So, other SIMs are working with different radio versions? I think that your phone is fine.

Might be a trouble from operator side. Check Telenor SIM on other phone.
If it will work - flash factory ship ROM on yor DHD and flash original radion version.
It's strange mystical part, but stock ROM resolves a lot of troubles

No success

Thanks for reply other sims works fine with ever version of radio only that telenor sim doesn't work as before flashing a new rom i put my DHD in airplane mode i think that is the main problem...
if i do same process with other sim ( before flashing other rom put DHD in airplane mode ) then that sim network will not work also..those sims will work fine in other cellphone.
like i use the same process( before flashing other rom put DHD in airplane mode ) with Mobilink sim it shows signals but when i call or sms it says Mobile network not available (in screenshot)
and when i use Telenor it says no service (in screenshot)
when i try to choose a mobile network manually in settings it says "your sim doesn't allow a connection to this network" (in screenshot).
and when i try to choose a mobile network automatically in settings it says "Can't connect to this network right now try again latter" (in screenshot).
other sims works fine
all screenshots are attached with other information

This Is strange... Is your device made in china or taiwan?
Reason for asking this question is that, taiwanese made DHD normally generate certain problems out of the bloom that usually makes no sense.
From my understanding, When you flash a rom, you format the data partition and this partition holds every change you made to the os during the time of use. So there isnt any reason why a mode you left your phone in before flashing another rom should have such an effect.
Have you tried inserting another sim from the same mobile operator?
Edit:: And what rom is that? It looks nice. Can you give me a link to it?

It cant be a simlock. It takes more than airplane mode to throw a device in sim lock.
And if it was sim lock, it would only accept one particular sim card and not accept some simcards and reject others.
These made in taiwan Desire HDs develop problems that dont mount up to any proper explanation, as i already said.
Like mine, its taiwanese made and when i take out the simcard, it runs smoothly, but as soon as i insert a simcard, the device becomes laggy/slow. i have tried so many things but they all dont seem to work. This isnt the only problem, there are others.
This only leaves me with the conclusion that, the taiwan made DHDs are immetations/fake.

Your phone probably doesnt supprt the network frequency that your carrier runs on

before flash works OK, problem with network was after flash official ROM

same problem here before it was fine after flashing cellular service keeps on dropping

Hi guys, I'm facing the same problem. Did you find solution?

[Q] So How does this actually work?

I picked up a pre-owned Gold G3 yesterday, my last one went pop!
This new G3, is Sim Unlocked, but with a Vodafone UK rom (V10a.235.15). After researching and reading around.. the G3 has EFS, so I followed the KDZ back to stock guide and flashed the Open EU rom, which went without any issues and seemed as if it had flashed and replaced the VF Rom, but it still has the VF splash screen, a VF updates Icon (Which can be removed) and software version, yet the G3 still detected and Loaded in my EE UK APN settings and no sign of any VF APN.
http://forum.xda-developers.com/showthread.php?t=2785089
So am I right in thinking.. If I wanted to make this a full UK unbranded phone, so no splash screen with a software V10a.EUR.XX.. I would have to Jailbreak the EFS partition and Replace VFRom stored on the EFS with the EUR-XX rom.
OR am I wrong entirely, so... How does this work
There are so many threads on here, that ask the same questions in different ways, hence why Im a litle confused as how this works
Thanks

Wait Wait Wait
So you cant manually import APN settings right? How about flashing a Rom from another European country?
Dont tamper with the EFS partition under any circumstances. If you do you wont have a IMEI and your phone will be worthless. Carrier branding does not occur within the EFS partition
I remember my carrier apps disappeared from Update Center when i upgraded my Australian firmware to a Taiwan Firmware so im pretty sure it might work for you.
When you flash the KDZ make sure you flash it using CSE Flash Mode

Can I just be clear before I answer... The G3 I bought is Branded to Vodafone UK, I am personally on EE UK and Im trying to remove the Vodafone Branding and make it a factory unlocked unbranded G3.
Thanks for the reply friend. I didnt have to enter any EE APN settings, they were already there, so not sure how that was... because I didnt enter them. Glad to hear its not the EFS, because I would rather use a branded phone and have it working than change its file system and mess it up. Also, I know the guide doesnt state it but I turned ON USB Debugging, would that make a difference
I followed the guide closely so did flash using CSE. Ill now flash another countries KDZ and let you know how i get on?
Could it be that Vodafone UK is the EU Open Rom, just a few minor changes..... What I dont understand is...
The EUR Open Rom flashes perfectly fine, reboots and starts... so why after a perfect flash using CSE, is the Vodafone UK rom still there. Any Ideas.

