Hi Youngers!
I got a friend's Y that doesn't have any signal or service with a working SIM. It only displays an X on top of the empty signal bars. I configured it's APN, and flashed another modem , but it's still doesn't work. Any help will be appreciated.

Try some troubleshooting. Test his sim on another phone and see if it works there.
Is he on a custom rom? Creeds Rom 3.4 had a bug where you cant see the signal even though it has a signal. Can he still send messages even when signal bar is X?
Also, APN wont do anything for the signal, its only for mobile internet browsing with your carrier. Hmmm... are you talking about surfing through your carrier? or basic services like calls and texts?

Thanks for replying! It's running creed's v2. When you try to place a call it says "Mobile Network not Available". I tried his SIM card on an unlocked Atrix 4G and it made a call successfully. Texting doesn't work either. He said when he had this problem he took it to some unlock/repair shop and they failed to state what exactly was causing this.

If all else fails, go back to stock rom or try another rom
(Though I suggest latest stock rom with merruk kernel and superuser opened)

Your phone is network locked or something like that I guess.
Best way to get it solved is to post your query in this thread:

I advise to flash this pack: S5360B_UTLC2_ZTOLC_UTLC1 (open Brasil)
Flash all 3 part (PDA, MODEM, CSC)
If it does not help, then send me your bml15.img.SAVE (made by Galaxy Toolbox)
hey pal i also encountered this kind of problem before after patching Creeds ROM. What i did was I reflash the rom with stock Galaxy Y via ODIN or after the first successful boot of selected customize ROM. then you will need to apply the CSC depending on what network your country has. like mine i choose either from SMA/GLB/XTE. just dial #272* IMEI code. I hope this will help.:good:

Hi Guys,
I'm from Australia and recently bought an Optus Galaxy S4 4G. Strangely, the model number is i9507. I double-checked this online and usually weird model numbers are just carrier-spin-offs. So I went ahead to root and flash just like you would with an International i9505.
So far no problems - 4.3.x PA rom works absolutely fine.
BUT:
I've tried some Kit Kat roms recently and they all flash fine but give me 'mobile network not available'. Strangely though, I can receive calls/text and talk on the phone, but when I try to dial or send text messages, I can't do it. My reception bar is completely empty as well.
WiFi is totally fine, just no data and mobile network
I've tried messing with the 'network operators' setting and if i select my carrier (I have a Vodafone sim) I'll get network reception until I turn off the screen and then my mobile network becomes unavailable again
Not sure what the problem is; modem? APN? or roms not suitable for my phone?
Current info:

I've been flashing for a while now but it's usually just basic stuff so you can probably tell I'm pretty amateur lol.
Any help is greatly appreciated!

Hi Rich
As your baseband is quite out of sync with the firmware you are trying to run (MH2 is from 4.2.2 ,,, right?) I would suggest you change your baseband (modem) flashing an equivalent to the ROM firmware from here.
I've got yesterday the exactly same behaviour when finally and reluctantly I've added a data plan. I was running a successful low-baseband + high-firmware because was setted to "GSM Only" (try it ... will work flawless). When I've switched to LTE got what you've described in the face too . I've promptly updated my baseband and now all is fine :angel:
EDIT: please do nothing of the above described BEFORE taking a EFS backup with every tool you can find and preserving them in several highly fortified locations and 2 or 3 K7 Tapes too . Have an ODIN flashable copy of your MH2 baseband is advisable too.
Hope I've helped and please share your experience.
Nice regards.

Hey thanks for the reply! Helps heaps =)
While I still had those roms installed I did try flash a few modems within Odin, all failed though =S
Which one should I be flashing?
I believe I tried XXUFNA1 but the flash just doesn't go through
Does it make a difference which rom I flash the new modem from? I.e. flash when the new modem now or flash the new modem on the kitkat rom?
I'm currently using Pacman 4.3.1 since it's perfectly fine. Just can't wait to get on a KitKat rom though! haha

