Galaxy S3 i9300 - Not registered on network - Networking

Hi at all! I'm new on this forum, so I hope I didn't break any rule. Anyway, I'm trying to recover a friend's phone, a Samsung Galaxy S3 (i9300) International Version.
He said he installed a rom called "Android Revolution HD", which appears to be an improved version of the stock rom. Anyway, now the phone does not register on the network.
The IMEI in the settings menu is correct, also the signal appears to be ok, but when I try to select a network, the phone does not register.
So, I tried almost all the solutions I have found on this site, from trying a bunch of different modems, to installing the whole stock ROM (Android 4.3).
But none of these worked. So, there is a real solution I can try?
Thanks in advance!

I have the same problem for months now i have tried a lot of solution but nothing works. i am hoping a senior member can help fix this issue. And just incase some has a viable solution, they should kindly help out. :fingers-crossed:

What I think is you've updated it from 4.1.2 without any EFS backup. Well I had been through the same situation and couldn't find I single thing. In the end I had to get my S3 repaired from a local shop. I think you should go too.

[HELP] Network problem with my I9505

Hi guys !
I've just bought a samsung galaxy s4 (i9505) (a used one not new) and i flashed Imperium v7 and modem GNF1 and bootloader GNF1 (initially the phone was on stock 4.2.2 and the problem was already there).
My problem is that i don't get the network i rarely see two or three bars but it directly goes to zero (i can see the no network sign) and stays like that until a reboot (as said it drops to no network very fast).
So my question, is it software ? (should i flash the latest samsung stock firmware ?) or is it hardware ? (replace the internal network ship ?)
Or is it a common problem on S4 i9505 and no solution cannot be found ? :crying:
Could it be related to CSC ?
Anyway, i hope anybody can help me because i really like this phone and the rom that i just installed ..
Feel free to ask me about additional informations.
EDIT : I already tried :
1) the modem+bl FNDA => same result
2) force the phone to gsm only => same result (maybe better but even it solves the problem there is no point to not having 3g activated all the time)

It's going to be pretty difficult to narrow this down with what you've posted. You say the problem was "already there" when you got the phone -- how long did you use it on the stock 4.2.2 rom before flashing a new one? Did you see exactly the same behavior before you started mucking with it?
Hi ! Finally an answer So i used it for about 3 days and i really can tell that it is the same behaviour
My fear is that it may be related to hardware .. I am gonna try to flash the latest samsung stock firmware (with its csc and modem) ?
Anyway any idea ??

In general I'd say it's worth getting the phone to "current" stock, or as close to it as possible, and seeing what kind of situation you're in (i.e. if the behavior disappears or changes in any way). If you're seeing it on every configuration, it seems reasonable to suspect that it could be a hardware issue -- especially given that you got the phone used.
Perhaps someone else knows of a more definitive test you can try.
Hey ! Thanks for the idea ! already flashed the latest samsung firmware and same problem .. i stayed in touch with the guy that sold it to me so he took it back to samsung sav where his friend (who work there) told him that this is a famous bug in the i9505 4g serie and that the only solution is a
nvm restore (something like that). Of course he'll do it for free cause we agreed that if a problem come out he'll have to solve it on his own.
Anyway, i hope to get it back tomorrow or monday ! I'll let you know what happened as soon as i get it back !
solution?
Were you able to solve the problem? in case u were, how? i have the same issue sometimes i have 3g network, then it goes to gprs then edge, sometimes when im connected to wifi i cant receive calls, but i can do calls, any idea?

No phone calls?

Hey guys, I come here very often and now I'm going to have to open this thread because I've seen absolutely no posts about my problem..
My S6 Edge+ is currently unable to make any calls and I don't know why..:crying: the strange part is that I can still send text messages and use my SIM's mobile data... Another weird thing is that whenever I reboot the phone, my WiFi passwords are forgotten..
Can any one help me? I'm currently running android 6.0.1 and I am considering downgrading it to 5.0.1 to see if it solves the issue...
Still needing help..
No one?? I really need some help since I've tried 4 different roms and modems ano nothing seems to work....
Have you wiped everything and then flashed a stock rom?

Which variant do you have and which MM firmware did you flash? Check your modem, imei, network operator etc and provide that info here.
Also wifi password IMO related with
Code:
ro.securestorage.support=true
this line in build.prop. I would suggest you to add this line under 'ADDITIONAL_BUILD_PROPERTIES' in build.prop but assume you havent rooted your device. If have, add it.

I've downgraded to 5.1.1 and it didn't work, I have the international version of the s6 edge plus and now I'm looking for a new ROM to test to see if I can solve it.. I've checked my imei in two different websites and on imei.info it comes clear, but the other site gives me a blacklisted warning, which makes me think since I bought it online second hand... it probably was reported stolen or lost and now it's blocked... which ise rather inconvenient. .
If I go to SIM Card Status it says "Not Available" everywhere, but on imei information it says my imei and on IMEISV the value is 01. It's network unlocked and right now I'm about to flash a new ROM, probably stock..
Hello, I have the same problem at boot after I receive the call when making a call nothing remains of numbering you have a solution? thank you cordially guillaume
Hi guys, I know this is a really old thread but I'm here just to say that the problem was with the IMEI, it was blacklisted..
I changed it with a friend and then everything worked fine..
Thanks for you help mates!

