Hello. I read your posts about xperia z2. Unfortunately nothing is working. I don't know too much about the phone because is not mine. It's possible to have taken some water inside. At the moment no matter what I do, only the red led turn on when I plug it to wall charger or usb pc. It is not responding to any buttons or hard reset button under the sim slot. Most of the post are about flashing. But how can I flash if the button are not working? When I open it the battery had 3v. I charged it to 4,2 v but still not working. I also tried with the battery cable unplugged. Do you think there is still something I can try at this moment or it's batter to buy a new motherboard? Thank you in advance.
Have you tried to hard reset using power and volume up? Have you tried to flash via flash tool? If that doesn't work I'm afraid you have to buy a new motherboard.

Hold volume down while pluggin in the usb cable (connected to pc).
LED should turn Green, then you are in flashmode. If pc recognizes phone, try to flash a stock tft firmware.
Thank you for your answer. As I said, the phone is not responding to any button inputs. I tried power,volume -,+,red button under sim tray nothing is working. The only thing it does is the red led turning on when I plug it to usb. I read that a new battery could turn it on. I think the battery is good as long as it holds voltage.
At this moment I am trying the rubber band trick. If this doesn't work probably I need to change the mother board. I looked at the mother board and I can't see any damage (broken connectors, traces of fire...)

I have same problem. Maybe do you know solution? I think this is mb problem, but maybe know how to fix it?

looks like just flash red led, no charging. When trying to turn on I can hear some clicking sound from motherboard, like small relay or something.

Hi all,
A friend on Frandroid Forum, post the problem how to Fix "Battery Low - Cannot program" with Fasboot mode ... I see more post on defy, milestone, etc... but with the RAZR XT910 .. can't open and see the batterie....
Could you give your me an idea please ??
Sorry for my bad english
I post on the Defy thread too
Thanks in advance !!
Is your phone stuck or something? if it low battery then charge it up?
Thanks for your answer.
Apparently my friend charge all night, he just see a white led loading and this message when starting in fastboot!
He charge on PC so I advised him to use a charger rather and wait very long time ...
You must be charged before you attempt any flashing.
If the phone will boot normally you will need to boot it, let it charge, then flash.
If it it bricked, you may be out of luck.
Get out of the "Fastboot" menu and try to charge it.

You are welcome (You must speak english here !! but I understand !)
i have the same problem only mine is worse:
got a gsm razr XT910 and accidentally formatted the system (i know very stupid move). In this case i believe a simple flash using RSD lite would work? ( -question because I've never done it before) but the problem was that i didn't have a pc nearby for a while. I tried switching it off but whatever i did it just booted back up so all the battery drained.. (i think i've found out how to force it to switch off now but thats not the point)
the point is that it was off completely, when i plug it into the wall charger it just tries to boot with the 'M' logo stuck on my screen, the LED is off and there's no charging going on. If i take it out of the charger at any point it just dies and doesn't start again unless i plug it in no matter how long it's been "charging".
The only thing that does happen where i see some hope is when i plug it into the pc now the screen remains black and the LED is white, after a while i can unplug it and it will work without the charger so i assume it charges through my pc. the thing is though, when i leave it plugged in every hour or so it tries to boot by itself and the LED becomes dark(not charging), left it like this overnight and it was dead in the morning. What i do to solve that is whenever it starts booting i switch it off and plug in again then its the same, LED on, screen off.
Using the PC method i can wait for like twenty minutes and then it has enough power for me to put it into the fastboot mode however it displays the "low battery cannot program" message and i can't flash using RSD..
My plan for now is to keep doing that hoping that it will charge this way, however its been 7 hours and it still tells me the battery low message...
Does anyone know anything that would help me? Any help will be so appreciated!
I heard of using a 'factory cable' but I'm not sure where to buy it and don't have the electronics equipment to make one. I live in london uk so maybe someone here who has one could help me out? Seriously at this point: any help any advice will be worth a lot,
Thanks in advance
Hi,
To make a factory cable you can see this thread
and if you want buy one ... see this link !!
Have a nice day.
this link is only for american deliveries I'm an London man!
Create your own cable !!! It's not very difficult !
he's talking about using a solder station to melt the wires together, i don't have that..
USB Cable
This happened to me and I had to jump it with a USB cable.
Here is what I did:
Take a standard USB cable and cut off a section of wire with the larger connector ( the side that connects to the computer).
Strip the outer shell exposing 4 small wires (2data, 2 power).
Tie off the Green and white wires and strip the Red and Black.
Remove the back from your Razr and connect the Red wire to the + and the Black to the - terminal of your Battery (they're marked).
Plug in the USB and boot into Fastboot.
Connect your standard Data cable to the phone and do your thing.
Just saying....
There's actually a thread in the RAZR Development section. You could have found it in seconds if you searched for it instead of directly creating a new thread.

