[Xperia Z1 Q&A, Help & Troubleshooting] Ratha ITC:
You said it booted up and sounded? So you see the booting screen? If so, it's preparing for your new Lollipop. You have to wait from 10 to 15 min.

Edit: But your problem is really strange because your phone can't boot even flashed with the untouched ftf lollipop... by the way, which untouched ftf did you use? where did you download from? or you made yourself?
[Xperia Z1 Q&A, Help & Troubleshooting] ljmanayon:
I assume it booted up because it vibrates and I can hear the sound. However, I can't see the booting screen (No Sony, Xperia Logo), nothing it's just black screen. I got the ftf from xperiafirmware.com. Yes, this is really strange, I can't seem to find any solutions, I don't want to give up on my Z1, not now. Thanks for taking your time in replying my questions by the way.

I just went back to 4.4.4 -- guess I'll be stuck here..
[Xperia Z1 Q&A, Help & Troubleshooting] Ratha ITC:
I don't trust other ftf made by anybody... I trust only the ftf that's made by myself. :o

Do you know how to create the ftf file by using flashtool? I recommend making your own one.

[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] masterofenergy:
Need to know if the problem is with the phone or provider.

My husband went back to Sprint due to lack of coverage & these service issues.

We still have the same problems. Almost every time he calls me, regardless of where he is, the call does not go through. It rings a few times and then just drops or goes to voicemail, never ringing on my end or showing a missed call. On the 2nd or 3rd try it goes through and I get his call. Now this also happens when I call him. There are also many times when we connect but one of us cannot hear the other.

I am mainly at home, while he travels the U.S. as a truck driver. Tmobile did provide me with some type of signal booster for the house, but it doesn't seem to have really done anything to help with these issues.

We now are paying for 2 plans and for 3 Note 4 phones through Tmobile. This is hurting us both emotionally & financially. My husband hates to call me and our 10 calls a day has become much less & when we talk he is already upset having had to call me 2 or 3 times to get through.

At this point he wants me to join him on Sprint, but we are already paying more than when we left Sprint & we are by no means rich.... The worse thing is We are paying for 3 Note 4 phones that cannot be used with Sprint. I had to downgrade him to a Note 3. Worse I sold our Sprint Note phones when we moved to Tmobile. This is just such a nightmare.

I have to find a way to fix the issue or I will have to go buy another phone & go to Sprint & continue paying for Tmobile until all 3 phones are paid for :(
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] vijovame:
I had similar problems, you can try to turn off VoLTE, voice over LTE. What number has your signal transmit booster? How many bars has the receiver booster? How many bars you have without the booster?

Edit: Welcome to XDA!
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] p8ntballa9362:
wow that sucks... ive experienced similar issues. im pretty sure its a service problem. i cant imagine 3 different phones have the same problem but then again im in that exact situation. ( all 3 note 4s have the same issue). try putting you sim in an old phone and see if it clears up. try to isolate the problem to either the phone or service.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] BACARDILIMON:
Well first it might be ur phone. If ur signal is not strong at home tell Tmobile and u will get a booster for your house. Also have them refresh u on network. On his end if he a truck driver T-Mobile nor any carrier covers all of the USA. You gonna have dead spots while driving thru ghost towns. If he is in major city then he should be good. No phone works every place. I have had them all and while traveling Verizon was the best but my ass bleed paying 400-700 a month for my phones as data was a killer. Now I don't travel as much and Tmobile has been great.

[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] masterofenergy:
Thanks for replys... it was a defective phone!

I cannot believe after over 6 months with the same problem no one at T Mobile ever suggested it was the phone. in the very beginning they did replace the SIM cards our phones but it did not fix the problem. after giving it a lot of thought I realize that my phone was the common denominator in the problem. I put my sim card in our backup note 4 phone that my husband is obviously no longer using since he went to sprint. All weekend my service was fine. my husband was able to call me and get through and I was able to call him and get through every time. T Mobile is going to send me a replacement. Very happy that it wasn't the service and that I'm not going to have to switch to sprint which would have been a severe financial hardship for us. thank you to those who replied trying to help me with this issue. Much appreciated :)

I had the exact same problem, just double check the model number of your phone.

I installed the files from the guide on my D6503 which gave me no network but everything else worked perfectly.

If this is the case you should be able to find a flashable one for your device and just flash it over what you have now as per the steps in the guide, this was all I did.

I'm trying to give my Z2 (D6503 / 23.1.A.0.726 ) root access (never had it before, haven't installed any CFW either before).

However I'm already getting stuck at getting into the recovery mode to flash the flashable.zip file.

Might this be because my phone has a locked bootloader?

Or do I actually have to skip this part and only do the backup of my files through Backup & Recovery?

I have tried doing it several ways, when I use the Volume Up button the light ends up blue and shows black screen.

When I do it with the Volume Down button it ends up green for a short time and ends up totally black.

I've tried using the ADB Reboot method (adb/fastboot) too, yet it doesn't give me the Recovery screen.

I've looked at several other posts but they're leading me to flash DoomKernel, but those posts are from a year ago, so I'm not sure.

(.28 update doesn't show up for me yet in the Software Update somehow)

Anyway, thanks. o/

EDIT: Backed my files up through Backup and Recovery. Since I figured out that TWRP was only available for those who rooted it once already.

Went through the whole process and got my phone rooted (to .28 from the newer thread), great tutorial. :)
