[Q] Stuck on Sony Logo - Sony Xperia Z Ultra

So I thought of installing a new ROM to my XZU today. First I rooted my device using the following guide : https://www.youtube.com/watch?v=BkQT3nX5yWM. (As I had updated my device to Android 4.4.4 and had .108 FW). I successfully rooted the phone and took a TA Backup. Afterwards, I went on to unlock the bootloader and unlocked it successfully as well. As I wanted to install the ParanoidAndroid 4+ ROM, I downloaded it and got the boot.img from the ZIP file, and flashed it using the Flashtool. However, afterwards, when I tried to go the recovery mode, it is stuck on the Sony Logo, and doesn't blink the notification LED in order to do so.
Did I do anything wrong? I am quite a noob when it comes to XZU related stuff..so I would really appreciate if someone can help me out..
Thanks in advance!
EDIT: (Thought of editing this thread rather than deleting it so that it could be an help for someone who faces a similar problem) I was able to make my device up and running again by flashing the FTF found in this thread: http://forum.xda-developers.com/showthread.php?t=2798690.
Now, I have again come to the status where I have installed a recovery successfully and unlocked my bootloader, and I want to install PA 4+ to my device. Would really appreciate if anyone can guide me on how to do this

It doesn't sound like you did any thing wrong.
Do you have [NUT]'s recovery installed now?
Do a nandroid backup if you do, saves the whole flashing a FTF step if something goes wrong
Did you get the correct PA? what date?
PA should install fron [NUT]'s recovery or you could hotboot the boot.img with flashtool (this wont over write you current kernel) this will let you test if it does work

Thank you. Yes, I read quite a lot yesterday and found out that I have followed the steps properly. So I am wondering if it has got anything to do with the boot.img from the PA ROM?
And yes I did a nandroid backup previously as well, however, I was not aware of how to restore it because I couldn't access the recovery mode. Can I do the restore using the FlashTool? or some other tool in such a scenario?
I downloaded "pa_togari-4.5-BETA1-20140805.zip" available in this link: http://aospal.hostingsharedbox.com/aospal/roms/togari/ . Should I try the last stable release rather than the beta one?
I am sorry for this noobish question, but what exactly is the purpose of "boot.img"? Is it the kernel of the new ROM that I am going to install? or is it something else? I kinda think that the problem might have been with the way I flashed the boot.img previously. I used the option "SELECT SYSTEM TO FLASH" under the fastboot of FlashTool in order to do so. Is it wrong? Should I use the "SELECT KERNEL TO FLASH"?
Thank you again
EDIT: I used the "SELECT KERNEL TO FLASH" option in the Flashtool, to flash the boot.img and I was able to flash the PA 4+ successfully! ..Thank you!

Normally the way to recover would be to flash a boot.img that works and then enter recovery rand restore, easy when you flash the boot.img correctly

The boot image is the kernel and recovery backed into one (it's a Sony thing ) and it belongs on the /boot partition

I think you have figured that one out now :cyclops:. So what you did was write the kernel and recovery to the /system partition, not to where it belongs ie /boot
You can also use the "select kernel to boot (hotboot)" (or what ever words it uses) to boot a kernel/recovery and not change the one on the /boot partition - can be handy at times
I hope that helps you understand some bits about your new Sony ZU

Yep! thanks a lot for your help! Really appreciate it! :victory:

[Q] Flashing CM11/10.2 Problem.

Hi, first of all, my English is bad and i'm a noob at installing custom roms
My HOX+ is rooted and i have the TWRP Recovery installed.
So, i downloaded the newest CM11 Nightly for my device (enrc2b) from the Cyanogenmod site.
When i try to flash it with TWRP it says:
Skipping MD5 check: no MD5 file found
Can't install this package on top of incompatible data. Please try another package or run a factory reset
E:Error executing updater binary in zip ' /sdcard/cm-11-20140902-NIGHTLY-enrc2b.zip
Error flashing zip ' /sdcard/cm-11-20140902-NIGHTLY-enrc2b.zip
I also downloaded a Snapshot version of CM11
It says:
Skipping MD5 check: no MD5 file found
set_metadata_recursive: some changes failed
E:Error executing updater binary in zip ' /sdcard/cm-11-20140308-SNAPSHOT-M4-enrc2b.zip
Error flashing zip ' /sdcard/cm-11-20140308-SNAPSHOT-M4-enrc2b.zip
So finally i downloaded the CM10.2.1 Version
I wiped all cache and data and did a factory reset.
After flashing the .zip and rebooting the phone, but i got stuck in a boot loop (i think) because i waited like 20 minutes but the boot animation didn't change (blue guy with the arrow). Did i do something wrong
I just restored my phone to the backup i made (stock rom)
If you need any information about my phone or something just say it.
I also heard about using CWM instead of TWRP but i don't know how to change it.
PLZ HELP :crying:
CWM recovery
Install this recovery for installing CM.
And don't forget to redo your backup after installing the new recovery before installing CM.

