Bootloader Unlocking - Galaxy 3 Android Development

So I've been looking at the Sbl.bin file with a hex editor..
It looks like it has a lot of things compiled into it... Things like: "Write SD Card Image to NAND", "Write Bootloader Image to NAND", "Autoboot in progress, press any key to stop".
There has to be a way to tap into this somehow.
Has anyone else tried hooking up to the 10 contacts on the back of their phone under the battery? (mine's covered with a sticker) It looks like it could be a RS-232 connection (Serial). It would be awesome to be able to tap into the bootloader and see what it can do.
... Just trying to plant the seed out there
.....
The Spica appears to have a similar connection:

I think the contacts is a jtag interface...

There's a 5 pin contact all in row. Then there are also 2 more 5 pins in a row so it makes a clump of 10.
Not sure what they are for sure.. I'm assuming JTAG and UART.. who knows.

like is jtag

How do you hard reset

Hey guys, How to do your hard reset TC, so i can get back to how i got it when i bought it.. Thank you.
Have you lost the owners manual? It should tell you in that
More helpful...
This is how I hard reset my xda orbit 2 (polaris):
1) Get your stylus and place it in the hole next to the USB port, BUT DONT PUSH! Just get it ready but dont actually push the button inside the hole.
2)Place your fingers on the Windows and OK buttons
3)Press and hold the buttons, dont let go.
4)Stright away push the stylus into the hole and press the button inside. You can let go of the stylus once the button inside has been pushed
5)Keep holding onto the Windows and OK buttons
6)After 5 seconds let go of the Windows and OK buttons
7)If asked to press SEND, just press the green pickup call button.
Thats all!
Hi. First of all, sorry for my english. Second - is this necessary to pull out the SIM card and the memory card, when doing a hard reset ? And how to make (or with which software) a backup of my data before reseting - sms,mms, some pictures, docs ?
10x in advance
Great... now the included CDs are lost too... What are you people doing? Seriously!
User manual pages 230-231 for the Hard Reset
For backup, pages 144-146, and software included on the CD...
It's in the manual (you know... little black book which has "manual" printed on it) for Christ's sake...
10x, but...in the user manuals is nothing written about SIM card. The only action required for a memory card is to be pulled out, if is encrypted. What about if is not encrypted ? There`s not a word...
Included CD do not start, because of "...requires Adobe Flash Player version 8.0 or latter...", although I have version 9.0...till now - I fixed it just now . And installed Sprite Backup. So...the only question is about the SIM card ? Sorry for a stupid question, if the answer is simple, but no one said nothing about SIM card. It`s hard to say goodbay for 220 phone numbers....
I did a hard reset with my XDA ORBIT 2 about 30 minutes ago.. I left the SIM card and memory card in. No problems here, all works fine.
Concerning encryption on the memory card, you either need to (before you hard reset) backup all the files from your memory card to something else (e.g. a computer) or turn off encryption.
If you turn on encryption then the memory card will only be readable on the PDA you turned the encryption on to. If you hard reset that PDA then your PDA 'forgets' that memory card's encryption technique and the files will appear corrupt.
So basically as long as you use your memory card on the pda you turned encryption on ONLY and you don't hard reset the PDA, then its fine.
If you need to change the PDA or hard reset it, you will need to backup/turn off encryption on your memory card before doing so.
Don't worry about the SIM card's data... but if you want to be 100% sure, take it out before the HR...

BTW just for the record, XDA ORBIT 2's don't come with a hardcopy manual; instead it is saved on the CD that comes with it.
If you lose the CD, it can be accquired from the O2 website -

If you try to backup all your contacts to the SIM before the hard reset, I would take extra precaution; some SIM cards vary in size and if you try copying your contacts to it sometimes they do not all get saved. This happened to me and I only got about 11 contacts on my SIM. I recommed the program PIM Backup be used before the hard reset. If anyone likes I can provide a link to download it.

OP said TC, not Oribt 2... and yes, I know about it.

This is exactly the reason why I don't bother saving contacts to the SIM. All my contacts are synced whith several PCs.
Everything is fine, guys. Now must do some tweaks and registry optimization.
10x a lot for your help.
np.. but on a final note could I recommend SKtools - it has a section on optimising ur device.
also if you turn off the large start menu bar you will find the device is a lot faster - credit goes to te person that posted that

verizon galaxy siii programming mdn required on non-stock roms?

