HI, I have issue since I flashed latest AEX Oreo rom (01-17 build). I get no LTE, only H+ or edge. I tried various baseband and select network manually but it doesnt work. If i try to flash baseband from ZUI 3.5, the unlock battern on boot doesnt work.

Hi, i have a big issue, i install any custom rom, pac rom, cyanogen unofficial, cyanide, etc... and have the same problem, the wifi connects the first run, but after the reboot, cannot connect and stay in "saved" or "obtaining ip address", my bootloader is: I747MUMUEND3 and my baseband its the same; any solution? or any tutorial for the mexican network?
You're running a 4.3 modem and bootloader which is outdated for some the most recent ROMs.
You need to update the modem and bootloader.
Hi i installed latest cm13 nightly..but i am unable to change data network type from settings...can someone help??
I am on latest sense MM firmware 6.12.1540.4
Good morning, I am running the latest Lineage 14.1 rom (14.1-20171204-Nightly-d2att) on the Samsung Galaxy S3 (SGH-I747) phone, this phone is rooted, running the latest TWRP (3.2.1.0) and the I747UCUFNJ2 baseband on this device, this device is fully rooted, and is SIM unlocked for use with any carrier, my carrier is T-Mobile.
Ever since installing this rom, and any roms higher than android 6.0 (I've ran CM 12, CM 12.1, CM 13, SlimKat, and AOSP roms), everything works perfectly except for my cellular data will not go higher than Edge (2G) and my complete cell connection will randomly disconnect for a few seconds then reconnect itself.
I've tried everything from changing the APN settings specified by T-Mobile for LTE connectivity, I've gotten a replacement SIM from T-Mobile, I'm lost at this point as to what the issue could be. According to T-Mobile I do have the BYOD option so unlike some carriers, the SIM is not supposed to be locked to a specific IMEI.
Does anyone have any idea what could be the issue and/or a solution to this? Is there a higher baseband that needs to be loaded to fix this that I'm not aware of?
Thanks for your help everyone.
The phone is also running the latest bootloader?
Yes it is.
I assume the cellular data works properly with a stock ROM.
Does the cellular data work with the sim in another phone? Cellular data works with another sim card in the s3?

I updated to oreo firmware and lte gone. It would only show 3g where as i am in full lte coverage zone
I flashed different oreo and pie roms but fruitless
I tried to fix by erasing modemst1 and 2 but it always give error of 35 partition
Today i downgraded to Nougat and erase persist but it is still same
i can only get 3g no 4g or lte
I tried network reset by ##72786# but it eventually sim locked my phone and i had to unlock it manually
Any suggestion or possible fix
Thanks in advance
did you find the answer?
I have also lost connection. Except mine is both 3G and 4G. Oddly I can still call, text, use wifi and putting the sim in my other phone works just fine. I have no clue what's wrong. I've tried everything at this point.
Here's a link to my thread if you wish to follow any solutions provided if someone comments.

It had same situation but eventually I solved it. Now LTE is working. First of all, need to be S-OFF and then after unlocking SIM, you can install any firmware with any ROM that supports the encryption...Either US unlocked or UK International Roms will fix the LTE issue. One thing to notice: you must keep the data partition unformatted for keeping the SIM lock status and need to use SPRINT or VERIZON radio. I am using stock Oreo from with Verizon radio + Magisk.
In addition, I unlocked LTE bands as well with DFS Qualcomm tool
