[Q] Recovery mode not working - Xperia Tablet Z Q&A, Help & Troubleshooting

Hi
I'm newbie to Android custom firmwares and I was trying to install a custom firmware, following a tutorial on the web, but i'm stuck with a problem about the recovery mode.
Developer Options enabled.
USB Debugging enabled.
first i tried the hardware method Volume Down + Power Buttons combination but i get the safe mode and when i did it again it started in normal mode.
trying the Quick Boot then ROM Manager applications didn't work
trying the computer method didn't work too
Code:
adb reboot recovery
any help please.
my Sony Xperia Tablet Z WiFi is rooted and unlocked and i have these system applications installed:
Online Nandroid Backup
Nandroid Manager
ROM Manager
Quick Boot
SuperSU
Model Number: SGP312
Android Version: 4.2.2
Kernel Version: 3.4.0-g7eaf37a-01078-g2ebac89
Build Number: 10.3.1.C.0.136
Thank you

The Sony Xperia devices does not have a built in recovery, you need to install it yourself, either with a root process or just installing a stock based kernel that have it built in. And the method to make it boot in recovery are snapping the volume up button while the Sony logo is on screen.

No. Now you need to install the recovery, check Android dev section, and look for Phil's recovery...

[Q] Broken Recovery/Bootloader

hey ladies and gentleman - best regards from germany
im wasted. and it would be nice if you can help me. because of a ****ty microphone quality, i´ve installed this in version 3.15:
http://forum.xda-developers.com/xpe...m-existenz-ultimate-1-0-5-light-dark-t2835196
But the quality wasnt better, though. imo it was the existenz rom so i tried a different one.
yesterday i have installed a cm11 version in which some functions of my z2 wont work. :crying:
so i have seen that there is a 4.0 version of existenz, downloaded it, put it on my sd and started in recovery.
but my twrp was gone and cwm was installed
what the..? okay, tried to flash it anyway but it was stucked before AROMA was started.
copied the .zip from sdcard to internal to provide that there was an issue with rights or something.
but no chance.meanwhile my cm11 is working, but even PLAY-Store Apps like goomanager or RASHR and TWRP itself wont install
twrp. im using a windows 8 pc and have some trouble to use adb or odin.
when i try to boot into dl or rec mode, the led stucks either orange or blue.
do you have a clue what i can do? pleaaaase :crying:
Ok first.
Disable driver signature autetification on win8/8.1
Install Sony flash drivers
Install flashtool
Reflash with stock rom
Sent from my C6903 using XDA Free mobile app
You obviously have unlocked bootloader so...
If you still have recovery, just install another kernel with twrp, like Doomlords Kernel. This is a stock kernel with cmw, philz and twrp. Once this kernel is installed cm won't boot anyone, but it will allow you to install a eXistenZ.
If you don't have recovery download Doomlords kernel and flash the boot.img ( i think it's)
Code:
adb fastboot flash boot boot.img
Reverting back to stock 4.4.2 to fix your issue is a waste of time.
Okay, at first thanks electrash for showing me how to use flashtool on windows 8.
Has worked so far, im running on stock rom but cant reach the bootloader or recovery.
the LED is not blinking and i have no chance to reach the recovery mode.
is it possible to flash this with flashtool,too?

When you say download mode do you mean fastboot mode? Plugging in the Usb and holding volume up when the phone is off? If so yes.
The light should remain blue and, assuming you have the fastboot drivers installed, you can flash things.
hey guys! my phone is workiiiiing
you´re the best ,seriously!

