Any suggetions that can Help me?
Thank you!!
@autoprime ?
i have samsung i337MVLUFNE1 4.4.2, now the problem is i have no idea how to unlock i used to know that one way where you unlock your phone with the hidden menu and it's not working anymore.
I never seen FNE1 here is it different ? i dont know which modem is this can you help me out and tell me which modem does it has and can i do it for free or i have to buy the code?
Thank you everybody in advance for the help you may provide.
Please could you help me to understand if i can fix my scl23?
This is the thing.
I got myself a KDI au gs5 scl23 with kitkat 4.4 and as i understand its rooted with a custon recovery, beacaus of the sim unlock, and the recovery its in japanese.
The phone works fine, but when i try to use it on ultra saving mode, its says that it`s samsung account isnt activated and doesnt allow me to change it(in the settings of the phone there isnt a way to change samsung account). So it bugs on that samsung account, and doesnt allow me to use internet and the keyboard when im on the ultra saving mode. By the way i live in Argentina and cant find anyone who speaks Japanese.
So, Trying to fix this samsung account problem i upgraded to lollipop 5.0, but it lock the phone and it doesnt get any antena signal, its says insert a sim, but there is no "no sim" mesage on the mesage board.
And now im dowloading the 4.4 firmaware files to downgrade it to 4.4 and to unlock it whith service menu commands.
Have anyone been able to unlock it with service menu on lollipop, or in any other way? Beacuase lollipop fixes the samsung account problem but olso locks the phone and installs custom AU rom, only in japanese or english laguage.
Thank you very much to everyone.
same here
This is the same thing that happened to me, did you manage to revert back and unlock the simlock on 5.0? Any luck upgrading to 5.0 and using your sim with the device.
cheers

Ended up downloading the 4.4 rom for phone again, installing that. Had to clear cache and do factory data clear to get phone booting again after downgrading. Then I was able to complete the Sim Unlock steps outlined here

Super frustrating using a phone like this, as it has so much bloatware from Japan which I just want to get rid of. But up and running now, with several replacement mods for keyboard, messenger etc
A lot of information out there, thank you internet and forums like this one for having so much information to get things working again. :victory:
Hello Techies
On Christmas Day My Redmi 3S Prime gave up the ghost , the Mobile radio refuses to latch onto a 4G Network and can only reliably make a call when a GSM network is selected . This seems a pretty common bug , though I have scoured the solutions ( which seem to work for others ) ; swapping to multiple sims/providers , manually setting APM and Factory Reset , though the phone barely connects to 2G/ Edge Technology . This is a huge inconvenience as I use the phone for both business and personal life - not being able to use it is a royal pain in the ass .
I have contacted Xiaomi who recommend flashing to the official developer ROM Version: 7.12.21 (MIUI9) . I currently have latest MUI Global ROM (8.5) I have tried updating (downgrading ) to an earlier build (8.1) - using the 'upgrade' app on the phone , however this would not work , the device said it could not update to an earlier build . However I will try the developer ROM next , which I guess should work ?
The other option was the fastboot upgrade , which allegedly allows the phone to downgrade to a previous version ( I wanted a stable ROM , I dont really need Dev ROM ) . However the instructions are extremely vague and were written in a different environment (for earlier MUI builds and WIndows 7 ) . When following the official 'Fastboot' flash guide , it transpired that 'download mode' did not work with MUI 8.5 - so it seems the guide is irrelevant
Bottom line currently I am lost on what to do next . I will try the DEV ROM and see how that goes I guess .
After some reading , I am of the understanding that my Bootloader is locked ? I had purchased the phone with the official Global MUI rom installed and have only updated it with OTA official updates previously . I did not want to unlock the bootloader as my banking app (Barclays ) will not install on unlocked devices. I understand unlocking the bootloader also roots the phone .

Try flashing the phone in edl mode. I don't think it needs bootloader to be unlocked to do that.
For procedure you can refer Google
Update:
I did manage to update to MUI global 7.12.21 Beta using the Stock updater app . However this did not fix the issue , the phone still connects just with GSM and Edge Networks . I tried all of the existing configuration solutions after the update , which also did not resolve the issue .
I also contacted the Xiaomi Outlet on Aliexpress , they suggest that I unlock the bootloader , as per the email they had sent me
Thanks for telling us the troubles you met. Do not worry. We are here to help you.

My gut feeling is that this is a hardware issue , it seems as though the radio reciever has burned out . I have already flashed with the native app . Is it worth trying to unlock the bootloader and reflash another rom ?
I dont want to waste any more time on this , any suggestions or thoughts on this are appreciated
So the reseller is asking me to unlock the phone though the Mii Unlock App , then flash it .
How can this make the 4G radio come to life ?

If you really feel it's a hardware issue, then it's recommended to claim the warranty or replace. I'd suggest you not to go with bootloader unlocking at this stage

Also, ask the mods to move this thread to question and answers section.
Try *#*#4636#*#*
Than choose Telp Information1 >> choose type "LTE/WCDMA" or "LTE Only"
Hello
OK I made some progress , I changed the sim Card to an O2 Network Sim which works perfectly . I had tried exhausted all other practicable solution given including the above . This doesn't explain why the phone stopped working with all EE network providers ( tried Virgin , EE, Plusnet ) .
http://en.miui.com/thread-1429676-1-1.html
How can I find out which bands a sim card provider is using ( Live Information ) . I have tried to research this but bands have changed over the years , so not sure which provider is using which band . I wanted to determine which bands the phone will currently work on .

You are on QJ3? If so, you are out of luck at the moment.
