My phone will currently not boot bast the CyanogenMod boot screen.
I flashed my phone several months ago to CM10.1 It was the update that patched the "masterkey" bug. I have been using it daily since then with no problems.
Today, I turn my phone on, and it just hangs at the boot animation.
There were no significant changes since the last time it was powered on. I think I installed McPixel from the humblebundle, and uninstalled a game from the playstore called Krog. No setting changes of any significance.
I've tried booting into safestrape and deleting both the cache and the dalvik cache, neither has helped. My stock rom still loads just fine, but i had factory reset it quite a while ago. I do have a backup of the rom from about 40 days ago i can try restoring, but i would love a more nondestructive way to fix this.
Try booting into safestrap, wiping system, cache, and dalvik, then reinstall the ROM and gapps.

0.o wouldn't that be a LOT more destructive than just restoring the old backup?

Nope. You are not wiping data so all your apps, setting, etc will still be there.
the data itself will remain if you just wipe the system, cache and dalvik cache but be sure to reinstall the latest stable build of CM and gapps for it

ah gotcha gotcha...
unfortunately it didn't work.
for troubleshooting's sake, i went ahead and made a backup of the rom in it's non-working state.
i restored my old backup, it boots just fine.
restored borked backup (tested it, still won't boot), wiped cache/dcache, wiped system, installed cm-10.2-20130821-NIGHTLY-maserati.zip and gapps 20130812, wiped cache/dcache again for good measure, then reboot and waited 10 minutes, still won't pass boot logo.
so i figure someting's wrong with Data right? so i rebooted to safestrap and did a factory restore, then wiped cache/dcache, and still won't boot.
so now i'm going at it the opposite direction. restoring the working backup, restoring just the data from the nonworking backup, then upgrading CM/Gapps
rebooting.. and....
blank screen with full backlight. not so much as a CM logo.
i guess for now i am going to restore back to the old backup, update the rom, and go about reconfiguring, unless anyone has any more suggestions?

Yeah, definitely sounds like something in /Data. Only other possible option I can think of would be to use Titanium Backup. It has an option to "Extract from Nandroid backup". It's under the "SPECIAL BACKUP/RESTORE" options. I've never used that option before so I have no idea how or if it would work but might be worth a shot.

wonderful idea, unfortunately TB crashes when i point it at either backup.
buuut i did find Nandroid Manager * ROOT which looks like it might be working.
if you really wanna see if it is the data or not have you tried to
flash 10.2 or whatever you started out with... then restore -just-
the data to the freshly flash system and then do a wipe of all
said caches... I do that sometimes to get a fresh start on my
os itself.. works pretty well. Just do not restore the cache just
the data part. Or restore with MD5 checking... if it doesn't check
out then you know for a fact that the data partition in that specific
nandroid isn't any good :/

So I flashed ViperRom with no problem after clearing all cache, dalvik, data and system. everything loaded perfectly, I logged into all of my accounts and then re-installed all of my apps and system data using Titanium Backup. After the TB restore, TB recommended a reboot so I did. And now when the system loads, it is stuck on the ViperRom splash screen. I'm pretty new at this, but not a complete novice.
Can anyone offer a solution?

Sometimes Titanium Backup restores something from one ROM that doesn't play nicely with another. I'd do as flex says and reflash then be careful restoring your apps.

Restoring system data is really iffy. You shouldn't do it unless you really need to. If the app has most/all my data in the cloud (i.e FB, email), then I don't bother backing it up.
Thanks everybody for your help. I did clear all my data again and re-flash. Everything loaded just fine, and I was a little more selective when I restored my apps from titanium. Everything seems to be working ok now. I haven't restarted again for fear of getting stuck again, but I'll cross that bridge when I need to

Try being more careful on what you restore from Titanium Backup. Personally I only backup and restore games + messages + contacts every time I wipe my device.
Alternatively, if you have SuperSU installed, make sure to try flashing it from TWRP from this link. Just telling this to you because most of the booting problems are because of SuperSU atm.
Hi,
somehow the software of my galaxy note got damaged. I didnt install new firmware or anything. i just wanted to shut it down but i think it freezes already there. so i took the battery out. but when i start it it gets to the samsung boot anmation and crashes and restarts again.
i can reach the phils kernal and also bootloader. i hope i can do a custom flash to fix it without that i have to wipe it and reinstall anything. which part i have to reflash to fix that?
if you can reach the recovery, then make nandroid backup and wipe data and cache and dalvik and finally restore your cache and data (or you can reflash using odin and then restore data and cache).

Thanks! Tried it but I think the backup wasn't created correct. I couldn't restore data and cache.
well I used a some months old backup. had to update a lot and to do changes but it works now.
so I will create an actual backup now.

Hi,
using CWM recovery, I restored a backup. Everything seemed ok, but the phone didn't go past the cyanogenmod logo.
I tried wiping cache, dalvik, and re-restored. Still nothing.
The only way I've found is to wipe the data; this way the phone started, but obviously it's like a brand new cyanogen install (it's not a restore...)
What went wrong?
Anything I can do???
I want to know why restoring the backup didn't work; I didn't get any error messages during backup or restore.
How can I trust the backups???
hi all, i made an xda account because i really cant understand whats going on with my phone
HTC One M8 running Android 6.0 (rooted)
so after rooting my phone, i proceeded to install xposed.
i flashed the zip - no problem
i installed the apk, and after choosing 4/5 modules that i wanted, i went ahead and enabled them all and rebooted to activate them.
this is where the problems started. my phone booted, however it kept on flashing a screen with the deafult One M8 wallpaper at me. after a few seconds, it came up with an error "com.android.systemui has stopped"
not sure what was going on, i went to twrp and directly restored my nandroid backup, but after waiting for 15 mins, i realised my phone was in bootloop, so i went back to twrp and did a factory reset and restored my nandroid. but again, it went into bootloop. i tried factory resetting and restoring 3 times before giving up.
my phone isnt connecting to my laptop anymore either, but if i need to flash anything i can do it with my sd card.
im not a complete noob but im still learning and ive never not been able to restore my nandroid.
thanks in advance for any help i can get