Need help to resolve issues in my Xperia Z2 after root

Hi
I am having some issues with my Xperia Z2 D6502. I am new to rooting, so please bear with me.
I rooted my device following these instructions. All things went smoothly. However next day I started having problems to boot into recovery mode. I have explained my problem here. I tried reinstalling Z2-lockeddualrecovery2.7.154-BETA.installer which I got from the above instructions. It installed successfully but still I couldnt boot into recovery mode. The phone even stopped detecting my SD card, I had to reinsert it each time I would reboot to make it work.
So I followed all the instructions from the scratch again except for the last one which involved flashing pre rooted 5.1.1 stock ROM(flashable_D6502_23.4.A.0.546.zip). I wanted to keep rooted kitkat 4.4.2(I initially,i ..e., before rooting, had 5.1.1 but according to the instructions I had to downgrade it to kitkat) which I obtained as a result of downgrading my Xperia Z2 from 5.1.1.
Now I am facing wifi problems with kitkat. I can connect to the network but internet works extremely slow while it works absolutely fine on other devices. I dont have access to the router as its a common router in my dorm. I tried several solutions which I found on internet involving changing DNS to 8.8.8.8 and changing IP settings to static. None of them had any effect. Is there anything else I could do to resolve this issue?
The main reason I want to keep kikat is that I want to install Xposed on my device for imei changer and android id changer, and I read somewhere that for installing Xposed on kitkat you dont need to flash any zips and just install it like any other app. I didnt flash it on lollipop because of the warnings about getting stuck in bootloop in sony devices and I wasnt sure of how to flash it as the instructions were not very detailed and I am new to it. So do we flash it the same way I flashed 5.1.1 rom, i.e., booting into recovery mode and then selecting install and then selecting the zip I want to install?
I got this link to working modules on sony devices but I cant find imei changer in the list. So even if I installed Xposed, with your help of course, will I be unable to use imei and android id changer?
I read in several places that I should backup my device so that I can restore to the previous state in case I soft brick it or enter a bootloop. What kind of backup is this and how do I take it?(I googled and found Backup TA to take backup but I am not sure if that is the type of backup I am looking for and the instructions in the page are not detailed enough for me as I cant risk my device.)
I have one request, please provide me with detailed steps as I am doing all of it for the first time and am extremely nervous of screwing up my device as it is my only phone and quite expensive too.
Well, my device is rooted, on 5.1.1, and Xposed Works very well, without bootloops, and all Modules that I tried worked very well, by your description I can't figure out what is causing your problems...

If you got a boot loop, you can:
1: Force power off the device by holding volume+ and power button simultaneously, then, you will able to flash via flashtool a new ROM
2: if you have a custom recovery, you can follow the same method to power off, then, power on and access the recovery, where you will be able to flash a zip containing a new system, etc.

Do we make custom recovery using the backup option we get when we boot into recovery menu?
And how to enter recovery menu without booting into the system? I access it using NDR utils app.
And do I need to flash any recovery zip from the recovery menu if I want to keep it?

If you have Dual recovery, you are already running a custom recovery.
to enter the recovery menu whitout boot the system, you should:
Power On the device, and at the FIRST SONY screen, when the LED flashes, press volume up to enter TWRP

Volume down for TWRP, volume up goes to the other one, CWM I think? I've never looked!

The DRM keys are unlikely to affect your warranty claim but they do other things including allowing your device to get OTA upgrades.
To unlock your bootloader you have to get an unlock code from Sony, to do that you give them your device details. So if you send it back for warranty and they look it up, I have no idea if they do, they'll see that you have unlocked your bootloader. Or at least got the code to do so, I doubt anyone gets the code without planing on using it.
Those DRM keys play a role in the Sony image processing for both the camera and the Bravia Engine. That is what you lose by unlocking the bootloader, warranty is not the major factor.
Hey
I had the same problem.
So what I did to solve this?
I did a factory reset > flash again flashable_D6502_23.4.A.0.546.zip > wipe dalvik >
And the problem was fixed.
Good luck

