The Virtuous ROM includes all the stuff in 1.72 already. So there's no point derooting and going S-ON, just install Virtuous.

rmk40 already found a solution to rooting these newer builds, but it requires changes to the SuperUser app. He's submitted those to the author but there hasn't been a new version release yet.

Hm,I`m now on stock 1.34.405.5 Firmware (RUU_Vision_HTC_WWE_1.34.405.5_Radio_12.28b.60.140e _26.03.02.26_M)

but rooted and S-OFF with UBERROOT method!

Now if I flashing this Firmware I still have S-OFF but I lose

Root and can`t Root again right?

The same happens if I trie this Root and S-OFF method and flashing

If you are desperate to try it, nandroid backup, google "extract rom.zip from ruu" and install through recovery.

Glad there is a dedicated thread for this. I have applied the OTA (stupid me... should have read this forum first) and am now looking forward to getting root again so i can do SetCPU to underclock when screen off..

I'm happy to do any testing for those who get anythin working.
[G2 and Desire Z General] zappoo:
Also noticed in this new ROM (OTA) that when i plug in my wall charger, it goes straight into "CAR PANEL"?!

When i use the official HTC cable it does not - but when using a mini USB cable + micro USB adapter, it goes straight into car mode.
[G2 and Desire Z General] JPHCCFC:
Does this have the same issue if you just flash the radio?
[G2 and Desire Z General] maus010:
Because it gives me an error: MAIN VERSION OLD

So it wil not flash.
[G2 and Desire Z General] rmk40:
As long as you still have a custom recovery (i.e. Clockwork), I can help. See the thread I just created here:

http://xdaforums.com/showthread.php?t=886999

If not, sorry I cannot help. Obtaining root again is for the black hats around here. ;)
[G2 and Desire Z General] snudel:
I wont root my DZ since setCPU profiles dont work.
[G2 and Desire Z General] maus010:
Thanks for your help.

But the OTA update also flashed the bootloader and recovery back to stock.

The only thing positive with this update is the batterylife.

It hase improved bigtime!
[G2 and Desire Z General] zappoo:
Agree - battery seems heaps better.
[G2 and Desire Z General] DanWilson:
Is anyone working on this? Got my DZ and subconsciously accepted.

Am now :( because I need to keep using the damn power button to wake it up!

[G2 and Desire Z General] steviewevie:
There's a note in the manual for the DZ that says if you use an adapter it will think it's plugged into a car kit.
[G2 and Desire Z General] MacaronyMax:
You can still root then :D
[G2 and Desire Z General] thecarbine:
You can positively confirm that any new T-mobile G2 devices do not have the new unrootable 1.72 update? I mean like 100 percent confidence :D

I am looking to purchase it and don't want an unrootable device. Also, I agree that the new ROM will migrate over to the G2 at some point so I was wondering it these OTA updates are absolutely required? (I do recognize with s-off you can just reroot it)

Thanks!!!!! (this is my first post here :p)
[G2 and Desire Z General] keinengel:
Welcome to the XDA-developers forums!

The G2 stock ROM doesn't currently come with the same security measures as the Z. The OTA updates are not usually required and you can turn them off in Settings.
[G2 and Desire Z General] leoking3:
So , can we root the new update yet? Or is it just like for HD?
[G2 and Desire Z General] steviewevie:
Not yet, no. I imagine it's the same problem for the DHD, yes.
[G2 and Desire Z General] ClusterM:
HTC blocked root but hasn't fixed all annoying bugs :(

I am in the same **** :D please root 1.72 :D
[G2 and Desire Z General] waqypaqy:
Like an idiot I rooted my phone with visionary and then for some reason I decided to check for OTA updates. Found one and installed it. It was only until now I realised that the new update must've blocked me from rooting the phone again. :(

Can't wait for the new root fix now :(
[G2 and Desire Z General] Untouchab1e:
I am so sick of Sense, I really need to get my Z rooted but yeah, updated too!
[G2 and Desire Z General] STG777:
Mine to my z won't root either...
[G2 and Desire Z General] koekeloer:
If you already had permanent root and S-OFF before applying the OTA, it's possible to downgrade and apply root again.

Check my post earlier in this topic, #107

[G2 and Desire Z General] phatnoize:
Just bought my Z and did the OTA. Hoping the fix will come soon :mad:

Credits to all who are working on it
[G2 and Desire Z General] walid898:
We are all waiting for it !!
[G2 and Desire Z General] Untouchab1e:
I rooted using Rage. Not sure if I did S-OFF or not. How can I tell? I followed this guide
[G2 and Desire Z General] ohyonghao:
You can tell by turning off the phone and then starting it while holding the power button and the volume down button. This will get you into the bootloader and you should see S-OFF on the top right of the screen.
[G2 and Desire Z General] Untouchab1e:
Thanks!

