[Q] How to know if your device is on bootloop? - General Questions and Answers

Hi there, so i flashed a new rom using cwm, an ics rom to be in fact in my newly wiped sgs2. the boot animation is the same as galaxy nexus and has been repeating for almost 3miutes. its not like the one in stock s ii that you will really know that it is in bootloop. is it really a bootlooop or just a flashed firmware still loading up?

If it doesn't fully boot and just repeats the initial boot image or splash screen, it's a boot loop. It's in the the name...boot loop

Sorry, but I guess I should have said to try to reflashing the rom but to make sure to, in ClockworkModrecover, clear data twice - clear cache twice - go into advanced menu clear Dalvik cache twice - and if you've definitely have charged your battery to %100, go ahead and clear Battery stats twice. Then reflash your custom rom. Sometimes stuff gets left over from a previous rom and can cause boot loops or boot lockups. I didn't nt know if clearing everything twice is needed for all of them but I always do it twice for each to make sure nothings left over, I haven had a boot loop cause of that in a long time. Let me know if that helps at all.

HELP! G2X will not boot up, will not factory reset

I just got a replacement G2x and ended up one click rooting it. I installed bloat freezer and started freezing programs that I did before. I accidentally froze "launcher" since I am using launcherpro anyways. It seemed to be ok, but then I froze App Pack and it gave me the constant force close like some of the apps do. I pulled the battery and upon starting it up again, it gives me the LG logo at full brightness. It then dims to half brightness and then goes black. (unresponsive)
I try power + volume down and it brings me to the unpacking android like it should for a factory reset. Shortly after, the screen goes black and just sits there unresponsive but with the notification lights lit up. I had not gotten around to doing an nvflash recovery yet and dont have rom manager or clockwork installed yet. I just want to get back to stock or be able to at least boot up.
Please help.

I believe factory reset on stock recovery is volume up + power. Either way, I'm pretty sure you have to hold them until it starts the restore process.
Nvflash CWM recovery, restore the stock nandroid dump.
This should take roughly 10 mins to complete and will get you back to stock (minus the recovery).

what he said. took the words outta my mouth ahah
Thanks guys, I had done the NVFlash before, I was just worried about bricking my phone if I did it when I wasn't supposed to
Well after doing all that, it still only boots to the LG Logo. I can enter clockwork recovery and even do a factory reset (and the G2X stock nandroid backup) but when I restart the phone it won't bring me past the LG screen.......
Any other suggestions?

Send it back saying they sent you another messed up one, and then again I suggest to you and everyone else to forget about rooting, since there are more negatives that outweigh the benefits to a rooted phone. It's just foolish and it's no wonder that the G2x has a lot of problems, it's because most that do complain of a problem have rooted or tried rooting the phone.
If I send it back and they get it to boot, it will still have superuser which means it was rooted. I don't want them to void any warranty and I am sure they would not have let it out of the warehouse like that.....
Rooting is not the reason the G2X has problems. LG is the problem....
Anyone have anything useful for me to do. I like that I can at least enter recovery and do a factory reset, I just need to get this thing to boot past the LG logo.
Did you do full wipe before restoring. Install a different rom instead of stock....

After you did the reset and it would not boot up - have you tried pulling the battery and booting up again? I have had to do that a number of times.
I have pulled the battery so many times. What will flashing a new rom do that a stock rom won't?
After you restored the stock nandroid, did you wipe data, cache, dalvik again?
Wipe before and after restore. It works, I've done it oodles of times.
In addition to what GideonX posted, make sure you format system, format cache, and format data.
I did just as Gideon stated and it still cannot boot past the LG logo. I wiped everything before, flashed Gunmann's stock nandroid backup, then wiped everything again....
What now?

This same thing happened to me on my second night of fooling around with the phone. I fixed it by reflashing with the nvflasher. Make sure you follow all the steps to the T.
I followed every single step exactly. I ended up just putting the battery in and it booted fully after about 5 hours of sitting there. The battery was at 1% about to die. I don't know what made it boot up near its battery death. Either way, I was able to unroot and the next time I turned the phone off, it wouldn't boot again. It looks like it is an issue with the phone itself
Same problem
Hey, did you fixed the problem??
I'ts happening with my G2x...
Some times, it wont boot up, i leave it alone, and then powers up with 1% or 0% battery.
Today booted up with the right charge. And works flawlessly. But if i power it off i'm shure that the problem will be back.

