Samsung Firmware Downgrade T-Mobile Galaxy Note 2
Samsung Galaxy Note 2 Temporary Firmware downgrade to Successful Unlock (SGH-i317 & T-889 models supported)
Disclaimer! Please Read Before Proceeding:
Please note: This method has been proven to work because it uses Samsung’s Official programs and the Official stock T-mobile provided Images. As with any Official carrier or manufacturer firmware flashing this must be done at Your Own Discretion. The instructions are outlined CLEARLY and you MUST follow the instructions EXACTLY. If any issues arise we cannot take responsibility for any issues but we can definitely help you out. If you do not want to proceed, unfortunately we are unable to provide refunds as stated on our website before ordering. Please contact us for more information.
If you still wish to unlock your Galaxy Note 2 please proceed:
Due to a recent firmware update that which T-mobile and AT&T released to all their NOTE 2 owners the devices have all been rendered non-unlockable or rather difficult to unlock as it automatically changes critical system files. As of now, there are no other unlock suppliers who can unlock 4.1.2 or 4.1.1 UVALL8 Baseband/Version Note 2’s. However, this method will get you back to the previous STOCK firmware and baseband which allows unlocking again with us at Cellunlocker.net.
