someone save me please... I've been struggle for two weeks...
I'm using S5-G900F, its a Hongkong version, and I'm currently in UK with giffgaff. last month I tried few new rom and then I can't use voice service any more. However I still have internet. Some detail below:
APN
1. I 100% sure its not an APN problem
IMEI
1. IMEI seems ok, start 4 digit 3524****
SIM card related
1. At first I assume it's a SIM card related problem, I tried 2 SIM with different ISP, neither work.
2. Also, I put those 2 SIM on my iphone4 to verify that the SIM is good, and both card work.
3. I also checked the SIM card cable, I put one piece of paper above the SIM to tight the contact, still doesn't work.
Phone related
1. Before I brought the phone, I had check the bands it supports, and it is capable to used here. And the phone work perfect (well, with stock firmware its really slow) before everything happen.
2. Since I brought this phone in HK and now I'm in UK, I tried to flash both latest UK and HK firmware (lollipop), neither work.
3. I also tried only flash baseband from that two firmware plus one old-version baseband. none work.
4. For those flash mentioned above, I do full wipe.
Rom
The rom I tried list below (in time sequence)
1. XtreStoLite (the BL/baseband is extract from Brazil stock firmware. After that problem occur, but I didn't realize)
2. CM12 (this two are all from this forum)
3. TGY-G900FZHU1BOA1-20150120092320 (HK stock firmware, 5.0. Try to recovery the voice)
4. BTU-G900FXXU1BOB7-20150223084756 (UK stock firmware, 5.0. Still trying)
5. Also 2 baseband/BL from XtreStoLite thread (Another is an old-version. Still).
So now for everyday, I had to carry two phone... one just to make sure I don miss any call.... I have tried and still no clue... really need some help here.... Help please...

Can anyone help me please....
Was the phone service working for you before you tried a new ROM?
I have the same issue. Can't make or recieve calls. Internet is working though.
When you try to call someone, do you get 'call ended' message almost immediately after dialing out?
Also, when you go to phone / settings / additional settings (or more settings) - does the 'network or sim card error' pop up?
Can't figure this out... Hopefully someone would be able to point us to right direction, other than to replace it
And of course I did a factory reset, new roms, modems, everything there is to try. nothing helped
could it be because of Region Locking? Maybe it's locked again after flashing?. I want to buy this phone but I am not sure if it will get region locked again after it gets updated or custom flashed.

Yes, before I flash those ROM everything goes well. I'm currently using CM12 so I don't have the setting you mention. But anyway I never seen that pop message before. I guess the SIM card work good as the phone can connect to the internet (not wifi, cellular internet).
Hi
Last june I finally got my new Redmi 2 Pro (HM2014819, ergo the Brazilian version) and as soon as it arrived, I decided to reflash it into the latest available Nexus Experience custom ROM. Before that, though, I managed to check that my phone did had access even to LTE networks.
Turns out the GPS got weird because I supposedly didn't attempt to fix it before in the original ROM. I tried the the modemst1/2 format trick and it also didn't work. So I flashed MIUI7 over it again in an attempt to get a fix in the original ROM.
When I got back to MIUI, all celular/signal data was gone, along with my IMEI number (probably from the modemst partition wipe). I had to struggle a lot and I finally was able to recover it using this tutorial. However, as I just noticed recently playing Pokemon Go, 4G networks never came back even though I'm up and running on both H and H+ networks.
Using QPST and QXDM, I delve further into the QCN file and I could notice that the LTE values were actually set for Redmi2 PRIME version, which are Asia-related basebands 3 and 40 (meaning the actual LTE value in binary had 1's in the 3th and 40th bytes). However, the Redmi2 PRO version supports South America-related LTE bands 2, 4 and 7, as GSMArena points out.
Using this information and following this guide, I also tried to change/write over new Decimal values that would match my required LTE bands, but to no avail. When manually selecting networks, only 3G networks show up, even though I'm sure I could see and even pick 4G networks manually when I first booted up my (at that time, unmodified) new Redmi2.
What did just happen? What CAN I do?! How can I recover the intended, factory original version of the brazilian Redmi 2 networks?! Is there something to do with modemst2 erasure, or IMEI loss, or even NON-HLOS.bin file? Aren't they all overwritten when you reflash MIUI through MiFlash anyway?
Please, PLEASE, help me! I'm already on the brink of purchasing another cellphone (and it won't be another Xiaomi, that's for sure) if I can't get this to work. I did purchase this sorely because of the 4G connection and now I lost it entirely. Come on! :crying:
damn.... i've done this mess of erasing modemst's too and got the same problem. VERY LUCKY of me, i had a twrp backup that i did some days before doing this. hope you find some solution to this and dont give up on xiaomi just for a mess that you did xD

Igor, do you think you could at least share your modemst partition and/or your QCN file? I could use this to find the differences between my modem configurations and set it exactly as the brazilian's factory default modem.
If you're worried about IMEI scamming, then a simple printscreen from certain screens on QPST/QXDM will suffice, since I can tell what's wrong from them. If you're willing to help me (and have a rooted device), please, do tell and I can walk you through how to get them. Thanks!

