Root Downgrade 2.3.4 Gingerbread to 2.3.3 to prepare for root

[magdelaine]

I fixed the link in the OP so it downloads from the new file location. I also downloaded and unzipped it myself and I found no problems with it when scanned with Microsoft Security Essentials.

Does anyone know if the downgrade 6.01.605.05 instructions would work with versions prior to that particular one? Just curious.

 

[bberryhill0]

I think it's the same but with tacoroot. On the older versions you don't have to work through the bootloops.

 

[magdelaine]

Well, now that I've gone through the latest method, I'm actually glad for the experience. I now know some adb commands, much as I've attempted to not learn them. When my phone froze during boot this last time, I was like "adb reboot recovery, b***h!" No need to remove battery, etc. It was awesome.

i think manipulating the phone thru a command window is fun,once you get into a lil bit. im glad you had a positive experinece- that is honestly the responce i hope to get from guides that i write :smokingsomb:

i tried it twice as instructed and it wont work. I downloaded the zip from a third party but didnt put it in the root folder with the rest of the "HACK" because it did say to. I followed it as you told us to but nothing. It reboots in 2.3.4 and nothing changes. Scared me for a sec because it was stuck n a black and white HTC for over a min. WHOA. "That made my Bunghole pucker a bit" But a little help would be greatly appreciated. Thanks tried to upload all 4 shots of the CMD prompt but it wouldnt upload 2 or 3 so there are 1 and 4 of the process. REMEMBER i did it twice.

I don't see any images.

 

[scotty85]

I don't see any images.

i dont see any images,either. and for what its worth,you dont need to upload images. just copy the cmd window(right click,mark,highlight in white,hit enter) and then paste it here. in an advanced reply,the " # " will get you code tags that will make the code a lil easier to read,but thats not too big a deal.

if your on the latest OTA (6.01.605.5) then the tool in the first post will not work,as it is using zergrush,wich has since been patched. that may be source of your fustrations

if you are on 6.01.605.5,then use this guide: http://androidforums.com/incredible...y-downgrade-firmware-build-6-01-605-05-a.html

you can either unlock with htcdev to gain root access to downgrade,or you can use taco root,both methods are explained.

unfortuately,i cant offer anything more than that, as there are alot of details missing and alot of reasons that tools and exploits can fail.

if you dont want to try the lnked guide,start over with whatever process youre using,and then copy/paste the cmd window so we can see your inputs and the resulting errors/outputs and we will see what we can do

And post problems in Scotty's thread. Smh. I totally missed that this was in the older thread.

I'm trying to downgrade my DINC2 from Gingerbread 2.3.4 to 2.3.3 so I can root it. I've followed the instructions as given but my phone is still showing to be on 2.3.4. I've tried doing it with both Windows XP without admin rights (I don't have access to the password) and on Windows 7 with admin rights. Both times I get this error message:

C:\android\vwhk-12102011-c>adb shell /data/local/tmp/sh -c '/data/local/tmp/misc_version -s 2.18.605.3'
/data/local/tmp/sh: permission denied

Do I need to do a factory reset on the phone so I can downgrade the Gingerbread version?

Thanks.

I have tried for 4 hours now and so many different tutorials I can't get root on my inc2. God damn you Verizon I wouldn't even be doing this if you wouldn't be screwing us customers and giving us god damn ICS, it's been out a year!

Read the post above yours. Then read post 132

That guide will work,I promise. The htcdev guide in post 2 is a lil more straightforward, the taco root temp root is a little trickier.

I did this is rehash of a method I tried 4 hours ago. In the future I will get a motorolla or maybe even an apple. With Pete's tools I rooted that moto in 3 minutes, 5 hours later an no go with this piece of junk. I am tech savvy I work on my own computers but this has stumped me to no avail. I installed the zip files to c folder named android click on them and they disappear so fast I can't even read them. If XDA didn't charge $30 for one click root I would try it. 30 bucks is ridiculous when most things in google play are 6 bucks.

I just wish someone could do a literal step by step walk through because the vids on YT leave stuff out or assume you know steps and not everything is covered in any of these tutorials.

this guide is outdated.

see post #141

if your software version is newer than that,follow the 2nd post directions to use htcdev unlock as a source of root access to downgrade.

just holler in that thread if you have questions

 

[ShineHigh247]

Hey
Thanks for the guide. I did this on my DINC2 and it worked; Im back at 2.3.3 with Hoff & root access but having a couple problems.
1) Anytime I access an app that requires root access, it freezes upon checking.
2) Im stuck at 2.3.3. I go to "Update Software" and it won't update. Do I need to download 2.3.4 and flash that one over?

Thanks for ur time, peeps!
