I've encountered a problem that I'm thoroughly convinced no one can help me fix (mostly due to the amount of time I've already put into seeking a fix). I recently rooted my phone, and it worked, but now I am starting to experience problems. I used VRoot to root the phone. All of the problems I'm experiencing happened after an attempt to boot my phone into recovery mode using the ROM Manager application.
PHONE INFORMATION
Model # - VS870 4G
Firmware - 4.1.2 (Jelly Bean)
Kernel version - 3.4.0-g2696711 [email protected]
Build # - JZO54K
Software version - VS87012A
Issue 1:
My phone no longer connects to wi-fi. Upon selecting the connection and inputting the pass-code the phone only saves the connection but makes no attempts to connect. It can't possibly be the router that is causing the issue because the phone was able to connect flawlessly before I tried booting into recovery mode.
Issue 2:
My phone's status is currently "Rooted" but it doesn't behave like a rooted phone. When attempting to install applications that require root, the applications insist on informing me that my phone is indeed not rooted. When attempting to re-install lost applications after the numerous amount of hard resets I've done, the applications are shown to be already installed yet they are nowhere to be found on the phone.
Issue 3:
Even after installing the updated USB drivers (and multiple re-installs) any computer I plug the phone into refuses to recognize the phone if it is in Emergency mode, yet it is still recognizable in the default mode.
Issue 4:
In order to install apps, I have to download the .apk file because my phone will not connect to Google Play even when I'm directly connected to the internet via usb or using 4G. Various other applications that require an internet connection refuse to work as well which is making the troubleshooting process extremely frustrating.
Fixes I tried -
Reboot, hard reset, battery/SIM/SD removal, selecting the "Avoid poor connections" option, reset router, re-setup wireless connection (tried without a pass as well), switching the IP setting to "Static" (doesn't allow me to select connect if it is on static), toggled the 802.11g only mode, toggled the routers DHCP server option, unrooting phone (SuperUser deems it impossible due to the lack of a su binary, which I don't understand seeing that when the phone is in emergency mode the status of the phone is "Rooted"), installing a stock firmware install via KDZ, as well as failed attempts to manually install CWM (my purpose of trying to manually install CWM is due to a lot of the fixes I found having "being able to boot in recovery mode" as a requirement, which my phone lacks)
So here is/are my question(s):
If I'm not able to unroot the phone, is taking the phone to a manufacturer no longer an option?
Is there a way to "reset" the wireless hardware/software on the device directly that works around my current issues?
Are there any alternatives to installing the KDZ stock firmware file where the device isn't required to be in Emergency mode?
I'm still not exactly sure what a su binary is but is there a way to install it independently?
Thanks in advanced~
And the intricate thesis pattern.

Any luck? I am having basically the exact problems you are talking about and was wondering if you found a fix or what you ended up doing. Thanks.
do a rollback is needed
Hi all, I have been having a problem for the longest time now. My s6 refuses to connect to any pc. My first laptop had windows 7 on it and the s6 would successfully connect to it. That laptop is no more and i upgraded to a new one with win 10 installed on it. This laptop along with 2 others windows 7 completely refuses to connect to my phone. I think i have tried every "solution" but nothing works. My phone is rooted with a custom rom and the fast charge also refuses to work. I need to be able to connect to windows so i can reinstall the original firmware for a warranty exchange. Yes, i have all sumsung drivers installed, i have the original cable (and more), i tried smart switch, it still doesn't work. Any tips will be greatly appreciated. Thank you
Go to: Settings -> About Phone -> Tap on the build number 7 times to enable Developer Options -> Go to Developer Options and enable USB-Debugging
Now try connecting it to your PC

can someone please help me sort this out? I have tried numerous methods to get the phone to connect, all of which has been unsuccessful. Everyone knows the struggle of not being able to connect to windows.. thanks in advance.
The problem could be the USB port on the phone. Or the data / charging cable may be faulty.
Try download Shortcut master lite from playstore, run secret code explorer in it, then code 0808, and set AP and MTP+ADB to see phone as disk in windows, this helped me, hope it will help you.
I have had my S6 for just one month and the fingerprint scanner has stopped recognizing my fingerprint. The device wont recognize my backup password or google account either. I am pretty sure my backup password is not incorrect and I know my google account information is correct as I still have access to it on my computer. I am able to use android device manager to call and send messages to the phone, but android device manager no longer has the unlock option. I have contacted google directly, but they were unable to provide any solutions. I have also contacted my service provider Sprint and Samsung with no success. I did not register with Samsung find my mobile prior to the incident. I don't have any of my files backed up to the cloud. I recognize that factory reset is the only option now, but I would like to create a backup or at least rescue some of my files before the reset.
I have wifi turned on, but USB debugging is turned off. When I connect to Samsung Kies or Smart Switch, I am prompted to unlock the device.
I have looked into using TWRP to recover files from the device, but I have read that the program no longer works with the S6 since the latest update.
Is there any way to pull files from the device while in recovery mode? Are there any other options available?
I am willing to compensate anyone who is able to help via PayPal

Go back to Android Device Manager and select Lock Device. It should allow you to set a new password to get into the phone.

