General :: Samsung S3 - Signal Connecting And Disconnecting After Flashing Rom?
Apr 14, 2014
So after flashing Cyanogen 10.2 on my galaxy S3 (which previously had 4.2 jellybean stock rom installed) I had no service and an unknown IMEI and basband. I went into root browser and replaced the current EFS folder with one I Had backed up a couple of days ago which was 100% working fine. after a quick restart the signal bar at the top has no signal for about 30 seconds then gets signal for 10 seconds.If I go into setting and phone status during the period of signal I have network 02-uk network type-hsdpa and my phone number stays unknown and my imei is being shown correctly during both signal periods.
I cannot find a similar issue anywhere else at all and as im fairly new to all this I'm completely stuck. I have a backup of my old rom (which wont flash due to status 7 error) I 'd rather keep this rom if possible though.

I noticed I was getting barely any reception after flashing cognition 2.2 so I used Odin to change back to stock. I still get barely any reception no matter where I go, and I'm not sure what the problem is. Any help would be much appreciated.

I want to reach out to others here before I take my Moment back to Best Buy to exchange it for another Moment.
My signal strength fluctuates wildly just sitting in the same spot. With the Hero I got a constant 5 of 6 bars, but the Moment will vary between 0 and 5 of 6 bars. But it's more complicated than that.
It seems that whenever the EVDO data kicks in, it causes the signal strength to drop to 0 or 1 bar. Once the data is idle, the EVDO indicator turns grey and then changes from EV(^v) to EV(D). At that point the single strength will return to 3 or 4 bars.
At times, though not as consistently or often, the EVDO connection will fall back to 1xRTT and will switch between them every few minutes. This will occur even when the signal strength bars are in the 3 to 4 range.
So, the my questions are...
Does the signal strength apply to the data signal or just the voice signal?
Is there any legitimate reason for the signal strength to vary wildly like I've described, even when sitting in the same recliner where the Hero had a constant 5 bar connection and data service that never wavered?
Is anyone else having signal strength and/or data service issues?
Should I exchange the Moment for another Moment or will I likely experience the same issue?

II am always having problems with pdanet and my fascinate. It works sporadically. When it does work it works great but most of the time especially at night i get usb connection dropped. It will for for a few sec then disconnect then reconnect. Is there a fix for this? Think it disconnected about 16 times trying to type this message. I could really use a fix as this is the only internet I currently have.

I have a problem with connecting my Samsung galaxy S3 (android 4.3) to any of my PCs. Before everything worked fine but then I upgraded to android 4.3 and connections started crashing. It still worked but connections were unstable. So I installed Samsung Kies 3 and from then on I haven't been able to connect my device to any PC. I tried everything I found on web. I have developer mode and usb debugging on. I know my cable is OK because other devices work just fine. Someone suggested going to usb settings but apparently there is no such think in android 4.3 settings, so I downloaded some apps to change my usb settings but they all require a rooted phone. I tried rooting my phone but even for that I need to connect it to a PC. I really need to connect my phone to PC to test apps(android emulator lags waaay too much).

With 3 different devices, an lg thrill, a nexus 7, and a Samsung infuse, over 2 different routers, a netgear and a Linksys with dd-wrt And using 3 different apps, twonkyserver mobile, Imediashare, and playto. Using any combination of above, why why why do the servers keep disconnecting after 45 minutes or so?
I've tried the keep WiFi alive apps and they dont solve the problem.

After connecting my phone by USB to PC and transfering some files to SD card and then disconnecting, i'm getting error "Application not installed" on some apps installed on SD card (for example Adobe Reader, Temple Run 2). The only way i figured out to solve this problem is restarting my phone... I don't want to restart my phone nearly every day, just because i needed to connect by USB cable to transfer some files....
Phone: Alcatel One Touch Idol 6030X, Android 4.1.1 - official, not rooted.

II would like to flash my Samsung Galaxy 3 (right now Froyo) to use it with Kyrillos' ROM v7.5 under Mac OS Lion.
The only program capable of that I found (in this forum) is the Wineskin'ed version of Odin (v3 1.85). But that does not detect my phone in download mode and also has other buttons than the version Kyrillos speaks of in his manual (there you are asked to "select ops", while the Mac version of Odin only lets you select "PIT"s or chose a .tar-file for one of "BOOTLOADER", "PDA", "PHONE" and so on).
So, three questions:
1. How can I get that version of Odin to recognize my phone?
2. What do I have to select in that version of Odin after solving question 1?
3. Otherwise, are there alternatives to use (except a Windows computer or a virtual machine running Windows)?

We have an S3 Mega, started using it as a Wi Fi access point for a Gateway Desktop, Windows 7. After 8 hours of flawless operation , the usb starting disconnecting and then reconnecting.The check box in the settings screen for USB tethering would uncheck. If you rechecked it it would connect then disconnect and uncheck the box. We moved from a front USB port on the Gateway to a rear USB port and that fixed that problem but after overnight, no WiFi access. Rebooting the computer fixed that.

I got a problem with my T10. Whenever I'm doing something that uses WiFi, I keep getting D/C'd. Its not my router, because I have other tabs in the house which are fine. WiFi sleep policy is set to Always Keep On, and I've tried apps like WiFi Keeper and WiFi Static which don't work.

I have recently upgraded and rooted my Grand Duos i9082 (currently on Stock v4.1.2 AMB3), and was browsing through the "Root Explorer" app, when I noticed some folders under /mnt/ and /storage/ listed as UsbDriveA, UsbDriveB, UsbDriveC. I can connect a USB Flash drive to my phone, and use it as an external storage media? I believe this function is available on Samsung Note & S3 as an inbuilt function (i.e. without having to install any external application). I would like to know if the same function is available on my Grand Duos.

On my Samsung galaxy s3 I have 2 flashing arrows under my wifi bar.. I went to Samsungs chat and the first time I was told that it was because I was transfering data but I wasn't. She then told me to do a soft reset so it did and it still continued. Then I went back on because the first person told me it would eat up my data if I didn't break the transfer. The second lady said that all that means is that it's showing that it's connected to my router and is normal and won't use my data..

how to change the icon of its battery, WiFi and signal bar. I was able to successfully root the phone..I wanted the phone to look original by changing those icons. Even if i try to apply different themes those icons wont change. And another problem is Phone Coverage Signal weak or lost, another phone can receive 50% or full coverage signal.

My Samsung Galaxy Reverb has nobody willing to build CM10 for it, so I decided to take on the task. It built without error - processed the kernel and all the CyanogenMod 10 files just fine and generated the .zip. However, after flashing the .zip I end up with a Samsung logo, then a black screen.
The compile went through without error, so I'm a little lost as to what I should check next. From doing a little searching it seems the kernel is at fault, but what to do about that. Am I supposed to flash the kernel separate from the .zip that the CM builder outputs?

I have an app that was installed via Android Market. And so, the Android Market knows when new versions are out and notifies me of an update. Titanium Backup calls this the 'Market Link', not sure what else it could be called.
how would I go about 'disconnecting' the app from the Market? Deleting the market link as if it were side-loaded?
Yes, I know this means no more updates for the app etc. Which is actually what I'm after.
I'm using a SGS - DocRom V9.6 with Speedmod Kernel k13a
