Need to ask a few questions?

First off I would like to thank you TD and everyone for all the hard work you do help everyone!

I am writing because my husband's tablet quit working about 2 weeks ago while he was playing poker on his tablet.

So he shut off the tablet and tried to start it later in the day, but it would not boot up. So, he did and reset and nothing.

Then he did a hard reset and that didn't help.

Now we are in the process of trying to get it up and running.

He had never connected his tablet to his or any computer. He didn't have any type of backup for the tablet.

In order to get his CUPID we had to go through ubuntu and were able to get the CUPID, because his tablet was stuck in a boot loop. (Thank you eppeP in that ordeal!)

We've tried TD's program and tried to go threw the steps. With the older one we can get it to see the tablet on the computer and are able to put the CUPID into the EUU. Then when it starts trying to put everything into the tablet and the line starts turning green it get stuck about 15% of the way done, and then totally stops. We have even let it set for an hour and it doesn't do nothing after 15%.

We have rebooted both the tablet and computer multiple times and that's how far we get.

The computer usually takes a couple of tries of putting the tablet in APX mode before the computer actually sees the tablet and I am not sure what we are doing wrong if anything.

Or if anyone has any ideas of what we can try?

I have literally have been reading and trying different things people have tried and I am not having any successs.

Also when the tablet is connected and you are suppose to see what is in the tablet of the current version there isn't anything that comes up in this step.

I am just at a loss of what to do.

PLEASE Help!! I'm getting totally stressed and can't afford to send the tablet back to Acer. We are out of warranty as of July and just can't afford sending it to Acer.

Oops, everything that was in husband's tablet was stock. He's not sure of what bootloader, kernal, and etc. He just did updates that were told by the tablet.

I hope I hear from someone soon!!

Thanks!

there have been a few reports of tabs suddenly not booting, those who have, have had to return them to Acer as they've suffered some sort of h/w issue.

in yr case it sounds like the tab was stock, i.e. no custom rom or recovery installed. i think i'd be tempted to try a stock update.zip, JDGM3NT4L has a thread in General forum 'revert to stock the easy way'. you'll end up with stock HC, u should be able to receive the official Acer OTA to ICS.

also check srbeens thread re: sbk via tdv4 running the nvflash command via Ubuntu.this will reset partitions then load the unlocked bootloader and a custom.

recovery.

as far as yr current issue goes, barring h/w issues i would say the drivers may be at fault. u may want to uninstall them and stop windows auto install and choose let me install.... browse to the extracted TD zip and USB driver folder.

then check device manager for the acer-picasso boot recovery driver.

does yr tab display 'entering Acer download mode' before the green status bar?

what PC OS are u trying this with? win 8 and 64bit can be troublesome
[Acer Iconia A500] radarbill:
Need to ask a few questions?

Thank you for getting back to me so quickly.

I tried using v3 and v4 of TD's progran and that's what I am saying when trying TD's steps I get to where the tablet says "entering Acer download mode" and then the green status bar goes to about 15% percent and then stops.

Then we reboot the computer and also the tablet and start the process again, but with no luck.

We have 2 different computers we have tried this with. Mine had windows Vista and my husband's has windows 7, I know mine is a 32 but system, but not sure of husbands. We have tried with both computers and have had no luck.

When installing the driver I am the one who chooses which driver. And I believe v4 version has the setup.exe file in TD's program. for the driver I have gotten my computer to recognize the acer-picasso boot recovery driver when installing the driver myself.

As for going back to stock my husband has no problem with that. A working tablet is always better then a big paper weight...

If you or anyone else has any other suggestions I am will to try...

Thanks again.

[Acer Iconia A500] dibb_nz:
sorry yaje so long gettin back to u

... have a look in the cpuid threads OP, on my sig....and see lcd047's solution,

other than that, sometimes it's a matter of perseverance!! a combination of tdv4, the nvFlash tools and update.zips till something works....sorry can't offer a definitive solution but good Luck!

---------- Post added at 05:51 AM ---------- Previous post was at 05:27 AM ----------

just saw this......

try running tdv4 as a rollback to HC

to rollback:

run tdv4 BUT DO NOT connect yr micro-usb cable yet.

wait for the PC to scan for image version.

it won't find it, which is what we want!

you will then see a window saying it cannot detect yr tab with instructions on how to put yr tab in manual apx mode.

follow the steps and then connect yr cable and carry on...

see how u go with that:thumbup:

[Acer Iconia A500] Porkchops:
Same, just went through this entire thread because the link to V3 wasn't working, then found there was a V4, but neither links to V4 were working :(

I'm an idiot, on the first post, the link to V4 works just fine (http://depositfiles.com/files/c6pr69ri6)
[Acer Iconia A500] dibb_nz:
Its an old thread used to upgrade you to rooted 3.2.1 -

It can also be used to downgrade/rollback/reset partition table - from ICS BUT there's a slight difference in the steps you need to take to do that...and alot of folks have come to grief here - so for the downgrade -

after running the "test.cmd" which checks the right drivers are installed correctly - run dotnetdetector.exe - follow the instructions UNTIL

You see a window asking you to connect your usb cable and that the EUU will check you "image versions" If you are downgrading DO NOT connect your cable!!!

