Stock on Samsung Logo with Custom Lock Image

I had Mint Jelly2.1 installed and everything was working fine.
it started when I had used the APK Hide It Pro. I was in the process of hiding videos and I noticed that my phone got rebooted and got stock in the Samsung boot up image with the Custom Lock image.
I tried nandroid restore, 2 images, but both also failed to restore / bootup.
I tried re-installing ROM and it was successful but during reboot, it will still get stock on the boot image.
Last step.
I used ODIN to restore the stock ROM and ODIN was able to install and reset. And my phone rebooted but still got stock on the Samsung Logo with CUstom Lock Screen.
What else can I do to fix this?
Thank you.

Boot into recovery and do a factory reset. I assume you now have 3e stock recovery because of ODIN. This might or might not help. If you have any questions about recovery, please use the search function for information. If for some reason you still have a custom recovery (TWRP or CWM), try re-flashing an AT&T ROM and Kernel again. Everything you try is at your own risk. Good luck.

I had tried to restore/flash from recovery before ODIN and it all Failed.
Anyway, the last step ODIN restore and it was still stock at the Samsung Logo with Lock image.
I left the phone to charge the whole night and this morning when I turned it on, it was able to start properly with ODIN stock ROM.
I tried to go to recovery, and can only be done manually, and it was not the TWRP recovery but the stock one, with very small characters.
I tried to install Mint Jell2.1 right away but just reboots.
I realized that I might need to root it again and downloaded the Tool and re-loki'ed/rooted and installed TWRP.
Now, I am able to install Mint Jelly 2.1 and restoring all my apps.
I appreciate the comment.
Thank you.

Yeah, every single time I ODIN back to stock, I get stuck at the splash screen also. And rebooting to 3E (factory) recovery and "restore factory defaults" works great.

I am running out of options. I thought I am already out of this stuck on Samsung Logo with Custom Lock icon.
I had ODIN to stock I337UCUAMDL and reset, Ran Loki patch / installed TWRP, intermittently it will get stuck.
I flashed Shoshock 1.9, was able to reboot and setup basic settings.
I manually reboot to check if it was able to fix the problem, but no.
I am stuck again and don't know what is the next step for trouble shooting it.
any advise will be appreciated.
Thank you.

I got stuck to 1st boot image of Samsung with Lock Custom Icon.
I did format data/factory reset/clear cache/dalvik.. all of the wipe ootions.
I flashed a new ROM, successful, rebooted pass the logo and booted fine. I did not change any settings yet and I rebooted to check if it will get stuck again and sure after reboot, it got stuck again on the 1st image that shows up : Samsung Logo with the Lock Custom Icon.

[Q] Stuck at boot screen after TWRP asking if I want to install SuperSU

I have to think I'm not the first to be in this situation but my searches didn't turn up anything that looked familiar.
I rooted the stock phone and installed TWRP 2.6xx a month or two ago with no issues. Everything's been running great and I decided it was time to make another backup using TWRP.
After a successful backup I wiped dalvik and cache out of habit and went to reboot -- TWRP said I was not rooted and wanted to know if I wanted to install SuperSU? This question was unexpected since I'd been rooted for a long time, and I decided to just say yes. The phone rebooted and stopped at the Samsung Galaxy S4 boot screen. I did up-volume reboot to recovery, but it seemed to hang at the TWRP blue screen -- I later discovered it will eventually get to the menu after a minute or two of the blue screen. I tried wiping cache and dalvik again and rebooting -- every time I try to reboot now it asks if I want to install SuperSU -- whether I say yes or no seems to make no difference -- I've tried both several times. Every time it hangs at the Samsung boot screen, or it takes forever to get to TWRP if I'm booting to recovery.
I've tried wiping cache, dalvik and data with no improvement. I finally tried formatting data, but again no improvement. I also tried restoring my backup several times and wiping cache and dalvik but still stuck.
I prior to today's problems I'd used TWRP a number of times and I don't recall it asking the SuperSU question, so I am thinking that is the key to this problem, and I'm wondering if anyone knows what it means?

You need to go to 2502 twrp, 26+ has hanging problems and possible Partition issues, also what rom are you on? Do you need to flash super su along with the rom /gapps?
Here's the twrp forum for us SPH-L720
The last page has a download link for the most stable build for us good luck!

I'm running what came on the phone, just unlocked, rooted, and installed TWRP.
I ran CM10.1 on my previous phone and currently on my tablet, but my impression from running it previously is CM is a downgrade in voicemail functionality (you get these annoying text messages and have to call the voicemail), and I'm assuming it doesn't support the special GS4 hardware features like being able to hover your finger.

