no connection to carrier after encrypting LineageOS - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

Hi,
I am not used to flashing or other things regarding smartphones. So I flashed current LineageOS on my Xperia Z3+ and it worked well. But after encrypting it, the network is not found and the SIM cannot be unlocked (it asks for PIN though). What might be the cause and what could I do to unlock the phone or to repair the modem, because I think its something with the modem. Help is much appreciated.

Wi-fi problem on UNLOCKED CLIQ

Dear Modders I know this is only HTC braned phones forum but please don't delete my post because this is not brand problem but common unlocking maybe somebody can help me here ...
After long time tests I came to on result.
My phones wi-fi not working becuse it's unlocked ant then I insert another sim card which is not working in my country and there is not GSM antena indicator on that time wi-fi starts working but then I put my normal sim card which is working in my country and phone getting signal from GSM network it blocks wi-fi and I can't use my wi-fi even after that when I insert back the other cart which don't have network coverege in my country again it's not working till I fully format phone from settings.
Please if someone can have solution with this post here or tell me how to fix this so have working phone wit wi-fi and gsm network togheter
is your phone rooted?
Rooted or not, try a Factory Reset. That might fix your problem. If its rooted, flash the rom again after doing a full wipe.
Dear nephron phone is rooted I tryed reflash rom many times and no success even after full wipe. I think my problem is that my phone unlocked with the code I get from T-mobile and when my phone uses GSM sim card and I am getting registred in gsm network wi-fi can't find any network but when I put other sim card which can't register in my country because of there is no network for that sim card that time wi-fi works perfect.
So by my understanding GSM signal is not letting wi-fi to work how to do that to get working togheter ?? and also I have some doubt about unlock code can t-mobile have to unlock codes for on IMEI one will unlock carreir and another will unlock all functions? or I am wrong?
Please is there any expert on this issue so can help me with this...
Here is the my boot.img file maybe this will help to fix my wi-fi problem. please some adnroid developers maybe can give a hint or help me to fix my problem..

Support Request - Network Issues

Hello,
I recently purchased an i9305T 2nd hand but I am continually getting network errors with my Vaya (Optus) Sim.
I have not been able to get mobile data to work at all, using various configurations.
I have tried flashing a custom rom (CM Nightlies) and flashed various modem packages but still the same problem. I can send & receive texts and calls for a few mins, but then it comes up with network unavailable and nothing will work.
I'm not sure if the phone is locked, and at one point I figured it was locked so I purchased an unlock code but I can't use it as I am unable to use ANY USSD codes (I have tried heaps) except for the one to check my IMEI (Which is fine).
PLEASE HELP ME!!
Thanks,
try flashing THIS
is a Modem/Radio for your contry(Australia)...if this doesn't work try flashing the firmware for your contry(get it from samfirmware.com)...
if even this doesn't solve your problem it means it's a hardware problem...not software..

