Z2 Tablet not booting after Magisk install - Xperia Z2 Tablet Q&A, Help & Troubleshooting

So thanks to Netflix and its implementation of security net I wanted to install Magisk on my Z2.
Im running the stock 6.0 Rom which was just rooted with supersu.
My tab was charged 80+%
I uninstalled SuperSU, went to TWRP and flashed Magisk.
After flashing the screen stayed black. Nothing at all.
Long press power gives me one vibration after 3 seconds but nothing else.
Long press power & vol - gives me the same vibration
Long press power & vol + gives me nothing
Connecting the tab to the computer gives me nothing. No device recognised (no adb, no fastboot)
Connecting the tab to a charger has the LED blinking red.
Long pressing power makes the led turn solid (no blinking)
Power & vol - the same
Power & vol + nothing
Basically I seemed to somehow have turned my tab into a brick oO
I can't even get it to boot to twrp or fastboot
Atm I'm letting it charge just to see if that was an issue (I doubt it)
Otherwise the only thing I can think of is opening it and disconnecting the battery...maybe that will help?
Ok nevermind. I managed to get into flashmode and reflash. tab is now working again!

How did you get it to be recognized and reflash? I flashed mine after rooting and I get similar behavior to what you were getting. It will vibrate once if I press the power button, I can get it to turn the light blue if I hold the up volume and the power button while plugged in. The screen will not turn on at the Emma tool doesn't seem to recognize it.

Same Problem here.

@pseudoheld could you please provide some more info?

[Q] galaxy tab2 10.1 wont enter download mode

I have new galaxy tab 10.1 which I am planning to root, however I cannot get unit to enter download mode. I have tried unsuccessfully at least 20 times using the recommended method of turning the unit completely off then holding the vol-/power buttons. I press the vol- slightly ahead of the power button and hold. All I get is the samsung splash looping over and over with no download or recovery menu icons popping up after the samsung splash. Once I let go, the tab will go into android recovery mode with the option to reboot which takes me to where I started. I have followed all of the tutorials to the tee. Is there another way to get to download mode? Should I take it back if this indicates a more serious problem.
I have also done a factory wipe/reset to no avail. Will vol+ / power do anything?
thanks for your interest I would appreciate any help.

I seem to recall that at least one variant swapped the button around. In any case, it can't hurt to try volume up.
Here's what you do - first, shut the device off by holding power down and waiting for the confirmation.
Then, when it's off, hold the volume down button (to the left side, next to the power button.) Holding that down, press and hold the power button. When you see it light up, release the power button but continue to hold volume down until you see the recovery/download icons.
If doing that doesn't work, try volume up and power. Good luck!
Ill try your suggestions. thank you

I'm having a similar problem. I have a galaxy tab 10.1 wifi that I rooted immediately when I got it. I havn't used it in about 4-5 months. I've already done all the odin and download stuff, but now i want to update my cwm and install a JB rom (I'm currently using aokp). I'm having a funny problem with it now -- Its difficult to turn on and impossible to get into download mode.
In order to turn on my tab, I have to hold down the power, connect the charging cable and get the download screen to turn on, then hold down the power again, wait for the screen to turn off, unplug the power and hold the power button until hopefully it turns on again. And this doesn't always work, sometimes I have to do it a few times. But whenever i've tried do the same thing that gets the tab working normally -- only holding the down volume as well as the power, Nothing happens.
Now once its on and working, things work great, but turning it on is a pain and its impossible for me to bring up the download or recovery option.
I've also tried to 'reboot to bootloader' and that doesn't work, although i can still 'reboot to recovery'
Any tips?

I have almost the exact same problem...
Volume up puts me into download mode and i can connect with Kies but it wont do the JB update
Voulume down ... nothing just boots
if i let it try to do the OTA update it will freeze at the boot screen and stay that way till the battery dies.
To get it to work again i have to do almost exactly what was decribe above..
I have no recovery options at all.
also my Tab is "NOT" rooted

I had a similar problem initially... the screen would just flash the "downloading" message, but the tablet wouldn't mount/connect to my laptop. Here's the solution:
1) launch odin
2) connect usb cable to laptop only
3) power down tablet
4) hold down the power volume down buttons together
5) when you see the downloading message, let go of the power button
6) let go of the volume down button (now just displays "downloading" message, but nothing happens
7) press volume UP
8) you'll get a message about installing custom ROMs and be given the option to do so by pressing volume UP again
9) the tablet mounts and connects to odin
10) from there follow the instructions for flashing recovery via odin (i.e., using PDA button...)
FYI just double check the guides again regarding download and recovery modes. In the thread title you mention Tab 2. This is the forum for the original Tab not the Tab 2. Both devices have different methods and key presses to access the various modes.

