I have a first-gen Verizon Moto X running 4.4.4 that is rooted with an unlocked Bootloader via the Chinese Middleman method. I apologize if this thread has been asked before, but it has been a while since I've done any phone rooting/modification so I am quite rusty.
I have Xposed with GravityBox installed and my phone just downloaded the Verizon Android 5.1 OTA. Can anyone point to instructions on how I can safely install this OTA? I have TWRP recovery installed.
And to be sure, Xposed + GravityBox now works with Android 5.1 right?

I believe there is a new thread that addresses this basic situation. Sorry I don't have a link to the thread but its basically a guide to taking 5.1 update, you should be able to find it here in the General Section. Not sure how it varies for verizon but the basic Idea is you have to download the full firmware and reflash your system partition, gravitybox/xposed/ and any other system modifications won't allow you to take the OTA, and trying to disable/undo each thing is still risky. So you need to be stock basically, before you take it. And stock recovery as well.

I wouldn't bother to prepare yet. 5.1's not even entered soak testing for VZW's build. When you do get ready to prepare you basically need to flash back to a stock unrooted rom to accept the OTA.
The current OTA (212.166.3.en.US) on VZW appears to be just a minor bug fix (not 5.1). Probably this one: http://www.phonearena.com/news/Spec...-serious-problem-with-emergency-calls_id69001, but I haven't installed it yet.

Since you got your unlock code from the China seller... The First thing you'll want to do is read -> http://forum.xda-developers.com/moto-x/general/lollipop-warning-unlocked-via-sunshine-t3114428
Next, there is a pre-flash validation check that runs on EVERY OTA.. It checks certain parts/pieces of your phone. You can't deviate from what its looking for or the OTA will fail to install. Also, the only way the OTA will install is via STOCK recovery, if you have a 3rd party recovery (like TWRP) on your phone, you'll bootloop. Because of that you'll see suggestions to flash back to completely stock. While that is the easiest solution, it depends on your situation..
If all you did was Root, Xposed and Gravity box, no other changes to /system files, modems, etc... then you can disable Xposed (boot to TWRP and install /SDcard/Android/data/de.robv.android.xposed.installer/files/Xposed-Disable-Recovery.zip ) and you might as well uninstall it too. I'm not sure about gravity box. Then flash the STOCK Recovery.img for your stock rom on your phone using moto's fastboot.
Finally, There is a newer version Xposed for Lollipop. The old one only worked in Dalvik mode. Lollipop needs Xposed that runs in ART. But since I haven't kept up on Xposed, I'm not sure if there is a final or just an experimental version available now.
To confirm, I was able to flash it back to stock and accepted the OTA. However, like a previous user said, it was just a maintenance update and not the 5.1 Lollipop upgrade.
After a whole week of searching and tripping knox i finally done it:

After following this method I get a bootloop, any idea why and how to correct it?, already tried a factory reset but it doesn´t work, I had to flash stock rom again.
Edit: It happens because I upgraded to the latest 5.1.1 version available last week:
Model SM-G9208
Model name GALAXY S6
Country Taiwan
Version Android 5.1.1
Changelist 5683207
Build date Tue, 06 Oct 2015 11:54:52 +0000
Product code BRI
PDA G9208ZTU2COJ2
CSC G9208ZZT2COJ2
So if you get the update alert in your phone DON´T do it, there is no known way to ROOT this new version.
It was not possible to install a previous 5.1.1 version either (G9208ZTU1BOH2), when I try to flash it with ODIN, the phone just displays an error message “SW REV CHECK FAIL DEVICE 2 BINARY 1”.
Any Ideas are appreciated.
EDIT:
Finally rooted with xiao1u root method!

Root works perfectly, but has anybody got TWRP working on 5.1? I've always had unusable touchscreen issues on it so stayed back on 5.0.2 until somebody devs a working build.

The file on first post didn´t work, and 3 days after I rooted (and everything was working perfectly) using this file:
http://pan.baidu.com/wap/album/file...26914354&fsid=128909912720545&adapt=pc&fr=ftw
I get the following error message every time i need root access:
"There is no SU binary installed, and SuperSU cannot install it. This is problem! If you upgraded to Android 5.0, you will need to manually re-root - consult the relevant forums for your device!"
If the phone is restarted or turned off after getting this error message the phone is death, it doesn´t start again.
I tried reflashing the root file, but it didn´t work.
I had to reinstall the stock ROM agan, and waiting for any effective root method for 5.1.1 OJ2 ROM.

