how to downgrade?? - Sprint HTC EVO 4G LTE

i recently had to get a replacement and without thinking i installed the latest update, I can still root it of course but i like to have a stock ICS backup to use Freedom IAP since its always been buggy on JellyBean for me. on ICS it works completely fine. can i either re-flash the entire phone? i used to do that all the time on Moto phones. or would just flashing a stock ICS rom work??

Best option is to go s-off. Then you can go from whatever rom you want to any other one easily.
If you have the latest update (3.16) and are still s-on, there is no way for you to go back to any ICS rom.
If you are on 3.15, you should be able to flash any ICS based rom or backup.

never mind

[Q] OTA ICS on AT&T Stock Rooted via RoloRacer Method

Will AT&T GNotes running stock I717UCLA1 rooted by RoloRacer's method (no tripping of flash counter) http://forum.xda-developers.com/showthread.php?t=1518962 get the official AT&T OTA ICS update when available? Or will these phones need to be unrooted to get the update?
Thank you.
generally, rooted phones do NOT get OTA updates, but since this hasn't been released yet, no one can answer your question.
let us know if you get it when the ota gets released, ok?

Certainly!
I keep checking for an update daily, hoping that it will be available sometime this month. But, if it isn't here by the end of the month, I think that I will flash one of the custom ICS ROMs that are available.
If I decide to install a custom ICS ROM, will I need to first, unroot the device and then flash this new ROM? http://forum.xda-developers.com/showthread.php?t=1664980

No. You will need to be rooted to get into CWM and load a ROM...if You dont have CWM installed, install it via Odin. Be aware though that this will trip the flash counter, but there are ways to remove that notification
na, just root your phone, and start flashing custom roms..
the dev's here will incorporate any changes/improvements from the official release into their base roms once it ACTUALLY comes out
there won't be anything unique in the "official" release that the dev's here won't be able to use, if its an improvement over what they are doing now..
I already have the phone rooted using the mashi root method listed here: http://forum.xda-developers.com/showthread.php?t=1518962 Being a NOOB in the Android world, I'm not sure what needs to be done next to be able to intall the ICS ROM.
Since my Note is already rooted, can I install the ClockworkMod Recovery listed here, first: http://forum.xda-developers.com/showthread.php?p=23170524 and then install this ICS ROM? http://forum.xda-developers.com/showthread.php?t=1664980
Thank you.
I installed ClockworkMod Touch Recovery last night with success! Now I plan on flashing ICS later today. I'm going to try this one: http://forum.xda-developers.com/showthread.php?t=1664980

You don't need root for cwm. At all.
Download mode and recovery are underneath the os, only need root while inside Android itself

[Q] How to undo ICS firmware update?

Hello,
I updated my SGS2 to the 4.0.3 firmware from my previous 2.3.6 Gingerbread. After the update my phone lags a lot and the ICS keyboard for texting lags and just sucks.
How can I flash my ROM or whatever it is back to Gingerbread? I don't like this ICS and would rather run GB on my phone. It looked "nicer" in my opinion and ran much much smoother.

You can not undo the the update, per se. You can flash back to stock 2.3.4. If you want to do that, follow the guide linked in my signature to prepare the phone to return to the store.
There is no stock 2.3.6 available.
You can also flash stock plus root 2.3.4 or 2.3.6. For this, you can follow the guide linked in my signature about installing custom firmware without incrementing the flash counter. You would have to get the 2.3.6 firmware from the Download Repository.
In any event, since you will be changing firmware base, you will have to perform a wipe data/factory reset. The instructions are in the guide. You will lose all installed programs, personal settings, contacts, text messages, etc, unless you back them up.
Lol here comes the flood! Get the life boats ready! The "how do I undo this **** stock carrier updates suck wtf " revolution is here!

Once a person commits to dumping the stock 4.0.3 back to 2.3.4, it's a matter of time and reading before they will flash a custom rom.
ICS has too many added features to give it up. If you know that you can go back to 2.3.4 without issue, why not flash a custom ROM.
I believe you can call AT&T CSR and ask for help.
Should AT&T have provided the instruction for reversing back to GB?

