Samsung S7 Edge: A brick or a solution? - Android Q&A, Help & Troubleshooting

I purchased a 2nd hand Galaxy S7 Edge from someone on Facebook Marketplace. It's a dual sim model (which is not directly available in South Africa) - When I collected the phone the old owner manually removed apps which I found to be strange as I was planning on doing a factory reset anyways, but he said I first had to update the phone before I can do a reset. Once I got back home and put the phone of WIFI > Software update I got a message saying that the software was not verified (leaning towards the phone being rooted). I also saw that he had multiple copies of Whatsapp which I knew was not possible with a normal ROM.
Not wanting to constantly see his personal info, I decided to reinstall the base S7 Edge software I found sammobile.com - Using odin this worked and I was able to reset the phone, but now there is no network coverage at all. I have tried everything, even downloaded a different version (both XDA and XDE) but no luck. I took it to a cellphone shop and they say they think the moterhboard is faulty which I doubt, when I got the phone and put in my simcard the first time around there was no network issue at all, this only started once I reinstalled the original rom from Samsung.
My understanding now is that the phone was likely purchased in UAE or Dubai and the network was unlocked (not sure how this works) - When I reinstalled the default samsung rom the network lock is back and I can now not use the mobile device with my local provider.
What options do I have? Is there another rom (even if it's not samsung, happy with anything) I can use on the device? I presume they had a different rom installed anyways to get it working in the first place, but I was stupid and never made a backup of the rom so now the phone is nothing more than a wifi device.
Any assistane would greatly be appreciated!

[Q] can't call

hi there!
Ive read all I could and despite coming across several similar problems, haven't found an answer (so if anyone has an idea, plz help!)
I'll try to be as concise as possible:
I have a message that says: not registered on network
I have a China Unicom galaxy S3 (international model, gt-i9300) not copy, original version, bought from service provider store, running forever on android 4.0.4 (no updates available, via kies, or software update whatsoever)
As you know, because it was bought in China, it's blocked from factory settings (no svoice, google play, among others and of course a reduced overall functionality and an alarmingly high used of RAM despite of every app being closed) and even you can download most apps, they're in Chinese and they're different and not completely working versions of them (i.e. fb, skype,...)
Read and read, until managed to do rooting via heimdall (only have mac available), once installed SU, managed to download and install google play, but it kept on crashing, along a previously (VPN only) functioning fb app, and twitter.
After a while of more research I came across odin mobile, and by downloading an international ROM from Hong Kong via Sammobile, managed to install 4.1.2 from HK (I9300OZSEMC1). Despite the now no restriction phone i had, i came across a problem: cannot call or message or use mobile data, only with a message that says " not registered on network"
I did check the sim card, and selected the network manually, without success.
I checked the AP, CP and CSC and they were unknown.
After much frustration i remember i had a backup if the original carrier, and after re-rooting, managed to get back to the super blocked version of it, bu t the problem remained: not registered on network.
I checked again the ap, cs and csc and now are back to factory default (just like they were before all this odyssey began).
I changed the sim card to my gf's iphone and it works there, just not on the galaxy....
I repeated the above two times more, using roms from HK, Taiwan and UK..... same problem, even when going back.
Any ideas? I'm quite desperate now
thanks!!!
Is your IMEI the same as under the battery .
If not restore your backed up EFS folder.
No backup = service centre .
Do you have the correct modem and CSC for your network .

yes, imei is the same
before doing all the process, i verified and saved screen captures of how it was before and after, both pictures coincide, but still nothing...
(what is EFS folder? , i've done this with little knowledge on the topic, so i've no idea what's that ^^"
I guess service centre might help, but well, since this is China... i expect the worst.

I'm assuming you may have changed the modem during the flashing of the HK fw, try finding a Chinese Modem and flashing that. TBH this is why people tell you to read and read again before rooting and flashing custom roms.

[Q] Is my phone software unlocked(versus factory) Please helpp?

