Nero v3 infinite reboot issue

Hi guys
So I installed Nero v3 on my Vibrant, and all is well. I followed the steps on the Nero thread. I like it very much.
Then I decided to flash my gf's phone. It seemed to go well at first, but then some odd stuff started happening. First, I can't open the "Settings" menu - nothing happens. Second, lots of stuff force-closes all the time.
Those two are minor issues, though. Somewhere between 5-15 minutes after flashing, the entire GUI will force close. The phone will vibrate, then the Team Whisky logo will appear again (as if rebooting), and the GUI will appear and begin the regular startup procedure. It will get as far as "Preparing internal SD card" before the GUI will crash again. This cycle continues indefinitely. Once it has begun, not even pulling the battery and rebooting it will solve the problem.
Any advice?
My plan is to find a way to back up the SD card data and format it, since it always crashes on "Preparing internal SD card." However, I doubt this will help, since the other issues (constant force-closes) don't seem to have anything to do with that.

Was her phone stock before you started tinkering with it?
In any case I'd suggest re-download nerov3 (to avoid corrupted download issue), ODIN back to JFD (remove the ghosts from the past ROM's) and reflash.

Phone was stock aside from rooting for the purpose of TitaniumBackup. It has never had anything installed on it.
I'm currently Odin flashing back to stock, and I'll give it another shot.

Good luck!

Well, I did the Odin flash to stock, then installed Nero. After first boot, I left it untouched for 20 minutes or so, and then did a clean reboot. Upon starting up, I was once again stuck in the loop.

Did you re-download nero? It might be a corrupted download, I haven't seen anyone with the same symptoms.
Does it happen if Voodoo is disabled?
EDIT: Saw that you didn't even have a chance to enable it, hmm, try a different ROM? Axura or Eugene's work.

No, I didn't try re-downloading it. Perhaps I'll give that a try, although it is the same file I flashed onto my phone.
After a bit of time playing with Nero, though, I'm considering going back. The parts that work are slick and wonderful, but it very much feels like beta software. In particular, scrolling lists or web pages is choppy. I've heard this criticism of Android before, but I've never experienced it with the original Vibrant software. It was always so smooth. It makes me think that maybe Samsung was using GPU acceleration in some places. Also, I seem to have some problems with the touchscreen becoming unresponsive, especially in the browser if it's blocked waiting for data (another bug...).
Is it possible to run the JL5 modem on the stock image? That would be great.

[Q] eLocity just quit...won't boot up

I have been running my a7 with dexter's mod 1.4 for about 1 1/2 weeks...everything has gone well. This afternoon I turned on the device and it failed to complete boot. The word Android would come up and then nothing. I tried to reboot, reset, but device would do neither...nor would it turn off completely. I kept trying to take it into recovery mode and then after several tries was able to wipe, do update again, and get everything back as before. What would cause this and should I look for this to happen again? deepmagic
My a7 was running well for about a week since it quit...but today when I booted up device, it failed to recognize sd card...same card used for updating to mod 1.4...same card I've been using to listen to my music, etc...but now won't recognize...I've tried two different micro sdhc cards..formatted, reformatted, but device continues to display mount sd card...all else works fine! Does anyone have any new ideas? I can't even reinstall mod since a7 can't read my cards. Thanks for any input that would be helpful. I understand these issues are ongoing for many out there...what to do?

Mine has hung on a black screen on me. Seemed that it didn't fully come out of sleep mode.
I was able to recover by holding the power button for 15 seconds to hard power down. No data loss.

