[Q] Need help with forgotten pattern - Eee Pad Transformer Q&A, Help & Troubleshooting

Hi, my friend gave me his TF. His brother locked his device . Bot now, he doesn't remember his password, recovery doesn't work (Power, Vol Down, then UP - appears loading bar and next "dead" android.) Also I have tried to remove lock with ADB. I installed drivers, but ADB can't find the device (I'm not sure if he turned on USB Debugging). Finally, I used EasyFlasher. I downloaded stock FW, turned in APX mode, flasher gave me information "done" but it is still the same.
Any other solutions?
Thanks

You need to do a factory reset. Don't enter recovery, just hold VOL DOWN and POWER for 12-15 seconds. On the next screen navigate to WIPE DATA using the volume keys and confirm this.
It will wipe the data.

For future reference, if you had ADB enabled, you could have removed the lock without wiping data. http://forum.xda-developers.com/showthread.php?t=1800799

[Q] Nexus S not appearing in device manager in fastboot

I'm attempting to flash clockwork recovery and can't get the phone to respond to fastboot devices when in fastboot mode. I've tried everything I can find with regards to the drivers (pdanet, usbdeview, etc) and I can get google's and pdanet's drivers working fine with the phone booted normally (responds to adb devices). The problem seems to be that windows appears not to even notice that the phone is plugged in in fastboot mode and does not appear in the device manager, making the manual installation of drivers an impossibility.
Anyone know how to fix this?

When I first set up ADB and Fastboot on my pc, I was getting a response when writing 'adb devices' in the console. However, 'fastboot devices' returned absolutely nothing.
Solution (with phone connected to pc and usb debugging cheched):
1-shut down the phone
2-press and hold Volume Up key + Power
3-once in bootloader interface, in the pc command prompt, type 'fastboot devices'.
Voila!
By the way, don't mount the phone as usb storage device.
Thanks for the responses guys but yes, USB debugging is enabled and yes, I've used that way to get to fastboot mode as well as adb reboot bootloader
Hi stoo
I have a same issue - did you managed to find solution for yours?

Have the same problem: locked bootloader, not rooted 4.1.2. In ADB everything is ok, drivers ok (in device manager), can get it through "adb devices". But when I boot in fastboot (adb reboot bootloader), I hear the ti-da windows sound (usb unpluged - from adb session), but no ta-di when the phone re-boot in fastboot. No exclamation mark in device manager, nothing. The USB receive nothing when in fastboot. Is it possible that the fastboot image is corrupted? Can I reflash it? Or any other advice?
Thanks
EDIT - SOLVED - at least this step
The problem was the famous "broken power button"! I knew that I had problems with the power button (didn't work - that's why I try to flash a rom (4.2.1 or customized) with sleep tile in notification area).
I thought that the button is all the time OFF and don't switch to ON, but I finally understood that when when I boot in fastmode it freeze before installing device on the PC (I also had no volume up / down navigation in fastboot, a sign that it was frozen). So I ended to consider that the power button was permanently in ON position. I opened my phone and I measure the impedance on the power button. I had ~ 4ohms in off position of the button and 1.8 ohms (cheap multimetter.... probably should be almost 0) in on position. I measured also on volume switch where I had ~ infinite on off position, so I concluded that the button if blocked. I tried to see if I can resurrect it but no choice, so I took it off (unsoldered). I put the battery and the USB cable and boot it. From ADB I reboot it in fastboot and voila! The device popped in device manager! One problem solved! BUT...
I tried to use the Nexus Root Toolkit and it boots in fastmode and try to unlock the bootloader, but it asked me on phone screen if I agree for unlocking. I was able to use the volume to select Yes but I couldn't choose it with power! I had no option but to take the battery off. Starting from that point it was almost impossible to power it again. When I plugged the USB it shown the battery icon (charging). I tried every trick that I found on web, but nothing worked (even to fast plug / unplug many times the USB to overcharge it, but nothing). I was able only by pressing on the middle of volume (so Up and DOWN in the same time) and plus the USB to get to the screen of unlocking bootloader, but without the options YES/NO on the screen. Seems that it saves this state between boots, but why no option? Finally I was unable to boot at all, and it is like totally bricked
I thought that the power button is a simple switch ON / OFF, so I soldered 2 wires and I tried to touch them (short circuit) to simulate the ON, but nothing happened. Is it the button more complex that a simple switch? no ideea...
So now have a better phone than before (at least theoretically it should be able to fastboot), but it values zero because I can't power it on....
OK So I am in the exact same situation.
Nexus S, Broken power button, adb can see the device, fastboot cannot. fastboot cannot be navigated with the volume keys.
I also want to put an other rom onto it, but firstly I want to put TWRP recovery on it, as it supports touch, CW needs the power
button which like mentioned does not work.
I would rather not unsolder my power button to get into fastboot, any suggestions on how that might still be achieved?
thx

