Title explains all. I'm in a tight bind with money too..
I want to believe I can just reflash stock via odin and it will come back. Or is there something else I can do to make this work?
It sense touch 10% of the time, but it's never enough to unlock my phone or do anything with it.
Edit: the new screen worked perfectly before I did the operation. Don't know what went wrong. I didn't scratch or bend anything to my knowledge. The process took about 10 minutes and went really smooth.

Hello, I repair cellphones for a living. And it depends on a lot of things. My guesses are three things. From most likely to least likely.
1. You said that everything was working fine before you changed ROMS, it could be an incompatibly issue between the screen and the software. A lot of aftermarket screens are mostly compatible with stock, a lot have compatibility with custom ROM. It could be an issue solely on the software and not related to the screen.
2. There isn't a solid connection on the LCD connector, that usually happens with during installation, sometimes if the device is set down hard or dropped knocking the connection loose.
3. It's a defective screen. It happens sometimes. It's not uncommon for a screen to appear fine but after a few hours it acts up. It could have just been a coincidence that you noticed or went defective when you flashed (not saying flashing is responsible for this scenario).
Flash back to stock and then you'll have a great chance of to see which out of the 3 are responsible. Cheers.
I repair iphones, android devices, laptops, ect.

There are only 2 flex cables on the S5 LCD. Make sure the primary (top flex) is seated correctly, then the easiest thing to check before taking the screen back off is the flex under the battery cover. You will see a little screw near the lower right of the battery with a little cover. Pull up that cover while the battery is out and make sure that cable is seated correctly. If both flex cables are seated correctly then it can only be 1 of 2 things IMHO, the screen you purchased is defective or you bent some pins on the mobo where the flex cables attach. I don't think it's a rom issue.
As you can see in thread, phone just dead. Dunno what happened. I bought it an year ago. I've tried to connect it to computer and it was visible as QHSUSB bulk but now i can't see it there. It doesn't react for turning on. I can't get into download mode, recovery mode. Very long time ago i flashed Android MM from xda and it was working good. It had ~50% of battery when died. I've tried to put off battery and then connect to pc but still nothing happen. It has broken screen (was working good) but i've done it in September 2016 so. I can connect it to Linux but i think it won't help too. Any fixes? I think they won't take It at warranty because of screen. Phone looks like dead for ages :<. @edit IT'S NOT DEAD! I've disconnected something from battery this longer one and when i click power i can hear "something" in the phone. And it gets heater so looks like processor is working. But it's still not visible in the device manager.
edit2
i know emmc pinouts.
While I was using the phone, with battery at 66%, the exact same thing happened to mine. I'm sick of it. Time for a new phone.
(Had the rooted V15c image on it, no broken screen, only the camera issue - should someone care)
Same problem here, what is happening . My phone was approximately 80-90% and it suddenly turned off and I can't turn it on ..
bump
Phone went black with warning
The same just happened to mine. It was fully charged and I was using it and then the screen went black. There are no lights when I plug it in, no vibration after pressing and holding the power button. Nothing
I've connected it to my pc and a driver installed, I think the same one as a post above (QHSUSB) but still the phone doesn't respond in any way.
It's the European H955 on official MM 6.0.1 no root or mods and is out of the one year warranty yet was in excellent condition. Does this mean the phone is for scrap and nothing can be done?
Hi, I found a solution to repair the phone in this state. I start by telling you a story, a long time ago I had an HP laptop. video card was detachment from motherboard, and to a stick again we used a method called reflowing. I thought that the phone has the same problem, however we have nothing to lose so I opened the phone I took out the motherboard and started to warm up each chip using a hot air blower. I mounted the phone back and now works like new. I apologize for my bad English I am from Romania.