Relocated from email discussion:
Hey, great tool[editorial: I think in reference to: http://code.google.com/p/cdmaworkshoptool/ ]. Would it be possible for me to get a copy of the most recent build? I'm looking into some things on the galaxy s3 because we lose the min and phone number on non-stock roms. -C
to C:
Most recent build is .2 which is public.. What exactly do you mean by lose? As in they must be reprogrammed after.a rom is flashed? Does the, normal version of dev term you have downloaded fail to write the number back?
3:39 PM (2 hours ago)
to me
It's a temporary problem with cm10. Development has been slow. It's lost on the first reboot and then mms doesn't work. In android, under status about it lists "My Phone Number" as unknown and Min as unknown. Just trying to see if I can write them while the OS is booted.
to C:
To write a mdn and min typically you would connect to the phone in diagnostic mode.. Send mode offline. Send spc. Then simply write mdn and min from the nam part of the interface.. There are typically three nv items which dev term writes for mdn, and min. Then, mode reset will reset and you can confirm if this wrote the nv item..
Did that answer any questions?
to C:
Having never tested a galaxy s iii I'm not sure if devterm should work... There is alot of chatter online about a program called ets, you might look.for that if devterm doesn't work. Please let me know if you are able to successfully write on the galaxy siii.
to me
We are able to write to it with qpst. I actually got the numbers back, but I'm not sure how. Now Im in the process of seeing if I can figure out how to replicate it. What is supposed to happen when you put it into reset mode? It doesn't work for me after that.
to C:
After mode reset the radio of the phone will literally reset.. Some phones this will actually turn off and on the whole phone.. Some will just show no.service temporarily... After mode reset.cdmadevterm will disconnect.from phone.. There are alot of variables, but typically if.qpst could write the phone devterm should also be able.. The mdn and min are really quite simply three nv items, I suspect the subsystem that normally stores this information is being overwritten or formatted by cyanogen...
if you have ever used cdma worksop or qxdm the mode offline and mode reset is functionally the.same..
to me
Thank you so much for going back and forth with me on this. I really appreciate it. The only major difference I noticed between an nv dump on stock and cm is that cm has a lock code for some reason. What is this ETS software you're referring to? CDMA workshop is a bit too expensive unfortunately.
Although I am not totally familiar with the tool it is linked on XDA in another section:
http://forum.xda-developers.com/showthread.php?t=1696621
I wonder if this might have something to do with the chipset not being qualcomm? On the other hand if you said it worked with qpst maybe they are somehow compatible?
The VIA tool probably won't work since we do have a qualcomm chipset. I still have not figured out how i managed to get it to work once but it came up with the unlock sim message I put in the code for my phone that I Found in nvram and then I tried the spc and a few other things and eventually hit dismiss. It said that it could not connect or something to that effect. Then I checked and it had my phone number as 000-000-xxxx which xxx was that unlock code. Then I restarted and I had the number again. I'm wondering if I somehow got the phone to let go of how its storing the phone number.
Hm. If it is qualcomm I would think that cdmaDevTerm should work... this is how one would normally write the mdn and min with devterm:
http://www.chromableedstudios.com/techninjutsu/howtowritemdnminwithcdmadevterm
Perhaps if this doesn't work you could include the response to the NV write from the LogQ tab to help understand the behavior? Maybe the rom is activating a different Nam profile or something?(I'm not sure if I even have a spot on the UI for that in devterm but a log might help understand)
(for logging purposes you may want to trying writing a fake phone number for privacy)
I guess my question also is: are you trying to figure out why the rom does this? or just a good way to fix it when it does?

usb problem

hello
i have a galaxy s6 root and run xsterolite rom. when i plug my phone to my windows 10 pc or macbook nether one of them recognize my galaxy. it say charging but nothing else. i update the driver and so on but nothing helps. even putting it in download mode and starting odin nothing? also google it and there was nothing. any ideas what to do?
What kernel are you using? It seems like the phone is in a charge only "state"?. You don't say what S6 you have? 920F? If so, try to flash Hacker kernel from here . See if that will help.
I have the same problem.. no recognition on pc only charging.. slow charging...
When i connect a usb otg hub then no recognition for the hub.. only thing pops up in the notification bar is: usb controller connected and then nothing.. tried everything.. secret codes for usb.. all seems right.. but no recognition only verry slow changing.. and damn i realy want to connect with odin for fixing but.. you can fill the rest for your self in..
Try download Shortcut master lite from playstore, run secret code explorer in it, then code 0808, and set AP and MTP+ADB to see phone as disk in windows, this helped me, hope it will help you.
Offcourse you can also try dial *#0808# and see if that works (rom dependant)
Thank you for answering!
To bad that i already tried it.. and still nothing happens

Send it back to Samsung for a warranty repair. Seems like your usb-board and/or mainboard has a problem. I had exactly the same problem, only slow charging. Got it back with a swapped mainboard and new USB-board.
Thank you! Now i know it for sure! I go to samsung with the device! Thx
I have the same problem. I send it in for repair under warranty but Samsung told me that "every change of the original software (it doesn't matter if the problem occurred because of the software change) leads to loss of the warranty." They wanted to charge me 490$ to fix the problem. I denied and changed my daughterboard by myself but the error is still there.
I think somehow we f*cked our Mainboards up.

