[Q] Bricked Tab and need some help

Hello,
I was just sent this A500 today, and was given to me because it got bricked after supposedly being updated to ICS. I pulled the sd card and saw the update.zip on it, so I cleaned it out. I also tried to boot it up normally, and it hangs on the Acer logo indefinitely. Powered it down and tried to boot into recovery, and it has the stock recovery. I can get it into fastboot mode, but it wont connect to the pc for some reason. So I cant get the CPUID unless someone has a better way of getting this thing that I have yet to find. So, how can I fix this tablet?

Have you tried flashing the stock firmware via flashmode.

flashmode? First time I have heard of it after looking around. Im not going to lie to you, Im new to the a500 and the procedures here with it. So pardon my n00b like knowledge.

OK pretty sure this is what you wanna do http://forum.xda-developers.com/showthread.php?t=1516012
Edit- sorry just re-read your OP and seen u can't get ur CPUID....oh

Yeah... Im trying to see if there is a way I can get the UID from the APX mode or something... I can get the device into APX mode via the simple reset button, and have the flash tools and everything else, just need a way to get the UID or bypass it entirely. Still thinking.

This should be of interest for you: http://forum.xda-developers.com/showthread.php?t=1751978

That link was quite helpful actually, and I got my info I needed. Now Im trying to recover the tablet. Ive tried to use nvflash, but get a few errors each time I use it, an error 12 or something when it tries to flash the bootloader, and it stops from there, so I have a formatted tablet, lol. What Im trying right now is the EUU back to HC, so far so good, its been going for a bit now, not sure how long it is supposed to take, but we will see. What other tips can I start looking at if this fails for whatever reason/

The euu should not take longer than 10-15 minutes.

Well, what are some other options? Ill probably leave it for another 10 minutes for the benefit of the doubt, but I have a feeling it is stuck where nvflash has been getting stuck.

I think there is something messed up on you internal sd. Download BadSetor from my dropbox: https://www.dropbox.com/s/y3ty0l8xdzs1stl/BadSector.rar Extract it to your hdd. Get the tab in apx mode, and connect it to your pc. Run a501a.bat. When it succeeded, reboot the tab, and go in recovery. Go in "Mounts and Storage" and format System partition three!!! times. Wehen done, get tab again in apx mode, and run a501b.bat. When succeeded, your partitions on the tab are reformatted, and you have unlocked ics bootloader v8 and cwm 1.7.3 on your tab. Now, youre good to go to flash a custom ics rom.
Don't get confused by the filenames a 501a.bat and a501b.bat. It works on both a500 and a501, because they're using the same file system.

That sounds for me like a hardware issue. I think the internal sd is defective. Don`t know how i can help you further. I think you will have to send it in for repair. But maybe soeone else in the forum has still an idea.

Well,
I tried nvflash --bct flash.bct --setbct --odmdata 0x100c0105 --configfile flash.cfg --create --bl bootloader.bin --sbk 0xF0D21E00 0x6440D501 0x8B093103 0x647F2103 --go
I got to formatting the partitions before it errored out. At the moment, Im stuck with a softbrick, lol. So if anyone has any ideas, shoot em at me..

I had a couple of softbricks before. They are no problem to solve. But nvflash gives back that it can't write to the internal sd. And that sounds bad for me.

Well, everything was good (from what I hear) until the ICS update as far as everything goes. It just decided to not boot after the update. And thats where I left off.

[Solved] Bricked Tab
Well, I seem to have fixed it using a repetitive restart and nvflash until it gave in. Now im using Acer Recovery Installer, and we shall see how it goes from here.

Well, It didnt exactly work as planned, lol. Quick question as I try to refix this thing: Is there a way to work within the "download mode" instead of restarting everytime as far as formatting the partitions? Going in and out is a bit of a pain, lol

That i don`t know. Im only a user that g'bricked his tab a couplenof times and got it goin' again. Hope you'll get it working again, too.