Possible hard brick

Hi there
I have recently been given a broken Sony Xperia Tablet Z. When the power button is pressed a red light flashes 3 times but nothing happens. When the vol+ and power is pressed nothing happens. When the vol- and power is pressed the red light flashes three times again.
Is there anything I can do to fix it?
Many thanks!

Hi there!
I've had on charge for a while now and still nothing. Would I need to be able to get into Download mode to flash with flash tool?
Thanks!
After charging the tablet for several hours, do this.
Press vol up + power button and hold until white led blinks 3 times.
(This will make sure the tablet is properly powered off. If after a long period no 3 blinks of white led, then it might mean that tablet state is already off. Press and hold just the power button and see if white led will blink just once then let go power button. The Sony logo should follow. All this is to see if tablet can shut down or power up properly or not. If it cannot do even the basic, then I have no idea how to proceed. This is why I don't trust my important data's in the internal emulated sdcard. I prefer my data to be in removable microsd. If tablet becomes dead and cannot be switched on, then any data that is stored in the unremovable internal emulated sdcard will be trapped. )
If you are lucky, the white led blinks 3 times it means that the tablet can be properly shut down, then ..
Then, connect a usb wire to the tablet. Do not plug the cable to the pc yet. without pressing power button, plug the cable to the PC WHILE you press and hold vol up button.
If you get a blue led at the side of the tablet, it means your tablet can be put into fastboot mode.
Do this first. I believe that once the tablet can be put into fastboot mode, then the tablet can be restored by flashing a recovery boot loader.
If you cannot get the tablet into fastboot mode, then I do not have enough knowledge about how to proceed. You will need to bring it to a service center for repairs.

Hi there!
Thank you both for your help! I can successfully get the device into fastboot mode.
When trying to enter flashmode the device flashes green then goes back to red.
Is there anyway of fixing the device?
Many thanks!
First thing you need is a recovery boot loader.
This link helped me but I use Ubuntu linux to install recovery boot loader into my Tablet z wifi. (I think it is also possible to do it in windows but you will need to install proper drivers)
Before this step, I also used Flashtool under windows 7 to unlock my bootloader. It is not difficult to use Flashtool and unlock bootloader but you must decide how important it is to you to backup TA before unlocking bootloader. In my case, I didn't feel I need SONY bravia engine, so I didn't backup my TA.
1. Use Flashtool to UNLOCK
2. Use Fastboot to install TWRP recovery loader
3. Download a Custom Rom (CM11/CM12/Omnirom./PAC) and save it to microsd
4. Boot into TWRP Recovery, clean data / cache partitions and flash custom rom from microsd
http://forum.cyanogenmod.org/topic/93490-soft-bricked-my-xperia-installing-cm/
To fix the problem, I downloaded CMB from http://forum.xda-dev...d.php?t=2463423. I unzip'd it, and used fastboot to install the boot.img: "sudo ./fastboot -i 0xfce flash boot pollux-windy/cmb/boot.img". Then I rebooted into TWRP recovery, and wiped/reformatted everything (including /data, which CWM wouldn't mount or wipe). I then sideloaded the CM11 ROM, booted back into TWRP, and installed CM11 from within TWRP. I ended up reflashing the CMB boot.img back on, even after installing CM11, and everything seems to be running great now.
Hi, same problem. Good answer was here : https://fr.ifixit.com/Réponses/Afficher/273255/black+screen+and+red+led+blinking+3+times#

Cannot enter flash mode or fast boot modes .(tried to flash stock ROM through flash tool-failed). Only red blinking LED appears when usb cable connected.
Wierd to found when I press hard reset button while pressing POWER button it gives 3 vibes. But nothing changed.
Tried "pressing and holding all 3 buttons (power,vol+and vol-) all at the same time till it vibrates once then let go of the power button and vol+ but keep holding vol - while plugging in the usb cable this MiGHT boot your phone into flash mode" But didn't vibrate while holding all 3 buttons.
Its out of warranty period as well.