Yes, it should have been better for me to have also a possibility to enter in fastboot with the power button blocked in ON position, but I didn't find. And now I know no way how to power it up...

install drivers from the drivers directory and install

After you use the volume down key to highlight "Fastboot", do you then press the volume up key to select it? If you just sit there and wait it will reboot normally. You must press the volume up key after you've highlighted the menu option.

try this,
-install adb on your pc
-plug in phone when powered up
- open a command prompt in your adb dir
- type in: adb devices then enter. it should show your phone in the prompt. also check your phone, there may be a popup to acknowledge.
- rerun adb devices until it shows your phone properly or you cant proceed
-now type in: adb reboot bootloader
if it works, the phone should reboot to the fastboot screen.
if it doesnt stick in fastboot, im sorry but i dont know what else to tell you to try.
Thank-you for the Response

That's the entry to stock recovery. You have to push a combination of buttons from there to get into recovery. I forget the button combination, it has been posted many times, try searching or wait for someone else to jump in with the answer.

Not sure where to post this question been reading so many post my eyes are tired......
- XT926 upgraded to kitkat 183.46 last week via flash in RSD from JB 4.1.2
- Root went well DONE (Towel root .apk)
- Unlock went well DONE (Motopocalypse .apk) yes fastboot shows the #3
- Flashed TWRP 2.7.1 DONE (did it using the adb in motopocolypse)
- Backed up my current stock ROM in TWRP seemed to go well the program confirmed the backup was successful...So I thought
- Got confident and wanted to try flashing CM11 (Kitkat version)
- After flashing CM11 my phone got stuck at boot like many others have.... no problem I backed up my stock ROM in TWRP.....So I thought
- Went to restore my stock ROM using TWRP and yup you guessed it like many others the restore failed half way through
Not a big deal starting fresh can be a good thing BUT I really need my old text messages and all I have is a USB backup of the phone (Internal/SDcard) on my PC and of course the TWRP back-up on the SDcard that won’t restore ...... Is there any way to get these messages back to my phone????

Not sure how to help you with your immediate problem at hand, but going forward, I definitely recommend the sms backup + from the Google Play Store. Nice thing with that app is, you can link it to your gmail account, and all your text messages are backed up to your gmail.

Screen turns off after entering PIN

Hello guys,
I just replaced screen on my 64GB OPO. Phone was fine before screen broke and I had a PIN lock on it. Now, when I turn on phone, I cannot do anything on my phone besides pulling down notification bar and swipe notifications. If I try to unlock by entering my PIN, screen turns off right after. If I enter wrong PIN, it will say Wrong PIN, but as soon as I enter right PIN, screen turns off.
I'm not sure why this is happening. I decided to boot into recovery and reflash the ROM. I hold Power + Vol Down, but phone starts booting normally, no recovery. Then, I try to go into Fastboot by Power + Vol UP, and phone boots normally, no fastboot. At this point, I cannot access recovery or fastboot. Then, I try ADB on laptop, I get "Unauthorized." I can't authorize ADB RSA dialog on my phone because as I said, when I enter my PIN to unlock my phone, screen turns off. Recovery, Fastboot, and ADB worked perfectly before replacing screen.
Anyone know how to fix this?. Thank you
TL;DR:
Replaced screen. Entering my PIN turns screen off immediately. No recovery, No fastboot, ADB gives "Unauthorized" Error.

You can use this,it does not uses fastboot and instead uses hardware debugging port.
Also using this on Xp system will make it easier to detect the device.

I looked at that tool before I made this thread and in 3rd step, it says to press Power + Vol Up? Doesn't that mean you have to be in fastboot? Anyway, I tried it in Windows 10 and it didn't do anything. My phone gets detected by my laptop and everything. I will try in Windows XP and see if anything changes.

No, power+vol+ is actually done to trigger the qualcomm port,if your device can't boot to fastboot,it means it's actually dead then your pc should be able to detect it as "Qhs_bulk" or "usb qcom diagnostics 9006".
Make sure you install the drivers given in the thread or Qualcomm 2012 drivers.Again this procedure doesn't work on fastboot/adb drivers!
You'll have to disable driver signature check on win8/10,Xp works without any issues.

