Unable to Reflash via LG Flash Tool

Hey all, thanks for reading. I've caught myself in a predicament. I can solve most issues that crop up my way, but right now I'm a bit stuck. It is likely fairly simple and I am just dumb...
The huge issue here is that I am running stock lollipop for the D415 model. I am having the typical base-band and WiFi issue that a lot were having. Like most, I just booted up into TWRP and restored a backup. I Wanted to try again so I flashed the stock ROM and tried again; didn't work...oopss..
LG Flash Tool refuses to locate my device. Download mode fails to connect my device properly. Error is:
EP1/out FAIL nfo=40 pg0=ffbd880
usb_read() transaction failed
So now I am stuck with a broken stock ROM, no TWRP, and no current way to re-flash a stock ROM.
Steps taken so far:
1. Reinstall all drivers
2. Attempt to root and install TWRP to access my backups (No access to Download mode)
3. Started all over with original USB.
What can I do? Thank you again for reading my long post.
Came back to it after a few weeks and issue has been resolved. Despite error warnings fastboot operated correctly, only manually. Any script etc. that booted device into fastboot would never find the device. Simple as flashing recovery and restoring a backup.
tl;dr: I'm not very bright.

Need Help. ADB, Recovery and Fastboot/Download Mode don't work

Hey xda community,
last night i run into a tricky situation.
First, I explain what I did
I bought me the P9 EVA-L09 via Telekom Germany.
cause i don't want the Telekom **** on my device i decide to TWRP, Root, and flash P9 stock Rom on it.
Unlocking and install TWRP with the SRK Tool works fine. Install the Root was a bit more tricky, because windows lost the correct ADB connection when i go into TWRP Sideload Mode. Because that does not work, i decide to flash the P9 Stock ROM without Root to come forward.
While flashing, (i don''t now anymore which method i choose to flash) an error appers, and the flash process canceled.
The Device don't boot anymore. After a loot of googeling and testing, i've found out that the problem was the encryption of the /Data Partition.
TWRP was unable to mount it, same for the /cust and one more.
After reading about other Methods to get the Phone work again i try this Method i've found on xda.
http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818
Unfortunately the "press all buttons on the phone" Method don't work.
I also tried out the Huawei Update Extractor to flash single image files to the partitons of the phone. I used the dload file form the previous Method

Download from xda huawei update extractor and extract img files from the update.
Turn off the phone, then press vol- and power key, you are in fastboot mode.
Then, flash img files from extracted rom with:
Fastboot flash system SYSTEM.IMG
fastboot flash boot BOOT.IMG
And do the same with the others...
When you finish, fastboot reboot
Click to expand...
Click to collapse
But that don't work. fastboot already replies with "Remote Command not allowed"
i changed the Method a bit. I've put the BOOT.IMG and RECOVERY.IMG an an SD card and flash it via the Install IMG Funktion of TWRP.
That workes very well and expect the /data partition every partition was mountable again.
Then i used the "Fastboot flash system SYSTEM.IMG" again, and tada it works without errors.
The device is booting again to Android, but it reports that the /Data Partition Decryption failed and i have to enter the Recovery Mode and do a factory reset to unlock the partition. If i reboot for get rid of this error the phone does not boot into the Recovery, it boot to the eRecovery which is useless for that because it only provide the eRecovery function instead of also a normal factory reset (how dump is this )
Now the state is, phone boots normal, reports the /Data is not decryptable, reboot to eRecovery, shutdown or reboot. It does really nothing else.
I can't get into the Fastboot/Download Mode, it ignores the Key Combination Volume down + Power. If i press this it starts normal.
I also can't get into the recovery / TWRP Mode, it ignores the Key Combination Volume Up + Power. If i press this is starts normal.
I've also noticed that the Phone is not conecting to the ADB on my computer, only the virtual CDROM from wich the HiSuite is installable connects.
I've also noticed that the eRecovery is not able to starts WIFI on the phone. It errors with "Starting WIFI failed!"
I also tryed out another time the dload function. This changed nothing. Phone boots still normal and run into the Decryption problem.
And i tried out to boot into fastboot or recovery after a cold reset, battery empty
Now it's on you. Has anybody an idea how i can solve one of the above problems. I think when one is solved the others will disappear via flashing new TWRP or so

Try connecting your phone to usb and then holding power+volume down until it boots to fastboot mode.
Huawei phone won't boot into recovery if system and twrp don't match but it should boot to fastboot allways.
What is the last rom you had on your phone while it was working?

I see two possibilites for this behavior:
1) The phone only pretents to reboot but makes a kind of warm start (never running the code to branch to recovery/boot) -> if the phone seems powered off and you attach usb cable, do you see standard battery laoding animation (that's what it should be) or black screen / boot logo?
2) You flashed a wrong boot.img and/or recovery.img or flashing got screwed up
If you have wrong images, fastboot should still work as edint3000 said.
For the unlikely case (1) with non removable battery you have to wait until battery is drained before you can boot into fastboot after connecting USB cable. Edit: oops just saw you did that.
I had another phone that at some point decided to go only in fastboot with volume down and no power button, when powered up with USB power. But I had never such an issue with a Huawei phone. However, playing around a bit costs nothing (but time).
I see no reason why fast boot should not work. How did you find out, that everything is fine after flahing with TWRP and before flashing system with fastboot?
Did you do anything else than flashing the system.img with fastboot?

Same problem here...Phone not boot/not enter fastboot mode/not enter recovery mode...just stuck "your device booting now" screen...any solution?