Hi Rich
Sorry, may be my fault, but quite didn't got your
You may proceed having the below as a rule of thumb:
Your baseband (modem) version should always match your ROM (firmware) version.
Failure to flash something is never good signal. As you have an i9507 (I own the 5) is very advisable to flash a modem built for your S4 flavour.
The above rule should apply to it too so, if the only modem available for the i9507 is the MH2 your firmware have to match or these issues reported will return.
Did you tested the "GSM Only" option to corroborate (or not) my hyphothesis? With this config, you should perceive no signal drops when waked. I know it isn't a viable operational mode but ... just for fun
Nice regards and keep sharing :laugh:

Hi I have international version of S5 G900F. I flashed the phone with UK BTU stock rom. Now the problem is I cannot connect to the Network.
I tried going to Settings->More Networks -> Network Operators -> Select automatically . It took 5-10 mins to search but cannot connect.
Sim is not locked as it was working before I flashed the stock rom. also I read somewhere in internet that once the phone is region unlocked, it is permanently unlocked to use any other country sim. I don't know the original region of my phone but I bought it in Uk from 3rd party dealer not from any carrier.
I can think of two thing at the moment. It should be either regional locked again, but it does not prompt any thing to activate or enter pin or anything like that. or it should be wrong modem.
Is there a way to find if the phone is region locked ?
and is there a way to find correct region of the phone ?
the label on the box was removed so I cannot find from the box as well.
Thanks in advance.
I still haven't fixed this problem. Could someone suggest how to fix?
I've attached some screenshots with my phone info.
first image shows NETWORK:UNBLOCKED and IMEI Certi: PASS
-> I think this means, the phone is not blocked by network, and IMEI certificate has passed so it's not stolen or lost claimed phone.
another screenshot is the Firmware and CSC code/country information,
-> this means, this phone is build to sell in UK, so UK sim should unlock the regional lock.
Also the phone was working fine before I installed stock rom which I dowloaded from sammobile.
in the sceenshot, one of the network is connected but it says emergency call only because it cannot register to the network.
It is not sim lock also, because when I put T-mobile sim it does not ask for pin to unlock also.
what is wrong here. any idea guys? xda supposed to be the biggest android forum and samsung s5 is one of the most popular phone at the moment, isn't there anyone who have similar problem and solved? or atleast give some reason this cannot be fixed at all.
does the TMobile sim work? does it register with the network? If yes, then call the provider (of the other sim) and ask what's going on. Maybe you have a broken sim?

I've tried with Orange sim, and it still cannot register to the network. When I put the orange sim, it pop up a dialogbox asking to choose a network provider, there was two options, T-mobile and orange. So it is detecting the sim, but it cannot register.
And also, I tried my sim in another phone, and my sim works in another phone without any problem.
Did you try to flash the firmware again, and then after that restore factory defaults?

Yes I did, still it didn't work. I emailed samsung customer service with the problem, and they asked me to restore factory defaults.
I did that again but didn't work.
I tried one custom ROM as well. same problem in that rom.
You're rooted? If yes then there might be problem with the modem part of the ROM, can you install the official one part ROM and try with that?

I've installed stock rom several times, and several different versions( from here: http://www.sammobile.com/firmwares/1/?model=SM-G900F&pcode=0 ). Rooted several times, installed modem.bin files several times from many custom rom/ stock rom. None of them worked. I tried installing modem.bin when not rooted as well. And all the attempt failed.
I did everything I could possibly think of , Then I posted the question in the forum.
You have the IMEI ??!? Or it is lost?? Then only per efs-backup…
Or sim is broken…

Sry XanoZuke, I could not do anything to fix this, so I returned the phone and got another handset. I now have Exynos Octa-core version. Found snapdragon version is more power efficient. My phone gets heated very quickly.

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.
Regarding the Exynos chip, I'm never buying anything exynos ever again. The performance is not as solid as Snapdragon and it gets heated really fast. Still, thanks for your reply! ?

