Xperia Arc Motherboard Problem - Xperia Arc Q&A, Help & Troubleshooting

Hi,
I applied the procedure in se website unlockbootloader. And now my phone is bricked. i tried every method in this forum to bring it back but nothing worked.
-Flash didnt work
-green light is blinking when plugged in, continuous green light when connected to PC
So i decided to send my arc to service. one week later they told me that phone is not in warrant because of unlock and somehow motherboard damaged. and they told me that they cant do anything. (not even changing motherboard or smt.)
what i am asking is, is that possible. i mean could motherboard really damage because of this? of even damaged cant it get fixed?
please guys help me.. i only used my phone for three weeks and i dont want to throw it away.. (

I can only think your incident as an co-incident rather than anything else. (i.e. you unlock the boot loader and something that was troubling earlier gave way at that point of time).
I'm not sure on the repair as I'm not that technical. Hope someone can help you with.

And is motherboard something changebale? is there anyone who knows how much is an xperia arc's motherboard..

Just had the same problem today..... after unlocking the bootloader my phone bricked... i then flashed it, and got it fixed. but then I accepted the OTA by mistake... so now it's dead... totally dead. the screen won't even come on. When i press the power button, the green light flashes, and when I press the power button when holding the menu button, it vibrates.... Any ideas?!?!

Well and truly bricked - desperate

Hi all,
I desperate need help. After an unsuccessful radio flash, my Desire won't even turn on. No response from any buttons or lights. Here's how it happened:
I'm relatively new to Android. I recently bought a Desire, to replace my Touch HD, which has seen about 25 different WM ROMs, over it's life.
I successfully rooted my Desire and had tried a few ROMs. I was sitting on the MoDaCo Custom ROM r17, which was all customised and running perfectly. I'd even used ADB to successfully update my wifi config to connect to my company LEAP-authenticated network.
I decided to flash the latest radio (32.37.00.32U_4.06.00.16_2), from this thread:
http://forum.xda-developers.com/showthread.php?t=687464
I entered Recovery using 'Fake-Flash';
I started flashing the radio image;
All the good messages were scrolling down the screen;
I kept one eye on the phone while I worked on my laptop;
I saw a message saying something to the effect of "Finished installing radio..." (sorry, I don't remember the exact wording);
The blue recovery menu had returned, with 'reboot device' as the default selection;
As I clicked the trackball, I saw another message appear under the 'finished' messages, which said "Writing rad " I guess it didn't have time to print the whole message, when I selected reboot.
The screen went blank then a graphic appeared in the middle (where the recovery exclamation mark and triangle usually appear), of a software box with a curved yellow arrow over it and the android icon peeking out from behind it. I left it for a while (already had that sinking feeling) then pressed the power button. It switched off and stayed there.
Since then, nothing that I've tried has received any response. Various combination's of button pushes, USB connection, removed SIM, SD and battery...nothing, not even an LED.
I've searched and haven't been able to find any solutions to this particular situation. Can anyone help, or am I totally bricked?
Regards, PF.
The radio update does 2 reboots to install it. The software box with yellow arrow is the default graphic used by the fake flash recovery as far as I know so that wasn't any real problem.
I know this might sound silly, but is the battery charged?

No question is silly under this circumstance!
Yes. I'd just taken it off overnight charge. 100%. If I plug the USB cable in now, there is no response from the LED.
Leave the charger plugged into it for about 5 minutes and see if there is any response to it. With the usb bricks it would take nearly 5 mins to register and the led to light up.
I know this isn't a usb brick, but I've not seen anyone with a failed radio flash that has caused the phone to totally die to the extent that it won't even switch on.
I take it you have tried the usual power and volume button combos etc?
I suppose if there is no quick fix for this, the fact that it's totally dead may go in your favour if you try to get it repaired/replaced under warranty

ok. The charger has been plugged in for 35 minutes and still no response.
Also don't want to sound patronizing, but have you taken the battery out and turned on with the back button helld?
Ignore me, just reread your original post.
the procedure u said sounds rite, thats whats ment to happen, when you flash a radio, only other thing that comes to mind is, sure the radio u flashed was for the gsm desire?
so what youre saying is that your phone simply doesnt turn on, not for a second?
if you press the power button NOTHING happens?
are you sure your charger isnt broken?
have you tried charging it through your pc?
have you seen if its recognised through adb devices on your computer?
have you tried a new battery?
if your phone is simply dead, it must be a hardware problem, in which case you can probably send it off for repair and not have your warranty void as the whole phone will need to be replaced. they cant identify if you have voided your warranty if your device doesnt turn on.