Do you mean with "boot.img" the recovery-clockwork-touch-6.0.4.8-enrc2b.img
This is all i did (i dunno of the screenshot will display i uploaded it as attachment)
I've flashed the recovery.img, thats also the only thing i downloaded on the CWM site.
I also downloaded the Cyanogenmod rom on the CyanogenMod Download site or do i have to download it from the CWM enrc2b Roms?
Edit: I've found out that the boot.img is needed for the device to boot and that i can flash it in recovery.
But is there a special HOX+ boot.img or a Cyanogenmod boot.img or whatever i need? And where can i find it

you can find it inside the rom zip file, just extract it into your adb/fastboot folder and flash it (in fastboot mode) using "fastboot flash boot boot.img". also i recommend (maybe not necessary) using "fastboot erase cache" before and after flashing boot.img.
Also you may need to reflash rom in recovery after flashing boot.img.

Alright i did what u said and i have 1 more question;
If i want to go back to the stock rom, do i need to flash a "stock" boot.img?
Edit: Cyanogenmod is working, i only need to install the Google apps (i think).
Stock boot image
You can flash the Nik3r version to come back to the stock boot image.
And you need to flash the GAPPS in recovery for the Google apps

If you want to go back to stock completely (including relocked bootloader) you will need everything completely stock and matching your phones CID. Of course you will need to flash the corresponding boot.img for every rom. But as far as i know/tried, nik3rs oxp_kk kernel works for all 4.4 roms and the other version works for all Sense5 based custom roms and maybe stock rom (if you don't need relocked bootloader).

Thx, i have installed the Gapps and it's working good.
The only thing i notice is the fast battery drain, is it possible to underclock some thing so the battery last longer, and which apps are good for that?
And if i want to go back to the stock rom, i just have to go back to my "stock rom backup" in recovery and flash nik3rs oxp_kk kernel?

no, oxp_kk is just for 4.4 (kitkat) AOSP like roms. there's another non- kk version which works with 4.2.2/sense5 roms, but i don't know about stock roms. There's also a fallback kernel version which should work with all stock and custom 4.2.2/Sense 5 roms.

[Q] A small question about flashing cm 12

Hi, everyone, I just got my z3 tablet and I am in love with it except i don't like the interface. So i decide to root my tablet without unlocking the bolted and I did made it and i did install TWRP. I have a question, since I have TWRP is it possible for me to install cm 12 rom or I need to have a unlock boot loader in order to install it?
Sorry for my bad english and thank you for answering my questions.

You need to unlock to flash a custom kernel which would be needed by the cm12 to run. So first.
1.Backup drm keys
2.Unlock BL
3. Flash CM kernel via fastboot
4. Flash CM Rom via recovery.

I just bought a Z3 tablet compact, which should be here at the end of next week. I haven’t found a tutorial which includes all steps to get from the standard rom to CM12. Did I miss any steps or does the following steps include everything?
Root tablet on the original Sony rom
Backup TA partition (I guess that's where the DRM keys are?)
Unlock bootloader
Flash a recovery (any recommendations?) I found this tutorial, but I only need one recovery and I don’t want to flash that zip every time I install a new rom.
Flash CM12. Are there any kernels beside that one included in the CM12 zips?

I guess you should just flash the kernel via fastboot after unlocking the bootloader, that would eliminate the need to flash a recovery. It's hitting 2 birds and one stone and besides CM uses a different kernel than stock so later you would really need to flash kernel.
Sent from my SGP621 using XDA Free mobile app
Thanks for your reply. The whole flashing procedure is a lot more complicated than on my S3, so I have a follow-up question.
Should I just backup the TA partition, unlock the tablet, flash this kernel which should give me root and TWRP and then flash another recovery and CM12?
I found this recovery which is only semi-permanent, because you have to flash it before you upgrade/install a new CM12 version. It’s not big deal tbh, but is there a permanent recovery, which I only have to install once.
I'm also curious about this.
Right now, I'm trying to download the Flashtool program from Sony, but apparently, you need to "register" for it. Where did you guys download your Flashtool from?