This will "force" the "cannot detect your Iconia" window and then give instructions to put your tab into "manual apx mode" - once you have done that you can connect your cable - enter your cpuid - then you'll see the green status bar and the "update" will begin - it should take no longer than 10 minutes -

Please be careful with this - if you muck it up it can take ages to get your tab running again -

This will WIPE internal memory and you WILL lose all your data and settings etc

I'm in the process of writing up a proper "rollback" guide in the meantime

you might wanna take a look at this for tdv4 download and this too

Prompt Operation System or Operating System?:confused:

Getting some wired errors...

"Your operation system isn't compatible with the upgrade application. Please download .NET Framework 2.0 or above from Microsoft web site: ..."

Operation System or Operating System?

BTW, I am running "root-3.2.1-V4" on Windows 8 32-bit client with .NET framework 2.0 & 3.5 enabled.

yes. windows 8 is a bi*ch with this.. i have been looking for HOURS and i have downloeded gigs of useless files trying to get my gen2 3.2.1 rooted im tired, i have work in a few hours.. grrr............. their is no EASY way?! windows 8.. not even compatability mode works..
[Acer Iconia A500] dibb_nz:
Try the v8 bootloader/cwm package - there's a sticky in dev forum by civato or the ones in my sig....get yr cpuid now while you're still on hc its a whole lot easier. ..The v8 uses nvflash. ..u may have same issues tho....so either find a m8 with a win 7/xp machine or use Ubuntu as no dot net or drivers needed!

If u do go the v8 route...you'll be able to flash a custom ics/jb goodness. ..it's the only suggestion I can offer u guys sorry:(
[Acer Iconia A500] animepix:
Ok, i will try that.. later after sleep and work lol but.. heres my info..

<i havent done this in a LONG time>

Android Build	: Acer_A500_7.014.01_COM_GEN2

Bootloader	: 0.03.01-HC

I DID Manage to get Afterota to work, but i cant figure anything out, ofcoarse i run the different bootloaders etc, stock then the custom one, but none of them seem to take, i get the nice little good screen on my iconia but i dont see any change and when i try to boot from a custom firmware it just well. the nice android logo with the X... idk what to do anymore lol im burnt out.. and for the OP's link.... not available in my country after i click on your adfly link.. please... pick another host >>;

P.S. all i need is to root it, and custom loader/recovery so i can put my old taboonay or something else on there... this was so much easier about 2 years ago >>;

thanks :3
[Acer Iconia A500] dibb_nz:
The only 'thing' you will 'see' is 'skrilax_cz v8 bootloader' boot screen.

Also volume up plus power button will boot u to the 'fastboot menu'.

AfterOTA is only for stock rom updated via OTA to ICS.

When u finish the v8 flash u should see the big white PASS on screen.

What you do next is most important.

1. Power off.

2. Boot to recovery

3. Enable /data/media toggle and wipe data and cache.

4. Flash your ICS/Jb custom rom.

Note: If u flash a stock rom it will wipe yr new recovery and replace it with the stock recovery I.e. The dead android. Then u will have to reflash the v8...again!!

5. Data wipe again especially if you've been having problems.

Also remember u you must delete the boot.p file....pls don't ask where or how to do this, if you've read the guides you'll know:)

Unfortunately the Op timmydean is no longer around, the thread is after all, close to couple years old. But there are download links to tdv4 in my root guide see my sig.

Yes, this tab has kept a lot of us up for hours on end at times but it's so worth it once you 'get' it!!!!

If you need further help just ask, no problem!

Download Help

I realize that this thread is rather old now, and I'm assuming that is the reason why all the download like seem to be broken now. Nevertheless, can someone re-post the download material needed for this root. I've tried all the links from the original post and non contain the proper download required.

Any guidance would be greatly appreciated!!

Cheers.

Hey guys. I was looking but I was not able to find how to update my android for A501, so I have recently rooted and installed this ROM to my A501 device. It works well, but I was wondering if my 3G will be still working? As A500 doesnt come with mobile, so i was thinking maybe the firmware doesnt also have this option. thank you.
[Acer Iconia A500] aabbz:
The part when i use test.cmd does not work.

I have only this "List of devices attached" with nothing after.

How to solve this ? How to have my serial number ?