Says S-ON, so I guess I am stuck with Sense and no Root. It seems all we need is for the author of superuser.apk to update his app though
[G2 and Desire Z General] Untouchab1e:
So cant someone poke the author? I need root so badly! Sense is really bugging me!
[G2 and Desire Z General] steviewevie:
Only if you had full radio S-OFF via gfree though. If you only had the "fake" S-OFF via eng hboot, then you will lose S-OFF in the update and won't be able to downgrade.
[G2 and Desire Z General] steviewevie:
Sorry, but that's a long way from all we need. That's just one piece of the puzzle. Superuser is just used to manage root, access, not to gain it in the first place (temp root).

The current rage exploit to get root in the first place doesn't work any more.

Also what needs fixing is unlocking the NAND write access again.
[G2 and Desire Z General] DanWilson:
How did rage's temp root work?

I really want to know that.

Also - anyone actually working on this? I mean, damn, it's been here for aaaagggeeeess.
[G2 and Desire Z General] steviewevie:
I presume it's being worked on, on #G2ROOT. But I haven't been through the logs to see what's being discussed etc.

Rage's temp root worked by forking (starting) a large number of processes, and something happens where it fills up all the process slots on the system, and the next process to start will get root permission. That next process is terminal emulator in the procedures given, so terminal emulator starts as root and that gives you temp root.

Presumably HTC patched the loophole ? I guess it's a kernel thing.
[G2 and Desire Z General] DanWilson:
Weird. I always wondered why it said "Forked xxx childs"...

I guess thats why.
[G2 and Desire Z General] rodolgo:
Has anyone yet tried downgrading with the stock root (back from October before the OTA) then restarting the rooting process?
[G2 and Desire Z General] MacaronyMax:
Oh wow thats awesome :D;)
[G2 and Desire Z General] steviewevie:
I'm not quite clear what you're asking. The problem with this new ROM is that unless you already had full radio S-OFF via gfree, you can't downgrade (because you can't get root to be able to hex-edit etc to force a downgrade to work). If you have S-OFF via gfree then you can downgrade ok, but that still won't let you root the 1.72 ROM.
[G2 and Desire Z General] MacaronyMax:
I think what he means has anyone tried the test/pre release ruu i think which was like 1.24? :D
[G2 and Desire Z General] maus010:
I've tested the 1.22 RUU without succes.

The new 1.72 rom won't let you downgrade to an older version.

Damn you HTC!! :mad:
[G2 and Desire Z General] CTCNetwork:
Hi,

Might be a silly question this, but would it not be possible to reflash the phone, in toto back to the previous ROM?

Such as the UK ROM that proceeded this update?

Does anyone have that ROM file backed up/copied?

[G2 and Desire Z General] maus010:
Like I said........the new 1.72 rom won't let you downgrade to an older version.
[G2 and Desire Z General] gnocchi_ny:
Super Noob Question

How do I know if I can root my device? Where do I check to confirm that I do *NOT* have the latest OTA version? My current Software Information is listed in the signature.
[G2 and Desire Z General] CTCNetwork:
Hi,

So on this basis, once "upgraded" these phones can't take any ROM whatsoever?

Des. . . ;)
[G2 and Desire Z General] steviewevie:
If you had radio S-OFF via gfree before the upgrade, then you will still have it after the upgrade, so will be able to flash different ROMs.

But if you didn't have radio S-OFF before the upgrade, you will be S-ON after the upgrade so will be limited to stock ROMs (and same version or later stock ROMs at that, it won't let you downgrade to an earlier one).
[G2 and Desire Z General] steviewevie:
It's the build number/software version in your signature. You are on 1.34, so you can root and S-OFF fine using the existing methods.

I don't believe Bell have rolled out this update yet. But in time I imagine they will (and T-Mo for the G2 too, etc, etc). So you may want to turn off your automatic check for updates on the phone.
[G2 and Desire Z General] rodolgo:
Yep, you got it right, that's what I meant. Bummer, I didn't s-off previously...
[G2 and Desire Z General] poochie2:
I'm dying of sadness, just got a used Desire Z and saw that it was updated :mad:

[G2 and Desire Z General] rtorbs:
Well you send yours back then, I'm holding onto mine.

Thats why you need to pop it in the microwave for 20 secs.....just enough to cook inside but not enough to melt the screen lol......:eek:
[G2 and Desire Z General] gnocchi_ny:
Thanks... I appreciate the quick response. I wasn't 100% sure about the version number but you clarified. I already turned off the automatic check for updates. I look forward to using gfree to root my DZ.
[G2 and Desire Z General] waqypaqy:
If your Android version is 2.2.1 and software version is 1.72 then your stuck with us. But by the looks of your signature you are on the safe side :)
[G2 and Desire Z General] Searcherx:
Oh no..

