Hi guys,
I have a problem with my x10 mini pro. There are some similar posts here but nobody exactly describe what is happening to me. So my problem:
One day i have been in subway, phone working properly everything fine. THan suddenly 3G icon has disappear and wouldnt go back. So i decided to restart the device. But since i turned it off, i cannot turn it back on again...
I have tried to take out the simcard, take out mempory card, multiple time reflash by SEUS but still cannot turn it on.
I cna charge the phone with no problem, i can flash it with no problem, but i cannot use it at all.
When i press power button, phone shortly vibrate as he is turning on, than display get a bit brighter (not white, just lights up its easy to notice from profile). and than after few seconds get black again. And like this it continue until it drains battery, only without vibrating. every cca 5 seconds display light up and than get black again. So i guess its rebooting all the time. I have tried all tricks like pressing power+home button, still nothing.
I think i just need really wipe out the whole phone and flash it again. Is it possible somehow? I feel like reflashing by SEUS is not real hardcore flash, is there anything stronger i can try?
I am willing to try anything if anybody has an idea, since its not working anyway so i dont care what i try.
Thanks for advices !
http://i.imgur.com/eYhCtMr.jpg?1There are many people that changed their LCD (Z, Z2 ,Z3) and then were unable to startup the phone.
Of course one might think, is the display broken, did I mess it up myself, etc etc...
Here are the symptoms. If you have the same symptoms, then this will fix your Z2!
- the phone does not boot. Black screen. Will not do anything else then 3 blinks when you press the power on
- without battery, and cable in a charger (not in computer!), will show a battery logo on the LCD
- with battery in the phone and cable in a charger (not in computer!), will make the "Im charging the battery"-light burn red and after a number of seconds (but not always?) a bit dimmed red.
- the phone vibrates if you do the trick with holding the on button and the volume button and keep them pressed (without battery), but nothing more will happen.
- adb does not recognise the phone at all. Fastboot does, but ONLY without battery
- the battery is fully charged, and NOT the problem
- you can flash, unlock the bootloader etc, but only without the battery
- changing the battery with a new one, does not solve the problem.
You have all that? Great..
- open the back of the phone (probably still open )
- take the battery out and concentrate on the part where the battery connector is.
- take a deep breath and keep calm
- solder a very tiny, thin cable from one part to the other (look at the picture).
If the picture is not clear enough, just ask, and I will answer as soon as I can.

Thats all folks! worked for me! I couldnt believe my eyes, but it worked!
All thanks goes to Ahmed Koukou from Egypt who uploaded the solution on another forum, but without any tips and without description.
Registered specially to thank you and to confirm that it worked for me!!!
I bought a new display of Ebay. At first, I thought that it was a bad display, until I read that others had the same problem.
Thank you! My Z2 is alive again :good::good::good::good::good::good:
Hmm interesting,
- the phone does not boot. Black screen. Will not do anything else then 3 blinks when you press the power on
No 3 Blinks just a solid RED LED
- without battery, and cable in a charger (not in computer!), will show a battery logo on the LCD
No battery logo on the LCD just a solid RED LED
- with battery in the phone and cable in a charger (not in computer!), will make the "Im charging the battery"-light burn red and after a number of seconds (but not always?) a bit dimmed red.
Always a bright red led
- the phone vibrates if you do the trick with holding the on button and the volume button and keep them pressed (without battery), but nothing more will happen.
No vibration, even tried the elastic band trick
- adb does not recognise the phone at all. Fastboot does, but ONLY without battery
If only if the PC would recognise something connected. so no adb
- the battery is fully charged, and NOT the problem
- you can flash, unlock the bootloader etc, but only without the battery
- changing the battery with a new one, does not solve the problem.
Thanks i was going to try that
wow this is very similar to this post back 2 years ago

I am going to have a look at mine
Good luck! Hope you will find a way to get the Z2 to work again!
Well i tried this trick and it worked however today after many months the phone just will no longer charge. The battery is in good condition etc but the charge is just too slow to give it enough power.
I cannot work out why it does not charge at full speed any more
My Z2 has been lying dead in a drawer for over a year now. I thought it was gone for good so I thought what the hell it can't get worse than it is so I gave this a try and it ****ing worked!!
I registered just to say Thanks. My Z2 is alive again :good::good:
it works!
It works. thank you so much. I was so attached to my z2 that I bought an original sony screen for replacement. Imagine the deception with these blinking lights. I would like to know why this needs to be done? anyone?
Hello,
after reading your solution I tried to get a very tiny cable for connecting the two points. I didn't have enough patience getting it working.
After trying it without success, I remembered in past, I had to modify AMD CPUs to overclock them. There I used a simple pencil making a line to connect them.
I didn't think long about that, then simply tried it, and had luck with it. My Z2 is now booting again! I'm happy with my solution!
Hope this will help some other people, who also don't have enough patience.

