[Q] 3G very slow after update

Hi everyone, this is my first thread, I tried looking for the problem but was not able to find any information about it. I have updated the firmware on my I9003 from KIES the latest firmware is:
PDA: I9003DDLF2
Phone: I9003DDLE1
CSC: I9003ODDLF2
Firmware version: 2.3.6
Baseband: I9003DDLE1
Kernel: 2.6.35.7-CL1153545 [email protected]#1
Build Number: GINGERBREAD.DDLF2
now after the update I am getting about 70 Kbps download speed on my phone, I am able to get close to 390Kbps upload speed, before the update I could easily clock 2-3 Mbps on the same phone. Can you please let me know what I can do to fix the problem. My phone is not rooted and I have always used official ROM.
I have contacted my service provider, they are looking into it but I have a feeling it is something to do with the update because I have never had issue with this provider and it has always good speeds on 3G.

You might want to check the network settings. I think there is an option to use only 2g. Maybe that could be the issue. Do you get the "H" symbol when using packet data ? The H symbol is present on the left of the mobile signal indicator.

I have changed to GSM+WCDMA
Hi Thanks for the reply, but I have checked the network settings, I have been using 3G since 2005, I have tried all the network settings and even created new APN setting for Airtel, still the problem is same.
Any advice guys.

cellular network state disconnected please advise

I searched this forum and others and could not find anything that answered my question. If I am posting in the wrong place I sincerely apologize. If I did something totally stupid to my phone please tell me...here it is:
I have a text now moto g xt1032 with an unlocked bootloader, rooted, TWRP recovery.
I canceled textnow service and then flashed a rom (XT1032 Retail US Optimized v1.3) to get rid of text now's horrible rom that was preinstalled on it. This is not my DD and if I totally ruin it I can live with that but I hope that's not the case. I thought everything went perfectly.
I thought I might try to activate with TING. The MEID check said the phone was compatible (it did show an odd device name xtsomething instead of moto g) and they gave me a phone number and I believe my MSL but when I went to do over the air programming it wouldn't work because I can not enable data/cell network. It just says account could not be validated when I dial ##DATA#.
Sooo... should I try to find a way to manually program or do something here? Or is this because of my baseband/kernal?
My info:
moto G xt1032
android: 5.0.2
baseband version: msm8626bp_1032.390.81.01P BOOST_CUST
kernal version: 3.4.42-g6f35b04-00002 [email protected] #1 Wed Apr 15 11:59:10 CDT 2015
system version: 220.41.36.falcon_umts.Retail.en.US
Build number: see above
network type: cdma - EvDo rev. A
Voice: In service/data:in service
cellular network state: disconnected
Thanks guys for being so helpful and awesome!
PS will the xt1032 umts kernal be compatible with all of the above in case I need to do that?

You currently have a kit kat radio. According to the link below you should be using one of these for 5.02.

New Phone Software info Issue

Hi, everyone.
Just bought a new galaxy S7 G930F. I checked the IMEI info on imei.info and it says the phone was released on Feb. 2016. But when I look through my cell phone settings, I found the software info indicate:
Kernel version
...
Mon Jul 4 11:12:05 KST 2016
SE for Android status
Mon Jul 04 11:40:03 2016
Why is Jul? Shouldn't it be Feb? I'm not quite know these phone& software updating stuff. Does it mean the phone has been used before selling to me?
(I haven't linked to wifi or connect to networks since I started the phone.)

SE means security enforcing.. (correct me guys if i'm wrong)... in other words, it means that the latest security patch that was applied by samsung on your device is in july.

Hi mate
Imei are issue before the device is made , if you wish to know when the device was made and if it had a CSC change use an app like PhoneInfo
https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en

Thank you all for your help! Problem solved!
But one more question...
I did a little search about "CSC" (I don't know what the stuff is.......), and I found this:
Again, as the CSC of a Samsung Galaxy phone firmware contains the code-name of the country/region for which it is build, you can change it to tell Samsung servers that your phone is actually from a different country/region and get official updates for that country. It often happens that a firmware update is released for a particular country and you do not get it in your country. You grab the firmware file but are afraid that you will not be able to get the future official updates on your Android device if you flash a firmware that is not meant for your country.

The baseband version of my S7 is: G930FXXU1APEQ. It seems the baseband region is some European countries. I'm in the US, do you think it is necessary to change the CSC code?

It means Customer Service Code (CSC) and it provides specific configurations and software ( bloatware most times) for the designated region , most times is not big issue having a csc from a different region , unless you are having problems with the signal quality or you are missing an specific service from your carrier .
Anyhow G930F does not have a US CSC specific firmware as this model is the international model not "sold" in the US , you can change the CSC but you need to be root.
I would not worry too much

Can't get LTE/4G on Rogers S6 -> Fido

Hey all,
I've done the switch to VOIP and went with the fido 3GB plan.
I can't seem to get LTE on my phone but get it on my tablet with the same sim so its not the sim.
I've also already done all the basic troubleshooting such as switching networks, checking APN's, enabling LTE in the networks
Also when I try to do a CSC change to see if this would fix it *#272*IMEI* (whatever it is) I get 'unknown application'
Here is my device information
Model Num: SM-G920W8
Android V:5.1.1
Baseband: G920W8VLU2AOG2
Kernel Version: [email protected] #1 Wed Jul 8 2015
Build #:XtreStoeLite Deo Mod v2.2 - XXU2BOGG
Anyone have any ideas or need further info?
Thanks!

Rogers/Fido removed LTE connectivity from the S6 running anything lower than 7.0 according to a mass text message they sent out to subscribers.

Dunno. Maybe someone in your local arab community can generate an imei with an emmc gadget, if that's even possible. I've seen tutorials for older Samsung phones on YouTube.

Thanks that looks sweet hopefully another member could comfirm to us if its possible i appreciate the reply taught me something new honestly
