Lg G8 AT&T boot_b.bin lost, fastboot loop - LG G8 Questions & Answers

hello my name is petrus and i have a lg g8 LMG820M ATT with unlocked bootloader, i installed a custom rom ArrowOS 12.1 that worked perfectly, however i went to root with qfil and accidentally ended up replacing boot_b.bin by boot_a.bin , now the phone is stuck on fast boot screen
it already starts directly in fastboot and the text "ACTICE A/B slot - _a" no longer appears on the fastboot screen, there was no backup of boot_b.bin so I don't know how to solve it
Is there anything I can do to get it back? Or did he become a piece of garbage?

No, not a piece of garbage lol. Given the tools available for the G8; qfil, the programmers firehose, engineering abl, it's almost impossible to brick the device.
So, lesson learned; always make a backup. It sounds like you copied the boot partition for the slot that had at&t rom on it, to the slot that had ArrowOS on it? If so, sounds like just finding a copy of the ArrowOS boot partition should work?
Which version are you running? Someone may have that boot partition available.

yes that was exactly it, i understand i will never do anything without backup, i was using Arrow-v12.1-alphalm-UNOFFICIAL-20220627
so if someone has lg g8 and is using Arrow v12.1 alpham send boot_b.bin and I copy it using QFIL will my device boot again?

Well, if all that's changed is the boot partition it should boot again. But I checked on tele group and no one responded with it.
You may have to download the rom and see if you can extract the boot partition from it.

II have the same problem, were you able to solve it?

i need help

I'm trying to extract this boot_b.bin from the room that AsItLies said, but I'm not going to lie I don't have much knowledge of how to do this so I still haven't been able to extract this file
It's very difficult to extract one without knowing how to do it but I'm still trying

Okay, think this is what you need. BUT!! I'm not 100% it is... SO! first thing you do is back up the boot image from the slot you want to replace it with this one. That way, if it doesn't work, you can just reflash the one you backed up and you're none the worse.
Second: IF, when flashing this image to the boot partition (loading it in qfil speak), you get a warning message about 'over flow of data' (or something to that effect), immediately stop, do not continue, as that's an indication it will not only not work but make your situation worse. Good luck
sorry, xda not allowing me to attach, follow this gdrive link for file.

Don't use a usb 3.0 port when using qfil. You have to use a usb 2.0 port. Qfil is old software and was not designed for the higher speeds.
This is important whether making a backup of a partition of flashing a partition, either way with 3.x ports the image can get corrupted.

I'd suggest joining the tele group for that rom and asking there if anyone can give you the version of the boot partition you need.

Help! Sensors turned off!

Hello everyone. I was with Android 7 on my ZS570KL and returned to 6 for a tutorial found on the internet and worked, but all the sensors of the device were disabled (screen rotation, gyroscope, approximation, fingerprint [only registers up to 93% and gives error], and all the others). How do I reactivate? I came back to Android 7, formatted the device several times, and nothing solves!
What tutorial and why?
No information = no help

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I do not remember where I found the tutorial and the files, but the process is this:
1. Download http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZS570KL/UL-Z016-WW-4.12.40.1698-user.zip
2. Download https://mega.nz/#!tp9DSQ4b!3wdDLsh3BBtPju8G74xlDjLJ9QywFaoLs1T11mMt3QQ
3. Unzip FlashTools64_20161125.zip
4. Unzip UL-Z016-WW-4.12.40.1698-user.zip and move out files under firmware-update to FlashTools folder
5. Put downgrade.bat, boot.img, recovery.img to FlashTools folder
6. Reboot phone to bootloader and click downgrade.bat
The reason was to swap the conventional root SU through the Magisk. I tried to reinstall 7 just by replacing the original recovery available here in XDA, but the process was not going to restart, so I followed that one to try to return and reinstall everything. It worked, I got back to 6, but I did not know everything. It looks like a computer without the drivers installed.
I'd downgrade again, if it was me, this time I'd install a stock Rom (MM) from ASUS. Then test everything again. If everything is good to go then I'd root and upgrade.
Changing the OS in the middle doesn't help if you have a problem.
Especially if it just builds upon the foundations of the previous OS...
Did you flash a complete N rom or do an update?
The ROMs I try are exactly those of the Asus site. I tried the downgrade again to version 4.12.40.1698 and realized something when I flash in recovery mode. The following error messages appear:
Unmount of /firmware failed: no such volume
Mount: failed to mount /dev/block/bootdevice/by-name/mdtp at /firmware: No such file or directory
Unmount of /firmware failed, no such volume
What is it? How to solve?
I need the original kernel and recovery of the latest firmware released, can anyone make it available?