Right first time. It won't turn on at all. It doesn't react in any way to any of the button combinations I'm aware of from rooting and flashing it. Nothing happens at all.
I live in an HTC household, so I've tried a number of chargers and cables, including the PC's USB port. I haven't tried another battery...but the incumbent battery was holdng a good charge and was 100% at the time. What's more, I remember that the phone can run on the charger without the battery.
Not surprisingly, adb devices shows no connected devices.
I think everyone is right, it's back to HTC. I *hope* you're right that they cover it under warranty. I'm going on the weekend, so I'll let you all know the result.
Thanks to all for your help.
I think you can try to remove battery, leave the phone with no battery for 30 minutes and then try to insert battery and connect to usb without power it on to check if LED (and than the phone) is revived.
I had an Acer Liquid that gave me same problem, pratically when a flash on the radio go wrong, the device go in "protection mode". You must also check on the net if there is a protection mode on Desire too, and if there is a button combination to unlock it. I repeat: i just giving an idea becouse the same problem happened for me on an Acer Liquid, so i'm not sure if it's the same for the Desire.
Good Luck
Maybe a usb brick? No usb is no charging. So when you didn't had a full battery, it may be went wrong on that.
Try another battery, if you can get to one.

In the usb brick situation you can still charge. This isn't it!

Ok i didn't know that.
If the phone doesn't turn on at all, you can maybe try sending it back to the shop for replacement. Chances are, they won't be able to know what happened, so you can pretend it just stopped working.
If it gets back to HTC, they probably won't bother to figure out what's wrong with the phone and just give you a replacement. Otherwise, they'll just send you the phone back and you won't have lost much (maybe postage costs?).

Thanks for the suggestion. I left the battery out overnight. Then tried to activate it (all the usual button combos) with:
Battery out, USB cable plugged in;
Battery in, USB unplugged;
Battery in, USB in.
I scoured the 'net for anything on protection mode for the Desire...no luck. If there is one, it hasn't been posted yet.
I would just act stupid and try to return it under warranty!
I think it should be ok to RMA this, if its completely bricked there is no way of them knowing that you tried a different radio.

Yes, if it's totally bricked then just send it back to HTC and they will change it with no problems just same as acer done with my Liquid
All's well that ends well
Good news...
The HTC service centre were kind enough to replace my 'faulty' handset.
Re-flashed with r19 and radio updated (patiently) successfully.
Thanks all for your support.
Nice one. Glad it worked out for you

[Q] Bricked phone? Flashing red LED w/ no vibrations

Background: I was flashing a backup via TWRP, which failed because it could not write to memory. I rebooted the phone and it no longer responded.
Currently: the phone only has a blinking red LED whenever the USB cable is connected. I cannot connect into fastboot. The phone does not respond or do anything. No vibrations.
Is there any possible way to fix this? Or am I screwed?
Been there. No button combinations work nor vibrates at all. PC sees the device, but it is unrecognized. The LED flashes, but that's it. In the end it was power problems, battery and motherboard had lost communication with each other somehow. Thankfully the phone was under warranty and they swapped the mobo.

Thanks for the reply. You think they'll be able to find out (or be bothered to find out) that I unlocked the bootloader? Standard rooting = no warranty problems :\
I guess it depends on how much they want to find out. Although I believe it's pretty much impossible to find out anything if your mobo is dead unless they do some really complicated soldering, which I doubt they would.
Thanks for your help! We'll see how this goes once I get back from holidays. Also, what excuse did you give to justify the phone getting sent off?
Well my case was a little different: I bought the phone second-handed and the guy told me that nothing had ever been done to it (no rooting, no bootloader unlocking or whatsoever). However I found out that it had been and still was rooted, so I recycled it via Sony companion and charged it fully afterward. 5 minutes later it died. When I went to the service center, I didn't tell them much, nor did they ask much. "The phone went to sleep and never turned on again" had enough justification for them. Hope it's enough for you as well.
I had this issue when my phone got water damaged. I left it plugged in for a few hours and it would boot after, though the backlight was dead due to the aforementioned water damage. It might work for your phone.

Possible broken Power IC? Bricked phone? Assistance needed.

