Problem might be you are not rooted to start with and those apps don't work without jt

Well.. Flashing a different version of superSu wasn't good for my phone, 90% battery and while in the middle of flashing the phone freaked out and shut off then got stuck in a bootloop -_- lg's are retarded.. any way of fixing without data loss? or is it the only way to fix by flashing new system?

not sure what is happening but do this... use
LGUP not lg bridge.. download latest KDZ wich is 20v for tmobile when you are about to flash select refurbish option.

As of right now the device is unlocked and i bought the device refurbished so i have no idea on how old it is. and i used a rom for 7.1 that worked before and there was no problems until it started force rebooting.. i did some google searches and theres problems similar to mine but the fixes don't work for me

could it be that your phone its not a h811.. i mean it was sell as a h811 but inside motherboard its different.. but the part that bootloader is unlocked puzzles me. i asked if you unlcoked or came unlcoked bootloader..
only way to tell is to take phone apart and look at actual motherboard plaque number or variant.
maybe you have a h815 phone... i dont know.. a kdz and refurbished should it fix it..
its upto you if you want to open it.. i cant think of anything else.

Really late reply, But where would it be located on the board?
Everything identifies it as an h811 like android OS, googleplay, and i asked LG support on what the model is and they asked for the imei and the model no and they said its an h811 but i've been lied to by a phone company before so idk

You have to physically remove motherboard to see it
I have 810/with unlocked bootloader....at least I think I do.
Mine was serviced for power failure so it was T-Mobile now is ATT h810 that is all I know for now

Seems like h810 will take aosp/cyagenmod ROMs for 811/815 but not LG based

I'm confused Either LG labeled my device wrong or my device is just very compatible with OS's, The sticker under the battery says "H811" and on the motherboard it said H810 but it has had an official h811 KDZ flashed to it and roms for H811 ???

Yes you can flash and so convert a h810 to a h811 and then unlock like you do on a h811.
This does NOT work for other models like the h815 and even the above requires to take care of the ARB!
Hard fact is what deltadiesel described: your board. If you see there a h810 written it is one. The rest can be tricked by software that's why you see h811 in android.
PS: There exists one exclusion but this has not happened here.

Called lg for escalation department
Told them because they put wrong motherboard I can't use the network i want if it were T-Mobile motherboard. They asked how I know it is ATT 810... I told them I opened it. They said this voids warranty. I said you lie to me about what you repair my device with, that is fooling customer. LG repair facility is going to contact me. Repair will be free of charge as long as as there is no physical or liquid damage. I told hem well you cant sell a product fix it and then have a customer think it is the same product when it is not, if I didn't open device I wouldn't have known you lied to me. I was out of warranty either way, and told them you have info what device was repaired with when it serviced.... This is what you guys did.
:good:
Monday they call and maybe I get it repair for free, or they have no G4 left and send me G5. Lol that is unlikely.

It's a known issue with some device models. The device reports it's unlocked but in reality it isn't. Perform the normal unlock steps to unlock your boot loader despite it reports it unlocked.

So you can't even start your device i.e. it doesn't even reaches the pre-boot screen (the Honor logo). You should have never ever flashed fastboot image. If your device reaches Honor logo, then bootloader is fine and fastboot should work but if that isn't the case, you have screwed it up big time. Still do reply back, we'll see what we can do

jtag Box needs to be coupled with Bootloader flashing tool and the necessary bootloader files. Since none of them are available, you are in a pretty hard spot.

No my bro.it's Dead.you should change your mobile mother board with another honor 4x(it's expensive) or you should find a programed EMMC that exactly is for che-tl00h(almost hard to find for this model) or sell your hard bricked phone(best way like my way). Of course you can find your dump files and give them to a technician for flashing on a unprogramed EMMC,but I know you can not find dump files for this model easily.
This is a real experience for focusing on model of the phone that we purchase for next shopping.
We should just buy a Global released model,not a china model.

Factory Reset, start configuring language, dont connect any WIFI or DATA and Next button after this the screen show Configuring Phone, press volume up + volume down - home button and button back, and Woola bypass the stupid activation
This is the method
Thanks guys, I managed to skip this step. I founded tutorial on youtube, but phone must be connected to WiFI, otherwise there is no skip option only back to connect.
I have another problem, now it says that SIM card is invalid. I cannot connect to mobile network. It seems it is SIM locked, but I used current SIM with this phone and had no problems. Do you know guys is there some possible way to unlock again this phone without root? Again, I cannot contact Sprint because I'm not their user.

you might be able to try some trusted 3rd party unlckers no way to downgrade either or brick will result to try inter nat rom so thats not an option either and problem with some 3rd party unlock companys is sprint still has apns greyed out so not able to mod them some have reported ok but basicly now its a monetary risk and in my opinion the device isnt really worth investing any cash into except for the camera no root methods are available beyond zv6 firmware no downgrade possible
---------- Post added at 02:49 PM ---------- Previous post was at 02:46 PM ----------
you might look for sevice menu ## codes look for a setting that says itson and disable it may need msl code n wich is still obtainable throught sprint its hard work but i have done it many times
mayers unlock method sometimes requires manual diable of itson to get rid of invalid sim card notification
no root needed
I bringed my device in local service shop to unlock, but they returned phone more damaged. Device can't turn on and when I connect charger there is no charging indicator, nothing. When I connect phone to computer it is recognized as "Qualcomm HS-USB QDLoader 9008". Is there any solution to unbrick this phone? Any answer would help. Thanks!