Well, this is not entirely accurate. If you flash the stock 2.3.4, you can still do the OTA (over the air) 2.3.6 update from the phone (Settings -> Software Update, IIRC.) We just don't have it dumped and ready to flash from PC. Be aware that this will be a huge hit to your data, so you should use WIFI if possible (it's free at most McDonald's.)

If I flash back to stock 2.3.4 (without root), will I be able to use the OTA updates to get back to 2.3.6? Or will there be a problem since I used Odin to get back to 2.3.4?
Thanks.
Edit: Sorry, didn't see post immediately above me.

Yeah, I thought about that. I don't know if I want to get in that cycle of addiction
Any you recommend? I tried various ROMs with my Galaxy S, and it seemed like there were a few that had deal-breaker issues, like sleep of death and freezing, but it could have been the phone too. It was just hard to know which one to use.

CyanogenMod 9 (ICS) stable was just released. I've been running the nightly builds for three months or so and am quite happy. None of the crap Samsung Touchwiz bits...
http://get.cm/?device=i777&type=stable
DO NOT USE ROM MANAGER OR ANYTHING FROM GALAXY2ROOT_DOT_COM. MAKE SURE YOUR DEVICE IS AN SGH-I777.
Sorry about the all caps or if that sounds pedantic but I'm starting to think that should be in the signature of all posts on this forum.

+1 this is exactly what happened to me. Upgraded to at&t's ics, hated it, and it made me decide to root to get rid of it. As i was doing research on how to root I found xda, and have never looked back. I am now officially addicted and feel like a papparazi: always looking for new stuff to "flash"

Best method

I been running the international ICS for a while. This past week I decided to try the CM9/10 roms. Everything went well. I want to give the official ICS update a try. I am new to custom roms, what would be the best way to accomplish ICS update.
Edit-I tried to update via TWRP and CWM but for me neither way worked. I flashed recovery.img file through flashboot and then did the update manually. Just wish there was a way to get rid of that T-Mobile sound on boot-up.

You can try the manual install via this post as a start. It might still install over your existing ROM. Not sure if it checks for a signature though.
It worked over my rooted Honeycomb T-mobile ROM, but now I don't have root anymore as expected.

Australian DROID RAZR XT910

I have an DROID RAZR XT910 GSM/CDMA with the following stock ICS: 673.94.328.XT910.Optus.en.AU, Version 4.0.4, Build 6.7.3-94_SPI-328 and while looking at all the mods and roms out there I'm not confident in flashing this device because the version numbers are different and I don't wanna brick my phone (at close to AUD$800 I think you can understand why) so need help with getting JB onto it (impatient here in OZ, last round from GB to ICS took 6 months from advertised to actually going OTA here). Phone is rooted, have Titanium Backup and SuperSU installed but:
1: don't know how to back up the whole stock in case of failure and need to reinstall
2: not sure that any ROMs are safe to use in my phone (differing stock numbers etc)
3: what other software needed to make this happen
Can anyone please help!?! (where's that old interrobang when you need it)

Hi!
I'm an Aussie user but bought mine through Kogan (so it's a German phone). If you've already rooted the phone and have Stock ICS I'd recommend installing SS3.11 or BMM and running another JB ROM rather than try to flash stock.
There's heaps of threads with great ROMs on here and the Development thread:
http://forum.xda-developers.com/showthread.php?t=2162827
http://forum.xda-developers.com/showthread.php?t=2028020
Personally I use SS3.11 with CM10.1 as my daily and it's fine. I can also recommend AOKP4.22 which is now officially supported on XT910.
Benefit of this setup is that I can also boot back to stock whenever I want.
Cheers and happy flashing!

many thanks, as I don't want to touch the stock at all I'm using this method (ss3 and aokp/cm10.1 tri-boot {keeping the stock I'll have three systems})

This is a bit late to see this thread, but there is a thread for the retail.au 4.1.2 official. If you do a search of the forum with "retail" and "au" you'll find it. Stock rom that needs to flash a kernel first.
First be sure to root if you're still on ICS. There's a one-click root tool in the development section.
Requires BMM 0.3.4, from there you can install the recovery and reboot into it. It allows you to do a nandroid backup.