OK I installed TWRP 2502 and it now boots to recovery normally. However, it still asks me before rebooting if I want to install SuperSU, and it hangs on the Samsung boot screen.

How did you root? CF auto root also installs SuperSU
Do you have a back up from when you were rooted? IF twrp keeps giving you problems, use cwm, are you able to get past the Samsung boot..

Yeah that's what I did back when I rooted it months ago. I tried running CF auto root again today and it didn't work, so I ran it from Odin and it did work that time, but there was no change -- still hangs on the Samsung boot screen, although now I'm back to the stock recovery. So I tried installing the stock MF9 firmware from Odin -- still hangs on the boot screen. I don't know what to do at this point...

After mf9 install avd stock recovery did you factory reset

Yes, I did a factory reset -- followed the video instructions by qbking77. Still hangs on the boot screen.

Take out battery.. Put back in. Go to stock recovery, holding all 3 buttons volume up factory reset.. If you used odin abd flashed mf9 it should fix you?

Im also stucked with the same problem!! After flashing my rom succesfully it just ask ur device is not rooted swipe to install!! I tried all the posiblities!! but i stuck with the boot image!! pls help me!!

From experience it sounds like you should head over to sammobile and Odin back to stock and start fresh.
1. Odin to stock
2. Root phone
3. Put desired recovery
4. Flash ROM (be sure to read dev install instructions some require reboot of recovery after wipe)
5.try to restore backup (best if you flash ROM that is backup then restore backup)
6.if you went into nae or ng2 you cannot downgrade to me
7.google has many solutions
Sent from my SCH-I545 using XDA Free mobile app

Sorry for necro, but did anyone figure out a solution to this? This just happened to me.

Just Reflash it
We have the same issue, tried to install supersu binary, after installing through twrp recover, my phone went bootloop, as i've tried to search the internet, the issue doesn't fix by by most of the users unless they reflash their device. though its a bit hassle starting from zero, but atleast, you got ur device back

This helps me:
1. Run Odin on your computer and, after entering download mode on your phone, establish a connection between your devices with the help of the USB cable.
2.Note: for download mode – power off your smartphone and then press and hold, at the same time, the Power, Volume Down and Home buttons.
3.Odin will try to recognize your device; if everything works as expected, on the program the “added” message will be displayed and the ID:COM field will be turned yellow, or blue. (Note: if that’s not happening, unplug the USB connection, close Odin, force restart your phone and reinstall the USB drivers on your computer before retrying the steps from above)
4.From the program click on the “PA” button and load the custom recovery image; don’t check Re Partition and Auto Reboot options.
5.When done, click on “start” and wait while TWRP recovery is being added on your phone
6.In the end, Odin will display the “pass” message and the ID:COM filed will be turned green (or other color) with message - RESTART; you can then remove the USB cord and reboot your smartphone.

I have had this prob on a few things , if you have a backup,flash any mod that will go to the device will do then run the backup and reflash should work .and if you have twrp try to reformat all but the system and see if that helps.
Good luck.

Hi to everyone.
Today, I installed the TWRP and the ROM and both were installed correctly on a Le Pro3 X722. The problem started when the Google services were updating. Suddenly, the phone restarted and entered in a bootloop. I was not even able to enter the TWRP. The page freeze on LE-Recovery logo and then crashed (fill full of lines). I disconnected the battery for a while and then, I was able to enter the TWRP for 2 time but recovery crashes in few seconds. I wanted to wipe and install a clean rom but I cannot enter TWRP anymore.
Please, Is there someone that could help me?
Thank you very much in advance
PS. My phone is not recognized via ADB. I tried with the AIO Tool but my device is not detected.

Hi, I followed the whole process for Qfil explained here:

Installation was correct but nothing change in my phone:
- same start page and bootloop
- Same problem trying to access the recovery.
Now, i can connect via fastboot and I would like to install a fastboot rom (preferable EUI stock 20) but I cannot find one. All links are dead.

Cant get out of TWRP

So i just did the new update on my V20 and it sent me straight to TWRP and i cant get out of it. It always boots into TWRP. What can i do? ive already tried a factory reset and restoring my back up and nada. Help please.

Its now looking for stock boot image which on yours is currently modified with system rooted.
Try using lgbridge to repairs your boot image or if you have it flash the stock boot image using fast boot command or do a factory reset while in twrp then flash entire stock image with lgbridge.

