I had an experience as bad as yours. After flashing the last miui.eu, I went to boot and the phone does not leave the boot right away. I tried to enter TWRP and the touch just didn't work. I ended up flashing the official TWRP, also none of the touch works. I started getting desperate and settling for formatting for ROM stock and losing my 2 year old data, because I went to fastboot and flashed stock 11.0.8.0 and guess what? the touch didn't work, even in stock, I started to go crazy. So I had the stupid idea of ​​putting the stock and blocking the bootloader, I ended up ****ting even more because even after the flash and blocking the bootloader the touch was dead. I was already giving up and thinking about paying someone as access to EDL mode to restore the phone. I ended up seeing your post and had the idea of ​​plugging a mouse into the cell phone's type c input, and believe me the mouse cursor worked. Then I managed to unlock the bootloader again and flashed the stock that you recommended, and voiala the touch went back to work. I ended up going back to miui.eu and I'm ready for new flashes. It seems that we like to suffer LoL. I think this topic should be fixed at the top in case anyone else falls into this insane problem.

Reflash firmware n try ones.. only firmware

Im having the same issue.What should I do??My touch was working totally well before flashing TWRP.

solved by plugging in a mous in TWRP and navigating the UI to restore my "full" backup of all partitions! if you have done a backup! cheers and thanks for the idea of the mous! not expected it to work in TWRP though!!!

Help! Flashed Mi4 ROM and my phone is now half-broken

Hello friends,
In a moment of a severe mental handicap, I appear to have flashed a Mi4(cancro) ROM in EDL mode when I was trying to unlock my bootloader.
(The reason was that the guide I was using had a broken download link, so I searched for the filename and downloaded from one of the mirrors I found. I did not realize I was now downloading a file with a different device prefix (cancro instead of kenzo.).
So after the unavoidable brick, I was able to recover by flashing a proper Kenzo MIUI rom with disabled device checks (Since the phone now thought it was a Mi4, I guess).
MIUI is booting, but most of the functions are broken:
- No camera
- No SIM/Service
- Can't adjust brightness
- No rotation
Maybe there's more stuff broken, but I did not check every corner.
I moved on to try CM13, but that won't boot up at all (just sits there at the boot animation).
So far everything I've tried to get the phone back into a working state has failed, but I'm still getting used to this phone's specifics, so I may have missed something.
Please tell me there is something I can do.
if you can get to the recovery then WIPE everything out (system, cache,etc) then install the stock MIUI for your note3, if it booted up then you can move on to any other Rom...

Thank you. I can indeed get to recovery, but I always end up without sim card and camera when I flash an official rom.
I just tried to go back to the shop rom from geekbuying, that at least made brightness and rotation work, but still no signal/camera. I feel there's some firmware missing or was overwritten by my stupid action and now there does not seem to be a simple way to get it back up.
EDIT: So I just found out that my IMEI is gone. I will try to use a guide to re-set it. Hopefully, that will get mobile service running again. Dunno about camera, though

Need help, endless reboots

Was running the unofficial lineage 14.1 rom, was getting frustrated with all the gps problems so I decided to try fulmics. Well cell service didn't work on fulmics, so I wanted to switch back and tough out the gps problems until lineage team got things fixed. Recovery seems to be working fine, but any rom I try to install simply endless reboots before every getting to the initial set up. I am at a loss, I am thinking I didn't have the new lg bootloader as I was told to have before trying to install fulmics. How the hell can I fix my phone? I always thought as long as recovery worked I would be fine, but that doesn't seem to be the case. Anyone help before I have to go out and buy a new phone tomorrow?

PMd you.
I found a fix, I completely wiped everything and first flashed just the stock 7.0 lg bootloader, now everything is working fine. Thanks for the message though!

No problem ?
Same Problem
I have the exact same problem. I flashed the LineageOS ROM, then flashed Fulmics ROM, then tried to go back to Lineage—and now every ROM just reboots endlessly, but I can boot into recovery and access TWRP just fine.
It looks like jamesvmccann found a fix, by "completely wiped everything and [then] flash[ing] just the stock 7.0 lg bootloader." I'm afraid I don't know where to download the stock 7.0 lg bootloader. This is a h830, so that may matter as well.
Any additional help would be greatly appreciated.
Managed to fix this problem myself
The stock h830 bootloader was linked in this forum post.
I booted into TWRP and flashed the stock bootloader. It has a different bootflash.
H850 keeps booting into Recovery
Hello everyone, I have a H850 and my phone does not want to boot into the OS. It keeps booting into Recovery mode. I tried flashing only the H850 bootloader and then installing a ROM, and it doesn't work. I've formatted everything except the SD card and still no joy. What else can I do to restore my H850?
Please Help!

