Any chance to grabe cpuid after brick?

Hi guys,
after three days of reading and reading and many hands on - thank u all for all the usefull posts here - i need a definitely answer:
- is it possible to grab the acer a500 cpuid under APX Mode or not?
Scenary:
- tablet prompts every day for an update. My friend at last accepted it and then the reboot came and then some problems like restarting, crashes, etc. (I suppose a simple hard reset would fix it and he'd have a clean and workfull update. But he took to a assistence shop near his home and as i can figure it out they tried to flash it instead cos stuck in android after acer splash. And if tried to go into recovery mode only a layed down droid with that red exclamation.
- in my turn first tried to grab cpuid as i read here - thank u all - but all i got 0123456789ABCDEF. Then tried to flash with an update.zip grabbed from some rom version i cant remember after such many readings... No longer, sorry - and after updating completely the TABLET CONFIGURING screen comes out then reboots and BOOT VERIFIED FAILED. I tried also others update.zip but this one is the only one wich can "works". All the others one i tried stop around 33% and the droid lays down again.
That´s why i need an answer to my question cos i think it´s the only way to have a succesfull flashing via APX mode. Am right?
After so much brain stormings i have seen around here about this issue will someone still try to gimme a help?
Thank u all in advance.
Rgds,

If the device is booting into APX mode you should just need to do a read of 8 bytes, this should give you the UID.
I posted some C code for doing this with libusb before.

And this should be posted in Q&A.

help

So I have the acer a500 with the stock ics and rooted. i was using my tablet just fine last night and later on went to use it again and now its stuck on the acer screen. i have tried the resets for recovery aND IT does not work. its still stuck on the acer screen. can anyone help me? please. my tablet is the gen2 when i received the ics update if that helps. and as mentioned it was fine until last night. is there a way i can reinstall it with the sd card? i would love the stock image if possible.

Wrong forum section.

Download a stock acer image and place it on a MicroSD under the name of update.zip then boot into recovery
But yes it is the wrong forum section - should be in Q&A doesn't bother me too much but it irritates devs because it's the development forum

I'm not sure what may have happened but the easiest way to fix your tab is to downgrade back to HC using an acer utility called an "EUU". you will need your cpuid for this so i hope you have saved it somewhere.
Look here for 'jazzyjames' tutorial How to rollback to HC - for instructions on how to do this and a link to timmydeans HC EUU - also take a look thru my cpuid post (link in sig) for loads of info and links and even how to get yr cpuid if u dont have it

thanks i tried it and follow instructions numerous times. evry time i get to the step where it says "entering acer download mode on my tablet" on the EUU program on my laptop it says it "failed" so i try and try again with the same results. im running out of options. i dont know what to do.

maybe give this a shot. I've never had to use it myself but it's probably worth a shot.
How to unbrick your tablet -
http://forum.xda-developers.com/showthread.php?t=1699277

oh heck that doesnt sound too good, i've not heard of the actual EUU "failing" guess thats the result of the usb issue you spoke of!
The "update.zip" method, you have 2 choices here See this thread for all the Official Acer Stock Roms - Ensure you download a "Full" rom and not just one of the update packages....instructions are in the first post...
You need to extract the update.zip and it may need to be decrypted as I said instructions for all this are in the OP!!
method2 - I've tried this once!! I got pretty frustrated real quick. Its a buggy chinese rom - took me a good hour to finally get into flashing a recovery, but it did work and plenty of others
have posted success with it... drkalo has a guide right here
Failing that m8 yr options are very, very few...
Try on a different computer so we can rule that out...or not!
or try to troubleshoot the usb issue....there are the only 2 ways via sdcard or pc/usb...
thinking about it now, in your post you said
"i cannot use usb because my computer wont read it not even after downloading drivers. anyone help me please?"
Not sure I follow, wouldnt have thought you'd get all that way to download mode without USB drivers to begin with.
You have debugging enabled in settings and you connect your cable to your pc but your tab does not show up on your PC in Device Manager???
Are you still on the stock bootloader??what about recovery??

