I know that there are many threads already about the tab s4 and other devices bootlooping but every in thread I saw the device also shows an error of some sorts or you can enter the recovery mode.
In my case it is a bit different, as I think it was caused by me being stupid and accidentaly deleting something I needed to boot with the universal android debloater. I deleted one partition that had no discription but seemed save to me but oh well. After deleting the package with UAD I used it for a while and the only reason I restarted it is because some app (i think overdrop) had a notification that I need to turn of battery optimisation for it and restart my tablet. So I did that today in the morning and in the beginning everything looked fine. I wondered why the Samsung logo was on the screen for so long but decided to let it do its thing. Then there was a menu that said something about it not being able to boot and told me what to do in 3 Steps: 1: retry the boot process (which just brought me back to the same menu); 2: reset the app data/cache (which seemed more promising) 3: contact support (which i didnt do because i feel like they would just tell me that they cant help me with that because its a device from 2018 and i used an "illegal" tool). So i reset the app data/cache and then tried to boot it up again. Then it bootlooped and I went into recovery mode and tried to hard reset the tablet hoping that the missing package would be restored with the factory reset but thats not a thing appearently.
So the things ive tried to solve this issue are:
using adb/aud to restore the missing package (didnt work because despite some thread saying that adb can be accessed while bootlooping I couldnt so that isnt gonna work)
Force shutdown and boot into recovery to look at the log and find something (I cant even get to the recoverymode anymore because the keycombination would just "restart" the booting process)
Sorry if my english isnt understandable, it isnt my first language

Hello there good folks of XDA,
I'm at work right now and my phone is at home but here is the story of what went down last night.
I tried to root my phone, after installing TWRP and superuser I ran a root-check app and it said that I was not rooted, so not thinking I tried the 'fix permissions' function of TWRP and then everything went haywire.
It's an international version M8 that I've had rooted before but reverted back to stock to get the lollipop OTA updateBy haywire I mean the phone booted up but no widgets displayed and most of the apps still appeared in the app drawer but nothing would open.
Instead of seeking help at this point I went to town on trying various things :silly:
The last of which was try and flash a boot image to it, but I think I must've used the wrong one as after doing that it's now stuck in a boot into TWRP loop.
From when I had previously rooted the phone I had a boot image (I think) 2.22.401, it matched version on the recovery file I used when reverting to stock in the past so I thought it would be fine
I've still got a terminal open at home with all the results of the fastboot getvar all command but from memory my CID was HTC_044
Can someone help outline the process and possibly even the files I need to reflash my phone into a working order. (it doesn't need to be 'stock' but that would be best)
I use a mac by default but I do have a windows machine at the ready I can use so feel free to base any tips on doing it from either platform
Post the getvar all output, minus IMEI and serial number, and we'll go from there
Thanks for coming to my assistance but in the end (after a few more slight failures) I managed solve the problems myself.
I believe that my first problem was using a not up-to-date version of TWRP (2.7) with Lollipop; the first symptom was my attempt at rooting my phone, the process appeared to go well but just wasn't working properly.
My second problem was 'fixing permissions'; after doing that my phone went totally haywire and while it would boot into android nothing would work properly
After going to a previously used stock recovery and getting nowhere I went back to the same TWRP I started this with and still had fixed nothing.
at this point I did a factory reset from the recovery mode and while that got me booting back into android I was being swamped with error messages and couldn't get past setup wizard crashing.
At this point I flashed the wrong boot image and had a nearly impossible time getting to the system boot menu instead of TWRP being what it always went to. Eventually I must've got the timing right with the buttons or something because I got back into the system boot menu and could access fastboot.
Once in fastboot I downloaded a full nandroid backup and restored it, my phone was working again... or so I thought, it was still suffering from permissions problems
at this point I re-rooted it with the latest TWRP, got SuperSU working properly, did the 'restorecon' command with a terminal app and now the app crashes I was getting have stopped and I can see and write to the phone memory.
After trying to test everything I could think of on my phone today I think it's finally fixed.
I tried to do a partial/selective app+data restore from a nandroid backup I took of my own phone just after the 'fix permissions' event but it didn't work properly so in the end I manually re-setup my phone. I do run an sms backup app so overall I only lost time...
So everything was working well no issues. The other night I am playing a game and everything seemed a bit wonky the touch screen was erratic and the graphics were stuttering so I figured I hadn't rebooted in a long time may as well. Well now the tablet just boot loops and won't come up. I tried doing a factory reset in recovery that hasn't helped. I hadn't gotten the time to try out the custom recovery so I have no backup is there any way to reload this thing from a computer or do I have a brick?
