I understand that U fw does not lock any frequencies and will work on all bands. The sim cards i am using are micro as needed.

I saw though,that you participated in the discussion from the other post i mentioned,but haven't read it through all of it yet. A user there stated the "ims not registered" issue.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
If your phone is unlocked then IMS not registering is also not a factor. IMS is per network. IMS is the gateway for VoIP and volte and all carrier IP services. It literally means IP multimedia system and would not result in you having a 0 connection icon. I'm also wondering on area. Is your area good reception for other devices or is it weak.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
The current sim i am trying has good reception here but generally not the best i could have.But not out of the grid situation.

I am more concerned about the options in network operators that i cannot change anything and it pops up errors.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
You say it has your carrier APN. But for sure it has no APN for Greece on board. The phone was US only and I've seen the APN list with my eyes inside the file system, none are Greece. Have you looked up and tried to add your carrier APN?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
The newer sims have APN settings already installed in them so when you put them in,the phone takes them by default. I did not put APN settings,even if i change sims which are different networks,APN settings change too.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
They don't always take with success.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
So i have an unlocked from AT&T phone which in a different scenario,would prompt me to use unlock code in case of using unaccepted sim card.

I cannot use any networks though,because it does not see any and it won't let me choose it manually.

I am stuck with a cool device but no a working phone. :(

Thank you for your time,if you come up with any more ideas,please let me know.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
What is the carrier you're trying to connect to.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
I tried to connect to 2 different carriers.

1. Cosmote Greece,which i called to their service and told me that none of the network service providers in Greece lock or list IMEI numbers.

2.Vodafone Greece,which i had sim installed when it first booted in U fw and for a moment tried to register the network when first booting (restarted on it's own) but when it opened again,i still had the same problem.

The network that was working after AT&T code unlock was Cosmote.But since U fw does not lock carriers,any sim i use,must have the same results i understand.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
At this point i'm thinking some odd hardware issue or it didn't properly unlock. If you're sitting with a useless device then it's worth i guess going back to an AT&T firmware with the sim in it to see if it prompts or does anything weird. Makes no sense to me what is happening to you. The software is good and has worked on probably a thousand or so users here. So.. if you've tried different cables etc and it has only registered on the network once maybe it took some micro voltage and is damaged? It's just odd what you're going through and something doesn't add up with the data we have.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
I came to a horrifying conclusion yesterday. Before updating fw i had a broken screen, which i had it replaced to a service center.(not official service)

I did not notice it at the time because i only run the visual tests (and they were all fine). As soon as i got the phone back i did the fw upgrades and then i realized the gsm network problem, so i linked it with the software. I am almost certain that this is the case because i have been searching for days this issue, and i saw in this forum, another dude that had (the radio off) problem and it occured to me.

How dumb of me.

Afterwards you also pointed it out so i am now at 90% sure of this.

Do you know the location of individual internals of the phone? (for ex. gsm radio location)

I post some images also.

I knew some piece of data was missing. They probably didn't reattach the antenna ribbon. They repaired it man, take it back and make them attach it. This is for SURE the issue.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
So it is not a fried motherboard? If it is as simple as this it will be great news!!! [emoji1] [emoji1]

I hope this works! Thank you man for your time!

I'll post again when i have any news!

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
The motherboard is posting the OS and soc is working etc for all functions besides radio, all data points towards a physical connection. They just didn't properly attach the antenna ribbon, almost for sure. Also don't do this on your own you need several tools and experience. Not an easy phone to work on, make the place you paid complete their job.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
-- side note -- if you go asking for help always include details. It would help to know from the start your device had been disassembled recently. :)

I took it to the service center,told him what i thought it was,he did not like it.

He asked me what i did with the phone because 2 weeks had passed from the first repair,i only told him that i only got an OTA update,( i was sure that the more i told him the more negative he would be.)

He told me after the inspection of the device ( he also opened it again and all was fine) or so he told me,that the software is the issue (change of baseband) and when he repaired it the first time he also checked all the functions of the phone,such as calling.

I really do not know what to do now because i cannot go back to v2 baseband,i cannot open the phone to check the hardware status.

Do you have any ideas left?

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Did you see him actually open it? The mobile phone repair business is not one I trust very much. They are always on defense because customers are always trying to blame them(my friend owns a shop) and at the same time they are also making mistakes because they pay low and don't always have high skill workers(sometimes they do). It is hardware. I can for sure tell you this. Baseband jumping and flashing a million things is a waste. You don't need to go back to v2, AT&T has moved off of that also. They are also on v4 if you were to want to flash AT&T current firmware but I can almost guarantee it is futile since the only variable I question is if you unlocked it conclusively. If you did and you know it as fact then there is nothing special about an AT&T firmware that is good. It locks bands that you may need, I've not looked at your carriers needed bands but you may want to look and then see what US carrier uses closest to the bands you need. In some off chance the U firmware is having a bug or something you can try a firmware of bootloader v4 from T-Mobile etc. Again, unlikely but possible.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
I did not see him actually open it,he would not let me either way.i too do not trust him of what he said but i cannot double check it if i do not open it myself.

