no, you won't be able to run adb whilst tab is in apx mode...if it is....check PC "safely remove hardware icon" Does the acer usb boot recovery driver show up here????

Do u see "acer iconia apx mode" or "entering download mode" on yr tab screen?

If the screen is black with no writing then your driver is not installed....you will need to force the install...and you will not get to "bootloader mode" until this is done...this is why you are stuck here...disconnect everything, reinstall acer drivers and reboot - then once you connect yr cable then windows should try to reinstall the acer usb recovery driver...Don't let it...instead install manually...

If u power yr tab down then boot up what happens next?

If you can still boot...d/l acer recovery installer from the forum thread in themes, apps or from the market...open it up and install your chosen recovery

regarding your cpuid, apxFlash wouldnt have let you get this far if it was wrong....so lets assume its ok until we find out otherwise....
[Acer Iconia A500] trakian:
here is the situation:

My A500 was under ICS 04.03 Thor (I think) It took me over one night and next day the A500 stayed on black screen.

Since, when I turn on my A500 I have a black screen with the power button on and nothing else. I install the official drivers ACER

USB_Acer_1.00.0524_A30H_A31H_A32H_A500_A501 Windows (I tried XP / 7) and then I connect my A500 drivers are installed indicating how ACER RECOVERY BOOT USB

I tried two different USB cables and multiple PCs If I turn my back on A500 and the A500 windows redetects

I feel that there are more OS / BL (I was under ClockworkMod) or Recovery. Finally to get the ACER logo and the inscription at the top of the screen Download mode, I have to use A500APXFlash.exe until reboot the system download mode.

then I'm the ACER logo, but A500APXFLASH stops (see my screenshots).

I tried with EUUs_SBK_Acer_A500_1.016.05_COM_GEN1 (which installs different drivers than those PICASSO ACER RECOVERY BOOT USB) and then it tells me wrong user ID and if I insist a second time it starts updating but stop at 5% about and nothing happens.

I tried USBDeview there is nothing in the same serial number with Afterota, like in the Windows Device UID does not mean anything.
[Acer Iconia A500] dibb_nz:
I see u r using this No i need used blackthund3r_A500_APX_Flash_Tool_v0.3-V3BL-CWM u might wanna try v6BL or v7BL apx package

Yr drivers are OK - there are 4 or 5 different drivers needed for the flash but u have the boot/recovery drivers so u should be good

Getting to apx mode is ok

I don't know why the flash will not work as u don't have any of the normal errors showing???

Try with the latest BL version see how u go, if that does not work then a rollback to HC is yr last chance, see jazzyjames tutorial how to do that

Preparing to try this guide

My a500 is running stock ics and stock recovery. I have rooted it. When I ran the root tool I didn't unlock the bootloader. I guess my question is, is it ok to run this tut without unlocking the bootloader first. Also I'm not sure if my tablet is in debug mode and have no idea how to check because my tablet doesn't boot past the acer splash screen.

Also i have tried running running the built in factory restore, reset button and USB kernal recovery upgrade

My A500 is stuck in APX mode. It happened after I improperly flashed skrillax_cz's ICS bootloader. it ran for a few weeks, then suddenly stopped. Now I only get a black screen with a lit power button. Every time I try what is in the OP, as soon as the tablet goes into download mode, the flash fails. Every time. I have loaded and reloaded the drivers, tried blackthund3r's APX flash tool (gets stuck at stage 2). I have the uid (had that in a nandroid backup, confirmed with usbdview), I have tried different usb ports, different usb cables. What could be wrong with this? I am beginning to think it is a hardware issue. I just hate to give up on this. Any suggestions?

[Acer Iconia A500] dibb_nz:
I've just posted a reply in thread apx flash utility...give that a read an see if it helps

....once u fail 2 complete the flash it can be a bit of a journey rom.get it working again....and that's the best case scenario....worst case scenario is fried chip on the motherboard entailing repair from Acer

you have 2 choices if my post doesn't work....but first.....

are u still on the hc bootloader?

what rom were u using?

can u still boot at all into anything?

if as u say yr tab suddenly went into apx.without any input from u, it.can only be a hardware issue....

if not, then there maybe some hope...

are u able to charge yr tab, if so do it right now....this is a priority

let me know how u get on

rgds

dibb

EDIT: @ Lucas....pls try not to multiple post...i know u want to.get fixed...but if everything i have previously suggested to u hasn't worked for u, then either u have a hw issue or you're not following things to the letter...

if a complete factory hard reset followed by either tdv4/EUU or bad sector doesn't work then yr tab is stuffedm

Unrooting A500

Here are the two references I followed to help me through:

http://xdaforums.com/showthread.php?t=1585907

http://xdaforums.com/showthread.php?t=1579490

I am definitely a noob that spent about 10 hours trying to revive my ACER A500. I basically ended up following the steps listed on the above forums (basically the same thing). Since some of it was over my head I will elaborate on a couple of steps I had to take.

