[Completed] Phone is not recognized in Download mode. - XDA Assist

Hi,
Knock on is not working on my LG g2 from past 2 days. I tried factory reset knock on/off toggle, device test, calibrate sensors. Finally I decided to return the phone but I need to unroot it for that.
As I cannot follow the usual process because my phone is not recognized in download mode via USB (both pc/linux) I tried installing a stock rom(80020k) and then uninstall the root. also I replaced the rtc files and the I tried to update the phone to D80020u but it fails with error saying device is suspected of rooting.
I became over smart and flashed a stock recovery which won't function.
No root, No recovery now. Tried rooting with ioroot25 doesn't work because it requires a functional stock recovery.
Any help/suggestions that can get me back to stock?
Thanks.

[Completed] [Q] flashed the wrong radio.zip... can i fix it?

I accidently flashed the zv5_radio.zip (which i downloaded from the root all the volts forum thread titled zv5 full update- odexed and deodexed for my own phone, an lg volt ls740) onto my husbands lg tribute ls660p, and now the screen stays blank. It still makes the boot up sounds and notifications as if its booting correctly and the computer still recognizes it, but if i try rebooting it to recovery or download mode, i have no idea if it works, and then the computer doesnt recognize it. I recently rooted his lg tribute and flashed twrp as the recovery.img successfully before flashing the volt radio.zip, the computer recognoze the phone in adb, but any rebooting stops that. I have no way to allow my computers rsa key on the phone either ive yet to find any .tot files or .kdz for the ls660 (stock or otherwise) or any .dll files for the lgflashtool either, cause im hoping that might be the answer. Please help. Or possibly a stock rom? The adb shell on the computer also says the device is not rooted or you do not have permission to do that, please help i read that i may have.overwritten tne aboot.img, but no luck finding any of those either. Thank you

[Completed] HELP! I think i soft brciked my S6 edge(SM-G925F)

Hey!(Sorry bear with me i'm a newbie )
So, a while back i rooted my phone using Ping-pong root and after a while i un-rooted it, Using theSuperSu unroot function.After,that whenever i got an OTA update to 5.1.1 and tried to install it the phone failed to do it and asked me to use smart switch.
I did as it told me to and tried upgrading from smart switch.Even smart switch tried and failed to update the firmware and now i'm stuck with a caution screen saying "An error has occurred while updating the device software.Use emergency recovery function in the smart switch PC software".
I've tried doing that a several time and haven't had any luck.Then, i tried flashing the stock firmware using odin,It kept failing.
Please help!I'm going MAD!
Thanks in advance

[Completed] ZTE SPro Bootloop

Anyone who has ZTE Spro Smart Projector MF97W here? The device is stock rom but rooted. I've never tried altering the system app. But one day, It got bootloop because it got freeze after playing COC so I press the reset button. I don't know what is really the cause of the bootloop since I've never change any system files.
I think I need to flash the firmware of this device but I found nothing.
I've already tried factory reset via recovery. Adb won't detect the Spro.

[Completed] Feb. 23, 2017......Please Help

Please help, i have been everywhere on the net and tried every possible method presented. adb, side load, factory reset, wipe/cache. nothing works. rooted my phone, later unrooted because i was gonna take it to be fixed because softkeys stopped workin, but downloaded button savior instead. then eventually wanted mt phone root again. forgot to adb "reboot disemmcwp" first. long story short, bricked phone, stuck at zte logo. i can enter the recovery mode. but it will not allow me to update from sd card for some reason. my usb debugging is not turned on. and most importantly I cannot for the life of me find stock rom or any other rom for this damn phone. as mentioned, i already did factory reset and wiped my data but it did not solve issue. i read in another forum that disabling certain apps could cause a soft brick after doing a factory reset, i did have some apps disabled. so dont know if that is the cause. I know how to flash firmware, roms, and recoveries. But i cannot find a custom rom, or a custom recovery for the ZTE Prestige N9132......so can someone please give me a copy of the stock firmware, or kindly direct me as to where i can download it???? I have scoured the internet for literally 4 days now and cannot find any firmware for this model phone at all......PLEASE HELP!!
I would be satisfied if i could even get a custom rom or recovery, if not the stock firmware would be fine. just please show me where i can download it from
Hi !
Unfortunately there is no dedicated forum for your specific device that more users can gather and discuss
We don`t have a firmware section here on XDA , if you want to request it you may do it here https://forum.xda-developers.com/android/help though I see that you have already done it here https://forum.xda-developers.com/showpost.php?p=71152939&postcount=5
So let`s wait for users with a similar device to reply
Good luck
