Hi,
Firstly, sorry for the lack of references in my post, as this is my first one, I'm not allowed to add URLs.
I recently purchased a Blackview BV9500 Plus and I have been trying to flash TWRP, I wanted to try different custom ROMs since the stock ROM for BV9500 PLus is apparently no longer updated (info comes from a Blackview forum).
The TWRP version that I'm trying to flash is 3.3.1 for BV9500 Plus (unofficial).
I have tried different ways, using fastboot flash recovery, using SPFlashTool and flash directly the recovery file, and it looks like the flashing succeeded but I have never been able to boot into TWRP. When I turn on the phone pression the Volume UP key, I see the Blackview logo (which sometimes appears color inverted black <-> white) and then nothing happens, it goes back to rebooting until I let go of the Volum UP key, then it starts normally. I even tried with a different TWRP version (3.2.3 for Android 9.0 Pie MT6771, unofficial) with same results ...
I unlocked the bootloader (ticked it in the phone settings) and did a fastboot flashing unlock, I tried rooted (with last version of Magisk with which I patched the boot.img and flashed), not rooted ... with no luck ... (I even lost my IMEI after a complete format with SPFlash along with the googlekey, fortunately I was able to reflash everything thanks to BV support :laugh::victory
Many thanks in advance for your help, I have been trying to figure this all out for a few days now ...
Best regards.

Hello and first of all thank you for reading. I've a strange problem with my redmi note 3 pro.
i was chatting with it but suddenly it starts to have bootloops (mi logo flashes). I tried to restore it with recovery (it was still not unlocked) but nothing to do. So i flashed rom with the miflash and in edl mode (i tried latest stable, latest developer and first developer fastboot roms) but the bootloop was still here. So i tried to unlock bootloader with unoficial method (official says that my phone is linked to another account, absolutely false but i will come to this point later). Tried to flash zip with TWRP but still bootloops. I was tired and i tried cm13. It worked, phone boots and i was absolutely happy but dialer crashes when i receive calls. So i understand that my phone wants the boot.img of android 6.0 to not go into bootloop. I flashed (via TWRP) latest 6.0 based miui rom and it worked but still with dialer problem. I tried to unlock it but still no go. So i decided to try to sign out of my miaccount (yeah it was still there after flash with miflash in EDL mode, don't know why!) becasue it asked me to enter my password to use the phone when i boot miui 6.0 for the first time.
SO i Have absolutely no idea on what i should do. Phone bootloops when i use a 5.1 based rom, and with 6.0 dialer crashes. That's the strangest thing ever.
I tried many fastboot roms in edl and in fastboot, i tried custom recoveries and stock one, tried to unlock and relock bootloader. I tried basically everything (wipes, system-data-cache-internal) EVERYTHING!
please if you hava any idea i will be glad to try!
I've tried to restore a backup from another RN3P but still bootloop. Maybe is somethig related to the boot.img? changing it makes the phone boot.
Go to a Mi service center. They might be able to help you.
Which gapps you installed after you flashed cm13...
When i used stock package, my dialer was also crashing but when i used micro package, the problem was solved....

I had a similar issue a while ago with a friend's Samsung. The service center people said that it was a RAM issue..
. If you can return the phone to wherever you bought it from, Do it ASAP and get another model...
Otherwise you might have to go to a service center and tell them exactly what you are facing. Before that i must suggest
Try installing a custom Kernel perhaps and see if it still bootloops
For every worst case software/firmware failure, full rom flash would be the one to solve it. Based on your story, it must be the hardware problem. So if possible, bring it to your nearest service center..
i really thank you for the reply but this phone comes from china and i'm in Italy so I have no warranty at all (including the fact i changed the screen) I think i will use it as an ipod. I've posted a log of the kernel bootloop so maybe someone with skills could help me!
that's the log! http://pastebin.com/b3CVcBAT
Hi People, I hope someone out there can help with the problem I have. I'm trying to install TWRP recovery and it results in all Twrp versions 2.xx, i get OPPO powered by Android screen then goes blank. All Versions 3.xx I get the aforementioned screen and it sticks on it. I'm using the unrooted stock version of project spectrum 1.1 atm. I did install the CM recovery when it was around a while back on the device but after bricking it I'm back on stock firmware now and want to use lineageos.
I have tried every method and every TWRP package via fastboot but with no luck, I have been successful before but not now. Thanks
Any luck with it. I'm also stuck with twrp-3.0.2-0-r5.img