*. Flash xposed uninstaller zip and try booting your device. Link here - http://dl-xda.xposed.info/framework/uninstaller/
-->> use this» make a full wipe from recovery, then restore nandroid backup.
*.While restoring nand. from recovery, make a full wipe like wipe system etc.. Then restore your nand. Then you're good to go.
thanks a ton for your reply
i already tried flashing the uninstaller - didnt work
but ill try your second method. thanks once again

Hey, the 1st one won't works, Cuz you'd already did a factory data reset, so that's gonna be won't work. And you'd tried restoring nandroid over that, so that's failed.
I hope second one will works.

Deym!!
So, look at the One m8 forums, you'll get the workarounds.
I've found one here - https://forum.xda-developers.com/ht...k-twrp-t3086860?_e_pi_=7,PAGE_ID10,5801529172
@chaitra26, either DL any custom ROMs and flash it via custom recovery [Twrp].
Look here for custom ROMs - https://forum.xda-developers.com/htc-one-m8/development?
Regarding that '' no OS installed'' error, that's common when you try to reboot your device from twrp without installing any system images /ROMs.
FYI - when you full wipe your device and tries to power up you'll get the same warning.
Apologies for duplicating this post but the original forum was apparently the wrong spot for this.
I need either some pointers or a reference to a how-to, if you please.
My Nexus 6 is currently running Pure Nexus 6.0.1-2060821-official, security patch 8/5/2016 with ElementalX kernel 3.10.40-ElementalX-N6-3-20.
I've updated Pure Nexus before through TWRP and all went well, but those efforts never involved updating the kernel too. I've attempted to flash the new kernel, the rom and the google apps, but the phone goes into a never ending boot effort and it's a tussle getting back to recovery mode as it tends to boot loop. The flashes are preceded by clearing Delvik and cache and cleared again after the flash.
Is the order of flashing off or perhaps not enough clearing of other items such as system? Or is a factory reset needed?
Kind of lost on this one and can't seem to string together enough search terms to find help specific to the problem.
Any help would be appreciated.
The kernel is most likely not updated to work with the rom. Each rom comes with its own kernel so you really don't have to flash a new one. I would flash the rom and gaps and see what happens. Leave the kernel out of it for now. You have to remember that not all kernels work on all roms. Many roms are making it so only their kernel works properly.

Still no-go. Freshly downloaded purenexus_shamu-7.1.1-20170215-OFFICIAL and Full_Dynamic_GApps-7.1.x-20161215, checked the MD5s, and flashed both after cache/Dalvik. Still got the same 4-color bouncing dots. Let it run like that for about 40 minutes before getting back into recovery.
Ran the same flash but this time also wiped system. Same result.
Is 40 minutes enough time? Impatience maybe?
Now back to original 6.0.1, PureNexus 6.0.1-20160821 and 3.10.40-ElementalX-N6-3.20 kernel.
Any ideas?

You are doing a full wipe right? Wiping system and data before flashing?
Also encryption could be an issue. If your device in encrypted or the kernel did not remove the force encryption flag. That could take awhile as well.

Get the Feb 15 GApps too instead of the Dec 15 GApps. Don't use old GApps.
https://forum.xda-developers.com/android/software/gapps-dynamic-gapps-t3487192
Also make sure that the GApps are 7.1.x and not 7.x.x or you get a SDK mismatch. What does the recovery log show?

Got the Feb GApps, wiped Dalvik and cache... this time I let it run for a bit over an hour in case the encryption was an issue. There's a little over 19 GB in files. I figured an hour would be enough but no luck. Had to recover again from backup.
TWRP gives 5 items that can be wiped, Dalvik, System, data, Internal Storage and Cache. I was of the understanding that data pertained to user data (photos, notes, etc). Most all of that is backed up but I'm unclear on what needs wiping for this Nougat upgrade. When I wiped system, it didn't seem to help - although I was using the older GApps at that point. I've seen documentation that says to wipe these items at the outset and others that suggest after the flash is complete. Both? Which ones?
I don't want to resort to drastic measures if it's something simple that I've missed.
Needs Nougat bootloader and latest radio--flash in TWRP. This allows flashing N ROMs while will still work with all MM or even 5.1 ROMs

What TWRP version? Old one cause problems on newer ROMS. Newest is 3.1.0, but 3.0.3 or 3.0.2 should be ok.
Wipe everything - /system, /data, /cache. /dalvik. Do NOT wipe Internal Storage (camera photos, downloads, etc.) before flashing. Data is usually app data, so make a nandroid first to save it, but app data can usually be restored with Titanium Backup or Google will restore it on setup. Just do not restore any system data.
Bootup on clean flash does take time, but normally no more than 20-25 minutes.
Try reverting to stock
Install stock firmware using adb
TWRP version might be the glitch.... Mine reports 2.8.5.0 in recovery mode. I'll update to the latest and retry after wiping all but internal storage. If that fails, I'll flash the boatloader and radio.
Once more into the breach.

Hi... Save your internal storage before processing. Just in case... TWRP 2.8.5.0 is pre nougat and incompatible.

You should really update the bootloader/radio to the latest once you update the TWRP. Updating the bootloader/radio will not affect your internal storage.

Wiping system, data, cache and Dalvik seems to have gotten me to Nougat but apparently root did not come along for the ride. Wasn't expecting that. Is that par for the course?
