I've got a rooted (Super SU, but the original root manager was Superuser) LG C800 that I was having problems with. To be specific, I installed some apps on to the system. Some of these apps would be Titanium Backup for root, Avast Mobile Security, ROM Tool Box Lite, Super SU, and a quite a few others. From day one they seem to be kicked right back to my S.D. card, but not all at the same time, and some would stay on the system. I read where I should move the apps back to my S.D. card and try to re-install them on the system minus the data. When I did, the phone went nuts. Now it stays in a restart mode but never fully boots up. Can I salvage it, and if so, please tell me how?! I have tried the hard reset/recovery boot where you hold down the power button, volume, and a few other keys, but it did not work. I'm a broke college student and can't really afford to buy a new phone. I used this one for everything including tethering it to get my assignments done at home and turned in on time. Please help! I'm open to suggestions....... My phone will be completely off. When I plug it into my computer, via U.S.B., it automatically turns it on whether I want it to be on or not. Then it starts off in "reboot recovery" mode, will boot all the way to the point to where the home screen would normally turn on, but then it starts in that "boot loop" all over again but never fully boots up before going back to the beginning of that "boot loop" yet again. I can't even get it to register on my laptop as being plugged in. The reason I took the apps I placed on the system off was because sometimes when I'd re-boot the system the apps would be on the system and sometimes back on my S.D. card without my involvement of any kind other than rebooting my phone. Is completing a Nandroid recovery or re-installation of my ROM even possible with my computer no longer recognizing it as even being plugged in? From what I can tell it won't be. Am I fighting a lost cause or is it salvageable?
Rooted myTouch Q 4G, a.k.a. LG C800
I believe it has a 2.3.4 GRJ22-perf, and then something like 2.6.35.7? I can't remember off the top of my head, and I can't pull it up on my phone anymore or else I'd double check.
Have you tried booting into recovery?
(More about my phone from the original post) Honestly.........I'm not what you may consider technologically inclined. I have however done about as much research online concerning this matter as any one person can do. I've looked it up on all major sites, and many smaller ones too, that post remedies for phone, or "human" if you'd rather, malfunctions. They all talk about still being able to reach a home screen or doing the whole holding the power and volume decrease buttons until I "reboot recovery" screen appears (if that's what you're referring to as doing a recovery reboot as). Don't forget the one where you hold hold the power and volume decrease buttons along with the "A" and "F" keys as well. I even tried one from here where you're supposed to push the genius button after the Android figure leaves the screen. My phone won't allow me to do either. Basically if it's online, I myself, or this girl that's been staying with me, have tried it without any results. On the initial boot the Android figure and the box with the arrow coming out of it show up and it boots until just about the point that it use to switch over to the home screen and it will start the whole "boot loop" over again. The thing is though that the Android figure and box aren't there any other time after the first boot, and with every boot loop it makes after that, the time is reduced from the beginning of the loop to the end when it starts all over again. The phone won't shut off unless I remove the battery and even though my laptop no longer recognizes the device, when I plug my phone into it or another power source and it's off, it automatically turns itself on and begins that boot loop all over again. there is one thing I have yet to try. I read on one site where I could download a custom ROM on my S.D. and then try reboot it, but it never makes it to the point in which the files on my S.D. card are ran, much less scanned. I am still 100% open to any and all suggestions in the diagnosis of this issue. I may record and place a video on one of the more popular "tube" sites to better show or further explain what's happening and then come back on here to post the link?! Feel free to reply back if it's possible you can help before I'm able to complete that later this evening. And thanks for any and all help in advance to everyone.
My tablet froze on me and I powered it down to restart it and then it went into what folks on here call a bootloop. After holding down Power and volume down, it brought me to a screen that had three icons and I chose the one on the right by mistake and now it's looping again, but instead of the Asus screen with the refreshing icon, it's the android falling with an Error on his chest after quickly flashing Installing System Update.
The power volume combo works no more and the only way I can shut off my tablet completely is to use the power and volume up button. I can't get back to screen with the three icons no matter how many times I try.
I've already resolved myself to purchasing a new device, so my main concern is recovering the data, slim as that might be. Any recommendations?
Also, note that Ive never rooted or installed anything on my tablet. No roms or kernels or any other modifications. If I can get my data by any means necessary, I'd be satisfied, even If I Ihad to open it and retrieve the harddrive.
Hopefully Ive explained myself sufficently for you guys to help me. Cheers.