Hi everyone, I am looking to troubleshoot my T-Mobile Galaxy S4 which I believe has suffered from a Power IC malfunction. It has all the symptoms that relate to a broken power button, which of I already sent in for repair and that didn't seem to fix the problem. The guy installed a brand new power button and the problem still persists. Continued researching and it might be a broken Power IC chip.
The phone will power on for a second and display the Samsung logo, then shut off and reboot itself and sometimes be in a constant vibration cycle like it's trying to power on. Sometimes it just freezes on the Samsung logo and will not continue past that. Sometimes if I'm lucky, it will boot up like normal but once it gets to the T-Mobile splash screen, the screen will distort and then reboot itself where it will just go through either of the symptoms already mentioned. Weird thing is, I am still able to boot into recovery (takes a couple tries though) and download mode fine without any reboots or anything. I have tried flashing numerous stock firmwares/ROMs via download mode/recovery in hope maybe that'll correct something, but to no avail.
The problem happened shortly after I accidentally dropped my phone getting out of the car. The phone worked fine for a day and then one day while driving, the phone did something crazy and froze up, displayed the power menu, and then shut off by itself. Then after that is when all the problems happened. I took the phone apart and cleaned the power button. Rubbed the contacts with rubbing alcohol and even tried to get inside the power button with some. Took a can of air and sprayed the button until it was dry. I think that was my mistake because I think some alcohol got onto, or into the power IC located near the power button and fried something.
Looking for possible answers as to what could have caused this. The phone will not charge normally unless I boot into recovery/download mode. Plugging the phone in while powered off displays the charging icon with the grey battery and a circle in the middle but doesn't continue past that and reboots itself after a while. Tried a different battery as well and it's all the same symptoms which is why it's something internally.
On a side note, if anybody has experience with replacing the Power IC and would like to offer their service to me, we can arrange a price and continue from there. Please be a reputable member though. Thanks for reading. Hope to resolve this annoying issue.
If you are able to go into recovery mode, have you maybe considered flashing a new ROM?
Do you have some sort of custom recovery? If yes, maybe you could first back up all your stuff to an SD card (in case nothing helps bring the phone back to life).
Since your boot up logo shows up, but the ROM doesn't seem to start, to me it looks like your onboard flash memory might be the problem, not the power IC. The S4 is actually an awesome phone from a repairability standpoint.
Best of Luck! :good:
I will be starting to do power IC replacements in these phone in a couple weeks actually! I have a little cell repair business that i started a few months ago, but I have never done this specific repair. It isn't difficult, and as soon as I have a few successful attempts under my belt I will update you! Although, usually the phone won't boot at all if it has a bad power IC. I would do more research and see what can cause your specific problem. Feel free to message me or just reply on here with questions

Hi Deke. Sorry for not replying sooner. Kind of forgot about this thread after giving up on trying to fix it. But if you are willing to repair it in the future please let me know! I'll give you some business for your repair shop. Congrats on starting one too .
As for the phone not powering on at all if the problem was the power IC, that's what I thought at first too. But after getting a new power button installed and the problem still persisted, the power IC was the next option.

Z5P bricked after 3 vibrations reset... No chance for repair service nor warranty(UB)

Hello!
Well, I had the really bad luck of a very bad hard brick... my xperia was on low battery (around 15%) the last time that I use it, then around 20min later I got it and try to check, but screen didn't turn on, and the Led was blinking White color, since I deal in the past with this issues (around 3 or 4 times), I connect the usb cable to power adapter and simply did the reset button under sim flap, and my phone made the normal 3 vibrations, so, I hope that everything was fine, however, after that, I simply try turn on it, but never happen, No led of charge, no more vibrations and no power on, no signal of operation at all... so, I test remove and reconnect the usb cable and nothing, so, I try make another sim flap reset button test, but at this time and until now, no more 3 vibrations response and nothing else... and now, after reading some many posts, and try everything suggested in other posts about I really sad and hope for some help or feedback, if somebody may help...
By now I tested on my windows 7 notebook, and at first the phone was not recognized by drivers however it shows the bad message QHUSB_BULK error usb device, in later attempts, I made after some buttons tests looking for some response I got the phone change the messague, at the moment of connect it with usb cable to my pc, it was recognized as SEMC Flash Device... In both cases windows didnt allow or recognized for a proper driver installation....
But after other attempts, I lost the SEMC Flash Device status, and by now not remember what I did to get this mode or if it may be of some help...
By now I am really worry, since I got my phone from Hong Kong, and it came and worked fine until today, but in my country there is no service for this model since it not still on sale at official dealers/ carriers, and I believe that I don't have warranty service (since is an international purchase and not on local dealer) and also because I Unlock Bootloader for getting root and Sony records that information for warranty purposes (since I unlocked BL, I installed TWRP then I installed the romAUR custom rom and I upgraded it to 1.25 version with last kernel available from the same rom thread but thas was a month ago and phone worked fine after all custom rom installation)...
By now, I would like to ask if may be possible please, some guidance and help...
1) I was made attempts by the last 6 hours after brick without luck, and I wonder and suppose that the battery may be very low, but since I don't get any charging led, I wonder if by left It connected to the original sony charger with original sony cable (almost new and working both, and also tested both with other cell), my bricked phone may still get some charge on the battery.... somebody konws if possible to charge an xperia bricked?... I wonder/hope about that, if may be a charged battery may help in got the 3 vibes reset again that I hope may fix the issue and return my phone to boot...
2) Since seems that i don't have chance to get repair service on warranty since I unlocked my phone (and in my country the cost service for such model could easily be so high as almost a new phone), and also low chance for a warranty replacement from seller, I wonder about take the chance of open it and try to remove battery connector at a last resort since , I may suppose that this may allow for clear internal electrical charged registers of system and may allow me for a reset, but I wonder if the white flap sim buttons really did the same, that is simply open the battery connections, but, I doubt about that, since in this procedure the cel made 3 vibes and the energy for the vibes need to come form a connected battery...
3) May somebody with more luck, knowledge and experience, may suggest or share some help or advice about this issue...
I am a long time cell phone fan and long time in the issues of unlocking and installing custom roms, but until today, and after I survived many other phones bricks, my highest and loved phone of all my time, is bricked in a way that I am start to desperate, since I almost no clue by now about what could I try looking for a fix....
So, thanks in advance and if some body may help, I would be very grateful....
Is there really a reset button under the sim flap? Maybe you damaged the internals when trying this..