[Completed] Galaxy Tab4 Firmware problem

Hi All I wonder if some kind soul can help with a problem I have with a Samsung Galaxy Tab 4 10.1. (SM-T530) when switched on it displayed the Samsung banner after this the pretty Samsung logo appears with like coloured spots flying around it, I have not seen this Samsung log before and I wonder if this is some indication of the software it is trying to run.
After a short while a screen appears with a message in "SPANISH" which translated says. "data partition is damaged. need to reset your device to factory defaults. so all data will be cleared" at this time the up down volume seems to work as should, and displays the slider graphic. Other things seem to work OK with this screen when buttons are pressed they make the squishy noise.
I have tied to get into the boot recovery screen but get a graphic of the Android for a second then the Android on its back with flap open and the triangle then the thing reboots.
I can enter Odin mode but when I try to recover the device with a load everything seems OK with the initialisation until the start of the flash then I see "MMC: mmc_write fail" on the Tab.
I have tried different PCs, different MS platforms, different USB leads and ports. Kies sees the tab seems happy downloads latest software then same thing again "MMC: mmc_write fail" I have no idea what software was on the Tab, I also think that there is more info available on the USB port which I cannot see.
When I plug the Tab into the USB port of my Linux pc it is seen in "Places" as Samsung tab but when you double click on it an error message comes up on the PC "unable to mount file" could some one with some engine room knowledge pleas help.
Try to flash stock firmware with 4 files & with pit too , if no luck then center services its better for you ..
Good luck ,,
Hi Thereassaad, Thank you very much for you reply to my post. I have tried your suggestion and this has failed to fix my problem, I also tried to run the .pit file in Odin but still the same results, I did suspect that my problem could be a hardware issue as I have read in other posts that there may be a problem with memory damage under some types of memory write operation although I am not sure that this applied to SM-T530.
I obtained this Tab from ebay as a project in self learning and I have had plenty of fun tinkering with it already. I have found that there is not much in-depth information on the web about the architectural structure of the firmware on Samsung devices but I shall continue to tinker. The Tab I have has no indication of being tampered with ether by attempts to root it or tampering with the innards. I only want to return it to stock Samsung firmware eventually. I do feel that the firmware is unable to write enable the flash and I am still not sure whether this is a firmware or hardware issue.
I am going to try a comms program to see what information is available at the usb connector as there is quite a lot going on which we do not see with Odin and Kies such as serial number confirmation, firmware versions, etc. I may try to use my comms program as a sniffer when Odin or Kies talks to the Tab on initialisation.
If you or anyone else has any good ideas, I would love to hear
Thanks again for your help.

J7 clone Mtk6580 bricked with wrong Preloader

we know how it gets bricked with wrong preloader, i just happened fast and i forgot to uncheck that box out. when i connect the phone to Win7, and i check the device manager, isee an icon with name of Mtk .... ...., screen doesnt turn on, at all, i dont think its charging too, i have backed up its old firmware, before i flash, now i only need a split moment to get pass the wall.
its now a week that im working on this piece of metal, done few things, looking for ways so i can unbreak this,
1) sp flash tools done with all possible combination of keys at the start of flash, didnt work so i checked for a box that can do,
2) found out Cm2 dongle can and i bought it, trying it, it says evertime, on different actions,(flash, format, read file, wipe preloader, well ever possible keys i tested) didnt work with an error
"cm2 memory-emmc validate fail"
after that comes another line saying initialling memory.
and there was another way for cm2 dongle, it was miracle boot cable. i made it myself, again no luck.
3) i did use tp too, i connected Kcolo point after i hit the flash button to body, for a momnet, sometimes does the trick, not in this case though. searched some more and came across a post in Xda forums, someone claiming to connect Kcolo point to something (i only could think thats backup battery, didn't specify in the post, just a picture) for more than 5 second and some other stuff that i couldn't understand.
https://forum.xda-developers.com/showpost.php?p=32424838&postcount=616
this is so far i could do anything, and honestly i i donno what else to do, or how can i not damage this phone. thank you so much for taking the time to read/answering my Question here. appreciated
