UART access on Samsung S5302 (Galaxy Pocket Duos)? - Hardware Hacking General

Hello. So I've been trying to access UART console on my S5302 for quite some time. I followed instructions from here using PL2303HX-based UART-to-microUSB cable and 1MOhm variable resistor. Tried a lot of values from 150kOhm to 619kOhm, managed to get input to the device (I guess, because bashing Enter key while the device is booting seems to make it stop booting), but no output to serial console whatsoever. What am I doing wrong? Any ideas/tips?

Himalaya, familiar and the serial port...

Hi there,
I'm trying to get linux working with XDA2...
At the moment, I use HARET to boot the kernel, but I encounter some problems.
1. USB Serial Connection is breaking when booting the new kernel. I wouldn't have assumed anything different. But the Xda-Developers tutiorials shows how to connect via that virtual port.
2. I can use the real serial port to redirect Kernel Output until it says: "Login:"
I'm using minicom to get the output. But I can't enter the username. I'm sure that I use correct port settings, is there anything special with the connection to the XDA2? Should I use another Application to login? What's wrong with my serial input line?
Can somebody tell me how to use the Serial port via other Terminals? (Linux shell commands are highly appreciated.)
Thanks in advance for some hints!
Edit:
I also tried to compile custom kernel, but after haret switches to the dark screen (after showing the linux logo with splashed eyes ), it isn't redirecting any output to PC.
hi. you should first tell which software versions you are using.
Himalaya kernel is not maintained for a long time, but it's
not very difficult to update it.
Versions I use:
HaRET-0.3.6.exe (http://anymore.nl/ipaq/haret-0.3.6.exe)
zImage-2.6.12 (http://himalaya.lange.nom.fr/zImage-2.6.12)
initrd-2.6.12.gz (initrd-2.6.12.gz)
Hardware:
Processor: Intel PXA263

I9000 modem access
I'm trying to access /dev/ttygs0 and test an AT command
with all possible serial speeds directly from a root console , but
modem seems dead... i cannot find informations how to enable it
Hi guys,
I have following problem with I9000 - when new SMS arrives there is no notification to serial port.
With command AT+CNMI=2,3,0,1,0 there should be such notifications, but they don't arrive to the serial port.
Can you advice me someting?
For people who have asked me.
I accessed the AT commands by putting the I9000 phone PDA/MODEM setting on MODEM and then connect a USB cable. The phone causes new COM/tty ports to appear on the PC when running Linux.
sending AT commands to my Galaxy S
Hi there,
Im trying to access my My Galaxy S (Android 2.3.4 XXJVQ) as a GSM modem and send it AT commands.
Im using Windows 7, I cant seem to get this to work, whether through a cable or Bluetooth i can see in the phone in devices & printers dialog and it does list its modem as a feature and tells me on which port its connected, for USB its COM4 for BT its COM6.
However if i use Hyperterminal it wont let me type anything into the textbox, it just doesnt respond.
I also wrote a small C# app based on code samples i found online but it never seems to respond to the commands i send to it. If i use COM3 for my "Thinkpad Modem Adapter" and i type into my console app: "AT" or "AT+GMM" for example i get a response back. if i use the port for the phone (COM4) i get nothing back...
I tried the trick with setting the phone from PDA to Modem using *#7284# but then when i connect the phone to the PC it wont recognize it and in the device manager it shows me a device called 7CDCs which it cannot find a driver for.
Ive also tried PDANet, i got the computer and phone connected together but i still cant issue an AT command at the modem...
Not sure whats the problem here...
If anyone can help me with id really appreciate it.
thanks!
Yoav.
You need linux to make it work.
You might be able to find a windows driver for it, but i don't have windows so i can't help there.
Can't test this just now as I'm at work, I did get through to the modem on windows 7 via usb. I'm sure I had to issue a reset command before I could do anything else.... ATZ maybe? I'll check it out when I get home.
Yeah, with the phone in Kies mode for usb connection and using PuTTY instead of hyperterminal (no longer provided with Win7) I got through to the modem on COM3. Whether the phone responds to all commands as expected seems to be another matter.
Thanks fahzat,
Ill give it a try again with Putty but i did try Putty yesterday as well as Hyperterminal and got to the same situation where it seems to be connected to the phone over the port but then it wont allow me to type anything into the command prompt... You chose the "Serial" type connection in the Putty initial screen right?
Correct, serial connection on COM3 (obviously your port may differ) with speed at 921600 (9600 seemed to work too). In the "Terminal" section set "Local echo" to "Force on" or you won't see what you're typing, only the response.

Or make the first command you type ATE1
Thanks guys, it works. now im able to send commands to my Galaxy S.
What i really wanted to do was to manage to send SMS messages and see incoming messages but following the commands shown on a few tutorials dont seem to work with my phone.
Wondering if anyone knows how to do that with the SGS (I9000)???

Achieve AT Command from Android
Hi All
I read that is not possible use directly in Android AT Command to debug the modem, but I was thinking to write an APP that using the USB Serial Virtual port in Android could send the AT Command directly to the modem. I read about external API to use serial communication.
Do you think this is possible??

