Bootloop, no CWM, no Flashtool = Z Lost ?

Hello dear Community,
the prehistory ... about 2 weeks ago I get rid of my S2 and switched to the Xperia Z and I`am completely satisfied.
Because of my pre-"experience" with the S2, various Customrom's, Root and CMW I chose this day for these steps in the Xperia Z .
Got this in the course of the day and I Rooted the Phone and installed the latest CWM Recovery (bootloader locked). So far everything is working fine right after installation, I done a backup of my current StockFirmeware, if something goes wrong to have a backup ready.
After the Backup I Flashed this ROM
[ROM] [XZ] [07/03] Xperia KA02.2 Z Revolution ™ |
... via CWM, before the installation of course I wiped the Z, that nothing can go wrong ... I thought (backup?) ... The installation went smoothly, rebooted from the recovery and all i got was a .... Bootloop.
And here I am hanging tight since noon today.
Phone starts ... xperia logo appears, restart ... xperia logo appears, restart etc, etc. I thought I might still'm coming back into CWM, but None, no green LED on boot, if this is so, one should press on to the Volume + button to get into CWM ... doing nothing but looping again and again.
So i waited all day long until the battery was empty. After that i connected the Phone for hour to the charger. After an hour of loading time i tried to turn the phone back on ... But still no green LED .... Bootloop continue.
So i let the battery empty iself again. This time I connected the Phone via USB without switching on. Started the Sony Flashtool pressed the Volume- key and the Xperia connected to the Software, but due the Locked Bootloader i can´t to nothing.
That´s what i have been tried to bring this thing back to Life ...
Hope that anybody can help me get rid of this Silly situation
and BTW: SORRY FOR MY BAD ENGLISH !!!

You can try Sony Update Service.

Thank´s for your fast reply,
git my Problem solved
Wrong version of Flashtool was installed, so i downloadet the beta2 out of the Forum and now .... my Phone is back Alife

For those who have the same issue, try too re-flash the firmware following the procedure below :
1/ Follow the procedure for flashtool
Tick erase data if it still does not work
2/ Wait for flashtool to tell you to conned your Xperia Z
When it does get ready to connect it (step 3)
3/ Wait for you bootloop cycle end
--> Wait for the screen to turn black
--> Once it's black press and hold volume down

And i flashed kernel and rom after that
Thank u very much

[Q] Xperia TX boot loop after system restart

Hi!
I have been using Xperia TX for a few months, and I have experienced freezing problems for about 4~5 times, this all happens while I was updating apps in the Play store.
The phone gets a bit laggy as soon as it started updating apps, and it freezes soon. I am not sure if it is considered "freeze", since the download/installing progress bar is progressing, however I was not able to give any input at this time, so after one minute, the screen turn off as the screensaver is set to one minute.
I can't do anything else since it is not accepting inputs, so I removed the battery and inserted it back, and power on the phone, then I will get a triangle with a screwdriver icon, just wait for about 15 seconds and it will get pass there and boots normally. Sometimes I don't even have to pull off the battery, the phone restarts automatically.
Above were my past experience, however my TX freezes while updating apps in the Play store again today, and it restarted automatically. It boots past both SONY and Xperia logo, but got stuck in the "flow" animation, and restarted itself, doing this over and over again, it seems that it have got into a boot loop.
Note that I am using stock Android 4.0.4 firmware, I can't remember the exact firmware version now.
Is there any troubleshooting I can do before trying to hard reset the phone?
Also I would like to know if someone have the same experience (system freezing while updating apps, and does not accept any inputs, requires a reboot) with me before?
Thanks!

even if you get out of the bootloop, there no guarantee that the issue of freezing will be gone.
i suggest you repair using pc companion and then upgrade to the latest JB rom.
Else download the latest JB .ftf and flash it using flashtool.

Thanks for your feedback!
Just flashed the phone with Sony Update Service, and it is working fine now.

