Mobile network not available

Hey, last night I managed to install cyanogenmod 7.1 on my GT-I9000M. The purpose of this was to root the phone, so that I could SIM unlock it. I ran the free unlocker app by helroz, and it didn't make any complaints, so assume it worked.
As you'd know, the GT-I9000M variant is from Canada, but I live in Australia (Bought it off a friend). I tried putting my SIM card into it, and it does tell me my carrier (Telstra), but the reception bars remain greyed out, with a little x up the top.
When I try make voice calls, it says "Mobile network not available".
Does this mean the phone is still SIM locked, or could I be doing something else wrong? Is there a way to check if it's still SIM locked?
I have taken a few screenshots that may help:

You need to flash KG3 modem.
Here's the link to the post by [Ramad] with modem for i9000m.

Hi, thanks for the reply
I'm trying to do that now, through Odin. I put the .tar.md5 file into Phone, and went to flash it, but it failed. It seems odd that the file has 2 extensions, is there something i need to do to it first? (Most modem files I've seen have been .bin files?)
EDIT: Nevermind, managed to get it to flash. However, now the phone won't pick up my carrier at all, and baseband version is Unknown?
Regards,
Dan

Maybe try to flash it in recovery mode?
Here's one for CWM.
View attachment Modem_KG3.zip

*ignore this post*

Bell i9000m by default is 850 or 1900mhz , try to change it to 900 or 1800.
Dial *#2263# and in GSM menu choose either of em.

Dialing *#2263# doesn't seem to do anything
I've installed the new modem you linked me, it still says "Telstra", however still no reception apparently (I know I do get reception in this room, and the baseband version seems to be the same)

Same thing happened to me I had used the wrong version of cwm to install the rom. All I did is reinstall with the cwm that the rom had installed itself and everything worked fine .
Sent from my GT-I9000 using XDA Premium App

I just tried reinstalling cyanogenmod from it's own CWM, but still have the same issue.
Just looking at the phone now, it seems the signal strength is always on -111dBm and 1asu, doesn't change.

Sorry the sane fix didnt work for you .I moved to darkysrom myself because of so many missing features in cyanogennod like the tv out feature.
Sent from my GT-I9000 using XDA Premium App

Yea, I'm wondering whether the radio hardware itself might be broken. It always shows no service with this SIM, no matter which modem version I use, which firmware etc. Signal strength always shows -111dBm 1asu and that's about it.

Flash a GB firmware with pit and repartition, I think that you need to do that when flashing back from CM firmwares, then see if the device functions properly.
Check if the IMEI-number is not changed, if it's not changed and the device still can't detect the SIM-card then try executing on Terminal Manager (from Market) or using ADB (su and busybox must be installed on your device):
su
busybox chown 1001:1001 /efs/nv_data.bin
reboot

If the device detects the SIM-card but the device gets no reception then flash a modem that supports a different band, UGKG3 for I9000M supports 850MHz and the modems for I9000 supports 900MHz out of the box.
The idea is to try to narrow the problem down to 1 point, you need to know which modem you need and you also need to know that your device is not defect, doing that using CM is not the proper way, use stock firmware to avoid possible bugs in CM, and you don't need to flash to Froyo in order to flash CM, you can do it from GB by flashing a Kernel with CWM support and you are good to go.
Good luck

Hi, thanks for the detailed reply.
I've just flashed back to the stock GB 2.3.3 firmware, however I'm having trouble figuring out how to install su?
With the stock firmware, it doesn't even tell me my carrier anymore, and just says "No service".