Hello Mossyhand
you should search for the recovery Method with an "dload" ROM. This are kind of special Roms wich are able to "selfflash" onto the phone.
You have to put the right file onto your SD Card and then you have to press some keys when i remember right.
Sadly i've forgot, when i solved my problem, to reply how i did that exactly ._.
But if you do search in the dload method you will figure a way out i guess
If you don't find an right file, i can upload you my file, i have it still on my computer

had the same problem
go into the erecovery, it will tell you the data partition has been damaged. u can wipe it from there. go into trwp again, install rom and stuff. voila, works
cheers

H811 stuck in bootloop, No recovery

I had messed up a couple settings on the custom ROM I was running. I wanted to get back the stock setting so I went to recovery and did a wipe. I rebooted and found I lost supersu. I went to reboot back to recovery to flash supersu and It wouldn't boot into recovery. I went to adb on computer and couldn't reboot it there either. I found I could put the phone into Download mode. I tried the flashtool and LGUP and neither will communicate with the phone to be able to flash stock firmware. I don't mind too much because I can JUMP, its just the boot animation says Xperia.
ADB commands only produce "Waiting for device"
Flashtool says, "Wrong dll file"
LGUP won't let me use a current KDZ but only a tot file and the only one I found is 10n.
Relevant thoughts welcome as I continue to scour these pages.
Apparently LGUP considers going from 20r to 20p and upgrade. Lesson learned. 1) When your phone is bricked playing with other tool settings can't hurt anything. 2) Sometimes the OP of a thread can be a little ambiguous, read and reread. If one thing doesn't work, check for (possible) variations.
I was using refurbish setting on LGUP because that's what seemed to apply.

NEM-L21: Stucked with wrong version of boot.img, no more possibility of flashing

Hello everyone, it's my first time writing here, but I’ve tried everything, searched everywhere, and am desperate for help.
I screwed up big time while trying to flash a custom rom on my nem-l21, as I successfully did before with my xiaomi... So what I did:
I managed to unlock bootloader with dc unlocker. Then I got stucked flashing twrp with adb tools. Everything was looking to be fine, no error messages, “flashing successful”… But, I was never able to boot into flashed twrp. Always got stuck on “your phone has been unlocked blah blah. Your device is booting.” It never booted, not in twrp, nor in stock recovery. I tried different versions of twrp from different sources, always same result (flashing successful, booting into recovery not). Booting into the system was fine. And then I made that horrible mistake. Oh, how I wish I didn’t!!
I read on some website, that you are supposed to flash the twrp as boot.img, not as recovery.img. Seemed illogical and stupid to me, but in the end I tried it. Of course, this just bricked my phone, with no possibility to boot. After hours of googling, installing, trying and crying, I managed in the end to flash back stock boot.img. But at that time, I didn’t know my build number (b359), and I flashed boot.img b351. So now I have a phone which boots into the system b359 with boot.img b351, but with lot of errors.
- developer options, security options, display and factory reset option doesn’t work and just crashes. Therefore I am not able to flash the correct boot.img b359 or anything else at all from pc, no way to enable usb debugging and oem unlocking. Adb devices → nothing. I am able to use fastboot (fastboot devices sees the phone), but when try to flash something, I get error “command not allowed”. Also I can’t enable unknown sources installation, which bothers me a lot. And I can’t make factory reset to restore the crashing settings. Also I can’t change display timeout, and original 30 secs is super annoying.
- I am not able to uninstall even apps installed by me, always just restarts system UI and app stays.
What I tried so far:
- flashing correct boot.img from pc, not working because of dev options crashing
- go into recovery, but stock one is overwritten with unfunctioning twrp, always just get stuck on “your phone was unlocked blah blah… your device is booting now”, but it never does, have to hard reboot
- go into huawei erecovery, which is working, but when I try to resolve problem from there, always ends up with errors and crashes
- connect to pc and use HiSuite, system recovery tool here always says “no problem detected”
- updating to b361 through system update settings, always crashes on 5% and sends phone into “your phone was unlocked blah blah… your device is booting now” error
- downloading the proper b359 as and update.app file, put it in dload internal storage → same error during update, put it in dload sdcard → same error, no matter which way I use to start the update
- boot into twrp or stock recovery.img through fastboot without actually flashing it, anyway error “command not allowed”
- do factory reset or update through dial codes (i.e. *#*#123456#*#* …), nothing worked
My pc is windows 10, all drivers up to date. Using powershell as an admin. Am an idiot for not making backup of the phone before I started...
So, now I have more or less functioning phone, but I can’t uninstall any apps at all, can’t install from unknown sources, can’t do nothing from pc, can’t make any update, and lot of important settings keep crashing.
I can use the phone like this, but if somebody could think about some solution for this ****ed up situation I got myself into, I would be grateful to him/her for the rest of my life.
Sorry for a long post.
Thank you in advance and have a nice day

I think using Hisuit will help. Enter Fastboot and connect ur phone to ur computer and use system recovery toll

how to get out from Bootloop

Hi all,
My Lgg8 has bootloop now. It loop betwen LGG8 logo ->Erasing Circle -> LGU+logo (sometime logo stuck in the middle). see below video (pls fast fwd..it's a bit long.):-
Mine is a Korea G820N with LGT. No bootloader unlock, No root. All stock. This happen after I replace the faulty camera module. (even I have removed that module and still the same)
I have install all the tools, LGUP, LGUP cmd, DLL, LG driver, Qil. I can go in download mode, factory reset screen, fastboot menu. all are normal.
I can flash new kdz and I have download a few different kdz to flash, (hv tried LGUP no matter refurbish or update option) have tried LGUP cmd. have tried LG bridge. All 100% work and no issue during the flash. BUT, the phone still the same bootloop as the above video.
Do you think here is a hardware issue in the mainboard rather than software ?
I don't need it unlock or root, I just want to back to function in stock ROM.
Looking forward for your comment.
cheeers,
