Hey, guys, I know there are a lot of these issues with a lot, if not all, of the HTC smartphones, but I've only seen a few of these for the HTC Radar, and they all seem to give the same answers. Hopefully my explanation of the problem will help!
So, I got the phone thanksgiving weekend 2011, so I've had it for about a year. One day around the beginning of April this year, my phone randomly began a restarting loop, where it would gradually restart itself from a blank white screen over and over, then it went to the HTC screen over and over, and then periodically switched between the HTC screen and the black "Windows Phone" load screen over and over again. I tried taking off the battery cover and leaving it for a couple of minutes and then hours, but I put it back and it just kept rebooting. I was left without a phone for about two days.
On the second day, I put it on the charger and left it in my dorm while I was in class all day, and when I came back, it was rebooting still, but I noticed that it always made it to the "Windows Phone" logo loading screen and then restarted. After about 4 reboots, it went back to normal and I was able to use the phone. After the next couple of months, it stopped doing it in such a long period of time, but the battery usage went up almost 30-40% than what it used to be. Once in a while, it would reboot once, but then it would be back to normal.
This time, in late October, it started the reboot thing again, but this time, only going up to the HTC screen and looping that. I tried taking the battery cover off again and leaving it for hours, but same problem now. So I decided to leave it off for a day. By this time, I had my HTC Desire HD as backup, but it was unlocked, and at the time when I bought it, I didn't know anything about HSDPA numbers, so I could use my T-Mobile SIM, but no mobile network, since it's a Telus/AT&T phone.
I tried charging it, but this time, it lasted for a whole week. After rebooting over and over, it would last 3 hours, then stop because the battery would die out. So I just left it, and left it, and weeks went by, and my warranty had long since expired, so I couldn't go to HTC about this. I even called them to see what I could do, and they told me to do a Factory Reset, well... here is a list of the things I tried:
- IMAGE CRC: At first I didn't know what this was, and so I looked it up. After finding out what it was, I tried it, and I got two numbers: BL CRC-0xD19F79E1 and OS CRC-0x4CC706B. I looked those up on the internet and got nothing. I restarted the phone, and nothing happened at all. (If there was something else I was supposed to do here, please tell me!)
- Factory Reset: This was the LAST thing I wanted to do, but I had no choice and I tried it, hoping the error would be fixed. So I scrolled down to it, everything seemed to be normal, it gave me a warning, and I clicked it ... I was very suspicious of this, because as soon as I clicked "Factory Reset", it said "Reset complete. Press Volume Down to restart". I mean IMMEDIATELY after. Now, I KNOW that Factory Resets take much longer than an instant to actually have happened. But I restarted anyway. ... Nothing, still. I tried it several times after that, only to get the same result.
Those are the two options I tried, besides looking on the internet... if I can avoid buying a new Radar, I would like to, at all costs, because the next time I have a decent amount of money, I would like to save it for something else. Is there anything else I could try to resolve this issue, or at least gain more information on the problem?
Thank you all very much for reading my post!

May be it is a Hardware problem. Why you don't try to put HSPL and to cook custom rom ? I do this on mine few days ago and now the phone is more useful than before. I cooked HD2O ROM and till now working fine for me. When you change bootloader with HSPL may be it will work out if it is a Software problem. Also you need to change Radio Firmware other wise the device can not boot. When I am doing HSPL a few times phone just loop restarts and not start but after I do everything like it was in treads here and flash new radio the phone is working fine now. But may be there is a Hardware problem.

Thank you very much for responding! So just to be clear, how exactly do I go about flashing a ROM on the Radar, and a new radio? On Android phones, its much easier to root the device or simply place the ROM folder in there and make it work. I have no experience with doing this to a Radar, as I was previously led to believe that this was impossible. Should I just browse this forum?

