You don't have to unzip. In winrar (i use this app) you have to browse into folder where are located the file then you have to drag the file that i share directly into winrar that replace only this file without changing nothing else.

Then you put the file on internal memory and WITH STOCK recovery it should work.

[Android General] rimix2:
No luck even with chinese version (the latest present on the site).

Honestly I cannot understand why it does not work for me... (same ROM...) I'm wondering whether there's any other option

EDIT

Tried again SRS root with no luck (I think that srjroot is just a typo).

I was about to try Bin4ry exploit but it got too much complicated for my knowledge...

EDIT2

Tried also with Kingo root, at the first reboot the device jumped into fastboot mode and I had to disconnect/reconnect the battery to restore it... I definitely need some help if possible, any working method failed with me (still cannot argue the reason, maybe new hardware? I bought 2 days ago)...

appreciate any hint

I posted a zip file earlier on in this thread, give it a try.

rootgenius will work, here are all files for your crown,

as recovery, ebr, rootgenius (engl. version) and supersu, you will not need the instructions (in german)

but you should install ebr as you like, touch recovery, then doing root by rootgenius,

remove kinguser app by root browser and install superuser.zip using recovery,

tested with kk 20140827,

Hi rimix2

Flash again the 20140924 update from needrom , root with ROOTGENIUS and after that apply the OTA update.

If you update to 20141015 (OTA) rootgenius don't work.

Tried this official update and found that battery life is very good. More than 2 days with wifi and 3G always on , without gaming , just a few phones (about 120 minutes of talk).
[Android General] rimix2:
thanks! I'll try this way.

as I'm not really confident with ROM flashing can you please suggest a xda thread where I can read how to do that? will all my data be deleted after this rollback?

tks again

EDIT found the instructions on needrom, the data will be wiped. I'm just worried about battery calibration, tried once on an old Galaxy ACE (JB ROM) and the battery calibration was kaputt after that

Hi

Todaj i root my blackview crown wtih root genius and than i paste this :

# Touch screen calibration and scroll responsiveness

debug.performance.tuning=1

windowsmgr.max_events_per_sec=200

view.touch_slop=8

view.scroll_friction=1.5

view.minimum_fling_velocity=25

touch.pressure.calibration=amplitude

touch.pressure.scale=0.001

to build.prop. But now my phone wont start, it just show blackview screen and then black screen. How can i fix this? i have original rom and recovery, and if i go to recovery mode and then apply update with adb and text adb devices, it show device and sideload, if i go to chinesse recovery show device and offline. What can i do :)? how can i install custom recovery? and i think that usb debugging is disable, and sp flash tool does not detect my phone.
[Android General] Konrad70:
You must use sp flash tool to recover your backup that you have made with mtk droid tools (assuming you have made it). If sp flash tool does not detect your phone... Ehm... This is not good thing.
[Android General] kokuca123:
No i didnt make a backup ://
[Android General] Konrad70:
So you have to download the official update from blackview.hk and install following his procedure that someone was post in this thread time ago... I didn't never made so i don't have any more suggestion.
[Android General] kokuca123:
Is it mybe post 55 and 107 :)?
[Android General] Salgadinhu:
Hey guys,

It looks like that the update on needrom is really official, blackview as posted on facebook the link of the update.

So, from now on we will get OTA updates... I hope :)
[Android General] rimix2:
but actually the last release seems impossible to root... so don't upgrade to the last one if you have not rooted the phone. I havent tried a rollback+root because I need the phone for work, I'll try when I have some spare time
[Android General] shadow78:
Kingo root works perfectly. Im not sure if it works after the ota update. I have rooted mine before the ota..
[Android General] Ito_:
http://download.chainfire.eu/589/SuperSU/UPDATE-SuperSU-v2.16.zip/ more or less the same thing I posted earlier. however, titanium backup does not work with this one. TB did not work with chainfire's version even when I had the old rom and I had to use koush's version to get TB to work. (and koush's version does not work with the 20141015 rom, manual restoration yayy!! :p)
[Android General] rimix2:
already tried that one (with 20141015): after the first reboot the device jumps into "fastboot" mode (actually it's just a black screen with "FASTBOOT MODE" written on it...). then Kingo lost the connection with the phone and I had to plug out/in the battery to restore.

now I'm making a full backup with HOLO (Helium is not working, no connection with the phone :( )

EDIT

during the last days I found that the phone loses the Audio Profile settings and SIM management settings (and maybe others I didnt notice). I did nothing to encourage this behavior (like reboot, sd removal etc).

Anyone else found this particular behavior? Can this be related to known problems in 4.4.2?

Did you try a factory reset?!

---------- Post added at 08:27 AM ---------- Previous post was at 08:23 AM ----------

Try to install the latest update... You can download through the blackview.hk facebook... In my case solved all the bugs that i have.

Try factory reset. You can boot into recovery holding the power and vol down. Then wipe the phone.

Blackview Crown - battry drains build 20141015

Hello

I received this phone on 11 th Nov with Build G807_D1_H1_blackviewV1.0.2014.10.15.

