that I can see / find.
Im thinking I have to flash with an unlocked bootloader before I can do anything - Yeah ??
I am quite happy to eventually go back to stock ICS @ the ends so anything is good.

R u familiar with Linux at all, its the only way of retrieving yr cpuid.
If not, it will be a matter of finding an update.zip that will work 4 u. There is one in the root guide u can try?

Hi
Not played with any Linux before so this might be funny at best to say the least.
the update.zip you suggest , is that the HC 3.1 full ??? (then rename to update.zip) on sd card & try ??

Yep, there's a guide stickied in general for using Linux to get it.
And yep the hc 3.1 FULL. If u get it booting you can OTA all the way to ics, but that's quite time consuming. So root it and install cwm, that will get u yr cpuid. After that unlock the boot loader!!!
I see there's a kit Kat Omnirom, based on civatos flex Rom, gonna give it a spin myself

Tried using USBdeview to get the cupid, found a sting with 15 character's so tried that with a "0" at the start.
used the SB calculator & then blackthunders APX flasher , but it didn't work.
got all the way through with out any issues , but didn't actually flash it
Had assistance from JdgM3NT4L but still trying
the issue is the CPUID though to ensure I have it
more help the better

Hi dibb_nz
with lots of help from JdgM3NT4L I now have the cupid & can get through all of Blackthumders apx flasher up to the 2nd stage of the flashing where its uploading the image file.
it goes into this about 50 % then just hangs...
How long should it normally run for the flashing ??
.

Oh dear, this is not an error u want to see...Would explain the freezing issues. I've never seen a suuccesful solution for the ebt error. Just keep trying sooner or later it will flash....also the tdv4 file has been known to work , you'll be back on hc 3.2 with that but you'll have root and cwm if that's any consolation, lol...
The manual nvflash methods work best babsector or civs nvflash. If it is a faulty chip then even if u do get it booting it won't be a permanent fix.....
See how u go with the other methods k?

Ok
looks like its almost a lost cause..
using civs flasher in APX mode under win7
gets through the start of the flashing to failed executing command 25 NvError 0x120002
command failure: sync failed <bad data>
bootloader staus : Bct Write Failed <code22> message : nverror:0x42008 <0x6042008> flags :0
then it has *press anykey when your A500/501 is in botloader mode
press any key to continue .. so I did anyway
flashing bootloader : bootloader_v8.bin
nvflash started
[resume mode]
formatting partition 4 please wait.. command execution failed cmd 13, error0x120002
failed!
command failure: format partition failed <bad command>
bootloader status: unknown operation <code: 1> message: flags:0
.

When u tried the apxflash tool earlier, there's an option to "dump" yr bct - If u didn't do that try dumping it, and then choose " use saved bct' , sorry dude its been a loooong time since I've had to do it so I may not have the wording exactly right

Ok thanks.
Will try that as well when I try #17 again shortly.
will make sure tablet is connected in APX before I click "dump"
I assume because I get all this way with multiple programs , the CPUID & SBK have to be correct ??

[Solved] Mystery bricked tablet. Black "android systems" screen

I bought an Acer a500 tablet a few days ago not knowing how broken it is.
After loads of research and attempting different techniques I still haven't had any progress.
The software issue:
When booting up the tablet, it goes to the black screen with "android system" at the top and power off/ shutting down in the middle of the screen.
Fixes I've tried:
1.
Since I don't know anything about what operating system is on this tablet, I have been blindly flashing different "stock" (from Vache) versions of HC.
--The android logo with gears shows up, the green bar loads but freezes when it gets 1 cm away from finishing.
--After turning off the tablet and booting it up again, "updating bootloader shows up on the upper left hand corner of the screen. Then a message pops up saying "apk installer: all pre processes complete". Then it returns to the black screen.
2.
The tablet will not go into apx mode (using the reset botton at the bottom).---Fixed. I didn't execute the steps properly. Apx mode works fine.
3.
I plugged the tablet into an older windows laptop and the computer could not install the correct drivers to sync with the tablet. Again also my lack of knowledge. I installed drivers from Acer.com
4.
These two guides seem to be exactly what my problem is but I can't seem to make sense of them:
http://forum.xda-developers.com/showthread.php?p=24531880#post24531880
http://forum.xda-developers.com/showthread.php?t=1572622
This is as far as I've gotten.
Other complications:
--The battery is dead. I have to use it while plugged in by the charger.
--Most of the thread that I have looked at use Megaupload as the source of downloading their files.
--The original owner of the tablet will not help me out. As I stated before, I don't know what version android OS was on here before it was bricked and on top of that the original owner won't answer my questions. As far as I know though, this tablet is not rooted or has anything "non-OEM" installed in it. The story goes that this tablet was bricked when the owner tried to "update" it. Before that, it was functioning perfectly.
-----It looks like Darvis is having the same issue and frustrations I'm having but reading his threads makes me think that this tablet is a dead end.

