Does you need to install lasted firmware before to install the rom?

My internet data frequently disconnected

Hello,
i am back again with a new problem!
All the previous problems that was mentioned in this forum is GONE. i was a happy owner. Until i got this problem.
so i wanted to try new Modem, just so i can increase my Signal, and right now, my data plan is keep going on and off, and most the time i can't get it connected it.
i did the wipe date /factory reset from the ROM manager, and wipe cache and dalvik. and yet the problem is not solved.
right now, am running cm-10.1-20130304-EXPERIMENTAL
and the Modem am currently running which sometimes works ( I747MVLDLK4 ) am with Rogers, Canada, Edmonton, AB
If anyone helped me out with this, your next coffee is on me! for real!
anyone?
When I have Wifi or Signal/Data issues, I just Odin back to stock and then re-root & flash ROM again. Works every time.

Did you use ODIN to flash the stock ROM and factory reset in stock recovery ?

Yes! i think i did a mistake. While i restored to the stock rom, The baseband that i was using it was I747MVLDLK4 and not the STOCK modem. So maybe that is why its not getting connected? am trying to apply the stock modem into the the stock rom, but its giving me Fail error.
am just scratching my head right now to be quite honest and this close to throw my cellphone outside of the balcony.

What type of fail error?
How are you trying to flash it?
i managed to make my modem into the stock version. However am just getting "E" in my data connection. Reminder am still in STOCK ROM and stock modem now. is that a good sign that i slighty getting everything back??
should i just install the CM 10.1 now and see the results or what you guys recommend?
annnnnnnnnd my " E" is gone.. Beautiful
do you guys think it might be a actual physical sim card issue?
UPDATE: i restored my phone into the stock rom by Odin3 and now i just re flashed the Cm 10.1 again. sadly i still have no connection and my income and outcome for calling and texts is also not working.
please help!
Try flashing Task's AOKP and see if you have the same issue. Additionally, try deleting the current APNs (access point names) and manually enter the APN settings for your carrier. Could also just be a faulty SIM card as you mentioned.

[PROBLEM] 3G Doesn't Work!

Hello everyone,
I currently have an issue with my arc S (LT18i) where 3G doesn't work anymore on any Sony stock ROM. I am aware that my carrier supports the needed basebands, and I am in an area where my service has 3G with full signals. I have tried the following:
I have switched ROMs from ICS and Gingerbread & tried reflashing, but still 3G doesn't work. I have no problems with 2G however.
Changing kernels didn't help too. I normally use LuPuS, but the problem still remains.
I first thought it was a hardware issue, but then I switched to CyanogenMOD and MIUI, 3G works on both ROMs. So it's not a hardware issue.
I still do not know what the problem is. Can anyone help me out? This problem occured just after I flashed LuPuS kernel, and then returning back to stock kernel. Ever since then 3G doesn't work.
Hope I get a solution. Help is appreciated. Thanks!
Did you flash the correct baseband for the ROM? Each Android version works with a different baseband.

Never had problems with using various basebands on various ROMs. 64 worked fine on ICS, 77 worked fine on GB. No issues for me.

I used what comes in the .FTF itself. I even tried flashing with Sony's official flash tool for unlocked bootloaders. I'll try manually flashing basebands and switch them out to see whether that works.

Gotta check then.
Had you checked in what mode are you?
2G, 2G/3G Prefered, 3G only
Had you configured the APN Settings? In my phone it doesnt donwload anything from 3G/2G until i register the network.
Or perhaps you didnt do all the wipes and some remanent file is causing the problem.

Residual files seems to be the problem. I have the correct APNs and correct mode. I should try clearing with fastboot.

Flash a new kernel and do clean install, wipe everything and flash a ROM.

Wiping everything off and flashing a new kernel and again wiping and going back to stock ROM worked.

Personally, I would flash in this order:
- latest LOS 14.1
- firmware
- gapps
Then wipe cache and reboot.
I assume you're also using the latest twrp?

my problem was a little bit different but it might help you. my wife and i are using mi5s 4/128gb. and we bought them from same website. we couldnt be avle to connect the same wifi in our house. i tried many different custom rom or stock rom but it didn `t solve it. i guess the person who sell the devices , put the same mac adresses to both device. so i figured out the problem with changing the mac adress. Now our devices are connecting any wifi hotspot without a single problem. :good:

My modem files erased when I did root my phone. Modem files need to write again. This is only solution . I will try to write modem files. After that I let you know.
TWRP backup so important, this case. Modem and other files must be protect with back up.

My modem files crushed. This files wrote again and phone back normally.
Back up files need to be archived before flash rom.
