Galaxy S7 Flat -- no signals after flashing Rom? Plz help - Sprint Samsung Galaxy S7 Questions & Answers

Hello guys,
I've started to freak out a bit now as I can't get no signal on my S7 ( GM-930P) whatsoever.
I had my phone running ok ( living outside of USA ) everything seemed fine.
Flashed the GM-930V firmware to jump on the Nougat beta ( everything worked fine n sweet )
Wanted to try the Custom roms ( Eco signals worked fine ) experienced FC and insane batt drain
Tried the Stangfire customrom v2 ( signals worked fine ) experienced a weird UI glitch after rebooting
decided to go back to the Nougat beta as it felt a lot stable and the batt life was great
Now that's where things go south for me. I had no signals at all and my sim card doesnt seems to be recognized at all
i tried all sort of things after that. flashing back to sprint firmware / verizon / nougat beta / custom roms all works fine except i have no signals whatsoever trying diff roms on the signal bars it either shows a " X " or a " Circle with a line through it "
when i try to perform any dial codes in the dialer it doesn't seems to work either eg" *#06# " it doesn't brings up the imei window it just stays there and when i hit the call button it pops up " Mobile Network no Available "
it must have something to do with the baseband or the radio maybe? can someone pls help me with this ?

anyone

Have you tried going back to a stock sprint firmware?
Sent from my SM-G930U using XDA-Developers mobile app

Yes I have jumped back to every single firmware stock ( sprint, verizon, the G930U ) Nougat beta, Custom roms everything works except the call service i get a cross over the signal bars and the moment i insert a sim ( tried 2 diff carriers ) i get the " invalid sim " error msg pop up.
Am not living in USA and i have bought this phone locally it was working fine. I can't reactivate it with a Sprint sim for obvious reasons as am not in USA

Well seeing as how you bought a sprint version s7 there's a simple answer being you f***** up. It's a locked bootloader. Have you done no research before attempting to do any mods to this phone? I have nonsolution for you but I wanted to. Comment on how your stupidity ****ed your phone up. You're the problem with society. Oh cool new phone I'm gonna do a bunch of.stuff and make it awesome etc and then you **** it up and ***** and moan looking for someone to fix your mistake. If you had any common sense you would have done some research first. I hope your phone doesn't work ever again.

well first of all thanks for taking time and reading through but dude am not the reason why he/she left u lolx chill. I actually did flash the phone on diff firmwares quite successfully from Sprint to verizon to the G930U even did the Verizon to Nougat beta update from there got back to sprint and then installed a Eco custom rom. So for u saying u can't flash ( don't know what u mean by mod ) this phoen i think u need to grow some balls and try. It actually works has nothing to do with a locked bootloader i wasn't trying to flash a custom recovery. I did somehow get it into a locked state somehow i agree but not cuz am so stupid not to read through ( if u use your common sense what u advised to me ) many of the posts and threads actually say this and this firmware for this and this variant of the phone.
Chill bro and am sorry if u got your phone f**** up the same way. It would have been an easy fix if i was living in the US just plug yr sprint sim in activate and u are back in business. In my case i can't do that but i can still get it back working if i pay a certain amount i just was just trying to see what chances i have got to get it back accept my sim without paying so am really sorry to let u know my phone would get back fixed

Show me this research he was suppose to find saying he'd lose call capabilities once he switched to different fw on his sprint s7 using an international service provider... Root research is limited on this device if no one tries anything new there will be no development on the device. You want to be scared and keep ur device not "awesome" fine but don't put down someone cause they asked for help.

Exactly there is always going to be someone to test the waters so for others it's clear not to do the wrongs we did and that's how it works . I still am not sure what triggered it cuz i did try out every single firmware and the 2 custom roms " Eco and Stang5liter " as far as i can remember I flashed Stang5liter custom rom and i was on the G930U firmware ( i think that rom was meant for Verizon firmware )
Rom Version:
G935VVRU2APEI[/COLOR]
Model number
G930V
Android security patch level
August 1 2016
Baseband Version
G930UUEU4API3
i think this is what caused the phone to go back to it's locked status as the baseband didn't match/was more updated than the Rom build ( totally my mistake ) maybe something ppl should be paying attention when flashing to a custom rom