Correct, make sure the kernel is compatible with CM

The whole procedure is really frustrating, maybe someone can help me here.
I did a backup of the TA partition and unlocked the bootloader. I tried flashing the boot.img from the cm.zip, but I have no idea how to flash the rom via the cm-recovery.
Flashing the advanced kernel to get TWRP wasn’t successful as well. I tried the fastboot mode of the Flashtool and flashed the kernel, but nothing changed.
Can someone post a brief guide with the next steps to get CM12 running (with cmd commands pls)?
EDIT: I just tried to use “adb sideload” in the CM recover, but “adb devices” doesn’t show the tablet .
EDIT2: EDIT: Seems like I got it to work after all. The DualRecover Installer worked, even without SuperSU installed.

I ran into the same problem usin the cm12 nightlies from 27th march 2015:
Sideloading would not work because the tablet is not recognized by the computer. I tried with Windows 7 and gentoo Linux.
Installing from the sd-card in recovery mode was also not possible due to a error of missing "/misc".
I solved the problem by manually choosing the driver in Windows 7. I booted the tablet into recovery. Choose update using adb as detailed in this post:
http://forum.xda-developers.com/z3-...t/root-root-locked-bootloader-sgp621-t3013534
Then I found the device in the windows device manager. Here I manually choose the adb driver that I installed earlier from the flashtool package. After that the device was correctly recognized by Windows and I could Sideloade the cm12 image.

[Q] Root Xperia with Lollipop?

Hi, I'm kind of a noob, so sorry if this is a dumb question.
I just installed the new Lollipop Fimware on my Z2, using Flashtool. Now I want to root the device, but reading through articles on XDA or XperiaBlog, they all said you need to use older firmware. So my question is, can you root the Z2 with Lollipop?
I'd be grateful for helpful answers.

Things needed:
PC, fastboot driver, know how to boot to bootloader(fastboot mode) and recovery mode
Now you can without having old kernel (not firmware)
go to http://forum.xda-developers.com/xperia-z2/development/kernel-andropluskernel-v10-t2974841 extract boot.img from the zip file.
Boot your phone to fastboot mode and in command:
Code:
fastboot flash boot boot.img
Go to recovery mode after restarting and then get UPDATE-SuperSU-v2.46.zip and flash it via newly installed TWRP recovery.

Same here. I'm a noob wanting to learn how to root. But this went over my head :/
Would using PRF creator work? If you bundled the lollipop firmware with supersu.zip and flashed it would it give you lolipop with root? Because this is what i did to update to 4.4.4 with root. For anyone that doesnt know PRF creator is a program which combines 3 files which is are firmware of your choice, a superSU.zip and a recovery.zip. It combines them into a .zip that you can flash in recovery and have the firmware with superSU and a custom recovery on it.
I have a locked bootloader and mines rooted, do you want me to say how?
If its on lollipop, i would very much like to know how.
Isn't this the exact same answer as rooting 4.4.4?
Downgrade to 4.4.2
Root
Install recovery
Install rooted lollipop zip in recovery
If you don't understand this or the method posted above don't root. Also, if.you can't google things like fastboot to understand what it is don't root.

try wiping just "Dalvik Cache" and restart again. I have also face similar strange issue when I was using FlashTool a couple of times.
If that doesn't work try normal wiping from TWRP and install firmware using FlashTool.

I'm no Android/Lollipop/Rooting expert but using an unlocked boot loader I was able to root Lollipop (23.1.A.0.690 ) easily using the kernel from:
http://forum.xda-developers.com/xpe...ot-stock-flashable-kernel-23-1-0-690-t3061816
My steps were:
1. Install Lollipop
2. fastboot flash boot boot.img (to install above mentioned kernel with TWRP recovery)
So far so good.
PS: To use fastboot you'll likely need the drivers from flashtool (http://www.flashtool.net/index.php) and if on Win 8.1 you'll need to search for instructions on how to install unsigned drivers.

