Download mode loop - LG G6 H870I - LG G6 Questions and Answers

I have a LG G6 H870I, different than all the variants I've seen here. That's why I'm posting here.
I tried to flash a .kdz ROM, via LGUP, that was older than my stock one. I read in the lg-firmwares page that if you try to downgrade, you'll brick your phone. That's what happened. I got stuck on the download mode.
All the times I tried to flash, I got an error message, since the first time. It never got completed.
The only time that I got it done completely, the phone started, but the Android circle that loads the first time you turn on the recent rom that you installed just crashed and it booted again to the "LG G6 Thinq" screen, and It never passed that.
I tried to hard reset, the hard reset screen showed up, I've put "yes", confirmed, and it booted again, but It crashed again on the circle thingy and rebooted to the "LG G6 Thinq" screen again.
All that I tried after that, I just got stuck to the Download Mode.
I tried 4 different roms (.kdz) with the LGUP, both 1.14 and 1.16 versions. I tried with UPPERCUT, without it, I've tried extracting the dll from the .kdz file and putting on the LGUP's "model\common" folder named "LGUP_Common.dll" manually, and the 8994 folder and dll. It recognizes the phone and starts, but every time I got an error message at 20%, 40%, 70%, even 99%.
Tried to reboot it, and still on the Download Mode.
After I trying so many times, now the percentage bar of the phone on download mode stops on 12-14% and gets back to the beginning and the LGUP or LGBridge just gets an error message.
The problem now is the bar percentage. It goes to 12-14% but crashes and it gets back to the begging. Now I can't flash anything at all.
I'm desperate. That's my personal phone, and I don't have a single clue of how to debrick it. I really need it. I have this one only.
Can anybody help me/save me?

LG G2 Bootloop, No Recovery, Download Mode Issue

I'm completely stuck here. Download mode works, R&D test tool doesn't work properly. It runs fully, I get no errors, but then it launches into a bootloop on the white T-Mobile screen. I don't have a recovery anymore since its flashed the kdz file multiple times already, it just won't boot. It still shows as rooted, though. What can I do from here? I've tried to find a solution in the LG G2 stock firmware thread but there's nothing at all related to my issue.
I managed to boot into the LG recovery. It runs for a couple seconds then just goes to the LG splash screen then bootloop at the T-Mobile white screen. I've tried the R&D tool with all the different settings like emergency, different country, different files, compatibility mode for windows xp, etc. Nothing works.

[Q] Stuck in nonworking Download Mode

Hey guys,
My T-mobile G2 (CloudyG3 before it got bricked) is currently stuck in download mode, and I mean that's the only thing it can boot into. Vol - and power gets me into factory reset screen, but when I go through the steps it just ends up booting back into download mode.
I'm trying to flash stock .KDZ files with LG Flash Tool 2014, but to no avail. I have tried all of them from http://storagecow.eu/index.php?dir=Xda%2FLG+G2%2FStock%2FT-Mobile+G2%2F, but a " *version #* - NOT SUPPORT" message shows up everytime in the box.
I have also tried the other flash tool, the one that uses .dll and .tot, and that one also gives me an error before the automatic flash process starts.
Basically, download mode progress bar has never budged a single percent in all my numerous tries.
Any advice is greatly appreciated