I am also happy that I could help others by creating a manual.
Enjoy your reborn Z2

Million thanks, it worked. I had the phone broken for years and this fixed it. Though it was hard to solder.
Thank you
Just wanted to say thank you for this solution.
I had a similar issue when I put a new battery in it wouldn't turn on. I had the three blinking red lights.
No I have done this it works.
I used Car Window Demister Repair Solution liquid and it work just as well. Got a little puff of smoke but appears to be working okay now.
Again thank you for your help.
you are genius...totally work
Hello everyone. I am also desperate and I came across this solution. I bought the soldering tools however I was unable to do it so I wanted to ask you more about the process. What wire did you use to connect two points? I have 0.8mm soldering wire and it seems to be too fat for this. Also, the guy mention that he did it with pencil. How?
Thanks in advance
It helped me too. Was Xperia Z2, worked well before display replacement, battery at 3,95V, despite of it three red blinks when attempting to start, glowing red while on DC, but not charging (power consumption 0,133A though). Sometimes three vibras when attempting to Power+VolUp while on DC. Black screen only, no logo no nothing.
I have a Lg G Pro 2. Few days back it got bricked by its own( a crazy fact). That time it was showing QHSUSB_BULK. I figured it out as 9006. Took the phone to a local service shop. Today I got it back and found that nothing had happened to the phone, except worse. Now it is not detected by PC, only green light blinks for some time if tried to power on. And then everything is black and cold as death.
I think it have been flashed with wrong ROM. Anybody here can guide me with the test points of Lg G Pro 2 (D838 F350) ? So that I can force it to QHSUSB_BULK ? Or any step by step advice to get it up ?
I am in real need of assistance, and thanks in advance for any sort of help. Best Regards.
I would like to mention that the phone indicator blinks for sometime if I try to power it on, as it does on boot, but nothing else is there. No recognition by PC, no presence in Device Manager. Blinks for sometime, stops, again starts blinking... and this goes on at regular short intervals. The area around the camera gets warm after sometime. Everything loops till I pull off battery.
Now, am I missing something ? Is the problem not as deadly as I am thinking ? Is it soft bricked ?

Hello, friends
Out of the blue, my S6 Edge tried to restart, but got stuck in a loop at the Samsung Logo. One or two times it went to "insert pin" and then restarted again. I tried to Force Restart and it didn't solve the problem.
After a few tries, I managed to wipe the cache partition. Now it's simply bricked with a black screen and a Solid White LED. I can't restart it, enter download mode or safe mode or anything. Odin doesn't recognize it at all. Is there anything I could try?
The phone is not rooted.

Hold only vol down + power for 20 seconds. Does the screen go off? Its not bricked otherwise you wouldnt even have the led lit. Theres hope

Thank you! Tried it. Doesn't work. It's beyond my understading why would it behave this way after I managed to clear the cache. At least before that it went into download mode or safe mode. I still suspect a software issue.

So vol down + home + power will not get you to download mode?
How about recovery? Vol up + home + power?
This happened to me before and the way i got out of it was hold only vol down + power as soon as the screen went off completely (no led lit) switch to download mode combo.
Tried both of the commands. They didn't work. I will let it drain the battery completely and then see what happens.

reminds me of the bad emmc memory like the note 4s had.
some times completly letting the battery drain can fix it being "stuck". then recharge for 20 min or so then trying to turn on.
if u plug it into pc does it reconize anything in device manager
even unknown device or descriptor failed anythiing at all?
This morning the LED was off, so I tried to recharge it. Nothing happens. Also, the PC doesn't detect it at all. I think it's safe to assume I need a new phone. Too bad...at least if I was able to recover the data on this.

