[Q] No Signal in Lollipop D6502, any way to fix? - Xperia Z2 Q&A, Help & Troubleshooting

Hey, so I was impatient of waiting for Lollipop on D6502, so I went to XperiaBlog and saw some people asking if they can flash the D6503 FTF to D6502, they said it was okay but your phone is from now on D6503 and you won't have 4G, but everything else will work. So I flashed it, my phone worked perfectly, only that I can't get a signal on my phone. WiFi works fine but cellular network has no signal. I am aware that there is a zip to flash to fix the modem issues on D6502, but that requires recovery and I haven't rooted to gain recovery nor will I plan to. Is there any way without rooting to flash the D6502 modem zip? I just cant stand it because without cellular the whole name called "phone" is just diminished. Thanks =)

That does not really help. Surely there has to be a way.
I forgot to mention I DID download the baseband patch but the D6503 ROM had only .sin and .ta files, while the patch had multiple folders and files with .b00, .b01, etc.
Is there a way to put the patch in the baseband folder then flash the ROM again? Thanks =)

There is a way root, install recovery and flash the zip.
If you don't want to that you could try and unpack the ftf, open the ftf replace the files and repack the ftf. I have no idea if that possible though. Google it.

Install some custom kernel that has recovery (that won't allow you to boot lollipop), flash the fix (eventually also root your device) , flash the original lollipop kernel and you should be done.

Couldn't I just wait though for the D6502 ftf for Lollipop to come and flash it? Would that fix the baseband problem?

If you're already on lollipop you won't get any update soon, only if you downgrade back to kitkat.

No, what I meant was I flashed D6503's lollipop. D6502's will be out in a week. I downloaded the D6503 ftf from XperiFirm AND CAN download the D6502's ftf when it comes out soon. I was asking if it was fine to flash 02 over 03 and not get any more problems. Thanks =)

Yeah sure, that'd work. Just make sure it's a clean flash. (Everything deleted on internal sd)

Updating to Dogg Rom v4.3

I come from 4.2 pre-rooted deodexed rom. Can I just flash the zip file of Dogg Rom v4.3 from recovery or do I have to flash. 290 FTF first?
Thanks

I posted it here cause apparently after 3 years of being on XDA, I can't post in developer's section, because I never had anything to ask!

I have not tried from 4.2 stock, but no harm in trying. Just have the latest flashtool ready and a 290 .ftf. You do have an unlocked bootloader as well?
Yes, but I don't have a good Internet at the moment so I wanted to skip the download of FTF

@hamdogg ?
you may have to flash the boot.img from the .zip to get a working recovery? read post 3 of DogGrom!
If it all goes to pot you will want a ftf to flash to get a working phone again... and alwar use protection - if have a backup

Hi all...
umm yes it should work. I've not tried flashing ontop of 4.2.2.... but its a sony base, and the most important files will be replaced when you flash the new ROM...
But like blue said... if it doesn't work then you'll need to
1- flash the .290 FTF
2- then recovery, and then
3 -doggROM..

In one of your other posts you mention relocking the BL? It has to be unlocked.
Also if you are on a 6802 you have to be coming off a c6833 firmware for some reason, this is the most likely I think

flash the latest FTF for the 6833 (use flashtool and put the phone into flashmode)
then flash the boot.img in the CM zip (use flashtool and put the phone into fastboot)
then flash the CM zip (from recovery installed in step 2)

[Q] Which file should I flash first?

Just downloaded 4.4.2 for XZU C6802, it has 2 files:
C6802 4.4 IN 757 odex ROMflash01.zip (1.02GB)
C6802_14.3.A.0.757_Generic IN kernelonly.ftf (11.3MB)
Questions:
1. Is this a official release? why not in ftf?
2. Why there is a extra kernel there?
3. Do I need to flash both of them? which should flash first?
4. Will it automatically in rooted state after flash?
5. Any other things need to notice?
Current State:
C6802_14.2.A.1.136, Rooted, Unlocked, CMW and TWRP both installed.
THANKS!
You've apparently downloaded a CMW file of the latest update. Why is there a stock kernel in the package? I don't know, but it doesn't hurt to have it. Just flash the ROM, and not the kernel. I assume the ROM has a kernel with CMW/TWRP, but we can't be sure until you try.
Is this the DL that came off a .cn forum?