He said that with the baseband change the cellphone could be dead if not done properly, ( i know for a fact that this does not stand [emoji28] ) but i fear if it could damage the radio chip. [emoji15]

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
No. You didn't fry the radio chip. Software wise these phones are bullet proof. Odin / flashing is all a designed function. You are flashing software cryptographically signed by Samsung (that's the only reason it's possible)

Is there another shop near you?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
Yes i know that,but since i ruled out most of my options i start to think the stupidiest cases.

I can open up the phone myself but i do not have the double sided thin tape to close it back again.

All the service centers are near the expertise of this one.

I don't think this guy opened it again, call another shop and explain since the one won't help. Maybe you can get a reasonable price for help? It was opened so it's gotta be this. Nothing else makes sense.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
Until i get it to a store,can i do any combination with csc files or anything else i could try out?

I will call some other service centers around.

Hey man,i just got a call from a 2nd service center and they told me that the chipset of the radio of the mb is fried. I asked them from what but they couldn't say for sure. I asked, could it be from software?, (just to see their pov compared to the other service center) and they said no way. I asked only for my peace of mind and to double check,that it's not my fault.

They said,it might just stopped with no interventions either.

So now i have a bad mb to a pristine externally S7 but i cannot do sht.

I cannot go to the first guy after all this time. He'll say i did it.

I don't know. I don't believe the odds but it is not impossible. It's NOT to do with flashing. Lose that thought. It flashes with success or errors. That's it. If you want to for time nonsense since all's maybe lost flash to the newest att ROM and see if it requests unlock code or anything odd. You can get those on v4 from updato.com
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
This service checked the phone, free of charge.

I don't want also to believe my bad luck,of either fried chip or bad service centers.

I searched online for used mb's or oem but since the screen replacement was 290€ it to steep for me to change mb also.

Should i seek 3rd store? Uhhh i'm tired of this sht.

I'll go tomorrow and pick up the phone,asking them also how they ended up with this conclusion.

Thank you man for your time and help.

Hey guys, I'm sorry to post this on a wrong forum but I can't find any information on flashing unlocked firmware for the Sprint variant of the S7 Edge. Right now I have a S7 Edge of Sprint that is unlocked and using on ATT network. Do I just flash the firmware here and everything should work fine? Any specific CSC or modem I need to flash?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Just follow the instructions and use the files i provided and it'll flash fine. If you want to flash a specific modem etc that is incumbent upon you to do your own research, i don't think with Sprint you should have a need. The only reason T-Mo users do is because it enables 4x4 and 256qam. The phone though on it's own will recognize you're on Sprint and load the Sprint modem. It actually loads the modem for all the major US carriers, the only issue is in the case of T-Mo it just doesn't for whatever reason have up until now the most updated modem(which in the case of T-mo makes a difference) it may be just fine on Sprint and just be install and done. Give it a go. The csc to use is the NON home.csc as it'll full wipe and be the most stable. I've included the home.csc if you wish. It doesn't wipe the internal SD and may work just fine but a full wipe is recommended.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] xterminater07:
Thank you. I am doing that as we speak now hehe.. doing a full wipe by the csc (non-home).
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Sweet. :) I've been on it forever. Stable good stuff, help me keep this phone for maybe another year.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] xterminater07:
Should be able to update to the latest OTA in the future right? I am using this as a back up phone as I have a Note8 :)
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Yup, OTA pulls right down. I think August is the last update, it's monthly now. I like the Note 8 but I'm skipping a gen. I've been a yearly phone whore for a while but I want something that I've not seen yet. I want an unlockable bootloader and root and I'm waiting for either Nokia or OP to do something. Did you do the black nav bar via adb on note 8?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] xterminater07:
No I did not ... is there a better look if it's black?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
People seem to think so. I don't have it and prob won't get another Samsung. I know it can be done but haven't myself.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
Hey man,what's up. I took the phone from the 2nd service center which had told me that it was the radio chip damaged and since then i called 2 other service centers in my area which were crap,because one of them told me that he knew the phone and is a bit tricky to open because it is sealed tight,(i told him yes i know for waterproofing) and he told me that he might break the screen or back cover while trying to open it up! :laugh::laugh::laugh::eek::D ahahahahaha.

The next service center which i contacted,told me that the phone has no service because it is from US and it is locked.I told him repeatedly that i unlocked the phone but he didn't even listen or understand what i said.So i depleted all my options in my near area of service support and decided to order some tools and open it myself to check what is going on.

I tried different fw versions since i got it back but no luck.

Do you think that it could be the antenna

-http://www.ebay.com/itm/For-Samsung-Galaxy-S7-Edge-Replacement-Loud-Speaker-Assembly-With-Antenna-OEM/172221033771?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 (maybe he damaged it when he pulled it out to replace the screen?)