Sm-g900f (uk) galaxy s5 - arrgghhhhh

Can anyone PLEASE help??
My partner opted to do a suggested update on her S5, but didn't notice the wifi was off. The phone seemed to have done the update, but shortly after it rebooted itself, then again, then again. The frequency of reboot got quicker and quicker and now it loops between the Galaxy S5 splash screen and the SAMSUNG logo, but doesn't go any further.
I managed to boot the phone into reset mode, cleared the cache and then did a factory reset, but that did nothing to prevent the boot loop.
I then downloaded Odin (ver 10.3.7) and what I believed to be the correct firmware (G900FXXS1CPLV_G900FVFR1CPJ1_G900FXXU1CPIW_HOME.tar.md5).
Having checked the battery was charged, I followed the instructions of connecting the phone via USB, loading the md5 in the AP, checking Auto Reboot and F-Set time in the options and clicking the Odin Start button. I had removed the battery, replaced it and then booted it into the update mode (Power, Home, Volume Down, then volume up) with the screen confirming I was in the right place (....do not unplug.... etc).
The file loaded, (green bar at top of the Odin window on my PC) and Odin reported success. I then disconnected the phone, booted in recovery mode, reset the cache and then did a clear data, factory reset.
The same symptoms prevail, STUCK IN BOOT LOOP!!!!
The only thing different is that if I plug it into the USB on my PC, after a while the phone tries to turn itself on and goes into either a boot loop or freezes on the Galaxy S5 Splash screen or the SAMSUNG Logo.
I am charging another battery (just in case that is in some way to blame) and will try again to replace the firmware, but could I be missing something, do I need to do anything with PIT (I thought this was all taken care of by Odin using the MD5 file) or is there some other test I can perform that will show if the phone is fried???
MANY THANKS for looking!
ur going correct, try to reflash it again through odin and dont disconnect phone until it boots into system, it is taking some good time, so just wait and dont do anything this time like clearing anything or restoring. i hope ull get success.
THANKS - but...
Thanks Rayzen, I will try the whole thing again, but I think there is something more to this than a firmware fault!
There and gone again
OK, so on the 4th attempt I got the phone to take the firmware using Odin, it reported success and the phone rebooted itself (several times) and eventually appeared to boot to a new factory reset.
I put in a SIM card and entered my email and google account details and left it charging over night. This morning when I tried to use it, the screen froze and then it rebooted itself. Hey presto, the phone is back to square one with a boot loop.
ANYONE (please) got any suggestions?
THANKS
No one??
same here, same symptoms, same feeling.
when flash gone right... i feel lucky.. but for half hour only, rebooted and angain in boot loop.
I cannot even boot in recovery. flashed TWRP. from 5 boots in recovery only 1 success.
When trying to wipe phone in TWRP - it hangs.
still trying to install some other (custom) rom. still no success.
hope never dies
same things happened here! now cant get samsung galaxy s5 to boot...............
Are you sure your using right firmware? as it took me a few versions before it booted last time this happened?
Could any please confirm what is the right firmware for samsung galaxy s5 900F
It took another 6 or 7 attempts, left it over night and was about to trash it when it booted.
I then received a 'software update available' message and tried installing it. First attempt put the phone back into boot loop so I reflashed it again using Odin.
That worked immediately the over the network software update installed and now phone is 100%
Very frustrating but I got there!
glad you fixed it! ive tried three different firmwares and still nothing.
trying this one atm
G900FXXU1ANE2_G900FEVR1AND1_G900FXXU1ANE2_HOME.tar
oh and how long do they take to boot when there are sitting at the samsung glowing screen?>
I'm in UK and used what (I had to guess) was the best firmware.
I'll let you know which version it was when I get home tonight.
BUT I had all the problems with a single version and it eventually came good.
I read somewhere that overwriting a different core (from specific providers) with generic firmware, could lead to a world of pain until it gets full replaced... not sure if that's a good description (or has any fact to it) but it seemed to be re-loading and re-loading and re........ for ages, finally cracked it.
well mines booted now!but getting constant errors about samsung push!
If it'still booted, you'very made progress!
Push issues are mentioned elsewhere and can (eventually be sorted) but if you have a booted phone you should be able to get an over the air software update installed from the service provider....?!

Help my LG L FINO D290n stuck in boot loop - download mode still works

Yesterday my lg was working just fine. Before i went to sleep i locked my phone at the time battery was lower than 5% perhaps while i was sleeping some important update started but because it was such low battery the update got interrupted when phone lost all the battery. When i woke up i started charging my phone. After a while i tried turning my phone on but it was stuck in boot loop.
Tried phone factory reset but that did not work it got me to the lg welcome screen with language selection option but pressing next does nothing. I noticed that downloading mode still works on phone so maybe something can be made there saw this guide https://forum.xda-developers.com/d290n/how-to/guide-reflashing-stock-rom-d290-d295-t3142456 but i am stuck on step 3 Download a KDZ firmware file that site has adfly links and many links there i tried dont work.

Cannot complete any flash using LGUP/LGFlashTool. Phone shuts off every time @ 15%

Every time I try to flash a TOT using LGUP, it gets to around 15% and my phone shuts off, then goes to black screen/Qualcomm 9006 status. I then use SRK Tool to unbrick and try flashing again, but nothing changes. Same result every time. Also same with 2 different versions of LGFlashTool. Have repeated this process probably 100 times now with each of the three D800 TOTs provided here in user hyelton's thread: https://forum.xda-developers.com/showthread.php?t=2432476. It seems nothing will work. Am I holding a paperweight?
P.S. I previously flashed LineageOS 14.1 over stock 5.0.2 using TWRP. That seemed to work, but then every time I tried to flash GApps the phone would suddenly reboot. It got stuck on the LineageOS boot animation/wouldn't boot. Did I mess something up there? Partitions or something? Is there a way to fix this so that a flash will complete? I'm just trying to get a working phone back now.
Any help hugely appreciated!
