I am having a problem with my xperia x10 mini, the problem is not just mine. Apparently it is general.
Basically the phone doesn't turn on with certain SIM cards, if you press the on button the phone vibrates a bit but the screen stays black. If you remove the SIM card the SE logo appears and everything is normal.
There is a method to turn on the phone using PC Companion, once the phone is turned on everything is normal.
I have tested 15 different sims cards, 11 were the same model than mine, and didn't work, 4 were different model (1 year old) and the phone turn on normally.
The difference between the models is the golden part size, in the old ones it is bigger.
That is why I need to know if there is any way to debug the startup to find what the problem is or any boot log like /var/log/boot.log or /var/log/messages in the linux environment.
Thank you very much.
PS: My phone is rooted.

Hello all,
My rooted Galaxy S4 GT-i9505's display stopped working. It just so happened when I took my phone out of my pocket. The last app I remembered using was Whatsapp and I did not mess with any settings before that.
Powering on and off this phone feels normal with vibrations but there is no display and the Samsung boot animation does not show. Calling to this phone works, with vibrations. Touch does not seem to be working as I tried to unlock the phone using pattern lock and there is no feedback. I am also able to detect the phone in my laptop but unable to access files as I am unable to unlock it.
I tried booting into Recovery/Download mode but it does not show anything. I have also pulled out the battery numerous times but the display still doesn't work.
Very looks like time to repair that phone, there are many phones likes that with board problem, just make sure LCD is not cracked, the bring it to local repair center do replace one component on the PBA.
I bought an i9505x from eBay, before realising that the "x" signified a shop display demo model, which has the SIM socket disabled.
I then bought a working, unlocked i9505 logic board from eBay to replace the dummy one.
I received both and the demo unit was in immaculate condition, booted and displayed "Galaxy S5, Live Demo" on splash screen startup. Everything worked apart from SIM of course. All sensors, camera, WiFi... everything apart from mobile networking.
I then swapped the demo board for the full logic board (and added the thin antenna cable that runs down the side of the screen as this wasn't present on the demo phone). The phone booted and received telephony and internet from both the giffgaff and three SIM cards I tried in it. Everything else worked.
I rooted/CWM'ed it and upgraded the ROM to 4.3 or 4.4 (can't remember which one) and it worked OK for maybe two days and I went to work. When I got back from work my girlfriend said it had been displaying green lines and dots on the screen so she turned it off and put it on charge.
I had a look and there were intermittent rolling pale green lines quickly moving up and down the screen on boot, with a few dots the same colour at seemingly random intervals. After leaving the battery out for 30 mins and putting on charge for 30 mins I managed to get it to boot into ROM and all seemed well until I tried to reboot and the lines/dots happened again, with the dots getting worse.
In a tiny font on the display it seemed to have a line of text, but as it was so small and scrolling about I couldn't read it. A couple of boots later and the screen is totally blank.
I've flashed a stock 4.3 ROM on it by guessing the download key combination, as there's no display for download mode. Odin responded correctly, showed a connected device and went through the ten minute flash process and rebooted the phone.
The phone now boots and makes the Samsung startup tune and once booted I get the volume adjust bleeps when I press volume up/down so I know the ROM has booted but the screen is totally dead. I even get the initial blue LED for a couple of seconds on boot.
I'm going to try swapping the demo board back in today to prove if the screen is dead or not.
If the screen is OK then could it be the GPU portion of the logic board?
If so, what are the chances of me swapping chips around? I imagine this would be an impossibly tricky job to do at home.
Thanks for reading.
How much have you laid out so far £££ ?
Hi, guys,
I have following problem with my G2 D802, yesterday I left my on the front seat of the car, it was sun and hot, 15 minutes after that I take it, the phone was shut-ed down. After pressing power button the phone restart several times and boot without network connection. I read for possible solutions and found that if I left phone turned of without sim for a few minutes after that the device will recognize the sim and it's happened, unfortunately for a 5 minutes, after that the phone restarts and display massage insert proper sim card. Several times I restore factory settings, without susses. The phone display message service disabled.
The phone is bought from Vodafon Uk, and was unlocked with code from internet, works properly for a 6 months. The phone is not rooted.
Thank you in advance for your help.