If I read your post correctly, you selected the right icon which is a Wipe data from your bootloader. When you executed that Wipe data, it will wipe everything on your internal SD including your /media folder or your personal files and data... The chance is very slim unless someone knows how to recover data from a wipe. Technically, your data is still there but it is only a dumb files which contain only 0's and 1's. Some recovery tools may be able to retrieve your data but I don't have that knowledge.. I hope that someone will be able to help you out and good luck...:fingers-crossed:
I'm afraid LMK is right: Your data is gone.
Do I suspect correctly that you interrupted the Wipe Data process after selecting it "accidentally"?
Choosign Wipe Data from the bootloader causes the BL to write a command to the misc partition to start the recovery and wipe the data partition. If you interrupted the process, there's no telling what and where that got corrupted - unless you just let it loop and pray that it finishes the wipe process which would erase the BL command. Connect it to power and let it loop for a few hours. What have you got to loose?
But your data is gone either way - sorry.
Morning, cheeky question(s)
Where are you located, and would you be interested in selling your bricked TF700? I have a broken screen among other things and would be interested in buying your tablet for spares if you are getting a new one?
PM me if you are interested.
Thank you
Freddie
I'm not all too sure what the Icon on the left wad, but I'm sure it said RKU or some sort. I would have given up all hope if I had hit the wipe data on the right.
Days recovery aside, is there anyway I can get my looped tablet to work? I plugged it into a comp and it didn't recognise it.
Hi, I got Motorola Moto G, original system, no root. I just encrypted my phone, process most probably finished without problems - I stopped watching the phone on around 90%. Then it restarted, boot animation, "enter your password to decrypt the phone", I type it in, green robo shows for 1 second and then black screen (backlighted) :/ After couple hours nothing changes.
If I type wrong password, phone ofc doesn't accept it. Computer sees device, but I can't access it. When I turn off the phone by pressing POWER for long time, it just resets and goes back to asking for passwod again.
Please help me recover my data...
EDIT
before entering password PC says phone is off, after typing it, PC says it doesn't have drivers (it worked normally before encryption).
I can enter fast boot, but IDK what next. Recovery mode just ends with "NO COMMAND"
I see that probably all users who got this problem have Motorola Moto G too. Mostly people who use CM and tried to encrypt phone too.
I downloaded Android SDK, fastboot.exe tool sees my phone in this state. Not sure if it can be used to do something useful....
adb.exe doesn't see device
bump :crying:
So, I left the phone in black screen step over night. Battery ran out. I tried turning it on/off, entering fast boot mode, but nothing happened, then connected to USB. LED turned on for a while, screen too, showing battery with 0%. But now nothing again. Just black or off, not sure. Can't do literally anything, I tried pressing different keys for minutes and changing USB slot.
EDIT
nevermind, fixed battery problem, Moto G with no power needs normal charger or much longer time on USB

Dunno if this can help (and sorry for the grammar but i'm not english and i really suck at it), but for me it's normal to see "no command" on the recovery, to see the recovery commands you just need to:
(Token from Customer Help Motorola):
1. Go in fastboot mode.
2. Select the voice "Recovery".
3. Now the phone'll show motorola's logo and then the android bot with the exclamation mark.
So now, you have to press VOL UP for 10-15 seconds. while pressing it, press and release the POWER button.
U should now see the voices in the recovery.

If you can get the phone to be recognised try reflash firmware

Thanks for replies. Menu in recovery mode lets me wipe all data, so that's last thing I want to do, but I guess I will have too soon :/
About flashing firmware - from what I've read, encrypted data on phone is protected by password and some kind of encryption key/file. Reflhasing would cause permanent lose of that key and thus whole encrypted data.
The only solution I guess is copying that key on PC. Copying encrypted data if possible, and decrypting on PC using some tool, as Android is open source, so it shouldn't be a problem to extract it's decryption mechanism and run it on PC.
OR copying key to PC, reflashing phone, copying back key and praying this time system will start.
Well what's more important I working phone or a few apps??
If you need to get data off the phone maybe using a otg cable and using the file manager in recovery to copy it all over to the USB otg but as far as that I think your gunna have yo count your losses and learn not to encrypt your phone lol....