Infuse stuck in boot logo loop

My infuse is rooted with zues. A few weeks ago, it was stuck on the samsung boot logo and it keeps looping. I wiped data and cache and installed zues again and it was fixed. Last night, this happened... so my phone turns on for 2 minutes max, then turns off and starts the loop. I can only keep on for 2 minutes before it starts looping again. by saying keeping it on for 2 minutes, i mean everything works! talk, text, games, ect...
so i turned it off, went to clockwork or root menu, whatever you guys call it, and i wiped data and cache. Whats weird is that even on boot menu or clockwork, it still wont stay on, it keeps turning off and turns on and loops!
i installed zues again, still turns off and loops
next step? is my phone dead?
Did you have any undervolt settings applied?
The phone is not underclocked, it is not overclocked. It was rooted, I unrooted it. its currently unrooted absolutely factory stock and still doing that. What can I do to fix this?
warranty is over as of 3 months ago
Forgot to mention the most important thing!!!
When I am on the phone with someone, it works perfectly forever, as soon as i hang up, it ends the call. this key thing might help someone find the solution!!

Don't panic just yet... I doubt your phone is dead.
You say you've "wiped data and cache". Are you also making sure to wipe /system and Dalvik Cache?
Try flashing Zeus again.
Boot to CWM, Wipe EVERYTHING (/data, /cache, /system, Dalvik Cache). (Alternatively, get "Clean Wipe" from Qkster's Scripts and flash with CWM to easily wipe everything.)
Flash Zeus and go.
If you're still having problems, perhaps try a different rom?
okay, I read everything you guys wrote.. This is where I am, I am open to suggestions
I am on the stock rom and unrooted. Phone still boot loops. What should I do now? Step by step instructions would be great. Im unrooted, so should i root again? even though im having this problem?
bump! really need help with this guys!
Have you tried going back to stock?
If it keeps looping while on download mode then I would say you are dealing with a hardware issue.
Sent from my sweet & buttery Infuse
It just came to me that it doesn't loop in download mode. It does loop in clockwork, I flashed the stock kernel using ODIN and went completely stock through ODIN.
How do i fix this? i'm pissed that i had it for a year and three months and right after the warranty ended, the phone stopped working! Samsung never again unless this issue is fixed
I'm a newbie to flashing, so take it with a grain of salt. At least two more things seem worth trying to me:
1 - Try factory data reset (assuming you already tried the wipe Davlick and wipe cache). I'm not positive what this does, but I think you may lose some of your data if it's not backed up.
2 - If that doesn't work, try qkster's Heimdall UCLB3 stock (since you can get into download mode...shouldn't be a problem). This is complete back to stock so should be able to clear any software problem I'd think. I know you may think it's redundant since you are already back to stock, but worth trying imo since some things just take more than one try, and you may have had a bad flash the first time around.
Why zeus? try latest ones with jelly bean
Hey,
Try other roms based out of jelly bean. They are pretty stable. CM10 with 09/14 build is the latest
Here are the standard steps if you have CWM enabled.
1. Factory re-set (only when switching between different roms).
2. Cache partition wipe
3. Dalvik Cache wipe
4. Install the zip file
5. Re-start and wait until it re-starts. Initially it will take some time.
I have tried various roms and versions as well. Best would be the CM10 Jelly bean.
Thanks Kran.

