[Q] Weird softbrick - phone reboots constantly after factory reset - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Ok, so I think I may have finally killed one of my S2 Skyrockets.
I attempted to use the factory reset function from within Candy 5.1.1. However, on reboot the phone entered TWRP, or rather tried. Instead of booting into the recovery, it just kept restarting over and over again. I couldn't get it to boot into the OS or TWRP.
Thinking I had just soft-bricked it, I went into ODIN mode and uploaded a full restore image. Now I don't get stuck in a TWRP bootloop, I am stuck in a different bootloot. I see "Rethink Possible" go black, wait a few seconds, then it restarts again. I have pulled the battery out several times, attempted to boot into recovery (where I get the original TWRP bootloop) etc.
Is there any way to recover this device, or am I hosed?
[UPDATE]
Ok, this was one of the scarier things I've run into, but I recovered the phone. I used the sammobile version of the UCMC1 image (which blows away everything). This didn't reboot, it just hung. However, I was able to get into 3e (the stock recovery) and do a factory reset. THAT got me past the block. I'm now in the process of putting TWRP back on along with Candy.
Apparently you REALLY don't want to screw with the factory reset function...

Stuck in the bootloop :(

I noticed One+ was a bit slow so I decided first to switch from power save to balanced and it was still going slow so I decided to do a reboot. After the reboot the phone got stuck at the boot animation. I can get into recovery tried a factory reset didnt help. Im wondering if i try flashing the OS if that would work. Plus what would be the best way to do so.
What ROM, Kernel are you using?
Switching from Power Save to Balanced shouldn't cause your phone to be stuck in a boot loop. Something else caused it.
Everything is stock, it was really weird I was considering maybe using adb to flash a stock img (although i have little experience doing that). I tried rebooting again to potentially start this process (this is after a good 5 or 6 reboots and a factory reset) and it started up to the welcome screen. Another side issue it seems like the factory resets for this device only wipe the apps + user data. I know if I was rooted i wouldnt expect the media to be wiped but its stock with the stock rom. I bought it off ebay and when i went to load my stuff i did a factory reset and noticed the previous owners data including call/text logs and contacts were all on the device

If you were to flash a stock image, it would be done in fastboot mode and not adb mode. So is your phone booting yet?
You can always adb sideload a custom ROM and flash that to get your phone to a bootable state again.
The phone booted up after a good 3 hours a factory reset and multiple reboots

[Q] Having some major issues with my phone, help?

- A few days ago my phone freezes while I am using it, and its stuck on the google screen. at this point, it's on 5.0.1 unrooted, unlocked bootloader.
- I try going into recovery and wiping cache and doing factory reset. I keep getting errors but eventually the wipes work. Still doesn't boot though. So I do this a few times. I got it to boot twice but both times it froze within 5 mins and back to the same thing.
- I fastboot 5.0.1 factory image, goes through. but still no dice - stuck on google boot screen.
- I research and find out about the infamous power button problem. it doesn't seem like thats the issue with mine because the buttons seem to work fine. whatever, i take it to a local repair shop (phone is out of warranty) and the next day they inform me that there is no physical issue and that their software reset worked. they used the LG factory firmware way of resetting the device.
- Got the device back, used it for a while. It was fine for the time being but it was on 4.4.3 and I got the 4.4.4 update. I go and unlock bootloader, flash 5.0.1 factory image and push TWRP+root.
- Doesn't boot again, stuck on google logo
- I tried a whole bunch of stuff and nothing worked. I ended up with flashing 4.4.3 factory image in fastboot and relocking the bootloader so I could take it back to the shop the next day. At this point the phone wasn't even turning on.
- The next day (today), I tried turning it on, nothing. I put it in the charger for a while, then turned it on.... and it booted! used it for a while, it's fine.
- Did 4.4.4 system update, it's fine.
- Unlocked bootloader, it's fine.
- Tried to flash 5.0.1 factory image and again same issue - stuck on google screen.
- Been dicking around the last few hours trying to fix it ended with flashing 4.4.3 again but same issue, I then put the phone into download mode and connect to the computer but I got a green screen something about DemiGod Watchdog HW reset. I did the reset.
- Phone booted up again! Did the 4.4.4 system update and then it started freezing and rebooting withing few seconds of use. Now it's back to being stuck on google screen.
- I am obvious gonna bring it back to the shop now but any idea as to what is happening here?

