Advice needed, flashing custom ROM - G3 Q&A, Help & Troubleshooting

Hi All,
I have a LG G3 (European d855) that was previously running CyanogenMod 13, a long time ago it refused to install future updates either over the air or flashing, I left it a long time as it was only a secondary phone I used for work.
I have since decided to flash a fresh OS (Lineage and also tried AOSCP) as the only important thing on this phone was my contacts. At first TWRP was giving me an error 7 no matter what ROM I downloaded, I read to change the script in META-INF to bypass the security feature to remove the "Asserts" re-package and try again. So I used the adb push command to add the new packaged file to the device and attempted to flash. I now get a new error "could not find META-INF/com/google/android/update-binary" in the zip file (the binary file was never edited).
Also as a side note I can no longer connect with adb when I had no issues before. The phone currently has no OS and refuses to install any package.
Could I possibly have corrupt partitions?
Any help will be much appreciated

Google apps on Motorola Xoom running cm-10.1-20131007

Last week I brought a Morotola Xoom on ebay, it had 4.0 installed but I wasn't that impressed with it having got used to stock 4.1 on my phone.
I came across the great guide at http://forum.xda-developers.com/showthread.php?t=1477024 and used this along with http://wiki.cyanogenmod.org/w/Install_CM_for_wingray to unlock, root and install cyanogenmod 10.1 on it.
It was mostly a stress free install (although I managed to miss renaming the stock files that the post says causes Stock Recovery to overwrite CWM but it seems to still work OK.
My issue now is that I don't seem to have all the Google apps. It has gmail but not maps or market. I assumed that gmail isn't part of cyanogenmod so the 'gapps-jb-20130812-signed' file has installed (I think that file is the correct version).
It's not too clear from the instructions they read to me that you install the main CM zip and then Google apps without needing to re-boot in between, is this correct? I've tried a completely fresh install and also wiping the cache partition but no luck. But have not tried re-booting after installing the CM then installing Google Apps in a second boot, worth a try I guess.
Am I just making a simple noob error here? Thanks in advance for any advice.
A update, I've just tried formatting and re-installing again, only this time allowing a reboot into android prior to trying to install Google apps. One thing I've learnt is that the gmail app is part of the base install. Installing google apps appears to go ok but upon rebooting they aren't there. My next test is to try yet another clean install and an old version of gapps (gapps-jb-20120719-signed).

Motorola Xoom issues with 'Motorola fast-boot' replacing 'clockwork-recovery'
A further update... It's not gone well, it'd defaulted back to Motorola fast-boot protocol support not clockwork-recovery (after me initially forgetting to rename the files even though it's worked for many re-boots until now).
I've then tried to run back through the guidance at http://forum.xda-developers.com/showthread.php?t=1477024 to re-unlock and re-install clockwork-recovery.
However, it's not gone great, for a start it took me a while to work out to turn on usb debugging in Cyanogenmod 10.1 (see http://wiki.cyanogenmod.org/w/Doc:_developer_options) so adb can see it. After a couple of hours of messing about I've managed to get clockwork-recovery back on it.
However when booted into clockwork-recovery I got a 'error: device not found' from 'adb remount'. So I was not able to rename the files to prevent the Motorola fast-boot overwrite of clockwork-recovery eventually happening. When android is booted and it isn't in recovery I get a 'remount failed: Operation not permitted' response to adb remount. Is there another way to rename '/system/recovery-from-boot.p' and '/system/etc/install-recovery.sh' without having to do it do it at that first boot, it is interesting that clockwork-recovery survived several boots.
I've decided not to risk the install of a potentially unsupported zip of Google apps when my recovery situation isn't solid.
Hmm a fun morning, I've lost times now at how many times I've had to reroot it. I've managed to get the Google play store apk and have tried using that (in addition to installing the gapps zip) it is loading but complaining of no network connection.
With regard to renaming the files ' /system/recovery-from-boot.p' and 'system/etc/install-recovery.sh' I've not managed this, when the tablet reboots into clockwork recordery its connection with adb is dropped. I've also tried doing them in terminal when booted and they don't seem to be there.
There doesn't seem to be anyone else commenting on this so I'll just plod along blindly :silly:

Well, I'm with this problem too. I'm trying to solve this problem by myself, but no success at all. It do FC on google play every time it try to update. Every Google App (besides GMail) is doing FC with this CM build.
I tried to:
- Reinstall google apps
- Install another version (compatible with Android 4.2.2)
- Do the wipes again
- Install google play from an outside source (it doen't come with it).
But no success.
Any ideas?
miraidensetsu sorry for my delay in responding, I'm surprised that no other responses to this tread have been made. An update I've now resorted back to the stable release cm-10.0.0. Given it's nearly a year old I'd hope there'll be a stable release of 4.2 out soon.
Initially I had issues with the stock keyboard crashing all the time. But after searching about this I've installed the Google keyboard app and disabled the stock one.

