[Q] Downgrade from 5.0.2 to 4.4 via twrp ? - G 2014 Q&A, Help & Troubleshooting

I was just wondering if i can go back from stock ota updated 5.0.2 to 4.4 kitkat with my twrp backup without problems ?

You can downgrade to 4.4.4 without issues. But I never tested such thing using TWRP backup, but, as far as I know, KitKat bootloader is different of Lollipop, so you may brick some files in your Titan. If you really want to downgrade, do it properly, by downloading DSDALL firmware and then, using fastboot to order the commands. If you want to automate downgrade process, you can use my tool that you can take a look here. You still need to download the stock ROM apart, tough. xD

Ok thank you very much. Guess I'll have to use titanium backup and fastboot then. Will definitely check your tool

No problem. Glad I helped

No you can easily downgrade using twrp.. Just wipe system cache data and dalvik cache and restore the system, data and boot of your kk backup.. You should be good to go
Flashing the firmware will surely brick your device

You cant downgrade your bootloader, and yes you cant use custom 5.1 roms with kk bootloader But anyways, your bootloader is already upgraded, so it doesnt matter. And be careful about one thing, don't directly flash a STOCK kk rom on a lollipop 5.1 rom. Always downgrade to a stock based rom, and then do it.. CM11 based roms can be flashed directly (with wipes of course)

Thanks. Sorry because i was a bit unclear, the thing is i didn't update to lollipop yet and wanted to do it via ota. So I'm still on stock 4.4. But i saw your RaR rom and i think i will just flash that. I'm really sorry to ask again and waste your time but will i be able to flash other non-stock based lollipop roms then ? (just for fun of course because i think i will be using RaR as my daily )

I highly recommend you do the ota update before flashing any ROMs, because it will update your bootloader, and avoid issues After you get your BL updated, you can freely flash any ROM of your choice, just make sure you do a clean flash
And no you are not wasting my time

Flashed 4.4 TMobile over Rogers 4.2.2 xt1058...

Update: The ATT 4.4 firmware seems to have worked. Everything seems to function just as it should. Will someone release the rogers ota 4.4 update that I can flash in the future? If that's the case would I follow normal flashing behavior to return to my proper firmware?
shartwell said:
The first problem I had was that this 4.4 image had some bugs(Tmobile here: http://sbf.droid-developers.org/phone.php?device=0). The home button didn't bring me to the homescreen, the push notification area didnt work(clicking the little profile thing for wifi bluetooth etc,) and some other minor bugs.
What did I do? I tried flashing a backup of my clean 4.2.2 -- Doesn't work. Tried flashing another 4.4(dhacker i believe,) boot loop.
I'm tryign to use rsdlite to restore stock 4.2.2 image and worked through soem areas(editing the xml,) but now I get "failed to hab check for tz:0x4e" Google searches didn't return any relevant solutions for my situation.
I had got the OTA update to 4.4 while running TWRP and forgot(and was unable) to revert to stock recovery to accept the OTA update. This is how it all started. Does anyone have a solution to this error code? I just can't seem to find one(it fails during motoboot.img btw).
Ps: I heard it could be my BL being upgraded to 4.4, which peope claim can be downgraded, but I've yet to see how.

The only 4.2.2 sbf firmware file that will flash correctly is the post camera sbf firmware, so make sure you are using the correct firmware, have you attempted to reflash the T-Mobile sbf firmware again? Sounds like a full wipe was not done after you flashed the T-Mobile firmware.

Thanks for the quick reply. I have to love you guys here at XDA
I've managed to get the ATT firmware to work perfectly. Will the 4.4 firmware be added to sbf in a little while(seems the ota is slow. I randomly got it.) for me to reflash like I did ATT?

You can flash the rogers 4.4.2 sbf firmware when its available, the only thing, which needs to be confirmed is you may not be able to downgrade. Do not flash the other 4.4.2 firmware other than rogers just to be safe , people are flashing crap and messing with modems,panicking that their data is screwed and flashing back and bam dead phone. The resurrection thread works for some but not for everyone. Wish people would flash kangakat, eclipse, cm11 or gummy rom , its safer and you have stock based ROMs with all motos goodies and custom

Where can I find installation for CM(my favorite mod) for my device? I haven't seemed to find any. Might be that none has been developed.
Otherwise can you suggest another similar mod that would work for my device.
My data seems to be non-functional for ATT firmware, which is fine for the moment, I'll leave everything as is(unless I install a mod) and flash the 4.4.2 rogers when it becomes avaliable(Do you think it would be within the next couple of days since the OTA is out?)
Ps: The other option I have is downgrading to 4.2.2 than using the OTA update(which is what I should have done in the first place...I forgot how to flash stock recovery for OTA,) but it seems the bootloader has now been upgraded. I don't suppose there is a way around that to restore 4.2.2 stock?