Damnit Futuretel

So I just got my Sasktel phone back from Futuretel.
waited over 4 weeks.
I turn on my phone, goes to main menu. ASKS FOR AN UNLOCK CODE!!!!!!
Sasktel doesnt have a network lock. I work for Sasktel in repair , and theres nothing we can do on our side.
I called Futuretel, and after waiting for half an hour, I get a msg telling me that they cant do anything, and that I will have to send the phone back.
Anybody know if reflashing a new JL2 will remedy my issue, or is this network lock tied to the mainboard itself?!?
how about this
http://forum.xda-developers.com/showthread.php?t=913681
and you posted in the wrong section of the forum by the way...
out of curisoity, would reflashing a different firmware change that lock? Or is that something tied up to the mainboard?
I was gonna ODIN in a new JL2 and hope it fixes!~
You can unlock it with one of several apps on the Market but you shouldn't have to unlock it if it is a SaskTel phone (on SaskTel's network). Maybe check the product code and see if it is maybe a Bell phone they sent back.

yes, buy the SGS unlock pro app for $5
it works
but the guide i liked is even easier, just go in and delete the files, and it works, FREE!!
make sure you make a backup first
That guide is really long and complex (all the root commands), unless im missing something.
I saw your comment, but Im not sure I understand if you went thru all the steps, or if u just went and deleted 3 files and u were unlocked?!?!?

[Q] Bricked/dead xperia play

Here's my story:-
So I unlocked the bootloader and while rooting I bricked my play, so i got it back by installing flash tool and modding with UK generic.ftf file.
Now after using this firmware everything was fine until I clicked on software update(about phone-->softwareupdate) on mobile itself thru 3g.
So it downloaded a 51mb file and it was updating wen it swithed on, i thought thats normal but it didnt come back on for 30-40 mins and then i switched it on but nothing happened, so i took off the battery and restarted and nothing happened.
Now here's that I did and I know:-
Flashed almost 3-4 times with uk.ftf nothing....
opened the uk.ftf flashed only the loader.sin.....nothing...
flashed with the new firmware(I guess the US version with 2.3.3)....nothing...
.....My fone's start button is acting strange, wen i press that button for switching it on a green lite blinks and the fone vibrates and then again a green lite blinks but the fone wudnt start, you can keep pressing the start button on top but it wud do the same keep vibrating after every 3-4sec....nothing happens.
So I guess as I was using the UK.ftf and updated my fone here(I stay in India so obviously my fone would have had asain firmware and I was now using the uk firmware) so that mite have locked/dead/bricked my play....or is there any way out.....?
I took the fone to Sony service centre, they caught it with EMMA that this fone has a modified software and got puzzled, so i was trying to fool them until one of them called the head office and confirmed...
Any help is greatly appreciated.
----I know I can ask this somewhere else too on a diff thread----
but it dint allow me
You cant update the play via software update if you have unlocked the bootloader! It bricks the phone and as of now there is no fix, well, not that I know of!
Sent from my R800i using XDA App
There was a million warnings all over the place about this happening.
So I know of the warnings, but just forgot that I updated my play with a diff firmware, anyways this wouldnt help.
But thanks to you both for the prompt response, how abou if im sending the play to sony service centre they would charge me money for it coz its outta warranty, but they would just upload it with the asain firmware, correct?
If that happens, il try to make an dump outta it so that others cud benefit...
or maybe an asia bootloader if I cud find 1, I guess by doing so I can still get the fone to switch thru loader and then flash another ftf, sounds crazy tho..dont know yet?
There is a fix to the point of restoring it without the phone part, which sounds like it is going to get fixed soon. keep your fingers crossed. for the fix look at the other bricked threads.

Thanks for the info....hope so...but im selling off the play once its switched on lol
just bought myself samsung s2 galaxy...way fast..
Tho i had a dream for play, i finished it, sad tho for bricking it...
btw , can you point me to which thread are you referring to?
Thanks
Someone really needs to put a big fat warning at the top and bottom of those rooting/bootloader guides that doing an update after unlocking the bootloader will brick the phone.
I've put up a warning thread about that subject a few says ago in the dev section

and that's why when u bring it to the shop, ur legally an idiot who doesn't know what happened to the phone while saying..."wtf is bootloader and root? never heard..??."

Dude idiotic wud be wen u dint know anything, anyways i was trying to fool that Sony cetre guy until he called the H.O...but never mind I will be going tomm to give the device to them, tho when enquired, he just gave a statment with a hint, they will lock the bootloader>repair it(s/f etc loading)>unlock it again...
So justifying!! yes, there is way to lock it again, we just dont know it how for now.
Il try bribing him wont work but need my fone back asap.
Also, I dont now where I read or heard that if u cud change ur fone's IMEI number , one part of bootloader gets locked tho bcoz EMMA wont recognize that ....i dont know if thats possible lolz, but for the sake its illegal changing ur IMEI...I cud do that ( ireturned 2 dead on arrival plays before i got this 3rd one, mayb 3 was a bad number)
I would stick to my story and say it died when you tried an update.
Keep your

