[Q]Fastboot to relock bootloader - HTC Amaze 4G

I want to unroot and go back to stock completely. I read some howto threads and they had a step about relocking the bootloader by going into fastboot. How exactly do I do that?

I tried his toolkit so many times to try to relock the bootloader but it doesn't detect my phone even if USB Debugging is check on.

You have USB debugging checked on, do you also have it set up as CHARGING ONLY, and not the SD CARD setting?
Double check these settings and report back - another possibility (I can not confirm if it is necessary or not), try booting into the bootloader screen first and then run his re-locking script.

I have it set up as Charging Only.

if your having issues with the phone being detected... try reinstalling the usb drivers then restarting your computer... and just a heads up.. don't make more then one thread pertaining to the same problem/issue with the phone.. its harder for people to offer you help/advice if they haven't seen what was said/tried before...( i believe i told this to someone already) but yes.. re-install your usb drivers from hasoon's toolkit and see.. if you want to test the adb connection use some of his shortcut commands to boot the phone into recovery or restart it

If you haven't tried resetting it manually through fastboot commands, this may work:
Reboot your phone to bootloader (power button + volume down)
Open a command window and navigate to the folder where your fastboot.exe file is located using the command "cd C:\<folder tree>"
Execute the command "fastboot oem lock"
This worked for me about an hour ago even with my computer not recognizing my phone. Hope it helps.

[Q] Help with partially bricked EVO 3D Unlocked - S-ON

Hello,
I have an EVO 3D that was having screen issues.
When I took it to the Sprint store they said my warranty was void for having ViperRom on the device.
The device was HTC unlocked and had ViperRom redline.
I asked them to not note that down and that I would come back tomorrow with the device back to stock settings.
I made a mistake though when I manually flashed a boot.img using adb.
Now I just get a blank screen when the phone starts. I am not able to enable USB debugging or disable fastboot.
Now I can get into the bootloader by using power and the down key.
Since the phone is in Unlocked Mode and S-ON I can't update through ADB without USB debugging or fastboot disabled.
Also any PG86IMG.zip on the SD card doesn't ask for an update when the phone is HTC unlocked
There is no bootloader option to relock the phone either.
If anyone can please help I would greatly appreciate it. I'm supposed to go back there today 9/18/2012 at 4PM PST
Are you able to get into fastboot on your phone? If so what you have to do is relock your bootloader first. Fastboot oem lock is the command. Your phone should pick up the pg86img file and update.

I can't relock the bootloader using any PC tools. I can get into the bootloader menu by pressing Vol- but since the phone give a black screen when I try to booth I cannot enable USB debugging nor disable fastboot. I think this is what is preventing me from being able to connect to the phone via USB... I'm working on that assumption however I could be wrong.

I can see when I turn the phone on it's actually functioning, just with a black screen. It still makes noises for receiving text and so on I just can't enable usb debugging and disable fastboot blind. I wonder if I found my HDMI adapter if an external display would work. That would be weird.

i also need to find out because i cant even get into my phone due to bootloop issues...i bought my HTC MyTouch 4G from someone & been trying to fix my bootloop, every forum says to make sure "usb debugging" is enabled but i have no idea if it is or if it isnt
also when i use "adb devices" in cmd nothing shows up under list of devices...i just hope there is a command in adb or fastboot to enable/disable usb debugging

I don't know whether you can enable USB debugging through fastboot ... i'll leave that to the experts.
However you can see your devices when connected to a PC in fastboot mode!

yeah i got that part, but when i try to flash or write anything to the device using fastboot i get nothing but errors so im guessing usb debugging must not be enabled
I'm sorry to say, you cannot enable USB Debugging through fastboot.
Hit the thanks button if i helped answer your question
Those errors have nothing to do with USB debugging. Your bootloader might not be unlocked so the flashing commands aren't working, or you're using wrong commands. USB debugging is at the ROM level and is for enabling adb while booted into the ROM. At the bootloader level, only fastboot commands work if the bootloader is unlocked. adb does not work. You need a custom recovery like CWM/TWRP for adb to work, and this recovery has to be flashed via 'fastboot flash recovery <recovery name>.img' on an unlocked bootloader.