Makes sense. Figured that was it. How can I get a custom recovery onto my phone, though, as it's unrooted on 4.4(which I've heard has no current root.)
Thank you for all the help, hope I can get cm working soon and forget about OTA in the future.

(Q) what's the easiest way to update Bootloader and Radios?

So I'm currently running BlissPop 5.0.2 and I wanna upgrade to a 5.1 ROM, but I was told I need to update bootloader and Radios, sorry I don't have much experience on this Subject, So what would be the easiest way to update both of these?? Thanx
And say the ROM I'm flashing doesn't work out for me for whatever reason and I need to Restore my nandroid backup (5.0.2 ROM) would I have to downgrade or whatever the bootloader and Radios again?? I'm confused lol thank you

easiest way to update is with fastboot and google images here is link to images https://developers.google.com/android/nexus/images
if you want to keep data or it wont flash follow this http://www.androidpolice.com/2014/11/12/running-into-the-dreaded-missing-system-img-error-flashing-android-5-0-factory-images-heres-how-to-get-around-it/ but you need to erase data because your on a custom rom and it probably wont be compatible with stock rom once you have updated everything reflash a custom recovery or dont flash the stock one at all then flash a 5.1 rom and good to go
What about all the Bootloader and radio zips that can be flashed through TWRP? I've read about people flashing the updates while still being on their 5.0.2 ROMs and everything still works fine, I don't have access to a computer I would like to just update straight from my phone without a Computer if possible? Think I could flash the Bootloader and radio updates through TWRP then reboot n after everything is all good go back and flash the new 5.1 ROM and gapps?

i don't know if anyone has twrp flashables for the updating bootloader and radios your searching is as good as mine here i am not experienced with that i always used factory images or ota updates to update those things.
but if you happen to have a backup of your stock rom in twrp you maybe able to just go back to stock then flash back your stock recovery then update with an ota but for an ota to work it has to be all stock no root no nothing just stock.

This is kind of a deal breaker for me, that and the broken rar archive. BUT when it starts working I would like to use your ROM because I love stock roms with minor modifications and debloat. Did you use this xposed framework? http://forum.xda-developers.com/showthread.php?t=3034811
When I flashed the completely stock version, it broke, no data/wifi/bluetooth, and everything crashed. I think it was because I wiped first and since this is an OTA I shouldn't have done that, but now I am worried about trying again, since I just got my phone back up and running. I must say thanks for that, because flashing using TWRP and your ROM gave me TWRP back, so I was able to downgrade back to 410c stock from your ROM. I'll wait for the radio problem to be fixed before I try again.

You can flash safely with TWRP. Go ahead and upgrade to Stock Lollipop via KDZ then you can try flashing one of brossovitch's ROM. It worked for me. Just follow this http://forum.xda-developers.com/showthread.php?t=3088131 guide if you get broken IMEI or/and Baseband. It will help you get it back as well as get Lollipop on you phone.
Good luck!
So if I read that right, you have to flash the Stock 5.0.2 using TWRP, then flash the Stock 4.4.2 using the LG Flash Tool, then flash the Stock 5.0.2 using the LG Flash Tool, then root then unlock bootloader (is that necessary with the D415? I never did that before) and then use Rashr to flash TWRP and then flash brossovitch's LollipOptimus ROM, just to get the IMEI/Baseband to work? Seems like a lot of hurdles. Why not just flash the 5.0.2 KDZ and then root and flash TWRP possibly with or without bootloader unlocking and then flash the LollipOptimus ROM, or even just flashing it like an OTA from TWRP? Will the LG Official OTA break the IMEI/Baseband?
And has anyone tried the linked Xposed framework?
Thanks for your help!

No, that is if you had a failed flashed and did not have Stock Download mode which you lose if you unlock the boot loader (which is technically unlocked). Unlocking bootloader is optional, I should put that.
If you have unlocked boot loader then you need to either flash the lag.img or bross's stock ROM with laf.img in it.

I'm going to try xposed again.
I'm also going to upload the partitions needed to make the bseband work.. There's a way to be easily flash them to go to either.
Stock lollipop is just different. And the custom roms are based on KK. so we gotta be able to go back if we want..
We can.
With L90 utilities you can flash your laf partition or toggle it between fastboot mode & s/w Upgrade (firmware download) mode.
From there you can use adb to flash the proper partitions.
IE:"fastboot flash radio modem.bin"
Which would likely work..

Am new to TWRP so excuse me for asking, but since I restored back to 4.4.2 my phone is better than it was before. I would like to upgrade, but I'd like to be able to revert back to 4.4.2 if I have a bad experience. I backed up my phone with TWRP, can I flash the kdz with the LG tool, and then root and get back to TWRP and flash the ROM to make the radio work, and then back up the 5.0.2 ROM and switch between the two?

