[Q] Bricked A500: partition table invalid

Summary: I tried to install the ROM that shouldn't be named over FLEXREAPER extreme, and now the tablet is bricked.
Previous state: A500, unlocked ICS bootloader v7, Thor recovery 1.7.3, FLEXREAPER RF1 EXTREME revision 2.
What I did:
I entered CWM recovery
I wiped data, cache, dalvik cache, and battery status
I installed Tegraowners ICS ROM v169
I installed gapps-ics-20120429 (without rebooting)
I rebooted the tablet.
In retrospect, I suppose things went wrong when I didn't reboot before installing gapps, but it's too late to change that now.
Current state: the tablet won't boot, and pressing vol-up / vol-down doesn't help.
Connecting an USB cable from Linux, I get the USB ID 0955:7820, so the tablet seems to be in APX mode. I tried flushing the boot loader from scratch, but the operation fails:
Code:
./nvflash --bct bct.bct --setbct --bl bootloader_apx.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX --sync

The above bootloader_apx.bin is ICS v7.
Edit: I do have a CWM backup taken just before installing the new ROM. So I suppose what I'm asking here is, how can I get to a bootable state with CPUID, SBK, the beginning of mmcblk0, and a working nvram. Help please?

If u cannot get to fastboot volume up/power to flash a recovery
and cannot boot to the OS or recovery
U will need to downgrade back to HC. See jazzyjames rollback thread on how to do that.
Yr cpuid is listed above as 'chip uid'

Ok, solved
Thanks for the answer. I got it working with TimmyDean's tool in a roundabout way: I re-created the partitions with TimmyDean's bootloader, and that allowed me to flash the unlocked ICS bootloader and recovery. Then I rebooted into recovery and I was back in business.
I should note however that I lost all the data from the internal sdcard in this process. I'm not sure if that was the result of me futzing with nvflash, or if re-creating the partitions did that; the end result is all files are gone. That's a pain, but survivable. At least my tablet is back, which is good, because with that rounded shape it would have made a lousy door stop.

Sounds like you are stuck in APX mode. A little reading will straighten things out.

badly needed help
could someone give some links to fix this problem i dont have my cpu id and sbk, EUU stop working in my laptop, apx tools are not working could someone help me im badly needed some help w/ this matter tnx for thos who help me

I have the exact same issue.
Power button turns white - screen is black - no vibration from power button - seems dead.
The tablet was untouched and stock - I have never rooted anything or messed with any ROMs.
It had updated to ICS a while back and was working great until yesterday when it just wouldn't turn on besides the power button.
I have tried holding down the volume up and power button reset. I have tried the reset button. I have tried unhooking the battery.
After checking this forum I have installed the ACER drivers and plugged the tablet into my PC. It is showing up as APX.
I believe I am stuck in APX mode so from what I'm reading there is hope I can somehow salvage the tablet even though I didn't try flashing
anything and haven't screwed with it before.
Since I have never messed with flashing android stuff I really have no idea where to start as the guides seem to be for people who have experience. Where do I start? From what I'm reading I'll need a CPUID but how do I get that from a "dead" machine.
I am a quick learner if someone has the time to point in the right direction. Maybe I'll get hooked on flashing ROMs and can contribute something here.
Thanks for any help you can give.

If yr tab is stuck in apx mode, you're gonna need yr cpuid to recover it, there is no other way....see cpuid guide in my SIG and checkout srbeens method using Linux to retrieve it or usbdeview....
If getting stuck happened spontaneously it points to the faulty chip issue requiring replacement from Acer... check post #3 of the root guide in my SIG for ways to recover from apex mode, you might get lucky but be aware that if its happened once it will happen again...

Thank you for the info. I was able to get my cpuid and sbk last night following the guide that used Ubuntu live cd. It was fun to play with Linux again.
I want to try and recover and if it continues to be a problem I will replace the board.
Looking at post 3 from your guide it appears my next step will be to use nvflash.
I am a little lost on what I will be flashing since I don't have anything backed up (flash a recovery?) and don't have a custom ROM to flash.
I just a need a push in the right direction.
Thanks for the help.