Same happened to me...couldn't even do a factory reset. I had to get a new phone. I was so mad!!! Now I have a Sony Xperia phone. I just bought it outright so I wouldn't be stuck in a plan.
I've been using HTC U11 Plus as my main phone since the day it came out. I absolutely love this phone. In my opinion it's the best phone I've ever had. I never felt the need to get a new phone. I've been gaming, working, etc. and I never had any issue with it.
Two days ago all of a sudden while using my phone it got stuck. None of the button were working and the screen also had response so I pressed and hold the Power button and Volume Down button to boot into recovery mode. So i could clear cache and reboot again but my phone doesn't seem to reboot. It just turns off when I select reboot now. I even tried "Wipe data/factory reset from the Recovery menu options" and then delete all user data option and then Reboot system now to restart your phone. Still no luck. As soon as I press on reboot system my phone just turns off and doesn't reboot or turn on at all.
Even when I put my phone on charging there is not light to indicate that my phone is charging at all.
PLEASE HELP!!!!
Same problem here... Screen flashed white, phone rebooted to encryption screen to enter pin, then powered off... Hasn't been back on since (thins happened in October 2021).
I'm interested in a possible way to get the data off the phone, even if some parts swapping is involved.
PS. I changed the battery thinking it was that, but the phone still isn't coming on or showing the red battery charging light.
I guess it is time for you both to use ADB. When installed properly you should be able to see your phone in device manager on Windows systems. That in itself would be a good starting point. Or just fire up ADB and check if ADB detects your phone. If you are unfamiliar with ADB, Google it.
In ADB use: *.\adb devices* (without the *) If it works properly you should get a return with a device number. You could then flash a boot image or system image or both and see if your phone start's up again.
Hello,
same Issue here.
Solution is to heat up the Phone above 50°C and hold the temperature while it run and copy Data.
I have spend 40h+ to Backup Data and heat up the Phone.
Seems for me to the same problem like the RROD at Xbox360.
Lead-Free solder at the BGA-Chips.
The problem I have is with the galaxy z flip 3, it worked just fine inthe morning but after it ran outta juice and I charged it to a certain percentage, it stopped working properly, and got into an infinite boot loop, I tried forcing it to restart by long pressing volume down+power , but it didn't work, then I tried opening the recovery by long pressing on volume up+power and yet it also didn't work (I think that maybe it's because it was trying to boot at the time), so have you guys any solutions , please do help me cuz this phone really is important and with all honestly, isn't even mine XD, I'll be waiting for an answer
Your failsafe options are contact Samsung or do a factory reset (and then potentially contact Samsung).
If you can't boot it to anything, the only real option you have is to flash firmware, which likely won't help without wiping.
Unfortunately, not booting doesn't have a whole lot of options that don't wipe data without being rooted. Even then, you'd need recovery.
I see, then I may consider giving it to samsung, as long as they won't reset it, cuz the only reason why the phone is so important is because of the data, altough, isn't there any other way to acess recovery? Cuz I had this problem with the s10 before and I fixed it somehow (a certain Bixby key combination), but this time it seems there isn't any hidden combination.
Samsung is going to reset it. It's a required first step for them to do any work on it, even if the work has nothing to do with the software. What may help find a way to recover the data is starting with how it got to this point. Did you install anything new, change any important settings, or anything else that could have been a part of the issue? If not and it is an unexplained hardware failure, the data is likely gone already.
If it's something you might have installed or changed, it's possible that putting the phone in safe mode and undoing it may solve the issue and let you boot normally.
Booting into Safe Mode:
Make sure the device is powered off (charging is ok, as long as it is not currently trying to boot)
Hold the side key to power on and continue holding until "SAMSUNG" appears and the device vibrates
Immediately release the side key and begin holding volume down until boot completes
If the device has booted into safe mode, you will see a translucent "Safe Mode" in the bottom left

Well I just asked the original owner (my mother), and apparently she doesn't remember downloading anything new into it, and it just went crazy by itself, also something else I wanna note, I tried charging it and it booted into recovery all by itself, I taught it was weird but Still went and wiped the cache and then when I tried restarting it it suddenly ran out of juice once again, also, it's second display shows some weird curruption/bug or glitch-like lines. So based off of this, can you really find the origin of this problem and if there is really any hope of saving it's data XD. Thank you btw, and once again, I'll be waiting for an answer
There are hundreds of reasons it could do that, including a faulty board. Thanks to the removal of physical sdcard support, you'd need to get it to boot into something with at least adb support to pull anything off it. Stock recovery doesn't provide any ways to perform a decent backup, but it sounds like the only option that wouldn't wipe the device didn't work.
I see, alright, thanks a lot, I'll consider resetting it
It may be worth trying to flash firmware first. Go into it knowing it may reset the device or leave you needing to reset it, but it doesn't hurt to try if you run out of safer options.
Same here, same symptoms, happened in front of my wife's and eyes face. We are fairly techy and understand our way around our devices. We also noticed the device crashed then would make it all the way to the home screen launcher and before catching signal the crash would cause a restart at that point I went in and did a cash swipe rebooted right back into recovery by itself then I unplugged the cable and it was acting as if it has a dead battery but when the cable was last plugged in during a couple of crash and then restarts all the way to the home screen I know the battery was at 70 something percent. My next step is going to probably be flashed the current firmware that just released on top of it as a dirty flash and see if I can get it to boot. If not then I'm going to do a hard reset and see if that works. When plugged in it automatically starts exhibiting symptoms as if the buttons are stuck. The devices in the OtterBox and it's fairly brand new I would say mint. Not dirty or any smudges either. all I'm saying is I'm one of those type of technicians that say yeah right when people say it just happened I don't know where but this actually happened I don't know when I was able to witness it. I'll come back and let you guys know what works and what doesn't. (By the way excuse my grammar I was voice typing while driving )

Hello everyone just a quick update. Once I got home I plugged the device into a Samsung fast charger and Samsung OEM USB type-c cable and realize the device booted all the way to the home screen but register the same battery level as I mentioned above. Device was working as if nothing happened to it. So I updated all the apps on the Galaxy store then updated all the apps left over from the Google Play store, I then proceeded to check for a firmware update because I know the April update just released and installed the update with no issues. Updated the apps that needed to be updated again somehow there's always something and unplug the device from the power cable. Everything was working if no issues about half hour later the device cuts off and does not want to power on. FYI I already had my wife contact T-Mobile and get a warranty replacement we only paid $5.00 so my thoughts and conclusion on what's going on something happened to the battery or it's defective. Btw we only use Samsung OEM cables and equipment at home and in the car while connected through Android auto. it's only working while being plugged in it's not charging all the way even though it's registering it's charge level while the device is on.