Thanks for the advice although i have a couple of questions:
-After cutting off the part of the cable we keep the large usb end right?
-What do you mean by the outer shell? The part that actually goes into the computer? or the casing of the cable on the cut off side?
Thanks
Yes, you keep the larger end that connects to the computer.
Strip the outer wire to reveal the 4 colored inner wires.

I've done that, and i'll connect the wires to the battery screws in a sec and then i plug it in to the charger? and a normal usb to the pc as well?
uhhh..
No, don't plug it into the wall charger at all.. That's crazy talk.
Just plug both USB cables into your computer and fire up Fastboot.
keeps saying "failed flashing process, phone returned fail"
what is wrong now?? everything should be fine
ok
I'm assuming you're referring to a massage being displayed by RSD when run on your computer?
Walk me through your process in detail. What does your phone say when this happens?
How did you connect the USB to your battery? If you didn't make a secure enough connection it won't provide enough juice. You need clean wires and a secure connection. I loosened the battery terminal screws and connected the wires directly to the terminals then tightened the screws and it worked without issue.
Need a little more information before I know exactly what's going on.
alright so i screwed the wires to the terminal of the battery and then plugged it into the computer, i wasn't sure what was supposed to happen and when nothing did for a while i plugged it into the wall charger and it started booting up.(i know you advised not to do it but i did it before reading your post) In fast boot menu at that point it would tell me "battery ok". So i went on and tried to plug it into the pc ac well with a normal cable and everything was fine RSD lite saw it i extracted the fast boot files and then when i press start it comes back with the fail error and stops straight away on the first step. I tried flashing different versions of the software and no good. I waited for my battery to charge (it now says battery ok even when unplugged ) still no good. Then read your post and did it the way you explained, still no good. Exactly the same error every time. And if i press the peer button while in fast boot to power off it would come back to ap fast boot by itself and at the top it would say "flash failed" or something like that. I tries re-installing the ADK tools or whatever its called and still nothing.
So i found a very good russian website that explains how to use moto-fastboot to install the system.img through the terminal and i have everything and the fast boot thing is on c:\ directly and i go into the terminal as an admin and whenever i write in moto-fastboot it comes back with "moto-fastboot isn't recognized as an internal or external command..." no matter what i do.. i've looked for a solution the whole day, can someone please help me
Thanks
I've just received a cracked s2 gt-i9100 the screen was cracked and didn't show an image but still the buttons lit up and the phone vibrated on touch i ordered a new screen and set about replacing it unfortunately upon doing so I snapped the power button ribbon cable so i'm unable to power up the g2 till the new one arrives, when i plug my phone into my laptop the screen turns on and shows a battery charging however the laptop keeps saying unknown device... I've tried different cables and a different laptop not sure if i could of damaged the usb or if it might be that there is no power button ribbon connected?!
Would really love any help? like maybe there is a way to turn the phone on without the power button for the moment?
Have you installed all the necessary drivers for the phone?

I don't think the power ribbon cable have anything to do with the phone not being recognized by the computer, but everything is possible. Are you sure you didn't mess up anything inside the phone, when replacing the screen?

