Hello everyone,
Today showed up on my Gpad an update that automatically started to download.
So I thought ''if it is downloading, why don't I give it a try?''
Big mistake.
I am rooted with TWRP 2.7.0.0 and stock 4.4.2 rom..
My Gpad after I press confirm it tried to reboot. After the device shut down and try to power on, it stuck in a bootloop on TWRP.
Every time I try to power it off and then power it back on it starts on TWRP and stay there even if I press reboot on TWRP it does the same loop.
After this idiotic move of mine I would like to have help from someone who knows how to restore the device..
Also is there any way to restore the device in TWRP or to do the update manually from the file that is already downloaded in my device
(from TWRP)?
Any help would be very very appreciated!

Did you not make a back up after rooting your tablet? If so, simply restore from your backup.
generally, it is advised that before you update a rooted device's ROM, to create a nandroid backup first, just to be sure. As OTA's from non-OEM's aren't as stable as OEM's, nor do they provide warranty if you get stuck in a boot loop. To fix the issue, download your ROM image to the "root" of your microSD, go to recovery, wipe cache/dalvik cache, then try to install the ROM image. If it still fails, I'm afraid you may need to do a fresh install (wipe the device fully, before making a fresh install of your ROM.). This should fix your problem, though you loose your data. Unfortunately, thats one of the risks of modifying our devices. One that I had to learn the hard way (by hard, I mean hard brick).
At any rate, hope this helps.
Thanks for the quick reply guys!
I have not made a backup of my files.
So now I'm downloading slimkat for a little change..
(also is there a way to create a backup of my files with TWRP and restore them on Slimkat?)
[UPDATE]
I wiped cache / dalvik and then install the Slimkat ROM but the same problem persists, then I did a factory reset from TWRP
and then install the ROM, but still the same
Is there any way to unroot your device from the PC?

I don't have my tablet with me to check for you, however, I am pretty sure I found a file explorer within TWRP. Perhaps you may be able to copy from there. Explore the tool abit its quite user friendly and well made. Otherwise, you can make a nandroid backup to create a full backup of your system and try to extract from PC via WinRAR (if the backup is in tar), or some explorer app... see below for details:

Thanks for the tip, I'm sure it will help me in a future failure!
I have already done everything you said without succeeding anything ,so I'm trying to un-brick it with LG's support tool
and I can not get it to recognize my connected Gpad, so I put manually the model and serial number but still it can't see any connected devices...
Now I'm 100% stuck :/

sorry for what happened. have you tried to wipe all data, and all cache then try to do a fresh rom installation? I am not sure why LG cannot see your device. But a wild guess is its something about your recovery because its no longer stock perhaps???
if you can reach recovery, you should be able to fix the issue by wiping all the data (except external SD), wiping all cache (including dalvik), then install your custom ROM. Have happened to me already although different cause from yours but I was still able to restore it although I did loose all my data. But as I said before, its the price to pay for tinkering with our devices.
Hello guys,
Same problem for me, Stock 4.4.2 with TWRP, the OTA update make my GPad boot only on TWRP, no way to get my system back.
I try this one : http://forum.xda-developers.com/showthread.php?t=2772902
Successful My GPad is booting correctly on Android !
Damn!! I read to late your answer, I install a couple of minutes ago the complete stock 4.4.2 V50020d from LG's support tool.
In a previous post I said I was stuck but not really.. I forgot that I have to press volume + and volume - while connectiong the USB cable to enter download mode
But everyone having the same problem with me should really give a try to what JaymZ37 said above.
Peace to everyone and thanks for your replies!

Oh man that worked, just about to give my tablet to gran dad and got stucked, thanks for this!
So I had my ze551ml / Z00A rooted, was loving life, all was great. Then I tried getting XPosed access and didn't read up on it prior. Anyways, now my phone is stuck in fastboot, I'm able to flash partitions and all, including recovery partition, yet I cannot enter any mode but the hung ASUS logo, or fastboot. I weas even able to load CM's "upgrade to MM bootloader" package, but still the same thing only with green letters where they once were blue..... Please help, I need my beloved phone back.....
I'm not a pro but if you can access fastboot it is just a soft brick and I'm sure many people can point you on the right thread to recover it.
I've scoured the depths of both XDA and the ASUS forums, and while I've gained much knowledge of how I can possibly fix it, nothing seems to work. I go to select "recovery mode" and it instantly just boots right back in to fastboot.....