Yeah none of those work. The OS is setting off some sort of flag that states it must go into recovery and wont stop going into recovery until that flag is changed which I assume is done by the update. I tried updating with UPPERCUT/LGUP and it errors out at 4%. So right now it's still stuck

It didnt install the update
type
Code:
fastboot erase fota
from bootloader and see if it boots after that.

This will for sure fix you up...
https://forum.xda-developers.com/v20/how-to/how-fixed-bricked-lg-v20-t3501310

listen to me2151
delete fota and then pull battery and reboot.
ota's downloaded to the fota folder will cause endless twrp loop.
freeze ota in system/privapps to avoid this again.

Sorry to post on here, but maybe we can get a few tips from each other.
Im also stuck at TWRP. I installed a ROM and went back and forth between both ROMS. After about 4 times of going back and forth between ROMS, my pattern didn't recognize on boot with my original backup and daily. I tried my pattern over 10 times and it wiped everything on me. The strange part was I was swiping my pattern 100% and it failed. Also, my tries were going up and down. It would say I have 6 tries left before my phone wipes, then I would stop anjd turn the screen off, and the screen would say I have 3 tries left, then 5 tries left. My tries were inconsistent, and it finally wiped everything.
I am now stuck on TWRP with no luck of restoring. I flashed the vs995 boot image and system image and it goes back to TWRP. I factory reset, wiped everything, made sure the system folder was clean, then flashed both images again and the same thing, no luck.
I also tried to restore with LGUP, but keeps stopping at 9%. I extracted the dll and copied it into the common folder and I get the same thing.
Error: Error Code = 0x2000, Flashing Fail
When I plug the phone into my computer it shows us996 and not vs995. Strange.
Any help would be amazing.
EDIT: Figured it out!
So, I extracted the dll file from the kdz file and I had to replace it with the one in the common folder. My error was not renaming the file, so the LGUP would stop at 9%. Make sure you pull the file, rename it, remove the old file from the folder, and flash on LGUP.

Need Help; My LG G6 (H870) keeps booting in TWRP and I can't install stock ROM

Hi,
I unlocked the bootloader of my H870, installed TWRP 3.1.1.0 and SUPERSU. Everything was working great untill I decided to restore my system defaults to make a fresh start with my G6. After choosing the option to restore system defaults, my phone rebooted and it booted into TWRP. I rebooted my phone and it kept doing this all the time.
I decided to look for a stock ROM and flash that ROM.
I succesfully flashed the "LG-H87010f-Flashable.COMPLETE.zip" ROM (from autoprime's post) trough TWRP. But this did not work. I even wiped all the data from my phone (even system) and flashed the ROM again; still nothing.
Before having this issue, I had the same Baseband version, Kernel version, Build number. Only the dates and the Software Version are different.
I had the V10b-EUR-XX Software Version installed on my phone. I see this is the 10f version. I guess this should not be a problem right?
After this I took these steps solve this issue:
1. Downloaded new LG Mobile Drivers (LGMobileDriver_WHQL_Ver_4.2.0)
2. Downloaded and installed LGUP. LGUP doesnt recognize my phone as a LG G6 and this method did not work for that reason.
Fastboot mode is working on my phone; I can reboot my phone trough the commandline on my PC and things like that . However, my PC is not recognizing my phone as a LG G6 device in Fastboot mode.
My PC recognices my phone as a H870 when in TWRP. In Fastboot mode it recognices my phone as Android Device.
3. Installed LG Bridge for more drivers; did not work either
4. Downloaded Uppercut, but it doenst work without LGUP.
4. Looked all over the internet to find a Stock ROM in .zip or .img format; found nothing
5. Downloaded WindowsLGFirmwareExtract-1.2.6.1 and tried to extract the H87010d_00_OPEN_EU_OP_0327.kdz file. I extracted it into .bin files, but they were not usable. After that, I combined these .bin files into a system.img file. But that .img file was bigger then 5 GB and for that reason it was not usable to flash trough Fastboot or TWRP.
7. Looked for other methods to obtain a H870 Stock Rom, including another extraction method, but I cant figure out how to do this.
I have spend countless hours on this problem, but I cant find an usable H870 stock rom to flash my phone with.
Is there someone that can help me out with this problem? Im willing to donate some € if someone helps me to get my phone working again.
Really hoping for a kind person to help me out and provide me solution for this issue.
Thanks in advance

Try formating data in TWRP(not factory reset) then flash the 10f complete zip. Trying to perform a factory reset from within Android could have possibly messed up your data (due to TWRP being installed instead of stock recovery) so a full data format is needed.
Lgup most likely doesn't detect the phone because you wiped system. But flashing the complete zip should have restored system.
In the future make backups in TWRP to restore later.. or flash a kdz with lg bridge or lgup without wiping system first.

