corrupt bootloader s-off

hi
i just downgraded my desire hd and then did a radio s-off but then i wanted to do a S-OFF.
i used the easyS-off but then it said bootloader corrupt do not reboot.
i already tried without "I Have Radio S-OFF" then it just says connection problem
i have charged only and debugging turned on
what now?
thnx

hmm what about Easy Radio Tools?

i used that for radio s-off

it worked now!! thnx to this guy

second post!!

I would be hesitamt to reboot though, haven't used the easytool as I personally prefer to know what steps are being carried out, but if it warns that the bootloader is corrupt I wouldn't reboot until I knew the situation is corrected.

Hello guys (I suppose most of the visitors are in fact guys ),
I downgraded my DHD to 1.32 this week and managed to get root-access and did a successful Radio S-OFF using the One click Radio S-OFF.
However; this morning I tried the One click ENG S-OFF but the first time I tried to run the tool I got an error stating "Connection error (SD)". Rebooted my phone and tried again.
This time I got the error "Bootloader corrupt, contact XDA".
After I almost crapped myself I started to search for a solution; someone on this forum stated to go to application settings - superuser - and clear data. Did it and then I got a bunch of applications which did a forced close.
Tried the One click tool again and got the same error (Bootloader corrupt).
In the meanwhile I got all this popups regarding android.process.acore needed to close which finally resulted in an unusable phone so I rebooted...
Thank god this went alright and my phone is up and running again but...
I think the last failure was probably caused by the One click app that doesn't have root access (didn' t get a popup though), but I'm a little afraid to try it again.
Does anyone know if it's save to try it again?

Why not do it longhand? Concise instructions are available here, I realise you already have root but even if you follow the instructions from the begining they aren't gonna do any harm.

Thanks, that could be a solution however I found out that I didn't check the box "I have Radio S-OFF
Tried again with the checkbox checked but got the same error again.
The files that were copied to my SD-card at the first attempt are still there.
Is it safe to remove these files?
Maybe that solves it...

It is very important, that you agree the super user request while the tool does its job.
I had the same problems some weeks ago (bootloader corrupt), because during the flash my display timeout was reached and the super user request failed (black locked screen).
If the tool can not get root, it can not copy the bootloader. The message "bootloader is corrupt" is confusing, because nothing has happend.

Which is one reason I favour doing it long hand at least then youd know it's failed to flash the bootloader

Hmm, strange.
When I boot into the bootmenu (vol. down + power) it states the I'm already ENG s-OFF and hav CID 111111...
Something must have gone right....
However I can't find the line anymore that states that I have Radio S-OFF, is this normal behaviour?

Exactly! The instructions don't mention it, but when you run the easy s-off exe, it goes through a few steps and then your phone will ask you to allow superuser access. So have your screen on and be ready, and THEN run the easy s-off utility. That's all it was for me. I hit "OK" on the error message, tried it again but this time watched my phone and allowed SU access, and it worked fine.

Hi,
I'm posting here because i had the same problem ( Bootloader corrupt etc ... ).
First I rooted my DHD, and made it Eng s-off and installed a rom a few month ago.
Today I wanted to install another rom, and flash the radio.
But I did not remenbered if I already had the radio s-off, so i installed the 1.32 stokified rom, used the easy radio tool ( v2.2 ) and when i wanted to use the easy s-off tool ( v05 ), the program gave me the error message concerning the bootloader corrupt and stuff. I tried it with "I have radio s-off" ticked, and when I try it with unticked, I have a connection error message.
I tried to delete the data from SU, but it didn't help, and then I noticied ( remenbered ) that SU did not asked me the authorizations when I used easy radio tool ans easy s-off.
Anyone have an idea how I can fix that ? Maybe unistall/reinstall SU ?