2.If want to keep recovery and root, flash FIX_Z1(ZU)-lockeddualrecovery2.7.115-BETA.flashable.zip (http://pan.baidu.com/s/1kTDiMiz).
3. switch off, enter flashing mode.
4. flash that ftf kernel.
5. Reboot, already in 757

[q] very big problem on my xperia z ultra!!!

I need your help guys!
Just yesterday, i was looking for a custom rom for my xperia z ultra. The reason why i want to install custom rom was to get rid of the NFC and BLUETOOTH problem that i was encountering. So i have successfully installed a rom from here (http://forum.xda-developers.com/showthread.php?t=2800414). but it was like a disaster. THERE IS NO MESSAGING APP so basically i cannot send or receive messages, the NFC is still not working and still my bluetooth cannot detect anything, and the Model number of my device changed from c6833 to c6806. I dont know where to start now. All i want now is to go back to its original state. I am willing to pay/donate to someone who can help me bring this device back to its original rom/build/model/etc.Thanks in advance.[/INDENT][/INDENT]

you flash the .ftf with flashtool.
That's right, enable usb debugging in developer settings and then use flashtool to install the ftf. There's a link to a tutorial in the link that I posted earlier and a downloadlink for flashtool and the ftf file too.
Yes for messaging app you will need to download Hangouts app from playstore. Its strange because I use the same ROM on my C6833 and everything works as it should. Perhaps you have a hardware problem.

Help rooting Z2 tablet

Hey guys!
Ive been trying to figure out how to go about rooting my tablet but since I am new at this stuff I just want to make sure I dont **** up
My questions are:
1. My tablet is 5.0.2 atm, as far as I know I have to downgrade to be able to root?
2. If I need to downgrade I believe I need a FTF file, I have a LTE version which is bought in sweden. Do I need a specifik FTF file for my country or can I use http://forum.xda-developers.com/showthread.php?t=2741233to downgrade my tablet?
3. Can i still use this guide http://forum.xda-developers.com/showthread.php?t=2792056 to root my device after I downgraded the firmware or is it outdated? If its outdated is there any updated guide I can use?
Any help is appreciated!

1. There is this: http://forum.xda-developers.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461. But it ain´t give proper root and there is also some security concerns with it but your decision.
2. Yes. You need FTF file which is 4.4.2 firmware for you device. Latest rootable is 17.1.2.A.0.314. Here is download link for SGP 521 if you want. https://mega.co.nz/#!cN5ykLrL!0w38j4lWIHFm1rZdwexScG9Cpz2BghrSZPpLRkyTcL8 . However your link should work also. If you only use it for rooting it don´t have to be for your region.
3. Your link would work for rooting properly. However there is other methods too.
4. After you achieved root just install custom recovery for you device and flash latest prerooted firmware for your device with it and you are good.

There is no need to unlock bootloader if you just want to root your device. Bootloader unlocking is needed if you want to try custom kernels or roms that use custom kernels. And yes this work for your device also.

Yes you can downgrade to 4.4.2 firmware with locked bootloader. After that you don´t need kingroot to root your device because @[NUT]´s dualrecovery pc installer can root your device before it install custom recovery. After that you can flash prerooted firmware (= .zip file) with custom recovery. Usually prerooted stock roms has whole firmware including kernel. Their also include SuperSu and custom recovery. And there is no need to unlock your bootloader in any step for this unless you want to do that.
OK so I flashed a ftf file from this thread http://forum.xda-developers.com/showthread.php?t=3061431 I don't think its right as its for HK etc. A 4.4.2 ftf. 17.1.a.2.402 HK/sa/as/kw.
I was on 23.1.A.1.28 in the UK as O2 UK being the 4g network. But according to that thread the 23.1.a.1.28 I was on is generic HK so I'm confused. How can I get back to my original then? Thanks

OK thanks I did it without the ta partition like suggested but wasn't sure if it was 100% correct. Should all be fine though. I'm currently now rooted and all fine but what I want to do is have a Pre rooted flashable zip of my ftf I've made so it is my actual stock ROM I'm running. I've looked into the prfcreator but don't wanna do it and run the risk of bricking my z2 tab. Have you used prfcreator? I guess all I need is my ftf file to use. The most update supersu zip I want. And then I need to somehow have the xzdualrecovery.zip but not sure if that's all I need or if I need the current Sony signed kernel or what. Thanks
