Phone wont turn on - need to send to verizon but its rooted

I recently got a microusb to usb female cable and was playing around with it on my s3. I wanted to see if the s3 could power a laptop cooling fan (Im a curious guy) and plugged in the usb cooling pad. The pad worked to my surprise but it suddenly shut off. I look at the s3 and the s3 is off too. I try turning it back on but that didnt work. I try taking the battery out and then turning it on but that didnt work. I plugged it into a charger and tried turning it on but that didnt work either. I even tried booting it into download mode and that didnt work. I have tried almost every troubleshooting method including trying a different battery and that did not work either. My phone is rotoed with CM10 on it and I need to send it back to verizon once I get my replacement. Is there a way to reset the internal sd card even when the phone wont turn on? Will verizon even find out if the phone is rooted if it wont turn on? Has anyone ever sent in a rooted phone to verizon once they got a replacement and been ok? Your help, thoughts, and any input would be greatly appreciated. Thank you. (As calm as I may sound i am freaking the crap out right now).

My first tip is to stop posting the same question. It's been answered in your previous threads. Just like droidstyle said they won't know if it's rooted unless you tell them. As far add testing the internal memory, there is no way since it won't turn on.

[Q] HTC inspire 4g wont turn on..

I just got my HTC 4G inspire device from Last Sunday and 5 days later on a friday night i was talking on whatsapp when the phone froze and shut off and it wont turn on again!!! i tried power + vol down but still wont boot into HBOOT...but when i connect to computer its recognized as "QHSUSB_DLOAD" with driver not found...PLZ any help? im rly dissapointed cause i wasnt even doing anyting for this to happen??

quick question, when you pluged it into computer did you see anything on the phone screen. Is the phone rooted? if so what rom is on it. Reason I ask about the plugging in to computer part is I have seen a phone batter lose connection or go bad. If it is not rooted or anything you can call htc and they will help, I have never had that happen to me i dont use that app.
i googled the dload issue thing your having, i seen a few videos on youtube. I could not watch them as i am at work. I would google that though and see if those videos will help you or not bud.

So the next question is where did you buy it from? I would call or go in person and request an exchange. Most places have policies where you can exchange within x number of days (usually 14 to 30 days). Otherwise shoot for warranty support.

Nexus 5 won't connect to anything over usb

So recently I started having this problem. My Nexus 5 stopped charging all of a sudden.
After messing around I found out that I could charge the phone when it is turned off, but when I boot it (while connected) it doesn't show the charging icon. Only when looking up the battery status at the setting menu it says charging.
To my surprise fastboot was still working (adb wasnt) what brought me to think it's not the hardware.
So far I have done a factory reset, wiped everything, installed stock kernel and recovery, downgraded to stock 5.0 (I don't even know why, just thought its worth a shot...).
At some point I took the phone apart to try to determine whether I tore out the connector itself, and noticed nothing.
I'm really running out of ideas here... I can live with having to reboot the phone for charging, but I really need it to connect to the computer.
Any help will be appreciated!

You tried different USB cables and chargers? USB debugging enabled? Computer is a trusted machine in adb?

I have 2 computers on which adb is trusted. Both stopped working. I tried a few cables, all of them worked with another phone, but did not with mine.
Adb is enabled. :/

Did you try revoking all computers and re-establishing trust after flashing a stock ROM?
Strange that fastboot commands work and adb doesn't.

Nope, but I tried connecting to another one and no dialog popped up.
Btw, an hour ago it just started working... All of a sudden...
I should be happy, but now I have no chance in finding what was the problem.
Anyways thank you for now, if I have any more issues I'll update.
I assume it's physical damage to the usb board/module (since it started working while no change to the software was done in the past few days).
I will order a new one just in case.
Thank you again guys!

Maybe a loose internal connection? You could try removing the back to looking for loose connections.

Did so, didn't notice anything strange.
I do have experience with soldering, but I would rather not touch it before I get a new one, just in case I screw up. Small components are no fun.
The thing that still bugs me though is I had fastboot working perfectly fine all that time. Oh well

Having some issues with Samsung Galaxy S6...

