Xperia Z1 stuck in bootloop! please help! :( - Xperia Z1 Q&A, Help & Troubleshooting

Hi people of XDA, this is my first post on the forums. A few hours ago i rooted my C6903 using Kingroot and all went well (as far as i know.) I then installed remove kingroot and install SU file.i mainly rooted the phone to use Freedom,GameCIH, Game Killer, Game Guardian to try and get coins on a game called SongPop. However, as i was using freedom to buy coins ingame, the app crashed (and so did GP Store/GP Services.), I realised those apps havent been updated in years and i decided to give up. So i said what the heck and uninstalled root through kingroot. (again, all went well afaik). I then tried to open the GP Store. but it gives me some error that i cannot remember "white screen with try again later" so i thought restarting my phone would fix it. Anyways i hit restart and THE PHONE DOESNT BOOT ANYMORE. it shows sony logo then black screen then sony logo and so on. I am NOT an expert and i would very much appreciate a fix that doesn't include flashing a firmware as i've never tried it and cannot afford a new phone. also i live in a 3rd world country and my internet speed is very slow (~40kbps). please explain to me as you would to a noob
XDA, you are my last hope

Once Again Thank you SO much for replying . can you please confirm that this guide (cant post links) is legit? also. some people have said that i need to flash the older KitKat first. Is this true? Or can i just do what the guide says and flash the 5.1.1? (I was on 5.1.1 before bricking my phone).
1. how to install the newest generic Android 5.1.1 for Sony XPERIA Z1 C6903
a) first of all, check your firmware version (if you already have the newest one, you do not need this tutorial)
b) download and install latest Flashtool from this article
c) download also latest Android 5.1.1 (mirrors Google Drive or Mega) for Sony XPERIA Z1
d) paste the ftf file downloaded in step c) to folder „Firmware“ included in the XPERIA Flashtool
e) open the XPERIA Flashtool, click on flash and choose downloaded firmware, than click ok. Important - if you do not want to delete any data of your phone, just uncheck flashing userdata.sin file. All data will remain in your phone, but sometimes it can cause additional troubles. So it is better (and I recommend that) to do the backup of your personal data, than proceed with clean instalation and then restore your personal data.
f) turn off your phone and when Flashtool shows pop up window, connect phone to PC with holding volume down button
g) after few minutes all is done and your phone gets the new firmware

Dont worry....its good that you shared. But it is not a [rom] upload, that sort of suggests its a custom rom. This is just [stock firmware] and that the way i described it in the all in one thread.

Which needs unlocked bootloader, correct?
Which additional drivers need to be installed?
Is there a way to downgrade with locked bootloader? I am actually ok with the function of .199 but not with it's tons of bloat, and no way to install certain apps. No root is almost like having no sex ever.

Of course yes, flashtool is both for locked and unlocked bootloaders! The drivers I always install is something called "Gordon Gate driver", the FlashTool itself and this is enough for the phone to be recognized while plugging. Be sure to plug in the phone one time in flash mode before the final flashing so that the PC recognizes it and installs drivers, after that unplug it for a while and turn it off again because it will probably turn on, it always happens in my case when I plug the phone for the first time after f.e. installing a brand new OS and not every drivers are installed. Then run FlashTool and you can start the magic!
But, you can always disable certain apps in Settings>Apps>All. You will be actually freezing them (just like with titanium backup) but it's pretty useful. Aaaaand there are two ways of flashing recovery on locked bootloaders so that you can i.e. flash SuperSU .zip file with the app and appropriate binaries (you can find it on its dedicated thread here on XDA), that's what I'm always doing.
My phone is T. Xperia T.

Ok, I have still a notebook somewhere in the corner running XP. I'll see what this one can do. If I can downgrade to 4.12, then I can rrooooot that one. At least I would not feel so naked and vulnerable anymore.
Can Flashtool make a mirror or image of the current ROM?
And thanks bunches for your helpful answer!
Here are the rough steps to downgrade:
- use a PC which runs Windump XP or 7
- install Flashtool
- install drivers (in the Flashtool drivers folder)
- download a 4.12 FTF of your choice. Nordic and Singapore seem pretty good.
- switch phone to USB debugging
- open Flashtool, click on the flash symbol and chose flashmode, follow the instructions, don't disable any of the flashing options
- after successful installation root with DooMLoRD_Easy-Rooting-Toolkit_v17_perf-event-exploit
- after successful rooting update SuperSu
- install recovery CWM4XperiaT_v8i_JB
From here you can install a rooted 4.3 if you can live with it's shortcomings, or any 4.2. I choose Pure-X-Blaster 4.2.2.

[Q] A noob in need of help..

Hello everyone,
I am new here and I'm having really hard time going around the forums and searching for what I seek and everything is so confusing and I really need someone's help. I've never done this and it terrifies me to screw up my phone. Here's the deal, I want to root my Sony Xperia Z so I can remove the useless built in apps and maybe get a cool theme. I've been looking for threads but there are so many and I don't know which one to take, most talk about some firmware I don't even know what that is but I looked a bit on the internet and found out which is so here are my phone specs:
Sony Xperia Z
C6603
4.3 Jelly Bean
Bootloader unlock allowed: Yes
Firmware thing: 10.4.B.0.569
Any help would be appreciated, thank you so much.

