I have the drivers, I touched the two pins with many things, knives, metal things like nail clippers, eyebrow tweezers, and I could not get a pincer of those. I touch, I connect to the PC and nothing happens, I had the experience of everything.
I have the bootloader blocked and the mobile with bootlop.
What I can do? What can not you get other than that clamp to touch the two pins?
I've the sane problem, but NY phone Is completo dead, no boot logo, no vibration, no led... I menaged to flash once using test points buy It didn't boot up... Now of i wanted ti enter again edl i can't can't. Did you solve?

Hello
Recently i've bought an broken screen Xperia Z, for repair it (i got it like $300 bucks cheaper) and i was ready to buy the screen, but i battery was drained and i could not test it right, when i connected to the charger, it started red light, vibrate, then 3 continuous vibes, read on the internet, OK BATTERY DRAINED, i left it charge THE WHOLE NIGHT, and when i woke up in the morning it was orange (charging), later in the day it was green (charged) but when i disconnect it, it wont turn on anyways, when i connect it to a pc, it goes blue light (wich later i read it was fastboot mode). i read for making a repair with PCC, but it didnt fixed it, then i flashed it with Flashtool, with the latest software (wich had the Sudden death issue fixed) no luck. it wont boot. for it to boot, i have to connect it to PC and with fastboot run "fastboot continue", but most of the time, it reboots and goes redlight and vibrate 3 times then reboot, so i press the power button and it enters fastboot mode (if connected to PC) or loads charging if connected to wall charger, but it reboots again and goes to redlight vibrate reboot, sometimes it stay charging or in fastboot mode, but only "works" if connected in the USB.
when it stays in fastboot, i do "fastboot continue" and it loads the OS, and it works (well, the things i can do with a broken LCD/Touchscreen, i put my sim card and could call it, and it works, but i cant pick up the call). i can explore the phone memory etc. but if it reboots or if i disconnect the USB, it will almost always turn off. i havn't found a solution (or idea) of what can happen, i dont know if its normal since it has broken lcd/touchscreen or it definitely have a huge problem,
any ideas?
thanks in advance!
Maybe the battery is damaged, and the phone knows it and boots into some sort of safe mode to spare internal damage? When the is has booted you can take screenshots with adb if you have usb debugging enabled. Maybe try see if the os says the battery is damaged?

Well, actually it doesnt seem the battery is damaged, fisically looks ok and it holds charge, i cant debug because usb debugging comes off by default when flash stock software.

Correct me if i am wrong but does the xperia z not support usg-otg and mhl? You could rig the phone up to the tv with a mhl-hdmi cable and maybe use a usb mouse to select things, and enable usb debugging?

Nice idea, now i need to find who in this country (DR) have that adapter
i ordered the LCD screen assembly for repair it myself, but im still concerned about this, as i dont know if it will boot up anyways
my phone right now isnt booting. but as i cant see images i dont know what is it showing.
i noticed the touch screen is working indeed. (when booted, it plays sounds when tapping)
i will wait till the lcd assembly arrives. any ways, any other ideas on what may happen?
the ex-owner of the phone said it started like that when it fell and broke the lcd.
OK now, i've installed the LCD, the phone works, its ON, BUT the Volume Up button and the Power Button does not work when the phone is ON,
the Vol UP button seems always be pressed cause when i press the power button for some seconds, the Phone restarts and not power off or lock/unlock
Service tests: None of these buttons where recognized.
any ideas on any hardware fixes i could try?
I FIXED IT!!
dissasembled the phone, took out the side button flex cable and the volume up button on the flex was dirty, so it was having a false contact. (wich made the button always be pressed)
I took out the yellow tape and cleaned with alcohol and a needle (its so freakin small) and put the tape again and assembled the phone and voila! IT WORKS OK!!
Yes the vol up button pressed means u get fastboot. Now that you fixed the problem and repaired the phone enjoy. Btw nice job getting it up and running.

Today I replaced my cracked Redmi 4X screen. The replacement consisted of a screen+digitizer+frame assembly (no messing with a heat gun to detach screen+digitizer from frame). I think it went fairly well, took my time and didn't force anything.
However, when testing the screen halfway through reassembly, it was stuck on the mi logo. I decided to complete the reassembly, thinking maybe it did a hardware test and refused to boot as i hadn't reconnected all parts. No such luck, even when i use the old screen it doesn't boot .
The charging led also doesn't come on when attached to a charger or laptop usb port, which seems weird. I think the battery is about 50% but right now i can't even turn it off. It just reboots when holding the power button. It doesn't enter recovery when I hold the volume-up button. I do get a fastboot logo when booting with the volume-down button. But no response on the USB cable and the logo just stays on exactly like the mi logo in normal boot. I'm not sure but I think fastboot is supposed to show some kind of menu interface? Or is it normal to see a fastboot logo only?
I've read some other posts about Xiaomi phones using different brands of digitizers, having to clear the cache to reset it and accept a different brand, but when I detach the digitizer it doesn't boot either .
I could try a factory reset with mi flash but it requires Windows which i don't have easy access to (if it even detects the phone). Perhaps there's a way to rescue it that doesn't involve losing all data, i might as well just buy a new phone if i have to reinstall/configure everything. anyway.
Any ideas?
Edit: I was suspicious of the power/volume contacts issue, so I lifted the board and was able to flash with EDL and enter the system. I might've messed up the piece while removing it from the older case. I ordered a replacement and I'll see how it goes from there.
Edit: the issue was indeed the flex cable of the side buttons. I replaced it and now it works!