Little back ground I was rooted but no new software was installed in over 2 weeks prior and even upgrades had been at least a couple of days and then just Google stuff. No issues up till this point it was working very well. I was on Lollipop but would be happy to boot either KitKat or Lollipop at this point.
Little bit ticked off the tablet was only 6 months old never abused/dropped at all. I kept it in a sleeve when I wasn't using it and have a case as well. I don't install suspect programs at all. I use the tablet everyday for both work and personal use so I really need to get it going again if possible.
So I found this program called B2CAppSetup.exe in a post for the lg tablet 8.3 I installed it and put my tablet in download mode. It said that my tablet was up to date and that nothing needed to be done but there was an option to "update recovery" which downloaded a 1gb plus file so I assume it was the whole OS and not just the recovery. Took a while to do the reinstall but it did work, first boot took a few minutes but my tablet is running again. I will have to reset everything up again the way I had it but that is OK I had made a backup of my apps and data about 4 or 5 days before this happened so anything lost will be minimal. Hope this is helpful if this happens to someone else.

Well if I can just find out exactly what I need installed on the computer and how to enter the commands and where to enter them I'd be alright. Its been a long time since I use a computer and I'm stuck in a boot loop for no reason at all except for I rebooted and it is stuck. Can't go past fastboot or recovery or that screen with the big barcode. I did nothing that could affect the operating system and only had some very simple route adjustments made so I don't understand why it is so messed up. But hopefully someone can explain the computer part of this and I'll be straight

So, Lately I've fiddling with my quite old 'spin-off' awkward phone. It's a "GT-i9063T" a different 'version' of the i9082 it's exactly the same, all the same specifications and physical size, screen resolution, everything. BUT (I'm not sure of the next statement since I had only one reference) -- The processor's name are different, even tough both have EXACTLY the same specifications.
And also, most importantly, the main difference between the two, is a useless "TV" function. It can capture (sorry not sure about that verb, I'm not American) average, analogical TV signal, and I never used it.
Since it's SO equal to i9082, i was like, FU*K it, let's use i9082 stuff! And, NOTHING, happened.
My first attempt was to normally odin-mode boot, and then change/flash recovery mode so i could install the ROM through there. The thing is, the TWRP (only recovery that I found who supported i9082) did nothing. I install it normally, no errors pops out, (it's almost instantly) odin even say it were successful, but when I reboot and actually try to enter recovery mode, the stock recovery mode is still there. My guess is: I got this spin-off of mine through a plan (those 6 months contracts and they give you a free cellphone) with Tim (the huge Italian communication conglomerate) And I'm guessing it's bootloader might be locked.
Then what i tried was: Flasihfy, the app crashes when i click to choose archive, then i tried to 'bootloader' mode and i couldn't find how to boot to it (no key combo neither ADB worked) and I think it's not a thing for Samsung devices.
But I know that, the fact that, my phone is a different model and i9082 stuff won't work on it just might be the answer.
So, help on getting a custom recovery on? Anyone? ;-;
PROGRESS! Actually, a verdict I think, I found out that, stock rom's replace the recovery on-boot, i haven't found ANY GUIDE mention that detail. So, knowing that, I tried again the TWRP for i9082, it bricked the recovery. The boot froze when I tried to access recovery mode and the red exclamation of death appeared, I even tried to let it load for a few minutes, try again, but NOUP, nothing. It did brick the recovery mode, then I let it boot normally, it did, replaced, my custom recovery and Voilà. Back to square one. BUT NO! I MUST CONTINUE I CAN'T LET MY DREAMS BE DREAMS, YESTERDAY I SAID TOMO... So I've started looking to see if I could find a recovery specific to i9063T, and I did, found one on a YT video, I flashed it booted into it and it worked!! So i've started the process, by trying to wipe/factory reset, then i found out the partition table of the CWR i found was messed up and it couldn't wipe the data. SO i reboot, let the CWR replace the stock recovery (it asked permission) and booted normally, restarted the phone and tried to boot onto it again, only to find out it had been replaced anyway ):
Veredict: i9082 stuff won't work because the partitions are different named/organized.
Okay, So let me start from the beginning so I'm certain I'm being descriptive enough.
