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!

[Q] S4 Problem with network WCDMA (3g)

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.

strange problem with sim card

Hi there,
I think problem is intractable . It is a Samsung I9505 recognizing a sim and some not. I assumed it was the flex of the sim card , so buy him a new one giving the same result.
I 've just released by IMEI but that's not the problem. The phone will have 3 years old from Orange.
Where not directly detect and asks pin or anything just he says no sim inserted.
I have installed the latest free firmware PHE is SamMobile and nothing has changed.
Fixed network files and either Chimera .
Anyone have any idea that can happen?

Flash latest firmware and modem?

only the latest firmware one file in odin box pda

someone else to help me, not you think of anything else?

Is your phone unlocked to use other sim cards than Organe ones?

Is the sim not recognized at all or are you getting the message that the sim card was removed?

Unable to connect with mobile network

hello, here is my problem.
i bought a 2nd ZenFone 2 Laser (ZE500KG/Z00RD). My phone are able to connect to mobile network, but only on GSM network. I'm unable to connect to WCDMA network. I think it's caused by my sim card, or the network signal, but both of that it's okay. Every time i connect my phone to WCDMA network it's show pop up say that 'Can't connect to this network right now. Try again later.' and 'Managed Roaming (SUB 1). The IMEI are fine, it's matches with the IMEI on box. My phone now are rooted, bootloader unlocked.
I hope somebody can help me with it, because my phone now is like a expensive mp3 player without internet.

Try updating your baseband. If that doesn't work, try flashing ZE500KL's marshmallow (v13.xx) baseband. Here's the link to my baseband collection http://forum.xda-developers.com/zenfone-2-laser/general/collection-modem-baseband-stock-t3395811
Post your results here.
Edit: You can use ZE500KL's twrp recovery http://forum.xda-developers.com/zen...twrp-3-0-2-0-unofficial-t3377991#post66833804
OR just flash the baseband (.bin file) using "fastboot flash modem <filename>"

SIM 1 Slot is not Detecting

Previously i have rooted my mobile and it was working fine. I tried to install new software update, So i flashed the stock firmware i lost my wifi and network connectivity (both sim cards were not detecting). I flashed again stock firmware which was suggested by some senior member in XDA. After flashing that firmware i got my wifi and mobile network but my SIM 1 SLOT is not detecting. Tried to wipe data and flashed another stock firmware still the same issue occurs. I tried swapping sim cards but it is not detecting in SIM 1 slot which is detecting in SIM 2 slot.
Found that IMEI is there.
Is this software issue or hardware issue?
Please give any solution.
