CM9 boot animation loop

I have clockworkmod recovery installed and rooted. It's been a few months since I rooted, and can't remember exactly what I did, but OTA updates stopped working. Hence, I am still on gingerbread.
Trying to flash a custom rom now, CM9. I tried the rom manager method several times, found out that wasn't recommended, and then tried the recovery method.
The same thing happens either way: it boots into CM9, but the boot animation keeps playing.
With the rom manager method, I tried wiping nothing, then tried wiping dalvik only, then tried... whatever the other option was, wipe cache and data?
With CMW recovery I downloaded CM9 zip and the appropriate GAPPS, moved onto the internal SD card, booted into recovery mode Wipe data/factory reset, then Wipe cache partition, then install both.
I'm able to restore from backup each time, but this is annoying.
Thank you

1. Install ICS Radio (UCLF6)
2. Wipe Data/Factory Reset
3. Format /System
4. Install CM9.zip
5. Install Gapps.zip
6. Wipe Cache/Dalvik
7. Reboot
:good:

So "UCLF6" appears to be rom that is similar to stock, I'm guessing the idea here is that I'm resetting the phone but retaining root, the idea being that something on my phone is messed up and preventing CM9 from booting but doesn't prevent the current rom from booting?
Two other questions
1. Won't format/system wipe out all my backups in addition to my data?
2. Have you had or seen this problem before? I'm hesitant to commit myself to something, especially with no backups, if it's just a theoretical fix. I do appreciate it either way.

UCLF6 is an ICS modem/radio you need if you're coming from gb.
If you back up though CWM you can restore again later if you want.
Formatting /system will delete the operating system.
Formatting /data will delete your apps/settings/wallpaper etc...

I had a similar boot animation loop when I went from stock GB to stock ICS. What seemed to fix it was updating my CWM from 5.0.2.6 (non-touch) to 5.5.0.4 (touch). (BTW, I couldn't find an advantage of stock ICS over stock GB. I have since put on CM9 which I'm liking).

Still got the boot loop.
When I did the "Wipe data/factory reset" I did get an error message during one of the processes"
"Error mounting sdcard/.android_secure!
Skipping format"

I had a boot loop problem when I first tried to flash JB. I went from GB to ICS with a custom rom a few months back, but I couldn't get any of the new JB roms to work. I ended up having to upgrade my CWM to the touch version in order to get JB flash to work. Also, a tip-- the boot animation will take a minute or two even when it is working. Don't assume it is still a problem if you see it more than once.

[Q] Problem With Flashing SCH-I535

The very first ROM I tried to flash was a version of CarbonRom. I was unsuccessful, as i got the installation aborted message. I then tried a couple of other lesser know ones, with the same luck. Lastly I tried CM 10.1, and with that, i had success. It was the only one that would work so far. Yesterday, I downloaded DU 4.2.2, and A new nightly version of Carbon (Specifically for my phone) With no luck of installation. Am i doing something wrong with these? Is there a different method of flashing i'm missing?

what is the procedure you take to install?
I usually go this route:
1) Boot into whatever recovery you have
2) Wipe Cache/Davlik
3) Install custom ROM
4) run a factory reset
5) Reboot

I have Philz custom recovery which based on cwm version 6.0.3.7 which when you tap wipe data you will then have the option to clean install for new ROM.

Sorry for not replying earlier, i never got a notification. I'm using the most recent version of CWM. My usual order is :
1. Boot into recovery
2. Factory Reset
3. Clear Cache Partition
4. Wipe Dalvik
5. Format /system
6. Mount /system
7. Flash new ROM

well we now have 3 custom recoveries to choose from I like the newer one since I can install a new ROM in fewer steps.

i would do a factory reset after you flash your rom too, can't hurt.
of course on updating the same ROM, I only Wipe Cache/Davlik and that's it.

Bad download? Does the md5 match?

after making sure you wiped everything make sure the download itself was proper I am running it flawless right now

Thank you for your reply.
Does TWRP Recovery on Galaxy Note Edge SM-N915T as same as N915S, can I can use it ?
Since I cannot find the N915S version in XDA, thanks.