Not in my case, my data was working perfectly, but problems started to show up 3 days after I rooted it, in the end it didn´t start again.
I haven´t found any other way to root this build yet and I´m still looking for a custom rom with no success.
If you want to give another try to xiao1u file try to disable the setting for "allow Google to regularly check device activity for security problems or warn about potential harm" after a clean ROM install, you can do it going to the GOOGLE SETTINGS app > SECURITY > VERIFY APPS & uncheck Scan For Security Threats.
Please keep us updated, I´ll post if I find any way to solve it.

Ok you may know this already but I'll post just to let you everybody else know.
DONT UPDATE TO THE LATEST 5.1 OTA. It adds rollback protection to your bootloader, which makes it impossible for you to odin to another build, unless its the same or a future update.
http://forum.xda-developers.com/tmobile-galaxy-s6-edge/general/psa-odin-5-1-1-t3136151
As for our case, mate, I tried everything so far, the root method given by the OP bootloops on the latest OTA (previous 5.1 firmware on Sammobile is fine) and xiao1u method breaks mobile data for me although root does work perfectly. Funny thing is that if you tried the root by the OP and it got bricked, flashing the xiao1u method on top of it will get it working again, because its just the boot partition.
Atm, I just got sick of Samsung and their cr*p, had the same issues with my old Galaxy S4 with their Exynos. Got the Nexus 6P today and absolutely loving it.
I'll try to work it out sometime soon, if I do manage to get it working (mobile data for me) I'll post the fix here. This device is next to DOA for us as we've just got a couple of few blessed asian devs on it (all thanks to them). Unfortunately it may never be enough. I never got the issue you had, though it was just for last night, can you get into download mode? If so, odin the same firmware again. I used the 5.1 OTA on Sammobile, Taiwan. This is only for us who are already stuck in the new bootloader. You wont have root but at least your phone will work.
Cheers mate, all the best. Will update if I find a fix.

The results of my attempt to root is not very consistent or stable since 5.02 to 5.1.1 on different updates of the Taiwan variant (G9208).
Since first 5.1.1 update, I used xiaolu method and succeed for few days, I don't know what do you mean " xiao1u method breaks mobile data", my 4G signal was fine. With xposed hooked, I also observed the much more boot time of previous rooted phone, sometimes a smaller bootloop (3 or 4 repeated loops).
But after a very recent "samsung security policy update", the root has "gone" an re-root became impossible no matter by xiaolu's or chainfire UPDATE-SuperSU-v2.46, most time they will cause bootloop and I can use odin to get back to initial status. Does that mean I don't have hope to root again?

This works on my Taiwan variant G9208 on stock 5.1.1,
Go on TWRP repository of dl.twrp.me/zeroflte, seek two .tar files as below and inject them stepwisely with different method
1st (Odin via USB). Twrp-2.8.7.2-zeroflte.img.tar
2nd(use that TWRP -2.8.7.2, operate via an "OTG linked usb mouse" since touch not working...) . to flash Twrp-2.8.7.0-zerofltespr.img (but it's actually 2.8.7.1)
now you have a touchable TWRP.
But I can't get root now, even with xiaolu method, any one with luck, please note me

Hi guys!
I've been modding phones for about 4 years now, and its because of this community's work. You're better men than I, so thanks. I'm not up on the terminology (it seems to be inconsistently used) so if I refer to something wrong, please let me know. Here's my problem:
I'd like to update my firmware to the latest for a S5, but I don't know what I need. I've got a G900V, originally with OK3 (no updates aside from what is listed here). I rooted it back in April or so when that came out (thanks @jrukuse!), and I unlocked the bootloader yesterday by fooling it into Dev mode (thanks @GeTex!), adding TWRP 3.02. Today I threw CM13 on it, and just finished flashing the PF4 modem (just the modem), but it still shows the baseband as OK3. I've been getting weird crashes of some of the Google stuff (Gapps 6.01 micro), and I was hoping an update of some kind would increase stability somewhat. The problem is I don't know what needs to be updated or where to get it. As you can tell, I'm not even sure to what extent I actually still have things to update, why the baseband still reads as BOK3, or if it can be updated without losing Dev, root, or unlocked bootloader. Any insight on these last questions?
Thanks guys (and help me Obi-wan Kenobi, you're my only hope),

