Not booting

I can get into APX mode. I can boot recovery (power + volume-down). I can boot to menu (power + volume-up). I can Wipe (factory), wipe cache, wipe davlick-cache. I can format /system, /data, /cache, and /flexrom. I can install custom ROM (or at least that is the assumption).

I have also installed this boot-loader (a500_a501_bootloaders_apx_ics_v9.zip) using the BlackThunder's A500APXFlash tool. Which also installed the CWM recovery.

I am trying to install this custom ROM (CM10-FLEX_V6Supercharged_Rev3.4.zip), although I have also tried (cm-10.1-20130606-UNOFFICIAL-a500.zip).

After wiping/formatting and installing a custom ROM, I always get stuck on the Skrilax Boot Screen.

I get the Linux-Suse-Like logo with the Skrilax_CZ's bootloader V9 text. I get the Booting android image from LNX partition. . .message, but it will never boot. When I tried this custom ROM, cm-10.1-20130606-UNOFFICIAL-a500.zip, the only thing that is different is that when you think that the screen is going to switch modes and bring up the custom ROM boot logo, the screen flickers for a second, it looks like a horizontal sync issue occurs, and the Skrilax boot screen gets borked and nothing happens.

The tablet charges, the screen appears to work (at least everything works as expected in the Aroma installer of CM10-FLEX).

I have tried all sorts of combinations of custom ROMS and wiping/formatting of file systems. None has successfully given the ability to get past the boot screen.

Any suggestions here?

Thank You.

I've had exactly the same problem with my A500. I've managed to get it to work.

What I've done is - I've downloaded older version of bootloader (v8) - a500_a501_cwm_update_v8_blue.zip, extracted bootloader.blob from it into the directory with flashboot.exe, then I've connected tablet into USB, switched it into fastboot mode in bootloader (power+vol up) and I've typed in command line: fastboot.exe flash bootloader bootlader.blob

After tablet has restarted itself, I've went into bootloader again, wiped cache IN BOOTLOADER menu (AND NOT the recovery mode), then reflashed the newer version of bootlader (v9), following the same steps that I've described above, this time - using a500_a501_cwm_update_v9.zip

From now on - it works again. I hope it helps

I hope I am not out of luck but smehow I bricked my A500 completely. When I press the power button nothing happens except that the power button glows white. I dont get anything at all on the screen or it doesnt vibrate and when I connect it to USB on my computer its not showing so I cant do anything with it. Could somebody please help?
[Acer Iconia A500] DaveLTE:
Think thats dead not bricked :confused:
[Acer Iconia A500] steve30x:
Its not dead. I got it to work again but something went wrong and encryption failed so I have been trying to get it work again with the past few hours. I can get it to boot into the acer logo but it wont go any further and it fails to create a partition for android so I am stuck.

It turned out that it wouldn't work while the tablet was charging. I got it to boot past the android logo but I am getting "Encryption Unsuccessful"

same isssue

I have the same problem and i get your point and all the process to NVFLASH or APXflash but when i start the process my USB driver called Acer PIcasso USB bot recovery driver vanishes and its obvious if that vanishes then nothing can be loaded, should i have two usb drivers or what?
[Acer Iconia A500] dibb_nz:
Ok, check device manager or the safely remove Hardware icon in the system tray. You should see an "apx device" listed.

If not, disconnect yr tab and reboot yr pc.

Power off yr tab and using the buttons enter apx mode "manually".

Connect yr tab to yr pc.

Windows should recognize an apx device.

If it does not. Uninstall the drivers. Reboot and reinstall them.

Edit: using the manual method to nvflash will always work after you've been stuck in apx mode.

I'm getting

"Your operating system isn't compatible with the upgrade application. Please download .NET Framework 2.0 or above from Microsoft website.."

I've tried running it under different compatability modes to to luck.

Anyone else have this problem?

I saw this guide and I figured I may as well give it a shot.

Also, I'm currently running .NET 4.0, so I don't see why it should be an issue ;_;
[Acer Iconia A500] dibb_nz:
It may pay to specifically download net 2 if u can find it. I know way back in the day I had to do this. I have a copy stashed some where....

There is a reason why DotNetDetecter.exe is included in the EUU, if it does not detect the files you won't get very far as you have found...

do u have access to another machine?

