[Q] Constant Bootloops ARRGHHHH

Ok, so here is my story:
I rooted way back in July right after I got my Evo, so I started on Android 2.1. I flashed and used OMJ's ROM for quite a while until I discovered Cyanogen mod, which I switched to after trying OMJ's 2.2 ROM.
I used CM6 for a long time, eventually flashing some nightly builds, culminating in nightly build number 140. At some point in this process, I started having real trouble with bootlooping CONSTANTLY (and I couldn't even make a nandroid backup because it would reboot inside the backup process). I eventually got it to stop bootlooping after many many reboots and wipes (full wipe, cache wipe, dalvik wipe) and restarts and got CM to boot.
I just now flashed CM6.1 and started getting constant bootloops again. I assumed it was a problem with CM, so I decided eff it, I'm going with a different ROM and downloaded Calkulin's EViO 1.5 rom to try, but it can't boot either.
I can get to the android screen, which displays no signal, then it reboots. I can't get out of this cycle. When I was on CM, I had issues with starting up - I had to hold down the power button quickly and press airplane mode, then it would reboot again, but it would come all the way up. Then once it was fully booted I could disable airplane mode and it would stay online. After that point, I just decided never to reboot the phone, but this is a huge problem that I can't figure out how to fix.
I have tried wiping using Clockwork and Amon Ra, but neither makes a difference.
Any help would be GREATLY appreciated. Thanks!!!

it reboots while making nandroid? So even if you hold vol down + power and go to the recovery from there it is rebooting?

Correct, I hold volume down + power to get into recovery, then choose nandroid and backup, then while it is creating a nandroid backup, it reboots.

Does anyone have any ideas? At this point, I have no clue what to do, and I can't boot into any ROM.

If you Google it you'll see its an incredibly common problem not just with those of us who have modded our phones but those with stock roms who have never done so it happened to me when I originally flashed cm6 to my phone as well but it eventually fixed itself if you can get it to boot try factory reset it may help

Factory reset just wipes your data using your recovery doesn't it? Either way, I've tried that, and no dice.
I mean, I guess at the very least I could try to bring the phone into Sprint... is there a shipped RUU I can flash so they can look at it?
edit: found the latest RUU (http://forum.xda-developers.com/showthread.php?p=8474707)
I'm gonna try this and see what happens.

same problem. no solution. i am now fully bricked, aka i reboot before i can pull down lockscreen (rom changes, unroot, nothing works) return before it gets so bad you cant unroot.

No good man I hope you got insurance

Ewe, thats no good. I would use the ruu but Do Not Use The Newest One. You will lose root and the new 3.30 people are having trouble rooting

same thing happening to me. Stuck in bootloop now, started out as just a random reboot that would boot than reboot than hold for a while. Right now im completely stuck in bootloop =(.
Is there a way to put a stock rom on my phone with just booting to recovery?

These sound like hardware issues but if your recovery is working fine then it may be something else. Did you try the RUU while in the recovery?
Just don't use the newest one

I was finally able to get to a point where I could get it to boot - here is what I did.
I wiped everything using amon ra's recovery, then flashed the latest cyanogen mod from here: http://mirror.teamdouche.net/get/supersonic/update-cm-6.1.0-RC1-Supersonic-signed.zip, then when it booted, it would get constant bootloops, but it would get to the home screen for a few seconds each time.
You have to click through the intro menus reaaaallly freakin fast so you see the desktop with the live wallpaper. DON'T sign into a google account. It will probably bootloop again, and if it doesn't, quickly hold down the power button and select airplane mode. If it reboots again, it will power up completely successfully in airplane mode. Then make sure you're in an area of good signal and disable airplane mode until you have 3G, and then sign into a google account. If it starts bootlooping again, quickly hold the power button and press airplane mode - you can always boot successfully in airplane mode for some reason...

It could be hardware related, but I'm not 100% sure at this point...
The reboots seem to be correlated with signal strength. If I have 1 bar of signal (in CM, so not cell signal), it will reboot before it gets to 3G.
Also any flash on a website reboots the phone for some reason. I don't know if that's common or not.

Phone restarts and won't turn on

For the past several months my phone would restart randomly when I used 3G, GPS or sometime just from heavy usage. It would turn off, boot to the white HTC screen but then the screen went black and it would vibrate 3 times and a led would blink. At that point the only way to turn it back on was to pull the battery and power on (although that usually didn't work until after a few tries or letting it sit for a while).
It has done this with both CM7.1 and decks 1.3 and with the Tiamat 3.3.7 & 4.1 kernels. I flashed Mason .14 on Tuesday hoping it might fix the problem. It did at first but after 24 hours it was back to restarting randomly, only this time it was worse. I was also getting a lot of force closes and it would restart even it was sitting unused. It would take hours until I could get it to successfully boot again. I attempted to do a full wipe and install CM7.2 yesterday only to find out I can not boot into recovery, attempting to do so causes the phone to turn off (I tried both through holding the power button and selecting recovery and through the bootloader).
As of right now my phone will not turn back on at all (going on 4 hours), I've had it successfully boot twice only to immediately turn off, other times it gets stuck on the white HTC screen.
I am still able to access the bootloader so I'm thinking my best option may be to place a PC36IMG.zip on my sdcard and see if I can't flash back to stock and then load CM7.2. My concerns are a) not sure if that will even work b) if the phone were to turn off in the middle of that would it completely brick my phone?
Sorry for the long post but I just wanted to provide as much info as possible. Any thoughts/suggestions would be greatly appreciated.

