My Xperia ARC won't boot up

Hi guys.
I'am in truble. My Xperia ARC won't boot up. When i tying to turn it up, nothing happens, just blinks the green notification light.
What happened?
I rooted my phone (so the bootloader is also unlocked), everything was fine. The problem started, when android asked me to update the phone. I said: Why not? The phone turned off, and since that it won't boot up.
Please help.

Sounds like you have to flash a rom... Can you connect it to your pc with flashtool or fastboot?

[Q] Xperia ION - Hard Bricked - 2 times

Team/Member XDA
Please help me ( putting this line here shows my agony/desperation)
I have ION LT28H (Boot Unlocked/CWM 2.3 Installed) and yesterday I installed XZX Xperience 2 using cwm, it worked fine. later I installed some Fix and booted, it got FREEZE on xperia wallpaper. later by pressing SWITCH ON and VOLUME UP , it nudge 3 times and went in to deep coma (Hard Brick). I put it on wall charger, after 25 hours red LED came on and some time later fone booted and on SONY logo it shook 1 time and rebooted, it kept happening the led went GREEN.
at this point i was so excited and went in to cwm and clear/wipe factory setting and clear the kelvin cache and INSTALLED again XZX Experience _ ION (link given some where in xda), i booted fone .. it again FROZE on SONY logo .... I force restart it by pressing POWER+VOLUMEUP button for 5 seconds it nudge once and restarted and froze... I repeated the process and by opening my FLASHTOOL I call the Original JB ROM 4.1.2 for xperia ion TYT file. THE FONE was connected in FLASHMODE as flashtool was telling me.... then flashtool went in to " Preparing files for flashing Preparing files for flashing" status and immediately after flashtool said that fone is in MTP Mode ... and dialog box started coming saying that connect your fone in flashmode while pressing key......... (THE FONE WAS BLANK, no SONY LOGO and NO LED) `````` I read about the Rubber band trick and while my mobile is connected to PC, I tied the rubber band pressing VOLUME DOWN key to exhaust battery... It was suppose to take 9+ hrs... but after 2 hrs or so, the mobile RED LED started again and then SONY LOGO came and FROZE.... I HAVE PUT IT AGAIN to WALL CHARGER... ( thinking its still recovering from HARDBRICK mode) ....
Now as i was typing this post, SONY logo went of and the fone is showing RED LED and its on WALL CHARGER....
now
1. what will be my NEXT STEP ?
2. if fone was never recovered from HARD BRICK mode then why it started this morning to CWM ?
3. Have i forced it back again to loop whole by stupidly installing xperience_ION again
4. by putting rubber band and exhausting battery and RED LED coming back... has put the ION to HARD BRICK state again?
just love my roooted xperia! plz help me revive it....
~ if i give to to local sony dealers what exactly will they do and approximately how much the repair/reinstallation may cost me (USD $150- $200 ) ? -- but i don't wana do that they will put it back to Gingerbread again as ION never had offical mideast JB released, i flashed EUROPE ROM to ion few months ago...

Possible Flashing mistake
YasuHamed,
there are two modes for Experia ION, one of which is Fastboot.
Next time your experia switches on, try to install using the sony software update service which is quite different from the flashing tool you are using.
Check and let us know what happens. look online for instructions. SONY | make.believe

Your kernel is broken. You need to flash good kernel after (or before) installing XYZ.

[Q] Sony Xperia Ion LT28h Rebooting issue.

Hello there,
I have been using my xperia ion since around 6 months with stock rom and never tried to tinker with anything, lately suddenly my phone stopped working i.e it started a reboot loop. the phone turns on to the sony logo then gets to the 'rethink possible' screen and then a blue/black glaze appears and the phone restarts which happen again and again, as this phone is off warranty, i tried to flash it some other (4.1.2) stock rom but still no luck, when i connect my phone to the pc using the usb cable while holding the volume down button, the green led does shows up but the flash software says (error flashing - aborted). I have attached a picture of the same.
Please see into it and help me get through it.
I will be much thankful fellas.

i think you need to enable usb debugging

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.

Sony Xperia M C1904 won't turn on Red light blinks.

I flashed Cm13 in my XPERIA M c1904 CM13 was quite stable but it was not reading my SIM Card, I found on internet that maybe flashing with TWRP version 2.6.0 will fix the problem so I flashed the recovery in my phone and after I unplugged from the usb phone didn't start earlier I was getting vibration then it didn't start, I was able to go in flash mode I flashed some other recoveries even they didn't made any difference. I kept my phone for charging for a night in the morning now there is no vibration just red light blinks 3 times and nothing else...cant even get in flash mode or fastboot mode...to flash stock rom from flashtool. When I connect the phone with the usb no blue light comes or red and green light flashes just the red light ..... its annoying earlier also I tried flashing cyanogen mods and they caused me errors earlier cm12.1 didn't got any cellular signals and my imei gone blank... Please Reply fast!!! I really loved this cm13 if only the sim card problem was not there.....

I have the same problem here. I flashed the CM13's recovery img, booted into recovery but it wouldn't read the SD card, so I couldn't install the ROM. So I flashed another ROM's boot.img with TWRP and tryied to install ArchiDroid that I had installed in the past. After the installation it won't turn on, just the 3 red light blinks.
Can't connect to fastboot mode or flash mode.

I solved the problem now. In my case it was a dead battery.
I borrowed a charged battery from another xpm and the flash mode connection worked.
Then I flashed a stock firmware to restore my xpm back to normal.
After that I managed to charge the battery normally.
It seems that if you don't have an firmware installed, the battery won't charge.

blinking red thrice
Me too had same prob in unrooted xperia m.Went to sony service and they replaced charging port and did a software update...now ok...
