[Q] Phone reboots to bootloader randomly - Huawei Ascend P7

Hello,
First I used Se7en Rom v3.3. It worked perfectly. Then I decided to update to v3.8 so I wiped cache and dalvik cache. Installed the v3.8 Rom. Wiped cache and dalvik cache again and reboote the phone. It booted just fine, I could choose the language and connect to WiFi, but then It rebooted to the bootloader.
Now I have tried to install every rom that's available but with every rom it boots and then reboots to the bootloader. Can anyone help me with this problem? I really don't know what to do!
I hope someone can help me solve this problem!

I hope someone can help me solve this problem!

You can't mix 2.3 CUSTOM ROMS with 3.0 CUSTOM ROMS ... god knows now what you had originally installed..

Sorry, I made a mistake. Both roms are using EMUI 3.0.

Now I have discovered something strange. I have installed Se7en Rom v3.3 and it boots. I can get to the google welcome screen and into settings etc. But when the phone is booted, the screen glitches and show some weird things randomly, like a cable isn't connected properly. It doesn't matter what ap i'm in. It always shows weird glitchy things.
I also discovered it always reboots to the bootloader after exactly 1 minute and 5 seconds after pressing the power button. So it isn't random, as I first thought.

hmm, now it sais the bootloader is "locked" in stead of "unlocked". Does that mean I have my warranty back? Then I'm just going to send it back to Huawei for warranty.

locked? u wanna tell me u never unlocked bootloader ???
if your bootloader is locked (in green ) then yes .. but u need to have original ROM on the phone not custom..
but dont understand how you can have custom rom on with bootloader locked ???

No haha, first it was unlocked. Now it is locked. I really don't know how I did it but now I have warranty again. So I am going to send it for repair in stead of trying myself.

I had a custom rom and cwm recovery when the bootloader was locked. Now I've deleted that rom and restored the stock recovery, so they can't see I had a custom rom. I think I'm just very lucky

1. try going into recovery and do a factory reset.
2. if that doesn't help, reflash and all your problems are solved.
do a clockwork mod backup before messing around next time

Use LG mobile support tool, also its "stuck" not "stock"
What are you on? He needs to reflash the rom as he changed the fonts and some may be missing, happens to loads of people, no need for a factory reset, just restore the fonts folder or reflash the rom, if you don't have an unlocked bootloader, bite the bullet, unlock ya bootloader and come over to AOSP in which i would recommend a 4.2.2 ROM.. or do the long winded way of flashing the stock Rom, your all giving some real extreme methods, it doesn't have to be this complicated..

Try flashing the official rom with odin. You don't lose any data using odin. You just have to go search for your rom and the tool (odin). I'm not sure that you dont lose any data but I already done that and my data was intact! But it's better to someone with more experience advise you.

Thank you for the reply. May I know whether that can i upgrade it through KIES? I couldnt find any upgrade patch for it using Kies. Lastly, what causes this to happen?
New update: After flashing a latest firmware, the problem still exists. It reboot itself. After screen on for a while not more than 30 seconds, phone restarts. Help please.

No. Is still a stock a rom and even root before. Is an official rom. Cant post screenshot because it just happen very fast. When I flashes the latest firmware, no more kernel panic message but once it finish booting within the first 10 seconds it will auto restart

Nexus keeps rebooting after Firmware update to 5.1

Hi all,
I flashed the factory image from developer.google.com version 5.1 for my Nexus 6. After installing all my phone keeps rebooting and optimizing apps. It keeps doing this and i cant seem to find a way to get in my phone.
I relocked bootloader and cannot unlock it now because it says i need to check OEM unlock in developer options.
Any idea how i can fix this? it looks like im stuck and cannot find a way to unlock anymore to flash something else.
also, i went back into recovery and formatted data and cache. no effects after this.
help

Did you use WUG's toolkit?
I had this, just had to reflash the image again but I didn't relock it first, so cant help with that.

no this doesnt work
because i have no more unlocked bootloader.
@haruyu I'm in a similar situation ... Sadly I see no fix
Only thing I can think of is flashing something in stock recovery (if at all possible) ... But I don't if there is a stock recovery compatible files to flash

As yet, there is nothing we have found to fix this issue. I can't think if a fix anyway. maybe someone more familiar than me will find one but for now no-one has.
im guessing my phone is bricked.

Yes (and hopefully no) .... we can access fastboot, but that doesn't help because (as you know) we can flash stock images with a locked bootloader. I am hoping some of our brilliant devs can come up with a solution (they like a good challenge LOL) being we can get to fastboot, but if not, yes, we are essentially bricked
There's an option in advance that force flashes the stock image...trying going back to 5.01 then 5.1. I tried doing the flash files like some did and got stuck in a infinite bootloop so I went into the advanced thing and done it there.
HI all,
I also faced same issues Nexus 6 keep rebooting after updating to 5.1.
Locked Bootloader
any positive help would be highly appreciated

You could try sideloading the Marshmallow update to see if that helps, sideload it and then factory reset. See if it boots fine then.

ICS can be tricky to root and unlock to bootloader.

Well I have the feeling you might have flashed something not correctly. But I'm not sure what you could have done to get the phone into this state.
If you're running stock try a factory reset. If your on a ROM update it or use another.
Do you have this problem with all ROMs?
