I have a Sprint TP2 which I have SIM, Security, and CID Unlocked (using Olipro's wonderful unlocker). I also have Sprint's GSM radio flashed. The phone has worked perfectly with my T-Mobile SIM card for the past 4 months, but suddenly it decided to break! Just last week, suddenly the phone was stuck on the HTC loading screen but luckily performing a hard reset fixed it. However today, the phone wouldn't turn on at all. I tried hard resetting again, but the phone showed no response (the screen was completely dark). I also tried a soft reset, but the phone was completely unresponsive. I can't even get it to display the bootloader screen! No matter what I do, the phone remains on a black screen. When I plug it into the computer, the orange light turns on but no matter what buttons I press (hard reset, soft reset, etc) the phone's screen remains black. I have gotten a brand new battery and put it in the phone, but this does nothing.
I've noticed that the phone emits a faint buzzing sound when the battery is inserted.
Is there anything I can do to fix this?
dude im think you are fcked, try charge the battery first. and see if the light comes greens thats mean that the phone at least have something working. after that try to get it on the boot menu to do a usb rom update, if you have some skills open the phone and clean it inside and de ram memory (next to the mini sd) any way wait for the gurus of the forum to have a better info about what to do and good luck

guess/shot in the dark: if you plug it into the PC it doesn't try to load some new USB drivers by any chance, does it?
As last chance
Try CMonex thing first, then if phone is out of warranty and definetly seems to be dead as last chance i would try to dismount motherboard and remove all the shielding covers to expose electronics. Take care to ground yourself to protect board from electrostatic discharge.
First inspect it with a glass lens to see if there's some kind of phisical damage or if all seems to be okay.
Then thoroughly heat it up with a hairdryer (set at max heat and max speed, very close to the mobo) paying attention not to blow any plastic or flex cables. The goal is to eventually restore fake solderings that may have occurred due to age or shocks. You have to be very patient and careful to heat it very well but not too much: there's no need to see tin melt, this in fact would be dangerous, just till it turns a bit shiny, some experience and understanding of electronics helps.
I tried this method a couple of times with dead phones and sometimes worked.
Hope you can work it out.

I have a fuze that took a (pretty light) drop, and now it won't power on. When it's plugged in it actually powers itself on, without pressing anything, but all it does is power up to the white screen where it says ATT world phone, then it powers off, and keeps doing it over and over again. EDIT: I can get into the bootloader screen, but a soft reset from there creates same looping problem
This actually happened before, but i changed the battery and it worked again. Now i must think it's something in the phone that is doing it. It's under warranty from ATT, so i could probably exchange it, but i would lose some important info in the phone, and i worry they will see my custom ROM etc and may try to void my warranty and charge me for the replacement.
Any help appreciated!
Hi,
Last night when I turn off the cellphone appears a screen with four colors (red green blue and white) ... not going into windows mobile ...I turn it off and turn switch on and press the reset and nothing!
And as I left the tricolor screen i got no battery, so when I put my mobile charging it always switched on and off the screen by himself becoming the tricolor screen.
Can someone help me?
Thanks
Hopefully you backed up everything. At that point, I would do a hard reset, which restores it back to the factory settings and deletes everything off of it. If you're comfortable doing that, you have to find the instructions to hard reset your handset.
Mine was Sprint's HTC Touch Pro 2, so for me, I held down the TALK, END, and POWER buttons until the screen came up and I just followed the instructions. If that doesn't work, let me know what brand you have and I can look up how to do it on yours. Good luck and let me know if this works for you.
Hard reset probably won't work in this case, although it certainly doesn't hurt to try.
Looping to bootloader (the tri-color screen), based on previous threads I've read, usually indicates there is something wrong with the ROM itself, which may require the stock ROM to be flashed.
Might also be a hardware failure.

