Unfixable boot loop... Help?

Hey everyone,
So this is my last ditch effort to attempt to save my device. I would really prefer not to perform another warranty exchange given that I am not under insurance, but I'm afraid I have no choice.
My phone was rooted and I was using Darkside without issues, as I had been for the past two weeks. I am always careful when I flash roms and I made sure to follow every possible protocol. That's the background information.
My battery life was running at approximately 6 percent yesterday and I sent a text message as normal, and it was stuck at sending. I tried turning wireless data off from the toggles in the pull-down and it was unresponsive. When I went to Wireless Network in the settings option, my phone rebooted. Once it started up again, my service would not come back, and the phone would continually bootloop once it got past the traditional "media scanner running", etc. My window of opportunity to do anything was really slim.
I charged my phone to see if it made a difference, but it didn't. Tried with my SIM card removed and it still bootlooped. I was able to get to CWM from the advanced power menu before it rebooted again and I fixed permissions and cleared cache and dalvik. Now the phone wouldn't even get past the boot animation before rebooting.
I put the phone into download mode and reverted back to stock using Odin. The phone now got past the boot animation in stock mode, but was unable to find service and after about 10 seconds fell into the same bootloop pattern. I tried removing the SD card but that didn't help either. Using Odin again, I reflashed recovery, followed by root and tried reinstalling a rom through CWM (I have only used regular CWM, not the touch version) with a superwipe to ensure a clean flash. Once again, it wouldn't make it past the boot animation before bootlooping. I reverted back to stock using Odin, and this is where I stand.
I have tried all traditional methods to salvage the phone and, for the life of me, I cannot understand what happened. The only thing I notice is that regardless of how long the phone stays on before rebooting, it is never able to find service. It's like the radio or modem broke and the phone has no other choice but to restart forever. But reflashing the stock UVKL1 should also reflash the proper modem and radio, right?
Has this ever happened to anyone? Any suggestions (aside from the typical reverting to stock) as to how I might be able to stop it? I searched but haven't been able to find a situation quite like this one. Thanks in advance for your help.

Really sorry to hear about your problem. Assuming the 2.3.6 stock image you flashed via Odin is the one provided by Przekret and that that didn't work, then I'd try one or both of these two longshots to try to clear possible corruption problems in either the kernel or modem spaces:
For each of the following wipe cache and Dalvik cache in CWM before flashing and again wipe Dalvik afterwards and also fix permissions:
1) Format system (do this 3x) under mounts & storage in CWM. Flash the standalone Darkside kernel X v1 final immediately after flashing, e.g., the current Darkside rom. (You'll need to wipe data, too, if not coming from a Darkside rom. Do not do any Superwipe - neither the standalone version nor using a flag.)
2) Flash the KID modem (do this 3x). Both Odin- and CWM-flashable versions are available. (You can always flash back to KL1 if the problem is fixed.)
Hope this is clear. It's late! These are both things that have helped get my phone out of troubles, though not as bad as yours. Good luck!

Also if u used the one from przekret then I'm almost positive that Odin package flashes the new radio too. If memory serves me right. Op let us know what happened

Thanks for your help. Unfortunately, nothing has worked. I'm on the phone with T-Mobile, I see no other solution but to get it exchanged under warranty and it's not getting here until March 15th, according to the representative. I suppose I'll just use a replacement phone in the meantime. It's just really weird and frustrating... I could understand a bad flash or something similar, but I followed every step accurately as I always have and everything was working just fine until it randomly decided to die without warning.

Well since you're getting another one anyways I would continue trying to fix this one, just in case you come up with a solution and for another worst case scenario for your new phone.

[Q] Help I deleted a system file

Hey I got my phone rooted, so I installed Titanium Backup, and then I uninstalled the stock browser, the download manager, and also android.downloader or something like that. And I broke my phone - now Google Play just crashes instantly.
I've tried reinstalling the firmware, and resetting to factory, but it's still the same.
Is there anything I can do, other than take it back to the store?
Help!!!!!
EDIT: It gives the error "Unfortunately the process com.google.process.gapps has stopped."

did you do a nandroid backup?> if not we need to know the exact application you deleted. future reference DONT DELETE. just freeze then its just a simple unfreeze and a freeze also stops the app from running. you will not get more available memory by doing this because this is on a different partition. Also never delete or freeze anything referring to com.android they are core funtions that are required for your device to run properly.

You deleted a process?!
My money would be that android.download or whatever process you deleted was required for Google Play to work. Hopefully you made a Nandroid before modifying processes. If not, you'll have to flash a stock ROM to get it back.
Alternatively, if you backed up system data with Titanium Backup, you might be able to find the process in there and restore it.
Echoing drksilenc, don't uninstall things through Titanium Backup unless you're positive it won't mess something up. How can you be positive? One, deleting processes always causes problems. Even freezing them can be messy. Don't do it. Two, in the case of an app, you'll know it's ok if you've had it frozen for a week or so and the phone hasn't acted up. Even with system apps, though, I recommend freezing rather than uninstalling. It's safer, and you never know if you might want/need that app again.

