[help] [oneplus3] [stuck in boot logo] [softbricked] cannot boot into system [solved]

Hey boss., after flashing open beta 12, the phone started hanging now and then. I tried to contact oneplus forums and they asked me to send the log files. Since they took too long to respond, I went to oneplus service centre. They flashed my phone with old oxygen os and the phone didn't start. It went into bootloop
Then I asked them, they said motherboard is corrupted. I left the place and I requested online customer support from oneplus. They too flshed and concluded the same. Can I know whether flashing/sideloading openbeta created this issue? If so, can you provide me support to avail the warranty on the phone? or recover it via any other method or process?
Please respond as soon as possible. My communication with the world has become limited after this issue. I hope there is some sort of support.
Also note that, the phone can boot into fastboot mode, but bootloader is locked. It can boot into recovery. I tried wiping everything, but the phone is not rebooting.
When I start the phone, it stucks in the boot logo and after a while, the screen becomes blank and a white color notification LED is glowing.
Kindly help me.

i had the same issue last week after updating to 13..and i tried to flash the black theme..it went black..i had nothing....it was like it was bricked... here's how after many failed attempt's..i had to clean out all files including backups.wipe data i had to wipe system i had to clean out all previous files.from TWRP recovery.then i had to download the latest software release then put the zip file in my phone storage not in the download file ..then i had to flash stock recovery.then install the new system..and i made the mistake of trying to use some of my app backups like for one estrong file ..all of them were corrupt.so start fresh.

You might try this unbricking method:
https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/
Though your device isn't hard-bricked, this would reset your device to the absolute factory settings (watch out, your data will be erased) on an older OxygenOS version.
I would recommend the 2nd Method, as it restores all partitions to factory settings.
I might also know where your issue came from:
Though you can flash the Open Beta (or any other ZIP from OnePlus) through the Stock Recovery, OnePlus states that you need to be on an unlocked bootloader for not bricking your device.

It worked, but no network connection or wifi connection!
Is there a way to bring them back?

You might try to unlock your bootloader (There are giudes to do this) and flash a OxygenOS package from oneplus.net through the stock recovery, to ensure the firmware is OK (Do a factory reset from recovery!). I don't know if the Unbrick Tool only restores corrupted partitions or all. It might have installed the wrong system over your previously installed firmware if only corrupted partitions are restored. Keep the bootloader unlocked to be on the safe side (After some time you will be able to just ignore the boot message and you have better access to fastboot and recovery)!
Also, GG to OnePlus for (fake) Motherboard corruption!
About warranty:
Warranty should be ok as long as you won't do hardware modifications (I think).
Bootloader unlocking is definitely safe

No, reflash the OxygenOS package of the same Version that is installed by the Unbrick Tool (If you can still get itfrom oneplus.net) and then check if Network does work. Also, check your IMEI.

I think you might have a corrupted EFS partition. That's y you don't have a working network. Check whether your device show a IMEI under about phone.

EFS doesn't have an effect on WiFi.
That's why I think that it is a firmware issue