At this moment I cant do anything with the mobile because it has no battery to try to do something, because when I switch to load it turns the screen tricolor on and off right after!
And if I ordered another battery it takes longer than 30 days
I think the solution is to send for repair to HTC because he's still under warranty!
But thanks for help
Flash stock ROM and see if it flashes. Usually they flash. If it doesnt, then send it to repair.
Make sure you use the wall charger, and don't try to charge via USB. The USB cable won't charge the battery if its discharged too far.
If you charge from the wall charger overnight, it still won't power on?
Hi:
I have a HTC sensation 4G. I really like the phone. However, about 3-4 months ago, my phone suddenly switched off. When I restarted my phone, it got stuck on the HTC logo and wouldn't go further and switch off. It would start again, show the white screen with the HTC logo and switch on again. It wouldn't go any further and kept doing so in a loop. I thought there could be 2 possible reasons for the same: 1.) software issue or 2.) Hardware issue. I was pretty sure it was not a software issue as I had not made any changes in the software. I took it to a HTC repair center. The repair charges they were asking were freakingly high (300$!!). I didn't get it repaired from them. However, they gave me the exact reason of the problem. They said that it was a hardware issue and often happens with the phones when battery of the phone is removed while the phone is running. If this is done multiple times, such an issue can arise. I had done it multiple times before the phone had stopped working. I then got the phone repaired from another shop paying a third of the price. He didn't give any guarantee if the phone works. But the phone started working after the repair.
Very recently though, I was using my camera and as soon as the flash came on, the flash light got stuck. The phone was, however, working. But I couldn't get the flash to switch off. So I thought of restarting my phone. The phone switched off and when it turned on, it had the same problem. It is stuck in a loop on the HTC logo screen. I think this could be a software problem. What can i do to repair it?
Another thing I want to mention is that I am unable to go even in the recovery. When I try to go in to the recovery, it switches off and shows the HTC screen again. On one occasion when I tried to go into recovery from the boot screen, it showed a message that the battery voltage is low, please change the battery immediately. So i thought it is a battery problem and I looked up on the internet to find a solution. Somewhere I read that sometimes the gold plated contact points on the battery get scratched and corrosion happens. One solution was to clean the corrosion and try again. I did but didn't work. Also, when I try to charge the phone (because the battery voltage is low), even if the phone is switched off, its starts up again automatically without pressing the power button. Then it keeps going in the loop.
I don't know what the problem exactly is. Do i need to change the battery? I am running official HTC ICS ROM. Please help me with a solution.
It will be of great help. Thank you!!

Hello!
I recently tried to replace my LCD/Digitizer on my S6 edge SM-G925V. Everything went well...at least I thought. The display works great! However, I believe I have either a battery issue or a OS issue.
After I installed the new screen, I booted the phone up. It loaded up fine. I went to check to make sure every feature worked. I was playing music to test the speaker and the phone just restarted on its own. I found that to be odd, and so I tried again. Same thing. This is just a couple minutes into it turning on by the way. Sometimes it would take longer to restart than others, but it was generally in the same time frame. I did try other apps to see if maybe the music app was causing it to have issues. The phone would restart randomly regardless of what I was doing.
I first thought that maybe the battery wasn't charged up enough. I charged it some, but was still getting the same issue. I then went to try and boot into safe mode. Still the same issue was there. I tried resetting the phone, master resetting the phone, and also wiping the partition. The phone now boots to the Samsung screen, then goes to the Verizon screen and then reboots in a endless cycle.
So...it was booting correctly, but randomly restarting. NOW, it's not getting past the Verizon screen and rebooting.
I tried using Odin and resetting it using the latest software update. It would pass just fine. The phone would reboot then go to "Installing Updates". It would get to 32% then say "Erasing". It would reboot back to the Samsung screen and start the endless boot process again.
The one thing that Intrigued me and led me to trying to use Odin was that when I would boot to the Downloader screen (The blue screen where you have to press up on the volume button to continue or down to cancel) the phone would never restart on that screen. I figured if it was a battery issue then it would restart regardless of what screen I was on.
But, I noticed something after all of this. The LED stays light up blue when the phone is powered off. The LED lights work correctly when the phone is on (Red when charging, changing from blue to green in a wave like pattern when turning on).
That kind of made me rethink the problem, and go back to it being a battery?
So, this is where I stand now. The phone would boot up, but randomly restart. I thought the OS may of been corrupted or something went wrong during the replacement of the screen so i tried resetting it, etc. Now, it the phone is just stuck in a endless loop. I noticed the LED lights up blue while the phone is turned off, so it has led me back to thinking it's a battery issue.
Lastly,
I don't believe I messed anything up when removing the battery. I was very gentle. I was watching a YouTube video that pointed out that thier technician poked the battery in the video, and they kept it there so we could learn from their mistake. Their battery leaked out a little and showed some residue on the black part of the piece it is mounted in. I never seen in residue or anything like that when I did mine.
I also unplugged the battery first before unplugged any of the other ribbons connected to the motherboard.
I am new to repair screens and I wanted to try on some of my old phones to get practice. Although this issue is frustrating, it is giving me a loads of knowledge on issues. It would be greatly appreciated if anyone could help me out with this. I'm not sure where else to go from here. I do have a battery ordered, but probably will not get here til sometime next week.
Thank you everyone for taking the time to read this long post!
Try replacing the battery. Make sure all grounding pathways and connectors are properly connected. Sometimes they may use unconventional pathways like the frame or a screw.
Impacts that can break the screen can cause high enough G loading to internally damage chipsets, fracture solder bonds (including hidden BGA ones) and damage internal mobo traces.
The display and mobo when out of circuit are suspectable to ESD damage. Full ESD protocols and procedures should be followed. Even though many techs don't do this doesn't mean they don't damage hardware. It may take weeks or even years to manifest itself. Handle the mobo, display and sim card like a stick of ram.
In 11 years I've only seen one tech install a sim card properly; ESD mat and wrist strap.