[Resolved] [HELP] Phone not reacting, power button broken

Hi,
I have a problem with my Motorola Moto G4. I bought it 2 months ago and unfortunately the power button broke and I am therefore not able to turn my phone on/off. That is in general not a problem since the device is still under warranty and I will get the phone repaired. The problem is that I want to backup my data, which I am not able to, before getting the device repaired since the workshop will reset the phone.
I am still able to unlock the phone but no apps or windows can be opened (taping on an app icon does not do anything). Dragging down the notification bar is possible and if connected via USB I can still see the status, unfortunately I am not able to change the setting from charging only to data connection. Since the power button is broken I am not able to reboot the device. I tried to use the adb tools to reboot but the device is not authorized and I would need to change that on the phone which I am not able to. Is there any way to reboot the phone or to access the data.
Any help would be really appreciated.
you might be able to try the commands for adb reboot recovery as the phone is booting up - iv never tried it but adb should be working after the moto splash screen (during the boot animation)
Im not sure if it needs authorisation during that stage but if you cant get into recovery and you cant change the usb connection/authorise adb then I cant see any other way to get the data off

If I would drain the battery to "shut down" the phone, would there be a way to turn the phone on without the power button?

with older samsung devices you could use a usb jig to get into download mode without the power button (its a usb cable with some pins crossed you can buy them for only £1 off amazon/ebay)
even if it did work you would still need the power button to select the option to restart phone so the answer is nothing that I can think of

I found some mechanisms to get the phone turned on and I will try them out. I guess I have nothing to lose.
The interesting thing is that my phone is still receiving messages and news (I see them in the notification bar), so things like that are still working but unfortunately new "widows" can't be opened.
Thank you for your help.
I was able to get the phone rebooted and after the restart everything works as it should.
This is what I did:
Drain the battery (using the flash light), once the battery is flat connect the phone to the PC
Press and hold the volume down button until the Fastboot menu appears
Download ADB tools (the minimal version with adb and fastboot is sufficient)
Install the Motorola driver on the PC (I was not aware that I need this, since connecting the phone without the driver being installed and running adb device results in the device being shown)
run fastboot reboot

Pixel Stuck in Bootloop, ADB Unauthorized, Bootloader Unlocked

Hello, I recently came on a pixel phone to build and use lineageOS on. Upon rebuilding, I believe I performed adb sync wrong the device and damaged system. After that, my adb keys became unauthorized and I am unable to access the bootloader menu(I press power and volume, but phone boots into Bootloop). I tried the steps to get to bootloader menu, but the phone doesn't power completely off, and when I press the power button it gives me the launch screen saying press power to pause/continue boot, not allowing me to go into bootloader
My bootloop goes like this: Bootloader integrity screen(bootloader unlocked, cannot be verified) --> Google loading screen --> Android recovery. This shows 2 options with the message, "Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device". The two options are to try again or data reset.
I press try again, and the same bootloop ensues, sometimes getting to lineage loading logo, but then back to the same recovery error regardless. If I press the buttons(power and vol up), to go into recovery, it just shows an android with a warning sign above it, giving a message saying "Error!" on the bottom. My adb on the computer shows as unauthorized, so I don't know how I can fix this. Google has said the warranty is expired and cannot do anything to help. Ideas to fix? Thanks for help in advance!
Use power and volume down (not up) to go into Fastboot mode. Then flash the stock images

I tried that, but whenever I press any button, the phone is never turning completely off unless it dies. Even after that, it goes to the screen showing the secure boot integrity(Press power to continue/stop boot)
How can I completely shut off the device and restart it? And if system is messed up, will that leave my bootloader intact(I'm assuming so as boot is a different partition?)

Does holding down the power button for 5-10 seconds turn it off? Or if you do that does it appear to turn off and then restart?
If that fails to turn it off, try just holding power and volume down for 5 seconds, and if the screen flashes (goes off and then on) let go of the power button but keep holding volume down and hopefully it goes into Fastboot.
That should work unless you have a dodgy power or volume button. The bootloader is completely separate to the boot partition, and the fact that it's doing anything at all suggests that it's still functioning.
Only other option I can think of is trying ADB commands when it's in recovery mode, e.g. adb reboot bootloader. However, if you have the stock recovery, that may not work.

Thank You!!! It didn't work in the bootloop, so I had to let the phone drain its battery and shut itself off, then I was able to enter the bootloader and reinstall lineage. Thanks so much!

If I press the buttons(power and vol up), to go into recovery, it just shows an android with a warning sign above it, giving a message saying "Error!" on the bottom. My adb on the computer shows as unauthorized, so I don't know how I can fix this. Google has said the warranty is expired and cannot do anything to help. Ideas to fix? Thanks for help in advance!

Is ur bootloader unlocked? If so, use twrp to perform a full wipe and install from twrp as well. Of you can't access trwp, and are in a bootloop, do the same thing I did: let the phone lose all it's battery, so it's outta the loop, connect the phone to a charger, then hold power and volume down. This should get you into bootloader mode where you can then use fastboot to flash twrp.
