Hi experts
First of all i had an A500 and was able to do all fine but i ve sold it and now 1/2 year later i want to flash ICS Bootloader for better Roms to my girlfriends A500 because of many problems with sleep of death and thats annoying.
However, i used the blackthunder3r APX Flash Utility V0.4 and downloaded any bundle (i tried 4 differents) but when i switch the tablet in APX mode (doesnt makes a difference if manual or automatic.both put me in apx mode and the flash tool recognise it as APX device) then in the next step i get a pop up "Bootloader Check" and got asked if i have a Logo and "Entering Acer download mode" on my tablet but i have not.
This is my big problem and i m not able to solve it without your help. i m now trying it since about 3 hours now and knew that with the first tablet it took me only few minutes to have what i need.
drivers on pc seems to be all well but i cant start the flash process without getting into that Acer Download Mode.
right now there is HC 3.01 Bootloader on the tablet. i also tried to flash different Recoverys and flash an other Rom before doing the process but all the time i get stuck on the "bootloader check".
On the Tablet the power light is white and the screen is black (as it should be for APX mode) but i think the communication from the flash tool cant bring the tablet in download mode.
I m open for any tips because i dont have any clue what to do because i ve the feelin´ that i did everything.
try civatos manual nvFlash method...theres a guide in my sig
download the v8 package from civs OP
run v8.bat and cwm 1.7.3 option
do you see the system info window come up (on yr pc)
if you do follow steps and put yr tb in apx mode
does yr tab enter download mode now???
do any errors show??
Do not continue with the process if your tab wont enter download mode
otherwise use timmydeans HC 3.2.1 rom, pre-rooted and cwm preinstalled
then try the v8 bootloader from there OR OTA up to ICS
make sure u keep yr cpuid/sbk backed up somewhere
good luck

Thanks for the reply but i solved it yesterday.
The problem was that i had flashed a Bootloader from HC to ICS on my old Tablet.
i dont know how or why but on my PC it showed me in blackthund3rs flash tool automatic the SBK Number of my tab ..... but it was the sbk of the old tab.
i figured it out by connecting my tab with afterota and recognised 2 different SBKs.
finally using the blackthund3rs flash tool, entering the correct SBK and then the tablet rebooted from APX Mode into Download Mode with Acer Logo.
For what every reason the flashtool found automatic a SBK of my old tablet and thought it is the SBK of the new one.
Now i m running ICS and all is fine... dont know why i didnt doule checked the SBK. i trusted the tool to much.
Thread can be close

I have had my a500 since mid-2011 and within having it for 30 Minutes, I rooted it using ginger-break. Then I Used Acer Recovery Installer from the Market to Install Thor's CWM Recovery and Lightspeed rom. I updated to the Lightspeed ICS 4.4 I believe and now Im looking to upgrade to Flexreaper but I need ICS bootloader to do so. I have tried this Method with the tools such as APX tool and afterota, But since I never updated with a stock OTA update from acer the afterota does not work and I have gotten my cpuid and the SBK and both work. I have entered APX mode both manually and through APX tool. But at this point I continue to get errors like cannot locate APX device. I do know that I have the drivers downloaded from the acer website for the a500 and the APX device shows up as "Acer Piccaso Boot Recovery" but It will not show up with the "Acer Bootloader" on the tablet as the APX tool describes. I am currently downloading a stock rom and trying again just incase it was the ROM causing any issues. The Stock rom will be rooted and the recovery will be unlocked. Any ideas on whats happening? Did i mess up by not OTA updating? Is my device an older "version" and I can not properly enter the stock bootloader?
Hi cpgifford,
Did you get anywhere with your bootloader update? I am in a similar situation - rooted in GB - updated to ICS and APX mode does not seem to work.
Had the same problem.
The solution is:
When you are conected to your pc.
You must set your device in apx mode by hand.
Hold the little reset button with a needle or something and hold the power button for I think max 5sec.
If windows say new device found(sound) release the buttons.
If now displays black and the power button is on(led)
You are in apxmode.
Now you can flash the bootloader.
I did it with the blackthun3r tool
I hope that will help you,
when i had the problem i was scared because my devise won't boot any more.
After it all was fine.

