Hello,
I have a AT&T Tilt 2 that is caught in the boot cycle. Splash screen comes on, it reboots. I'm quite confident that flashing a new ROM will fix it it but the phone has not had hard SPL installed so I can only flash the original AT&T ROM, which as far as I can tell is not available?
I've tried to install SPL but it won't take in the state that phone is in. Is there a way to flash SPL from the memory card? Any other suggestion on how to flash it? Is the original AT&T ROM available?
Any other suggestions on how to proceed?
Your input is greatly appreciated.
try this
copy recovery img from wiki to root of micro sd card. img should be named xxx.img, insert microsd card into phone
with phone off hold down the vol down key and the red/phone call end button then power on, with any luck you should see the tricolour boot screen and the img should be detected and flashed automatically. ensure at least 50% battery
try taking your sd card out of your phone and then reboot. if that takes it out of the boot cycle, then you have installed a program to your sd card that is putting it into the endless boot cycle. after your phone boots up, uninstall whatever program that you installed to your sd card. hopefully that helps.
if all else fails, try a hard reset. just hold down the send button, end call button and power button simultaneously. it will ask you to press the volume up button to proceed. that will wipe your phone to factory settings and then you can hardspl your phone and flash away!
Milo, thanks for your reply... I can't seem to locate that recovery img on Wiki, hate to ask but can you post the link?
spacemonkey, I've tried those steps and it's still caught in the boot cycle.
You might want to explain how your phone got caught in the boot cycle to begin with. If it happened randomly, and you weren't trying to mod the phone, then just take it in for service. But somehow I doubt that's what happened. What were you doing? How come you don't have hard spl on there? What did you try to flash onto your phone, and how did you try to do it? These are all important questions that you should answer first before blindly flashing things to your phone.
The unit froze up. Tried to reboot the phone, it boot looped. Tried a hard reset, it continued to reboot.
It initially happened when a text message was coming in.
May just have to send it in. It doesn't want to take a flash of any kind it seems.

If it just crapped out on its own, then the last thing you want to do is try to fix it on your own (other than doing the obvious like hard resetting and pulling the battery). Just return it and get another.
Well it's not that easy since I'm in Canada and it has to go to AT&T so I thought if I could get it going it would save me a lot of hassle but it seems I have no choice!
My nexus is stuck on the google boot loop since this morning, i am on stock firmware no root or no nothing, can someone suggest me how can i fix this issue. i have mac and does not have access to any windows machine so i will be greatful if the suggestions will be accordingly for mac
switch off your phone . if you cant switch off the phone then take the battery out and put it back in. Press the volume up and down key along with the power key . this will take you into the bootloader. press the volume down button and navigate to the recovery section. press the power button . this will take you to the default recovery on your phone.
At that time you will see an android robot with an exclamation mark. press the volume up and down key along with the power once again. you should now see the option to update your phone , wipe/reset options. wipe the phone and reboot it . you should be ok after that.
I had the same problem with my gsm gnexus.
Hopefully factory reset using recovery works as krunal1981 suggested. If it doesn't then you will have to use Odin or Heimdall for Mac and preform a full restore. If you have a warranty and the first doesn't work, take it back to Verizon and tell them that your phone isn't booting anymore and they'll replace it.

Thanks Much this solved all my problems with the phone as of now, wonder what caused the phone to go in that ever ending loop
Question: Did wiping from stock recovery also erase your internal storage (/sdcard) or not?
Anyway - I have had this problem too, and all I can say is: A full wipe fixes it but only temporarily. It will happen again most likely. I believe it is a hardware problem with the internal memory. Next time it happens you should seek a warranty replacement.
when i do this all i get is the droid robot with an exclamation mark. my phone seems to go crazy at moments just keeps power cycling and gets soooooo hot and verizon just keeps trying to give my refurbed ones doing the same thing
galaxy nexus stock
Yes.. resetting the phone from the stock recovery erases everything
---------- Post added at 08:37 AM ---------- Previous post was at 08:36 AM ----------
when you get the android with an exclamation mark , press all the hardware buttons on your phone i.e volume up , volume down and the power button. this will take you to the stock recovery .
Phone just did this last night, it was on my desk and I saw it reboot to the google logo after which it would continually random reboot.
Did a factory wipe/reset, fixed temporarily, but within minutes, begins to do it again. No sim card in, etc.
Curious if there's been any more progress on this.

