[How-To][Tutorial] Downgrade Kit Kat 4.4.2 to JB 4.1.2

Hi,
I am just writing these steps to help those who want to downgrade from KK to JB due to any reason. Please use these steps at your own risk.
Some Background:
Recently I updated my Razr M to KK, it was Locked and Unrooted, but with the help of Twelroot and Motopocalypse I rooted and unlocked the BL.
Now somehow I didn't like the KK and wanted to go back to JB 4.1.2 because I was now having unlocked BL and rooted phone so it was easy but need to follow some steps to successfully downgrade to JB. So an unlocked BL and rooted with KK is must.
Prerequisite:
USB drivers for Razr M must be installed before proceeding.
Steps:
1. download the firmware file [Android 4.1.2
Blur_Version.98.30.1.XT907.Verizon.en.US] from http://sbf.droid-developers.org/phone.php?device=8
2. extract the above archive and replace the XML file with the one in attachment.
3. put the phone into fastboot mode and flash the firmware with RSD Lite (attached)
4. reboot and now you have JB 4.1.2
If you want to install root application again and also want to flash custom recovery then please follow the Post#5 [ATTACK] (thanks ATTACK)
Note : for custom recovery you will need the fastboot.exe if you don't have it then install minimal_adb_fastboot_v1.1.3_setup.exe(attached).
Put the phone in fastboot mode, copy the recovery to c:\ and execute the below command :
fastboot flash recovery [Path to recovery image]
If it help you then don't forget to press Thanks button !

Forgive my ignorance but this won't downgrade the kernel will it? I'm hoping it's possible to go from the newest OTA to the stable CM11 but I'm guessing this is new kernel JB. Either way thanks if I can't go to stable CM11 I'll stick with rooted 4.1.2.

Once you have a unlocked bootloader, you do not need to use "root programs". All you need to do is flash a custom recovery via Mfastboot / fastboot then flash SuperSU / Superuser.
In dhacker29's folder there are 2 different recoveries.
"msm8960" is for 4.1.2
"KITKAT" is for 4.4.2

Could you go back to KK when you've downgraded to JB? Just asking this question early before the CM11 M8 release and the transition occurs.

So just by flashing the KK firmware in RSD without any changes to the xml? Sorry for the noob questions, I realize how easy this phone can be bricked and I want to avoid it.

I see don't why you would need to. It would be just like restoring stock firmware via RSD Lite.

Can you please post the error that is displayed in RSD Lite ?
The steps are tested by my 2 times, and there shouldn't be any problem. Make sure you have installed the correct drivers.
Please ensure that your bootloader is unlocked and shows BL unlocked status code 3 on BL screen.

I was also able to successfully flash back to JB with House of Moto via fast boot and full data wipe. It would not work with Universal or Keep Data, had to do full data wipe. Just another alternative :good:

Thanks You Its a Success Downgrade From 4.4 stock > CM11 > Stock rom 4.1 Thank you so much !!!

For those undergoing the downgrade process in RSD Lite and it takes forever for it to finish and the system ends up without data/signal, you need to RSD Lite flash again in order to regain signal. I believe the flashing was sluggish due to the jump from 4.4.2 to 4.1.2 and the many changes that were reflashed.

We have a wiener!
Thank you so much for the guide. After a lot of trial and error (mostly error), I thought that I had bricked my lovely XT907. I finally restored KitKat by flashing the 4.4.2 firmware with the edited XML file (deleting lines with "Getvar", "var" and "oem" in them), then followed your guide to the letter and found myself with a perfectly functional phone once again. No more sticky fastboot loops or audio-related crashes for me!
Lovely guide - thanks again! :laugh:

[Stock Rom] KVT49L.D85110r [Flashable Zip]