Or the radio chipset only with the issue? I was thinking that it my be the antenna but then,wouldn't the phone had a little or no singal but would try to find some networks?

Thank you for your time once again and if i succeed anything new i'll let you know.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] volcano619:
Wow,kudos to you for trying so hard being a non technician^^

Just went through your conversations till now,i hardly doubt that the chip's been fried,im sure bootloader does a device check to see if everything is running smooth during the boot,and throw a error if any,bcauz if its fried it'll have a significant amount of current flowing..why don't you try showing it to an authorized samsung service centre,if it helps ??

---------- Post added at 05:36 PM ---------- Previous post was at 05:30 PM ----------

Hi,can i get some assistance,i would be getting a 935A device to use it in India,i'm not sure about the bootloader version yet,but i wanted to know the steps to be taken to get this phone to get to 935U,from your first post i understand,i need the Odin,and the U Firmware files,but after that what should i do??,some clarification would be deeply appreciated,i'm just new to these things.Also would Samsung Pay work on a 935U device in India?

Thanks
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] liveuptoit:
Official Samsung service won't even touch it because they say it is an American version and they deal only with European ones. I also don't think that the chip is fried,because i guess the damage would be bigger if something that this would have happened.

If you follow the instructions from the start you should be able to reach to U. I think that Samsung Pay works anyway.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Yup, i always keep the build on my server updated so you guys don't have to take 5 OTA's on first install. There may have been a security update since that build, i don't recall. But if so it'll OTA you to the August 1 security update which is where the U devices are. Hopefully a new OTA to fix Krack etc any day now.

Hi, I'm new doing this (I have never changed the ROM of my S7 Edge), I use my phone in a Mexican carrier, so I'm not able to get the updates and I have to flash it in the recovery and I'm tired of that. I downloaded the Odin 3.12 and the files of tha G395U, but I don't know whick file to use, the HOME_CSC OR CSC_OYM or I have to put both, but I don't know how to put both. Hope someone reply, btw thank you!
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Robjurado90:
Well, I flashed it. I had put the HOME because I didn't want to erase nothing... A fail message appeared me (in the phone screen) when the installation was happening. But the phone turn on normal (it took a lot to turn on because of the SO installed) and in the Settings appeared that it has the G935U. About the failed screen, it can may not be installed correctly?

Edit: Well, the phone is rebooting every 5 minutes, I'm installing again, may be I am going to install the stock if it continues

Use the other one instead of home. Just back up your phone with the samsung sync before you do it and you will be able to load all back on the phone after.

hey billyone1, did you have to root your phone before you installed this rom. So far I've been unable to install it over stock 7.0 AT&T.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] JeffDC:
Followed and used first Odin in OP post: Errors Get PIT for mapping. operation failed.

OP, I am following up with secondary Odin other's have used. How about listing that in your initial post so folks don't have to search through the thread to find it?

Secondary, Prince... Odin, same result.

I've been trying to load this U rom for 12 hours now, and same results, PIT for mapping. Using standard CSC file. Tried Home CSC, same result.

Get PIT for mapping....

It seem straight forward enough that I can return to stock when it flux'es my phone...

I am stumped.

Thank you.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] sunnycee:
My little experience with samsung phone, the likely cause maybe that the version of firmware on your phone is newer than the one posted by OP, so cross check to see if your are loading an older version, i think the most recent version now is G935UUEU4BQJ5, so if your phone already has this xxxBQJ5, it will not work, that means you will have to wait for a newer update to be able to flash it.

Good luck
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] JeffDC:
Sunnycee, thank you for responding. So many posts get no replies. I appreciate it.

Some years ago it was possible, on other phones, to edit the ROM version file and then install over. I have not seen that with the S7's.

G935AUCU4BQA6 I guess I am out of fortune for now.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] sunnycee:
If your version G935AUCU4BQA6, then if you can get the 935UUEU4BQJ5 it will work perfectly for your conversion. But what we have here is....i think G935UUEU4BQH3
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] JeffDC:
Sunnycee, alright, I think I have found it and will try with the newer version. I will let you know how it went.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] sunnycee:
Alright. Good luck
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] JeffDC:
Same error, used Prince C Odin.. It seems the errors have all been having a PIT message. It may be that this phone will not allow anything other than a straight AT&T flash?

Other than the stock, I've tried 4 other U variations with Odin variations. I'm wondering if resolving an FRP with it somehow permanently 'changes' something. After the FRP solution a soft reset is done. I have re flashed many times after that, but the only successful ones have been with stock ware. I normally wouldn't think so but maybe there is an e-fuse or something?

I wonder if the ROM components can be mixed, so use the stock AT&T BL form the most recent, and then the other parts from the U ROM?

Thanks for your suggestions, Sunnycee.

OK, time to load up this phone and give it to my honey.