Can't boot into recovery? Have you tried reflashing your recovery? Get a PC36IMG file of your desired recovery (preferably amonRA, or drellisdee) and flash it thru bootloader. It only takes a second to flash, so I wouldn't be too worried about it shutting off while flashing it.
That's all I got.

Unfortunately that doesn't work. Flashes the recovery just fine but I still can't access it. I did manage to get my phone to boot into android after trying, not sure if that's a coincidence or not.
So I'm left with my original option, flashing a stock PC36IMG.zip. Also this might be a dumb question but can I rename anything PC36IMG.zip and flash? If so I could just rename Calkulin's format all, flash that and then repeat the process with CM7.2. Anyone know if this will work?
Edit: Should probably also ask if anyone knows what is causing this, is it a kernel issue?

Just a thought, maybe a bad battery or a bad usb?
Did you try the battery in another phone? Or, another battery in your phone?
Sounds like it may also be going for the reboot of death... If your recovery is corrupted and getting random reboots, maybe your internal storage is going bad...

I was able to flash back to stock and it is still having similar problems. Turns off during any sort of data usage both 3g and Wifi. The fact that it has happened on multiple ROMs, multiple kernels, and multiple radios makes me think it is something hardware related. I guess I will talk to sprint and see what they can do.
BTW does anyone know of a method to flash an S-On zip file as a PC36IMG in the bootloader? I am still S-Off because I can't go into recovery to flash.

Well after going back to stock but still being S-Off I decided to try reflashing Amon_RA and I eventually got it to boot into recovery. It was similar to booting into the OS, I just had to pull the battery and wait 30+ mins before trying and then boot into bootloader and select recovery. It was a PITA since I needed flash a couple things but it worked. Got it back to S-On and took it to Sprint. Of course they didn't bother checking for any of that haha but I was able to get a replacement EVO.

stuck on black screen after flashing rom

I was running the new version of Hyperdrive until the mms stop sending so I decided to go to Goodness. Originally I could not get any rom to flash from the internal or external memory, so I pulled the sd card wiped everything and reinstalled my backup of carbon from trwp. After I confirmed the phone was working properly , i downloaded and placed goodness onto my internal memory (ext sd is not in right now) , and flashed no problem. Now the phone boots the Samsung logo, the goes into the Goodness boot animation, then goes black. I left it sitting for 30 min and nothing. Did a battery pull and nothing. So finally, I tried to get back into recovery mode and i cant. I hold volume up+home+power and the phone displays the blue script that shows recovery, then the samsung logo, then boots right back into the Goodness boot animation. How can I get back into twrp? Ive searched high and low for answers but cannot seem to find the answers to my problem. Thanks

Can you get into download mode? If so, reflash your recovery and try again.

Did you wipe in between flashes?

between hyperdrive and carbon I did a full wipe. Between carbon and Goodness I didnt. i figured I would be ok since I installed nothing but the os and gapps. I had done it other times with no problems and figured this time would be the same.

Well I was able to unroot and re root my phone again. To answer the question though the boot animation would go on for 20-30 seconds and then the screen would stay black. No noise, no touch control, no indication that the power was on. When placed on the charger, the led wouldn't even display.

So is it all working now?

Make sure you redownload it, just in case it was a bad download.. you never know. I know it is time consuming but worth it.

Look it up.

there have been a few cases where for some reason the boot animation wouldnt start although the device was booting. simulating the " black screen ". this also has happend to me several times on a " first boot "......id try letting it sit for a few min. if it doesnt finaly boot, then just whipe whipe whipe.....reflash..and possibly redownload and reflash...

Wrong forum, wrong thread. Go start a new thread in the appropriate forum.

I foolishly got myself into a pickle, tabpro 8.4 stuck in bootloop into recovery

So I decided it would be a good idea to wipe everything including data and internal data etc using my twrp recovery on my tablet 6am in the morning so then I could do a fresh rom instal over adb. I fell asleep in the middle of wiping, woke up at 3pm (15 minutes ago) to find that the battery is dead. Plugged in the charger, tried to boot it up. No matter what I try I cannot get it to boot into anything else other then recovery, which is broken because it just flashes me the twrp logo, goes black then flashes twrp boot logo over and over, I can't even shut it down properly now. I've tried holding differrent button combinations etc and nothing works, i just get the bios logo (samsung logo) then back to the twrp logo loop whenever I try something.
What can I do fix this? I did have the android sdk btw, just realized I switched hard drives and have to download it again, I'm getting it right now.