Thanks -- you can install giovix`s modder tool from general section
Set it up , use`return to stock option` --in that option , first select boot , then after- recovery(both will be stock)
You then can either
A- Reboot to stock recovery ,adb Sideload stock M -- Follow on to B-( to back-up stock before flashing)
B- Unlock bootloader again , flash twrp and root (if twrp version in modder is now 3.0.3.M4 you can flash lineageos)
---------------------------------------------------------------(if twrp version in modder is still 3.0.2.1 M - you will have to flash 303M4 in fastboot or in 3021M twrp.
1) You might be able to, fastboot flash 3.0.3.M4 immediately and forget above A&B completely
For 303M4 recovery see lineageOS in original android development section OP for download link

So I've yet to try your solution, but I do have an update, I was able to, one by one, flash all the stock files (stock as in the stuff I downloaded from asus site) and was almost able to boot to recovery, but when I got to the red triangle android, I couldn't get it to go further. I've heardf alternate key combos for proceeding from there, and tried them all, but maybe I'm just an idiot...... I'll try the giovix solution when I've got time (patience).
**when I tried flashing the cm upgrade package after that, it went back to square 1, so I gave up for the evening.**

Here's the thing. I'm super stubborn, and I think I know everything (cuz I do....) so of course I decided that I could figure something out, so I tried my way first............ didn't pan out.... anyway, I'm finding any time I flash a TWRP file, I have no access to recovery mode. Regardless if I do it manually through fastboot, or CM upgrade/downgrade or even the giovix fix (yes I tried it). My question is this, Where is there a return to stock option? of the giovix DLs I could find, I see a 'magisk root' 'TWRP' 'bootloader unlocker' and 'Xposed' tools, nothing else.... Am I missing something? or am I just skimming over that part?
I do appreciate all the help, seriously. Even if it seems like I'm not taking suggestions very well. It's moreso I don't have access to a computer most of the day, and it's not a huge priority since I went and bought a zfone 3 max a few days ago (decent phone for what it is....crazy battery life)
https://forum.xda-developers.com/zenfone2/general/tool-ze551mlmodder-t3458145
Functions:
1- Check connection status
2- Bootloader Unlocker
3- Flash TWRP 3.0.2-0 M1
4- Full-auto xposed flasher!
5- Full-auto root flasher!
5B- Full-auto root (Magisk+Phh's) compatible with 184!
6- ADB Shell
7- Return back to stock
8- Erase /system, /data and /cache for a clean upgrade
9 (HIDE)- Auto-reboot to bootloader
10- More functions inside!
well then forgive me for not downloading the correct option. I nowhere see this list among anything I downloaded, so maybe specify which is which ('full' or 'auto')....... I'm already downloading both of them again, because I'm not sure which I already had. But yea, one of the 2 only has the 4 options I mentioned.

So i finally see what you've been trying to tell me, and I returned everything back to stock, but I still have the same problem, recovery now loads but system wont boot up. I'll try loading the individual factory IMG files today, via fastboot, or should I use a zip file from Asus via recovery?

In stock recovery - choose update from adb -- adb sideload cmd is >
adb sideload MOFD_SDUPDATE.zip
Put .134 M asus firmware in adb/fastboot folder first rename it to MOFD_SDUPDATE(without zip) before this cmd above and then open up adb and type it in and hit enter.
Just in case you are trying different methods (see if this works )

I'll try it today. Last I checked it was hanging at the ”! Android” screen. But then again I'm not sure I know the combo to get passed that screen, I know it's either power and + or power and - but my only success I got into by button mashing all three keys rapidly, so, yea, I know, I'm am idiot.

EDIT"""" because i got it wrong too , i dont even think about , i just do it
It`s ->
From powered off position
Press Power and Vol +
at two vibes, release power
at boot up screen ,release vol+
in bootloader ,scroll vol up or down to and then select(press power) at recovery selection.
At dead android guy -> press vol + and power for 4 seconds -> release Vol +
You should be in recovery.
i am replying in this post since i have a similar problem, and I am as stubborn as OP. Me posting here is a big step in acknowledging my defeat at last. Hours of digging through the internet didn't solve my problem
I have changed my ifwi and dnx more times than i can remember. (my clean slate is mostly using xFSTK downloader with xFSTK_ZE551ML-sal358-amtech.vn files)
Using the above mentioned method (giovix`s modder tool) to go back to stock i still boot into fastboot, not recovery mode.
trying to unlock bootloader it says on the phone "unlock fail"
Using asus flash tool with raw files i get "gpt command failed"
Using a manual method i get the "gpt command failed" on the "6. fastboot oem partition /tmp/partition.tbl" step
in my opinion as soon as i get some kind of recovery my problems are solved. But have been working four hours on this problem with all possible solutions i could think of, nothing but frustration.
info: current ifwi 0094.0183 (wich should be M)
serial 01234........EF
and using the toolkit on "https://forum.xda-developers.com/zenfone2/general/bl-unlock-ze551ml-toolkit-t3546293" i found out my device firmware version is 198 (wich is probably not good in combo with the ifwi)
little update in a certain config (android 5 / ifwi 0094.177 / stock recovery) i can boot up untill the dead android icon, but with whatever key combo can't get past it... (vol up + power) / (vol down + power)
fastboot flash boot recovery.img (yep i am really desperate to get into recovery) doesn't even give me the dead android.
thank you beforehand!
Last paragraph with android 5 ifwi 0094.0177
Is your serial correct ?
Press vol + once is it correct?, if not you will have to xfstk first again and flash raw (twice) with temp bootloader 0094.1069
See my unbrick video for help
First of all, thank you very much for your reply!
I was not very specific there, the android 5 is not the rom (still wasnt able to flash the rom) its only the files like droidboot, ifwi, dnx, .... that i got form lolipop.
Indeed the serial is still 1234........EF (so not the correct one)
I do understand i have to flash the raw twice to get the correct serial, but flashing raw doesn't work. I get "gpt command failed" every time. (so the point where i have to restart flashtool is not even reached). Also if i try to do it manualy.
I watched your video (thanks it was my first steps into understanding how it all worked) but unfortunatly didn't work for me.
Any other ideas?

