[Q]How to read kernel output from UART cable ? - Hardware Hacking General

Hello, I've made a UART cable and used it with note 2 (I used 610~619K resistor in case you're curious) and I was able to read from bootloader but there was not output from kernel

}
so what should I do to read kernel output ?
one more question. I've tried to use the cable with my samsung galaxy star gt-s5282 but it didn't work so I tried different resistor values from 150K all the way up to 619K and it still the same. so I tried to use 300K to see if it's gonna enter download mode but it didn't work too. should I modify something on phone's board to be able to use the cable ?
thanks in advance

Static electricity.. have read about it in some guides and articles..
The best would be to use a magnet attached to your USB cable. That should prevent shutting down... Digital camera's usually have included this kind of cables.. It's even required to meat some ISO guide-line

Use a USB cable with that bulky thing attached to it. Some network cables have them too... maybe you can take it off easy..
DO NOT USE A regular magnet!! it's too powerful and might damage more than you think!
thnks, ill try it and get back to you....

Glad you have it fixed. However it may be because you have your SIM in the Uni whilst you are trying to flash. I found this happened when I was (incorrectly) trying to flash a ROM of a different language/region.

Please compare the photo samples and say which is the best..

Hi Guys,I have used 3 different camera apps to take this picture,I need your suggestions to select the best app..Please guys reply to this post...Just say your opinion..All pictures were taken at the same time..

TEST POINT method

Hello, everyone.
I have something like the one in the picture.
I wanted to do an upgrade and .... bricked - only black screen.
I read about the TEST POINT method. I found this point on my board and. what next? I've read that I have to short it with GND - but for how long? with power on or not? if I short it with GND, can it be from power supply or some other on the board?
Can someone of you show me how exactly I should do it?
Thank you for any suggestions.