HTC Desire HD radio S-OFF steps
http://www.youtube.com/watch?v=dTFphGbgqbQ&feature=player_embedded

Yes I did that after reinstalling the 1.32 rom, excepted the Visionary steps.
The root is permanent no ? I did it on my previous rom, so I don't have to root it again when I install another rom ?
Anyway, my DHD rebooted when I tried to secure the battery compartment, the bootloader wasn't corrupted, it's fine.
So I checked the bootload, I have ENG s-off and Cid 1111... this mean that my device is radio s-off too right ?

Yes, you can install custom roms and flash radios now.

[solved] hboot 0.75 --> GB RUU --> bootloop @ rom | stick it in the freezer!

hi
on friday I got a desire which belonged to a friend of mine and now through me becomes the phone of another friend. the phone was already rooted (I was the one who did it initially too) but that was a long time ago and there was no custom recovery (I think we used some kind of tethered-recovery) or anything like that on the phone. so I decided to correct that. my target was custom recovery, root, new rom, s-off preferably data++
unrevoked and revolutionary did of course not work for me so I decided to just flash the GB RUU basically like described here: http://forum.xda-developers.com/showthread.php?t=1626405
and that worked pretty good but now the phone is stuck in a bootloop which resets the phone right after starting the rom. I already tried reflashing the ruu (via goldcard just to be safe, though I am pretty sure I have the correct one (tmobile DE branded, t-mob101), that however did not change anything.
so now I don't really know what to do, please help me
thanks in advance

what's the hboot info?

thaaanks a lot. in the german forum so far noone has been repyling at all since yesterday.
fastboot and recovery (though stock) works btw.
fastboot / hboot info:
Bravo PVT1 Ship s-on
hboot-1.02.0001
Microp-031d
touch panel-synth101
radio-5.17.05.23
Jul 22 2011, 16:19:16

yeah recovery isn't gonna help..
Think you can only try the 2.3 RUU again.. otherwise you can't do much more.
------
If that doesn't work (after a couple of tries).. then the process is to:
- find an XTC Clip (they're expensive, not worth buying, look into whether some phone repair shops have them)
- S-OFF the phone with the xtc clip
- Download an alpharev stock bootloader pb99img (rename it to pb99img), put it on your sd-card and update it from hboot
- Do a full wipe in fastboot
- flash recovery
- flash a rom

then I have a serious problem. apart from trying over and over again I have no choice? because I as mentioned I already tried it twice.
could the radio be a problem because the point where the phone reboots should be the moment when it normally asks for the sim pin?
can you please point me to the absolut right RUU file? I just want to be cautious.
starting the ruu installer, getting the rom.zip file (which seems to contain nothing if I open it on the computer?), renaming it to PB99IMG.zip putting it onto the goldcard and starting into fastboot is the right way?

Ohh so it boots? If it does, boot it without inserting the sim, enable USB debugging, run revolutionary to S-OFF, flash recovery, backup the ROM, do a full wipe and flash a custom ROM.. see what happens then.

sorry if it was that easy I would have done that a long time ago ^^°
the phone also reboots if there is no sim inserted.
can I maybe flash some other RUU? another GB version, WWE instead of tmob UK/DE or even Froyo?) even newer stuff? I read something about a 1.03 hboot somewhere? as long as I get this running again I am pretty much willing to do anything. however I still wonder why this is happening.
I am dieing a little bit here, I'm so stupid
is it possible that I really messed up badly here:

Please note that the following regional variants are not compatible with this upgrade: Germany (Telekom Deutschland), North America, South Korea and Japan."
so still.. why is exactly is not working and how can I fix it...

no there is only 1 GB RUU.. try installing it from the .exe (boot into fastboot, plug it in, run RUU.exe).. see what happens then

i didnt know you could install RUUs from fastboot.
update worked perfectly like before but still reboots after 1 second in the rom.

Does the phone get really hot by any chance?

öhm how exactly should I test that? keep it runing in fastboot or repeat the bootcycle?

