I have HTC Gratia with android 2.2 froyo. I try roth with unrevoked for htc aria which I download from site unrevoked.com
I instal driver and run unrevoked and after some time, restart, start root I get message "failed to unlock NAND flash". I try tree times but I alwys get same message.

Fourth i use UniversalAndroot..and Error
Is it posible to root my phone and please someone halp me to do that.
Please help me...
I looks like you are facing the same issue I am.
The new ROM released for the Aria has a much more secure HBOOT version, and a hardware device called an XTC clip is required for setting S-OFF which is the first step required to root the phone.
If you have a look through the thread I have here it covers what is required.
http://forum.xda-developers.com/showthread.php?t=1083209
note I am making life a bit more difficult because I don’t want to just deploy a pre cooked ROM, but the rest is there.
http://forum.xda-developers.com/showthread.php?t=1083209
yes you need to have your phone unlocked and rooted with an XTC clip
Hi everybody,
I also have the HTC Gratia and want to root it and install custom ROMs.
So what do I ask the guys at the store to do? To turn S-Off and that's it?
After security is off can I use tools like unrevoked to root my phone or do they have to use the XTC Clip for that as well?
So again, please correct me if I'm wrong. To install another ROM i need to:
1.) Go to place that has an XTC Clip and let them turn S-Off
2.) Use a tool like unrevoked to get root
3.) Install a ROM using Clockwerk ROM Manaer for example.
Thanks in advance

Once you gain S-OFF, you can flash ClockworkMod custom recovery. Check out this post and it's associated discussion thread on the steps to follow once you gain S-OFF.

1)can some one give me a link to the most easiest and current way to root? ((Ive looked every where and im not even sure what i am to look for)) Also i am fully updated.
2)after i root,,,can i keep the phone basically the way it is meaning stock and sense?really just want to root as to get rid of all the bloatware and possibly over clock it.
3)Is there away to back up the phone pre-root in case i dont like root and wish to return to stock?
Any help in these matters would be greatly appreciated.
So, here's my $0.02 worth:
1) The easiest is not the best. If you want to root your phone, you need to learn how to use ADB. It's not difficult. You will need it at some point in the future. Here's a link to root your Thunderbolt > http://forum.xda-developers.com/showthread.php?t=996616
Here's a noob's guide to ADB >http://forum.xda-developers.com/showthread.php?t=532719
2) Yes you can.
3) I'm not sure, but here is a link that will return your phone to stock > http://forum.xda-developers.com/showthread.php?t=1009423
Plus one on learning adb its way easier than youd think. i always tried to use the one click methods and whatnot but i finally had to in adb and it was way easier. no worry about something wrong with the auto root. also try mybackup app from the market. i used it to backup everything initially then use titanium bacckup after you root since its way better
Advice on rooting flashing Thunderbolt?
Hi all,
I am so frustrated With my Moto atrix 4g and the fact that it has a locked boot loader with the new 2.3.4 stock rom....I have a real simple question;
If I obtain a Thunderbolt, does Verizon force HTC to keep anything locked or make the Thunderbolt difficult to root, unlock boot loader and ultimately flash non-stock roms from XDA ?
If it is like past HTC phones then it should be a rom flasher's dream, correct? It is able to be unlocked and i can flash roms from this wonderful forum?
Please advise....much appreciated.