Hello,
I'm also interested on this topic. My screen is broken, but the phone is working. I can boot and I feel the phone working and recognising my finger to unlock. However, because I'm stupid and I didn't have the "USB debugging ON" I can't access my files via ADB or any recovery software.
However, I can boot on fastboot and I see my device on "fastboot devides". Can I do something to access my files from there? I don't know... maybe unlock bootloader and flash any kind of TRWP with full adb or something like that.

As its name implies, Fastboot operates on device's bootloader and not on device's Android files as ADB does.
BTW: You always can access the user-data stored in Android's file system if USB-MTP mode got enabled on Android device.

True, I can see my Xiaomi on "Windows Explorer", but it's an empty folder because I can't select MTP mode instead of "only charge" mode that it's launched by default.
What if I flash a TWRP recovery (I'll need to open bootloader first) and then from TRWP I try adb?
It must be a solution... if profesional people can do it so we do.
Thanks.

[Q] DNA stuck in boot loop, Supercharged Hatka DNA ROM (1 Litecoin bounty for help)

Droid DNA with Supercharged Hatka DNA got stuck in bootloop after running fine for over a year (ROM flashed last February)
I have a *fairly* recent backup if I could get it to boot to recovery, but I would prefer not to considering the 20ish Litecoins walleted on the device. I will be willing to give a whole Litecoin to whoever can fix my problem

Do you have adb? If you do the command is adb reboot recovery. Need to know more it just cycles? If so then try to push both power button and and both volumes until it has lights flashing at the bottom and reboots dont let go until it reboots. Other then that I am not sure. I tried to boot to recovery the manual way and it doesnt work. Which is why i Always use that to reboot recovery. Wait, I figured it out. Hold down volume power dont let go until bootloader comes up then let go of both. use volume down and select recovery and bam!
Okay so I tried holding down power and down volume to get into bootloader, it got me there and I could scroll to recovery, but it kept cycling the reboot before it would boot into recovery. I tried plugging it into the computer to use adb, but it just makes the plug/unplug USB sound in Windows. I also tried holding down all three buttons, and it makes no difference.

Ok so if you have fastboot you should be able to use fastboot to flash recovery. If you are going to use a backup then you would need to have the same recovery image you used for the original. My suggestion is go to twrp and get the image. make sure you are plugged in at bootloader and fastboot is selected. IT should say fastboot usb if you are connected correctly on the top. I am assuming you have fastboot? If not my suggestion is to get minimal adb and fastboot it is the easiest. after you have installed run this command.
fastboot devices
it should come up with your device number if it doesnt then you need fastboot drivers. If it does then take the recovery.img you downloaded and place it in the same folder as your fastboot and adb folder. I suggest changing name to make it easier, I usually just change it to recovery.img instead of whatever it downloaded as. Then enter this command
fastboot flash recovery recovery.img
It should say sending and complete then enter this command
fastboot reboot recovery
bam you are in recovery!

ADB and fastboot don't help, since it won't connect to any computer. I'm starting to think this is a hardware issue
I figured out what caused this. About a month ago, I was deleting unnecessary files, and it had been a year since I'd flashed my custom ROM so I forgot what the process involved. I accidentally deleted the 'sdcard' folder, and the phone became a ticking time bomb for it to stop working. I bricked it didn't I?

No, If you have twrp use adb push and push a rom to your phone and then flash it and your fine.

