[Q] Easiest method to install custom ROM's for 2.2? - G2 and Desire Z Q&A, Help & Troubleshooting

Hi.
Much time passed when I unlocked my phone so I don't really remember how to do this again in my friend's Desire Z. I was looking for a tutorial but there is a problem. In this topic - http://forum.xda-developers.com/showthread.php?t=1055581 - goldcard generator link is dead and I don't want to begin procedure of unlocking until I make sure all the needed files can be downloaded. Can you provide me a method to make that Desire Z being able to use custom ROM's? Android version is 2.2.

Just go to the xda wiki, cyanogen wiki, or straw metals PDF guide, all of which will pop up in simple Google searches. This ois the only method you should use to root this phone. And the downgrade process may not be necessary if you are on 2.2 but depending on radio you might still need to, but being it only takes moments to do it can't hurt

OH BINGO! Cyanogenmod Wiki, I unlocked my phone from that site - I just couldn't remember. Unlocked perfectly, thank you.

[Q] HTC Desire Z to T-Mobile G2

Hi everybody, I'm very sad and desperate. I used a tutorial on CyanogenMod wiki to root my HTC Desire Z and flash CyanogenMod custom ROM into it. I just wont to try it. After few days, I decide to unroot my phone, but I was so silly, that I used tutorial I found via Google to do it but, the tutorial is was only for T-Mobile G2, now I have HTC Desire Z, with S-OFF and T-Mobile ROM and I'm unable to flash stock ROM. So, pls can anyone help me? Thanks a lot!
Why did you want to unroot?

I want to flash back stock ROM, so I think it's "necessary"... I'm so dumb. Now I flash back CyanogenMod, but don't know, how to flash back stock ROM...
You didnt do a nandroid backup of your stock rom? Could just flash that over then unroot from there.

I don't have any backup... Now when I power up my phone, it came with white screen with HTC logo on it
I unrooted a DZ today using the guide in the G2/DZ wiki
If you need any help hop over to #G2ROOT IRC
Already saw it, but correct me if I'm wrong, this tutorial is only for T-Mobile G2, because of this - PC10IMG_Vision_TMOUS_1.19.531.1 - but I have O2 Desire Z

Have you got to go back to stock for warranty purposes or did you no like any of the roms you tried?

I perform root only because HTC promise Gingerbread update till end of Jun, but nothing happend, so I did it. But am not satisfied with CyanogenMod ROM, it's drain my battery, and also I have troubles with Gmail notification.
OK, I'm going to try IRC.
GB update has just started to roll out.
If your not comfortable following the instructions in the wiki. #g2root is the best place, the guys there a very helpful and knowledgeable.

Am stupid, sorry for that! Didn't read the whole wiki entry... now I know what with part7backup... But I have one more question... Should I correct this command - /data/local/tmp/misc_version -s 1.19.531.1 - to /data/local/tmp/misc_version -s 1.34.405.5 - because as I realize, zip you linked me contain 1.34.405.5 ROM version.
Depending on your software version you may not need to use that command. Go in to settings>about phone>software info. And check your software version.
Sent from a phone that is not a HTC Desire Z
I have CyanogenMod 7.1 RC, but in location you pointed me, there is no SW info...
Umm, ok. If you put the PC10IMG.zip on the root of your sdcard and boot into bootloader. Depending on your software version it will either accept the PC10IMG.zip or give you message about your software version being higher than the other update you are trying to apply.
If it accepts the PC10IMG.zip let it flash then continue to follow the instructions in the wiki.
I would like to put a quick disclaimer here. I'm no expert on the ins and outs of rooting. So follow my advice at your own risk.

[Q] Rooting HTC Desire Z Gingerbread 2.3.4?

Hello XDA Community,
I am fairly new to the concept of rooting an android device and I have no idea where to start. I understand what rooting is and what it will allow me to do, but I just have no idea how to get started
I was looking around the forums and reading different topics on how to root the HTC Desire Z (or my G2 for short), but a lot of the topics take me to links to other topics, which have links to other topics which have a lot of technical things that are not friendly to a first time rooter (What is S-OFF/S-ON?? Why would I need to do that and how??).
I recently allowed my G2/HTC Desire Z to upgrade to the new Gingerbread 2.3.4, and to my understanding, there is no simple way to get this rooted. After reading the topics, I do see that there is a way around it, but I'm just at a loss as to where to start.
Is there anybody out there that is willing to help me out? If so, that would be much appreciated.
Thanks in advance!