A little help needed please

I got a used Note 2 that was already updated to the mj9 version with the locked bootloader. I rooted it using saferoot and installed safestrap.. Been trying out the mj9 roms and I like the ones I've used, but I want to know if there's a way to update this still awesome beast of a phone to nd7 or higher. I've downloaded the I605VRUFND7_I605VZWFND7_VZW.zip file from samroms, but it's still sitting untouched because I haven't seen anything definite.. I'm currently running Alliance build 26 mj9 version, but I also have build 30 nd7 version and Nephilim.STABLE.EMJ9.ROM.v8.0-FINAL-R3Ds.zip
downloaded and sitting on my sdcard with the official nd7 update from samroms..
Basically I wonder if I can just Odin the official samroms nd7? If there is a bootimg I need to delete first? Can I wipe and install the alliance build 30 for nd7?
I suppose mainly I want to get a newer Android version going and want to know the best way to go about it.. The phone isn't activated with Verizon, and I only use it on Wi-Fi, not as an actual phone..
Any tips, suggestions, or ideas are appreciated. Thanks in advance to the best community out there..

Since your bootloader is locked (and the bootloader is unlockable on 4.3+), the only options I can think of for you would be to.... 1). either stay on 4.3 MJ9 with Safestrap and use 4.3 stock based roms - OR - 2). upgrade the phone to stock 4.4.2 and then root it with Ghettoroot and use Safestrap to run 4.4.2 stock based ROM's. (Due to having a locked bootloader-- you are forced to use stock based ROM's that use the stock kernel when using Safestrap). So, if your phone is on a 4.3 based bootloader - you have to stay with 4.3 based stock ROM's. Once you go to 4.4.2, you have to stay with 4.4.2 stock based ROM's.
My Note 2 is still on the 4.1.2 bootloader, so I haven't personally had to use Safestrap on the Note 2.... but I've read where others say that they've successfully used Safestrap on 4.4.2 after getting the phone rooted.
Personally, I prefer 4.3 to 4.4.2 on my Note 2. I could never find a 4.4.2 based ROM that didn't have some sort of bug that drove me crazy(ier). Either the bluetooth audio would stutter, I would get a lot of lagging with the UI, or would get poor battery life. However, many others report having good success with 4.4.2, so you might be happy with upgrading. I actually decided to come back to the 4.3/MJ9 based Jett ROM v. 3.0, as it does everything that I want in a ROM, works well with my Sony SW3 smartwatch, and runs very stable with great battery life. If you haven't tried out Jett ROM yet, you might want to give it a try (you can find it in the development forum).
Since your phone isn't activated - you obviously won't be getting OTA's, so you'll have to use ODIN if you want to upgrade. If you do decide to upgrade the phone to 4.4.2, you won't be able to return to 4.3 again due to the locked bootloader issue. Also.... if you upgrade 4.4.2, you may want to restore back to total stock 4.3 first and make sure it's wiped clean with a factory reset-- just to make sure nothing is leftover that could mess up the upgrade to 4.4.2.
Good luck!
Hey mattnmag, thanks for the info! It was a good read, and I didn't realize that if I upgraded to kit kat I wouldn't be able to downgrade back to jellybean if I didn't like it.. I've still got all the files I need except for the mj9 stock firmware, so I'll have to dl that before I get too crazy with this thing..
But I did dl the Jett ROM, and I'm gonna give that a run later tonight probably.. Just gotta get my backups onto the PC first just in case.. I hate doing full wipes though.. Because I'm lazy and don't like reinstalling everything lol..
What I'd really like it's too have my cyanogenmod back.. I had that on my old Droid RAZR and loved it..
