Hi,
I have Lenovo A820e which is CDMA + GSM phone.
I am unable to switch on data either on CDMA or on GSM. However, the phone is able to use wifi.
I have saved the new APNs for Relaince CDMA and Idea GSM. But to me, it seems that China Telecom is preventing data connection other than its own.
How can I solve this problem ?
Plz. help.
A820e
Hi, I have also an A820e. Got to the same point. I've installed a ROM with GApps and got everything working except I can't get 3G data, only GPRS.
I think it's ROM related.
Have you been able to find a solution?
It seems that Lenovo A820e doesn't have the 2100 band which is required for 3G communication in Europe.
The way I was able to activate data in the ROM that has the google services is by introducing the following code in the dialer:
*#*#4763#*#*
After this a message telling me that the data has been started appeared and I was able to control.
Also before this I made a change in system/build.prop
to default the network to gsm. I've added:
ro.telephony.default_network=1
(Should be rooted to have access to this. I've used Root Browser)
Hope this helps.

*#*#4763#*#* - did not work for me... It seems it depends on ROM

Which ROM are you using ? Can you give me the link ?
Hello everyone. I have the following question regarding my SG4 device. A while back I configured my sprint phone to use it on T-Mobile HSPA+ bands. I remember following a post (not sure which one it was though as it has been a while) here on XDA for the initial configuration that involved downgrading the modem and then changing some config values. I am trying to return my phone to its previous state; basically want to get return the config values and the modem version same as it was. Can I accomplish this just by installing the stock ROM? Or do I need to go in a put the previous values first? If there is a post out there for this any reference to it would be so helpful for me.
I appreciate the help in advanced! Thanks
UPDATE: this is the post I followed for the initial config. http://forum.xda-developers.com/showthread.php?t=2530610&page=136#post57903485
My device is intl unlocked by sprint customer service but I cannot connect to carrier network. I am suspecting is because of the settings or perhaps the network control setting described on step 8 pasted below? I am OK with losing the domestic unlock settings.
Step 8) Press menu and back twice, you should be on the PHONE CONTROL menu. Select [7] NETWORK CONTROL, select [1] GFC and make sure that it is set to [1]GSM/(E)GPRS/WCDMA REL8 .
Hello
I am using verizon sansung s5 900v on a network other than verizon. I wanted to know whether i can activate the hidden codes without rooting my set. Further is it possible to use other network 4g on this set. I have heard that i can only use other network 4g if i can enable hidden codes. I dont want to root my device. Any help would be highly appreciated
I may be wrong, but im pretty sure enabling them requires root. So to answer yout question, no you cannot without rooting.

I don't think you need hidden codes just to use another network. You just need to input the correct APN for mobile data. Now, if the codes provide functionality to recharge on that network, etc, then you won't be able to. You can simply root and change the appropriate setting and unroot and it will stick, since the setting is in the EFS filesystem of the phone.
You only need to do step 2 from the OP here after rooting on the S5: http://forum.xda-developers.com/showthread.php?t=2303905
FWIW, I was recently in Puerto Rico and was able to buy and use a SIM card with 4G data just fine on my Verizon Galaxy S5 after inputting the correct APN information and selecting GSM/UMTS as the network or Global instead of LTE/CDMA. Verizon's handsets are usually unlocked by default.
If you have the latest software update, band 4 should already be enabled, barring there is some sort of SIM check to determine if there is a VZW sim card installed, but I doubt it.
if you have a problematic firmware that won't allow you to edit your APN settings in the dialer hidden menu, this may be what you need.
first, the warnings:
1. THIS IS ONLY FOR SPRINT SAMSUNG PHONES RUNNING TOUCHWIZ ROMS!!! never attempt on any other carrier or manufacturer's device or alternate roms! it should most likely work on other Samsung Sprint devices with stock/touchwiz roms.
2. DEPENDING ON DEVICE, YOU ARE MOST LIKELY TO BE FORCED TO FACTORY RESET YOUR DEVICE IN THE PROCESS, which likely includes LOSS OF ALL DATA ON INTERNAL SD!! take all necessary precautions.
3. ROOT REQUIRED
4. you will STILL NEED your MSL number!!!
5. have a FULL backup in TWRP ready in case anything goes wrong. INCLUDE your EFS in the backup!!! again, INCLUDE YOUR EFS. make sure it's stored on EXTERNAL sd card. again, EXTERNAL SD CARD!!! or copy it to your PC if you don't have an external card.
here's the short but sweet guide.
1. download "Samsung Phone Info" from Google Play
2. swipe over to the CSC section.
here you should see:
Firmware's CSC Code
Active CSC Code
Available CSC Code
3. if Firmware's AND Active both say XAS, you should already be able to edit your APNs using your MSL number.
if Firmware and Active codes do not match, you have a dirty rom and I am unable to help you correct it, you'd best try a different stock based rom or 3rd party that allows it by default.
if Available CSC Codes does NOT include "XAS" then whoever modified the customized stock touchwiz rom you're using removed it and you'd best try a different stock based rom or 3rd party that allows it by default.
4. using any CSC editor, change "SPR" in ALL places it appears as only the 3 letters "SPR" to XAS
5. confirm changes and reboot. you will now most likely lose ALL personal data on your phone and should now be able to edit your APN using your MSL inside the dialer's hidden menu.