First off......I hope u didn't pay much for the tablet.
Secondly the guide above looks pretty straight forward but maybe this is one of the ones that has files at megaupload?
I know that the ra recovery and timmydean's files are accessible as I have downloaded both of them.
Maybe someone who has done this previously will chime in and get you the other file if it is indeed unreachable.

I would suggest trying to connect the tab to a Windows 7 PC after installing the USB drivers from ACER. Then check if your device appears in the device manager. As long as you have its UID you can flash the tab from the PC with one of the EUU tools - check my signature on "how to revert to 3.0.1" or TimmyDean's thread which offers an EUU with rooted HC 3.2.1 (it's linked in my thread as well).
How exactly did you try to get into APX mode?
p.s. I have the EUU files if you can't access them from the threads links. I can send them to you.
getting into apx mode
When I perform the steps (hold reset + power for 3 secs then release power); the tablet turns on as it usually does. It goes to the Acer screen, then android and back to the black home screen. My computer responds by saying that it is "installing drivers" but it "fails to install drivers". At the same time I have the DND.exe open and it does not recognize my tablet.
I'm trying to follow the instructions from the root 3.2.1 v4 file.
I can't perform the first step where it instructs me to turn on Usb debugging. The problem is that I can't open the settings by clicking the clock. Nothing happens.
I realize that one complication of my tab is that it will not charge. The battery power is below 15% so none of these fixes might not be effective for me. That might be the ultimate problem?
CyaN1de-
I paid $100 for the tablet. As of this moment I feel like I paid too much.
Thank you both for you quick replies. I have to say that most of the problems that I'm having is because of my lack of experience but I'm learning. I hope I fix this tab soon.
if this dont fix it, i'll give you what you paid for it;0
someone posted a while back that a hard reset fixed the android systems screen error
not sure where you're at now but no harm in trying it
Try using hard reset:
1) Turn off your tablet,
2) Rotation lock s to your left;
3) Press Vol+ (which is next to rotation lock) and power on simultaneously
4) As soon as the tablet vibrates you can release the power on button and you
should start to switch rotation lock left and right till you see
Erasing Userdata...
Erasing Cache...
Vol+ is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.
Thanks for the suggestion but I didn't accomplish anything by hard resetting it. I've done this many times and nothing has changed.
I haven't given up on unbricking this tablet yet and even though it's frustrating I'm learning from the process. If I decide to sell it, I'll contact you Dibb.

