Nexus One boot loop issues

Hi everyone,
I have a problematic Nexus One. I've googled the issue and read all the corresponding threads and none of them seem to have boot loop issues as bad as mine. At least I dont think so, anyway.
Where should I start? I recently bought the phone off ebay. The seller did clearly state the phone's issues and that he couldn't be bothered fixing it, let alone paying over $200 to send it back to Google to be repaired or replaced (from Australia). Call me a sucker for punishment, but I do like dabbling in electronics so I thought I'd give this a go and hopefully will be successful. It wouldn't bother me if it rebooted once every few days then rebooted again normally but this isn't the case. I'll try to describe it's behaviour as precisely as I an and I sincerely hope the collective expertise on this forum will be able to help me successfully resolve this issue. BTW, I've been using a gorgeous Desire since July.
The Nexus one is running Modaco r21, 4.06.00.12_7 radio, 2.6.32.9 kernel, CMR 2.5.1.0.
1. When the phone has been powered down for at least 5 mins, it will power up as normal. If left alone on the bench or very lightly used ie a few minutes, then pwr button sleep, no problem. If I continue 'sleeping' the phone every few minutes while using it it continues to function normally for a few hours. If I don't 'sleep' the phone and use it continuously, then after about 20 mins it goes into a reboot cycle with the static 'X' going on and off every few seconds then ending up with the continuously on "X" with the unlocked padlock underneath, which is unrecoverable until the battery is pulled.
2. Battery reinserted immediately after removal and the reboot cycle continues. I can boot into the white Recovery or Fastboot sreens but when I select an action like Recovery, the boot loops starts again. Battery pulled and reinserted again, boot loop occurs again. Pull battery and leave it out or powered down with battery inserted for 5 mins, reboots normally. Then point '1' above continues.
3. I have Rom Manager, Titanium and Superuser Permissions installed. I received the phone with Eclair installed and after many attempts managed to install the new radio and Modaco R21. Last night I tried doing a back up via Rom Manager since I cant get into the black Recovery screen and now Titanium and SU are force closing.
This is all I can think of right now and will update with more info as they come to light. I've been trying to install setcpu to see if underclocking will help however I have been unsuccessful due to SU force closing. I am an Android and Linux noob but am always willing to learn. I really would like to get more stability in this phone so I can either use it as my primary or back up.
Thanks in advance for all your help.
Edit. I magaed to do a factory reset when it dont momentarily allow me into Recovery mode. Wiped all data and davlic as well.

My first instinct is that the phone has suffered or is suffering from a heat problem of some type.
Do you have the android SDK set up on your computer? You should be able to flash an aftermarket recovery using the "fastboot flash" commands. You could also use the "adb reboot recovery" command to reboot the phone directly into recovery mode.

I'll give your suggestions a try. What fastboot commands should I be entering? I am an absolute virgin with all this.

I change twice recover and nothing.

[Q] Nothing but Bootloader...

Hey guys,
I recently got a new phone so haven't been using my milestone anymore and a friend offered to buy it from me.
So I of course was going to flash a stock sbf back on for him, i chose to flash 2.2.1.
I immediately ran into problems.
First off it worked fine, rsd (ver 5.3.1) gave me a pass, i disconnected the phone and rebooted, the android logo shows up and all is joyful in the world.
This is where the problems arise...
I rebooted into recovery to do a full wipe, and a cache and dalvik wipe, then i rebooted once more.
Instead of rebooting normally the phone now just goes immediately to bootloader.
No matter what i try it jsut alays goes back to bootloader straight away. there is no error message it just says ok to program blah blah like normal.
i've since flashed all the different bootloaders, the vulnerable recovery, every single moto sbf i could find, i even tried removing the volume buttons and keyboard to make sure the buttons weren't broken and automatically taking me there due to a short.
no luck.
did i kill this milestone? seriously, any ideas would be appreciated because i am totally stumped now.
Cheers.

Please someone help. I still havent gotten any further with this.