Follow this tutorial.
My signal came back but I'm having frequent signal loss. The only solution is to turn on/off airplaine mode.
I've to send it to tecnical assistant but I don't want to stay without the phone.
Acttually I'm not sure if the 4g works, because my city only supports 3G. When the data connection is on I don't loss the signal.

That's the exact tutorial I've followed to recover my IMEI. And I even mentioned that in the OP, bud. My problem happened after that. Please read more carefully.
Sorry, I just saw the second link.

Oh gosh guys, I hope you can help me too! I've got the exact same problem with my HM2014819!
Did you manage to fix that?
Hi the exact same thing happened to me, I had no mobile internet at all and I fixed that qcn stuff but all I could find was asian versions, I get no 4G network and I have no other brazilian file to compare. If you managed to fix that, please please share, thanks a lot.
I've had a few mobile data related issues on a few different ROMs now, and am looking for any solutions. The first problem I've been having recently is where my phone randomly reports that there is no SIM card inserted and won't make or receive calls and cellular data doesn't work. Simply rebooting or removing and re-inserting the SIM will instantly fix the issue but I'd prefer to find a solution so I don't have to reboot my phone all the time. Another new issue I've noticed is where the signal strength remains constant but the "ASU" goes from 40 or so to 99 and my bars appear to drop to nothing, this issue may have only started after my most recent install of lineage. I have the US variant of the phone and currently have Lineage OS 14.1 but even when previously on an unmodified copy of EUI 21s, albeit after installed after a few other ROMs, I was getting this issue. Does anyone have any ideas why I might be having these issues, or any ideas on what to try to fix them? Any insight is appreciated!
in my case I have the x722 and this does not recognize any SIM at any time
Did you try factory resetting? Are your APN settings for your carrier correct? It could be a lot of things. If you bought it in the U.S. from a U.S. store, you'll probably be able to RMA it (easier than the rest of us, at least). If the issue persists, I'd say open a case and ask for a replacement because it's your best option.
When did these issues start? From the beginning? If not, did you flash the modem correctly?

I don't remember exactly when I started having these problems to be completely honest, I just know that on EUI, after once flashing to lineage then back to EUI, I was having issues with it saying NO SIM INSERTED and now after flashing to Lineage and re flashing the 19s modem I am still having issues. I suppose I can try to RMA since I bought it at launch on LeEco's US store. Though I may have passed a year of ownership so I may be out of warranty . I don't really know what else to try, maybe this?
My understanding of this phone is, flashing stock rom (either US version or CN version), whose size is about 1.4g bytes, can give you the modem.
All the roms developed here do not have modem images.
I have faced the same issue trying installing custom ROM while sim card inserted.
The solution for me is to remove the sim try completely
Fastboot this (chinese stock) rom : https://drive.google.com/uc?id=0By_Lx-WrwGa7cnZMZWF4QUdmQm8&export=download
complete the installation normally using your wifi and then insert sim tray with sim. Hurray ! I got that working.
With this chinese stock rom I got everything what I wanted google play store, assistant and etc. (except android > 6)

First thing don't flash this ROM is not a good idea bad advice.
Try flashing 727 19s modern backup all on computer and do a hard reset.
Let know if this helps?

Haven't tried 727 19s modem backup, but what works for me is this ROM.
I know this ROM is in chinese and you might struggle on changing the stuff but when I faced the issue, the only thing I needed is to make the device usable whatever it'll cost.
It'll be great if modem backup thing will work for anybody. This ROM might be the last option for you.

If you flashing that ROM with their firmware if you have a big problem you can't fix it you are bricked 727 pro users should flash that firmware ect!
Their averaging one brick a day flash your own firmware stay safe.