I think, I have solved it guys. I'll let you know once completely under control

So, Thank you very much for your support. With this little support from you and my previous Foresightedness helped me restore the phone.
So just in case if any one else faces the same or similar problem, this is the process:
STEP0: If there is any partition corrupted, the device don't boot properly. And, The customer care/ sevice centre guys state it as motherboard problem. Donot Panic. Always take TWRP backup whenever you change your ROM. This Backup helps you to restore whenever you're in trouble. In this particular case, ESF backup is required. So, take a complete backup (everything) in TWRP, it saves your ass.. keep the backup in your PC or any safe Storage (the complete TWRP Folder which is in Internal Memory) before flashing any custom ROM.
Step1: Follow method2 in this guide: https://forums.oneplus.net/threads/g...plus-3.452634/
Step2: if everything is alright, its done. Otherwise, The device boots up with some missing features and details. At this time, you have to unlock the bootloader. See The forum to know how to do it. Basic searching can give you the method.
If you can transfer the TWRP folder from PC to Phone, it's good. But the phone boots itself because of missing firmware. Even Bluetooth couldn;'t be used.
In my particular case, I couldnot copy from PC to mobile or viceversa. So, you cannot copy back your TWRP folder in this situation.
So, Unlock bootloader. Then reboot to system (without doing anything)
Step3: Reboot to bootloader and flash TWRP 3-0.2 version only. otherwise device will be encrypted.
Step4: download Ressurection Remix ROM version : ResurrectionRemix-M-v5.7.4-20161113-PUBLIC-ex-oneplus3 or you can experiment with any other custom ROM but only android 6 (*Marshmallow). Also make sure that you have universal adb drivers. install them if not (search in the forums.)
Step5: goto TWRP recovery, in this, goto wipe option. Drag the swipe to wipe button here. (normal wipe).
Step6: Now, in advanced options, select adb sideload option and select the two wipes in the next menu. Start ADB sideload in the TWRP.
Step7: Now, Start the adb sideloading the custom ROM from your PC. You donot Require Gapps for transferring a file. So donot flash Gapps.
Step8: After the sideload is complete, reboot into system. Now you can transfer files between phone and PC. Now, Copy the Complete TWRP folder into the internal memory. A pop-up asks for merging the folders. Allow the merging, even if you have another TWRP backup there. They don't overlap.
Step9: Now, Boot into TWRP and restore completely. The phone boots up properly, this time. Everything works as expected. every mysterious problem is solved. Now you will get update request if you are on previous version of OOS.
Last but not Least: Please do not use any app recovery tools. they may cause issues while following the above steps
Thank to every XDA member, helping us save the time and money we spend at service center.

Yes, boss. The EFS is corrupted. But, thanks to TWRP, it also has the option to backup EFS, modem. SO, I used my old backup from Jan2017 to restore it back.
But, TO place TWRP back in phone, the original OOS3.1.2, even after reflashing didn't support. I thought for a while and flashed the All loved RR (MM) . THen, it gave me the scope to t/f the folder to internal memory.
Now, I restored the EFS , Modem, sytem with data. and hell yea!! the phone is back to life.
Complete Backup, Atleast once for 3 months saves your ass..

I am glad it helped. That's the power of Xda.

My OP3 is stuck on the boot animation only while booting up Oxygen OS. At first I thought it was bricked but as I proceeded I found out that it isn't and i'm able to boot other OS on it. I've had Resurrection Remix which I had no problems flashing whatsoever. But I'm having this problem with Oxygen OS. Has anyone experienced this? What do I do? Please help.

TWRP recovery not working on Blackview BV9500

Hi everybody,
I try to root my Blackview BV9500 by installing first TWRP recovery. I use fastboot mode on a linux laptop to do that.
I successfully flash the twrp recovery image, but after that, the phone don't boot in recovery anymore.
It try to boot into recovery, but it reboot in normal mode a few second after.
I tried also with the cmd "fastboot boot recovery.img".
When i flash back the original recovery image, it work, i can boot the original recovery without any problem.
Does anyone have the problem?
Some one can help me to find a solution?

I, too, am trying to do this. I have not yet flashed it... I was going to use the fastboot boot command to boot the recovery kernel before permanently flashing it, to make sure it would work, and in my googling I stumbled across this post. Serendipity! [Edit 3: Although, reading your post again, I see you tried that as well and it didn't succeed for you. For me, it simply tells me remote: command not found, so how were you able to even get that to work?]
All that said... I have the BV9500 Pro, specifically for the two-way radio, so I'm going to try to keep that little tidbit of hardware working in the process. I mainly just want to tweak the menus a bit, tweak the quick settings, get root, delete the Google crapps I won't be using...
On to your problem, though, I can't help much but maybe if we post back and forth our successes and failures we might be able to stumble through it together?
First, I assume you already have unlocked your bootloader? [Edit: Honestly, I'm not sure flashing the recovery would be allowed without first unlocking the bootloader]
[Edit 2: Perhaps this thread might be of help. Different model, but often the hardwares used by manufacturers are similar enough that the same steps generally work. ]

