this sounds interesting but I'm not known to that technique yet.

we could perhaps use fakeflash, too.
[Acer Iconia A500] sc2k:
Bootloader seems to be encrypted

Seems like the BL is encrypted...

According to the partition table, BL should be placed @0x180000 on /dev/mmcblk0

But there seems to be encrypted stuff. I think the algorithm described in this patent is used:

faqs.org/patents/app/20100070743

--> Encrypted using SBK

According to [0027], the SBK may be flushed from the keylot in the encryption engine by the BL..

I hope acer just forgot to implement this ^^
[Acer Iconia A500] netham45:
Anyone know what kind of signature it is? 'Checksum' tells me it might be CRC, which would be just for integrity and easially spoofed.
[Acer Iconia A500] sc2k:
I think the checksum starts at +0x240 and seems to have 20 bytes. Any idea what this could be?

Edit: could be sha1

Edit2: It is SHA-1..
[Acer Iconia A500] daveba:
0x240 is the offset into the header of the id element used for writing the SHA1 signature as defined in the bootimage.h and written by the mkbootimage program in the sdk. Nothing new here. Look at the bootimage.h

#define BOOT_MAGIC "ANDROID!"
#define BOOT_MAGIC_SIZE 8
#define BOOT_NAME_SIZE 16
#define BOOT_ARGS_SIZE 512

struct boot_img_hdr
{
unsigned char magic[BOOT_MAGIC_SIZE];

unsigned kernel_size; /* size in bytes */
unsigned kernel_addr; /* physical load addr */

unsigned ramdisk_size; /* size in bytes */
unsigned ramdisk_addr; /* physical load addr */

unsigned second_size; /* size in bytes */
unsigned second_addr; /* physical load addr */

unsigned tags_addr; /* physical addr for kernel tags */
unsigned page_size; /* flash page size we assume */
unsigned unused[2]; /* future expansion: should be 0 */

unsigned char name[BOOT_NAME_SIZE]; /* asciiz product name */

unsigned char cmdline[BOOT_ARGS_SIZE];

unsigned id[8]; /* timestamp / checksum / sha1 / etc */
};
[Acer Iconia A500] sc2k:
The actual checksum must be somewhere else.. flashing a working boot.img from mmcblk0p2 to mmcblk0p1 will also result in the SOS message.

If the checksum is somewhere outside it must be written by recovery.. there is some interesting code where recovery writes 4x 16 Bytes to mmcblk0p7 @0x84 after installation succeeded. It's 4x the same pattern but in my dump other data is shown there.

Any ideas what this could be?

Btw: mmcblk0p5 also has some boot flags. E.g. you can enable a tty console by calling:

$ su

$ misc_command debug on

This will modify mmcblk0p5. After reboot console=... Is appended to your boot options .

Entering recovery mode will reset the debug flag.
[Acer Iconia A500] huxflux2003:
I believe that each partition has a different valid checksum. So something that passes the check for mmcblk0p2 does not pass for mmcblk0p1. There must be list of partitions and associated checksums somewhere.
[Acer Iconia A500] seraphimserapis:
This part seems to be interesting:

partition read matched size 3043328 sha 23917956b398554dc14fe6c2d86ab3e358bfba5c
Removing unneeded files...
[Acer Iconia A500] huxflux2003:
This is a very good hint!

Edit: not really. This is after the signature check...
[Acer Iconia A500] netham45:
yea, but if it's not checking that signature every boot and only checking the checksum, we could build the image and use dd to flash it
[Acer Iconia A500] huxflux2003:
But can't we already do that now? /system can be flashed with whatever you want.
[Acer Iconia A500] netham45:
But if the checksum on the boot.img isn't valid, it will refuse to boot.
[Acer Iconia A500] thor2002ro:
we can use recovery partition for testing...
[Acer Iconia A500] Crsdr37:
Correct me if I'm wrong. But even if we could DD a system.img. which we already can. If you make a custom system.img. you just screwed everybody when Acer releases an update. Because it verifies the system.img. at the point of the update.....
[Acer Iconia A500] netham45:
It's pretty much a given that a custom ROM would kill the updater.

Edit: Also, System.img isn't what we need unlocked, but the recovery.img and boot.img, so if we screw up the System.img we can reflash it.
[Acer Iconia A500] huxflux2003:
But if we screw the recovery partition, won't we be unable to use the chinese update.zip to recover to stock?
[Acer Iconia A500] thor2002ro:
yes if you screw the recovery up you cant use the update.zip but if the boot is ok you can boot into android and restore recovery

[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:

[EVO 4G Q&A, Help & Troubleshooting] dezel29:
anywhere from .50 mbs to 2 mbs...the same on 3G as 4G...if i run speedtest app i get 5-9mbs on 4G, but run the test on the pc that is tethering off of the phone and its anywhere .5 to 2mbs
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
For some reason that seems to happen to a few people.

There was a thread that was saying that you may have better speeds if you use a proxy on the pc with proxy on the tether.

Then I got my Diamond, and began flashing like crazy...even released my own ROM, which proved to be one of the most popular at the time..but then I bricked it, and got an HD2 (which I still use). I cooked for the HD2 for a while....then lost interest in WM when Android was ported to the HD2.

Then I applied to be a forum mod, which I was for some months, before becoming a senior mod.

Hello,

I have a MT4G, s-OFF, running eViL 4G-HD v.0.3.3 ROM with the Sense Kernel 1.0.

I am having very poor data connectivity issues. My 3G will only send out data (upstream) but no down stream. This will go on for 5-10 mins sometimes and then 4G will kick in and everything works fine for a few minutes. If the phone 'tries' to hard to gain connectivity it will freeze and reboot itself. Its becoming a pain in the ass... I have done alot of research on this and people on XDA say that a Sense ROM shouldn't have these issues, yet I am. Any solutions would be greatly appreciated!

At first its a tad slow but picks up speed and data will remain constant. This worked for me and may not work for others but give it a try, hopefully this will fix any data/cell signal loss!

[T-Mobile Sidekick 4G] dasmoover:

Would This Mean we could Convert from the default file system type (Rfs i think) to ext4 ? and does this mean the SK4G can have Voodoo lagfix which converts the system file type to ext4 i believe ?

[T-Mobile Sidekick 4G] dasmoover:
These are kernel modules, they provide added functionality after boot to the stock kernel without having to recompile on the end-user level. Tun.ko lets you connect your phone to a OpenVPN network. Ext3 and Ext4 are file-system types. This would allow you to mount partitions/images with that file-system. I'm not sure if it would be applicable to /system, which is VFAT.

[T-Mobile Sidekick 4G] dasmoover:
Don't create any folder, place all the .ko files in that directory you took a screenshot of then do insmod tun.ko as root. You must first mount your /system partition as rw.