Rooting/unlock bootloader: I've tried them all

Ok, this is getting very frustrating. I've been rooting phones since the day the G1 came out, and having gotten a v10 yesterday and tried to root it, all of a sudden I have become stupid. I have tried every type of method om this board to attempt unlocking the bootloader, rooting, and installing TWRP. I've even tried the Nexus Root Toolkit and the I-Root/V-Root methods, both on the phone and from the PC. Even though I "sometimes" am able to type "adb devices" and actually get the device #, many times, both when trying to get into bootloader mode or as with both KlicKit and NRT, it more often than not hangs at "waiting for device". Is there anybody that has had a similar type of difficulty that has figured out how to make this happen? I took it out of the box and started to do my thing, so I am assuming it has a locked bootloader? This should not be so difficult to accomplish. Any insights would be appreciated.

If you have a T-Mobile device you are able to root etc. Make sure you have usb debugging enabled, and tick enable oem unlock in developer options. I presume you have a driver issue. Just go ahead and reinstall the drivers and try again.

Hi Mark. Which drivers? I have literally tried to use 5 or 6 different ways of installing drivers: device manager/Nexus Root Toolkit/the full Android SDK/KlicKit/adb setup 1.4.3 and maybe two others. Do you know a source that I am missing? Why would my phone out of all of the thousands sold NOT have proper drivers installed? This makes no sense. Weird thing is I can get to the bootloader screen using the adb reboot bootloader command.

Can I ask what commands your running when you're rebooted into boot loader/fastboot?
I'd say to try the LG drivers first and if not go with the Samsung ones. They're relatively universal.
Im also having problems. Ive installed every driver from samsung lg google and universal drivers and still nothing. I can get adb to reconize the device and reboot my device. I type in fastboot oem unlock and it stays on waiting on device

Sure. Usually I am able to get into the bootloader(if adb devices recognized what's going on) where I get the LG logo and the words on the top left say "Welcome to Fastboot Mode". I put in adb reboot bootloader, which does get me there. Then, I put in fastboot oem unlock and that's when it hangs on waiting for device.

Exactly. I guess the "misery loves company" thing is operative here. If you do figure it out, PM me, I will do the same.
what does it say when you type "fastboot devices"?
I am 100% certain you have either a driver issue which you should look into in your device/driver manager on your pc. there's likely something broken (common problem). Or you do not have usb debugging/enable oem unlock checked. I'm leaning towards a driver issue. It is also possible that if what you say is true and have installed too many drivers that something is conflicting.

Progress!!! I was able to use Tech Know to unlock the bootloader. Now, if I can get the phone to behave enough to install twrp and root I will be good. But, KlicKit is not doing it, still hanging. And, when I type fastboot devices it just opens up another prompt and sits.
Edit: And, I am able to use fastboot reboot to reboot from the bootloader, but I get an error message when I try KlicKit, but it goes away too quickly to read what it says. OK, so now that I have an unlocked bootloader, do you have a recommendation of what method to use to install twrp and to root. (I have renamed the twrp file to "twrp.img" and I have both SU 2.46 and 2.52 on my external sd).

Just follow the instructions in the "how to root..." thread. it goes step by step and I believe there is a video tutorial as well. You'll need to do a quick search for this.

I literally figured this out 2 hours ago. It is a Driver issue but reinstalling a .exe will not work. This is what you have to do!(did this on Windows 7)
Boot up fastboot and plug into your pc.
Go into "device manager"
While in fastBoot your phone should be listed in "other devices" simply titled "Android".
You have to re select the Driver your self , do not choose for it to automatically search.
Look under the "Android devices" tab and if you have the LG drivers you should see something like "LG adb interface blah blah"
Choose that driver and fastBoot should work.
Try "fastBoot devices" in cmd it should finally recognize.
I've also heard success from selecting any "adb interface" driver
I think I'm gonna make my own thread and YouTube video to break this down further. I've also been and adroid user since the g1 and. I hate being asked "are you sure u ticked usb debugging?"

