LG G4 H815 No TWRP Access - G4 Q&A, Help & Troubleshooting

Hello members of XDA,
The issue I'm having is pretty rare and found few or non threads about it, so I will try to be the most precise possible.
Yesterday I decided to change the ROM of my LG G4 H815, I was previously on LineageOS, since LineageOS on H815 wasn't developped anymore. So I asked myself why not trying Android Oreo with CypherOS. Before any changes I was with the latest version of LineageOS for H815 and I had TWRP with the version 3.0.2.1. Bootloader was obviously unlocked.
So I starded to download all the required material to switch to CypherOS 5.3.1, while the download I've made a backup of my actual lineageOS installation on my internal storage. Once every thing was downloaded I tried to install CypherOS I had an error 7 in TWRP install box, so I was pretty worried, scouted XDA threads about the error but i was redirected to the solution where you modify the update binary with txt but still didnt worked. I've found a thread talking about updating firmware of the H815 ( https://forum.xda-developers.com/g4/development/v5-8-5-n7-1-2-resurrection-remix-t3704450) While panicking I've done a wipe of everything (dalvik, data,cache and system) .I applied thge firmware update but I also re-read the thread of CypherOS and figured that I needed a newer version of TWRP, installed it so. THen magically CypherOS installed without any issue.
After installing the Gapps (Arm64 8.1 Nano) I rebooted and the first weird thing appears, after seeing the LG screen while the boot I have another screen telling me that the bootloader has been locked and that i should visit g.co/ABH for more information, then CypherOS initialise, CypherOS worked like a charm. So I wanted to go to my TWRP and make a backup in case. I launched ADB and use the command adb reboot recovery, the phone restarted and had the following events : LG logo, warning message about the bootloader, LG logo again and then a black screen. However I was in recovery mode since adb found me with the command fastboot devices. I had no TWRP logo or anything linked to it. Few minutes later, I had the basic recovery mode where you move yourself with the volume buttons and select with power where the functions are pretty limited.
Then I rebooted the phone with adb (fastboot reboot), CypherOS still working perfectly. Thaught that it was the bootloader which back to scratch when he was blocked, I figured out that he was still unlocked, I used the command "fastboot getvar unlocked" through ADB. THen I thaught i had to install back TWRP, tried through the fastboot mode but I had an error
Code:
FAILED (remote: unkown command)
since i tried everything i could even in the basic recovery mode, the only working command in the recovery is "fastboot flash recovery twrp.img" but still does nothing.
I mean it's not that terrible since I can use my phone and i'm about to change phone in 2 months for a Oneplus but i would really like to be able to install magisk on the phone to grant root access and be able to use TWRP on it like I used to. By the way the backup of lineageOS has been deleted while performing unecessary wipes.

It's clearly written on the official website and in the official TWRP support thread for the g4 what you have to do when on Nougat bootloader and want to flash TWRP... and keeping it.

Yet, this still doesnt help me to solve my issue. Do you think there is a way to fix it or no ? If not, I'll just deal with it for the few months lasting.

Okay if it doesn't work for you you must do something wrong. It works 100%. If you really want help you should explain in detail exactly which steps you took as otherwise it's all just guessing what you're doing.

Indeed, I didn't followed the procedure exactly, didn't do the step after flashing TWRP (removing battery and boot manually to recovery). Well thank you, was my bad on that.
Should I do a clean new install of cypheros or should I keep it like that, what would be your advice ? Knowing that at the moment CypherOS works like a charm. I also plan to install Magisk on it to root it.

V500 secure booting error

Hi guys,
For now I'm stuck on this error on updating to LineageOS (official repo). "secure booting error" me checked!
I used to do a clean Install nothing more than this. Only if things will load I flash GAPPS etc.*
Previously I've successfully flashed cm13 and cm14.1 and so on.
But sometimes I got the "secure booting error"
When flashing (custom) kernels I always get the "secure booting error".
On flashing roms sometimes it does sometimes it won't.
I'm not sure when or what went wrong or not.
I've never had issues to access twrp or flash twrp. Like I see on most topics.
So I'm pretty sure the problem exist in my bootloader.and not in the roms or other flashing. Maybe it isn't fully unlocked?
My LG G Pad 8.3 (v500) bought in The Netherlands.
I flashed V50020F Bootloader: https://www.androidfilehost.com/?fid=24352994023707804.
Flashing all went fine as far as tarp gives the right info. I only don't know how to check this.
TWRP: 3.0.x
Is there guide de to fix this? I've really spend days on this without any solution. It's really frustrated!
Hmm.. Same issue here.
Was on stable CM 14.1 & TWRP 3.0.2.0.
Flashed TWRP 3.0.2.2
Flashed Lineage experimental 14.1 & supersu addon zip
Rebooted and am stuck with the same secure boot error. I don't understand why I can't get into the same TWRP recovery I was just in to attempt to clean flash a nightly LineageOS 14.1.

