Im so frustratrated cos i need to reflash new FW on my Zen3Max due to Bootloop issue but the PC wouldnt detect the device .. Tried many troubleshooting
- test my other zen3 using the same cable = ok
- tried Other Cable = Negative
- updated drivers
- check usb port
- the phone is charging (but sometimes wouldnt)
when in Luck it would boot to homescreen but when went off battery o tried to reboot, 90% it goes to BOotloop and would hardly work normally anymore.
FIRMWARE installed NOUGAT 7.1.1 (latest)
Factory reset thru recovery mode should solve your 90% bootloop issue. You will lose all your data though.
Also, your phone should be detected in recovery mode allowing you to upload the stock Rom zip to the internal sdcard and flash stock zips from the sdcard. You might be able to backup your data while in recovery mode too.

Hi,
I'm opening a thread because I just couldn't find any way to unbrick my device. In the past I used the FlashTool2014 to go back to the stock LP KDZ for my device.
I was in the stock rom when I decided to mess with the build.prop and then went back to the stock backup. When I restarted the phone it showed the LG logo, screen went black and never booted android. I could access the stock recovery but the Factory Reset won't work.
Then I decided to go to download mode, it connects and the PC detects it as an MTP device. I open the FlashTool2014 and it detects the device OK. When the LGUserCSTool opens it says the Upgrade stopped due to an error and the device stays on 0% and shows USER B70 in the console. I can press Retry, turn off the phone and reconnect in Download mode but the LGCSTool just wont push the firmware.
I suspected I had a driver issue so I tried using a clean win8 install I have for this purposes without success. I cant flash with the TOT method since the other LG Flash Tool wont detect the device in download mode when connected to the pc. This is really weird.
Any ideas ?
Thanks in advance.
EDIT: Solved with another tot file (almost lost all hope), took me 20+ hours to download it, I'll better make a backup of this files on the cloud. Still having problems with STOCK firmwares but could install TWRP and get CM13 which doesn't give any problems.

Hey guys.
I'm issuing a serious bootloop problem with my D802. I need help.
How things evolved, listen my story.
1- I was using Bliss ROM 6.4 , after a new update my cellular data connection lost. So I back to stock lollipop.
2- I back to D80230c with using LG G2 Stock Firmware (Go Back to Stock) http://forum.xda-developers.com/showthread.php?t=2432476 method. I got a KDZ file and I flash it.
3- Then I used [TOOLS] One Click ROOT+TWRP Recovery for Lollipop Stock Firmware http://forum.xda-developers.com/lg-g2/development-d802/tools-how-to-install-twrp-bump-d80230a-t3072186 to get root and TWRP.
4- Lastly, script broke on somewhere and my g2 stuck at bootloop.
- When I connect the phone to computer with usb cable, I am getting bootloop. [ LG logo keeps appearing in every 2 or 3 seconds. ] and it keep going.
- When I connect the phone to the charger with usb cable, I am still getting bootloop (lg logo thing) 5 or 6 times then I see Firmware update screen. Lastly, phone get stable and it holds firmware update screen as long as it charged.
-When I disconnected the phone from charger and connect to computer, it begin to restarting and bootloop continues.
Most importantly, my phone does not respond, if its not connected to computer or charger. I mean, it should connect to computer or charger with usb cable to respond hardware key commands. ( download mode, recovery mode, or hardware key control mode ) Btw hardware key control mode is korean language)
I tried LG PC Suite resolve update errors , I tried .tot and .dkz method for flashing rom. ( Device goes to bootloop when transferring data begin from computer.) These methods are failed for me. I did not try fastboot mode.
Maybe someone can help mw, I issuing this kind a problem in three years of android user.
Sorry my English :/

