Which rom you're trying to flash?

Hello Mt.AK and thanks for your valuable help. I was trying with nitrogen os but its booting only when my phone is connected to PC otherwise bootloop, strange but true. . .I guess its kind of bug or what. . .?

[Q] ClockWorkmod Recovery bootloop

Hello guys,
I've got a bit of a problem.
I've got a Samsung Galaxy Young S6310n, with android 4.1.2
I recently tried to root it with CWM.
I went to the advanced menu, and fixed the permissions.
Now, my phone is stuck in a CWM bootloop.
I only have acces to my sd card.
How can I remove this bootloop?
Thanks in advance, Twitmuck

great that everything got normal...anyway this bug in CWM is annoying as using any feature from the advanced menu does this bug and using reboot to recovery will also do it....however i suggest you to use TWRP recovery as everything is working in it
Well, thanks for telling.
How were you able to fix it ?

Oneplus One LTE Issue

Dear All,
I don't know if I have posted it at the right place if I have not please guide me.
I tried my best to find a solution but couldn't that's why I am posting this.
So here I begin,
I am using OnePlus One from last 2 years and it is still working fine.
I have spent most of the time on Sultan's Rom which ran without any issues.
Recently I flashed [ROM][OFFICIAL][7.1.1_r9][BACON][OPTIMIZED]RESURRECTION REMIX [5.8.0] Rom and it worked well too.
But all of a sudden I started experiencing LTE signal drop.
I always do Nandroid backups so I restored to Sultan Rom but the problem was still there.
I have tried flashing modems with no luck.
Now I have started experiencing intermittent 3G signal too.
I have even tried restoring old KK backups but that doesn't resolve the problem.
This is so frustrating, Please help.
Let me know if more information is needed.

I'd do a complete clean restore of last official stock. If the issue still persists, it must be a hardware issue or an issue with your carrier.
If your device is wiped clean and stock software restored, there's no way it can be a software issue.
Good luck!

if clean flash through fastboot don't work out,try changing network antenna.
I don't think it's a carrier issue because it was perfect before.
The problem in network antenna must've been due to sudden drops or heavy impact.

Hi, thank you for replying.. Flashing stock ROM from fastboot is different than flashing it from twrp recovery?
Please let me know if it is.
I will certainly give it a try then.

Hi, thanks for replying... I will do a clean install, does it need to be done via fastboot or just recovery?
And do I need to wipe internal storage too?
Since fresh installs via recovery couldn't resolve the problem..

Flash stock Cos13 through fastboot,it will wipe your internal storage so take a backup.
Refer to guide "Bring your device back to stock Cos by Eddy".

Do you have 'unknown' baseband?? I was stuck on 3g due to that..
Issue Resolved
I dont know what happened, I had flashed stock cm13.1 via fastboot.
I checked and that didnt resolve the problem, so I had accepted the way things were and started using my 3g.
All of a sudden the 4g signal came this morning and now I can use LTE well.
I dont know how long it will stay but seems like phone decided to bring back 4g.

Bro, I am facing the exact same issue man. My LTE still doesn't work. I tried installing various modems. Still no use. I hope it does soon. :/

Im facing the excat same issue. Did everything and nothing worked. Somebody please help. :/
Bro try flashing stock cm13 via fastboot... That will wipe your internal storage but eventually bring back 4G
I am also facing network drop issue for last few weeks.at first i thought it may be rom's problem,because generally i try a new rom in every 2/3 weeks,but now i notice that ,i am facing the issue in all roms,i read all the comments in this threads and see that cm13.1 can solve my issue.but can i solve my issue within any nougat rom?
I too am having the issue. Occasionally my 3/4g data just cuts out but it is still enabled in settings. It seems to be when I come off of WiFi most of the time. I'm on CM13.1 by jgcaap.
I'm going to flash back to full stock and then reinstall TWRP, then the ROM. I have a few issues and I figured it was time for a fresh flash.

