Lingering EVO issues (SD Card, Camera, etc.)

I'm having some lingering issues with my EVO even after running OTA updates. I am running a rooted stock ROM, currently software version 1.32.651.6 (I have not attempted the latest OTA update yet).
In particular are two problems - SD card issues have remained even after the OTA update. This was present even before rooting but after installing the first update (I went to a "full-service" store on opening day and they set it up themselves, assuming everyone would want it - luckily I could still get root). Issues include the Camera application reporting permissions problems randomly when trying to save pictures to the SD card, HTC's music application freaking out and coming to a near freeze trying to crawl the SD card during one of its troublesome spurts, and files disappearing from file explorers. So basically run of the mill, pre-first-OTA sd card problems. But occurring after the update and both before/after rooting.
Second is a problem with the camera itself. When first booting, HTC's included photo/video application will instantly crash after showing the camera icon on the black background. Google Goggles freezes for about 10 seconds then reports it was unable to connect to the camera. After the phone being on for about half an hour, these issues (seemingly) go away until the next reboot.
Last, and least frequent but still troubling, is a problem with the device powering on. At least twice I have been unable to get the device to turn on after powering it off, forcing a pull and replace of the battery to get it working again.
As far as I know, all of these issues could be either hardware or software. Even the power problem - my best guess is that the phone never powers off fully, but is instead locked inside of a deep sleep state and thus can not turn on until a battery pull forces the entire system off.
The questions being - first, are there any known solutions to the above problems? I have found many threads in particular regarding SD card issues, but none that seem to report these problems post-update. The others I have seen little to nothing about.
Second - if there are not known solutions, would it be prudent to return the phone as it may likely be a hardware problem?
Since it seems I'm forced to take the last update if I get a replacement, I may likely have problems getting a full root back. I'd like to avoid that if possible - having root works wonders for doing application development using non-native (unexposed) API's (Which - side note - since I'm developing for 2.1 at the moment, other than hacking for direct access to a Surface, does anyone know of a _fast_ way to do direct blits from native code? glTexImage2d is insanely slow).
Thanks all any help. Again, apologize if any of these are solved and gone problems, but I wasn't able to procure anything myself.

I'd go for the replacement, sounds like a defective unit..
Be sure that the folks here at xda will get root working regardless of OTA.

replace the unit, i'm very particular about my phones, if there is anything wrong with it I replace it.

I too have the SD card issue, I have updated, i have rooted, re-rooted, flashed new rom, different roms (fresh and sd) and it has always given me the sd card issue. Sometimes it wants to be a pain and not work at all, sometimes its good for at least a week or two. I am waiting for a little longer to make sure when I get a replacement its a newer version.

SD card permission errors --- POSSIBLE FIX
I hope/think/believe I fixed this error for those interested, I use my EVO for work and need it to work without a hitch....
Here goes (**Note i am a noob with smartphones with a dangerous amount of IT knowledge - disclaimer for those brave enough to browse around the root files and SD card files; I am not responsible for you bricking your phone, I am only trying to help those in need and putting in my 2 cents_)
Download and open the app ---> Root Explorer (or any other root explorer for that matter) from Android market.
Once Root Explorer is open (look up top/left it will say) Mounted as r/o (means read only) - press the white button to mount it as r/w (read & write)
Press and long hold on the SD card directory (folder) - you will get another window from which you must select the permissions option.
Under top option USER - check all marks -- READ WRITE AND EXECUTE & click OK.
VERY IMPORTANT - Click on the (white button) Mount as r/o to write protect your root files on your phone again.
I just applied this fix about 45 mins ago and seems to be working......updates to come if issues persist or re-surface. (**Note I could not see photos or play music and some apps were also giving me FCs (intermittently) due to permission or write errors to SD card; and now it seems to be working like nothing ever happened.)
What I have ::: stock ROM on EVO supersonic with recent HTC updates applied - standard 8Gig SD card provided with phone / had rooted but put back stock ROM for preference issues.
Hope this info helps some folks...very frustrating issue.
Cheers

SD card permission errors --- POSSIBLE FIX
ONE LAST SIDENOTE COMMENT -
I transfer data to my PC often (running Win 7 32bit_)
It is crucial that you right click on "safely remove hardware" icon on the lower right side (next to date and time) and WAIT until windows tells you
..."It is now safe to remove your hardware" --- I was just taking the plug out when done and it appears as if that could have started or compounded these issues with the SD card.