Thank you for the link, maybe i need to flash the complete rom with the twrp recovery with spflash tools, and it will work.
I will try and let you know, but i will make a backup of my rom before flashing it!
For your problem with fastboot, maybee it's because you need to install it. You can use the command "sudo apt-get install fastboot" on a terminal window if you are on linux.
If you want to enter the recovery mode, you don't need to use fastboot, you can simply enter it by pressing Volume Up and Power buttons together for a couple of seconds when your phone is off.
When Boot Mode appears release all keys.
To flash recovery with fastboot, you need first to enable the developer mode on your phone (go to "Settings > About phone" and make 7th tap on the build number, the Developer options will be unlocked and available), and unlock the bootloader of course.
here what is the process i made to flash the recovery :
- i use the command "adb devices" to check if the phone is well connected. (response is like "BV9500S320001179 device")
- then i enter in fastboot mode with "adb reboot bootloader" (phone reboot and ask confirmation for fastboot mode)
- check with command "fastboot devices"
- unlock the bootloader with the command "fastboot oem unlock" or "fastboot flashing unlock".
- flash the phone with the twrp recovery with "fastboot flash recovery recovery.img"
- reboot the phone in recovery mode with "fastboot boot recovery.img"
Normally the phone boot in twrp recovery.
Hope that will help you too.

I am too facing this problem. In case you got any solutions please let me know too.

Yup. Already had fastboot installed for the LG G5 this phone replaced, the Galaxy Note 4 the LG replaced, the MyTouch 4G Slide the Galaxy replaced, my wife's old Galaxy S5 I used in the interims... LOL, I've got a working install. No, the "Remote: command not found" was returned from within.... Whether fastboot or adb, I forget now, but I was able to get the file to flash eventually, after reading your first post, but unfortunately the phone would not boot to it (nor Android). I thought I'd bricked it. Twice this happened. Each time, after about 5 minutes, it eventually booted to Android.
I flashed the recovery from the ROM in the link Blackview sent me and was able to boot their recovery just fine, so there's something in the TWRP that my particular phone doesn't like.

Thanks, I keep forgetting which keys to hold for recovery versus bootloader, so I use the adb command to be sure without having to keep a notepad nearby.
Clearly I don't do this as often as I used to.

Now that was something I haven't done since the T-Mobile G1 days. My understanding was that you CAN boot a recovery without flashing it first if you"fastboot boot {image filename}" but that didn't work for me either. I'm also assuming that the filename to flash can be anything because the device stores it to a partition, so it shouldn't have to be specifically "recovery-verified.img".
The recovery you have... Were you ever able to boot to it? If so, would you be willing to share a link to its download source, please?
I've got to run for a prior engagement, I'll check back later.
Thanks!

I guess i find the reason why the modified recovery image won't boot.
I find an interesting information in a post of osm0sis (https://forum.xda-developers.com/showthread.php?t=2073775) were he say : "some newer MediaTek (MTK) devices use special image signing that adds a "BFBF" pre-header signature, so images will unpack/repack but most likely won't boot unless run through their internal signing tool."
After more search, i find an interesting publication (http://www.lieberbiber.de/2015/07/04/mediatek-details-partitions-and-preloader/) witch confirm that.
They say in conclusion of the publication :
"Yes, I can confirm that SignTool is able to add digital signature information to firmware images. Signed images have an additional header “BFBF” and some fluff which SP Flash Tool checks on a secure device. Apparently some manufacturers merely used the default MTK key for signing the images, making them no better off than a typical insecure MTK device."
So we have to find another way to install magisk to root it.