[Q] HTC Desire 500 Dual Sim Unable to boot after CWM

Hi,
My device is HTC Desire 500 (5060) Dual sim purchased 7 days back.
Android Version - 4.2.1
Yesterday I successfully unlock bootloader.
After unlocking boot loader I copied and pasted CWM-SuperSU-v0.98.zip downloaded from 'http://theunlockr.com/2013/12/20/root-htc-desire-500-dual-sim-version/'
However I was not able to enter recovery and apply the above downloaded zip, as soon as i select the recovery, the phone was getting rebooted. Hence I tried "fastboot erase cache" ("http://forum.xda-developers.com/showthread.php?t=1723670")
However this also did not help, so I had flashed 'CWMRecovery_D500_Philz.img' via adb (http://theunlockr.com/2013/12/20/install-custom-recovery-htc-desire-500-dual-sim-version/)
After flashing above, I entered the recovery mode and installed CWM-SuperSU-v0.98.zip via install from sd card mode in recovery.
Post this, the phone was booted up and i was able to see SuperSU, checked with rootchecker and phone status was Rooted!
While opening SU, it was asking for updating binary and while clicking on 'Update', it was saying update failed and phone got rebooted.
This happened for 3 times, hence I decided not to update SU binary and I update the supersu directly from google play.
However even after updating the latest version of Supersu, it was still asking to update binary which I ignored as the phone was getting rebooted.
Main purpose of rooting the phone was to install Link2sd to move certain apps to sd card and removing unnecessary apps. I had uninstalled google play movies, play books and play music.
After that I restarted the phone. Post restarting I was not able to move any app to sd and it was asking that no root permission, while in supersu there was permission granted for link to sd.
I checked the root status and now it was showing your device is not rooted!!
Again I tried to update supersu and it was giving me message that update via CWM for HTD device, hence i clicked on ok and power down the phone. After powering down the phone I tried to enter recovery via volume - and power button same as i did previously, however it did not work.
Tried to power on the phone, it did not work. inserted wall charger and the orange light was blinking but phone did not come to life. removed battery for half n hour along with sd card and sim card but no luck. Charged the phone over night, but still the orange led is flashing (no vibrates). Today handed over the phone to my wife and she visited the service center, the guy said come after half n hour I will check, after half n hour he said that you have rooted your phone and it is not under warranty, you have to get the main board replaced which would cost me around 5500 INR ($84).
Now my wife said that when she had a look the phone was powered on and she said that the guy also showed her that phone is rooted cause he has found supersu app:fingers-crossed: in the phone.
However as soon as he removed the phone from charger again it went dead. I have asked my wife to collect the phone.
Kindly help.:fingers-crossed:

Hi,
yes, you realised that you must flash a custom recovery via fastboot. You were not rooted after flashing supersu.zip because HTC phones have kernels with some kind of no-root protection. So for you could be solution to flash some custom rom with non-stock kernel(or flash only new kernel, that should be enough). I suppose there are some roms for your phone. Try to find rom which is almost stock, but with some additional features, like root access. BTW, this is Desire thread, no Desire 500, so try to find somewhere else.

Really thanks a lot for your reply as it has given me some hope. It will be a great help if you can guide me where to find custom ROM for Desire HD 500 dual sim as this model was launched in November 2013. Also if you can help me to guide to the HTC Desire 500 Thread. In device search I could not find my device listed on XDA hence I had to post in HTC Desire forum

Try to flash this kernel - http://forum.xda-developers.com/showthread.php?t=2600294. On post #24 is written, that this is working also on dual sim model. So with this kernel it should be all right (it disables the HTC System Write Protection which causes your problems). Good luck

Thanks all for the help. Things proceeded till now are as below. Service center guy asked to replace mainboard for 5.5K INR. I asked my wife to take the mobile back to home. When he plugged in the phone in charger it was booted and everything was working fine, when he plugged it out of the charger it went off.
My wife asked him again to put it in charger but it did not boot up (Waited for 15 minutes) and only orange led was flashing.
She asked him to check with another battery which is charged.
so service center guy tried his mobiles battery which was 80% charged in my mobile, but phone did not boot and same orange led was being flashed if plugged into charger with different battery.
After taking the phone back to home she just plugged in the charger and after around 10 minutes it came back to life itself (Without even touching the phone). Battery was 0% after around 3 hours of charging battery was fully charged to 100%, I asked my wife to remove the phone from charger and insert the sim card. Till now it is working proper.
I could not understand that why phone's battery was not getting charged even if orange led was flashing and it was plugged in to the charger whole night and today suddenly it charged and phone switched on without even touching the phone.

Same problem here .. Orange light after Custom Recovery & Gapps ......
i charge whole 2 hours but still dead .. not going to recovery mode

I am also facing the same problem. I flashed SuperSU and later its not starting. Screen is just black. Not able to boot into recovery mode. Orange LED flashes when I plug in the charger. I do not know what to do. Anyone has any idea ??

If you can enter fastboot mode (hold power and volume-), try flashing cwm or twrp found in the ultimate thread(http://forum.xda-developers.com/showthread.php?t=2597314). If you cannot enter fastboot mode, you phone is hardbricked. Go to a service center
If installing cwm or twrp works, follow filwatt's tutorial about getting back to stock.
Edit: cwm download is found in post #538

I am not able to enter fastboot also. Holding volume down + Power button does nothing.
Few minutes back I observed that my phone vibrated 5 times while plugged in. Does it indicate anything ?

I removed the battery and waited for some 20 mins as suggested in another thread..then put everything back it turned ON. But still I feel this phone is very vulnerable

You need to turn off fast boot under power options

Boot up problem
yesterday I unlocked the boot loader successfully and after that i flashed cwm recovery. On CMD screen status for flashing the recovery was OK but after that the phone went dead and not booting up. I had removed the battery and put it back but no luck except the orange LED is blinking if I connect the phone with charger. So anyone here with solution for this problem?

July OTA Update Bricked my Phone -- AT&T refusing to replace. Help!

