Xperia Z2 - bootloop after factory reset - Xperia Z2 Q&A, Help & Troubleshooting

So, I have my Sony Xperia Z2 from a while now. I recently broke the screen, so I had to get a replacement in 3rd party repair shop. They've managed to repair it l, although I discovered that the battery is draining faster than usual. So, I performed a factory reset via GUI, it went alright, but it took longer time than I expected. Suddenly the phone was freezing, especially during islnstalling new apps from Play Store. I've had enough of it and I performed a factory reset once again, with around 40% of battery. It took an enormous time for my phone to wipe the data. From that moment the phone is stuck on the waves animation. When I'll hold volume down key in the startup its booting into the system with a notification "Android is starting... Optimizing apps X out of 177." After reaching the value, it changes the communicate to "Starting up", freezes and restarts again into waves. I should mention that the USB port is broken, I can get the connection, but after twisting the cable. What should I do? Is it bricked completely? Can I take it to the same shop and let them do the job?

Ifyou can connect to the pc try to flash via flashtool

[Q] Device Freezing / Dying?

Has anyone experienced their phone freezing/locking up? I'm not talking about lagging/freezing applications, but the whole phone actually locking up.
My phone seems to be freezing up about twice a week and has been for the last 3 weeks. Each time it has been when the device was in my pocket or on charge at night (and subsequently the alarm does not go off).
When the device is frozen like this, it has no indications of even having power.The power button will not turn the phone off, on, or wake the device. Plugging the phone into power doesn't even turn the orange/green charging lights on, nor play the tone for when power is connected.
I physically have to remove the battery for a few seconds from the phone and re-insert before the phone will start up. I have even performed a hard reset on this device.
Has anyone else experienced anything like this? I'm thinking that it might be a hardware fault, or at a really wild guess maybe the HTC Attentive App.
I'm having no problems with crashing or freezing!
I have actually found the device to be very stable, a lot nicer cleaner and stable than my previous device (Sony Ericsson Xperia X10).
Had exactly that problem a couple of times already. The only solution is to pull the battery out.
Still - better than an iPhone crash which requires you to plug it back into the PC before it will work again.
I had a similar situation:
I was making an international call (card service), when finished i heared the card IVR prompt if i need to make another call. I wanted to hang up but the screen was black adn dead. power button did not bring into life and i was keep on hearing the active call. had to take the battery out to kill this situation.
typically windows behaviour
Thought I had narrowed this down to the HTC attentive app, but alas the phone froze again this morning after hitting snooze 3 or 4 times. Oddly enough, the power button would turn the screen on and off, but the lock screen wouldn't show, nor could anything be moved or controlled on the screen (live tiles were still animated though). Battery pull again.
Yeah, typical windows behavior. No where near as bad as Windows Mobile which I came from though
I have the same issue. Can be in the middle of a call or anything. Had it reboot once while on charge too. Did you just remove the attentive app? Would it be worth trying a Hard Reset if that wipes the device. If so how easy is it to put your old Apps back on. Or do I need to write a list and search manually.
I did a hard reset and just didn't install the app again.
"When you buy or download apps from the Zune PC client, those apps are automatically redownloaded to the phone when you reset the device and login with your Windows Live ID again. When you download apps from the phone itself, you have to go to the Marketplace again to manually find and redownload the apps you want."

[Q] Big problem

My phone displays the icon in the attached picture (when i shut it down).
It does not start-up, only from the recovery mode (with restart option).
The battery life dropped from 3 days to 12hours suddenly (once with this problem)
I notice that this problem appear from the day when i found my phone in the pocket unlocked, and a lot of app's were opened.
A messege "MTP connected" appears sometimes (without connect something)...
I made factory reset and a restore from a time when it was ok, and nothing.
What could be the problem?
Known issue. Clean the USB port and try a factory reset. If it doesn't work change the battery or bring it to a service center.
I tried with a new battery and same problem, i clean the usb port on the phone and nothing.... i mention that are some moments when it's working fine... (in most of times when the battery is on low level).