Did you get this device in this condition ?
If not, what happened so that you lost serial ?
Anyway , i have never tried this because i have ALWAYS succeeded flashing raw (twice) to correct serial BUT it may work for you.( i am not sure you have a device that can have the serial corrected due to whether its been tampered with previous ) which affects recovery and IMEI.
Usually , xFSTK is used to install temp bootloader - Its supposed to be the lowest level form of unbricking procedure and restores temp bootloader so you can fastboot after-- flashing raw in fastboot via AFT(twice) restores serial -- 1st flash approx 3mins is with incorrect serial and temp bootloader.
After a couple of mins, cmds on phone pauses on RESULT=OK on phone.
You close AFT and open AFT again , input raw and set AFT up -- press Vol+ on phone -> once, serial will be corrected and 2nd flash can be started and left until it boots into android 5 by itself.
If GPT trouble , that link may help.
There is other programmes for starting to create serial and restoring .
Usually people who use these , have to dig deep into buildprop stuff which if tampered with can end up with problem such that you have.
Good luck
see if anything here helps

Hi,
My previous post relates to this one. Due to that problem I got, I had to factory reset my device to get my camera working again. However, instead, my phone rebooted into TWRP and would not boot system normally. When I tried to go to factory mode via fastboot I ended up in endless bootloop. Back in TWRP I tried to restore my backed up ROM from before rooting, but nothing really changed. I am really desperate because I have not find any solutions for my model and I don't want to use other montana models stock ROMs as I suspect them not to be compatible. What shall I do?
Cheers

Turn off the device, boot into Fastboot Flash Mode using vol down + power, using volume keys scroll and select factory mode and device will turn on. the next time you boot up the device, it won't go into TWRP directly. I have faced this issue many times. Hope this helps.

Not in this case. What Factory Mode did was that it got stuck in loading loop playing the Moto logo endlessly for over 5 minutes. Anyway, the phone is now hard bricked so I am facing even larger issue )

Flash stock ROM via fastboot problem will be solved..
As far as people who need play store can flash gapps via TWRP as a same method we use for custom ROMs.
P.S. i will not suggest to buy XT1799-2 because this SKU is purely made for Chinese Market, if you need any custom ROM go to Weibo.com/diyroms and post a request to build a custom ROM for this device.
And there are some custom ROMs available that you can search via baidu.com ( Chinese Search Engine).
I will try to find any ROM and post for you guys and also post. Request to build for XT1799-2.
CHEERS
so have you find any global custom rom for this device ?

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:
needrom. com/ download/bv9500pro- bv9500-root/ (delete spaces)
- 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
- reboot and update or install MagiskManager-v6.1.0.apk
Thanks to Jemmini from 4pda.ru

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.
Bests Regards

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

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.
Hey guys,
I'm still around and still using the phone. It has been super difficult to replace this.
Here's the link for the latest Raw - https://bit.ly/3gue9nK
If anyone figures out how to root this, Please let me know as mine doesn't boot with the patched boot image (Flashed over TWRP, Fastboot - or the new Kirisakura 3.2.2). As soon I flash the stock boot image back, It boots without an issue. Cant go for a full wipe as Im super lazy to format it and set it up again from scratch.
If anyone finds a way, Do let me know.
Thanks !

Hi there, thank you for the share. I'm a bit new, so forgive me for the dumb question. Can I flash this raw if I am still on an early ww 16 version? I'm looking to go straight to android 10. If I can, do I just put my phone in fast boot and click the flashall CMD file? Because when I do that it seems like nothing happens. I have the cable in the side and the files in C drive (unzipped within the folder)
