So I had DarkLord N5 on my N9005 before, which was awesome, but it had performance issues (especially when gaming). Then i downgraded to Stock KitKat using Odin and after boot up It showed No Signal, and everything was freezing and force closing. I somehow went to settings and found that i also have issues with IMEI and Baseband version, it was all unknown. The worst part is i did not backup my EFS. Any help guys please :crying:
I also have no audio playback
Im no pro here, but as i found in my research it is hard to downgrade from lolipop to kitkat as in 5.0 new architecture has been presented which they called art. I think. So it gives lots of incompatibilities. I tried the same as you but i ended up going stock lolipop for a while.
Yesterday i flashed Ressurrection remix 6.0.1 Marshmallow based off Slim roms and CM and i admit this is so far best rom i have tested. (Unless you need all fancy spen features)
I'd try to stick to anything that is 5.1 or above since great battery life.
Sorry for not much info, but i couldn't get past your post unanswered.

I had many experiences with downgrading from new version to old version with my S3 and my Note, but never had this issue. Something is causing this...
founded a old backup of CM11.. Flashed CWM and restored to CM. Works flawlessly, but still no sound and those stuff

So i had problems with my either s2 or note 4.
But afaik if u have updated your bootloader there may be no way to get back. And lack of IMEI on reverted KitKat isn't anything new. I bet going simply to anything art. Based will do.
People here are arguing on same issues as yours. Just don't listen to these "flash with odin" guys.. This doesn't work. Even if u flash the stock one.

I would not try any other ROMs before trying to flash the latest stock rom from sammobile.com. Hopefully, this will resolve the baseband and imei issue. Sometimes, the missing or wrong imei is caused by a mismatch between the bootloader and modem firmware.

I did downgrading from 5.0 (CM12) to Stock 4.4 KitKat in my S3, but never had issues like this.
Downgrading from a cm rom to a stock rom via Odin can be fine because installing a cm rom does NOT alter the phone's bootloader or modem. Trying to downgrade from stock 4.4.2 to stock 4.3 with Odin on an s3 cannot be done.

Oh, never knew about this, thanks for the info
Sorry, I meant to say that installing a cm rom DOES NOT change the bootloader or modem. When you flash back to stock via Odin, you are simply writing over the existing modem and bootloader with the same bootloader and modem if you are flashing the same stock rom that was on the phone before installing cm.
I flashed between KitKat and LP official just fine.

I recently flashed the temasek and official CM11 roms, but the baseband has been unknown since.
So I had flash back to the original rom that I was using, my QUESTION is that I like cm11 alot, so how can i fix this problem?
Which Note model? -- N9005 or N9005 variant? -
T/w8 ?
Which recovery do you use?

It is actually N9006 but temasek's v45 for n9005 and earlier worked fine, I am using CWM rec.
Until recently, temasek's v46 and 47, the baseband becomes unknown
Last time a user had that issue, he fixed it by flashing stock via odin and then CM but he was using a n9005 so I am not sure if that will work for you as well...However no harm in trying.

I'm sorry but I speak poor English. What is a Stock? I've tried flashing kernel and baseband but it did not work.
When I use Temasek's v45, it shows that my baseband is ML1, but when I use further version, it becomes unknown.

I just flashed a n9006 rom made by chinese romers to get my note mp4 into a note3, or i could just use temasek's v45.
I just wanna use the latest cm11 rom but it seems that it's not quite possible for now, so i'll just stick to my original rom...

It also worked for me although sadly I could not use my backup again after flashing back to cyanogenemod so its time to start downloading. At least my phone is fully functional now, even if I lost a bit of data.
I had the same issue move than once, i would lose imei number etc.
Found out that it wasn't prompting for pin unlock on boot.
Since removing this I've had no problems
Yea it also wasn't prompting for ping with mine.
Though starting again fresh does work, I am currently again on the latest nightlies. however if this happens again I will probably wait for a stable release because having to reinstall everything is not really desirable.

I seem to be having an issue with downgrading my S5 G900H Exynos to Kitkat from Lollipop BOAD. I've tried 4 different stock Kitkat firmwares from sammobile but all of them cause the phone to hang at the Samsung logo however I can flash back to stock lollipop BOAD and it works fine again.
ODIN gives me no errors when I try to flash kitkat or lollipop and infact both gives the "PASS!" mark what should I do?
I downgraded to KK from LP the other day, and ended up stuck at the Samsung logo too
Tried factory resetting, didn't work
The only thing that finally worked was flashing the same KK ROM again over the top of the one that got stuck at the Logo
Once I'd done that, it booted

You might need to flash the PIT file for your model S5, maybe the partitions are different between ROMs for that specific model
Be sure to get the exact PIT file though or you'll brick it
PIT file and KK ROM in ODIN at the same time, it will flash the PIT, then it will flash the ROM

You could flash a custom recovery like TWRP, but unless someone has made a flashable zip of the stock firmware for custom recovery it'll not work
You could flash a custom KitKat ROM from TWRP
The only method that works for mine is flashing CF Auto Root, to gain root, then using TWRP manager from Google Play to install TWRP Recovery
This will void your warranty though

Mine is similar to that too. I have to install CF Auto Root first and then install Flashify and then install TWRP via flashify img file to gain custom recovery

Stupid question, but you did factory reset after upgrading to LP?
KK leaves behind rubbish files which cause battery drain, I got the same after first upgrade, but after a reset, it has been great since
Performance is definitely better with LP this end too, but you're not alone, the majority who upgraded say KK is way better atm

Hey, I've updated to Lollipop and I have upgraded bootloader, modem, etc with stock ODIN rom (lollipop). I prefer KitKat... do you know how I can go back to running KitKat? I tried flashing KitKat but ODIN fails after the lined hidden.img.ext (something like that).
Thanks! :victory:
that is weird, i have downgraded to NF4 and it was working. problem is that the baseband is not downgraded, so i didn't have a signal.