Any one tried this method and succeeded may please inform on this forum
My phone crashed, would reload to lock screen then restart and finally would not start at all. Before this the rear camera stopped working.
I had reset, flashed a new Rom and replaced the Camera which didn't solve the issue.
After the phone died I tried reflowing though I had no heat gun so I just used the oven. 200c for 7 minutes after disassembly.
That was about 8 hours ago and I am typing on my phone.the Camera is also working.
I will post if it stops again. I did it as the phone was dead and I had nothing to lose.
I have the same problem, and I am interested in getting a heat gun for this purpose. What specific parts of the phone did you reflow/heat? (in terms of the chips, or the entire board.)
Thanks in advance.

What part of the phone did you reheat exactly? The whole phone? or did you take all the plastic out?

Also be sure to take off the rubber part on the back. The purpose is to remelt the solder.l, so only board and nothing else.
To disassemble there are some videos on YouTube. Remove your sim card before taking off the backing
Remember this is a last resort, you could end up with a completely dead chip.

Thanks for the information. Is there a specific way you have to remove the shields, or do I use a soldering iron to get it off? (And if so, does it do any good to solder them back on?)

Did it 395 degrees Fahrenheit (201.66 Celsius) for 7 minutes, I preheated the oven. The camera and everything now works fine.

You shouldn't have to use a soldering iron to take anything off. At least not as far as I am aware of.
I should note that as of this morning my phone when blank and will no longer turn on. I will try reflowing at a higher temperature as some solder may need a higher heat but I am not optimistic that this is a permanent fix.
Hey everyone !
First try to connect it in emergency mode to the computer in order to flash with LG UP. If you cannot boot into emergency mode but the device appers on your computer ( and PC is unable to connext into GF2) maybe you could burn your motherboard.
I burn one 7 months ago with my device resting on my pocket so its a common problem for this device (as official support told me so its full covered by guarantee )
Hope you can solve soon !!!
My Asus Zenfone 5z suddenly stopped fast charging i know its not the charger thats the problem, ive used it on several different phones and it still works. Now comes another problem, when i charge my phone and restart it while plugged in the charging symbol doesnt appear but i know its charging but slowly via ampere app. I need to unplug then plug it again then it shows the charging symbol. My PC's and Laptops cant detect the phone but charges it. I have the bootloadeer unlocked, but when i charge my phone powered off it pops up every few seconds and the LED indicator doesnt light up. I tampered with something then it fast charges all of a sudden, i even moved the phone around to ensure that the charger isnt faulty. Then when i went to go and charge my phone is slowly charges up again.
Any help? Do i just go to a technician? its harder because its lockdown where im from. Is it my charging pin thats faulty??
Maybe cleaning it can help, use isopropyl alcohol and a tooth brush or cotton swabs.

I echo what @XDHx86 has stated. At times, your charging port can be clogged up with dirt, lint, dust, etc... Cleaning it might resolve the issue. However, be sure not to use anything but isopropyl alcohol, preferably 70%+ solution.
Could be a charger port (PBC) failure if cleaning doesn't help.
Could also be a battery failure. Check for any signs of battery swelling.
Unlikely it's software.

no battery swelling, but i might go to a technician and see if they find a problem. As for now im trying everything before going. I did something, forgot what it was but it fast charged then i wiggled my charger around to see if it stops but it didn't. Tried plugging again and again but after a few hours it didn't fast charge again. Anyways what's a PBC failure?????
The charging port is mounted on a seperate printed circuit board in many phones.

You replace the port PCB. The port PCB can effect other seemingly unrelated systems when it fails depending on the manufacturer.
What warning? It may be a firmware or hardware issue. Normally the firmware doesn't go corrupt for no reason.
Possible mobo failure.
There's also the possibility of a rootkit infection.
If running on Android 8 this becomes more likely and if so it may need to be reflashed to purge it.
Is there any other kinds of unusual behavior when running?
You need a tech who is very familiar with this make.

im running on Android 10. I'm talking about the warning when you power on your phone(image attached) Yes, i have some unusual behavior that's been running for the past few days such as: When i restart my phone when plugged in the LED light turns off when its powered off then turn on during the booting screen, then it will completely off once the phone is open BUT my battery percentage isn't going down. I still see it charging via ampere app. The charging symbol also doesnt show(i need to unplug then plug again for it to show) The phone still charges but very very slow.