Root 9500/pro
Mine rooted already....you guys can check on 4pda russian forum
Note : do not use the 17.1 version of magisk there because after reboot the device will freeze if you resboot after twrp 1st install...instead flash 17.3+ or 18+ right after first install of twrp...
EDIT : dont mind the russian language in TWRP as you can change it to english once there

you can just download latest firmware and simply backup NVRAM etc with sp flash tool also flash with sp tool, you will have then working twrp with disabled encryption. there are tons of post regarding using sp flash tool on this forum
im using same phone and did these actions on first day and did not have any problem with twrp or magisk

Hi,
I've bought this phone in Pro version. I rooted my phone using needrom.com/download/bv9500pro-bv9500-root/ and adb after unlocking bootloader. Then I failed with errors. Then I used SPFlashTool in root mode with official 2018092919_s32v63c2k_jk_pro.rar rom (I don't find it anymore on the net but 1) I got it on Blackview official forum and 2) I have the file on my own PC) with format+Download and replace recovery with TWRP from Jemmini from 4pda.ru before flashing. OK.
Then I rooted again: format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally.
Beware: TWRP is in Russian language at first boot, so to get it in English, first slide the first slide (allowing writing), then select 'Настройки', then the globe on top, then English, then 'Установитъ Язык'.
Hope this helps.
Then, this is my first rooted phone, so I plan to make a custom rom without Gapps (then maybe without Mediatek Ones and agold too) and remake all functionning with apps from Fdroid. Help needed on a manner of removing a system/vendor app properly. Help needed too to add V4A, as I could see max version supported is Nougat. I announce this here as my first post, but my project will be a full post. If someone want help please ask here or MP me
Note: an update of magisk is out (official 18.1), I installed it and my phone tells me a message that facial recognition was not working anymore then it only boots on TWRP... I reflashed it and my phone boots normally again. Wait and see...
Thanks to Jemmini from 4pda.ru again.

It'd be great to have another rom but I'm facing a problem with battery life. Basically mobile network standby drains 5000mah battery every day i turned off from developer option but still problem is there. I have checked every single post on Google but nobody has solution for this. U guys face this problem too?

New update has been released today. It solves some battery issues, but be very careful.
I installed it, having TWRP and now I'm stuck in TWRP. I've tried to wipe everything but I'm still in TWRP.
I'll try SPFlashTool ... hope it works.

Everything restored & updated.
Using SPFlashTool I flashed all files included in 2018092919_s32v63c2k_jk_pro.rar (including original recovery instead of TWRP).
After that, Android booted and then, using OTA, I updated to latest version.

The latest version is not on the forum. I installed via OTA.
But if you mean the previous firmware, there is one link on the blackview forum: http://bbs.blackview.hk/viewtopic.php?t=480235#p795494
SP Flash tools are well documented here: https://forum.xda-developers.com/showthread.php?t=1982587
And a complete list of blackview bv9500 / bv9500 pro files and instructions (in russian): https://4pda.ru/forum/index.php?showtopic=931296
Hope you find what you are looking for.

@kanadali,
for the moment I'm not facing battery drain because there is not simcard in it at this state of my modifications, sorry.
@Reflected_God,
I think this is the link I used, I use the 2018092919_s32v63c2k_jk_pro.rar rom for base.
For all others who faces big problems like me (facial recognition not working then reboot on twrp only, I could reflash my phone with SPFlashTool, the rom and twrp from Jemmini/4PDA in russian only (others don't work for me). I used Format + Download in root mode on Linux. Then format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally. Do other things. To remove gapps I disabled/force stop it before remove with TWRP. Others apps I can't disable simply remove with TWRP. I test if I encounter bugs but none for the moment. If someone wants to know what I do I've made a LibreOffice Calc sheet log, which evolve when I have time
Hope this helps
Bests Regards

Need Files or a GOOD guide. bv9500 NOT PRO.
If someone could upload the exact files that they used, and the exact same steps, that would be great. Please mention what stock version you have and a link to the image if possible as well. I've followed numerous different guides, with multiple different rom versions, multiple different recovery imgs, used sp flash tool and adb/fastboot multiple times, tried making sure everything was unlocked before each try, have all the necessary drivers, and the closest I get to a functional twrp recovery is a green line that appears at the top of the boot screen before it reboots. Ive tried going to the source, the russian site, but all of the links are 404ed. if not for me, then it would be great to just have this all in one place. Thank you please future hero.
Please include exact program versions (ex SP Flash) as well if not zips of them. I am sorry to be asking so much in one post however I truly didn't know what else to do. And I am typically very good with my google fu xD
I currently have build number BV_BV9500_V1.0_20181026. That seems to matter I believe.

