[Q] Boot loop after custom bootloader install - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Hey folks, last night I followed this guide http://forum.xda-developers.com/showthread.php?t=2708194 to get a custom bootloader installed on my tablet. Unlocking the bootloader was a bit strange, but worked. I downloaded the bootloader for the SGP511 wifi-only model and installed it without issues. After that, I rebooted and was stuck in a boot loop. The device starts by displaying the logo, then turns black and vibrates periodically a couple of times, then reboots and does the same over and over again. I had the device plugged in allowed to run for at least 45 minutes to see if it would help, but to no avail.
I can access the custom recovery included in the bootloader just fine, but the OS doesn't seem to like the new bootloader. Anyone know of a solution?

You didn't read properly.
You have the new .402 firmware on your device, and the custom kernel / recovery is only compatible with .36 and .55 firmwares. (Doomlord is working on a new version, so just wait a few days.)
Press Volume-Up + Power for a few seconds (device will vibrate 3 times or so) to hard-reset the device.
Then flash a FTF of the .402 firmware with the xda Flashtool (not the Sony Flashtool) to restore functionality.

That worked like a charm, thanks a million and sorry for not reading the instructions properly!

X10 Bootloader Unlocking Problems

Uh, so I've been having a few problems trying to unlock the bootloader on my X10 and I came to some problems:
1. When I first connected my phone with the USB cable, the FlashTool showed that my phone had debugging mode off even though I checked it and it was on!
2. I ignored this problem and decided to try unlocking the BL anyways. When I shut down my phone, held the back button and plugged the USB cable to put the phone into Flashmode, after 10-20 seconds it would automatically reboot itself and get my phone out of Flashmode, making me unable to flash Kernel Downgrade!
3. This time I trained my fingers and tried to flash Kernel Downgrade before my phone started to reboot itself and I succeeded. But now that I flashed it, the next step for unlocking says
"disconnect usb cable, press power button until phone vibrates shortly and immidiatly connect the usb cable again (it is supposed to be stuck at SE logo)"
but the problem is that my phone won't go anywhere after the Sony Ericsson text (not the logo with the circle and stuff where it's supposed to)
I am using (or at least was using until I flashed Kernel Downgrade) DoomLord's Kernel v6 and ViolentOS ROM. I have also tried restoring the xRecovery backup I made exactly before starting the flashing, but it still won't work, the phone always gets stuck on the Sony Ericsson text. What am I supposed to do?!
What logo with the circle?? That's the boot animation, loaded when system is already running. It is supposed to be stuck at the first screen, that's when system starts loading kernel and can't with "wrong" baseband.
Sony Ericsson text is WHERE it has to be stuck.
Also, at least for me, I couldn't do unlock without 2.1 rooted system installed, had to flash baseband and system, then unlock and then restore my 2.3 backup.
New Problem

@kalte The logo with the circle is the animation that comes after the text.
But forget what I said. I'm trying to boot the phone and it's not working. I disconnected the USB and took off the battery then put the battery back in to see if it could boot. It's stuck at the text even though I restored everything with an xRecovery backup. Is this because of the Kernel Downgrade?
FIXED IT!
I'm such an awesome person! Just had to flash the Generic Kernel Upgrade. Everything is working, with my previous settings and all.
Tried Unlocking X10i .. getting stuck at the SE logo

[Q] Xperia P stuck on boot

Hi,
Hope someone can help. I've tried to install a custom ROM today and I'm afraid I managed to brick my phone (Xperia P). Here is what i did:
I started out according to the Starters guide:
-Rooted phone
-Installed CWM
-Made a backup
-Unlocked Bootloader
-Installed JB Moonbreaker 3.5: at this point I was actually still following the starters guide, as in: wiping cache, wiping data,wiping dalvik cache and then installing from zip.
-The phone is currently stuck on the loading screen that comes after "Sony" and "Xperia" (the colorful swirling thingie)
-I can only shut it down by pressing and holding the power and volume up keys until it vibrates 3 times in a row.
-Starting with pressing volume down key repeatedly will not bring up CWM (also gets stuck on the same screen).
-Will also not fastboot anymore properly. (waiting for device for "fastboot.exe -i 0x0fce getvar version"; LED on device will not even light up as blue, goes to green instantly)
-In Device Manager I can see it as "Android" with a yellow exclamation mark.
-Sony PC Companion gives me the "My Sony Xperia P LT22 is connected" popup every 15 seconds but will actually not show the device as connected
I'm wondering if I can flash a stock rom on it to recover it or if there is anything else that can be done.
Thanks in advance

Keep the stock fw ready to be flashed using flashtool, enter into flashmode and flash it !

