Hi All

I tryed flashing my rom on qtek 8200 !!

Unfortunately it was a rom for the 8100 insted. so now there is only white screen when its turned on..

Is there any way to restore the bootloader from a memorycard ??

Regards NPG
[HTC Hurricane] dskid807:
The only way is via JTAG points and I have heard that they are shielded by a metal cover.

I am using a JBL headset with single button to answer calls. The problem is the button is functional for roughly 15 seconds after plugging in and does nothing after that.I can play/skip music in this time span only.The buttons works once again if I replug it.The headset works normally in other phones.Currenly I am in nougat.The problem is persistent since marshmallow..Thanks in advance

[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] jacoghi:
This is a beta, working build of LineageOS 14.1 for markw, Xiaomi Redmi 4 Prime. As many here already know, I had a problem with my phone while developing this, my USB port snapped out of place, so I can't continue development at this moment. Actually, only will be able to fully resume it when I can get my hands on a new phone / fix mine, which is something ongoing. Anyways, through the help of many members from this forum, we were able to make sure the basic rom works, so people can have a taste of Nougat, if they can live with the compromises. Source is also coming up, so other people hopefully can fix what was left broken during my time procrastinating from developing ;). No fancy announcements,

JUST READ

to make sure you understand everything

BEFORE INSTALLING!

What works: Everything, except,

- Camcorder in Snap (use another camera application to record videos - Stills work just fine);

- Fingerprint;

IMPORTANT INFORMATION (READ THIS SECTION 7 TIMES, AT LEAST, BEFORE POSTING ANY LUDICROUS QUESTIONS):

- Rom is based on stock 8.2.4.0, therefore

ADVANCED REBOOT ONLY WORKS WITH 8.2.4.0 BOOTLOADER!

- BE AWARE THAT HW ENCRYPTION FROM 7.1 DIFFERS FROM 6.0 (WHICH OUR RECOVERY IS BASED ON), THEREFORE,

IF YOU HAVE AN ENCRYPTED STORAGE

AND BOOT UP THIS ROM, YOUR RECOVERY WON'T BE ABLE TO READ INTERNAL STORAGE ANYMORE! THIS CAN BE FIXED BY FLASHING A 7.1 BASED RECOVERY (WHICH I WILL COMPILE, BUT NEED TESTERS, SINCE I CAN'T DO IT MYSELF) OR SIMPLY BY HAVING AN NON ENCRYPTED STORAGE (See Guide by @Modest Mind - https://xdaforums.com/redmi-4-prime/how-to/redmi-4-prime-pro-markw-how-to-disable-t3594239). THEREFORE: I STRONGLY SUGGEST ONLY PEOPLE WITH NON ENCRYPTED STORAGE TO FLASH THIS. NO QUESTIONS ABOUT THIS, THINGS ARE DIFFERENT, SIMPLE AS THAT!

- Flash it normally (Rom + Su addon for 14.1, arm64, GAPPS). Reboot to ROM.

That's it for now

17.06.14

It would be useful to indicate the procedure for installing 14.1. For example:

Reboot to recovery

Wipe system, cache, dalvik / art cache, date

Flash rom zip and gapps

Reboot

Regarding the YouTube bug:

This has to be one the weirdest bug I've ever seen, some videos for whatever reason DO play, while others simply show black and only sound plays. This has nothing to do with the time of publication of the video like it was mentioned in some other comment, to me it just looks completely random. :eek:

Do you think it would be possible to integrate the latest kernel 3.18.57? There are a number of patches and enhancements for the armv8 architecture and others.

I gets this pused phone after a few days in a few days. Is it possible to use F2FS with this ROM?

Using opengapps pico, official youtube (from playstore not opengapps) and og youtube (magisk module) display blank when viewing video but audio worka fine, no problem when playing youtube video via browser.

Likely codec problem, in marshmallow there are option to use nu/awesome player in dev option that sometimes helped with video issue.

[MENTION=4929139]dels07[/MENTION], the videos always use the same codec regardless of where it is being played, so if it works in the browser, the rom has all the necessary codecs. Must be a dependency of this updated YouTube app that we are missing, can anybody grab me a log?

Battery should be flat at night(sleep), if it is not this is battery drain.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] asfethan:
I was working over night at weekend (datacenter migration if you are interested). That's the first point. The second one is that if you don't disable wireless connections (bluetooth, wifi, gsm) there is and there will be battery drain because of gsm communication with near celltowers (you have to be registered within them to use gsm network - receive/make calls, etc), wifi communication with near AP and also bluetooth communication with your paired devices (my garmin watches in this case).

Actually I have problem with indicator maybe? If I put phone on charger and disconnect it when it shows 100% there seems to be huge power drain. I have to charge over 4-5 hours to get standby time over 3 days. So I don't know if there is problem with charging or battery/charging indicator.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] dels07:
Already try battery calibration?

https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device#without-root

It's not to extend your battery life, but to fix the indicator... Fully discharging battery is bad so do that only when you need (once in 3 month).
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] FelixDB:
True but the time it is waked versus the time it is in sleep should be minimal. If power management is well optimized and your ROM/apps dont wake for too long before sleeping again it should be almost flat.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] gGonzOfficial:
Don't flash this if you have goodix. The gx_fpd service won't start due to missing SELinux policy and it will be trying to respawn forever, draining your battery, unless you stop the service manually with adb as root.