This results in an error message that says the device is already locked and so a new password will not be set

Is it still asking for the backup password or is it just asking for the Google account?

It's asking for both. When I enter the backup password wrong five times, it then asks for my Google account

Hi, I'm using win 7/32 and I did not need usb drivers. We restarted the windows, in F8 I turned off checking the drivers' signatures and then started the windows. On the phone I enabled the developer options and the usb troubleshooter. Then I plugged the usb cable (on) to the computer. It will start downloading and installing the drivers. You have to run all the options for connecting the phone to the computer (usb configuration), from simple loading to MTP, PTP and MIDI. When all the drivers have been installed, restart the computer and turn off the phone. At me, (Cubot x 18), I have not removed any battery, neither sims nor microsd. Just with the phone off. When you restart your computer, start the sp flash tool, choose MT6737T_Android_scatter for what you need, choose the option and activate it, and finally plug the phone off to your computer. From now on, everything has to go ... That's the method I use. I was frankly amazed that she was running without a battery in the phone; and all the way to him, just stopped.

Hi just got my phone and the mobile data is disconnected. I cannot turn it on and when I try to go into phone settings and try and change the radio band it crashes the application. The option to enable mobile data is there but has no effect. Anyone know of a fix or maybe how to download a new modem? Tyia

Hello, I think you need to set a new APN. To do this, you must go into Settings-Wireless & networks-More-Cellular networks-Access Point Names. At the top of the bar you will have to press "+" and you will need to configure the new APN according to the mobile phone operator from which you have the SIM card you are using. Once configured, you'll need to save and check it as an asset, the one that your phone will use. That's all. And there would be something else. At my side, I can not catch 4G, it gives me connection error. So I set it on 3G, from -preferred network type. Hope to help.

Thanks mate. The correct apn had been set and it shows 4g connection at the top but simply refuses to connect to mobile data. It all says its switched on etc. When I type +*+*4636*+*+ into dialer screen to bring up phone settings it is there that it says mobile data disconnected and it simply will not switch on.
I've also factory reset the phone and it won't connect to mobile data then either. When I try to change the radio band it crashes.

Wi-fi going? Perhaps there is something on / off in your phone that limits your access to your mobile data network (billing cycle, data usage, roaming, or anything like that). Frankly, my knowledge is limited, I do not know what else it could be. If wi-fi works, try updating it, you may be lucky.

Thanks mate. Nah me neither. WiFi does work but no joy with mobile. There's no update available and a factory reset never cleared it. I think the issue lies with the radio band. It simply crashes the application whenever I try to access it.
Not receiving incoming calls when in VoLTE
Since my carrier is activating VoLTE through its network
I cannot receive incoming calls. If my phone receives only the 4G signal (without VoLTE) the phone works perfectly. I tried another sim card of the same carrier...same issue! If I put on the phone a sim card from another carrier it works fine, but I think this carrier is not using VoLTE yet. Using the *#*#4636#*#* menu I switched off "provisioning VoLTE" option...but after a few seconds it turns on again automatically. I do not know yet if the problem is linked to my phone, carrier or a problem on Android. Does anybody can help me? Thanks in advance
PS: my phone is running native Android 7.0 and it is updated with the latest firmware version
Try a drastic solution. Reflash your phone. The problems are with MTK firmware structures, MTK firmwares usually results in lost IMEI or NVRAM issues.
I am a fan of anything MTK phablets, tablets, phones and owned mostly Lenovos about 7 devices, all rooted with TWRP. My advise is to reflash the phone (since we already have the firmware), if it doesnt work the first time after reflash , you probably need to reflash a few more time and you will find that after every reflash there will be random functions and apps broken (after the next reflash the functions and apps are OK but others broken) until you will have all 100% OK. That is my experience with MTK SoC.
Good Morning!
Can you tell me if this procedure works on the new model, the P20? Uses Oreo 8.0.0 with Kernel 3.18.60 ...
Thank you very much
Me too

Hello guys,
I've the same problem with my X18. Everything works fine. My SIM is active and registered and in the notification bar there is a 4G-icon, I can make some calls, receive SMS and so on. But if I use mobile data, the connection will be interruped after few minutes and in the settings dialog the SIM card is disabled.
Reboot, changing SIM slot takes no effectes. This error is reproduceable.
The device has 3 APN-Settings. Is there any oppurtunity to delete these settings, so that I can receive new APN from my provider or to define it manually?
Best regards
Dan
Good review thanks..
I know this is off thread.. I want to install twrp and magsik on my cubot note 7..
Can't find any info anywhere....
Do you know a safe method pls?
Hi... I am new to this forum and my concern is, have been using oppo A51w recently i have changed pattern lock and i could not able to remember it. I tried lot but i cant unlock the phone. The phone has important data so, i dont want to hard reset the phone. I tried with Android SDK tool because of USB debugging enabled in my phone, but i could not able to authenticate RSA key fingerprint due to phone was locked.
Is there any way skip the RSA key authentication? else what is the other solution to unlock?
Mobile status
OPPO phone with USB debugging enabled without internet.
Kindly suggest unlock method.