i've seen the 2 methods u described but i've not seen anyone else have success with it apart from the OP'ers - seems OTT to me but hey if it works for ya...
I've used timmydeans method ALOT on HC it never failed to work and that includes reverting back to HC from ICS - if it doesnt work for your issue then id be tempted to use blackthund3rs APXFlash Tool and civato's HC_ICS_Bootloader zip to flash a new bootloader and rom package on yr tab - but for the moment we'll run with td'sv4 - if drivers fail to install then believe me, its a good sign
try this:
I know you-ve probly done it but u need to do it again:
reboot everything, then reinstall acer drivers (yeh i know)
fire up ya tab but dont connect to yr pc just yet -as you said you
doubt usb debugging in enabled so we'll try another way around it
run the prgb20.exe it will scan for the new image but not find it becos youre disconnected...thats good....
after maybe 5 -7 minutes of scanning for the new image - it will show a
window "cannot detect yr iconia tab"
and instructions for getting into apx mode - go ahead connect usb put the tab into apx BUT don't click next until....
the drivers will try to install, dont let windows search but let me choose
(off memory) choose device and adb or android ph should show up here
the acer boot/recovery drivers should install...maybe even under USB Controllers
once they do and only when they do click next to put tab into:
acer download mode.......
as i said this is worth a go,,,,how about the update.zip have u tried that.....
else the only other way i know is apx flash....ya still need to get into apx
mode and if u cant then ???? sometimes youll try something over and over
and then out of the blue it will work...you'll swear you never did anything different , it jsut worked this time.....
hope you find some joy
Thanks Dibb for your words of wisdom. I've put it aside for now but I'm going to pick it up in the morning.
As addition to what dibb_nz said - Windows 7 would do the trick - I'm almost 100% sure you'll be able to connect in APX mode with the drivers properly installed. Then use one of the EUUs.
Drained battery really looks like the ultimate problem now because as far as I know you cannot charge the tab in APX mode - haven't tried that. Eventually I would suggest to crack the tab open, remove the battery and charge it somewhere - I don't know alternative ways but...may be another tab or you own charger with proper connector ...
http://www.youtube.com/watch?v=xvXihNIdQ1M
p.s. 15% power ... seems enough to flash through the PC...but who knows - don't waste them and get everything you need before starting the procedure.
no probs m8 hope u have better luck tomorrow
if u wanted to try the EC method i have those files if you want them
good luck m8

So I went through all these steps and the TD's V4 tool finishes updating the tab. But then it continues to the same black, android systems screen. And afterwards the tablet won't connect with the computer.
I am currently downloading the update.zip so i'm going to see if that will work.

do u get on yr tab the big 'PASS' in white leetters or "entering download mode" at all???
think we're beyond update.zip if EUU failed but you can try it -
you can get to apx which is a start - getting a new boot/recovery image on there is the main priority I think...as i posted earlier i've only ever seen a fix for this problem work for 2 people, so on new ground here....
But anyway check out the APXFlash method/walkthru in my sig....all the info is in there and the links to the required files ....do we know if you're on HC or ICS B/L????
I got the word pass; now using recovery mode to flash a rom.
not sure which bootloader I have.
I am using:
Acer_A500_7.006.01_COM_GEN2: http://vacheandroid.com/files/Acer_...1_COM_GEN2.zip
But after it says install from sdcard complete it also give me the message:
E: Can't mount/ dev/block/mm....
E: Can't mount Cache: recovery/log
E: can't mount open cache: recovery/log
E: Can't mount /dev/block/mm...

dibb_nz said:
yes if you're talking about the stock roms from vaches thread, you need the full rom package - you cant just use an 'update' package as they need a full rom to work properly....
for instance my original HC3.2.1 Stock build is 7.014.15_COM_GEN1
and theres no FULL Rom for 3.2.1, so i have to use the HC 3.2 FULL instead
.....Acer_A500_7.006.03_COM_GEN1.zip
Once flashed, thankfully I recieve the 2 small OTA Updates to get up to 3.2.1 again
Another couple of days the ICS OTA d/l'ed and installed with no probs....
is that clearer or am i making things worse????

What I've learned from this whole process is that all of the obstacles I'm facing are due to my lack of knowledge. Thanks for sticking with me Dibb. I can't thank you enough.

I could never get mine into apx mode with the usb cable plugged in. So try that if you haven't. And it is literally hold reset, then press power, without letting up on the reset, release the power button after 3 seconds (use a watch or timer!) then one more second before you release the reset... It does work, but the timing has to be close. It must have a tenth of seconds or less tolerance. Very picky... I've done it on 2 different a500s so far and I am heading to do another tonight. If it doesn't work I'll be right back!!!

Crikey just as I finished typing "....land"
Back to more important matters..... whr u at m8????
None of the roms I've tried to flash go to completion. I'm stuck at trying to flash different roms from recovery mode. Not much luck with what I've tried but I'm going to try more before I give up.
Are there any particular roms I should try more than once?
Or why am I getting the "error" messages stated earlier?