Can't seem to get it flashed from flashtool. I'm pressing the back button and connecting the USB and I'M just getting the same stuff on the phone, while flashtool is waiting for the phone.
I did manage to enter fastboot again though. Should I be flashing CWM from here (since I can't enter it). Or kernel then rom? I'm a bit lost.

Its volume down key and Plug in USB, to enter flashmode
Not back button.
Or flash a kernel by fastboot mode, enter CWM and install the ROM (assuming you have the zip file in the SD card )

No luck. I get a green LED and nothing happens. If I hold down volume down for really-really long then I'm back to the same boot animation.

yes green LED it is,
i hope you had the flashing process ready at the PC right ?
First make sure your phone is shut down. long press power+vol up until you feel 3 vibrations.
From there you can try fastboot mode or flash mode.

Alright done all that, still is the same. I've started to play with other USB ports and I noticed that when I get connected it tries installing the SEMC Flash device driver. It fails with "device unplugged" message exactly at the same time when when the Sony logo appears. Then it tries installing MTU USB Device as well. Reinstalled flashtool drivers and tried in different ports. It seems as if the phone is not staying in flashmode?

I recall I had that issue with wundows 7 at the beginning, what I did then was to boot my windows xp and managed to flash from there.
I have tried many things since, and if I am not mistaken it's installing flahtool drivers that fixed it finally.
I think there are 3 drivers there you need to install.

you can use emma flash tool by sony to flash your device once u get into flashboot mode(vol down den insert usb cable)
you will find it at sony developer site
did you tried to flash the rom over ICS, if yes then thats why your p got stuck at boot, coz i too got the same prob, when i tried to flash the JB moonbreaker over ICS, so what i did was pressed the power button and volume up button till 3 vibration, start flashtool and flash stock ICS firmware, but don't uncheck wipe data, otherwise you will get bootloop, after flashing is complete, now download and flash stock JB firmware, root your phone using doomlord's easy root kit or any other way you know, install cwm and now reboot into cwm flash JB stock or custom kernel and then the rom, thats it, just let me know if the prob is solved, thanks

Xperia P PAC rom jb 4.2.2 user
hit thanks if i helped
Thanks everyone for the input, issue resolved, kernel and rom flash was successful.
Stuck on boot
Guys I have the same problem.
I wasn't satisfied with the rom I put on my phone so I went on to put another one on it.
Flashed the kernel with fastboot, went into cwm, deleted system, cache etc. and went on to flash the rom, but there was no rom zip there, and I was sure I had put it. It was probably an error during the copy procces and it just stopped, I assumed it copied.
Well, now it is just stuck on the boot screen. I can get into fastboot and cwm, but I have nothing to flash.
I tried using the Sony recovery "Emma" but it just stays blank when I connect the phone..
Is there something else I can do?

