Solution to RUU: Code 152 !!!

Hey everyone,
so i tried to run a RUU for GingerBread on my incredible s and forgot to do "fastboot oem lock"
i ran the ruu and it told me error code 155 and i facepalmed myself -.-
and now i seem to be inable to access recovery NOR bootloader...
i cant even start my Phone up
the only thing it shows is a black screen with hTC on it and in the 4 corners a white triangle with "!" in it...
Can someone help me with reverting back to STOCK GB rom without root etc. s-on etc.
because i want to sell this Phone (no i dont :/) to buy a hTC One X+ and i need the stock stuff for that
NOTE: i *had* BlackRose s-off
Another note: computer recognises my Phone in fastboot mode so i can use fastboot commands but not adb
EDIT: now i get code 152 image update error...

Run Blackrose Tool and there is an option for uninstalling Blackrose HBOOT. That will give you Stock HBOOT 1.13.0000 and then run latest RUU.

So how do fastboot commands work? You have to be in bootloader to access fastboot....
Are you pressing volume down and power?

Yeah i know is kinda weird how i get to fastboot, idk neither
i just press power button and my pc recognises my Phone in fastboot state
and i am able to use *almost* all fastboot commands such as fastboot flash blahblah and fastboot reboot-bootloader and blahblah
if i start up, again, i still get a black screen with silver HTC letters on it

Can you please say what it says in your bootloader now?
In all honesty, if you can't access the bootloader, you're pretty much f**ked :/
Your last hope is recovery and trying blackrose tool there

Well, that was definately a way to put it xD
But yes. If you can't access bootloader, you may have problems.

oh well, F*** then cuz i cant Access bootloader properly to choose recovery from it
i m going to try few more things,
1. do it via sdcard and fllash it
2. remove radio.img from the OTA and flash it since it gives an error
i can Access bootloader but when i do that, my bootloader shows me
***BlackRose***
some information...
and then it shows in orange "RUU"
i cant Access anthing from it and when i plug charger back in it goes into RUU mode
i know what my problem is, but i cant find any solutions, "fastboot oem lock" is an unrecognised command... does it have to do with something about htcdev.com?

(DESPERATE NOOB) Soft-bricked?

I followed all the instructions for rooting my device but there must have been something I missed. Here is what I did:
Developer Options - USB Debugging and OEM Unlock enabled
Downloaded and installed android-sdk-windows as specified in this tutorial
Followed all steps to reach "fastboot oem unlock" in the cmd prompt
Once that is entered, it prompts me to unlock bootloader on the phone. When I try to proceed with the unlock, the cmd prompt replies with the following:
(bootloader) Device state transition will erase userdata.
(bootloader) Are you sure you want to continue this transition?
(bootloader)
(bootloader) Press POWER key to continue.
(bootloader) Press VOL UP or VOL DOWN key to cancel state transition.
(bootloader) State transition confirmed!
(bootloader) Please select 'YES' on screen if you want to continue...
(bootloader) Unlocking bootloader...
(bootloader) Not supported command in current status!
FAILED (remote failure)
finished. total time: 17.525s​
When I try to reboot the device, it displays "your device is corrupt. It can't be trusted." at which point it either turns off on its own or immediately after touching a button.
Please let me know what other information you need to help. Thank you!!

That's because you unlocked the m-bootloader. Your device is normal, but Google doesn't want us to unlock/root. Ignore it and flash a rom. Start here http://forum.xda-developers.com/showthread.php?t=3059493

Question about

Hi everybody, I have a little question regarding my P10.
The model of my phone is VTR-L09C521B101
Is there a way to flash this phone with VTR-L09C432 version?
or i need to flash with same model version (VTR-L09C521)?
Thnks

Yes, it is possible to 'rebrand'. The procedure is explained in the Mate 9 forum. It is not so easy and involves unlocking the bootloader.
Updating can be done with the Firmware Finder (Playstore).

thanks for the answer!!
regarding bootloader, the phone shows this:
PHONE RELOCKED
FRP LOCK
ADB shows me that the phone is unlocked, the problem is when I try to send something to phone it shows:
Error Remote command not allowed.
any ideas?
thanks!

I've tried to reword the mate 9 instructions for the p10 here: https://forum.xda-developers.com/p10/help/rebrand-firmware-finder-t3685951
As for adb, what command are you trying? Do you see your phone if you type ADB Devices?

Since I uploaded boot img of another version (C432) full OTA, could this be the problem? in this case what can I do?
thanks for your help!!

Could this be happening because of FRP Lock?, none of the software I have tried (DC-phoenix, chimera and Unlocker v2) worked. Im this close to throw this f*ckin phone to trash u.u

edit: just found this in another thread "FRP Lock occurs when the phone has a firmware mismatch and or oem unlocking is not on in developer options"
Hmm, i've just checked my phone and in fastboot it says PHONE Locked, and FRP Unlock. I think that may be your issue. What exactly did you do to flash your phone with the other version? put an UPDATE.APP into a \Dload folder and 3 button update?
is your phone booting (guessing not). my guess is that you need to get a hold of your stock firmware file an flash that first.