Or why am I getting the "error" messages stated earlier?

recovery mode???
u need a new boot and recovery image on that thing
the HC EUU based flash arent working even tho u got a PASS on screen after TDv4
So HC based methods arent up to it. You need nvflash/fastboot.
We need ICS with the unlocked bootloader it has access to another level below where HC worked because HC b/l is and always has been locked down.
If ICS cant fix it, I have no idea what will and my offer to buy is off the table!!!!
check out civatos guide and ready yourself for nvflash via zip files in that post or blackthund3rs APXflash tool, with a complete tutorial for using it, all links in my sig.
good luck
Just to chime in with a tip on getting google drivers to work.
When getting any device not recognized, or driver error, generally I go into windows device manager, select the unknown or offending device, update driver, only I choose which driver to use, and ignore the error message where it says "may not be compatible with your device", and use it anyhow.
I get that occassionally when swapping back and forth between devices.
Also, battery not charging and display errors, are usually a sign of EC Power control. So you were on the right track about that. Once you get a rom up and running, if the batt don't charge, then there are some EC flash's you can do from CWM.
Back at it again using BT's nvflash tool. And tablet is still bricked.
I've tried a few different bundles and none allow me to operate the tablet. Everything goes smoothly and I get "pass" at the end of the process. When I go to reboot the tablet, it gets stuck at the black start up screen.
Found another lead: http://forum.xda-developers.com/showthread.php?t=1579490
Sounds like he was in the same situation as I am but has a bit more skills and knowledge dealing with problem solving.
You say you were able to flash roms. So apparently recovery is working OK. Have you tried flashing civato's flexreaper? It has code that will detect whether you bootloader is HC or ICS. You may just be flashing a rom that doesn't match your bootloader... I know I'm jumping into the middle of this, but it's just a thought.
Also, when you did the hardware reset with the rotation lock switch did you get the confirmation that it was, in fact, being wiped?
Failing all that, I'd be willing to take it off your hands for spare parts...

How to unbrick your tablet!!!!!!!!!!!!!

**NEW GET THE TWO ICS ROMS http://forum.xda-developers.com/showthread.php?t=1633907**NEW
first download all three of the files
open the acer decrypter and run it
now where select the input file, should be in downloads folder(leave the output folder
remove the sd card from your acer a500 and put it into some kind of device that can hold an sd card and plug it in
select usb mass storage device or disk drive on your device
go into your download and open the DECRYPTED rom
Extract the whole folder to desktop
now copy all of that to the sd card through your phone/device
shut off iconia tab
hold power button and VOL- until it says entering recovery mode
now you should see a green android guy with gears in him
DO NOT TOUCH ANYTHING
hope this worked, it worked for me!!!!!!!!
*************if the first rom doesnt work do the same steps for the second one, be sure to delete the first one off your sd card*********
any input from other users,... success?.....failure?.
just think this is good info..."if correct" i wouldn't mind having this knowledge if it works
Yes, it works. I did it a few times to unbrick my A501 this week.
I had broken my recovery also, so the EUU version helped in that case, but at least I got a clean start to go to another ROM.
hope this has worked if it has please hit the thanks button
When you say SD Card, do you mean the external SD card, or the onboard card? I need to do this, but my tablet isn't recognizing my external SD card. Is there another place for me to put the files, where the tablet will access them?
You need to us ethe external one, in cwm mount SD card
lol im such a dope ive actually used the EEU rom to ix the verified boot failed error when i first loaded flexreaper.....lol mind becoming more cluttered then my pc.
For a cluttered PC I would recommend advanced system care hahahahhahahahha and for your head a good run or bike ride or even a nap

Hi,
just a question, why download the 2 ICS ?
one of the 2 is enough ? Which one to choose ? What is the difference ?
Thanks
Only boots to recovery
So i have been using the flexreaper rom and i tried installing the newest revision and when it all finished (i took all the proper wipe steps before installing) and now my tablet only goes to the acer screen... I have tried other roms, but no dice. I am going to see if this works.
Great Job!
You did a great job with this post, It works flawlessly
Thanks!
My Iconia does not even boot, all I have is a black screen with the power light on. Will this method work for me?
Try pressing the power button and volume up at the same time and if you see the green android with gears, you are good to go.