Are you talking about CyanogenMod 13?
I clean installed COS 13.1.2 via fast boot. It even removed TWRP and brought back Cyanogen recovery. The problem didn't resolve.
Can I install CyanogenMod 13 via fastboot now? or should I unlock bootloader, install TWRP and then install CyanogenMod 13 via fastboot? Please help. I'm a beginner.
In my opinion you should unlock bootloader and then reinstall via fastboot...

I'm right now on COS 13.1.2.
Lets say I install CM 13 via fastboot and my LTE works. Can I again revert back to COS 13.1.2 using fastboot without affecting LTE again?
Thanks for the help. I will try that this Sunday and Will tell you if it works.

N920c Keeps rebooting even after WholeFormat/new rom Dr Ketan Rom everything....

Hello everyone,
I tried to check in other threads and in forums in general but couldnt find a problem similar to mine , because all of them were fixed by Wiping/Formatting or installing a new Rom.
So the phone was ok stock 7.0 t'ill it started rebooting and stucking sometimes with no way to get out if it,if not resetting to Download mode. I wiped the cach and all and it seemed to work for a feew days, now its every time, i Flashed TWRP as a recovery, Wiped formatted vereything from the phone and did a fresh install o Dr Ketan Rom (even so it wasnt easy due to device random reboots).
Now the issue is still there, what have i missed? Is it a Hardware problem?
Thanks in advance .

You're asking for help in the wrong place.. This thread is for the N920V and not the N920C.. You're better off asking in that thread for help seeing as the N920V doesn't even have TWRP..

It's cool happens a lot.. The problem is us Verizon users don't really have much experience with the TWRP on this device so it's just best to ask where, they've probably had the problem before!! I hope you figure it out bro!

Screen lock was already changed, try again with the new screen lock

Hi,
After unlocking the bootloader with the latest official app, I cannot change the screen lock method of my Zenfone 6 with a message saying "Screen lock was already changed, try again with the new screen lock" and I can only choose "None" or "Swipe". The fingerprint breaks as a consequence because it relies on PIN/password/Gesture.
The phone comes with a fingerprint + password authentication before the unlocking, which seems to cause my issue due to mess-up of the TEE. Factory reset / Reflashing the whole image doesn't work.
Anyone experiencing similar issues? Is there any way to re-enable other unlocking methods?
Thanks!
Same happened to me,
I got back the pin option only when I relock the bootloader.
I used the official asus application, I'm gonna try the adb unlock option
Same thing here. Unlocking the bootloader breaks it. I fixed mine by flashing the downgrade to P zip, setting my phone all back up and then updating to Q. You might be able to just reflash Q and have it work, but if that fails go to P and then upgrade. Haven't had an issue since.
Did you downgrade to P being bootloader unlocked? If so , did you use the official asus method with their apk, or did you unlock with adb?
Thanks for your response !!!

I could never get the adb unlock method to work at all. I used the app to unlock, stayed unlocked and flashed back to Pie, then updated to Q

So, I am on a custom ROM, but I understand that you solved this on stock. Does anyone have experience how this can be solved on a custom ROM? Thanks!
Hey, I was having the same problem and tried doing several things without success (Like deleting files in the /data/misc/keystore, changing different ROMS, etc). What fixed it for me was restoring the vendor partition, the problem was that I removed the enforced encryption flag and that was causing problems with the GSIs I was installing.

how did you restore the vendor partition? did you use the backup on twrp or something? is there a flashable zip?
also did this happen after you unlocked or after you installed a custom ROM with encryption disabled?
Did you guys manage to fix it? I actually have the same problem with my Redmi 8A after flashing Magisk on Havoc and Stock ROM. I tried to delete the locksettings. db and .key files but i still can't set a pattern or PIN

Spot on !
Removing the .key and lockfiles from /data/system works !
I can set PIN again
....
Swipe TWRP on your phone, enter the system, and delete 2 locksettings....file in the DATA\ SYSTEM\ folder directory.. The file at the beginning can be successfully protected by restarting and setting a password or fingerprint.

I had trouble booting after updating as well. It would just stay on the boot animation forever. I had to clear dalvik and then it boot. Maybe give that a try?
Thank you for suggestions guys, finally solved my problem. Phone is working now. This thread fixed my problem,