Hello,
I will have to give background info on this before anyone can help so bear with me please :.
I live in Pakistan and I bought a i9300 directly from samsung. In the beginning of the six months i owned the phone, I never rooted or put custom ROMs on it. Then unfortunately I got SDS. I gave my phone to a local repair shop (non samsung, but highly reliable, I bought the phone from there) who switched the motherboard on the phone. After I got it, I rooted it and started installing custom ROMs on it. First it was cyanogenMod, then Paranoid Android and Supernexus +AOKP and others. Everything worked fine. Then I installed Omega ROM (Samsung based ROM which changes the modem). Everything went fine, but I was unable to connect to my network (No texts, calls, data connectivity). It detected my network(Ufone) but was unable to register on it when I manually tried to. I mega-wiped my phone, cleared cache and factory reset and did everything. Alternatively, the following steps I also tried.
1)Checked if my IMEI is intact. It was. (I have EFS backups too)
2)Checked if my serial # is different. It is still the same (No need for Ariza Patch)
3)Checked if my SIM works. It does on different phones.
4)Checked my APN settings. They were fine. I even manually changed them to match the carriers
5)Changed my CSC settings (using the playstore app). Still doesnt work.
6)Checked different modems from the appropiate thread (I have tried Europe Unbranded, Middle East, Egypt and many others)
7)Restored nandroid backup of original stock 4.1.2 Sammy ROM, still not connectivity.
8)Flashed using ODIN, the stock 4.1.2 ROM for my country (Using SAM mobile). Still no connectivity.
9) Matched my RIL with my baseband (using the GetRIL app), still didnt work.
Stock Samsung 4.1.2 ROM details before OMEGA flash in which everything worked:
AP: I9300XXEMA2
CP: I9300XXELLA
CSC: I9300OJVEMA1
This has happened to me the 5th time now (Phone is currently at the repair shop) and I have sequentially tried every one of the steps I have mentioned. I called up the repair shop and they said that I can come tomorrow and pick it up, all they have left to do is "SIM UNLOCK "the phone. That confused me a lot. I will go tomorrow and ask them details as to what they meant by that. So my question is basically this:
1) Is it possible that the motherboard they put into my phone is from a software-unlocked phone not a hardware unlocked? (Is the 'unlock' on the motherboard of the phone)
2) Is there a way to find out if my phone is software or factory unlocked?
P.S. Every single time I hand in my phone, I obviously unroot it and install stock on it (regardless of the fact that it doesnt connect to the network). But every single time I get my phone back, its ALWAYS ROOTED.. I even asked the technical team guy and he had no idea what I was talking about (repairmen here dont have that much of knowledge, they tend to follow guides online, thats it). So could it be that my connectivity issue is just because its software unlocked and not hardware?
Thank you!
Anyone?

Not a genuine service centre then .
IMEI
MODEM
CSC
all correct for network suggests a hardware fault .

But it's not a hardware fault? I mean whatever they do, they have to root the phone to be able to do it. Any idea what settings or configuration they might have changed using root for it to connect which I haven't already tried?

Investigating repair of Emergency Only issue on Galaxy S6 Edge

Hi all!
I bought an S6 Edge second hand and after flashing a stock ROM, I had the "emergency only" calls issue, I tried everything I could find in the forums to no avail and I ended up taking it to a repair service. I did not think they could fix it but they did and I would like to know what they did to it in order to prevent it from happening again and to know if I can leave it as default (not custom OS) so that it can upgrade.
State of phone when bought:
So, the phone was working well with all carriers (from Colombia). The only thing I was able to notice after I bought it was that it was still on Marshmallow (6.0.1) with carrier branded stuff. It was in perfect shape otherwise.
So I downloaded a stock ROM and installed it using Odin. After this the phone would not let me make calls as it was not registering on the network. It did not even let me make emergency calls despite getting full bars of signal and being able to recognise the list of carriers when attempting to manually connect to them.
Important: The ROM downloaded was for the right version of the phone which was the G925i and the IMEI, serial number and baseband were not altered from the original. Also, I checked the phone to see if it was reported as lost/stolen and it was not (of this I'm sure because in Colombia you can consult a centralised database on any carrier's webpage). Also.. Here in Colombia it is illegal for carriers to lock phones.
Steps I took to fix it:
Downloaded ROMs for all carriers, branded and unbranded, I even installed one from Trinidad and Tobago and a LATAM one.
I performed all the tricks to disable and enable flight mode, location services, try con connect manually to the networks, changing to GSM only, GMS/CDMA, international roaming, etc.
I also extracted modem.bin from an earlier version and flashed the modem.bin with Odin (6.0.1 moden on 7.0, 5.1.1 moden on 6.0.1 and 5.1.1 moden on 7.0). All modems flashed correctly and the issue remained exactly the same.
So I finally gave up.. I installed the latest stock ROM which was an unbranded Nougat (7.0) version and took it to a repair service and they fixed it in a couple hours.
What I noticed after the phone was "repaired":
- The phone was rooted, SuperSu was installed, no other root app was installed.
- On SuperSu, there are entries for ADB shell (they all say Superuser command contents have not been logged for this entry) in a two minute timespan.
- The android version was downgraded to 6.0.1, I was told not to try to update it.
- Developer options was enabled with USB debugging turned on.
- The boot option (the one where you can wipe data and cache partition) was left as original (not the TWRP one).
- The ROM used to downgrade was the same I had before but only downgraded the version.
I suspect this same procedure was performed before on the phone but it had the original ROM carrier branded so it seems as if they installed a custom ROM, rooted it, connected with pc and performed some command line stuff to fix it, then cleaned the bootloader to a stock one.
The questions:
Any ideas what did the repairman do to fix the phone? Also, would it be safe to make a full backup with TWRP and flash again a stock ROM upgraded to 7.0 and then flash the backed up modem to get it working? Or would that possibly screw up the repair?
Thank you all in advance for any help. I'm sure there are lots of people out there experiencing the same "emergency only" issue I had but there does not seem to be a fix around, but clearly there is one! So I hope this sheds some light into what could possibly happen.