Thanks, I had flashed kitkat, but then went back to Lollipop cause I missed the Note 3 lollipop custom rom i was using hahaa!
I have a GT-i9505 that I've been running the stock Jellybean Touchwiz 4.2.2 ROM on since forever (I9505XXUAMDD). I recently discovered compatibility issues with some updated apps and decided to give the latest Touchwiz a spin. Since my phone is rooted i couldn't get the update via OTA so I downloaded the latest Touchwiz ROM (I9505XXUHOL2) and flashed it manually. It went well but I didn't really like it and I didn't have the time to set everything up again so I restored my original setup using a nandroid backup but now things are all wonky. I can't mount my SD card and wifi won't turn on. I suspect this is because the kernel is still the one from the 5.0.1 flash while the ROM is back to the 4.2.2 one. Under the about device menu the android version shows 4.2.2 and the build number is the original I9505XXUAMDD but the baseband version shows I9505XXUHOL2 and the kernel version shows 3.4.0-431985. In addition when booting up the phone it shows the "SEAndroid...kernel" message in the top left corner; not sure what this is.
Is there a way to remedy this or am I SOL and forced to use a later version of Android? Thanks in advance!
Edit: So further research suggests it's actually the Baseband version that is causing the problem so flashing the correct modem should fix it. Could someone please show me which modem is correct for I9505XXUAMDD? Also, will this fix the kernel message I keep getting? Thanks!
You can't downgrade from lollipop that easily
There's threads in general relating to downgrading
Could be a mismatch between the phone bootloader and baseband. What bootloader version and baseband is on the phone? If they match, it could just be that the bootloader and modem are too new for the rom.

Yeah, I realize that now. I put too much faith in the nandroid restore. I had tried out the JFLTE-GPE ROM once before and a nandroid restore reverted the device without issue so I just assumed it would do the same in this situation. I will look into the downgrade process.

I was under the impression that a nandroid restore would flash the bootloader as well but my faith in nandroid backups isn't what it used to be
Guess I'll have to look for the appropriate bootloader and modem for the ROM.
You can install the Samsung Phone Info app from the Play store to confirm your bootloader and modem.

Wifi is out so I don't have access to the play store
I used the terminal emulator to check the bootloader version and it's indeed still on I9505XXUHOL2. I've read somewhere that once a newer version of the knox bootloader has been installed, attempting to flash back to the 4.2.2 bootloader will brick the phone. Is this true?
Thanks again!
I don't know about the 9505 but you can't downgrade on the s3, i337, and note 2.
Personally, I would flash back to stock to make sure everything still works.

Will do. I'll pull up the I9505XXUAMDD from sammobile and give that flash when I get home this evening. Thanks again!
So I flashed to stock I9505XXUAMDD but the wifi and sd card issue remains and the bootloader still shows up as I9505XXUHOL2. Not sure how to proceed.
I'm starting to get the feeling that 4.2.2 is a lost cause...I guess downgrade on GT-i9505 is not possible.
Edit: Baseband version is now I9505XXUAMDD and wifi is still not working.
Update: Flashed to I9505XXUHOF2 and everything seems to be all peachy keen for now. Will update again once I restore all my apps and data.

No it's not. It's not possible because you cannot downgrade the bootloader.
Perhaps you can still go back with 4.2.2. custom rom but in my opinion it's really not worth it. It's not worth to stay on an outdated version with all the security vulnerabilities. I would recommend anyone to use CM because then you can run the latest software on your phone.

Thanks for confirming and thanks for your input :good:
I really did enjoy the Jellybean experience on the S4; going to Jellybean from ICS felt like an upgrade. I feel like that was the best match for the phone and it just went downhill from there (as far as the S4 is concerned). I suppose it's time to move on.
Update: All apps and data fully restored and it seems stable save for some small quirks. Not liking Lollipop though.
Hey guys, everything I've read has said once you update beyond 4.3 you can never go back down because of knox. I also saw someone mention you actually can downgrade to a custom ROM based on a previous build just not to stock. Can anyone clarify this for me? I'm not worried about breaking my warranty since it's long since expired. I'm on the rooted 5.01 Goldeneye ROM and want to go back to a 4.2 ROM. strictly for tethering purposes
What is the model # for the s4?
It's the AT&T sgh-i337

I can't recommend any 4.2 roms as I don't have the phone. Also, I don't think such an old rom will work on an lp modem and bootloader.