I'm no expert on this, but is that a normal warning if you unlock the boot loader?
I'm not advising you to lock it as that may cause other issues but doesn't having unlock increase security risks?
In any event if it does have a rootkit* a factory reset should purge it. If it has custom rom, I have zero experience with them.
I don't like using factory reset as it's best to find the root cause instead. In your case it may not help at all if the root cause is hardware. You need to observe the symptoms and use the process of elimination.
This is one of the reasons I run a stock Android, in some respects it simplifies troubleshooting.
* be careful with all downloads especially side loaded apps. Playstore downloads aren't without risk though.
Email downloads are high risk; keep it all in the cloud whenever possible.
Check the download folder regularly for odd behavior and unauthorized downloads.

You're welcome. Sorry I couldn't help you more.
I be very careful about locking the boot loader.
Make sure you know the full implications before doing so.
You might consider flashing it to it's stock rom especially since the boot loader was unlocked when you got it.
Make sure it's functional enough to take a flash though, last thing you need now is to brick it.
If it's a hardware issue this should be corrected first.

I've tried factory resetting 2 times to no avail. It's a normal warning sign, its part of the booting process. But if i power off my device then charge it keep popping up every few seconds. Would a custom rom fix this? or do i just go to a technician now? Also for some reason only Type A to C chargers work. Ive tried my sibling's charger that's Type C to C and it doesn't work, but Type A to C works for them. Also my phone charges on my PC but it doesn't detect it despite having my phone on file transfer mode. I'm trying everything as it's hard to go to a technician especially during covid

Yeah, bricking it would be a bummer. I'm still researching on bootloaders and custom Roms in general. Tips on it would be great tho. And no need to be sorry. And I saw this reply late, I've replied to your previous comment.

The unlocked boot loader is suspicious.
Like I said if it's hardware is stable enough to do a reflash I would. Go with the OEM rom it originally came with for now so you have a known good rom loaded... it will simplify troubleshooting.
Error on the conservative side.
Letting a good experienced tech look it over is the safest route.
Finding one may be difficult. One that's does rooting may be more helpful.
On the PC try accessing it in drive management, try the rescan drives command.
The PC not detecting it maybe a driver issue.
In hardware management try updating or rolling back the driver. Try another port.
Reboot...
Look at Event Viewer for error messages after trying to connect the device.
If it's not the PC it maybe the phone's port PCB has failed.
Inspect the phone port carefully with a good light source and magnification. Look for signs of damage, corrosion or debris.
Try gently cleaning as mentioned with anhydrous (99%) isopropyl alcohol and a soft bristle toothbrush. Allow to dry in a low humidity room before using. Isopropyl alcohol is hygroscopic so it will grab moisture out of the air to some extant plus the cooling tend to do so all well.
A blower bulb or fan helps speed drying.

If don't have the skillset it be probably the best plan. Ask about experience and pricing upfront.
If you can see the techs working and using ESD mats/wrist straps that's a good sign.

it looks like this when i restart it by the way. Mind you the Charger is secured. And at the end i unplugged then plugged it again then it charges. I've tried using the phone while charging to see if it stops charging but it doesn't, so i ruled the charger out of the problem. Thanks again.

You shouldn't need power it off to recharge.
So it won't charge unless powered off?
To give some context, my S10e (Verizon SM-G970U) decided to boot loop out of nowhere. Since this happened, I have factory reset the phone, no success. I brought it to a local repair shop who said they couldn't fix it. Now I have flashed the phone with Odin and despite the phone being flashed it STILL is boot looping. At this point, I'm assuming something went wrong with the hardware but I don't even know where to start with that. If anyone has any suggestions I would greatly appreciate them.

If it is a hardware issue (which sounds likely), there's an old electronics trick you might try: Power it off, put it in the refridgerator awhile, take it back out and power it on. This has work'd for me with stereo components, for example, as well as a phone. It once revived a hard disk drive long enough for me to capture important data. Oh, but the phone this has brought back for me, an S10e BTW, works only while still cold and has issues with charging while its temperature is low. Still may be worth a try.