Ok, this is what I've done step by step:
1.- With the unlock code provided by huawei, I have unlocked my phone (my version is VTR-L09C521B101 stock)
2.- Once unlocked, I have downloaded another ROM version (VTR-L29C605B151) in the web page says this rom is for latin america), so with the Huawei Update Extractor, I have extracted all files.
3.- Via ADB/FASTBOOT, I sent the files to my phone, boot.img first and then the others. (big big mistake!)
4.- Rebooted the phone, and then keeps restarting at huawei logo.
5.- Seeing that it did´t worked, what I did was to lock the phone again thinking to send it to Huawei (at this point the phone shows as "unlocked" via fastboot commands, however when I start the phone in fastboot mode, in the screen shows "PHONE RELOCKED, FRP LOCK"
6.- Sent to huawei's service, they said that they cannot fix my phone because it was tampered/rooted.
7.- Right now all I need to fix my phone is to LOCK/UNLOCK again in order to rebrand it to L29 version, since the original stock rom dont exist (not as FULL OTA).
And that´s what I did so far my friend.
Questions:
1.- Is there a way to connect to my phone and change the oem info file? or something?
2.- Do I need to wait the stock rom to be released in order to reflash via Dload method?
3.- What if the stock ROM version of my phone is never released?
thank you for your answer my friend!!

Hmm ok. I am just not sure on your step 3, I've never heard of a method that involves a boot.img... what I would suggest, is to try and download the stock firmware files (need the larger full ota files), extract the update.app file and put on sd card in \dload.
Then hold down both volume up and down and power (3 button method)
It will try and flash the stock image back to the phone.

I just tried the Dload method and nothing happened (always stuck in 5%), now im going to try to use a smaller memory card (mine is 64 Gb). lood

Hi,
For Working this command "Fastboot oem get_unlock_data"
First you need to remove or delete your phone's SCREEN LOCKS like your fingerprint, face-unlock, pattern or password etc... And keep on NONE option in lock screen. After all above procedure done than, You run that commend "Fastboot oem get_unlock_data". After runing thant command, You will not get "FAILED (remote: unknown command)"
It will work 200%.

It depends on your fastboot version. Please check "fastboot --version" and post it here.

same

Did you try another USB port? Some users reported that USB 3.0 did not work but 2.0.

I would be willing to bet this is happening on devices that are not allowed to be unlocked. Like those purchased from a phone company.

its been a week since i'm trying on my htc 10, but getting the same error, i tried,
- delete the drivers and re-install
- delete sync manager
- enabled debug & oem unlock
- done reset factory for the phone
- change USB ports and cables
- tried 3 latops
nothing works, sometimes i'll just the error "waiting for any phone" and other times "FAILED (remote: unknown command)"

I'm following a tutorial and obviously got stuck and the very same step as you did. And presumably you are following a tutorial, too.
1. Go to Security Settings and remove device lock (PIN, fingerprint, whatever you are using) and set it to NONE.
2. Go to Developer Settings and Unlock Bootloader. (If you skip step 1., you'll be asked to unlock your device here, but find that the Unlocking failed afterwards. Hence, go to step 1. and remove the lock first.)
3. fastboot oem unlock
Done. (Bootloader is unlocked now. Confirm via boot to fastboot mode (Volume down + Power button))
fastboot oem get_unlock_data is probably removed (deprecated) and maybe you don't even need a key from the manufacturer to unlock anymore.

You still need a key to unlock the bootloader for the first time! When it's locked with status "flashing_locked" you don't need a key for it.
Is it a brand new device...?

If that question refers to my post: I have a Moto E4 (XT1762). Bought it like half a year ago to tinker around with. I started it, ran all updates available and set a device lock (here: PIN).
Today I finally found the time to get started with lineageos and followed the guide at: rootmygalaxy.net (download-and-install-lineage-os-16-on-motorola-moto-e4-android-9-0-pie)
I got stuck at the error the OP had. (This lead me here.)
In my case I got past the error by doing the steps mentioned in my first post, i.e.
1. started the device (normal boot) and got rid of the device lock (PIN in my case), enabled USB debugging, enabled bootloader unlocking
2. powered off the device and started it again in fast boot mode (volume down + power button)
3. On computer / in terminal: fastboot oem unlock (without any key from the manufacturer)
The device showed a confirmation dialog. (Volume up: Yes, Volume down: No)
Code:
[email protected]:~/downloads/lineageos/Android_SDK_platform_tools/platform-tools$ ./fastboot oem unlock
(bootloader) Start unlock flow
OKAY [ 9.657s]
Finished. Total time: 9.667s
Now in fast boot screen I see Device Status: unlocked
I just wanted to share my experiences from today's struggles and maybe it'll help the OP.

Moto E4 is a developer's device without a locked bootloader. I thought you were talking about a Moto G6.

I have tried to flashed a rom with miflash tool. I've checked clean all only. And it showed "error FAILED (remote : Erase is not allowed in Lock State)".

It means bootloader was already Locked.
On which rom were you before?

Unfortunately you have to flash a rom using EDL mode with an authorized account, hard brick is a very awful thing.

Thats why you need to read before doing anything with your phone. Almost every thread has flashing guides and all say that you have to unlock bootloader first to flash with miflash or to flash with twrp to avoid hardbricks. Edl is the way to go, good luck mate