Password being asked after installing ROM on Samsung Galaxy Note 3

Hey everyone
I am facing a problem on my sister's Samsung Galaxy Note 3. She was facing a problem with the phone and what I did was installed a new rom on the phone. Earlier on it was Android 4.3 or 4.4.2 I think but I installed Android 5.0. I was told that the data has to remain on the device. Also the Developer option is not available. So after installing the rom when I switched on the phone, it is asking for a password whereas earlier on it used to ask for a Pin. I tried Google account password, I tried Samsung account password, I tried random passwords also like Samsung123 or [email protected] and such but nothing worked.
I tried different ROMs from different countries but to no avail. I tried installing 4.4.2 again but even that didnt help.
Any way anyone can help me with this? I am not permitted to format the device as she wants the data on the phone but then if nothing works it is the last resort and I have to do it soon as she lives in Germany and is going back in about 10 to 12 days so do also tell me if I need to take this to Samsung Service center or not.
Thanks in advance for helping.
Hi !
A good start to search is this forum https://forum.xda-developers.com/galaxy-note-3/help
Keep in mind to provide some more information in your thread like , the exact model version , ( NEO , t-mobile ...etc ) , the place where the password kicks in , the exact rom you tried to install
Now I will move your thread to the dedicated forum , let`s wait for more users with a similar device to reply , thank you !
Good luck !

SM-T355Y random reboot

Hello everyone! My relatives from india recently gave me a galaxy tab at SM-T355Y. Unfortunately, since updating to android 6, it has often begun to restart uncodedly. I've already tried to do a factory reset, without success. By chance do you know how to help me? Can I try some rom? Is compatible with rom t355? I am Italian and unfortunately in this version of firmware there is no Italian language. Thanks for the attention. The tablet as it is can not be used. I am open to every action. Thank you all.
Restart is not related to OS, this LTE version has the same problem as Wifi one due to loose battery cables. However, it's an easy fix by silver conductive glue
I already posted the solution in this forum

S8 plus ussd problems, call forwarding

Hi first post here but not a complete newbie. But this time I'm stuck big time and would appreciate some help.
I've got a s8 plus that recently started playing up. All of a sudden it started not being able to make or receive calls. But I noticed it only happened when the "conditional call forwarding active" message didn't appear when dialing. I figured it had something to do with call forwarding so try to change the settings on supplementary services settings but when I tried to enter the settings an error message appeared "failed to read data" I tried sending the code manually to cancel voice mail *#022# to see if it would work but I got "connection problem or invalid mmi code" so assumed it could be that the phone is trying to check with the network the forwarding settings as the call starts but for some reason it cannot communicate with it as the mmi codes don't seem to working?? (I'm not that knowledgeable in that area) I tried all the fixes online for the "connection problem or invalid mmi" but none work so I flashed the firmware through Odin even tried a few different ones, I've been playing around with Odin for a while so I'm comfortable with it, I even flashed a pit once for a note 4 that was bricked (just saying so you can see I'm comfortable with using it, not an expert just comfortable) but nothing has fixed my problem my phone is a g955fd running pie and one UI with the latest security update. I've read the duos have some issues with this. I've tried other sim cards on my phone from different carriers and the problem is the same and I'm using my sim on a borrowed phone and no problems. I'm assuming the problem goes deeper than the firmware, could this problem be boot loader related? Would a nand erase and reinstalling the boot loader fix it? Everything else works 100%
Someone please help me, the phone I'm borrowing is an apple and every day I have it I feel weaker and dumber, it's like kryptonite.
Sorry for the long post but I've been browsing xda forums for years and I know that you guys always say to share as much info as possible. By the way I've searched and couldn't find a thread about this but it there is one I promptly apologize and just ask for the link to it if not thanks in advanced.
? G935F or G935U exynos vs snapdragon
Way for snapdragon
Flash https://forum.xda-developers.com/galaxy-s8+/development/rom-t3901074 with odin and test with hard factory reset recoery.
After, flash odin last firmware stock sammobile
Thanks
Thanks for your reply deadedge7
As I said my s8 + is a duos g955fd variant and has an Exynos processor, I'm not sure that rooting it would make much of a difference, as to my understanding rooting doesn't really change the boot loader it just allows you to install a custom recovery and roms. Which is not much different to reflashing a stock rom for all intents and purposes , but I might give it a try anyway. I guess that maybe a rom like the one in the thread you shared might give me some more hidden codes access as a root but I'm not sure. I will try to find a root like it for my variant unless you know of one and can point me to it.
Thanks
Hard reset or flash stock software or hardware problem
For iemi best way is root efs with flash twrp best way for /EFS

No solution so far. I've rooted the phone and install a couple of custom ROMs but still nothing. I'll try and roll back the firmware and see what happens. I'm no expert but I still think it is fixable. If I find a solution I'll post it on this thread. If you find one please share. My solution at the moment is getting a galaxy A50, very comparable performance with the S8 and really cheap.

I'll keep that in mind. Couple of things to note: I don't get the message conditional call forwarding active. I don't think I ever have.
I tried a different carrier SIM card(T-mobile) and it worked (I'm on At&t). I was able to make and receive calls. Even tried an out of country SIM card and received calls. But my At&t SIM works on other phones perfectly. Go figure lol.
The only other reason I can think of is maybe cos it fell a couple of times from the couch. About 1.5ft. New case kept making it slide off.