Something similar happened to me recently...wonder if this is a bug in a new release or something
This is what I did.
If you can't turn off phone, turn it off using the hard reset button http://sony-xperia.mobi/eng/sony-xperia-z2/231-how-to-do-a-hard-reset-and-reboot-a-sony-xperia-z2-physical-hard-reset-button-sony-xperia-z2.html
There's a really good guide on bricked z2 somewhere on xda but I can't find it anymore . What it said was useflashtools and flash and old ftf e.g. 4.4.4 or 4.4.2 and make sure to wipe apps_log and user_data in settings.
This might also help http://forum.xda-developers.com/showthread.php?t=1849170
Thanks for advice. The problem is it wont connect in flash mode. (attached usb with VOL DOWN button pressed & hold still gives only red blinking led)

If you restored another XZ2 with LOCKED BOOTLOADER's backup you probably killed your phone.
Was your bootloader unlocked?
Restoring anothers TA partition kills your device because drm keys are uniq

Question How to save a black brick

I tried to root my phone by magisk.
After flashing a patched boot.img, it's failed to boot into system and I got a message that "the device need factory reset". I clicked yes and everything seems ok,I can boot into system. Then I tried to flash img again. So I boot into bootloader. Unfortunately, this time I got a black screen. The phone doesn't response me anymore.
I tried the software repair in xperia companion but It cannot dected my phone when I hold on volume down and plugged in it. I also tried hold on volume up + power but nothing happened. Hold on power key also no response. The led light always black, only become red when I connect it to my pc.
What should I so now and what's my phone's status? I searched something about 9008 mode and edl but I don't know how to check whether my phone is really turn into that status, my pc cannot dect my phone.
Have the same problem, only with the 5 iii instead. Still looking for a fix.
Try to switch the phone off; then just plug it into your PC without holding the Vol- key. It has happenned a couple of times with me that the phone does not want to boot up, with attempts to get it into FLASH mode by holding the key down throwing more confusion into the mix.
I think there is a low battery protection. Make sure the phone is charged up. Keeps the device from death during a flash.
Red led mean a very low battery. Keep it plugged (not to PC but to power adapter) for 2-3 hours and then try again a force reset.
Never, never try flash or other stuff under 50% battery
Also force restart is keep pressed vol+ and power button (or vol- and power button) till you fell a vibration.
Try this after a good charge

It might require experimenting with service modes and different chargers. I had an early Xperia 1 III that bootlooped while charging after setting up the fingerprint reader. It seems that charging is disabled during booting. It has to finish or enter a service/fault mode.
my phone is having this after doing fastboot --slot=b reboot recovery (which actually I had to do fastboot --set-slot=b and then fastboot reboot recovery). the notification light blinks red. have tried vol up + power, vol down + power, and vol up + down + power for like 30 seconds and nothing

I feel sorry for you brother...such a nice device...OK let's talk what happened, the state now your device is in is called hardbrick and it had a corrupted bootloader or no boot loader, but your device is still alive, in your PC in device manager it lists as Qs USB mode with some number after it like qsusb9008...now this device can only be brought to life with the help of a blankflash file which can flash your boot loader in snapdragon service mode...actually no snapdragon can be hardbricked permanently now you need appropriate blankflash file for your device.. Please don't open the device if some repairmen suggests to do JTAG nothing is necessary all you need is blankflash file which is shared to only Sony testers groups.... Who tests ROMs before release and they hardbrick so they share those files to them.... Please don't loose hope....it takes time but certainly it can be bought back to life... And dont try any flashing utility as there is no functional boot loader on it now and nothing will work...Sony won't provide that for sure and they will say then can only solve by mother board replacement ,don't believe therm your device is perfect it only needs blankflash file as it entered into final safe mode... I ain't regular on XDA if you need any info contact me via my mail [email protected] g ma I'll .com
Have any of you tried this - https://developer.sony.com/develop/open-devices/get-started/flash-tool/download-flash-tool/

Restart Without Power Button

Hi.
How can i Restart without Power button?
Volume Down and Bixby together to download mode and then Volume Down does not boot up the phone, it just goes back, it does not restart.
Any tips? I Fixed my initial issue, but now when the battery discharged and the phone turned off I cannot start it.
Should I flash it again (that is how i fixed my original issue, of not wanting to boot up) Used odin and the lastest firmware files to load and then when it completed it auto restarted.
Is there a quicker way?
Replace the power button assembly...
^^ nah.....
I got it, Volume Down and Bixby, connect charger, brings the download mode, hit Volume Up, connect to PC open Odin, load empty AP ("xxxx.tar") Make sure your phone is connected, start, phone restarts.