I would first let the battery fully charge if you haven't already.
Then download a recovery flushable rom, i would pick one of the cm based because it's the smallest and this is to get you back. Load it onto your external sd card and flash as normal.

It's been on charge for 3 hours still trapped in this boot loop, it can do literally nothing else, not turn off or anything lol.
How do I flash any rom? I can't get into recovery, it's just boot looping over and over and not letting me do anything.
The screen is black for 5-8 seconds, then it will flash the twrp logo for a split second and go back to being black and repeat.
Holding the power button (with or without ANY combination of holding down volume buttons) all do the same thing, just reboots it into recovery which starts the above boot loop again.

Anyone know a way to force it out of a boot loop or a way to reset or flash the recovery or rom while its in the current state it is in?
Lol would really appreciate it if someone could help me out here.

So I went to go try what try mgp53's suggestion. Saw that the tablet had died. Booted it up, and i got stuck the samsung logo accept oddly enough there was nothing in the top corner. adb devices showed me nothing was attached to my computer so I just got mad and powered it back on and off while holding down different combinations of volume buttons, and I got into ODIN MODE! Says download, do not turn off target. Awesome! What do I do from here? I don't know what the state of my tablet is because I tried to wipe everything, including what shouldn't be wiped. So I guess I would have to restore everything including recovery.

What should I do from here? I'm at a loss because I don't want to mess it up more.
EDIT
UPDATE 1
I started by using ODIN 3.09 to flash the latest tar of twrp. Boot is still messed up on all accounts accept for when I hold volume up now, so now I can get into recovery again, awesome! Went through the directories through twrp, all the folders are literally empty lol, including where the super user binaries should be which troubles me a bit. Going to go ahead and flash a rom by sideload and see how it works out.
UPDATE 2
Attempting to sideload now. Getting mount errors for E:, unable to fun partition for path /sdcard, so something wrong with my internal storage. How am I to fix this? lol

You can try samobile, but they make you register. Also I don't know if they don't also use rapidgator.
Or maybe you can try this. Grab the cf autoroot tar. Flash that in odin. Then flash the twrp tar and your recovery should have root access letting you flash custom roms again. Just dl a small one like cm.

Ok cool! :good:

Thanks for all the help, got it fixed and runnings after using Odin for firmware, then to reroot, then Odin to flash philz recovery. Then flashed CM, running brand spanking new.

Oh oh, got the same problem here.
I used the guide from rootjunky on Youtube to install TWRP 2.8.0.1 with flashify but after flashing the tablet wont get into recoveryscreen from TWRP.
So i desided to get back to stock recovery and stock boot image (a made backups before) with the intention to flash TWRP 2.7.0.2 like in the video.
But after flashing the stock recovery the tablet hungs in a loop but i can get into recovery.
can someone explaine me haw to get my stoch recovery back? Or boot image? I don't know exactly wat the problem is, boot or recovery. I'm not to good at this.
And srry for my english, i'm from holland

Frozen on Samsung Logo

Hi. I was trying out Blisspop on this tablet and decided I preferred CM11 so decided to restore a backup. After rebooting, nothing turned on, only download mode worked so I just flashed stock firmware using Odin (which I had used successfully previously). Now it boots but gets stuck at the Samsung Logo. I can still get to download mode, but nothing else. I've read that if factory reset in the stock recovery, it'll work itself out but I can't even get to it. Any suggestions? Thanks.

Dont panic really common problem happened to me.
1. Boot into recovery, if not flash one with odin coz your gonna need something...like philz touch or team win or whatever.
2. Wipe cache and dalvik, reboot and wait, samething might appear to happen but it should boot.
Basically ive noticed a few times now on my t805 that the cache wouldnt format propperly and became corrupt and caused this.
I knew this because in the recovery a bunch of errors appeared saying couldnt acces log from cache/blah zt each time i navigated the menu of revoveryand so i wiped cache and they stopped
Booted and viola...if you see any other errors in recovery tell us here.
Good luck m8.

The problem was that I couldn't even get into recovery. But found thread on xda that mentioned if you turn off the tablet from download mode (pressing power and volume down) then you can use the normal three button method to get to recovery. And then yes, I wiped everything I could and it finally booted back up. Thanks for the help mate.

But found thread on xda that mentioned if you turn off the tablet from download mode (pressing power and volume down) then you can use the normal three button method to get to recovery. And then yes, I wiped everything I could and it finally booted back up. Thanks for the help mate.