Hi Midas5,
Could you be more specific?
a) So you set it to use: UART as MODEM and USB as MODEM??
(Those PhoneUtils settings are confusing!)
b) Which exact devices/ports appeared on your local machine?
c) Which exact devices/ports appeared on your phone?
d) Can you say anything about the device driver that you're using?
Thanks.

This is probably the wrong modem. It's most likely your laptop's built-in FAX/modem!

[Q] Kernel serial console

Hi guys,
I'm looking for a way to read the kernel output during the boot process. I've already tried recompiling the kernel with/without FIQ_DEBUGGER, KGDB_SERIAL and SERIAL_SAMSUNG (_DEBUG), as well as setting the kernel console in the cmdline to every possible /dev/tty* port without any success.
I also tried echoing in every available serial port and use a digital analyzer on a breakout-microusb board to monitor the output. But all of the tty devices seem to be disconnected from the USB port. There are a lot of hints on the internet for other devices, but the most of them use a dialer to get into the service menu (e.g. for smartphones: http://forum.xda-developers.com/showthread.php?t=1515570) or a jig-cable with a resistor between ID and GND (http://redmine.replicant.us/projects/replicant/wiki/SamsungSerial). Both approaches failed on my Nexus 10.
I got no clue what to do next, so I would be very appreciated for any hints or new ideas.
I dont know much about kernel debug code stuff, but there is this command to see kernel messages in real time:
-adb shell watch "dmesg | tail -40"
Does that display things during bootup?

Thanks for that, but as far as I know the ADB daemon is started only after the kernel initialization. I can read the dmesg after Android is booted, but it doesn't help me to debug problems if the kernel panics.
I think I need some kind of a correct serial cable to read the kernel (and bootloader) output, but I couldn't find any working method for N10.
Did you have any luck with your case?

Debug USB

Hi I have a S5 Neo, practically it is broken me the display and it is not seen anything, but the device correctly works. From different guides I have read as to activate the Debug to broken screen, and it would serve me the custom recovey (ClockworkMod) to use the commands adb shell, therefore to activate the debug. The ClockworckMod is not compatible with my telephone as, another way it exists for using the commands adb with broken screen? Thanks

I bricked my HD 8 2017 after downgrading from 5.6.4 to 5.6.0.1

Hi, i was happen to wander around the forum to find a method to root my HD 8 2017, and seems that my tablet has automatically update to the point where root is not possible (the current version was 5.6.4.0 build 636559820), therefore i tried to downgrade to 5.6.0.1,since the root method only covers the 636558520 build version, and after using adb sideload, i found out that the device has been totally bricked and can't be turned on, after a few googling. i've found the post about debricking, but requires me to short the TP28 circuit (which i don't know where it was after removing the cover), so i use amonet and it still didn't work, please help!!

Wow my PM
Please don't pm me for this things, create a thread as you done or ask in the UNBRICK thread.
So about your error..
Mean that you're in Preloader Mode instead of BootROM Mode:
Code:
RuntimeError: ERROR: Serial protocol mismatch
Be sure to have modemmanager disabled.
Try to short again, it can take a lot of tries (For me like 20+).
If still no, change the object that you're using to short.
If thse same, try other USB cable and other USB port (BETTER 2.0 instead 3.0).
If after try all the suggestions still the same error, do the process with the battery disconnected, that worked in most cases.
Cheers!

Thanks for replying! But can you be more specific about the short process? since i don't know where is the CLK test point of the board, the original guide showed that it is near the the emmc, it would be nice if you can show me the image of where to short on the motherboard? And about the Preloader mode? So i have to use the brick-9820.sh to confirm the brick then proceed to bootrom-step.sh?

No, you don't need to run any brick.sh since you already bricked but in the WRONG WAY, so you need to short TP28.
If you search a bit, you can find the TP28 image
https://imgur.com/9ThIUqK (The Light blue one) (thanks @<br />)
You need to short that point with something conductive as a paper clip or a little or a small cable with bare ends.
One end of the object you put in TP28 and the other in any place with metal that is on the motherboard (a screw for example).
At same moment that you're doing this the script should be executed and waiting for handshake the bootROM:
Code:
sudo ./bootrom-step.sh
After that short the point as described and connect the tablet into the computer AT SAME TIME. If all goes OK it will ask to remove the short. Remove it and press enter, the script will do the magic
If you still getting the Serial Protocol error, use my suggestions of my previous post.
That's all, a bit tricky but has solution
Cheers!

Well since the method here is almost unusable, i was thinking of flashing the .bin file of my Fire using MiracleBox, maybe this could help with my problem: https://www.google.com/amp/s/ifindhub.com/flash-bin-firmware-files-mediatek-device.html/amp

Dude...
That box comunicates with Preloader which is patched on Amazon tablets.. If it were that easy we would have rooted this tablet many years ago.
About your problems, seems like a LCD cable problem. Unmount again the tablet and check all cables, specially the LCD one.
Cheers.