Hi
I think im facing a very similar issue, i m very new to this and therefore didnt understand the solution. I did visit the developer site for emma, but can you tell me the exact thing to do after starting Emma. I mean, when do i connect the phone and how, what commands to give. Below is explanation of how i got into this and what all ive tried.
OK i ve been trying to flash a new custom rom on my Xperia P, i looked at a number of guidelines and doing things step by step.
Since im very new to this i downloaded a few Roms. I was following the guide "http://droidors.com/2014/07/08/update-xperia-p-lt22i-to-android-4-4-4-kitkat-with-slimkat-custom-rom/2/" and everything was going fine. I reached the step to "fastboot flash boot boot.img", i did that and then went on the next step to boot in CWM Recovery and install the zip rom and the Gapps. During the Zip Rom install i got status 7 error.
Now, i noticed that i might have flashed the wrong Rom so rechecked the guide and installed the correct Rom which is mentioned in "http://forum.xda-developers.com/xperia-u/p-development/rom-slimkat-4-4-2-release-candidate-t2657795" . But now THE PROBLEM IS, AFTER I FLASHED THE INCORRECT IMG, MY PC IS NOT RECOGNISING THE XPERIA P SAYING IT DOESNOT RECOGNISE THE DRIVERS, therefore im not able to copy the ROM Zip on the SDcard, to then run it from CWM.
After sometime i tried the below
Ok, now i tried to flash the stock Rom through this link "http://forum.xda-developers.com/xperia-u/p-development/ftf-firmware-xperia-p-generic-world-t2322163", through flashtool to bring my phone back to life. I installed the drivers as per instructions from drivers folder, but for some reason the pc is just not accepting. I did install through this exact method yesterday night and it worked perfectly.
Please suggest. I hope im asking at the right place.
Urgent help please
I forgot to mention, after I flashed the SlimKat Rom, and things went out of hand ( till this point i could see Slimkat logo at boot and could also go in CWM Recovery ), I tried to restore through Nandroid Backup i had done. As soon i selected the restore option and then the backup file, within 2-3 seconds the phone went off, and then on boot all i can do is see "SONY" on screen. Nothing else happens.
I ve tried all this on a different machine, with different wires and different USB port, no luck
Kindly advise, im stuck with no spare phone.
Solved i guess
OK Brother,
I downloaded EMMA and am currently downloading the service. It is very self explanatory. What was amazing is when i recognised my phone "What a sight "
Flashtools wasnt able to do that, so i guess the manufacture tools are damn important ( i wasnt exactly of the opinion before )
Also it is downloading Android 4.0.4 Build 6.1.1.b.1.54, which first came on the device, which also makes me think may be i should have tried that rather than trying to flash with the JB Rom all this while.
Man, i was scared. Thanks for this thread Bro.
God Bless
Will inform once the phone is booted up to confirm it worked.
Emma Worked
OK guys, I can confirm its EMMA "Flash tool for Xperia" fixed the problem for me. It installed 4.0.4 on it.
Also there is a pdf in the Download which guides about the usage.
Sigh
Correction- it installed the latest stock ROM jb

[Q] Bootloop w/ black screen Xperia Pro

Okay, I know answers to my questions have been answered already, but this CF of different problems is too much for me to solve by myself, so please bare with me.
First of I should mention that it was possible to unlock the bootloader on my Xperia Pro before, but since unlocking the bootloader, rooting it and having trouble booting one custom ROM I flashed a (sort of) stock ROM using flashtool and after that the bootloader got relocked and now it says it's not possible to unlock the bootloader. It's now unlocked but I can't boot into fastboot.
With thousand-yard stare after 7 or 8 hours of sleep deprived studies in the subject of rooting, custom ROM's, bootloader unlocking for the third night in a row I believe I accidentally flashed a 4.0-kernel when I should have flashed all 4.0-based firmware not just the kernel. I had stock Xperia 4.2 firmware when I flashed the 4.0 kernel.
Now, based on the LED, it won't start normally. Plugged in to a computer it (based on the "Found new hardware"-sound in Windows) starts booting but the screen remains black. Based on the USB-device unplugged-sound it turns off and reboots and so on. If I boot it up in flashmode it's just about the same story. If I try to boot it into fastboot Flashtool identifies it as in flashmode not fastboot, as mentioned above. As I understand it the phone actually boots into fastboot but the computer doesn't recognize it as such.
Anyways, it stuck in this bootloop, the screen never lights up and it doesn't start unless a USB-cable is unplugged. It's not a problem with the battery. I've got two batteries and one more mk16 that I've tested both batteries with, so I've eliminated that possibility.
I've "successfully" re-flashed it with stock 4.2 firmware with Flashtool. Still bootlooping. I've "repaired" it with PC-comparison a couple of times and it says it's successfully updated with the latest firmware. Still bootlooping.
Since the screen is black I can't know how far it boots or anything.
So: Black screen, boot looping, stock 4.2 firmware, won't start at all without being connected to a computer, boots up into flashmode but not fastboot.
I'm a total n00b at all this. No experience with Java or Linux. I'm partially working side-by-side with my brother with some programing skills and a lot of Linux experience, but no experience with Android at all, so I'm sorry if I/we can't provide you with adequate info or answers.

[Q] [HELP] Have I hard-bricked my brand new Xperia Z2?