Sm-g925f model wont accept any other stock firmware except sc-04g

I have been at this issue since Saturday and gone through a lot of possible solutions but to no avail. So first of all i am in Ghana. A friend came to me with his s6 edge that he had some issues with his phone going off when he unplugs the charger and getting stuck in a bootloop when turning it on unless he plugs a charger in before it boots up fully(even with full charge)
So first of all he wanted to do a factory reset(phone was not rooted). Factory reset completed successfully but issue still persisted.
Specs of the phone was:
android 5.0.2
model number = SM-G925F
original csc (i wasnt able to note that down because downloading stock firmware was going to be the last ultimate weapon. first i was going to try some custom roms to see if it fixed the issue. Besides it was working fine here in Ghana.)
So that's when i flashed a twrp and i dont exactly remember but i think i might have tried to flash a lineage OS or something. But long story short, when u try booting up, the samsung galaxy edge screen with powered by android came on and stayed there. and it did not go on to boot up.
After trying through the night i then decided to use the ultimate tool and flash a stock firmware. Try as i might none of them got past the "Repartition Operation Failed" portion of flashing it. The Pit File was becoming an issue. Tried firmwares for my country, countries nearer to us, contries in africa and finally even european firmwares. And since from reading from here and other forums that the F variant was an international version the international pit files should work but they werent.
All this while whenever i go to Odin Download mode on the phone, the product name there was SM-G925D. This started the confusion because at that point i had looked through alot of firmware and that was not an option. When i searched google for that, the search results mostly correlated it to SC-04G, which looking at it was a Japanese firmware. I didnt want to use a japanese Firmware for obvious reasons. At least i wanted a firmware that was by default in English. But after about 2 days and seeing a lot of answers saying stuff about going to settings and checking stuff there plus me wanting to see an interface and work my way from there i succumbed.
And lo and behold, it flashed on the first try(i used the 4-part files firmware. It was android 7.0). But when it came to booting up, the splash screen had changed from samsung bla bla bla powered by android to NTT DOCOMO powered by android. But it booted up and i skipped through the setup. i had to change the language to english but there were a lot of japanese bloatware that came with it. But as i expected when i popped a sim card into it, and restarted the phone, there was the not available symbol(circle with a bar across) where the network bars were supposed to be.
Seeing that this was not going to do, i went to the settings this time to check on any important details and this were the new details
android version 7.0(January, 2018)
model number=SC-04G
build number was now SC0.....(cant write the full code as im currently in odin mode)
But obviously it was the japanese network. After this i have downloaded more firmwares and they all fail at "Setting PIT...Re-Partition failed". Somtimes i try to mix the 4 files up using maybe the CSC portion of the Japanese firmware but BL, CP, and AP of firmware from my region. This time the error is "sboot.bin failed".
And that has been my grind till now. Downloading likely firmwares and all failing to doing extremes like the mix and match. When the mix and match with BL, CP, and CSC of Japanese with AP of my region works and eventually boots up, there is no touch input. The touch does not work. When that happens i just have to start all over with the SC-04G, which never fails to work.
I have even seen some things about changing csc files in the file explorer with root so i flashed the Japanese FW and rooted it. Went through the processes but to no avail.
PS:
The first part of the Odin screen where you choose to continue or reboot is now completely in Japanese whiles it was formerly in English.
And there is no indication on the phone itself that it was from Japan. The back says Samsung and below it says Galaxy s6 edge. Friend bought it from a shop in Ghana here brand new.(not from a carrier)
****So here lies my confusion. How come a phone with an original model number of SM-G925F have a Product name of SM-G925D in Odin and hence only Flash Japanese Firmware SC-04G(CSC code = DCM) but would not flash any of the international variants. Even if i can eventually get the Japanese firmware to read the sim card we can manage it that way. But thats for when there are no options left.
So please i would like to know your ideas as to how this is happening and any possible solutions that might be different from what my batallion of open tabs are telling me. You can also let me know if you want any more details i might not have included. Looking forward to hearing from you guys.
Update On Issue
I ended up using the japanese firmware in the end because it wasnt picking anything else.
This time after the setup process, it picked up the sim card and the imei is available. So since network is now available i just rooted it with cf autoroot and removed the japanese bloatware and everything looks normal now.
Except the original issue of going off randomly whn power cable is pulled out even when having full charge.
:good:

Samsung Galaxy A50 -Software Update Issue after unlocking phone and switching network

Hi,
So yesterday I successfully unlocked my Galaxy A50 from Three network and ported my number to 48 network. Went to a phone fix shop to get the phone unlocked and it took about 20 minutes (cost me €25). Everything about the phone and 48 network works fine. However, when I went into Software update in my settings and tried to download and install the latest software update, I receive the message "Your current software version isn't supported. Visit a service centre".
I never had issues with updating software before and after checking online it seems that maybe the software updates are carrier locked (to Three network) and that if I want to update the software I would need to put an active Three SIM into the phone.
I rang back the guy who unlocked the phone and he said that people never come back to him with this issue after unlocking their phones, but if I wanted he would be able to manually update the phone and in the future it should update automatically, but this will cost €35 as he said he may need to backup everything and upload it again and it's a lengthy process.
It's either that, or find a Samsung Service Centre in Ireland (can't find any on website) or put a Three network SIM in any time I want to update.
Does anyone have any experience with this? Would really appreciate some help!