Im afraid no Luck... I flashed Open France, still booted to VF rom with VF software on it v.10a-235-15), then installed "Italy Orange", which actually worked, booted up a clean LG rom BUT, even though its v.10a, When trying OTA update, it said I was n the latest OS, which is no good, then using LG PC Sync.. it just updated to the UK VF rom again (20h).
So I took a long shot and flashed Open UK, still the same.... boots into VF splash screen and software.. so, Im at a loss. This is why I reckon carriers hide a rom on the EFS partition.
Any thing to add
Thanks

Was on oreo and did flash all to 7.1 by mistake.

So I was on Oreo and accidentally flashed back to 7.1.
Didn't brick it but now it doesn't recognize my sim even after flashing back to Oreo.
I tried to fastboot the tmo baseband but no luck there.
Anyone run across this or have any suggestions?

That was one of the 1st thing I ran across in the Oreo update thread. With development just really getting fired up I'll be surprised if you find a fix. If. I was you I would flash the mod that hides the unlocked bootloader warning and take it to TMobile. It's only a 5 dollor charge for defective devices. I've returned a total brick before.

So I am on the same board. The problem is I'm in UK and I cant claim warranty repair. Also my warranty was void in December soon when I generated bootloader unlock key.
SO what have I tried so far?
Hard brick bootloader to state when it is Qualcomm loader- only blank flash and Oreo Flash All is able to bring it back to live.
Ive also tried boot from B slot in twrp but it looks like my B partition is messed up. Fastboot will show red warning about no flashable A/B slot and only oreo flash can get it back to boot because it will oem lock itself.
When I get back fully on unlocked bootloader to 7.1.1 I cant update via adb sideload or update menu in settings. Both will fail.
Sim looks like it is detected on start but when taken out and slided back in it wont show up.
I have QCN area backed up with nv data but it wont help me.
Please note when boot is bricked oreo flash all will flash it on locked bootloader and will not show warning screen at all about botloader. However I was unable to boot to recovery from that point so I had to unlock it and flash 7.1.1 then oreo again.
So if someone could do nandroid backup of clear not set up rom it would be great. I can try restore it. I dont even know if twrp is able to do backup on A/B device.
Also if someone could read NV data from phone and share it ( from phone with working radio of course) would be really appreciated.

Can someone PM me NV backup? I need urgently qcn file. I think my hw partition is messed up. Please don't share it in this post as it can contain IMEI.

this is what i did, and why there is a giant post in caps in the thread that says not to do this. You essentially end up with a bootloader mismatch which hoses the radio. the only solution is a replacement.
and DONT DOWNGRADE !!!

Sorry but warning isn't clear. I did not enjoy Oreo and was looking for unlock method.
Also bootloader match to my current Oreo rom and radio but still no sim detected so I think it is hw partition messed up. When I flash retail Oreo on it bootloader just change itself to retail Oreo version. Still no sim.
Device is useable as paperweight with WiFi

I think I've found a way to unbrick your phones guys!
If someone still has their bricked phone could they tell me what state they're in? I managed to successfully unbrick mines but had to stay on 8.0

Everything about the phone works 100% except the Sim slot. It's like it can't read the Sim. It knows there is a sim in, but it can't access it.
On Oreo oem retail version.

I'm happy to stay on 8 but need my sim get back to life. All works fine except SIM card is not detected.
My phone boot as normal. When downgraded it won't accept ota's. It won't install it via sideload too. SIM card remain undetected no matter what rom and what version( T-Mobile, retail, etc) when I try to boot from slot B via twrp it won't boot. It will show bootloader screen with unbootable a/B partition.

Not OP, or guy with a link, but I did a similar bad thing and ended up on the retail Oreo without working SIM. What I did was take the modem file (the one that you fastboot flash to modem) from the tmo oreo zip and replaced the modem file in the retail oreo zip with the tmo one -- just change the name of the tmo modem file to the one that comes in the retail oreo zip and then run the retail flashall.
Still no way to get the latest tmo update that fixes some volte issues, though. Since I purchased within 14 days, I just added insurance and will probably end up drowning the phone to replace it... unless someone has a better idea. :/

guys i tried blank flash oreo on mine bricked tmobile moto z2 force and it isnt working, any help would be great on this , thanks.. and also i have tried many blank flashes some for even other moto phone models none worked so far.. one or two of them got really close the oreo one did but failed at last part... tried about hundred times and yes i even tried holding down power and volume button with no success it didnt work it did though recognize the phone but still failed trying to boot or flash it though... seems to me it needs either up to date or just different blank flash it seems, but i dont know that for sure...