It's a hardware defect. The only permanent fix is a warranty replacement.
Fortunately the units with this defect seem to manifest it within the first few months so that the owner can figure it out and get a swap.
So, a bit more information here. I'll get to the result at the end.
I did the factory reset from recovery, that would allow the phone to boot and stay on for a few minutes, I found, after which it would go into boot loops again.
Once the phone was on, I had USB debugging on, and was looking at the phone files when I noticed that folders that were originally on the phone from before the wipe @ recovery would begin to appear, one by one. Complete with all the original files that I had before the factory reset. Once I noticed this, I performed a full wipe from the phone OS (Settings -> Backup & Reset -> Factory Data Reset).
This actually wiped everything, 100%. Made sure not to restore all apps from my google account, either, and guess what, more than 24 hours of not a single reboot. Heavy use for those 24 hours, as well. Been stressing the phone HARD.
Near as I can tell, there was some file or app that for whatever reason probably went rogue and was causing the phone to encounter something which I can only relate as being similar to a core dump/BSOD if you were on linux/windows. I don't study phone OS culture enough (I'm an auto service technician by trade) and haven't compiled a Linux box in over 10 years, so I'm a bit rusty on it, but it honestly doesn't surprise me that this is a definite possibility given all the different hardware configurations and all the different apps that are out there that are expected to work on everything.
So, there you have it, my experience, my fix, and what worked for me (so far). I'll keep everyone posted if I notice any random reboots or any future reboot loops.
I believe it's a hardware level defect with the eMMC. It keeps working fine again until it attempts to write some important file to that exact sector of the internal memory. Then it corrupts again and back to the boot loop.
When I had a defective unit, the longest it'd last before looping again was 20 days. Sometimes as few as five hours. If it spontaneously starts looping again - it's a hardware problem and there's no fix. You need a replacement.

So, here's an update on the situation with my phone.
The update, is that there is no situation. The phone is operating perfectly fine. Had it's OTA update to Jelly Bean a couple/few weeks back now, and is still running smoothly. Moderate to heavy data/wifi usage (past 10 days has seen 700mb wifi traffic, 1.2gb 3G/HSPA traffic) and phone hasn't been rebooted in over 300 hours.
I'll give periodic updates every month or so.
I have a stock GN, not rooted yet. Today my phone automatically shut off and now it starts back up, google logo shows up and all those colors come on for couple of seconds and then the phone reboots itself.
I can press both volume up+volume down + power button and get into a menu which gives me the options of Start, Restart bootloader, recovery mode, and power off. I choose recovery mode but then it goes on to an android sign with exclamation mark. After that I can't seem to get anywhere. I have tried volume up +power, volume down+power, and volume up+down+power but nothing seems to work. It just keeps on rebooting it self.
Any solutions to this problem??
There are two possibilities:
1) Software problem. Since you were stock, this is unlikely.
2) Hardware problem. This is more likely, in my opinion.
If you want to eliminate 1) as a possibility, you can try this:
1. Download the GNex Toolkit here
2. Install it & get the drivers working on your computer (if you haven't already)
3. Unlock the bootloader by selecting Option 3 (it'll wipe your phone)
4. Flash factory stock rom by selecting option 8
5. Try it. If it works, congratulations. (if you want to re-lock your bootloader, use option 11)
If this doesn't work, relock your bootloader and send it in for warrantee. (most likely a hardware problem)