Welcome to xda where everyone starts off as a noob
Don't worry we all make mistakes hopefully a moderator will move it in the right place.
Now to answer your questions
a) A firmware is the software installed on your device you have got it right in your specs.
b) The method of rooting depends on the firmware. The firmware you have does not allow easy rooting.
You have two options since your bootloader can be unlocked
1) Backup your ta partition using the backup utility and store it on your computer. Unlock your bootloader and root your device by following the guide posted by cookie ninja in the xperia z
android development section
http://forum.xda-developers.com/showthread.php?t=2656698
[GUIDE][ROOT] How to Root 101 Firmware and regain LB
2) Downgrade your firmware to android 4.2.2 by flashing an FTF file using flashtool (you can find these in the development section as well) and then root using doomlords rooting toolkit. You can then upgrade to even android 4.4 by flashing any of the pre rooted roms from the development section.
All the best.

Hi
Welcome to xda
First you cant root 4.3 only if unlock bootloader and the unlock not hard but better try downgrade to 4.2.2:
Download a software called flashtool from here and install it then after install finish go to the place where you install flashtool and find folder called DRIVERS open it and you will find an exe file open it and select xperia z- flashmode drivers - fastboot drivers then install
Get an FTF file for flashtool like that
After the ftf download finish put the ftf file in "frimware" folder in the place you installed flashtool
Open flashtool then click the lighning icon
Select your downloaded FTF
After few minutes you will see screen appear says WAITING FOR FLASH MODE
Turn off you phone
Hold the volume down button then connect your phone with your pc with usb cable
After few minutes you will see your phone downgradedto 4.2.2
THIS WILL DELETE ALL YOU APPS AND DATA IN YOUR PHONE!!! So better make backup!!.the phone must charged to 80%
Now root your device with kingo root this tool not working on 4.3 that why i said must DOWNGRADE
Install CWM and TWRP recovery here
After finish get a PREROOTED ROM like this
Flash it in recovery
Now we finished
Other notes: the flashtool and FTF can repair your phone if bricked so dont panic if that happened just use the lighting icon:angel:
Hit thanks if helped

Sony smartphones are nearly impossible to hard brick, unless you restored a wrong bootloader TA partition.(the one not from your own device)
The worst case scenario which you can get is total wipeout of every data you have on your phone, so always make a backup of things you need before doing anything.
The things you will need:
1.Basic computer skills
2.Knowing the bootloader of your phone
3.Knowing how to use custom recovery (cwm or twrp)
4.Knowing how to use flashtool
5.Keep a backup of firmware files (ftf) in case anything happen
6.Always check the forum in case the old backup of something of yours won't work in your phone after you updated
Thank you guys, you're all wonderful.

If you want stock unmodded one you can do it without root. And if you want a rooted with dual recovery you will need root
But I advise you not to use stock kitkat because its lags alot and low battery life
Try those if you want:
Stock no root needed ( flash via flashtool)
Modded and fast with Root and recoveryROOT NEEDED

I made the mistake of unlocking my bootloader without making a backup of my TA, so make sure you don't make the same mistake. Not an issue really unless you REALLY want OTA updates.

Sounds great so far, one more question, is that sonny flashing tool (EMMA) is suitable for flashing STOCK roms? Or i need something else?
We often use flashtool made by guys on XDA so I would advise to you to use the same.

Emma only works with an unlocked bootloader. Use flashtool from flashtool.net instead

Flashtool issue

Hi guys, sorry if my english is bad.
So, got this problem: after using lineage for a while, I wanted to get back to my xperia z stock firmware, using flashtool. The only thing wrong in doing it, it's "error root: this bundle is not valid". When flashing in complete, I turn on my phone, I got the sony background, and then nothing, just the background brightness on. What can I do? I already used several versions of flashtool, and several ftf firmwares.

U can ignore that "error root: this bundle is not valid" !! It has no meaning for flashing .ftf firmware !!
But it was really important for me to use flshtool 9.18.6 (with 3 drivers; (fastboot), flash, lagan and z). And the only firmware, that works for me was Jelly Bean (4.2.2). Nothing else has helped. Before that I had the same results like u: the background brightness on after flash.
Hope it helps.

As far as I know is OTA update with unlocked bootloader not possible. So you can use Sony Flash Tool "Emma" to update with unlocked bootloader or the Flashtool from Androxyde. Alternative: lock your bootloader with Flashtool and use PC Compagnion from Sony and unlock it again after the flash, if you want. This is what I had done - so I recieved lollipop 5.1.1. (Maybe it is good to write down your unlock code and IMEI - but I think Androxyde flashtool stores it; check it!)
If you have backed up TA.img before hand, try flashing that, if backup of TA was done before BLU then you can flash TA.img and fix your phone with PC Companion in dead USB device mode