Umm nah, just when it boots, is it really hot? i.e. hotter than you would expect it to be...
Try sticking it in the freezer for 15 minutes in a plastic bag, then try turning it on again..

what the f? oookay one quick question before however: if I can flash the ruu from fastboot can I use revolutionary from fastboot too? (cause if revolutionary works all problems are solved, I did not dare to try that since the new hboot came with the weird gb update)
I would not say it gets any hotter than usual however freezer it is

no, can only use revolutionary when booted into the ROM unfortunately
If you got hold of an XTC clip as mentioned before however...
The freezer thing? some Deisre's have faced hardware faults before causing them to overheat, reboot all the time etc. if you tried to use a RUU it would always fail.. sticking it in the freezer helped.. for a few minutes.. so trying to see whether this is the problem.

you sir are my hero of the day
it booted! awesome, incredible, how could you even think of that. I am absolutly speechless and impressed.
I just rebooted it manually again and it sill works. thaaaaaaaaank you so much
can you pm your paypal adress I like to buy you a beer or sth similar?
so the next steps would be run revolutionary and flash a custom right?

Haha don't worry about it.. and don't get too happy.. once it heats up again you may just have the same problem...
But for now yes, S-OFF the phone with revolutionary and flash a custom recovery, then backup, do a full wipe (boot, system, data, cache, dalvik) and flash a custom ROM. Cyanogenmod is a good place to start (need to flash google apps after flashing CM though)

[Q] Problems with installing blackout ics ROM Desire HD

So I decided to root my android desire hd phone and avail the benefits of blackout ics rom on my phone.
This is how I approached.
I unlocked the bootloader from HTC Dev.
I have the adb with me, adb devices, adb restart bootloader are working absolutely fine and cell phone was detectable.
I downloaded the aahk and blackout rom from xda forums.
But I am not able to use the aahk properly. It says in instruction to do a fastboot flash boot boot.img from command prompt with the source being the place where aahk is placed on the PC. But it still doesn't work, and probably this is the root cause of the issues I am facing.
I tried downloading the CWM to boot into recovery, but that also gave me an error stating cannot find the adbwinapi.dll file.
So after that, I did a factory reset of my cellphone and truly I got my first success and I was able to get into the bootloader and recovery.
I can reach to the bootloader screen (white screen+3 andro dummies), but when I select the fastboot option It says cannot find image(which image, is it referring to boot.img). I deleted the cache on my cell phone, but again things are pending from here on.
The description on this screen says S-ON and some other things. Does that mean the security is still on?
I have the rom loaded on the sd card with renamed to update.zip, but when I select update option from the recovery it again says cannot find image, rebooting!(what image this is referring to).
And after all this sequence I am down with a cellphone now degraded to froyo from ginger bread and back to stone age!
Please advise.

You have not done anything fine...anything at all. My advice is that you'd better start reading hard buddy or you will end up with a 300 bucks paperweight.
Use the guide in my signature to start.
Tip 1:If you really downgrade to froyo and you were running gingerbread, you might have messed the bootloader..can you boot in hboot in normal times or takes ages?
Tip 2:The Hack Kit can not be run with an unlocked bootloader...that is what the manual says. The manual is there just to avoid this.
If your bootloader is still unlocked, then you have to install CWM recovery, put the rom in the sdcard (no rename is necessary) and then flash the boot.img from where that file is located (I usually put in the PC desktop) and not from the Hack Kit folder.
Then, from CWM flash the rom normally and you will be up and running.
Unlocking the bootloader will not give you S-OFF....

I had this tutorial open side by side in your signature while I was doing it. (the noob one)
I can go into Hboot normal times.
I am writing it down here from the main website from where I downloaded the aahk. And it says
Unlock the bootloader using the HTC DEV bootloader unlock process.
Download att-ace-30-isboot.zip and unzip it (don’t forget to check MD5)
fastboot flash boot boot.img
relock bootloader
But just now you told me that it should not be run on an unlocked bootloader! I am a little confused.

the phone is now stuck at signature verification. I reasearched for it but could not find a viable solution or an exploit that can overcome it(though everyone seems to be suggesting to install CWM recovery)
Not taking any chances to convert my phone into a brick! Whats the best way.