Will the update.zip method not work for u?

Same issue as Joey

Hi,

I am having same issue as joey. I did all the way as joey did. I am enable to go in APX mode. i don't have UID or CPUID. The code sent by eppeP i didn't get how to run that or how to get UID using that code and how to use libsub win32. I appreciate if someone can help me. I am trying lot to flash my Acer A500 Tablet.:o:o:o

Thanks.
[Acer Iconia A500] eppeP:
Depending on which version you need one of:

Windows:

libusb win32 (will require installation of a separate driver)

Windows Driver Development Kit (can use the winusb apx driver provided by Acer)

Linux:

libusb 0.1

libusb 1.0

Whichever one you choose must be installed before you can build the tool.
[Acer Iconia A500] jd4r:
I Have windows 7

Thanks eppP for responding me back quickly. I am using windows 7 64 bit. where i can find winusb apx driver? actually i try to install libusb win32 i don't know its installed or not. I run inf_wizard.exe file. Please guide me.
[Acer Iconia A500] eppeP:
I'm not a Windows user and don't expect to have access to a windows box until somewhere March/April so I can't really guide you, but if you have any specific questions I will try to answer.

Those are two very different things, the winusb driver and the libusb win32 driver.

The winusb driver comes with windows (at least newer versions), then it is mostly a question of associating devices with it, Acer used to provide 'Acer Picasso USB Boot-recovery driver' from http://support.acer.com/product/default.aspx?modelId=3851 but that does not seem to be the case anymore. It is probably still there on the site somewhere.

This is the driver used by nvflash so you don't need to change drivers, but to compile an application using the winusb driver you need the 6-700MB Windows DDK.

libusb is considerable smaller, but in oder to use nvflash you need to remove it again.

I have some instructions in the README.txt files in the repository (libusb is in the top level, winusb in the winusb directory), those are rather high level and assume that you have an idea what you are doing.

http://git.pappkartong.se/?p=a500/apxuid.git;a=snapshot;h=master;sf=tgz

.
[Acer Iconia A500] jd4r:
Help me.

Thanks eppP for valuable information. One thing i don't understand. As you mention in readme.txt file

- If using MSVC: Update the library and include paths for libusb-win32 in the MSVC project

(LibraryPath and IncludePath in apxuid/apxuid.vcxproj)

- If using GCC: Update the library and incldue paths in the Makefile Running:

How can i identify that which one i am using MSVC or GCC?

Also i didn't get how to Run apxuid from cmd.
[Acer Iconia A500] eppeP:
Those are Microsoft Visual C++ and the GNU Compiler Collection, you will not have either unless you install it, so you will know.

cd to the directory, write the command, press enter.

[Acer Iconia A500] dibb_nz:
Ok, you have yr cpuid/sbk.

You've run the EUU and yr tab has entered "acer download mode"....

Wot happens next?

Yr tab should display "PASS" what does yours do?

Think u should run the babsector.rar file...see post 2 of the root guide in my sig.
[Acer Iconia A500] jd4r:
Still Having same issue

Hi dibb,

When i run EUUS it start and just stay forever after 5% completion. I check in devices in my pc it is showing me APX device. How long i should wait if green bar not keep continue?

I have tried Nvflash too also a500 flash tool. When i run nvflash it just say nvflash started [resume mode] and when i run flash tool it just stuck in Flashing Bootloader (EBT) stage two - uploading image... command prompt popup and showing me that nvflash started [resume mode] i have tried almost all possible ways.

Please advice me what step should i take to start my tablet.
[Acer Iconia A500] dibb_nz:
If the euu hangs there it sounds maybe like a driver issue or perhaps usb debugging isn't enabled??

You're able to get into apx mode and then download mode ok???

Have we been down babsector.rar road yet? You're best to run that and post the output and we'll go from there .... its in the root guide in my sig post 2

[Acer Iconia A500] dibb_nz:
Oops...wrong post

Ok to get u fixed you must run

babsector.rar file. Your partitions are screwed up and this file will not only re-partition yr tab but it will also flash the ics unlocked bootloader and install cwm recovery for you.

Once this is done and you have completed the formats in recovery.

