Help please? - Xperia Z1 Compact Q&A, Help & Troubleshooting

I bought my phone from Japan and I am herein the Philippines and I noticed recently that when I am connect to mobile data, the logo shown is "R" meaning roaming, no 3g or lte appearing. What must I do to remove it from roaming? I tried turning roaming off but i can't connect to internet. When roaming is on only R and no 3g icon, even if mobile data off the R icon is still present.
If I am to root this or flash to remove docomo software, what must I do then? Please help

flash guide
On Z1 board, there have a guy who bought a JP model of z1 and he tried to flash a HK firmware to replace the JP rom and fix the LTE problem and works. So, I think you can try but I don't promise, make sure your phone is not sim locked.
And there is two z1 compact of JP models available in JP. The old one is Z1f(SO-02F) and new one is Z1 A2(SO-04F). I think there is no different, SO-04F just got more color and the camera software supports 2K recording(but still no 4K ...lol).

It's just a suggestion but a more descriptive thread title might get more responses...

I hope that it will work. I haven't tried rooting and flashing before so I am a little scared about it. But i don't see any ways to do this. Thanks a lot man!

[Q] LTE SIM inserted, but "Insert SIM Card to access Data Services" message shows

[Q] LTE SIM inserted, but "Insert SIM Card to access Data Services" message shows
Hi,
I'm in the Philippines. I bought a Note N7105 last week (not from my provider) and installed 4.1.2 with baseband N7105DXDLL1. All good until a few days ago I received my LTE card from GLOBE Telcom.
Now I have a problem. I can make calls and send SMS using the card but when I try to enable data services it tells me "Insert SIM Card to access Data Services", and will not enable data or let me see anything under "Mobile Networks".
I have tried a different Globe LTE SIM card (my son's) and the same thing happens.
If I put this LTE SIM into my Galaxy S II (Baseband = I9100XXLPX), it runs fine (but 3G of course). So it's not a faulty SIM card.
I was wondering if the problem might be the modem ? Any ideas ?
Globe runs LTE Band 1800
thanks
Could it be the modem ?

Have you try changing network mode under settings - wireless (more) - mobile network - network mode
If you set it to utms/wcdma doest it works?
(Sorry I just assuming and here in India we don't have lte and never seen menu of mobile network in lte version)

When the SIM is inserted, the whole mobile settings menu becomes unavailable, because the phone thinks no SIM is inserted (even though calls and SMS works).
UtkarshGupta suggests its the APN not the modem so I'll look into that too.
For now, I have a new problem - the SIM slot is broken, due to using one of those stupid Nano adapters, because my provider does not have micro SIMs. So until I get that replaced, I can't try anything !
Re: [Q] LTE SIM inserted, but "Insert SIM Card to access Data Services" message shows
Yeah could be modem as well

Hi
I'm from the philippines just as you. I'm also using globe's LTE and recently have bought a note 2 (N7105). My note 2 works perfectly. But a few days ago, my friend who was interested in getting the same phone that I have, decided to buy one. We went to the same store hot gadgets to buy another phone exactly like mine N7105. We encountered the same problem as you. All other simcards would work except for my Globe LTE sim. It seems like its a new batch of note 2s from their supplier abroad. What i noticed about the new batch that arrived is that it was previously locked to a foreign network and just unlocked. the box also has a "cityzi" logo which is a carrier in france. the seller claims that all their units are locked and just unlocked.
but i believe that the batch i got was factory unlocked in the first place because there is no logo on the box and no logo when starting up and turning off the phone.
I have a feeling that it may be a firmware related problem. what i would like to ask if you have tried updating the phone to the current DMC3 firmware. you can read up about it.
there is a forum on tipid cp on n7105 sadly im just a new user on xda so i cant post the link. just search for it.
if you check sammobile.com there is an n7105 firmware for the philippines. im not sure if flashing it with this new firm ware would fix the problem. i flashed my phone with it and it worked fine but im not sure if a previously locked phone would create problems when updating firmware. maybe some people in the forum could help. thanks.