Hope it works for you too.
Cheers!
Hi guys, after a long hiatus from XDA , I am now back in need of more advice.
I simply cannot seem to flash TWRP recovery on this phone.
I have followed multiple guides and nothing is working.
I have installed all the necessary drivers and I have tried multiple different versions of flash tool and TWRP Roms.
On an older version of flash tool, my phone just sits off and flash tool finishes by bugging out with an error like "the phone booted too quickly".
I then tried a new version of flash tool and it did actually seem to flash TWRP ,however when I boot into recovery, my phone bugs out for a split second and then boots into standard os.
Can anyone help me?
Managed to fix the issue with some perserverance!
But what did you do ? I got the same problem.
Hi, I'm hoping someone can offer some assistance. I have an Elephone P9000 (normal version NOT lite) that has official Android 7.0 and I want to install LineageOS 14.1.
As per the instructions I used SP Flash Tool to downgrade the phone to Android 6 (Elephone_P9000_20170112) which worked fine.
I then attempted to install TWRP 3.2.1.0 which also appeared to work ok as I could boot into TWRP recovery and all looked good. However when I tried booting the phone normally it stuck at the white boot logo and would not progress any further.
So I reloaded the Elephone_P9000_20170112 rom again with SP Flash Tool after which the phone would boot normally and then tried installing TWRP 3.0.2.8 as I'd seen threads saying that this version definitely worked with the P9000. However this produced the same result that I could boot into TWRP fine but it would get stuck at the boot logo if I tried booting the phone normally.
I have also tried re-installing the ROM but unticking the recovery option in SP Flash Tool hoping that this would leave the working TWRP intact but this didn't work either.
When I try to boot into recovery I get the little Android laying down with a red exclamation mark.
So I don't know where to go now. I can get EITHER Android to boot or TWRP to boot but not both.
Just in case it is relevant, I am using SP Flash Tool v5.1804_Win in Windows 7 32bit. I don't have any SIM's in the phone and no SD card inserted.
Can someone point me in the right direction please.
Thanks
Russell

Thanks very much, that worked fine and AOKP looks really good. When it said install the latest Android v6 it obviously means the previous latest not the current latest
Just in case anyone else is having the same trouble I was:
Using SP Flash Tool load the 20160810 ROM available here: https://forum.xda-developers.com/elephone-p9000/development/rom-elephone-p9000-20160810-t3445897
Then, also using SP Flash Tool, load TWRP v3.2.1 which is available from here: https://eu.dl.twrp.me/p9000/
Then you can use the TWRP recovery to load whichever ROM you like (LineageOS, AOKP etc, etc)
Once again, thanks very much for your help.
:good:
Hello all, so I've unlocked the bootloader via dc unlock, installed TWRP ,flashed multiple treble roms via TWRP and fastboot but my device isn't going into the android system.... I'm stuck at the screen where it says your phone can't be trusted and on some roms it'll get a black screen but the device will read if typed"adb devices" on adb, custom and system recovery and bootloader are working fine but every rom I try flashing won't boot. I even opted to downloading firmware via the Huawei firmware finder but when I look for the LND-AL40 8.0.0.325C(00) which is my build number it's no longer available on their server. I'd like to know if flashing another related firmwares say LND-AL40 8.0.0.221C(00) will work for my phone. ALSO please help on why it's not booting into system or giving a black screen I've followed most of the procedures from various tutorials about flashing treble roms. PLEASE HELP
