Recovering data from Bootloop?

Hi all,

First of all, my phone is completely vanilla, no rooting or modifications were done. Running 5.0

Here's my situation:
After fully charging the phone yesterday and sending some messages on whatsapp, I drove out to get food and while on the way there, the phone blacked out. At first, I was able to get to the colored dots loading screen but it would always get stuck there and shut off. Then I keep trying to restart it up and it got worse and worse, now I'm always stuck at the GOOGLE screen. I'm not sure if this is a boot loop issue as it just gets stuck at GOOGLE screen. I tried the recovery mode cache wipe and it gets stuck at the GOOGLE screen in the middle of the wipe, or blacks out.

So this morning, after fiddling around the power buttons some more, I am able to get the battery logo while charging, though it is weird that it shows 100% then completely drained the next minute or so. I try to load into the recovery mode again and this is what I see at the bottom

E: failed to mount /cache (invalid argument)
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: failed to mount /cache (invalid argument)
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: failed to mount /cache (invalid argument)
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: failed to mount /cache (invalid argument)

Am I screwed? I'm not sure what to do at this point.

Today, I am stuck at the colored dots boot animation but after smacking the power button side a bit, I'm back to being stuck on the Google screen. What's worse the recovery mode can't be maintained on the screen as it blacks out after 5-10 seconds. What can I do at this point?

I was going to use WUGfresh to reflasth the ROM but I think this wipe all data on he phone? Is there anything I can do at this point to retrieve all my apps, photos and what not? Nothing is backed up.

Any tips or advice would be greatly appreciated.

Thanks

Recovering deleted pictures

I accidentally deleted some pictures off of my ATT s6. I thought it would be easy to recover the pictures, but that does not seem to be the case. My phone has 5.0.2 android with a baseband version ending in OF4. The kernel is Aug 5th 2015. Based on my research it appears that my phone is currently unrootable? And root privileges are needed by any android app to recover the pictures? I also tried a windows app Wondershare Dr. phone for android, although it doesn't seem to recognize my phone. Any solutions? I know that I am running out of time since the pictures will be gone forever if the memory if used by other files. Thanks in advance!

Recovering Data from a Droid4 that won't boot

My droid4 won't get past the boot screen (red M).

It is stock, never rooted. Took it to VZW and the guy ripped the battery out WITHOUT unscrewing the two screws so not sure if it is creating a short.

I desperately need to recover my contacts and pictures. There was no google account on the phone.

Any ideas?

Need help recovering from bad flash

I was attempting to change my Galaxy Nexus from Cyanogenmod 10.2.1 to cm 11 (current stable release). So, I did the following:

1. Created a Nandroid backup, saved it to my laptop, and deleted it from my phone as after creating the backup I had almost no free space. Before deleting it, I did test it and confirm that it worked.


2. Downloaded the CM ROM and gapps from the CM website


3. Verified their hashes.


4. Copied them to /sdcard. I didn't think to verify their hashes again. This may well have been a mistake.


5. Used TWRP v2.6.3.0 to wipe the phone and attempt to install CM. A message appears: "Failed." Here's a sample output (note that the output falls off the right-hand edge of the screen and there seems to be no way to scroll it to make it readable):
   
   
   

   Code:

   
   

   ---

   Updating partition details...
Installing '/sdcard/cm-11-20150626-SNAPSHOT-XNG3
Checking for MD5 file...
Skipping MD5 check: no MD5 file found.
set_metadata_recursive: some changes failed
E:Error executing updater binary in zip '/sdcard
Updating partition details...

   ---

   
   

At this point, the phone won't boot. It goes directly to recovery.

To recover, I thought I'd just copy over my Nandroid backup. But, I can't use adb in recovery. I tried to use fastboot to flash my nandroid backup, but the format seems to be different, and I wound up with a phone that, when attempting normal boot, gets stuck on the Google logo until I remove the battery. I do have access to recovery still.

How can I get something bootable on my phone? I just want to restore my Nandroid backup. (And maybe see if I can figure out why CM-11 didn't work.) I can't find any way to copy arbitrary files to my phone.
