I had the avatar custom ROM on my phone.
wanted to sell it, so went into CModRecovery and tried to restore my phone to a previous restore point i had, thinking that would be with the Tmobile stock.
Anyways, right after that, my phone was soft bricked, constantly restarting. At the beginning i was able to go into recovery, and i tried to restore it to the previous point again, but it didnt work, tried clearing cashe and stuff, but still didnt work, and then I dont know what happened, but all i can access now is bootloader, cant even acced CModRecovery anymore.
I know my phone is soft bricked, and I've found the original RUU Tmobile for my HTC one S, and im using the Hasoon all in one toolkit to try and factory reset it, but the problem is, I dont have USB Debugging enabled, and my phone is soft bricked, so I dont know how to enable it now, and I cant follow any of these tutorials for fixing the soft brick, without it enabled.
So now my question is, how can I enable USB Debugging with my phone in the state that it is (ie, only thing that acccessible is bootloader)
Thanks for taking the time to read this, and I really appreciate any help.
I dont think you even need ADB at that point. From the bootloader you can enable fastboot (by selecting fastboot with volume keys and pressing power button to activate it). Then reflash the recovery from your PC by running fastboot flash recovery your-recovery-img.img Then you'd be able to access recovery again.
And when you restore a nandroid of another rom and are on a hboot version 1.09 or higher (and S-on) you also need to flash the boot part of the backup. So first you need to get the boot image to your PC from the phone. At least TWRP recovery has an option to mount storage as a USB drive, probably CWM has this also... Finally flash the boot image to your phone by booting the phone into bootloader, selecting fastboot mode as before, and then flashing the boot from your PC by running fastboot flash boot boot.img.
Hope this helps. I'm just writing what I would try in your situation .
Sent from my One S. Please hit thanks if I helped.
So this is what I did:
1. In bootloader, selected fastboot with the power button. Now im at the screen where it has 4 diff options: bootloader, reboot, reboot bootloader, and power down. Also on this screen, since I have the phone connected to the computer, it says FASTBOOT USB
2. So now I open up cmd and write what you said, fastboot flash recovery recovery.img (the cyanogen mod renamed to recovery)
3. And it says it failed.
4. So I cant proceed with the rest of what you said. I'm not sure why it failed, but does it have to do with the fact that my USB Debugging is maybe disabled, and thats why its not able to find the phone?
5. Because even when I was trying to get the Hasoon all in 1 toolkit to work, the reason I couldnt was because everytime I'd try something, it would say "device not found" in the cmd prompt window.
As I'm sure you can tell, I'm pretty confused :S

Did you relock the bootloader? Does it say *** RELOCKED *** or *** UNLOCKED *** in the top of the bootloader?
If it is *** RELOCKED *** then you need to unlock the bootloader again (here are nice guides for doing it. I don't remember the exact fastboot commands right now). If it says *** UNLOCKED *** then I'm unfortunately out of ideas. I did however do some googling and found this: http://www.askabouthugo.com/general...on-fastboot-with-remote-signature-verify-fail
And are you sure you are trying to flash an S4 version of the recovery and not an S3?

Ok! first download : http://www.4shared.com/zip/XG506hyV/icsroot-fastboot-recovey.html
just unpack, connect your device and click run.bat.....Good luck!
I ran the .bat, but I get an error saying "Device already rooted", but it is still not recognized as rooted by SuperUser.
Alternatively, is it possible to completely wipe the phone of everything (including root) so I can start over with a fresh phone?
Of course you can, and might be the best idea if you don't mind doing it.
Make sure you have the latest CWM recovery on your phone, download the FULL ROM from this thread (i'm not american so i don't know exactly, but from what i know yours is the I9020T, so get that ROM) and copy it to the SDCard. Now go into recovery, wipe system/data and dalvik cache, then flash the ROM.
Do make sure you have the right ROM though. This will get you 100% fresh and untouched 4.0.3. You can probably clear out any non-personal folders on the sdcard too, but that shouldn't do any harm anyway.
After this, use the attached file from this thread to root, and feel free to update root/superuser.
Actually, that's what I did...I can't use CWM recovery because its displaying an error of no root. So how do I wipe this or fix CWM?
Is your boot loader unlocked? And are you trying to flash cwm through fastboot?