Sorry i end up selling the phone as is..
Same deal
My g900f has no mobile services sims fine
I have the same problem.
Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.
Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.
I've tried *#0011# command here are results:
with LTE/WCDMA/GSM auto-connect:
imgur.com/i69HCBM
with WCDMA only:
imgur.com/QPbvKHG
and GSM only:
imgur.com/8InhQWQ
It seems that GSM is not working at all.
At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch
(sorry for messed up links but I can't post to outside sites yet)
Hi all!
1. I bought my phone (xcover 2 GT-S7710L) in the states, and when I brought it back with me to Israel, the internet doesn’t work properly. It's very slow, and shows only "G", not 3G, H or H+ like it should. Is there anything that can be done? A new modem?
2. I tried to update it do KK (from JB), and it wouldn't recognize the sim at all. Perhaps it's because I got a rom for S7710 and not S7710L (?) - do you know about a rom that supports the device? I've tried both Vanir and CM11, with no success.
Thanks! Itai
zilmsys have
Did you ever get this figured out? I'm having a similar problem with my GT-S7710L (i'm in the US) after having flashed Rom and recovery for the GT-S7710. Except I have not mobile data at all. I can still text, call, and I have wifi.
nope

The KK rom (for GT-S7710) i've flashed made the phone pretty useless - sim not working at all.. I manged to flash the JB stock rom, and it is back as it used to be - low speed internet, and a working sim card.
Hey guys,
As you can read in the tittle, my problem is that I don't have 4G/LTE I get 3G+/3G or HSPA+/HSPA.
Right I'm running Lollipop with the custom ROM, BlissPop with B14ckB1rd Kernel. I tried other ROMs (CM, RR, Paranoid) but I don't get 4G in neither of them.
I lost my 4G a quite ago, don't remember exactly how but I can imagine it was when I tried those early Lollipop builds, after that I went back to KitKat and the 4G was gone, even I tried going to full stock but neither that work.
I'm sure is a phone problem because I been with 2 different carriers and couldn't get 4G. The SIM card is brand new and today I spent around 2 hours talking with the Tech Support of my carrier checking everything is all right.
I also tried to change the Baseband/Modem/Radio (Right now I have Cloudyfa KK for the D802).
This might be also helpful for guess what could be the problem, when I dial *#*#4636#*#* go this phone information, down to prefer network type and select LTE only I lose service, by the way, in that configuration I have selected LTE/GSM/CDMA auto (PRL) and USA radio band.
I'm open for all kind of suggestions, If you need more information don't doubt in asking me.: fingers-crossed:

Could you share more information?, like when and how it happened, so we can figure out what is wrong.
Today I'm going to try to get some logs, and check the system folder.
It happened to me with stock lollipop v30d vodafone ITA with another carrier sim (TIM). Solved after flashing v30a open ITA kdz.

I'm gonna try it, will send feedback as soon as possible.
Sent from my LG-D802 using xda Forum
No luck, I installed the V30a Italian version as you suggested but as you can in the screenshots no 4G at all, when I try to force LTE (This time with the command 3845#*802#) is lose service like in my last ROM, so I'm almost sure is hardware and not software.
Can some confirm me that, cause when you go back to stock by a kdz or how ever their is not residual imformation, every thing is fully clean right? Or some firmware just stay for ever?
If you guys have more suggestions that could try before I send it to somewhere for get it repair.
Hi all! I hope you are well. I am new to the world of Samsung since I always chose Motorola, LG or Sony.
I wanted to ask you, what do I do to recover the signal from my Galaxy S8? Because I installed a Custom Rom, and it didn't raise a signal. I reinstalled the firmware (ARO), it is the one that corresponds to me, I rooted it with TWRP and Magisk, now ... I restored the backup I made with the old rom stock (the same) of EFS, which I understood, is which should have to do with the signal, IMEI, etc ... And I have no signal or data, but I see the application "My Personal" and says "Only emergency calls."
Thank you very much, any comments would be of great help and sorry for the inconvenience
I have the version of Android 9.0, it is Binary U5.
Hello, mate.
Well, i think the problem happend in just a little of us.
If you have signal of the carrier name, you need to have TOOLKID-SIM app for refresh Data Sim, the solution for me was.....
Go to Sim- toolkid>Roaming>option 1 or 2 ...
Sorry for my english.

I have tried Lineage OS 16 and Pixel Experience and nowhere can I pick up a signal, but unlike the original if it shows me "Personal" in the status bar, in the stock it says "Emergency calls only", I have the EFS folder in a backup, and in case of doubt also a Backup with the IMEI Tool application, but it didn't work for me to restore that, not even for the app. I have already run out of ideas, now I have the original one I had before with root and TWRP and I don't know what to do ?
