Hello, I unlocked Bootloader. But now, I get a Error "Your device is unlocked and can`t be trusted. Your dev. is boot in 5 seconds. Then it starts in TWRP.
Can someone Help me, please? Flashing with Flashtool doesn`t find the device (connection error). Where can i find a flashable ZIP-File for TWRP?? TWRP runs!

Have you tried rooting your blackview a7 with it? No errors?

Okay, i also had the bootloop problem with the rooting tool. But now it is working again without root with the original rom from blackview. regards.
Now i got it. It works with the guide if you format data (not just wipe) before installing the noverty and magisk (Solution from here https://forum.xda-developers.com/lg-g5/help/please-help-boot-loop-device-corrupt-t3434411). Aand if the twrp asks to to be installed after the reboot confirm. Aaand the guide for some reason only install the magisk manager and you have to download the latest magisk manually and flash it with twrp install. (https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445). regards

Hi, I bought a Blackveiw A7 Pro. Is there an official site for this phone? I found some guides for rooting but don't know which is reliable. I trust most on XDA community, but there is not a section for this phone. Thank you!

Hello.
I unlocked the bootloader with fastboot but now i get the same message "Your device is unlocked and can`t be trusted. Your dev. is boot in 5 seconds" and nothing happens.
I even did not get into fastboot anymore to reflash or lock it again.
What can i do now?

I managed to reflash Stock with SP Flash Tool.
- Wählen Sie "Nur Download" oder wenn Sie das Upgrade "Firmware Upgrade" durchführen
- Schalten Sie das Telefon aus, entfernen Sie den Akku und legen ihn nach einigen Sekunden wieder ein.
- Schalten Sie das Telefon NICHT ein.
- Drücken Sie die Schaltfläche "Download", um zu starten
- !!! TASTEN Laut und Leise TASTEN gleichzeitig gedrückt halten. !!!
- UND DANN ERST verbinden Sie Ihr Telefon über ein USB-Datenkabel mit dem Computer. wobei sie immer noch !!! TASTEN Laut und Leise TASTEN gleichzeitig gedrückt halten. !!!
- Der Prozess wird gestartet und ein ROTER Fortschrittsbalken erscheint,
- danach ein VIOLETTER Fortschrittsbalken.
- wenn der violette Fortschrittsbalken fertig durchgelaufen ist können sie die Tasten am Smartphone loslassen.
- danach ein GELBER Fortschrittsbalken. GELB dauert etwas länger, hier wird die Firmware übertragen.
- zum Schluß kommt ein grüner Haken im Kreis.
- Fertig !
- Sie können das Telefon jetzt sicher trennen und einschalten.

I used the correct guide, but i dont get rid of the Bootloader unlock warning and the phone is not booting to system, just to recovery.
So the "noverity.zip" seems not to work

[Q] Phone Stuck At HTC Screen

I fastboot flashed my HTC One S with the LeeDroid provided script and everything went fine. However now when I try to restore from a backup or go into my previous OS (TrickDroid), it's stuck at the HTC screen with the developmental warning. I can get into recovery and bootloader but nothing seems to work.
If there are any methods of me transferring the LeeDroid ROM via bootloader or recovery screen, that'd be great.
Try to flash a recovery via fastboot and boot into it via bootloader. The command is fastboot flash recovery [your_recovery.bin]
It's all explained here http://forum.xda-developers.com/showthread.php?t=1583427

Did you restore trickdroid from nandroid? Maybe you have to fastboot flash boot boot.img or similar again