Try this... Go to recovery... Wipe cache.. Then wipe Davlk cache... The wipe both cache and Davlk cache together.. Then go and try mounting cache again..
edit: Sorry I am way too tired.. I just noticed your problem is system... Yes use TWRP recovery.. I found its best to flash it first as recovery on a fresh root. See is you can mount system in it.. Most have a problem with mounting cache at this stage... If system works and cache becomes the problem use my suggestion... Once all happy them flash CWM as your recovery. Hope this helps.
Edit 2.0... http://forum.xda-developers.com/showthread.php?t=2945942 This thread goes thru everything you need... if there is no TWRP for your devise there should be working alternative.

Yes, I have follow http://forum.xda-developers.com/show....php?t=2945942 and re flash the auto CF and CWM, but the issues still not fix, root checker show the phone rooted, but still cannot mount the system and flash any custom rom
Thanks.

Failed to mount /data (Invalid Argument) in Micromax Canvas Juice 2. Aq5001.

I have a custom rom downloaded. But to flash it, I need to erase everything. That I am unable to do because the recovery dosent wipe data. It led to a bootloop. I got back the stock firmware and tried again and same result. Further more, I cant even factory reset. I'm using TWRP 3.0. Someone please help!

Ive tried that 4 times till now. It has been in a bootloop thrice. And I flashed stock. I currently am using stock firmware but want to flash the custom rom. The recovery is failing to wipe data because it is failing to mount data.

Try this
1. Reboot to recovery (TWRP)
2. Select wipe.
3. Select advanced wipe.
4. Check system.
5. Repair or change file system.
6. Select change file system.
7. Select format type.
8. Swipe to change.
9. Select repair.

there is one problem with stock rom. its encrypts the data partition right after installing stock rom, therefore twrp can't access data partition. i had similar problem earlier. this is how i managed to fix.
solution: http://forum.xda-developers.com/showpost.php?p=67980158&postcount=7
i suggest you to stick with stock rom, because right now whatever roms or recoveries are made for this phone are blindly ported (just copy paste roms). i have tried about 3-4 roms for this phone, all had major bugs especially battery related. there is only one developer who made a stable rom so far is beingtejas, search his thread. if you really want to use a custom rom, try THIS rom made by gaurav kesarwani with help of beingtejas that is why i am suggesting it you otherwise it didn't worked for me atleast.

Bootloop after flashing TWRP and wiping data,cache and dalvik

I just want to start by saying that I know how to recover my phone from this but I do not understand why this is happening. I just want to flash back the official rom and then install twrp and do a "factory reset" but after wiping with TWRP my phone gets stuck in bootloop. Am I doing something wrong?

In TWRP you did 'factory reset' there isn't that option so which partitions did you formated? If you formated system, then is no more OS on your phone so what you trying to turn? xD If you want flash stock then use newest Odin 3.12.7 and learn some guide how to flash stock depend from which version (f.e. 7.x) you're coming. The guides are on that forum.

It says in the title which partitions I formated (date, cache, dalvik). I know how to flash stock. I will explain again the exact steps I did:
1. Flashed official rom using Odin after having a custom one.
2. I started the phone to check that the rom works.
3. I flashed TWRP 3.1.1 using odin.
4.Wanted to "factory reset" using TWRP, so I wiped cache, dalvik and data partitions.
5.The phone starts in bootloop.
It looks like TWRP doesn't wipe the partitions as is should.

Is not possible to TWRP didn't wiped right partitions. Why you wanted to factory reset if you flashed stock and you got factory settings? Flash stock with Odin again...

You need flash latest SuperSU zip in TWRP to fix the bootloop issue

Maybe that. Personally I never flashed stock in S6 xD

You have to flash the SU Binary after flashing TWRP, else you will face a bootloop

Magisk. No "SuperSU". Then always will be it resolve if be only "Flashed TWRP". (Odin versions doesn't be affect of a bootlops with a 5secs~)

i flashed twrp now stuck in bootloop, not sure how to flash super su now?