Network not registered issue

Hi Guys,
I am writing this Thread believing that I will get a solution as Yota company has not provided any solution after 15 days trouble shooting. I just brought the phone from Russian seller through eBay.com to India and after 2 months of fight from the local customs office I just got my phone. I was very happy and was floating in air to have the first dual screen phone in my hand. The phone was flawless with dual screen was working awesome. The phone came with lollipop update. I switched on the phone with out inserting the simcard, the phone prompted for a small 350 MB update and I just update the phone. Then I just inserted the Simcard after which i started facing issue. The issue was the phone is able to read and shoe the service provider name but there was no network signal and it was showing only emergency calls. When i tried to make calls it showed network no registered. I tried with different simcard which resulted in the same issue. I though it might be a simcard issue and checked with my old phone but there was no simcard issue. So i just contacted the Yota tech team through mail to help me on this issue. They asked me do some basic troubleshooting but there was no use after 15 days they asked me to ship the phone to nearest service center which is in Russia. The issue is to and back from Russia customs will cost me the price of 2 Yotaphone fist generation phone price. So I through of resolving this issue myself and researched in online. I found that Samsung phones were also facing the same issue after update and tried all the solutions given in internet but there was no use. Finally there was a solution asking to root the phone and install the ariza patch which would solve the issue. I just rooted my phone and when I installed the ariza it showed it was not compilable for yotaphone 2. I just searched in XDA forums and could not find anyone reporting the similar issue with a solution. So I through of creating new thread in hope of getting a solution in this issue. Please help me in this issue by creating a patch or any solution which will me help me out of this. I am not able to use the phone as the basic call function is not even working reset the phone is a heaven.:crying::crying::crying:

Do you still have this problem?
I wasn't sure at first, I thought it was my sim card, but I have tried 2 different networks sims and they both get no signal in my Yotaphone 2...
The network's name does appear, so the sim must be being read somewhat, but I always get no signal.
I literally have no idea what to do.
I too turned the phone on without a simcard, flashed the RU latest rom, flashed TWRP, rooted it etc, surely that has nothing to do with it...?

@bharath9962 ! I fixed it!
I have no idea why this happened, and I spent a few hours trying to fix it, very angry. I downgraded to 4.4 to see if it would help, put back the native China rom that came with my phone (accidentally deleted my backup too...)
I bought a new sim card just for this phone because the old one did not 'work'.
This is not a popular phone so it's hard to find information, anyway... I'm very relieved now. I can only imagine you gave up...
I found the answer here - thewichitacomputerguy.com/blog/how-i-fixed-your-sim-card-does-not-allow-connection-network-g1
1. Open the phone dialer
2. Enter: *#*#4636#*#* (Once entered, you will be taken directly to a "Testing" page) [4636 spells INFO]
3. Tap Phone Information
4. Scroll to the bottom of the screen and you should see a button that says radio off. Hit this button and when it reads radio on Hit it again to turn the radio back on. <-- (Not a Typo)
I rebooted and waited a few seconds, no signal. I turned on airplane mode, turned it off, and it worked!
Now I can go back to RU 1.99 and reinstall all my stuff...

My country is in Asia but I believe this does not matter - the problem was that somehow the radio (cell phone function) was 'off'/glitched, and had to be turned on+off to make the phone function again. Using a different country's sim card would not fix this problem.
As I wrote above, we both share the fact that we first turned our phones on with no sim, and updated. Maybe just a coincidence...
Just try the guide and please let me know if it is fixed!

Fix for Yotaphone 2 YD206 from China
If you already flashed the phone to latest EU 5.0, you can skip 1-5
1. download via FTP: fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe and install
2. run flasher and download latest EU rom (2 - 5- 7)
3. turn off the phone and turn it on while holding volume down - this will boot the phone in "downloading..." mode
4. in the flasher press 1 (Flash the cellphone)
5. the phone is now on 5.0.0-EU1.1.124b and 2G is not working at all and 3G is connecting only to 2100 MHz (on my cell network)
6. download via FTP: fw.ydevices.com/YotaPhone2/Firmwares/CN/4.4.3-S01-003-CN1.0.3.32a.zip
7. unzip the file and copy \radio to c:\program files (x86)\yotaphone_flasher
8. run cmd and go to c:\program files (x86)\yotaphone_flasher
9. repeat step 3.
10. run next lines:
fastboot flash modem radio\NON-HLOS.bin
fastboot flash sbl1 radio\sbl1.mbn
fastboot flash rpm radio\rpm.mbn
fastboot flash tz radio\tz.mbn
11. reboot the phone and enjoy 2G and strong 3G signal

Hello!
I try to figure out what you did but I get stucked in number 10.
Actually I flashed my Yotaphone with the chinese radio the first time, but I don't get good connectivity.
Anyways I try to do what you wrote, but when I tipe the first line (first fastboot command), cmd keep saying waiting for the device... maybe is that I'm impatient but nothing happens.
I try other USB ports and nothing works...
So actually I don't know if I'm doing it right or if I have to wait for a longer period of time (10 minutes or more).
Any help would much appreciated.
Cheers!

