[Q] Captivate Boot Looping Help

Hi I've searched some, and I haven't found anything for this setup. My captivate was working fine when I last used it a while back but when I turned it on, for a few weeks now, its been stuck in a boot loop. The problem is that I have never flashed custom roms or anything, its just been its stock- update as officially released,etc. Also, aside from that, I don't have any backups of anything because of computer issues. Is there anything I could do to just get it going again without chancing loosing all of the pictures I have on there?

Can you get to Download and / or recovery modes?
You could try a Factory Reset from recovery. All that I have read says that it does not delete pictures and music. You are likely to loose apps you have downloaded and the app data. (Double check to insure this is correct.)
If a factory reset does not work things get a bit more complicated. For example, you could possible move files from your phone to your PC using adb if you can get to download mode.

From what I've still been researching, anything factory reset is supposed to completely wipe everything on the phone. Is there any way to backup or get anywhere with download mode, because I can get into download mode, but it doesn't register with my computer so I don't know what I can do from it.

Possible brick after build.prop edit. Verizon LG G2

Hello,
I've been rooted for a few months now and have never had any problems. I wanted to use that Milk Music app from Samsung so I followed the instructions and was able to get it working on my phone and have been for awhile. I recently decided it would be a good idea to change the build.prop file back to its original state, so I copied and pasted it in using Root Browser. (I had made a backup file stored elsewhere). Once I did that I rebooted my phone for the changes to take effect. After I did that I cannot get my phone to turn back on. It displays the LG animated logo screen and then goes completely black. The light on top of the phone radiates blue/green. I've read through several forums about this issue and have tried everything in order to get it to work and for some reason, using my computer and ADB always gives me an error: device not found. I have installed the drivers and everything. Anyone else run in to this problem before? I would really appreciate it.

If you are on stock rom, just rooted. I would think you should be able to factory reset through stock recovery.
Confirm the process but i think you power completely off. Then hold volume down and power at the same time when you see the lg logo release both buttons then press both buttons and hold them.
Should take you to factory reset.
Not 100% certain but this will probably be your next step if you can't get a computer to see it.
Good luck

The factory data reset didn't really change anything. For some reason I cannot boot into recovery mode either. I can put it in download mode though, but my computer still has a problem recognizing it.

If you can get into dl mode then you should be able to return it to stock which should reset everything. Returning to stock has its own downside but at least you'll be up and running again.

[Q] LG L90 D315 bricked without recovery access etc

So this is my first xda thread. I spent hours searching without finding a solution for my particular case.
I am using a LG L90 D415 (T-Mobile version) and I got bored of it and so I started playing with the system (not the first phone I'm doing that with, so I know a bit about that sutff). So I tried to install the new Android L home launcher from here http://forum.xda-developers.com/showthread.php?t=2796019
I did everything like explained, installed it and changed the build.prop like described. But after I rebooted my phone, expecting a new home launcher, the phone boots, I am at the lockscreen, but after like 4 seconds I receive multiple errors (like gapps stopped working) and than everything freezes and it reboots.
Unfortunaly I didn't install a recovery or unlocked fastboot. So I can access download mode, but that's it. My computer doesn't see my phone (because usb debugging deactivated?) and so I don't know what to do. I think that's a pretty tough case but I hope some smart person can help me
Thank you

No custom recovery and no fastboot? Factory reset is your only option. See this post. Scroll down to Q14. Even though it's titled something else, the same button presses apply for your device in it's current state, ie; no recovery, no fastboot

First thanks for the fast answer. So I figuered that I only need to delete the build.prop file and replace it with my backup file. Isn't there any way to rescue my files and/or access the /system folder? I'm an exchange student now and I don't wanna lose my picture memories
And btw I know that I build the perfect worst case scenario right now
Oh and in the L90 faq it says that when you flashed a recovery and you navigate to factory reset it won't reset but boot into recovery. Does something like this work even without recovery, so I could try doing stuff with adb?

If adb isn't detecting the phone, no. There isn't any other way.

Unfortunately, no.
Factory reset will not erase your sdcard. It will however erase internal data. It will return the phone to the state it was in the first time it was powered on.

[notice] please read!!!

They say once your device is turning on, its not a hard brick, well explain this. My motorola Nexus 6 won't boot, when I try to power it on, it shows the Google logo then shuts off immediately. When I plug in the charger from a complete power off, the white battery sign keeps flashing, it shows for 1 second then shuts off then repeats the cycle of showing the battery sign then shutting off. It boots into bootloader/fastboot mode fine, and I have tried flashing the factory image, forced flash each partition individually, YES ALL OF THEM, YES I HAVE THE LATEST SDK YES THE LATEST FASTBOOT AND ADB, YES I CHECKED THE MD5 OF THE FILES, YES I USED DIFFERENT CABLES PORTS AND COMPUTERS. it flashes fine in terminal all the files go through with result ''OKAY'' but it still shuts off immediately while showing the first google logo after i reboot. It won't even boot into stock recovery after the flash, it just shuts off after the google logo. i tried with costum revovery same result. i tried 5.0 LRX210 and 5.1 LRX22C. This isn't my first nexus, in know that flashing factory image should fix 99% of issues, ive been flashing phones and rooting for years and i know that nexus devices are somewhat impossible to hardbrick. i made sure to exhaust every option i knew of before posting here, Ive tried the toolkit and its options countless times ive had many sleepless nights now over this. Please help.
P.S I didn't purchase officially from google or Motorola, I bought it for $580 from a guy who claimed he bricked it trying to install a font pack ''iFont'' so I figured let me buy it and restore factory image, easy win. Didn't work. He said he rooted it, installed custom recovery and euphoria os rom. Then he installed the fontpack, it told him to reboot to apply changes, and when he rebooted it wouldn't boot past google screen after that. not even to the boot animation, It just shuts off. When its off and u plug in the charger it does the same thing, you just keep seeing the charging symbol over and over because its constantly rebooting. Its a T-Mobile Nexus 6 BTW, model number XT1103. I am now looking at a motherboard for the nexus 6 on ebay which is $300, as this is the only thing i see left to do. Please any help would be appreciated. I can promise a hefty $$$ reward for any individual that helps me recover it to a working state.