Need help in Reviving Honor 8 Pro

Hi All,
I have a bit of a "complicated" situation on my hands.
Pre-Story:
I bought an Honor 8 Pro device over a year ago.
My device model, according to my box and my device's back panel back-print is "DUK-AL20", but in my Settings -> About menu it's "DUK-L09".
Pre-Problem:
Anyway, I was stuck with Nought OS for a very long time and want to upgrade OTA but no upgrade was available.
I tried several time to manually install Oreo OS manually with using getdroidtips guides and builds that supposed to match my "about" version (DUK-L09) and my back panel-print version (DUK-AL20) but no lock. Each time I got an error that incompatible version or something similar.
This is happening over several months now.
The-Problem:
A few hours ago, I decides to to erase everything on my device (using TWRP) and install a new stock OS on my device - hoping that it will solve the upgrade issues and problems.
After erasing, I can't find a good guide or info on how to install a new OS either by:
1. Trying to install update.app file throught TWRP -> I get "Updated process ended with ERROR: 1"
2. Trying to use DUK_FullOTA_ROM_flasher.zip file -> I get "Updated process ended with ERROR: 9"
3. I try to extracted update.app to a dload folder in my root device and force-upgrade the device -> I get an failure to update.
4. Furthermore. eRecovery failed to download (or even find) a suitable OS to download.
I'm pretty suck in pretty much everything I do is not working.
I would appreciate any help I could get.
Thank you!!!

Is My Mi MIX 2 Ruined?

Someone was "helping" me root my Mi Mix2. I can't be 100% sure what went wrong, but he managed to get it stuck in Fastboot mode, such that no matter what I do (i.e. any combination of power offs, or simultaneous button presses, or commands from terminal). I suspect he did not understand me when I said Magisk was tool best suited...he may have used some more familiar or standard tool like SuperSU or something to try and root.
Assuming I have sufficiently described my problem, is there anything I can do to get the phone back into a usable state?
Is your bootloader unlocked? If yes try to flash ROM using miflash tool.
I appreciate the response/suggestion.

On your advice I did that, including downloading current (?) version and current(?) version of stock ROM. I received a message to effect that a flash script (.bat) file was missing (or at least not found).
Other threads regarding this error suggest unzipping something (?) twice but I didn't see a file inside the original zip file that could be additionally unzipped, and certainly nothing with a .bat extension.
Can you put here the exact error message and when it exactly occurs? Describe the steps you did to get to that point
Hi aa040371
1- download fastboot rom for your phone and unzip it twice , put folder in C:\ storage http://update.miui.com/updates/v1/fullromdownload.php?d=chiron_global&b=F&r=global&n=
2- Look at the tutorial to use miflashtool https://c.mi.com/thread-1857937-1-1.html

I'm Still Here...
So, after more than a few detours and distractions, I have my phone (Mi Mix 2S, not the plain "2" I originally indicated!) basically back to stock...good frustration-tolerance building exercise.
I am currently in the process of trying to get TWRP to remain after booting to OS. I have researched/read numerous threads on this -- e.g. boot into TWRP, flash TWRP, reboot directly into TWRP again -- but somehow none of them do the trick. Every time I boot into the OS, the Recovery partition gets overwritten and I am back to the stock recovery tool. If I can trust/believe what at least one person has indicated online, this appears to be due to a script in /system/bin, but I can't get at that file to rename or delete it. In fact, I can't even see it in the file system as that area is completely locked down. I know it is there as a Find command executed via ADB shell lists it even though it indicates it is off-limits.
So I turned my attention to loading a rooting app/tool instead hoping that would let me get TWRP to hang around for long term...another excursion in futility. My phone model is M1803D5XA, so according to one more forum thread somewhere, I am supposed to be using SuperSU rather than Magisk? Whatever...it seems impossible: most of the zip files I located don't pass security/file-signing check. The one I found that at least starts to load/install (SR5-SuperSU-v2.82-SR5-20171001224502) works fine right up until it fails while trying to update "sepolicy" files. For some reason I have to sideload SuperSU from TWRP because I am not allowed to push a file even to my SDcard via ADB.
I just don't get why this all has to be so difficult, as in each and every step along the way. I feel like Sisyphus or Job or someone similar...sigh Any thoughts or suggestions still welcome...thanks.