[Q] A500 flashing fails

I am not sure of the best place to post this. I am having trouble installing loader/ROM on an Acer A500 tablet. I have read many of the posts here and in other forums and have tried several of the suggestions/guides. I think I am just digging the hole deeper and need some guidance on the path I should follow at this point.
The tablet is running Android 4.0.3 (Acer_AV041_A500_1.033.00_PA_CUS1), which has been completely stock and not rooted up to now. I followed directions on several postings (mainly by dibb_nz) on this forum, but have not been successful.
Here's how far I got and where I went off the rails.
I rooted it using SuperUser.
I collected the CPUID and got the SBK number.
I downloaded/installed Acer drivers and Andriod SDK.
I downloaded APX_v0.4A-flashTool-500Manager1.0.2_(1) and ran A500Manager and found that it could get info from the tablet.
I ran A500APXFlash, downloaded bundle 17, entered the SBK.
I manually put the table in APX mode, confirmed it is the Windows system tray (APX Device) and A500APXFlash reported it in that mode.
I proceeded to flash (in A500APXFlash). Here is where it went off the rails.
It hung at some point, but I can't recall exactly where (I've done many things since), but it was it was something like formatting the flash. I let it go for an hour and finally killed everything and rebooted the tablet.
I tried many more things, but always ended in failure. One was manual flashing with nvFlash. Below are the highlights of the batch file output to show how far it got:
Code:
Enter your SBK: <removed for security reasons?

During the above, the tablet said "Acer Iconia APX mode."
At one point I tried installing the CWM loader (I think it was that one). I also ran the Android adb program and was able to talk to the tablet through a command prompt.
Somewhere along the line, the Windows system tray driver report began saying "Acer USB Boot Recovery Driver" instead of "APX Device." I'm not sure when or what I did to cause it.
Another change in behavior is that the recovery mode boot (Power+VolDn) used to result in a dead robot icon. Now it looks like it is doing "SD update cmd: recovery" which fails (I put no SD card in it).
It appears that somewhere along the line (early in my trials) the BCT might have gotten wiped out and I cannot find a copy of it. I have seen various places where flashing hangs during a format or a download operation.
I have tried as much as I dare without help (maybe too much). At this point, by tablet is not bricked -- it still boots to Android 4.0.3. But I would like to restore it to where it was and then try the process again.
I have been trying to do the Timmy Dean EUU recovery to stock, but I have not been able to get the files. It seems that most of the links are either broken, or go to what lools like some pretty shady places. I'm not sure I should even be trying this route and, if I do, which EUU I should attempt.
I am fluent in Linux and have a Ubuntu 12.04 (VM) I can run if that's the best approach. I am also somewhat familiar with ARM Linux and the Marvell and TI-OMAP boot processes if any of this is useful. I am a complete noob on Android and the various ROMS, Loaders and mods. In fact, at this point, I'm not even sure what state tablet is in -- what loader is there, what has happened the flash ... -- or how to find out.
Thanks for whatever help/guidance you can give me.

[Q] ICS Bootloader installation on A501 with Linux

Hello.
Since I dont have 10 posts, I am forced to post here. I hope this is ok.
I already asked in a german forum, but I didnt get an answer there.
I have an Acer A501 Tablet.
Bootloader is HC 3.01.
Recovery is Touch Recovery 1.8.1 by Thor
ROM is 4.2.2 by TegraOwners
Since I want to try out the new 4.3 ROMs my bootloader must be upgraded to ICS Bootloader.
I am using Linux. And I want to use nvflash to replace the HC 3.01 bootloader with ICS v9.
I download the "Patched ICS bootloader V9" bootloader which contains 3 files:
bootloader_apx.bin
bootloader_v9.bin
bootloader_v9.blob
After studying the tutorials
for flashing:
http://forum.xda-developers.com/showthread.php?t=1622425
and linux:
http://forum.xda-developers.com/showpost.php?p=26372919&postcount=460
I still have a question. So forgive me to post here.
I have written an sh script which should do the flashing.
Code:
#!/bin/sh
./nvflash --bl bootloader_apx.bin --sbk 0x12345678 0x12345678 0x12345678 0x12345678
./nvflash -r --format_partition 4
./nvflash -r --download 4 bootloader_v9.bin
bootloader_apx.bin should load the bootloader.
bootloader_v9.bin is the bootloader itself.
bootloader_v9.blob I dont know what this file is good for.
So my question. Is this script right? I only want to replace the bootloader. Recovery and ROM is already installed.
I really need to know this exactly, since I dont want to brick my tablet.