It gets worse.
I went down to the Bell store (my phone's actually from Bell, but they're similar to the AT&T ones, right?) and they wouldn't exchange it. So I tried going into the Clockwork Recovery, and wiped all of the little folders in "Advanced Settings." Because I noticed that Bell's add-on apps kept coming back, why weren't the other ones I deleted? And now it's a useless brick, says SAMSUNG and that's it.
Brand new one-day old superphone, totally wrecked. I don't even think there are any stock ROM's out there for this thing yet.
I'm a meathead.
I'll try reinstalling the firmware again that I did before, maybe I'll get lucky.

Nope, still nothin'.
So now I'm going to do something really crazy. Somebody on the interwebs says you can flash the SGH-1317M with the stock rom for the GT-N7105. Says it's the same thing except it's the international version and that it's even better.
I went to samsung-updates.com and searched for the Note 2, and sure enough, it's on their list of ROMs for the Note 2. So I'm downloading the GT-N7105, and I'ma gonna install it, unless someone here tells me different!

Don't do that. For one, flashing a ROM for a different device is virtually always Detroit Brick City. Two, the guy's got two whole posts. Don't do it.

Any rom in our dev section should fix you try clean rom ans stop using titanium vackup. Why are you debloating roms when devs did it for you already and obviously you see you have no clue what you're doing?

[/COLOR]Lol... that didn't work at all... I thoughtbthe links would copy over... look in the android dev section theres a rom there for you. .. 8)

Just flash any rom in the android development section usinf twrp or cwm, it will rebuild /system and fix any issues. In the future dont delete or uninstall system apps, just freeze them if you think yiu dont need it. Freezing stops the app from running ans taking up any cpu or memory so its almost as good as deleting (it still technically takes up space but this phone has plenty of space) with nine of the dangers. If something stopped working like play store, youvcan defrost the apps yiu froze easy enough.

Yes we promise lol and dont freeze or delete anything just leave it to the devs and only download stuff from this forum i317/i317m

Sadly, failure
I downloaded CleanROM Lite 1.0.zip, put it on the SD card, and used Clockwork Recovery to install it. The installation went without a hitch, but trying to boot the phone, all I get is the SAMSUNG logo still. So I did a factory reset, wiped the cache, wiped the Dalvik cache, and did "fix permissions", but it's the same.
So I'm downloading the other ROM ("Stock Root - De-Odex") and will try that presently.

These roms take a while to boot how long did you wait. Look you didnt break your phone from deleting apps just flash the rom and wait it will boot. Remember these roms are 750-800 mb worth of data to boot not 250mb like aosp roms, takes few mins to boot

You might have been right. I'm so used to it just freezing up that maybe I wasn't patient enough and just assumed.
But it works now! I flashed the Stock ROM, and it booted up with no problems. Then I flashed the lite one again, and it works too. So now I'm going to try the other ROM on the dev page, see how it looks.
And it's still rooted, so hooray!
Thanks for all your help.

you REALLY need to do ALOT more READING, and ALOT LESS Flashing...

Note 2 constant freezing issue

Hi everyone,
I've searched everywhere for a solution so please help!
Basically i've had my note 2 for around 3 months and it keeps freezing (so frustrating).
Surprisingly this happend on stock before i even rooted or anything like that.
I remember installing some game from the app store that started the freezing but i re flashed it on stock and this was ages ago. I went to samsung and they flashed it but they said that they dont know what it is. Without sending my baby away i'd love to get this fixed.
I've tried rooting, unrooting, different roms, clearing all the cashes.. apps to reduce lagg (incase it was something inducing it).
Im really clueless where to go with it..
(Freezes up to 5 times a day)
(On 4.1.2 because of custom rom)
(On Stock rom now trying to fix but still on 4.1.2)
Thanks for all your help in advance!

Hi Broky
Its on stock at the moment and i've taken my case of because i thought it might be that before....
When i was in the samsung store it was flashed to the stock and i opened skype after the flash and it froze....
Dont know if this is much help?
Thanks!

Try super wipe script by zoot.
Then flash stock rom.
Don't tell it samsung or google account.
Play around with it like browse or do anything. If it still freezes then I am sorry then brockyneo is correct.

Could be a faulty ram chip. Or flash chip. I don't think check disk works on flash drives. But if it was a hard drive that's be the fix.

ya it shouldnt freeze if its been flashed back to stock rom,especially through odin as it near bullet proof
maybe try what UtkarshGupta with the superwipe and try again with a stock rom
if not then you maybe looking at a faulty unit :crying:

What firmware do you have? 4.1.1 or 4.1.2? If you are on a safe kernel (latest 4.1.2 for example) you could try "Dummy File Generator" from Playstore. (there are many reports with succesfull fixes on freezes.) Or, better, take a look at this thread, everything you want to know is here: http://forum.xda-developers.com/showthread.php?t=2133401

Hey legendberry! Did you fix your problem? I'm having the same issue on a stock rom. Resetting and wiping didn't help so I sent mine for repair but it got sent back to me unrepaired and the issue is still there

I have stock note 2, running 2.1 worked flawless since day 1 (was first release in France). Last 2 days been freezing. Have freed up space in internal and external sd. Still happens. Removed some apps, still happens. Reboot, sometimes it works for while then locks up. Very frustrsting as this is business phone.