Problem installing DotNetDetecter on Windows 10

I have acer Iconia A500 with 3.2.1. Found root-3.2.1 and downloaded to Windows 10 PC. DotNetDetecter won't install. I went to add feature to Widows 10 and installed Net Framework 3.5 (which includes 2.0) but an error stating Download Net Framework 2.0 or higher still comes up.

Broken links....... Cue Ads... No Thanks... PLe@se HeLp

I have the acer iconia a500 with HC3.2.1 I am unable to do much with it. It needs updated. I would like it to access google play. I would like to be able to use chrome cast, google home and other modern apps.

It needs rooted. It needs a mod. I am considering the THORMOD. I am running into dead-end after dead-end after dead-end. I could root the 3.0 or 3.1 all day. But this is 3.2. Please hook me up with some working and free, links or files for this version. This tablet is in near perfect condition other than being 8 years old. Kept in padded case with screen saver. I am NOT buying a new one just because tech companies love raping people. PLEASE HELP. After days of searching and trying, I am about to lose my mind. Thank you in advance to whoever is willing to read this in 2019 and still has the means to assist.

CWM

After rooting, tou can install thor's acer recovery, flash cwm and use the thor's recovery, just fine.
[Acer Iconia A500] Euclid's Brother:
Ya see... that's what I'm talking about.. if your able to flash CWM and it boots without the "Boot Verification Failed" message, then it can't be the 3.2 bootloader.

So.. is it locked with 3.2 bootloader (can't install cwm) or not?

Edit:

I've just looked over the process in OP. In step 13, you get the message "image LNX checksum" which is a solid indication that the old 3.1 bootloader is installed.

You then boot into recovery (cwm) and fix the checksums so that a normal boot will work. At this point the old 3.1 bootloader is still installed.

So, it comes down to weather the stock ROM overwrites CWM on the first good boot. If it does, then you would indeed have the locked 3.2 bootloader and you WOULD NOT be able to reinstall CWM.
[Acer Iconia A500] timmyDean:
Ladies and Gentlemen,

The 3.2 locked boot loader is loaded after you reboot fixing the issues. What I did was replaced the flash recovery in the tool with CW Recovery (so I could fix the checksums) because I tweaked their flash which fubar's the checksums. So, you reboot and run the itsmagic which fixes it.

Then when you reboot, ACER should copy back in the stock 3.2 recover because they do this automatically on every boot. The Linux startup runs /etc/install-recovery.sh which copies in the stock recovery on each boot.

So this should be the sequence:

Flash >>>> CW recovery

Reboot

Error >>>>> run CW itsmagic

Reboot

Linux >>>> replaces CW with stock 3.2 Recovery which should be locked

End result, if you want to keep CW Recovery loaded you'd have to put the system.img into your kitchen and remove the etc/install-recovery.sh (or modify it) so it doesn't install a locked 3.2 recovery and then build your system.img and replace the one in the flash tool.

Also, with the next OTA, it should fubar you just like it did on this (meaning OTA should still occur and if they send one that removes root, you'll be broken again). If you don't want ACER fubar'ng your build then I would suggest you rename their update tool so OTA's cannot load (I posted how to do this in this thread).

Again, like I said, we have a medical app that all I needed was to get SU so I can delete all the crap. I install root, remove all the games, updates, toys, internet, etc. and then install the medical application and then unroot it. Since my goal was NOT to leave the device rooted. I stopped and posted how to get the tablet rooted. I didn't build out the system.img because my system.img wouldn't be anything anyone would want. But, Chris in this post, tweaked the procedure out so you guys can get a fully rooted device all the time.

What really needs to happen is someone needs to figure out the key/button sequence to get the ACER into flash mode. Therefore, we could all just then use nvflash.exe program to flash. What I do on most other models is just put the tablet into flash mode and then call nvflash.exe to load my ROM. The tool that ACER has for flashing (which this procedure is based on) is using it because you can see it in the folder. So ACER is just flashing it. Most OEM's tell you how to put their tablet into FLASH mode by pressing buttons and how to flash using the nvflash.exe program. If someone finds out how to do that, please post it here and I'll use it to build a one-click root process. Until that happens, you'll have to just follow the steps, but it works.
[Acer Iconia A500] timmyDean:
Azuske , here's some things to check:

Normally, adb not working is an issue with the Windows drivers not installed. So make sure you install the adb drivers for Windows. Check the Internet for them and how to install if you're not familiar with it.

To help keep you from bricking your tablet, you have to get adb Windows drivers installed and working first. Then you can flash it. Yes, the flashing tool runs the Windows driver installer but the steps and the test.cmd do NOT account for that. So, you have to install the Windows drivers first and get adb working which then insures your PC is talking to the tablet.

When I wrote and documented this, I wanted everyone to get adb working first therefore it cuts down on the emails where people say it doesn't work.

Anyway, see if that helps.
[Acer Iconia A500] Euclid's Brother:
Thank you for the info.. This makes it much clearer about what it does.