Completely untouched phone from AT&T. Have never rooted or modded this phone in any way.
The update that came out this month was sending my phone into random boot loops. Would have to take the battery out and after a few tries it would stay on for a while then at some point in the day randomly go back to the boot loop.
I backed everything up through Kies then went into the recovery menu and attempted a factory reset. This sent the phone into a permanent boot loop -- would never turn on or off. Sammy logo flashes and it would reboot. Only way to get it to stop is to take the battery out.
Attempted to go back to 4.4 through Odin since those where the only firmware files I was able to find. Updated failed. Now, when I turn it on and I just get "Firmware upgrade encountered an issue. Please select recovery mode in kies and try again."
Kies will not recognize phone. Cannot update firmare from internal storage because I can't even get into recovery menu -- it just goes right back to the same screen.
Called AT&T and the rep told me he would replace the phone through warranty even though I was past my warranty date. He told me this update has messed up a lot of phones and this is not the first he's of it. Then his manager gets on to approve the warranty replacement and she refuses to honor his promise -- tells me they won't do it, I'm SOL, and I can use my upgrade. Maddening!
Please help -- I need a working phone!

Most attempts to downgrade only flash the kernel so here is the OF2 kernel which should get your phone to boot again. Flash with Odin:
G900A_OF2_Stock_Kernel
Once your phone boots place the G900A_OC4_tF2_OTA.zip onto your extsd card and flash as update from stock recovery. That should get you back to 100% factory stock. Do a factory reset after flashing and if it still does not work I suspect a hardware problem.

Thank you for the reply!!
Kernal flash worked and I was super excited to get back to recovery menu -- way more progress than I've had up until now!
Unfortunately when it went to reset after installing the update from external storage, it went straight back into the Sammy logo boot loop

Is there physical damage on the phone, thus why att didn't do the warranty?

No idea what just happened. I've been messing around throwing the kernel you recommended at it as well as the stock partitions. Kept getting back to boot loop but at one point it stuck out, said it was upgrading, optimizing apps, and now it's running. So weird.
I'm way too scared to do the factory reset at this point, though.
Thank you again for your help, I really appreciate it!
Edit: Unplugged the USB cable and it immediately shut off and went back into boot loop. Wow.

this sounds like a hardware problem.. i sent my phone to Samsung and they actually repaired it, it was the pba board, i had the same problem.. i flashed everything it needed to recover from a bootloop. and sometimes it would become non responsive. go to best buy and see what they tell you.
Sent from my UNROOTED SAMSUNG-SM-G900A on OF2

Update:
Thanks to everyone for their replies. I was able to get the phone to boot thanks to everyone's help. Did this by flashing kernel then partitions which would allow the phone to boot.
I finally figured out that the phone would only boot if plugged directly into a power source. As soon as I disconnected the power cable, it would send it right back into the boot loop. I ran some battery "repair" and "calibration" tools but these did not fix the issue. Whenever I would run a battery drain tool, the stress on the battery would cause the phone to shut down.
All of this led me to believe it was an issue with the battery. I held my wife's S4 battery to the contacts on the S5, and it works just fine, even disconnected, and even with the stress test on the battery.
SO -- I'm going to buy a new battery and see if this fixes my problems. I think I just had the perfect storm of battery issues coupled with firmware problems.
I'm pretty sure I know what caused the battery to go haywire. I work in a max security prison and have to leave my phone in the car all day. Outside temperatures regularly hit 105F+ during the summer, so who knows how hot it's getting in the car. Obviously I always leave the phone turned off, but I suspect the high temperatures caused the damage.
Going to try to find a new battery today. Will keep everyone posted! Thank you again for all of the replies.

I had the same issue and would just like to thank you for the files! They helped me unbrick my phone! Much appreciated.

HTC one m7 keeps restarting to first htc white screen

Can someone please help. I have searched on here to find a solution for htc one continuously restarts to htc white screen. Powered by android in black writing. I have tried many things like holding down and power to get to fast boot screen but phone will just keep turning off and on again. holding it into the light while holding power button. no success.
It was working fine one one day then went to look at my phone and it was wanting to turn on and off, over and over again utill it went flat.

that's odd.
try pressing the power button and holding it for 8-10 seconds. If your phone powers down try to get to the bootloader; press and hold the vol down key and then press the power button and hold both buttons down for 5-8 seconds.
What ROM are you on? Custom ROM? Stock ROM? If stock, what version of android you on? Stock sense 4.x has a fastboot option and you need to disable it before you can boot into the bootloader.

Hi again.
I have tried what you have said with no luck. The restarts are getting more frequent and annoying. what I can get to is the bootloader then into team win recovery, and have tried wiping cache. but even this keeps restarting from here.
The sense version i could not tell you as I cant even get into the phone. but here is the downloaded software that is installed. OTA_M7_UL_L50_SENSE60_MR_Optus_AU_7.21.980.22-7.21.980.5_release_432037.
It is rooted and s off.
If possible at all I would like to be able to continue using software updates which I havent been able to previously do since installing this version.
Thanks again for your reply.

reflash the RUU that you have flashed back in November. If the problem still persist after that, its an hardware problem.

Maybe you have problems
