[Q] Some cell problem (I9305) topic

Hello guys, i wanna ask..
Here's the thing, i've dropped my 9305, then it comes out making a problem, um.. it shows up emergency calls only.
So my phone is not my local S3 (i9300) ive got it from a friend. Can't go to samsung center, and then i've repaired it in some locals service center (unoffic), and the problems gone (RIL or data or cell network).
And now i flashed some custom rom, carbon and nameless. so the problem is in both rom it not reading my sims again..
My conclusions is :
1. the repair shop is changin parts not the one of 9305, maybe it's 9300 one.
Is there any workaround of this prob? i hope u guys can help me, thanks in advance.
And im just thinking. maybe i can flash 9300 modems to get my RIL back...
Whadaya think guys?
Will it break my phone?
Sorry for my bad english.

no cell service, sim not detected topic

Recently, when I would reboot my phone, or battery pull, or anything that turns the phone off, it will not have service, nor detect a sim when it turns back on. I could fix this by battery pulling and just putting the sim in ever so carefully and reboot. if it didnt work, id repeat until it did. Now, this doesnt work at all and i figured i needed a new sim card. Got a new sim but it did not solve the problem. anyone clues as to the cause? I hope the card reader isnt done for.

[Q] Xiaomi Mi2s - No cell signal after IMEI restore. topic

Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length :( (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.

I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???

Can anyone help me? I would appreciate it very much!!!!

[Q] Nexus 4 freezing when cell signal is poor topic

Hello,

I have recenly observed that when my Nexus 4 (running stock 5.0.1 Android) is left in an area where cell reception is poor, it would freeze: the power button will no longer turn the phone on, I would need to press it for several seconds to do a hard reset.
Yesterday the notification LED was still blinking when this happened. I have recently replaced the lcd assembly, could this be related? According to an app called Phone Tester, the proximity sensor is working.
Is there a way to make the system store some kind of log that could indicate why the phone became unresponsive? Thank you for all the support in advance.