My PC would not detect my TAB at all even when I tried to reset it (unless I was doing it wrong). I had never rooted before but had tried to install many variations of stock ROMS (using update.zip files on SD card) but none were working.

I also could not access my TAB to make sure the allow USB Debugging was permitted ... so I guess i just skipped this .... got lucky

Before I started, I downloaded a500_HC_3.1_FULL_update.zip and then saved it to my sd card (had renamed it update .zip)

The following steps are per TravisAntonio link above

1. downloaded the root-3.2.1-v4.7z

2.extracted it to hard drive.

3. i renamed the recovery.img file as suggested

4.When they said to download another recovery file I wasnt sure what they meant. I eventually just went into another Stock ROM file I had tried before (i think it was Acer_A500_4.010.38_COM_GEN1) and copied the recovery-from-boot.p file.

5. Pasted the recovery-from-boot.p file into the new Image Folder as instructed and renamed it to recovery.img.

6. followed this step. NOTE: this did not work for me a couple of times as I think I had the wrong CPUID. I did also try to open the PBJ20upgrade.exe file that was in there. I think this may have been the one that worked for me over the DotNetDetecter.exe ..... not 100% sure which one finally worked ... sorry.

7. follow instructions

8.1 followed. screen remained blank but could finally hear the PC detect the TAB. I had tried to reinstall drivers prior but nothing else worked.

8.2 ???

9. In order to get my CPUID I utilized the usbdeview.exe that is located in the USBTOOLS folder from the original root-3.2.1 file that was downloaded. It showed up as a serial number for my device. It did not show up for the current connection but was there from a couple of days prior? Anyway I took the only one that showed up and used that on the next screen (I may have had to add another 0 to the beginning).

That's all it took for me. it basically went through its thing and came back to life for me.

Thanks to everyone ... especially TravisAntonio for posting. I finally got through it because of all of you.
[Acer Iconia A500] dibb_nz:
Just a couple of things in case someone else tries to do it this way

this is usually becos a) acer and google drivers are not installed...in tdv4 there is a test.cmd, this will test your adb connection to make sure your tab and pc are communicating, there is also a folder containing an acer setup.exe which will install the acer drivers...b) if the drivers are installed then it can be a dodgy usb cable, try another one and also try a different usb port

normally you would enter recovery mode via voldown+pwr - and the update.zip 'should' flash automatically also note that the update.zip and tdv4 are two totally different methods of flashing and shouldn't be 'mixed' together....just remember to delete/rename the update.zip - you dont wanna accidentally find yourself back on gingerbread")

I'm amazed this worked - the instructions mean that you rename recovery.img to something else then copy another recovery.img to the image folder....the recovery boot p file is a file that overwrites a custom recovery image with an acer stock one - for anyone else following this you can leave the original recovery.img as is, its a custom cwm1.5 - not sure the reasoning behind changing

it at all -

phew!! hopefully you saw "acer download mode" or words to that effect, displayed on your tab!!

as long as the number you see has 15 digits you're all good , correct, you do need to add a zero to the beginning

awesome you made it through and got yourself fixed....and thanks for posting your experience

CPU ID?

It was all going so well but I got stuck at the CPU ID, where on usbdeview is it? i tried mostly everything on Acer A500 and the multiple drivers but nothing worked, there's only 1 serial number that I put a zero infront of but it's still a few characters short. Please help :( If it doesnt work is there any way to find the ID? My tablet is bricked at the acer screen and I'm pretty sure USB debugging is off.
[Acer Iconia A500] dibb_nz:
The only other way is via Linux there's a guide for that in general forum sticky

Power swith = new MB

I have an issue with my A500 where th power button broke off. Since I cannot get one, and there are mother boards available, how would I load a new mother board from scratch since those on e-bay say no OS installed.

Thanks,

Gary
[Acer Iconia A500] dibb_nz:
Not sure a new mobo comes with a new pwr button but there is a recent thread about installing a new mb. Also search here for broken pwr button someone else has repaired theirs.