Have you found a way to retrieve your MSL without calling sprint? I've tried all the tool apps in the play store and using a logcat within the ##3282# menu with no luck. Getprop ril.MSL yields nothing, not even a not found error.
I've tried calling sprint for my MSL but refuse to release it.. I'm not exactly on their "nice" list - they've even called to tell me I'm "using too much of my [UNLIMITED] data" many times so I don't expect much from them anymore..
Any help or direction would be greatly appreciated
try the Sprint chat -- through the website, NOT Facebook, and have a good reason ready as to why you need the MSL, other than for bypassing their security lol
Holy **** after searching high and low I have FINALLy found a way to get back editing my APNS for hotspot on my rooted Sprint Note 5! AND I keep Android Pay! Thanks so much!!
This works perfectly! Only thing is turn on hotspot option disappeared from settings. I can turn it on and off from the top bar if I swipe down. OR I can download a hotspot shortcut app and access it from that app.
Also I noticed my icons for LTE now say 4G and the bars are different too - more old school.
I noticed I changed EVERY SPR to XAS - do ALL of them NEED to be changed to enable APN editing? Can I switch back the ones that give me back hotspot option in settings and stock LTE & bars icons?

this **might** be fixed by renaming (or deleting, if you're brave) the features.xml file, if I remember correctly, stored in system/csc/ or system/etc/ not sure honestly
features.xml.backup should do just fine.
if the rom doesn't boot afterwards or if the dragons catch all your apps on fire, go back to recovery and use TWRP's file manager to change it back
also, any xposed app (like wanam's) or other feature.xml adjusting apps (like GalaxyTools or Samsung Phone Info) can cause the problem to happen again.
the alternative / temporary / dirty-fix would be to create a shortcut to hotspot on your home screen:
1. download Activity Launcher from Google Play
2. launch and change recent activities to all activities
3. wait approximately 72 years for it to load
4. scroll to Settings and tap it
5. scroll to Hotspot and long-press it
6. tap create shortcut
7. never uninstall Activity Launcher -- instead just make it a hidden app (it's very small anyways)
I can just longpress hotspot toggle in slide down drawer from top no probz. Which CSC settings modifies the ability to edit APN? I want to put the rest back to SPR.

I used the msl code and everything appears the way you say it should... but the phone STILL says invalid sim!
What internal file must be deleted, the thing is unlocked on sprints end it just wont let go !

Hello,
I rooted Sprint Note 5 from Nougat to Magisk and went ahead to replace SPR into XAS in all files under system/CSC folder. APN Type is still coming greyed out. Any help will be appreciated.

Hi,
I have a T585C with Android 6.0.1 (version=T585CZCU2AQH2). It seems the well known secret code (e.g. *#...) doesn't work anymore on it. I can enter the Service Mode using Shortcut Master. But I prefer to not using any third-party tools. Anyone who can help me?
Another question is: is there a way to reset all settings in Service Mode? The "NV Rebuild" function seems to have no effect... I did some changes previously. But I'm not sure if they have been all set back to their original values...
Thanks!
regarding the reset settings. I found a simple way that just use the nv_data backup file to replace the current used one in /efs partition.
but still have no idea how to enter the service mode via a graceful way...