I am following the steps sequentially as mentioned in that link by sashank. The bootloader is partially unlocked due to the HTCDEV process.
Couple of other things that I noticed. The android version is still at 2.3.5 however the device was shipped with Froyo. My mistake to have said that it is downgraded to froyo when I did the factory reset.
The facebook for HTC Sense thing is jacked up big time, I cannot find that in peoples app.
The device has (believe me) gained speed. pretty strange.
Once I reach home 3 hours from now, i'll update this thread and we can connect through Teamviewer so that you can have a look.hope thats cool!

[Q] Desire HD in bootloop obscure problem

Hello all!
I may be new to XDA, but i lurk a lot... And over the years this is the first time i've ever needed to post.
Right.. So today i bought an "HTC Desire HD" or 'Ace'
It was on Froyo (2.1?) S-ON and hboot 0.85 or something
I tried using AAHK - Which is fine, I've used it before successfully on my other DHD.
This time it was upgrading/downgrading a radio, error'd and quit.
It then restarted and bootloooped.
I tried Factory Restore did nothing
I then tried using many and various RUU's but i always get Error 131 or Error 190
I tried making a GoldCard to boot the phone still nothing
I also tried the PD98IMG.zip in the SD card (Tried with GoldCard too) Still Error 131
GoldCard does work as have tested it on another phone.
Currently sat staring at HBOOT wondering what the hell i can do to get it too switch back on!
The phone is locked to Orange UK with S-ON
The file that i believe to fix my phone is called "RUU-Ace-Orange-UK.18" something, but it just doesn't exist. I've searched all of google and only found dead links.
Just a little motivation, I'll donate to whom ever provides the fix for my phone my old Xperia Mini e10i! Thanks

AAHK is retired, and the server hosting the files it needs has been pulled. Without S-Off you can't flash radios. Are you just trying to root? If so, you can unlock your bootloader, flash a recovery, and flash a rooted ROM from there. You can't flash radios, but you can flash custom ROMs. The link in my signature has more detailed guides.
EDIT: but you will first need to update your hboot.

Please link me to hboot update, I've looked around but all links give me "downloadmanagerS.exe" :/

I believe that because your hboot is too old, you need to create a gold card to flash a RUU that supports hboot unlock. How to do that is beyond the scope of my knowledge, and due to the fact that the guy who used to handle all this stuff (glevitan) is no longer active here, you may just need to hope someone else shows up. You could try to look through his posts for that info.

So my phone is dead then D;

Basically you need to create a Goldcard and upgrade your bootloader.
I also have a Orange DHD and i am S-Off'd using another methord but the difference is that i have sense 3.0.
But due to your phones CID being ORANG001 you'll need the goldcard as there is no orange RUU firmware only HTC generic firmware.
Shot a PM if you still need help.

[Q] Could use help with S-OFF and Firmware

I got the bootloader unlocked with HTC Dev and rooted, installed TWRP. I installed Revolution (?) rom but had the restarting issue I presume because of the firmware being incompatible. Searching ways to achieve S-Off leaves me a bit confused though. Could someone hold my hand through the process or direct me to where I can update my Firmware and apply the newer Roms please? Thanks.

OMG do I agree with that post! When you ask about how to do this, they point you to a thread with 300+ post and say its in there, go read... Ive been reading for 2 freaking days and Im more confused then ever!!! CID, SUPERCID, brick without them... NO explanation from there. REALLY!?
Now some people go OUT OF THEIR way to help you, where others seem to just say search the forums. With any of the searches, there is 4000+++ hits, it would be time to upgrade before I read them all. Ive read. Im still reading. Heck, I'm about to ADB back to stock to by pass s-off because of the lack of info, or its scattered across 5 or 6 threads. Sorry for the rant, but Im tired, sleepy, and cant find the info on the threads. Ive done my time reading, came out worse then I started...