One S flashed to death-need help pls

Hi Gods of flashing,
I´m pretty clueless. I´ve a One S from T-Mobile Germany (so I´m a crazy german ). I was sick of all the T-Mobile stuff on my phone. So i unlocked my bootloader, installed TWPR and flashed a Viper OneS. I was pretty happy and wanted to try CM stable. There started my trouble. I copied the cm stuff on my phone. Viper One S (or Android I´m not sure anymore ) wanted to do an update, well I downloaded it and let the update install. During reboot the phone went into TWPR ! No start of Android anymore! In the meanwhile I´m sure I´ve done wrong what can be done wrong. OneS All-in-one-Toolkit by Hanson2000, Everything-Tool, trying to flash sideload blablabla...nothing helped.
My screen in booatloader shows:
***Tampered***
***Unlocked***
VLE PVT Ship S-on RL
HBOOT 1.14.0002
Radio 1.09es.50.05.07_2
OpenDSP-v29.1.0.45.0622
eMMC-boot
What is to do that I can use my phone again? I´ve read so many TUT´s, searched the forum but I´m
Could someone please explain step-by-step with easy explanations to me what to do?
I can only use the bootloader, TWPR isn working anymore.
If my phone is nobloe scrap please tell also!
If there are any german guys out there I would be glad to get an german explanation.
Thanks a lot in advance

You most likely have not bricked your phone as you're still able to access bootloader. What i would try next would be:
1. Boot your phone into bootloader.
2. Select fastboot mode
3. From your PC run fastboot flash recovery yourrecoveryimagenamehere.img. This will reflash the recovery. I recommend TWRP version 2.3.x as it has worked great for me and newer versions seem to be having some problems.
4. Boot into TWRP.
5. Mount your phone's mass storage as an USB drive. This let's you access your phone's storage from your PC as a USB flash drive.
6. Copy CM stable zip (or any other ROM you might want) into your phone from your PC.
7. Unmount USB storage.
8. Wipe cache, dalvik and system and do a factory reset in TWRP.
9. Install rom zip in TWRP
10. Reboot your phone into bootloader.
11. Select fastboot mode.
12. On your PC open the rom zip. Inside is a file called boot.img. Extract this into same folder with fastboot.exe.
13. From your PC run fastboot flash boot boot.img.
14. Reboot your phone. You now should boot into the rom you just flashed.
Sent from my One S. Please hit thanks if I helped.
hey, i agree with zaak00,
your phone is unlocked, thats, in this case really good,
from bootloader you can flash a new recovery and from there an new rom.
be carefull with the different versions of the HTC one s (s4 cpu vs s3 cpu), you need different roms for that
you also could repair it with an RUU, than you would have the original Sense back (maybe with an higher hboot, actually i can't definitely say what that would mean in detail)
and yeah, german guy from Bremen here
if you don't know fastboot/adb
http://www.androidpit.de/de/android/forum/thread/470625/HOW-TO-ADB-Tutorial-Anfaengerfreundlich
(das du keine entwickleroptionen setzen kannst ist wurscht, wenn du im bootloader bist und dann mit dem power knopf in den fastboot modus gehst bekommst du damit zugriff)
but i think if you've back recovery you know what to do
just in case, if you are really stuck, write me and we could phone the next days
You can try running an RUU in FASTBOOT USB mode in the bootloader.

Hi guys,
thanks so far. I tried your way zak00. I used an CM 10. Until point 11 everythings worked. I also found the boot.img. But then nothing worked. I put the boot.img to ne place where fastboot was. I had to copy the AdbWinApi also into this folder. Then I hit the fastboot, in the background a cmd window open, some text flew by and the window closed without i could read anything! Rebooting the phone leads to a boot loop.
I think that I have no "OS" on my phone...
A phone call with kr1st1an would be something really cool. Just write me an PM with your number and when you are so friendly to be available...thanks...

when update finished and phone says it will reboot, hold only volume up for 10 seconds. if all went right you will get into erecovery. There you first wipe cache and then peform a factory reset. If all These steps are done, your phone is resurrected! Good Luck! If you have questions, ask Here!

when it is powered off, press only volume down and connect phone via usb cable to your pc at the same time. if it loops, first connect device to your pc, then press power button + volume down button as long till white fastboot Screen arrives