Yes just browse this forum but only section about Windows Phone 7 Development and Hacking. You will find DFT exclamation of how to install HSPL. In mine it was very easy because I not receive Country ID fail my phone was buy in Europe. If you receive Country ID error you need to proceed with goldcard it is explained there but first proceed without goldcard if it work it is very easy. Also when you proceed SPL2.05 it is not clear in the topic but you need to be in bootloader so you should start your phone with VolUp and VolDn keys pushed this is not explained in the topic and I waist a lot of time till figured out. After that just download one of the 7.8 ROMs here in Radar section and write it down. Also download new radio and use some RUU to put it on the phone before the ROM other wise the phone can not boot. Try and after that if you have problems write down here.
MY RADAR TURNED BACK ON! I don't know exactly what happened, but after a couple of reboots, the battery indicator flashed and then it rebooted twice until finally turning on the full amount.
Tonyco1 -- Thank you very much for staying with me and replying to my request! Although what you suggested is not needed for my booting issue, I'm going to try it anyway to see if I can actually boot 7.8! Thank you again.

OK but you need to but some custom ROM my phone turn back on when I put custom ROM a lot of features and works really good.
I'm having a huge problem with my T-Mobile Galaxy S2, and not it won't even completely boot up. The issue had already been around, but never this bad. Usually, when I would use my phone, it would just randomly reboot on it's own. Now, I can't even get to the main home screen or menu. When the battery is inserted, the phone will automatically try to turn on. I'll get the Samsung screen, then the "Samsung Galaxy SII Android 4G T-Mobile screen", then the phone will glitch for a second, black screen, and it'll almost have a seizure from then on. When I say that, pretty much what happens is that the screen will go black, and it'll pulse with vibrations. It'll vibrate, stop for two seconds, vibrate some more, etc. That's all it'll do from there on. It won't try to turn on when I hold the power button, and the vibrations won't stop until I take the battery out. There is no water damage, and there's just normal wear on the phone. I've had the phone since the drop, and for the most part, it's been great until now.
The phone is not rooted, and I have not installed anything crazy. Come to think about it, I didn't really even have too many apps installed on it to begin with. The phone is under warranty, so I had T-Mobile send me a replacement. My main issue now is that I have content on there that wasn't on my SD card, but on the internal hard drive that I find extremely important, and want to keep. When I connect the phone to my computer, nothing comes up because I didn't "connect" it to the computer as you normally would have to do from the phone, before the extra drives pop up on the computer. Without getting into the main menu and manually connecting the phone to the computer so that the drive will pop up, what can I do?
I've tried taking the battery, sim card and memory card out, letting it sit for a few hours, and plug it back in, but it does the same thing. The battery isn't bad, because it plugs into the replacement phone that was sent to me, and works just fine. I've also plugged into my additional batteries, and it does the same thing. I can't do the "hard reset" where you hold volume up & down, then the power button because what happens is the phone will restart itself before I can get to that point. I tried it when I was on the phone with T-Mobile, and the associate at one of the retail locations tried when I went to get a loaner. I've tried hooking up the phone to the Kies software, but it won't recognize the old phone. It will recognize the new one with no problems though.
I am in no way am I well versed with the process of flashing it or installing different things on the phone. I just used it casually for phone calls, texts, web, and an occasional game or app. I'm just stating this so that if there are any specific tips that anyone could recommend, please if possible, explain in a bit more depth, because after I posted my title, I found the related threads, and most of the steps that were recommended to others that had problems sound a bit foreign to me. I just really want to recover the photos and documents that I had on the phone before I send it back to T-Mobile.
These are the threads that I've somewhat referenced so far:

a usb jig to get see if you can get to download mode would be a start.

You described my phone EXACTLY. I have tried everything you have, as well. I've read for hours on the internet trying to find a way to retrieve my pictures, etc. I have a replacement as well, but I haven't sent the old one back yet. I should have done so already, but I desperately need my stuff out of this phone. I'm going to be charged soon for the new one, and was trying once more before I sent it to the company. Exhausting all the info and tricks I've learned from the web, I ran across your post. Can you PLEASE tell me if you had any luck at all? Thank you....