[Q] A500 - "Android logo" loop

hello everyone ,
my Iconia A500 , just broke down or i don't know exactly what's wrong with it ,
it's rooted stock -ICS-4.0.3 , 6 months ago
and the last thing happened in the past 3-4 days :
1- "Air Playit" was downloaded 2 days ago
2- reading news /Facebook/messenger , occasional games
3- opera browsing
that's it , no physical impacts , nothing abnormal else
now for no reasons , the tablet shut down ..
and stuck on "Android" logo ...and never past that for an hour , then it shut down
any help please with "preserving data"?
I would connect Micro USB cable to PC and device...
and see if PC recognizes device...then if you can see it in ADB or APX mode..
at least you can modify stuff with PC recognizing it..
Maybe take out External SDCARD and click it back in.
try to boot into recovery mode
mess with it when power cord is plugged into it and NOT plugged in
*** IF you are ever are able to enter into a RECOVERY mode, I'd wipe Cache + Dalvik (so it can refresh files and apps) (it doesn't erase anything, settings, apps, etc)
hope you have your CPUID #
Dought this is very helpful, APX mode saved me after my tablet was bricked for 2 months

Well I wish that I could help in a way that would let you preserve your data. Hate saying it. It is probably lost. The 'save my data' prerequisite is probably why there are no answers to this point. I won't say that it is impossible, just highly unlikely. Sorry.
So if you get tired of waiting for an answer for that and just want to get your tab up and running I would humbly suggest that you consider these...
http://forum.xda-developers.com/showthread.php?t=1624645
Tons of great information and the support from the OP is legendary.
I think that you will end up at this page...
http://forum.xda-developers.com/showthread.php?t=1751978
This one is not an easy read or an easy process for those who lack Linux experience. But with a little patience you should be fine. Just be sure to read through the first few pages. There's a decent amount of information in that single thread, and not all of it is in the first post.
Once you get through those two threads you will, without a doubt, be able to continue with restoring your tablets software to something useable.
Good Luck.

I'm in the same boat. The same thing happened to me two days ago. Stock ICS + root are the only mods I've done.
I'm going to finish reading through to see if anything worked. :/
---------- Post added at 03:53 PM ---------- Previous post was at 03:42 PM ----------
In my case, I'm not so interested in preserving any data as I had already relocated everything important to GDrive and my external SD card.
First attempt, I tried booting into recovery which, I'm guessing, tried to grab an update.zip from the SD card that wasn't there. When nothing was found it proceeded to a green android boot screen and then quickly changed to a dead android with a hazard symbol on it. The boot bar below the logo crept slowly for several minutes and then stopped and hung for about an hour until I gave up.
Any quick ways to get me back to a stock blank rom?
ok , i think i'll let go for the data ... although it's VERY annoying -_- considering i did never lose any data since 1990 with dos / windows / symbian , i'm very disappointed with my first experience with Android and Acer ..
anyway here is my thoughts ,
1- first i tried All possible ways for extracting the CPUID in many forums .... except the "Ubentu" one ...which i'll give it a try soon after my surgery exam
2- another VERY annoying point honestly , it's the "inconsistency" ....
i mean , when i pressed the reset , it stopped showing me the "android-logo" , then after couple of resets , it started to show it AGAIN !!
then , doing hard reset (+vol + pwr + the or.lock) and confirmed erasing data and cache , the "android-logo" disappeared , and only ACER !!!
another , one normal reset , and it appeared again !!
ok ok ... let's forget this
i tried all 7 Stock ROMs ...
each SINGLE ROM , gave me at least 2-3 different responses !!
- the loading bar alone
- the robot with rotating thing , no loading bars
- the dead robot , no loading bar
- the robot with rotating crystal , with loading bar which get stuck at 25%-30%
- the dead robot , with loading bar which get stuck at around 20%
- Nothingness !! ( yes , it boot up from update.zip , then nothing happen)
*each trial , i gave it at least 20 min to progress up ... but with no use
anyway ,
3- i'll try again last time extracting CPUID , so i can install EUU ROMs .... but anyway ...
guys , does anyone know any relation between the S/N of the machine and the CPUID ?
just trying to think alittle bit differently , maybe , the S/N is 22 units long , so maybe there is a relation between them ?
4- if all failed , i think i'll have to wait till i get to dubai soon , because no service center in my country -_- !!
5- last resort , i'll use it as cutting table in my kitchen -_-
please guys ... help
IDEAS !!
i know you said the drivers are installed but I'm not sure they are....but try this
put your tab in manual apx mode and hook up to your pc - if theres an apx device listed then run afterOTA Lite version to get your cpuid that way...there is no relationship between the serial no and the cpuid...if nothing else works the only answer is Linux, as all the others have said
ok here what i have done ...
installed Ubuntu 12.10 ... done
installed all developer packages ...done
extracting the UID ... 0x3806148417f4317 ... done
double check ...the same result ...done
trying to convert to SBK ... FAIL
adding extra -as advised- "0" so the UID become ... 0x03806148417f4317 ...done
converting to SBK ... done
back to windows 7 ...done
trying to make "A 500 manger" or "A500 APX" detect the tablet ...fail
windows detection to APX .. done
retry "A500 manger or APX" ...fail
downgrading from "acer USB drive" 1.06 to 1.00 ....done
trying "A500 manger or APX" ...done
on "A500 APX" ... chose package 13 , put the SBK , APX detected , the tablet show "Acer" in green color with "Acer Iconia APX Mode" ... (finally something different)
"A500 APX" asks me if i saw the new "APX mode" ... yes
and then
it continued in all steps with success
till reaching " Exiting the bootloader..."
and it hangs for 30 min on that stage with no respond not what so ever !!! -_-
any ideas , guys ?? :fingers-crossed:

Hello! What did you do in the end? I have something not exactly the same, but a similar situation to yours. Your final solution could be my salvation too...... :crying:
Thanks in advance for any help.
Regards.
The tool he used flashes a custom recovery as well as the unlocked boot loader..for some reason the recover.img got corrupted...u must use the ones that come with the tool and use the tool to install it. Once u have the unlocked boot loader you're able to use a flash able zip to change it if u want.
So to answer yr question just reflash again. Choosing the bundle market option select bundle 17 its the latest version and seems most stable.
The window in the s/shot is fast boot menu, power volume up. Wiping cache helps if you are stuck on Acer boot logo

[Q] Iconia500 shows white power light but no screen or vibrate

My old charger for the Iconia 500 broke and I got a replacement charger (not acer). When it came the iconia was already completely drained. I plugged it in, charged it, and since then the only thing that happens is this:
- I push power and after about 3s it turns white. Nothing happens on the screen, no vibration, nothing.
- I can turn the power back off by holding the button for 5s.
> I have tried holding the button longer but no difference.
> From what I have read I suspect it might somehow have gotten into APX mode?
> I have tried to read through the numerous posts on this forum but cannot quite find this same problem/am overwhelmed by the lingo.
> I have tried to connect the tablet to my PC with a microSD cable, and it lists it as APX, category unknown, APX doesn't have a driver
- Can anyone confirm/suggest what might be wrong with my tablet?
- Is this something that can be fixed at a repair shop?
- Is this something I could fix? (I have no ID's or codes for the tablet, have never played with APX mode before)
Thank you for any advice!

Hi chris, yes you are stuck in apx mode.
To fix this you must have your tabs CPUID.
The easiest way is from an old nandroid backup, thats if you have one. If you do, look in the cwm backup folder under cpuid.txt
If you dont have a backup, your only chance is thru ubuntu. There is a guide by "srbeen" stickied in the General forum.
If you can retrieve yr cpuid, post back here and we can help u get fixed. YoU will need anutha file to do this tho'. Its called babsector.rar and you can download it in post 2 in the root guide in my sig.
You will also need a rom to flash - only ICS or JB.
To summarise,
1. Retrieve the cpuid/sbk
2. Once you have that then
3. Download babsector and a rom.
4. Come back here for unbricking help.
Good luck with the cpuid/sbk, without it you can do nothing.

Thanks for your reply and your advice! It is nice to have the confirmation about what the problem is, and a step by step guide to start tackling it. I feel a bit less lost now I'm going to try to follow your steps and will let you know if I get stuck anywhere.
- Chris
next steps?
Ok, so somehow (a miracle I guess) I managed to do your steps:
- installed ubuntu
- followed srbeen's steps upto the point where I got my CPUID
- got my SBK
- downloaded babsector.rar (luckily chrome offered to translate the russian site I found it at)
- unrarred it
- downloaded a ROM from http://forum.xda-developers.com/showthread.php?t=1935582 (is this an appropriate ROM?)
- unzipped the ROM and copied it to the external micro SD card
Can you point me in the right directions for the next steps?
Thanks,
Chris