Hi, Yes I flashed the firmware N7105XXDMC3_N7105OLBDMD1_GLB and now my note 2 works fine with Globe LTE. I found details on this site http://wccftech.com/update-galaxy-note-2-lte-n7105-xxdmc3-android-412-jelly-bean-official-firmware/

This is an English only forum. Ask in English if you want an answer. Also, this section is for the Note 2. Ask again in the S3 section, in English.
Worked like a charm. Thanks!
big thanks to this thread! i had problems with my N7105 from HK as well but now it works fine on Globe LTE!
only problem i encountered was downloading the file which was 1GB, kept failing to download until this morning hehehe. :highfive:
Hi everyone. Might there be a torrent for the firmware file? Download keep terminating on my side. Thanks guys
Hi!
First I want to thank you for pointing out that only XXDMC3 will work with GLOBE LTE.
I think it is the SIM card itself because I have an AT&T i317 Galaxy note 2. First I wasn't able to get it to work. Same issues with you. Can call, text, but will not allow me to access mobile services.
I also tried flashing it with the modem from here (XXDMC3 (Philippines / Globe) N7105DXDMC1_modem_GLB) you can use this modem if you have the N7105
I misread the instructions and had a bootloop. But was able to reflash the stock AT&t firmware.
So instead of going that route, I downloaded this International ROM for ATT Galaxy note 2 As it is already XXDMC3 baseband.
It works very well. But I still have to wait for the activation of my LTE to see if that really works. But now I can access the menu's and H+ works on my phone.
This is using the Stock AT&T Modem.
I hope this helps folks with international phones and want it to work with GLOBE LTE.. =)
This firmware works fine with globe, but not so sure about Smart. A Smart prepaid SIM works fine, but a postpaid SIM does not work at all, not even for calling / texting. Smart are unable to explain why this would be the case. They made up some BS story about the phone being locked to Globe (a 7105 International edition !!) I was not able to test it fully because I sold the phone, so I can't say for sure it was a firmware issue. But we tried several Smart postpaid SIMS and all did not work. Just throwing it out there.

[Q] How to activate LTE bands on Z1C?

I bought a second-hand unlocked Z1 Compact which seems to have been sold originally by Virgin Mobile UK.
When I'm in the UK I use it on the Three network with a PAYG 4G sim. It picks up 3G/HSPA+ all over London just fine but I can't get a 4G connection at all.
In my network settings I can choose WCDMA only, GSM only or WCDMA/GSM. There's no option for LTE. I'm assuming this is a limitation of my ROM. I recently received an OTA update to 14.4.A.0.157 but it hasn't made a difference.
Is there something I can do to unlock the LTE bands, or should I flash a generic (non-carrier) UK firmware?
1. Assure your plan covers LTE. Check your SIM in other phone which can do LTE connection.
2. For myself - I knew I had plan with LTE and phone was capable to connect it but when I made 'connect LTE only' in settings - I got message:
"Your SIM card refuses to connect this way". That explained a lot.
I had to change SIM card to LTE capable and all of the sudden I had LTE.
I had the same issue when I first bought mine. It was a generic uk device but missing the 4G option in the settings. An upgrade of firmware solved the issue for me. If you know your plan and sim support 4G I would suggest trying the generic firmware.

Thanks - according to the network you don't need to do anything special to activate 4G/LTE on any Three SIM.:
http://www.three.co.uk/Discover/Bui...230&gclid=CPG49de_p8ICFQpMtAodWkoAYw&aidset=1
When I took the phone to the Three Store in Islington the guy looked in the options and told me that my phone didn't support 4G/LTE as there is no option for it the settings. However both the box the phone came with, and the device itself (in the service menu), list various 4G bands as supported. They wouldn't really help any more as I didn't buy the phone from them.
The only other devices I have to hand are an iPhone 4G, a Samsung Galaxy S2 and a Huawei Y330, none of which support 4G. Also the only 4G SIM card I have with me right now here in Portugal is one for NOS (Portuguese operator) and I'm not sure it will work in a phone as it is designed for home 4G broadband.
I'm willing to have a go flashing a UK unbranded FTF, but I can't find one anywhere with the 157 update.
EDIT: I just figured out how to use XperiFirm and it seems the ROM I need isn't out yet. Might not be ready in time for my next trip to the UK but fingers crossed.

You can get latest firmware and baseband, it doesn't have to be for your country or provider, head over to IaguCool' s thread on Xperia Firmware Downloader & Checker. Follow the instructions there.
You will need a copy of Flashtool and it'd be good to read the thread on 'how to' as all the instructions are there, rather than jump to the last page and ask, which is what everybody does.
This will deliver you the latest stock build, bootlocked and not rooted, so what you do with it after that is up to you?
When you first start the phone it will go through setup, where you get to choose language and provider. The only thing you might need to know is your service providers APN and maybe you have to enter in manually.

