Help! My LG k20 plus is boot looping, I don't know how to fix it - LG K20 Plus Questions & Answers

My tmobile LG k20 plus phone has a boot loop and will not start, this happened when I copied a file to the main directory of my phone, instead of merging the files it deleted the system folder, I tried to fix it by reinstalling twrp and it worked, after flashed twrp I installed a fresh SuperSU ROM and when I did the boot loop did not go away and in addition to this my computer will no longer find my phone through ADB or fastboot, if you can help I will be amazed and quite happy, I'm new here so any help is appreciated

did u ever get it figured out? i am in the same boat grr

I found a program called lgup which was able to fix the phone, it's capable of flashing a new rom onto a soft bricked phone. Sadly I don't recall any specifics but on a quick search for "lgup lg k20 plus" you should be able to find what you're looking for with relative ease. Also, you may want to consider making your own thread on the future... It has been 3 years

Yeah. Sorry for the late reply given you guys found the fix by now, but yes, generally with the sort of severe mishaps from editing or accidental deletion of certain system files or directories, sometimes a dirty flash or even a totally clean flash after performing data ave system partition wipes, will just not fix or restore the device.
You would then need to do a complete stock image reflash either using LGUP or the official LG software recovery tool. If you know what you're doing, you could skip over reflashing stock in its entirety, if say you know the problem has only to do with a particular protected partition like modem, EFS, etc. But generally good practice to just recover all the stock partitions, refresh the device software to factory conditions, reflash your bootloader and recovery images, root STOCK or install custom ROM, so on and so forth.
If you're a frequently curious tinkerer, making backups will be crucial to your sanity.

I need your Galaxy On5 (USA) ROM

Hi, I need the ROM for this phone, more specifically, the boot.img file, as the current kernel is for the older, Indian revision of the On5, and my revision, the USA version SM-G550T1, seems not to have any copies of its firmware floating around. I'm running an OS for the SM-G550FY, which has no audio or camera support. Even if the version isn't an exact match, if you bought this phone in the USA, new, in 2016, your boot.img will probably work. I need this kernel guys. Please, if someone has an On5 in the USA, can I please get a copy of your boot.img and possibly system.img? I really care about the boot.img.
Thanks guys

Firstly, did you try the updated ones at these locations:
http://www.theandroidsoul.com/galaxy-on5-stock-firmware-2-86761/
http://firmwarefile.com/samsung-sm-g550fy
Secondly, why exactly do you need the boot.img, what problem do you think it'll solve? Is there any specific issue with your current ROM that you are trying to solve?
Yes, I did, but as you can see, those are for the SM-G550FY, not my SM-G550T1, and the camera and sound (including phone calls) don't work!
This makes me strongly suspect a driver issue, which could most likely be fixed by getting my hands on a copy of the factory boot.img.
Running Android 6.0.1 right now, compiled for the SM-G550FY, but I can't get it working.

>> and the camera and sound (including phone calls) don't work!
Did they not work from day one or did they just stopped working after a passage of time or due to rooting or an OTA upgrade? If you didn't root or install a custom ROM, there is just no room for a software/driver issue to happen. Did you try wiping the cache partition and doing a factory reset?
EDIT
In any case, boot partition is the last place you look for actual component issues like camera or sounds. All the boot partition does is just kickstart your android OS and then the control is passed on to the system (as soon as the logo animation starts).

There you are! I just cannot emphasize enough that why don't you guys backup your existing ROMs before flashing a new one? It hardly takes five minutes with CWM/TWRP recovery.
In any case, what happens when you flash the Indian ROM (5.1.1)? I guess that could be your only option.
Otherwise, you can put a request on the CyanogenMod thread for your particular Samsung model.
For future reference, perform device backups and all the research before flashing a custom ROM, not after the fact.
EDIT
If you can contact Samsung support, see if you can manage to get a stock ROM from them that you can flash using ODIN or something.
I contacted them already, they basically told me to go **** myself. The missing ROM is a result of bad parameters I accidentally put in to Heimdall/ODIN flasher. I wanted to back up, but ironically, my first attempt at installing TWRP is what destroyed my ROM.
I've downloaded the kernel source code from Samsung and I'll try compiling it myself. If I create a working boot.img, I'll post it here.

boot.img is where the kernel is stored. I know, I decompressed it.