Don't use supersu with cm/lineage.
The secure boot error can be fixed by flashing this zip in recovery.

Thanks. Ya I had no idea there was a set of flashable su's for LineageOS in Extra.
Got it working. The issue was mostly that I had no idea how to use the hardware buttons for this tablet to get into recovery.
Thanks that helped me out!!
My Problem:
Lineageos 14.1 and Magisk 17.1 installed, updated Lineageos to actual nightly and got a
Secure booting error, Cause : boot certification verify
Solved with:
Boot into recovery mode with TWRP installed

Fixed it. Great job
[V500] "Secure Booting Error..." solution howto
Let me recap here, 'cause I get trapped in this issue every other year and it takes me a while to retrace back the steps for the solution.
Some intro, for starters: I have been running Lineage OS on my device for years and, at first, whenever I had this, I had to get the LG Mobile Tool plus the full factory ROM to do a KDZ restore -- i.e., start everything from scratch.
There's zero need to do that -- if you had a working TWRP recovery and Android system before, both will still be fully functional after you overcome this problem!
First: you have to get back into TWRP.
This is the hardest part because not only the key press sequence is rather uncommon, you have very little time to get through it, too.
In short, you have to press VOL DOWN + POWER keys until you get the LG logo.
Then you have to quickly release and press all three keys (VOL DOWN + VOL UP + POWER), before the "Secure Boot" error message comes up.
Second: What comes up doesn't make a lot of sense, too: you're dropped in the "Factory Reset" screen.
You'll have to press POWER twice to confirm -- never mind the dire warnings -- to get back into TWRP.
Try again if you don't succeed or check the YouTube video pointed above by HerrRuin good to see how it's done.
Third: once in TWRP, it gets easy.
Download the bumped bootloader from AndroidFileHost, also pointed by HerrRuin above.
(FTR, file name is 'v500-loki-kernel-to-bumped-kernel-signed.zip'; MD5 is 'f1a25de31559462d8c5d4c35d23f84d9')
While still in TWRP, connect the tablet to your computer and transfer the file over.
After the file is copied, flash it via the "INSTALL" button, reboot, and "Bob is your uncle"... :laugh:​
Many thanks to everyone who contributed to this solution that allows me to keep enjoying my G Pad after so many years.

Swift won't boot into system - straight back to bootloader fastboot mode

I'm trying to be helpful to someone and failing . I've not seen this issue before.
I have a WileyFox Swift that has been unlocked and has TWRP as custom recovery. Internal storage has an installation zip in it so looks like an attempt has been made to flash it. Can't Restore, not sure if a Backup was done. When powered-on it jumps straight to bootloader - fastboot mode. (Start/Power off/Recovery mode/Restart bootloader). Options all work as expected except Start which goes back to bootloader. I can also connect to the handset via usb and receive a response to 'fastboot devices' and other commands.
From TWRP I have installed Lineage nightly rom and the installation has completed successfully. Same for Gapps but the reboot option jumps straight back to bootloader (no sign of a system splash screen). A 'Fastboot continue' command at this point causes a flickering recovery splash screen and then back into bootloader again. I've been in bootloops before but usually a step further on than this. Anybody seen this before - am I missing something obvious?
Hi
Method 1
-if u want to install lineage os
install lineage and reboot it without installing gapps after that install gapps . Hope it works
Method 2
- if method 1 doesn't work for you you need to download and install stock rom for wileyfox swift by adb (fastboot)
See ya
Thanks for the reply. The problem with finding a stock rom is that the Swift shipped with Cyanogen OS 12 (not CyanogenMod). Cyanogen is no more and all links to their website have gone so it's hard to track them down.
I removed the battery from my Swift earlier today and forgot about it for about one hour- I think this has made the difference as I flashed a CyanogenMod 14 rom, rebooted to system and it worked :good:. Went back and flashed Gapps and it worked again :good:. I have an older OS than I want but am fine for the moment.
Good for you

