Modem problem after rooting.(SM-G935K,S,L) - Samsung Galaxy S7 Edge Questions and Answers

Hi, I am an RF-Engineer in Korea.
I have measured rf condition with GS7EDGE. but after rooting I could not get any modem logs via "samsung usb serial port".
Is that due to warranty voiding? Have any idea?
Thanks in advance for your attention.

KIES WON'T ACCEPT IMEI - S4 i9505

I am trying to update firmware using kies:
on log-in to Kies it asks for Device name... and the S/N (which i assume is the imei # )
i have acquired the IMEI in several ways, (there is no label in the battery area)
a) dialing *#06#
and
b) via settings>more>about>status.
both no's correlate with the same 15 digit number
( i also back searched this number imei online, and it confirmed it's a GT-i9505 )
HOWEVER kies won't allow me to log-in, telling me it's an invalid S/N !
p.s. one further question:
the about ‘about device’ gives a 15 digit number, whereas calling *#06# it adds an additional; ' space/space03 ' which i see in the settings ‘STATUS’ section as the 'IMEI SZ' is this significant? I have tried entering both the 15 digit, and the 15 plus the /03
but all attempts have been rejected
is there some secret way of entering the S/N ?
any assistance is appreciated
The imei from dialling *#06# is just the first 15 numbers which are to the left of the slash.
If you are sure the phone is a 9505, download and flash the firmware from sammobile.com.

thanks for the reply audit',
that's what i was attempting to do, using sammobile, and ODIN, but got a 'partition failure'...
so i tried KIES, but KIES won't accept my imei.... (the 15 digit number)
a simple 15 min job is proving to be a PITA
Are you using the original Samsung cable? Tried different usb cables and USB ports?

i bought the phone without a cable, initially i didnt realise how critical the cable was, so i bought an accessory USB cable online, finding that my phone was un recognised. so i spent ages assuming i had other software issues etc. then i read about trying other cables, so then i bought another 'genuine' samsung cable (or so they said), this was no better, and my phone was still un-detected. i am awaiting a replacement as the seller claims it is genuine.
in the meantime i found an old micro USB cable in my bit's box, i think it's an HTC,. anyway suddenly my phone i visible on odin and kies, but i am getting imei issues on kies and partition failure on odin...
so the short answer is no it's not samsung but it appears to be working better than my other psuedo 'samsung' cables.
yes i have tried all USB ports, only 2 on the acer aspire.
Serial number is NOT the same as IMEI.
Kies is asking for a serial number and you giving the IMEI WILL cause Kies to fail.
Your serial number is on the sticker under the battery and also on the box the phone came in.....
It will start with
S/N......................
Edit.....If you have Kies, then you have USB drivers, but here is a link to the *latest* [as of 25/6/16] usb drivers (pulled directly from Samsung's own website).

The partition failure in Odin could be due to the USB cable.
I have the s4 i337m and Odin fails to read the partition information without the original Samsung cable.

cheers 'keith'.... i was following a tutorial which suggested it was the IMEI that should be entered. it was all made harder as there is no label on my phone, however i was referred to the app 'phoneinfo samsung' so have all the info i need now., hopefully
thanks 'audit'... the cable issue is holding me up at this stage as the one i bought as 'original' turned out to be a fake, guess i shouldn't be surprised ! i'll borrow one from a friend and try my luck
thanks for the assistance guys, it's certainly a minefield

Unknown USB Device (Device Descriptor Request Failed)

Hello guys,
after trying everything I could imagine and find on the net, I still didn't get my PC to recognize my S6 edge plus.
Hopefully someone od you has got some more ideas.
The Problem:
Connected Phone shows "Unknown USB Device (Device Descriptor Request Failed)" in the device manager. No MTP connection and no ADB possible so far.
Done so far:
Samsung USB Mobile Drivers
Kies
Smart Switch (with reinstall of drivers)
6 different cables with 4 PCs (2 Win10, 1 Win7, 1 Linux)
USB-Debugging on / off
*#0808# switched through every mode
USB-Hub drivers
Factory Reset
More Info:
5 of the 6 cables are working just fine for data connection with my S3
There is no infobar tooltip to change USB mode at all, just telling me it's loading
In Download Mode the phone doesn't get recognized by Odin (with same cord and USB Port the S3 does)
In Stock Recovery Sideload Mode the Device does not show up in adb devices (with same cord and USB Port the S3 does)
Regards
up
I'm guessing you have downloaded and installed the Samsung drivers?
New Infos on this case:
Local tech support inspected the phone. They suspect the mainboard to be defective due to corrosion signs.
Of course the repair cost would be ridiculous.
I'm gonna repair it myself, but I'm not quite sure if it's really a faulty mainboard.
I rather think of changing the USB board first, because it's like a 10th of the mainboard and more likely to get wet if that's the reason for the damaged phone.
Any ideas??
Regards
You didn't mention if it charges via USB?
Im in the same situation..
charge via usb but is not able to recognize the phone in any computer (a lot of different cables with 3 PCs)
My unit was wet and i think that something is wrong for this reason.

Hi Cento50. Have You managed to get the phone to work? At first my phone was showing up in "This PC" on Win 10. but after trying Samsung usb drivers to get Odin3 working now it is the same as Yours. Shows in Device Manager as: Unknown USB Device (Device Descriptor Request Failed). A strange Conundrum.
Hello @Photobil2012 yes fix habe worked!
One little wire have replaced 2ohm resistor.
And have fix fast charger and data comunication with PC!
We i have repaced first one diode.
Phone a this time work complete.
First this problem i have connected one hard disk to otg cable with phone battery low!
My suggestion Please caution to use otg interface with high current if have low battery in the phone.
This cause high current drain and possibile burn diode and resistor.
Hi Cento50,
Alright! Thank you very much for the most timely reply and tech info on the successful fix. This is very good news to receive. I just replaced the battery so it is brand new and that works fine now. However, if it is necessary I can apply the same type of fix that you applied. Great work, and thanks again for your help.

Device not recognized error

Whenever I plug my phone into my pc I get this error. I tried 3 different computers and 4 different cables. I installed the Samsung usb drivers and adb drivers and I still get the error. I've had some people tell me the problem could be the cable, the charging port on the phone or the motherboard. What's wrong and how can I fix it?
Hi can you please provide more information on your issue like the specific error message??

Flashing g930v with bad USB?

I have a g930v that I need to get U or T firmware on for wifi calling. Problem is the USB is apparently bad. Charges and fast-charges just fine. But when connected to the pc it shows the device is unreconized. Happens on multiple pc, port, and cable combinations, all ov which my Tab S2 will connect with. Is there anyway to flash through ADBlink terminal or from SD card without using Odin or get the PC to reconize the phone (doubt full if the USB port is bad)? Tripping Knox doesn't bother me as I don't use Samsung Pay and the phone is clearly out of warranty and it will be used until it dies rather then traded it. I have file sharing turned on, adb dubugging is on, OEM unlock is on, USB configuration is set to MTP, verifify apps via USB is off. If I manually update the Microsoft generic driver with the Samsung driver I get Code 29 so I now the phone isn't shaking hands with the PC. Any thoughts would be appreciated. Thanks.

either you have to change the USB chip on the system board or change the whole board, changing USB port/charging port wont fix this issues, and you can't flash without odin.

Thanks for the feedback. So it most likely the system board and not the charging board. Bummer. I am going to guess there is a 250% chance that it is a bga layout also. Looks like I'll suffer until I can grab a new phone. Thanks again.