if this /\ doesn't work then make sure you have no software that dictates your drivers like driver manager, also disable you antivirus and any cleaning software like advanced system car
Thanks for the update - I will work up the courage to try and flash the bootloader again. atm I am rocking ICS on the GB bootloader so I am not in too much of a rush however all the roms will eventually require the ICS bootloader for more advanced features.
helpw with unbricking a500
Hello all,
I tried to installed ICS based on this post here http://forum.xda-developers.com/show....php?t=1622425.
here are the steps i did
1. downloaded all the items required that is APX flash tool and Thor 1.7.3 recovery, V8-UNL-ICS-HC-bootloader-MULTI-cwm.zip
2. got my cpuid and sbk
3. connected the iconia to computer with usb cable
4. started the apx flash tool.
5. entered my sbk by copy from text file and pasting in the dialog box of flash tool. and clicked the right arrow
6. selected the 'V8-UNL-ICS-HC-bootloader-MULTI-cwm.zip' file.
7. saw the acer logo and the a500 in apx mode
8. finally the flash tool said done and asked to boot the tablet.
9. after booting the tablet, i found that it only says 'Skrilax-CZ's bootloader V8 Bootin primary kernel image"
I am now completely lost as how I can move forward to install the Thor 1.7.3 revoery and the ICS ROM on here.
I am unable to make this tablet go into APX mode as suggested in the post by civato, both manually as well as using the blackthund3r a500 manager. A500 manager reports 'A500 detected in normal mode. debugging enabled.
I would appreciate any help on resolving this.
Thanks

The bootloader is already on your tab. Turn the tab off, press and hold vol- and press the power button to turn it on and see, if it boots into recovery.

I'm a wee bit confused here.
Step 4 OK
Step 5 OK
Step 6 ??
The apxflash tool usually uses the a500.apex files UNLESS u choose use yr own files option
The zip u flashed is what u need to use Civ's manual nvFlash method
BUT apxFlash IS able to use the .bin and .img from the extracted files inside the zip and
I.m wondering if this has caused yr issue with entering apx mode again, I don't think it should have,
but there's been some weird things happening lately so its hard to say!!!!
But for future reference it may be good practice to use the apxFlash-in-app bundles for the initial flash OR
run the zip file via manual nvFlash just in case there is conflict.....
Once u have the patched BL on yr tab feel free to experiment to yr hearts desire, lol....
Just stick with the program for yr initial flash!!!
U now have fastboot available to u, any particular reason u r needing to use the automated tools?
Check yr drivers and reinstall if need be and reboot both devices....

Downloading Afterota at moment. I did find out the cpuid another way.and a side coverts it to SBK. so have both now.
This is how i found out cpuid
[HOWTO] Installing the unlocked bootloader and fixing broken recovery in leaked ICS - xda-developers
will get afterota and make sure is right and get the sbk to.
edit: ok downloaded and unziped Afterota and double clicked Afterota.exe and get error Uac must be disabled before using Afterota. Disable it manually and reboot your pc. program will exit.
???? any ideas?
Ok found out how to disable Uac and got Afterota to run and had to install the driver. and got the Afterota file saved to desktop with all the details of the tablet in it cpuid and SBK.
Whats the next step to do?
Sorry im a noob at this.
Ok I did everything that was in this video here and it all went fine.

So i am trying to unlock my A500's bootloader by using black thund3r's flashing tool. My first problem is when i try flashing it, it gets stuck on the " entering download bootloader" or something like that. This is also while using my custom BCT. Then i try the same thing this time using the default BCT that comes with the program. This time it gets stuck on stage two " uploading". I have no idea what to do or what im doing wrong, can anyone help?
By the way my tab is on ICS and i was trying bundle 4 for the bootloader.

