[Q] Downgrade T999L back to 4.1.2? - T-Mobile, Samsung Galaxy SIII

Is it possible or will I face a brick? I wanna try the MIUI v5 Rom but I can't flash since I don't have the old LTE bootloader

From personal experience..
Only flashing an older boot-loader if coming from the more recent one, that will brick your device..
Dont quote me on that.. But im pretty sure thats the case

Sounds about right..
There a a few roms that I'd like to try for my T999L, but I wont mess with my bootloader..
I dont want anything to do with Knox. Even though you can install a 4.3 rom with out it..
The Bootloader still contains remnants of Knox..
Miui v5, looks like a 4.2 rom.
I dont see a problem.. Make a Nandroid first.. Then do a factory wipe, and give it a try..
if it doesnt work.. you can always go back..

I've tried to flash it and i keep getting assert failed error. I looked at the built prop in the log on TWRP and it list all the bootloaders but MK4. So i'm assuming its because of the bootloader it won't let me flash. Even though it says d2tmolte is supported

Sounds like the Rom your flashing isnt meant for your Carrier/Device..
Just to be sure.. Id check to see if you have the most recent version of TWRP installed..

It's the latest one from Goo Manager. twrp 2.6.3.1. And blackwing made it work for the t-mo s3 and lte version but it still won't flash. Is it just my phone?

I doubt its the phone...
Im a semi novice on this phone.. I fare better with Nexus devices..
Im sure your just missing a step.. If your phone is working put it off, and wait until someone with more experience might be able to help..
If your getting an Error 7, that is likely due to the Update Script which TWRP looks at before any kind of flash, its mainly to protect people from flashing the wrong things on their devices.. Its saved my ass a couple of times..
Find the original thread for that Rom..
and post your question there..

No. Just flash miui with a custom recovery and you should be good. In the future please do not ask similar questions in different threads

Error Status 7

So, I can't post in development yet, so hopefully enough folks here can help me out.
I've done everything I can to get my phone back to stock to bump up to LG8.
I'm unrooted and I flashed the bare bones stock LEN ROM back onto my phone so now both my baseband and build version match (LEN). No root, stock recovery and I'm still getting that same Status 7 error.
Anyone have any other suggestions?

If you flashed a bare bones ROM ull be missin stuff and it will fail. Flash stock tar in Odin and all will be well. Stock tar: http://samsung-updates.com/get/1917/Samsung_Firmware_SPH-L710_SPR_L710VPALEN_Android_4_0_4.html
Really tho, the only important thing from the updates was the modem. Could always DL that here and flash seperately. Then manually chg or build so you don't get the update prompt. Seems like a lot of work on your end just for a worthless ota. At any rate tho that link should solve or problem

Ah, let me clarify.
I tried through this thread: http://forum.xda-developers.com/showthread.php?t=1810341
So that is the ROM I used, that's what I meant by bare bones stock. No root, no patches, just the basic ROM
thanks though
Wow sprints network sucks. anyway this should work, did for me. would have a nandroid backup handy just in case https://www.dropbox.com/s/0ip3ck2gzdfk51b/lg8.zip Thats the update w/ no checks that will give you status 7. flash in cwm

if your on stock then i cant see there being any problems, i think ur failing the checks because of somethin small ur missing. At worst you wont boot/softbrick thats why the nandroid is reccommended so you can always reverse if it happens. was getting tired of status 7s myself which is why i did that when i was runnin stock. workd for me. But ya, worst case scenario, u gta restore ur nandroid, should be fine tho. You can flash it rooted btw. it will flash with root just fine although itll probly patch it. Needs cwm as well, will most likely fail in stock recovery as it is not signed anymore

gotcha, thanks,
I do wish that these errors were easier to decipher, would make life much easier...
softbrick oh well, rollback time

Wonder wat stopped it from workin..
no clue, got stuck at the 'Samung' screen on boot.
ended up reflashing the stock LEN ROM via Odin.
know where I can just get a stock LG8 ROM?
how have I missed this thread the past 3 days.....

however, this is downloading at 35kbps....

Cannot flash recovery.

Well, since few days i had issue that sometimes i couldnt enter recovery. Now im on stock and i cant flash it. In the moment when stock recovery should change with CWM i just get blackscreen :/
Which one do you use? Try this from attachment.
Thats kinda hard to flash it cuz i cannot enter even stock recovery. Should i take Ace for warranty?
Well, you could empty your SD except for that one file and count clicks...
But if you can downgrade to 2.x, try to do that and then back to 4.x first, that's a mostly 100% reflash of your phone... In fact kernel and bootloaders (SBL/"Normal", mem_init, power_management) are all that's required for recovery AFAIK, but the very issue of LCD problems in recovery means there's probably more...
@up
Gonna try it. For gb i need 3parted update right?
Worked 2-3 times, installed cwm and again same problem
Now im trying all time to go into recovery, tried over 10 times, none of this tries were succesfully

It looks like you flashed a ROM for the t805 not the t705.
First let's get you back to stock.
Download the firmware for your device from the link below.
Follow the instructions to install it. This will get you up and running again.

No need to flash the bootloader after flashing the stock firmware.
I would do a factory reset in recovery.

Hi ya, I have already done that but issue still there. Now I can boot up and start the setup process and the tablet freezes and reboots about 1 minute into setup process near where you have to sign in to google
Any more suggestions:crying::crying::crying: please
Tbh I think you have a hardware issue.
Now new problem when I try to install twrp it will not do it, If I go into the system recovery and try to do factory reset an error shows as follows
E: unknown volume for path {/sbfs}
E: unknown volume "/sbfs"[/U][/U]
Data wipe complete.
I thought it may be battery related but I have changed to a genuine new battery. still same issue
Please please Tech God help me

No, flashing a kernal won't result in a different twrp. BUT inside the kernal downloads he also has a few Twrp releases. You will need this one https://forum.xda-developers.com/devdb/project/dl/?id=22806

Well then it's not a Twrp issue.. Ask the rom maintainer.

Question twrp when

im not saying im gonna root my a22 yet but is anyone gonna port twrp or nah
when you try to write twrp, you may need to unlock bootloader first. and i have the problem with param file, because it's compressed by lz4 with another methods. can't open it with 7zip anymore.
do you have it?
same. i thought i'd be able to flash a custom ROM but I'm stuck with my device not listed on TWRP

Well firstly it's done on a old version of odin with the old layout of firmware files, which won't work. And if it did work there's a high chance there's no custom roms for A22.