The other night my G3's wifi stopped working. When I went to turn it on in settings it would turn itself back off. Which I thought was strange. So, I assumed it was a software issue so I backed up any important items and factory reset my phone last night. That went over fine. Wifi worked again, all was good. Until, it said it needed an Android Software Update. I hit "update" and allowed it to do its thing. About halfway through the update the phone said "error." With an icon of the Android bot with a hazard triangle sticking out from it. I let it be for a bit and nothing happened. So in my impatience I took the battery out and put it back in and tried to restart the phone. This is where the issue occurs. The phone keeps booting to recovery mode. I'm not savvy at all with Android so I don't know if these mean anything but it says "Android System Recovery <3e> LRX21Y" The phone has had zero modifications done to it. I would really appreciate any help or any tutorials that could save the phone until my g6 preorder comes in.
Thanks!

Your phone failed the update for some weird reasons and is now stuck. I'm afraid you'll need to restore stock Android using LG Flash tools and KDZ files to your device. It will get your phone working, but you'll lose your data in the process.
You can try mounting the phone from recovery or download mode and see if you can access your data and backup the data. You can also try the recovery option without downloading wnloaing a KDZ first.
You can fins tutorials around the forum, in the general section usually.
Hi guys, bit of a saga here so bear with me...and also it should be mentioned I have little experience/understanding of tech stuff, so that isn't helpful either lol
I've had a Nexus 5x running 7.1.2 for not quite a week; it came with an unlocked bootloader (strangely). Tried to do the usual install twrp & root as I've done with previous phones (all pre-nougat) but all attempts failed. Couldn't boot into stock recovery from the bootloader at all, it would just boot into the system. OK, next thought was that an OTA upgrade to Oreo might work to restore a recovery - but got the BLOD (naturally lol). I found a fix in a modded 4-core Twrp 3.2.1 -0 fbe img + workaround injector zip from osm0sis & XCnathan32 which by some miracle worked.
So far, so good. Ffwd a few days and google play store keeps crashing on opening; I had the feeling that some glitch happened while it was updating, so I tried all the usual fixes like app cache/data wipes and uninstall updates/renistall google play, delete google account etc which failed. Next I tried a cache & data device wipe through twrp - also unsuccessful. Finally, I thought the only thing left to try would be to restore a backup I made on twrp - this led to the current issue of not booting, stuck on the google logo screen. I even thought what the hell! and attempted a factory reset with twrp - same result, where I am now. Google logo screen, however I still have an unlocked bootloader.
Would anyone be able to suggest where I might go from here? I'm pretty sure the version is N2G48C, if that helps.
Any suggestions very much appreciated...wouldn't mind getting to the 1 week mark with a functioning phone lol
Saga #2
Still no idea what's going on. I realised that I'd backed up and recovered the system and vendor .img files, which according to this thread would be a cause of the issue https://forum.xda-developers.com/nexus-6p/help/stuck-google-logo-twrp-backup-restore-t3320840/page3
So I made another backup without those images, did a full wipe and restored it - still does not boot, still only sitting on the google logo. Tried next to open a cmd terminal to see if I could reflash a stock image, but adb could not connect (maybe because the phone would have been on charging and not file transfer mode?)
Last resort as I saw it was to try the NRT, and see if it would flash stock via the bootloop/softbrick option. Process seemed to be OK, judging by the log - but it did not reboot to the system. Now there is a looping bootloop between the google logo and the unlocked bootloader warning.
Following wugfresh's instructions to factory reset from the recovery (the phone won't turn off via the power button so I just booted straight into the bootloader) Looked for the recovery option, selected....and nothing!!
So there isn't a stock recovery??? How does that work?
And what hope is there for this phone now? (I can't think of anything else )
Anyone have an idea? I've never heard of this before tbh!
Well, my problem has been sorted. In the absence of knowing what the hell I should do lol I managed to get a refund for the phone even though it was a refurb to begin with (something to be said for an honest seller who provides a 3 month warranty!) and I picked up a brand new N5x, which was unboxed on Tuesday. Not even 6 hours into setting it up, the phone started to get progressively hotter and then went into bootloop. Got into the bootloader and tried a factory reset - all seemed OK but halfway through the setup process it bootlooped again. Fortunately it was still within the 2 year warranty, and LG didn't argue about authorising a repair for a phone which didn't get even half a day's use on it lol
Authorised Wednesday, walked into the service centre Thursday and a 1 hour wait later had phone in hand with the PCB/motherboard replaced. Has been working fine (and cool!) ever since. Definitely feel lucky to have hopefully dodged a bullet on this one.
Bonus that they upgraded from 6.0 to 7.2.1 while they were at it; apparently LG considers nougat the "latest" stable version for the 5x.