Okay, I'm not sure exactly what you'll need to know to help, so I'll just tell you what I think is important....
Current situation:
- If I boot the phone normally it freezes at the SONY screen and goes no further.
- If I attempt to boot into recovery mode, it loads the CWM screen (logo in the middle with instructions at bottom), but no actual menu or options. After about 5 seconds, this screen disappears, the phone reboots and then gets stuck on the SONY screen.
- If I connect the phone to the computer in Flashmode Flashtool recognizes it as being connected, but regardless of what I do, after about 2mins the phone reboots, loses connection with the computer, and freezes on the SONY screen as before mentioned.
- If I connect the phone to the computer normally while stuck on the SONY screen, the PC recognizes it though doesn't allow me to do anything to it, and Flashtool says I need to install drivers (I have installed every driver that comes with Flashtool).
How I got here:
- I've rooted the phone
- I've flashed Z2_DooMLoRD_AdvStkKernel_FW-438-v05
- I've unlocked the bootloader (via Flashtool)
- I've installed [Rom][Unofficial]Slim Rom 4.4.4 based on CM11.0, ROM for the Sony Xperia Z2
The phone was okay up until this point, however I wasn't happy with the ROM so I tried to reboot into recovery mode to wipe and install Carbon. This is when the trouble began.
Now it seems I can't do anything :/
Please help. This phone is literally 3 days and it looks like I've completely screwed it >.<
Thanks!

- If I connect the phone to the computer normally while stuck on the SONY screen, the PC recognizes it though doesn't allow me to do anything to it, and Flashtool says I need to install drivers (I have installed every driver that comes with Flashtool).
How I got here:
- I've rooted the phone
- I've flashed Z2_DooMLoRD_AdvStkKernel_FW-438-v05
- I've unlocked the bootloader (via Flashtool)
- I've installed [Rom][Unofficial]Slim Rom 4.4.4 based on CM11.0, ROM for the Sony Xperia Z2
The phone was okay up until this point, however I wasn't happy with the ROM so I tried to reboot into recovery mode to wipe and install Carbon. This is when the trouble began.
Now it seems I can't do anything :/
Please help. This phone is literally 3 days and it looks like I've completely screwed it >.<
Thanks!

I'm very pleased to say that this worked. Thanks!
Now, I think I might just persevere with the stock ROM for now and enjoy my new phone.
Thanks again to everyone who helped.

[Q] [HELP] Have I hard-bricked my brand new Xperia Z2?

Okay, I'm not sure exactly what you'll need to know to help, so I'll just tell you what I think is important....
Current situation:
- If I boot the phone normally it freezes at the SONY screen and goes no further.
- If I attempt to boot into recovery mode, it loads the CWM screen (logo in the middle with instructions at bottom), but no actual menu or options. After about 5 seconds, this screen disappears, the phone reboots and then gets stuck on the SONY screen.

How to recover your device from almost any kind of brick
Requirements
Check the pinned sites
Flashtool
FTF of choice for your device
2 Rubber bands (I am serious but only if your device has no response)
Step1
unplug your device from anything
open flashtool on your pc
plug your cable into your PC
do not plug the cable into your device
Step2
Hold your power button and your volume up button at the same time
your device should buzz 3 times
(this should take a few secconds)
if it does not take a few seconds then you need to put a rubber band around your device holding your power button and your volume up button, DO NOT LEAVE MORE THAN IT NEEDS TO BE LEFT, wait patiently for your device to buzz 3 times
Step 3
once your device has buzzed 3 times you are free to flash a FTF as your device is powered off
step4
if you dont know how to flash a FTF but have gotten as far as installing flashtool,Z2 drivers and downloading a FTF FOR YOUR DEVICE... then folow this step
within your flashtool window click on the lightning icon at the top left
select flashmode
navigate to where you downloaded your FTF (OR put your FTF in your /flashtool/firmwares folder)
select your FTF
Flashtool should give you a prompt to plug in your device
hold volume down and plug in your device
step5
wait for it to finish flashing
step6
your device is now recovered, enjoy...