Exact same thing happened to me this morning. Tried to reset - not happening. Hard powered down. Don't have time to try anything else right now. I'm new to the forums and new to android. Wish me luck! I've been loving my A7, and much appreciation to Dexter and all the other knowledgeable hackers/modders/posters.

hey the same thing happened 2 me twice. Once the first day after i got it, since i had only had it for 1 day i wiped it reinstalled dexter's mod 1.41 and it worked. First app i installed was backup root. Now, a week later the exact same thing is happening. This time i dont want to wipe it because of all of the apps i have installed, games ive played etc. Any ideas? Could we just try reinstalling dexter's md without wiping? Or wiping reinstalling and recover from a backup?
Also have you installed busybox? I had just installed it both times before it failed to turn on. Maybe its just coincidence but you never know..
-D
Thanks to anyone who can help! and also thanks Dexter for all your hard work as well as everyone else that has contributed to the elocity, im lovin it! (when it works )

success!!!!
I got it to work! I don't have a permanent fix but if it happens again just boot into recovery and reinstall the dexter's mod update 1.41 and it works again! No wiping required. This isn't a permanent fix but it will work until we find one
-Dylan

Hasn't happened to me (yet) but I didn't upgrade to the newest ROM. I'm still using 1.3and it has been very stable. Only issue I've had was when I tried to use Killswitch to go to sleep mode when the cover is shut (great idea) but it didn't work and froze all except the live wallpaper. Weird.
Good luck, guys.

in the event it does happen to you, you might want to check out my apx thread for reflashing the factory firmware if you can't get your tablet unstuck. theres alternatives if you don't want to get stuck again.

The method you outline seems so complex...way above my abilities, but makes me wish I had followed though on some early programming training opportunities. That was the road not travelled.

okantomi; while i wouldn't encourage others to follow thru with procedures they fear would cause more harm, i would mention that if you google up my nick you'll find i've been able to do much w/ android software and devices while not knowing anything about programming. if i can do it, anyone can. i just wanted some themes for my phone.
i'm just an android hobbyist by night (and when i get a chance during the day), and a computer tech by day. no programming expertise, but i can reasonably reverse engineer and port software and components using simple file managers like ztreewin(trialware).
don't be mistaken that the folks out there providing you solutions necessarily know anything about programming or software development. just how to chef up files at different levels. i understand this doesn't go for everybody.

Thanks for the encouragement. I'm impressed with what you've been able to do. It is also nice to read upbeat comments about the A7. There is something sort of special about a device that you really almost have to build yourself... putting so much into it... biting your fingernails to nubs with each ROM flashing. You don't get as attached to any device that is 100 percent complete right out of the box, though of course there would be a lot less aggravation.

[Help]Note 4 Battery draining fast :(

Hello.. I'm sorry for my bad English grammar, if you don't understand, please ask me.
I don't think I understand my phone well so I'll just tell you what happened then.
My note 4 is 1 year old. I think it is Thailand's model as I checked the model number when I'm rooting it.The battery life is long lasting when the first time I got it, I'm not sure when the battery life start to get worse. I'm pretty sure it is happening after Lolipop update, not sure if happens before that. I do not install much games, I do have like 5 or below games from playstore, small sized one. I do installed Clean Master to clear junks when I started feel lagging.
Until recently, because I needed root access to backup my game app data so I went root my note 4 using the odin method. I'm still in my stock firmware. I did faced a problem when Security & Policy update pop out , I did update and it went bootloop(I think it's called that) until I can't access into my phone, I did pull out battery then insert back few times and seems like it rolled back. These few days I was researching how to extend my battery life, I read lots of post said some apps is draining apps as it still not yet adapt to lolipop update? also saying Clock apps draining apps, not even wakelock detector able to detect it. I tried SetCPU and set my CPU below 800 Mhz and even 400min 500max(Just a question, why I didn't see On Demand ? Only Interactive, Performance & userspace) , I did not see any obvious results after doing all these things. Oh , I even went uninstall some bloatwares, I did download Greenify and hibernate some apps.
Now, I'm trying this method to see if it solves the problem. http://forum.xda-developers.com/andr...-life-t3095884
When I was about to Nandroid Backup my datas, to confirm it is it
1. Boot into recovery mode
2. Backup?
But then I couldn't boot into Recovery Mode( Volume Up + Home + Power ) just now, It stucks at boot screen, before the animated samsung appears, just Note 4 with model names something. There's no blue text above, and it just stucked there. The only way to exit from there is pull out battery and insert back again. I'm planning to download QuickBoot and try if can access to Recovery Mode.
Seriously, I don't know much about mobile technology, I just wanted a smooth phone with great battery life. I suggest to stay with the stock firmware, I'm still considering flash it to CM12.1 , people said it help with the performance and battery life, I do not like the interface of it, unless it solves all problems if not I'll not choose to flash into that. (Oh, can I use Odin3 to flash this? Can I use Odin3 to flash every rom? I don't really understand about rooting, is there any newbie guide for these kind of things?)
My questions are:
Can you suggest me few ways to solve this problem?
Is the method does help to my phone?
Why I can't boot into Recovery Mode?
What happened actually?
Edit: Or even factory reset or wipe partition(if I'm able to boot into recovery mode) helps? i did not try it yet.
Thank you for reading this even you can't help me.