You must flash a custom or ics/jb rom as at this point yr tab has no OS!!!! If you try to boot you'll be stuck on the acer logo.

BAD BRICK

I hope all is not loss, but it looks pretty sad. I flashed my tab using Blackthund3rs flash utility and V8-Thor_1.7.3_recovery.a500x, but I had wrong CPUID. It appears there is no recovery mode and trying to get into apx mode goes in briefly then shows not connected. So I guess my question. Is there any hope?

Update: BTW - this is A500 model - I managed to flash with correct SBK, but it hangs at (Flashing Bootloader (EBT) stage two - uploading image...). Any advice?
[Acer Iconia A500] dibb_nz:
EDIT

SORRY FOR CAPS, SOMEONES JUST POSTED THEY HAD SUCCESS WITH THE EBT ERROR - SEE HERE http://xdaforums.com/showthread.php?p=50064853

THe flash will not take place with an incorrect cpuid, the program will close down.

But with your 'update' I see you have the EBT error, this is a pig of an error, sometimes you can fix it and other times not - run babsector and post the output if it fails. Reinstall the drivers and start with a clean boot of tab and pc...you might want to try tdv4 in the root guide as well, this is a modified EUU, that will repartition and downgrade you to a rooted HC 3.2.1 w/cwm

hi all ok a500 came to me stuck on acer screen all of the 4 stock zips are not working with the android man dieing as he does

also the hc3.1 zip too.

tried to get the acer driver to work on 3 pc`s lol none of which would work agggggghhhhhhhhh

so my question is and please please be gentle which method should i persue rather than waising yet another day flicking from one thing to another with this pesky door stop lool

i have no idea whether its been rooted or anything other than intuition that the owners have probably not tryied this

not much info to go on i no but i cant get it to do a thing apart from when flicking the lock button a fastboot message comes up and then my pc will load acer drivers but abd will not list any devices if im saying that right

diff cables and usb ports all same

appologies for the massive noobness

ed:eek:
[Acer Iconia A500] dibb_nz:
You need to get the drivers installed correctly. You can download them from the root guide in my sig.

What PC OS are you using? Win7 32bit works best. There is no support that I know of for win8. If you have a Linux setup then that works even better...oh and make sure you're using a micro USB cable. If u cannot get adb working there are not a lot of options.

If you do not have the cpuid (see guide in my sig) then my best advice is to forget windows and drivers altogether and use Linux, you'll need it to get the cpuid, you cannot fix your tab without the cpuid.

Read the first couple of posts in the root guide. If you need help with Linux start a new thread.

Good luck

dibb
[Acer Iconia A500] ed1808:
many thanks for your reply im using win7 32bit will persue the driver issue and post back the drivers im useing are from the link in your sig :good:

---------- Post added at 11:16 AM ---------- Previous post was at 10:29 AM ----------

okies i have no also slapped together a windows 7 32bit pc fresh install plus chipset and all updates then once again tried these drivers USB Driver_Acer_1.06.1500_A30H_A500 to no avail tried multiple cables and all available usb slots can i please ask if at this point im supposed to be using the on button lol and not a button combo? many thanks just seems a bit strange that even with 4 diff pc and lappy combos im still not getting anywhere with these drivers thanks in advance

ed
[Acer Iconia A500] dibb_nz:
button combo?? Power tab on and connect to your pc, windows installs the drivers, check the "safely remove hardware icon" and your tab should show there....or go to "Device Manager" and look for "adb interface"

the other things is USB debugging should be enabled on the tab for adb access and I guess we have no idea if it is...

As I posted previous, once you have adb access the next issue is the tabs cpuid, this you must have in order to run the files you need to attempt a repair.

The only way to retrieve your cpuid is with Linux, so you are gonna have to go down that road anyway.

If you tab is one of those with the faulty memory chip then all this work could be for nothing - a new motherboard will be required....

Oh, while I think of it, when you tried the data reset with the lock button, does the screen display a message "wiping data, wiping cache"???

The other check you can make to see if you have the drivers installed correctly and has communication with your tab is:

putting your tab in "apx mode" then connecting to your PC, you should have an "APX Device" listed in "Hardware & Printers.

When it comes down to the nuts and bolts tho - you need Linux to get the cpuid before you can do anything and even that does not guarantee its fixable....
