Hello community!!
I'm new to the HTC/Incredible S world, I have a rooted/cfw LG P500 and now I bought this great phone. Problem is that I updated it to the last official version before this try.
So I went to the official site and I followed successfully the HTC site steps to unlock the bootloader (golden card?) and now I'm trying to follow the guide
http://forum.xda-developers.com/showthread.php?t=1385084
But I have some problems.
First of all clearly the revolutionary program doesn't work (HBOOT 2.0).
I booted to the bootloader (power+volume down) and I had the error "main version is older" then I copied on the SD card the file for the recovery PG32IMG_Vivo_Gingerbread_S_KT_KR_2.32.1010.1_Radio_20.2810.30.085AU_3805.06.03.16_M_release_199684_signed.zip, I renamed it PG32IMG.zip, it loads it but when I press recovery it gives me an allert icon (the phone with a red triangle + red "!" ) and it does nothing.
I installed the SuperUser app like it is written in the post but when I type SU under the adb shell and it gives me "permission denied".
What could I do?
Is it even possible to downgrade it to a rootable/customable version?
If someone write a guide for rooting with the last update installed from original s-on step to step will be very util and a lot of people will be gratefull!

Bootloader unlock and goldcard are 2 seperate things. Bootloader unlock is required at the moment for flashing recovery and superuser for rooting the phone.
Gold card is required for flashing another carriers rom.
Read this thread about recovery http://forum.xda-developers.com/showthread.php?t=1104765
After that you can enter recovery mode and flash a superuser zip file http://goo-inside.me/superuser/
My guide should be able to downgrade your rom and get s-off after that (if after researching you decide you require it) http://forum.xda-developers.com/showthread.php?t=1373697
Hope this helps
Thanks, I'm going to try this as soon as I can, I'll write back the results
edit:
It seems like I can't even pass the first step, the 4EXT Recovery Updater doesn't work, it crushes at EVERY menu item....
(I waited 5+minutes and I had the internet connection on).
I checked and the boot loader says "unlocked". Notice that my device is, of course, NOT rooted (at least for what I know for "rooted", it is still unlocked by the HTC official method)....
you need root to use the recovery updater.
download the recovery image and flash it in fastboot
Thanks it is finally working!!
I totally forgot that you flash with fastboot via windows console, not within the bootloader....
I hope to finally install something tonight, I'll post some news later.
Thanks again!
edit:
Nothing..I went successfully to the RUU downgrade part but that doesn't work, I tried from the normal system and it blocked because of the hboot version, then I tried within the phone fastboot phase and it blocked again, giving the security failed error...

Hi!
I have successfully rooted my phone on the last update 2.3.5
The steps I made:
1. Going to htcdev and unlocked the bootloader
2. Flashed a recovery image from clockworkmod.com
3. Installed SuperUser from clockworkmod.com using recovery
I collected the information from a few threads here and had no problem.
I didn't tested custom roms, all I wanted was to root and worked just fine.
I can detail my steps if someone need it.
edit:
It seems I cannot post the images, too noob ....
Anyway:
I had a photo of the phone in the custom recovery mode, another of the phone with the 4EXT recovery successfully flashing his recovery, another of the script of your post running with this message:
(no errors)
Do you have an unlocked bootloader from htcdev.com (I have)
y OR n:y
<waiting for device>
...
(bootloader) Lock successfully..
FAILED (status read failed (Too many links))
finished. total time: 0.239s
Note: run the RUU in fastboot mode
If all steps etc etc
Now if I try to run RUU NOT in fastboot mode I receive the message:
The Utility of ROM udating can't update the Android device.
Take a valid ROM updating Utility and try again
(I'm translating from Italian)
If I try to go to fastboot after running the script I need to go to hboot using volume down+power since you can go to fastboot only through bootloader and HIS first step is to check the bootloader file (am I right?)
so, since it is again LOCKED the custom boot file I was using PG32IMG_Vivo_Gingerbread_S_KT_KR_2.32.1010.1_Radio_20.2810.30.085AU_3805.06.03.16_M_release_199684_signed
doesn't work anymore and the old one neither so I have to unlock it again and it goes the loop......
So this is the situation, I hope I will be able to post some image soon...

Thanks, I did too the 3 steps, rooting my device successfully...
But I think I need to do a total S-OFF (deeper than the HTC one) to use the CFWs.
It should be like: follow the above 3 steps and:
4. use some script/console command to prepair the device
5. DOWNGRADE it to 2.2 or something
6. use the "revolutionary" Utility to S-OFF permanently
7. flash the ROMS from the recovery
I cannot pass the 4th step.

