Xperia Arc S, big problem

Well here it is, my Xperia Arc S originally had a problem where the display kept turning itself on so i did some reading and apparently it might have been some software, so i tried doing a factory reset and that didn't work. So i tried flashing it on Flashtool but then i realised i couldn't because everytime i turned my phone off it would turn itself back on so i couldn't put it in boot mode. And now i can't even get past the Sony Ericsson logo when i boot up so i think of anything to do now because i can't flash it and turn it on. Please can someone help me.
Side note i did drop my phone in water a few weeks ago and there were problems with it booting but i thought it was resolved because they disappeared.

Phone cannot turn on itself. Unless you have charging cable attached and it goes to charging mode.

UPDATE: I was able to flash 4.0.4 firmware onto the phone after repeatedly trying to get it into flash mode but the problem still remains, the display keeps turning on by itself and whenever i switch the phone off i hear a small vibration and it turns itself on (with no charger attached), i'm thinking there might be a problem with the power button but i'm not sure.

Does the button act any other way than normal?

You mean does it feel different? Like the clicking? It feels fine to me, plus when i'm using the phone the screen doesnt just turn off, its only when i put the phone to sleep it turns the display back on and then it turns off again and so on. It behaves as it should when i press it

I didnt drop it in water on purpose, i meant i dropped it and there were issues with it booting up, i left it in rice overnight and it was fine the next day

I now what you mean, I have same problem with mine. The screen flash like if it had unanswered phone calls its really anoying. My phone never had any accident until now as well. The gap betwen screen flashing can go from 30s up to a minute. Sometimes it stops and goes again. any sugestion?

Need help with my ion!! :'(

Hi i know there are threads on this and ive read countless ones. i installed BlackZax'7 [The Next Level Begin] on my LT28AT running LT28H LT28h_6.2.B.0.211. everything was working fine after first reboot. call texts 4g lte everything was perfect i was extremely satisfied. then restarted once all my apps were downloaded and went to put cwm recover on it and boom i got bootloop.
Naturally i headed to the forums here on XDA to follow the tutorial to recover from bricked state. what happened was i got bootloop and held Power and Volume + to reset to go to download mode, felt 3 vibrations which from my understanding was a hard reset. i followed the tutorial which said to leave it plugged in until solid red light turns green. well when i plug it in i get the solid red light however no green led. every once and a while ill see the sony logo and starts to bootloop. held volume down to try to get to download mode but refuses to do soo........
after a while bootloop stops and goes to solid red led.....and repeats the same process after a while.
what do i do ive searched forums and some have said to take the battery out however unfortunately i dont own the right tool to get the plating off after the cover.
what should i do its my only phone.......
Any help or a way to fic would be life saving

Same problem here
Hello,
I have recently stumbled upon the same problem and am completely clueless of what to do.....did you find a solution for this without disassembly?
I think what makes sense is to let the phone sit for a couple of days till the battery drains out and to put on the charger then for a couple of days......
please do reply.
Thanks.

Yea I fixed it. What You have to do is let it die then have flashtool ready connect to pc to charge use a rubber band or hair tie to hold the volume down button pressed (You have to have pressed before the Sony logo appears the first time or you have to start over) if it works then you will come back to a fixed phone.
*you have to flash before first bootloop*
I used a hair tie to keep the volume down button pressed had flashtool waiting for download mode plugged into the pc to charge then after about 1-2 hours I saw my phone boot up. It takes time and patience but the rubber band trick worked like a charm

How long does it take to tie?....i left it sitting for about 30 hours i dont think the battery died completely because i tried flashing the tft with flashtool tying a piece of string on the volume down key,but it was boot looping again!
how long should i leave it for the battery to die....it took only 10 minutes for the mobile to charge after the 30 hrs period and it started boot looping without entring flash mode.....i even tried to flash a kernel through fastboot....no use...boot looping!!
PLEASE HELP!!!

You need to read the forum with more attention: it is all written up...
Start your flashtool and pick stock rom. Let the program unzip the files. When you get pop up to connect the phone, connect your fully disharged phone and leave it alone. It will start flashing automatically in about 15 min.

Hello guys,
For the second time i got a stuck in a random bootloop the first time i was insured and got a new one now i got the same problem with this one and i'm not insured anymore. Everytime this happened I was at a party with liquer but i cant seem to find out if it's water damage or not I disambled the g3 and found nothing so i leaved the disambled parts in rice for a day but that did nothing.. When ik plug it into the pc it get's recognized en goes into download mode and the screen works well it also goes in recovery mode. When the phone is off and i plug in a charger ik get a battery icon with a loading circle but it get's stuck everytime and the led doesn't turn on. I tried flashing it but there seems to be a problem with the drivers and the programs so it fails everytime so ik don't know if this is hardware or software problem.. one time before i tried flashing a new rom it loaded till the updating applications screen. can somebody help me out before I bring it to a repair shop and they charge me bull**** i'm getting crazy cause it's the second time this happened and i did nothing crazy??
btw sorry for my very bad english

[H815] Phone keeps rebooting when charger not connected

Hi all, I got a serious issue, it's going to be a long post, because I want to provide as much detail as possible, so please read my whole thread!
My LG G4 H815 keeps rebooting whenever my charger isn't connected, effectively making it unusable.
When I unplug my charger, my phone could be OK for like a couple of minutes, but then the screen would suddenly go black, the LG boot logo appears and tries to boot back into my ROM.
Once i'm on the simcard code insertion screen, I would type my code as usual, but upon pressing the check mark, my phone emmidiately shuts off again and reboots again into an endless rebooting cycle like this:
Black screen -> LG Logo -> Custom ROM boot animation -> Simcard code insertion screen -> I press the check mark after typing my code -> REPEAT EVERYTHING.
(Sometimes I'm not even done typing my code and it would still reboot)
I don't have the official charger anymore that comes with the phone and I don't remember what happened to it and where it is (I think it was broken or something), so I've used a very different charger for quite some time now.
I've had bootloop issues before back when I was still on stock LG firmware, unrooted and covered by warranty, I've sent it back for a repair once but now it seems that i'm having a problem again.
My warranty period is long expired, so returning it now would be pointless.
However, maybe the problem could be the battery as well, meaning that it might not be a faulty motherboard after all, but I'm not sure.
I tried shutdowns for cooldowns, a cache wipe, pulling out the battery and putting it back in, charging to 100% while the phone is off but all without luck.
I've had this problem on CypherOS, LineageOS and on AICP (which are all the custom ROMs that I ever tried on my G4)
PLEASE. HELP. I can't take this anymore! I have to constantly use my phone plugged into a charger and it's become impossible to use it without it! :crying:
(EDIT): Nevermind, I solved it by getting a new battery 2 months ago.
