[Q] Remove Cyanogenmod Problem

Hi,
I had stock 4.3 firmware on my att i747 galaxy s3, then I decided to flash cyanogenmod. everything went well but i dont really like it.
Now I want to go back to stock. I tried flashing the stock rom with odin but it fails and it says this on the phone:
ODIN MODE
PRODUCT NAME: SGH-I747
CUSTOM BINARY DOWNLOAD: Yes (2 counts)
CURRENT BINARY: Custom
SYSTEM STATUS: Official
QUALCOMM SECUREBOOT: ENABLE
Warranty Bit: 1
BOOTLOADER RP SWREV: 2
SW REV CHECK FAIL : Fused 2 > Binary 0
The android version it shows is 4.3.1 and im able to use it normally with the cyanogenmod.
What can I do to flash a stock rom back?
EDIT: used triangle away and the custom binary download says "no" now and the current binary says "samsung official" but still get the same problem.
Thank You

You need to flash a stock ROM that has no boot loader attached to it. I just reverted my S3 back to stock from CM11 so that I could sell it. Flash a Rom.zip through recovery and it should work fine. I see you are ATT so I suggest this one: http://forum.xda-developers.com/showthread.php?t=2540998. You have the choice of Stock Rooted without bootloader which is what you will be looking for. This thread also has everything you may need. Do not attempt to use Odin to flash roms with older bootloaders or you will find major issues.
You will almost definitely need to wipe everything so back everything up and be sure to take a Nandroid.

In that thread you have 2 good options that I can see. Scroll down and you will find one ROM by upndwn4par/full and another debloated directly under it. Which you chose depends on if you want Samsung/ Google software on it. The upndwn4par file will have you closer to stock than the other. Please be sure to read a couple pages, even if you don't get any immediate knowledge from it you will become way more familiar with these processes. It's worth the time, and safer for your phone.

Thanks once again, i will download the debloated one. But I have a question, that won't be a stock rom right? If the bootloader is the problem is there a stock d2att 4.3 rom i can flash?

That is a stock ROM. It is just pre rooted with knox removed. It is a modified version of the Stock OTA with the problematic parts removed..

You need a custom recovery to flash this. CWM or TWRP. I'm not too sure how you got to CM without one but be sure you have one and then flash the Rom from above. You can install CWM with the app 'Rom Manager'.

I installed CWM but now that i used cyanogen for a while im starting to like it. The only thing that I dont like is the music player. I downloaded google play but it is even worst, my playlists are not even in order. Is there any way of flashing the stock samsung music player on cyanogenmod or is it integrated with the touchwiz?
Thanks for all the help you gave me so far.
EDIT: I found this thread about ported s4 apps: http://forum.xda-developers.com/showthread.php?t=2267029, can i just flash it with CWM using cyanogenmod?

You can not flash that S4 port. It says it is specifically for the Galaxy advance. Also you are correct that the Samsung player requires Touchwiz. Try Power Amp, it has pretty good reviews and features. A 3rd party player is probably your best bet. You can cherry pick for features

I tried a lot of players and didn't like any. Flashed the ROM you indicated using CWM and it worked. Did it all for the player Everything is working fine now and I really like how it doesn't have all the bloatware from att.
Thank you very much for the help.

Upgrade firmware only to cof8?

Hello all,
I was wondering if I can upgrade the radio and bootloader to COF8 without running a 5.1.1 ROM. I am rooted with Ktoonz kernel with firmware AOC9 with 5.0.2 stock ROM.
TIA.
Bob

Once you upgrade bootloader , you can only run 5.1.1. Not sure about ONLY upgrading radio.

Thank You for the reply..
So once I ODIN the new firmware, I need to load a 5.1.1 rom before letting the phone boot up to the 5.0.2 rom?

You cannot boot a 5.0.2 ROM once you are on 5.1.1 firmware. That's the way it is as far as I know. There is no downgrade possible once you are on 5.1.1
Personally, I have no issues with 5.1.1. Great ROMs now. Great battery life. I personally do NOT care about Knox or the ability to run Samsung Pay. Just my 2c.

Thank You.
SO.. Once I start the firmware upgrade.. I must immediately load a 5.1.1 rom.
1. Upgrade the baseband... dont re-boot.
2. Upgrade the Bootloader... dont re-boot.
3. Install a 5.1.1 rom... reboot. Thinking of the ROM below.

I won't tell you what ROM to choose. Yes, coincidentally I am using the Xtrestolite rom with the alliance frameworks, but I have a lot of other favorites both on TMobile as well as the International galaxy S6 or S6 Edge roms. The key is the kernel which gives you root. The International ROMs as well as the Tmobile ROMs all work with the latest Unikernel version 6. Once in a while if you run into the no call audio issues, simply flash the latest no call audio fixes. I don't have links right now but most of the OPs on these ROMs will list the no call audio patch files basically to have Tmobile as well as Canadian variants work universally. So yes, simply use Odin to install the latest OF8 bootloader and modem, which I am on. Then flash any 5.1.1 ROM of choice followed by the version 6 Unikernel and boot up. Boots can take up to 10 minutes so do't be concerned you may be bootlooping.