[Q] GT-N7100 multiple issues

Hi guys, first of all this is my first post here and won't be my last.
I am an Apple/iPhone long time user and want to tryout Android, just because I think it's time for a change , without knowing if I could get used to the new OS and wanting to spend as less as possible on this "endeavor" I bought a second hand Galaxy Note 2 GT-N7100 from a friend, the phone worked perfectly when I bought it, it had Android 4.1.2 on it and I wanted to update it to 4.4.2, did some research on the net about this (learned about the locked bootloader - this wasn't an issue for me coming from the iPhone) and updated the phone using Kies - and this is were the fun begins.
The update failed, and the phone was softbricked but could still go into download and recovery mode, after reading a few hours on the internet, I used Odin to flash a 4.3 stock rom for the n7100 which I downloaded from samsung-updates, the software got installed on the phone but it was very laggy (with the phone opened but locked, when I pressed the power button it took about 7-8 seconds for the display to light-up, the animations were very sluggish and phone was unusable).
I installed another ROM, using Odin, this time a 4.4.2, with the same results (every time I reset to factory setting and wipe cache from recovery - this didn't help).
I then installed clockwork recovery and rooted the phone then installed cyanogenmod 10.1 which worked almost ok but if i locked the phone after a few seconds the phone would restart, wipe cache/restore factory settings didn't help, i installed it again hoping it would be just an issue with the installation but had the same result, phone would restart.
I've followed all tutorials I could find related to this phone and this issue, installed several patches, reinstalled several stock roms, installed Criskelo rom, all with the same result, the phone is very very very slow and freezez after a while or it restarts after i lock the phone.
So, let me just give u some history on the phone, enumerate the symptoms and where I am right now:
History:
The phone was bought from Vodafone Romania, was never rooted and was never updated (before me ) and still has 3 months warranty.
Symptoms:
- Phone is very slow, unusable
- Freezes after the display is locked
- it is not recognized in windows, when I connect it i can hear the windows connect chime but the phone storage is not mounted, in device manager the phone is recognised as "cdc communication interface" which is not installed - i have the samsung drivers installed, and i have tried on other PC's with the same result, I also tried with several data cables - same thing - the phone works ok when in recovery/download mode
- sometimes when the phone is connected to the PC and the screen goes dark a gray battery appears with a "wait circle" and the phone freezes
- in recovery the phone displays 14 bynaries downloaded and also knox warranty void 1
- most of the roms freez in the language selection screen - i boot-up the phone (after i do a restore factory settings) the installing application dialog appears and then the language selection screen appears, then after 5-6 seconds the phone freezes - the freeze is not triggered by something I do it's triggered by time, after 5-6 seconds no matter what I do with the phone the phone freezes, if it makes any difference, exactly before the phone freezes the display brightness goes to the maximum setting.
Where I am right now
- I installed another stock rom, 4.4.2, it worked acceptable for a few minutes (it got passed the initial setup with no issues) then i left it on the desk, the display went dark and the battery thing happened again and the phone froze, i restarted the phone in recovery, did a factory reset, when the phone started it froze on the language selection screen.
I am at this for about a week now and I have no more ideas and no more patience, and run out of threads and tutorials to read, I am 1 step away of using the phone as a paperweight so please help, any idea would be appreciated, even if it's to enlighten me about what happened and telling me that the phone is bricked.
I am willing to try anything even if it is risky and can totally brick the phone, this is not my main phone and it's purpose is to help me understand android, and help me not make the same mistakes next time.
But, if it's possible I would like to fix the phone because even though it's pretty old it's still an ok phone.

Sorry wrong forum. You need N7100, not the n7000. Good luck.