[Z2,Z3] Root and recovery stock 5.1.1 264 ROM no data loss - proper easy way

Rooting and romming Sony devices is a little harder than most android devices, some things work a little different. The scattered info doesn't make this any easier either. I had to find this out the hard way, softbricked my Xperia in the process, but I finally did it. I see that there still are people that wish to root stock 5.1.1 and that there are no unified proper instructions to do this so here is my process and guide. Good luck.
There are many ways to do this, but it includes flashing your Xperia to earlier firmware then rooting and installing the recovery and then flashing back the newest firmware, so I made this little guide to make things easier for Sony newcomers. This process should be compatible with Z1, Z2 and Z3(c) - but ofcourse its made for Z2, for Z1 and Z3 download recovery files for your model respectively.
You won't loose any of your data on your stock ROM if you do this correctly.
You'll need a Windows PC, 7, 8.1, 10. (Mac and Linux are also supported)
1. Root your Z with Kingroot.apk v4.6 and v4.8 work flawlessly. Just download and install as normal apk and hit the big blue button. You have to have internet connection for this to work. It will root your Z automatically after cca. 2m.
Kingroot app is basically a super su app from a different developer. Congrats, you now have root.
2. To install a recovery do not use any flashing apps by TWRP or similar, it wont work. We will use XDZR.
XZDR is Xperia Z Dual Recovery, its basically Philz recovery and TWRP recovery flashed together. You enter Philz holding vol up and TWRP holding vol down when powering up your xperia. * Search for NUT's dual recovery for more info.
Download the recovery from here:
http://nut.xperia-files.com/path/XZDualRecovery
(Download the correct .zip for your Xperia model).
3. Download the. zip to your PC.
4. Connect your phone via USB after you have enabled USB debugging on your xperia. If you have correct Sony drivers installed your PC will recognize your device and a dialog will pop up on your phone (about allowing USB debugging from this PC). Allow the access.
5. Unpack the zip you downloaded to a random folder on your PC. Here run the install.bat if you're on a Win PC. Bat will run and here you just choose the first option, type 1 and follow the on screen instructions, keep an eye on your phone, it will pop up a couple of yes - no dialogs. Allow the access and ADB access and wait, it will be fast.
When you reboot you will see a green LED light up while SONY splash is shown, this is when you hold up or down for one of the two recoveries.
Down is for TWRP and up is for Philz.
6. Download superSU from here:
https://download.chainfire.eu/696/SuperSU/
Boot to system again and now you can unroot your phone trough Kingroot app (general settings) and then reboot to recovery again and flash the file from this link, you will get the super su app and super su binaries and this way you're fully rooted and will have dual recovery for your full flashing pleasure.
* Remember that you first need to unroot and uninstall Kingroot app and then flash Super su, otherwise you risk a bootloop or just not functional root access.
* Do not flash newer TWRP or any recovery or youll loose your recovery.
* I am not responsible if something goes wrong with your device.
And thats it, you have your data intact, stock 5.1.1 ROM, fully functional root access with super su and two recoveries, intact BL and DRM keys and you can flash almost anything that supports LB (locked bootloader).
Hey.
I have a few questions.
Does installing recovery void the warranty? Can the XZDualRecovery be uninstalled easily? Can I still update to Marshmallow via official update when it comes out when I have recovery installed on my phone?
Thanks!

I think that Sony does void warranty if you do an "unauthorized software changes" and changing software in any other way than trough OTA is unauthorized by Sony, so yes. But you can completely restore your device to factory state by flashing an official FTF image trough flashtool and restore Sonys recovery and basically get your warranty back.
If you follow the above steps installation of XZDR is quite easy and fast.
You will be able to update to official MM by flashing MM FTF image trough flashtool and restore your phone to "official" software state. But with XZD recovery you will be able to flash leaked MM from beta program even sooner and easier.
This guide does not unlock your BL and does nothing irreversible to your phone * providing you do everything correctly.
Thanks for answering! Much appreciated!

Rooting with this method wont unlock your boot loader so there is no need for that, your DRM keys wont be touched.