Bro, really, take just 2 minutes to look around! There's a root guide right at the top of the dev forum!
To the OP: learning ADB and some basic Linux commands will become more useful than you know. Like quickly and easily checking an md5 without some stupid app or a computer. Plus, jcase is very easy to find and very helpful if there's a problem. I really can't endorse doing it the jcase way enough.
***LOCKED*** On Bootloader
Hello All,
First of all thanks for the awesome easy guide !!
This is the first time I am rooting my HTC Tbolt and have had an issue to start with.
Used the instructions in the link below:
http://forum.xda-developers.com/showthread.php?t=1401959
After I download the 2.11.605.5 downgrade zip, I rename it, put in on the SD Card and go to HBOOT and it installs the downgrade just fine.
But at the end of this process, when I try to get the MR4 Radio onto the SD Card and install it, it simply does not happen. HBoot checks for the file, finds it, but nothing happens. I have renamed in properly and followed instructions to the dot.
I also noticed a ***LOCKED*** right on top of the screen and I think this could be an issue.
Can I go ahead and proceed with the Revolutionary Root Technique ? Would this be possible at this point ?
Is there anyway I can get Flash the MR4 Radio before I actually root ?
Also, would I be able to flash the MR4 Radio onto my device after Rooting ?
Any help is much appreciated !
Thanks in advance !
Cheers !
So here's my goal, to leave everything stock, with only root (su installed), so I can install a Verizon locked app, su, and perhaps busybox (I installed Terminal Emulator, but virutally no commands available).
1. Why use the one-click method over the method? As I understand it, the just unlocks the bootloader, so I'd need to install a custom recovery, to be able to flash an unsigned zip (su). I'd like to keep the stock recovery. Perhaps the process is to flash custom recovery, su, then restore stock recovery?
2. After I get root, will future OTA updates work? I'd like to not break that functionality.
3. It would be nice if would also allow you to just get root on your phone without dealing with the bootloader.
I've rooted and flashed my old Cliq, and it's nice having root when I need it. I also wanted to play around with setting the button led backlight levels, which via the command line requires root.
wrong section man
Well, perhaps I mis-understood the sections. Seems any questions having to do with roms/rooting go in this section.
Either way, questions still stands, and it seems your the resident expert for this phone.
Forgot to add, from all the other threads I've read, it seems there is/was some confusion as to whether or not the method would all you to flash a new kernel, not that I currently want to do that.
Edit: Since this is apparently in the wrong section, can one of the mods move it?
Edit 2: Thanks Binary100100 for moving this thread to the correct section.

you can flash kernels it is harder what else you need to know
How do I backup the stock recovery?
If I unlock the bootloader, do I need to flash a custom recovery to move forward? Or does unlocking the bootloader allow me to flash unsigned zips?
yes and its hard to backup stock recovery i got a backup all ready
So with an unlocked bootloader, I won't need a custom recovery? Just trying to learn, as it's a bit different than my Cliq.
you do need custom recovery sorry man i cant do much more explaing so busy butother people help you and look around read root threads etc
Well, thanks for the help so far.
If any one else is reading this thread, these are the questions I still have:
1. How do I backup the stock recovery? I know once I load a custom recovery, I will be able to backup the stock ROM.
2. Disregarding any warranty issues, why choose the method or the One-Click method?
3. Once unlocked/rooted, will DRM content still work? Will the Movies section in the Android Market still be available? It's not on my Cliq with CyanogenMod 7.
4. Once unlocked/rooted, will OTA updates apply correctly? Was anyone rooted on 1.36.531.5 and have the 1.36.531.6 update apply correctly?
5. Does the method wipe the device?
Thanks,

1. There is no need to backup the stock recovery. Once you flash a custom recovery there will never be a need to go back to stock. If for whatever reason you do want stock then just flash an ruu and you'll go completely back to stock.
2. You MUST use the method to get the unlock_code.bin file to unlock your bootloader before you even attempt to get root access. Once you have your bootloader unlocked you can make changes to the root of your device. With it locked you can only obtain a partial root which will reset itself after a reboot. For example, if you obtain a temporary root and remove a system app (like boatware), or two, or ten (whatever) then reboot they will re-appear. So you MUST have either s-off (not going to happen until an exploit is found and really isn't needed) or an unlocked bootloader. Once you receive the file from HTC then follow the included instructions to unlock your device. NOTE: You will lose all of your data when you unlock your bootloader so back it up first! After your bootloader is unlocked you can obtain root by one of two methods.
a) 1-Click root script.
This simply pushes an app called SuperUser.apk to the /system partition and a su binary file to the /system/bin directory which gives us root. Then download ClorckworkMod app from Market and install the custom recovery. From the app you can select "reboot to recovery" and install your custom roms.
b) Placing a custom recovery in a form of a PH85IMG.zip on the root of your external sdcard and boot into the bootloader. Then update the recovery.
Now with all of that being said I want to make something clear. The unlock method does NOT allow you to use the device for other carriers! You would still require the T-Mobile SIM to use the device.
3. Having root does have some disadvantages. Some roms may effect the ability to watch DRM movies, watch movies from Market, etc. Depends on your rom though. Check with the developer. ALWAYS make a nandroid backup prior to flashing any rom! That way if you don't like what you flashed you can always revert.
4. Okay... well I stand corrected.... this is the ONLY real reason to install the stock recovery. However installing an OTA update will cause you to lose root. Even with a custom recovery and a stock rom... if you receive a notice to install an update it will not work! The best alternative if you really really really want the update and lose all root then flash an RUU, do the update and hope that HTC didn't do anything to prevent you from getting root again. My best advice would be to wait for your favorite developer to update his/her rom with the update that you're trying to flash. That way you won't lose your data (shouldn't anyway) and no real risk of losing root.
With all that being said... I'm moving this to General because it's where all the Q&A's go.
Thanks for all the detailed info. I'd like root (installation of Superuser only) for the stock ROM. I don't plan on installing a custom ROM at this time. If I have an unlocked bootloader, how could HTC block root access? Couldn't I just flash an su zip? Ideally, I'd like to be able to swap recoveries out to apply the OTA updates. I kinda wish they had a code to just give me root access on the stock ROM.
I see the ruu thread, but am concerned about the source of the ROMs. Does HTC ever officially release a complete stock ROM?