You are right, boot.img has the monolithic kernel, however, a lot of drivers are available as separate modules in /system/lib/modules/, so you need to make sure that one is proper too.
In case of Samsung, I think it was probably a mistake to use TWRP/CWM to backup or flash ROMs since they don't tend to work as well with Samsung devices as ODIN/heimdall.
Yes, do post the result of your output once you are done, so its helpful to others.

The kernel on this device does not have loadable module support. It's entirely monolithic. And, I'm having one hell of a time building a kernel this thing is willing to boot.
I really would love just to get a ROM from someone else's SM-G550T or SM-G550T1.
locked out by frp so i cant even turn on my sm-g550t1 so if you find the rom please let me know

I found a copy of the MetroPCS version: https://drive.google.com/file/d/0B_VtvT1vGmlsMjNnR2JvYzk0MFU/view?usp=sharing
You flash this with TWRP recovery, because those are tarballs and can't be flashed with Odin etc.
You flash TWRP for the On5 onto your recovery partition, and then restore from that.

thank you!
however, i can't install twrp to my recovery partition anymore because i got FRP locked, and i can't go into my settings to disable it now. so i think my only option really is via odin. i'll see what i can do with this though, thank you very much. i did have twrp on there before but after i got frp locked i can't go into recovery mode at all.
I've been losing my mind trying to make this work.
I think if I installed the stock recovery.img it may work, but I can't find it in the files you sent. Would you or anyone else be able to make a copy of it for me? I would be eternally indebted to whoever could.
If you want to go back to stock then use the official samsung software. I got a s6 tht a friend of mine straight up deleted the rom (idk how they managed that) and it wouldnt take to being flashed in odin. I put it in download mode and provided samsung smart something with all the info it wanted and it installed the stock rom and everything.

unfortunately smart switch is incompatible with this model phone for the time being.
I got four of these from T-Mobile when we switched from Verizon ($120 for 4 lines). Three of our Verizon phones worked well on T-Mobile (after a few APN tweaks), but my dad's old Galaxy S3 barely worked at all, and when it did, only got Edge for data. So I set one of the On5 phones up for him.
Everything was going great. I put the TWRP recovery on it, rooted it, froze all the bloatware, and backed up/restored his apps from the old S3. However, he wanted me to see if I could restore all his SMS/MMS. I tried restoring that, and the stock Messaging app started FC'ing. I installed Textra, which worked (and saw the old messages), but he never received new texts (even though he could send). So I tried removing Messaging and Textra, as well as the SMS cache (which seemed to be in "Dialer Storage (Phone SMS/MMS). I removed it, but now I'm getting an error every five seconds about "com.android.phone" and can't seem to get rid of it. I tried to restore the dialer storage backup again, but it just seems to sit forever without installing.
I've looked far and wide for a stock ROM... hoping I could just put this mess behind me, but I'm surprised to find it is nowhere to be found.
My other alternative would be to fix the com.android.phone error, but nothing seems to fix it.
Which cynogenmod or any custom os suits for Samsung Galaxy on 5.......please tell me guys.....I am bored with this official os
I was really hoping to come back to this forum and finally see stock ODIN files for this phone. I really, really want to get rid of the MetroPCS ROM I used to fix it.
Has anyone been able to find it?

How do I fix a bootloop?

The phone is a Moto g7, Verizon river xt1962-1, rooted with Magisk and TWRP.
I wanted to update to Magisk 19.4, so I made a TWRP backup and ran the unroot patch and went back to 19.3, but I still had the problem, so I decided to restore from the backup. After the backup, I am stuck in a bootloop, the whole "Your device is unlocked and cannot be trusted" screen over and over. I can get into TWRP, but no backup that I have tried will fix the boot loop. I tried a few things that just seemed obvious to me, clearing the cache and whatnot, but I am still stuck. I have adb and fastboot at the ready, but I don't know where to go from here.
I do not even know what build I am running, I cannot get into System / About to see, and I am not savvy enough to know any other way to find out. I know that it was current stock, missing only the most recent patches.
Is there a way that I can restore my phone? I would be grateful for any help. Damn, I love this g7 so much more than the Note phones that I had been using for years, but I was at least a little familiar with them. Thanks for any help.
Sounds like you'll need to fastboot flash a stock rom to your phone, use TWRP to get into the bootloader/fastboot mode, and also sounds like you messed up the boot.img when you were trying to go through that process. I just updated the Magisk app from within the app itself - no issues there. Might be a good time to update to a newer stock rom as well, might as well take advantage of the situation amirite?
But just for different options, here may be some useful links

