3# if its a hardware probleme how can i solve it?
4# iam now at kitkat official..can i flash just the modem of the brazilian 4.2.2 jeallybean in my kitkat firmoire?
@fburgos any comment please??
I think you could downgrade modem only from that Brazilian firmware which boot loader is 2.0.
Last thing you could try is to do a e2fsck from adb on your partitions.
Again I'll ask about your Knox status is it 0x0 go to your download mode (Odin mode) if its under warranty send it to service, just because flashing don't seem to solve your problem.
This is something offtopic but I'll tell you why I think it's a hardware thing I could be wrong
I've own 2 s4 mini i9192, First one is pre Knox but I cracked the screen it worked flawless with my carrier 2g and 3g roted since day one.
Second came with Knox bootloader and I was afraid of the warranty so I didn't root it, it was flawless, then cm11 for the dual sim variant came out, installed a recovery and flashed cm11 knox became knox0x1 and 3g stopped working just showings emergency call tried many different modems to make 3g work in cm11 but none worked I flashed back stock and to my surprise 3g on my carrier didn't worked some carriers worked nice but not in mine.
Then I swapped screens with the old phone and that was the solution to my 3g problem same sims but different hardware.

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

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).

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.

Pls Lets Use The Other Thread.
Using official (as well as silviu's ROM) for Samsung Galaxy S4 mIni duos (i9192) on Jelly Bean, I could use HSPA+ network (when available). However my phone was rebooting everytime I activated my 3G/HSPA+ on one of the two sim cards... very annoying, my only solution was to deactivate 3G and work on Wi-Fi to avoid constant rebooting.
Therefore I tried kitkat version : it's even worse concerning rebooting plus I have no HSPA+ at all (same phone, same sim card, same network, same place) !! Modified ROM of Silviu corrected rebooting issue, but still no HSPA+ anymore !!
Can someone help ?

Hello, thank you for your quick reply !
I'm from BELGIUM and tried a lot of things without success... you are my last hope to solve.
I'm afraid I was too fast in saying rebooting issue was solved with your kitkat rom : it is not rebooting but I still loose network on both sim cards after activating 3G on one of them (and using it). Behaviour is slightly different as I don't get immediately pin code screen or rebooting, but I have to reboot and enter pin codes again to reactivate network.
You may be right about changing modem : what do you suggest ? I found one of your posts on this forum with a lot of modems : are they all usable with kitkat ?

Strange behavior u have there. unfortunately no, only 3 modems for now for KitKat . Russia, India, Chile
I think i only had one full network drop on both SIM since Kitkat and that was caused by Phone.apk crash . But my network came back online in 10 15 seconds or so.
On Jb, i had more Phone.apk crashes but those fully lock the phone and i had to force shutdown . ~1 / week or so
I have no clue what to advise u unfortunately. Sorry
Did u try without PIN-codes ? I don`t use them

Yes, I tried... unsuccessfull
Let me resume, I have now 1 more issue on Kitkat comparing to JB :
a) loosing network when both sim cards active AND 3g active on one of them (i.e. be asked for pin codes, unexpected rebooting, just nothing to see but get voicemail when calling my own numbers from external phone)
b) no HSPA+ (Kitkat only)
I tried to downgrade to JB in order to have at least HSPA+, but it gives an error ! ?
Please help how to proceed for downgrade to JB stock rom ?!

Same issue here.
Same issue here. After upgrading to Kitkat, never been able to connect again to HSPA+ signal. When I try network mode "GSM/WCDMA" I get EDGE signal then when I choose network mode to "WCDMA" only, I have a signal but no internet and the symbol "H+" or "H" doesn't appear on the top of the screen.
So far, managed to root my Korean F240L, still running 4.4.2 for now until there's a root for Lollipop. Haven't managed to see any 4G signal in the UK since I got it , get 3G sporadically but the reception is way worse than the same sim card in my old Nexus 4. Network is Giff Gaff (ie O2) , should I consider going for a UK baseband update ?
Right ok, since found out that the Korean version doesn't support UK 4G. Is it possible to change this ?

If the phone doesn't support the LTE bands your desired carrier offers, then no, you're boned.
Think I'm in a similar situation
Got an E986 from Germany running 4.4.2 KitKat (E98620a-EUR-XX), it works great on 3G in the UK but NO 4G at all on my Three 4G Sim card. Tried enabling it in the hidden phone menu - no joy.
I thought I would be able to get 4G working by rooting and re-flashing but by god I cannot get this thing rooted despite my best attempts from trying all the techniques on here
Thought if I downgraded to 4.1.2 then I would have better luck rooting, but can't seem to download a .kdz that isn't corrupted when I try the LG FlashTool

You cant change the bands of a phone by flashing other things. If it doesnt work it most likely wont be able too.
Hey, So, I realized I posted a forum about this with an "anonymous" account.. And sorry about that.
Anyways, My issue is, my darn phone will drop the network, and decides to connect to a rogers or telus Network Operator instead of Bell (or just completely dropping the network entirely). I did the unlock hack through the original baseband, then updated to cyanogen 12.1 and installed the I317MVLUDNF3 modem, Same issues. I just dealt with it but am wanting to try to fix this. I recently moved to Resurrection Remix 6.0.1 (which, by the by, is amazing) and its gotten better reception, but same darn issue.
So, How do i go along to fix this? Any way through xposed or root or WHATEVER cause this makes the phone really unreliable.

I'm downloading the mvludnf4 modem, and i have the latest bootloader from 4.4.2.. So, lets see if this modem fixes it..
Any other ideas?
If it seems to work properly on a stock rom, maybe flash back a completely stock rom, flash twrp, and then a custom rom?

Sorry for the late reply. I flashed the nf4 modem and reception is better.. Battery life sucks but oh well. I think this is a hardware issue.. I'm getting around -90 to -110dbm and 0-7 asu MAX. Maybe my antenna is busted?

And maybe the dialer unlock causes this? I could try getting it properly unlocked? Any insight on how carrier locks work?
I had an i317m that was locked to Telus running stock kk.
I used Odin to flash a stock 4.1.1 Samsung rom, sim unlocked the phone via the dialler menu, flashed back to the latest kk, pass the phone to a relative, and he has been using it for years on Rogers with no signal issues afaik. It may be possible that this method of unlocking causes a signal issue but I can't be sure.
In the thread that was linked, it looks like it could be a hardware problem.
Hmm.. Well I tore the phone apart and the antennas seem to be jn place.. The 4g antenna is alot smaller then the GT n7100's. Maybe that has something to do with it.. That or this phone has trouble with bell frequencies?

Then i am completely lost.. Something must be hardware related.
Not 100% sure but doesn't the phones imei number have to be registered on the network it's using. Maybe imei has something to do with it.
Just a copy and paste off the internet instead of linking to a website. I think imei is the problem.
What is IMEI?
Mobile phones, except the serial number have also IMEI number. IMEI — International Mobile Equipment Identity. IMEI — a common standard for all mobile devices, which is assigned to the phone at the time of manufacture it in the factory. It's the unique number, which is broadcasting to the carrier to authorize phone in the network. Structure of the IMEI is the same for all phones regardless of manufacturer. IMEI number is also used to track and block lost or stolen phones by the carrier, which further prevents to use of such devices. However, blocking IMEI in one carrier network have no effect in others networks.

Well.. If it was an imei issue wouldnt it be getting no signal at all since the phone can't register on the network?
Canadian carriers don't need the imei to be registered, only the SIM card.
Hello, Hope all are well.
My device Note 10+ 5g, Model N976N, (Carrier_ID: KOO)
I cant get Signal from SIM, The device did not recognize the SIM cards.
A technician make software for the device, and, in About phone, I can see the Model number(SM-N975F).. I've make some software chages/flashes and the device was corrupted.
A technician make software and, in About phone, I can see the Model number(SM-N976B/DS).. I got the signal for one time then loose it.
What is ur advice?
Can I flash N976Q with (KSA or XSG - Arabic country code) ? Still have Arabic Language and Signal in 2-SIMs ?
Thanks in advance.
Hello mohgaza,
To me it is a bit hard to understand your problem.
has your sim card ever worked
If so: what happened / what did you do that caused the problem
please try to improve your question.
You also state two different model numbers in your question. Why is that? What technician are you talking about?

This could be a loose contact or some working configuration between a lot of nonworking ones or something completely different. What country do you want to use your phone in? The choice of the modem file should usually depend on that.
Hello, I'll clarify:
SIM cards worked for less than an hour, JUST restarted and lost SIM signals.
Technician was trying to resolve the problem.
Worked well on n975f, BUT I flashed other firmware by mistake,
Then I went back to the technician and he tried n976b.
My carrier is Israel / Palestine, and I want to activate the 2-SIMs
So If the N975F Version works well, why don't you flash it?

It seems because I've flashed the most latest, and cant DOWNGRADE ..
that is becuase the phone has a patched IMEI try searching auto patch roms and install it will help you. or take it a better phone technician who has proper flashing boxes like Chimera it will patch the imei.