G4 only boots to TWRP

I recently dug out my old G4 to see if I can repurpose it for anything or just have it as a back up.
It's an H815 European variant with unlocked bootloader. When I last used it I had it running a custom ROM but when I got a new phone I wiped it somehow with TWRP (this is a few years ago so I can't remember).
Now whenever I turn it on, it boots into TWRP. If from TWRP I choose reboot to system, it boots to TWRP.
I tried to install a ROM but it wouldn't, giving the error "this ROM is for P1,G4,H815 (or something like that), your device is .".
So, I edited the ROM metadata and took out the device requirements and it installed fine, as did GAPPs & SuperSU, but still it only boots to TWRP. I've flashed bootloaders, kernels, god knows what else, but it only boots to TWRP. That's it.
I also tried to return it to stock using these: https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848 but it had errors connecting to servers and never installed anything.
I'm aware that I won't be able to recover anything on the device and that's fine! I just want to boot it with ANY ROM, and I'd be grateful for any help! Thanks!

[Solved]Requesting Help Regarding Mi A2 Lite (Stuck in Unlocked Boot loop, No OS installed)

Just this day, November 23, 2021, I have been trying to flash a custom rom named Syberia OS for daisy(Mi A2 Lite variant). As I have done booting up the device to fastboot(thru cmd command since my power button is jammed), I installed the twrp after booting the image to the device, making it as my recovery.
Now I am set and excited to install the rom, so I went to fastboot again and tried to flash the rom, but it always errors and not installing the rom. It is said "to flash multiple zips, reboot recovery before..." (correct me if I'm wrong), so I rebooted to recovery thru the twrp (since its in fastboot). Now, I did the same, I installed the rom again and experienced the same error so I dont know what to do, I did wiped system, data, dalvik and internal storage (a lot of times and tried to install the rom again), but I get the same error.
Then since I cant install the rom, I went to reboot to system thru twrp, and then I forgot, that I have no OS installed.
So now I'm stuck with the "Your device software can't be checked for corruption. Please lock the bootloader. Please visit this link..." plus arriving to the AndroidOne logo, and it turns off and turns on again with the message and logo, repeats until the battery is completely empty.
Is there anything I could do to go to fastboot again for a clean install of the stock rom? (I promise to not unlock the bootloader and experiment on custom roms again)
(I am sorry if you find it hard to understand, I am willing to edit this thread for better understanding if there are things you dont understand.)

Hey brother, I had the same situation a few months ago. My device - Redmi 6 (Cereus).
So, I was trying to install TWRP in Redmi 6 and then after trying many times TWRP successfully got installed. But when I tried to boot the device, It stuck in bootloop (Going to fastboot and again booting...). So, the answer is that you first boot into fastboot mode of your device and then download the fastboot Rom of your device, (link of fastboot rom of your device - https://xiaomifirmware.com/download/18010/ ) . Then go to your PC and then extrac
the fastboot file, then connect your phone to pc and go to fastboot mode then open the extracted folder and then click on flash-all (The batch file) and then a new command window will open automatically and flashing process will start. After it's done your phone will reboot automatically. For reference, go ahead. Best of luck!

Moto G7 Power xt1955-4 and TWRP 3.5.2_10-0-ocean problem.

Hi, I have Moto G7 Power xt1955-4 with Android 10 Q, unlocked for any GSM carrier, used on T-Mobile network. I unlocked the bootloader and i'm trying to install TWRP recovery image into it. Mostly I follow this guide https://www.androidinfotech.com/root-moto-g7-power-ocean-android-10 . I got the latest available for my phone TWRP -3.5.2-10-ocean from https://dl.twrp.me/ocean/twrp-3.5.2_10-0-ocean.img.html, switched my phone into fastboot mode so it's visible to 'fastboot devices" command, then i run "fastboot boot twrp-3.5.2_10-0-ocean.img" Phone reboots to temporary TWRP now, shows "Enter password for User [0] - ... Data successfully decrypted".
Now, when I try to permanently install TWRP, I got a problem, even though everything looks ok, no error messages: first I installed Disable_Dm-Verity_ForceEncrypt.zip file, with Success. Then I installed twrp-installer-3.5.2_10-0-ocean.zip via TWRP itself: it shows "######## TWRP installer for A/B devices ######## Running image patcher on boot_a... Running image patcher on boot_b... Image patcher complete! Done installing TWRP ***Note: You are now unrooted!*** Updating partition details... Success!" - note no errors here.
BUT when I reboot into recovery mode again, I see only TWRP logo, then phone beeps for 1 sec, and nothing happens after that, no menu shows up, no prompt to "Enter password for user" as before. No response from screen touches. Only reboot helps.
So I understand that TWRP was not installed correctly. What did I do wrong?
Any suggestions will be appreciated.
You should join and follow the G7P (Ocean) telegram group if you haven't already done so. Any questions can be asked there or are already answered in the #notes section. As far as twrp goes because the device is a/b type I never install the zip. I connect to pc and fast boot twrp image to flash ROMs.