Hi,
Please, be patient while reading this post, this is a looong explanation of the brick I am facing...
I recently was given a non working XTZ SGP311 and tried to get it back to life. As I have another one SGP311 (this one is perfectly working), I am able to check many things.
I read most of topics about XTZ unbrick but can't find any way to get it back working.
The problem is that I can't have any signal from usb (data or power). I use a genuine Sony USB cable and genuine Sony charging adapter (coming from the working SGP311). The led always stays off.
I tried the different combos as described (vol- and power ; vol+ and power ; vol+ and vol- and power) during 5, 10, 20, 30 seconds (yes, quite complete tests).
I did a cross check of batteries and inside usb connector ribbon (yes, had to open both tablets for that), the working tablet continues to work with the 2 parts coming from the faulty one (battery coming from dead tablet was 0% charged), so the problem is not on the side of the inside usb connector neither on the side of a supposed dead battery. The faulty tablet doesn't boot, even with a fully charged battery inside.
I luckily own a XTZ dock (SGPDS5) that allows to charge without using usb connector (it uses the 2 contacts located on the left side of the tablet). That's the only way to get something...
Soooo, when I put the bricked tablet on its dock, the red led flashes very slowy (say, 1 second off, 1 second on red, and so on).
When I press vol- and power, nothing happens (no matter 5/10/15/20/25 seconds).
When I press vol- and vol+ and power, idem.
When I press vol+ and power : I got the sequence blinks once white led / blinks 3 times white led (after that goes to slow red blinking about if I keep the keys pressed). So not completely dead.
If I unplug it from the dock right after the third white blink, plug the usb cable to the tablet, plug it to my laptop (with emma running, tried with pc companion too), and press vol-, then....nothing happens. Really nothing. No led lit. No detection of anything from the laptop (or device manager as well). It would have been the same if I would have kept it unplugged.
To sum it up, the only thing I can have is 1 or 3 white blinks after having plugged the SGP311 on its docks.
IMO, the trouble comes from a faulty component inside the tablet. Maybe the one that manages the connection from the usb ribbon plug. I checked the tiny plugs inside the tablet (once dismantled and back repacked too), all seems in order.
Your help is welcome !
This is similar to an issue I have it sounds like, you can still flash stock rom by holding power + volume till it blinks 3x then plug USB in and hold volume down immediately.
This gives flash mode, you can use flash tool to put stock rom on with this. The issue happens when it's acting like there's no OS it seems. Problem is mines doing this everytime I flash a custom rom, it's fine with stock aside from **** wifi
Thanks for your help. I tried that yesterday and it did not work.
This may be related to the way of reset I use (but I can't have any other).
As I can't get any white blinking led when connected by the tablet micro-usb port, the one and only way to get the 3 times white blinking led is when the XTZ is on its dock (SGP DS5, power connection only by lateral contacts).
What I tried yesterday was to get the 3 time white blinking led (vol+ and Power), then output the tablet off the dock and connect a usb cable to a laptop running Sony Emma (from micro usb tablet port to usb laptop).
Precision : I kept VOL- pressed when pluging usb cable to laptop.
No result at all. No detection (either Emma nor windows).
Any idea ?

Thanks for your advice, I appreciate.
But I swapped batteries from the working XTZ to the non-working one and put a (about) 60% charged battery into the bricked XTZ (both batteries are charging when set into the working XTZ). I will try anyway.
The problem is that the non working XTZ does not charge either through usb or through the dock. The only interest of the dock is that this is only situation where I can have the "triple white led blink" (but nothing more).
That's why I need the working XTZ for charging before doing anything with the non working one.
What I could try would be to connect the lateral contacts with wires to the dock in order to keep an access to the usb tablet micro port and connect it to a laptop.
But this may be hairy as this would give 2 ways for power (one by the dock and the other by the USB port), and may produce a short circuit...
Any XTZ power experts around ?

Well, not a real solution...
I bought a cheap xtz with broken screen and got its working motherboard and put it instead of the other one.I got the lte component too with its antenna and put it into the 1st xtz that was not supposed to have lte.
So now, on one side I have a xtz with faulty motherboard and broken screen, and on the other side a refurbished xtz with LTE !
I like very much this tablet. Very handy, easy to dismantle and easy to swap its components.
The only drawback is no more support for Sony.
Thank you for the answer
So, you are saying that if I replace the motherboard I can fix that ? I'm looking for motherboard on ebay and I found one for $28 usd + shihpping.
Thank you for answering and take care.