[Q] [Help] Stuck on HTC boot screen, other issues in thread

(Just wrote a detailed post and when I went to post, it said I wasn't logged in and erased it...will give a quick run down and can supply more detail where needed as I work through fixing my phone)
Stuck on the white htc splash screen is my most recent problem. Sometimes it gets by that but then boots into recovery. I think bananagranola has the solution in their sig to flash a boot.img. and think I'm comfortable with how to do that, just need to find that file (in the ROM zip?)
What led up to this.
Successfully unlocked and flashed to CM7 back in late Jan/early Feb.
Started experiencing random freezing about two weeks ago.
A week later (last weekend) flashed Jellybean (R10). Worked great for a couple hours then started having the same random freezes.
If things froze I'd have to remove the battery and reboot. After a day or two of this though it'd get to the point that even that would leave me on a frozen jellybean boot animation. So I'd go and factory/data reset in CWM Recovery, wipe cache, wipe Dalvik then reflash the ROM. and I'd be good for a little while more.
Tried flashing back to CM7 but Recovery didn't like the file (it has a good MD5 when checked) Had tried my restore point from early Feb before to no avail, so decided this morning to try other restore points from the last few weeks, right before and after switching to JellyBean. They got further, the first step is something with boot then something with system. It failed on the system part. OK...so I wiped and reflashed jellybean again, and now I am to my splash screen freezes.
I should have asked for help much earlier (lesson learned!) but here I am asking now...what's the first step.
Do I test out and see if I hang on the splash screen again. I haven't turned the phone on in about an hour. Worried of screwing it up more.
Thanks all.
TL;DR Believe I'm stuck on splash screen and know solution to that. Have had phone flashed with new ROM with no prob for months, recently freezing, regardless of ROM. Hoping for advice on getting things working again, starting with whether fixing the splash screen thing first is where to start
splash screen issue seems fixed
Seems I fixed the issue with the splash screen. Booted into recovery and reflashed the Jellytime ROM.
Got all the way into Android. after a few minutes I rebooted into recovery and loaded the gapps. Rebooted, it updated apps (not downloading, the popup that says it updates) and was setting up my account when it froze again as I entered a wifi password. Pulled the battery and tried again, got through that and all the way to the lock screen. froze shortly after that.
Now when I reboot, it locks on the boot animation. The Jellytime screen flashes the brightness as few times as things are loading. after the 5th or 6th flash it just sits there frozen.
a new SD card is in the mail, so I may post again when that arrives to see what I can do with an almost clean slate.

That doesn't sound like an sdcard problem. Are you full wiping?

I'm wiping data/factory reset and cache as well as the dalvik cache.
The steps to flashing a ROM by sashank at link mention to format /boot and /system. I didn't specifically do those...but don't see the option for /boot in any menus I've checked.
A week or so ago I was beginning to suspect there was an issue with the memory but I never found the right search terms to find out how to do a memtest if that's what would have found any problems. Yesterday I did come across some discussion of a corrupt partition/bad chips in some HTC devices. I followed the directions there and through adb ran dmesg | grep mmc0 and the output was similar to the 'normal' one given and showed none of the messages they claimed to indicate a bad chip.
I'm not too concerned with any data from the phone...I backed all that up long ago and the rest restores from my google account. So if I getting things running would normally raise concerns of lost data, that's not an issue for me.
Thanks for taking the time to read. I try to be brief...but don't want to leave anything out.
Wanted to update here before trying to start a new thread and clogging up the board. The title of this thread is not up to date though.
I can hboot just fine and boot into recovery just fine. My phone is unlocked and rooted, ENG S-OFF from when I used AAHK quite a while ago.
When trying to navigate from menu to menu in Recovery I will get the following error messages (best I remember from last time I was in there, I've let the phone be for the last 2-3 days now)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
This doesn't show up at first though, only after I do a Wipe Data/Factory Reset. And if I understand correctly, that wipes /cache so maybe that's causing these errors?
Anyway, after wiping the dalvik cache I can flash a ROM, I've been using Jellytime, I haven't been able to rollback to CM7, not sure why not.
Jellytime will run though...at first! the first couple of boots I can get in and get through registering my google account and have it begin restoring apps if i make that selection. The time I have to work on the phone before it freezes gets shorter and shorter though. I have to remove the battery to get it to reboot. Eventually I am left with the phone hung during the boot animation. I've left it for over an hour before...it's definitely hung there.
So my reading leads me to believe corrupt partitions. I'm not finding a lot on what I should do to reformat and maybe repartition or whatever I may need to do to recover a functioning phone. I don't care about any data on the phone. I just want to get things working again. I ended up getting a new SD card during all this that arrived earlier. If I can get my phone working, I'd prefer to use that from here on out too. I can use the adb in recovery mode just fine if that's necessary to rejigger things to work.
Can anyone help reset my partitions, if that's what this issue seems to be? If not...any ideas?
Thanks.

