SM-G910A - Any hope? - GSM-Forum

I have an AT&T Note 4 that I have had no luck in repairing. This is my last shot before I sell it for parts. I know there have been other threads dealing with some of these issues, but this on is even more messed up. It got to this point by either entering *#9090# or downgrading firmware (or both) , but here are the facts of where I am now:

1. Will not boot on any version of Lollipop. It gets to Android is Updating and restarts after a couple of seconds.

2. I downgraded to 4.4.4 (N910AATT1ANIE) and the phone boots, but unknown IMEI and baseband. phone is very laggy and restarts after about 30-40 seconds.

3. Phone will not load MTP Driver, and ADB does not see the phone even after USB debugging checked. Therefore I cannot temp root and use bsisco's method.

4. I've tried a couple of repair shops, but they haven't a clue.

I can get to download and recovery modes.

Any ideas would be greatly appreciated.

Can you root the phone during the time that its running on 4.4.4? If so there is a fix. If not...there might be a fix through Odin, but I really doubt itll work through download mode.

There is one way that might bring back your baseband and it's via download mode, don't have the corresponding file if not I'd give it ..

Please send file, at this point it can't hurt to try. Thanks so much.

I'm on that situation, and pass that failture of android system because it's has no baseband + imei

just do it as fast as you can

Pre-req: on 4.4.4 ALL_ATT_N910AUCU1ANIE_N910AATT1ANIE_CL2774708_QB23 73670_REV00_user_low_ship_MULTI_CERT.tar

1. conect to a wifi network (may be you'll receive some reboot while doing these step)
2. Enable debuging option and allow debuging from adb shell
3. Download and install KingRoot-4.0.0.233-release-201505071219_105001.apk (google for this file, must be this file)
4. open and getroot (in this step will fail sometime, but just try again and do as fast as you can)
5 when you see root success, now we go with adb shell

you only have 40s or 60s to do with kingroot and work with adb, so just copy and paste this command and paste into comandline and remember grant su request when you type "su"

Code:

adb shell
su
dd if=/dev/zero of=/dev/block/mmcblk0p10
dd if=/dev/zero of=/dev/block/mmcblk0p13
dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p15
dd if=/dev/zero of=/dev/block/mmcblk0p16

after this, your baseband will come back and not reboot, now you can work around with imei via cert writing

This method already tested and success, you can see screenshot here http://vietfones.vn/forum/showthread...lock-repair-ok

Thanks, but unfortunately this won't work for me because adb is not seeing phone.
