[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.

Your battery is dead... I had the same problem some weeks ago. I had to buy another battery and replace it. Theres a thread where someone explained how to solve through another way, i think changing some cables i dont remember.
But for now my suggestion is to buy another battery and replace it o send it to Sony.

With your problems is your battery seem dead , but you can try do :
- Let ZL died then connect the charger
- Start Flash again with xZL power off then press Volume Up try to Flash Manually with Flashtool
- If 2 steps above cant Made your Phone Normally , Just change the Battery NOW .

[Q] Xperia ZL keeps rebooting

I have the C6506 ZL and this morning i received the notification telling me I can update to 5.0. i download the update and when it finished installing my phone reboot itself and kept rebooting after the Xperia logo
I tried connecting it to my laptop but my computer doesn't recognize that anything is plugged in, anyone have a solution?

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.

Any tips to make it boot again - Sony Xperia M5 Dual

Hi,
I am looking for a piece of advice regarding a way to make my phone boot up again.....
Issue:
I have a Sony Xperia M5 Dual (E5633) that suddenly stuck and once force restarted it won't go beyond blue screen. Then I tried to factory reset using power/volume+- key combinations few times and it ended up not booting at all. After went to a technician they managed to boot it up by some method. They said they did it by heating it up. But again it suddenly stuck when I tried to open an app and went dead. (I have to wait long until I can go to this technician again)
Symptoms:
Only a red LED is lit when connected to PC or charging it up. Not detected at all by the PC/Xperia companion. No response to reset keys, power keys etc.
Any tips on:
Please do you have any tips to make it boot again for one more time so that I can backup my data and flash it so that the problem most likely will go away?
Any idea of the test points of this model? (So that at least I can flash it.
Thanks.
put in fozener 2 days and take out to power charger, it work for me
