Hello XDA
I tried updating from Cyanogenmod 10.1 to 10.2 nightly( I understand it was development), and my phone froze on starting apps (cleared cache), and never booted. Next boot it stayed in a boot loop, so I decided to restore from a backup. I wiped my system and proceeded to restore both system and boot (didn't want to override my apps so I unchecked the rest), and then cleared caches again to be safe. Now it is in a bootanimation loop and has been so for 5+ minutes. What could possibly be the cause of this? Is there any way to fix this without having to wipe my apps and data (I have a backup of system, boot, android_secure).
Thanks,
ccrama
Did you flash the boot with fastboot?

No, I updated with the CM updater. It did all the installing/wiping, but got me stuck in the original boot loop. Now, I used a backup to restore my old system files (from 10.1), but it is still in a boot loop D:
EDIT: I'm on TWRP and the backup was a nandroid backup
Give it a try to flash boot with fastboot. Your can extract it from your backup.

I tried to flash a cm10 rom and i did thought i flashed the boot.img separately as i read you have to but it was stuck booting for at least 25 min so i gave up with that and tried to restore from a backup i made with twrp. I restored from the backup and tried to reboot but nothing happens, it shows the htc screen and then turns black and thats it. I can go into bootloader and recovery but im not sure what to do to get back. Should i try a ruu?

Maybe it was a bad restore? or a bad backup? You could try restoring from your backup again.
Or blaze on and see if you can get CM10 up and running.
Did you wipe /cache/dalvik/system when coming from stock (before installing)? I've seen situations (on other devices), Where I've had to delete the /data partition as well, I'm not sure why it wouldn't boot, but it refused to get past the CM load screen until the /data partition was wiped. If it's a new phone and you don't have too much on the sdcard, this might be worth trying.
Once you have TWRP flashing ROM's shouldn't be too bad, it's just the "fastboot flash boot boot.img" that catches people out usually.
you still have to flash boot.img separate before/after a twrp restore.
Grab the boot.img from a stock rom
Wipe cache/dalvik
Factory reset
Bootloader, fastboot usb, then fastboot flash boot boot.img
Then restore the backup
Thanks everyone for the responses, I was able to get it working after trying a few more times and wiping everything. Not sure why it didnt work earlier but all of a sudden after trying it just worked.
I saw that TWRP was updated to 2.3.3, so I first made a backup of boot and recovery partitions in TWRP and named the backup "recovery" with compression enabled. I then rebooted system to use Flash Image GUI and the device hung at the boot animation. I reflashed the kernel in fastboot, wiped cache and dalvik, and it still hangs. I can still boot into recovery (never actually updated). Do I need to reflash the ROM? Was running King Kang and b6.
Edit: Well ended up doing a full wipe restoring rom and tibu. Still no idea what happened though. Making a backup shouldn't mess anything up like this...
HTC EVO V/3D. im stuck in boot loop, im on pac man rom and my phone ran out of battery and once i put it to charge and tried to turn it on it boot looped. all i really want is my data to restore but when i wipe all flash the rom and restore data it boot loops again. i didnt have anything on the data or system that would cause a boot loop. is the any way to restore my data another way from my 4 ext recovery backup. or is there a way to fix the boot loop?

Boot loop is probably caused by offline charging, the ROM may have a bug with it, one solution is to prevent the phone from running out of battery and plug it right away.
About the data restore from the 4 ext, you can use CWM recovery 6.0.2.7 which has support for SD card extensions, it will detect your partition and will manage your data, and all your apps linked to the partition.
You could try this. I use a gnex toolkit posted on xda. It saved me from a couple of boot loops.

Sorry if this has already been asked; I tried searching, but I couldn't find anything.
I'm running Exodus version 5.1-20150911-NIGHTLY-bacon, TWRP 2.8.6, Exodus stock kernel
I'm trying to update to a new nightly, but I always get stuck in a bootloop.
Here's what I do:
Reboot to recovery
Nandroid backup
Wipe data, system, cache, Dalvik
Flash the new ROM (I tried COS 12.1 once, but it didn't work; I mostly try flashing the latest Exodus nightly_
(sometimes) Flash xposed-v74-sdk22-arm-by-romracer (it doesn't make a difference if I don't flash it)
Restore only the data from the last nandroid
Now when I reboot I'll just be stuck in the boot animation or I'll be able to pass the animation and I'll just be stuck in a loop setting up the apps.
If I don't flash xposed, but still restore the nandroid I'll boot up faster, but I get System UI has Stopped and then the phone goes into a boot animation loop
If I don't restore the nandroid it works fine and boots up way faster.
How can I update while keeping my app data (my xposed data isn't that important to me if that'll make a difference)?

Why are you bothering to wipe if you're restoring your nandroid data anyway? Restoring the data is just canceling the wipe you just did. If you want to flash and keep your data just dirty flash the ROM update (a dirty flash means installing the zip while only wiping cache and dalvik cache).

I didn't realize that.
Edit: How do you clean flash and keep your data?

You can't, that would defeat the purpose of a clean flash.
hello, I have an issue..
I create complete rom backup with trwrp, but..
When I need to restore this backup , I restore it in TWRP, then reboot to OS but it NEVER boots up. It just stucks on white Sony logo and thats all
I have tryed wiping everything before 4restoring, and not wiping anything before restoring.. but my rom backup never boots up..actually it doesnt even start to load system OS never gets to bootup animation just stays on sony logo.. also tryed switching boot slot from A - B with twrp after restoring but no go.. please any ideas?
Also If I may.. have a second question regarding TWRP, when I install in system TWRP app, it never detects that twrp is installed .. maybe because xa2ultra doesnt have recovery partition or ? any solution to get twrp app to work when system is booted up?
no ideas why rom backup can't be restored? need ideas/help please..
is there any other way to make flashable rob backup excwpt in twrp wich doesnt work?