IDK but I read your questions in a very slow voice like mr. mackey in southpark or something
anyways, why are you so worried about getting OTA updates?
a developer will eventually root and deodex it anyways.
You say you want to keep stock rom, but why don't you try the Custom ROMs which are basically stock ROMs on steroids?
You do realize when you apply an OTA update you lose your root access and there is a possibility that it'll be harder to even have your device rooted in the future.
For example, the mt4g, everybody got happy and updated to the gingerbread OTA, but lost root and nobody found out how to exploit it until about a month later or so.. and that is only by downgrading which is a tedious process that many, who don't know how to use ADB, have troubles with.
I believe the OTA updates comes with new bootloaders and radios, not only the rom, so it will lock your bootloader. (I think) that's what it does to other devices. Who knows if htcdev will work on all bootloaders. just my two cents, if you want full control of your device, unlock bootloader and root it. You can get every OTA update through developers here.

Man, hopefully I don't sound like that. I really appreciate all the step-by-step guides; but, unlike most people, I want to understand what I'm doing, not just run through the steps.

Well, I don't really want to wipe my device at this time, so that probably rules out the HTC Dev method and installing a custom ROM. I asked about the source of the ROMs in the RUU thread, but if the stock recovery would flash them, then they'd obviously have been signed by HTC. If software is available via an official source, why would I download it from a forum? If I can get Ubuntu from Canonical, I wouldn't go download the ISO from an unofficial mirror (or if I did, I'd verify with the md5sum keys posted by Canonical).
Since I am really happy with my device as it is, and the ease of updating via OTA, I didn't want to give that up, just for the couple things I want to do with root access.

Hmm, unless these devices have backup/secondary bootloaders, I doubt and OTA update would flash a new one, as an error during that flash could brick the device. It would seem odd that HTC would promise to unlock bootloaders, give an OTA update that would not work with their site. I'm not saying that it couldn't happen, just seems unlikely. Was the MT4G unlock done via? If it was an exploit to gain root, then I'd understand why they'd loose root.

HTC has updated their bootloaders via OTA on a few occasions. And we know that HTC and T-Mobile (along with other carriers) read these forums as well (shout out to HTC and our wireless carriers) so almost literally the day of an exploit is discovered and if HTC isn't happy with our findings what do you suppose they will do? They will almost always look for the safest way to update the bootloader and keep us from being able to use that exploit. Seeing that we still don't have S-OFF (and may never have it) they are obviously doing all they can to make it more and more difficult. That in itself is proof that they don't want us to have it. So would they push an OTA to keep us locked to S-ON if they can? You better believe it!
I can see them patching a hole that would get you S-OFF, but seems odd that they would take back an unlocked bootloader that they themselves unlocked.
I guess I'm ok with the offical unlock method without S-OFF, if the only things I can't do are flash a new bootloader, radio, or unlock the SIM. Did I miss anything there?
I don't get it, you say you want to use root on the stock roms, and now you're saying why bother downloading a stock ROM that is prerooted when you can download stock ROM that isn't rooted ota? What is the difference? You're going to want to root the ota updates and the developers are already providing it for you. it doesn't matter where you get it, you're gonna use some 3rd party exploit to root the ROM anyways.
You my friend seems to have a indecisive problem. I understand that you want to understand the process, but if you don't want anything to do with 3rd party developing you're in the wrong place. You're making your life very hard.
And i think that's about it about being s-on. It's more of the hardware functionality that is locked.
Think about it as a locked bios kinda... Lol

I don't need to use an exploit to root the stock rom. I can unlock my bootloader direct from HTC, flash a new recovery, and then flash the superuser program. That was kinda my point in asking in the first place... why use an exploit (one-click), when an official route is available?