Since I cannot reply directly to the main thread or the How to fix IMEI/Baseband Unknown Issue (D415) thread, I will ask here.
I am currently running the KitKat stock and rooted, with the original laf.img and TWRP recovery, de-odexed system, and several unwanted stock apps uninstalled.
From my arrangement, to upgrade, I can go to download mode using Vol + and Plug USB (because I haven't zero'd out my laf, right?), and use the 2014 LG tool to flash the Lollipop KDZ. This will cause the data/wifi/bluetooth signals to stop working, as well as losing root and TRWP (correct me if wrong). From there I would need to root and flash back TWRP and then from TWRP flash the LP-[5.0.2]_L90_D415[boot-system-laf-aboot-modem.zip] to get the signals back.
At this point, would I then be at stock rooted lollipop with TWRP and download mode and have a useable phone? If I do a CES flash as recommended, would I lose all of my currently installed apps and data? If so, I should disable xposed first, right?

You WILL lose all data but you need to use CES to fix, I believe, the partitions. You DO NOT have to flash the LP-[5.02]_L90_D415[boot-system-laf-aboot-modem.zip] if you go to KK then to L using Lg Flash tool. After succesful Lolli flash, then root, install twrp, and flash one of Bross's rom.
But if I want to go to stock 5.0, with twrp and download mode intact, what do I do? Flash using LG Flash Tool, root and flash twrp and I'm done? This won't cause radio problems?

I promise, if you follow my guide, everything will be fixed. You only lose radio if you flash something wrong. For example, flashing one of bross's ROMs while on kk. That is a bad idea. After you flash to lolli with lg flash tool, you can root and flash twrp. You WILL NOT lose Download Mode unless you zero out the laf by following the Unlocking Boot loader guide.

Help! How to downgrade from marshmallow ( nexus experience rom) to lollipop (stock ro

Can anyone pls tel how do i downgrade from marshmallow 6.0.1 to lollipop 5.0.2?
Currently my bootloader version is 48.83. I dnt remember what it was on lollipop. Pls help!
Just use your backup that you made prior to upgrading to Marshmallow. If you don't have the backup, just flash a different ROM. Plenty of guides on the site.

I have made the backup. But i have heard about many people hard bricking the phone when trying to downgrade and then again upgrading via ota. Thats why i askd.
If u are on custom rom other than motorola marshmallow soak test ota.. you will not get ur phone bricked when downgrading. Hard brick occurs if u downgrad from soak test ota to lollipop. In your case u just need to flash retaildsdsall firmware via fastboot mood. Search for tutorials for reverting to stoc 5.0.2.
Just DON'T CHANGE BOOTLOADER. You shouldn't be able to downgrade bootloaders but Motorola screwed that and with M bootloader you "can" downgrade, but bootloader downgrade results in BRICK. Just flash the rom you want, EXCEPT THE BOOTLOADER. For custom roms you shouldn't have problems.

All I can say is that I was on Nexus Experience 10.0.4 (Marshmallow) but could not get adopted storage to work so restored my previous AOSP lollipop ROM from TWRP backup and no issues. My Bootloader is 48.82. I have never used the soak test version or OTA version of marshmallow.
I have also in the past restored stock lollipop V5.0.2 from other lollipop versions with no issues.

Just don't downgrade your Bootloader and you should be fine, if you're using an easyinstaller script to flash stock Lollipop make sure and remove the lines of code that flash motoboot.img & I'd also recommend removing the line that flashes gpt.bin to be safe.

Latest Bootloader - Can I Install Lollipop or KitKat Roms?

Hello
I have a moto g titan xt1068 dual sim which was originally running stock lollipop 5.02 and was updated with the OTA stagefright update and then the OTA MM6.0 official by motorola.
I have since installed custom roms cyanogen 13.0 and cyanpop 6.2
I know my bootloader is now the latest, so my question is can I now only install MM based roms? or can I still install KK & LP based custom roms?
or will installing LP or KK based roms hard brick my device?
Many thanks for any help
i'd like to know it too...
I'm not sure, but I can't really see why not. The bootloader being the latest changes jack squat on the question of being able to install older versions of Android or not. I mean, I WAS able to install the stock LP ROM on the MM bootloader, but your mileage may vary.
Yeah you can. Just don't try to downgrade your bootloader while downgrading to previous stock Android version. Itll brick your phone.
But just flashing custom Roms is safe.

That's bullsh-t.. You can always downgrade your rom, but you have to be sure you're not downgrading your bootloader. So if you're using oneclick installer you have to remove the command from the script which will try to downgrade your bootloader. Also after downgrading you have to be super sure that you will not update it with OTA!
Btw.: I'm not sure downgrading through fastboot can even brick your phone.

That's right.. You can touch your bootloader only when you have to upgrade it, for example in case of updating to Android N. Which I think will never happen (of course officially).
Here you can find a nice guide to downgrade your Android version.

FFS, Did you actually read my post. I said NOT to Downgrade the bootloader while downgrading to a previous stock version via fastboot.