Normally this error means one of two things:
The drivers are failing to install correctly thereby
not allowing yr tab to enter download mode. Or
They are installed and you've okayed the flash without
before yr tab has entered apx mode...."white text on screen"
I'd try a different bundle first (#17) and
Use the manual method to put yr tab in apx mode
Connect yr cable and check device manager for the
acer-usb-boot-recovery driver (under USB controller)
failing that, rolling back to HC via timmydeans rom, and
trying again...
BTW, what rom and BL do currently u have?
And how did u get yr cpuid?

I'll try this in a couple hours, thanks for replying.
I currently have the regular official 4.03 ics that I rooted with blackthund3rs root tool. As for the bootloader it should be the original ics one. Finally I got my cpuid and sbk with the a500 manager.
thank you so much man i did what you told me to and it worked perfectly, with bundle 4. Now how do i get clockwordmod on it? I'm kind of a noob so sorry if this is a simple question.
Okay so it turns out that it didnt work, im still on the locked boot loader . I've tried diffrent bundles even the one's form civato's post, but it still won't work it always gets stuck on stage two. Plz i need help.

U got 2 choices
Try afterOTA tool or
roll back to HC to reset yr tab - have a read of this http://forum.xda-developers.com/showthread.php?t=1839313
Or use timmydeans v4 and jazzys guide

