after switching off, it turned to automatically shut down at sony logo

Hi guys,
I am in trouble.
My only phone is C6502 and I flashed it with 5.1.1 taiwan rooted rom yesterday.
My procedure was:
1, use flashtool to make it as rom 4.4.2 230 and rooted
2, use cwm to flash it with 5.1.1 rooted taiwan rom
at the beginning, everything went well. however, after updated several apps in google store, it automatically shut down for several time. I opened sim card back and used a stick to power off. after restarting, it stuck at the SONY logo and automatically and repeatedly restart. I have to power off with a stick for the second time. Since this second, trouble came. No matter what I did, it just automatically shut down at the SONY logo. I tried to flash it back to several roms and nothing changed. (no green light while flashing). Still stuck and shut down at the sony logo (different roms ha
ve different styles of logo, so it shut down at different sony logos). Charging doesn't work. it showed the red led first following with a green blink, and then no more light. The flashtool cannot recognize it as ADB mode but as flashmode.
Could you please help me. I hope you guys could let me know what was going on and how can I unbrick it.
Thank you for your time in advance. Wish you the best.

It's common ZL behaviour on broken battery controller (attached to battery). Reflashing will not help (it's hardware bug) but changing the battery (and it's faulty controller) definitely bring your Xperia back to life. I did it twice on mine (1st time it was not charging at all, stuck on Sony logo on boot, 2nd time it worked only with power cord connected).
After changing battery, just reflash it via official Sony PC Companion (if your bootloader still locked), then do whatever you want )
p.s. If you don't want wait / can't find new battery, you also can try short-pin method with current one. Idea is to bypass it's controller, so it will charge / work again. Search XDA to find out which pins need to be connected.

LG Optimus G (isn't even happy to WakeUp)(No LG Logo)

Hello to everyone, as I m new here so I dnt know whether I m putting it in right forum or not, but really In trouble and looking for help as 2 weeks ago I was trying to install official KDZ (before that I installed 5.1, which was working perfect rather than 1-2 issue so that's why I decided to get KitKat again) through Download mode, while it was on 90%, my LG F180K shut down and never restarted again ( after auto shut down, not started again) now what I got is just Notification LED working ( when I plug it to Charging or Laptop) otherwise nothing, No LG Logo Nothing else :crying::crying::crying: Anyone have an idea, so plz ?
Try press at the same time volume up and down then connect usb to your laptop. That brings your phone to Download mode.

Need help phone is not booting up.

Hello guys. I was using bootleggers rom for about a month, today the phone was lagging a bit so I just restarted the phone. and it went into bootloop and after a few minutes the twrp booted up.
I tried wiping the catch and davlik and I tried dirty flash the rom which didn't help, so I decided to do a clean flash to another rom (Carbon Rom) , and now the phone is stuck on ZUK logo .
What can I do to fix it?
Thank's.

My g3 bootloop

Hello everyone
My G3 (d855) (fulmics 8.0 ) started restating yesterday. when I turn it on, it restarts on lg logo before android come up and it stucks in a loop.
At first i thought it's a software issue and I did a factory reset usinng TWRP but still the same issue.
I reprogramed the same rom and then I programmed Official rom and still the same.
Today I found sth out. sometimes phone starts normally or after just one bootloop when the charger is pluged. so i think the battery may have problem.
I tried using a power supply to turn the phone without battery but it stuck again in bootloop. (phone draws 1.1A max)
any idea ?

Lenovo VIBE K5 Plus A6020a46 is not booting

I've never installed any rom or anything like that and i don't know much about theese kind of stuffs.
Yesterday it was working fine and then play store services or something kept craching so i decided to reboot my phone. It got stuck on lenovo logo i tried couple times it didn't boot. So i decided to factory reset it by using the thing that comes when i hold power button and volume button at the same time. When that screen came there was a lot of errors. Factory reset is not working or something like that it's just showing the same errors.
I hope there is a solution for it. Thanks.
Just realized i'm visible at the picture. Hi.
Any help?
