Hi, I have basic knowledge about android so not a totaly noobish and I found a problem, which solution is described in very shalow way. I tried several of custom roms for DX, but I havent made nandroid backup, so I cant go to stock cos of !"£$%^ branding and now I would like to update for JB, primary hboot, which is I think only thing I need to use custom jb roms. Is there any way to update hboot without stock everything and OTA update? like update zip for my cid, but without stock rom and such?
As we don't have S-OFF yet, I don't think so. What is your CID? If you're in luck, someone having your CID will share his our her nandroid backup with you. Otherwise, you are left to wait for S-OFF or maybe ask your carrier for a RUU.

Give your CID. without it, you wont get help.
TMOB004, when I searched, I only found some people who were in need of stock rom for this cid too and didnt found anyone who acctualy has it.
Already tried not carrier, but service center and not succeded.

Hi, i have unlocked my Evo 3D using HTCDEV.com. I was wondering if it will be ok and safe to do the ICS OTA update when it arrives? Also could someone please advise me on my next steps to root my Evo 3D so i can use custom roms etc. All i have managed to do is up to yet is unlock my handset using HTCDEV.com, but i am unsure what further steps i need to take to root my device as there are so many different view and topics on the subject and it all gets a little confusing as what to do next. My HBoot is 1.49.0018, and i really dont know what to do next, so could someone be so kind as to advice on what further steps are required.........Thank-you for any help offered.
You might already have done this but just to make sure.
Did you flash a recovery.img?
I wouldn't bother, there will undoubtedly be a pre-rooted, cwm flashable version available within a day of the update landing.

Don't know if it will update the hboot but I suggest you downgrade and s-off it, if there is any method available for gsm...
And to flash a ROM, you don't need to be rooted. Just flash a custom recovery.img like 4ext, twrp, cwm. Then flash any ROM that you like. Almost every ROM here comes with super user. So after flashing a custom ROM made by a Dev , you will be rooted. If you want to root your stock ROM and don't want to flash custom roms for now, just flash a custom recovery first, then go to recovery flash this zip if you want SuperSU by Chainfire----------> http://forum.xda-developers.com/showthread.php?t=1538053
OR
this one if you want Superuser by ChainsDD---->

@iTzLOLtrain......I haven't flashed a recovery.img as of yet because i am unsure of the software to use buddy. If you could advise on which software you think is the best then i am more than keen to have a shot. This is my first time ever with android and i am really scared of 'bricking' my handset. I was under the impression if i wanted to install custom roms that i would have to root my device first?

Oops sorry....should work now.
Next step is to flash a custom recovery like 4ext which has no issues at all and then flash your su file this is how you obtain root access after this you flash a custom Rom

Ahhhh, I remember my first time. Do an awful lot of searching and reading. Once you feel like you can't get anymore info on a subject, then try it. You may have an issue, which most people on here will help u with when ask. If you came from that fruity company, you should be very happy with what Mr. Android and his developers can do.
I have a GSM EVO 3d (From Rogers). I am currently on Leedroid 5.3 Rom and Kernel.
I want to update to ICS (Finally...). I am S-off and i have 4ext running.
I have done a nandroid with 4ext and TI backup.
My questions begin here:
What do I need to do because i have Lee's kernel. Will Flashing just the new Firmware be enough, then just wipe dalvik, data and cache, and flash my new ICS ROM.
While im here I might as well ask, since we just got an official update. are a lot of the roms going to get updated and change significantly faster now. or is it still a waiting game for the release of the kernel source?
relock the phone,flash the stock recovery and flash the original ruu. you'll be able to upgrade after that. all the best:good:
Concerning your 2nd question: I think for sense based Roms, business will go on as usual, so we can expect new spin-offs of the popular Roms soon. But with CM9, aosp, et cetera it wont be easier now.
What does aosp mean again?

Huh? why would I want to relock my phone. I just want to flash an aftermarket ROM like cool sense 3.6.
I dont want the official ICS...
Why would you even suggest I relock my phone? even If i did want the regular official ICS (which I dont) I would not need to lock my phone.
To make it absolutely clear I have s-off and full root, and refuse to lose that. so if you dont know what your talking about carry on and dont reply.

I saw that, terrible telling you to update hboot. from the OTA.
Anryls thread firmware is stripped of recovery and hboot. http://d-h.st/9Po Install it, remove sd card, go into recovery, pop in sd.
Then just format all partitions except sd card in 4ext, wipe dalvich, install new ICS Rom.
You'll keep recovery, hboot and s off.
For OC kernels we will need source. :sly:

Newest firmware does not erase data, make a backup in 4ext in case you want to go back to gb.
As for why removing sd.
After flashing firmware, if you cant get into recovery, you hold volume down and hit power, the ICS firmware will try to auto flash again. So by removing sd you can scroll down to recovery in hboot, boot into 4ext, put sd card back, then flash your ICS Rom.
That firmware is based on the latest official ripped version, not leaked or test versions that have been around the last month or so.