These recovery images are from nenebear59, thanks to him !
Z016-WW-5.14.44.2212_recovery :
For 2.15GHz CPU
For 2.4GHz CPU
Thank you very much! Now I need the "persist.img" file, of the same rom, can you make it available? I thank you!
I downloaded the source code kernel from the Asus site, and the compressed file has a sensor folder. I downloaded the kernel zip file to my memory card and tried to install via recovery, however the following message appears: E: footer is wrong / E: signature verification failed. How do I get install by recovery or via flash in cmd?
I followed this tutorial (https://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061) and managed to recover the fingerprint reader, but the others are still turned off. I really need the correct file! Somebody help me, please!
I got it! I used the persist.img of the global rom of the Xiaomi Mi Mix and the sensors came back! Apparently it's a universal file that caters to any device. You can close the topic!

HELLO! I'm having a similar issue. 5 times my Zs570kl end up stuck in Asus logo boot screen after being charging all night (with alarming overheating) . I had to wipe the device with factory reset every time to get it working again. Last time, when finally booted up, all sensor were off, and I couldn't make them work no matter how much I try factory reseting again. I think i could try to install the persist.img file you mention, could you help me to find it? Thanks so much in advance for your help.

Come on. To downgrade, you need to download the official rom from the Asus website (version WW-4.12.40.1698 - do not forget to check if your device is 2.15 or 2.4 ghz). Downloaded, need to put the rom inside a micro sd card (can not be internal storage, need to be in sd). In addition, it must be with the original recovery (the version is indifferent), if it is in TWRP it will not work. Once you have done this, you will have access to recovery mode, go to the "install zip from sd card" option, locate the zip file of the rom and install it, and just wait. Having problems, report here.

Hello! To reinstall the sensors is very simple (both work to find out the way, but then it gets simple hahaha). Download the adb files (it is available here in the forum, and inside the folder put the persist.img that I will make available here.) Access the fastboot mode on the device, connect to the computer, and open the command prompt inside the folder. Open the CMD, type the following command line: fastboot flash persist persist.img and press enter. The file will be rewritten and after that the sensors will be reconfigured. Restart the device. Having problems, report here.
Solved!

THANK YOU ANDRE!!! I'm really really happy to tell you that everything worked PERFECTLY. I wasn't sure if I need to unlock the bootloader and flash root first, so I tried to do it. I've been able to unlock the bootloader, but for some reason, when I flash the bootroot.img following the instructions from this post - https://forum.xda-developers.com/ze...v-liftoff-zs570klpro-official-unlock-t3557276 -, I get the asus logo boot loop. Anyway, without the root I flash the persist file and, as you said, all the sensors were reconfigured.
Again, muito muito obrigado!!!

If you want to root, flash the twrp and then supersu zip from twrp

Unable to do the initial fastboot boot "twrp.img" file

Every time I'm trying to run the "fastboot boot twrp-3.2.1-0-taimen.img" command for my Pixel 2 XL (or any twrp .img file for the P2XL for that matter except the alpha version), I am constantly stuck at "downloading 'boot.img' . . ." (attached image #2). Attached image #1 shows that I unlocked my bootloader.
On the computer terminal, the "downloading 'boot.img' . . ." message will stay there until I either start my phone again or restart the bootloader. I am also 100% certain I have been in the correct directory this entire time otherwise I don't think I would have even made it this far. Attached image #3 shows where the twrp.img file is. Line 1 on my terminal also shows that.
I'm at a loss. Any help would be appreciated.

Hmmmm, interesting, dealing with another member on another thread having the same problem you are, except he side loaded 8.1.
I'm hoping one of the RC's or Developers can chime in. I think this is where the A/B partitions cause headaches. Reason being, after your OTA, you now are on partition B. I'm thinking that adb automatically recognizes partition A by default. So when you are trying to fastboot anything, there is essentially no OS to flash to. I think you may have to flash the stock factory image to both partitions to be able to root. Having said all that, I could be way off base, which is why I'm hoping for some help in this matter :good:
Have you tried a different cable yet?

