[R&D] Port SDCard Recovery to Other Exynos4412 Devices

AdamOutler · Nov 12, 2012

This thread's purpose is to port the Boot from SD recovery from Galaxy S3 to other devices. Since there is no procedure, and I am performing the work, the final output will be named UnBrickable SD to follow along with my previous work with UnBrickable Mod.

Goals:

Obtain IROM Dump [100%]
The IROM contains information about the internal workings of the processor. We now have an Exynos 4412 IROM and IRAM dump which contains all information about booting procedures. Thanks to mdrjr for using his 4412 development board in UBOOT mode to pull the dumps.
Analyze IROM for boot-from-ExternalSD bit [100%]- In Progress
We've sucesfully booted from SDCard and run unsecure code.
Define General structures which may help to identify future boot-from-ExternalSD temp-mod [30%]
Once the memory location of the boot-from-ExternalSD pin is known, testing can occur and generalizations can be made.
Make an overlay template of the Exynos4412 processor [0%]
This overlay will make finding the pin on future Exynos4 devices easier. Requires removal of a processor from an Exynos device.
Find a way to make an UnBrickable Mod [10%]
This goal may be removed pending IROM analysis. We've booted from SDCard and run unsecure code.
Port to other devices
They will be listed here and this thread may be moved to Hardware Hacking eventually.

Initial information
Here's what I've been able to pull up about the device so far.

How to recover an i9300 from bootloader failure
This can be used as a model for what is trying to be accomplished here. This will be reproduced, the goal is to identify the proper resistor on each device which is mentioned in the PDF below.

We may be looking for an XOM resistor
I believe the resistor triggers an XOM[] resistor (as Samsung calls them) or Boot Mode resisor. XOM resistors are responsible for switching on or off a register inside the processor which is cheked by IROM on each boot. When the array of XOM registers match a value, the processor is commanded to boot from a predetermined source such as OneNAND, EMMC, or USB. The XOM5 resistor on the Hummingbird (AKA Exynos3xxx) processor was responsible for boot-from-USB mode and enabled UnBrickable Mod to take shape with the elite assembly hacking from Rebellos.

This image shows the XOM[0] value. Unlike the Exynos3, XOM[0] does not control boot sequence. Until I saw this picture, I had hypothesized based upon my work with Exynos 42xx processors that the XOM[0] and XOM[6] registers control clocks. This image confirms it.

So, this narrows it down somewhat, but not much. Based on my previous work, we are likely looking for XOM[1...5],

The Memory
Here is an example from the Exynos42xx IROM which was decompiled into assembly, then converted into C and annotated properly by Ralekdev. http://pastie.org/private/p9x0yhcmegxjrxtkn6nxoq . The Exynos 42xx processor is very much different from the Exynos 3xxx processor. And to throw another monkey wrench into the gears, the Exynos 44xx processor is different from the 42xx processor in regards of this thread.

Here is the memory map pulled from the Exynos4412 processor. This shows the IROM location in which we are interested.

The Resistor
I can infer from the documentation that the resistor which is shorted is part of a voltage divider. The divider's operation causes the voltage to be either low or high normally and the shorting action causes the divider to swing the other direction. This divider may or may not be present on other Exynos devices as the feature is not documented, we cannot rely on this structure being there. The resistor will be there for sure, but it may not be as simple as shorting two contacts.

Current Tasks

Galaxy S2 (all variants except Skyrocket)
Galaxy Note 1 and 2 (non-qualcomm variants)

I found this picture of the Exynos 4412 taken from a SGS3, with resistors. It gets cut out a bit on the top, but that's the best I managed to find.

This one is from a development board; at first glance the resistors look different compared to the one above, but I'll link to it anyway:

And these two are for the motherboard:

Not sure if you've noticed. But dumps are empty

Why? It's protected memory area using ARM TrustZone and it's unreadable from kernel level. Someone with JTAG access could dump it before SBL gets executed. Or maybe there's some engineering version of bootloaders that doesn't block iROM in TZ.

Once again, Samsung decided to screw us.

Hopefully droid 4412 has less security than gs3. http://odroid.foros-phpbb.com/t1671-irom-dump

as I said to adam on odroid forums.

I'll get in touch with him to help with that.

I have a Meizu MX HK version(now my wife's phone) in front of me. I tried running viewmem on it..

