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

Hello I have same problem... Do you have that original recovery file? I don't have and I would like to get that back. Thanks.

DL this:

- Copy Magisk-v18.0.zip and disable_encryption_9500.zip to external SD-Card or OTG device
- backup your data from internal SD-Card
- do a factory reset and turn off phone without entering the setup guide after reboot, or wipe via recovery and power off
- Flash recovery.img using scatter.txt with SP Flash Tool
- boot into recovery with hold down vol + and power
- switch TWRP to your language and install Magisk-v18.0.zip and disable_encryption.zip

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.

Is it Brick or is there Hope ?

Hi Everyone,
I would gladly accept any help that is being offered. Thanks in Advance.
So I am not new to flashing my phones but Xiaomi has been one of the most frustrating experiences that I've ever had. So I flashed my phone with the Pixel Experience Rom but I wasn't getting 4G with it and I couldn't recall if I was getting 4G with the original MUI so i decided to flash MUI firmware .
So, Not really sure what I did wrong because i believe I could flash the firmware without any problems but guess not. So it flashed successfully and my phone rebooted into Fastboot and will not load into the phone. So booted into recovery and Red Wolf TWRP is asking for the encryption password which I normally enter and I do it again and behold it's telling me that the password is wrong which is am sure it isn't.
So I am unable to use Red Wolf TWRP to flash anything since i can't mount the storage section because of the encryption and tried flashing the phone with MiFlash but doesn't seem to work. It is telling me that the image and device is a mismatch which I don't believe since I've flashed those ROMS before.
So any helpful advice would be appreciated.

I guess you need to flash stock firmware in fastboot mode. Download fastboot rom from mi website. Power on your phone while pressing volume down keep pressing power button for some seconds to enter fastboot mode. Connect it with your pc and upon connection you will heard plugin sound from pc. Extract downloaded fastboot image and double click on flashall. Wait for process to complete. Your device will auto reboot upon completion

So just format storage, it will be no longer encrypted. Then mount storage in twrp, paste your rom of choice from pc and flash it. Unless im missing something here

A mismatch you say? hmm I have had this before and I managed to flash the rom without issues deleting some lines in a rom package. It's quite simple, just follow this little tutorial: http://en.miui.com/thread-178314-1-1.html

Thanks for the responses. I followed this guide here to resolve the issue.

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.

this will be my last onepluse thatr for sure going back to Pixel 4 XL didnt have no issues going back to stock this is crazy

I'm having the same issue, so I'm gonna piggyback this in hopes of a different direction.. Long story, short, I've spent hours trying to get back to OOS from crdroid 11. the link above got me back to booting up t-mobile and relocks the bootloader, but wifi radio doesnt work & restarting brings me to being stuck on the boot logo. none of the other MSMtools work, unlocked or TMO from the unbrick page.
what step am i missing after going through the tmo to int. guide? since that's the only thing that's working.. thanks in advance, i'm attempting round 2 in the meantime.

When u r stuck on pink TMobile screen, force reboot to bootloader by holding vol+, vol-, & power buttons for 10 sec. Once you see phone rebooting, let go of power button only to enter bootloader mode. Then type "fastboot reboot fastboot" on PC while USBC cable is plugged into phone. This will kick phone into fastbootD mode. Then fastboot flash all stock rom files.
When wifi and 4g not working, u did not enter fastbootD mode, so system did not flash right

this would not work for me im assuming bc i have the global HD1905 not the T Mobile branded. u can read above why it wouldn't work . but i seem to have made some progress using the All in One Tool i clicked on flash factory image tab and at first it keep error out saying no Flash-All.bat found after unzipping it. so i kelp looking around and finally foud a factory zip that had the Flash-All.bat file in it so tried again using the Allin One Tool clicked Flash Factory image and it unzipped it and flashed fine but now i cant boot to the OOS it just reboots to the " your bootloader is unlocked integrity screen and stays . but i can boot in fastboot mode and recovery which is now factory recovery. i noticed that it flashed the OOS zip on slot A so i think the reason its not booting up to OOS is bc i need it flased on both slots ??