Tonight out the blue my S2 galaxy skyrocket got the same exactly problem that you described. except for some dumb apps my phone has not been ever modified. I don't know anything about phones. for a couple hours y tried every combination possible of volume down, power button plug cable to computer in every sequence possible several times. at the enI stared trying with the Volume up I was fearing it will star a OS download or something at some point the Samsung logo stays a little longer and started the normal booting sequence. PHEW I got my Notes back. Hope this works for you. good luck

That's nice, but this is still in the wrong forum. The people who could benefit from it won't see your 'help'.
I have a Galaxy SIII through US Cellular (about 6 months) and get strong 4G service. Recently, when placing a call, the phone will ring a couple times (1-4times) and then will just end. At first I thought I was getting hung up on, but it was happening a lot, so I tested it by calling wife's phone, same thing happens. IT wont do it every time, but it happens pretty frequently. I decided I should update to see if that helps, but it didn't. Have tried all the little tricks (update, restart, pull battery, etc). The phone has not been hacked and I don't have a ton of apps or change anything prior to this happening. Thoughts? Thanks for any ideas.

first of all this is an international GS3 forum. coming to your problem, try backing up your apps and factory resetting the device from recovery mode. good luck
So I recently got my old bricked evolte replaced by Sprint. The one I was given worked fine the entire time the device was powered on. However, once turned off and back on, its screen would not work. It stayed like this for hours, until I finally started playing with it and realized it would come back on after playing with it for a little bit. I also found out that with this error the home screen pops up for a second when powering on your device, and that's exactly what I had. I read up on the error and found out it was a software error, and to reset to factory settings. So, this fixed it, I thought.
So now, after it is apparently fixed, it still does this to some extent. It will do this if the phone has been powered on for a while, and the screen won't stay off for more than like 2 or 3 minutes. Also the home screen doesn't pop up any more like it used to with the other error.
So what should I do? I was thinking of going to Sprint, but my problem is hardly reproducible. It only happens when it's been powered on for a long time, and won't do it twice in a quick succession. I feel that even if I could show them the problem, they might think they've fixed it when they haven't because it won't do it twice. I would like to root my device, but I'm afraid they're going to say that I'm the cause of the problem if I do that. If it's just a software problem though, maybe flashing a custom rom would fix the problem.
What do you guys think? What do you think is the best course of action? Any advice would be greatly appreciated. Thank you.
Never mind, I didn't know Sprint would order you a new phone if it was a minor problem like that. I thought they would only repair yours. So feel free to close this thread.
Hello:
So, the bottom line up front is I need help solving a problem with my now third, new Verizon Samsung Galaxy S4--it keeps restarting on its own, at random times, but most often after I lock the screen.
To go in more depth, if you think you may know the solution: I purchased the S4 when it first came out, some time in 2013 (not sure specifically, but it was new) and it worked just fine for 13 months (1 month past the warranty of course); this was back in August, when I got the latest Android update pushed to my phone from Verizon (4.4.2). A couple of weeks later, I would occasionally get overheating warnings that would very quickly disappear (like within a few seconds), and then the device started restarting itself... I cannot predict when it will restart, it's random, but like I said above, it usually happens most right after I lock the screen by pressing the right side button once. I started looking around on the internet for a solution then, but only found a couple of videos from earlier in 2013 where people were having battery problems (Google search has been letting me down more and more as the years pass). One day while at work, I was listening to Pandora as I always have with the phone in my front pocket, as I always have. A few hours later when I got home, not having taken the phone out of my front pocket since those last few hours at work, I went to answer a text message I had received; when I unlocked the phone, the screen was black, except for a small bit of white showing through some cracks UNDER the LCD, UNDER the screen protector, INSIDE my Otterbox Defender... the phone appeared to be working still, but the screen and touch screen did not. At that point I was pretty damn irritated and tried to find answers for a week with no luck... I called Verizon, they sent me on a goose chase to Samsung, who sent me back to Verizon, who got me in a conference call with Samsung and then left the call, and then Samsung ultimately said I would need to pay for repairs to the phone... SO... I went back to Verizon who again said I would have to talk to Samsung, but instead I just settled to giving Asurion (my phone insurance through Verizon, whom I pay an extra $9 monthly) $99 as a deductible to get a replacement S4...