1.I presume the "DemiGod Watchdog HW reset" green screen came up after you gave the phone for HW servicing? If so then they could have knocked around the parts a bit to cause a hardware issue(not sure what causes it)
2.Check the MD5 of the 5.0.1 factory image.
3.Instead of factory image use the OTA zip file and flash in stock recovery.
So I used the LG tool myself to flash the firmware (4.4.3 is the only one available) and it worked fine. Updated to 4.4.4. Fine.
I then adb sideload the 4.4.4 - 5.0.1, and stuck on google logo again .................im pulling my hair out this is so weird.

1) yes this was after.
2)i tried adb sideload.. ill try that good idea.
can't flash ota.zip in recovery. only adb and that didn't work.
think i'm just gonna hang on to 4.4.4 then for now. tried everything.
Just an update. I was running 4.4.4 just fine but the phone froze and went back to the Google screen again.

[Q] Hard Bricked, Security Error Boot Loop D800 after Lollipop OTA attempt.

Hey XDA,
I have a D800 that is totally stock. I have no custom recovery, and have never rooted the device.
A couple days ago I got the notification for an OTA update. I hit the notification, and rebooted the phone. It started the update process. It got through the first step. When it started the second part of the update, a black box popped up, and a code like "ERR 0x04ff" or something like that popped up. The phone rebooted, and got stuck in a boot loop with a "Security Error." The phone will boot up, show the LG logo, then show a slightly different LG logo with "Security Error" underneath it, then reboot and start the process over. I started messing around with the power button and volume keys to see what different modes I could boot it into. Initially I could boot it to the Factory data reset screen, the Hardware Mode Keys screen, and I got it into Download mode once. I didn't have any of the software or files available at the time to do anything with Download mode, so I opted to try a Factory reset. The phone attempted a Factory Reset. The little android with wiggly ears, and the spinny cube thingy popped up for about 4 seconds, and the phone rebooted.
Since trying that initial Factory Reset, I have been unable to get the phone into Download mode. I've tried doing the Factory Reset multiple times to no avail. I have not seen fastboot at all.
At this point, the only thing I can do with the phone is boot it to the Factory Data Reset screen, and to the Hardware Keys Mode screen. It will not do a factory reset. The android pops up for about 1-2 seconds, and the phone reboots, and goes right back to the boot loop with the security error.
I'm at a loss at this point. I've called AT&T, and unfortunately my phone is out of warranty by about 3 weeks. So they can't just mail me a replacement. Does anyone have any ideas? I can't seem to get it to be recognized by my PC, on Windows or Ubuntu. I get the feeling that it's just hard bricked, and there really isn't anything else I can try.
Any suggestions would be greatly appreciated
TL-DR: Totally stock D800, no custom recovery or root. Security Error Boot Loop after OTA attempt. No download mode or fastboot, factory reset is ineffective. Not recognized by PC. What do I do now?

Thanks for the reply. I was about to reply saying my phone wouldn't go into download mode, but then I randomly decided to use a different usb port, and now it went into download mode.
I'll give it a shot now and see what i can do
Ok, It seems I'm back up and running. I followed this guide http://forum.xda-developers.com/showthread.php?t=2432476 which re-flashed me to 4.2.2. I'm going to try and upgrade using LG PC Suite from my laptop, and see if I have better luck this time.
Lesson learned, try every USB port when trying to boot into download mode.
Thanks for the help

S6 failing to boot - stuck on factory reset

Hey, my phone has been playing up and generally malfunctioning lately. It seems to work fine for a day or so before freezing, and either rebooting itself or forcing me to manually reboot it using power + volume down. This seems to send it into a bootloop where it generally freezes during the Samsung animation with the pulsing squares. This sequence continues with me manually rebooting, also trying to boot to safe mode and to recovery and after various attempts, i successfully got into recovery without it freezing on the blue android.
I then decided to factory reset as a last option, having looked around on forums for solutions. However, I now do not know what to do as it seems to have frozen during the factory reset. I dont have screenshots but the script reads as follows :
dm-verity verification failed. . .
-- Wiping data. . .
Formatting /data. . .
Formatting /cache. . .
It has been on that for the past 30 minutes and so i have assumed it has frozen. I'm afraid to force another reboot in case it is accessing memory, any suggestions on what to do?
It is up to date on fully stock software, has never been rooted and i have never attempted to do so. Also only around a month old.
Any help would be appreciated, thanks
I did not try to perform a factory reset yet, but my S6 shows the same instability issues.
Random self reboots with getting stuck at the boot animation.
I furthermore cannot enter the stock recovery mode (get stuck at full cyan screen with android logo), only can access the ODIN mode atm.
Booting that device atm is a hit and miss.
(everything stock, never touched that device in the XDA way! )
Update: I had to repair my S6 as instability increased even more.
Samsung licensed repair shop exchanged the mainboard of my S6.
All is fine again (except wireless charging, but I guess they broke it while repairing)