Hello guys!
Unfortunately I have managed to full brick my phone which has worked without any issues for more then 3 years.
My story:
1. Phone started to have random restarts, basicaly, when phone lagged little bit - it restarted phone.
2. When I did manual restart, I got into bootloop and could not get out
3. With a heavy heart I did a factory reset. - Problem with random restarts ontinued together with random bootloops.
4. Did maybe 5 more factory resets, nothing happened.
5. Found a tutorial to flash new firmware.I was on 5.0.2 D802 30d so I used same. (PC suite could not find my phone and LG support tool always freezed on SW install)
6. I used LG Flash tool with normal flash. - used *.kdz which I have downloaded via LG support tool - checked size with dl from source from xda and they were same so i used it.)
7. All success, but device keep restarting - i think no bootloop anymore.
8. I did full flash again with LG flash tool so have a clean install and hopefully fix everything.
9. Suddenly mid-install my phone auto-disconnected from laptop and even with Retry attemps I wasnt able to get it running again. Then my phone restarted itself and that was it.
Now I cannot go to recovery mode, I cannot go to Download mode, all I see is black screen (turns some light on little bit underneath but no data visible).
Also when connect to my Windows 10 laptop multiple discs trying to load and trying to format disk. (one of them contains folder image with some files inside).
I dont have root, I dont have any other tools installed on my phone, just a normal user.
I tried to download adb but i dont understand it much, and also it cannot find my device.
Is there any way how to still fix my phone or is it completely lost
If so, I please you for a dummies step-by-step list .
Thank you so much in advance. :crying:
So good news,
I managed to load img back with dd application.
My Download mode together with factory reset is working.
I have tried to flash it with LGUP and even with some accused usb disconnections I probably managed to flash new lollipop to my phone.
Now it is optimalizing apps to load android correctly. Only issue I have is low battery, it always drains it too quickly so it cannot load properly.
Any idea how to charge the battery? Every time I connect phone with usb cable it starts up into boot, possible bootloop (cannot say if it is because of low battery or real bootloop)
Thanks
Dude try to install crdroid 7.1.2 nougat rom of d802 this will fix your battery problem
root it and install TWRP with srktools 2.0
this is best way to root G2 5.0.1 lolipop
you can also use LG One Click Root to obtain root then don't update su binary and install Autorec of you model to get twrp

Good evening! I hope you can help me.
I flashed LineageOS 14.1, but I wanted to go back to EMUI. I made all the wipes and tried to flash different stock firmwares through a forced update (volume buttons + power button), but it never worked. At that point, I read about a guy in this forum who suggested to create a flashable zip with Huawei Update Extractor: I followed the suggestion and tried to flash it with TWRP. No error was given, but when I tried to restart, TWRP told me I had no OS installed. I thought it was strange, so I tried to restart anyway. That's when I got in rescue mode. I can't get into the recovery and I can't use fastboot. What rescue mode shows me is:
RESCUE MODE
Attention!
Please update system again
Update User Guide:
*link*
*android avatar*
Error!
Func NO: 10 (boot image)
Error NO: 2 (load failed!)
Pressing the three buttons, I'm able to force an update. The problem is I can't find a firmware that doesn't get rejected. With Lollipop firmwares, it starts to install, but it fails at 12%. With Marshmallow ones, the installation process doesn't even start.
What can I do to make it work again? I'm very sad because this phone was gifted to me a couple of days ago and I already messed it up. I don't even know how to turn it off.
What can I do to get in fastboot mode? At that point, what should I do to flash the stock firmware? Or maybe do I need to find the first stock firmware ever installed into this phone to make the forced update work?
Please, I need help. Thank you in advance!
P.S. The phone's model is ALE-L21. I live in Italy, so I assume it's a European version.
Did you managed to fix this?

Not yet, but I'm working on it. I found out that the device is recognized by my PC if I follow these steps:
1. Connect the phone to the PC and wait for it to go in rescue mode;
2. Wait until the notification LED stops to blink;
3. Disconnect the USB cable;
4. Press volume - and power button;
5. Reconnect the cable.
At that point, the screen turns black and the phone is recognized as "㌲㔴㜶㤸". I installed the drivers and now it's recognized as "HUAWEI USB COM 1.0". I should be able to reflash the partitions and make my phone work again, but I'm still trying to understand how to do it correctly.
Any help is appreciated!

fastboot detects your device when you plug it into your computer?
I mean, if you run "fastboot devices" it shows your phone?
I've had this same problem but with an P8 Lite 2017, after flashing some ROM that supposedly was the stock one and trying to flash recovery I ended up with my phone bootlooping into rescue mode, I was able to "bypass" this thing rebooting my phone like crazy, seriously like after 20 reboot it finally booted into the damn ROM and I never touched the phone again. Sometimes when the phone ran out of battery and tried to power it on the phone booted into rescue mode and again after some reboots it booted to Android but now I want to install a custom ROM or at the very least root this damn phone so that's why I'm asking you if you have solved this, if you do then probably if I follow the same steps I would be able to fix that screen, hopefully.
If you are able to flash something start with flashing all recoveries your update.app has, maybe that's the problem (at least in my phone it is).