Hi Duece, thanks for that. I am ok up to where I actually try to root, meaning, I am fine with getting into the bootloader. When I type "fastboot devices" it does give me the model # and the word fastboot next to it. The bootloader is now definitely unlocked. It's the next steps (twrp/root) that I get stuck. When I use KlicKit, it does do something for a second and then it just closes. Have you successfully installed twrp and rooted? That's where I'm jammed up. Thanks...
Edit: although I have the twrp.img file on my ext sd, and I renamed it "twrp.img" and typed that command in when in the bootloader, but it says "error: cannot open twrp.img".

put the twrp.img in the same folder with fastboot, flash recovery by using
Code:
fastboot flash recovery twrp.img
After twrp flash ,shutdown/ restart to factory rest mode and go for 2x "yes". if entering TWRP fine, then flash a supersu 4.52 zip from sd
I am using 2.8.x twrp working fine

Aah, that would make sense. However, I did a search in Root Explorer and nothing came back with "fastboot". Do you know where the most likely place would be?

So which step did you go through?
Do you have your twrp recovery working now?
fastboot is a platform tool from google. You should have it downloaded to computer(Win) and use it with CMD(command prompt)

I've also heard success from selecting any "adb interface" driver
I think I'm gonna make my own thread and YouTube video to break this down further. I've also been and adroid user since the g1 and. I hate being asked "are you sure u ticked usb debugging?"

So which step did you go through?
Do you have your twrp recovery working now?
fastboot is a platform tool from google. You should have it downloaded to computer(Win) and use it with CMD(command prompt)

This is a good sample of how ppl unlcok BL and root v10

No good. typed adb reboot bootloader, it went right there. Then typed fastboot flash recovery twrp-2.8.7.1-h901.img, it gives an error message: cannot flash twrp-2.8.7.1-h901.img. Typed fastboot reboot, went right back. The video's great, but if the commands don't take, it 's moot. If anybody figured this out (same issue), please let me know how. This is taking forever.

are you sure your bootloader unlocked? and the code you typing match the recovery file name?

Positive. The code I am putting in is twrp-2.8.7.1-h901.img. That's what most things I've read say to do. The other thing I have been thinking about is that KlicKit is supposed to have everything pre-loaded, and even it won't do it. KlicKit gets me into fastboot, then something really quick happens and the command prompt screen closes. What driver system do you use? I've installed a number of them, then deleted them as well, just to try to make sure there are no conflicts. However, I now have two devices in device manager: "android device.lge mobile adb interface" and "portable devices/v10. Does one need to go, maybe?
Power off your phone , hold volumn down and connect usb to PC.
Do you see "LOCK STATE - UNLOCKED" ?
if yes, type "fastboot.exe flash recovery twrp-2.8.7.1-h901.img "

I already found the solution, but it will erase your data.
with the adb commands you must restart the device in boorloader mode:
adb reboot bootloader
Then when I take you to the bootloader screen what you have to write next:
fastboot oem lock
(Remember the phone will be erased)
then to restart the device you have to:
fastboot reboot
And the device will reboot.
what you do is lock it, so that you can then unlock it in a simple way.
(If you do not know what the ADB is, warn man), I hope it helps you and those who enter here too :good:
@l3dson: Be careful before relocking the bootloader: The phone MUST be 100% stock or you will have a brick.
@Mohammedbi: Your bootloader is still unlocked, even after flashing the KDZ. It's just the newly flashed ROM doesn't know it, and you don't need it to.
Just go to fastboot (PowerOff, Vol- while plugging in cable) and flash TWRP. Follow ChazzMatt's root guide for the initial TWRP steps.
Have anyone found the solution for this problem...

What exactly is not working?
ADB doesn't require Enable OEM Unlock to be set. Just plug it in and ADB away - unless drivers or cable or port aren't working.
And your bootloader is still unlocked if it was unlocked before you flashed stock Oreo. You should be able to enter fastboot using the steps described in the post just before yours.
Edit: Of course you have to enable USB debugging in order to use ADB. I'm sure you knew that