Wow, I just did this and to my surprise it worked! Prior to this, I wasn't able to get past the Google sign in page on start up (on good attempts) but now I was able to get it all the way to the homescreen and even install some apps before my battery died. Any idea of what this could mean for the actual hardware? I.e. this means the battery needs to be replaced etc

Great; glad it work'd. Did you attempt to charge it while it was working? Mine actually took charging after warming up only a short time, once. Got it back all the way to 100% charged. But then it quit with dead black screen, and now revives only for a minute or two.
In the old days of individual transistors, we used to turn on a non-working electronic device and blast a shot of freeze spray on various components until the device started working; even with IC (integrated circuit) chips that have lots of transistors. This way, we knew which part needed replacement. But with today's phones, you replace the entire circuit board because the soldering is done by machines; it's too finely detail'd to replace one chip.

I haven't tried charging the phone when it's on. Only when it's off and has returned to room temperature. Seems to me that about an hour in the fridge equals about 5 minutes of screen on time until the phone heats up again.
As for the internal component's you bring up a good point. Even if I were to determine what is causing the issue, I don't have the will/technical know how to buy the parts and do it myself. Outside of just replacing everything, in which I'd just buy a new phone haha.

Hi all. I have a 2016 Sony Xperia XZ running on Android 8.0 Oreo. My battery got swollen and I try to replace it with newer battery.
The process went normally, but when I try to boot the device, the phone just shutdown and after its reboot, I got a message said "your device is corrupted and cannot be trusted".
It's weird, it never happened before. And when I shut off the phone, it didn't even charge. My question is;
1.Did I messed up the battery connector, I try using my old battery(swollen, but still has good health), but it got the same issue, and it wouldn't charge.
2.If I messed up the battery connector, for sure it wouldn't boot up, but the phone boots, but after 1 second it shut off.
3.Does sub-par BMS chip can cause the motherboard goes haywire? Or it just a firmware/software issues?
4.I use a Japan secondhand set(SOV34 KDDI AU), the bootloader is can't be unlock, but I already enable USB debugging on developer option, can I use any firmware flasher on Windows?
Try a factory reset.
You may have damaged the display and/or mobo assuming it has power.
The brick alone doesn't supply enough current to boot.

The firmware shouldn't be corrupted. It rarely happens. If you flash go with a stock rom although with an unlocked bootloader you have more flexibility. Try to rule out a hardware issue first.
A factory reset wouldn't be the first option I would until I was confident it wasn't a hardware caused failure. Flashing be my last resort. I never had to flash any of my Androids in over a decade due to corruption. Usually it's the user partition that gets corrupted or more likely a 3rd party app screws it up. A factory reset would set back to its default settings*.
The bootloader being unlocked plus running on Android 8 make it much more susceptible to rootkits and malware... bare that in mind. Android 9 is a more secure OS. 10 is sort of a pain and uses more resources.
*Android 8 and lower are suspectable to partition worming rootkits like Xhelper. If infected with that it can be purged without a reflash now, I believe. If present it would need to be addressed though...

The firmware shouldn't be corrupted. It rarely happens. If you flash go with a stock rom although with an unlocked bootloader you have more flexibility. Try to rule out a hardware issue first.
A factory reset wouldn't be the first option I would until I was confident it wasn't a hardware caused failure. Flashing be my last resort. I never had to flash any of my Androids in over a decade due to corruption. Usually it's the user partition that gets corrupted or more likely a 3rd party app screws it up.

I saw lots of Pixel and few Sony, LG and Moto also had that issue. In terms of Sony, I did saw Xperia XZ2 did had that issues.
But my phone can turn on, it went to the lockscreen and less than second it shut off. I'm quite scared if its a hardware issue, it couldn't charge, but the battery connection looks okay to me. Does low quality BMS chip can cause some haywire to the motherboard?
My bootloader unlock status is no, because it's rare to found a Japan import set that can unlock its bootloader.