Recovery will get overwritten by dm-verity, you have to flash either magisk or another mod that disables dm-verity, but personally I suggest to use a custom rom if you don't care about miui

Hello...thanks. I definitely don't care about MIUI...in fact the whole exercise I am struggling through is so I can get LineageOS onto my phone. I've probably read 50+ threads/posts on 6-7 different forums regarding unbricking/unlocking/rooting/TWRPing/customROMing my particular phone, but this is the first time I've seen mention of DM-Verity. I'll look into it...not really hopeful, though. But anyway...thanks again.

Nexus 7 (2013) unlocked with custom recovery but with dead usb - how to flash or root at least?

Need help, folks:
my old Nexus7/2013 has dead USB port but long time ago I unlocked boot and flashed teamwin recovery 3.2.1.0
Problem: at this moment it has Marshmallow 6.0.1 (MOB30X) which is NOT rooted...
Is it possible - without adb / without connection to PC since USB port is dead - to flash it with old kitkat 4.4.4 (preferred) , or at least how to root it's current marshmallow 6.0.1?

To root it is very simple, get Magisk, save it into the SDCARD folder, boot TWRP and install it. That's all.
Better yet, fix the damn USB port, it takes only a few minutes, then you can proceed as usual - https://forum.xda-developers.com/t/...r-request-failed.3493322/page-2#post-83468773

First of all, thank you for replying.
Yes I have tried latest Magisk 20.4, it starts and all good until this part:
...
- Checking ramdisk status
! Boot image patched by unsupported programs
! Please restore back to stock boot image
- Unmounting partititions
Update process ended with ERROR.... blah blah blah

Well, it is partially correctly beaching because previously I did have tried rooting with some outdated versions of supersu and magisk too, before I realized they're damn old (it was very late at night)
So, what's your suggestion in this case?
Oh, and for fixing USB port I will do it eventually, no problems here soldering anything, but i'm really not good with prying plastic covers... To cut it short, I already destroyed 2 covers and 1 screen on a nexus 6p and on another similarly held-by-glue-and-spit poorly designed device in the past when I was trying to open them. If it isn't hold together by screws I rather don't do it, at least not until I would really have to. Since this tablet is still working fine and is very useful for reading books or watching videos in bed before sleep, the only hardware-wise inconvenience is using damn wireless charger.
Yes, I am planning to fix USB port (and yes again - by resoldering whatever pins broke out there, and not by swapping entire usb daughter-board) but I want to do it when tablet's battery will start to give up too. That's when I will have no other choice but to open it up... But right now battery still gets 4-5hrs SoT, which is more than enough for me.

I suggest to reflash the boot image. Get mob30x and unpack it completely to access this file:
Restock2\data\razor-mob30x\image-razor-mob30x.zip\boot.img
If the unpacking was done on a PC then transfer the boot.img to N7 via WiFi first.
Next boot TWRP, in the Install function switch to image mode and flash boot.img.
As for N7 disassembly, there is no glue involved, easy.

I didn't realized you're the same person who posted "restock" (your path to img file ticked me off) that I read about in another thread! Thank you very much for making it and sharing it, though I can't use it yet obviously, but I have found in restock thread your mob30x-fix zip, which I have used on my N7 - just FYI it worked great and cleared all the old Goo junk apps when I tried it. Very useful tool. Thank you!
(also: leaving old Google Music app was excellent choice since it is useful for local files; and making skip button active on initial wifi setup screen is really very nice touch! You have no idea how many times I cursed damn Goo devs for greying out this option)
OK, mob30x image downloaded from Goo (terrible - they removed all the previous kitkat and lollipop images!), boot.img extracted and installed, rebooted, installed Magisk 20.4 . All went flawlessly.
So I guess - with your help - I have rooted mob30x without adb
Thank you again!
(root confirmed - i just installed my fav Android Firewall and it was granted superuser access - woo hoo! Now I can block ipv6 connections too)

It seems doable but I have not fully tested it. If you make a mistake you may be finally forced to fix the port ...
This method will not work with Android 5+:
- get razor-ktu84p-factory-2482a7d5.zip and extract boot.img and system.img to /sdcard/
- copy the attached android4-system-flash.zip to /sdcard/
- boot TWRP, do Wipe and flash the boot.img as usual
- in TWRP install android4-system-flash.zip which I estimate would take around 70 minutes
The image needs to be processed on the fly. It was so slow, I gave up and only did a partial flash...
Code:
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system ibs=1 obs=4M skip=40 count=10M
10485760+0 records in
2+1 records out
10485760 bytes (10.0MB) copied, 57.214905 seconds, 179.0KB/s
We need to remove 40 bytes from the beginning of system.img. The existing dd function has a subset of features and a faster option is not available. You could mod the image on PC and flash it much faster with an altered install zip:
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system bs=4M
Cheers!
EDIT
I have noticed a filesystem error with this method but there is another way. PM me if you really need it.

