I have problem w my t-mobile G2! It restarted by himself and then entered the boot menu.... where i can do nothing
When i press vol down button it freezses on same screen but w different options...
fastboot
recovery
factory reset
simlock
system info
image crc
where also i can do nothing!!
Can anyone help? did someone had same or similar issue?
Is it possible that no one had simmilar problem?!
Could be the recovery... You dont seem to have eng. Hboot so are you able to somehow boot in to a rom and change recovery there?
Otherthing that could be is that your emmc chip is fried.
Is there any help?
you could try to use fastboot to boot in to the rom (power + trakepad)
...connect to pc and type "fastboot oem boot" (credits to nipqer - he posted it in a different thread)
EDIT: if the emmc chip is fried you can only hope for warranty
Could you describe little closer...not so good vith all that... type fast oem boot .... where? in command prompt?
ok ...yeah you have to use command prompt, but first you have to install fastboot on your pc (goolge for the fastboot files you need)
and if you are lucky you are able to boot in to the rom. good luck
pls hit the thanks button if this was helpful
I made it... i just needed to instal android 1.0 drivers... and then fastboot oem boot did it... its working now
also instaled 2.3 update... but problem is ... every time i switch it off... even when it finished installation of 2.3 it freezes in that same boot menu... and i have to fastboot it from pc?! What's wrong?
Try a different recovery. 4ext recovery works fine for me...

Can i use it if my phone is not rooted?! I made it to temp root... but cant downgrade to 2.2. so i can do a perm root.
hm, your phone needs to have root to install a custom recovery. but in your first post the pictures shows s-off and 0.76.2000 hboot, you are sure your phone isn´t rooted?
if you still have the problem mentioned, try to wipe cache or do a factory reset. enter recovery through bootloader to do this... if you still can´t do this wipe cache through fastboot (google for the command - i don´t remember it right now - it´s something like "fastboot erase cache" but i´m not sure)

If you're stuck at dual core logo, hold volume up and power to reboot, then once you see the dual core logo, count to 3 then press volume down. If done right you'll see android recovery in the top corner, if not you may see "starting fastboot protocol," press volume down again till you see "android recovery" then press volume up to load recovery and restore your device.

Hey guys, I had Lollipop 5.0 and I did stock rom flash in Nexus Root Toolkit to install 5.0.1, everything went smoothly and it started to boot, I waited for more than 20 minutes. Then I decided to do it again and it was really hard to get into fastboot, I had to disconnect the battery and try for some more time. When I finnaly get into fastboot mode I have tried reinstalling 5.0.1, installing 5.0, 4.4.4 and even Cyanogen's last nightly. With any of those I had no luck as it is stuck with boot animation.
Some googling told me about people who did fastboot oem lock and it booted up, just tried that with no luck also.
One very important thing, when I get into fastboot mode, I can only select Start in the device itself, clicking volume up or down doesn't give me any other option.
Edit: I even downgraded Nexus Root Toolkit from 1.9.9 to 1.8.2 thinking it was the problem, no luck. And tried to install Lollipop manually a couple of times. And the problem trying to get into fastboot mode keeps happening.
Thank you all in advance
And now that I tried to lock the bootloader I can't unlock it again because when I go to fastboot mode I can only press start, pressing the volume keys doesn't do anything. What can I do to unlock the bootloader ? I think I'm stuck in here because I can't do anything else without it unlocked.
Edit: It didn't work to boot the system also
I really need some help here
so your volume down key is working when you're entering bootloader mode, but after "fastboot oem unlock" command you can't choose "YES" with the same volume down key ?

All my keys are working just fine, I can easily boot into bootloader (I was doing Power + Volume Down when I should push Power + Volume Down + Volume UP) but when I get into bootloader/fastboot (I don't know which one is the proper name) I can't do anything but press the Power button, meaning that I can only choose START. When I do the fastboot oem unlock command I can't press Volume UP or Down to choose Yes.
I followed this tutorial (http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060) with no luck aswell, I finnaly got into the system, but I can't unlock the bootloader because of the Volume keys problem. I also noticed that even when I'm into the system from that tutorial, which is Jelly Bean btw I still can't use the volume keys.
Basically, phone only recognises volume keys when it's off and I press to go into bootloader or download mode.

Hi Guys. I was trying to install TWRP recovery on my p9 lite (VNS-L31). The bootloader is unlocked, and so i downloaded the adb tool to flash the twrp recovery IMG to my phone. But once I enter the command adb reboot bootloader, the PC can't fiend my phone anymore. When I type adb devices, I doesn't appear anymore... Any suggestions??

You need to be in fastboot mode
Adb comand is not use on fastboot mode...
Just install adb driver on your PC.
download here
But how did you unlock your bootloader?
if u already in fastboot mod
don't used adb devices
use fastboot devices

There is no need to unlock it again, I can enter the bootloader and it says unlocked, and also Everytime I boot my phone it says "device unlocked and unsecure
I then get the option to eighter boot normal or enter erecovery

Chibbo is right.
Unlock bootloader again even if it already indicates unlocked.
This warning "bug" (bootloader already unlocked blabla...)
It normal after each big update to unlock bootloader again.
Right now I feel really stupid... I don't know what happened, and I did not unlock the bootloader again( I tried but it told me it was already unlocked) I can now use the / fastboot flash recovery command and it also tells me that the install was completed after 1.03 sec. But when I try to enter recovery my phone gets stuck on a site saying
Warning : Device unlocked and can't be trusted
---------------------------------------------------------------------
Your device is booting now...
I then have to press the power and volume button to get back to standard boot menu.
What is going on with my phone???

So you flashed twrp. Okay, you can try press power until phone restarts and when phone restart press volume up. You need to press it after vibration. And hold volume up until on screen appear "Your device booting now..." and phone should boot in recovery.
Or
You can do it from cmd. Boot phone to fastboot > conect phone > open cmd where you flashed recovery > type command "fastboot reboot recovery name_of_recovery.img"(recovery.img mast be in folder where is cmd to do that).
See if this helped you.
