mission impossible - editing nk.exe

cross posting from universal upgrading ... can someone kill the other thread ?
can someone assist me in changing the nk.exe in a way that allows me to change the deviceid from PU10 to HERM100
i succeded in hexediting the hk.nba from PU10 to HERM with the confirmation that Getdevice data recognize it as HERM
http://wiki.xda-developers.com/index...=GetDeviceData
there are 2 places in the nk.nba where the device type is found
00007074h: 48 00 45 00 52 00 4D ; H.E.R.M
00316c74h: 48 00 45 00 52 00 4D ; H.E.R.M
i need to get H.E.R.M.1.0.0 instead (6 bytes to insert)
00007050h: 2C 00 25 00 64 00 2C 00 20 00 4E 00 61 00 6D 00 ; ,.%.d.,. .N.a.m.
00007060h: 65 00 20 00 69 00 73 00 20 00 25 00 73 00 0D 00 ; e. .i.s. .%.s...
00007070h: 0A 00 00 00 48 00 45 00 52 00 4D 00 00 00 00 00 ; ....H.E.R.M.....
00007080h: 4F 45 4D 47 65 74 43 50 4C 44 5F 47 50 49 4F 28 ; OEMGetCPLD_GPIO(
after dumping the rom including the boot XIP i found that the nk.exe contains this data.
the reason to do it is to "help" bbconnect to recognize it as a hermes
anyone can assist me ?

Hi,
Just a thought - wouldn't it be easier to patch BB Connect to recognise the PU10. I would have thought it tricky to "insert" any bytes, and for nk.exe to work, but to shorten a string in a file might work by either terminating the shorter string with a 00 null byte, leaving it's full length intact, or if it's got a preceeding length attribute, then simply amend that to the shorter value, i.e. from 7 to 4?
Cheers,
Steve.

[Q] Kernel Parameters found in Bootloader, can be modified?

Hi, well I've found the Kernel parameters in the bootloader posted here (Android 2.1 - 2.51 bootonly DOWNLOAD).
The parameters on the SBF are:
Code:
console=ttyS2,115200n8 rw [email protected] init=/init ip=off motobldlabel=none mtdparts=omap2-nand.0:128k(mbr),128k(mbmloader),256k(unused0),512k(mbm),512k(mbmbackup),512k(ebr),512k(bploader),512k(cdt),4m(pds),512k(lbl),512k(lbl_backup),1m(logo),2m(sp),512k(devtree),512k(devtree_backup),4m(bpsw),8m(boot),8m(recovery),13952k(cdrom),384k(unused1),512k(misc),512k(cid),4m(kpanic),334464k(system),384k(unused2),512k(prek),512k(pkbackup),200m(cache),455296k(userdata)
And the parameters in my current stock rom:
Code:
console=ttyS2,115200n8 console=ttyMTD10 rw [email protected] init=/init ip=off brdrev=P3A androidboot.bootloader=0x0000 mtdparts= mmcparts=mmcblk1:p7(pds),p16(recovery),p17(cdrom),p18(misc),p19(cid),p20(kpanic),p21(system),p22(prek),p23(pkbackup),p24(cache),p25(userdata) androidboot.mode=normal
Well, that comes from a sbf file, so, I guess if i modify it, the stuff about the original bootloader wont work, ant I guess the mobile wont startup.
Am I right in that?
Im asking because if I pass another parameter (about the Framebuffer OMAP2, the screen driver), I can use X11 native, and that will be great!

the one in 3.4.2-164 :
Code:
Kernel command line: console=/dev/null rw [email protected] init=/init ip=off brdrev=P3A androidboot.bootloader=0x0000 mmcparts=mmcblk1:p7(pds),p15(boot),p16(recovery),p17(cdrom),p18(misc),p19(cid),p20(kpanic),p21(system),p22(prek),p23(pkbackup),p24(cache),p25(userdata) androidboot.mode=reboot
got in dmesg or cat /proc/cmdline as root

how do you modify the boot parameter?