I have created a stock, flashable zip of the latest OTA. This is UNROOTED, but can be easily rooted using the SuperSU Flashable zip found HERE! This will not update your modem or bootloader. This is simply the updated boot.img and system.img. I will add more to this and clean it up when I have more time.
Download:
D85110R.zip
Here is a flashable zip for the 10R modem. - Thanks to @graig79 for the update.zip and @autoprime for the modem.img
If you would like to update to the additional 10R Bootloader/Firmware here is a flashable zip courtesy of @autoprime. This is not a locked bootloader and is safe to flash. This will flash aboot.img, dbi.img, factory.img, laf.img, rpm.img, sbl1.img, and tz.img from the 10R release.
Installation Instructions:
Clean install:
Wipe Data/System/Cache/Dalvik in either TWRP or Philz
Flash Rom
Reboot
Dirty install from 10M or 10C Stock Roms (Installing this over other custom roms may cause issues)
Wipe Cache/Dalvik in either TWRP or Philz
Flash Rom
Reboot
Standard Disclaimer: I am not responsible if this blows up your phone or sdcard. You should know what you are doing or read up before flashing. I have installed this myself without issue. If you have issues, read up and search before saying there is a problem with the rom.
Credits:
@zone23 for the updater-script
LG for the update
@autoprime for the boot.img

Thanks bud!!! Have you run across a legit changelog for this update (beyond what tmo is willingly telling us)???
This is what tmo posted for anyone interested...
New features
T-Mobile Free Inflight Texting support
Improvements
Bluetooth connectivity improvements
Wi-Fi connectivity improvements
UI improvements for T-Mobile Free Inflight Texting suport

Thanks for the upload doc

So I have a rooted version that has been deodexed, added a few tweaks, debloated, init.d support, updated all core apps, and added busybox. I will test it today and if all goes well, I will upload. When I say debloated, I mean like 958mb. Thing should run like a champ.

That would be awesome!!

Has anyone been able to take this update via OTA or using the LG PC Suite software?? I tried using the PC Suite software and am getting this error "Cannot Proceed Upgrade: Mobile device software upgrade is blocking on no upgrade policy". This is even on a brand new phone that I just got from the T-Mobile store today!!

Thank you for this. I dirty flashed the update, modem and supersu and all went well. Not that I want it but is the 10r bootloader locked?

Couldnt tell you what you did wrong. This is just a flashable stock rom so there should not be anything else that you need to do. I would start with checking the md5 on your downloads to make sure you did not get a bad download of either file.

I am curious aswell but from what the OP/common logic(not trying to be sarcastic/mean) states
It should allow you to flash the both because rthe boot loader is alrrady unlocked(may overwrite your twrp but installing that is pretty simple) and the modem doesn't even handle that part if the software, I'm flashing all of them now so I'll post if anything happens
EDIT: it kept TWRP but the zips need to be flashed in the order of:
MODEM
BOOTLOADER
ROM
the bootloader fails if it it has the incorrect MODEM underneath it
also i got a boot loop on the rom
EDIT2: its been so long since i flashed a rom, i forgot you needed to wipe data lol

This does not touch the recovery partition so twrp will not be touched. Since this bootloader is still unlocked, there is no harm in flashing. Especially if you are running 10r modem/ROM. Won't hurt if you are running aosp either.

@krowley3 Can I dirty flash this over stock 10m? Obviously I'm rooted I would need to flash the superuser.

I noticed that I after I flashed the new modem and the new bootloader I lost the HD Voice? Does anyone have this issue?

dirty flashing D85110R.zip over stock 10m experiences
Thanks for the post and files krowley3!
I was considering a dirty flash of D85110R.zip over my rooted Stock "m" build as I see that the OP has instructions for doing so...
From OP:
Dirty install from 10M or 10C Stock Roms (Installing this over other custom roms may cause issues)
Wipe Cache/Dalvik in either TWRP or Philz
Flash Rom
Reboot
I was just looking for some feedback from any members who have dirty flashed the D85110R.zip?
TIA

I have all 3 zips in the OP, plus the SuperSU zip. is there any order i need to do this in? I have rooted 10m, so i was just gonna wipe dalvik and cache and install the zips. Should i reboot after each zip? Thanks