Guys, I know your first few weeks at xda can be frustrating, but there are reasons why we do it this way and why requests for hand-holding don't go over well.
First, this is, as the name says, a developers' forum where a certain amount of technical knowledge is assumed. All of us were noobs once, but we got past that by reading and asking intelligent questions, not throwing up our hands and begging to be spoon-fed. If you get less-than-helpful responses, it's often because what seems baffling to you is a question that gets asked regularly to the point that people get tired of dealing with it. S-off and firmware updating are in that realm.
Second, and more importantly, once you go s-off and start mucking with firmware, there is a very real chance of bricking your phone if you're not careful. So having a solid understanding of what you're doing is critical. The people who brick are the ones who rush the process and miss or skip important steps because they don't realize why they exist.
Now, having said that, I can give you a little guidance.
S-off for the M9 is pretty idiot proof at the moment. It's only possible through a paid app, Sunshine. You download it, install it, and it will tell you if s-off is possible for your phone. If so, you buy a license for $25 and run it. Done.
Updating firmware is trickier, but this thread is the best place to start. Read the whole thing from the beginning (especially the first few posts), and if there's anything you don't understand, asking specific questions will usually get you helpful responses.
Good luck!

Good advice from iElvis to go slowly and try not to rush before gaining necessary knowledge .
Usually for example with firmware flashing thread all relevant info is contained in the first four posts written by original poster.
Basically if you are S on you may only flash firmware that matches your currently installed software.
When you have S off (as described above by iElvis) then you may flash any firmware, by changing cid if necessary.
Firmware flashing done in download mode via command
Fastboot flash zip nameofirmware.zip
Phone will flash part of firmware then reboot to download mode,
Then you enter same command again and remainder of file is flashed.
Then you're good to flash custom roms based on the firmware you flashed.

Usually for example with firmware flashing thread all relevant info is contained in the first four posts written by original poster.
Basically if you are S on you may only flash firmware that matches your currently installed software.
When you have S off (as described above by iElvis) then you may flash any firmware, by changing cid if necessary.
Firmware flashing done in download mode via command
Fastboot flash zip nameofirmware.zip
Phone will flash part of firmware then reboot to download mode,
Then you enter same command again and remainder of file is flashed.
Then you're good to flash custom roms based on the firmware you flashed.

I am not new to xda or flashing roms , but definitely new to htc device. The problem is Alot of threads don't seem to explain "Why" .
your quote here has explained something so simple, that unfortunately was made to sound so complex in some other threads. Also many threads give slightly differing or slightly incomplete instructions. thats why I notice many people asking for a "FULL guide" and even some people offering to "donate if you can help me step-by-step update firmware" .
So , can i ask, just to clarify, after S-off, then SuperCID, we can flash any firmware update from any region? eg If i am from 1.32.710 i can flash 1.40.401 firmware? And ONLY then i can flash a custom rom that MUST be 1.40.401?

Yes, you can flash any firmware for your model. You can't for example, flash cdma firmware on a gsm phone (nor should you try).
But you don't necessarily have to match rom to firmware. It's advisable for best performance, but not always necessary. in this case, however, there is a conflict between firmware and kernel across 1.32 and 1.40—they need to be the same. That means you can run a 1.40 rom over 1.32 firmware as long as you have a 1.32 kernel running (this is my current configuration). But if you have 1.40 firmware, you pretty much have to run a 1.40 rom.

I am missing somethihng some where.. Ive tried the steps above, although no "guide" said anything about supercid. However, Ive tried to flash the firmware, and i do get a cid mismatch error. So I'm stuck and lost. I dont know what to do... Cid is being reported differently depending on how I get it, Adb reports htc_001, the app and the scrip report CWE_001, and I cant seem to find anything to flash to it. Im literally pulling out my hair.
