When you tried the EUUS did you follow the flowchart in the second post of this thread? http://forum.xda-developers.com/showthread.php?t=1816560
I just ran a EUUS fine following the flowchart - But had a result similar to yours when I didn't unzip the EXE and fill in the CPUID.txt file.

I'm in the same situation, no way to get the v8 UNL BL, stops at stage 2 (BT's apxflashtool) and "3/4 recovery" with AfterOTA TOOL.
I shall try the EUUS flashing (will delete your internal memory), but now I'm very busy so I renounced..
The EUSS file flashing should help

Couple of ideas to try...
Make sure that when that screen comes up there is not a second window it spawned hiding behind it... For me when it got to that screen I saw another window pop, and it was hidden behind the main, the popup window walks you thru the next steps of setting APX mode, plug in cable, hit ok......
Another thing to try is Right click the PBJ20upgrade.exe and choose "Run as Administrator"
Finally download a new copy... when you unzip it you should end up with Several files and then two folders /Image and /usbpcdriver. The /Image folder has all the img files it needs to install. In the root there is a file called version.cfg that when I view inside it seems to have the info that the program uses to tell what version it is going to install... Hazzard a guess that if that file is missing it might not know what its going to install.

[Q] L3 can't boot on recovery

Aim: Flash CM9 ROM
Friend's L3 E400, bricked his phone and somehow managed to unbrick it and root it. No idea what kind of ROM he had on. It was GB though.
Got it on my hands today, tried to get into recovery by pressing Vol- + Home + Power. Phone got wiped (not exactly factory, but reset) and was asking for Google info as in starting it up for the first time.
So no access to recovery.
Rebooted to bootloader and flashed CWM recovery. Same thing happened, phone reset itself.
Downloaded the LG KDZ flasher, and the Greek Cosmote KDZ file and flashed it.
Tried to boot into recovery, still no luck.
Phone is no longer rooted. Tried to root using the usual script and i'm getting permission errors.
"adb reboot bootloader" : is working fine
"adb reboot recovery" : resetting phone
"adb reboot fastboot" : same as "adb reboot recovery"
If anyone has any tip for me I would be really greatful!
Tried a lot of things without any luck.
Tomorrow I'll have a discussion with my friend and elaborate a bit more on the issue.

1. Reinstal system
- Download latest system for you from http://lg-phone-firmware.com/index.php?id_mod=11
- Install normal by KDZ
2. Root phone
- Download attachment (maybe you should deactive antivirus for 10 minutes)
- Connect phone with USB Debbuging
- Open SuperOneClick
- Check "rageagainsthecage" in progam right side
- Click root
- After installation click "Yes" (root test), "OK" (su promp confirmation), and "Yes" or "Not" (donation)
- You have root
3. Install CWM
- Do that: http://forum.xda-developers.com/showthread.php?t=2405279
- To open CWM boot phone: Vol Up + Home + Power if not work use Link2SD or other app to "run in recovery mode".
4. Press "thanks" and dance for me!
- Regards!

On my LG L3 e400, it's volume down + home + power. And when the phone vibrate, I release the power button. I wait to be in recovery mode to release the others

You should have over 1 MILION likes of that post! Thanks mate, that's works!
I wanna dance for you: *shaking ass*

We managed to root the phone with your way!
We are now at the point where we "install/update" the CWM from ROM manager...

Why does it show that i have 2 recoveries installed?
Clicking any of those 3 buttons gives me an error, that it couldn't connect to the cwm's server...
Being more descriptive:
1. Installed the KDZ.
2. Rooted the phone using SuperOneClick.
3. Installed Terminal Emulator and ROM Manager.
4. Tried to use the ROM Manager and got the "can't connect error"
5. Tried VolDown+Home+Power to boot into Recovery. Phone opens up but factory reset. (Terminal Emulator and ROM Manager not installed anymore, but phone is still rooted)
6. Tried the Terminal Emulator to installed the recovery and at "# dd if=/sdcard/cwmrecovery.img of=/dev/block/mmcblk0p17" i get "Cannot open for read. No such file or directory"
7. Tried to boot into bootloader and fastboot install the recovery zip into the recovery partition.. Seems to have worked fine but when booting into recovery phone factory resets again.
PROBLEM SOLVED BY REPEATING STEP 7!
Managed to get in the recovery after all, and therefore installed the CM9. All good! THANK YOU ALL

last night, I try to edit install script and try to install again and again. i found that /system/etc/permission/platform.xml error because of editing sd card permission
now i can pass a check of SHA1 each file before install but while installing, it's check again and i can't pass in this process
so i think it need a full fresh official rom but there is no RUU for my model, all exit CWM backup is already modified platform.xml

After I uninstall supersu and restart supersu not remove yet. What can I do?