Thanks for your reply. I have already formatted data in TWRP, but im still having this problem . It seems like something is preventing my device from starting up. I have flashed several ROMS on other devices, but never experienced something like this. Is there something else I can try? Can I flash the stock recovery and flash the stock ROM? I got the feeling TWRP is causing this issue.
If its possible to flash stock recovery, where can I find it?

Flash the complete zip then boot into download mode and flash kdz. Lgup should see the device as a g6 now instead of unknown device. If lgup isn't seeing any device at all (including unknown device) then your setup is off.. missing drivers or something. If that doesn't work.. idk.

Don't factory reset using the in phone option. You can only do this through twrp's option. To fix this you'll need to boot through the hard side, using power and volume down until the lg logo appears then release power for 1 sec and then repress keeping volume down pressed. Confirm yes twice on the white screens to get to twrp. Once in twrp then reset again and reflash the system. Then using twrps img installer flash your twrp img(make sure it is on ext sd) again. Then reboot.

Probably because you already did all the flashing prior to. Glad it worked. This happened when I first got my V20 and was stoned not thinking. I reset using the in phone option and it caused twrp bootloop. I too learned the hard way.

Had the same issue, fixed it, thanks.

Great tip @Swizzle82! It allowed me to restore my LG G6 after bootloop. It had not been detected by PC, and this hardware reset helped!

Hi, all
If I understand, and to sum up :
I rooted my LG-G6 few weeks ago, and intall TWRP. When OTA wants to install official update, the reboot stops in TWRP mod, so ... failed :-/
Is the solution to flash through Uppercut/LGUP with a .kdz file, without risk of brick the phone ?
Thx

Bricked H819 while trying to go back to stock

Hi,
i used LOS but the phone broke and i had to revert back to a stock image in order to get it fixed.
I restored laf/download-mode and flashed a kdz using LGUP with the appropriate dll. After the flash finishes, the phone reboots, but never finishes rebooting. I have to remove the battery to get it off again.
Is there anything i can try?
Thanks.

So you're stuck on the bootanimation? Did you wipe before restore?

The boot looks as follows:
LG logo
Unlocked boot loader message
LG logo
A colourful circle with "Erasing" written underneath
The Phone seems to turn off and on again
LG logo
Unlocked boot loader Message.
LG logo
White T-Mobile-Screen
"Android is starting", "Don’t turn off your phone". With a loading bar reachting 100%
Repeat from step 9.

I used LGUP to flash a kdz. I don’t think wiping is an option there.

You could wipe before flashing, or use the Refurbished option in LGUP (doesn't work for all KDZs). Pull the battery, use the recovery key combo to wipe, and see if it boots.

You mean a twrp wipe? Because i don’t have twrp anymore. I only had it on laf, which i reflashed to download-mode.

I might want to try that.

Again, are you assuming i have twrp on the recovery partition or are you talking about the stock recovery?

I mean like you could have wiped with TWRP before reflashing the KDZ. You can also wipe using the stock recovery

I did that just now but the boot behaviour looks the same.

There's another user on the v20 subreddit with similar problem to your as well (flashed KDZ from Lineage, bootloop), phone had issues before. Could be an issue with Lineage, could be the hardware issue causing it to not boot. If you're returning it to get fixed, I don't think the bootloop would be a problem, just tell the warranty guy it started bootlooping as well. Without logcat (and you can't get access to it without root), there's no diagnosing why its rebooting.
I haven't had the exact same problem, but I've experienced something similar. If the /persdata partition gets corrupted, US996 and US996-based ROM would no longer boot, because it writes log to the partition as part of the first boot process. F800 (korean) doesn't care about it because their ROM's partition table doesn't have that partition at all, while LS997 and VS995 have but don't write to it. Unfortunately, you can't crossflash to other device's KDZ due to the H918 having a different RSA key (and probably incremented ARB if you used lafsploit), so there's no diagnosing the exact problem, but I suspect LineageOS might have damaged a partition or something

There is still the Refurbished option in LGUP, which i haven’t tried yet. After this fails i either return it as is or get a new mainboard.
Thanks for all your help.
In the meantime, maybe someone else has a suggestion.