I had same problem factory reset few times within twrp seem to work after a while. I take it your backup not working? If all else fails flash kdz in lgup
Sent from my LGE LG-H830 using XDA Labs

nothing working :(

well after somehow breaking the miui stock cam when enabling the camera2apk, and being unable to fix it by replacing build.prop, i decided to restore the backup i made in twrp earlier.
restored backup: sticks at MI logo.
tried several times, cleared caches, wiped etc etc.. will not boot after restore.
so i downloaded the stock global rom, and flashed it in twrp: sticks at MI logo. will not boot
downloaded Ressurection Remix rom, flashed that.. works fine. but i want stock or as near as possible for now.
downloaded developer miui rom, flashed that in twrp: stuck at MI logo. will not boot.
tried stock stable rom again... same story, will not boot.
downloaded Miflash, and recommended TGZ archive of ROM. followed instructions and extracted to a folder and browsed to folder with Miflash. hit "refresh"
get error "length cannot be less than zero"
tried using the "mi recovery" method (renaming rom to "update.zip" and power/vol_up)
but for whatever reason, there is no "install update" option even present.
as you can see im having a very frustrating evening. i only wanted to enable the damn google camera.
flash it by edl mode
Sent from my [device_name] using XDA-Developers Legacy app
is there a decent guide for that anywhere? from what ive seen it still requires miflash to be working? which it, frankly, just isnt. but then, nothing is! dont think ive ever had an evening where so many things which are supposed to work all give problems together.
i mean, i could understand if the custom rom was problematic, but its the only thing that *did* work.
404 Not found
well i managed to get a stock rom installed by downloading an older version of miflash... that didnt give any errors and installed the global rom fine.
i would love to know what could be causing all my problems though. seems everthing ive tried should work.
the one that is bugging me more than anything now is that whenever i enable the camera2api, the miui stock camera stops working ( crash on hdr, panorarama mode) and stays broken even if i remove mod.
this should not happen it seems, since there are guides for enabling this and adding the pro features to the camera from higher models.
nobody seems to have an opinion on it, which is very strange considering the number of people who must have done the camera2 mod...

I dropped miui long ago, so it is difficult to comment. However, the problem would probably be found in the settings (and/or the drivers in the system). Reinstalling a stock system image and wiping /data (and formatting it, if necessary) should solve the problem. This is, of course, a drastic step - but I would be very surprised if the problem persisted after such a step.
you have to flash lazy flasher after every MIUI stock rom flashing to be able to boot the rom...
google it "lazy flasher'

Proximity sensor issue!

Hey, recently i've been having issues with the proximity sensor on my vince. This started a couple of days ago when i decided i wanna go back to miui from custom roms and i did a full fastboot reflash. So basically i flashed everything clean without locking the bootloader.
And now the proximity sensor went nuts. (it was working fine until i flashed the fastboot rom)
It works, but barely. I gotta put my finger really close to the screen for it to actually work. So if i'm in a call it's annoying, screen is staying on since my ear can't get that close to turn off the screen, unless i press it hard against my head.
I've tried recalibrating it from miui, i've tried flashing different version of miui rom (both in fastboot and recovery) with no avail.
Also, i've removed the tempered glass i had on it and i cleaned its surface.
Anyone had this issue? Can anyone give me some pointers?

Try flashing the custom rom which you used before flashing the miui roms...it may work...

Did that, i flashed a plethora of custom roms and nothing changed. I've read some stuff and maybe it's related to the persist partition, but i can't erase that in fastboot (something about image not being allowed to download), tho i can flash it. I've flashed the persist.img twice now, once with a developer stable rom and once with a simple stable rom. Still the same issue.

Have you tried wiping the cache after the first boot of the rom (custom / miui)..?
If above doesn't work, try to turn off auto brightness(if enabled) and then check if the sensor works on call....

Touchscreen Completely Stopped Working After Boot TWRP

Hello friends. Yesterday evening I was going to flash my phone to stock rom. I opened twrp and the touch problem that I had encountered again. I reset the program again and again by holding down the power button, but it has not been worked. then my phone remained open in twrp. This morning I flashed my phone miui beta on miflash. (Android 8.1 9.6.24) The phone is switched on, but the touch issue still not working. If you could help with this situation, I would greatly appreciate it. Thanks.
Use otg mouse and format data, then install again nee rom or oficial miui

use this twrp for touch issues
https://forum.xda-developers.com/showpost.php?p=80122987&postcount=305
also use latest Franco kernel having different touch drivers! or Optimus drunk kernel
more oever Twisted kernel releases 3 variants on 3 types of touch drivers ,
you should find them in the developer section and try!
i have same issue i have factory reset using fastboot the display is working but touch isnt working ..
Use an otg cable in Twrp, install another kernel, this has already happened to me and the exchange of the kernel stock for a custom one worked