Hi there,
you don't have ADB drivers installed. Google for "universal adb driver" and install. There is driver included with yota 5.0 firmware (C:\Program Files (x86)\yotaphone_flasher\Driver\Google), but any other adb driver should work as well.
And use original yota usb cable!!!
It shouldn't take more that a few seconds for those commands to execute.

Had the same problem
Hi all, I had the same problem when I flashed russian firmware (YD201) over my phone which originally had honkong firmware (YD206).
I can inform that for me it also worked to flash the Chinese firware with yotaflasher.
However, when I tried to only flash the radio, it seemed it did not work. So I flashed the complete chinese kitkat firmware with yotaflasher and then afterward just removed/renamed the radio folder when flashing the newest russian lollipop firmware. Everything working great now, even was able to do some ota's without any problems since the ota's did not update anything of the radio img's.
And indeed you first need to make sure that you have the fastboot drivers installed and your device gets recognized as fastboot device by your PC.
You can test this by doing "fastboot devices". If you device turns up there as a fastboot devices, then the drivers and connection from pc to phone are ok.
Good Luck!

Thank you deepmnd and tomgaga.
Actually I had to activate developer options... And then reinstall the ADB cause, aparently I had it but it didn't work.
After that the instructions worked perfectly, but I still have network issues.
I don't know if it is because I have a MVNO (Mobile virtual network operator) and the phone has to change between the networks ( the one that provides the network and the MVNO).
I think that when it changes from one net to the other is when I lose connectivity and sometimes I have to search the network and choose it manually.
So this problem actually happened to me and the solution was to activate Roaming services (but I dont' know if is actually the same problem).
Anyways I can see that I connect to EDGE, HSPA/HSDPA and LTE.
For sure there is a way to monitor the network and check wich ones works.
Another guess is that being a phone for the chinese market, and the lack of the 900mhz band is causing this ¿?
So at the moment I'm losing signal just by walking on the street and I live in a big city. It seems that LTE and H works fine but I don't have a a way to assure this.
When I will have a spare time I will try to reflash the phone with the instructions deepmnd provided and see if it will work.
Thank you for your help!
Any advice will be appreciated!!
Update:
I try tomgaga approach I will test it just to see if is the network or my provider

Does anybody know which bands different firmwares support?
Reception is incredibly bad in my case (206 flashed with EU firmware).
It'd be nice if somebody has any info on unlocking different bands for yotaphone2.

Here you have the bands

I have the same problem as you, I will try this weekend to downgrade to the older chinese rom and check if the reception get better.
And if then to the latest RU rom.

Thanks for that, it helps a lot to clear the situation regarding the two models.
Now, taking in account deepmnd´s solution above, would it be possible to find those missing bands from the original 206 which are not available to the updated (and then international, 201-) version and add them individually, file by file via the fastboot flashing?

I followed deepmnd's instructions, and my phone now connects to GSM/EDGE, which was not possible before using the EU Radio (latest EU rom). Thanks for this!
Unfortunately it now preferably (!) connects to EDGE, although the LTE/WCDMA-Option is prioritized. I can force the phone to connect to WCDMA by using the WCDMA-only-option, but in this case it does not commit a fallback to EDGE if 3G is missing and I have no connectivity at all, unless I change the band-options and force a connect to EDGE. I'd like it to switch between the bands automatically, as my YD201 did without problems (in Germany).
Any hints to solve this problem?
Thanks in advance, Knut

Thank you! I had missed calls and did not know what caused them. Then I noticed this happened when I was not on LTE network but on WCDMA or 2G network. And this seems to have solved the issue for me as well.

S7 Edge (SM-G935F Exynos) Carrier Flash ROM Question

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).

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.

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!

Baseband not found [XT1766 SPerry/Boost Mobile]

Somehow or another I have managed to screw up my modem on my SPerry XT1766 (Boost Mobile).
I only get Emergency Calls Only radio signal, Settings app and bootloader info shows Baseband Not Found or Unknown.
I tried using RSDLite to flash
XT1766_SPERRY_SPRINT_7.1.1_NCQS26.69-64-10_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC
which contains the fsg.mbn and NON-HLOS.bin files, but this doesn't seem to help. I've tried multiple firmwares with multiple different modems and nothing seems to be getting my modem up and going. Back when I originally updated I flashed the partition updater also. I have no idea what to do now. I'm downloading the 69-56 version to try that, but I doubt it'll be any different. If anyone has any idea on what to do that would be great. Thanks

Try my baseband updater from this thread. https://forum.xda-developers.com/mo.../rom-stock-android-7-1-1-rom-moto-e4-t3885821
It will attempt to update your baseband to the latest version (M8920_15000.280.06.58.06R) from firmware build NCQS26.68-64-11. If this doesn't work for you let me know, I may have a solution.

