Root [Guide]ROOTING HTC android 2.2.1 or lower with unrEVOked - Windows (updated 20th December 2012)

[SUroot]

I rooted my phone with the help of SUroot when I first got it. Was asked to do a friends last night as he could no longer install anything due to lack of memory. Followed this guide exactly several times without success. Then the penny dropped - the phones memory was full. We uninstalled some of the larger apps and tried again. Worked a treat. New rom flashed.

So just to add - if you are having problems check you have some free memory on your phone.

Indeed. In fact this is mentioned in the accompanying rooting FAQ.

Other UnrEVOked errors...

There are other errors involving "failed to unlock NAND" or containing "MISC" or "backup CID". Although there are lengthy ways to overcome these which often will not work, it may just be as well to downgrade using teppic74's downgrade tool (GSM ONLY), to 2.1 and try with an older unrEVOked version.

Another error received is "Internal error: installing package failed." This can sometimes be down to there not being enough space on the device in "internal storage". You can delete some apps or even wipe as a possible work around.

I know, but I never read the FAQ until following the instructions failed.
We got it done OK in the end though.

Excellent guide.

Was wondering if i could get some advice. I have a new HTC desire and would like to root it and subsequently get rid of all the orange rubbish on it.

Been looking at the guide and I looked at the PVT and i have a four one. but the terminal application recommended doesnt work, so i tried a different one, but this gives me permission denied. What would you recommend that i do ??

Cheers

 

[SUroot]

When you say "Terminal emulator" does not work, what exactly happens?

You can follow this:

Do:
1) Pre-requisite - Download SDK
2) method steps 1-5 (except in step 1, do not boot to recovery, just connect phone via usb)

Then type the same command:

cat /proc/mtd

just read the link u posted and thats the one i followed so im still non the wiser wats going wrong?? sorry im a noob when it comes to this.

 

[SUroot]

When you're connected in HBOOT, in device manager can you see "Android 1.0 device"?

Did you install HTC sync then remove the application (ONLY) via control panel?

 

[big63vis]

yeah i did that,cud see android device in hboot

 

[SUroot]

reboot the pc, reboot the phone, connect phone in another USB socket. Try that.

 

[big63vis]

ok ill try that,dus it matter that my phone is updated with froyo

 

[SUroot]

nope. Well providing you're not using an old version of unrevoked, but you would get a "is your firmware too new" error, not "waiting for device"

 

[big63vis]

ok ill let u know how it goes

 

[big63vis]

isnt working,dont suppose it matters tht im on a netbook doing this

 

[SUroot]

Providing its windows it should be ok, unless the USB ports aren't good enough (possible). Have you another PC?

 

[big63vis]

yeah ive just taken it all apart the other day lol,ive sent photos from my fone onto here via a usb adapter

 

[SUroot]

Yeah, also we know that it shows in device manager so we know its picking it up. On laptops (and front USB ports on desktops) they are often underpowered so basic connections work fine, but more advanced stuff (like rooting) these ports are not sufficient.

It may be worth trying it on another PC. If it still happens, we know its not your laptop. Its your phone. (or you )

 

[big63vis]

just checked my netbook spec and they r 2.0 usb connections the same as the pc.

 

[big63vis]

this is the only bit of the process i didnt fully understand so i got feeling i done something wrong here

Essential information

Current Android Software version

• Settings>About phone. We need to check if your software is the ARA build (ARA 2.xx.415.x) this is the Arab build

Hboot version, PVT and Erase size.
​

• Boot into Hboot (from off, hold volume down and press power)
• Make a note of your Hboot version - Must be lower than 1.06
• Make a note of your PVT version. If it is PVT4 you must now check if the erase size is 40,000
• "Download Terminal emulator" from the market and open it.
• Type "cat /proc/mtd" and press enter. It will return results of either 20,000 or 40,000

No thats not what I meant. I mean the USB's are underpowered often on laptops as are the front usb ports on desktop pc's.

Its nothing to do with the version of the USB.

If you had this version, you would get "Is your firmware too new?" so its nothing to do with that. Plus you're probably not on ARA as thats the Arab build.

Hboot version, PVT and Erase size.

• Boot into Hboot (from off, hold volume down and press power)
• Make a note of your Hboot version - Must be lower than 1.06
• Make a note of your PVT version. If it is PVT4 you must now check if the erase size is 40,000
• "Download Terminal emulator" from the market and open it.
• Type "cat /proc/mtd" and press enter. It will return results of either 20,000 or 40,000

Which bit didnt you understand? This is just information you require.

 

[Rastaman-FB]

you have enabled debug mode right?
do not mount the phone as mass storage when connected to the netbook

can you take a screenshot of device manager on the netbook please

 

[big63vis]

[SUroot]

I'm goign to see if a Mod can take all these posts and put them in the rooting guide for tidyness.