[Q] Auto recovery not working/soft brick/bootloop- Tried flashtool/ SUS/

Long story short my sister upgraded to iphone so she left her xperia SP untouched for two days, which somehow drained all the battery ( i know it because LED blinked three times when I pressed power button). So I left it to charge for 3 hours using a wall charger & then following happened:
1. Sony logo came up.
2. Sony Auto repair mode activated. (Phone was perfectly working earlier).
3. Then the Sony rainbow wave kept on coming for hours.
4. A message popped up ‘Process system is not responding’ with option ‘wait’ & ‘continue’. I chose continue.
5. Phone was stuck on that screen for half an hour. Then I decided to switch off the pone normally. Power off popup screen came and screen froze on it for hours.
6. Then the process restarted and it has been the same way no matter what i try.
Solutions that I’ve already tried:
1. Repairing using Sony PC companion. Progress stay stuck at same point on all three of my PCs and then errors shows up. ( tried on windows 8.2/xp sp3/Windows 7 64bit).
2. Repairing using Flashtool. Everything gets loaded successfully but no progress has ever taken place. Even left it for a day but my phone’s battery died yet not flashed. Tried it on windows 7 and XP-SP3, with three different ‘*.ftf’. windows 8.1 is still pending.
3. I installed EMMA. It detects my device pretty well but as it is not rooted nothing further happens.
Installed all drivers prescribed in flashtool successfully. Reinstalled them after reinstalling flashtool and PC companion.
Tried rooting only kernel but didn’t work. It stayed stuck as well.
4. Updated java.
5. Took phone apart and pulled the battery ribbon out and repeated step 1-4. Still no success.
Any type of suggestions/help is really appreciated.

Okay, i am thinking you have troubles with drivers. Open up flashtool folder and go into USB drivers . Install it and see if your device detects it. Do not install drivers from by running flashtool.
By the way are you using the latest flashtool with latest drivers provided in its folder ?
I suggest you install a custom recovery (which you can get from a kernel even from flashtool by going into fastboot mode) and try to clear cache/ complete wipes. See if that helps. Make sure the recovery is specific to your android version. Do not flash a kernel which is based on 4.2 but you have 4.3 flashed etc.
Quote me back if you expect a reply.
Good Luck

XZ in continious bootloop, no matter what i flash/do

Hi guys,
Device info:
Model C6603, Unlocked bootloader
So i have the following problem, my device is in a bootloop and i can't figure out what the exact issue is. I'm out of options at least.
First a little background on how it came to be: (scroll down for short overview)
Before official lolipop came out I've been on CM12.1 for a few months, cm-12-20141221-INFECTED-yuga to be exact. When official lolipop came out I installed C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB following the instructions, although i see the thread has been modified (name, updated etc.) the instructions are the same. I did not install Xposed yet, because i wanted to try stock+root first.
After a few weeks of normal use, i used google maps navigation. This worked fine but when i arrived at my destination and picked up my phone closed google maps app but then my phone crashed. It rebooted to the point where i had to enter my pincode, but every time i was entering my pin it crashed and after a few tries it dind't even got to the lock screen but only showed the sony logo and rebooted(bootloop). I noticed my device was getting hot and left it alone for a few minutes, after that i started my phone again and was able to use my phone again. Until I started google maps again for the way back and enabled gps it crashed again, the same thing happened the phone would reboot when entering my pin, the phone wasn't hot this time. I left the phone alone till i got home, put it on the charger and the next day my phone worked fine again.
A few days later i was outside in the sun whatsapping, when the same happened my phone crashed and rebooted when entering the pin or slightly after. The phone was feeling hot, also because it was exposed to the sun for a while, in TWRP recovery it showed temperatures around 70 degrees celsius (i don't know if this is too hot?). After i had left the device alone for a while and try to boot it up it got stuck in a bootloop (sony logo), after a night of charging it got to the point of entering the pin code again but crashed and got stuck in a bootloop again (sony logo). And since then i'm not able to get rid of this bootloop. However i could still get into recovery (TWRP).
First i tried to reinstall the rom, factory reset and flash via recovery: C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB
This worked, and the device booted up but after a while it crashed and got stuck in a bootloop again (sony logo).
So all summed up:
cm-12-20141221-INFECTED-yuga
>> C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB
>> Google maps navigation >> overheated >> bootloop (sony logo) >> charging night >> working >> whatsapping in bright sun >> overheating >> continuous bootloop (sony logo)
What i have tried:
- Tried booting without sim card, withoud sd but doesn't work
- Flash same rom via recovery C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB : Worked once, but then crashed and went back in bootloop, now when i flash this only Bootloop (sony logo)
- Flash updated version of http://forum.xda-developers.com/xperia-z/help/lollipop-5-0-2-10-6-0-454-pre-rooted-t3116205 via recovery : Bootloop (sony logo)
- Flash kernel via fastboot http://forum.xda-developers.com/xperia-z/development/kernel-unlocked-bootloaders-t3114234 : Only recovery works
- Flash stock kernel via fastboot: boot (sony logo) one time then turns off
- Flash stock lolipop (with and without bootloader unlocked) via latest Flashtool : Bootloop (sony logo)
- Flash stock lolipop via xperifirm (C6603_10.6.A.0.454_KPN Mobile NL) xperia (with and without bootloader unlocked) via latest Flashtool : Bootloop (sony logo)
- Flash stock kitkat (with and without bootloader unlocked) via Flashtool: Bootloop (sony logo)
- Relock bootloader and Sony PC companion restore latest firmware : Bootloop (sony logo)
- Restoring serveral backups from TRWP and Phillz touch but they all result in the same bootloop, while at the time the backups were made there were no problems.
I'm pretty much out of options and begin to thinking something was damaged when the device overheated or a bad partion of a kernel is still stuck in the devices kernel.
Does anyone had the same issue, if so how to fix it? Or another option i could try, maybe someone spotted anything i did wrong?
Current state:
Locked bootloader, stock lolipop 10.6.A.0.454 flashed via Sony PC Companion recovery
Boots into setup, after a few reboots I completed the setup. But still randomly reboots when trying to use some apps or in general leaving it in standby for a while (might be due instability).
Thanks in advantage,
Jonathan