hi folks!
I am pretty confused now. I am looking to get the V20 H990DS, but i am more confused now after reading here. My questions:
1. Is Bootloader unlock possible?
2. Can i install TWRP?
3. Can i root?
4. There is LOS official i know, but is the problem with 2. screen now fixed / going to be fixed?
Seems so good of a device, but i am insecure about it now after reading here. My old Mi4/Cancro is one of the best supported phones out there, so i dont expect it to be the same with V20, but i need working LOS with Root and working 2. screen (or the outlook on it working in the future) to be confident in buying it.
I hope you forgive me my nood questions,
Greetings
With sadly no replys, let me add what i know now:
1. + 2. + 3. Still no easy way in sight AFAIK. EDIT: To be clear: There IS a way, Dirty Santa, but the instructions are somewhat too complicated to be confident with trying. Have had rooted Phones with custom ROMs since over 5 years and never again a stock device, but i dont dare it. The 300€ i payed are much to much to have spend it on a bricked device. Will try to find more dirty Santa noob friendly explanations and post them here. EDIT2: For those who DO dare it, here the thread: https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296
4. Second screen still a problem, nothing new heard for quite a long time.
Anyone with knowledge to add or correct, please help! Stock ROM is not as bad as i thought, but without Root, Android is not fully usable for me.
thank you pro for this thread
very useful for me.

i dont get about your complain. you said already using phone with root for 5 years so i guess you've been here on xda for a while. if you really want a phone which support custom rom go with phone which support unlock bootloader like HTC, Oneplus, or even xiaomy. its not that hard finding them on XDA. 300euro for briked devices? well, if you read v20 section carefully you knew most people here bought this devices for the camera, audio, and other things like removable battery, etc. i never found someone who bricked their devices while rooting here, even if they do we already had flasher tools like LG up which already tested fully working by some members. and whats the problem with second screen? its working for whatever it made for. are you expecting to watch movie on those 2.1 inch display? i had lg v20 h990ds rooted with magisk and had no problem so far. bought some apps like grenify and titanium backup for debloated and my phone rocking solid for abouth 2 month. if you cant wait for LOS just bought lenovo zuk2 or oneplus 3t on the same price range.
No problem doing 1+2+3 with DirtySanta exploit/procedure. It's not as complicated or dangerous as it might seem from the instructions. I thought I had soft-bricked my phone twice after rebooting normally with the old kernel instead of straight to TWRP to update the kernel first, but it was easy to re-flash the 10d factory firmware file I had and start over again without any issues both times.
Basic summary of procedure:
1. Flash factory firmware version earlier than 31 December 2016 (only needed if installed firmware version is after 1 January 2017).
2. Do DirtySanta exploit to unlock bootloader and install TWRP and root.
3. Use kdzwriter to update phone's system/modem/cust partitions to latest firmware version without overwriting unlocked bootloader/TWRP, reinstall root (SuperSU or Magisk) from TWRP.
4. Disable automatic OTA updates so that any future firmwares won't automatically install and overwrite bootloader/recovery and remove root and set ARB 1. If that ever happens then TWRP/root will probably be gone forever.
provided you follow the instructions carefully, it's safe to root with DirtySanta.

No, right now if you update you'll lose root as the engineering aboot isn't compatible with Oreo and you have possibly non working data, invalid sim issues etc

