Root [CDMA] How to revert to Gingerbread from ICS?

[HauntedDollie]

Thank you so much for letting me know this can be done! I spent a fruitless hour with HTC (again!) today with the CSR yelling at me and telling me it was impossible to go back to Gingerbread because my phone would no longer be compatible with something called "radios" now that I've (unwittingly, unhappily and pretty much nonconsentually) accepting the ICS downgrade.

Please, can you tell me how I can revert back to Gingerbread (which I was totally happy with and that worked perfectly) on my phone, which is an HTC Evo 3D? My phone is completely worthless for anything, even after trying to apply all of HTC's and Sprint's suggested fixes. Most of those fixes either did nothing (best case) or made things worse while not fixing anything. The only other suggestions they have entail me incurring more monetary expenses and/or being without my phone (which I pretty much am anyway now) for weeks.

I'd really appreciate any help you can give me!

Hi HauntedDollie and welcome to the forums. :ciao:

I don't know much about the HTC so I moved your post to the EVO 3D forums so you can get more help with this. Unlike the Galaxy S2, I think you need to be rooted to do it with your phone. Lots of smart people here that can tell you what to do.

Good luck!

Unfortunately I am on my phone right now and not my computer. I am probably the wrong person to be answering your questions but I agree you need to be rooted. You can pretty painlessly root using jerofld's guide here :

Honestly I did it with no prior knowledge.
After following this whole guide you will need to relock your bootloader. Sorry I don't have a link right now for instructions. Then download this file
Shipped ROMs


And run on your pc.

Then flash the stock gingerbread rom Dev-Host - Shooter_S_Sprint_WWE_2.17.651.5_odex.zip - The Ultimate Free File Hosting / File Sharing Service http://d01.megashares.com/dl/srTe15g...651.5_odex.zip

Sorry if the links don't work. I am on my phone. Also please don't take my advice as a sure thing. I am new to rooting but from what I've learned so far this is my best advice for what should work. You should probably wait for a mod to verify this info. I may have messed up as its difficult to put a guide together on your phone. I just saw you didn't have replies so I offered what I could to contribute to the Site. Good luck and feel free to ask if you have any questions

 

[Brian706]

I would have liked to get more detailed but it is really difficult on my phone. I'm sure a mod will be around to correct me or assist further but in case they aren't feel free to let me know if you need more info and I will be more thorough once I can get on the computer

excellent job! only thing i have to add,is that you will need to complete the optional step for s-off. unfortunately,this is a requirement if you wish to "roll back" your firmware to gingerbread. just completing the steps to htcdev unlock will let you root,and even flash roms,but the s-on phone will not let you go backwards in software build numbers,and simplyh flashing a custom rom on htcdev unlock,will not work,for the same reasons that james' ics roms werent working with his GB firmware,but in reverse. GB and ICS firmwares are not interchangeable,and unless a GB rom is specially modified to run on ics firmware,it will not work.

thus,s-off will be a requirement to achieve your end goal of going back to GB.

Ah thank you for that scotty! I will learn slowly but surely.

So can this be done? I'm trying to help a friend revert back to gingerbread... Is there a write up on this?

 

[DonB]

Yes it can as mentioned above

I assume that you are pretty familiar with rooting? I can put together a quick bare bones tutorial later tonight or tomorrow maybe if needed.
If you don't mind a little extra reading and skimming I will link you to help now.

Use this: http://androidforums.com/evo-3d-all...shing-evo-3d-roms-kernels-using-fastboot.html

Follow the optional step to get s-off.

(I don't think it's necessary to flash the rom in the tutorial. You just need s-off to run the GB ruu posted above. Make sure you download gb 2.17 ruu and not ics)

Then everything else you need to downgrade is in this thread: http://androidforums.com/evo-3d-all...installing-because-i-am-very-new-rooting.html

Like I said there is more info than you need in there. Don't be misled by the thread title. It eventually gets to the downgrade. I asked a lot of questions in there and DonB and Scotty85 provided a lot of detailed answers. It is a very useful thread in general especially for anyone new to rooting.

[3vodroid]

Yes it can as mentioned above

He has hboot 1.58..to be clear he needs to be rooted first? I didn't know it was possible to root this hboot

Oh that's a good point. I'm not sure if this will work on 1.58. I was already s-off from 1.5 before the downgrade.

Can't he still htc dev unlock? Then it's the wire trick. Or does the control bear software only work with 1.5?
If I have time I'll check. Going to a family thing soon for awhile and will be disconnected.

[DonB]

I don't believe JuopunutBear works on HBoot 1.58 as of yet, I could be wrong, I would post in the Devs thread and see what they say there

It says they support ics. But to be safe I also posted a link to their help chat. That might be a good place to verify.

 

[DonB]

Yep best to ask, there is always someone there to answer, they are pretty good from what I am told.

Also might be those who are flashed to ICS Roms on HBoot 1.5, why it is best to ask

It says they support ics. But to be safe I also posted a link to their help chat. That might be a good place to verify.

Wow awesome guys thanks! After my buddy saw my evo 4G lte rooted he really wanted to root his 3vo ( which is actually my old 3vo I sold to him) but then we realized he took the update. Thanks a bunch I'm going to give it a shot tomorrow and post results :thumbup:

Some how I knew you were going to say that.

Any luck 3vodroid? I would love to hear your results.
