Constant boot loop when trying to root...

I have been trying a number of different methods to fully root my EVO, yet for the life of me, cannot get a new ROM to flash properly. Each time I try flashing a new ROM, I end up in an endless boot loop & must go back into my SD card & rename my stock ROM back to 'PC36IMG.zip' in order to get out of it. I have heard that this sometimes happens from not erasing the dalvik cache, yet I have tried that too & still no luck.
Does anyone maybe have some pointers on why I may be experiencing this issue each time? Any input would be greatly appreciated! Thanks!

you rename your stock rom to pc36img.zip? What is a stock rom? Where did you ever read to do that?
I don't know what directions you read, but Something is very wrong.

Well it's A stock ROM that I picked up during the many different methods of rooting I have tried... For some reason, that has been the only way to get my phone to boot after trying to flash a ROM to it...

Most of the time if you wind up in a boot loop after flashing a new rom it's because you didn't wipe data, cache, and dalvik cache before flashing.
If you are using clockwork recovery it may be your problem. It has been reported to not complete wipes fully leading to post flash boot loops. Try amon-ra recovery.

Galaxy Note II Rogers Bootloop (HELP!!!)

I tried installing a rom last week on my Galaxy Note II (Rogers), i followed orders (this isn't my first time flashing roms), and it has been stuck in a constant boot loop.
I've tried everything, wiping cache, factory reset, tried to flash different roms, etc....
I am a mac user (which means Odin isn't an option).
If you guys have any suggestions on how to fix this it would be greatly appreciated.

What rom were you on and what rom were you trying to flash originally? Also what recovery are you using? Need a little more info because usually wiping caches dies the trick. Provide a link to the rom you were trying to flash of your can.

This is the rom, i was using CMW to flash it, then it made me switch to TWRP (think its called that)......hope that helps.

Sorry I can't be of more help aside of redoing the installation of your recovery and redownloading the rom ( bad downloads happen) and making sure you do all the wipes (cache, dalvik cache and factory reset). If none of that works I'm sure someone more knowledgable than myself will chime in.

I've never run into a bootloop problem myself, but this might help you out :

Good luck

Have you had any luck with this yet? I've been unable to get my phone back up.

Put another ROM on an sdcard. Take your battery out then press the button combo for recovery mode before you slip your battery back in. Then it'll force download mode. Reflash the new ROM after full wiping and you should be good.

Definitely a bad ROM. Run a MD5 checker against it prior to copying to the SD card. Note: your SD card could be the culprit.
If you have a recovery installed, ensure you WIPE everything, Fix permissions (i'm on CWM) and reflash the modem and carrier files POST rom install.
I experienced my first boot loop yesterday but I was able to recover from it thanks to a little common sense and patience. :fingers-crossed:
Good luck!

first of all, don't freak out, a bootloop isn't the end of the world. Sounds like it was a bad flash.
ppl above have obviously told you to wipe caches, and all that stuff and if it hasn't worked then you are still down and out.
I would suggest you get yourself into recovery - not going to explain that here as you said you were able to flash other roms and it didn't work and try flashing your nand backup - hopefully you have a nice clean backup from before you flashed. if so, clear caches, etc and then try flashing it it should be back to at least working.
your nand backup will have all your stuff in it as you would have had to backup from recovery, which means you'll at least still be rooted. you can then go ahead and get another rom - check the md5 and flash it

[Q] Am I missing something?

Short Questions: when I flash any ROM, besides official AOKP, my phone goes into bootloop. I'm using CWM. I do a factory reset/cache etc. then flash the new ROM, i.e. stock koodo, but they all just boot loop.
Long Story: I used to have a samsung galaxy ace, and I followed the same persedure, with CWM, and it always worked. I used CWM on my tablet, but the other touch recover has given me problems and never really worked correctly, it wouldn't even install properly. I prefer CWM. From searching around, there is some super wiper, or infamus whiper that clean the phone properly from the recover before flashing. I'm not sure if we're supose to use that before I flash a new ROM, maybe that's why its bootlooping?
What do you do before you flash a ROM? I know the ROM OP have instructions, but they end in a bootloop too.

I believe you have to be more specific if you want to get help, like the version of CWM, ROM you are trying to install and steps you are taking to insall the ROM.

Click mounts & storage, format system/data, yes. Then do all your other wiping like data and caches. Then flash ROM followed by gapps.

You are not formatting system before installing a different base(ROM).
If you format system, data, cache, and delvik you should be good to go.

[Q] "gapps stopped" loop after CWM restore

Hi,
I was frustrated with the delay in T-Mobile's release of KitKat for the GSIII, so I decided to root my phone last night in order to try flashing CM11 on it. Rooted my phone with Towelroot, installed ROM Manager and CWM, and created backups on Kies and through CWM. Then I proceeded to do data wipe/factory reset, cache wipe, and /system format. Tried to flash CM11, but got a status 7 error.
I freaked out, so I decided to restore everything from the backup I'd created. Restoration seemed like a success, but now I get the error "Unfortunately, the process com.google.process.gapps has stopped" in an endless loop, and it prevents me and any apps from doing anything. I tried clearing dalvik cache in recovery, but the problem still persists. Read on a few threads that I should flash to stock firmware via Odin, but I'm currently on a macbook, so I can't install it.
tl;dr - Prepped to flash CM11, reached status 7 error, got freaked out, and did restore via CWM, only to get infinite loop of gapp crashes. No access to Odin or PC. Not hard bricked or soft bricked, but essentially useless phone. Help? );

if you can still get to recovery, download latest gapps and flash that

Did you factory reset before or after you restored your back up?