using the " All in One Tool "
Flashing is not allowed for Critical Partitions
is this normal error when flashing back to stock OOS ? when the flashing starts it says this for the first 4 or 5 flashing parts then it stats flashing as described in OP. then it reboots out of fastboot and boots to stock recovery then it finishes the flashing . then at the end it says to press any key to continue and the phone reboots and hangs at the screen that lets me know the bootloader is unlock screen. i flashed both a \b partitions and still does the same thing. its like the boot image is not flashing or im missing something else in the OP to get back to stock OOS.
anyone can help me please ?

ok that command worked it successfully Flashed all partitions and when it it it finished it said to press any key to continue .... i did and it rebooted into stock recovery and finished the flashing . then it reboots to the Your Bootloader is unlocked warning and stays there . so i went into recovery and factory reset everything and still hangs at the bootloder unlocked warningthat was all on Slot b so i was like maybe i need to flash both Slots so i switched to slot a active and repeated the whole process above and still nothing hangs again at the bootloader is unlocked warning... ggggrrrrr
what gives..... this is all done using the All in One Tool ... i know im getting close to getting it back to Stock OOS as i made progress with your help.
i then downloaded the factory image from OnePlus site but that was a no go as the zip had only something called Payload which wouldn't flash ..
anymore knowledge u might can share and thank you very much for your help

Go back to fastbootD and flash-all parts manually on A slot, then go to bootloader, type "fastboot set_active other" to go into B slot and repeat fastbootD flashing all parts again. Then go into stock recovery to format data and then reboot

again thank you.

[SOLVED] boot loop after i tried to fix broken root

I tried for like 3 hours to find a boot.img and i had root on my phone, but without wifi and sound.
a quick google search showed me that it was because i had a wrong version of the boot.img, afterwards i found another one and now after i have tried installing twrp, booting and flashing using adb (stock and modified versions of boot.img) but it just keeps bootlooping. in twrp i cant wipe, make a backup, see any files in /storage/ and i have no clue what to do next.

What model 7T do you have? HD1907? What was the rom that you were using before you installed TWRP on? OOS12 does not support TWRP. Custom rom A13 does not support TWRP. Only a few custom rom A12 and OOS11 support TWRP.

Idk but I'm just wondering if flashing the last working rom image (dirty flash)? That would eliminate TWRP(?) and eliminate Magisk(?) while hopefully keeping the device from being wiped possibly?
*** Hopefully someone could/would verify this before you attempt... ***

i was on android 11 but i cant remember the version, i have HD1903 (EU ver). i THINK i had the one from the oneplus website(https://service.oneplus.com/us/search/search-detail?id=2096229) but idk anymore

I JUST RANDOMLY TRIED BOOTING MY PHONE AGAIN AND IT WORKED imma check if everything works and will regardless still look at this thread bc it can prob break easily
nah wifi and sound still dont work, but im not in bootloop anymore

i cant find the file for my current version and it doesnt work if i try it with the only version that is android 11

and i cant turn my phone back on
and after i installed the drivers i had to restart my pc and now there is this thing at the bottom right:
testmode
windows 10 pro
...

i waited until my phone had no more battery charge and now im bootlooping again :/

nvm it just booted

im downgrading it now and i dont get the error "smth communication smth" in msmtool anymore
alr it worked my phone is wiped again but i can turn on wifi and sound
but how do i root my phone now? I have an Idea, im gonna write step by step what i think gets me a rooted phone please confirm if that would not break my phone ^^' (bootloader already unlocked)
1. enable usb debugging and allow my pc
2. download and install the latest magisk version from the github
3. download magisk patched boot.img for ver 11.0.5.1BA BUT since i cant find anything on the internet im gonna have to use the zip file from the unbrick tool thing (https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_7T/EU_HD65BA/R/) and then patch the boot.img using magisk myself
4. then use platform tools and type following commands: "adb reboot fastboot", "fastboot flash boot {the patched boot image file}"
5. then use magisk to direct install the root thing

i just realisized the unbrick thing that i wanted to use instead of a boot.img doesnt have a boot.img in it... WHERE CAN I FIND A BOOT.IMG brooo androidfilehost.com doesnt have it the unbrick tool doesnt have it
omg i realized i could update my phone to 11.0.9.1 then download the same version from official website and use the dumper to get the boot.img **** meee

wait it sais its 11.0.9.1HD65 AA and not BA **** me

k nvm i just changed the site settings to germany and now its BA

i just went for it and now my phone is rooted thank you very much for your help i would've prob tried to revert back to stock for like 2 weeks and then cry that i cant root my phone thank you so much xd