[N910F]Random reboots (links to logs included)

Hi,
My N910F has recently been acting weirdly. It either randomly reboots itself, or just freezes for several seconds when switching screens or scrolling/tapping buttons. This started a couple of weeks ago on stock 5.0.1 (this version, I think) running Emotion kernel. This was running fine for a while; I didn't flash any new mods during this time, although I did switch between AEL kernel and Emotion once or twice without much success.
Thinking it was just one of those situations that called for a clean slate; I backed up my important stuff, booted into TWRP to wipe all partitions, then flashed stock 5.1.1 via Odin (this version, which I'm currently running). But even before I rooted it once again the phone was displaying the same aforementioned symptoms, both during and after going through the built-in setup wizard. This behaviour continued after flashing TWRP and AEL kernel v8.2, which I'm currently on at the moment. If it makes any difference I've also noticed that the lower my battery level, the more often it reboots itself. The battery level also "yo-yos" sometimes, usually at lower levels.
I've uploaded the relevant logs as advised elsewhere for anyone who can decipher them, as I otherwise don't know what to look for. This includes my last three kmsg dumpstate logs (just in case it's a slightly different cause each time), as well as my logcat and dmesg files (whatever they are lol) which I got using the SysLog app.
Any help would be appreciated, and if you need any more info please let me know.
Thanks .

*bump*

I have the same problem. Help would be highly appreciated. : )

[UPDATE]: Once or twice when it's crashed as above, it would try and boot again but then reboot into download mode with the following text at the top of the screen above all the other info:
Code:
Could not do normal boot.
ddi: mmc_read failed
If I then pull the battery and turn it on again, it boots up as normal (at least until the next crash). Is this something that can be fixed with a fresh flash in Odin (or some other method), or is my phone on the way to its death?

Got the same issue + loses Wifi password after random reboot. Sent the phone back to the operator I bought it from 1 week ago and they did a repair. They replaced the USB-flex, did a firmware upgrade(?? ..was already updated to latest) and sent it back. I got it this morning and at first the phone now works fine and no more "mmc_read fail". But after some time the random reboots started again. Not so often now but still 4 times over the day and twice the wifi-password is lost and I had to retype it. Now I'm on the fence and just waiting for the first mmc_read fail" to happen before I complain and send it back for a second repair. I can not imagine this beeing beeing other than a hardware fail coming from a weak spot on the phone. I got the impression many people has the same issue and it really comes to life after upgrading to 5.1.1.
I also think the problem at the service shop ist that they just do a quick system test on a clean wiped phone and can't find the issue and think the phone is fine. After reinstalling my 200 apps and setting up my phone all over again, the workload causes the issue to reappear and I now have to ask the service shop for a deeper check. They accepted this as a warranty fix all though my phone has a knox trip (0-1)x4...

I've also faced random reboots on Lollipop. How i solved that? Simple. I downgraded to Kitkat. Lollipop still having lots of battery drains and bugs even on 5.1.1

[UPDATE]
I've decided to go through my network provider to get a replacement sent out to me, which they were happy to do after going through their line of questioning over the phone ("have you tried turning it off and on again", "did you try taking out your memory card and see if that helped", "did you try doing a factory reset", etc). They say it will get here tomorrow so fingers crossed for the replacement.