You need the drivers installed
1. Acer website for the acer drivers
2.zip file attached for google/fastboot drivers
Ive attached a .jpg too, u need to have the apx device listed in hardware/printers as shown
3. with apxFlash try dumping your ".bct" when u see that window
4. you can try the afterOTA tool too...
5. if the auto tools dont work then you will need to rollback to HC using tdv4 EUU
6. have a look thru the OP of the cpuid thread for more background info on all things acer http://forum.xda-developers.com/showthread.php?p=25429111#post25429111
I've never had this much trouble before.
Ok. A little back story first. I'm not a moron, I have a myTouch 3G Sapphire 32a Fender rooted using the gold card method, LG G2x - P999 Rooted running CM10, and a SGH-T999 Stock rooted (That's a Galaxy S3 for those who don't know).
I have a friend that got an Acer Iconia a500 tablet a year ago. He's not a power user, doesn't know anything about rooting. All he did was play games on it. One day it wouldn't turn on, the screen was blank. Occasionally it would freeze at the Acer logo, but it would never boot up.
Now it's stuck in APX mod due to him pushing a bunch of buttons(idk how he got it into APX mode so don't ask), so there is absolutely no way to boot the tablet. He never turned on USB debugging, and I can't get into the tablet to turn it on because it's stuck in apx mode.
I must stress this!
I have been working on this tablet for 3 weeks now, and read countless posts about how to fix the exact problem that I'm having with this tablet, the only drawback is: step 1 is always, "Turn on USB Debugging." That is IMPOSSIBLE for me to do at this point.
Here is list of what I do know:
Hardware - Acer Iconia a500, APX Driver Version - 1.0.1.0 Released 4/1/2010 Shows as APX in Devices. Shows as Acer USB Boot-recovery driver in device manager.
Software
ADB info - Android SDK rev.20
ADB ver 1.0.29
Windows 7 64-bit completely up-to-date
Commands: adb get-state, get-serial ------- returns, unknown
Commands: adb remount, root, usb ------- returns, "error: device not found"
Command: adb devices -------- returns no value at all.
Programs used for rooting - AfterOTA 1.09, EUUS v3, blackThun3r A500 Manager
I have the CPUID, and SKB (I was somehow able to acquire those in one of my attempts to flash the stock rom)
What I don't know:
What version of Android OS is on the tablet. I'm pretty sure it has ICS, but he was deathly afraid of downloading any updates, even app updates even though I told him that all updates should be installed a.s.a.p. So there's a chance that it's still running HC.
Now here is my problem other than being stuck in APX mode. I have tried AfterOTA, it won't detect anything past Driver Installed on the Tablet information screen because USB debugging isn't enabled. So I can't use most of the functions of that program.
blackthund3r APX Flash v0.4 - Will get the tablet into the bootloader mode where it says:
Acer Iconia APX Mode in the upper right with a glowing yellow Acer logo in the center of the screen, nothing is flashing like the APX flasher says, I have reinstalled the drivers hundred of times with the same results.
Hangs at, "Flashing Bootloader (EBT) stage two - uploading image..."
EUUS v3 - Says, "Acer Iconia not detected"
(I had a screenshot posted here, but stupid forum limitations wouldn't let me. You could see what's going on if it let me post this.)
I do the reset procedure and it just goes back to the same message.
It will go into a screen on the tablet that says "Entering Acer Download Mode" Then EUUS tells me to do the reset procedure again, and this is a continuous loop that results in nothing being flashed. If I ignore that message and just continue nothing happens.
I also have a file called a500-hc.bat that runs nvflash and it gives an error that leads me to believe that a partition on the tablet is corrupted. Everyone says that EUUS v3 should fix this and flash back to original stock, but it obviously doesn't work.
Any help that I could get would be greatly appreciated. If you need any more information, just ask, and I'll do my best to get it. The tablet is (for lack of a better word) bricked, so I'm very limited on what sort of software info I can give you straight from the tab. Please Please Please help. And thank you in advance.
Tab is an acer iconia a500 8gb version running CWM, and HC bootloader. Last ROM on honeycomb was flexreaper but I forget version. I hadn't used tab in a while.
I wanted to let you know how I resolved it. I spent 2 days trying to upgrade to ICS bootloader and touch recovery. I almost gave up with a partial brick of a tab. I was no longer able to boot a ROM but could get to APX mode (sort of APX mode) where screen was black and power LED was on by using manual process. Hold in power and Reset for 3 seconds then release power while holding reset for another second. Tab would be recognized as APX mode device by the computer and flash tools but I couldn't get any of the tools to do the flashing. Blackthunder and nvflash failed with various errors. I found out after hours of trying this was not really APX mode. See below.
1. To fix USB driver issue. I had to install the Naked USB driver and Google USB driver from SDK package. All links found here on XDA. Only at this point did the tab show as a valid working APX device in devices and printers. Drivers still showed as unknown but worked. In Device manager was showing under USB host controller as acer usb recovery device or something like that.At this point I had all drivers installed. Acer driver, Google USB, and naked driver. I installed in that order until device was working on win 7 x64.
2. APX mode is described in some places as blank screen with power LED on but this is like stage one of apx mode. You still need the tool (nvflash or blackthunder) to get you to the point where the screen says APX mode in white font in the left upper corner and you are truely in APX mode. Use the auto process in the tool until you get there. My tab also had the word acer in large green font in the middle of the LCD when in true APX mode. I was never able to get to full APX mode using manual APX process on tab. This seems to place the tab in an APX ready state. Then you can use nvflash, a500manager, or blackthunder auto tools to get to full apx mode. Tab does a quick reboot or something and vibrates when going from APX ready to full APX mode with the screen going from blank to where it says apx mode in small white letters and acer in green large font (middle of screen). After I was in APX mode The only thing that worked was BABSECTOR or BADSECTOR tool to flash it. I ran the a501a.bat and then the a501b.bat inside the extracted folder to get ICS V8 bootloader and touch recovery installed. Once I used the BADSECTOR tool the process was quick and flashed in a matter of a few minutes. In 2 minutes I had completed what was going on for almost 2 days. Wow! I almost gave up. You can edit the script or just insert your SBK at the prompt.
I found the BAD or BABSECTOR process listed in a short post comment on another forum using google searches. There wasn't a lot of detail. Just the order of file use and that it it worked for someone who was having similar issues. You obviously need your SBK.
Hope this helps someone. Good luck!

Hi,
Thanks for your informative post - I had no idea there were different "apx modes".
Can you link where you downloaded your drivers in step 1 and the tools in step 2? If your method actually worked, some links would really be helpful.
Thanks!
Rich
