Sign petition to Asus unlock APX in Asus Tablets

Sign petition to Asus unlock APX in Asus Transformer Prime, TF300T & Infinity! Sign it! Link to petiton:

https://www.change.org/petitions/asus-nvidia-revert-changes-in-jb-bootloader-that-prevent-nvflash

Dear ASUS/Nvidia,

We are owners and prospective owners of an Asus Transformer Series Tablet. However, we were very disappointed that the JB bootloader prevents NVFlash.

While we trust that the TF201/TF300/TF700 will be well-supported with official updates, this tablets have the potential to be an excellent platform for development enthusiasts as well, and we think NVFlash would make them even more attractive for developers and customers.

In the past we had already been able to use NVFlash which saved many devices from a brick and buying a new (maybe Non-Asus) tablet.

Please consider giving us the ability to use the NVFlash tool on the TF201/TF300/TF700 again. We assure that this will establish ASUS’ reputation in the community as an excellent and receptive supplier of mobile devices.

Yours faithfully,
The Undersigned

[GUIDE] nvFlash General Users Guide [Unbrick/Recover/Downgrade/Upgrade]- TF201

AIM: This is a general users guide to unbrick, recover, downgrade or upgrade using nvFlash for the Transformer Prime TF201. I will try my best to help anyone out so please feel free to PM me if you have any questions.

REQUIREMENTS:
1. Transformer Prime TF201 (duh!!!)
2. Enabled nvFlash access (Tegra 3 nvFlash by AndroidRoot)
3. Window or Linux computer [Linux recommended]
4. Ability to use a command prompt or terminal shell
5. nVidia APX drivers [Windows Only] (Universal Naked Drivers)
6. Wheelie & nvFlash binaries/executables
7. You device specific nvFlash backup files generated while enabling nvFlash

THIS GUIDE COVERS:
1. Manual steps for basic unbrick, recovery, downgrade or upgrade. [Windows & Linux] This is your first option to recover your device.
2. Automated complete factory reset & recovery [Linux Only] Use this only if you cannot recover using the manual steps or if you want to completely wipe and recover your device.

IMPORTANT INFORMATION:
At the moment, nvFlash can only be enabled on a device with the 9.4.2.28 ICS bootloader. If you have upgraded to the official Jelly Bean ROM before enabling nvFlash, you would have the new 10.4.2.15 bootloader and you will no longer be able to enable nvFlash. When following this guide, read the information provided carefully to prevent any permanent damages. Be patient as each step may take a while to complete. Make sure your device is charged (recommended more that 75% battery) before attempting anything detailed here. Do not forcefully power off your device at the wrong time. Keep you device connected to your computer during the whole process. If you encounter bootloops or are stuck at the Asus spinning wheel after this process, a data wipe should fix this (Power + Vol Down, then select Wipe Data)

WHY ENABLE NVFLASH:
nvFlash would allow you to recover your device from almost any brick and would allow you to upgrade or downgrade your device.

SETUP:
1. Download the nvFlash binary/executable for your operating system [ Windows / Linux ]
2. Download the wheelie binary/executable for your operating system [ Windows / Linux ]
3. Install the APX drivers [ Windows Only ]

FOR LINUX USERS:
Make sure you always run nvflash and wheelie as root or sudo. If your user does not have root privileges or is not a sudoer, you will quite likely not be able to do this. If you are a root user, do not use the sudo prefix in the commands below.

INSTRUCTIONS [MANUAL STEPS]:
1. Download an un-blob’d ROM (links below). [Advanced users can use BlobTools (blobunpack) and unblob a ROM. Make sure you have compatible unblob’d images of the bootloader, recovery, kernel & system]
2. Extract wheelie, nvFlash and the unblob’d ROM to a directory (avoid spaces in the directory path)
3. Start your device in APX mode [Power On + Volume Up]. Your tablet screen will remain blank in APX mode.
4. Bootstrap your device (enter nvFlash mode) while your device is in APX mode using wheelie

Quote:
Windows:

Code:
wheelie.exe --blob blob.bin

Linux:

Code:
sudo ./wheelie --blob blob.bin

5. After wheelie does it’s job, your device will be ready in nvFlash mode. You can now begin the process.
6. We start with the bootloader. In the case of the un-blob’d ROMs below, this is the blob.EBT file. To flash the bootloader, use this command:

Quote:
Windows:

Code:
nvflash.exe -r --download 4 blob.EBT

Linux:

Code:
sudo ./nvflash -r --download 4 blob.EBT

7. Next we move to the recovery image. In the case of the un-blob’d ROMs below, this is the blob.SOS file. To flash the recovery image, use this command:

Quote:
Windows:

Code:
nvflash.exe -r --download 5 blob.SOS

Linux:

Code:
sudo ./nvflash -r --download 5 blob.SOS

8. Next we move to the boot image. In the case of the un-blob’d ROMs below, this is the blob.LNX file. To flash the boot image, use this command:

Quote:
Windows:

Code:
nvflash.exe -r --download 6 blob.LNX

Linux:

Code:
sudo ./nvflash -r --download 6 blob.LNX

9. Next we move to the system image. In the case of the un-blob’d ROMs below, this is the blob.APP file. To flash the system image, use this command:

Quote:
Windows:

Code:
nvflash.exe -r --download 10 blob.APP

Linux:

Code:
sudo ./nvflash -r --download 10 blob.APP

10. Finally, we reboot the device. After you run the following command, you will see the text “AndroidRoot 9.4.2.28” and your device should reboot in a few seconds. If you device does not reboot after you see the text, force a reboot (long press the Power button)

Quote:
Windows:

Code:
nvflash.exe -r --go

Linux:

Code:
sudo ./nvflash -r --go

SEMI-AUTOMATED COMPLETE RECOVERY – LINUX ONLY:
This process completely wipes all partitions (except external SD/mSD cards) and reflashes everything, essentially returning your device to a near factory state. You will not lose you unlock status or nvFlash access. You will lose all data from your internal storage (/storage/sdcard0 or /data/media).
Unfortunately, due to technical reason, this process is possible only using Linux, since the nvflash executable for Windows is very old and cannot handle this process. I will be creating a detailed step-by-step guide for those not comfortable with Linux. But for now, this is available for all those who know how to use Linux.
To use this, you need to download one of the unblob’d stock ROMs below (or create your own) along with the semi-automated complete recovery zip below.
You will also need the device specific nvFlash backup generated when you enabled nvFlash.
Complete instruction are in the “README” file in the semi-automated complete recovery zip.

DISCLAIMER: nvFlash can save your device, but if used incorrectly, it could permanently brick your device. If you follow the instructions carefully, you should not have any problems. However, in the event that you do have a problem, neither I (craigacgomez), nor the AndroidRoot team can be held responsible. Use this guide at your own discretion. If you need help or do not understand something, PM me and I will try to help you as much as I can.

Como Instalar Rom Oficial en Samsung Galaxy Ace

Al igual que la mayoria de los samsung nuevos, en galaxy Ace nos encontramos con un metodo sencillo y rapido de flasheo sin tener que complicarnos la vida con lios de muchos pasos. En este tutorial se explica de manera textual y audiovisual el procedimiento a seguir.

Notas: Al flashear el Galaxy ACE obtendrás mejor respuesta en general así como se eliminaran las aplicaciones que vienen de fabrica por parte de ru proveedor de telefonía celular. Tus fotos y datos que estén en tu SD externa no se verán afectados pero todos los datos de la SD interna si se verán afectados y por eso es recomendable respaldar o en caso de que quieras comenzar desde cero, no respaldes y a darle.

Nota para usuarios 3g en banda 850mhz: Para los usuarios de una telefonía de latino america que utilice la banda 850mhz para la señal 3g. Es recomendable que si tienes plan de datos actives la banda 850 con  ESTE METODO el cual tambien corrige los errores del wifi que tienen algunos firmwares.

Al dia de hoy 25/marzo/2012 y en adelante puedes entrar a  SAMMOBILE a descargar la versión mas reciente las cuales están citadas por fecha en esta direccion 

ACTUALIZAR 2.2.1 2.3.3, 2.3.4, 2.3.5, 2.3.6 etc

LO QUE NECESITAREMOS

  1. Descargar una rom  de samfirmware (para este tutorial usamos la mas nueva S5830XXKPH pero tu puedes usar la mas reciente, el procedimiento será el mismo))
  2. Descomprimimos la rom (Si te pide contraseña prueba con  samfirmware.com o con sammobile.com )
  3. Descargamos ODIN para flashear ACE (es parecido pero no igual a los otros odin)
  4. Tener instalado (pero  cerrado) KIES o tener instalados los drivers (descarga aquí)
  5. Utilizaremos el cable de datos
LOS PASOS SON
  1. Abrir odin y colocar en cada casilla los archivos a flashear(los que salieron despues de descomprimir el archivo)
  2. Apagar el celular
  3. (Opcional) encenderlo en modo recovery y elejir  wippe all, yes y wippe data yes.  Reboot now y sin dejar que inicie al momento de apagarse la pantalla presionar los botones para que entre en modo download
  4. Encenderlo en modo download
  5. Conectar el celular y esperar a que ODIN marque conectado COM:
  6. Dar clic en START y esperar de 3 a 10 minutos
  7. el celular se reinicia y comienza a iniciar el nuevo android. En odin verán una leyenda PASSED o FINISHED y podrán descoenctar el cable de datos.
——————–Para ser ROOT en froyo y gingerbread
Si quieres ser ROOT
Para hacerte root, si instalaste una versión Froyo  puedes bajarte  SuperOneClic, lo descomprimes y abres el ejecutable, colocas tu celular en modo de depuración (Entra en CONFIGURACIÓN/AJUSTES + APLICACIONES + DESARROLLO + Activar depuración USB) y conecta el celular a tu computadora.
despues de que se instalan los drivers OPRIMES ROOT
Si instalaste 2.3.3 o 2.3.4 Gingerbread no se podrá hacer root por Superoneclic pero si se podrá por otro método.
Lo que tendrémos que hacer es buscar un kernel compatible con la versión de android instalada y lo flashearemos con odin solamente seleccionando PDA
Al terminar esto tu celular queda con una rom europea y en europa utilizan redes distintas a las de america para el internet movil, asi que si tienes contrato de datos tienes dos opciones una para usar el celular como queda y a otra para configurar el modem del celular para detectar la señal 3g.
  • La primera es en conectividad redes cambiar a solo usar redes 2g. (con esto ahorrarán mucha batería)
  • la segunda es flashear un modem que soporte banda 850
Nota: si no tienes plan de datos, no es necesario que hagas el flasheo a una banda 850, pero si es necesario que establescas que tu celular se conecte solo en redes 2G. Ya que si activas usar redes 3G como la rom que se metió es de Europa, estarás forzando el celular a buscar señal 3g y no la va a encontrar y esto te provocará pantallazos de apagado o encendido (no te asustes no se está muriendo ni nada por el estilo) entonces solo entra a configuracion/ajustes + conexiones inalambricas + Redes moviles + Modo de red y selecciona 2G o GSM.
