[Q] Problem downgrade from 4.4 to any version - Android Q&A, Help & Troubleshooting

Hello to all, this is my first post and thread, I hope everyone is ok.
Well just yesterday I updated my samsung s3 to a kitkat 4.4, it is a custom version and I do not like it and decided to downgrade it to a 4.1.2, but I have tried several times and I cannot do it
I have used, odin 3.07 and 3.09, lastest version of twrp and cwm recovery and nothing, the twrp log file is attached.
I will appreciate some help, I can only install the 4.4 kitkat but I want to go back to any version, I have 4.1.2, 4.2.2 and 4.3 and none of them work.

[Q] S3 cannot reboot after install a older version of stock rom?

I update my s3 to android 4.1.1 yesterday. Then I saw a leaked rom android 4.1.2 in sammobile today. I installed it and found out that it has a lot of bugs. I tried to install android 4.1.1 back and after install, my phone cannot boot. What should I do?
One more thing, I can stall android 4.1.2 (the leaked rom) and can reboot. But I cannot reboot after I install android 4.1.1 rom.
try a factory reset
Thx. I fix it. :good::good::good::good:

[Q] S2 Custom Rom help!

Hey everyone, this is my first thread on this huge community. Can someone suggest me a custom ROM that can be flashed using ODIN or Mobile ODIN or via CWM 4.0.x.x? I've tried twice to install the 6.0.x.x version, but in both cases I soft bricked my device
I am searching for a Stable ROM, possibly kit kat or higher (but an improved version of Jelly Bean would be OK).
I would really like a Lollypop Custom ROM, but, as I sad before, I failed twice. Thanks for your help!

Hello,
You should update your recovery to this: http://forum.xda-developers.com/galaxy-s2/development-derivatives/kernel-t2291756
You cannot flash a kitkat or a lollipop ROM with a CWM 4.0.X.X recovery as it is very old.
Once you've installed the above mentioned latest Apolo kernel, you can go ahead and flash any other ROM normally as you would do with any other recovery.
Regards

[Q] How to update software manually? :eek:

Hello everyone, recently my friend wants to update his S3 android from 4.1.2 to 4.4, but however the OTA software update shows that the newest update has been installed
How can he get an update of android of his S3? His phone information are as below , please ignore the Chinese characters
Btw he wants to try UPSM on his phone, does he need to root his phone
Please help me
No 4.4 update was released for i9300. The last firmware is 4.3 (you can find HERE).
If he really wants 4.4 or above... yeah he needs root. The most similar ROM for i9300 version 4.4 is the back-to-n00t by arter97.
Cheers.

Thanks a lot
do I need to install a universal offical ROM to let him update from 4.1 to 4.3 via OTA?
No, if 4.1 is official just download and flash via Odin the 4.3.

Updating from 4.4.2 to 5.0.1?

I'm looking for a rooted stock rom I can flash using Mobile Odin. Any help or direction will be helpful thanks:good:
At (galaxy note 3 root dot com, sorry I cant post links until 10 post made) they have the stock firmware. I flashed that (4.3) and was back to stock. It prompted me to upgrade to 5.0 (after two 4.4 upgrades) and than I rooted. You can go that route. I have a nandriod of rooted 5.0. Best bet is to flash stock firmware from link (via odin), factory upgrade to where you want and root.
Or my advice is forget about 5.0 as it sucks and flash an aosp based rom like cm12.1 or aicp 10 (both running 5.1.1) and....blast off! I never thought I could upgrade my phone and speed it up at the same time.
I just found this http://forum.xda-developers.com/note-3-sprint/development/rom-t3132662 rooted stock 5.0