So the only things that you do that do not result in a bootloop are flashing a kernel. Try flashing a Stock kernel with Flashtool --> open flashtool >choose the flash button at the top left > flashmode > choose the firmware > check cache and data above and below check Only Kernel. Post result here...
Good luck

Don't do this. It will wipe your data and flash everything but the kernel, therefore losing root etc.
If you want to flash a stock kernel, you must leave everything in the "Wipe" section unchecked, and check everything but "Kernel" in the "Exclude" section.
I don't think this will help anyway, being that you're already on a stock firmware flashed via Flashtool.

Thanks for your fast reply, I think you meant: check everything but leave kernel unchecked (as kingvortex replied at the time of writing)? Since it is an 'Exclude' list. I flashed stock kernel, it shows the Sony logo and then shuts down. I used stock lolipop kernel from 'C6603_10.6.A.0.454_KPN' Mobile NL, and i also tried 'C6603_10.6.A.0.454_Customized CE1'. both have the same result.
I've got the most "life" after i restored my phone with pc companion to 10.6.A.0.454. Then, after being charged via the wall charger for a while, it boots up normally and goes into setup, since it is a complete restore. But crashed around the setup screen for wifi. The other options i tried do not come any further than showing the Sony logo, this stock one shows Sony logo >> android logo >> boot animation + sound.

I'm thinking it might be a case of a dead battery or battery controller of some sort. Because the phone only boots up normally, with stock android .454, when the phone is connected to the wall charger. Whenever i pull out the cable the phone crashes and reboots, also when not connected to the charger it gets stuck in a bootloop. However when the phone is connected to a charger and working for a while it still randomly crashes when using the device, sometimes these moments are suspicious because it sometimes reboots when enabling gps, wifi, mobile data or when starting an app, phone call or synchronizing accounts for instance. On a side note sometimes the battery percentage drops about 6-9 percent when rebooted one time or when crashed, also when i connect my phone to the charger the status led is red but when done showing the sony logo and when charging it turns green (or yellow, depends on battery percentage). This is why i think something internal is not working properly whether it is the battery or the battery controller, i don't know.
I still find it weird that the phone was in perfect condition before flashing .454 stock lolipop, it might be due to overheating that some components where damaged. At least i'm guessing this is the case because i know no other reason why it would show such behavior. Is there someone who has experienced something like this or another solution i might try?

In the mean time i bought a Z3, my XZ is definitely dead now after the battery has discharged and i can't charge it because it's constantly rebooting. However flashmode and fastboot are still working. Thanks for the replies. I might repair my XZ if i can get my hands on a cheap (broken) second hand and replace the internals, but i'll see.

Hi, i have the same problem... i cant charge and the constantly rebooting... and in my case also... when i try to flash any ROM, flashtool and Fastboot are stuck for 1 hour when try to flash system.sin (system.img)
i stop flashing after 1 hour... not sure if could finish after 2 hours :/
Cant use PC Companion because dont have charge in the phone (locked bootloader)
Any suggestion?
