[Q] Stuck in bootloop and recovery vanished - Xperia Z2 Q&A, Help & Troubleshooting

Ok, so something seems to have gone very wrong with flashing my phone :S
I managed to get recovery working yesterday, and followed the steps in this thread, http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155 , to create a pre-rooted 5.0.2 image. I put it on the external SD card, booted into recovery and installed the flashable zip, then used flashtool to flash with the instructions (though I also cleared Appslog, Cache and Data to get a fresh install). This went fine and everything appeared to be ok. I then tried to get the Xposed Alpha installed, but after that whenever the phone was rebooting it just hung if trying to boot to Android. I tried re-flashing with Flashtool, but still got the same issue. Would boot fine the first time, but then any restart it would just hang and crash out. Tried clearing the cache from recovery, but no difference.
So today, I went into recovery, re-installed the flashable.zip, then powered off the phone and flashed using flashtool, just as I had yesterday. Now though, my phone wont boot. It shows the Sony logo, then a blank screen, then restarts. Even worse, it will no longer boot into recovery. I hold the volume down button when the LED shows, nothing. I try holding the volume down button all the way through several bootloops, nothing.
I've tried to re-flash using flashtool which goes through the process ok, I can hold the volume down button and connect the cable once its in the process of rebooting, and it goes through all the process fine. It then powers off as expected and I can just disconnect and power on the phone. But it's still stuck in the bootloop and I don't have TWRP recovery.
Is there anything I can do to get my Z2 working?
Update - Re ran flashtool, this time not excluding system, only Partition. It now gets a little further, going to "Powered by Android" and giving the purple wavy lines, but after a minute or so it just hangs and restarts again. And still no recovery sadly....

I think I've got it sorted...
Used Flashboot again to do a flash, excluding System and Partition. This time the phone does boot up normally. The downside being that my root was gone. Despite my flashing a pre-rooted image, it seemed to just put a stock image on. And my recovery is still mysteriously gone.
In the end, just to get things completely back to a stable/stock starting point for later on, I ran a repair from PC Companion. Seems I was in the none rooted position anyway so figured I'd get myself to a more certain position. At least this way I can wait for someone to come up with a root for 5.0.2 so I can root and get recovery back.

[Q] Stuck in weird bootloop.

So I've been using Kang's ICS preview for about a week, and I really liked it, except from some bugs such as freezing after not using it for a few hours.
Today when I got back from school, (not used the tab for 7 hours) I tried to turn it on but I couldnt get past the loading screen, so I turned it off by holding the power button for a few secs.
Now I just cant get it to load up normaly, its just goes to the bootscreen, stucks, then its impossible to turn it off.
I tried going in to CWM and wipe data/cache but that freezes too.
Is there any other way to wipe it and install another rom like Overcome?
Mine did this as well. It would hit the Samsung loading screen and never go any further. I basically had to unroot it and take it back to stock via ODIN. Hopefully this works for you.
Hit up this link and download the big blue link at the top labeled DOWNLOAD:
http://forum.xda-developers.com/showthread.php?t=1474971&highlight=odin
Follow the directions to get into the Download Mode, then jump down the unrooting part.
After its done with the download it will reboot automatically. Soon as it does this make the tablet go into Recovery Mode. It should go through a script and reboot automaticly. Again don't let it boot normally, make it go into Recovery Mode. I think it took a few times for me and then it eventually went into Recovery. I then did a factory reset and rebooted. Now I have an unrooted Samsung firmware. Back to scratch though, but fine with me! I was getting worried I wouldn't be able to get it back.
Oh...and this process will wipe your internal memory as well.

Went From ICS to Gingerbread--Stuck in Boot Loop. Please Help.

I went from Shostock2 ICS to Shostock Gingerbread--flashed through recovery, everything seemed fine, rebooted a couple of hours later and the phone froze at the "Samsung Galaxy S II" screen. As of now I have NOT been able to get back into recovery though the volume rocker/power method ... Nothing happens at all. Half the time my phone wont boot, period, but if I pull the battery and put it back it will boot the first time into that same screen. Not at home so I can't connect it to my computer but if I can't boot into recovery not sure how I'm going to get my PC to recognize the phone .... (sigh.)
Please advise.
EDIT: Finally managed to get into recovery via volume rocker ... Don't know why it worked this time after failing over and over before. Have reflashed the Gingerbread zip ... Keeping my fingers crossed that it works out.

