Help (OP2) - OnePlus 2 Q&A, Help & Troubleshooting

Hello guys , so here is the deal : I flashed cm 12.1 unofficial by Temasek and now i want to go back to Oxygenos but when i flashed it , in the start the phone stuck on "checking for updates" and nothing happened.
Is there a solution, or I did something wrong .

For normal, it should skip this step after a few minutes (timeout). And if you want help: Please write a proper title for your topic - just "help" isn't that good.

S4 DUOS, GT-I9502, can´t finish “Odin updating” even for stock roms

Hi everyone, I´m really pissed about that issue; I´d really appreciate any help and thanks in advance to you all.
Story: I was using Sva´s rom for kitkat, everything normal, then I´ve seen Sasikas´s for lollipop and decided to try it out. I flashed the original firmware and then the custom, both via odin, used them normal as usual. For some reason, I decide to compare the new sva´s, also for lollipop and when I tried to flash, THE ISSUE BEGAN!
Issue: after doing the normal odin process, when the message “complete” shows up and the phone reboots, the bar of updating progress stop about 25% and the phone reboot to the normal mode, but only with a black screen. This is the screen I´m talking about: 3w generacionandroid.com/wp-content/uploads/2014/09/Android_updating.jpg
What I already tried and it didn´t work:
1 – factory reset after the “boot”; I think the problem is that the “system isn´t being write” so …
2 – different roms, both custom and stock; something interesting about this is that the point of the bar that resets the phone varies according to the rom I use, just as follow:
Rom lollipop: at 25% of the bar the system restarts;
Rom kitkat: the bar jumps from 25% to the end and boots the system until Samsung logo. I noticed that the carrier logo sound is cutted in the end.
I can freely install any recovery and enter dl mode.
By the way, the bootloader file must be flashed at pda or bl in odin?
Flash the bootloader file in the BL slot.
about the bootloader...
I´ve installed a bootloader to try the new lollipop in sva´s rom, maybe because of this I can´t flash anymore? I´ve found this info about bootloaders, could someone tell me if I´m thinkg right about it?
"In literal terms, bootloader is code that is executed before any Operating System starts to run. "
This way what I need is a bootloader for kitkat or previous? Where can i find it?
cry for help
almost givin up...
so, happy new year to everyone, I´ll wait until January to check any replies, otherwise selling for parts. ='[.
Shortening: I can enter recovery and dl mode BUT not getting to install roms;
I know I fixed selinux permissions once and installed a bootloader said to be to install a version of lollipop, that´s all new stuff I did.

[HELP THREAD] Stuck in a "Your device has been unlocked and can't be trusted" loop

[HELP THREAD] Stuck in a "Your device has been unlocked and can't be trusted" loop
Hello,
I am using a Motorola Moto G4 Plus (12GB, Android Nougat 7.0) and i tried unlocking the bootloader/ flashing a custom rom because I already managed to do the same with my Moto G3.
After unlocking the bootloader I successfully installed TWRP 3.1.0 on my Phone.
I then wiped all of my data including the system and flashed Cyanogenmod 14.0 (2016-09-13 UNOFFICIAL athene) and installed open_gapps-arm-7.0-mini-20170603.
My problem is that when I booted my phone there is a message saying:
Your device has been unlocked and can't be trusted.
To learn more, visit:
motorola.com/unlockbootloader
ID: N/A
Your device will boot in 5 seconds.
And i have absolutely no way of getting rid of it or shutting down my phone. Every 5 seconds my screen turns black for like one second and the message appears again.
I would appreciate it if you guys could help me access my phone.
P.S. It's my first time posting, please tell me when I did do something wrong

Ask and answered yesterday in help thread for example. Please have a look at here and the posts before and after https://forum.xda-developers.com/mo...-question-noob-friendly-t3526598/post72528225 for the message at boot.
Because of your bootloop after displaying of the message your device can't be trusted": why you install the abandoned cm14.0? Use newer LineageOS or other supported roms instead of that discontinued one.
I think it's because of the newer twrp maybe. Did you tried an older version like twrp 3.0.2? Did you tried installing the rom without gapps? Maybe the gapps doesn't play well with the old rom?
I got same problem but i solved it.. if u need to solved this problem Flash your device. It works 100%.^_^

If you have nothing useful to say, say nothing. It can irritate new users.
I guess you should try some other ROM as suggested! You can go to Recovery by using Power+vol down Button for 5 sec... that should take u to bootloader and then recovery and other options!
Let me know if that works!
Ummm.. just read the post again... moto g4 plus (12 GB)... I hope that's a typo!

umm. why do you flash unofficial cyanogenmod instead of lineageos?
Try flashing the latest roms, with latest twrp and see if it works or not. If it still doesn't, flash stock ROM and start again. I hope you have a backup made.

Help need please

Hi.. I have recently rooted my Samsung galaxy note 4 SM-N910F and I am wanting to downgrade from marshmallow 6.0.1 to Lollipop 5.1.1. I really need a dummy guide as I don't know how to do it and help will bbe appreciated
Hey there. Downgrading to an older version of Android means you'll have to factory wipe, but other than that it's pretty straightforward. Seeing as you have already rooted your phone, I assume you know how to use Odin, but here's all the steps anyway:
1. Download Odin
2. Find a Lollipop firmware for your device from SamMobile
3. Back up important data, and factory reset. You can do this in settings or in recovery.
4. Turn off your device, then hold power + vol down + home to put it in download mode
5. Open Odin, and put the firmware file you downloaded in the AP slot
6. Plug your phone in. If it isn't recognized, you probably don't have all the drivers installed - the easiest way to get those is to install Kies or SmartSwitch from Samsung.
7. Click Flash, and wait until it's done. Do not unplug the cable under any circumstance!
You're done!

Did you ask/search in the rom thread?
Maybe someone else had the same problem.
It could be a kernel issue, try other kernel.
I don't use a G but a C version, so I can't test to see.
Also consider the eMMC issue of the 910 SnapDragon, search about this.
Thanks for reply dear
Can i update or change kernel ?right now im on H-vitamin any other kernel can you suggest me is better then H-vitamin?thank for your support

Flashed roms stuck on bootscreen (logo screen)

Hi guys,
I need an advice. It will be appreciated!
I am with TRWP 3.1.0-1 alice.Flashed an image through official TRWP app.
I flashed "ressurection remix" , "stock 8.0" , "lineage OS". They all just get stuck on logo screen after install.I waited for 25 mins and nothing happens; only once the phone restarted & then froze again.
If i turn it off, after 4 secs. it turns on by itself.
(but if i go quickly with combo buttons, i am able to get into TRWP and go back to backed up system...)
I'm currently running Android 5.0.1 / EMUI 3.1 ;
I have rooted the phone with Kingoroot
(without pc)
***
If you can give some advice, i'll be very gratefull...
Thank you!
The best is you update your stockrom to emui 8 first, after this it should work with customs.
I see there are emui 8 updates, but they all seem to be for 2017 version.
I bought my phone in 2015.
Not sure if it is safe to flash something , that is for the later version.
What do you think?

As far as I know, Resurrection Remix, LineageOS, and all other Custom ROMs only work on B896 Version (this is meant for Vodafone). First, you need to have this ROM and only then you can successfully flash Custom ROMS, unless, you're searching for in P8Lite (2017)...
Do read the main part before installing... They should have mentioned it there...