Code:

shell@android:/data/local/tmp # ./viewmem 0x02020000 0x10000                   
[INFO] Reading 65536 bytes at 0x2020000...
[2] + Stopped (signal)     ./viewmem 0x02020000 0x10000 
[1] - Bus error            ./viewmem 0x02000000 0x10000 
shell@android:/data/local/tmp #

so then I tried from a UART prompt.

Code:

root@android:/data/local/tmp # ./viewmem 0x02020000 0x10000 
[INFO] Reading 65{0}[  100.815755] Unhandled fault: external abort on non-linefetch (0x018) at 0x400fc000

{0}[  101.417026] Unhandled fault: external abort on non-linefetch (0x018) at 0x400fc000
root@android:/data/local/tmp #

Rebellos, can you tell anything by these kernel messages? external abort on non-linefetch? These are kinda cryptic but I guess it's saying the input was aborted?

Anyway.. I then tried to analyze the bootloader messages...

Code:

OK

I had to edit out parts of the above log. This UART device is /dev/ttySAC3, which i found interesting because on Samsung they are usually /dev/ttySAC2

This is a U-Boot device.. Amongst the messages I see press ... but ctrl+c does nothing at all. I can't get into the UART prompt. I suppose that inserting a custom U-Boot would render the TrustZone inoperative and then crash the device.. I don' t really know.. I don't have a way to recover yet either. So, any suggestions are appreciated.

I have a binary. Over at the Odroid forum, someone was able to pull a dump from U-Boot under minicom. So i had a HexDump format. I wrote the following Java file to convert the hex dump to a binary

ConvertHexToBinary.java:

The following are messages from inside the converted-from-UART-UBOOT-hex-to-binary file

Code:

SB20_CONTEXT
SB10
[UART BOOT] Fail, Can not receive data ack
[UART BOOT] Fail, Can not connect to DNW
[UART BOOT] Load boot binary and then press any key to download

Looks like we got what we need. Rebellos, Ralekdev, can you verify this?

Attatched is the original hexdump and the recombined binary using the above program for the first time. Also, i've attatched files by memory locations 0x02000000(IROM) and 0x02020000(IRAM).

Rebellos · Nov 16, 2012

@External abort on non-linefetch - this is for sure abort generated by ARM TZ subsystem when there's memory access request from non-secure to secure area.

@Dump -I can confirm this is full iROM dump. Just not sure if iRAM (containing iROM bss section and EBL+IBL) isn't somehow corrupted.

I was hacking around in the memory on my Galaxy Camera(basically the same as an S3). By trial and error I found the lowest readable section of memory was 0x40000000. At that location I found this message:

Code:

ATconsole=ram loglevel=4 sec_debug.level=0 sec_watchdog.sec_pet=5 androidboot.debug_level=0x4f4c sec_log=0x200000@0x46000000 s3cfb.bootloaderfb=0x5ec00000 sysscope=0xee000000 lcdtype=0 consoleblank=0 lpcharge=0 lpj=3981312 vmalloc=144m oops=panic pmic_info=67 cordon=b4c230bbb3d4a1ecc04492a6e7fb7512 androidboot.emmc_checksum=3 androidboot.odin_download=80300280 androidboot.bootloader=GC100XXALJF androidboot.serialno=4208fcaa2cd59fc5 snd_soc_core.pmdown_time=1000

So i decided to check out the sec_log at 0x46000000. It appears to be a rolling log. It continually updates and contains several copies of the same information.

Here's a memory log of Bootloader+first bit of kernel. I'm used to seeing this information in UART. It's written to memory on this device:

Just a question Adam...

Afaik on the S3 the param partition isn't J4FS, if i remember right is ext4 or similars...
Do you think SBoot can read j4fs too (for the params)?

Or maybe we could mod an S3 param.bin to make it as needed.

BTW i can be a tester in the weekend

Well, the Galaxy Camera PARAM is not mountable as EXT4. Is it mountable on the i9300? Can you pull a log dump and get me a copy of the PARAMS partition? PARAM is generaly a single file which contains setting+splash images.

use the Basic Hacking Tools Installer to get the ViewMem utility http://xdaforums.com/showthread.php?t=1424811. Commands to get a log dump:

Code:

viewmem 0x46000000 0x00200000>/sdcard/log.txt

Then upload the log.txt somewhere.