I too get the could not connect problems at times. And I have lost access to the SD card a few times. Some say its Fring that causes the problem. But after removing it I still have camera issues. I noticed that having the LED Light on while trying to open the camera will cause this problem.
I am running CM6 RC1 so this is to be expected from Release Candidates. Sit tight. It will get fixed.

Well after a full 24 hrs...no issues with the read write error on my EVO SD card, I think that when the phone is removed from PC incorrectly (i.e. pulling USB cable out in mode other than "Charge only" i.e. HTC sync, Disk Drive, Internet sharing - it causes it to "corrupt" the permissions on the SD card - It is still working like a champ and i am waiting impatiently for my EVO Froyo update ... feedback appreciated for those whom tried this fix and had it work....txs

Hi there. So I followed all of your instructions above and downloaded Root Explorer. However, every time I change the permissions, they don't save. User, Group and Other is always switched off at root level. Do you think this may mean my SD card is corrupted?
I rooted it with BakedSnack.
I now want to un-root it as I miss taking shots, looking at my shots, listening to my tunes etc.
But I want to keep all my apps. All my texts and everything else. Whats the best way to go about this? I am also a bit of a n00b and I apologize if this is in the wrong forum, but when Froyo releases tomorrow (apparently) do I have to unroot to receive the update?
Thanks

My Note 4 Was Wiped, Any Way to Recover Data

First off, thank you for reading this.
A couple of weeks ago I went to use my phone. I typed my security code into unlock the screen and the phone froze. After a few minutes, the phone rebooted, and took a long time to boot, and came back to the "Welcome to Verizon" prompts you get when first turning on a brand new phone; it appears the phone went thru a factory reset! After getting thru the prompts, I found that ALL data on the phone and the external SD card was erased.
I tried to recover the files from the SD card by connecting the card to my Windows machine and running and my trusty recovery tools (which have always worked in the past on formatted drives). All the tools I normally use failed to find any files. So, I bought Wondershare Dr. Fone - and it actually worked on the SD card. It's not the greatest tool, but it was at least able to recover my media files. When Dr Fone attempted to scan the phone's memory it failed because it was not able to root the phone. After some reading, I see that it is not possible to root a Note 4 (Verizon). However, it appears there might be a temp root possible. Can anyone give me some general direction on how I can recover data from the phone's memory (I have more media that plus some other app-related files)? Will a temp-root allow Dr Fone to scan?
Thanks in advance.

From my experience, you could get help from professional app

Since your phone is wiped, you could apply to Samsung Data Recovery app. It works better if your phone is rooted. good luck.

[emergency] LG G3 - won't boot, can I save files before service takes it?

Hello,
I was moving files from the internal to the external card today when I noticed on some pictures it was slowing to a crawl and semi timing out. After it finished I checked them and most of them were corrupted. I proceeded to copy some extra files to the SD with no problems and I decided to reboot it.
It gets stuck on the LG Life's Good screen indefinitely. I tried removing the battery, going into the hard recovery menu, leaving it on the boot screen for a long time nada. It's still on warranty according to LG and they scheduled a courier to come pick it up tomorrow morning (~ in 22h). It might be the NAND is dying? or something else but most likely the data will be lost one way or another.
I am wondering if there is something I could try before they get it to make it work even for few minutes or if someone can tell me if & how - can I through the download mode backup contacts and sms somehow?
LG G3 D855
Stock Android 5.1 - never rooted
Thank you.

Can be closed, in my case the reason the phone was unabled to boot was the microsd. Only after ~ 2 years the samsung UHS-1 gave up :/

Bootloop issue HTC One M8 - wanting to avoid a hard reset to recover photos

Hi! So I'm currently having issues with my HTC One m8 as it started acting up recently when I was taking photos, it would crash and reset and continue this process if I opened more than two applications open. All of a sudden it crashed while I tried to back all my photos online and then would no longer switch on past the htc boot screen and would freeze in a bootloop. Ever since I have been unable to reach the normal screen of my phone to try and retrieve photos. In terms of resetting the phone manually that's easily doable and getting on to the recovery settings is no problem.
I'm trying to avoid a hard reset, and been looking online and saw something about using Fastboot USB, which I have currently on my phone screen while plugged in to my computer. Is there a way I can retrieve photos directly/indirectly from this before hard resetting my phone? Or should I bring it to the shop?
Any help is super appreciated!
From a not so tech savvy student

Is the phone modified (TWRP installed, root)?