Too bad. Your earlier post actually got me excited. Hehe. Anyway, hopefully someones starts working on rooting the oreo firmware.
The short answer? @Stele88
Yes. To all of it.
The long answer starts with the Dirty Santa root process. Believe me, I was daunted by it as well, but as long as you follow it (or the noob version of the guide you can find by searching around the same section the original guide is in) and take your time, you'll be okay. It's what I did and I'm now where I am today.
I'll address a couple things since I have the same device as you. If you want to get your device working properly on LineageOS/ResurrectionRemix (LOS with more customisation) then it's a long process.
1. Start by following the bootloader unlock process for Dirty Santa. Depending on what firmware your device gets shipped with, you may need to downgrade to (in the case of the H990DS) the v10c firmware. Once done, then you can Dirty Santa the bootloader and get it unlocked.
2. Once that's done and you're rooted with the initial TWRP from the thread installed, you'll want to look into KDZWriter. It's a program by the same emdroidle who did the Dirty Santa process for us that allows you to update your STOCK system software to newer versions and keep root. You can use it for example with the H990DS firmware KDZ files and go from rooted 10c -> rooted 10f -> rooted 10xx -> etc. until you're on the latest available 7.0 KDZ for the H990DS. This will be the longest part of your process, but it ensures that everything is up to date before going to AOSP/Lineage/Resurrection, specifically the modem partition. I recommend using the TWN region of firmwares if you're just going to convert to a custom ROM anyway, but any region will work fine (the only real difference is that, for example, the Australia region of firmwares comes with more bloat than the TWN region).
2b. You can also use KDZWriter from an updated TWRP you can get in the thread by Phoenix591, his latest TWRP versions have KDZWriter built-in so you don't have to run it off the computer, you can do it all with the kdz files in recovery.
3. Yes, you can root using the Dirty Santa method on v10c kdz firmware. I recommend Magisk for root over SuperSU.
4. There's no official LineageOS that is as up to date as the unofficial ones, and there's no official ones with second screen enabled full stop. That being said, the unoffcial LineageOS 15.1 by x86cpu has been my rock solid daily driver for about 2 months now and I've never had any issues that stop me from using it. The same can be said for ResurrectionRemix 6.2 by Blaises. To use either of these, you will need the updated TWRP from Phoenix591.
4. Second-screen enabled builds of LineageOS and ResurrectionRemix do exist, and in this case ResurrectionRemix is (as of this post) more up-to-date than the LineageOS 15.1 second screen version. If you find yourself needing additional features that aren't in the stock kernels for those ROMs (such as KCAL configuration to help with burn in, among other things), then I maintain the second-screen version of the Gamma Kernel by Omar-Avelar. People are successfully using this with second-screen ROMs and have full functionality. You can purchase the app BoredSigns from the play-store to add additional functions to the second-screen.
As I said at the start, it is a long process, but a very worthwhile one. The jump from stock to custom-ROMs is absolutely incredible. Again, in short, yes. You can get everything you want.
Just do your searching around the forums for the processes I outlined above, ask any questions you have, pre-download your kdz firmwares from HERE and any software you need, and just take your time. It's maybe a couple hours to get setup with a rooted stock system that's up-to-date, and maybe another hour or so to go from stock to Lineage/Resurrection.
P.S: If all goes well with the Dirty Santa process, but you get screen distortion after rebooting when flashing the TWRP from Dirty Santa, just pull the battery instead of rebooting.
Good luck, good searching, and remember to not be afraid to ask questions in the relevant threads.

Too bad. Your earlier post actually got me excited. Hehe. Anyway, hopefully someones starts working on rooting the oreo firmware.

It's highly doubtful this will happen, but one can hope. Right now the best way to get Oreo is through a custom ROM, purely because of how security is implemented by LG in the stock Oreo ROMs.

Actually it is possible runningnak3d has already said awhile ago he has a process to root stock oreo he's just not releasing it yet so LG can't patch it before the Oreo roll out is complete
Sent from my LG-H910 using XDA Labs
So I bought this head unit and i am looking to root it. I'm accustomed to XDA and rooting and I also found the russian forum that disscusses these head units but I'm lost. It seems mine is newer(?) or more up to date than im seeing. It says android 10.1(it seems to be really 9) and is API 27.
Things i see seem to be giving root for my device but downgrading it. Is there any assistance I can receive on this? Attached some screenshots.

Okay so having the newer Android shouldn't be a problem as your unit type and MCU are right for modding.
I've successfully modded a similar unit only a couple of weeks back. Backup your current ROM by exporting the full memory dump, just in case of brick.
You start with installing TWRP recovery. Normally only version 3.0.2 will work. If not, try newer then older versions. One of them will stick.
After TWRP it's an easy ride. Install SuperSU v2.79 and if it doesn't work, try newer then older versions.
Now you can install Viper4Android. I suggest you stick to version 2.5.0.
Now just configure everything you need.
Ok thanks for the reply. I did some searching today on the forum after reading your post but all I see is flashing a whole new rom.
Is there a guide to just install TWRP to my current stock rom(I actually like it) and then the usual SuperSU to obtain root priveleges?

I just posted this this guide that provides custom firmware and lots of improvements to YT9216BJ, that includes TWRP, SuperSU and much much more. You can of course stick with the stock firmware but there is an option of making your unit much more appealing