So, I did the above method and after flashing the factory stock rom it won't start up anymore. It doesn't respond to anything at all. It seems I've bricked it
Is there any way to unrbick it now? I'm assuming I can't send it in for warranty either now if it's semi bricked. Unless it's been completely bricked which means there is still a chance of getting a replacement phone.
I have the same prob on rooted SGN
This morning I switched off the airplane mode to be available, system crashed and restarted. And then still the same again - booting / android logo / restart again.. /./. I am using Android Revolution HD 2.1.5, for last month with no problems.
I tried to boot into recovery, then wipe the cache and reflash rom and radio from sd, it is still the same. I can see all the files on my int. sd with no probs.
Please help.
I'm thinking it might be a hardware issue, but I'll wait for another member's opinion before confirming.
Solved!!!
That's what I thought - HW prob, but it seems that luck is on my side, I hope. It helped to get back on stock but with total deletion including int partition
Anyway thanks for support.

Was your phone rooted or bootloader unlocked before the problem occurred?
Anyways I've sent in my phone for warranty, hopefully samsung will fix it.
So my phone company called me today and apparently Samsung told them that it's corrosion(?) problem. When I asked exactly what does that mean they said it's moisture damage or physical damage that probably caused it. But I'm confused how could my phone possibly get moisture damage inside an otter box. I know how delegate these devices are and I know how to take care of them.
Anyhow it'll be $90 to fix it. I had no other option so I asked them to go ahead with the repairs. So frustrated with Samsung to be honest. I never dropped my phone once, never had any water damage, phone was always inside the defender case. And I still have to pay them for fixing my phone even though it's not my fault.
That's quite worrying, I just started having boot loop problems today. I've had the phone since Feb 29th and not had a problem with it yet, but today it started boot looping. I went into recovery and did a factory reset, was alright for a couple of hours then it crashed, started bootlooping again. Running stock 4.0.2 unrooted, I'm wondering if flashing 4.0.4 might help.
I'm in the same boat.... unrooting stock 4.0.1 firmware - canadian version from Negri.
April 23rd my phone crashed and started boot looping. Google logo - reboot - Google logo - reboot
Factory reset worked. I installed less apps than I had before figuring perhaps an app was corrupting something.
Yesterday - it happened again. Phone crashed. Boot loop. Factory Reset worked. Installed even fewer apps.
We'll see what happens this time around. I am hoping it is just a software thing. Hoping 4.0.4 gets pushed soon too.....
I've been having the same issue, plus sometimes my home screen it would lock up and wouldn't let me do anything, so I did a battery pull and it would boot loop for a half hour.
After the 3rd time I just took it to my Verizon wireless store, and showed them the situation and they couldn't figure it out, so their sending me a replacement, which I'm not looking forward too, don't want a semi-used phone....
Via Galaxy Nexus [LTE]
Rebooting Issue Solved.
I was also a troubled Samsung Galaxy Nexus user and my phone kept restarting more than half a dozen times everyday. Most of the times when I switched between two or more applications, or when it was simply idle on my desk.
However, I found a solution (at least in my case). All I did was root my phone, install cwm recovery, and flash a custom rom after wiping cache and factory resetting the phone, It's been about 5 to 6 hours now since I flashed the custom rom and I haven't had a single reboot or hang since.
Others who face this problem, please give it a shot, who knows? You might save your Galaxy Nexus instead of sending it back to get a replacement or spend some money on it for repairs which aren't even required in the first place.
I also had this problem unrooted. I had to give it to Samsung for the warranty
Swyped on my Galaxy Nexus running AOKP with Trinity Kernel, overclocked to 1.4GHz
I got my nexus yesterday, almost immediately after first start it start to install JB from OTA.
I did buy 2000mAh samsung original battery and started straight with it. not even testing with 1750mAh bat.
after installing JB and needed softwares, it started to randomly reboot.
it rebooted even it was just in my pocket.
sometimes when I did do something, display freezed and after about 5sec it rebooted.
Now I did changed to original 1750mAh, and it havent boot at all couple hours, even I did play angrybirds space.
I wont dare to root it before I am very sure problem is with 2000mah battery.