Wokeup to my phone stuck in a bootloop... [SOLVED]

UPDATE: I have finally managed to get my phone working again! Am now currently re-downloading all my apps and transferring all my files back to my phone, running AOSPExtended (https://forum.xda-developers.com/oneplus-one/development/rom-aospextended-rom-t3732194) with OpenGApps. I'll write the steps I took to figure this mess out at the end of this post for anyone who might encounter the same problem in the future. :good:
So last night I left my phone charging overnight from 54% as I was downloading a couple of files (my internet is 1Mbps or 125KB/s). I've done this a couple of times before with no problems what so ever. But this morning I woke up and my phone was in a boot loop. I've tried everything I can think of and everything I could find on these forums, but to no luck. I am at my wits end and I have no clue what to do except to do a full factory reset, which I'd rather not do as its been a while since my last backup and I would lose a lot of precious files...
My Phone: OnePlus One 64GB Sandstone Black, purchased in August 2014.
ROM: cm-13.0-ZNH5Y-20161105-STABLE-Sultan-bacon
Recovery: TWRP+3.0.3-2-TugaPower
Firmware: bacon_firmware_update_2016_1-25_.4.0.1.c7-00011
The boot loop itself is odd, I'll describe them separately here.
-I can boot into fastboot, but not while the USB is plugged into my PC. I have to boot into fastboot, followed by plugging it into my PC. If I try to boot into fastboot while it is plugged in, the screen goes completely black and goes back into the bootloop. However, the phone shows up in Device Manager during the black screen.
- I can boot into Recovery, but the phone automatically reboots and goes back into the bootloop after a few minutes. One thing I have noticed is that if I let it reboot by itself, all the settings reset (including the confirmation to allow modifying of files when you first boot into recovery). But if I manually reboot back into recovery, the settings remain the same; atleast until it reboots automatically again.
Here, I'll list the things that I have tried to no avail:
1. Following this post - https://www.reddit.com/r/oneplus/comments/3izejg/so_youve_just_bricked_your_oneplus/, when I try to wipe Dalvik cache and cache from recovery, the phone goes right back into the bootloop
2. I tried flashing a newer version of TWRP (3.2.1-0 and 3.2.1-K2). After flashing I try to boot into recovery but the TWRP loading screen displays, and then goes right back into the bootloop. It wont even let me into the main menu.
3. I tried flashing a ROM through fastboot (via this post, https://forums.oneplus.net/threads/guide-oneplus-one-flashing-fastboot-recovery.301131/). The phone still remains in a bootloop.
HOWEVER, if I flash my previous recovery (TWRP+3.0.3-2-TugaPower replacing the stock cyanogen recovery from this method), my phone manages to get past the 1+ screen, and goes through my custom power on screen, and reaches the "Android is starting... Optimizing app 1 of 67." But it never gets past app 1, freezes, and then reboots. So now it's stuck in this "extended" bootloop thing.
What I want to know: is there anyway to fix my phone, or will I have to lose all my data and do a full factory reset through the ColorOS method? If anyone has any experience with this or knows a way to help, please don't hesitate!
Thank you in advance.
WHAT WORKED FOR ME:
After following the steps in this post (https://forums.oneplus.net/threads/guide-oneplus-one-flashing-fastboot-recovery.301131/) my phone was booting up, but was kicked back into a boot loop after freezing at the "Android is starting.. Optimizing app 1 of 67" screen. However, the recovery was now the default CyanogenMod recovery. I then re-flashed my previous recovery (TWRP+3.0.3-2-TugaPower) from fast boot, and it was now stable (no more auto-reboots). From there I made a backup off all my files onto my PC before proceeding. After that, I did what this post said (https://www.reddit.com/r/oneplus/comments/3izejg/so_youve_just_bricked_your_oneplus/) and wiped Cache + Dalvik cache. This allowed me to boot all the way past the "Android is starting" screen. However, the phone was still rendered unusable as there were non-stop notifications saying various apps had stopped working. I then booted back into recovery, downloaded and pushed a new ROM and GApps package on to my phone, wiped system, data, cache, dalvik cache, and installed the ROM and GApps pacakge, clearing the cache one more time before rebooting. Everything is working beautifully so far and I could not be happier! I hope this helps anyone else who encounters this problem, Cheers!
