Boot loop and can't enter recovery - Xperia Z1 Q&A, Help & Troubleshooting

Hi, I am having an issue where my phone is boot looping and I cannot enter recovery using power + volume down
My phone is the C6906 from Rogers and locked bootloader
I was on RockZ1LP using the DualRecovery rooted and working fine, I decided I wanted to go back to stock to hand the phone off to my gf since I have been using my note edge for a while now.
I downloaded the stock FTF and flashed it via flash tool. After that I haven't been able to boot successfully and have tried many different firmware versions with no luck.
I'm convinced if I can simply do a factory wipe it should work but I cannot get into the factory recovery. Anyone have experience with this?
Any help will be appreciated, thanks

did you tick wipe APPS_LOG and USERDATA on flashtool ? you also can use pc companion to refresh your firmware

Your phone was rooted and custom recovery installed, why didn't you flash a pre rooted zip with custom recovery. That would have done the job.

What's bad about root? As long as your girlfriend doesn't use a app that needs root privileges all should be fine.
Anyway good to hear you achieved what you wanted.

Some phones root can mess with OTA updates and whatnot, even snapchat looking towards blocking root users so I just wanted pure stock since we are long distance and I can't be there to take her through step by step every time work needs to be done.

no more CWM: [Locked Bootloader]CWM recovery 6.0.2.8 for locked bootloaders released

Hi everybody.
I have a problem
I followed the instructions from this thread http://forum.xda-developers.com/showthread.php?t=2187363&page=32 to get CWM for locked Bootloaders.
Everything was fine, it worked, I did already a backup with the CWM. Then I rebooted to the OS, went home, wanted to reboot to recovery to try to flash a custom stock based ROM, but now I can not get anymore into the recovery. Neither with booting up and pressing the volume key, nor with titanium backup and boot to recovery option.
I tried to reinstall CWM using the script, but no success to get into CWM. See also the screenshot attached from krabappel2548's script.
Any Ideas??

I don't know if that is the solution. I suppose files are gone or missing or anything like that? I wrote to the dev a PM to read this thread. I hope he can help us.
Just tested: Same issue with TWRP recovery....
I have a locked Bootloader (unlocking is not allowed), an rooted with the easy rooting script. Sony Xperia Z
I read from a user that it also has something to do with a file conflicting with the rooting for locked bootloaders, my XZ is in for repair now, but I'll take a look as soon as I have it back

I reseted the Z via sony update service (also did a FW upgrade), rooted with latest easy root and installed then CWM for locked bootloaders.
Now it seems working fine. was able to boot into recovery several times.

You can not root stock 4.3 with a locked BL that rom is for a rooted xperia. To do it you must flash back to 4.2 and root again install recovery and install a custom 4.3 rom not stock.

dual recovery is the "recovery" for your device. you can wipe data, cache,dalvik and etc on in. and using it, you can make nandroid backups, flash mods, and other fun stuff. To access it, turn you phone off. Then turn it back on, be ready because it should flash a GREEN led light suddenly, once it lights up click either up or down volume until the color changes. Down volume = TWRP, Up volume = Philz touch I THINK. not sure with the up volume. i use TWRP for backups and mods and roms.
Thanks

Root Z1. KitKat 4.4.X
Hello everybody!
I am a new member here and i would like to share how i root my Xperia Z1 (C6903) KitKat 4.4.4. Version 14.4.A.0.108 with
stock Firmware and locked bootloader.
So, i have tried to root my phone with different flashtools, installed drivers etc etc but no luck. Finally i came over this page;
http://forum.xda-developers.com/xperia-z1/development/newroot-z1-t2807092
First: I disabled any antivirus, malwareprogram it can give a false viruswarning and remove the file. I extracted the program Newroot to my desktop (How to find the program see above link).
On the phone: I went to settings/about the phone, scrolled down to the bottom to: Version, tapped version several times (for me 7 times) and a popup comes up and say you are now a developer. Now i set the developer options to ON and enabled USB-debugging. As default i also have enabled installation from unknown resources and unchecked the box Verifying apps. (Settings/SecurityUnknown resources/Verifying apps).
Now, I connected my phone to the PC with the USB-cable. Started the program Newroot from desktop, in the popup of the program i see that option "Check this to root your phone" is set by default. Now i just hit proced button and the rooting started, kept an eye on my phone and the phone rebooted. That was all and i had rooted phone with the superuser app in the apps section! :victory:. For some users first root does not work properly. If not sure you have completely root, check root with: Check Root. You can find it on Google store here:
https://play.google.com/store/apps/details?id=com.avaranasoftware.checkroot
If there is any error-messages, or if it says that busybox is not installed, use the Newroot program again to Unroot the phone instead. After unroot use Newroot program again to Root your phone. After reboot check again with Check Root, now everything should be fine. and both superuser app and busybox should be installed.
Good luck!
Note: Above is only a description of how i successfully rooted my phone. So i don´t take any responsibility for any eventual problems for others who root their phone.
Huge thanks to munjeni for this awesome program! :highfive:

So if i unroot the phone first, and then access recovery mode and choose that option, will it be the same as factory reset and i can use warranty of the phone if needed?

If you unroot the phone you will lose recovery.
If you want to unroot the easiest way is just to flash a stock FTF using flashtool.
And rooting does not void the warranty, only unlocking the bootloader does that

Now a couple of days i used the Newroot tool. I have installed some utilities with functions that requires root. Root Manager app says i have the Clockworkmod and most functions in that program does not work, and Titanium backup pro complains that my CVM- Superuser program can cause some functions to work improperly, and i should update my binaries to SuperSU for the program to work properly.
I installed SuperSU and in recoverymode i got the question if i wanted to "install the untrusted SuperSU Zip and this can not be undone". I chose no because i was not sure what could happen so i reboot the phone and after that i was not rooted anymore, i checked with root checker and my programs that requires root did not function. So i rooted the phone again with Newroot and i got root again and all problems were gone, root access was granted to all programs that required root, except for root manager...
So i googled about Clockworkmod and that mod is rarely used for the Z1-model, most used for Samsung and HTC.
So i wonder if i backup all my data via PC-Companion, can i choose "repair the phone" and it will turn back the phone to it´s original state?
Or do i have to flash the phone myself with a stock rom? I have search for my stock rom everywhere and i cannot find it. But with PC-Companion is it possible to return the phone to it´s original state?

Successfully returned it to factory state. Pressed *#*#7378423#*#* and checked, and everything is exactly as it was when i was rooted, so i assume the Newroot prog did nothing to my phone except for rooting it and installed recovery?
Anyway, maybe i will root my phone again now when i know it is possible to turn it back to stock to get the benefits from root.
Huge thanks gregbradley you made my day! :good: :victory:
No worries.
Yes the newroot process only roots the phone, it does nothing to the bootloader

update software atrix hd

i recieved several times a message saying that i have to install a security update (at&t), after some time i decided to install it but when i try to i get a status 7, another thing what do i need to install a custom rom on my arix hd, it has android 4.1 from at&t, unlocked bootloader, cwm, and carrier unlocked (i dont want to loose this), in my touchpad i just have to download the rom + gapss and install them from a custom recover, so i dont know if this is the same for the atrix hd, thanks in advance.
You need to be running stock recovery and stock ROM to install the update.
The update includes security patches and some modem updates. This update may be necessary for taking the OTA KK update.

ok thanks for answering, i have stock rom so, but unlocked bootloader can i install it then just by installing the stock recovery?
You may need to be unrooted in addition to having stock recovery.
If you removed too many of the att apps, that may cause the update to fail as well.

Did you phone take the update or is it automatically booting into recovery?
The best way to get the update is to flash back to stock ATT 4.1.1, take the OTA update, re-install CWM, and carry on using a custom ROM. This is exactly what I did with a Bell Canada Atrix HD.
You can try re-installing stock recovery in fastboot.

Yeah. The quickest, sure-fire way to get in a position to take the OTA update is to flash back to stock (stock files available here). You can use RSD or MythTools, whatever works for you. Doing this will also put you back on stock recovery.
I had to do this, too, before I could take the OTA. But in my case I had modified/removed too many AT&T stock apps...
thanks to both of you, yes the phone rebooted itself like about 40 secs from turning on i was able to fix this part by formatting cache from cwm, now im gonna try to flash stock recovery

I got a Bell Canada Atrix HD from a co-worker. When I used Myth to flash from stock Bell to stock ATT, it would not work properly. When I used RSD with 98.4.20 without going through Myth, the ATT ROM flashed without any errors. I was able to take the OTA update, flash CWM, and revert to a custom ROM.

does your root still work, did you flash the complete 4.4.4 ftf, that would mean you flashed even the root and your phone is back to stock.