APX MODE

To get into APX mode, you hold the reset-button in with a toothpick (have to press pretty hard) while you power up. Then it will accept the nvflash command. I'm not sure if all the nvflash commands are available. Obviously --create is, but not sure about ---read or --download.

So far, I havn't been able to send any commands, always get the "usb write fail 0x4" error, which is due to the SBK not matching. I'm not exactly sure how it's supposed to go, since our UID is only 8 bytes and nvflash expexts 16 bytes. I've tried pre/post pending 00's and tried sending just 8 bytes. Tried reversing the order, etc.. Can you give me a sample nvflash command that passes in the SBK?

Thanks..

PS. Can you also tell me how to switch a running A500 to APX mode? is it an "echo 1" into something in /proc?

CWM

I installed Acer Recovery Installer v2.53 after following Timmy Dean's+ CHRISHOHL mods. Currently, my tab recovery is CWM rev 1.3.4 by thor2002ro. Was able to back up current ROM.You can , also go back and forth between thor's and stock receveries( like before they "locked' the bootloader) Finally, i have noticed previously that if you are in CWM, the OTA's will not install, they probably require stock recovery. (protection againt Acer messing my rooted tab again!!!)

short answer: yes you can install CWM, which I downloaded from your post , once rooted.
[Acer Iconia A500] timmyDean:
Yup, if you have CW Recovery loaded and keep it loaded then OTA will fail because OTA requires the stock recovery. However, I think it will drive you nuts as it will keep trying to install it. If you rename ACER's tools for downloading then you wouldn't constantly be bugged to do an upgrade.
[Acer Iconia A500] JUGOMAN:
update

Thank you Timmy. I would like to know if there are acer updates.But...I will

not

update, unless I know root will not be lost/difficult to implement. I should have been more thorough before I updated to HC 3.2, and Acer should be...respectful of the owners of their products. After all, this is now my "toy" not theirs. ( unless they are willing to give them for free...je,je) Lesson learned. Finally, I cannot thank you enough for allowing me to "re-root" my Iconia. Great job

I also, understand that you are dealing with a "fleet" of Iconias, on a professional setting. The OTA'S notifications, will probably drive you to drink.... I am only dealing with just one. The prospect of a new OTA notification, will probably awaken my curiosity to "check whats up with this new attempt by Acer to mess my Tab..."
[Acer Iconia A500] qben88:
has anybody else lost root after rebooting? Any suggestions as to how i can root again. Im on taboonay 2.1 and everything works fine, i just lost root and the ability to boot into cwm recovery. I followed timmys method to achieve root on stock 3.2hc

UPDATE its a problem with taboonay 2.1 and setcpu. if anybody else is having the same problem with that rom just uninstall setcpu and you should get root back after rebooting.

"Download this file" is a link ;)

Has anybody managed to enable 3G after rooting?

I have uploaded files for 3.1 to /system and changed build.prop, but there are no APN section in the settings.
[Acer Iconia A500] chrishohl:
Thanks for the "Download this file" clarification. Now what are you mean by 3G and APN? Iconia A500 does not have 3G...
[Acer Iconia A500] JUGOMAN:
3G

This tutorial is for acer iconia a500 not a501.
[Acer Iconia A500] VicDeo:
yes, but it is possible to add 3G support for USB modem for the stock 3.1.

I tried this way on rooted 3.2 with no success

In fact the reason I rooted it is to have access to the build.prop file and the /system catalog
[Acer Iconia A500] chrishohl:
Now I see, well I have never done that I don't have a usb 3G modem so I can't help you with this.

However I am sure that somebody in other threads may have the answer.

Good luck, sorry I can't help...
[Acer Iconia A500] VicDeo:
I have found the reason with dmesg.

The kernel modules usb_wwan.ko and option.ko that are required for 3g modem are incompatible with stock 3.2 (it has v.2.6.36.3+ kernel) :(
[Acer Iconia A500] comnam90:
sorry if this has been answered, but will superuser work once i have done this?
[Acer Iconia A500] chrishohl:
Yes it will.

I recommend (if you root) after the rooting process to update superuser via market and then update su binary via superuser's update function...
[Acer Iconia A500] comnam90:
tried this, but when it updates binary it fails on the "gaining root access" part?

But i know root is available because in terminal emulator i can access su....
[Acer Iconia A500] chrishohl:
It seems to me that you did not follow the how to http://www.chdcomputers.gr/en/mnu-kb-en/mnu-kb-android-en/mnu-kb-android-devices-en/mnu-kb-android-a500-en/254-art-kb000005-en correctly especially step 26 and forward. This is because the su binary that timmyDean uses can not be used with superuser app so from step 26 and below we are replacing it with another version.

Let me know if this helps...