Last 2 days i noticed battery draining issue. Suddenly drops to 0 from above 40%. after searching ggogle and various XDA forums, i think this build would have already take care of battery issue. Am i correct?

Also is there anyway to wake-it-up by just touching screen? without pressing power button which is very hard to press.

Thanks in advance for your updates.
[Android General] Salgadinhu:
Yes, that version shoudn't have battery issues. Try a factory reset...

Regarding the other question, i don't know if there is a way to wake the phone by touching the screen, but maybe that wouldn't be the best option...
[Android General] rimix2:
If you find a way to root it just let us know ;)

For the wake up, you may use the case provided with the phone, wakes the device when it's opened (altough my case doesn't close perfectly...)
[Android General] ERICKGTZM:
I did this before, but always I have finally the screen to ask a PIN number to unlock the phone!

Nothing works! And the telephone ask a PIN number to unlock, number that I never wrote to lock the phone!

Scatter File + Newest Rom

Hello XDA,

I've also bought the Blackview Crown but I'm having some serious issues probably due to my old firmware (20140827)

I'm getting continuos wifi disconnects and random reboots. I wanted to update it to the newest version, however the old ROM doesn't have an OTA update function and Blackview has removed the update files from its Google Drive account. So can someone please upload the scatter file + Rom which supports OTA update so I can update my Crown.

They also didn't respond upon 2 emails, which I sent 4 days ago.

Thanks in Advance!

Hi!

Here is the full rom . Rooted and TWRP recovery included Updated to 20141015 , so you don't need to update now but later if any update is available OTA , it's working.

You can flash with SPFlashtool.

TO kolja123

Please let us know if new firmware helps on your problems!. I do not think the problems (getting continuous wifi disconnects and random reboots) are due to 20140827! That "old" firmware works fine on my Crown:) BUT my phone can NOT call or send TXT or receive calls or txt. (Phone register with network). Same SIM cards works perfect in my Kingsing T1. I think Blackview has a big quality control problem, when they sell a phone without detecting these problems. :(
[Android General] andydgg:
still can't upgrade to 20140924 from 20140702, given up tbh, I'll just put up with the sticky screen and poor battery life.
[Android General] cupi1234:
You can upgrade with the rom files I give. Use SPFlashtool. First install the drivers for the phone , power off your phone , run SPFlashtool , browse for the scatter file , click on the big Download button , and now connect your (powered off) phone to the pc and wait for the program to finish. Disconnect your phone and power up!

Here are the drivers and the flashtool: https://mega.co.nz/#!e1MXXCQZ!ec-KyIWLWw687B05N6D6xGy9ZSZwu8GZMYFIEtFXSvU

hmmh, i still have one bug...

I can make calls, but I've to turn on the speaker, to hear the called subscriber.

if i turn off the speaker (seet by default), i hear nothing, and the called subscriber hears me very low.

If I turn on the speaker, the called subscriber hears me well - and I hear him too - but also all the people next to me.

the micro works, google sound sound search app works fine

any suggestion?

rom is newest 20141015, rooted with twrp 2810, i did a full wipe with factory reset - same problem

seems like the earpiece is damaged, i tried the App earpiece, no sucess...

[Android General] Blackcrown:
I don't know why people keep posting here that our Crown can only be rooted by strange one-click-tools like Root Genius or Kingo Root. I used the trusted supersu.zip by chainfire and flashed it as an update from TWRP recovery (should also work from CWM).

Et voilà: We are rooted. And yes. It works with the latest firmware 20141015 as well.

Problem with disconnecting simcards

Does anyone has a smilar problem with Blackview Crown? My simcards tend to disconnect several times a day. I cannot turn them on in the setting, they seem active in the setting. Only a red crossed circle appears on them on the top bar.

Because of it I'm missing calls until I reboot the phone, that's the only thing that helps. I restored factory settings, rooted the phone and installed the new updated from November, but it didn't help.

Does anyone has a solution for this problem?
[Android General] Blackcrown:
Never heard of that. Sounds like a hardware problem to me.
[Android General] aerobomb:
hello! need help here.. how can i edit build brop?? i also have touch problem on lower part of the screen.

thanks! =)
[Android General] Blackcrown:
Do you have the latest firmware? For me, all problems (especially the battery drop at 40%) are gone with firmware 20141015. Plus I don't experience those touch problems. So - no need to edit build.prop.

However, if you badly need to edit build.prop, there are several ways for example with adb from your PC. Or you can install root explorer on a rooted device from the market, go to the file, save a copy for backup purposes, then set build.prop r/w so that you can save the changes, then edit the file carefully and save. Reboot.

[Android General] Stripu:
Potential solution for the touch screen issues!

Just as a heads-up to the people who have the touch screen issues on the lower part of the screen:

I might have found a solution - i heated the affected part of the screen with a hairdryer for about 5 minutes (i had to remove some stuck glue - put on by my kid) and after the procedure - presto! - the touch screen issues had miraculously disappeared!