I would take it back to said shop and raise hell they damaged it they need to replace it. What firmware were u on. It dont really matter. The firehose.bin for qfil to reflash fone doesnt work for g4. Unless someone has made a new one but i havent seen one yet. You might try lgs waranty. Claim to have bootlooped. Or something like that

I dont know. If i tear up someones phone im working on. Its kinda my obligation to fix or replace it. I do unlock what phones i can. Repair. Root and modify. I wo far have a perfect track record with customer devices. But. If it ever came about i brick one. Like said. I kinda feel obligated. Or is that not a thing but a courtousy?

Totally agree with you. But people are different.
I, too, have long ago discovered my telephone cemetery)

typing adb reboot bootloader only restarts the phone 20r

i have an h811 on a 20r stock rom and im trying to root it and install a custom rom but i cant seem to make it reboot into bootloader... everytime i try to do so it simply restarts... the drivers are fine and the adb identifies it... oem unlock is ticked and debugging as well
any ideas?
the h815 needs a key .. h811 should boot into bootloader .. is phone refurbished.?
Maybe im not sure
How do i confirm?
well am not sure either am just guessing it could be that. as it doesnt want it just reboot not sure if other variants does that.. the only way is to open phone and take motherboard and read the plaque model it should say there and thats your variant. you can wait for other answers am just thinking . with mine it does boot into bootloader seems you have everything set up. so unless its not a h811 as we dont need bin key to unlock. and h815 does.. not sure what a locked bootloader phone that cant be unlocked does when command is given
thank you for your reply...i just noticed sth weird ... kindly look at the image i uploaded here (( http://imgur.com/a/HCjEH ))) the serial is sprint and the model says h811... how? what is wrong here and im messing
well they can use i think ls99 its sprint mother board and edit the model number to h811 on the software. so like i said open it take out and see model number on plaque. if its says LS9 sprint them search to see what other have done. i think you dont have a h811. or i would return phone and demand a real h811
i took the phone brand new for around 100$ sealed... the company is located in UAE which i was in vacation in and i came back to jordan where im living ,,, it would impossible.. im fine with the phone ill have to find my way around it i guess...this way i should handle it as a ls99 not as a h811 i guess... thank you so much for your help brother
not untill you know for sure what you have on motherboard plaque.
search see what other people have done .. some go with what mother boardplate says.

{PLS HELP} LGflashtool stuck at 9% - Connection failed -

Hello everyone,
Im new at Rooting, but I'm good at following instruction from videos, forums, and whatever I get my hands on. I have an LG G4, that I recently rooted. There are some issue with Root, and some applications I cant run (like snapchat- I had tried with Rootswitcher and Magisk but failed).
I followed instructions from several videos and forums here at Xda-Devs. But nothing seems to work. I have download multiple firmwares but everytime i get an error. the lgflashtool14 goes up to 9 % and there is some logs in my phone, but everything stops.
Also I want to mentioned that this are the steps that i rooted
Please any help will be appreciated, I want to go back to stock. :fingers-crossed:
Edit : I have tried all variants of the firmware, some they not even get stuck they say " contact administrator "

then i think its not a h811. open up phone and take motherborad out see what it says on the actual motherboard in your hand, what ever it says flash that, maybe is not a h811

Hey man, I followed your instructions, and in one side of the motherboard says, EAX #####501_h810_main_1.0. Would that be the firmware im looking for.??
*edit : its weird since I look up the H810 is a ATT, but I got this Phone in Tmobile
*edit 2: by dialing *#*#244773825625#*#* it gives me this - HW version Rev1.0 - Factory Version LGH811AT-01-V20r-310-260-jan-11-2017-arb03-SW ORIGINAL VERSION *same as the factory version*- Anti rollback version 3-

go by what the motherboard says.. if you got it from tmobile return it.
yes seems yours its a att 810
motherboard is what determines your variant other things can be edited but not that number and printing on mitherboard
yes weird they might be refurbishing phone using other motherboards

Ok, but i might not be able to return it since its past the year. And with LGup I open the software and states that MODEL "unknown" and gets the COM port and the software im runing in a small window. Is there any fix for it, that you know of?.