Don't know if this might help but I'm on three network with generic UK firmware and in my network settings I have "4g (preferred)"
It's. 108 firmware and the customization number is 1279-4727. My 4g works fine.
If it was originally on the Virgin network it's possible I suppose that their firmware doesn't support 4G hence the option doesn't show - odd though. I can say for sure that 4G definitely works on the 3 network with the z1c though 3s 4G coverage is limited to the major cities at the moment - I've got a fairly ancient sim card from my old iphone 4 and that works fine so you shouldn't require a change of sim card. I would definitely try flashing the generic firmware and see if that solves it, doesn't need to be 157 - 108 is as good a bet as any and to me seemed better for battery life.
Sent from my D5503 using XDA Free mobile app
@spudata - thanks, that does indeed help. That's the exact firmware I downloaded (same customisation number) so its good to know it will work if I flash it.
@twilliams08 - given that I lost my root after the OTA update I'm probably better off on .108
So now its time to read up on how to flash a Sony Z-series
If flashing new firmware doesn't works maybe that could help with problem:

Try with this app https://play.google.com/store/apps/details?id=com.tapbase.LTEswitcher, I choose LTE only on that app because when I choose LTE preferred, it just connect to HSPA

Moto g5 no 3g and no 2g- no calls. Only 4g HELP!

hello, friends. Specially those who are worried about the so many problems with signal moto g5 users face. Im here asking for help. i have a moto g5 (cedric) i was working almost fine with oreo stock. i say almost because some times when i lost signal it didnt recover like any other phone woud, i had to reboot. now from almost a week ago i had lost signal and now i only have 4g. no 3G and no 2G, so no voice calls going out nor incoming ones. i ve done hard resets, flashing stock 7.0 and going back to stock 8.1 and nothing. on saw 3g for a little moment coming back to oreo. i also flashed carbon rom wich is android 9.0 to see if a custom rom helped but it didnt. i only have internet now and sms. and this is very frustrating. ive checked persist folder and everything is correct there. i have my imei right, this phone is like new but not being able to call is like not having a phone at all. also why i have to reboot to recover missing signal? is just a pain. this moto phones are really problematic when it comes to Signal management.
things to consider too: im currently on stock oreo, just rooted to be able to check if persist folder was correct and to backup efs folder. also my operator uses 900mhz band as 2g and 3g wich is an european frecuency not common in latin america. maybe that has something to do with problems im facing. the rom has cedric_latam_cust as the baseband. can anyone help me find one frome europe? im wondering if flashing one from there could help. the weird thing is that it was working before with that baseband.
so many people losing 4g, i could be glad if that was my case and had 2g and 3g only with full internet and calling capabilities.
im sorry i know it is a little bit too much information. but i really need the help

You could get your country firmware from here.
https://mirrors.lolinet.com/firmware/moto/cedric/official/
And don't flash older version firmwares as it will brick your device.and you should try a different sim card in your device to know if there is a problem in sim card or the device.

In my country we have 3 mobile operators. Movistar won't work (don't know why), the other works perfect on my phone. Mine from a week ago only work 4g. This afternoon it worked 3g but when I rebooted it stopped. Only 4g again. So no calls.
The first screenshot is with 3g and no signal
The other 2 is when rebooted having activated 4g

It seems the problem is API as you are getting 4g but no calls then it could probably API only, try editing the API or creating a new one. You can get the API configuration from the internet or the device which you get calls.

Did you try a different sim card in the device, does it working??? And does your service provider support LTE over call??? If it doesn't then change the preferred network type to LTE/CDMA/UMTS auto(prl). And switch your sim card to sim slot 2.

I haven't tried another from my company. But from other it does work well. Mine doesn't have lte over call. So when I try to call it switches to 3g and right there loses signal at all. I have to restart the phone to get 4g again

Problem 4G+ Galaxy note 10+ (SM-N975F)

Hello everyone, first of all I would like to apologize because I am French and I don't speak English very well, but I think you are my last hope for the trouble I am currently experiencing.
I own a Samsung Galaxy Note 10+ (SM-N975F) with a Rom Surcouche Operator Bouygues Telecom :
- N975FXXU4CTE9/N975FBOG4CTE9/N975FXXU4CTE9
I wanted to remove my Bouygues Telecom Rom Operator to install a Samsung Rom Stock without any overlayer operator. The operation is well finished so I am now on the Samsung Rom Stock:
- N975FXXS6DTI5/N975FOXM6DDTH7/N975FXXS6DTI5
Except that since this change of Rom I have almost no more 4G+ where I live knowing that before I was always in 4G+ So I would like to know why just by having changed the Rom I lost my 4G+. ( Worries which lasts since September 21st, 2020 ) I wanted to go back but I passed from a bootloader 4 to a bootloader 6
Knowing that I'm with the Free operator, I tested my Free SIM card in my wife's Samsung, I'm getting 4G+ so the problem is not my SIM card, I also sent my phone to Samsung, the phone has no hardware anomaly so it's from the change of Rom, I tried to reinstall the same problem, I also made the wipe I tried everything ...
I also have at home a 4G+ router with a 4G+ plan with the operator Free and I am in 4G+ at full speed ...
I hope to get some help from you because on the French forums I don't have a single answer ... Thanks in advance for your help and sorry again for my english
Test the internet speed on both phones using your sim's data plan with speedtest. If the speed is the same in both then the problem of the 4G indicator is only aesthetic.
Hello bigcalvin, unfortunately I have tested but the speed is not the same at all in 4G+ I go up to 235Mb/s while in H+ I go up to 3Mb/s so there is no problem with the 4G indicator