i found in cdt partition (hexdump), this partition table description, confirmed and completed with sbf_flash tool :

marked ??? are partitions formats to be determined...
xCG : never seen in full sbfs
descriptions :
lbl : Linux Boot Loader (sources in motorola sdks) contains Motorola Cert. 4496 4498
system : /system folder
userdata /data folder
cache /cache folder
cdrom : cdrom iso with defy drivers (by usb ?)
pds : /pds folder ... hmm dunno exactly what it is, used by ClockWorkMod Recovery
recovery : when you boot with bottom volume button
bpsw : something compressed ??? + Motorola Cert. 4504 4506
sp : like cdt, but 3x Motorola Cert. 4496 4498 (maybe old end of file)
prek : Pre Kernel Interface, which switch to recovery mode, Motorola Cert. 4496 4498
devtree : look like /dev content, Motorola Cert. 4496 4498
devtree_backup, misc, cid, kpanic : empty
mbmloader: checks signature of mbm
mbm: verifies all other signatures before allowing the device to boot.
mbr, ebr : master boot record, extended boot record
cdt: Codegroup Descriptor Table (partition table + the kernel command line + Motorola Cert. 4496 4498)
sp seems to be a copy of cdt

Its hardcoded in kernel config and/or set/completed by bootloader...
But maybe there is a way to set additionnal parameters somewhere... like the "androidboot.mode=reboot" parameter

Edit the SBF bootloader in binary mode. Those parameters are not compressed. You can delete a character and add another to get the same space of the string. But the thing is, in my Bootloader, I have 498M of ram, instead, in the one that I ve seen, there is 488M. And, there are some differences, in my boot, I have the partitions in mmcblk instead in mtdblk. I guess i can brick my phone if I change those.

If you do so you'l probably destroy the hash of the bootloader and your device won't boot any more. This is the biggest problem of the signed bootloader from motorola

Yep, I was thinking in that in my first post. So I just will keep the information, its usefull to know the partitions and the memory configuration.

[Q] CWM can't mount partitions

Hi,
I have a problem with an Asus TF700T. I had Clockworkmod Recovery installed and tried using it to flash Cyanogenmod. The flash failed and since then, CWM can't mount /data, /system or any other partition from the internal flash memory. I've then used fastboot to flash a new version of CWM, but also the new version (6.0.4.7) can't mount the partitions.
I fear the partition table of /dev/block/mmcblk0 may have been damaged, but recovery works fine. I have access to CWM, adb and fastboot.
Is there a way to fix the partition table or some other way of making the partitions mountable?
I used adb shell for some diagnostics:
cat /proc/partitions
major minor #blocks name
179 0 62087168 mmcblk0
179 32 4096 mmcblk0boot1
179 16 4096 mmcblk0boot0
179 48 15558144 mmcblk1
179 49 15554048 mmcblk1p1
After a reboot (with a half installed Cyanogenmod) somehow, the output is:~ # cat /proc/partitions, but CWM still can't mount /data, /system, etc...

That looks quite correct. What happens when you try to mount /data manually?
mount -t ext4 /dev/block/mmcblk0p8 /data

Thanks, good idea. But unfortunately, the error message isn't very detailed:
Code:
mount -t ext4 /dev/block/mmcblk0p8 /data
mount: mounting /dev/block/mmcblk0p8 on /data failed: Invalid argument
I also tried to check the filesystem with e2fsck:
Code:
~ # e2fsck /dev/block/mmcblk0p8
e2fsck 1.41.14 (22-Dec-2010)
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/block/mmcblk0p8
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

Is there any message in dmesg after trying this?
What do you get from "hexdump -C -n 2048 /dev/block/mmcblk0p8"?

No, no messages in dmesg after the mount command, only updates like this:
Code:
<4>[ 81.890682] cpu ext_temperature=26
The output from the hexdump command:
Code:
~ # hexdump -C -n 2048 /dev/block/mmcblk0p8

Funny. Normally the superblock should start at offset 0x400. Yours appears to have gotten wiped.
Try the same command on mmcblk0p1, mmcblk0p2, mmcblk0p3, mmcblk0p5 and post the results just to find out what's going on.

Thanks already for your help, to be honest I have no clue what I'm looking at. Are those the first 2048 bits of each partition?

Yes. All other partitions except /data look normal - p1 is /system, p2 is /cache, p3 is the bootloader command partition which is usually empty, p5 contains device configuration in a FAT32 filesystem.
Try formatting /data from the recovery, then reinstall your ROM (which will format and fill /system).

Ok, do you mean the format command I can select in recovery? Because it says:
Code:
Formatting /data...
Error mounting /data!
Skipping format...
Done.
But can I maybe use mke2fs or something similar to format /dev/mmcblk0p8? If so, could you tell me what options I should use?
Thanks

I have no experience with CWM; apparently it sucks.

Code:
make_ext4fs /dev/block/mmcblk0p8
should do it. Assuming that CWM ships with a make_ext4fs binary.

