Hello how are you? I'm from Argentina and I need some help, I have a tablet Samsung Galaxy Note 12.2 SM-P900 Pro, the upgrade to 5.0.2 Lollipop both the original firmaware or Custom ROM does not start, causes the screen bootloop "Samsung Galaxy Note Pro 12.2 ". Do HardReset with TWRP and does not solve my problem. All I could do is reinstall KitKat 4.4.2 to start the tablet properly. Anyone know how I can fix this and have Lollipop?

What do you mean by upgrade by original firmware ? How did you upgrade it ? Original firmware should replace your recovery to stock and no longer twrp if you flash the whole package . Anyway , you might not have LL bootloader installed . Grab it from https://www.androidfilehost.com/?w=files&flid=35233 and flash it via odin
First I did the update from the tablet and not start. Then from Odin install the downloaded firmware SamMobile from different regions and got the same inconveniences. Finally try custom rom installed from TWRP and the same thing happened. Also install the bootloader by Odin. By TWRP the kernel. Still the same, with lollipop installed tablet does not start, but with KitKat if you do, and no more trying.
I had similar problems with my device until I installed this guys custom Lollipop Rom

He mentions that you have to install a lollipop bootloader "included in the linked post" for it to work, and I was able to do that through odin. At first it didn't work for me, but seemed to work after I tried again.
This is a great rom by the way, it runs smooth and everything seems to function well.
There is also a Kernel for this rom you might try flashing with twrp

[ALE-L21] Software install failed when I want to install EMUI 3.1 as dload

Hello everyone!
I am newbie there so If I did something wrong then I am sorry.
I have a big problem so I so need your help (in sos?).
I am trying install back EMUI 3.1 cause 3.1 was faster and power saver than 4.0.3 so I would to install back 3.1.
I found a zip file which is contain update.app. It has been downloaded from huawei's site (c1.huawei.com). So maybe it is an offical package
I am trying install EMUI 3.1 since yesterday.. But I always got an error (Software install failed). If I install an rollback android 6 to 5 then my recovery is dies. I did everything I saw on xda and other forums.. My phone is unrooted, bootloader is unlocked everything.. I so need EMUI 3.1. :crying: Please a helpful person.
Thanks,
Balázs.
Solved
I hopefully solved the problem. Solution: Extract img files from .UPDATE app and flash it with fastboot.
You need flash boot recovery system and cui (or what is that) img with fastboot.
Now my problem is I do not have IMEI on 3.1 but on custom 4.0.3 rom I have that. So my SIM card is not reading I can't connect to network. Anyone can help me in SOS?

Idol 3 5.5 6045i

I'm looking for a stock firmware image for the idol 3 5.5 6045i. I am rooted with TWRP 2.8.7.0 on stock Android 5.0.1. In order to use the newer Androud 6 and 7 roms I need to update the stock firmware to Android 6. Any ideas? Also, is there a telegram group for this phone?
there is no stick Android 6.0 firmware. If you are rooted just install Android 6 or 7 custom roms.
Whenever I try to install those Roms, I get an error. Do I need to format the data partition and update TWRP?

Recovery image needed for Stack J107

Hi, new user here but I have been following for years the forum and had installed custom roms for my devices.
I have been gifted a Stack J107 Chinese tablet which was supposed to be running a MTK6989 deca processor with android 9 but in reality it is a MTK6592 running a lollipop 5.1.
I have tried a few custom recovery images for both chipsets but none would work.
The thing I didn't know is that I could backup the recovery via so flash (I am new to mediatek).
Does anyone have a stock recovery image that could fit the device?
Thank you in advance.

Custom ROM / Android 12

Hi,
Is there ANY custom rom i can flash coming from a A51 that is ALREADY on Android 12 stock firmware ? i got twrp installed and rooted it with magisk on the stock rom, but whatever firmware i tried (last was the pixel experience 12 unofficial) i just hang in the samsung galaxy screen for ages, and rom doesn't boot. Do i need a custom android 12 kernel too and that's why i doesn't work ? All threads i looked and searched just mention coming from Android 11.
Hello!
I want to say you, that it is impossible to flash a custom rom you want on you galaxy, when it has android 12.
I thought, that I would not be able to flash twrp on my phone with this android version, and I decided to flash android 11 first, and oonlyy then to modify the phone by flash twrp, getting root access and so one.
THE ANSWER IS NO, YOU NEED TO FLASH ANDROID 11 BINARY 5 (!) AT FIRST
