For the life of me I can't figure out what I did wrong. I purchased an Oppo Find 5 from China, rooted and flashed some custom ROMS. Somehow something screwed up my cellular connection. I get no service at all. I've flashed different roms, modems, factory reset ..you name it without success. The SIM card is detected but can't make calls or get data. Any ideas?
Edit: Problem solved: flashed a modem for x909t and now have service. I've been flashing x909 modem and that was the reason for connection failure.

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!!!!:crying:

Hello,
did you have some informations ? I have the same issue with my MI4... No more network after a flash of CM12... I hope you found a solution.
thanks.
My vs980 has no signal and i cannot change the network mode from GLOBAL in settings. I was previously on an older unofficial cm13 with working tmobile service, then i stopped using the phone and came back to it a while later and flashed the latest crDroid nightly (12/12/15) and never looked at the phone again until now, when i realized there is no signal.
I have tried different inactive Verizon and t-mobile sims, yet the phone still says no service emergency calls only, and network is stuck on global. I have tried a modem and efs restore through twrp, and even flashing back to stock to no avail. The phone does have an imei still, which is a good sign however i am all out of ideas for fixing this.
Try flashing stock KDZ. If it won't help, then very well could be hardware failure.
Try flashin stock kdz (maybe your imei has been deleted) ( and sorry for my english?)
Hi, I'm having a very perplexing issue. For the last few months I have been running cm13 on my phone but recently it decided to not revive/send texts or calls but still got 4g and signal. I hadn't updated the rom or anything so that wasn't the fault. Looking at the sim card info in the setting it says it's in service and everything, but says the "cellular network state: Disconnected". I've reflashed to a touchwiz rom and everything worked fine. So far I've tried different cm roms clean and dirty flashing, flashing just the modem on to the cm roms, restoring from old backup before all this, replacing the sim card. For awhile I though it was the APN settings weren't right, but the cm apn settings matched the TouchWiz ones. I've also tried different unbootlocking methods, didn't help. Worked with an unlocked bootloader running touchwiz. My brother has been running the same phone and rom I was and hasn't had any issues. I'm out of ideas on what's causing this right now, hoping some can help.
Had something similar happen. Try changing the APNS till you get a single
Changing preferred networks might help too

Hello,
I have an international version Nexus 6p. While I was in Panama I accidentally removed the OS using TWRP, after rooting. I reinstalled the latest OS, TWRP, root, and used a custom ROM. I was dumb and didn't back anything up.
I couldn't make phone calls or access the internet with my phone on the network I used there, but I could with WiFi so I chalked it up to the ROM. Removed that and did a fastboot factory reset. I still couldn't make phone calls or receive them so I figured it was the network in Panama.
When I got home I still can't make or receive phone calls. I can text, and access the net but the service is very unstable. I am using cricket wireless, and I know it's not the service because the Sim was in my gf's iPhone and worked perfectly, and my friend has cricket and his is stable and works perfectly. I am running the latest Android 7.1.2 and would love some help with this issue.
I have tried flashing a new factory image, erasing modemst1 and 2 through fastboot, changing bands, using a different Sim card, factory resetting in general.
I have not tried another ROM (read somewhere that chroma would fix the issue, but don't really wanna jump back to 6.0.1 unless I have to).
Thanks for any help.