Yes. I think this should be good.
Don't care about the exact matching of the product code: as long as it'll be xtz, it'll be good (16 or 32 gb, with or without lte, and any region should match).
Did you opened it already ?
Yes, I opened 2 years ago cuz my son broke the power jack connector then I replaced that twice.
I'm also tech guy, I can replace that, but won't expend more than $50 for a new motherboard. I'm looking on ebay now.
Thank you

So i found a usb cable at work so i decided to take it home and use it. When I plugged my tablet in, it seemed a bit loose so I decided not to use it. But when I plugged my original charger, it wouldnt charge....that was 2 days ago and still no charge.
Im pretty sure its bricked because it doesnt turn on, doesnt show its charging...nothing. I guess i just want someone else to tell me that its done for and time throw it away or maybe have someone more knowledgeable repair it..

So what makes you think it's a brick? Is it just a dead battery? Did it boot before? Have you opened it to check the battery connection?
I replaced the USB daughterboard on mine. Like $10 and 15 minutes. Couple screws and ribbon cables

Does the white light at the bottom flash when you try to power it on while it charges?
try this:
Plug your N9 into a good 2.4amp output USB brick
hold down the power button
If the led doesn't flash 3 times annoyingly then you are out of luck. I don't know how to fix it. I have a broken N9 and a good one and the broken one has a dead mother board and sounds the same, but I DOUBT a loose USB cord destroyed your tab.

Mine died too, but the led does flash 3 times. Is that a good sign? My USB port began failing and it was getting harder to charge. I left it plugged in over the weekend (forgot about it) and on Monday.... Nothing. But it does flash the led 3 times when I plug it in, sometimes. I probably need to replace the USB board again. Leaving a USB otg stick plugged into it for movie viewing in the truck is what keeps damaging my USB ports.
Update: I finally got it to charge and boot. Just had to hold the cord just right, and plug it into an outlet I have converted to USB next to my couch. New USB daughterboard ordered and on the way.
Try putting it in APX mode and charging it. Plug it into a computer and hold power, vol+, and vol- until the tablet is detected. Leave it overnight, then hold the same button combo for 15 seconds.
I have a problem with my LeMax 2. I was using google camera for some picture taking, and all of a sudden phone shuts down. I connected it to the charger, thinking that the battery is dead, but all I can see is backlight, without anything on the screen.
then I connected it to a computer, and there was a popup that said: "the last device you connected to this computer malfunctioned". it seems that USB cable is burnt out. I changed the USB cable, but the same error occurs.
The strange part is that i get notifications, I can locate the phone via Find my device, but i can't see anything on the screen, only i can see a backlight. PC does not recognize it, i tried Linux, win10, win7, USB OTG. i ordered a new Dock Connector Charging Port Flex Cable https://www.aliexpress.com/item/Original-New-Dock-Connector-Charging-Port-Flex-Cable-For-Letv-leEco-Le-Max2-Max-2-X820/32828762033.html?spm=a2g0s.9042311.0.0.116b4c4ds9GGuN, and changed it, but the problem persists.
i can only see backlight, the phone can be located, the notifications can be heard, but USB is only good for charging, even after replacing it.
Does anybody have some idea how to revive it?
Heyyo, hmm does tapping the power button allow the backlight to at least work? Please rest that in a dark room to see if you can notice the backlight.
If not? It could be a hardware issue... You could try heating the device with a heat gun and then using a suction cup or screen seperation tool and then check the connection of the screen to the device and ensure it is properly connected.
There could be other recommendations if someone else also has an idea
Yes, the backlight works. I opened phone, changed USB port and checked the screen connection. Firstly I thought that USB is fried due to some weird power surge when connecting the charger, but after changing the USB, it is the same.
The next thing that came to my mind is that USB connection on motherboard is fried. As I said, the phone charges up, but when connected to pc, it shows that device has malfunctioned. The screen has backlight, as far I can say it registers a touch, device finder can locate it, sound works...