[Q] i337M Wifi/Network problems after flashing back to factory rom in ODIN

Can anyone Help me out here or try and lead me in the correct direction? So I tried to flash my Galaxy S4 i337M on BELL back to factory in odin. I used the I337MVLUAMDJ_I337MOYAAMDJ_I337MVLUAMDJ_HOME.tar.md5 But after flashing and booting up the phone Wi-Fi no longer works along with the phone either says "emergency calls only" or different SIM errors. I'm 100% sure the SIM works perfect I tested it in both or my other phones my Blackberry 9300 and my galaxy S3 and no problems. I have also downloaded that same bell rom from 3 different locations to see if rom downloaded incorrectly. The Phone is also rooted and has the philz_touch_5.18.2-jfltecan.tar.md5 recovery. Any help would be much appreciated.

cant say about the wifi issue, im having my own issues too..but download and flash the correct or compatible kernel for that rom .. that usually fixes sim errors or no signal
Do you have Knox issued in download mode? If so, you need to install 4.3 firmware only

Means you tripped knox. Warranty is now void, and knox itself cannot be used, which has some corporate implications, but if you dont use active sync then it doesn't matter. Now that youve done that, enjoy flashing whatever you want. Cf auto root will give you root, then id install clockworkmod myself via rom manager, and look for a rom to flash. If you wanna keep stock can use xposed to tweak.

so last night i flashed the bell 4.3 ROM and WiFi did start working. I do have signal however I'm still getting a unregistered Sim error. is there any kernel you would recommend? I'm willing to try anything at this point. I bought this phone and not more then a few days after getting it I screw my self out of using it.

If you flashed the stock rom, you'll already have the stock kernel. Did you perform factory resets after you flashed stock? You'll want to, i find it help. If you flashed back to odin with stock, and didn't unlock at some point, should auto assign apn, etc.
Can you confirm eimi and apn are correct? Did you clean flash? Wiping davlik, cache, and factory reset?

So guys i figured out my problem..... Which really sucks... so I bought this phone off of kijiji. the reason why my phone shows up as unrecognized sim is because apparently the phone is stolen.... after just getting off the phone with bell I found this out. so I'm out $450 bucks... I don't know if its possible but is there maybe anyway for me to revive this phone still? change the imei # maybe? idk...
You could unlock it i suppose and use on another carrier, you'd need to purchase a new sim or get one on a plan from a new carrier, unless it gets listed somehow. Not much experience with stolen handset. Maybe go back thru kijiji support and push for a refund.

I don't really wanna put anymore money into this phone if unlocking it doesn't work. and I tried to get a hold of the guy that sold the galaxy to me but no such luck. I think I just have a mini tablet on my hands? either that or a paper weight.
Sim card is like 50 bucks at most. Id unlock it (understand you'll lose LTE) and use a sim from another carrier. Can get them for travel or even online.

. I would unlock, and see if you can borrow a friends sim on a different carrier to make a few calls. If it works, try and get the new carrier to sell you a SIM. they may or may not, depends if the device comes back stolen for them too.
there are guides here you can use to unlock. Usually just a code and combination of presses to unlock. Don't need to pay for it. Search out a few guides. Isn't all that hard, and theres a few apps that do it too.

so just as you recommended I went on you tube and found a free way to unlock my phone. but even after unlocking it and using both a valid Koodo and Fido sims from my friends neither of them worked. both left with the same problem "unregistered sim / emergency calls only" So is there any real way to get my phone fixed? I dont think its possible to change the IMEI? not to imagine that its probably not legal... Any idea if I was to get a smashed s4 even if it was the i337M and say it was the US i337main motherboard would swapping it work?

i have no idea what i am doing!

hi there.
first of all couple weeks ago my phone went into a boot loop. went to phone shop and the guy fobbed me off because i didnt have insurance. so i went online to look for some help. discovered odin and used bootloader to get it out of loop. which wiped my imei number! now phone is useless, i have stalked forums and net for a while trying to get over this flashing new firm ware on my phone and trying to root it etc, but to be honest i try to follow guides but never seems to happen with me as something in the process is missing or not happening for me even with flashing the counter so i could send it to samsung( discovered i voided warranty not long after trying to DIY fix) wish i never botherd and stood my ground in phones 4 u to get them to send it away in first place!
i have gave up on me trying to do this as i dont think i have the know how to do this properly and i was wondering if theres anyone with the right knowhow here that i could send my phone to for recover the imei number so i can use it or atleast get it back to warranty worthiness as i desperately just want it working now
more than happy to cover the beer token fee ofcourse!
forgot to add i am uk based (cumbria at the moment tho i am from glasgow)
phone is a samsung s3 gt i9300
This is better suited for the Q/A section.
Uh, if your IMEI's gone then I don't think there's anything you can do to fix it... IMEI's are personal, not universal and if it's gone and you have no backup, well..... then you're SOL I'm afraid..
ahhh ok if an admin could move it to the right thread then sorry?
what does SOL mean? am sure i seen a thread where someone could change it tho?
as i said i dont know and i wish i never attempted this now.