Thanks, that worked! CWM does ship with make_ext4fs, I flashed Cyanogenmod and it booted successfully! :victory:

I figured I would post my experience with a sudden bootloop. My tf700t was unlocked and rooted a very long time ago and I've used a few ROM's since doing that. First was CROMI-x then Cyanogenmod 11 nightlies then CROMBi-kk and then I switched to ZOMBI-x.
I installed Zombi-x using F2FS file system and never had any issues except for the usual mind numbing lag from the horrible IO issues.
So just last night (12/21/2014) my tablet froze with a light grey screen and about 10 seconds later it rebooted, but it kept rebooting over and over. I tried cold booting, but that didn't help, so I booted into CWM (ver. 6.0.4.7) and tried to do a wipe data/system reset, but the tablet would just reboot part way through. I tried formatting the /data partition directly but it caused the tablet to reboot as well. So a few other posts around the interwebs led me to the conclusion that I needed to get rid of clockworkmod and switch to TWRP.
Thankfully I was able to connect to the tablet using fastboot, but only in Linux. (my Win7 PC saw that something was there, but it wouldn't let me install the driver)(http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378) So I installed TWRP 2.8.3.0 and used it to do a complete wipe. It started the format but had several errors about not being able to mount /data and then it said it was formatting Data using ext4fs. I've read that it should only take 5 minutes or so, so you can imagine my worry when 5 minutes past and then 10 and so on until it finished up after a little over 30 minutes, so if it's just sitting there, there's a good chance it is actually doing something, so leave it be for awhile and don't forget to check your battery, you don't want your tab to shut off suddenly!
I reinstalled CROMBi-kk and let it boot. Much to my surprise it booted and the resulting performance was nothing short of shocking!
So far this thing is running like it NEVER has before! The lag so far is so much less than ever and things open and close very quickly!
So without any surprise here, I won't be using F2FS anymore for fear I'll have corruption on the internal storage again! Thankfully TWRP came through for me. So if your tf700 is bootlooping and you still have fastboot, try installing the latest TWRP, it may just make the difference between a functioning tablet and a brick!

The long time it takes for formatting and the performance gains are actually related. Creating the filesystem takes probably less than 5 minutes, but then the recovery does a "trim" on the free blocks - telling the eMMC that it may discard the data in these blocks and erase them. Erasing flash memory is slow. But following write requests by the booted ROM will be much faster because they can be written directly without prior erasing and shuffling data around.

So the performance boost after formatting /data is temporary until the emmc again has to shuffle data around when it gets write requests?
I thought f2fs was supposed to take care of that?

Using f2fs should increase the time until the eMMC has to shuffle data around because it does less random writes. But when all blocks have been written once, something must be erased to rewrite more. The permanent solution is to run fstrim regularly (I've seen some comments in the Android source code that runs it automatically from time to time) or to mount with the discard option, and to leave a reasonable amount of space free (10 to 15%).

It doesn't seem that lagfix can trim /data formated to f2fs.

Tutorial for Re-partitioning storage of MTK6589/MTK65xx + Flash through CWM/TWRP

Tutorial/Guide for Re-partitioning MTK6589/MTK65xx + Increase your System & Data Partitions + Flash through CWM/TWRP + no need to use SPFlashTool
Part 1 :- To Flash existing modified EBR files through CWM/TWRP
There are plenty of guides for re-partitioning mtk devices, so why this one?
Well almost all of them suggest to use SPFlashTool to flash the "EBR" Files.
But we can do that by using CWM/TWRP (Custom Recoveries) as well!!!!!
no need to use SPFlashTool!
no need to format the Internal SDCard through PC!!
Just take your modified "EBR" files and put them into a Flashable Zip.
Edit the "updater-script" file to include the following lines.
Code:
[FONT="Comic Sans MS"][SIZE="3"][COLOR="Red"]package_extract_file("EBR1", "/dev/ebr1");
#put the name of your EBR1 file in place of "EBR1"
package_extract_file("EBR2", "/dev/ebr2");
#put the name of your EBR2 file in place of "EBR2"[/COLOR][/SIZE][/FONT]
Note :- If your device uses both the files then add both the lines and If your device uses only "EBR1" then add only the line of "EBR1".
Now add the following lines to format your "/system" , "/cache" and "/data" partitions.
Code:
[FONT="Comic Sans MS"][SIZE="3"][COLOR="Red"]
format("ext4", "EMMC", "/[email protected]", "0", "/system");
format("ext4", "EMMC", "/[email protected]", "0", "/cache");
format("ext4", "EMMC", "/[email protected]", "0", "/data");
[/COLOR][/SIZE][/FONT]
Note :- If you are going to increase your "/system" partition then you'll have to format the 3 partitions,
and if you just want to increase the "/data" partition then just include the lines for formatting "/cache" and "/data".
now save the "updater-script" file and replace it in the Flashable zip!!
Or , you can use this sample flashable zip file.
download it and put your EBR files in it!!!!
edit the "updater-script" file according to your need and replace it in the Flashable zip!!
copy the Flashable zip file to your external SDCard
reboot to recovery
select install from zip file and choose the flashable zip file
Flash it.
Remember after flashing the EBR files do not restore your previous CWM/TWRP Backup.
Just Flash any CWM/TWRP Flashable ROM available for your device!!
Wipe Dalvik Cache if you haven't done it already!!
reboot and see for yourself!!!
Disclaimer :-
I will not be in anyway responsible for any damage this might cause to your phone.
if you'll follow the instructions correctly, then everything will be fine.