I think they say as long as you can get to the BOOTLOADER it's not a hard brick. But as far as the issue itself, I have no idea. You said you flashed the factory images and it still didn't help?

U manually flashed the images correct? Any errors when flashing? Are you using the flash all bat script or flashing each file separate?

Its all BS, there's not really such a thing as a soft. A Brick is a Brick. If your phone is bricked, the only fix is to send it for repair so the manufacturer can fix it. If it can be fixed without doing that, its not a brick.

If it can stay connected while flashing. Does it reboot when connected like charging and stay in bootloop?

no.
but after flashing the factory img, you might have to wipe data for it to boot.

NONE of this suggests that your phone is a brick. In fact, it all proves that it is NOT a brick.
*which is not to say that it isn't BROKEN.
"i tried with costum revovery same result. i tried 5.0 LRX210 and 5.1 LRX22C"
Let me ask you this; did it reboot when you booted into a custom recovery? If custom recovery worked, then it seems like the unit can still be saved.
BTW: LRX22C is also 5.0. Specifically, 5.0.1. 5.1 is not available yet.
So a little bit of clarifications first;
HAVE you tried to perform a factory wipe (via recovery) or otherwise FORMAT (not "fastboot erase") the data and cache partitions? No part of your message mentions formatting the data or cache partitions. If the init is unable to manipulate/mount a possibly corrupt data or cache partition (or possibly some other partitions as well), then it WILL REBOOT.
In addition, some logs of the reboot could be useful if you are able to obtain any. A somewhat modified boot image can enable adb and kernel logging at a point from before the reboot occurs.
P.S I didn't purchase officially from google or Motorola, I bought it for $580 from a guy who claimed he bricked it trying to install a font pack ''iFont'' so I figured let me buy it and restore factory image, easy win.

I don't think you need a new mainboard.
If what he explained to you is correct, then my previous about fixing corrupt data partitions should solve the issue for you.

Agree with the guy above me. Same thing happened to me on my Nexus 9. Manual flashes all successful but could not boot. Booted into recovery and did a factory wipe and all was well. I know this is the nexus 6, but it sounds like corrupted data.

NEED HELP - Android gone black

Moto X 2014: unrooted with bootloader unlocked. It's running Stock 5.1 and I haven't messed with anything on it. I gave it to my Dad after a few months of using it, so I factory reset it and gave it to him, 2 weeks later he tells me it has stopped working. It boots up normally, but from then on it is black, I can access minor parts of the OS such as the power off menu, the camera (by shaking) and Moto Display, but everything else doesn't work. I have never seen anything like this before, and I am well accustomed to flashing custom ROMs and rooting Android. If it comes down to it I will factory reset it or flash stock, but I can't even plug it into my PC and retrieve any files. Anyone have any idea whats gone wrong?
I have attached a video demonstrating what's happened to help diagnose the problem.

If you search the forum here for "black screen" it has happened to other people as well on stock 5.1. Supposedly the fix is a factory reset.

Ok, It was just really surprising thats all. I will factory reset then. Thanks

I am having the exact same issue. Have you had a luck resolving it short of a factory reset?
My phone battery died last night. I plugged my phone in, let it get about 15% charge, then tried to turn it back on. The phone boots like normal, but after the boot animation goes away, the screen is black. Active notifications still seem to work, and I can hold the power button to get the Power Down option. I can boot into the bootloader & access recovery just fine. However, my phone is fully stock (no root, no bootloader unlock, no anything). I can't seem to access ADB when the phone is powered normally (ie, when I'm at this mysterious black screen), but it's possible that USB debugging isn't even enabled.
So far, I've found a few people who've said a full factory reset will fix the problem, but I'm looking for another solution, or at least a way to grab my data before I reset. Since my bootloader's still locked, I can't seem to use fastboot boot to boot into TWRP, and I can't find any other way to access my data to copy it off the phone. I've tried wiping the cache using the stock recovery to no avail. Any suggestions?

Unfortunately I couldn't retreive any data from the phone, I can confirm however that a factory reset does fix the issue. The Android automatic backup does work in the broken state so I did manage to restore my settings and apps. But the internal sd card was wiped upon factory reseting. Just an idea of the top of my head: Try running adb backup and see if that works, and then unlocking the bootloader, flashing twrp, restoring the backup, and finally transfering the internal sd card data to a mounted drive using twrp. Thats just a stab in the dark and i dont have the phone on me to test it. Give it a try and lets hope Motorola will fix this bug soon.

Ok, thanks. I did try adb backup, but adb won't recognize the device when it's "booted" & sitting at the blank screen, and the stock recovery doesn't give full adb access. I'm currently looking into the various data recovery options to maybe pull some stuff off after reseting. It's really only a few files that I need, so maybe that will work?

Unfortunately the internal SD card mounts using MTP and not like a flash drive, so using the usual methods through Windows to recover wont work. However you could try and restore your internal sd card using this solution: http://goo.gl/OKdV14
As for accessing adb through recovery, you could try this method: http://goo.gl/5T7bhq
Hopefully one of these methods should work, so you can at least recover some of your files.

I had the same problem today. I tried to backup a twrp backup I have made few weeks ago but I still had the black screen. The only solution is to factory reset...
Happily I could have saved my data when I was on TWRP. Anyone knows how to restore sms from the data I have saved ?