OK, I thought you only wanted to root.
Thank you anyway
You don't need s-off for CFW's, just the unlocked bootloader. I cannot help you any further until I see screenshots as I'm getting lost in your descriptions. Ctrl prtscrn, paste in paint.
Well, I have the screenshots but I can't post web links in the forum (new user).
Let's see if I can flash some cfw in the mean time
Now I can post

After you flash a custom ROM in recovery, you have one last step to do to prevent the hang. You extract the boot.img file from the ROM's zip file and then manually flash it in FASTBOOT mode on the phone:
FASTBOOT flash boot [path to boot.img]
That totally solved the problem
Thank you ALL!!!

Hi,
Please list the methods you use from the start. I have also 2.3.5 and hboot 2.0. cant manage to downgrade, i always getting an error.
Thanks
htc developer site -> unlock bootloader
find and download this file:
PG32IMG_Vivo_Gingerbread_S_KT_KR_2.32.1010.1_Radio _20.2810.30.085AU_3805.06.03.16_M_release_199684_s igned.zip
copy it on the sd card and renamto to pg32IMG.zip
reboot in power+volume down mode
go in fastboot
from your pc use fastboot to flash this recovery:
http://forum.xda-developers.com/showthread.php?t=1104765
copy to sd card the superuser file:
http://goo-inside.me/superuser/
enter recovery mode and flash the zip
Then if u want to flash a custom rom you dont need to downgrade, just copy the zip into the sd card, flash it, copy on the sd card the boot.img you find inside the rom zip file and reboot in fastboot (power+volume down)
FASTBOOT flash boot [path to boot.img]
and reboot and the job is done!

Can someone be gentle with me and explain how to plug the device in fastboot mode and flash the kernel.... I work with the Xperia devices and there the life is easier xD. So the questions are:
1)Where can i find the drivers USB?
2)How to plug the device in fastboot mode??
3)How to unlock bootloader
and i think that when i achived those passages i know how to go on... maybe like this:
1- Enter in the folder with fastboot's files inside
2- press shift + right-click and then select open command prompt here
3- Type: fastboot flash boot boot.img

The Optimus Black doesn't use fastboot. Everything is done through recovery.
Download Clockwork Mod from the Play store, use that app to flash a custom recovery.
Enter recovery by repeatedly pressing volume down at power up or use a reboot to recovery app.
To flash roms/kernels, copy to your sd card, boot into recovery, select install zip.
The bootloader is not locked, unless you have flashed the offical LG ICS rom with the smartflash tool. If you have and want to unlock it, just flash any froyo/gingerbread offical LG rom with smartflash, that will unlock.
1. Make sure you are rooted, if not, read Nooby's how-to on how to do it. It's a sticky in LGP970 section on xda.
2. Once rooted, you can install ROM Manager and flash cwm/twrp recovery from there. Give it root permissions when asked for.
3. Boot into recovery using ROM Manager or any other third-party app. Flash the .zip for the kernel you want. Make sure it is compatible with the ROM you are using.
4. Once kernel flashed, boot into the system.
Bootloader is generally unlocked unless you are running official ICS on your OB. If that is the case, don't do any of the above mentioned steps as you will end in a boot loop.
If on official ICS, use Smart Flash Tool to flash unlocked bootloader. You can follow instructions here on jockjoint's thread
Once bootloader is unlocked and you have flashed su.zip as per instructions in the previouslsy mentioned thread, boot into recovery (it's already there in the unlocked bootloader flash).
Once in there, flash a compatible kernel and ROM as per your needs/liking.
Hey everyone,
so I have an issue, I hate taking care of other peoples devices, but my dad asked me to root his Optimus 4x for him, so I did.. or at least I gave it a try.
I unlocked the bootloader, rooted it and tried to instal a custom recovery, with no success.
the OS the device had is 4.1.2 JB, and I tried to flash the ICS recovery, which caused a permanent bootloop.
luckily (I guess?) I can access the recovery (which is STOCK for some odd reason) but the device never boots back up when I restart it. I tried to wipe everything that the stock recovery allows me to, no success either. I tried to use the LG tool, I put the IMEI and hoped for the best - nope, it didnt help either. it kept on saying the device has disconnected.
SO I figured the way to go would be an adb flash of the right recovery and then flashing a custom ROM, but I cant push the recovery image to the sdcard, it says there's no such directory. this is the command I used:
adb push recovery.img /sdcard/recovery.img
I tried various combinations and at this point I'm kinda lost and confused. Perhaps some more-experienced people could give me a hand? I've spent 6 hours figuring this out
EDIT:
the only way of turning the device off is pulling the battery, I can use adb, and I tried to flash the wrong recovery accidently.
thanks

try to flash stock rom using KDZ method (http://forum.xda-developers.com/showthread.php?t=2069723), that lets your device like new, and then try to start again, I recommend you to use lg p880 toolkit look into download section (http://forum.xda-developers.com/showthread.php?t=2230934), and you can download CWM 6.0.4.5 and replace the recovery in files folder of p880 toolkit and get the latest recovery that allows you to instal the most recent ROM
Le'mme guess, you didn't even think about unlocking bootloader, amaright?