Part 2 :-
for understanding your MTK device's partitions, first read this excellent guide posted by @tirta.agung --> [Noob Guide] Understanding the Hex value of MTK's MBR/EBR1/EBR2
So How to Increase the system partition? or the data partition?
I'll tell you!!
I use MMX Canvas HD A116 (mt6589)
it has 4GB internal storage distributed as below:
/system = 650mb
/cache = 126mb
/data = 1gb
Internal SDcard = 1.77gb
i wanted to change it to this:- (and i've done it!!!)
/system = 900mb
/cache = 126mb
/data = 2gb
Internal SDCard = remaining space i.e around 536mb
Note :- First please read the above mentioned guide, otherwise you won't understand this!!
let me try to make it simple to you
this is the hex format of "EBR1" & "EBR2"
EBR1 of MMX A116 (mt6589) :-
00 00 00 00 83 00 00 00 00 08 02 00 00 50 14 00 --> Partition 5 /system 650MB
00 00 00 00 83 00 00 00 00 58 16 00 00 f0 03 00 --> Partition 6 /cache 126MB
00 00 00 00 83 00 00 00 00 48 1a 00 00 00 20 00 --> Partition 7 /data 1GB
00 00 00 00 05 00 00 00 00 b4 01 00 ff ff ff ff --> points to ebr2
EBR2 of MMX A116 (mt6589) :-
00 00 00 00 83 00 00 00 00 94 38 00 ff b7 c5 ff --> partition 8 Internal SDCard
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Note :-
numbers in red --> Offset of partition
numbers in DarkOrange --> Size of Partition

Now if you notice carefully these partitions are continuous/contiguous.
133120 + 1331200 = 1464320
1464320 + 258048 = 1722368
i.e no.of sectors before partition + the length of the partition = no.of sectors before the next partition
// 133120 = no.of sectors before "/system" partition i.e "/system" starts from sector no. 133121
// 1331200 = the length of "/system" i.e "/system" is of 1331200 sectors.
// 1464320 = no.of sectors before "/cache" partition i.e "/cache" starts from sector no. 1464321
// and so on
The last line in EBR1 points to EBR2.
(This one --> 00 00 00 00 05 00 00 00 00 b4 01 00 ff ff ff ff )
and the First line in EBR2 is the one for the partition of Internal SDCard.
(This one --> 00 00 00 00 83 00 00 00 00 94 38 00 ff b7 c5 ff )
Even after reading many guides, I haven't found a proper explanation of this anywhere.
in one of them it states that,
D = (A + B) - C
where,
A = no.of sectors before "/data"
B = size of "/data"
C = offset of EBR2
D = offset part in EBR2
E = MaxValue - (A + B)
where,
MaxValue = FFFFFFFF (Hex) = 4294967295 (in decimal)
A = no.of sectors before "/data"
B = size of "/data"
E = Size part in EBR2
A = 00 48 1a 00 --> 001a4800 --> 1722368 //offset of "/data"
B = 00 00 20 00 --> 00200000 --> 2097152 //size of "/data"
C = 00 b4 01 00 --> 0001b400 --> 111616 //offset of ebr2
Max Value = FF FF FF FF --> ffffffff --> 4294967295 //?
Note :-
in Red --> Hex values in little endian
in Orange --> Hex values in big endian
in Blue --> Decimal values