[BOOTLOADER] Bootloader Unlocker/Locker from recovery

Hi guys
Bootloader unlockers/lockers from recovery are here.
Easy method to unlock & relock Optimus G bootloader.​
Good things about these zips:
1. No running OS is needed.
2. You don't have to be on lg stock roms.
3. Work much faster & easier. Less than a minute.
4. You will still have custom recovery after locking your bl.
How to use?
Using bumped recovery, flash them like other zips in recovery.
Don't have recovery?
Flash a bumped recovery img (inside of the attached zips) with an app like Flashify or Kernel Adiutor or etc.
Note: BL unlockers flash unlocked bootloader + Philz/CWM recovery. Booting up on unlocked BL needs unlocked kernel.
So in stock roms, don't forget to flash an unlocked kernel, like unlocked stock kernel or solid kernel or etc...
Anyway in case of any problem, there is no worry because you can always access to Philz touch(for E975) or CWM(for other variants) recovery.
I could only test E975 ones. Other variants unlockers must also work. But you are the testers...
Mirror links (files folder):
https://mega.nz/#F!4JwWCJZB!3jFrgKSdRhAhdwLadD_YaQ

Please Note:
1. I'm waiting for your feedbacks. Please give feedback with name of your variants.
2. I didn't have stock bootloader files for other variants, so I could make bootloader locker for E975 only.
Some guides:
1. How to flash boot/recovery .img in Kernel Auditor?
In the Backup section of the app, use Flash IMG button, then select your .img file (extract them from zips), then select the partition to flash (boot/recovery).
2. You can use your own bumped recovery img, using the bump tool
3. On locked bootloader you can enter to recovery with hardreset method.
4. After flashing Makoz30f Flasher (not after unlocking, unlocking is ok), it will also flash bootloader tz.img & rpm.img.
Flashing Mako rpm.img will cause false heat issue on LG roms so your screen brightness will not go further than 63%(& cpu clock speed further than 1188000). E975 unlocker & relocker zips will replace tz & rpm partitions with stock ones. So you can use them to fix this problem.

Whats mean stockboot?
Btw thanks, no instal freegee to unlock bl , nice job

for other variants of og, after unlocking, you need to flash an unlocked kernel, but for E975, if you use the zip that has stockboot, you dont need to do anything & it flashes the kernel for you.

MMK instruction
Hi MMK,
I'm a total newbie and it's the first time i've ever flashed a device, my E975 is completely stock (but i've root privilege and su is installed). I've installed flashify and downloaded a zip (i don't have a special kernel at the moment do you suggest stockboot). Now i've unzipped the folder on the phone but i'm uncertain about what to do now, there are a lot of images and i really don't know where to flash what. Can you suggest a more detailed procedure?
Thank you for the effort and thanks in advance.

great job bro ^_^

Hi, If your bootloader isn't already unlocked:
In flashify you must choose recovery image from flash section, then choose the Philz.recovery.img you've extracted.
Then press reboot to recovery from options & simply flash the zips in recovery mode to lock or unlock your bootloader.
Make sure to use your own variant zip.

If you want stock based roms like Sling Kahroba,
Before unlocking, flash a bumped recovery & install the bumped Sling Kahroba... Easy.
PS: you can't use lockers because they're only for E975 variant.

Hi
I reverted to Lollipop from MM on my G3. If you are rooted and have TWRP installed you need to use TWRP to reset the phone, system, cache etc and SD card (internal) and then use Flash Tool 2014 and

Try this from the link....hope it helps

Root the phone, format then flash stock ROM you downloaded onto the external SD. But, why would you want to. I think 6.0 is the Windows 7 of Android. If you have that you will be in the loop with incremental updates rather than being stuck with what the ROM has.

