[Moto G4 Plus Questions & Answers] Waseemahpz:
Unfortunately I forgot to allow OEM unlocking ,now when I am trying to unlock the bootloader it says allow OEM unlocking from developer setting

But phone is already dead

Please help
[Moto G4 Plus Questions & Answers] echo92:
I see that you posted in the other threads about trying to get your device working. I understand you're desperate, please try to post in one place so we can track your issue easier.

However, from the sounds of it you've hard-bricked? Did the blankflash work?

If you're still getting the security downgrade issue, the version of the stock ROM that you're using is too old. Flash the June 2017 or September 2017 stock ROM to get your device working. You can find the June 2017 stock ROM here: https://xdaforums.com/moto-g4-plus/how-to/moto-g4-plus-hardbrick-solved-guide-t3657761 and the September 2017 stock ROM https://xdaforums.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138

Once you've fully flashed either stock ROM, you should be able to toggle the OEM unlocking toggle.

[8525, TyTN, MDA Vario II, JasJam ROM Development] dpswatson:
I have had a scout around and no one seems to have this problem so thought I would run it by you all..

I was using Schapps WM6 ROM (6.0) until a few weeks ago when I decided to upgrade to a Kaiser. I decided to reflash the Hermes ROM to T-Mobile UK's official WM6 ROM so that I could flog it. Now the camera comes up with no picture but Green lines. The picture reacts when the camera moves so it can't be the hardware - could it be a driver issue?

A hard reset does not work. Before I attempt a different ROM, I wondered if anyone else has this issue or had come across it.

See the JPG.

Cheers

p.s stuck the thread here in the WM6 forum because I think its s/w and therefore ROM related.
[8525, TyTN, MDA Vario II, JasJam ROM Development] softonic123:
believe me, its hardware related...

probably try cleaning the camera contacts (if thats possible)...

It's for sure no software issue...

you should look after a take apart direction and follow it to clean the contacts...

Regards
[8525, TyTN, MDA Vario II, JasJam ROM Development] dpswatson:
Thanks, after a change of camera software and ROM it still shows. T-Mobile give two year warranties over here so hopefully they will repair to free of charge. Although if I can get into the handset without them finding out it will be much easier if I can fix it myself - HTC are not that good at admitting to faults with their products.

i have the same problem on spv m3100 and i am desperate!i don't know how but after sometimes and a lot of try suddenly the camera make good photo but after i put a new rom the prblem come again!did you think is from contact?i should open my spv?hmmm... risky operation
[8525, TyTN, MDA Vario II, JasJam ROM Development] softonic123:
i can imagine it's form the contacts... but a hardware failure in general (camera related hw) is the most likely for this kind of symptoms... if i would be you i wouldn't open it, if i had warranty left ;-)

When there isn't any recovery partition , why u want to flash it to recovery

Instead of flashing directly, boot into recovery.

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] pvineeth97:
Yeah you are right. I need to make ZIP of some sorts. I know it is A/B system so recovery is stored in boot partition. I will update the flashing part in some time.

this is incorrect. if you want to boot to twrp recovery then issue the command "fastboot boot twrp.img", not the "boot.img".

It doesn't work either, i've tried also renaming it to ,,recovery.img", still the same thing happened...

Same result printed out of cmd and the device restarted itself... After that restart, wifi stopped working, device started showing MAC 02:00:00:00:00:00 instead of its own... I had to restart the device once again to get wifi working...

Unable to Flash or Boot into TWRP on Xiaomi MI A1

I downloaded the TWRP . My phone is Unlocked Officially with MI Unlock tool. I have enabled USB debugging and OEM Unlock.

I tried to Flash the TWRP using "Fastboot Flash Recovery TWRP.img" This failed. I am getting an error "Failed : (Partition Table does not Exist).

I also tried to see if i can boot into The Twrp. "Fastboot Boot TWRP.img". The Phone just shows blank screen and nothing else. I have to just reboot the phone and nothing can be done.

Now WiFi isnt working and if I turn off the device it goes to bootloop again when I turn it ON and have to start over with boot to TWRP 3.1.1.0 I dont Know how to solve it and to be worse it is my wifes phone so she will kill me if the phone goes off and she isnt near me to fix it.

Hey

my One plus 3 start acting strange.Its battery is draining too much.

its getting heat up while in no use. suddenly apps stop working

any solution?
[OnePlus 3 Questions & Answers] rob rich:
Screenshots of your battery screen after draining would be good. Then, we need to know which Rom you are on and if you made any modifications (like root, other kernels, sound mods....). Most of the times it's just an app that's gone wild, but to know anything, we need more information from you of your setup :)
[OnePlus 3 Questions & Answers] TNSMANI:
Restart your phone. If you have custom recovery, wipe dalvik cache and cache before rebooting. Without further info, that is all the advice I can give.

What did you do last before the drain started?

Is it the hardware I should check when getting a device that support this?

Like Bluetooth 4.1/4.2 or is it something else I should look at?

Hi, am i correct in believing that updating a custom rom is not possible if i have implemented androids adoptable (sd as internal) storage?

thanks
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Not 100% (I don't use adoptable storage), but my understanding, you can flash a custom ROM, but will need to format the SD when you do so. Obviously, you will lose your data when you format. So backup data to an off-phone location (cloud, PC, etc.) before doing it.