The ddi mmc_read fail has not reappeared yet..
It's strange.. Lately the random reboots are not wiping my wifi passwords anymore, but now after every random reboot the multiwindow is enabled and I've got to untick it in quick settings..
Latest: It seems that the random reboot may come from heavy account sync workload. I did have 5 Google accounts syncing on my phone + 6 excange accounts and when i disabled syncing alltogether the phone ran a lot smoother and the reboots stoped. So i deleted all Google accounts except my main account and for now thing seems to be fairly stable. I've also uninstalled all for me unimportant 3'rd party apps, reducing 3'rd party app count from aprx 200 to 150..
If things develop further I'll come back with more

Thanks fot starting this thread Jointfcfan...i am using 910P and have same issue of your post 1 and 4!!!!
Loosing hope on Samsung, it is really frustrating...
Tried cleaning cash, dalvic, reboots, on latest 5.1.1 k version...frozen all not neede games and apps ...only 1 google and 1 exchange account no auto sync
At next stage while rebooting it sometime going an error stating kernel panic and i have to pull battery to restart

Replacing USB-flex board at service shop has cured the "ddi. mmc_read fail" boot issue for good.
So to me it seems that when many people experiences this, the USB-flex board may have a built in design flaw making it a weak spot on the Note 4.
Also I found that the phone works A LOT smoother if using Nova launcher instead of TW. Random reboot count is way down and phone works almost normally. Still some lag, mostly when unlocking screen, but reboots happens only 2-3 times a day now. Still random rebooting enables "multi window" option every time..
I've also rooted the phone now using CF-autoroot. I've flashed Philz CWM recovery and using it to install Wanam Xposed. So now I can run Greenify properly in Xposed mode and automaticly hibernate apps including system apps..
NB! Be aware, flashing root and custom recovery trips Knox counter 0x1 permanently and MAY void warranty
I have also mailed my operator asking them to take in the phone a second time for check/repair, alt. replacing the phone. I guess when they did system check 1st. time without issues after replacing the USB-flex, it was done when phone was reset to factory and under no significant workload.

N910F stock crash and bootloop after 6.0.1 update

Hello people of the world,
after reading a lot of posts here I still can't fix my phone's issues, so I need to post. Bear with me...
I have an N910F which was entirely stock and functioning without problems. Two days ago I accepted the official update. After that, the phone regularly lost connection to the mobile net, froze, and restarted. It would work for a short while until it froze and restarted again and again. When I tried to use the camera, the live picture was completely distorted. The phone crashed and has then gone into a bootloop.
I pulled the battery, did a recovery start and wiped the cache. No difference. Factory recovery next, no difference.
I have since tried several stock and custom firmwares, always taking care to follow instructions and use the correct bootloaders, modems, etc. TWRP is working.
When I flash a stock firmware, it will go into a bootloop. With any custom ROM, it will crash during startup (logo) and switch off.
Any help would be greatly appreciated!

Protect the eMMC?
So, after more reading I began to suspect that the eMMC had moved on to the valhalla of electronics. Sent my phone to service where my suspicion was confirmed. Luckily, they were able to replace the chip without having to put in a new board.
Is there any way to prevent this kind of failure again, or at least make it less likely?

Yes this is a known issue after latest update you could you install only one application called wakelock so that your phone doesn't reboot and CPU keeps awake

Thanks! I had read about that.
Got my phone back from service today, they had flashed stock 5.0.1. After checking that it worked I flashed RR 5.8.4 and installed Wake Lock Powermanager. I searched for a comprehensive tutorial on what the settings do and which to use. Right now I set it to PARTIAL_WAKE_LOCK (4) but I'd like to read more about it. Any tips on that?

installing power wakelock and setting up on partial wake lock is enough.if you get trouble in starting your phone remove its battery and put your phone in refrigerator for five min.and try to start your phone.this problem also related and happens after the latest update