I could be wrong, but have you tried to clean the pin on the battery? Seems like battery and the phone isn't contracting too well
Swyped on my Galaxy Nexus running AOKP with Franco Kernel, overclocked to 1.4GHz
Little update, phone did continue rebooting with original 1750mAh battery also.
I did also reset with recovery mode, and after that it did also reboot one time.
like it uses all memory/cpu and when nothing to do reboot (like windows )
I also did flash stock rom with toolkit but no help.
I will test rooting phone and flash another rom, or is it useless ?
after using couple days, not yet rooted.
Phone works and wont reboot even in heavy stress. but sometimes it just reboots by own not a single program in task list.
might reboot right after previous reboot or take hours to reboot.
stupid phone
I have been done some research.
I did one more time reflash google stock with rootkit, and forgot lock phone, it was almost 3 hours by own in wifi, no reboots at all.
when I noticed that I forgot to lock it I rooted whole phone and installed paranoid android 2.13 with CWM.
Now Ive been using 2 hours without any reboot, installing software, setting things up and using apps.
I dont understand at all:silly:
edit: noup, yesterday evening one almost reboot, paranoid android did reset itself but didnt even reset uptime. so I didnt count that normal reboot.
but after wake up this morning, it did reboot once when I put in my pocket, another just lying on table, once activating bluetooth in my car.
going to send it back to seller.
I have a similar issue, although not quite the same. Last night my phone started boot looping - it managed to boot up to the lock screen, and I can use it for about a minute before it dies and then reboots. This continues again and again (I have to pull the battery to quit it).
I have stock JB on my GSM GN, but rooted with an unlocked bootloader / CWM. I restored my old CWM backup, and had the same issue. I also wiped the cache and the dalvik just to see if that helped, but I had the same issue. I then tried to do a factory reset in CWM, but after I did that the boot loop just got to the nexus logo and died, entering a new (slightly shorter) boot loop. I went back into recovery and reflashed my CWM backup, and that at least got me back to booting into android.
I can't understand what's going on - could it be a hardware issue if it will happily stay alive in recovery, but dies after 1-2mins of android?
Thanks for your help. If it is hardware then I hope I can reflash the stock recovery / bootloader and unroot through recovery... the phone doesn't stay on long enough to do it when it's booted into full android!
Well, guys was doing pretty well there for a second, I had just installed CarbonROM, was tweaking to my heart's content. Flashed a bad file in an attempt to improve speaker clairity, and boom stuck on the HTC boot logo.
Popped open the back, unplugged the battery, rebooted into HBOOT, rebooted into recovery and attempted to restore one of my backups I took right before flashing the bad zip. Failed. Can't load the data partition.
Ok, got the RUU file from this thread: http://forum.xda-developers.com/desire-816/general/ruu-htc-desire-816-a5chl-ruu-file-t2920254
Downloaded, put on root of SD card, renamed, rebooted to HBOOT, it picked it up, seemed to flash it, but it also seemed to go faster than it should. I'm suspecting it failed as well.
So now I've just got my phone sitting in recovery. Unable to mount the data partition.
Any clue on what I can do now? Hoping I haven't bricked this sucker...
Ok, my persistence paid off....Mods feel free to close this thread, I came up with a fix.
For anyone else in the same rut, this is how I fixed it...
Downloaded stock recovery from this link: https://drive.google.com/file/d/0B4NAwrQOaS7QVkxFYnhFZmhjOGc/view
Flashed stock recovery from Fastboot.
Loaded into stock recovery, key combo'd Volume UP + Power, got to the menu. Did a factory reset. Guess it reset partition mount points or something.
Rebooted to Fastboot, flashed TWRP, rebooted to recovery, restored a backup, and bam I'm back!

Yeah, note to self, never get a phone without a removable battery. The sticky pads under the back cover while I was popping it off were annoying. Thankfully my phone was only down for a few hours.