Hi dibb_nz (and others)
I am still stuck. I have been trying several things, but none worked so far.
- I think the drivers are installed properly. When I go to device manager it lists APX under unspecified device - with Acer USB Boot recovery Driver installed under the hardware tab. It also says Model: APX, Category: Unknown
- I tried to run babsector, and it gives me an error. Before giving me the error it does get my tablet to show the text "Entering Acer Download Mode" in the topleft corner. Then I get the error "failed executing command 16 NvError 0x120002, command failure: create failed (bad data)" in the attached image.
- I also tried to follow the steps in Timmy Dean's V4 post, since I hoped maybe that would help, but that also gave me an error. (Red letters saying it failed, and to follow the steps again and try again).
I feel once more defeated, and hope you know what to do next.

OK< there is a slim chance u may be able to recover your tab.
There is a bct error - usually only one tool can repair this.
Download the apxflash tool.
Power your tab off.
Enter apx mode via the buttons - DO NOT use the tool to do this -
Connect your usb cable.
Run the tool - choose to go to the bundle market and download bundle 17.
If the apx driver has loaded and is showing in device manager then continue with the apx flash tool -
You will eventually see a window asking whether to dump and save yr bct, choose yes.
Hopefully the tool will carry on with the flash, once thats done, boot straight to recovery, complete the wipes and formats and then flash your rom.
I have done the steps below.
Just to make sure, when you are talking about the APX drivers being loaded, do you mean the one I see when I go to devices, right click on APX, choose hardware, where it says "ACER USB Boot-recovery driver" under device functions?
So when I tried to dump my own it gave me the following error (attached as image):
Unhandled exception, could not find file bct.dec.
It gave me the option to try to continue anyway, which I tried, but now it has been hanging in the screen "staging and backing up BCT, Using default BCT" for a long time...
so, does this mean it really is dead? And if so, what part of the tablet is dead? And if not (*hope*), then what else can I try?
Thanks,
Chris
ps. my tablet was never rooted, so I don't know if that complicates the matter... it does say that it needs to have been rooted to choose the dump option. Moreover, I never was able to turn USB debugging on, because I don't have access to the tablet. It does nothing besides black screen and occasionally the "Enter download mode" (but not with these steps)

Just to make sure, when you are talking about the APX drivers being loaded, do you mean the one I see when I go to devices, right click on APX, choose hardware, where it says "ACER USB Boot-recovery driver" under device functions?

yep thats correct
So when I tried to dump my own it gave me the following error (attached as image):
Unhandled exception, could not find file bct.dec.
It gave me the option to try to continue anyway, which I tried, but now it has been hanging in the screen "staging and backing up BCT, Using default BCT" for a long time...

Do you have the latest version of the apxflash tool....as far as I know, this is the ONLY way to fix a bct error....
So if you try and save yr tabs bct but you get the error and if u try to continue it just hangs???
The only thing I can suggest now is to power off both devices and then power on. When u get to the bct option try the default option first if it still hangs, power everything down again and this time try saving the bct again. Not much help I'm afraid, sometimes the tools do get stuck, and its best to power down and try again.
so, does this mean it really is dead? And if so, what part of the tablet is dead? And if not (*hope*), then what else can I try?

I hope not!! If the tool insists on hanging, you can TRY the babsector file, post an error if you get one. Its in the root guide in my sig, along with instructions for use
good luck

EDIT: Added attachment apxFlash Tool v1.1.1 @CKM80
Well, I am trying to again with the default option, but it has been saying "Flashing bootloader (EBT) stage two - uploading image" for 45 minutes now, while another nvflash.exe window that popped up says "nvflash started, [resume mode]"
The tablet says "Acer Iconia APX mode" in the topleft.
I am not sure if it is doing something still (after 45 min) or that it is hanging.
I will let it sit a while longer, and if it doesn't work I will try all options again.
Will keep you posted.

All I can tell u is that 'sometimes' after trying wot seems everything a hundred tries or more, something finally happens and it works...this doesn't mean you do not have a faulty memory chip, as this is just what happens...you could try it next week and it may well work....no consolation I know...
You might wanna try a friends computer (specially if they do not have win8!!) you neva know yr luck!!
Yeah, I think I'll try a couple of times, but I am pretty much ready to give up.
Thanks for all your tips along the way.