[GUIDE] (C6833) (Maybe Others?) New Bootloader + Recovery

Installing the new Sony Bootloader and Recovery
THIS IS FOR ALREADY UNLOCKED DEVICES!
DO NOT TRY THIS ON A GPE!​Since a lot of people seem to have problems keeping their recovery when flashing Lollipop-ROMs i decided to put up this little guide...
You can also Skip this whole guide, by just flashing the newest stock-FW at least once!
First off, as already said, this is for already unlocked devices. You can use this Guide until "Install Custom ROM", except the rooting part, for rooting use this, if you haven't already!
Don't do it if you don't atleast somewhat know what you are doing.
I am not responsible for bricked devices, or whatever you might end up with.
So, lets get started.
1. Download Sonys FlashTool "EMMA" and install it: http://developer.sonymobile.com/downloads/tool/flash-tool-for-xperia-devices/
In the .zip file from the FlashTool you'll find a File "customization.ini"
Copy this file to the installation directory of EMMA, usually "C:\Program Files (x86)\Sony Mobile\Emma"
If you don't copy that file, Emma will ask you for a login, don't create an account there, you will NEVER get any activation-email!
2. Open EMMA and boot your Phone into FlashMode (Power off your device -> Press and hold volume DOWN -> while pressing volume DOWN insert USB-Cable)
3. Emma should now recognize your device, but you have to select it manually tough. Select your EXACT model number. Again, I am not responsible for any bricked devices or whatever you end up with!
Now select the "(Open Devices) TA update" and click "Apply Service"
It should take a few seconds and should then display SUCCESS.
You can now close Emma
4. If you haven't already download FastBoot and Drivers: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
(Run as Administrator!)
5. Download the newest version of twrp and put it somewhere:
New Inoffcial twrp-3.0.0 build by me: http://forum.xda-developers.com/xperia-z-ultra/development/togari-twrp-recovery-3-0-0-t3314440
Old official versions: https://twrp.me/devices/sonyxperiazultra.html
6. Finally boot up you Phone in FastBoot-mode (Power off -> press and hold volume UP -> while pressing wolume UP insert USB-Cable
Your LED should now light up blue
Shift+Rightklick in the Folder where you have put TWRP recovery, and select "Open Commandprompt here"
Now write "fastboot flash recovery FILENAME_OF_TWRP_FILE"
You can now unplug your USB-Cable and boot into recovery and continue from there.
Your recovery will be permanent, meaning you won't loose it or replace with any other recovery that might come with your ROM.
I hope this was somewhat helpfull
Any one can flash this to C6806?

You can try, just select your modelnumber in emma
If the "Open Devices (TA Update)" show up, you're fine. If not just don't do anything.
But do not try this on a GPE!

tried, but no luck. thanks.
It's really weird, I used emma, and installed their latest ta update. Now I can get into fastboot mode, all commands execute successfully, but the recovery never takes. The vol down + Power doesn't work, nor does 'adb reboot recovery'. Am I missing a step somewhere? This isn't my first android device, but from where I sit, it seems like something is up with my xzu.
If I try and install the 14.4* update through emma, it goes through the whole process, completes "successfully", then boots into 14.5. Something is clearly not working here.
The TA update only unlocks the ability to boot to recovery, it doesn't install one. And no, flashing official TWRP to recovery partition doesn't work, it must be compiled again to work on normal recovery partition and not in FOTAKernel, where it must be flashed to work.
Regards

I´m on CM 11 M12 (looking forward to 12) + the new sony bootloader without any custom Kernel stuff.
Sadly, you are right. It´s not done with downloading twrp-2.8.5.0-togari.img and fastboot flash recovery yourfile.img.
The last offical TWRP release for Xperia Z Ultra is from february 2015, any chance they release an updated version for the new Sony bootloader?

I will try to compile one because, you know, summer holidays and no school however I don't know if I will make it.

Is there any (wish for TWRP) recovery for togari, which use the new bootoader?
FYI:
My device is a brazilian c6843.
Emma recognizes the device automatically and indicates with an exclamation point that there is no services available to the unit.
In the case someone doesn't know, it's basically the c6833 with DTV 1seg. It's totally compatible with c6833 firmware, losing TV, of course.
You sir are the real hero! Thank you!
I have a xzu running cm12.1, and I have 2 quick questions for those with more knowledge than me
Is it possible to flash the new bootloder using the open source FlashTool?
If I have to use emma, is it possible to just apply the open device ta update *without* installing stock firmware first?

You can totally do that, BUT, the newest stock firmware also has some firmware updates regarding nfc, also having the newest stock rom flashed at least once will be kind of a requirement to get everything properly working on marshmallow roms.
So I would say flash the newest stock rom at least once!

