Hi I've recently unlocked my N7105 using the method where you downgrade to 4.1.1 and unlock through the hidden menu. Since doing this my phone has had intermittent signal or no signal at all. I have since flashed different rooms, official and cyanogenmod. However the problem still remains. I then upgraded to official 4.3 (with knox ) and the problem still exists! Any help would be greatly appreciated.
Thanks I'm advance guys.
If you are talking about your phone signal then you most probably have lost your IMEI by downgrading the FW , do a search around this forum you will find many threads along that subject, I think you can regain it by flashing different kernels or ROMS.

What do you mean the recovery OS? Also the bootloader cannot be downgraded as I have an N7105 on android 4.3 with knox

It'll be the OS that originally came with your phone at the start.
Yes, you're right. You cant downgrade the bootloader - oops! my bad!

Have you updated your baseband and modem to match your new ROM? You need to flash them in desktop Odin, normally a few times in a row, and once you reboot your WiFi etc should be back.

Ahh, well if you still have the 4.2.2 bootloader then you'll probably have some WiFi/sound issues depending on the ROM you pick. You can always flash a 4.2.2 Based ROM to unbork your phone and then look for an alternative?

Ok, you must be wondering why the heck anyone would want to downgrade from 4.4.2. Well I had one noob moment and a couple of unfortunate coincidences. I haphazardly flashed a rom for an I9505g onto my phone. Luckly I can still boot up and connect to my wifi. If I turn the airplane mode off then the phone goes haywire. Im sure that isnt fixable.
My difficulty is finding a stock 4.2.2 ROM to flash.
I would just flash the recovery i have, but, it somehow is corrupt and sends my phone into a bootloop so i have to reflash the 4.4.2 again to get anything to work. Really, i think all i need is a link to get me going in the right direction for the files i need. If anyone could hook me up i'd really appreciate it.

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.
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.

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.

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
With a locked bootloader, the phone is limited to customs roms based off a stock Samsung rom. Aosp and cm will not install or run.

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.

You can try but I don't think you will have a functioning phone in that the imei will not be properly displayed which means the phone wouldn't be able to connect to the carrier.