One more question before i begin
If i cant boot a 5.0.2 rom after the fiware upgrade row do icheck to see if the upgrade worked and flash a 5.1.1 rom

Odin should say pass if a successful flash. Plus use the three button method....Power, home, volume up to boot to recovery and see TWRP. Best way to do the TWRP verification is to use three button, Pwr, home, volume down and hold to get to the first bootloader screen, then when you cancel out using volume down immediately hold the powr, home, volume up to get to the twrp screen. Make sure you have a 5.1.1 ROM of choice on your Phone along with the unikernal and before you upgrade, so that you have something to flash
If you are unsure about any of this, there are a slew of FAQ's on this stuff. So make sure you fully understand what you are doing and having the files in place PRIOR to doing anything. Like all the OPs state here, I'm not responsible for anyone bricking their phone or doing anything that makes their situation a now aht do I do to fix xyz issues. As long as you have the latest Odin mentioned in various OPs here, are comfortable with the process of using ODIN, testing their setup to make sure that your phone and cable and opertaing system have proper drivers to see your phone when in download mode etc, this should not be a big deal. That said, I don't know the level of your expertise in doing this so all I can do is warn you to check and double check you have everything in place before proceeding.

Post #8 details install guide for Tmobile users. This whole thread is a great guide for installing firmware and a 5.1.1 ROM. I'm not making a ROM recommendation since that's a personal issue, but this is a good starting choice so you should look at this thread and possible use this as a good guide for how to do stuff, including having this ROM on board you phone as a starting point. Just offering you everything I can think of before you jump in.

Thank You So much. Im gunna go for it.

No ROMs for SM-T807R4, correct?

This is the US Cellular version which I bought used by mistake on Ebay (the description said wifi and the seller had a no return policy.) It's been fine for my wife who mainly watches movies on long flights but since the MM update, browsing (or anything using the touchscreen) has been difficult due to the screen freezing every couple minutes. Closing and opening the case unfreezes it, as does hitting the power button twice.
I have recently rooted it and disabled a bunch of apps but that has not cured the problem. I don't even know if it's hardware or software but I'd like to try another ROM on the chance that it fixes the problem. As far as I can tell, there are no ROMs for this (snapdragon) variation which I guess isn't a surprise since it wasn't a big seller. Just looking for confirmation that there are no aftermarket ROMs or a link if there are. Thanks.

Phoenix Rom and Iron Rom was the Roms I had used on it. For the freezing I'll suggest u download the full firmware from samobile and with twrp recovery wipe system, data, internal memory and cache like three times before you flash the firmware to it through Odin

You used the Iron ROM on the US Cellular version? The T807R4?
I'm going to flash TWRP, wipe a couple times, then flash the official Samsung MM firmware. It's 1.7GB. Any idea how long that will take? When I rooted it was a pretty small file, 30MB, and it seemed to take longer than I would have thought.
Thanks for your help.

I thought ROMs were processor specific, i.e., a ROM built for an Exynos processor would not work on a Snapdragon. Is that incorrect?

Roms for T805 does work on T807, only the call out don't work but can receive a call [emoji338] in. All u need to do is after flashing twrp use it to backup boot, Moden, EFS, and radio but only boot backup will do though. And then restore the backup on any T805 rom u install to get mobile network. And when I say T805 rom I don't mean the stock firmware in Odin flash

I don't care about the phone functions, the tablet is only used for email, web browsing and watching movies.
When I start TWRP, the backup options are boot, cache, data, system and something else. Nothing about modem, EFS or radio. So if I backup boot, then wipe and flash another ROM, do I need to restore the boot backup or does the ROM contain the bootloader also?
Thanks for your help. I have flashed ROMs on Motorola phones but never on a Samsung device.

No Radio on ROM Flash

no matter what i do with my htc 10, i always lose radio on flashing rom, i looked and it say only flash oreo roms if you are on oreo firmware, which is what i am doing. i am formatting data like it says to do to rid the encrypyion. because of this i have to restore from RUU everytime to fix radio, restoring from a twrp backup does not fix the radio. home button stops working aswell but it doesnt work in twrp either. is there any way i can fix these problems?

Yeah, ï believe purefusion is based on the nougat firmware so that explains the loss of radio. Check the specs before flashing.......maximus, leedroid or viper should work fine.

You have to read more mate, just checked the OP of the AOSP rom.......
It says it needs N or MM firmware so no O (oreo) firmware.

Especially going from stock sense to an AOSP style rom it's wise to wipe the whole thing because you don't want to mix two roms, strange behavior may occur.
Follow the instructions in the specific thread, if you want to run the phone unencrypted then you need to format data indeed.

Hey sorry to hijack thread but I'm having a similar issue, any sort of flashing I do results in the airplane mode getting stuck to "turning off" and I can't use my mobile network. I can flash my official T-Mobile RUU zip and things will work fine, but if I flash twrp on official it breaks. I switched over to the unlocked Dev rom and it breaks. I can only get my official zip working. Any help?
My specs are:
Android 7.0
2.51.617.32
S-off locked
1.0.U010241a 6117.76.02_f radio
Switched cid to bs_us01 or whatever the Dev cid is. For the rom. Other than lineageOS which didn't work, I haven't tried any other rom except dev.

Just as all the other comments, read what you are flashing and which roms.
Nougat firmware - nougat roms
Oreo firmware - oreo roms
You have NOUGAT firmware so ONLY nougat roms work.

Nougat firmware - nougat roms
Oreo firmware - oreo roms
You have NOUGAT firmware so ONLY nougat roms work.

I am flashing nougat roms, the wwe/dev rom I have running atm(which is giving me airplane issues) is the same as the official T-Mobile ruu I have that works, only difference is that it's the dev edition instead of t-mobile, same firmware and both are Android 7.0. Flashing full RUU and not any of these custom roms on here. I had only flashed lineage to see what it was like But got rid of it and put on my working T-Mobile ruu.
Both T-Mobile and dev edition RUU is taken from the official HTC website, they're the exact same thing.

Here you can find the original firmware files. Latest one will be Android 8.1 Oreo. There will be no security patches.

It is... Flash it via TWRP after wiping your device and profit. Think about that´s a factory image with own recovery, lost root etc... And sorry for my ignorance - but as a senior XDA member you should know how to flash original firmware...