The above linked method will work for you also. You'll have to downgrade first, then root, then flash a pre-rooted OTA build. That'll put you back to where you are now, but with root access.
I've just rooted HTC Desire Z - Android 2.3.3
1. You have to downgrade firmware 2.x to 1.3.4 ( http://forum.xda-developers.com/showthread.php?t=905261)
2. And then following these instruction in ( http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD )
3. Done
have any of you guys tried the gingerbreak?
from what i read its able to root any gingerbread device.
i cant post links as this is my second post. but im sure if you google it, you should find it.
i read under the techofweb result.
not sure if it works, i never tried it. Rooting my HTC desire Z voids my warranty
but if you guys out there try it, let me know if its successful.
thanks in advance.

Gingerbreak doesn't work on the G2 / DZ. And doesn't work on many devices.

What we're actually doing now to root is this :
2.3.4, temp rooting 2.3.4, downgrade to OTA 2.1, root that, flash new ROM.
You forgot the last step *PROFIT!* lol all kidding aside for the one who asked the pre-rooted ota is in the development section. don't forget to flash recovery and get titanium backup and all that good stuff first...well second after temproot if you go that method. DO NOT USE VISIONARY!
Also remember to do a nandroid backup of your 2.1 ROM if for some reason you want to go back to stock, or sending your phone in for warranty.

Hello everyone, I am using HTC-Desire Z with the android version 2.3.3
I really want to upgrade my phone to ICS. In case of doing the root, i want to know that, if i root my phone will it downgrade first to the Froyo??? If it will then can i upgrade to the ICS using the custom ROM process???
If anyone knows or understands my problems please provide me a solution and that will be appreciated..
Thank You

Yes search the threads and follow the wiki. The only safe way to root is to downgrade first using the method outlined in the wiki. The only way (for now and probably forever) to get ics on a desire z or g2 is to root

Help with rooting

Can someone walk me through for the steps of successfully rooting my desire z ?
Thanks
Sent from my HTC Vision using XDA App
There are so many easy places to find this information here if you just look around. Specifically the Android Development sub forum.
Cyanogenmod wiki for rooting the HTC Desire Z
The XDA wiki for rooting the HTC Vision/Desire Z
Also make sure you do not use the Visionary to do root as it has a high brick risk and don't install Clockworkmod version 5 as that has issues. Stick with Clockworkmod 3.0.2.4.
Another thing ... I suggest before you root your device, you read through a lot of the forum threads for your device so you have a better understanding of what your doing. I apologize if I'm treating you with kid gloves, but your question makes me wonder.
That guide is for 1.72 firmware though I am running on 2.42.666.8. How would I go about downgrading it?
EDIT: Also, what can you do with a rooted phone, I know you can do a lot just not the specifics.
Check the Development forum, there is a guide there for downgrading gingerbread OTA's

I was unaware you're phone had a later firmware on it. Yes, as you said, "can do a lot" with a rooted phone. For example you can install a custom kernel and overclock it to speed up the phone. You can install the latest version of Android on it so you know it's always up to date. I can't really think of anymore off the top of my head, but there you go. Rooting pretty much keeps your options open with your phone I guess.

[Q] Is it safer to use HTC unlock tool?

I just got my DZ back from HTC, and unfortunately they upgraded my firmware to 2.3. I took a look on the instructions on downgrading 2.3 to 1.xx, and it looks quite complicated and risky.
I know that HTC has released unlocking tool for DZ and I wonder if it is safer to use that. Anyone tried it before?
General opinion is that HTC's unlock tool is rubbish because (a) it is very restrictive and doesn 't really unlock properly, and (b) it officially voids your warranty.
The procedure in the Wiki is quite safe if you follow it properly. Read it carefully and come back and ask questions, before you try it, if there's anything you are not clear on. There are plenty of people here who can help you.