Yes. Everytime I've flashed, I've followed:

wipe cache
wipe dalvik cache
unless there's more I can do.

OK, I'll give this a try. The issue with the freezing is why I moved from CM7 though (which had been stable for four months) so it's reproduced itself in different ROMS. I'll post back once I give this a try. Thanks.

I gave Android Revolution a shot. During the flash it gave a message which might also be why I wasn't able to flash back to CM7. The MD5 did verify.
Code:
assert failed:write_raw_image("/tmp/boot.img","boot")
When I went to reboot, I ended up in Jellytime. Of course I had to sign back in to google apps and those things were reset from the dalvik wipe. Shortly there after the phone froze.
On reboot I tried a logcat. Didn't get it right from the start (you can send the command during the boot animation if I read correctly) but captured the failure of things. It's back around the 09:02 portion of the log. To my eyes it looks similar to others I've collected. Especially the message
Code:
Fatal signal 7 (SIGBUS)
though I haven't been able to figure out much about that, or identify what it is before that that could give another clue as to what is screwy since that's maybe (Probably?) related to the flashing issues.

[Q] Stuck on Team Kang logo? Phone won't boot..

Hey! About two weeks ago I rooted my Samsung Galaxy S 4G and installed "Valhalla Final" Gingerbread 2.3.6. Everything has been great until today :crying:... I was talking on the phone and the battery went dead, I got home and charged it then tried to turn it back on. When I did it started to boot up and then got stuck on the "Team Kang" unicorn animation. I'm a noob and not sure what to do? I have tried removing the battery, etc. and still same result. HELP!! What should I do?? Thanks in advance...
Try doing a factory reset in recovery.
To get to recovery:
pull out your phone's battery
put the battery back in
hold BOTH volume keys and do NOT let go of them
Press the power button long enough for the phone to turn on
Once you are in recovery you can let go of the volume keys
What I ended up doing was going to recovery mode, wiping the cache and then flashed the same rom again.. Question is what would have made it do this to begin with? Is there a problem with this rom that im not aware of? After I did the above it now works fine other than having to go through and redo apps, etc..

There is no problem with the rom, if you wipe cache before upgrading. I usually wipe dalvik as well. Wipe factory if you are coming from a different rom.
I do the previous three for each rom I use, on any phone I own. I don't always trust that the developer wrote in the updater-script to attempt to wipe cache & dalvik when flashing.

[CM] SM-N900 Stuck at optimizing apps, bootloops

Hi there!
After about a week ago, I’ve turned off my Note 3. Then two days later, when I wanted to use it, I’ve turned it on. After CM logo appears, its says:
“Android is starting
Optimizing x apps of x”
I know this is because of ART, but after it finishes, my phone reboots, and CM logo appears again, and nothing happens. After a while, it starts optimizing apps again. Now I left it for 2 hours, my phone didnt boot up.
What should I do? I didnt flash any new kernel, rom, recovery or anything else. Im on CyanogenMod, with CWM recovery. I dont want to factory reset, because of my photos and videos.
Even I tried to start in safe mode, but I couldnt get to it, and Im not really sure that I tried to enter safe mode properly.
Please help!
Just dirty flash the rom again through cwm.
See if it works
It's high time you flashed TWRP already.

Ahh I would suggest you to get TWRP, The world has moved on and I think you should too! It's just a little better at things overall. TWRP can be flashed through ODIN. As for the Bootloop, try dirty flashing the ROM. Just wipe the dalvik/ART and cache and leave the rest as it is.

What do you mean on “dirty flashing”? Do I lose my data if I flash my rom again?

No you don't, dirty flashing = installing the same ROM without wiping or resetting any data sets, just reflashing that zip again, JIC some files got corrupted, if that doesn't help you might have to give it a fresh start.