Sorry for replying late. I got no indication of the response. To the problem, I can only suggest getting a different version of SPD or m aking sure your computer system is properly updated. I hope you've already solved the issue!
Maybe you're experiencing, "Problem: msvcr100.dll missing error in Windows whilst running SPD (Factory/Research/Upgrade) Tools" See above for solution.
I've noticed a new ROM for world edition, "M40 Pro(M1A3)_Android 11.0_ROW V1.02_20220525", but not getting any system update options for OTA. People flashing their systems may want the latest firmware!
Thanks to your Magisk file I was able to root my tablet, but when updating to the latest version it goes into bootloop, I have tried updating the original firmware image again, but it also goes into bootloop.
Is there any way to install Magisk modules?
Thanks for your post, it helped me a lot to unlock my tablet.
Edit: My version is the M1A1 firmware V1.03_20210804
Edit 2: Finally, when updating my tablet with the root file that is in the post, it did not allow me to install any Magisk module, the solution is to download version 24.3, and update automatically, without changing to a higher version of Magisk
Glad you worked it out Miny !!! Sorry the warning emails for new posts have been going to a gmail account I no longer use.
Also your hardware maybe different and require it's own unique firmware and boot images. It seems the cracking in similar though.
Some questions:
Do I need to unlock my bootloader in order to be able to get root with magisk?
The tools for unlocking the bootloader uses
Code:
fastboot flashing unlock_bootloader
. My version of fastboot (33.0.3p1-android-tools) doesn't have that command. The included one (0.0.0-09219) does, but I wan't to be careful about running softwar from untrusted sources. Where is that version of fastboot from?
Does any of the steps necessary to get root access delete my data?
Hi there.
I have a m40pro (M1A1) running android 11, do you know if I can install firmware Z3A1 to get android 12? Or will be bricked?
Thanks in advance

To tell you the truth, not sure. Most SoC are impossible or near impossible to brick. They usually allow for an injection or have a read only boot section. Other words you could test. Also research difference in hardware between models, and that may indlicate if something may not work. The kernel/drivers are the improtant aspect.

What I found works, is when using SPD Research Tool, load up the firmware.pac and then go into settings and click "Select All Files" and again to unselect, which leaves the default required items.
Then manually change BOOT to the Magisk img. Then click on all VBMETA types, and UBOOT_LOADER (may not be required though). Then flash.
You should get bootable tablet (no looping). Warning: UserData partition is written over.
I'll share my Magisk image for v1.2

I'm using the same version as you on the same OS. After some research it seems like unlock_bootloader was removed in this commit from 2018. From what I can tell, unlock_critical does something else (unlock_bootloader runs
Code:
fb_queue_download("unlock_message", data, sz); fb_queue_command("flashing unlock_bootloader", "unlocking bootloader");
while unlock_critical runs
Code:
do_oem_command("flashing", "unlock_critical" and doesn't take the signature argument);
)
I'll see if I can compile the older version with the needed command.
What about my other questions?
Issue: Android not starting. I had the infinite restart when plugged in the usb. I tried to reload the installation package (succeeded), but didn't fixed the issue. Battery was not charging yet. When I started the Teclast M40 pro, the logo showed up, but the tablet turned off again.
Solution: I have disassembled the cover, unplugged the 5 pin plug from the battery for half hour and plugged again. When I tried to turn it on, everything was fine.

Wow that's weird Doug. Remember this, if you don't already know, that you can do a cold start by holding down the power button for over 10 seconds, on most devices.
I guess you're running now on rooted tablet !!!

I did the installation package process that the Teclast sent me. The last thing they told me to do was keep trying to install the package (wft?). Well, I just open the tablet, unplugged the battery for a while and after that it worked.
Maybe this resolved 2 things:
1-the battery was not properly connected in the first place, so when I plugged the 5 pin to the board it connected as it should.
2- Maybe there is a "memory" in the board attached to the battery that was bricked (or something like that) when I pulled off the plug, this memory was reseted.
BTW, when the tablet came to life again, the battery was at 87%.
