HTC Touch Pro 2 Dead!!! Please Help!

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.

Omnia repair tool can fix it

battery voltage low

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!!

Screen got totally black randomly and then started blinking.

I just got the moto g
I had updated to marshmallow just after opening the box.
It's the second day of the device and the display just turned black all of a sudden. On screen buttons gone too.
I pressed the power button and the screen turned off. When i turned the screen on again after 5 secs the screen turned black again.
I turned the screen off and on again.
This time the screen kept blinking. It didn't turn off just the contents of the screen kept blinking.
After I rebooted the phone, the issue disappeared.
I'm not sure if it is a software bug that happened or early signs of some hardware issue. I still have the 30 days for replacement.
Rest of the device is working fine.
Has anyone found the same issue?
I am using stock software, no root.

Yes brand new stock moto g updated to m and had the exact same issue, it's happened once a day so far to me (I'm on day three of owning the phone) A reboot fixes it but it's annoy I don't want to have to reboot the device all the time. I can see it being annoying trying to get the device swapped because when I wipe the device to give it back to the shop it will be working fine :-\
It just seems to happen randomly, nothing to do with a certain app I don't think, I can't replicte it when I try to figure out the cause of it.

S6 Edge Battery issue or OS issue? I'm new, help please

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.

Question Moto Edge 30 - Restarting and Hanging

Hi all,
I recently bought Moto Edge 30 device and after a month of usage, I have this issue - The apps started crashing randomly and the screen gets frozen and restarts. Sometimes it gets stuck in the boot loop until I go to recovery mode and reboot the device again. What could cause this issue?
I got it checked in a service center and it was mentioned the charging port has liquid damage hence it's causing some issues with the motherboard and hence the restart problem. The charging and turbocharging in the device work fine and even it connects to the PC and works fine. Is there any truth to what I have been told?
If anyone has encountered a similar issue, let me know if there's anything I could do to fix this.

i had something similar, in my case my edge 30 would randomly shutdown, and id know because when I pressed the power button it would start booting.
the service center identified it as a motherboard defect and replaced it. it's working fine now.