Judging by the post u linked the script looks like this:
Code:
#!/bin/sh
./nvflash --bct bct.bct --setbct --bl bootloader.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk 0xXXXXX 0xXXXXX 0xXXXXX 0xXXXXXX --sync
./nvflash -r --format_partition 4
./nvflash -r --download 4 ics_boot_unlk_V3.bin
./nvflash -r --format_partition 6
./nvflash -r --download 6 recovery_thor17_403.img
./nvflash -r --go
Yr script is missing:
--sync command after the sbk and
./nvflash -r--go command after the v9.bin seeing as you aren't flashing a recovery.img. ...
I am linux illiterate! ! So cannot help you much, if at all but I think you'd be best to follow the post you linked to....hopefully someone else, (like @Moscow Desire, lol) can help you out a bit more!
Good luck

If you want to write a guide for linux, then you can create a new thread in general forum.

@Oberkellner - a guide would be great, as Moscow suggested start a new thread for it and I will add a link to it in the root guide, thanks

The code you ran, can be run with linux.
can you try it again please but replace the following:
odmdata 0x300d8011
with this:
odmdata 0xb00d8011
at the very end of the code replace --sync with --go
I've never tried doing it this way so you can play guinea pig, lol...don't worry it won't break anything thats not already broken
If that doesn't do it, then you will need to run the babsector.rar file, this will reset your partitions, if you get the bct error head over to this thread http://forum.xda-developers.com/showthread.php?p=47871344#post47871344from post#27. these guys are having issues too, u may be able to help each other

FWIW, I was able to muddle my way through an attempt to use NvFlash in Linux (Ubuntu). Took a while to get everything set up correctly, but once I did, even trying to get the partition table failed :crying:
I think I'm screwed

Lol no u not m8...babsector.rar file will repartition download in post 2 in the root guide....

While I greatly appreciate the ray of hope you're giving me, I've run BabSector dozens of times and it always fails at creating the BCT partition (or anything after that).

Judging by the post u linked the script looks like this:
Code:
#!/bin/sh
./nvflash --bct bct.bct --setbct --bl bootloader.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk 0xXXXXX 0xXXXXX 0xXXXXX 0xXXXXXX --sync

./nvflash -r --download 4 ics_boot_unlk_V3.bin
./nvflash -r --format_partition 6
./nvflash -r --download 6 recovery_thor17_403.img
./nvflash -r --go
Yr script is missing:
--sync command after the sbk and
./nvflash -r--go command after the v9.bin seeing as you aren't flashing a recovery.img. ...
I am linux illiterate! ! So cannot help you much, if at all but I think you'd be best to follow the post you linked to....hopefully someone else, (like @Moscow Desire, lol) can help you out a bit more!
Good luck

Well thankx for posting that...bct errors are difficult to fix, not impossible, just difficult. .
Blackthund3rs apxflash tool is the only tool I know of that can fix and sometimes even that tool can have probs too...
I dont know why this happens, but it does seem strange alot of peeps lately have struck this error.
As I stated in the other thread...nvflash requires the bct from your own tab...apxflash tool uses a default bct which in most cases works...but if it does not then you must dump yr tabs bct and use that. The tool provides an option to do this...as long as u are on Ics, rooted, have busybox installed and usb debugging enabled!!!
So, can u still boot?
Which rom were u running?
Can u boot to recovery?

Can't boot, to Android or Recovery, was running a custom HC 3.1 ROM called Minimalist because anything after 3.1 broke the app needed to stream from Hava Monsoon (slingbox-like device). Was rooted, had CWM installed, and I do have a backup with a mmcblk0_start.img, which supposedly can be used to decrypt and recreate a .bct file but I'm not sure how that can help seeing as how my partition table is fubar'd and I can't write to partition 2. Needless to say, I wasn't on ICS, don't have busybox installed (not even sure what it is) but I do (or at least did) have USB debugging enabled.
Was the first part of your last reply directed at me? The part about stuff missing from the script?
At this point, I'm back to working in Windows. Tried linux and it didn't help or change the errors.

