[Acer Iconia A500] Skrilax_CZ:
So, same thing happened to yaworski, and we figured out on gtalk what's going on and how to get around it.

First, by checking rawread / rawwrite commands, we figured out that it's faulty eMMC (in his case), causing nvflash to fail formatting it as a BCT partition (see nvflash --help and "rawdeviceread" and "rawdevicewrite" commands). If you're more experienced, you can use them to figure out where it fails, if it's not the first sector, then you can use the workaround (in yaworski's case if was somewhere around 200 - 300 th sector (4 kB per sector). Open up the flash.cfg file with configurations for the partitions, you should have something like this in there:

[partition]
name=BCT
id=2
type=boot_config_table
allocation_policy=sequential
filesystem_type=basic
size=3145728
file_system_attribute=0
partition_attribute=0
allocation_attribute=8
percent_reserved=0

[partition]
name=PT
id=3
type=partition_table
allocation_policy=sequential
filesystem_type=basic
size=4096
file_system_attribute=0
partition_attribute=0
allocation_attribute=8
percent_reserved=0

in which you're wasting 3 MB on BCT which is in fact less than 4 kB, so reduce BCT size to 4096 and a dummy FCK partition over the "bad area"

[partition]
name=BCT
id=2
type=boot_config_table
allocation_policy=sequential
filesystem_type=basic
size=[COLOR="Red"]4096[/COLOR]
file_system_attribute=0
partition_attribute=0
allocation_attribute=8
percent_reserved=0

[partition]
name=PT
id=3
type=partition_table
allocation_policy=sequential
filesystem_type=basic
size=4096
file_system_attribute=0
partition_attribute=0
allocation_attribute=8
percent_reserved=0

[COLOR="red"][partition]
name=FCK
id=15
type=data
allocation_policy=sequential
filesystem_type=basic
size=4194304
file_system_attribute=0
partition_attribute=0
allocation_attribute=8
percent_reserved=0[/COLOR]

After that, the --create command (with --odmdata specified) should work (or at least worked in yaworski's case).

nvflash --bct flash.bct --setbct --odmdata 0xXXXXXXXX --configfile flash.cfg --create --bl bootloader.bin --sbk 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX

In the flash.cfg, I recommend removing "filename" attribute for every partition except EBT, and in EBT use ICS patched bootloader (which has fastboot), you can however specify recovery for SOS partition.

When the repartitioning finishes, dump and decrypt the bct from the tablet, then send "nvflash -r --go" to see PASS.

Anyway, several notes:

A) yaworsky used 40960 size for BCT, we weren't trying 4096

B) if the second sector is fauly, put the FCK partition between BCT and PT

C) expand the FCK partition to more than 8 MB (it's 4 MB in the sample config, su double it), if you are stuck in APX mode even after you flash the bootloader (faulty blocks over EBT).

D) if the first sector is faulty, then there is no go

The are no issues with the ROMs, as kernels will skip the FCK partitions (despite it's marked as data ufffff) In any case, as this is an issue with HW, I still recommend returning it for warranty, as it'll happen again sooner or later.
[Acer Iconia A500] lcd047:
This finally starts to make some sense, thank you. Can you please give more details about what you did?
[Acer Iconia A500] yaworski:
@lcd047: all we did was just changing size of BCT partition and adding another dummy partition in a way, that the faulty sector in eMMC was inside of that partition. That way nvflash is able to properly format BCT and PT partitions and whole --create operation is also successful (at least in my case was).

I was using EUU files from Image folder. In addition I've put there Skrilax_CZ's bootloader_v8_blue.bin and set this as filename in flash.cfg for EBT partition. All other filename attributes were removed.

Then you just need to make changes to flash.cfg as described by Skrilax_CZ above (red color shows changes in flash.cfg that needs to be done).

The way I've found where is the eMMC damaged was writting content from mmcblk0_start.img file (from Thor's CWM backup) using raw write (place the file inside nvflash folder before). If the eMMC is really faulty then write operation will just hang at some point (in my case it stopped at byte 1179648 - but this is not the faulty one, it is after it). If the write stops just use ctrl+c to exit nvflash and reset tablet by holding power for 5 seconds or use reset switch.

nvflash --rawdevicewrite 0 1664 mmcblk0_start.img --bl bootloader.bin --sbk 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX --go

And then read it back:

nvflash --rawdeviceread 0 1664 test.img --bl bootloader.bin --sbk 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX --go

Use some tool that can show differences between two binary files. I've used Total Commander to do that and just found the first difference and it was at offset 0x100000 (1048576 decimal) which is exactly 1MB.

BTW if you don't have backup of mmcblk0_start then just use any file that is at least 6815744 bytes long. It doesn't matter what the file is as the tab won't start anyway if the chip is damaged without using modified --create command. You can even use some mp3 file :). This is just needed to find the first difference between the original file and the one read back from eMMC.

Hello,

I have a big problem.

When I run A501A.bat, it creates some partitions and format 4 partitions. The blank screen of the tablet shows acer logo with Acer Apx Mode in white and after that nothing happens!

If I reboot the tablet, I can't go to recovery.

I don't know the tablet's story because I bought it broken. The tablet stucks in Apx mode.

(I am sorry for my bad english)

D) if the first sector is faulty, then there is no go ... “

I've been following this thread with interest just because I'm in a similar situation with my A500. From the quote above, my questions are:

(1) If the partition table was damaged completely, is there a way to rewrite it anew apart from the aforementioned procedures - all of which which I've tried without success?

(2) If part of the internal storage reserved for ROMS is damaged, is it possible to manipulate the files in the folder “Image” of TDV4 or the NvFlash executable itself to command the creation of, say, the BCT partition somewhere else?

I assume not the whole storage in my tablet was ruined as it still shows three different Acer logos (yellow, white and “Iconia Tab A500”) with the indication of either APX or Download Mode in white letters on the upper left corner upon flashing the bootloader.

For clarification: I used the V8-UNL-ICS-HC-bootloader-MULTI-cwm package which has a part-table.cfg indicating BCT partition starting at sector 0. This is where it gets stuck, hanging on “NVFlash starts” forever. Prior, it indicates “bootloader status: failed to create the partition...”

Any input is greatly appreciated.

Note: Sorry but I'm not sure how to include pictures in here. My original text has them, but upon pasting, they vanished. It would be nice if someone could show how to upload pictures.

I can't rule out a first sector issue as I haven't figured out how to get nvflash --rawdeviceread to work. If it was an issue with the first sector though then wouldn't I get an error with the formatting in both scenarios instead of just one?

restart boot loader

I had a similar problem until recently. I have a GSM GN that I've never fooled with, and suddenly one day it wouldn't charge when I plugged the micro usb port into it. I would have to plug in the micro usb side, then pull and replug the other end of the cable. It was bizarre. I tried other cables, chargers, etc. All the same.

However, I think I fixed my problem by entering the boot loader and restarting it. Power off, then hold power and both volume keys. When the boot loader appears, you can press volume up and down to select "Restart boot loader" and then hit the power key. After I did this, the GN started working normally again.

Hopefully that'll help you fix your problem.