Yeah, I've tried flashing gapps--no avail.
And yeah, I did factory reset/data wipe, cache wipe, /system format 3x each before attempting to restore. Was that wrong? /:

Try to factory reset again

If I'm not mistaken, there is some device ID that will change each time you flash a new rom. It may be something to do with this ID not matching the one in the restored data. Purely a guess but seems logical to me.
Anyway, factory resetting will most likely solve this for you, but I wanted to add that except in certain circumstances, you shouldn't ever manually format /system. (and one format on any partition is sufficient. There shouldn't be any need to format multiple times). If you format /system, you are wiping the O/S off of your device. Then what happens if you have problems flashing a rom, or firmware? I've seen it happen many times and I often end up spending a couple of days working with them just to get the thing to boot up again!
When you flash a rom, the first thing it does is format /system. So there is just no need to do this manually. At least if the rom fails to flash (such as failing the assert checks), youll still have something to boot into. Hope this helps in the future!

I have had the exact same issue. I have a Samsung note 2 N7105. I rooted made a backup in CWM and flashed ditto n3/s5 rom made another backup in CWM. No issues. Got a bit cocky seen as it was my first time doing anything like that. My next adventure was to try a custom kernel (agni). This didn't go so well, so I tried to do a restorw to my working backup of ditto n3/s5 rom through CMW. restore went smoothly and the phone booted. once I opened the lock screen I got the gapps error as described. I had to do a factory reset to get the phone working and then re-flashed ditto n3/s3. I've since flashed other roms and when ever I try to do a restore, I get the issue described. Note I am using the latest CWM. I putting off flashing and trying any other ROMs because of this issue. I do love dn3/s5 but id love to try others. Anyone can help it would be appreciate.

Issues flashing ROM

I'm having some issues flashing any ROM. TWRP will not wipe data, or internal SD
For some reason, when I go to wipe data and factory reset, TWRP will say it was successful, but nothing ever gets wiped. It will only wipe system if I choose to. I've gotten a ROM to flash but when it boots up, all of the old apps and user data are still there and it makes everything crash. I've gotten into settings to do a reset, it reboots into recovery, runs the script, and still nothing wipes.
What I have tried:
Old TWRP, newest TWRP
CWM (seems to wipe but it won't get past the note 2 screen after flashing anything)
Wiping with CWM, flashing TWRP, then flashing a ROM (still loops after the note 2 screen)
Is there a terminal command I can use in TWRP to manually wipe things?
Thanks for any help I can get, I've flashed so many phones I can't remember but I've never had this issue

Maybe flash back to a stock ROM, factory wipe using stock recovery, then flash TWRP?

Well when it bootloops t the Note 2 screen, I have to flash a ROM with Odin to get it working again. I've flashed a stock ROM with Odin, flashed TWRP with Odin, tried the wipes and it never wipes anything... I'm lost...
Isn't there a format function in TWRP that is seperate from the factory reset or advanced wipes? I was also trying to find a terminal command to type in the terminal in TWRP... I'm a little stumped...

I'm sorry, I read that too fast... That may actually work, wipe it in the stock recovery, and just don't let it boot into the system before flashing other stuff... I'm gonna try that out... Thanks man, I'll post back about it...

Since you are flashing the phone with Odin, is it a stock 4.1.1 ROM you're flashing? Which custom ROM are you flashing to the phone?

The stock ROM I used is I317-ODIN-UCUCNJ1-Stock without the booloader packaged in, I'm still on the old bootloader. It's 4.4.2
The ROMS I've tried to flash was
Cyanide (Error 7, says incompatible data, please wipe the phone)
Resurrection Remix (Error 7, says incompatible data, please wipe the phone)
Latest CM10 Nightly
I got CM10 and Resurrection Remix to flash a couple times, but the phone boots and all the old apps and data, including the AT&T ones are still there, and the system keeps crashing. Then I change the recovery to CWM because it seems to wipe, change back to TWRP, flash the ROM and gapps again, but it bootloops at the Note 2 screen.
Should I try the 4.1.1 ROM and CWM? Whenever I'm going from a stock TW to non-TW I like to format everything, data, cache, system, and internal SD, but of course TWRP won't wipe the data or the internal SD.

It's probably because the bootloader and modem are too old for the roms. Recent roms will need updated bootloaders.

Ok, I had some more time to mess around with this today and figured it out. I feel kind of dumb but oh well, I got it.
TWRP was already loaded on, so I went to messing with it again. The 'Swipe to factory reset' was not wiping the data, and there was the 'Format Data' button right there in front of me. I did the factory reset, format data, rebooted recovery, wiped dalvik, cache, and system, then flashed the ROM and everything booted up just fine.
Thanks for all of the help!