My bootloader is apparently unlocked and I'm trying to flash through fastboot.
Are you sure the following is satisfied:
-open padlock and google logo on boot
-fastboot (on phone) says "bootloader status: unlocked" or something of the like
-you are using: "fastboot flash recovery "C:\path\to\recovery.img""
-you are using the above command while connected to the PC via USB (with working drivers) and that you are in fastboot mode on the phone (turn off phone --> hold Vol. Up then hold Power TOGETHER for about 2 seconds, should give you reboot and recovery options)
It is necessary to be in the bootloader/fastboot interface on the phone when you run the command. Hopefully it was something simple that i said above, otherwise i'm completely lost.
1. Yes
2. Yes
3. I didn't use that method to root...
4. I'll try that.
3 is just flashing recovery, that is the code u type into cmd/terminal to reflash the recovery img. It isn't rooting the phone. 4 is how to get into the mode on the phone to use the command.
Its a bit confusing at first but makes much more sense once you do it one or two times.
Where do I go to get the recovery image?
The latest ClockWorkMod Recovery can be found on this page. Just scroll down to Nexus S and download 5.0.2.0 crespo .img. Then just direct fastboot to the folder you have it saved in while using the "fastboot flash recovery C:\path\to\recovery.img" command.
Ok. I've tried this, but in command prompt, I get the following error:
C:\Users\Bruce>fastboot flash recovery C:\Users\Bruce\Downloads\recovery.img
'fastboot' is not recognized as an internal or external command,
operable program or batch file.
Check out this rooting guide, however only go up to step 5 (and do NOT type "fastboot oem unlock", do everything up until that point). This will setup fastboot for you, and setup drivers for your computer. Once this is done, do what you did above and it should work successfully.
Remember to cd (change directory) in cmd to where you unzipped that folder.
There isn't a link...
Sorry, stuffed that up. I fixed the link in my previous post pointing to NexusSHacks - How to Root Nexus S.
It's worked, but when I try to go to the recovery menu, the Google/unlocked padlock screen freezes or it displays an Android with its chest compartment open and a red triangular ! symbol.
I just had a really long reply and managed to lose it by closing the page..
That's the stock bootloader you see there, it probably didnt flash or you rebooted your phone. And make sure that you are flashing the latest CWM you downloaded before.
I flashed the latest CWM, but when I try to go to recovery, my phone freezes at the Google logo with the unlocked padlock.
Have you tried flashing it again, or maybe redownloading the file? And of course making sure it is the NEXUS S version which you are downloading.
Alternatively, try just "fastboot boot recovery.img", replacing recovery.img with the full name and path of cwm.
edit: btw, i'll be gone for an hour or two Bruce so i can answer any more questions/issues when i get back
Okay, first of all I know, I'm a total noob. I have followed these forums a long time and have successfully rooted a few phones. One of which was my nexus s 4g. I was trying to unroot the phone so I could get ics. This is when I ran into problems and right now I just want to be able to get my phone working again. Right now I am stuck on the Miui boot up screen and no matter how long I wait it stays on that screen. If I do a battery pull and hold down power and vol up I can get into the bootloader screen with the information as follows: fastboot mode, product name-Herring, HW Version Rev 34, Bootloader version-D720SPAKE1, Baseband version-D720SPAKE1, Carrier info, SPR, serial number-37308B81276A00EC, Lock State-locked. Then the different options I can choose are reboot bootloader, reboot, recovery, power off. If I choose reboot, it takes me back to the mius screen and stays there. If I choose recovery, I get the triangle with the exclamation point. I then hold power and up volume again and I get a screen that says Android system recovery <3e> with reboot system now, apply update from sd card wipe data/factory reset and wipe cache partition. I have tried all of these as well with no luck. When I go to apply update from sd card I get matrix-cfs_v15.5 zip, root.zip, update.zip and then what looks like apps such as Alarms/, Android/,MIUI?, etc. If I try to select any of the first ones such as matrix-cfs_v15.5 zip, I get Install /sdcard... , finding update package..., opening update package..., verifying update package..., E.signature verification failed, Installation aborted. Then it gives me the system recovery options again. Any help would be appreciated.
Did you try ADB fastboot method?
Not sure how to try that
I tried doing the adb, followed all directions and installed and when I go to the command prompt and type in anything, such as, adb reboot bootloader I get, adb is not recognized as an internal or external command, operable program or batch file.
ok I got that working now but when I type adb devices and press enter I get a message saying List of devices attached and then it doesn't show anything and I get the command prompt again saying:c:\android\android-sdk\platform-tools>
also since the phone is stuck in either the miui screen or bootloader I can't get into it to put it in usb debugging mode. I am trying on my own to get this going and am stuck any and all help would be very much appreciated.