Hey guys, my phone's back cover and screen got shattered recently but it seemed to be working fine. I got some parts from China and assembled it today, I think it all went ok, but now the phone's stuck in an infinite bootloop (Android One screen).
So, the phone's bootloader is locked. I can't do anything through fastboot, even though I can try to send commands. Every command just reboots the phone and returns it to the loop.
After reading a lot here, I heard that my best bet was to enter EDL mode and flash the phone with MiFlash.
I'm able to get to EDL (phone shows up as COM), but after that it all goes downhill, I get a different error for each attempt of flashing: timeout, I/O exception, writing time out, resource in use, port closed, phone disconnected, strange errors, handshake error, reset status error etc.
It begins normally, flashing a few things for half a second, then fails.
I've tried two computers, multiple USB 2 and 3 ports, two images, two versions of MiFlash, three cables.
What do you guys think? This EDL flashing should've worked, but it's keen on failing in every attempt till now.
Funny thing is, while messing with the connectors, once in a few dozen loops the phone actually boots to the system, then reboots after a few seconds!
Also, I should mention that I can't turn off it for good, even if I keep power pressed for 20 seconds or more, it's like the power button is constantly pressed. I also can enter fastboot by only holding volume down while it loops, which is unusual...
Thanks!

I managed to flash it through EDL.
However, it seems like the piece that holds flex cable and side buttons is damaged. It's like the power button is always pressed (making the phone reboot over and over) or non-functional at all.
I'll change this piece and see if works properly.
Hello there! During my holidays I accidentally slipped into a swimming pool while holding my Mi 9 Lite on my hand :crying: . The device was merged into the water for no more than 2-3 secs but seemed enough to do some damage (apparently). At first the device was in a loop booting again and again in the mi recovery mode, i gave some time to dry it and suck the water off the phone. At the end of that day i tried to turn it on but after the mi logo and the vibration the mi logo seemed to fade out and the screen turned off. I got into the mi recovery mode, did wipe all data, but still the logo died after a few seconds i tried to turn the phone off... I am trying to use fastboot and miflash in order to flash again the stock rom, but no mater what i did, the device is not recognised by the pc. I did manual install the drivers, used adb, set the device as portable device, but still im not able to connect the phone in order to proceed with the flash... Is there a way to fix it because the device seems to work and respond properly (buttons on the recovery menu, the image of the fastboot looks perfect etc..), or it is permanently damaged ?

I don't think water damage is covered under the warranty. You could try to point a torch down the USB-C port and see if you see any obvious corrosion blocking the port. If you see some then you could use a toothbrush and some isopropyl alcohol to carefully clean out the port. If that doesn't resolve it then it is likely that the water has gone through your phone and has caused damage to components.
I have a Pixel 4a that I dropped from coffee-table height onto a wooden floor. The phone landed on an edge and broke the internal screen. The outer glass is undamaged.
Initially there were rainbow lines all over the screen, but after abandoning it for a few days, now nothing shows up on the screen at all. Charged it overnight. Nothing. It does make the device a little warm, though. Powering it on produces no signs of life.
When I took it to uBreakiFix they checked for a minute and said since it doesn't respond to charging (no vibration) and doesn't seem to "power on", it probably has a dead motherboard as well.
However, when connecting it to a Windows laptop, it is reported as "Pixel 4a(5g)" in Settings>Devices, and an "MTP device" shows up in Device Manager.
Since I did not have File-Transfer as the default option for USB, and because ADB was not enabled prior to it breaking, I am left with no real way to test this device.
I also put another SIM into the phone and tried calling it, but it goes to voicemail.
Is this phone dead and ready for recycle-grave? Or is there any hope? Help is much appreciated!
Pull it apart. May have loose connectors.
See what visible damage is there.
No visible damage doesn't mean your in the clear but it's a start. Inspect the battery for swelling, a failed Li.
If it starts responding when you use a pencil eraser to gently push and flex the mobo different ways, push on the BGA chipsets, that's clear sign of a mobo solder fracture or broken trace. You can also try this with the phone together by putting pressure on the case at various points... don't go too nuts with it though.

you can do some things booting twrp (fastboot boot twrp.img) for your pixle 4a provided your phone bootloader is unlocked (fastboot flashing unlock vol down once then power to unlock without screen is the command). i can't remember if it wipes the phone or not. adb devices should see the phone once you boot up twrp. you should also be able to access the phone like a usb drive as well. if you are trying to pull data off it. make sure you have the latest google usb drivers installed from their website https://developer.android.com/studio/run/win-usb
this should give you some sort of start. to see if it even is responsive.