Which version of Android were you on when bootloop occurred and which version did you flash which led to corrupted IMEI?
What IMEI do you see now?
i have no idea mate i got the phone on contract from phones 4 u (orange) 13 months ago and i am not sure what i bootloaded it with but then flashed it with the orange firm ware from sammoblie imei number was a generic iirc one cant remember what it was but i gave it to someone local to try sort the other day and now it is 355829058952634/01 when i type *#06# but on back it should be 355829/05/895263/4 as on the back. it still comes up with the screen on front with lots of yellow text(details)
Load the correct firmware with Kies. Sometimes when you load the incorrect firmware, the IMEI goes missing. It happened to me once too. Kies can revive the IMEI if it was an incorrect firmware flash.
---------- Post added at 11:14 PM ---------- Previous post was at 11:13 PM ----------
You want to find out the firmware version that was recently flashed and your phone model number which is indicated underneath the battery.
This is really ridiculous that counter boy refused to have the phone back. Though you may get solution to your phone. But you should have gone to the consumer forum for such kind of thing or share this thing on social media sites as well as the issue get highlighted and this won't happen to someone else as well.

With all do respect.... I don't think he was bashing anyone....he was just saying he flashed a ROM that wasn't posted to XDA...more than likely there wasn't any other option to ask for help elsewhere since XDA is very helpful with responses from developers and others.
I was wondering if anyone that is overseas (outside america) could share an EFI backup partition with me so I can fix my phone. Maybe that would fix.
keep watching the echorom thread someone else had the issue as well.
I cant they banned me from seeing their forum when I reported the bug.
O I see. If something gets posted that might help I'll let you know. But 1 thing I saw already is trying to flash multiple times with Odin
It might not work the first time. Or the second... or the third. Try like 10 times in the mean time until someone can help. If all else fails there has to be a way to make a working imei again since you know it anyway

It was not because of unlock. My phone was already unlocked. It happened after flashing a bad rom.

write stock rom
This happened to me before in a old Tmobile S3 (T999) I had only edge network...
It was a headache and I was only able to put it back working going to a store that had BOX for flashing and do it myself with their box
and rewrite my IMEI manually during flash, as they were not able to do it (more say didn't have patience) .
I dunno if there is a easier way to do it... but this was how I fixed mine back then. But one thing is true, I lost a lot of time back then trying to fix it and if it happens me now again I would do a quick search and if not quick solution, try to find a guy that owns a box as it will literally save you days and sleep. However there are excellent devs around so they might be able to help..

Would u have any suggestions on where I could go to fix?
Quick question. What csc is in your phone now? Have to tried changing it again with a new one or the one that was originally on it when you got it? Like a flashable zip? Cos it looks like somehow the one you used must corrupt something in the efs... which is bizzare

I went to local store that usually unlocks/fixes phones, but I had a friend connection around.. hence they allowed me to go inside and do it myself.
Try to search 1st around if there is a solution, as it might be... I can't remember how it happened to my phone, but I was flashing lots of ROM without a problem and then it happened for some reason. There is a reason for it, however I couldn't find it as my knowledge is limited. I do remember that I tried, stock, odin, kies, whatever... and nothing worked until I went to try with a BOX.
IF you can't find a quick solution try to search around physical stores that flash phones, as they usually have a BOX and probably they might pull the S7 image already for their box... try to search a friendly one and take the purchase papers with you as most are not very comfortable with anything that might involve IMEI if you odn't know anybody.

It was the German based CSC
G935FDBT1APC5
However I flashed back STOCK which has
G935FNZC1APAX
The bizzare thing is my phone appears to still get a signal, but emergency calls only. When I #06# It shows 00000000000000 for 2 MEIDs. Which is weird as I don't have a dual sim model. This is even after Odin stock, no root.

Fair enough, I still have the original purchase, I got it from overseas, receipt, and sticker still on the phone. Even the box. at the same time i was wondering if anyone overseas, (not in the usa) would be willing to backup EFS and PM me with a G935F because I could use that meid in the usa. I have no intentions of going overseas to Europe anytime soon but I might go abroad if its oceana or Asia.