No, it doesn't show anything if I write that command...
I guess mine won't ever boot into the rom because it seems like there's no system installed. I made some researches and found out there are some softwares that let you reflash the partitions IF the phone is recognized as "HUAWEI USB COM 1.0". I'm still trying to figure out how to do it correctly though. I feel like if I do something wrong, then my phone won't probably turn on again.
In your case, you should be able to flash a custom rom without any issue. You just have to be very careful and inform you as much as you can: I don't want your phone to end up like mine?. Anyway, it seems pretty hard to go back to the stock rom, so think about it before you flash a custom rom. Also, make a Nandroid Backup is very important.
History:
I have a samsung tab S6 lite LTE version. The tablet freezed out of nowhere when I was working and restarted but stuck in bootloader. After a while, and after removing the sd card, the tablet functioned properly. The tablet had more 80% of battery charge.
I thought the new update might fix the issue. I installed the update. it restarted and stuck in bootloader again. Power and Volume Down buttons will restart the tab, but it never went past the bootloop.
Left it for 12 hours without charging, and then the tablet went into recovery mode. I wiped the cache and when figuring out the other options in recovery it switched off and did nothing. When connected to a charger, a circle with lighting icon showed up. No combination of buttons worked.
Took it to the service center, and was told the motherboard needs to be replaced. I knew it was a software problem so I came home without replacing the motherboard.
I put the tablet on charge for a while and pressed volume up and down button and connected it to the computer. The tablet went into download mode. I immediately downloaded Odin and stock firmware and tried to flash only the BL file to the tablet. It failed few times, maybe because of faulty cable. I used another working cable and tried to flash the full firmware and the tablet disconnected again from the pc.
But now the tablet showed "an error occured while updating and use smart switch for emergency recovery". Smart switch on pc did not detect the tablet, but Odin did. The device manager detected the device as samsung mobile usb composite device. I used a new usb cable and flashed the stock firmware using Odin. The process was success but the tablet died.
It does nothing when connected to a charger or pc. No display and no buttons worked.
I opened the tablet by removing the display, and disconnected the battery physically. But nothing happened.
I tried several times to connect to pc, and for once it was detected by the pc.
This time I flashed the stock firmware using odin with nand erase and repartition. extracted the pit from csc file and added it to Odin.
The flash was a success but the tablet remains unresponsive. I checked the display to see if I had cracked or damaged it while opening, but it is good.
Now Sometimes, the tablet gets detected by pc as samsung mobile usb composite device and I could even flash the firmware with success. But the tablet displays nothing and is unresponsive.
Can Anybody advice What I can do now?
PS. I used the correct firmware meant for s6 lite LTE version every time I flashed.
Disconnect devices from PC USB port & uninstall official Samsung USB drivers. Reboot & re-install drivers. Connect to another USB port preferably at the rear PC.
Flashed latest Android 10 instead of the latest Android 11 stock firmware (AP *super.img.tar file ONLY) using Odin (I used official Odin3_v3.14.4) with Auto-Reboot, Nand Erase and Re-Partition. Input *.pit file. Flashing process might take 'years' but be patient until it ended & auto boot up successfully. Try another USB port if it failed. Therafter, flash the rest of stock WITHOUT Nand Erase & ONLY Re-Partition, Auto Reboot & F. Reset Time.
Once it successfully got flashed & auto reboot, wait patiently as it might also take a longer time than normal to boot up. Charge the device to optimal. Done!
Optional (Remove Knox Guard)
Connect to the internet. Login to your Google & Samsung account to update everything & reboot upon further updates. Thereafter, boot to Download Mode & flashed AP (Magisk Patched *boot.img, blank *vbmeta.img & patched *vbmeta_samsung.img) + BL (Blank *vbmeta.img) WITHOUT Nand Erase & Re-Partition. After successful boot up, reboot back to Download Mode & ensure there's no 'KG State' on the list before deleting('root delete' not ADB) Knox Guard or app named Payment Service as in Android 10.
Thanks. I will try.

By chance is it going to work for KG:Locked status device? I'm on F62, i bought this (second hand) few days ago from another city. Tapping on build number doesn't give any response, When i try to flash any firmware I'm getting response "All binaries are not allowed to be flashed" I'm pretty much confused what's happening here