You can leave it as is, you will have full root functionality. Of course you can also update binaries to have up to date bug fixes and security patches, update trough normal method works fine.
@5ageman Hi. Thanks for the tutorial. I m a noob in this rooting stuff. Last night i rooted my phone Xperia Z2 5.1.1 using kingroot bcos i was scared of rooting with some other steps and bricking my phone. But then i realized that xposed wont install unless i have custom recovery. But i m quiet confused with few things related to root even after reading so many posts. So just need to know what exactly recovery is. Like when i restart my phone and then press vol up or down key what will exactly happen? Is this something like safe mode and some other mode in laptops??

Recovery is actually closest to BIOS in PC terms although its much more. Xperia Z2 has no recovery by default, you'll need to flash it manually. See step 2. And only then you can eter recovery. By pressing vol down when the green LED lights up you will enter TWRP a custom recovery made by Team Win Recovery Project. Nothing will happen if you do nothig, you wont accidentaly wipe or brick your Z2. If unsure what to do next just tap the reboot button and then system to reboot to system as nothing happened. Go step by step, no hurry.
@5ageman thanks alot for ur answer. Now my doubt is clear.
But i have few more questions related to ur tut.
1- i have already rebooted my phone a number of times after rooting it. Like for some other purpose and not for recovery or super su. So will the tut work for me as i read somewhere that one need not restart the phone after rooting using kingroot and install recovery directly. Or if it was for some other device i dont remember.
2 - According to the end of step 5 and step 6, does that mean that i have to download super su from chainfire while i m still in recovery mode? And once agn in the system after uninstalling kingroot and rebooting in recovery do i have to install SuperSU in the recovery mode? If yes then how?
3- last question. Entering recovery is just vol down button or power + vol down both.
Once again sorry for such basic questions but i m completely new in the world of rooting plus i want to make sure i know what i m doing.
Thanks for ur patience. Appreciate.

1. You cannot install recovery directly from the system on Z2 like on other phones, Z2 has no recovery partition. This can only be done with unlocked bootloader. Just make sure you have a working root access with Kingroot and USB debugging enabled when you connect your Z2 to a PC.
2. Download superSU from chainfire while still in system, then reboot to recovery and flash it trough recovery. It's a flashable zip. Before booting to recovery unroot your phone trough Kingroot app. SuperSU zip will flash su binaries and the app to system partition automatically and will root your phone again. Rooting trough Kingroot is done only to flash the recovery, then its deleted.
3. After you successfully install tge recovery when you power on your Z2 it will vibrate and flash green LED on sony bios logo. Then you hold down vol down key until led flashes purple. Afterward it will boot to recovery.

1- no i didnt mean in the system. What i read was that when u root with kingroot u r nt suppose to reboot until u install recovery. Otherwise it might cos prbs and nt install SuperSU.
2- What does flashable exactly mean. Is it nt just installing? I dload the superSU from chainfire while in the system and install in the recovery, right? Where will i find the zip to install it? (sorry... Had to ask)
3- i think i got that...i ll knw that exactly when i try it...lol

1. You wont face any issues if you reboot, but you dont have to. Just plug your phone to PC while your phone is in android. Yes you download in system and then install - flash in recovery by tapping "install" and then you navigate to supersu.zip and select it and then swipe to flash it. The supersu.zip will be there where you download it, most likely on internal storage in download folder.
2. Flashable means its installed trough recovery - its flashed as opposed to being installed normally in android system.
So is it safe to root my Z2 with this? I have 15.1.1 264 stock rom, is this safe?