[Q] Unlocking + Signal Issues post Flash and IMEI fix

Hi All,
I've trawled through this forum for quite a while and haven't yet found any answers or similar cases to the issue I'm currently having. Here's a summary of where I am at the moment with my i9305 LTE:
- Got a i9305 locked to EE.
- When EE quoted £20+ and 10-20 days for unlock I started looking at altenatives.
- For one of the alternatives, I flashed to get root and I believe I lost my IMEI. I didn't have an efs backup and was unable to restore via stock flashing.
- Luckily, I had a screenshot of my settings so I re-wrote my IMEI using QPST.
- Decided to go for the legit unlock this time so called EE and paid for the unlock code.
- Pre-root, when I put in my unsupported SIM I would get a prompt for an unlock code, but that doesn't have anymore. While waiting for the EE code, I found that when I inserted the unsupported SIM, I would sometimes be able to connect in very specific locations (e.g. certain places outside the house). Wi-Fi works perfectly.
- When the unlock code came, I attempted to enter it by getting to the prompt using "#7465625*638*#". Although, when I enter the code here, it does not accept it (I have an unlock and an unfreeze code, neither work).
- I have trialed the SIM in various other phones and have had no problems with signal at all, the problems arise when I place the SIM in the i9305.
- I have tried changing the modem, so far no luck...
No idea how to go about fixing this... At the moment I can't use it as a phone.
Here is some more info:
Samsung GT-I9305
Nameless Rom 5.0.2
Baseband: I9305XXBLL3
Android Version: 5.0.2
- Should I keep trying different Modems?
- I've tried to verify whether phone is locked or unlocked, but *#7465625# doesn't work, do you know any other ways that I can diagnose sim lock status?
- Will different ROMs or kernels help?
Thanks for any help!
-- UPDATE --
Have flashed back to stock 4.1.1.
I attempted to sim unlock via the *#197328640# approach, but wasn't able to get it to work...
My current next hope is to try and restore my i9305 to the point where it asks for a code to unlock upon entering a new SIM again... Would really appreciate any help, Thanks!
I've still not been able to fix, but will update when I do in case it helps anyone else :good:

Xperia T simlock after flashing?

Hi All,
I recently used Flashtool to flash an Xperia T phone, with the Android 4.3 software (LT30p_9.2.A.1.199_Generic UK.ftf). I used the default settings, and the flashing itself was OK.
However, after switching the phone on, I realized that the sim was locked and I got the usual screen with the request for the authentication code etc.
Is it possible that the flashing destroyed phone simlock settings?
I tried to flash another Android version as well, with the same result.
Unfortunately, I haven't made any backups before the procedure (shame on me!).
Is it possible to unblock the simcard now (given the fact, that it used to work fine before)?

Samsung SM-925A Updates and/or Custom ROM

I received a free Samsung S6 Edge from some friends. The phone had a busted battery which I fixed. The phone is still on the original 5.1.1 that the phone was released with.
When I try to do updates it says DM initialization not ready. Check network or SIM card. When I received the phone I was told it doesn't work with cell service. I checked to make sure and it definitely doesn't. There are no options for cell service in settings or the drop-down menu. This phone is missing IMEI numbers, IMEISV numbers, and baseband versions too. The only way I found out the IMEI number was it was printed on the back of the phone.
I am fairly certain the problems are software-based and not the motherboard but I don't know enough about phones to be sure. Do you guys know? I also want to remove AT&T from the phone to install a custom ROM on the device. (There is no OEM unlock in the developer options) Can I flash SM-925F firmware on the device to make it factory unlocked or will this brick the device? Will flashing the original SM-925A firmware fix the problems with the device? Please let me know if you need any more information to answer my question.
I found this: //G925A\\ Nougat 7.0.1 Latest Stock ATT Odin files G925AUCS7ERC1 | XDA Developers Forums (xda-developers.com) Should I flash this on my device? Will it fix any of the problems I had on it?
Can I flash the SM-925F firmware? Is the hardware of the factory unlocked phone and AT&T versions the same or will it brick this phone if I flash it?
Since the phone is AT&T you'll have to go through AT&T for the unlock codes before you can flash anything other than an AT&T ROM. To my knowledge there are no custom ROMS for the S6 Edge, but I could be mistaken.

I know this phone is old news however, I actually have the S6 and S7 edge lying around and so i got bored lol...here is my dilemma; Evidently the phone (S6 Edge G925A) had an abnormal factory reset, which is a load of BS, and now I can not get that security detail, which you know calling Samsung always ends to NO AVAIL!! I have flashed with Odin the firmware that my device is on the ERC1 firmware and still I get stuck @abnormal reset. I've searched numerous sites, different forums and still to no avail. Something told me inside that you was the man to drop a line to, any leads or info will be more than appreciated brother...Thanks for your time....
PSSS....
I got my unlock code from AT&T some time ago but the code is 16 digits long and code only takes 8 digits, and of course to hear AT&T tell it, " I simply must not putting the code in correctly"...lmao