Well done getting yr cpuid!!
If you want stock, your best bet is an Acer EUU. There's one in the guide which will take u back to HC 3.0.1. Blackthund3r has one in his acer OTA update thread too I think in dev forum....
Next step is getting out of apx mode...use lcd047's method in the cpuid guide....just use the image folder from your EUU ...and no need to do the boot loader part....Also use Linux again to run nvflash commands, no driver issues with that, unlike windows....
See how u go with that for a start. You should be able to OTA all the way to ICS with that EUU, if u want.

OK bad data and partition error too...
Which EUU did u end up using?
tdv4 is known to reset partitions but in some instances fails. The babsector.rar file can be more successful... link in the root guide with some instructions how to use.
You're gonna need a ROM to flash and At this stage I'd suggest a custom ICS one...
babsector will/should also flash up the skrilax_cz v8 unlocked bootloader.
If u get still get a bad data error then yr tab is toast...BUT keep trying it 8, 10, 15 times you may get lucky
PS:
Oh check the euu image folder for the .bat file and see if the odm data values match with what u are using manually.
There are 2 values used in different euu's and no-one as ever explained why this is....the one u used and this one 0x300d8011
To leave download/apx mode the windows command is nvflash -r --go
See vaches post bottom of post 3 in root guide, for more nvflash commands. You might just get lucky
good luck!!

I used this EUU
Official Acer EUU 3.0.1
WHOA!! Something happened overnight. When I went to bed last night I was stuck in APX.
I was going to try a new EUU or babsector like you suggested. As I was getting ready to do that I powered on the tablet. It vibrated and the ACER logo came up on the screen. First time it has done that since I started trying to fix it. It does not say it is download mode like it did before.
Looking at the guide there is a section that says
Use this update.zip for any of the following:
- You do not have your cpuid
- You are stuck on the "Acer" Logo
- Your tab boots past the Acer Logo but then boot loops at the boot animation
- You are on the old HC bootloader /ICS Rom combination
- You wish to return to factory stock, and OTA all the way to Stock ICS
Should I be trying that now?

I ended up trying the tdv4 EUU. I put the tablet back into APX mode.

Its not looking good m8
Someone else posted ebay have new m/b's listed for $50, you may want to look into that??
Couple of things to note though:
maybe just a copy/paste error but
you wrote: [email protected]:~/Desktop/root-3.2.1/Image$ sudo ./nvflash --bt --odmdata 0x100c0105
should be nvflash --bct flash.bct --setbct --configfile flash.cfg --create --odmdata 0xb00d8011 --bl bootloader.bin --go
the BCT error - if you d/l apxflash tool and run it....you MUST dump, save then use your tabs BCT when u get to the "bct window" - carry on with the tool and then put your tab in apx mode manually - just before the flash you'll see a window with a couple of check boxes "show nvflash commands'" check that to show any flash errors....flash it and see what happens
failure to write to mass storage - just another symptom of the "bad sector fault"
you might try a factory hard reset via rotation switch - this should wipe all userdata and cache and has been known to fix a few problems
With all the tools and some persistence (otherwise known as banging one's head against a brick wall. lol) something may end up working....thats all I can offer you at the moment...others who have been in this same situation will post something like you did...whoa all of a sudden it worked!!!! Be aware though it will happen again sometime in the future unfortunately...as I said before, your best bet is gonna be ebay

Well I tried for a few more hours to get something flashed and finally gave up and ordered a new board. Since this thing bricked itself without me ever screwing around with the file system I've got to believe it's a hardware issue. Hopefully the new board will last longer than 14 months like this one. Thanks for the tips on trying to revive it. After installing the new board I might get into some of this custom ROM stuff. What do you suggest for a ROM?