Click to expand...
Click to collapse
Looks like it got hot and you have a hardware problem that you can't do anything about except for sending it in for servicing
Problem resolved, it was the electronic board from the bottom of the phone (the one with usb in and mic) and some tranzistors... very few services repairs in detail this phone, lot of services told me that i need to replace all motherboard..
But the important thing is that the phone runs smoothly

Help LG G5 VS980 not booting properly problem

Hi, I was using my LG G5 while plugged in, all of a sudden it acts weird, app crashes, lags and a few part of the screen goes black for a short moment. It then shuts down and restart itself, but stuck on some sort of a bootloop (it passes the logo screen but then the LCD goes black and keeps turning itself on and off repeatedly with nothing in it, also the LED light is showing blue)
I took off the battery, put it back in, and turned it on. But it ended up the same. So then I went to the system recovery menu. The recovery menu works just fine. However I've tried using its safe mode, wipe cache, factory data reset, continue power up, and none of them seems to work. It just stuck on that bootloop.
Since I was getting desperate, I left the phone in the bootlooping state for awhile.. at some point it started normally and goes to the choose your language menu (because of the factory reset I guess). I was so relieved, until it restarts itself again.
I've tried replacing the battery with a new one, also doesn't work. There is no LG service center in my city, and I have no warranty whatsoever over this phone because I bought it online. I couldn't find anyone with the same problem.
Here's a video showing you the problem:

Help guys.. What should I do and how to fix this?

Amazfit pace is stuck

Hello,
Just bought a brand new pace watch
Fully charged it before first use, start it up, and got it frizen on the main screen with the time frizen since then. Nothing responds:not the button and not the touch screen.
The pc doesn't recognize it or charge it as well.
Any ideas?
Thanks!!
Any ideas guys?
Pressing the button for around 10s may reboot the watch. If still keeps freezing you can do a factory reset with your PC:
Code:
adb reboot wipe
Or as it's a new device just claim for warranty and a replacement.

Need help with Bootloop on Xperia XZ1 (info inside)

Hello.
First of I'm a fan of this forum for a couple of years now but never had a chance to have an account until now (Still a total newbie), anyhow I tried to fix it myself for weeks now searching and looking for almost everything I can both Google and here but no avail. desperate as I'm now I decided to start this thread.
My phone is Sony Xperia XZ1 G8342, the problem is boot looping as I stated the possible reason I think it's because of low internal storage (64GB) I used around 90%, and yes I did clean up the cache from time to time but its keep building up back again. I have had experience with this problem before (only once) around 5 months back it kept looping so I force shut down > turn it on again repeat this process for the whole morning and suddenly it's back to normal.
How it started.
I charge the phone and Google play probably automatically updates all the apps, which is really dumb of me to turn this function on, then it freezes and starts restarting.
My goal.
I know people will tell me just be done with it and re-flashing or use a Sony PC companion. but in this phone, there's a data that hold dear to me, I know this sounds stupid in some aspects and yes it's totally my fault for not backing up some of these data and still relying on a 5-year-old phone. But I hope to fix it without losing all of these data and at least be able to access it for backing up.
More info on my phones.
None root.
The phone can turn it on normally but it's will restart itself once it reaches the Xperia logo (FYI: booting > Sony logo > Xperia logo)
When connecting to the PC and holding volume up the led light will turn blue (I'm not sure if this is Fastboot mode or something else) PC will detect as Android devices when checked on Device Manager.
When holding volume down + power then keep holding volume down the phone will vibrate after reaching the Xperia logo but still to no avail.
Sim card and Sd card are removed, same result.
The battery is replaced about 2 months ago.
All other parts except the battery are original.
It can charge normally.
USB debug mode is off. (very unfortunate)
I don't think XZ1 has recovery mode which really sucks since older models have it and newer ones also have it.
Any solution or suggestion is very welcome here, I'm not a native speaker my apologies for that.
I don't want to list what I have done so far because the way I have tried might not be correct, I might miss some tiny details or maybe I could try it again if you guys suggest.
Regards.