Oh geeze, this is something I can't be bothered with at the moment with my current situation (living and working in Thailand). I appreciate all the input that you have given on this thread though! I think I will just keep my phone where it is at now then (unlocked bootloader, 0 modifications, 8.1.0). But I will continue to follow and see if there are any definitive or streamlined solutions to this potential problem in the (near) future. Adaway and Viper4Android are still very important enough reasons for me to root.
I will also add that when I tried rooting via the magisk method (patch_boot.img), I kept getting a message along the lines of
"target didn't report max-download-size
sending 'boot' (x KB)...
FAILED (remote: Requested download size is more than max allowed)
finished. total time: 0.123s"
Although even though despite always getting a message like this, I was able to somehow get root successfully one time. I decided to unroot and try to duplicate the root result but to no avail. Also got that annoying "internal problem with your device" message and followed @topjohnwu's tutorial only to get the "target didn't report max-download-size...FAILED (remote: Requested download dize is more than max allowed)" message again.
My laptop is currently running Manjaro (based on Arch Linux) but I can't imagine it being the reason I keep getting that "target didin't report max-download-size" message.

Make sure you adb/fastboot is up to date, it has caused many headaches for people trying to use older versions.

I'd say try to get another cable ASAP, especially if anything else you do doesn't work.
When I first was attempting to unlock my bootloader, nothing worked when I was using third-party cables.
Luckily, my laptop had a USB-C port, so I was able to use the stock USB-C cable and I haven't had any problems since.

Kinda what I thought. How did you erase BTW? The interesting thing is that some of their adb commands won't work properly. Explain if you please how you did it so these guys can get back up to speed. Thanks for the input :good:

I'm on my mobile right now so I can't detail it but you would go to Google a site to download the full image. Then run the flashall command to wipe and start from scratch.
I was lucky I had a titanium backup for my apps.. I had to wipe eveything and start fresh.

Hey, I had the exact same problem.
Posted a couple of times on the thread guide for root with magisk, ended with the same answer: fastboot/adb up to date ? Files where they should be ? (they dont need to be on the same folder as fastboot you know..., but they keep asking that...), and so on...
Tonight, latest attempt, instead of using my usb-c port, and my usb-a 3.0 port, I get back on my old laptop with 2.0 usb-a port and... It worked !
Just using 2.0 instead of 3.0 did the job ! You should try it

Dude, if that's the answer, which it probably is, I'm gonna pull my hair out. Been trying everything I can to these folks out. And it's a flippin 8 dollar cable! Oh well, live and learn
I know tou probably did this already but I did not see it posted.
You did enable developer settings and enable oem unlock in developer settings?
Is there a solution to this issue? I have followed every set of directions I can find on XDA and beyond, wiped and wiped, locked and unlocked my phone a few different times. Tried different cables and different ports on my computer. No matter what I do, I am stuck at the "downloading boot" after trying to flash TWRP. Thanks in advance for any help.

adb/twrp issues....

Firstly, when plugging my 7t in to my windows 10 PC, I am asked to choose which mode to go in within usb preferences, as I did previously in order to achieve and ADB driver connection I chose file transfer.......
this didn't work for some reason, only when in MIDI did I get a confirmation with adb devices.....even though there is still no sign of adb interface in device manager.....
any ideas? I can get adb connection with MIDI but is this good enough to flash recoveries/boot images etc....?
I tried to flash twrp and I could successfully boot into twrp directly via fastboot but twrp couldn't seen any of my storage, despite having all security methods turned off...
all i want to do is gain root access but I am having no joy....
ever since android 10 rooting anything for me has been a pain in the ass......truly fed up....it shouldn't be this hard......
I also flashed a patched boot image in an attempt to gain root access but it all did was break my wifi........which i fixed by copying over the latest image and installing locally......

It would seem that TWRP is a no go, for awhile at least.....
anyone managed to gain root access by flashing a patched boot.img?

Lots of people have. Just boot your version and use magisk to direct install and reboot then you have root

This isn't functional at the minute as TWRP, whether its flashed or booted from, cant get past the encryption.......it cant see/mount the internal storage....

You will have to wipe the data and then twrp can access internal storage.
This is how I did (in my phone, which is not Oneplus, but the process remain same for all phones), boot to fastboot mode and type this:
fastboot -w
Now, boot your phone to recovery mode:
(Now take complete twrp backup of your phone, and save it in your pc, before proceeding futher)

TWRP is not functional at the moment, so stay away from it.
The only way to root right now is to use the patch boot image method.

No don't do this.... This is not about encryption at all. It's about the major partitioning changes that has happened in Android 10. Wiping the system will just make everything worse.
Avoid using TWRP at all.