Try to flash the stock boot.img and you'll be fine. If you haven't got a stock boot.img you will find a backup of it in your /data partition (magisk does a backup of it by default). Just unpack the TWRP backup of your /data or download the latest firmware to get a boot.img

Mate, I can't thank you enough, now I am back up.
I took advantage of the oppotunity to do a Titanium backup and flash the latest firmware, since I was still running old security updates.
I am not sure why the TWRP backups caused a bootloop, that concerns me. I am diligent about making one before any significant change, and now I see that none of them were good. It might be that the backup I applied included boot, and somehow that caused an issue.
In any case though, thanks a million. I would PM you a beer, but they tend to go flat when they hit the first ATM gateway. Hops and TCP encapsulation don't seem to be compatible, especially at > 9600 baud ?

Thanks man, I really appreciate it! I did take advantage of the opportunity to update, something that had been bugging me for a while anyway.
I had updated Magisk to the beta through Manager, but a problem came up and I needed to step back to the stable version. That was where I messed up.
In a way though, it was just as well, since it forced me to spend a little time reading about the G7 ecosystem, something I really hadn't done much of yet. It used to be fun keeping up and flashing nightlies, etc, but over the past few years, it has got away from me. If it wasn't for a few specific things, I would almost stay stock. But I get uncomfortable thinking about the ridiculous amount of personal information a stock phone releases about us, so things like Signal and xPrivacylua are important to my sense of well being. Even if some of it is placebo.

I'm glad to hear that! Don't worry about the beer!
I had similar issues with my Moto g6+... Either the /data encryption or Magisk is the reason for a failed backup. Both can cause a bootloop. But it's always good to have a stock boot.img.
I'm reading this because of the same issue in a Moto G7 Power. I haven't been able to make it restore a backup at all of either stock or custom. Oh, it will restore it just won't boot. I think it has something to do with the A&B system slots. We use a TWRP that was made for system with A&B slots but then we flash a copy partition zip That I'm not sure what it does. Maybe I should take it apart and have a look. . Has anyone been able to restore a backup in the G7?

Do a full restore of boot, system and data.
Is data...
...encrypted => Then format data (not wipe!!) and reboot into system. When you see the "Welcome Screen" turn off your device and boot into TWRP again. Restore data and it should be fine.
...unencrypted => Then format data and restore data (w/o reboot!!)

How I fixed my Realme x2 Pro from not booting into system

So earlier I spent hours trying to fix this with no luck. I downloaded probably over 12 different roms, same thing. I've posted on the questions forum for help and we still couldn't figure it out.
It would go right back to recovery, so I was curious and flashed AOSIP custom rom and it booted right up!
From there I downloaded the stock recovery.img, flashed that. went to wipe, tried wiping regular, didnt work. So I clicked format data, it finished then installed the stock rom and everything is working.
This may not work for everyone, nor am I saying its a guaranteed fix, it's something that worked for me.
Let me know if this works for you if you want the stock recovery img, I can upload it too!
Huge shoutout to @Sergiocubano1 who spent hours trying to help me fix the issue. Happy flashing everyone, also if you go back to a custom recovery orangefox/twrp I would suggest creating a backup of your rom and putting the backup on your computer.
I wonder why it is not possible to restore this phone by putting it in EDL DOWNLOAD mode.
I would like to return stock with the RMX1931EX_11_A.08, because now with this system I suffer from random restarts but I am stopped for fear of brick.
On youtube there are guides for unbrick, but there are passwords to the software for flashing in EDL DOWNLOAD that they release for a fee of $ 20.
I honestly didn't believe this phone was so limited on a mod level.
Such a pity.

I wouldn't trust them. Did you try this method?
I don't trust them either. For this reason I have not tried.
however other devices like oneplus have the possibility.
to perform a total reset of the device through this EDL DOWNLOAD method.
in this device it is all very strange.
this device has very interesting specifications but is very limited.
I am looking for a system to do a total reset of the device with a stock version.