I second the notion.
I have the pro model. I have considered rooting it, but honestly, the phone works well enough as-is without root (for me). However, I'd LOVE to be able to play with different ROMs on this device **AS LONG AS I CAN MAINTAIN THE TWO-WAY UHF TRANSCEIVER FUNCTIONALITY** (i.e. not some "needs-a-network-of-some-kind" "walkie talkie app" like Zello but the real UHF two-way), and I'd LOVE the ability to play with the files associated with the radio to really explore the hardware's capabilities.
Unfortunately, this phone seems more popular in [North]eastern Asia than anywhere else so I don't think we're likely to get much on this forum regarding it unless and until BV become a popular name in the western hemisphere.

2017 LG G4 Stuck in Boot Loop?

I unlocked an H812 (2017 version... serial starts with 702) several months ago and successfully flashed a stock Nougat ROM. Everything was working great until now. This past week, it randomly started shutting down. Yesterday, it got to the point where I could no longer boot into the OS. I think I got to the unlock screen once, and then it shut off. Now it simply boot loops. There is no SD card in the phone. I couldn't figure out how to get into Safe Mode from TWRP, so I did a factory reset. Still boot loop. I then did a factory reset + wiped the internal drive, and then reinstalled Stock N ROM. Still boot looped. Tried reinstalling the ROM again. Still in a boot loop. I know LG G4 has hardware issues. However, I can boot into TWRP just fine, the temperature doesn't look crazy at all, and it can stay in TWRP indefinitely without shutting down.
Something I noticed after wiping the internal drive is that when I'm finished installing N stock, it says it's successful, but when I checked the File Manager to look in the internal SD card, it still shows it as blank (with the exception of a TWRP folder). Is this normal? Isn't the operating system supposed to be installed on this? Why is it telling me that it's finished installing, and yet nothing is there. For fun, I tried booting up, and I'm still in a boot loop. But I assume it's because I have no OS? Or does the internal sd populate with files upon bootup?
I also used used fastboot and flashed the 4 core image (H811 because GPT compatibility said H811). And I also flashed the 4 core TWRP. I tried installing the stock N again, and file manager still shows no files or folders on internal sd except for TWRP folder. Phone still stuck in boot loop (no OS)?
Please, someone help!
I spoke with LG in case it is a motherboard issue, and they said they only replace the 2015 and 2016 model motherboards for free.

However, I can boot into TWRP just fine, the temperature doesn't look crazy at all, and it can stay in TWRP indefinitely without shutting down.
Something I noticed after wiping the internal drive is that when I'm finished installing N stock, it says it's successful, but when I checked the File Manager to look in the internal SD card, it still shows it as blank (with the exception of a TWRP folder). Is this normal? Isn't the operating system supposed to be installed on this? Why is it telling me that it's finished installing, and yet nothing is there. For fun, I tried booting up, and I'm still in a boot loop. But I assume it's because I have no OS? Or does the internal sd populate with files upon bootup?
I also used used fastboot and flashed the 4 core image (H811 because GPT compatibility said H811). And I also flashed the 4 core TWRP. I tried installing the stock N again, and file manager still shows no files or folders on internal sd except for TWRP folder. Phone still stuck in boot loop (no OS)?
Please, someone help!
I spoke with LG in case it is a motherboard issue, and they said they only replace the 2015 and 2016 model motherboards for free.