Ok, yeah, that's not a filesystem. It's a Params.lfs file. Same as always. It is binary settings+binary representations of images created with "JFIF Lead Technologies". I'm sure they have a method of combining those files into a PARAM partition, and there IS a way of extracting the images. But it's not a filesystem.

As for the log, Samsung must have changed the location. That looks like app-data. Delete that file so as not to spread your app data info.

Please run this check the memory location:

Code:

viewmem 0x40000000 0x1000

Which will produce a 4096byte log on-screen. Then look for a line like this...

Code:

ATconsole=ram loglevel=4 sec_debug.level=0 sec_watchdog.sec_pet=5 androidboot.debug_level=0x4f4c sec_log=0x200000@0x46000000.....

Get the "sec_log" variable information and run viewmem with those two numbers reversed.

You're basically looking at the unsecure memory header information which gives you the address to the secure_log which is what I'm looking for. The secure log will have SBOOT information in it.

Tar opens it up, but there are also command line SBOOT parameters in there. if you view as a hex file you'll see: "'console=ram loglevel=4" . So, i'm guessing it must be a bit more complex than simply a tar file. As I understand it, a TAR file is a header with information cat'ed in after it. I think the decoded tar format is dropping the actual param information though...

edit: unless adv-env.img contains those settings? I'm away from my computer so I can't tell for sure. That console=ram needs to be changed to /dev/ttySAC2

AdamOutler · Nov 22, 2012

I'm collecting information from Ralekdev and Rebellos. They've been researching a lot and I'm going to let them post their findings. However, I want to say that UnBrickable mod looks possible on the Exynos4x12 devices. Also, SDCard boot has been confirmed.

Anyway, I have been looking at the hardware around the processor of the Galaxy Camera. Here, have a look:

I believe the enlarged resistors to be the XOM pins. I don't have enough documentation or hacking yet to determine what each one does, nor their numerical order. I will be experimenting with them tonight though. I've marked out the facts about the board in Green and Purple.

The green lines are the visible grounding points. These resistors are low values.

The unmarked resistors are those which are either high or carry clock signals.

The purple dots are almost positively the XOM pins. I hope to somehow identify the purple as XOM0, XOM1.... XOM7. I don't have any clear ideas about how to identify the pins except by trail and error, but I will try. The purple dots are the points which need to be modified for testing. One of them needs to be brought low or high to reverse the boot order.

The blue areas are potential UART points. We have two UARTs to locate. these UARTs are identified in the manual as UART2 and UART3. In Linux they become /dev/ttySAC2 and /dev/ttySAC3. These devices are not created by default, but you can create them on your own system with root permissions.

Code:

su
mknod /dev/ttySAC0 c 204 64
mknod /dev/ttySAC1 c 204 65
mknod /dev/ttySAC2 c 204 66
mknod /dev/ttySAC3 c 204 67
mknod /dev/ttySAC4 c 204 68

These commands create the /dev/ttySAC which can be accessed by busybox microcom.

So, work is nearly complete on GOAL #3 of this thread. Goal #4 and and UnBrickable Mod are still dependent upon IROM analysis.

I am able to send information through the USB port and read the information coming from the /dev/ttySAC2 device. This means there IS a hardware link, but the information is getting garbled. It's possible that it could be a different speed than I am used to.

Now, another thing. When I start the device and watch the USB port for data I'm seeing this:

It's a repeating patern of " ef bf bd " which makes me wonder if this is some sort of signal for input of some kind.

When using a 150Kohm resistor between USB pins 4-5, the device takes about 10 seconds to boot up. This would signify that the processor is doing something. The 150Kohm resistor has traditionally be the "UART" communications resistor for the GS series... Maybe it is expecting a firmware upload. However, I am not receiving any messages about that.

In order to continue the boot-from-sd, I need someone to create a "T-Flash" image on a GS3 then make a dd image of the sdcard so I can flash it to my own. Odin is failing to flash the GCam with GS3 SBOOT. I need some help on this.

I made a tiny dd (16 MiB) from the beginning of my t-flashed sdcard. I think this should be enough.

if you need a fulldump though give me some time. I only have 8 GiB sdcards. But I think this should be ok. Basically, the t-flash just writes a 512 Byte header to the sdcard and then after that the sboot.bin content follows.