Installing an OS should be the same as flashing a new ROM...stickys in dev forum should point you in the right directions
[Acer Iconia A500] jsimonson0:
If you order a NEW one from eBay, it will probably come with the OS installed. I got mine from "splus-outlet" for just over $50 delivered and it had the OS installed already. From there I extracted the CPUID and started playing around. What I noticed is that not all that come with the OS specify that in the description. Stay away from the used ones, you'll only save $10-15 and will almost certainly have to load the OS onto those.

Wrong CPU ID?

I used the linux method and got my CPU ID, in the right format and the right number of digits, but the EUU program still says it's the wrong CPU ID? do I have the wrong version or something?
[Acer Iconia A500] dibb_nz:
There have been no reports of Linux giving the wrong cpuid

Is it different than the one you got using usbdeview?

If the first 2 characters are 0x take them off.
[Acer Iconia A500] PattyMurph:
I never got one using USBDeview. that's why I had to use Linux, and if I take the 0x off then there's not enough characters?..
[Acer Iconia A500] dibb_nz:
Then its not your cpuid, i can't help with the Linux thing, but as I said before,

no-one that has used it has ever reported the cpuid it gave as being incorrect...

have you done a hard reset??? Sometimes this can jog your tab into life or at least get you past the acer logo
[Acer Iconia A500] PattyMurph:
If a hard reset is when you hold power + vol up and switch the lock then yes I've tried, it clears cache and userdata, and then goes back to acer forever.:(
[Acer Iconia A500] dibb_nz:
the hard reset is to remove the password so u can unbrick

Hello all, i got an iconia a500 and I think is bricked, My problem is not the one described here but i don't know where else to ask.

I was seeing my pictures and suddenly the tablet hang, so I reset it and now it doen't boot at all! When I turn it on ACER logo appears then ANDROID logo but nothing else happens. I've tried to boot pressing Power and volume- but a message appears on the top left corner that says:

"Erasing Cache Partition before SD ppdate...

--update_package=SDCARD:update.zip

Booting recovery kernel image"

After that an Android image apperas with a yellow triangle with a Exclamation sign appears the after a few seconds it reboots the ACER and ANDROID logos. Nothing more, nothing less. I'll try to make a video of it then upload it so you can see what I mean

TY . . . read your instructions. . . .

I read your instructions. I had hoped to find a file I could put onto a flash or SD, plug into Tablet and Hallelujah! The A500 is connected (micro). Not rooted. Purchased new, (of course just out of warranty) has profile link to Google, stuck on Google sign-in screen, won't connect to PC nor internet. Status bar indicates many things (pretty much everything), apparently was in middle of download when it got the "flu". Have attempted EVERY key combination including USB keyboard "esc" which changed the "lock" screen. Nothing responds, even the paperclip. Interesting to see you indicate the "pin" reset. I will be more than happy to donate if you can tell me: Where does the left hand go?, the right? And: Mode? Got no response anywhere. Can get to "safe mode", can get dead Android. 'Bout all other than and thanks so much. Kudos Oh, did download a bunch of files which I extracted and combined into one folder but it turns out is jibberish to me so never downloaded after first file said "oh, btw, this is out of date". Can you take a moment to explain a "new boot"? to me? Old as dirt, dumb asa rock. Thx again . . . .

Help With TWRP...

Hello forgive me spelling mistakes but I'm Brazilian and my native language is Portuguese ...

The doubt I have is the following ...

A few months behind I decided to update my tablet, I downloaded the latest version and compatible android and did the unlock, so far so good, everything went well (despite the difficulties).

I'm not 100% layman it had already done so in motorola phones (not a tablet) but in the end it worked ...

The problem is that after a month of use the tablet just did not start anymore, he fought on the home screen of ACER.

I tried several times and the result was always the same, there I decided to reinstall android, went into TWRP and did wipe the tablet, lost the operating system, but it was quiet because I thought I could install it again, copied it to my SD version of android I wanted there and the problems that came ...

I could not find my SD in the "browser" of TWRP, and so could not install the zip file that was it ...

I went into the folder named (SD-EXT) and also in the folder (SDCARD) and the contents of my SD card does not appear in either ...

I decided to research about unbrick because I thought maybe the method would solve my problem, but before doing anything I decided to ask to make sure I would not be doing stupid q ...

Is there anything I can do to install android again?

Could someone give me a hand?

You cannot proceed until the "bct error" is fixed. As far as I know, the apxflash tool by [MENTION=4518389]blackthund3r[/MENTION] is the only tool that repairs this error.

Once thats done, babsector will run fine. But. Not if the tab has a faulty memory chip.