If you guys try this, let me know if it works for you too. I'm guessing it's some kind of factory issue, as probably the glass might not have properly bonded in the oven or something..

Good luck!
[Android General] aerobomb:
Did you remove the screen or just reheat it on top of the screen? I'm afraid to void my warranty.
[Android General] Stripu:
I had the protective film removed (removed it after a couple of weeks when i bought it). Otherwise, there was no dis-assembly.

I don't think the warranty will be void if you remove the protective film :P
[Android General] aerobomb:
I will try it tonight. I hope it will work to my phone too! =)
[Android General] Blackcrown:
Looks like I was 2 happy 2 early ... Had the battery drop again, even with the October firmware - according to Blackview this problem should have been fixed in the August update. And the touchscreen appears to be over-sensitive now. Seeing a lot of people complaining about different hardware issues, I suspect that Blackview's build quality is not consistent. You may be lucky and get a decent phone - or not. I won't complain to much considering the price tag of the Crown, but I cannot recommend this phone.

After formatting crown with sp flash I can't anymore flash any custom rom???Anyone know answer???? IMEI lost during the process of formatting but I have backup...
[Android General] andydgg:
Had mine on internet, streaming tv, and watching hd film for a journey lasting about 7 or 8 hours. Started with a half charged battery and changed it for a fully charged spare battery half way through, battery just about out at the end, lot better than carrying a laptop, my laptop battery lasts about 6 hours. Bottom corner of the touch screen is annoying sometimes but not that much of a problem tbh, it does look like a hardware issue. I haven't bothered updating the software, it's too complicated and I see too many problems here and in needrom. For just over £120 I'm 6 monhts into it, and would recommend, it's a good phone with few flaws. I just want it to last a year, then I'll pass it to a family member and I'll upgrade to a 4g dual sim.

Sir What's new about the new update Blackview_V1.0_20141015 will it fix the battery issues and and other bugs? how long will it charge from 0% to 100% and how long will it drain from 100% to 0% in hours plz.... thank in advance.:laugh:

What can you say about the battery performance? will it solve the battery issue? how long will it charge from 0% to 100% and how long will it take to drain from 100% to 0% in hours?..
[Android General] aerobomb:
standby time of the latest update is so great! 3 hours of standby I still have 100% battery.. but while using the phone with wifi On?? it will drop from 100 to 85% in 20 minutes more or less.

Tought i write a Reply about the Battery

The battery in my Crown is also a super Weak one and i decided to do a Little Hardware Mod.

I read that the 2300mah of the Crowns battery are fake and that it has only approx 1400mah

So i took the Batt pack out of a Htc one X+Battery (2100mah) And soldered it onto the Crowns battery Cirquitry (both are Lithium ion pack and not Polymer). I still have to test things out but it seems that it lasts much much longer now,but the Battery Drain is still very bad so i guess its caused by the badly developed Stock rom.

Why Bad Developed Stock rom? well here are some things i recognized

Widgets never stay and dissapear after a reboot in the Stock and my Apex Pro launcher

Battery Drain even if the phone is not used

Extreme Battery drain while using only the Wifi Hotspot

Sometimes Strange Performance issues in many Games and apps

Very Slow/laggy Cam in many different Light Conditions

Audio Settings Reset themselves after each reboot
[Android General] Wahazz:
Hello it has been a long time

due to al these issues and many others, I am selling mine and taking a note 2
[Android General] Skolotaie:
I found a few ways to get rid of some problems tough,To take pictures etc i now use the App called Open Camera (Its free and just amazing) Ofcourse it isnt much better than before but it really helps.

And the Widgest .... Now they stay even after a reboot but i dont know why,i use a few Mods now too.

I have Installed the Mtk Universal script pack (wich got removed here on XDA) And the Mtktweak app v14

Also uninstalled all not needed System Apps and froze the Stock launcher

My Audio settings Magically also stay now + Viper4android works finally

Xposed Installer and Gravitbox also work perfectly and i applied the Kitkat SD fix

And about the Battery

If anyone could give me a good advice for a accurate Batt monitor app let me know,atm i use Gsam Battery Monitor + the Kitkat Root helper for this app. Gonna post screenshots at the end of the day and i think i have a heavy usage haha

Wlan hotspot etc and i will enable gps for a while too make a good Batt overview with the HTC pack inside but still face problems like Shutdowns when it comes to 25% or sometimes even higher Batt percentage wich happened with the Normal Battery too
[Android General] Skolotaie:
Silly stuff ahead.

I never used a Battery app with the Stock Batt pack but with my Htc batt Bastard look please xD

And if a Dev might see this Dangerous and (i have the balls) Screenshot stuff maybe give the Blackview Crow users a Rom wich actually makes the device Good? ;p

Jk now to the facts you can see everything in my attachments

I love to do such things and want to BEG

DONT DO THIS WITH YOUR CROWN if you are not stupid or Hyper silly!

But my feeling tells me that the Battery life got Insanely improved (on my device) Placebo?