Oh, I didn't know this phone was on Android 10, Thanks for letting me know.
TWRP doesn't support Android 10 yet.
You can see it here
https://twrp.me/site/update/2019/10/23/twrp-and-android-10.html
Actually there is a twrp compiled for this phone, but that doesn't work , you can see the messages in thread:
https://forum.xda-developers.com/oneplus-7t/development/recovery-unofficial-twrp-recovery-t3976961
The steps I told, was for Android 9 and earlier devices, I assumed, this is an old device.
@mediaman123, So please wait, until twrp starts supporting the Android 10.
And for rooting, I am not sure, whether magisk supports this new phone or not.
Maybe @Lossyx can help you on that.

The only boot images available with that post is the 10.0.3...

You can go ahead and just fastboot boot them. If it works then just proceed, if it doesn't, just hold volume up+down and power button. (To boot into fastboot or restart phone)
Nothing will change in the system because it only boots a temporary image.
If your want to extract your own boot image you can use this tool.

So if it boots an older image successfully I can move it over to the phone to patch to then flash it or use the already patched one and flash that...?..

Hi thanks for the link. But my phone is bricked, can't enter recovery or fastboot mode. So the only solution here is a read firmware or scatter file.

Simply... You can't without root.
To get root (permanent root) you must unlock your bootloader........
Please, read this post to understand what i'm talking about https://forum.xda-developers.com/t/nokia-g21-development.4424031/
I think that today there's no way to unlock G10/G20/G21 bootloader. Then, no root or custom recovery can be build.
Maybe, @mvikrant97 can share with us some info (PM).
I unlocked my g20 TA-1343 by taking a hundred tiny screws out , shorting the test point, and using MTK Client 1.6
hyperlink of the link i pastedhttps://github.com/bkerler/mtkclient
I only took it apart because the other option was send it back to HMD
But I don't know how to flash the bin files with magisk or whatever as they're not valid images. but the thing is basically root if i felt like learning.

Question HELP - Realmeflash.exe "cannot find central directory"

Hello everyone !
I am French and my English is very bad so I will use Google translation to communicate with you!
This is what is happening.
Without doing it on purpose, I flashed the original boot with the unofficial TWRP one!
Since then, I can no longer use my phone and I no longer enter the RUI3 interface.
I used Realmeflash.exe to reinstall the firmware and it gives me an error message "cannot find central directory".

I had the same problem you gotta get the MCT OFP extractor tool and QFIL, you extract everything with the MCT tool and then use QFIL to flash but the super.img is broken up into multiple files which I Have no clue how to merge so I'm stuck for now but if I get it working I'll be sure to tell you

I already tried !
According to Google the .exe is infected with a virus, but I used it anyway, because I know it can be a false positive.
During use, the flash does a lot of "Success" but also "Failed", because of data protection on certain files!
Arrived at "service.img", the flash stops and nothing advances!
I recently unbricked my GT ME using this flash tool only. Realme flash tool doesn't support AB partition & dynamic partition table. It is the only working tool to flash through fastboot. After flashing completion change slot
fastboot getvar current-slot
fastboot --set-active=a or b
fastboot reboot

Hi, I got my phone back from this scam repairman!
He damaged my phone even more than I left him!
Could you send me a screenshot of your c:\adb\dir please!
I no longer have recovery mode and the repairman told me a lot of things that I supposedly did during the flashing to get rid of his bull****!!
Thank you.

I already did, I have this command line that appears instead !
When I launch the program for slot A, it's very random when it blocks !
On the image, it's xb1_config_a which bug !
And when I close the window, it gives me success before it disappears !
In general, I have 50% success and 50% failed !
The furthest file that gave me the bug is the "super" file !
Apparently it is cut into 5 parts with the OFP extractor.

Every partition flashes in both slots except super partition. Super partition only flashes in inactive slot, that's why u need to change the slot. Super partition flashing takes around 25 to 30 minutes you need to be patient. & After flashing check slot and change it
urstrulynaveen
Thank you very much for helping me, it motivates me not to give up !
Did you receive a lot of failed during flashing ?
@urstrulynaveen
Problem solved...everything works! !
I'm in the interface and everything seems fine at the moment.
The flashing problem was what you said for the "super" file, but the main problem was above all the fact that I wasn't using a USB port on the motherboard !
Were you able to root the phone ?

It's very easy !
1. You download the latest firmware
2. You put your phone in fastboot mode
3. You connect your phone with the original cable to an available port on your motherboard
4. You open the "OppoRealme-OFP-Flash_1.0.exe"
5. You choose the "most logical" options
The files will install one by one and you may get a lot of errors!
Leave it, the program will continue and at some point there will be a "super" file which will take a long time to install (30 minutes), you wait and then you will see your phone restart as if it were brand new !
