Hey all, been a while since I've been on - longest I've ever had a stock phone for . Hoping somebody can offer some advice as I'm stumped...
NOTE: If possible, I'm trying to avoid a factory reset!
Last night my stock UK Note 4 (SM-N910F) died (possibly during an OTA update but I wasn't using the phone and have been told it didn't so not sure) and when turned back on would just sit at the pulsing Samsung logo with no apparent restarting or anything. Clearing the cache didn't make a difference.
Recovery reported my ROM to be N910FXXS1DQE9 (region BTU). After waiting ages for the download, I first tried BTU-N910FXXU1BOC5 which produced the exact same problem with a different Samsung animation. I then tried BTU-N910FXXU1DQHC which seemed to sort of work - it would now boot but gave me a "Unfortunately, System UI has stopped" error with a black screen. I then flashed BTU-N910FXXU1DQH3 which is what I have running currently but this does the same thing. I did also try wiping cache in combination with the above (is this actually needed after flashing a new ROM?). I have also tried safemode - would let me open the power menu but otherwise did exactly the same thing.
I'm currently downloading the original ROM that wouldn't boot (N910FXXS1DQE9) from samsung-firmware but it's taking ages at ~50KBps. What are the chances of this working compared with the others, I assume probably not much? If likely, I'll pay up for an account and a quick download.
I've also tried flashing TWRP but I have reactivation lock on - does anybody know a way to disable / bypass this without access to the phone (research tells me probably not but there are a lot of smarter people than me here that I hope could tell me otherwise ). I can get into stock recovery but that only gives me ADB in sideload mode and I can also enter download mode fine obviously. Does anyone have any suggestions on recovering data from the phone before I factory reset?
Simply put, have I lost everything on the phone or is there a way I can retrieve some of it?
Also, I do have a load of server space I can offer with decent bandwidth - I have those ROM images above so I can offer these for download at a decent speed without a cost if anybody here on XDA needs - just send me a PM for a link

Hello I have messed up my Sprint S4 quite a bit I am posting in case anybody would be nice enough to shoot me some pointers. I hope I following the guidelines here.
Things I did that screwed up my L720 :
First I installed the hotspot mod via filesystem on the phone. ( this didn't seem to harm anything though but worth mentioning )
Second I took it upon myself to delete some system apps ( this is what seemed to messed me up)
Third I factory reset the phone ( now all is hell)
Notes:
The reason I factory reset the phone is that when I would try to install a new app from the play store that would not work.
Now when the phone boots it optimizes 122 apps then goes on to give me an alert box I believe for each one saying it is busted overlaying the samsung account wizard thing. And it doesn't let me past the boxes.
I never enabled USB Debugging
Attempted Solutions:
I tried to re-root it with the CF Auto Root thread using ODIN but that doesn't seem to help.
Then I wanted to download that Samsung-Updates.com-SPH-L720-SPR-L720VPUAMDC-1365579188.zip file from that thread and follow that tutorial but hotfile lost connection and is now having me wait 30 minutes before I can attempt to download it again.
I figured during this time I would post my problem seeing if anybody had a quick fix. That I am not thinking of, possibly some kind of recovery deal. Not that I have ever backed anything up.
Thank you for any suggestions
Pull the power plug on your router for thirty seconds then plug it back in again. That will give you another ip address. Restart browser and make sure you clean all history and cache and cookies. Now go back to download mdc again or try a mirror. Flash in Odin then reboot back into stock recovery and do a full factory reset wipe. That should put you back to stock. Next time, don't be as careless removing things or you'll be in another mess.
Thanks for the response, I was not able to get back to stock but I flashed cynogen rom so now my phone is functioning. Now I am going to see if I can follow the tutorial of getting stock rom back on.
Well this is my 1st post so first of all hey everyone
I just spent a week in Amsterdam and my phone restarted twice, different times different days and I dont remember what I was doing with it back then.
But as I landed back home I put the phone back from "Airplane Mode" and went on to toggle "Cellular Data" on.
The second I pressed the cellular data shortcut on my the phone restarted itself but this time whenever it would finish the screen would be on but fully black and sometimes it'll show battery precentage at the top but then will restart again in an infinite loop.
Sometimes it'll pop up the "Optimizing Apps" window and will go through all 24, upon finishing it will restart once more and do the same.
I tried using the bootloader and it worked (the bootloader that is) but the phone would do the same thing even after Rebooting from there or shutting down from there and then turning back on.
I contacted tech support on chat but they couldnt help past telling me to go to bootloader and reboot, said I should factory wipe when it failed.
Also tried wiping cache but to no avail.
I have no backup of my phone (wanted to do one before the flight but got lazy and I suck for not doing one sooner) since probably October and google doesnt backup my contacts properly for some unknown reason.
I already downloaded Android Studio with everything included for me to try using adb to sideload stock without wiping but its my first time and I couldnt get it to do anything at all...
I already got the official stock .gz file from the motorola website.
Anyway here are the specs to my phone:
XT1575
Everything is stock. didn't root or change recovery once in my life.
Was fully updated and had plenty of drive space (I have almost 128GB with the 64GB version + 64GB SD)
I'm really lost here so help will be very appreciated.
Thanks in advance,
-Noam
Start with a full wipe and if that doesn't work flash the stock image. Not sure what your question is though as you never really say. Once fixed I would unlock and make a backup so you don't have to deal with this again.