I dont recommend you just flash the OTA. If you are rooted, you would either end up with a boot loop or lose your root.
If you are rooted, update your FW and flash one of the many ICS roms available in the GSM section.
I am Using HTC EVO 4G LTE in india under reliance india network.
I am using it for almost 2 months without any issues,
Last week i installed the Jelly bean OTA, from them onwards the device keeps on restarting every 5 min.
Its boots perfectly works stably for 5 min and then it re-starts.
I dont know what to do? .. Will downgrading to ICS will fix this problem.?
If so whats the best method to downgrade .. I am noob when it comes to this device. Please guide me.
I checked the forum but its with too many posts and got confused on it.
Honestly the first thing I would retry is a factory reset(if your not already s off) just make sure to backup any data you want saved onto your pc first. Perhaps even a phone call to your carrier as well that way they can document the issue so if you need a replacement later the paper trail will help.

There is probably ten thousand more people on here that can give you a more qualified answer than what I'm about to but I can tell you right now your gonna have to do the leg work and work your search bars...But I have recently been dealing with downgrading these EvoLTE's lately so I can at least help you narrow it down(a little).
Since you upgraded to JellyBean, I think the most important thing you will need to know is whether it updated you from the 2.13 firmware to the 3.16 firmware and whether your touch panel img was updated or not. If you were updated to 3.16 with the new touch panel, your basically going to have a heck of a hard time trying to downgrade to ICS...You'll have to get s-off and use a linux/ubunta live cd to downgrade it back to 2.13 so that you can then load a ICS rom. (BTW, if your in this boat, good luck because until they come up with a easier way to downgrade(if they ever do) it seems to be no joke, I wouldn't even attempt it, but I'm pretty much a noob to this stuff)
If your still, hopefully, on 2.13 , then all you should have to do is unlock your bootloader, and add the ICS rom to your sd card and flash a TWRP custom recovery then flash/install the rom through the bootloaders recovery(TWRP recovery). I would recommend the MeanRom ICS rom, it's easy to find and a great ICS rom that is basically stock. That or hunt down a stock 4.0.4 rom. Good luck.

Most likely not. When the EVO got the official update to software version 3.16, the firmware that came with that update included an update to the touch panel. If you have the updated touch panel you can only use ROM's that are software version 3.16. Using anything else will render the touch panel inoperable. Your best bet, as stated above, is to get S-off. Once you do this you can install the previous touch panel driver and flash an ICS ROM. You can leave everything else as-is. There is no need to downgrade your firmware.

You need to restore an earlier firmware. Follow the instructions in this thread http://forum.xda-developers.com/showthread.php?t=2355814. On page 5 i posted a firmware that replaces the same partitions (other than system) that the GPe conversion changes out. If you don't want to change you MID just change the android-info.txt file to match your current MID (PN072000) and it will flash.
Good luck...if this helps let the folks in that thread know, and as always love the thanks button.

No...just system and boot usually. You can grab cache and data too...but not the other partitions. Be scary always writing the firmware on restore. Mucking with firmware is risky business.

I would suggest reading up (and making sure you understand all the terms and processes) for at least a couple hours before trying anything on the phone.

If your talking about ROM, then take a full backup of your ROM before flashing custom ROM using titanium/nandroid etc.
Or if your talking about root,
Just unroot using unroot apps from play store or the respected app you get after rooting.

As the above reply stated, it depends on what you are talking about.
If you just want the stock ROM, recovery, etc. one option is to relock the bootloader and just run the RUU. It will return you to stock software. The only thing not "stock" will be the bootloader will say RELOCKED instead of LOCKED. You need s-off to make it say LOCKED again (after unlocking it).

You can return to stock with a RELOCKED bootloader with s-on.
You do need s-off if you want to make the bootloader say LOCKED as it was from the factory. But the only reason to ever do this is for warranty purposes. And if you bought the phone from AT&T, you should note that your warranty is through AT&T, not HTC. And AT&T doesn't give a crap if the bootloader is unlocked, or whatever (folks have even successfully sent in phones for warranty with custom ROMs on them).
If you are seeing warranty service through HTC (you didn't purchase from AT&T) that is another story. But that is the only reason I'd bother going back to LOCKED.
In normal usage, I recommend leaving the bootloader UNLOCKED as it give you more flexibility to flash ROMs whenever you want, etc. The only reason IMO to relock the bootloader in normal usage is to run the RUU.
S-off is nice have if you want to flash radios, modified hboots, and some other things (you also don't need to relock to RUU with s-off). It certainly doesn't hurt, and some folks like to make the phone as customizable as possible right away. In fact, I did s-off to the phone the second day I had it (although s-off was free back then). But for you, its not strictly "needed" at this time unless you want to do the things mentioned.

The baseband isn't determined by the ROM, its determined by flashing a different baseband/radio (which requires s-off).
There are some folks that have had issues on AT&T's LTE network using some custom ROMs. Namely, not receiving or sending voice calls while on LTE. But this seems somewhat random, and not the ROMs fault per se; but probably changes that AT&T is making to their network. The most you can do is flash the Skydragon ROM, and if you have problems, try another ROM or revert to stock.
Make a backup of your stock ROM with TWRP before you flash anything, to be sure you have something to revert to if you have problems. This is good general advice before you flash any custom ROMs, root mods, etc.
I'm using the ROM your linked (Skydragon Sense 7) on AT&T, and it works fine for me.