Refer to FAQ # 5a in the UsU unlock thread.
Did you do a clean flash of the rom? If not, wipe cache, dalvik cache, system and most important, format data, before installing the rom again.
I note you did not mention flashing the appropriate gapps for the rom version you're trying to boot up. Maybe an idea if you didn't.
If all else fails, go to IRC (Support / IRC Channel paragraph in the UsU unlock thread OP) and get help directly from steadfasterX.

Yes, I did a clean flash. wiped cache, dalvik cache, system, and also formatted data (yes, formatted, not just wipe). I did not flash gapps because I flashed a stock Nougat ROM (the same one that has been working for months).
I'm really hoping to know whether it's normal for file manager to be blank and not show the Android, data, folders and all that. I want to know if those folders populate upon a successful bootup, or if they're supposed to be there right after the ROM says it's successfully flashed. That way I can tell if there is an issue with the ROM not installing (which if that is the case, of course I can't boot up).
I have been posting on the UsU thread, but steadfasterX said to flash 4 core boot rom and 4 core TWRP. I did that, but still no boot up. And I *think* there is no boot up because I have no operating system? Again, what is supposed to be in file manager after a ROM flash? I asked steadfasterX but have not gotten an answer.

I know when I've clean flashed a rom in TWRP, I show no files in Internal in the USB connection screen. If you didn't get an error indicating no OS installed, I wouldn't worry about that for now.
Again, refer to FAQ #5a. Did you immediately flash the baseband file after the rom flash? Did you re-install the N modem? etc, etc. You may have to re-install the bootloader stack etc. Go through all the steps.
And again, go to IRC if all else fails.

Here's what I've done now at this point. I tried creating and flashing a 2 core boot image via fastboot, and then flashing the 2 core TWRP. Still bootloop.
I flashed the v29a N modem and UsU kernel for my device (H812), then went to TWRP and flashed stock N ROM again. Still bootloop.
I flashed N stock modem again, then baseband package for my model. Still bootloop.
I'm about to extract my MM modem and flash that.
Beyond that, I don't know what to do. I had zero issues with the UsU method originally and everything went fine and has been fine for the last couple of months since I did it.

Well, roadblock again. I attempted to extract modem from the kdz with SALT in FWUL, and after a while, I get a popup window that says: "This KDZ has an ARB of: arb-detect-error" and then it says "Select partition(s) to EXTRACT:"
Except there are no partitions to select. And my only options are "Deselect All" "Extract" and "Abort." If I try "Extract," I get the error, "No partition selected or abortioned by user."
I did make sure I had the latest version of SALT.

Gave up on salt to extract the kdz and turned to Windows. I didn't know what else to do. I was able to extract the .dz, and then extract the modem_32768.bin file. Transferred it to FWUL, renamed it modem_32768.img, and then typed
Code:
fastboot flash modem modem_32768.img
Rebooted, and still have boot loop.
I'm going to investigate this bootloader stack thing (I don't even know what that is). But again, I really don't understand why this all worked fine for a couple of months.

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.

Bricked LG G8 after flashing ARROW OS & TWRP

Howdy all, hadn't done rooting/etc in a long time as my past several phones didn't have much support for them but got the LG G8 and was excited to possibly root it and also install a custom rom. Went with Arrow OS which seemed to run fine and I decided I wanted to get TWRP as a custom recovery instead of the one that comes with ARROW OS. I flashed it but now it get stuck on fastboot and constantly loops to it (and no longer shows the boot a/b.... which probably isn't a good sign). After leaving it alone for some time, I booted it up and now it gets beyond the the fastboot loop but I can either try to boot it up which only gets me the code red warning or go to download mode. I tried to use LG Bridge and download mode on my phone but the Bridge software doesn't detect the phone.
I realize some of this is probably because of my stupidity and I should've been more careful but anyone got any ideas on what could be done to get the phone back to a stable working state so that it can function again? I know there are some more "difficulties" because of the boot a/b partitions and having to handle that stuff properly. If it isn't possible, that sucks I guess but anyone who wants to chime in - thank you for your help!