I followed your advice, but it seems I am missing a few clues.
My sirius was on cm12.1. I backedup and flashed D6543_23.4.A.1.232_1281-5466_R6C.ftf with flashtool on linux. I tried to use emma (several times) afterwards to check for any TA updates, but all I got was "no services matched this device" or something like that. Google tells me I am not the only one with this issue with emma
Then I used fastboot to install twrp 3 from twrp.me to recovery partition, but I could not access twrp.
I fastbooted recovery again with twrp 2.8.7, and this time I could enter twrp and reflashed CM.
Now I can access twrp using the button combinations while booting, but rebooting to recovery from CM leads to a bootloop. Has anyone experienced this as well?
So it seems I am still missing a few clues to using the recovery partition. Is any build of twrp supposed to work on both FOTAkernel and recovery partitions?
Is there a TWRP 3 build that works from 'coldboot to recovery' and 'cm reboot to recovery' with the new bootloader? Any pointers?

Well, booting to recovery on separate partition from os, requires the rom to have a patch... the "new" mm-roms (when they finally hit aka. are ready to be shared in public) will have that, so no worry, just wait.
why it said my phone have no available service, i am on c6833

Hello XDA developers, I'm in urgent and I have a really big problem. It sounds funny but, I deleted my realme ui recovery ,_,
I was trying to install PPUI 4.1 on my Realme 7 but I saw a tutorial that you have to erase the recovery to install TWRP. Please, I need a solution of how can I get it back. I also tried flashing a lot of recoveries and their vbmeta but nothing works. Sadly.
Edit: I'm on RMX2151_11_C.17 | Realme UI 2.0 Latest version

From what I read before, fastboot boot will only boot to that recovery file temporarily but I haven't tried it myself. It should be
Code:
fastboot flash recovery recovery.img
I'm not 100% sure it will work without problems, but if it did, your data will not be wiped.
I suggest you wait for someone else to answer coz I'm not expert. I only learned from guides in the telegram group.

You can try, first, if fastboot works in your device, type adb reboot fastboot, once the script ends, quickly disconnect device from your PC and again reconnect it, you will be redirected to fastboot, if the bootloader is unlocked, you could flash it using fastboot commands.
If you can´t get it to work then you can flash it using SPFT https://spflashtool.com/, put the recovery, in the same folder, with the attached files. All the sources to can use the tool, here https://www.getdroidtips.com/bypass-mediateks-sp-flash-tool-authentication-protection/

Most of the custom roms I've seen requires formatting data. Just to be sure have you unlocked bootloader already? That requires wiping data iirc.
If not then nothing will really work with what you're doing.

What you are saying now is totally different from what you firstly posted.
Installing a custom ROM doesn't require a stock recovery (just in case you are confusing), and obviously, to can switch from a stock ROM to a custom ROM, that has a total different basement, it's mandatory to format data, anyway, you should back up your data previously to do so.

Then you can root your phone 1st then backup your files to a computer and use migrate backup to backup app data. Note that migrate backup is limited to 4gb. Then do the fastboot flash i mentioned before

Why you are saying that you cannot install a working recovery, I don't know of any attempt you did to achieve it.
A stock recovery is not needed to install a custom ROM, and even you can't install a custom ROM using a stock recovery.
If you want to join, flashing your device and stuff like this, better learn how to use SPFT, also you have this tool https://github.com/bkerler/mtkclient, this can save your device, if something in the process goes wrong.

OK, then what you are trying to install is an "old" Android 10 based ROM, if this is the case, then just download a stock Android 10 ROM, flash it through SPFT, then use SPFT to flash the custom recovery, transfer the custom ROM to your external SD Card (preferably) or sideload it, through recovery, and flash it. In the process you need to unlock bootloader, and immediately to flash the custom recovery, boot to it, using hardware buttons.

Alright so, it might sound funny but I think I fixed it. I was playing with my downloaded recoveries until I downloaded the stock recovery, it is compatible but when I do fastboot reboot recovery I get stuck at Orange State for like 30min and it boots me into the recovery so does anyone know a solution for this? And thank you for everything and sorry for wasting y'all's time. Sincereley.

You have to boot to recovery using hardware buttons (PWR + vol. down), in regard to orange state, this is absolutely normal when bootloader was unlocked, it's not an issue but a cosmetic thing.
