Little problem after bootload unlock - Xperia Z1 Q&A, Help & Troubleshooting

Hey guys, i need a help with something that happened in my Z1 after i unlocked the bootloader.
Well, i did the unlock to install some ROMs, i installed all pretty good withouth any problems but something was wrong...
I installed whatsapp, and trying to access the whatsapp web i saw that my phone won't read the qrcode, the camera keeps focusing in a loop and the code changes...
I tried in another computer and the same thing happened, i tried also another phone in my PC and worked, well...
Looking for help through the internet i didn't found anything that works, so my last hope is here in XDA.
Someone can help?

I guess.......and next time when you wanna root etc. just have the patience and read everything that is written here.
Never the less some phones are more durable in that matter ( i don't know why ). Some phones are like butter, 1st attempt and you are rooted. And with another you sweat like a pig and even then you can't do it right :laugh:
well
Well,
I hope it'll get better
thanx
Before bringing your phone to service you could try:
- a factory reset. Maybe the unsuccessfull rooting attempt has messed up something you can fix this way.
- flashing a RUU and see if the issue remains. This usually sorts out...

stuck like chuck. HELP!

hi everybody,
I'm stuck!
I' tried everything I can think of, I've search hi and lo and I cant find a fix for my problem. My phone for the last several months has been working flawlessly with twrp/trickdroid but since there dosen't seem to be any more support for trick droid I decided to put another rom on the phone. Now I've never had an issue doing things this way but something is screwed up and I could use someone who is smarter than me help. I wiped the phone and now I cant get my phone and pc to communicate. Everytime I try to adb sideload i get an error stating device not found. twrp recovery is still on the phone and i can still boot into the boot loader if needed. I just cant put my new rom on the phone. I've done everything i can think of, searched everywhere i think possible. this isn't my first android that iv modded but it is the first time i haven't been able to find a solution for my problem. please help!

O2 UK D5803 Can't downgrade to kitkat, gets to wavy lines, freezes and then restarts

Hi all, i've got a strange problem with a D5803 which is bootloader locked and on the O2 network in the UK whereby I can downgrade to kitkat with the generic D5803_23.0.A.2.93_Generic GLOBAL.ftf or any other variation of it and when flashtool has installed it and I restart the phone it gets about 10 seconds into the wavy line bootscreen and then freezes and restartsthe phone. After it's done that it then gets back to the wavy lines and freezes again and has an annoying noise where the sound of the bootscreen's audio has glitched and then stays in a bootloop.
I've tried all different manner of ways and have exhausted all my search & google-fu and can't find out what's preventing it or a way to get around it, I only want to root it and nothing seems to work! The only ftf that always works are the ones that you can find in Experifirm under O2 pay monthly, they always install fine but none of the others will no matter which version I try, kitkat, 5.0.2, none! I've also tried to build my own firmware with experifirm but that also resulted in the same problem so i'm at a loss as to what to try next!
Has anybody got any ideas as to what might be wrong or help me to at least get root please? I'd really appreciate it, thanks in advance.
I found out what my problem was, can't say that i'd noticed it mentioned, only found it by looking at videos and pics taken of Flashtool which had ticks in the APPS_LOG & USERDATA boxes which then proceeded to resolve my issue and flash properly! All them hours and that's all I needed to do, now rooted on lollipop as I wanted!
great you found the solution bro!
:good:

Forgot screen lock, how to solve?

Hi all! I have a somewhat embarassing problem.
My son is using my ZUK Z2 Pro. He loves it, thinks it´s awsome and loves that noone else has it
So the other day, he decided to change his password for the screen lock. Problem is, now he doesn´t remember his new password.... he has tried at least 100 different ones and cannot remember it.
I´m trying to find a way how to solve this. Erasing the device via Google find my device doesn´t seem to work. There is an erase/wipe option, but nothing happens when I click it.
I think the phone was running on stock ROM and stock recovery (not sure but I think I tried different ROMs on it but decided to flash stock ROM before giving it to him). At least when I boot into recovery it looks like some stock recovery. I don´t have any option to wipe/reset device in there, just to flash (which fails).
Bootloader seems locked. I tried to issue a "fastboot -i 0x2b4c oem unlock-go" via fastboot, but it fails. USB debugging is probably not enabled, if that makes any difference.
Any ideas?? Feels so stupid not to be able to solve this, I mean it´s a perfectly good phone with one small issue that seems nearly impossible to get around. At least son leared a lesson

Unable to unlock bootloader due to errors within ADB and fastboot

Hello,
this is my first thread/post on this forum, if I did anything wrong please don't be super harsh and inform me to what to do better, thanks.
So why am I asking for help anyways you may ask, well I had my old Xperia Z1 laying around here for quite a while now and wondered if I could do anything productive with it.
So I came up with the idea to install a CFW like Lineage OS or something else.
This is not my first rooted and cfw phone but the first one what gives me nightmares and a headache.
So after reading all of the nice guides how to root it and how to unlock it, nothing of them is working for me, most of the threads have missing files which I cannot find on google or other just simply won't work for me.
First of all, I have rooted my phone via KingRoot in the meantime since the other methods where not working either.
I have turned on usb-debugging and also allowed installation from unknown sources.
And there we start with the first problem, downloaded the google SDK and installed all adb things I needed, did not work, then I tried it from the official sony website, downloaded the usb-driver folder and tried to install it manually, won't work either, because the device manager always gave me error code 10 "device cannot be started", I tried different sources and even die google studio thing and everything ended up with the same result.
Same error code even when I tried to activate fastboot on my phone by pressing down the volume up button, pluging the usb cable in, and yet again the same error message for this device too.
I am using windows 10 and never had such problems before with sony devices.
I hope someone of you can help me out to find a solution, if you need any further information, just let me know.
Did you solve this?
I have the same problem

This may sound stupid or ridiculous, but yes I managed to work it out and was able to install the CWF on my phone which is working perfectly fine.
Since nobody was willing to help me I just skipped the part where I wanted to post my solution but yeah, this may help you too.
So what did I do? Simply I stopped using Windows 10 for this project, I just used one of my older PC's which still had Windows 7 Ultimate on it.
I just rooted the phone via KingRoot, since it was the only solution what kinda worked out for me, then I was able to install all needed SDK, fastboot and ADB files on my PC and was able to use the ones from the Sony site itself this time and after plugin in the phone to the PC, it installed everything else what was needed for the device manager.
After that was done with no error I was finally able to unlock the phone via the command which you can find also on the Sony website.
If you find this helpful or need any extra information just let me know, maybe I can help you then. Oh and if you found out a solution for you what worked, would be nice to hear that too.