Sounds like you might just need to reverse what you did to try to get twrp. If you have the boot partition for Arrow flash that back, if you don't have it should be pretty easy to get it from someone.
If that doesn't work can always use qfil and flash the necessary partitions to get LGUP to work, then flash or crossflash to a kdz and start again with stock.

You're in good company. I went down the same path and have become adept at repeatedly bricking and un-bricking my G8. (LM-G820QM5) I picked up 2 tidbits of info that have been helpful. The first is that my G8 ThinQ will not boot Android when the engineering abl_a.bin has been flashed on to it to enable fastboot. Sure it will fastboot, and go into EDL or download mode, but in order to boot the OS, I have to put the normal abl_a.bin and abl_b.bin back.
The second lesson I learned the hard way is that sometime LGUP fails to flash when the phone is in download mode. I was searching around XDA and came across a very helpful post from starlyn1232. They posted a command line utility that has been successful in un-bricking my G8 when LGUP failed.
I downloaded the appropriate kdz from lg-firmwares.com and the starlyn1232's utility from https://forum.xda-developers.com/t/lgup-flash-utility-based-on-lgup-1-16-cmd-and-lgup-1-17-lgup_common-dll.4112121/

Well thankfully, i still had the original files from the unlocking thread in this forum and I also apparently did make a backup of my files right before I installed TWRP 3.4 or whatever and was able to get my phone working again - which is awesome! Also, what's the best way to back up everything on the phone (or at least the essentials) in case of flashing situations like this? I in the past would just use TWRP to do a backup/restore but since I flashed ARROWOS and it has its own recovery and doesn't seem to have a backup option - asking if any one has a recommendation. Thanks!

I would highly recommend looking at bkerler edl utilities. You can easily find his git page which has the download option for an iso linux boot which has everything installed.
It's a bit involved / complicated figuring out the command line interface, but once done you can backup everything and it will create the xml files needed to reload it.
I would suggest this for everyone but especially for those with sprint or att devices, as there is no kdz available for them.
I've recovered from various issues too many times to count with backups I've made for v40, v35, and now G8 (2 of them).
cheers

Could you pass the tutorial on how to install TWRP?

Does anyone have rawprogram0.xml

So the rawprogram xml will be for ea lun, and it will vary by which rom you're trying to flash, it will also vary by segment starting positions for the partitions. IE, there is no generic version of it.
2nd, you don't need a patch xml, just click cancel or skip for that entry. Note; the rawprogram xml is usually generated when a backup of the binaries is made, and it will be for that specific backup.

Hello there sorry to pop in unannounced I would like to interject briefly and please pardon my ignorance I'm still a noob.
I have a similar issue, but I'm a little bit confused as to what I should do. In my Case i have a SOFT brick.
(G8 ThinQ VERIZON LM-G820UM (Model) ---- G820UM20j (Software)).
I unlocked the bootloader and rooted with magisk successfully, Still running STOCK OS
Then I Flashed TWRP.zip and some version of Magisk.zip with the magisk app, Then I Rebooted to Recovery.
Inside TWRP i Wiped, Format and then I flashed Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip
This process Finished without any errors, however, after I rebooted i now cannot go past the Verizon Logo and it's stuck there.
Fortunately, I have All the Original files backed up (abl_a.bin, abl_b.bin, boot_a.bin, boot_b.bin)
And TWRP also managed to create a Backup beforehand.
I can go easily into EDL mode and i also have the engineering abl_a file on hand.
i can also get to the built-in Stock factory reset / safe mode but I'm unsure if I should use it.
So my question is if i would be correct in loading ALL of the original Files using QFIL, or only the boot_a boot_b files ?
or if i should do something else like getting the firmware in my case?
thank you for your time in advance.

Hello, I Managed to Fix it by loading my backed-up original boot_a.bin and boot_b.bin using QFIL, I have successfully passed that Verizon logo now and should be able to go from here, not that anybody asked, I just thought someone in the future might have some use out of this information here. so if you are from the future and you read this, you are welcome and good luck