@xHvlios Please how did you get the stock rom ozip into the stock recovery? I tried putting it in the device storage but when I go into stock recovery -> choose language -> install from storage device -> From phone storage; nothing happens. I also tried putting it in a flash drive but I can't see this device in the recovery.

Phone won't boot after TWRP restore

I really need help. I don't have a usable phone.
It's a long sad story but I had a working rooted phone with stock Android 9 and Magisk. Because I could not get OTA updates I wanted to update the old version installed, but never succeeded. To make a long story short, since I had a recent Twrp backup so I did a twrp restore.
Rebooting after that caused a boot loop. I finally flashed a stock boot.img using adb and ended with either a boot loop or just the Moto image staying static.
I gave up and decided to do a factory restore.
TWRP is no longer available as recovery. I now get the dead android with red exclamation mark. I got to the options and selected factory restore with wipe user data. Reboot now gives me a static Moto image and nothing further.
I repeated factory restore with wipe user data 2 more times with same result.
How do I get a working phone again?
Please help. Thank you.
Hi there,
I had a similar problem with my phone a few days ago.
Did you try to flash back your stock os with a blank flash? for me this worked, I just had to make sure that ALL files of the Rom image were included in the batch/shell script. For me with a reteu image one was missing (I think the vendor.002 or something like that), otherwise my phone was also stuck at boot.
Maybe that helps! good luck!
Blankflash can be complicated; at least it was for me. Do a Google search, maybe, for LMSA. It's a software program from Lenovo (make sure when you find it that it is lenovos website) and download this app on your windows PC. Normally, and with a little luck, you can put your phone in fastboot mode (it instructs you through all this, too), go-to Restore and LMSA will download the most recent firmware and flash you back to stock. Hope you have some luck! if not I can try to be more helpful with blank / because it took me months to figure out and find a compatible one but I still have it somewhere.

I finally was able to flash stock rom again, re root and restore my apps with Titanium backup. I remembered a partially broken old phone I had and got it working. That relieved the stress of not having a phone and allowed me to work more calmly on my main phone. Still don't know why the twrp restore messed the phone up. Makes me bother why I'm using twrp for backups.

Hope you have some luck! if not I can try to be more helpful with blank / because it took me months to figure out and find a compatible one but I still have it somewhere.

I tried LMSA. It had entries for several Moto G7 phones (plus, etc) but not the plain G7. Strange.

I don't know if you still want to flash via fastboot, but there is a good guide for the g7 plus here .
You just need the last part, if your bootloader is working. Just keep in mind you need another image from lolinet, the standard G7 is codenamed 'river' as far as i know, so this should be the place for you.
And remember to check if all files (of the extracted image) are included in the 'flashfile.bat' to ensure the flash is complete, otherwise it maybe won't boot.
Hope this helps recovering your phone!

Hmm, okay. That is strange but maybe you have the G7 Plus variant? I don't know that model but the regular G7 is codenamed to (river) xt1962-1. So if you boot into fastboot (from power off; volume down and power held until the fastboot screen appears), look for the third or fourth line down, it will read something like "Product/Variant: river XT1962-1 64GB..." just to ensure that you are looking at the right forum/device. If you are still having issues and if all else does not prove successful, let me know and I can share the blankflash that worked for me along with the best instructions from memory on how I did it. My phone was once bricked to the point where no screen came on at all and I thought it was a goner (actually did it to two seperate G7s as I was learning why Lineage isn't my favorite custom ROM at the time lol) so I know the blankflash I have will work but I would recommend it as a last measure due to the fact that any and all data will be wiped so you won't be able to hold onto anything that is on the device's storage, itself. Hope you got it fixed and wishin you luck!

Hi there,
I had a similar problem with my phone a few days ago.
Did you try to flash back your stock os with a blank flash? for me this worked, I just had to make sure that ALL files of the Rom image were included in the batch/shell script. For me with a reteu image one was missing (I think the vendor.002 or something like that), otherwise my phone was also stuck at boot.
Maybe that helps! good luck!