This phone has a non-removable battery. You don't need to take out anything, all you do is hold volume up + the power button for 10 seconds or more. It will ALWAYS hard power off no matter what state the phone is in.
Also, what file did you flash over to improve the speaker clarity which broke your phone? I spoke to you about this earlier in my CarbonROM thread. I actually was able to fix the boomsound issue and there is no more crackling in my speakers. I'm going to post how to do it when I get home.
Edit: SORRY! Volume UP, not DOWN. Got mixed up

I tried Vol Up/Down + Power for at least 30 seconds, was just stuck at HTC logo screen and I could feel the phone getting hotter so instead of having it run down the battery I decided to pop off the top. The back is meant to be non-removable but starting at the SD/SIM slot...slot, a guitar pick works great to undo the clips. Used a credit card to separate the sticky pads from the back. Pulled out the battery cable from the mainboard and reseated it, started it back up in HBOOT.
I flashed some sorta ZIP that's used with the HTC One M8 phones, figured if they have BoomSound it'd help too but noooope, haha. Can't remember what it was called. Did a lot of searching, tried Viper4Android, that sucked, tried tweaking the DSP, nothing came close to the original.
Sharing my own bricking experience
I'm a newbie, but I wanted to share my own experience from a few days ago. I bricked my VM/USA 816 when I was restoring a ROM backup of CM12 over a stock ROM. I was stuck on the CM12 blue "alien head" boot screen. I tried to get into the recovery screen by holding down power & volume, but it would only reboot and load CM12 again and not TWRP.
After a couple of hours of trying to get into recovery and deciding not to wait for the battery to drain because I thought the blue CM12 logo might burn into the screen. I decided to try to remove the cover and unplug the battery. I started at the SIM/SD Card slot trying to pop the cover off a little with a small screw driver to get a credit card(CC) between the cover and phone. Once I got it started I moved clockwise(cover side up) around with either a bent CC or a smaller cut up piece of CC to pop the tabs. I wasn't very gentle since I knew I wasn't going to return the phone and I bought the phone from VM with account balance so I didn't feel like I was really going to waste $300. Thank HTC the plastic cover is very forgiving. Once you get past the HTC logo you have to worry about the sticky tape around the bottom half of the phone where the battery is located. The bent CC was the best tool here and as I said earlier I wasn't very gentle while pulling off the cover once the tabs were loose.
Once I had the cover off I didn't know how to unplug the battery connector so I decided to pry the battery out. Once I did that I could see that the connecter pops up. I plugged the battery back in but the phone tried to load CM12 again. I don't remember if I had to press power button to turn on phone or it started when I connected the battery. I got back into the same state as before with a boot loop with no way getting back into recovery. So I unplugged battery again and connected the phone to my PC. I could see the screen the flashing between the charging screen and TWRP, but I couldn't get into recovery with buttons or screen touches. I then went into a command window on my PC to try the adb command. First I did a "adb devices" then I did a "adb reboot recovery" to get into TWRP. Once in TWRP I did an advanced wipe and installed CM12, gapps and supersu again from my ext SD Card. I'm not sure but I may have done a format of the internal storage just to be safe. Once I was up and running again I replaced the cover starting again clockwise from the SIM/SD Card corner and all the way around the phone till you get near the SIM/SD Card slot and have to replace the flap which is held in place by the cover/phone.
I hope this helps anyone who runs into the same problem.

You have to flash and use CWM 6.0.5.1 and wipe the same partitions that were backed up in your STOCK nandroid backup.
Once you do this, reboot to hboot. Enter fastboot. Flash the stock recovery. Wipe the data/cache/dalvik. Reboot and go to hboot again. (Your device won't be able to boot yet.) Enter fastboot again.
Flash CWM (ONLY CWM) and make sure it flashes by flashing it twice back to back without leaving fastboot at any point.
Boot into recovery and once loaded reboot into hboot once more then go once again to fastboot and flash Philz Recovery with the same double flash process.
Now boot into it, mount as a USB and create a clockworkmod/backup folder on the device root directory since Philz Recovery doesn't use the buried part of the system like CWM.
Drag and drop your stock root nandroid backup. Use Philsz recovery to restore it. Boot up and your phone will boot after 3-5 minutes.
Flash back CM11/12 if you'd like.