......

I am in the same situation, because my Note 2 in the last few days has been freezing with maxed out cpu (as reported by the Cool Tool app).
I am now in the process of wiping everything and restoring in the feeble hope to overcome the problem.
Edit: i have wiped everything by formatting with Odin and reloading firmware, then restoring nandroid backup. So far so good, almost 24h without freezing.
Edit2: 2nd day, started freezing again 0

Same problem here, since 2 days my Note 2 freezes all the time, sometimes with 100% cpu load. Sometimes I can use it for a couple of hours, sometimes after reboot it freezes instantly. :S
I did a factory reset (stock 4.1.2), wiped everything but still the same issue...
Very, very frustrating!
To users above: When did you get your Note 2? I've had mine since Oct 10, 2012.

R: Note 2 constant freezing issue
Me too, phone bought in October 2012.
Today I flashed latest Italian firmware, MB2, and started over. No freezes. Even filling sdcard with dummy file generator, which in previous firmware (French MB2) gave several freezes.
Ok.
Then restored nandroid, data partition only, and wiped cache and dalvik. Lots of freezes again, device almost unusable.
So I thought what's the difference? When freshly flashed phone had Touchwiz, while after restore had Go Launcher.
Uninstalled Go Launcher. Bingo.
No freezes anymore so far.
Weird, uh?
I'll report how it behaves in next hours.
Edit: it was go launcher indeed. It's been updated for a reported crashes reboots problem. Now my device is rock steady.

Currently having the same issue. What i had done is cleanwipe and restore to factory setting (4.1.2).
Just the moment i finished setting up, the problem occured.

Unbearable Lag on EVERY custom rom

Ok so here's my situation, Last night i performed a backup of my current rom (AOSPA) and when it finished and booted back up my phone became unbearably laggy. This isn't a rom specific problem either because i've tried wiping and clean flashing several other roms that hadn't given me this problem. I've also tried the Lagfix (fstrim) app which doesnt seem to work (Gives an error message then grays out the button and says "Not Supprted").The only way to get rid of this lag is to completely unroot and install 4.0.4 then root again. I had this problem about a week or two ago also. i was just wondering if anyone else has had this problem. If so, Is there any way to get rid of it without unrooting? Thanks In Advance

have you tried to flash the stock image from google? I had the same issue for my nexus 7, flashed factory image and all lag is gone, feels like a new tab again.

So going to atock 4.0.4 fixes the issue correct? Id suggest wiping the entire phone system and all. If u search my profile i have a one click flash to stock tool. It deletes everything but will put u back on 4.0.4 the day it came out of the box. I think ur issue lies somewhere in storage.
If u have the gsm nexus then uncheck the radio flash boxes if u decide to use my tool.
Also my tool contains the stock image from google. No hackery of any kind.

Thanks for your help. I seriously hope this is the last time it happens. I think I have narrowed down what the problem is. It seems that whenever my internal storage gets below 1gb this happens. I believe that was when it started last time. I guess I'll just have to use less internal storage to keep my nexus fast.

I guess you still have the lagfix-issue. Normaly LagFix should be able to recover your speed. I sometimes have a problem with lagfix not getting the root-permissions from the superuser fast enough so it considers your phone unsupported. Try this:
1. start LagFix and click on Run!
2. Grant root-permissions to it and save the decision so superuser will not ask again.
3. if LagFix fails with the unsupported-device-error go on...
4. quit LagFix and clear its DATA from app-management
5. start LagFix again and click on Run!. Not it should run OK without asking for root!

Clearly CPU overheating is the issue. I too had overheating issue. I too did flash several ROMs. But, it all started with DN3 ROM. After that no matter what I flashed my CPU would heat up quickly.
Issue is closely related to kernel. It happens due to migration from one ROM to another. In most cases the wipes and installs are clear. But sometimes things go wrong unexpectedly.
You can try some solutions:
1. Stop indexing service with Titanium and check.
If warm again,
2. Power down the phone, remove SD card and wait for device to cool down. Restart and check.
Still not then
3. U will have to flash stock recovery on your device and do a wipe/ factory reset from the menu. (Of course u will lose all the data on internal SD card). Check for at least 2 battery recycles.
If not then,
4. Backup everthing EFS, CONTACTS,etc and flash stock rom via pc odin. When phone reboots and reaches language screen. Power it down, go to recovery and do a wipe/ factory reset.
This should surely solve your overheating problem.
If not, it might be a hardware issue.
