I've searched the forum and havent found a specific answer to my question. I am currently running 5.0 with the viper rom and its pretty damn sweet. my problem is a lot of my apps and some of the xposed modules wont work on lollipop but are compatible with KitKat. so obviously i want to go back.
is there any way to go back to kitkat without having to plug my M8 into a computer?? i would basically like to do it remotely and on demand, you know flash OS back and forth like you can do with a rom. can somebody help me out with the process if it is at all possible.
You should be able to run a KK version of Viper (or other ROM) with Lollipop firmware, as least from what I've read from reports by others. While old firmware causes problems with current ROMs; the opposite has been found to be a a different matter: firmware has been found to usually be backwards compatible.
You can always make a TWRP backup of your current setup. Then try a KK ROM, and if you have issues, just restore back to LP.
If you do run into issues, then you probably do need to downgrade your firmware to KK (need s-off to downgrade firmware; and not sure if there is a computer-free way to flash back to KK firmware).

So...
I got the tablet coming up on a year ago, and I rooted and installed TWRP immediately.
I'm currently running a stock ROM, and would like to continue to run stock based roms, but I've had issues with the custom kernel I'm running. The skyhigh thread is meager when it comes to details, but it also includes a few cryptic warnings about base and source and boot loader. Because I have no idea which one I'm running, or what to flash in TWRP, I'm in a terrible spot.
Searches, P.M.s and thread posts haven't gotten me anywhere.
Even if I could use Odin, the stock firmware thread, and the TW-Based ROM threads don't include the requirements, how you can test to see if you meet them, and if you don't, how you'd go about letting the requirements for base, etc.
Because of the introduction of threads like the stock firmware thread early on, root and odin methods used obscure FW, and now when selecting a few to download you have to choose between FW from France....from no country at all, or from the made up country of Us Cellular. So again, even if I wanted to broach the idea of Odin back to some semblance of stock, I couldn't.
But I ****desperately need a reflash/wipe/update***
Id like to run ironrom and kernel....
So how would I get there....from here? And preferably with TWRP?
Rooted 5.0.2 with TWRP and a really really old version of sky high.

I'm also interested in this answer. The only reason I haven't updated to (any ART) rom is because I'm unsure if I can just restore a Dalvik backup without issues. The only way I would attempt is with TWRP.
i tried doing by Flash tool and it gives error like 0000008
bring up the post!
Curious as well. I'd like to get root.
Windows user not sure how to do it on Mac/Linux
by MM to KK I assume you want to take the LG G3 D851 from android 6.x down to 4.x
here goes...
----
http://lgg3root.com/lg-g3-stock-factory-firmware/
http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
use the LG Flash tool plus the two files, follow instructions on that second link step by step.
LGD851_20140611_LGFLASHv160.dll
LGD851AT-01-V10c-310-260-JUN-20-2014+0.tot
That takes you back to the 4.x kitkat stock ROM, not rooted or anything.
----------------
To go north from there back towards Lollipop or MM you can at this point use
http://www.download3k.com/Install-LG-Mobile-Support-Tool.html
B2CAppSetup.exe
Install it, will put an icon on your desktop, plug in your phone, open the app.
It's pretty much automatic, it updates the ROM from KK to Lolli, then if you hit "OK" it will update from Lolli to MM
- I just got both of these steps to work in the last 24 hours.
I'm still trying to find a valid "Root" method that doesn't ask me to install a funky ROM.
I went from a KK stock-rooted(TWRP 3.0) rom to the MM 6.0 Rom, realized I didn't really want to set everything up again, restored my KK backup. Only problem was I had to reflash the modem. That was a couple of days ago and the modem was the only issue.
I'm unsure about flashing a new/clean KK rom over a MM rom though.

I think I missed a step, in KitKat this phone needs a special command thrown at it so the memory cards will be read/write.
On the play store SDFix: KitKat Writeable MicroSD
I think that might be what I was missing last weekend. My phone is currently on MM but I can't root it with any method other than Kingroot and Kingroot is Bad News.
Yes. It's possible!.
Hi,
After doing some reading on here I am a little unsure on the best way to back up my HTC One M9 (GSM) stock recovery/system. My software number is 3.50.710.1 (Android 6.0) and it came from Optus (Australia). I cannot seem to find an RUU file for this firmware anywhere online; only earlier versions are available. My understanding of this is that I need an RUU file for my specific firmware as a fail-safe in case I mess something up and need to return to stock?
My questions are:
1) Can I get my phone back to the current complete stock firmware and be able to receive future OTA updates without turning s-off and without copying anything from my phone before I flash TWRP and a custom ROM?
2) If not is there anyway that I can back up my phone it its current stock state that will allow me to go back to this state if I want to go back to my stock Optus firmware or to install OTA updates? (Including the stock radio/recovery)
3) Reading this post as well as others leads me to believe that I may stop my mobile radio working by flashing a custom ROM (especially as the linked post has the exact same firmware as me). How can I avoid this, or fix it if it happens to everyone?
I am ideally looking for a custom ROM which improves over the stock firmware. My priority is maximum battery life, with customisation and HTC 10 system UI/apps a secondary focus. Any recommendations would be great, as well as tweaks and kernels which help give the maximum battery life.
Cheers!
You can't backup your firmware (and that includes your radio). However if you read my google sheet you'll find instructions for backing up your current boot.img, your system and the stock recovery. If you do it correctly those files will suffice for recovering the ability of installing OTAs. No personal data will be backed up so maybe you want to share your backup with us afterwards.
There is a custom kernel for CM/AOSP roms which is said to repair the signal problems. As far as I read some sense rom users reported that flashing the stock boot.img recovered their signal. However this doesn't seem to work for every user. So you'll need to try by yourself.