Hmmm... just contacted ACER for an out-of-warranty repair and they created an RMA and sent me a pre-paid FedEx label. I have my fingers crossed that they are getting a lot of bad memory/motherboard repairs and are willing to do it for free, as suggested in this post:

ahhhh ok you're on the HC bootloader, different kettle of fish!!!
Its a shame the OP never posted his tutorial or told us how he got round the problem...ggrrrr
You have 2 choices from here:
1) run an update.zip from your ext sd card, altho with all the mucking about we've done I'm not sure how that will go...theres a link for a HC3.1 here. Put it on yr ext sd. Then power/vol down and it should boot into stock recovery and flash.
If all is well, you should be able to OTA all the way to ICS
2) The other way is to use timmydeans v4 - its nvflash EUU which will upgrade you to HC 3.2.1 pre-rooted and cwm installed. You say that anything above 3.1 breaks an app you want, but gosh, 3.1 is Gingerbread, its ancient Surely there must be another way to stream???
Anyway the main thing is to get you up and running, see how you go with these 2 methods.
If the upate.zip works and you intend staying on 3.1, you will need root again, see the root guide for the iconiaroot file, then Acer Recovery Installer file to flash a custom recovery.
---------- Post added at 11:12 AM ---------- Previous post was at 11:07 AM ----------
@mylacuna OMG True....Good on Acer, I can see them getting a few more requests too...pls let us know how you get on with it

Thanks again. Think I'm going to go with the RMA.
FWIW, neither update.zip on ext. sd card, nor timmy dean's method would work, unfortunately. Stock recovery never boots (not sure if it's because something's cooked, or because I had CWM installed) and Timmy Dean's never shows a connection using the test.cmd script. I think that's because it's requires an ICS bootloader or something.
In any case, have a nice one, mate. You went above and beyond :good:

FWIW, as outlined in the previous posts, my Iconia was fully bricked... absolutely none of the tools available were able to re-format a corrupted BCT partition, whether due to hardware/memory error or what, I can't say, but I initiated a repair ticket and Acer repaired my out-of-warranty A500 for free, including shipping both ways.
So that might be an option for anyone who's having no luck with these other methods.

Kewlies good on Acer

[Q] Going Nuts!!!

Okay so this thing is driving me nuts! I have the A500 and it is stuck in APX mode. A buddy gave me this saying it was bricked. I would love to get it up and going! I have been from forum to forum and going nuts here. I really though I was going to be able to get it with the timmydean tool. But when I enter my cpuID its one number too long. CPU ID: 0x37C6205446015D7. I got this number from doing some trick on ubutnu. I have my SKB as well. Can anyone help me out. I don't know much at all about tablets and flashing roms on them. I used to have a Windows Mobile phone back in the day and did a great deal of making kitchens for it but this seems like a lot more steps. Is there a trick with the cupid on timmydeans tool? Thank you in advance!

alright I believe what happened is my friend had ICS, but while updating something happened and that's when he said it was bricked. So when I was reading some of the many millions of forums I saw some talked about using Timmy deans tool to go back to stock HC and start over. So that's what I was trying to do.

okidoki! got it
For timmys tool to work you need USB debuggign enabled on your tab, so if you cannot boot to ensure that this is enabled, you need to try another tool!!!
the babsector.rar works when tdv4 won't...it will reset the partitions on your tab, flash the unlocked bootloader and cwm. If there is an error please post the output....You will also need to flash an ICS or JB rom
dibb_nz said:
babsector.rar download here
How to use babsector -
Turn your tab off and put it in apx mode manually. Press and hold reset button, hold power for 3 secs after the light comes on and release it, after another second release the reset button. Your screen is black and the power light is on.
On your PC:
Download and extract the .rar to a folder on your PC
Connect your tab to your PC
Navigate to the babsector folder and click on 501 A.bat
On your tab:
Reboot into recovery power/volume DOWN - (closest end to the power button)
Go to Mounts and Storage Menu and
Format - System, Data, Flexrom, Cache
Then flash your ICS/JB rom, power off.
Go back into apx mode and run 501 B.bat
Reboot into recovery and do the wipes
Reboot!!!

okay, thanks so much, I will try this tomorrow morning and post the results. Is there a full working jelly bean rom for the a500 now? I know I saw some things were not working like WiFi or cameras... Those were older post though. Can you point me to where I can get a good ICs or jelly bean rom?