I think that means you have a locked bootloader.
And from what you're telling, I believe you have stock recovery.
Also, when you're in fastboot mode, I don't think adb commands apply. Use fastboot commands instead (i.e. fastboot devices).
Search for guides showing you how to install and use fastboot.
I did fastboot as well and the problem I think I am having is it's not recognizing my phone because usb debugging wasn't turned on before it locked up. How would I get it to recognize my phone or download an img to my phone if it is not being recognized. Sorry if this is a stupid question.
You don't need usb debugging in fastboot mode.
You either:
1. Don't have drivers installed.
2. Don't have fastboot installed correctly.
You really need to read a guide or two, through and thoroughly.
Bc it sounds like you have no clues.
Yeah dude. Take a step back and go over what you have installed and where you installed it.Yes, fastboot commands start with fastboot instead of adb. And you're on stock recovery.
Thanks for the answer that I don't need usb debugging in fastboot mode, I wasn't sure of that. I have downloaded and installed my drivers multiple times and when I use the device manager to update drivers it says I have the latest drivers installed already. Whenever I do fastboot commands I will type in fastboot devices and shouldn't my device serial number come up? It just gives me the line c:\android\android-sdk\platform-tools>
And is waiting on me to type a command in. And yes I have been looking at guides all night. I appreciate any help you guys might have and remember we were all noobs at one time.
The zip in this tutorial should help.
It has adb, fastboot, and the drivers needed.
And unlock the bootloader because it is locked.
Finally got it, I had everything downloaded that I needed already, but looking at different forums, etc, it seemed like everyone named it something different. So I just used the one link you gave me and did it exactly the same way and it worked. Thanks so much! and again thanks for your patience.
Two days ago, I unlocked my bootloader and it wiped everything. After that, I installed TWR and rooted the device with a toolkit.
Now I don’t know what went wrong, but I would like to flash CWM recovery instead of TWR, but...
it’s now showing that my bootloader is LOCKED.
And I cannot unlock after I’ve tried using adb, cmd, or the toolkit.
I will hold Vol Up+power to enter fastboot and as soon as I hit “unlock bootloader” or enter “fastboot oem unlock” in command, the phone immediately starts into TWR.
Without an unlocked bootloader, I cannot flash anything via the bootloader.
Any help would be appreciated. Thank you!
Turn the phone completely off. Hold volume up + power, plug the phone in via USB (ensure that you have the drivers installed for the phone)
fastboot oem unlock
fastboot reboot
then go back into volume up + power (fastboot mode)..... fastboot flash recovery <recovery-name>.img while the recovery file is in the fastboot.exe folder. then boot into recovery.

You see, I cannot even get to the part where I reboot the phone myself because the phone automically does it for me and jumps itself into TWR recovery and does not unlock the bootloader for me.
It takes less than a second from when i run the command "fastboot oem unlock" to when the phone reboots. Then it take about 15 seconds to get to the TWR recovery.
The only drivers I've installed on my Win8 (tried Win 7 as well) are these:

I actually had that happen to me too. When I typed fastboot oem unlock, my phone just instantly rebooted. But the bootloader was still unlocked. Use http://forum.xda-developers.com/showthread.php?t=2788632 and start from scratch. Use Universal Naked Drivers 0.73, they work amazing. I had these drivers installed before so I didn't even need to install drivers.

Silly to ask, but you unchecked the cm update in dev settings and enabled debugging?
Personally, my second lappy didn't even list the device in fastboot, but the commands still worked.
I would just boot into fastboot and run the all the commands in series.

I've already tried this on 3 different computers.
I don't see how having dev mode would affect bootloader if I never boot into the OS.

Hi lemonspeakers,
sadly I don't have a solution, but the same problem.
Current state:
Bootloader locked
TWRP installed
no root
Sending "fastboot oem unlock" causes reboot to recovery.
Besides that the phone is fully working. (My friends thing I'm crazy because I'm sad about a fully working, "normal" phone
I hope somebody have suggestions to fix the issue.
Update:
I've just seen the tamering fix thread and I'm going to try that, too,
Did it work for you?

I flashed the script, than used this guide (again):
http://forum.xda-developers.com/showthread.php?t=2788632
Than it looked like the only improvement is, that the bootloader is now unlocked. Root didn't work.
I could fix that by going to Recovery, factory reset, reinstall SuperSU an reboot. My phone now is finally rooted.
I think the factory reset part is strange, but I'm so glad I now have a rooted OPO.
When you try it, please let me know if you also have to do a factory reset.