@Knuxyl
Are you on Boost network? I've seen the radio off problem with ppl using a different sim.

Yeah I already tried that but it jept giving me an error saying unknown command [ ]] or somrthing along those lines. i looked through the script and didnt see any typis. i think your NON-HLOS.img is different format than the NON-HLOS.bin files found in the stock firmwares, plus it's much larger. Anyways, tried a fastboot flash the modem with it and that didnt work either.

No I am not on a boost network but this problem goes more into firmware than network compatibility because the bootloadet itself isnt even recognizing the baseband. For the record I am still using a CDMA network like boost (Verizon)

Also as an update, the 56 version didn't fix it either

The latest update did that too many people. It won't work with a different sim. The radio will be off.
I bet if you put in a boost SIM, it would pop right on.
They changed something in the -8 firmware.
One guy building ROMs (not here anymore) made some changes to his build that got certain networks to work on his ROM.
He never got the chance to share exactly what he was changing.
It seems that if you booted the phone ever with the original sim inserted, it tripped a qfuse (of sorts) and it seems they have added a way for that particular reading to turn off the radio completely if you're not using one of their SIMs.

You are 100% on point. Sprint (and its subsidiaries) had Motorola Mobility to include code in an OTA update which would disable functionality of any network other than the original UICC (SIM). In other words, when you got a new Sprint compatible xt1766 (Sprint, Boost or Virgin Mobile), opened the box and booted the device with the preinstalled SIM in it, the xt1766 became forever locked to that network -- the OTA update carved that in stone. The update made it impossible to downgrade the baseband radio, killed all GSM functionality, and broke the radio on custom ROMs (the latter being unintended most likely). The only people I have heard of getting around this are the ones that didn't take the -8 OTA update. Like you were saying, I'd like to know what Jason M. done in his custom ROM to fix radio function, whereas at least the radio would work with the original SIM on a custom ROM. He said something about "adding missing symlinks" to the build.

I did this too somehow. I think this might bring your baseband back (it did for me), but... well, I'll get to the "but..." Anyway, Boot to TWRP, mount the Persist partition, then go to terminal or pull up an ADB shell and do:
chmod 0700 /persist/rfs/msm/mpss/datablock/id_00

Reboot with a SIM card inserted and voila, you maybe might have a baseband again. Hooray! Except in my particular case, I regained a baseband and then somehow lost an IMEI. Well, not really "lost," it's still there when I pull up the barcodes page... but on bootup it thinks it's 000000000000001. I still haven't ever fixed it, though I did manage to turn it to a single 0 somewhere along the line. Fkit.
But I don't know of anyone else who's lost their IMEI this way, and it's been too long ago and I've tried way too many failed fixes to remember what else could have triggered the problem to start with, so who knows. If you decide to try it, definitely make a backup of the Persist partition before you do anything...and make sure your backup turns out to be good first, not corrupt like mine turned out to be....sigh.

No signal after firmware update

Hi guys, I have an issue with my G6 H870.
I wanted to get back to stock ROM yesterday, so I tried to get it back by LG UP and UPPERCUT.
I've installed 20j firmware but then my G6 stuck on LG logo screen.
I was trying multiple firmware version.
I asked admin of lg-firmwares website to help me choose the right one.
After I send him my IMEI he told me that: "Model is LGH870, Region is NEU, Latest version is H87020i_00_OPEN_EU_OP_0322.kdz".
This version didn't work so I've installed the latest version of Nougat for the region NEU - "H87011i_00_OPEN_EU_OP_0108.kdz".
Now I have no signal all the time, tried to install another ones but every single one of them shows no signal. Even if I change LTE to only GSM or WCDMA.
How to fix this? What causes the problem?
EDIT. I have unlocked bootloader if that matters.
EDIT 2. If I check adb it shows H870DS - but I don't have dual sim:
"List of devices attached
LGH870DSabced8d3 device"