a500 USB DRIVER VANISHES
I need a little help my device is stuck in apx mode (blank screen with power led on) i have uid (cpuid) and sbk i have read a lot fom this forum and have all the tool to root, flash, load.. But my main problem is that when i reset my acer a500 and the usb is attached the windows 7 recognizes the driver and (sound pops up) and the driver (acer picasso usb boot recovery driver) is there but no tool e.g apxtool or fastflash or ics rooting nothing works or regocznies the device coz when i press any option or press the key to continue the drive drops and vanishes from the window usb list in device manager and i have to manually reset acer again to get the driver back but still no use as command prompt tells me that no device is attached or found. Please help as this acer is my wifes gift to me and im trying hard to get it back its totally dead

[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:

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] Vega clone flashing problem

Hello there, so it would appear that I've screwed up a big time. It's better if I tell you the whole story, so someone can help me.
I have this Vega clone with Froyo on it and I actually managed to delete the stock launcher with Titanium Backup. I though I wouldn't need it anymore (I know, I know) since I had GoLauncher installed. It worked well until I decided to flash a different ROM. So I formated the phone, erasing all the data, GoLauncher included. And of course I ran into a problem. I can't get past the Froyo setup wizard (probably because of the deleted stock Launcher), it just crashes everytime I try to finish the setup and returns back to the start.
After many tries I've decided to flash a Stock Vega ROM seeing as it should be compatible with my tablet. I put the device into APX mode, installed necesarry Nvidia drivers and tried to flash it with the exe downloaded from Vega homepage. And this is the main problem, the program works for a while and then it stops at creating BCT partition, showing this error:
C:\Users\LUK~1\AppData\Local\Temp>nvflash.exe --bct H5PS1G83EFR-S6C_V24_0625.bct

I've been trying to fix this for two days now and I'm getting desperate. I found several posts on other forums where some users had the same problem, but there was no solution posted anywhere.
Does anyone know, what may be the cause of this error and how can I fix this?
Alternatively, is there another solution to the problem I've created?

Does it happen with all nvflash roms ?
if yes see below, if no try one of Scannos roms first before proceeding below.
Can you unzip the nvflash.exe, any zip prgram should do this, even if you rename it to nvflash.zip.
Then edit the command to flash and exclude flashing the bct cause this looks like this is where it's falling down. Just use the other commands. For an example see below. The full command is first. So edit out the bct bit.
nvflash.exe --bct flash.bct --setbct --bl bootloader.bin --configfile flash.cfg --odmdata 0x000c0075 --create --go
Try something like
nvflash.exe --bl bootloader.bin --configfile flash.cfg --odmdata 0x000c0075 --create --go
See how you get on with that. And as usual I'm not responsible if your tablet blows up, goes on fire or whatever. You could try asking over on modaco or tabletroms forum, look for Scanno or EJTagle.
You could also try this.
Actually reading around I don't think you need to extract the nvflash.exe/zip but it's worth a shot.
Sorry about the long post.

Thank you for your reply Stephen.

Ok, so the full command for the stock nvflash is:

I've tried to get rid of all the BCT parts, but it doesn't seem to work even if I delete a single argument. Always ends up like this:
command failure: --setbct required for --create
or
command failure: bootloader download failed

No problem, you're the only one who has tried to help me so far.

When you unzip the nvflash rom can you send the config file please. Flash.cfg I think it's called.
This looks weird to me.

Looks like it's pointing in teh wrong direction.
I could be totally way off but figure it's worth a go.

There you go, hopefully you can find out what's wrong.

What kind of clone is it ? Is it a Gtab ?
Couple of things to try/read over at your leisure.

After this not sure what else to try to be honest. Either it's a bad block on the nand or a clone of the vega and the Roms aren't taking to it.
Is it a P10AN01 ?

take a look here

[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 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. ...

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

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?
Sent from my GT-I9300 using Tapatalk

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.

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.

@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