Thank you so much! I have managed to find the guide you mentioned to backup the stock boot image, system image and recovery. By the looks of it the tab to the right is the guide to return my phone to its original state, which is good. I'm more than happy to share the backup once I do it.

Okay, well I am planning on keeping s-on at this stage, so I'm left with Sense based ROMs I believe? I have read that LeeDroid is the best for battery life, does this sound right? If so I am unsure if I can flash it as it says "Please make sure you have the latest HTC Hima 3.35.XXX.XX Marshmallow firmware installed prior to installing this ROM" because my software number is 3.50.710.1?
Thanks again!

I've read that several times in the near past and I actually don't understand it. You never needed S-OFF for flashing none-sense based roms as long as I started using Android/HTC phones and that was back in 2012. Why do so many people think they need S-OFF for AOSP?
I personally prefer the Viper rom. But taste differs and in the end the best advice I can give is try it out by yourself. Everyone has different needs and is using his/her phone in a different way. The best rom for person a might be an awful choice for person b since he/she has completely different needs.
I can't tell you whether you can use Leedroid. Test it and report back. That's how xda works. You might be able to use it after you flashed your stock boot.img but I don't know whether you really are or not. The warning is written so that people don't start flashing that rom with a lower firmware version. On older HTC phones flashing an "older" rom has never been an issue on newer firmware versions whereas flashing a newer rom on an older firmware never goes well (even on the M9). However many things have changed since the M9. There is no hboot anymore, the Download Mode got introduced, google changed the way OTAs are checking whether your system is modified, and so on. (Just to mention a few changes.) Those issues with the lost signal didn't even exist on pre-3.x firmware versions of the M9. Therefore users like you who use a not so common firmware (in comparison to the user numbers of the most common firmware bases: international, taiwanese and the developer firmware) have no other choice but trying out by themselves or getting S-OFF and changing to a more common firmware.

I have followed your guide and now have the latest stable LeeDroid ROM installed and TWRP. Just as I predicted the radio was not originally working. When I restored my stock boot.img from the original backup I performed it began to work. Thanks so much for your help! I'll upload the backup to cloud storage when I get access to a decent internet connection and then I'll share it to help others out.
Hello!
I have a friend who is fed up with Lollipop, downgraded to KitKat and is still having issues, so now he wants to downgrade the Note 3 back to Android 4.3 (Jelly Bean), but the ODIN process keeps failing. I've read around that downgrading the bootloader (to a version prior to the KitKat update) would bypass the "Must be a KitKat ROM" check and allow his device to be downgraded to the older firmware, so my question for you guys is could you please provide me (or at the very least) point me in the right direction so I can successfully complete this for him? If it's absolutely NOT possible, please let me know, but based on my reading around on XDA, I'm pretty sure it's possible once you downgrade the bootloader to one which doesn't include those checks.
Thanks.
You cannot load a 4.3 bootloader over a KK or LP bootloader.
Your only option is to flash a custom ROM based on JB, but at this point in time I highly doubt that any links to JB are still functional. As stated above, you cannot load a 4.3 bootloader once you've updated to LL.
What are the so fed up with on 5.0? Mine has been a dream especially with all the recent little updates. Buttery smooth, and no issues at all. Maybe a full factory reset, or even a factory reset, and ODIN flash of it again? Sorry to hear about the problems.
Hello I'm currently running 4.4.2 with root and I've been thinking about upgrading to marshmallow. I just wanted to know whats the best way going about it. I'm assuming that I'm going to have to re-enable the software updating app that I disabled for I didn't get OEM updates then upgrade to marshmallow and re-root using one of the guides or would a root keeping app or Survival mode on superSU possibly work? I also believe I have TWRP installed from when I rooted my phone before, I'm not sure if that's important info. Also side note, would their be a way to keep the 4.4.2 touch buttons on the bottom of the screen? They make more sense to me then the new ones. Device info below
AT&T
android 4.4.2
software version D85010d
Model number LG-D850
You can't root on marshmallow so if you want root DO NOT update with that app. the easiest way is to just flash a rom. i have the verizon version (vs985) and all i have to do to flash a custom stock rom, is to flash the right modem before flashing the rom, then flashing modem again after the rom and bam, i just flashed a marshmallow rom from kitkat 4.4.2. you can also downgrade that way just flashing the appropriate modem before and after and bam.! but i dont know about your version, you should definitely check the att&t G3 subforum. you need to be careful and read thoroughly so you don't brick. the thing with vs985 is that there are modems out there that can hardbrick the device, however, it may not be the same for others but, just in case you should read.
Thank you I'll look into that. So far I found this https://forum.xda-developers.com/att-lg-g3/development/rom-stock-bumped-marshmallow-v30a-t3661194 but I still got more research to do since I'm unfamiliar with flashing modems and whatever "bumped" is exactly. Hopefully this weekend I'll have more time to look into this.