Boot into recovery and wipe data/factory reset, that should get it to boot after you flash the GB zip!

Lenovo A820 won't start

Hello everyone!
I have a Lenovo a820 with Lambda rom 2.4v.
I'm using it for a couple of weeks now with this last version, and everything was fine, until suddenly it froze for a while, I unplugged the battery and plugged it again, and what I notice was that the phone restored itself to when after I installed the rom (meaning all of the apps were gone).
So I tried going into Google play, installing some apps back, and I get this error -24 telling me its unable to install the app, happened with any app I tried. so after trying a few suggestions from the internet about this error, I decided to format it and install the rom all over again.
I go back to recovery mode with CWM, try to install the lambda rom like I did before, and in the middle of the installation it reboots and gets stuck in the "lenovo" screen like when you boot it. so after waiting for a long time I unplugged and plugged the battery again, went through the procedure again this time it installed it 100% rebooted so it would boot with the mod, and again, it freezes at "lenovo" start screen unable to boot.
went on recovery mode, formatted system, data, emmc, everything... I think that's the issue here. but im not sure.
After that, tried to install again with the same problem.
The problem now is. it won't even start I press the on/off button to start it normally, and I dont even get the "lenovo" screen, I tried going into recovery mode and no luck.
It's like the phone is dead! Although I have another Lenovo A820 and I tried the battery, and its 60% so that's not the battery.
Do you guys know any tricks? or any tools that I could use to get my phone running again?
I would appreciate it very much, any help you can give.
Matt.

My SM-G357FZ is sick after failed root

Now since it's my ONLY phone, I beg you to help me as fast as possible!
I tried to root my phone through Odin. There were two files to load. I've loaded the step1.tar, but failed to load the second one.
After I loaded the first file, my phone rebooted into recovery mode. It was looking kinda different from the normal one. Like inverted colors or something. When I tried to reboot the system, it was plain black screen with errors ike "..... has stopped". I turned off the phone, and turned it again, only to see recovery mode again.
EVERYTIME I turn on my phone, it goes to recovery mode. When I choose the reboot system option, it goes black screen with errors. If I choose to wipe everything, and then reboot it, it goes absolutely fine. Untill I turn it off, of cource. Then it goes to recovery mode again.
HELP PLEASE

Well, it doesn't seems important error. Just download stock rom for your phone and reflash it, it will works again as you wish. The problem is you've flashed wrong file that it results a soft brick.
Edit: Not a soft brick, but a software failure.

Soft brick - stuck on Sony logo

Just gonna cut straight to the point.
Wiped my phone to flash a new ROM, selected 'Clean to install new ROM' but instead of then flashing a zip file, i went to Reboot Recovery.
I then hit No, thinking it would take me back to the main menu, but instead it continued to restart, and now it gets stuck on the Sony logo.
I've tried flashing completely stock ROMs and also this one which, those with similar issues has said worked for them, however nothing appears to be working for me.
It does seem to flash successfully, no error messages that i saw in Flashtool, but upon booting up it still get stuck at the Sony logo. Either just Sony (older ROMs) or Sony with Xperia at the bottom (newer ROMs), so i guess the ROM is installing fine, but there's something else that isn't?
The only way to shut down is holding down Power + Vol Up, and there is no LED light (green, purple, red) to notify of anything.
And because of this I no longer have recovery either, where I could just flash a new zipped ROM and be on my merry way.
Any suggestions?
EDIT:
Ok so I hate when this happens, where I figure it out a few mins after I'm made a post (after stuffing around for several hours already).
I've just tried flashing several different ROMs again to no avail, tried once more and checked the two boxes in the Wipe options, seemed to take A LOT longer to flash, but it's now working fine
flash any ftf or chech here