The thing I pretty much want to know is if theres a way to either backup the phone now with it connected to the computer while in bootloader or recovery. or a way to flash the stock rom without wiping which I read someone did with his tablet. I cant post source normally because I'm a new user so here it is but change spaces to dots: schnouki net/posts/2014/08/13/flashing-a-stock-android-image-without-wiping-user-data/
Also while in recovery I noticed 2 options under wipe: 1. userdata only. 2. userdata+(insert something I dont remember here) and I was wondering what gets deleted in both? if I delete only userdata what data will remain? something helpful?
Sure you can try flashing without wiping data but being locked I personally wouldn't risk it. No idea about backing up in your state... somewhere I remember a thread on backing up without root try searching in q&a.

Out of curiosity why shouldnt I try flashing with no wipe if ill lose the data anyway? worst case wont I just have to wipe after it fails and flash again?
And I will try thank you
Do you have any knowledge about the 2 wipe options?
Thanks in advance
Well I tried turning the phone on and it took a couple of minutes before loading to a fresh start. It apparently wiped itself on its own. Managed to restore almost everything.
Anyhow the phone takes too long to boot now. Was even stuck at boot and I had to restart it.
Anyway to fix my software? Or at least check for corruption?

So i was simply updating youtube through google play, and messenger through messenger it self and suddenly the phone went into boot loop and can't get it out.
opening recovery mode is hard but when i managed to do it, it simply shows the android icon and installing system updates then restarts again. (tried it ~4 times). thanks to that i can't try clearing cache or any of that stuff on the list that is supposed to appear in recover mode.
trying force restart also does nothing.
trying to remove memory card and sim also didn't work.
i read that flashing HOME_CSC from a rom could fix it but the rom websites i know offer limited sizes and speeds and i don't have a strong internet which ends up timing out, can someone help me out? G935FOJV2ERGE is the one i need.
if you have any other ideas that can help, i would also greatly appreciate it, i really don't want to have to buy a new phone atm, and don't want to lose all my data because i don't used backup services cuz they ate up data .
edit: I am on latest official rom, only used OTA updates, haven't rooted the phone.
edit 2: i managed to get a different region's rom and flashed it's home_csc file, and force restarted it and seems to have worked booted, then it started doing it again just 1 second after that. i didn't even have time to unlock it.
edit 3: managed to get into recovery mode list once, wiping cache didn't work. couldn't get into recovery mode again after that. then i gave up and tried flashing a full rom. still the same problem.
I i had to reflash the firmware the correct one TB-X104F_S000024_180930_ROW_DCC. Anyway it wasn't booting at all before i flashed. Now it boots, shows the logo etc and constantly says Encryption unsuccessful!, so i reset it and factory reset it but nothing changes.
I have no idea where else to go, bootloader is locked and all i can do is flash the firmware. Would there be a way to remove this from the files within the firmware?. It seems like android is there in the background but i can't get away from that encryption unsuccessful screen!
Sorry if none of this makes sense.
Yo. I got the same tablet bro. Been trying to figure out a custom recovery for her. A stock ROM would be great to have and I haven't been able to find one anywhere. Might I inquire as to where you found yours? It would be a huge relief to know I can fix it if I break it lol.

