Hey all! Something very strange has happened, and i'm struggling to find an explanation. Running CM9 latest nightly. Got carried flashing modems, and after rebooting the phone i found i had no signal, so just kept flashing away and no matter what i tried, still no signal. Restored stock then got back to CM9, but still no signal. Restored a nandroid backup to Team ICSSGS and signal finally came back, albeit quite alot slower than before!
When i used to rest my phone on my desk, it would sit idle in 3G until it needed H. Now whenever i rest my phone on my desk it permanently says H, until i leave my house and it returns to idle 3G.. Is there any possible explanation for this? Also any possible explanation why my speeds are slower than before, even though i've factory reset from stock?
Maybe you fcked up your modem ^_^
Try KF1 or KB3

But then why did it not revert to normal when I completely wiped and reflashed back to stock gingerbread just like I have so many times before it?
I've previously tried KF1 but got shocking results. Tried it again, and strangely enough I got the 3G signal back (but was very poor). Went back to JW4, and the issue started up again!
Any ideas??

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?
I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.
Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.
I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help
Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?
Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!
Hi guys,
I already have some experience in changing ROM, and so on.
Recently, I gave up the experimental ROMs that have always worked well for back to cyanogem stable 7.2.
The first week was very good, but in one afternoon, for no apparent reason, my signal disappeared. The smartphone settings showed me that my number was +0000000000, the imei was shown correctly, but for some reason imei_sv was unknown. Put other roms, but the problem persisted. So I decided to go back to the stock ROM, I lost my root and CWM. Surprisingly, at first, I could make a call and receive another. But after the excitement, the same problem again.
Sometimes, the settings show my number correctly, others turn to show +000000000 ...
Nevertheless, the display shows me a good sign, and the phone recognizes messages in my mailbox.
* Detail: I can not in any way put CWM. I spent the whole day trying, and absolutely all the methods that the internet gives me do not work.
UPDATE: Finally now I have CWM, but the problems are present.
Rom: European stock v30a - Android 4.0.4
Baseband version: 1035.21_20121130
If someone can help me, would be very grateful!

I did not do this procedure. But I turned it into a brick, and formated all partitions and redid them with a fantastic tool here forum, All-In-One Toolkit -> http://forum.xda-developers.com/showthread.php? t = 2020737. This procedure can, by itself, restore a corrupted imei or delete data cal?
If not, how could I do this? And because it is corrupt without any procedure? I was at home and no apparent reason the phone lost signal. At 13:00 he had signal, and at 14:00 had no more.
I considered another possibility: virus in sim card.
This test will only be able to do tomorrow, using a sim card that is not "infected", if that would be the problem.
UPDATE: Today I bought a new sim card and tested it with the stock rom newly formatted. I had the same problem, but strangely, the first few minutes of use, everything works. After a few minutes of use, the signal sim no longer works, and after a few hours, the smartphone connects on a rece wifi, but the signal does not stabilize: connects but does not have internet access.
REALLY DO NOT IDEA HOW TO SOLVE THIS!
I really need help!

You really should try Erase CAL data. http://forum.xda-developers.com/showthread.php?t=2087215&highlight=wifi the first Post what you need. If you having problems with restoring your imei then use putty instead of hyperterminal
I did not do this procedure, but deleted all the partitions and redid them, and I believe it made the signal back. Thank you all for the help!
UPDATE: The problem is present again! I restored Imei, erased CAL data, change billions of basebands and no sucess. If I search for networks, it´s fix, but only any minuts, and the problem returns again. I have sucess for any days, but the sms were frequently lost, and after, my signal losts completly. It´s a possible hardware problem?
I really need professional help of my friends of XDA.
You are tried to erase cal data again by smartflash using 30B Rom and Baseband 30B?you o2x is from china or korea?

I flashed PA from Cynogen and all was working well when suddenly my signal went to 0. I thought that there was no reception but after sometime noticed that it was still like that. Tried this sim on another phone and it worked. Tried a new sim on this phone and it was not working. Did a clean flash of PA, flashed CM. The problem is still there. Any one else faced this issue before?
yes many a times, use the search.... cause you are not making me go through my profile just to copy paste the fix in the lpy thread.

so this morning, after reflashing VJ's slim bean rom, i noticed that my wifi wont turn on. i would slide it to [on] and it says "turning on wifi" but it get stuck there and the button becomes grayed out [off].
i have tried reflashing the rom
i have tried complete wipe
(sd,factory,cache,/boot,/system,/data and etc etc etc)
i did use blackrose prior to flashing the rom to adjust the hboot again, though that shouldnt cause this issue right?
what seems to be the problem here? i have been using VJ's rom for like 2 months stable and this has never occured.

I had the same problem. Ended up switching to Evervolv KitKat. Never looked back.

Did you finally solve it? I have the same problem with Evervolv's Kitkat. Posted details here. It doesn't seem very common, just found you with similar problems, and this other post.

oddly enough, i clean flashed the rom one last time and eventually the problem fixed itself. after a few days it was back to normal
some things i did try (not sure if it helped or not)
-airplane mode on for a while and then off
-power off phone and take battery/sd/sim card out and let it sit for a few hours
-i got to a point where i could "turn wifi on" (drag slider to ON) and i left it there permanently until it fixed itself
Hey everyone, so I just recently upgraded my Note 4 from KK to LP, but during the process, I had to flash the Baseband and modem before I flashed the LP ROM. I then flashed the ROM after I did that, and ended up with no network... I'm still able to make calls ONLY when I'm connected and close enough to the WiFi, texting is still fine I believe. So then I tried going through the process of downgrading to see if that would relieve the problem of my network issue, but it still isn't even working. Even after doing the process in reverse, flashing the baseband and modem before flashing my ROM.
I'd like to add that I did take apart my phone because my screen needed replacing, so I took apart my phone to see if I made my signal cables loose, they were, but then I popped them back in again, turned on my phone to see if that was the issue, and it still doesn't work, as well as my hardware back button doesn't work anymore so I have been using a nav bar to access my multi-window app.
I have tried flipping my signal cables, going from LP to KK, KK to LP, and reinstalling the firmware...
Edit: Whenever I factory reset in the stock recovery, I get an " Error:failed to mount /preload (no such file or directory)
Have you odin'd to stock lollipop?
You need to Odin stock firmware from Samsung, this will fix what you borked.
Then you can try again.

I've tried 2 fresh downloads of the stock firmware and it hasn't worked, but I will just download the file straight from Samsung this time to see if that could fix the problem. My new signal antennas I ordered from ebay are on the way and should arrive tomorrow. I'll then try that if this troubleshoot doesn't work because I don't have any 4gLte network at all, and it only pops up randomly and at certain areas I drive. I'm constantly moving and I could never have a stable connection, no calls, no text messages till I'm connected to the wifi:crying:
Edit #2: So I have installed new signal cables, and still not getting any 4G/LTE Network. I have constantly checked on my wires to see if it does anything to the network, but it doesn't. Still able to make calls on Wi-Fi only ): And I have used Odin to try and revert back to stock fully and no luck..