this is what comes up
this is what comes up after trying this methid

So this window that pops up saying 'failed' and with instructions to go into apx mode - did u do this? what happened after you did it?
I haven't seen this particular error but normally with the downgrade process you do not have yr tab connected UNTIL you see the "cant detect your iconia tab" window (with similar instructions to enter apx mode manually) did you see this window at all? you do not enter your cpuid until AFTER you have put yr tab in apx mode and connected to yr PC, then the green status bar shows and then you should see "Congratulations".
To check you are in apx mode your tab screen is black and the power light is ON.
Now before you connect yr tab to yr PC open up Device Manager (pc) so you can make sure the apx/usb driver loads when you connect the cable - it will show under "USB Controllers". Once you can confirm the drivers are installed then you should be all good
The drivers are a bit of a pain as there are different ones for each different 'mode' of your tab i.e
USB driver that allows you to see the contents of yr tab from yr PC
ADB driver that allows yr tab and pc to communicate by sending commands to yr tab via yr PC
APX Driver which you normally only see while running HC, but yr PC can sometimes report an error with the "apx device" if the drivers have not installed properly
Acer Boot/Recovery Driver which NEEDS to be installed for any type of nvflash or EUU flash to be successful
Fastboot Driver if you have flashed bootloader v3 up this driver will load when you enter "Fastboot"
This is why folks have trouble with drivers and why we keep telling them "reinstall the drivers!!!" The Acer drivers from acer support AND the Google adb drivers which you can get from the first post of my cpuid thread (link in sig) the zip also has the fastboot drivers and saves you having to download the full android sdk. Having device manager OPEN while attempting any type of flash definitely helps you see whats happening - or not - driver wise...

TF101 "bricked" and I can't restore it

Hi !
I am posting here because I'm a bit desperate.
I have a B40 TF101 and a B70 dock (I bought them separately).
I have tried to flash an official ASUS update downloaded from their website using EasyFlasher.
The thing is it did not work and now my tablet won't boot at all.
All I can do now is start APX mode. The wieird thing is that it does not work with every computer, some detect my tablet and some just don't. Note that it only works while the dock is connected. Without the dock, I can't get the APX mode to be detected on any of my computers.
On the only computer that detects it, I have tried pretty much everything I found on the web to restore a rom, using easyflasher again on windows, then juste wheelie's restore.sh script under linux.
Using easyflasher I can't download the complete rom (it stops at uploading blob.APP, saying that a timer has expired or something like that). I tried to simply install a custom recovery image, to be able to flash an update.zip from there. The flash process seems to go as expected but I just can't reboot into the recovery, the tablet only boots into APX mode.
I am really stuck there, and I hope someone among you will be able to help me or at least tell me there is still hope
Thanks

If you aren't getting many replies here, I would post this on the Q&A section.

You need an NVFLASH rom
even if it doesn't seem to have detected APX mode try it anyway

You have to install the apx mode drivers for your device in order for it to be detected by the computer plenty of tools available to recover your device just search for some good ones will even install the apx drivers for you for example this tool http://forum.xda-developers.com/showthread.php?t=1185104

tf101 bootloop, corrupt recovery, apx inaccessible. lend me a hand?

ok so i have a pretty big problem and very minimal experience with flashing and rooting. Reading and studying many many forums i have peiced together what i have done wrong to do brick my tablet. So to begin a few days ago i managed to wipe my stock recovery and flashed a non existant one, reason being is i didnt download a recovery and unzip it in the required folder. the following day i had it rooted, that was successful. i installed an app from the android market which required root access and a reboot. It is now in bootloop on the "Asus Inspiring Innovation Persistant Perfection" Recovery results in the "Dead Andriod" screen. i have tried flashing using easy flasher but i cant get into APX mode to do so. if i exicute apx mode and plug the usb into the pc i dont get a response, but if have the cable already plugged in and exicute apx i hear chimes and i get "win 7 apx drivers not installed" i tried easy flasher and successfuly flashed WW_epaduser9_2_1_27UpdateLauncher asus stock rom however it still stuck in bootloop. i tried the recovery feature that came with easy flasher but that still result in bootloop when i boot from recovery. i have tried many recovery mods and none seem to work. im doing something wrong i just need someones help getting me out of this i dont want to make anymore mistakes. i have done enough damage. im taking this as light as possible, im a noob i watched the xda noob video and i read a t101 guide on a thread here on this website. many thanks for caring about a strangers issues.

Try this:
Open page with EasyFlasher
Download EasyFlasher
Restart your device into APX (power off than power on while holding volume up - screen will turn black and it will look like off)
Connect your tablet to windows computer. If you already have APX drivers just continue with next step. If don't, windows probably show you info that they didn't find proper driver. Just download APX driver (link on Easy Flasher page), open device manager on windows, right click on APX (it will have exclamation mark next to it) and choose update driver and select manual location to location where you extracted apx drivers.
Download the latest ASUS stock firmware (link also on Easy Flasher page)
Choose Flash Asus stock zip / Unbrick and select location of downloaded stock
When finished, click on flash button in Recovery area.
reboot and pray

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.