Hi!
Thank you for the detailed reply. Very insightful.
I've been at work for the last few hours. I left the phone powered off while I was gone. I got back and the phone is powered off, but the LED light is still blue. The only way to get that to go off is by unplugging the battery ribbon from the motherboard.
The phone was on at least 70% of battery before I left. I get back and it started charging at 20%. Mind you, it's been off while I was gone.
Do you think the safest route would be to unplug the ribbon until the new battery arrives?

If you think the battery has failed don't charge it.
Any swelling is a failure.
A sudden drop in capacity or erratic charging are also signs of a failure. I just went through this with my 10+'s battery
It's possible the battery was physically damage when the screen got broke, they're are really flimsy.
Best to rule out the battery.
It won't do your sanity much good until you do.
Examine the charge port PCB closely for any damage or solder cracks.
Examine the mobo as well. A stereo magnifying visor helps.
Hopefully the new battery will get it
Hello, I have the same exact problem. Verizon phone. Replaced screen from another phone. The phone boots normally, reaching the lock screen/home screen, but restarts after a few seconds. Performed a factory reset via the recovery menu, but now I'm stuck on the Verizon logo. Never-ending restarts. Never reaches the setup screen. The LED keeps on flashing blue-cyan at times despite forcing the phone off from maintenance boot mode (vol down + power). Tried factory resetting from there as well to no avail. Swapped back the old screen, but the boot loop persists. The battery is new (manufactured in 2020), had no random shut-off whatsoever prior to the swap, and had great SOT.
The worse part is the phone is undetectable via USB, the phone rarely fast charges. I suspect a burnt diode/capacitor on the mainboard itself because prior to the screen swap, I tried a daughterboard swap first. Both daughterboards work just fine and can handle both fast charging and data transfers on the donor phone. Both didn't work on the Verizon one. Can't even try flashing the firmware via Odin because of this.
Have you ever gotten to find a solution to this?

The part number on the daughter board must match the replacement. There maybe two US versions... if so they are incompatible.

I do have the SM-G925V (Verizon, 64GB) and SM-G925F (Global, 32GB). Originally, Verizon had a broken screen, a USB issue, and randomly restarts. SM-G925F did have a Knox-tripped mainboard and a faulty daughterboard, but only the 3.5mm jack didn't work.
Swapping only the daughterboards, I was able to use the Global just fine even after flashing the original firmware. The Verizon one despite having an older battery did suffer fewer random restarts and I started using it primarily as a hotspot device. The global one uses a newer battery I ordered online.
Prior to Verizon's factory reset via recovery menu, It had all the original components except the newer battery and the screen from global. I tried a reset because the random restart became even more persistent even while doing nothing. Now, Verizon is stuck, boot loop. I tried swapping even all the original components (older battery, broken screen) just to see if the phone will proceed to the setup screen. It didn't.
Were you able to fix the boot loop issue on your Verizon?

I know about because I ran into that problem on my N10+ N975U. Apparently there are 2 C port pcb variants. In my case the original pcb was still good so they just put it back in.
So much for preventive maintenance...