Yes, I've used it many times it's highly unlikely to damage it from that. Unless you press it harder than a gentle touch.

Yes, there it is, well, by now I am collecting more info and try about fully discharge my phone in order to get a RED permanent charging Led light (for future reference, seems that a Pulsing RED charging led means NO detection of battery...), by no today at morning I put my phone on charger and it only warn a little, and according with some info, the best chance by now is to plug it for a long time (other models of xperia reports around wait 24+ hours for get a RED permanent light...)
By now, I already purchased a set of adhesive gaskets, in preparation to open my phone (I did in the past and have some skills for doing it, but not that I really like to do over a so new and expensive phone... ), since by now, if I fail in got a RED permanent charging light, seems that the next step is to open back cover a remove battery connector, plug in usb cable connected to wall charger and then after 3 minutes wait, reconnect battery connector with the usb cable still attached, this would reset a really brick phone, and suppose tho reset the charging process of xperias...
By now, and in case of help other people that may need it now or in future, the guide that I am following advice is this:
[GUIDE] Recover 2012 and newer XPERIAs from SOFT-brick
http://forum.xda-developers.com/showthread.php?t=1849170
The info in the page seems with lots of sense, and the charging process description seems very similar at I would believe could be used in my previously Z2 and my now in comma, Z5P.... But by now, I need to get a RED light in order to try to unbrick without need to open back cover glass....
Any info, advice, comments or better, experience share, would be very gratefull...
Best regards...
Did you ever solve the problem? My Z5 died and wont turn on. Flashing lights when the usb is plugged in. Tried unplugging the battery and charging for hours
you have no fastboot ( vol+ blue led ) and no flashmode ( vol- green led )?
No, only a flashing red light when plugged in. The phone dos not react to any buttons.
Sony Xperia Companion does not recognize the phone.
"lsusb" in linux shows nothing when i plug the phone in.

I know you probably have but did you try holding volume up and power to force reset it?
You say you couldn't get a proper installation of hardware, so the computer can see the device? Is it showing an exclamation point next to the device driver?

Edit: Go to device manager and right click phone and do update drivers.
Click browse for update yourself and direct it to WINDOWS/INF folder and check "include subfolders".
Then click where it says "let me pick from a list of device drivers on my computer"
Then click Android phone from the list and click MTP USB driver and click OK for install.
Your phone should be installed correctly.
Then try fastboot etc.

someone gave me a bricked phone, how can i fix?

So someone gave me a bricked Sony experia m5, i believe that's what it is. When i plug in a charger the red light comes on but i cannot turn on the phone. i tried holding the power off button next to the sim slot for 10+ seconds but that didn't help either. I also tried holding the power on button with the volume down to no avail. I did some googling and found im not the only one with this issue. Altough advice was hard to find i managed to find a video about the same issue on a z3. As in the video i opened up the phone, reconnected all of the connectors. I left the battery connector out, then plugged it in and try to start it. Still didn't work.
I have never used a sony phone before and i have no idea what i should do next, i hope someone has advice for me
Repair centre unfortunately