NOOOOooooooooo lol Well, glad I asked before continuing to go crazy with it... I have seen motherboards that are pretty cheap for it... LIke 50-60.00. If I change it out would that work? Well assuming that the board I buy is good and everything. I would like a tablet with GPS but really don't want to spend a couple hundred bucks on a new one at that time. Thank you for all the help you gave me

Another bricked a500...

Apologies for yet another thread. I've been through every "unbrick" thread and still not able to boot the tab. I'm starting to think it's time to recycle the thing.
So, I picked up my tab one day and it had powered off (bone stock on the latest OTA). Tried to boot up and never got past the Acer splash screen (multiple attempts). Tried to reflash via the sd card, and it failed. Now it only boots to the dead Android. Try to flash another rom (these are stock releases) and it hangs for over a day without completing. Now it won't get past apx mos, black screen with a power light. Tried to flash via nvflash using several automated methods, they all fail complaining of various errors that seem to be related to bad partitions. I run badblocks and get errors. Now, having gone through everything short, I go to euu. That also hangs on copying the image. I'm out of ideas. is there something I haven't tried, or am I likely dealing with s dead tab at this point?

Pretty much the same thing happened to me last night I stayed up all morning trying to fix it but I'm beginning to realize it's probably something in the hardware.. Odd there so many all about the same kind of time.. Mine was rooted and the only thing I can boot to is the first skrillax boot loader screen, or Acer screen..depending on what I did..guess its Tims for a new tab..any suggestions? Lol

I guess we can take the guts out and make them into picture frames?

I did the fix my Acer thing from the Acer website found out mine is out of warranty for sure but they got back to me with an email and a phone number and I called and talked to a girl who told me it would be 200 and $49 just to get it in the door for a repair. Needless to say I *****ed and moaned told her I was going to throw it in the garbage and she is now sending me a label for FedEx to ship it and they will look at it hopefully they will fix it possibly for free now lol so I'm going to be sending it off when I get the label. I've tried just about everything and it seems mine just isn't recognized very well by the PC. I wonder if I have the correct drivers

This is what I'd do, and this goes for anyone stuck on the acer logo or otherwise soft-bricked.
Run babsector.rar file.
This is the ONLY file that will give you an error that can be troubleshooted. NONE of the auto tools or the manual nvflash method will do this.
Once babsector has run, post the output and we can tell if its the dreaded hardware fault or not.
Download and instructions here http://forum.xda-developers.com/showthread.php?t=2049778
A great guide by kaijikun here http://forum.xda-developers.com/showthread.php?t=2450119
If you get stuck with the black screen with the power led light ON.
Hold the power button for 5 secs until it goes off.
Re-enter apx mode manually (i.e. this means using the buttons, don't use the auto tools, it won't work)
It also goes without saying, you need the acer drivers http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=3851 and the drivers from the android sdk, you can download a mini zip here https://www.dropbox.com/s/x98233x397wrzr1/Step_1_Drivers_mini_sdk_adb.zip
If you don't have your CPUID, there's no way of unbricking.
If you don't know what a CPUID is AND can still boot, read this guide here http://forum.xda-developers.com/showthread.php?p=25429111#post25429111.
If you cannot boot and don't have your CPUID you need to recover it using Linux, see srbeens guide here http://forum.xda-developers.com/showthread.php?t=1751978
Just to say, the whole unbricking process takes some time....mostly downloading everything you need. You will also need a fully charged tab, you can sometimes use 40-50% of your battery doing this. To be safe connect your charger and leave it there till you are done.
The other thing is your PC OS...there has been mixed success with win8 and 64bit. FOr best results win7, vista and xp work best. If you are linux savvy, you're in luck, no driver issues at all with this OS!!!
The only way you can not restore your tab to fully working order is if your tab has the faulty memory chip. And the only way to know if this is the case is to run the babsector.rar file.

