"No service" - Huawei Y6. - Android Q&A, Help & Troubleshooting

Hi,guys!So,last week I decided to install Cyanogenmod 12.1 from scratch on my Huawei Y6.I,first,unlocked the bootloader succesfully,than used ADB for fastboot to flash TWRP 3.0.2.0.Everything was nice and smooth.I did a backup of the stock rom after rooted,just in case it was required later.I managed to install CM 12.1 and GApps.I was excited,it worked great!Very fast.But,later I've found out that it was kinda buggy,so I wanted to restore the backup I did in TWRP.It restored succesfully without any errors,but when I booted in,in the corner where it was meant to show my service,it showed "No service"instead.I wasn't able to call(although I had my sim card contacts in the telephone app).Wi-Fi was working,but that is another story.Than I reinstalled CM 12.1 and the service was fully recognized.How can I repair it?Also,I used SuperSU.Could it be from the kernel?I have a zip file with the stock kernel.I did restored boot,system and data.Please help!

Can you try to flash your backup AND the stock kernel AND the system as well? Good luck!

By system you mean the stock recovery?

Nope, recovery is the recovery (duh )
Boot is kernel
System is... Wait for it... System

Just because you can't get to recovery does not necessarily mean you lost root access. They are not one and the same. LGs are kind of finicky about recovery, If the built in reboot to recovery option from the Power menu is not working, you can try an app like QuickBoot or via adb commands from the computer, or via the hardware buttons like so: http://itechtriad.com/articles/2014/2/27/how-to-reboot-lg-g2-into-recovery-mode#.U14kH_ldWSo
If you actually have lost your recovery (which is unlikely because CM would not change that), and still have root access when booted up with CM - you should - then grab Flashify from the Play Store, put your favorite recovery img file on your storage of the phone, and use Flashify to install the recovery for you. Very easy.

[Q] Going back to stock without recovery boot

I just recently installed CM11 on my phone and forgot to install gapps.. (Noob mistake) is it possible to go back to stock without recovery mode? I have a back up of all my files on my computer that I did before I installed CM11. Thank you.

Yes you can but in order to get back to stock rom you need to have copy the backup of stock rom in /clockworkmode folder present in sdcard..
Install ROM manger.. then go in backup and restore.. select backup it will show you the backup of stock rom..
I have used ROM manager a long time ago so dont know the exact steps..

[Q] [URGENT] HELP! Karbonn Titanium S5+ plus CWM CUSTOM RECOVERY WENT WRONG!

Hi. I own a Karbonn Titanium S5 Plus/+.
I was looking to install a stock 4.4 ROM. So I rooted my phone with rootmaster (I do not own a PC).
I download some unofficial CWM for my phone from http://forum.xda-developers.com/showthread.php?t=2634569.
when Backing up from custom recovery it says Can't Mount/system.
my biggest mistake is that I did not Backup original recovery.
I even went to cyber cafe and tried this method of flashing stock rom of my phone. http://forum.xda-developers.com/showthread.php?t=2718505 But it didnt work at all.
So my problems are :
1.I cannot Factory reset my phone.when i select factory reset from settings, it boots up in recovery.when i select factory reset from recovery it doesnt change a thing.
2.My phone has a update . when i try to update,it again boots up in recovery.I tried updating from update.zip but it gives STATUS 7 Error.
3.Again due my stupid mistake of not backing up while changing the boot animation I am stuck with a custom boot animation. Is there a way I can revert it back to original.?
The company's website does not provide stock rom its devices.
Is there any way that I can bring my phone back to full Factory State (Without PC)?

[SOLVED] Please help me I've messed up my rom AND lost root

Hello I was having problems in backing up data in nandroid using cwm recovery. Some nice guy suggested me to change my recovery so I did.
Now i have messed up real bad, i flashed a philz recovery which I had used in a stock based rom and the backup was successful but then the phone couldn't boot up. So i restored the boot patrition from a previously made backup. This way i successfully booted up my phone and got previous recovery. So far so good. Now i knew that the problem is in recovery. I also had a raw kernel file which I had used to flash the cm11 rom so i flashed that kernel. But then i restated device to find out that i have now lost root access. I tried flashing super su via raw kernels twrp recovery but I saw no effect despite it being flashed. I cannot flash the recovery because the curreny twrp recovery crashes when i try to flash that.
Current situation is that I am getting constant unlimited, system process is crashed, errors and I can see no signal from mobile operator. Wifi is working fine.
Please help me, my phone is almost unusable with this error but I have access to all the apps, functions etc. in case you can suggest me to use it.
UPDATE:
Tried to flash a latest version of cm11 and now booted up correctly. root checker says I am rooted.
got latest cwm as well
Now I need to take backup to see if the initial problem is there or not.
As the issue highlighted in this thread is solved, I will mark this as solved and will reply to future problems (related to not being able to backup /data) in the following thread:

Red Honor Bootlogo & Marshmallow Update Questions

Hello there I have a couple questions regarding to the red honor boot logo and also on how to update from a stock rom with TWRP and root ( also a couple of system modifications ) to the new B331 update.
So heres the rundown, when I first got my honor 5x I did not spend too much time on the stock rom I went ahead and rooted my phone and installed TWRP then made a backup of my stock rom (B151) no modifications other than SuperSU being installed. After that I went ahead and installed CM13 nightlies and updated mostly everyday up until the build July-18-16. I had adoptable storage enabled with my 32GB SD card and I totally forgot to disable the adoptable option before I reverted to my stock backup so when I went onto TWRP and tried to restore my backup I always got an error where it said something along the lines " error; could not find system" but instead of it backing out it continued to restore and bricked my phone. I had a somewhat clever idea to flash any build of CM13 I had on my computer and guess what it booted then I disabled the adoptable storage and booted back onto TWRP restored my backup and everything was fine until it booted and I noticed the honor boot logo had a red "h". I found that weird since I have restored my backup previously and that never happened. Anyone knows what it could mean and how to fix it?
My second question is how should I go about updating to B331? Should I download the stock recovery B151 ( since that is what shipped with my phone and is what my backup is) then revert to my near stock backup, flash stock recovery and unroot then update through cslA's B331 instructions? Or should I somehow fix the red honor boot logo then go ahead with what I stated above or is this all done differently? I am not a newbie at these kind of things I just moved onto more important things in life and simply want to update my phone. My needs for flashing new roms daily are over and I just simply like huawei's UI as it just "works" for me. Thanks to anyone who responds anything is appreciated as I can't seem to get my old skills working again. Haha:laugh:
Fibgerprint aint working right? U cant go back to stock with just a normal twrp backup. Install an update.app through dload for your region and then apply the twrp backup.. Make sure you are on B151 Recovery!

No, my fingerprint is working... I just wanted to go back to stock ROM with root and that's what I got just now I have a red honor bootlogo. Now I want to update to marshmallow but I have a fear that even if I follow the steps onto reverting to stock I may brick it because of the red bootlogo.
So what you are saying is I should download my B151 recovery and firmware to revert to stock then update and from there I should root and install TWRP?