Hi all!
I am currently on Mango 7720 with bootloader 4.5 and so I can't use HSPL.
I read that with an Y-cable it is possible to do it.
I need a stock rom for my mozart, as my firmware rev ends with 111 I need TMO-DE (T-Mobile DE). So this are my planned steps:
1. Connecting PC - SD card - Mozart using Y-cable, flashing it with this rom on the SD card: RUU_Mozart_TMO_DE_1.32.111.01_5.65.09.25_22.45.50_ RELEASE (taken from this thread)
2. Next step will be HSPL my device (thanks to step #1 it's bootloader is below 4.x) following this thread: http://forum.xda-developers.com/showthread.php?t=1195647
3. Now i can flash any custom mozart rom (hopefully).
Any reply if i am correct will be appreciated - the ones pointing to a misthought even more ;-)
Thanks,
UP
with 4.5 I think it's possible without a Y-cable, I didn't use one. I think y-cable is only necessary for 5.XX and higher.
I simply put device in bootloader screen (holding vol down whilst switching on) connected it to my computer and waited for USB to appear on the bottom, finally I flashed an older rom, like your RUU_Mozart_TMO_DE_1.32.111.01_5.65.09.25_22.45.50_ RELEASE
If this works you should have a 1.32 bootloader, you can then install RSLP/HSLP
If you need a Y-cable, it will not let you flash the ROM, as far as I know though this only happens with post 5.XX bootloaders
Hope that answers your question. Obviously make sure you follow the instructions for RSLP and HSLP carefully and fully understand that if something goes wrong (powercut etc) you have effectively bricked your device.
Otherwise best of luck.
EDIT: Obviously if you plan to use the RUU_Mozart_TMO_DE_1.32.111.01_5.65.09.25_22.45.50_ RELEASE, make sure your phone's original rom was TMO_DE (I assume that is T-Mobile Germany) Otherwise you risk bricking your device.

Thanks for your reply!
In the HSPL/RSPL thread i read that it will brick your device when using Mango ROM with 4.xx/5.xx Bootloader.
That's why i intend to use the Y-Cable. I would be lucky if i would'nt have to.
So you think I can directly flash the old NoDo ROM to downgrade the bootloader without the Y-Cable and then install RSPL/HSPL? Wow thanks for this useful information, makes it a lot more easier!
My Firmwarerevision ends in .111 - that's why i think it's TMO DE. Is there any other way to tell this?

That's what I did, as long as it's the same branding it will downgrade your bootloader to the one in the rom.

wait? My phone is factory unlocked, so my phone have unlocked bootloades isn't?
if no, please give me step by step tutorial, so i can install my custom xap. :silly:
Thanks a lot.
Factory unlocked only means carrier or sim unlocked. If your phone has dloader as boot-loader then there is no chance of installing xap-files. If your phone has qualcomm boot-loader then you can. Do a search in this forum to find out how to determine what boot-loader your phone has.

There are two conditions to install xap...
1. If your phone is brand new and not unlocked (refer case 2 and 3), then you can install XAP(WP application files) from MarketPlace only. There is not other way.
2. If your phone is dev-unlocked, then you can install upto 10 xap files of your choice. To dev-unlock a phone you need a dev account from microsoft which is by default paid. and you can use that to unlock upto three devices. It is good if you are a developer.
3. If your phone is rooted then you can install as many XAP files as you can. There is virtually no restriction for this. Simple way to do it is by installing CUSTOM ROM to your phone.
Once your phone is unlocked there are many ways to install a XAP.
1. XAP deployer from WP SDK.
2. other unethical tools, which I would not name here.
BUT sadly you need a very strong luck, if you are using a Lumia 800, that's too at 7.8. The best way is to get a dev-account. Register as a student; it will be free. if you are successfully registered, you can install upto 10 apps
THIS is a illegally legal way to unlock a lumia. Moreover installing unlicensed XAP is again illegal.
all
You may install a custom rom and you won`t get problems with installing Xap and use Appz by your choice.