It is not yet rooted no, should I root it?

No, that wasn't the point of my question.
With a modded device, you can access storage in custom recovery. Or you can also adb pull files from internal storage (I believe). You can't do either of these, if the phone isn't modded.
And you can't unlock the bootloader, and root the phone at this point. Unlocking the bootloader by definition, wipes all data on the phone (for security).
You are sure the save location is internal storage, and not the removable SD if you have one (internal storage is default)? If it is on SD, it will not be wiped. Probably not the case, but just mentioning it, in the unlikely event it is the case.
Otherwise, I don't think there is any way to retrieve the photos, unfortunately. You should be backing up your data on a regular basis, not waiting for a disaster then trying to retrieve the data. This comment assumes that it's all your photos you are talking about (no backup was done previously); and not just the ones taken since the last backup (since just losing a few photos is usually not a heartbreaking event).

Lost ALL images and videos - will rooting possibly save me?

Hey all,
as I was backing up files from my phone (internal storage full, 500MB to go) via USB, and after I'd done a bunch of PDFs and what not, I wanted to start moving videos / photos. That failed instantly and after that, EVERY SINGLE IMAGE / VIDEO file was gone from the phone. I installed three "recovery" apps - they couldn't find a thing. I have a bunch of family stuff I really, really would like to have back.
I downloaded the MIUI unlocking tool and wanted to 'get going' with rooting, but I'm getting a "Unlock will erase user data" notification, for if I continue. This does not seem what I want.
- Can I continue without definitely trashing any hope of recovering files?
- Is there another way to get to files that magically disappeared (no Sync on, no OneDrive auto-backup, no nothing at all) that do not required root, and/or ...
- Is this a "known" problem? I cannot seem to find anything.
Many, many, many thanks......

As MIUI Unlocking tool says, it will delete all the data on the phone.

Whelp, this is happening. I'll give it a go before I can't get the files...
I have to wait 2 weeks for the MIUI tool to allow unlocking the bootloader. So I guess at this point I'd mostly like to know if the Mysterious Case of the Disappearing Files is something that's more common on the Redmi Note 5 - or on Android 8.1 / MIUI? I'd like to assure the reader at this point that, while threads like these are a dime a dozen and it often boils down to user error, I'm not a complete nitwit and assure you I was doing nothing other than Ctrl-X -> Ctrl-V to harddrive, got an error message, 40GB were magically freed up on internal storage and ALL files were gone. All of it. Folders too.
Updating thread title, hope that's okay..

Realistically, considering different "undelete" / "recovery" apps are not finding ANYTHING!!! at all, how likely is it even that something will be found once the device has been rooted? This almost seems like it had a system reset while it was still enabled...... Just everything gone / re-encrypted / whatever. Is that even possible? Again, though, the device DID NOT reboot. The files were there......then 40GB was gone.

It is possible to recover the data but the process will require root permissions. Install Disk digger pro from playstore. And give root permissions it can easily recover the most of the photos ( May recover all but possibilities are less ) Give a try bro it will definitely help you. As it helped me before.

I had something similar back when I had Redmi Note 3. Files just disappeared when I put them inside obb folder. However, they reappeared when I entered the recovery (it was custom) and I copyed them via cable onto my pc. They weren't there when I connected normally turned on phone to the pc, and it was annoying. So whatever you are doing, don't format your phone, otherwise you'll lose the files forever.
If rooting and installing an app to recover the files won't help, I suggest you flashing twrp and trying to find them from there using the cable and a pc, or whatever.

Thanks. It's a shame I'm finally "getting in to" rooting only now, now that I have a problem. When I tried many years ago I felt it was too complicated and most of all risky....
The main problem I have with rooting is that the Mi Unlock Tool wishes to Reset the phone, re-encrypting it in the process, and destroying any hope of recovering data. I intend to flash OrangeFox before it can reset.... Does anyone have a better idea....? It's really very, very much appreciated!