Hi,
I just found solution, the problem was in the sim card, I ask my provider to change it and now everything is ok . It's more curios for me that other phone works properly with the same sim.
Has this happened to anyone else.
Had phone for 2 weeks now & I keep getting a no sim card error when my phone comes out of the lock screen.
I installed a keep screen on app & as long as the phone does not go into lock screen the sim is fine but if i let it go into lock screen after a few minutes when i open phone i get No sim card inserted message.
Any ideas. This sounds more like a software issue than a hardware issue to me.
Cheers.

Yes I sounds like a software issue try installing new software and see how that goes if not I would take the phone back for a replacement
I've had exactly the same problem with my LG Urbane 2 and the problem has occurred over three units. I assume that it's gonna take a firmware update to fix this. Right now I have to do a power cycle reset for a temporary fix.
What's a power cycle reset?
Hello developers and my fellow xda members i would like to ask for your help on this matter my yureka plus has been hard bricked since 20 days now and no matter what i try it wont get unbricked.
how did it happen??
well even i dont know actually i had recently flashed an 8.1.0 oreo rom known as nitrogen os and it ran well for like a week till one fateful thursday i have a habit of cleaning my device with clean master and restarting it every week and i did that and the next thing i know my device wont boot up later on i found out for the very first time my device had hardbriccked with no mistake of mine.
link to the rom i used :: https://forum.xda-developers.com/yureka/development/rom-nitrogenos-t3701962
what solutions did you try??
well, many actually since this is the only device i have and i have been using it for a well over 2 years now i did the good ol google search accompanied by a youtube search to find out how to get my beloved device back.
these r all the methods that i used which ended up "successful" but my device refuses to boot up even though i have followed every one of these tutorials to revive my device perfectly even repeating the process 2-3 times thinking i did something wrong but to no avail the device still refuses to get unbricked.
links to the methods i tried :: https://forum.xda-developers.com/yureka/help/guide-unbrick-hard-bricked-yureka-t3303112 (claims to have unbricked his device 3 times didnt work for me though)
https://www.youtube.com/watch?v=1n1qTpVvOZ0 (claims to have helped 10 other people get thier device back with this same method again didnt work for me)
what r the devices symptoms ??
well, let me see there r many although i have scoured the internet for the past couple of weeks i havent found a single person with the same symptoms as mine.
when the sd card (on which the emmc is still burned on) is out of the device no matter how long you press the power button the device will not show any signs just nothing.
when put on charging or connected to the laptop (without the sd card) though it just shows that dreaded little red notification light and thats all.
with the sd card in and emmc burned onto it the device when holding the power button will just flash the screen with nothing but just a black screen no text no logo just a plain black flashing screen until i let go of the power button.
when plugged in to a laptop or a charger with the emmc in though the device vibrates goes into the "fastboot mode" with all the lines automatically without me doing nothing just plugging it in and it doesnt stop there it keeps repeating the cycle of vibrating going into the fastboot mode then going off till i take the cable off.
but the laptop doesnt detect it as anything not as "qhusb bulk" not as "qloader 9008" not even as an unknown device even though i have installed all the drivers neccessary and more.
the device has been in this state since well over 20 days now and i cannot for the life of me am able to revive it so i ask for everyones help for i will b forever grateful if u help me get this device back.
also, i refuse to believe its any hardware problem since the device has never fell off from my hand ever since i bought it over 2 years ago.
I was having a similar problem what is ur model name was it android one or cyanogen one.
If it was android one then flash this file with ydgp tool
If it doesn't start then to try to boot using charger connected
If the booting process starts or it show yu logo after yureka plus logo that means it's your battery problem
