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.

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.

[Q][SOLVED] A500 bricked, stuck in bootloader. Won't boot kernel or recovery.

I am sorry to start a new thread but I have been reading threads and trying things now for over 7 hours straight. I have bricked my mothers A500.
I installed Skrillex V8 bootloader to my own tablet with Thor 1.7.3 recovery and a CM10.2 rom, everything worked fine. My mother liked how my tablet had way more battery and seemed faster then her own so she asked me to do it to hers.
I did everything the same except I had deleted the files and had to find a different bootloader so I found the "lightspeed" version of Skrilex V8 and as it seemed to just be a re-skin figured it was fine.
I downgraded to the unstable 3.0.2 build then installed iconia root and a Thor recovery via acer recovery. I then installed the lightspeed bootloader via thor with intentions of then installing the newer thor and rom after.
This is where im stuffed, after installing the new bootloader it is screwed. I cannot enter recovery or boot the primary kernal. I attempt to enter fastboot and although the tablet goes into fastboot it outputs errors and has random lockups and freezing on the tablet which the computer identifies as it being disconnected.
I have tried searching the forums for an answer and have tried everything I can understand but I am truely boned. As I am writing this I am installing packages to my Ubuntu laptop so that I can obtain the UID through the terminal in hopes it will work with APX and blackthunders tools.
If I cannot get it working I will simply wipe and give my mother my tablet, But I would really like to try and get this son of a ***** working again. I am currently incredibly annoyed at it and am probably missing something obvious. Please help me.
[UPDATE 1]
I have managed to obtain my CPUID and thus my SBK through the method described here -> http://forum.xda-developers.com/showthread.php?t=1751978
I am still unable to use any tools as my PC will not recognize it in APX mode, I have reinstalled the drivers, restarted, tried multiple USB ports, uninstalled the failed unrecognized device and started from scratch a few times and I just cant seem to get it to detect them. Also tried other USB cables incase it was iffy, checked contacts on ports. There also cannot be any env variable or reg conflicts as I used my diagnostic machine to check it and it booted into its clean OS.
the APX seems to work with my linux unit though, but the blackthunder tools are for windows...
[UPDATE 2]
Using the tutorial here ->http://forum.xda-developers.com/showthread.php?t=2444187
I made it boot into the APX mode with the yellow acer logo and the APX mode text at the top, however I left it for a while and it didnt seem to finish flashing, using lsusb I can see its still connected to the linux box but it is clearly not flashing properly.
I am going to leave it for a bit then try unplugging from linux and plugging into windows while in the yellow acer logo screen with verbose output and see if blackthunders tool detects it.
[UPDATE 3]
DO NOT try what i did in update 2, I believe i removed it when it was formatting the partition, it wont even boot to the bootloader now. black screen with white light on power button and cannot be detected as APX.
[UPDATE 4]
I treid a few more times at getting it into APX mode and it turns out its just being dicky and freezing randomly, however, by trying a few times (this is dangerous but i had nothing to lose at this point) to run the Nvflash script on my linux box eventually it run through and installed the v9 bootloader. This bootloader allowed me to go into Fastboot without the freezing or crashing or loss of communications i was experiencing before. I then using fastboot flashed a recovery appropriate to the v9 bootloader and am now using that to flash a 4.3 rom. This should completely fix all the problems.
I am now sure (as previously I could only guess that the problem was caused by a dicky install of the lightspeed bootloader (a custom variant of skrilex v8 designed to match the theme of the lightspeed rom).
[UPDATE 5]

Can you extract the partition 4 using nvflash --rawdeviceread to a file and share to me? My A500 is bricked and cannot download to it. only --rawdevicewrite works.
Thanks!

Please some one! I'm in dire need of help!

I have to post it here, because no one in the 'Android Q&A, Help & Troubleshooting' thread are replying anything.
Since I use to own an A500, I know how active and helpful the memeber of this thread are.
As there's no dedicaded thread for my newly bought Acer Iconia A210, I'm in dire need of you guys!
Here's my issue:
I was trying to root my device using this instructions: http://forum.xda-developers.com/show...5&highlight=up
Now I'm stuck at bootloader screen, with an acer logo and in left top corner is: bootloader version ISC-MR1-b05547a (unlock mode)
I can't communicates with tablet via USB (no device found) even I can't get to recover mode.
What should I do?

[Q] Bricked A500

Hello, I believe my kid had rebooted my tablet during an OTA update. I've been diligently reading page after page of posts trying everything possible to reflash this.
What I know:
- a500 16GB / win8 server / debian VBox
- a500 was rooted prior to OTA update
- can enter apx ( blk screen, wht power) and recovery mode (loads update.zip)
- I can get most recovery update.zip's to start, but so far, all have failed.
- A500 manager detects a500 in APX mode but states i need to install drivers. (repeated this many times)
- nvflash does not communicate (i'm thinking due to the incompatible drivers)
- "fastboot.exe devices" returns nothing- SBK and CPUID
What I don't know:
- the last version of OS on the a500. Maybe HC?
- if the device retained USB debugging before it bricked
- whether or not I installed CWM or other needed programs (was almost 3 years with no issues)
I have tried any images i can locate; mostly in the forums here. I'm not positive if I can just load them from SD, in recovery boot ( if the files are correct format) or if I need prior steps. I have tried every zip making sure it's "update.zip" although the contents of each are not always the same.
Any ideas or perhaps "guide for idiots" would be greatly appreciated.
Thanks!
edit: so I have located the CPUID and managed to find a working SBK calculator. Now I'm having issues related to .NET 2.0 when running the nvflash utility? I'll attempt an XP vbox to see if it's now due to win8.
new edit: the drivers don't seem to work on Win 8 or 7. I tried installing an XP vbox but I am not able to activate, therefor install proper utilities for the nvflash program.
It seems I'm stuck, unable to work around the .NET 2.0 conflict and the driver installation.
Perhaps I'll start looking at linux alternatives and hope someone could provide some more of an updated approach.