No. As stated in the first post, I did in fact unlock the bootloader. I also confirmed it in the secret menu and it said "Unlock" which as I presume means the bootloader is unlocked.

I'm sorry i missed the first line, what got me was when you said you flashed recovery but it was still the same
The adb command to flash recovery is
1) adb reboot oem-unlock
2) fastboot flash recovery /path/toyour/recovery.img (not adb because you must use fastboot when in bootloader)

hey, thanks for your reply.
I assume the /path/toyour/recovery.img is a path on the phone, the thing is I cant copy it to the internal storage with adb for some odd, unknown reason (well the reason is the directory doesnt exist). I'll try to return to stock first, and I'll post the result.
thank you again
EDIT:
SOOO I managed to fix it and get it all to work the device boots up normally again thank you VERY much for all your kind help. I love you guys!!

Do you have a custom recovery already installed? Which one? If you don't, remember that in order to flash a new ROM, you need to install a custom recovery.

Sure, buddy.
You need to download a custom recovery, this is the option in Android that lets you erase all content in the device and do other things. With a custom recovery you can do even more things, like install .zip archives or ROMs, erase partitions, dalvik cache, etc, etc, a lot of things.
I personally use this one: http://forum.xda-developers.com/showthread.php?t=2552622
Since you are already rooted, I think that you are familiar with fastboot. In order to flash a custom recovery, you need to do this:
1. Download the custom recovery
2. If it's in a .zip, extract the archive so you have one *.img archive.
3. Then, copy that file to the folder where you have the fastboot.exe archive.
4. Open Windows command console and change the directory to the one where you have the files.
5. Turn off your device, then press volume down key and power key. Hold until you see a black screen with white letters. Connect via USB to your computer.
6. Run the following command in the command console of Windows:
fastboot flash recovery recovery.img
Where "recovery.img" is the name of your custom recovery archive, for example, "philz_touch_6.22.7.img"
7. Wait about 6 seconds and in the console you should see something like "done", I don't remember exactly what does it says.
8. You are good to go. Turn off your device. Then press the volume up key and power button. Hold until you see the custom recovery interface.
After this point, you can flash the custom ROM of your preference.
In the Philz link above, it goes to our thread that links to the main one, from there, download the unified moto-msm8960 one labeled for xt925/xt926. Last time I checked it was more up to date than the native mb886 one (not surprising since our CM repo is gone).

First of all, Xposed is a great danger for unexperienced users. Do not do some "cool things" to your phone without having a backup of your entire system available.
Hopefully you are able to boot into recovery again and restore your backup. If you do not have a backup, do a factory reset (you will lose all your data, but without a backup available...)
If you are on KitKat, install Xposed directly from here.
You can flash a custom recovery for your device by using an app called Flashify.
So my advice for you: try booting into recovery (if you do not know how: search for "your device name" + "recovery volume key". There should be a key combo available to boot into recovery. If this is not possible, make yourself familiar with flashing a kdz file...

Thank you, but my problem is into recovery, when I press and hold power button and +, my device shows me to enter a command with fastboot but when I try to enter in adb mode on windows with cmd my devices doesn't show, with command fastboot my device shows but i can't manage to flash a recovery image for my tablet (the second image), I'm trying to connect with my device trough adb or fastboot on windows, this is my problem. I can't enter to android, remember I've a bootloop and install flashify is not possible.
Finally I found the solution,
Solved. Bootloop on chuwi vi10 after install xposed. No adb or fastboot.
If you can't enter adb or fastboot (remote: unknown command)
You must boot Windows(hold power button and - volume) choose windows with volume buttons and later power button to select.
Boot windows and install ext2fsd http://sourceforge.net/projects/ext2.../Ext2fsd/0.62/
Start the program and you'll see all the partitions. Choose android partition 7gb more or less and ext4 type.
Assign a letter and select the option to mount on the next restart.
Restart windows, now you can enter into the partition on my computer.
Search files called xposed and delete them.
Icon change OS and accept. Boot android normally.

lol, okay, spoke too soon. not sure what I did differntly, but I tried it a few more times and it worked. Maybe plug in tablet only after you install the apk? meh. working now, I have xposed.
Enter e fastboot mode through the normar recovery and use ADB to unlock the boot loader, it should work