Sorry, I thought you originally posted the problem. I just noticed it was @TrumpXLV. Nevertheless, thanks for providing some insight. I did try to swap back all the original components on both of the variants, Global and Verizon. Did a factory reset via recovery menu on both, but only the Global one reset just fine and the Verizon one didn't.
I was curious if @TrumpXLV did find a solution. This is the only post I found that described the same issue, the same model. Might have to shelve this phone for now. Was planning to repurpose this phone in some way originally. I'm daily driving S10+ atm.
Hi. My close friend has this issue. I'm posting this because she can't figure it out by herself. A month ago, her phone downloaded an update and she installed it. Since then, the phone has restarted by itself without any reason, just random restarts and the frequency of restarts was more frequent with each day. Fast forward to this day and the phone is constantly turning up and shows the POCO logo and restarts by itself. This loop is not ending until the battery is completely dead. When trying to access fastboot or recovery mode, she can get there but only for few seconds (until the device restarts again) which is not enough time to make any changes / factory reset. She did not accessed developer tools in system, so the bootloader is still locked. Holding down power button does nothing. ONE SINGLE UPDATE screwed up whole phone. Can't do ****. There's no SD card or SIM card in the slot. Is there any "hack" to stop the phone from restarting itself? Note when the battery is completely empty and she plugs the charger, the whole nightmare starts again. I'm lost. Did you guys have any ideas what to do? Or is the repair centre only solution? (She cracked glass of the display, i'm not sure if that voids warranty. [it's not glass COVER, it's the glass which is part of the display])
Is this device unlocked? If not, then RMA.
If it is, my best guess is to get the device into recovery (or fastboot?) and immediately connect to PC.
If it holds, leave it there as it will charge, although at much slower rate.
When charged, use TWRP to try to reboot to system.
If it doesn't work, then factory reset.
Sadly, i can not get to recovery because in about 2 seconds the device will reboot. There's literally no time to make any changes - factory reset. Also the device is not unlocked. I hope RMA accept the phone even though it has cracked screen . Thanks for response anyway
Then RMA it is. If you're in EU they'll have to take it, even with the cracked screen.
But does the reboot happen even when connected to PC? Two seconds is enough to plug it in if you're fast...
Yeah, we tried every possible idea we can think of. Pressing the toggle button from different angles with different intensity to make sure it isn't stuck inside, covering up the proximity sensor (yeah makes no sense but even that we tried, lol). Tried with connected to PC as with classical charging brick. No change. Back in those days where smartphones doesn't have unibody construction and you were able to take down the back cover and remove battery it was way simple. Nowadays it's not possible to stop the phone from booting itself until battery is completely empty. My friend says the problem started about month ago, when the phone annouced that there is an update available so she downloaded it and installed it. Before that, there was no problem with the phone whatsoever. Maybe it's caused by some kind of virus but IDK which apps she was using. She didn't have rooted phone not unlocked bootloader in developer tools. Also i googled that it may be caused by "Airtel Thanks" app which she didn't have installed aswell. I will keep this thread updated as what happend to the phone cause i'm also interested what went wrong and to help future users who will struggle with this problem a solution. Thank you.
CaptainFedora, did you solve the problem? I have the same issue...
Yeah, actually. Sorry for not posting the answer although it was definitely her fault. It was the power button being pressed down (which made continuous bootloop). But the button was somehow pressed deep into the phone's body. So complete dissasembly was needed.
Btw. my friend lives in other country so we discussed this problem over internet. If i could have the phone physically with me i would definitely know what was the problem.
Hi.
Yesterday I had the same problem, the device kept restarting every 10 seconds, it didn't even come to any screen besides the first one with the POCO logo in yellow.
Things I tried that did NOT work:
restart
hard restart
fastboot (it did enter the fastboot mode, but only showing the picture of the 2 robots and after 10 seconds restarting again to the POCO logo image)
plug it to power
plug it to computer
After 3 hours of continuous restarting and trying anything I could find in the internet and I could imagine of (except extracting the battery because it seemed complicated and difficult to revert), I tried randomly something that miraculously worked...don't ask me why.
pressing the power button shortly and quickly around 30 times (it might have worked after 10 or 20, but I just kept doing it a little longer
Afterwards it just started as if nothing had happened...doesn't make any sense, but I just wanted to tell you in case you are in a similar situation and desperate to not lose all the images and videos as I was yesterday.