Yeah same thing happened to my A500. But downloaded 4 files Because there was 4 to choose from.
I renamed the file, eg filename.zip, to "update" with no extension. Copied to a clean micro SD. Inserted the SD card. Held the volume down and power switch until tablet vibrated and toggled the screen lock switch on then off. Then sat and watched. The whole process can take 30 minutes and for a long time it seemed stuck at about 25%. I decided to wait and see. And it all came good.
My A500 was stock no root. Still is and seems to work better now.

This is what I'd do, and this goes for anyone stuck on the acer logo or otherwise soft-bricked.
Run babsector.rar file.
This is the ONLY file that will give you an error that can be troubleshooted. NONE of the auto tools or the manual nvflash method will do this.
Once babsector has run, post the output and we can tell if its the dreaded hardware fault or not.
Download and instructions here http://forum.xda-developers.com/showthread.php?t=2049778
A great guide by kaijikun here http://forum.xda-developers.com/showthread.php?t=2450119
If you get stuck with the black screen with the power led light ON.
Hold the power button for 5 secs until it goes off.
Re-enter apx mode manually (i.e. this means using the buttons, don't use the auto tools, it won't work)
It also goes without saying, you need the acer drivers http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=3851 and the drivers from the android sdk, you can download a mini zip here https://www.dropbox.com/s/x98233x397wrzr1/Step_1_Drivers_mini_sdk_adb.zip
If you don't have your CPUID, there's no way of unbricking.
If you don't know what a CPUID is AND can still boot, read this guide here http://forum.xda-developers.com/showthread.php?p=25429111#post25429111.
If you cannot boot and don't have your CPUID you need to recover it using Linux, see srbeens guide here http://forum.xda-developers.com/showthread.php?t=1751978
Just to say, the whole unbricking process takes some time....mostly downloading everything you need. You will also need a fully charged tab, you can sometimes use 40-50% of your battery doing this. To be safe connect your charger and leave it there till you are done.
The other thing is your PC OS...there has been mixed success with win8 and 64bit. FOr best results win7, vista and xp work best. If you are linux savvy, you're in luck, no driver issues at all with this OS!!!
The only way you can not restore your tab to fully working order is if your tab has the faulty memory chip. And the only way to know if this is the case is to run the babsector.rar file.

Same thing happened to mine
Exact same thing happened to mine. No recourse since mine was out of warranty but I complained about it on an Acer Forum and on their facebook page and within a couple of hours I was contacted and instructed to mail it in. I had to pay for the shipping charges there (like 12 bucks) but they shipped it back on their dime and it was fixed. From shipping to them to getting it back was about 2 weeks. I was ready to swear off Acer forever but they manned up and fixed something that was obviously a widely known defect since it's happening to many others.

Dear dibb_nz,
What if A500 A.bat is working flawlessly for me, but A500 B.bat is failing during BCT formatting stage:
Code:
Formatting partition 2 BCT please wait.. FAILED!
command failure: create failed (bad data)
bootloader status: partition table is required for this command (code: 0) message: nverror:0x2 (0x2) flags:0
Should you need any additional info, just ask me
Thank you in advance for reply!

Hardware failure?
a501A failed. Here is the script.. Is my a500 suffering from the same bad memory chip problem?

Sorry u both having probs an I not sure I can help but.....
 @SyavsoN so do u get an error with the first bat file? If not,
run the first one again
Enter recovery and do the wipes
Reboot recovery and flash yr rom
What happens???
@mheister and everyone else with bct error.
Apxflash tool is the only tool that can fix these errors.
Normally u can use the default bct when u get to that option. But if u have probs with the default then u must use the bct from yr tab. So choose the dump yr bct option.
Thats about all I can suggest for u guys atm,
If @blackthund3r is still lurking around here he may be able to help out with this!!

Try Acer dude, 3 users have had there's repaired by acer for free, even if they were no longer under warranty!!! It's worth a shot

Anyone know how to get in contact with Acer. I've looked around in their support website, but I can't chat with a support assistant because my tablet is out of warranty.