If you download the Lenovo MOTO smart assistant from Lenovo support it has a resque option. I also used that to root my tb-x104f. It downloads the original everything and if you take the boot image from the file it downloads and replace it in one that has been modified from magisk it will rescue it and you will have root also thatd what I did with mine
same problem here, reflashed with stock rom. and not resloved

Did you fix this issue?
I am having the same problem.
Thanks
Same problem here (my error reads "Decryption unsuccesful", but I think it's the same as yours).
After a few tries, I believe that it is a problem with the internet connection. After the factory reset, if I skip the wifi connection step, it starts normally. And it is completely usable. I can load pdf documents or apks by the usb from a computer and it runs correctly. But whenever I try to set the wifi connection, it updates something and it causes the tablet that the next time I turn it off, I find the error on the picture when turning on. It asks for a password and no matter which password you enter, then it delivers this message.
In resume, right now it is a completely functional tablet if you NEVER connect it to the internet and load anything you need via usb or bluetooth.
I tried to reset it with Lenovo Smart Assistant, but the result is the same.
I am looking for custom roms to try if it's something about the stock rom, but I haven't found any. Can anyone reccomend me a rom for Lenovo E10 X104F 2GB?
Solution: (Worked for me)
Format Data as F2FS in TWRP. (Advanced Wipe)
Then reboot and wait.
OKay long story if you're interested in details, this is different to the other bootloop issues, I think this is HW related.
1- Phone suddenly started getting into booting loops. Phone never rooted nor flashed with customer ROMS..
2- Strangely this happened after an official update from Samsung.
3- Booting in recovery mode, wiping cashe and rebooting helped and the phone worked but only for a month or so until it started getting into the loop again.
4- This time it's more stubborn, it doesn't even allow me into recovery mode, it reboots before I can do anything.
5- once every 50+ times it would allow me into recovery mode, I tried wiping cache and factory reset but they didn't help, phone always restart after the samsung logo appears.
6- I thought this is the time I try flashing a custom ROM and see since it was on Stock ROM, but unfortunately realized I had OEM disabled and hence FAP ON and can't flash custom ROMS (or can I?).
7- I thought to flash stock ROM again using Odin. I did so, nothing different, still getting the same issue and now even worse, it would sometimes just give a black screen with flashing blue light.
8- something weird regarding the Stock ROM, my devise is G-SM935FD, however, the latest official update samsung installed on my device changed it to G-SM395F, I know they are mostly the same but trying to use the latest ROM from Sammobile for SM935FD wouldn't work. only the one for SM935F is accepted by download mode. Probably it's because I bought the phone from Dubai (395FD) but then moved to Portugal, so it started sending me the updates related to Europe.
Now at the moment, the phone can't load beyond the samsung logo. It can occasionally get into recovery mode. The only stable mode is download mode but I can't flash any customer rom or twrp because of FAP ON.. so I can only flash stock ROMs which didn't change anything. Does anyone know a way out of that? maybe a ROM that can bypass the FAP ON and uses less processing to load. I know I'm probably asking for something magical and I would most probably not get any answers over here.
I have no warranty and the phone is in a horrible condition so I am not sure if taking it to Samsung would be useful at all.
