My tablet suddenly stoped booting properly. - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Hi, suddenly my tablet doesn´t boot. Everything seemed to be fine last time I used it (tuesday), then today I turn it on and got stock in Sony´s logo, reseted (vol up + power) and after sony´s logo just a black screen showed up and a blinking red light. Turn it off, I tried to charged it but when I plugged in the same thing happened when the charging battery logo should have appeared. I went to recovery mode everything seemed fine (I could even copy some files to external sd). I connected it to the computer fastboot is working fine; I clean flash it with flashtool to 32.4.A.0.160 everything went fine, turned it on but still the same problem. Fastboot is working fine, I even reinstalled TWRP and I have access to the recovery. My tablet was running 32.4.A.0.160, kernel by Nimadroid, Super SU, TWRP recovery. I don´t remember having done something risky (flashing something, didn´t turn on myXperia), the only thing I did before was intalling WhatsApp, but I turned the tablet off twice and used it two different days before this happend. Any help is appreciated. Thanks.

Galaxy Tab 10.1 Wifi P7510 stuck on battery screen

Hi
I used the factory reset function on my tab a couple days ago to delete all apps and such and upon reboot it was stuck at the slowly flashing Samsung logo and would proceed no further. I left it for a good hour and a half in that state before I tried hard resetting it but no dice. I've had it do this before when I first rooted it, but unlike that time it doesn't replay the whole boot animation, just the logo part at the end of the animation. I managed to get it in clockwork mod or bootloader whatever that function is and cleared all the caches and did a reboot recovery (i believe thats what it was called) but upon reboot it did the same exact thing. So after that I gave up and went to bed, but the next day when I went back at it again it wouldn't even turn on. After messing around with the power button and volume button trying to get into recovery mode it finally turned on but went to the battery screen with no other actions. I've tried several times to get it into recovery mode but it either wont turn on or it just goes to the battery screen. I have it plugged into my pc at the moment and apparently it is in recovery mode or something because Odin recognizes it. Says [0:COM3] and the box is yellow, but the screen never turns on though when holding the power button and volume button while it's plugged into a pc, the pc recognizes something plugged into the USB slot. My pc is only recognizing it as a modem and will do nothing else with it.
I have the Starburst rom and the overclocked kernel installed and would like to either revert it to stock rom or perhaps the AOKP rom, milestone 6. Is there any way to do this if I can't boot it into a state where I can access the SD card on my pc? All the guides I've found always require I put files on the sd card to flash in clockwork recovery mod. Thanks for any assistance
Edit: Solved it myself, feel free to delete this post. Thanks!

[Q] Nexus 7 Stuck in Weird Bootloop

My Rooted Nexus 7 was working perfectly. Now I am not sure If it is Soft Bricked or something else is wrong with it, It was charging one day and I took it off one micro usb charger and put it on another Nexus 7 charger. I went back and turned it on, Now it was stuck in bootloop, I have seen bootloops before, but not like this. It turns on and goes to the lock screen, then after a few second it freezes then restarts. I have been able to quickly log in boot into safe mode but it still freezes and restarts, I made it to the app menu once and then it sad , Unfortunately Launcher has stopped, I have cleared the cache and dalvik cache and nothing works, I have bootloader version 4.1.3 and CWM version 6.0.1.9, I have tried to format tablet and factory reset with cwm recovery but when I turn it back on I still see my stuff and I still reboots, I have tried to restore from a backup from a while ago with cwm but it fails. I tried to use nexus toolkit but I dont remember my version and I cant check, I gave it a guess but It can not find my device when plugged in, even in recovery mode, It said something about fastboot but i think i did that but I am not 100% sure what it is, I need to get this workig again fast.

[Q] Stuck in bootloop and recovery vanished

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.

My Xiaomi Mi9 no longer starts in Fastboot mode. (No OS Installed)

Good morning to alle? for now,
So now to my problem.
I had a lot of time yesterday and wanted to root my new Mi9 and install TWRP to adjust my device a bit. It all worked fine until the phone started into a boot loop and stopped working. Of course I booted into TWRP and reset the phone...without success. Then I deleted everything that was to delete and tried via. Fastboot Miui 11.0.5, which didn't really work. With Miui 10 it worked then and I could set up the device again. Then I thought to myself that it might now work to install Miui 11 via Fastboot (Of course it didn't). That was at 0:30 at night, so I was tired and went to bed. I switched off the mobile phone, the Fastboot mode, so that the symbol doesn't burn into the screen. This morning, about 20 minutes ago I wanted to start a new attempt, so I pressed the power button...and nothing! I also tried to press for about 20 seconds...but without success. I also charged the device for a short time, I noticed that the LED does not light up during charging. But I can't imagine that the device is empty, because yesterday it had 100% battery. Now it is hanging on the charger. I also tried to start the phone via Minimal ADB and Fastboot, didn't work, because no device was detected on the PC.
I hope that is still somehow to save, I was perhaps a little overconfident there. But I think I am in good hands here and a solution will be found.