Hey there,
I'm wondering if there may be a problem with my Samsung Galaxy S6 and I wanted to get some opinions before I try one last thing and fully reset it.
I've had the phone since April last year and for some reason the battery life has never really been good anyway. This isn't the main reason I am posting though as only recently I noticed a different issue when I tried to transfer some files onto the phone.
I was trying to use the cable that comes with the phone to charge it, and I've done so before when I've transferred files before from my Macbook. However, that time before I also found it very difficult to detect the phone and kept having to unplug it and plug it back in before it would see it. I was using the software Android File Transfer. Last night I could literally not get it to see my phone whatsoever... I plugged it into the computer and it would charge but it literally could not detect a connected device.
So here's where it gets frustrating as I spent the next two hours trying to fix this issue. I tried searching for a solution online which is why I'm now here after everything as all that I tried didn't work. I tried switching to SmartSwitch (and uninstalled AFT first), but that program also didn't detect my phone. Then I tried Airdroid, which worked only when I used the file upload under the browser but refused to connect to the phone when I clicked it on My Devices.
I even tried the method of *#0808# but it was actually already set to the correct settings so now I'm completely at a loss as to what it could be.
I've previously also had issues where I've plugged in the phone and it hasn't started fast charging and I haven't realised for an hour that it's only been cable charging and had to plug it back in for it to recognise it... is this likely a problem with the phone or cable?
I mean, aside from the also frustrating battery issues which have been worsening as time goes by (currently phone is on 79% having only used 39m screen time), I'm not sure whether it's time to give the phone a reset before actually taking it in to the store or whether it's likely an issue with the connector port at the bottom too which means it's probably not worth the hassle of resetting?
I won't go too much into the battery issues here, but I've been trying to use Greenify, App Optimisation, literally EVERYTHING I can think of, and I still don't get any more than 4 hrs and a half screen time.
My phone is not rooted. (though I'm wondering whether rooting it may help me). Thanks and I hope you have some advice that may resolve my issues!

I have the same issue.. muy phone won't charge unless otra on the wireless charging port

I have the SAME issue. I really don't know how to fix it!

Hmmmm sounds like your charging port is starting to go either that or maybe you could try flashing some new software through Odin and hope that's it's a software issue and as for the battery of course rooting does help bc it lets you get rid of the bloatware on the phone either that or try package disabler pro.

Cannot root Oneplus 8T because my computer absolutely refuses to recognize it, so I can't toggle immersive mode. Anything to be done?

I don't want to get burn in on my phone, but I tried for 6 hours today to get this rooted and it was just one problem after another, most of which I see have barely happened to anyone. Between driver errors, installing driver errors, unauthorized adb errors, some strange error with a missing key or something, and it saying it's waiting for a device when attempting to run the boot image, I had to give up because everyone around me was getting annoyed by how much time I spent on it. A simple guide of maybe five things I had to do turned into a huge rabbit hole, it even resulted in my phone inconspicuously seeming as though it's bricked for a few hours for some reason.
So my question is, is there anything I can do? I'm a gamer, and I have OCD to boot, so when I see those damn icons burnt into my screen when playing something, it's gonna kill me. Is Tasker an option? Man, this was much easier on IOS, surprisingly.

Well first off, it would help it you told us what os is on your computer..

Oh, sorry about that. Windows 10 Home. It's a couple years old now. An Acer Aspire 5. It has been giving me driver troubles for a long time, which would explain why it's made it so difficult to root.

The "waiting for device" is symptomatic of a missing driver.
There's a number of threads on installing drivers/connecting to PC in https://forum.xda-developers.com/f/oneplus-8t-guides-news-discussion.11585/
I even write one of them with lots of screenshots.
If none of them work then I suggest you have issues with your PC or, if you can't see your phone at all using MTP, your physical contention between the phone and PC.

Have you tried using a different USB port and USB cable? It's possible the port/usb cable is damaged and causing issues. swap both with a different USB Cable, make sure it's a thicker cable and not a cheap one. if you're using the C to C cable that comes with the phone, try using a USB C to USB A adapter.