Flashing a ROM

Hello,
I started on a quest last week to try and make my long forgotten Xperia tablet z LTE SGP321 more user friendly.
I stopped using it after being frustrated by the bloatware and its lack of customisation.
So I thought flashing a custom rom might help and wanted a bit of a technological challenge. Boy do I feel like I've got one.
I used kingroot, which worked fine. I tried to install SuperSu but it wont update the binaries.
I've managed to unlock the bootloader (forgot to do the backup TA woops!).
I downloaded TWRP app, flashed pollux_windy to recovery. Now there doesn't seem to be a combination of keys that I can find to boot the sony xperia tablet Z into recovery?? Power and volume up or down or jamming both keys...nothing seems to work. I've found one forum post suggesting it isnt possible and that I need to flash a kernel which is where I'm getting stuck.
SO this is where I am now and was wondering if I should use CWM instead or if there is another way to open recovery?
My main aim is to completely clear the tablet hard drive and start again with a custom rom.
Thanks!
>>>>>>
NEW info
So i've managed to use the ADB to reboot into the boatloader. All that happens is a black screen. I want to try and flash CWM or TWRM but it doesnt seem to work.
Im beginning to think there's something strange about the sony xperia tablet z in that it doesnt have a bootloader in its stock firmware. i've seen something about using a Kernel approach but the guides are unclear.
Any help on flashing a CWM or TWRM into recovery would be much appreciated!!

Thanks for your help. I thought I'd start simple and just try and flash TWRP to recovery.
i downloaded the latest TWRP pollux windy img and then used the command fastboot flash recovery twrp.img
It says FAILED (remote: command not allowed)
adb fastboot devices displays my tablet
(by the way in configuration in service info it says bootloader unlocked: Yes)
>>>>>>UPDATE
so i managed to flash a cyanogenmod img using "fastboot flash boot boot.img"
The device then soft bricked and went into a boot loop. Is this because I used the wrong version of cyanogenmod?? Any other I can try that work?
I panicked a bit, mamanged to get the tablet into fastboot somehow andthen flashed a TWRM img to the boot using the same command above which now loads TWRM.
fastboot reboot now caused the device to go into TWRP but its in recovery mood
How can i undo that step i did when I flashed the boot img of the cyanogen mod. I want to put the old boot.img back!

also can I ask another quick question of you, what do you do to boot into recovery on your xperia tablet Z device?
Thanks!
Sorry about all the updates.
I decided to see what you had installed on your signature and tried resurrection remix. Version 5.8 caused Error 7??
So i went for version 6.9 which i installed successfully.
Only way i know how to get into recovery is to use adb terminal command "adb reboot recovery"
Also before I installed resurrection remix would you recommend a complete wipe of everything or does it not really matter?
Thanks and hopefully that's me all sorted!
Use VOL+ or VOL- on boot to enter recovery.

2 way for me:
- usually you can set an "advanced reboot menu" under developer option or the ROM customization panel (depends on which ROM do you use)
- turn off your tablet, now push the power button until your screen just turn on, leave the power button and start pressing vol+ and vol- alternately until you boot into recovery

Xperia tablet Z won't boot into recovery after latest ROM

Hi there,
I realised that after the latest Resurrection ROM update that Magisk Manager was not installed anymore. I went to install and I need to get into TWRP to flash it. However, the Fastboot app I downloaded now says that the app doesn't have root permission. I am then stuck in a loop where I need to access TWRP but I cannot anymore.
What am I missing? I believe it may have to do with the fact that Magisk is not running - but I cannot install it unless I get into TWRP - if not mistaken?
My understanding is that you cannot go into recovery mode by holding on + on this tablet - am I correct?
Thanks!
Tony

There is no stock recovery on Sony devices like TabZ. You'll have to install one bundled with kernel or a separate one, to use TWRP.

Hi there,
My Z was on Resurrection already and I could get onto TWRP by using one of the many fastboot app and select "reboot to recovery". After the last update, I lost that ability, those apps say the device is not rooted.
Sorry for not being too familiar with the procedure: what do I need to install now? I am kind of confused, the device is/was rooted already and TWRP was already installed. Are you suggesting that when I flashed the updated ROM I lost TWRP?
Thx
Edit: I've got in! Trick is: power on, wait for the purple light and click VOL+ ONCE. I'm in TWRP now. THank you.