The thing is, that if you unlocked your boot loaders via htcdev, you will be able to get perm root and custom rom, BUT you will still have s-on. So apps like rom manager or boot manager won't work properly.
I recommend the wiki way too.
Sent from my HTC Desire Z using xda premium
I think you should use the wiki's instruction. It's actually a lot easier.
I had the same thought as you, tried HTC's unlocking method and could never get it done. Then I tried the wiki's instruction, downgraded, rooted and installed ICS all in about an hour.
Disclaimer: I am a noob, this is the second time I root a phone (first time was my SGS S a year ago).

+1 to all of this.
HTC Unlock does not give you S-Off, does not give you root, and you can only flash from ADB. Just do the Wiki method, and get real control of your phone.
I think you shouldn't use the htc tool....not the greatest result but lost your garanty!
Sent from my HTC Vision using XDA
Using the HTC tool is like sending a registered letter to HTC declaring you just voided your warranty. Stick to the wiki, IMHO!
Thanks guys. I decided to follow the wiki and got it successfully unlocked again! Got a custom rom back on!
Its warranty is not an issue to me as it is already expired

You did right with the wiki. If for any reason something went horribly wrong with a flash and you still had S-On bootloader, such as via htcdev unlock, you could have been screeeewed. S-Off makes your phone virtually bomb-proof, seriously it takes effort hard bricking a G2/DZ that's S-Off

[Q] upgrade from 2.2 to 2.3.x without rooting

It is a shame to say that I still use Android 2.2 with Kernel 2.6.32.21, Taiwan version since I bought the phone a year ago.
(Not until recently, I have decided to move on to Gingerbread because
I wanna use the the latest features in the NDK to write some C++ programs for Android.)
Without getting into trouble during/after rooting,
I tried an official OTA upgrade but it doesn't work.
I tried to ask HTC but they said they still don't have any official upgrade for my phone.
I am a newbie here in this forum,
Could anybody please kindly offer your help please?
It will be GREATLY APPRECIATED! I wanna make my App!!!
swimd
If there is no official Gingerbread for your phone (which seems odd ?) then you can flash a different official GB ROM onto your phone. But normally your phone isn't going to let you do this, because it will fail the signature checks.
What you need to do is to de-brand your phone so that it doesn't do these checks any more. I will see if I can dig out a link to a guide and edit it into my post, unless someone else beats me to it.

Steviewevie,
Thank you for your help in advance!
I can't copy and paste the link right now, but use the Search function in the Android Dev forum to find the thread called "Debranding Bell Desire Z" (it doesn't only apply to Bell phones).
Sent from my Desire Z running CM7.
Thank you for the help!
I have found that thread!
BTW, after a quick look of the thread, it seems that S-off is recommended...
Do I need to get "root" in order to do so?
Should I do that to prevent future trouble?
Always recomend rooting phones right away, if you have a custom recovery and an enginering bootloader you can save tons of headaches in the future when problems arise (as they often do) this of course is outside the fact that a rooted phone is a happy phone and certainly not an apple
Sent from my HTC Vision using xda premium
As demkantor said, getting S-OFF is a lot better because it gives you a lot more options for the future, even if you don't use those options straight away.
IMHO the only reason to use the goldcard method and not full S-OFF is if you are really worried about voiding your warranty or the S-OFF process yourself. But there's no need to worry really, since (a) you can easily reverse the process if you need to, and (b) lots of people here can help you through getting S-OFF (the XDA Wiki explains it very well, though it can look daunting at first).
Sent from my Desire Z running CM7.
+1 to the notion of just rooting the phone. Especially since if are software developer, I would think that you would want full control over your device. And if you have these type of skill, rooting will be easy.
As mentioned, root, S-Off etc. can be removed for warranty purposes, if that is the concern.
The Wiki method is generally accepted as the safest:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD
demkantor and all,
Thanks!!! ok, I am least I will go for S-OFF!
But, I need to be able to fully recover my OS and Apps,
I need to do some research on stock recovery and/or custom recovery...
Well, I think there is an official update to Gingerbread thou.. But I think dont think that version is in English as it is a Hongkong version.