you can thank sammy for no ext sd card for that one or more than likely pics would be on sd
now one last sollution is to try buying a cheap battery my note 5 had a issue it shut of one day and wouldnt do nothing i understand ures was blinkik and trying at least
so its a leap but last resort
same problem here started over a week ago - samsung S6: black screen, constant white led. tried all variations of resetting with buttons. over a year ago i replaced the battery, and its been fine since. when this no boot issued happened i also tried changing the battery to a known good one. on inserting a battery and then pressing the power button the indicator led will go to green for less than a second before changing to constant white, and it stays that way no matter what until the battery is drained or the battery is removed. Strange thing is there is no information from samsung on what this behaviour means, but I've come across dozens of other S6 owners on the web with the same problem, so this is obviously diagnostic behaviour designed by samsung - but no info from samsung. the phone has never been damaged or watered or rooted so I'm at a loss.
Confirmed diagnostics:
The phone will respond to the power button and attempt to turn on
The phone will charge a battery, so the charging circuits and battery circuits are working.
The phone does not get picked up by a Windows 10 PC with Kies installed in any state - other samsung phones get picked up no problem.
Same here
I have the same symptoms. When I hild the vol up+home+pwr I get a green let for 1/2 sec then white. No other combinations do a thing. I swapped the battery for a new one. No luck.
Mine started a few days ago. The phone was 50% charge and i plugged it in for two hours. Came back and it had a solid red led. After a few hours the red light went off. It was then 100% unresponsive. I then took it apart and disconnected the battery. When I reconnected it, it started to do the white let thing described above

I have one that behaves exactly the same I changed the battery and didn't make any difference. my next step is to replace power management chip. I'll let you know.
Any luck on this?
Mine has been like this for a couple months, kind of gave up on it, but decided to give it a go again!
Same problem here, just happend after switching the battery. Anyone have solved this?
I found a kinda solution, plug your charger in and charge past 30% then unplug charger. then use just vol down and power button for 7-10 seconds, after 7-10 seconds just release the power button while still holding vol down button until you see samsung logo, you can tell if you did it wrong by the solid led being back on, repeat until success, once you have it on do NOT press the power button or it will RESET back to solid led/black screen.
I have the same problem with my s6 active and similar story to dbeeheim. Has anyone fixed this? And can anyone confirm that enzo13's solution works?
Much thanks in advance!!
i have same problem!
Suddenly my S6 dead, battery was ~80%, no charge
yesterday i try to change battery, after that if push power button, LED small light comes but in white with purple, then stuck. (it's small Notifications LED)
and i chnge the screen, but no more than white/prople LED.
(no any thing on screen, always black..)
what is the problem?
i think it's battery because it last month didn't work good, and it's old 3years battery.. but no idea..
Hello guys my Samsung S6 sm-g920f has the solid white led and black screen. Really no fixes?
thank you
Same issue
I have the exact same issue. My Galaxy S6 Edge (G925F) suddenly died and won't get past the 'Galaxy S6 Edge Powered by Android' screen.
I am unable to reach the recovery options. I've tried flashing two different stock ROMs with Odin which succeed but without successfully turning on my phone. I've also tried flashing TWRP with success in Odin but it won't get past the 'Powered by Android' screen before turning off after +-4 seconds. The white LED is on even when the screen is black.
Just had this same issue, my battery died and I forgot to charge my phone overnight, woke up and it would not turn on, black screen. I did manage to replace the battery and do several diagnostic tests on it. My battery was receiving about half the power output it should be (this is normal it's a 4.5yo phone) and when I replaced the battery with a new one, it did not turn on. With wireless charging I can tell I am receiving a charge and with standard I can not. The screen does not indicate it is charging with either method but my wireless charging pad lights up indicating my phone is being charged. I think it may be the processor or screen itself. This really sucks because I lost all my data on my phone and data recovery can be over $500
Hi everyone,
I used a month ago my redmi note 4 before the job without worries.
During the morning I wanted to watch something on my phone and no way to turn it on.
Having charged the phone all night, I tell myself that this is not a charging problem.
I tried to restart my phone by pressing the long power button, recovery or fast boot and despite these 3 manipulations there I see only the notification led that lights up red intermittently as the power button is pressed.
I tried to find solutions but no way to find something that would change things.
I used revengeos for a month so it should not come from improper handling.
Can the phone be cracked like that when it worked a month or is it just a fault of the battery? I see only the red notification led when the cable is connected and no sign when it is not.
Battery has been changed and it's the same as before. I've bought an edl to test but no change.
I don't know if I do something wrong but I tested a lot of things found on google search.
Phone isn't recognised correctly in device manager error 43
What do you think of this problem and do you have a solution to offer me?
thank you in advance
Up
Do you know where I can find solutions about this problem?
Thx
