Help! simcards no longer work!! - Samsung Galaxy J5 Questions & Answers

Good day ladies and gents! (And those in between)
I recently installed slimstock on my j510gn. After a few restarts, my phone now needed an unlock code for my phone. Funny thing is, this phone was a glove locked phone from the philippines and im currently using a globe prepaid sim.
Does anyone have any ideas on how i could fix this ?? I really cannot afford another phone and i need to get this fixed.. Switched to viperos coz slimstock had my wifi disabled and idk what custom kernel to flash on tjis to make the wifi work.. Thanks for reading my tl;dr issue..

[Q] Network Issues

Greetings all at XDA Developers
I am having a very serious problem with my Galaxy Y. My phone keeps on going into Emergency Only mode intermittently. For example it will have signal when I go to bed and then when I wake up it will be on emergency only. It also happens randomly during the day and the only way to rectify the problem is to restart my phone.
I did have a custom ROM and that is where it started, I then installed another ROM and the same issue occurred. I then decided to flash my phone to stock firmware (it is still on a custom kernel) yet it is still happening.
If anyone could help on this problem it would be greatly appreciated.
Thanks

I thought of that as a possibility. It could be but I doubt it. The SIM is only about a year and a half old. I think it could have been some dodgy configuration with a custom ROM that is still somehow present
R u sure when you flashed stock Rom it was the version you had originally
So 2 android phones walk into a bar

[Q] Help regarding SM-G900P

Hey everyone, I been looking around the forums here and other sites and have learned a lot of info in pieces but I really need help with a particular issue. A friend of mine gave me a Sprint Galaxy SM-G900P (Galaxy S5) which is (of course) CDMA with GSM compatibility. Im unsure at the moment what service he was wanting to use but I know it is a GSM carrier (US) because he has a SIM he wanted to use. I owe him a favor so I told him I would try. Besides going the route of purchasing a unlock box and unlocking the phone with that, I discovered the SSU apk which SIM-Unlocks the phone. I downgraded the phone from Lollipop 5.0 stock to Android 4.4.2 KitKat (G900PVPU1ANE5) with ODIN. (FYI, i was stuck in download mode with no recovery mode for a week before finally getting one to work, and so happen to be that version that went through)..... I downloaded SSU and it unlocked the phone and I switched mobile network mode from CDMA to GSM Units. (NOTE: it says 4.4.2 and up will not work with USA carrier SIM cards without downgrading the Modem but I have not tried just yet) Im about to Root the phone but here is where my question comes in. I have read of people flashing roms to get their phones to work with certain carriers and other functions. Will rooting help me out at all? I guess IM asking if there is a ROM that I can flash onto the phone to enable the use of whatever carrier he is wanting to use with it. I know thats most likely useful in the situation, but Im awaiting that answer as we type. ANY help would be greatly appreciated ))) Thank you all.
Anyone? :/

[Q] GS5 KDI AU lollipop upgrade lock.

Thank you everybody in advance for the help you may provide.
Please could you help me to understand if i can fix my scl23?
This is the thing.
I got myself a KDI au gs5 scl23 with kitkat 4.4 and as i understand its rooted with a custon recovery, beacaus of the sim unlock, and the recovery its in japanese.
The phone works fine, but when i try to use it on ultra saving mode, its says that it`s samsung account isnt activated and doesnt allow me to change it(in the settings of the phone there isnt a way to change samsung account). So it bugs on that samsung account, and doesnt allow me to use internet and the keyboard when im on the ultra saving mode. By the way i live in Argentina and cant find anyone who speaks Japanese.
So, Trying to fix this samsung account problem i upgraded to lollipop 5.0, but it lock the phone and it doesnt get any antena signal, its says insert a sim, but there is no "no sim" mesage on the mesage board.
And now im dowloading the 4.4 firmaware files to downgrade it to 4.4 and to unlock it whith service menu commands.
Have anyone been able to unlock it with service menu on lollipop, or in any other way? Beacuase lollipop fixes the samsung account problem but olso locks the phone and installs custom AU rom, only in japanese or english laguage.
Thank you very much to everyone.
same here
This is the same thing that happened to me, did you manage to revert back and unlock the simlock on 5.0? Any luck upgrading to 5.0 and using your sim with the device.
cheers

Ended up downloading the 4.4 rom for phone again, installing that. Had to clear cache and do factory data clear to get phone booting again after downgrading. Then I was able to complete the Sim Unlock steps outlined here

Super frustrating using a phone like this, as it has so much bloatware from Japan which I just want to get rid of. But up and running now, with several replacement mods for keyboard, messenger etc
A lot of information out there, thank you internet and forums like this one for having so much information to get things working again. :victory:

I have an S8(G950U) which i flashed with T-mobile firmware from Sammobile.The phone worked totally fine for 7 days.I even updated the software the day i flashed the phone.Today i just woke up and i got a message on my phone saying that for security reasons your phone is locked.Now i cant even use T-mobile(Macedonia card),and not even my main operator(VIP MKD).Can someone help me what i can do? The phone is snapdragon,and the IMEI IS: 355987080853152. Its not blacklisted i did check it out.
I have 2 questions only:
