Not in this topic I had written. But as I wrote something that could help it - maybe you should do factory reset ??
Region?
Did you obtain the working handset from the same nation as the handset with the problem?
Which nation are you trying to connect from?

I'm having the same issue but, for what it seems, it should be a config file... try posting the question in the Ace-i's forum.. at least it's the same family model as the Ace-M (which I also own).
Maybe it has to do with CSC...

already post question but no one answered it
In case anyone is facing this issue, I resolved it by flashing an S5830C's NVRAM, it has to do with the NVRAM which contains the actual baseband (800/900/1800/1900 etc..), you can find it in the Bootloader package:

Hi, the file is in 7z because it's a whole firmware, but to fix the 3g issue in a S5830C/M you must use ONLY the Bootloader part of the flash, you'll know it because the tar part corresponding to it, has a file inside named like "HEDGE_NVRAM" and something else :silly: make sure to use the PIT corresponding to the cooperve, which you can find in the tutorial by @feetsonfire about how to recover from a brick.
Try first with Odin V3 1.84 if it doesn't work, try it with Odin V3 3.07.
There is no need for doing anything else! No recovery nor anything else related to it, just what I exposed in my post!

Hi all, I have a problem with 3g.
I bought s4 i9505 and it was on 4.2, I had problem with slow internet, so I called operator and they told me to turn on WCDMA only in settings..
When i turn WCDMA only on, it loose my network (emergency calls only), and i have no network at all.. when i put wcdma/gsm automaticly it has normal network..
So i thought its problem in firmware, so today i fleshed 4.4.2 with odin.
Now i have same problem, no network with wcdma only..
I serached internet and i tried several programs for 3g, but nothing worked.. any solution ? thx
did you try another simcard?

Some problems can appears:
1. Type *#1234# and paste here what appears. Continue with the step 2 if you have wrong CSC.
2. Wrong CSC. Solution: Install Kies 3 for know ur CSC (pic 1). Go to Sammobile.com and download the correct firmware 4.4.2 (correct region) for your device.
3. Flash again this firmware and let the process finish till the final. Dial again *#1234# and verify if all is correct like the firmware you downloaded and installed before. Flash again same firmware if not.

this is what it writes
Might be a corrupted EFS folder.
I have had the same problem for 3 weeks now. I've tried searching for a solution here and in other online sites to no avail. I personally tried flashing a new stock rom, flashed some odd number of modems, tried factory resetting etc. Nothing worked. I'm afraid it might be due to corrupted EFS folder which I still don't know how to repair.

i installed custom rom and still have no 3g ? solution any1 ???
Hi good people, I am facing a problem. Around 8 hours back I tried calling someone but the call didn't connect so I restarted the phone and then I lost the network. I tried reboot, flashed different ROMs (unofficial CM14, cm13 nightly build n MM nougat backup), tried with GAPPS and without GAPPS but the problem is persisting. I even tried swapping the Sim cards before that but of no use. I tried debugging by using *#*#4636#*#* but ping test is failed and also there is "TURN RADIO ON" I believe ideally it should be "TURN RADIO OFF". please have a look at the screenshots. I'm almost dying without making important calls.
Update: Guys I have got it working.. Kindly look into my below posts. Please don't misguide people for small issues.
Thanks
In the screenshot we can also see, GSM SERVICE IS OFF. it stays the same even after clean flashing a new custom ROM.
Got it working. Flashed latest COS ROM file however the situation was still the same. Then I removed sim, switched on airplane mode restarted. After reboot inserted Sim then again restarted n then I got the signal
1. Removed Sim card, switched on airplane mode from both power menu and notification toggle.
2. Restart, inserted Sim card and switched off airplane setting from setting. (Notification toggle and power menu didn't work) then got the network.
Please note I tried with only one sim in sim 1 tray. Later I got the network for 2nd sim as well

Which rom did you flash and what was your method of flashing?
You also said simply flashing didn't work. It was what you did with reboot, aeroplane mode and taking out and reinsert the Sim that worked?
I've had the same problem for almost a month now... and i gave my phone to the service center. They called up to inform me that its a motherboard failure and they'll fix it.. I'll provide further info when I get my phone back (probably in 3-4 days)
P.S I tried almost every method to make it work. So if you couldn't make it work in first 2 days or so, dont waste your time and just give it for the servicing (make sure its in Stock OS so that they dont ask any questions about root xD )

I flashed almost every latest ROM. But no ROM got the network back. So as a last resort I flashed COS 12.1 and still didn't get the network. Then I removed both the sims, activated flight mode restarted the device, left it couple of minutes and inserted only one sim in first slot. Holla I got the network. Then everything is back to normal
If u r facing the same problem I would suggest u to activate flight mode n restart. If it doesn't work try by removing sim cards, if it still doesn't work try COS 12.1.

Usual procedure of flashing. Wipe cache, dalvik, system and data. Flash ROM + Gapps. Reboot
Try to search in the forum. There is a lot of threads with the same problem with the Zuk Z1. It is a hardware problem.

Your modem and baseband sections may be damaged. Modem structure is hidden under qualcomm structure. To Access and repair those sections, you need to do some modifications. I managed to make my Zuk Z1 worked again with some tweaking. Altering that part of the phone is illegal due to its restricted elements such as IMEI number. That's why I cannot post a tutorial here. İt is not allowed. However, I can help you if you personally contact me. I hope you get your signal back soon.

Please follow xda rules and don't tell people illegal things where they get in trouble. Keep in mind, that's not an illegal forum
Sure thing but I have already mentioned it. I didn't post anything illegal. So, take it easy.

Hi, I haven't still gone to the service centre. Kindly pm me the tutorial for getting signals back.
I've searched and done so many hotfixes but
Nothing work and I think it's time to ask the experts.
Here's the Problem:
My Phone was in a HardBrick, then Gladly I've made it back
by reflashing the Stock Rom of Cool 1 (EUI 5.8.18s) using QFIL
And then I noticed that there is no network signal even though the sim card is being detected. I've searched on Google on how to fix it and I find out that it must be the IMEI and I re-write the Original IMEI from the Box on my Device successfully but still, nothing happened, I still have no Network Signal. I've done reflashing again through TWRP But still, nothing happened, I tried to switch to (EUI 5.8.17s / 5.9.26s / JUI and MIUI 9) roms. I also tried the *#*#4636#*#* and change the unknown to WCDM / LTE and everything is still the same No Network Signal.
Now I am wondering if it is because I inputted an International IMEI which is written in the Box of this phone, or might be because of my baseband or kernel.
By the way, I'm from the Philippines I'm using (Globe/Smart) Teleco's Sim.
If there's anyone who could show me the right thing to fix my device, your help will be appreciated.
If You are also suffering a HardBrick Case with the same device I am willing to help you to the best of I can do.

Hi there!
I had the same problem, tried rebuilding IMEI's even from my other phones etc. After rebuilding IMEI, appliying qcn with QFIL (after changing to diagnostic mode)... IMEI was available, but network won't work.

My phone:

Just try that, you have nothing to loose. First step - let's network work
