I loaned my friend my old s7 edge and she said she got a blue screen of death. She went to a samsung repair spot in Best Buy that was authorized. She dropped it off and the tech called saying the logic board went bad. So I just ripped out the board in my S7E to replace it but before buying a 935v I was hoping i could buy a 935U board since its unlocked. Just wondering if anyone has done or confirmed this would work. I used to do this all the time with LG devices but not sure on this device. Thanks.
The reason I ripped out the board is because the phone would not power on, go into safe mode, recovery, bootloader, nothing. All I could get was my surface to recognize the SD chipset as MSM8996 when plugged in.

Well I guess it doesn't matter because I can't even find a 935u board only the 935v.
Funny thing is that the board in the pic is from an AT&T model, SM-G935A. Probably it was flashed with U firmware at some point... and bootlooped. The "A" bootloader has a higher number than the "U" or "V" and it cannot be flashed over.

I thought the same thing also. But underneath that it says /v/ and other letters. Seems to be the same board for most carriers. This was original from Verizon.
It is possible, but there's no U there.
I have flashed my V with U firmware and it worked fine, even got the U official updates after that. So it might be indeed the same board with different firmware on.
When I change the SIM, the phone re-flashes automatically a different radio modem, with a different CSC code.

HI guys,
I bought an ATIV S in Malaysia running on stock rom and not bound to any carrier. Changed the CSC to ATO and updated to GDR3. Used the phone for few days and then sent it to my brother in another country with a different time zone. When he tired to put his sim the phone can't detect it.....sim card missing. He tried multiple sims but all not detected.
I am confused as what could be the reason since it was working fine in Malaysia. What shall i do ?

First of all, this is the Developement & Hacking section. This question belongs to the Q & A forum, where it will be answered. Please only post relevant threds in Developement & Hacking.
To answer your question:
Has he tried a hardreset? Maybe this is a bug related to the change of the CSC.
Are you sure that the phone was not damaged in any way while sending it to your brother? Let him take a look at the SIM-tray and see if a pin is missing, broken or whatever. This happened to a friend's phone just recently.
If nothing works, try to flash another ROM. If this doesn't fix your issue, it is most probably a hardware defect.
Sorry for posting in wrong section, guess i was in a hurry n didnt realize dat. Btw d problem has been identified n it turns out dat d sims from local carriers r different n d chip does not really come in contact with d pins due to different dimensions. In pic top 1 doesnt work while bottom one works.

Hey guys, need some help... My mother owns an G2, in phone info and on the back it says that it's D802 but when I checked the IMEI number on http://imei.info it says that the phone is D800. How can I know which model is it exactly? Have to know because I'm going to take that phone and use it...
Wouldn't want to brick it since I'm a flashoholic

Tried to look up for the sw update on the LG Firmware site with the IMEI, it sayd "invalid IMEI"...
Nah just check the phone model number in setting -> about. then youre good. I had D802T and i ran imei checked it obviously wrong. It says mine is D800 and is 32Gb version but in fact mine is 16Gb. And yes i take out the cover it says D805. I guess some part could fit on each other.
Just wached some g2 teardown clips on youtube... One of them had all different parts, speaker from d805, motherboard from d800, and the model was d802! The last one I watched was made by a Russian dude, everything was from d802 but when he removed the ribbon, I look at the motherboard, poof! D801! This can be a big problem because if you need to flash your phone with a KDZ, in case you have a different motherboard, you will surely brick your device! This is the moment when I don't know what to do... :-\

Then the answer is obvious. You need to check your motherboard model and that is your reference. If speaker and battery or even backcover from different part i think it no problem though. I just opened again my phone and my phone frame says "D801/803". But until now i just flash rom for D802 variant and everything gone well.
I had purchased an I9502 through olx.in, last week.
Second hand.
Due to rare users, there is no dedicated thread on XDA for my device
Now, many questions arises.
I had updated to official lollipop (5.0.1), by SAMMOBILE's official ROM. After upgrading, my second SIM cant connect to network. So I revert back it to KK (4.4.2). Still the problem persists !!!!! . I couldn't use it as a dual sim phone Is PDA and CSC version is important while flashing? or we could install any PDA/CSC rom version on samsung phones? I don't know the original ROM so, I had downloaded all firmwares available at sammobile and tested. only 2 of them managed to register my SIM(first) on network. Is it a hardware issue? or by a wrong ROM ? anyway now my mobile admitted at hospital and specialized doctors have been studying his disease
Is there anyone using dual SIM without any errors?
The PDA and CSC are vital to ensure you get the right regional variant for your device. The only exception is if the phone is unlocked for use on another carrier, in which case you can use a ROM from any region. Where you have the dual SIM version however, you only have one region available to you, but with multiple Android versions. The firmware here is the latest for your device. Do a factory reset before flashing through Odin.
I am totally disappointed.
My technician said that it had lost IMEI !

What will I do?
Is there anyway to recover its IMEI?
I had followed all guidelines available through search.
But, I couldn't...
Please help me on this....
Flash just the modem through Odin. You can extract it from the firmware download. Sometimes the modem needs to be flashed twice before everything functions correctly.
Other than that, I'm not aware of anything else software-wise that can be done. You'll need to take the phone to Samsung themselves and have them look at it.

I had the same situation and it worked
I am trying to register my phone onto Samsung's website but there are a ridiculous amount of variants of the SM-G935F.
About > Settings only appears to show "SM-G935F".
Any ideas?

Wrong.
My 'Baseband version' is G935FXXU1APB2.
That is not on that Samsung list - probably because it's not asking for my baseband version...
EDIT: The SamMobile Device Info app on the Play Store found it for me.
I don't know exactly where you will find this information, but they are related to the version of software installed by the carrier - for example, the EVR variants are supplied by and locked to EE, the O2x variants are supplied by and locked to O2.
Mine came from the Carphone Warehouse - they tend to ship phones that do NOT have the carriers own software, and to confirm this, mine is the top variant in the list (ABTU). I registered my phone online using my phone, and it somehow auto detected the correct variant.

Goodday folks, i happened to stumble upon something on multiple occasions while opening my Moto G4 2gb/16gb Amazon variant for swapping boards or internal components. While observing the motherboard, i recognized down by the sim card area there are two sim slots. Upon curiosity, I tried putting the sim in the second slot with no luck, it won't read ! I've tried on stock nougat ROM and even on my favourite ROM Arrow OS pie. the sims just won't read in the other slot which is BTW hidden behind the screwed on back cover. Does anyone have any ideas if there is some software exploit or method to get both sim slots to work ?? .

We had this discussion/observation 2018/2017 you'll find it for sure.
Since there, I can't remember that someone get this managed. You'll need a low level software or a hardware change maybe. But it's not possible by fastboot rom as we know(you'll brick it if you flash wrong firmware).
