How to root LG STYLUS 2???
Hi,
once i tried to root this (LG STYLUS 2) device by KINGOROOT app, It succeeded and I installed some Root need applications too like Titanium backup and Root explorer so it was completely root, but after all when I restarted the device it could not boot again and I had a bootloop problem and I installed a stock rom again using LG FLASH TOOL to fix that , so is there anybody here that have rooted this device whithout any problems.

Yes. I rooted it once with Kingroot. However on reboot you have to fix root permissions again. Just run Kingroot again and it will reroot the device. This with a LG-K520DY. BUT....
I must warn you that once rooted you can never clean the system of the root files. Even if you unroot the phone with Kingroot software, the system is not clean and you cannot get OTA updates. I did fix this problem by downloading LG Bridge from the LG support site and updating that way. I now have an unrooted phone and I don't recommend rooting this particular model because of all the difficulties LG has created around it.
This is same phone as stylo2 there is a zv3 kdz file there in android forum the zv3 is can get root and full root after some work

You can S-Off and Super CID your phone from your nearest HTC servicing shop for about 5-10$ (for me, it took nearly 6.5$) by 'xtc2clip' or you can use 'Sunshine S-Off' app for android which costs 25$.
And to downgrade, you'll need 5.0.2 Firmware files which are locked while phone under S-ON mode. i have these firmware files, if you need these files, i'll upload these files here
Good luck!

Can you explain the procedure to downgrade step by step?
I am S-OFF & CID:11111111 (owner of xct2clip), but everytime I have tried to downgrade (via RUU or fastboot flash 0PFJIMG.zip) , I have failed miserably. I have tried relocked bootloader, unlocked bootloader, new HTC drivers & fastboot.......
I was able to restore a lollipop TWRP backup, but that doesn't downgrade the baseband, hence I still get reboots & bootloops when on the cyanogen rom
So which exact stock firmware files & procedure did you use to downgrade?

Fingerprint sensor stopped working after unbricking my XT1650-03.

I suffered from a hardbrick when locking my bootloader. managed to install the Stock firmware with December 2017 updates. (Software channel retca) phone finally came alive after 3 days working on it but the fingerprint scanner seemed to have disappeared. Any ideas why and how to fix it?
i have the same problem too! i've tried to install stock and custom rom but still, no luck . If anyone here know how to make the fingerprint scanner works again, kudos to you!
I managed to do the bootloader lock again, however, then I ran out of operator, but I unlocked the bootloader and installed a custom rom and everything is functional.

@erfanoabdi do you know any solution for our problem?
Did anyone find a solution yet?
I was finding out that several MOTO G4 PLUS users had the same problem, because it is an error in the HW partition error that was solved thanks to a user who uploaded a copy of his partition without errors, sorry for my English and for not knowing much of the subject, I feel that based on this we can solve our lack of fingerprint sensor since several users of moto z have the same problem.
I attach the link, the important information goes from page 10 onwards, in the YouTube video you see how the own partition is arranged based on the partition without errors uploaded by the user
https://forum.xda-developers.com/mo...luss-model-changed-to-g4-lost-t3496912/page10
https://www.youtube.com/watch?v=o2Pao6lnINg
I trust that one of you will help us with the copy of the hw partition which can be done with partitions backup & restore apk

You must flash the persist partition with twrp. You can find a tutorial at the 4pda site
I am having the same problem.. any solution??
Thanks in Advanced..
I read on a latin facebook page, that you need to install some rom, the majority agrees with miui 11 to start it, to activate the usb depuration and to install the global and european stock android one 9.0 rom and that the problem is corrected, i do not correct why the process has to be that.

So basically, i updated to stock android 10, realised it was a mistake, flashed stock 9 via fastboot, lost sensors, installed orangefox rexovery and flashed latest PE, while in PE i tested the sensors and they were fully working, flashed stock 9 via fastboot again and everything is fine now. That was it.
Every time The same story. Before the update every user want it like a question of life or death. After ask how to downgrade. LoL

Strange, i've used the method twice now with success. Are you using the official march fastboot rom from xiaomi and the latest platform tools?
Sapper Morton said:
@sioneng @eltonb
You guys are missing an important step; for the downgrade to be successfully done, you must come from a custom Android 10 ROM for Pie vendor, as such only the official PX is eligible, not the unofficial by nullby, because the latter uses Stock 10 firmware, vendor included.
I suspect it's because dtbo.img, since it carries hardware information to the Linux Kernel, thus the sensors would be targeted.
You can use any custom ROM that matches the requirements, as such the EvolutionX by chaplindev; but I do recommend to use PX Official build, just because that's what I used to recover my sensors back; download is available here.

That's the one i used both times and successfully restored the sensors..
Solved
Just Download laurel_sprout_global_images_V10.3.4.0 This Rom and Flash .....I think everything will work fine.
When i tried others like v10.3.16.0... Also facing same issue.