Restore original carrier software, with multi CSC rom to recover VoLTE

Hi, this is my first post. And im new on this teme of the Multi CSC roms.
I have a question, I get a ROM from SamMobile of my carrier Telcel in Mexico (TCE). I understand that the rom is multi csc, but when I flashed it all the bloatware (that in this case i need, VoLTE is only in my carrier) is from Claro (CHL), and I need it from Telcel. I sent a mail to SamMobile explaining this but they only answered me that the room its ok, the rom is multi CSC.
The CSC version that the system shows me is CHL/CHL/TCE, and I need TCE/TCE/TCE.
Anyone knows what I should do?

From my experience changing firmwares to enable volte, to fully restore csc it's flashing the firmware TCE, download from samfirm app on computer then factory reset from the firmware you have, flash TCE firmware with Odin and this it's the trick you need to have another carrier sim(no telcel) before flash the firmware TCE, wait for boot(don't put an account) when you are on the home screen turn off then enter recovery and factory reset and reboot, here when you swap the Sims, put the telcel sim on it and wait to fully boot and when you see the welcome screen you see a message that say the sim card it's different and need to reset, accept and wait for boot go to settings and check csc and now would be TCE\TCE\TCE

In my quest for fully change the csc without flash twrp and root to lose Knox warranty I ended with some smart guy that say the first two can be changed with flashing firmwares and the last one can only changed with root for that reason if you flash a different firmware region the two changed with the default csc on the multi csc and the last one stay same for example in this case MXO/MXO/TCE and the only way to return all the same it's using other carrier sim card temp until you flash the original firmware and then factory reset and when reboots swap sims putting the original carrier sim card in this particular case telcel

Thank you for your answer! But, let me see if I understood.
1- Put a sim from another carrier.
2- Factory Reset.
3- Flash the phone.
4- Turn on, and configure it.
5- Factory reset (again?)
6- Then put the Telcel SIM, before it starts completely
7- And finaly, in the "Welcome" screen, when the phone shows the message of the sim changed, perform another factory reset.
Let me know if I am right,
Right now I don't have another sim, i think that its rare that someone has another carrier But when I have it ill tell you what happenned

Depends what do you want to do.
In this particular case try to get original CSC TCE/TCE/TCE
He has CH/CH/TCE
If you wanna recover original CSC you need to have another carrier sim on step 1 and when you flash the original firmware go to recovery amd factory reset from there and when you put reboot in the process of boot you swap sims, put the original carrier, firmware sim

Do you know if the phone must be unlocked? I tried to do it but when I put the other sim, asks me for the carrier unlock code. The phone doesn't show me the message of the sim changed.
I've been some research and I found that Claro is Telcel in the rest of America Latina. Maybe its the reason that shows me Claro.
I tried the CSC secret code *#272*IMEI# and nothing happens, how i know if a ROM would let me do this?

For that only flashing another firmware if you are from Mexico could you install MXO firmware it's the generic Mexican clean version and that you get MXO/MXO/TCE
The last one remains TCE this only can be change with root.

Actually I have the MXO/MXO/TCE, i've tried with the TCE rom, but still showing Claro. And these two roms doesn't allow the csc secret code. Don't you know what rom allows the csc secret code? I don't wanna try multiple roms from sammobile the download speeds are frustrating.

Try download from samfirm it's more fastest download the full firmware it's pc exe.
Do you try the step mention above? With other sim factory reset from recovery and swap sims, when phone boots tells you the sim change and need to reset and then you get TCE/TCE/TCE

Wow thank you! Im downloading it right now at 2.2 mb/s, compared with 100 kb/s of sammobile.
I tried anything and nothing works, I think that the unique solution is try with another OWA roms, I don't know if Telcel and Claro SIM's have similar identifiers and thats why returns me to Claro. Don't you know if there are roms with the csc menu activated?

Nope, do you think that the carrier lock relates with the problem?
Which sim carrier did you try?
Could I have problems if I try ATT or Movistar roms?

My phone was originally from att but I unlocked it and now use it on telcel and I want to use VoLTE with telcel. I would like to try the att or movistar firmwares but the problem is that (for what I've read) since the last att update was from like March the bootloader is older (v1) compared to telcel or MXO (v2) so you can't downgrade.
What carrier are you using? And what do you want it to be?

As far I know to get VoLTE on telcel you need to buy phone directly with them, because uses the imei to enable that function

Yes, I thought so too, but the thing is I went to Telcel and asked and the told me that my phone SHOULD have VoLTE but I think that may be associated with my phone number, (since I've had that number for a long time), and not with the IMEI