Hey there; do you happen to have a page or website handy that explains blankflash and how the script runs? I remember there being so much confusion over it such as some people had me thinking I needed to find an external firehose program, codes, etc., and as it turned out I only needed the correct blankflash. I was able to fix my devices a couple of months ago but I was just still a bit curious as to the behind-the-scenes details that the software runs in order to be such an awesome fix. Thanks, in advance. Take care!
Fortunately I was finally able to download the latest stock android 9 from Lolinet and flash it to the phone with fastboot. I rooted again with Magisk, flashed copypartitions, and restored my apps and data from a recent Titanium Backup. So I am good now. But, it was very stressful for 2-3 days because I'm not an expert.
Yes the phone is river XT1962-1 64GB, but for some reason my LMSA did not recognize it. Extremely strange but unimportant now since I'm now back in business. I don't know for sure what happened but I suspect it may have had something to do with Moto G7's A / B partitions getting mixed up.
LMSA needs to be updated if there is no Moto g7 option. I just checked on my install and the option was there.
Has anyone ever actually used a TWRP restore? I have tried numerous times to no avail. It's rather annoying but I hope it'll get fixed one day to do backups/restores...same goes for adb backups.

I've successfully used twrp restores several times on previous phones. Saved me many times. But they were all on Nexus phones and earlier android versions.
The only time I used it on the Moto G7 I got stuck in a bootloop. Maybe it's the newer A B dual partitions causing my problems. Don't know for sure. But without a dependable system restore capability, twrp loses its value to me.
Now I am even afraid to try another twrp restore as a test in case I get thrown back into a boot loop. See my note on

Random bootloaders coming up flashing but no rom and no data on sims card

This oneplus6t is gettin on my nerves. Everytime i do the same thing it does something different. when i put on twrp and flash a rom i get this new bootloader that doesnt really let me do anything. Sometimes it just keeps going into fastboot. when the new bootloader comes up i got to put twrp back on and after doing it like 5 times i get tired of it. Is it a partition thing? Why is rooting so much harder then when i did it a few years ago.....................
Anyway i need help getting a rom on my phone. Thankfully the phone seems to back up oxygen cuz after a few factory resets oxygen just RANDOMLY came up even though i flashed another rom. TWRP and magisk is on the phone. Im also trying to get data working on my phone. I took the sims card(Verzion) out and put it in my Sgalaxy 7 for the time being and data works just fine on that.

you're using oxygenos on your other slot now, did you format data before or after flashing your rom? if you haven't then that's why you keep going to fastboot/bootloader mode
@O.P.P.
There are other AB partition devices that are much more of a mess to use. ?? It's one of those things where you have to understand it. It took me a minute and I bricked a Motorola G7 Power a few times during my quest to learn about AB partition devices. Thank God for Blank flash files and all the people who helped me unbrick my G7 Power more than a few times. I guess I'm a slow learner. I feel your pain though. One day it just all made sense for me after reading countless information about it all. You'll understand it. Made me feel really dumb when I finally did.
I recommend reading Funk Wizards guide over in guides section of the forums for OnePlus 6/t. The data not working ...I Are your imei # present or are the gone? In that guide the op tells how to backup your efs using terminal commands. If and when you get your device working again I would most definitely get those backed up and throw them on your PC or usb drive or a cloud or all of the above. This is important because if you have a situation come up where your imei is gone and you have no data you can fastboot flash these backed up bin files to your device and restore your imei and get data working. I've read there has been some users who didn't backup these two bin files and we're not able to get data and imei restored.
How I install a rom on my converted OnePlus 6t. This installation process varies depending on whether or not whatever rom I'm installing comes with gapps and or TWRP and of course you don't want to install global OOS on another model device. Since I converted my T-Mobile OnePlus 6t using guide and msm tool I now use global or international OnePlus 6t roms, firmware... Example Pixel Experience rom installation:
Boot TWRP
Flash OOS 10.3.6 global from repo xda thread
Flash Pixel Experience rom
Flash TWRP installer zip
Flash finalize zip
Format data
Reboot system.
Start to set up device then at some point enable developer options and usb debugging and doable any lock screen and boot twrp and flash magisk for root and reboot system. That is how I install a rom that has gapps but not twrp included in rom zip. Finalize can he found with a quick search on xda. It copies firmware to other slot on your AB partition device so that you don't have to. Saves 5-6 minutes and works great.
I would head over to msm tool thread and maybe give that a go. Msm tool is an awesome tool and much of the time a last resort depending on what's going on... If you have a T-Mobile model device be sure and use the patched tool. You'll see all that on msm tool thread. Hope this helps some..
Edit
Sounds like maybe you needed to format data after your install process. If you don't it usually sends you back to twrp or bootloader mode ..