Click to collapse
D = (A+B) - C = (1722368 + 2097152) - 111616 = 3707904
E = MaxValue - (A+B) = 4294967295 - (1722368 + 2097152) = 4291147775
D = 3707904 = 00389400 = 00 94 38 00
E = 4291147775 = ffc5b7ff = ff b7 c5 ff
so now you've got a good idea of what the values in "EBR" files mean, haven't you!!
Now here comes the Important part i.e how to modify the partition sizes.
I wanted "/system" = 900mb , so
So we get "00 20 1C 00" as the value for 900mb
(note-down these new values as we'll need to use them later)
now as we've increased the size of system we need to change the offset of the next partition so that there won't be any overlapping/corruption of partitions.
and how do we do that --> "no.of sectors before partition + the length of the partition = no.of sectors before the next partition"
i.e 133120 + 1843200 = 1976320 //new offset of "/cache"
decimal value --> 1976320
Hex value in big endian --> 001E2800
Hex value in little endian --> 00 28 1E 00
So we get "00 28 1E 00" as the value for sectors before "/cache"
i don't want to change size of "/cache" so it remains same i.e "00 f0 03 00"
now we need to offset the "/data" partition
("no.of sectors before partition + the length of the partition = no.of sectors before the next partition")
1976320 + 258048 = 2234368 // the number of sectors before "/data" partition
decimal value --> 2234368
Hex value in big endian --> 00221800
Hex value in little endian --> 00 18 22 00
So we get "00 18 22 00" as the value for sectors before "/data"
now i want to make my "/data" to 2gb i.e 2048mb
So we get "00 00 40 00" as the value for 2048mb
The last line in EBR1 Points to EBR2 so don't make any changes to it!!!
So now our modified EBR1 Becomes like this:-
00 00 00 00 83 00 00 00 00 08 02 00 00 20 1c 00 --> Partition 5 /system 900MB
00 00 00 00 83 00 00 00 00 28 1E 00 00 f0 03 00 --> Partition 6 /cache 126MB
00 00 00 00 83 00 00 00 00 18 22 00 00 00 40 00 --> Partition 7 /data 2GB
00 00 00 00 05 00 00 00 00 b4 01 00 ff ff ff ff --> Link to ebr2
now we need to offset the Internal SDCard's partition which is in EBR2
calculate new D & E :-
D = (A+B) - C
where,
A = no.of sectors before "/data"
B = size of "/data"
C = offset of EBR2
E = MaxValue - (A+B)
where,
MaxValue = FFFFFFFF (Hex) = 4294967295 (Decimal)
A = no.of sectors before "/data"
B = size of "/data"
A = 00 18 22 00 --> 00221800 --> 2234368 //offset of "/data"
B = 00 00 40 00 --> 00400000 --> 4194304 //size of "/data"
C = 00 b4 01 00 --> 0001b400 --> 111616 //offset of ebr2
Max Value = FF FF FF FF --> ffffffff --> 4294967295 //?
D = (A+B) - C = (2234368 + 4194304) - 111616 = 6317056
E = MaxValue - (A+B) = 4294967295 - (2234368 + 4194304) = 4288538623
D = 6317056 = 00606400 = 00 64 60 00
E = 4288538623 = FF9DE7FF = ff e7 9d ff
That's it, now we've got all the values ,it's time to put them into the EBR Files.
So this is the result of our modification:-
Modified EBR1 :-
00 00 00 00 83 00 00 00 00 08 02 00 00 20 1c 00 --> Partition 5 /system 900MB
00 00 00 00 83 00 00 00 00 28 1E 00 00 f0 03 00 --> Partition 6 /cache 126MB
00 00 00 00 83 00 00 00 00 18 22 00 00 00 40 00 --> Partition 7 /data 2GB
00 00 00 00 05 00 00 00 00 b4 01 00 ff ff ff ff --> Link to ebr2
Modified EBR2 :-
00 00 00 00 83 00 00 00 00 64 60 00 ff e7 9d ff --> internal sdcard
To edit "EBR" files :-
Open your ERB1 & EBR2 files in hex editor and replace the respective values with our modified values.
save the files and put them into a flashable zip and flash through CWM/TWRP or whatever custom recovery that you use!!!!
Remember after flashing the EBR files do not restore your previous CWM/TWRP Backup.
Just Flash any CWM/TWRP Flashable ROM available for your device!!
Wipe Dalvik Cache if you haven't done it already!!
reboot and see for yourself!!!

sd meory card - unable to mount

Hello,
i just remove my sdcard from my android phone (lollipop), iput another sd card inside to format, i make the format,
then i put back the original sd card ( samsung 16G ), but the phone refuse to mount it, and use it as internal memory, except if i format it .
the point is that i canot mount my sdcard not my pc (linux debian 8), so to get my data. the reason is an I/O error, and fdisk, dd, refuse to work with the sdcard. My OS cant report any partitions in card, and any try to read is an IO Error.
here is a snaphost of hdparm :