Have you tried in different areas? What it seems like, is that the stock Samsung ROM is not compatible with your carrier. With system on a chip (SoC), carriers can turn off bands that they don't need, or as a means of locking you into their network.

Honestly I'm not going to lie to you I've tried everything I've tried a Bouygues télécom rom (bog) a SFR rom (sfr) a France télécom rom (ftm) and a Samsung stock France rom (xef) with my old Bouygues télécom rom (bog) bootloader 4 I always get the 4G+ since I changed my rom and I switched to bootloader 6 I never get the 4G/4G+ again and I sometimes get the 4G+ logos but there are 10 seconds left and then switch to the H+. ..
Hello, sorry for the double post but I don't know where to find help you wouldn't have a solution to my problem? Thanks in advance
I don't understand anything anymore on this phone knowing that my wife and at free and I can receive the 4g very well. I have a 4g router, I can receive the 4g free and my phone since the update doesn't receive anything anymore, I have to go out of my house and walk a good 100 meters to hope to receive the 4g whereas I didn't have this problem before I made the really strange update...
No one would have a solution to give me or manipulation to do I take all the information.
Try a "reset network settings" if you haven't already.
Clear the system cache on the boot menu; it never hurts to do so.
Hi, thank you for your answer unfortunately I have already reset the network settings I have also done the factory settings system cache also reinstallation of a new rom I had to do it about twenty times but still nothing :/

Yeah pretty basic stuff... that's all I got
Most likely a settings issue but you probably know more than myself at this point to troubleshoot this problem.
Try doing Google searches and view the results for other Samsung phone models and years.
Most times I can find a solution like this or trip over it as an indirect result while searching.
Some of the Samsung software issues have been around for years...
I've already searched everything on google I'm French I've searched on English forums and everything but I can't find anything at all.
I am in France with the mobile operator "Free" which uses the frequencies 700mhz/1800mhz/2600mhz I would like to know if there is a possibility on this phone to choose the frequency that I want one by one I have the impression that it is my 700mhz frequency that has a problem on my phone :/
By using the free App 'Shortcut Master (Lite) from Google Play, you can get access to the Network Settings. In there you can make Band Selection, allowing you to test network connections and performance per band (=frequency) or combinations of bands.
See following thread: https://forum.xda-developers.com/ga...guide-hidden-network-settings-exynos-t3995501
Hope this helps!
Hello OnnoJ, unfortunately I have already tested with this application so it doesn't work. However I compared everything with my wife's phone a Samsung so I have exactly the same settings as on her phone ...
I have to go out of my house and walk a good 200 meters to hope to get 4G, however I specify that before I made this famous update I was always in 4G at home inside and outside of the house and this is not a concern of the mobile operator because otherwise my wife would have exactly the same problem as I have now and I would also have exactly the same problem on my 4G router ...
I think I've done everything and above all I've tested everything and unfortunately I had Samsung on the phone and they put the blame on the operator whereas as explained above my 4G router and my wife's phone have exactly the same mobile operator so they would have the same problem as me ... ...
I would try to revert to the newest firmware that your carrier uses, just to see if the issue is about the bands, search for the latest firm for your carrier, provided that it is of an equal or higher bootloader version to the one you currently have installed, that is what I would do
@thominekevin76000.
Not saying it may help you, but the application works fine for me to access network settings. I use it all the time, as it helps me at home and at work to make the optimum band selection for that specific location to prevent hopping between different cell towers and to have a stable and fastest possible 4G+ connection. CellMapper app allows me to see connection possibilities with the various cell towers and their power.
Hello winol, I can't go back to my old Rom because I had a bootloader of 4 and now I switched to a bootloader of 6 so I can't go back :/)