Hey guys, i was wondering if i can flash firmware from other carrier without bricking?
I bought my phone last year locked to carrier, and I unlocked it using doctorSIM service. Phone itself works fine, and as I'm not living in country that i bought my phone from originally, phone gives a message "No SIM card installed" sometimes once a week, sometimes several times a day and i need to remove SIM card or to restart phone to make SIM card work again.
Please note:
- SIM Card from my original carrier (from one that I bought my phone from) works PERFECTLY fine
- My other SIM card (that my phone constantly rejects) works in other phones just fine
- I have tried to reset the phone, and carrier bloatware constantly keeps installing
- EDIT: Wi-Fi and 4G are working PERFECTLY fine
What to do? Any ideas?
Thanks in advance and sorry for gramar mistakes
Bump, flashed other carrier firmware, still same problem.
R u rooted? Have you considered flashing a CSC packet for your location?
I have a 930S, and works fine with the Korean ROM/Chinese language here in the US, on ATT service.
I have flashed the ATT, XAA and TMB CSC sets, and though the phone worked, and loaded the correct USA carrier info, I lost the phone code ability, which I could not solve.
In the end I went back to the original Korean ROM and it's CSC packet. Interestingly, though it works perfectly here in the U.S., and I can use/input phone codes, it still shows Chinese cities for my 'Region", none of which I have selected. When I do a search for local towers, it locates and correctly identifies AT&T, T-Mobile, etc. I select ATT. The Chinese cities remain in the region selection, none selected.
Wait and see if someone knows if CSC (Exynos or US based CPU) are interchangeable. I used CSC packets from a universal ROM setup (non-USA).

I'm not rooted, as I use Samsung Pay and have more than one year of warranty left. I will try flashing CSC of the current country I'm in (Austria). Thanks for taking time and writing all this, this problem is unbearable
Hello!
My s7 edge is in trouble, it freezes sometimes, and sometimes it gets a full screen of pixel color flaws, with that problem my root smartphone works two weeks. Sometimes this error occurs in the ROM installation process, I insist on the installation until I can. I tried to install superman rom and due to this problem, the smartphone in the screen of death "exception of bootloader" (But it's already been resolved)...
When searching the internet, I saw that this could have a problem in flash memory.
After all history, I ask;
I could use a twrp file system repair function to try to solve this problem? And how to proceed?
(sorry for the use of google translate)

I am, by far, not educated up on TWRP, so I'm not sure what you mean by "repair", other than making sure your data partition is formatted so it does not cause the issues you are talking about.
Here is an interesting read:

Hey guys, update on the problem, i replaced sim card and it works just fine, i will post updates as time goes on
Thanks for the help!
Hey guys, I flashed a JUI ROM, and it flashed something to my EFS partition that is forcing my device to reflect the CoolPad S1 LTE bands (which unfortunately doesn't support any USA LTE for my carrier.). Immediately restoring my backup didn't work because it failed to decrypt my Internal Storage (meaning I had to wipe device.)
I've been unable to get the LTE bands back. Does anyone know what I can try? I've tried the below items.
* Tried manually enabling bands via QPST or Qualcomm Tools. The bands show up in certain apps, but device does not connect to them.
* Completely wiping and restoring device via QFIL restore by Tora33. Still seeing no LTE.
* Flashing USA 21s latest stock ROM w/ 5.8.19s modem. No go here.
* Reflash do manually all of the 5.9.23s firmware (w/ USA modem), no go.
I do not have an old EFS backup which I think is what I am in need of. But I think it's device specific...if anyone has any ideas, please let me know. I am missing this device since I need LTE for coverage.

Yes, there is a TWRP recovery here on XDA that is a full unencrypted backup of 5.8.19s you could flash it to restore your bands.
I do not have the link at the moment. But I will post later today or you could search for it, it may be easy to find with a simple search for TWRP 5.8.19s recovery.

Hey, unfortunately I found the link and it did not work after restoring this. I do not know what JUI did, but it really did not play well with USA Le Pro3.
I just tried this and no go either.
https://forum.xda-developers.com/le...lock-bands-leeco-le-max-2-fix-t3439154/page25
I think we are SOL, unless a dev can chime in that understands how the modem is programmed.
EDIT: After trying this guide https://forum.xda-developers.com/le...lock-bands-leeco-le-max-2-fix-t3439154/page25, I was able to get LTE back after flashing AICP after enabling the bands in the link. I am so happy! I'm going to see if reflashing EUI restores bands. If not, I'll just stay on AOSP ROMs lol.
EDIT2: EUI has LTE again.
Glad to hear things worked out, I had a very similar problem a while ago but I believe I ended up having to unbrick my phone(using some completely Chinese Le Eco recovery tool). Then by going back to EUI 18s and 19s I had the ability to connect to LTE. However, the problems I started having was LTE dropping in and out, and on EUI getting a random SIM NOT INSERTED error requiring a reboot/restart. It actually doesn't drop or slow down on Lineage while using data, only when my phone isn't actively using data, i.e. android auto/sitting on homescreen . Anyway, I'm just hoping you can give me the link to the flashable 19s so I can quickly try that, also let me know if you experience this intermittent LTE drop thing, thanks!