Hello
Thank you for sharing your solution.
I have a problem which is described in this thread: http://forum.xda-developers.com/des...im-boots-fastboot-t3316255/page3#post65409302.
My questions to you:
1. My bootloader is locked. Is it possible to flash stock recovery on it?
2. I tried to flash official rom but I received the message "Partition update fail!". Can what you did, resolve this problem?
I'll start from the beginining.. Okay so since i bought my tab (3 months ago) i had a battery problem, but it wasnt a bad battery problem. Once it got to 95% battery it stopped charging. Anyway, about a week after that i was unhappy with the performace of touchwiz on my tab so i decided to root it and install the cyanogenmod 12 nightlies. I was happy with cm for a while but eventually i got bored of all the bugs and instabilities so i decided to switch to a touchwiz rom.. This touchwiz rom was a vast improvement from the stock touchwiz so i decided to keep it. However i still wanted to improve the performace so i researched online for apk's/zip's that could improve my tabs performace. I came across crossbreeder and people said it was really good so i decided to install crossbreeder through TWRP. Once installed i rebooted my device and i instantly found many more battery problems. For example my battery would go from 50% to 20% in 5 mins/my battery would run out and i would reboot it and it would have had 40% etc. I downloaded some battery calibrating apps and calibrated my tab. After all that, that battery wasnt so bad. It was still dodgy but no where near as bad as it was straight after installing crossbreeder. Anyway, this was about 1 month ago. Since then, no new problems had occured with the battery until last night. Last night, my battery ent don to 1% then turned off like it should. I put my tab on charge and rebooted however when it rebooted nothing would work. My touchscreen didnt work, my home button didnt work, none of the keys next to the home button didnt work. So i thought that this was no problem and i could just boot into TWRP, factory reset and install the backup that i made. When i tried this, i booted into TWRP successfully however i couldnt press any of the TWRP buttons, again, i thought that this could be solved by flashing the stock firmware through odin. I put my tab into download mode and connected it to my pc, then flashed the stock rom. Once finished it showed a 'pass' and i thought everything was sorted.. When my tab booted up, it again, didnt let me press anything and none of the buttons would work. This is when i panicked. I then went into the stock recovery to factory reset my tab to see if that would work however, when i went into stock recovery, i couldnt go up or down using the volume keys.. So my volume keys didnt work either. I next put my tab in download mode and connected it to my pc. I opened odin and checked the 'Nand erase all' box thinking this would fully reset my whole tab. I then researched the 'nand erase all' function to find that everyone said that it breakes your device and puts it in bootloop etc. After reading this i instantly disconnected the usb from my computer to my tab. I tried rebooting my tab to see if it still booted and it didnt.. (i waited 20 mins). I then ran odin with 'clear efs' box ticked on. Again it didnt boot. I went into stock recovery again to see if the volume keys would work.. they didnt.. Infact when i opened stock recovery it had 3 errors showing (which it didnt last time i opened stock recovery). They all started with 'failed to mount /data'. Now i am here.. Sorry it was such a long read, i thought it would be better if i explained in detail. Thanks to anyone that replies/helps me.
NAND Erase All shouldn't destroy your device. What you need to do is boot into recovery, and choose the Factory Reset/Wipe Data option. From there, reboot and you should be good! Otherwise if it doesn't boot, just flash in Odin again, reboot to recovery, and then Factory Reset/Wipe Data again. We'll get you back up and running in no time
The reason why you are getting those errors is because your data partition is NOT formatted (because NAND Erase All wipes out your partition details, so it looks unformatted), so the recovery and your kernel are not finding your data partition. Your device will be unable to boot without. Factory Reset will reformat your data partition and get everything into place. Let me know how it goes!