Two days later I receive a brand new S4... spend hours setting it up the way I had my prior one... wasting tons of my valueable time to do so and bandwidth from my Concast ISP and the data cap they've decided to give us... one week later, the phone starts restarting itself... and this one did it more often than my prior one... EVERYTHING is up to date, minus a good amount of useless bloatware apps I never use from Samsung, like "Watch On," which I ignore... but everything necessary, I update. So, I go back to Asurion, who quickly ships me a 3rd S4...
Two days later I receive that third, brand new S4... spend hours setting it up the way I had my prior one... and now, this one is also restarting itself randomly. Interestingly, when I visited family for Thanksgiving, it restarted itself over and over and over much more frequently than when I'm at my place... at my family's place, they have very poor reception, and my phone usually has to work more to try to get the signal... IDK what the deal is, but maybe that information can be helpful to y'all.
Other things to note:
1) When I check the "RAM manager" by holding down the home button and then choosing "Task Manager", the phone is always using at least 800MB of 1.77GB of RAM... even when I choose "Clear memory" and it tells me 30 something apps have been closed... it jumps right back up to 800-900MB of usage.
2) I've tried factory resets on all three phones; with the first one where the screen cracked inside, I hooked the phone up via HDMI... within a couple of days, the restarting begins.
3) With the first replacement I received, I could not sent text messages with the default messenger app... and shortly after trying, it would restart.
4) I have used the same SIM card with all three phones since the issue began, when I first got the 4.2.2 update... I do not suspect the SIM card is the problem, but I'm also not savy with the phone... I know my way around it, but I'm not in the know.
5) I thought maybe it started because of some apps I had been trying, so I had deleted them, and the problem still persists.
6) I constantly have a Pebble Bluetooth smart watch connected to the phone... I have since I got it last Spring (2014).
7) I have never rooted the S4, overclocked it, underclocked it, or modded it in anyway because I do not know how, and I was afraid of what could happen in the future with whatever ROM I did flash onto the device if Verizon tried to push an update to it... I just don't know anything about the whole process, and I'm assuming it requires a lot of know how and babysitting of the device... I just want it to work.
8) I've replaced the battery twice; it doesn't seem to be the problem.
9) I've cleared the cache through the boot manager thing gotten to by holding a combo of buttons on the device while it's rebooting... it did not help.
Edit: 10) Today while I was listening to Pandora in the car, the audio began to skip and scratch, and then it paused for a moment, and then the phone restarted itself.
11) I forgot to mention that the reboot process itself is very fast compared to a manual restart performed by me... the phone will go black, the Samsung color rings will show a second after that, the logo appears then, the screen flashes the red Verizon logo, and then the devices is ready to be used... it's less than 10 seconds.
I've been searching around on the internet for about two months now while dealing with the problem and I can't find anything useful. Does anyone here know what my issue is and how I can fix it? Is there a way to pull error logs / information from the S4 somehow to give to someone to diagnose, like DxDiags on PC? I don't know how to read that stuff myself, but I know it can be very useful... I just don't know how to find that info inside of these very locked down ****boxes we call smartphones...
I truly appreciate any help I can get--sorry I can't offer anything in return; if I can't find a solution, I'm just going to go to my backup phone from 2011 (Droid X), and I will definitely never purchase another Samsung device, especially after they blamed me as the cause of the problem without even seeing the phone...
Thanks.
The problem is with the NG6 software build, and "probably" not with your phone. Go to Settings>About Phone> and see what Baseband Version is on your phone. If the last 3 letters are NG6, that's probably the problem. There is a new OTA update (as of 12/1).....Baseband Version ending in NK1, which corrects the rebooting problem. Either install the new update, or go back to the NC5 baseband version and that should solve your problem. Both NK1 and NC5 can be rooted if you desire.