Cant Flash Custom Bootloader/Recovery on A500 (ICS OTA 4.0.3)

So ive been trying for almost a week now trying to put a custom ROM on my Acer Iconia A500, but my tablet doesnt want to do cooperate. I have tried EVERYTHING, from using blackthunders APXFlash tool to NvFlash and everything. My problem is my computer will pick up my tablet once its in APX mode. I go to my "Devices and Printers" and under everyting it has a picture of a object and under it, it says "APX". Also in the bottom right corner of laptop theres the "Usb" icon and if i click on it, it says "Eject APX", so i know my computer knows what it is. but no matter WHAT program i use, my A500 never gets any white text on it when its trying to go into the bootloader or anything. i can only get to the point where my device is in APX mode.Nothing seems to work AT ALL. And all the programs get to the point of trying to flash the bootloader and thats it. They just stop working or cant go any further for some reason. I also deleted my "boot.p" file in /system as well. I got my CPUID, i got my SBK, i got all of that using Afterota program. My tablet IS ROOTED. So im stuck right now. Tablet runs fine and good. Just dont wanna give up and really needing some help. Heres my tablet info:
Tablet Cpuid : 037C61C9408103D7
Tablet Sbk : 0xE4531F00 0x18070000 0xF74EE402 0x11DE2003
Android Build : Acer_AV041_A500_1.033.00_PA_CUS1
Bootloader : 0.03.12-ICS
I also tried downloading the "babsector.rar" file from the russian website and it says the file was removed, id SO GREATLY appericate it if someone who has it could re-upload it somewhere else or gimme a good working downloading link for it. One again please help me out if you have ANY suggestions or know how to fix my issue. THANKS

First of all thanks for an informative post!! I wish everyone gave as much info as you One thing you didn't mention was which PC OS you are using - 32bit are best

Right, everything is in order here, you're seeing exactly what you are supposed to
So now we need to know "what" doesn't "work".
The babsector file is best for trouble shooting as it will always post some sort of output. Its in post2 of the root guide in my sig.
1. Put your tab in apx mode and connect your "micro usb cable" to your pc
2. Run the first .bat file of babsector.
Now what exactly happens next, can you post a screenshot?
Can't help much further until you do this!!
If the first .bat file runs ok, you need to boot directly to cwm which babsector has just flashed.
Do a nandroid backup and then
a complete wipe including /data/media - you need to go in and specifically enable this from the 'mounts' menu. Wipe davlik and cache too.
Now flash your custom rom and power down.
Back into apx mode and run the 2nd .bat file.
Reboot and voila! you should be all good - fingers crossed!!!

OK so when I put it in APX mode and connected to it, I ran the "A501 A" file and entered my SBK. But when I hit enter it will work just fine alllll the way up til it says something about sending file to bootloader, and then just fails. This is the SAME thing that happened when I use NvFlash and APXFlash! None of them can seem to access my boot loader and I never get anyway white text on my Acer saying it is! So idk what to do! I can't post any screenshots at the moment since I'm not home right now. I will once I get home. Also I can't even enter stock recovery on my tablet! I turn it off, and as its turning back on I hold the "Power" and "Volume Down" button, but just boots normally.....so Idk if this has to do with the problem or not....

Well that sux because I thought we were on the same page, except you got it working. I get stuck on uploading the bootloader stage 2 in apx program.
Also when I try to load recovery.
It does a laying down android with a triangle and a exclamation point in it.
I found the cpuid from navigating to the android file folders.
0428004342e0e297 which converts to this
0xC7E2C201 0xDBFDC006 0xDB922404 0x44312103
Is there a way to verify that I do in fact have the correct one?
I really want to update my rom, but I don't know what I'm doing wrong.

What I did was went to the Acer website and found my tablet and installed the HoneyComb driver that was right under my ICS firmware. (Since they didn't have any drivers for the latest ICS OTA 4.0.3) which these drivers will work fine. Next after I reinstalled those drivers I put my tablet in APX mode, connected it to my laptop. Made sure in the bottom right hand corner it had installed the APX drivers successfully and made sure under the usb icon it.said "APX". I then flashed the a501a file first and it went through and worked! Them from there I went to wipe what I needed and installed my custom rom!