[Q] Bricked - after TWRP restore - unsuccessful

It is the same problem as written here : https://forum.xda-developers.com/p8...awei-p8-lite-2017-pra-lx1-brick-trwp-t3660664
I've followed every steps, but my phone is still bricked.
My build version is (I guess?) PRA-LX1C432B100
I tried several firmware builds to restore on, but when I try to install it (by pushing POWER / VOL - / VOL +) :
- PRA-LX1C530B130 : firmware versions mismatch
- PRA-LX1C33xxxx : can't install, I don't remember error message but surely the same as the above one.
- PRA-LX1C432B128 : "Installing update" at 5% then "Software install failed" with sub message "Get help from http://www.emui.com/emotiondownload?mod=restore"
I followed the rooting method from a french website that was for build PRA-LX1C432B100 but I can't find this firmware anywhere.
Can someone have the link ? Tried with Firmware Finder.. Now i'm downloading from needrom but still don't know if it's for the good build version...
When the phone boots, it displays :
- HW Logo
- Warning about the BL
- HW logo
- blank
- HW logo
- Warning about the BL
- erestore
When trying to download and reboot from erestore, it says "Getting package info failed" and thus, can't download.
----
TWRP
I also tried to flash PRA-LX1C530B130 update.zip, but I get the exact same thing as here : https://forum.xda-developers.com/attachment.php?attachmentid=4008385&d=1484772172

Any way to unbrick this d*mn thing ?
I need help, thank you.

Your phone is locked. Try the unlocking by huawei unlockcode.

Thank you for this fast answer,
though, where do I enter the code(s) ?
I went to https://tools.texby.com/unlock-codes/huawei/ to obtain my code, is that correct ?
I entered fastboot, no devices found with "huawei code writer"
Same with recovery mode and eRecovery :

}

Do this command in fastbootmode by adb:
fastboot oem unlock 1234567...... (your unlock code from Huawei.

Oh okay, but i'm already unlocked.
...
FAILED (remote: already fastboot unlocked)
finished. total time: 0.004s
Click to expand...
Click to collapse

Ok., then flash the stock recovery again and make a factoryreset.

I can't find the stock recovery on internet nor on Firmware Finder. Do you know where I can find PRA-LX1C432B100 ?
I flashed many times on differents build versions those files :
recovery.img
boot.img
system.img
cust.img
Do I need to only flash the stock recovery (if I can find it..) to make everything else work ?
if I have no stock system nor stock boot, will it boot ?
And by "stock" I mean "stock for my device" because I've tried many stock images that end up in erecovery, even after a factory reset in the stock recovery.
-- EDIT --
With the mobile app, it says that the PRA-LX1C432B100 has been removed from the server.

Flash TWRP and see if it starts there.

I was in a similar position today and fixed it by using the USB cable that came with the phone and I plugged it into a different USB port than the one I was using. I did, however, have a different error.

Boot into twrp, then install OOS11 zip.
Some error message may occurred.
Just ignore it, reboot see if it can boot normally.
If not working, install OOS11 zip into both slot.

Change your USB cable and/or USB port. Your phone isn't bricked.

The param preload error occurs when u dont have proper drivers installed bro. Try reinstalling the drivers. Then install driver attached in this message. To install it follow the instructions below.
1. Download the attached file.
2. Extract it to desktop.
3. Connect ur oneplus phone to ur computer via usb cable.
4. Open device manager in a separate window.
5. Hold both volume keys and power key together for a while, when the computer recognises the phone in EDL mode, go to the device manager.
6. There will be an unknown device called QHS bulk.
7. Right Click and select update driver.
8. Select browse my computer for drivers.
9. Select browse and navigate to the extracted folder.
10. Select next and install.
After all the above process has been done, disconnect ur phone, restart the device and plug it again opening the msm tool and connect through EDL mode and flash ur phone. The param processing error will not come.