Thank you Skippy12359, I found just "Moto G7 Power Ocean/River Channel" on Telegram, with 10 subscribers - is it the one you mentioned?
My goal is to install Magisk-v23 on my phone, to complete rooting procedure. I was going to use TWRP for this, and install it via zip file. But if I use temporary TWRP and just install Magisk-v23.0_renamed_apk.zip, after reboot Magisk app shows "Installed" status as N/A! Apparently it doesn't work as intended... So I thought that permanently installed TWRP would give better result.
UPD: Also I see "Moto G⁷ Power | Builds™" channel with 445 subscribers, and "Moto G⁷ Power | Discussion™" with 379 members. Signed up for those!
There's a Moto g7 power discussion group and a Moto g7 power builds group. If you're new to flashing ROMs put all your ROMs, magisk, gapp files on your sdcard. Then fastboot twrp and flash ROMs, magisk from there. You can install the twrp zip if you want just found it easier not to because it gets overwritten anyway because the device has no separate partition for recovery like an A- only has for example.
Actually this method (fastboot to temporary TWRP, then install magisk.zip file from sd card) works! I was able to install Magisk this way, and first time it boots normally, Magisk shows Install status v23, CheckRoot app shows that everything is ok. But on second reboot i'm getting into bootloop After Warning message and 5 sec wait my phone beeps and reboots.
Magisk has an uninstall zip file if you have boot problems. Once magisk is uninstalled from recovery it should boot up fine. There is also a magisk canary version on github which should fix any boot issues after flashing. You need both the magisk zip and the magisk app installed to have full root
I try Magisk-Canary (after uninstalling Magisk v23 by renaming zip file to uninstall.zip and run it via TWRP) from https://github.com/topjohnwu/Magisk, the result is the same- first boot is Ok, Magisk app shows that it's installed (Magisk status 5d6d2417 (23015) version installed), but second boot gives me bootloop...
What ROM are you using?
I use Original stock ROM, that comes with the phone. XT1955-4_OCEAN_RETEU_10_QPOS30.52-29-7-6_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip file from ttps://mirrors.lolinet.com/firmware/moto/ocean/official/RETEU ( i just found it to get boot.img and patch it with Magisk, I didn't change original firmware , just unlocked bootloader.
I haven't used stock for over a year and I don't recall having any problems rooting or ever had a boot loop on rooted stock Q. Also I've never needed to patch a boot image to get root. I just reflashed stock firmware, installed all the apps I wanted and fast boot to recovery. Flash copy partitions zip and then flash Magisk. After reboot to system I install Magisk app and I'm done. Always worked for me. Rooted and no reboots.
I assume that you have Moto xt1955-4, correct? Which ROM you have installed then? At the time of Magisk installation , was it custom ROM or original stock ROM on your phone?
I have the usa model of the same phone xt1955-5 and have always had it rooted whatever custom ROM or stock firmware used at the time. I'm currently on AICP 11 official custom ROM but switch frequently from Arrow, Colt and other ROMs.

Hey Skippy, When I originally got the phone, I bought it outright from Cricket. A Supra, but still the same as G7 Power.. No payments. No years agreements. Now that it is no longer supported, I want to unlock the bootloader and install a custom rom. Setup ADB and went to Motorola's website for the unlock code. I get "Does not qualify for unlocking." For the above two reasons, I'm a bit miffed. Has anyone found a work-a-round for this? I got up at 6 AM. All day studying and learning how to do this. Only to get the message. "No you can't. Sorry. Notta". And with Motorola's piss poor support policy, it grinds my gears.

I have the TMobile variant codenamed Ocean, so I'm not going to be much help on your question. I suggest you ask in the Moto g7 power discussion group on telegram. I'm sure someone there can let you know if the cricket variant is unlockable or not. Good luck

Thanks for the quick response! I don't use Telegram, but I guess I better get signed up. I wish there was a repository of, an HCL of sorts, where people can refer to before buying phones to avoid these issues.