You didn't unlock your bootloader?
Isn't Carbon ROM AOSP?
If it is, it needs an unlocked bootloader or it will get bricked

Okay I used to get into this kind of situation when I used HTC One, and what I did is try to flash recovery and unlocked bootloader again "using command".
And problem has solved. I think it is pretty much same for Xperia Z2, (ftf flashing method is not useful in this situation.)
I hope you know how to flash custom recovery using command. If not I think there is some thread that explains how to flash recovery and unlock the bootloader using command, if you can't find it plz let me know. Hope you have recovered phone next time I check this thread. Good luck mate :good:

Yeah... I know... A newbie mistake...
I Just follow the instruction available in the site. And there is just "root and recovery"
No bootloader mentioned
But u r right... Thats the reason

@Envious_Data: Bro, thank you so much for that. I my z2 have only 1 day, and i god damn it bricket, that even screen wasn't working. So for other people who had bad luck: first I rooted using Community Rootkit, then unlocked bootloader, and at the end I flashed via fastboot boot.img which one i extracted from zip file from this thread - http://forum.xda-developers.com/showthread.php?t=2702001. Command prompt showed that it works. I rebooted phone sony logo showed up, but then disappeared, and then was crying and sorrow. Three years of rooting,flashing without any problem, and now that. Thank you one more time, that's a great lesson
I do have some advice for people
1. Try to find help threads for your device, i have one for Z2 that gives some useful info, ill be adding more soon
2. Once you have got the jist of flashing then try to expand on that, i do recomend roms first because its harder to brick from a rom than a kernel or a non stock based rom such as CM11 or AOSP
3. Always keep a stock flashable rom (kernel too if you have a unlocked bootloader) on your device

A hard brick is by definition not recoverable by the user, requiring either special equipment ie jtag or RMA to fix.
I am quite surprised, and intrigued, at people flashing cm or AOSP on a two day old phone, was Sony experience that awful? You'd maybe be better served with a nexus device.

True friend, but I had an Xperia MT11i (Neo V) and all (fastboot, flashtool, CM, etc) was always no problem.
I've taken today for service (with CM11 (and cm kernel)) and see what happens ...
@Unbalanced I don't think your Z2 Hardbricked, if it were not ignite. Luck
Hi all, if it helps I did the same thing last night. Flashed CM11 without a recovery and wanted to revert back to my nandroid backup. I flashed doomloards kernal via fastboot. CWM started with no menu and just bootlooped. I then thought it may be a CWM issue, maybe no file structure or something. I flashed XZDuelKernal via fastboot and booted into CWM again and experienced the same issue. As this is a duel recovery, I then booted into TWRP. Recovery started and I was able to flash another zip then recover my nandroid backup. If you get this menu issue with CWM,try and flash a TWRP recovery and boot into that.
Also, as mentioned before, this is not a hard brick. It's just incompatible software and is easily fixed if you know what you are doing and prepared (nandroid backup, knowledge about fastboot and flashmode, ftf, recovery, unlocked bootloader).

Hi.
I believe (although I'm not sure) that I have bricked my Xperia Z2 in some way. When I press the 'power' button, the phone vibrates once and does nothing. I have tried to hold the 'power on' and 'volume up' buttons for a long time (half an hour with rubber bands), and nothing happens (as explained earlier in the thread).
I believe I am able to access the fastboot though, through 'Terminal' app on OSX. From there I can " ./fastboot devices " and get confirmation that they have loaded. I am also able to perform other tasks from here, such as flashing a recovery and " fastboot erase system -w " (which I believe may have got me to where I am now). I've been following things on this thread: http://forum.xda-developers.com/showthread.php?t=2277112
I have no experience in rooting or flashing, but attempted to flash a custom ROM because there were step by step instructions.
Anyway, I firstly used Sony's rooting procedure whereby an unlock code is generated etc. Eventually I gained access to the Recovery mode (via clockwork), and wiped the phone, installed the ROMAur zip and GApps zip. However, when I booted, it kept giving me warnings saying the apps were crashing. I've since gotten lost completely and need someone to help bail me out.
I'm hoping I can sort things out via the fastboot.
Thanks in advance for your help.

Download ftf file for your device and flash via flashtool.

Thanks for the quick reply Mario. I did just that (using Kuwait FFT for the D6503), and everything appears to be back to normal. Unfortunately I still have not got root access and can't remove the bloatware. As for the bricking issue however, it's solved. Thanks.