[GUIDE] [HOW-TO] Downgrade to 5.1.1 lolipop

So......first of all lets clear something out: nougat is fine. marshmallow is fine. even the first firmware that was ever released on the s6e+ was fine. But if for whatever reason you would want to downgrade to lolipop heres how:
WHAT YOU ARE ABOUT TO DIVE INTO INVOLVES HARDCORE BOOTLOADER MODS AND FLASHING SAMSUNG ENGINEERING FILES. PROCEED AT YOUR OWN RISK. NO ONE (INCLUDING ME) WILL BE RESPONSIBLE FOR ANY DAMAGE TO YOUR OWN PHONE.
So......downgrading to lolipop...... some ppl claimed it can be done by deleting some file in the odin .tar but that never worked for me.
If you have the sw rev check fail error upon downgrading....this is the guide for you
This will wipe all your data including internal storage (depending on how you do it)
Confirmed working on 2 g928f devices (one of em is mine) should* work on g928c but cant make any promises
disadvantages:
1. You cannot boot twrp while on the downgraded bootloader (still working on that tho)
2. You will only have system-wide root. DO NOT flash systemless or it will not boot (also rip safetynet)
3. Fingerprint is not working (still working on that)
4. You can only flash stock nougat or stock marshmallow from odin. You cannot flash lolipop tar,twrp tar,cf auto root tar or anything else
Instructions:
1. Wipe /data /system and /cache in twrp
2. Download this lolipop rom i cooked up in a few mins or any other lolipop rom (but this is tested as working w this method) and flash it (dont mind the supersu flash in the rom. it doesnt work. flash this supersu)
3. Download and flash this supersu (optional)(depends if u want root)
4. FLASH ALL OTHER MODS NOW BCUZ U CANT BOOT IN TWRP BACK LATER
you can try to boot but it wont. You need a bootloader
5. reboot in download mode and flash this modified bootloader
6. boot in stock recovery,wipe,cross fingers and hope it boots
If u ever wanna go back to nougat just flash stock .tar and no issues from there
Huuuuuge credits to @lucastanciu
The guy stayd a few hrs in a constant bootloader fkup to made this happen and has made a huuuuge contribution so that this guide could be possible and as safe as it is

HOW-TO:
Flash something (a mod for example) AFTER you flashed the rom and modded bootloader
flash this stock bootloader in bl tab
at the same time flash in ap the twrp tar.
boot into twrp flash whatever y need to flash
flash back from odin the modified bootloader

"I dont have a g928f or g928c
Can you mod a bootloader for me?"
Well.........depends....... if im bored yea i like to help ppl
Just give me ur model number and i will try to make one for you. No promises tho

U forgot to mention that this 5.1.1 lollipop is faster than any rom. With this rom i got the fastest boot time ever! I recommend u to try this rom ))

Deal with the g928g

Gracias very good onli necesari recovery

You deserve a ten, but please fix it to get into recovery and do not put tatas red letters that scare jaajajjaja good eunsaludo from spain

So......first of all lets clear something out: nougat is fine. marshmallow is fine. even the first firmware that was ever released on the s6e+ was fine. But if for whatever reason you would want to downgrade to lolipop heres how:
WHAT YOU ARE ABOUT TO DIVE INTO INVOLVES HARDCORE BOOTLOADER MODS AND FLASHING SAMSUNG ENGINEERING FILES. PROCEED AT YOUR OWN RISK. NO ONE (INCLUDING ME) WILL BE RESPONSIBLE FOR THE ANY DAMAGE TO UR OWN PHONE.
So......downgrading to lolipop...... some ppl claimed it can be done by deleting some file in the .tar but that never worked for me.
If you have the sw rev check fail error upon downgrading....this is the guide for you
This will wipe all your data including internal storage (depending on how you do it)
Confirmed working on 2 g928f devices (one of em is mine) should* work on g928c but cant make any promises
disadvantages:
1. You cannot boot twrp while on the downgraded bootloader (still working on that tho)
2. You will only have systen-wide root. DO NOT flash systemless or it will not boot
3. Fingerprint is not working (still working on that)
4. You can only flash stock nougat or stock marshmallow from odin. You cannot flash lolipop tar,twrp tar,cf auto root tar or anything else
Instructions:
1. Wipe /data /system and /cache in twrp
2. Download this lolipop rom i cooked up in a few mins and flash it (dont mind the supersu flash in the rom. it doesnt work. flash this supersu
3. Download and flash this supersu (optional)(depends if u want root)
4. FLASH ALL OTHER MODS NOW BCUZ U CANT BOOT IN TWRP BACK LATER
you can try to boot but it wont. You need a bootloader
5. reboot in download mode and flash this modified bootloader
6. boot in stock recovery,wipe,cross fingers and hope it boots
If u ever wanna go back to nougat just flash stock .tar and no issues from there
Huuuuuge credits to @lucastanciu
The guy stayd a few hrs in a constant bootloader fkup to made this happen and has made a huuuuge contribution so that this guide could be possible and as safe as it is