Is the battery known to be good? What voltage is it showing? That's not a load test though.
I know it's new, but...
A new battery should have somewhere between a 30-70% charge on it when recieved. So if good it should have enough to boot it even if not charged. If not charging and especially if the power state is unknown flashing firmware is unwise.
If there's no indication of charging it could be anything from the outlet, brick, cable, port, connector(s), battery or mobo. The SOC is a BGA chipset and can be damaged by excessive board flexing as can other chipsets.
Can you get into the recovery menu?

I've read review of the seller of that battery, mostly positive, and I bought my past battery from the same seller and it didn't had any issues other than swollen after 1 year of usage. The battery arrived I think at 40%.
I've read on some thread that when Android phones got corrupted like mine, it can't be charge at its off state, unless if it's enter flashmode, then it can be charge. But I couldn't remember what thread that was, it might be XZ2 thread. On Pixel and OnePlus thread that I found also said the same thing.
Can I know how to enter recovery mode for Sony Xperia XZ? For the time being I unable to access to any Windows PC, so I can't try charging my phone via flashmode.

I don't know if that's true or not. Try some Goggle searches. It's a handful.
It shouldn't have gone corrupted unless there was physical damage as flash memory retains its data for many years without power.
ESD damage is also a possibility. If you can't bring up recovery it's essentially bricked... I think.
The battery seems isolated from the mobo. Check the C port pcb for damage. The display is in harm's way. I had a battery fail on my N10+, because of the case I didn't notice the bulging rear cover. I was very lucky the display wasn't damaged.
Maybe someone else here has a better plan.

Oh, I'm sorry, I forgot to mention that my older sister phone, Sony Xperia X Performance, also use Snapdragon 820 and Android 8.0 Oreo also had that same issue as mine once when I swap a new battery, but it happened once and now that phone just run normally without any issues.
It's totally weird why I saw lots of Pixel device got the same issue as mine, and most of it said they never open their phone and never even disturb its bootloader or some sort.
I think the last resort is for me to use Sony PC Companion to repair my phone, or flash the whole firmware using Flashtool. If it still had that issue, it must be I messed up the board or something.
Thanks so much for your help, I really appreciate it a lot.

You're welcome.
If it's a known issue than it maybe exactly that.
Sorry I couldn't be of more help to you.

Oh not at all, I'm totally glad that someone reply my post. I'd just found the thread that I mentioned, it's from Sony Xperia 1 II thread. This person had the similiar issue as mine. Hopefully it's a software issue consider their phone did successful to boots up.
1. Phone got corrupt.
2. Battery is low and can't charge when it's off.
3. Only charge if it's in flashmode.
Bootloop - Your Device is Corrupt
Yesterday I flash SEA firmwear to Xperia 1 ii via Flasher which result to constant boot loop with error message "Your device is corrupt. It can't be trusted and will not boot" I have attempted to repair the phone via Xperia Companion, however...
forum.xda-developers.com
Sometimes it takes a while to get replies especially with older phones.
Yeah I found this. Hope that gets it for you.
Try Google searches like: "Sony Xperia XZ, your device is corrupted and cannot be trusted"
Google searches are the easiest and probably the best way to search the XDA forum
The Google web crawlers never sleep... they don't find everything though even with precise key words. You may dig up some more useful information as it is out there by now.
Cross platforming works many times; it doesn't need to be that exact Sony model. Many issues are long standing and are found on to several models even years apart. Use whatever comes in handy...
Woah, thanks a bunch for posting link for that thread, I keep Googling it but never found that thread on Sony's forum yet.
I did found some Xperia XZ2 that had the same issue as mine. I totally curious what cause the software to be corrupt like that, bad apps maybe? I did uses a few cracked apps that I sideload the APK, maybe that one of the reason.

Bad apps can screw up the user partition data and sometimes cause a boot loop. They normally can't corrupt the system partition though... they shouldn't be able to.
There's the little monster xhelper. Android 8 and lower are vulnerable to it. Always scan any side loaded apps first with Virustotal. A seemingly good app could also latter download its payload.
If any doubt exists do not install it.