Hi there,
Im still kinda a noob with android...
but i managed to unlock my htc sensation trough the steps @HTC,
changed the recovery, tried to flash a rom.
it failed due to my phone not being S-off. so i flashed it back :/
no problem there i thought just a rooted htc.
downloaded an app to remove bloat. and all seemed fine...
I was playing Clash of Clans, and it gave a message that the Google play services stopped and the phone rebooted.
when booted the lock screen was frozen, i pulled out the battery to find out my phone is unresponsive..
When i connect to windows 8, it cant recognize my phone at all
When i connect it to a charger i dont see the charging light.
and the worse thing is.. i cant get into the recovery.
any idea's what i can try?
i checked out the [unbrick] tread but i cant seem to figure out which "Package" i need and the links on the bottom of the page dont work when i click them
Thanks in advance
-Aline
At first you have not to be S-OFF in order to flash a rom.
Your rom will get installed just fine.You just need to flash the kernel of your rom manually through fastboot using the command fastboot flash boot boot.img.
What exactly do you mean by telling "so i flashed it back"?
Did you relocked your bootloader with fastboot oem lock and you flashed an RUU?
You said you are just rooted.If my theory was right you probably unlocked your bootloader again by flashing the unlock.bin and a cwm recovery and then you had to use a (Superuser , SuperSU zip).
The first time you unlocked your device was you using the same computer with windows 8?
If yes this is a problem.Check your device manager for unrecognised devices.Can you see the device?
Check this out.You can also check this.
(You can try with win7 or a linux destribution instead.)
Are you still able to boot into bootloader (hboot) using (Power)+(Vol-) Buttons?
If you have enabled usb-debugging and a working adb shell despite you are in a bootloop you can try:
Code:
adb shell
su ------>(If you don't see # instead of $)
reboot oem-78 -------> To get in RUU mode
or
reboot bootloader -------->(To reboot into hboot)
* reboot recovery could bring you to recovery *
If you can get into hboot or RUU mode give the command fastboot getvar all and copy-paste what it prints.
I know it was possible to flash with S-on,
thats what i tried and it failed (manually flashed the boot.img resulted in a bootloop)
so i flashed back to the "stock" rom.
resulting in a "normal" rooted device
since i've replaced my recovery and got root access
it never has been oem locked again.(still isnt)
i cant get into my bootloader/ruu mode. nor start up.
when i plug it into my computer (windows 8) it makes the sound as it does when you connect a device.
but in device manager it shows nothing, not even a yellow ! as it normally would if it can recognize a device.

As you have not access to bootloader but your device is still seems to get connected i think you can only try HTC Unbricking Project.If the brickdetect.sh is not working you can try a different linux destribution.

Purchased an Lg Gpad 7 Wifi tablet (v400) 2 weeks ago. Came with preinstalled Lollipop android so i couldnt install a recovery rom to flash any other custom roms. Downgraded to Kitkat version following the instructions on Xda forums and succesfully installed Twrp. When i installed Cyanogenmod 12.1 through Twrp i got stuck in fastboot screen.
Any suggestions and / or solutions would be greatly appreciated.
I had a similar problem.. Only mine was stuck at the bootloader. Go in TWRP and repair /data and other partitions. My data partition gave me an error since F2FS is a little flaky and some ROMs corrupted it (claimed they supported it). I would recommend erasing the system, cache and data partition if you can't get into TWRP.
The problem is i cant get out of fastboot whatever i try. It says start on bootloader but the tablet just restarts on an empty screen doing nothing.

if you have an sd card, try removing that, then reboot.
if that doesnt work, try entering fastboot command, fastboot continue
Tried without sdcard and i get the same fastboot screen.
How can i give any commands? The only options i have are Restart Bootloader / Restart / Power off. Tried restarting bootloader but i get nothing in return tablet just stays on with nothing on screen.

you said it was stuck on fastboot, if thats the case, install any needed drivers on your pc, connect device to it, open a terminal in the fastboot dir (after you go get fastboot), then try those commands i gave. you could also try, fastboot reboot dont think i mentioned that before.

hmm, ok, im guessing it would have said that normally, when not broken. all the command does is try to release it past where its stuck. it doesnt actually flash, lock, unlock, or change anything.
imo, this seems good, because now we know fastboot is working.
i own lg devices, but not your specific device. i would hate to give you some bad advice and make your tablet broken more, but if it were me in this situation, i would try to flash the factory KK firmware you used to downgrade with odin or however you did it. hopefully, that will clean everything up and let it boot properly.
if for whatever reason you cant do that, we could try extracting the factory file, and just flashing recovery and system, those should be the only things that got changed putting on twrp and cm normally.
Sorry, I have the serious proplem wtih my LG pad V400, I rooted it and using <LG Flash Tool 2014> with <V40010c_00.kdz> to downgrate the firmware but their is error then my LG pad stuck in fastboot menu as with just turn off, restart and restart bootloader. if i seclect one one them the tablet just logged again the fastboot menu
it stuck on the fastboot menu and i cannot do nay think with it. I can restart with factory restore mode but when select yes to restore, it will restart and log in fastboot menu again.
I downloaded adb and fastboot program and put in one folder <Minimal ADB and Fastboot> in C:\Program Files (x86)\Minimal ADB and Fastboot