I just spent half a day trying different methods and tools to root my desire to eventually come across this thread?

Are there at least some different stock ROMs available from phone operators that are possible to use to flash over the latest HTC version?
[G2 and Desire Z General] steviewevie:
If you are already on 1.72 and do not already have radio S-OFF via gfree then sorry, but you are stuck until someone can at least get temp root working on 1.72 (at which point there should be a way to downgrade).
[G2 and Desire Z General] Searcherx:
Yes I understand there is no option to downgrade at the moment, but what about an 'upgrade' to the same version, different look 'n feel (stock T-Mobile, Vodafone, ...).. or that would just render my phone useless, locking it to the respective ROM's operator network?
[G2 and Desire Z General] steviewevie:
Once you are on that ROM, it won't let you downgrade to an "older" ROM. If you don't have radio S-OFF, then you won't be able to flash a custom ROM.

All of the current "same" versions of that ROM have the same problem. T-Mobile, Vodafone etc ROMs are right now "older", so it won't let you upgrade to them anyway (and unless you have SuperCID via gfree it will report that it's the wrong ROM for your phone anyway, and prevent you from flashing it).

Basically you are totally stuck for now if you are on 1.72, limited only to new updates of the same ROM, unless and until someone can at least provide temp root for this ROM.
[G2 and Desire Z General] snoopdobb:
What if I just post a paniced message in this thread without actually reading any of the posts in this thread? Can I downgrade? Can I root? We all know I can't read!!! :confused::confused::confused:

On a more serious note, I have to salute your patience, steviewevie. I would have spazzed out and cursed everyone and their mothers' for re-posting the EXACT SAME question over and over without reading a single post. Kudos to you! ;)
[G2 and Desire Z General] CTCNetwork:
Hi,

Indeed. All kudos to Steve.

But it seems quite diabolical that just one OTA update can "brick" your Desire Z to be so locked in.

Most of my experience is from ROM'ing Xperia X1's. Don't like one, you get another. Obviously after installing a different ROM boot-loader.

I and probably quite a few others didn't understand the significance of the Radio S-Off process!

Would it be possible though for HTC to reload the ROM as original?

Des. . . ;)
[G2 and Desire Z General] rodolgo:
I concur... note however that due to the wealth of information on this forum, it is very difficult to find the **right** information you're looking for. And frankly speaking, the search function is almost useless - results are often too messy. I guess that's the price to pay for openness. I'm not complaining though.

[G2 and Desire Z General] dhkr123:
Damned bell users.... lack the ability to process logic. Like if you can get BETTER phone service and PAY SIGNIFICANTLY LESS, you would actually be BETTER OFF.

Run gfree NOW (don't wait!!!), then you can take ALL the updates you want and will never get locked out ever!
[G2 and Desire Z General] dhkr123:
For all interested, as a result of generating a brick, scotty2 has spent a real good amount of time working on some REAL low level stuff on this hardware (pbl). Things that may eventually help us to recover from a RADIO brick... i.e. unbootable radio image. If this work comes together, it may offer a PERMANENT solution to anything that htc can *EVER* come up with... at least for this hardware... and the expectation is that it will work over nothing more than a USB cable.

Step one was accidentally generating a radio brick and learning some things about interacting with the pbl. Step 2 was to warranty the phone (though how he wasn't on a banned list with tmo is beyond me...) and dump the pbl. He is now working on analysis of the pbl, which will hopefully explain what it can actually do.

[G2 and Desire Z General] NoFatePPC:
what happens if you do a hard reset (factory reset) doesnt it go back to the rom , before the ota update? Or is the rom itself changed?
[G2 and Desire Z General] poochie2:
That will just reset the settings bringing your ROM to a brand new state, not revert the apps back.
[G2 and Desire Z General] steviewevie:
Good to know, I'm sure that if anyone can come up with anything, scotty2 can ! :D

If so, (although of course dhkr123 can speak for himself), I imagine it came from IRC #G2ROOT. Anyone can check out the log files to see what is being discussed, as well as logging in live.

A small update. It looks like the original author of the "rage" exploit (to get temp root) is working on this issue, see http://xdaforums.com/showthread.php?t=902941

No definitive solution there, but let's all keep our fingers crossed they crack it soon ! Keep an eye out for any other threads like this asking for input from 1.72 users.

(by "patched rage exploit", he means those running 1.72 where the current rage exploit has been closed/patched)

Wait.. So the links are for people who have dont the original exploit on 1.34 then updated or for anybody on 1.72 :D

Hi,

Just to add some cheer to those of us who have borked - sorry, I mean upgraded - our Desire Z's.

I have been keeping an eye on battery life (both before the upgrade and since. There is a considerable difference. I am finding that with similar use the battery now lasts about 2 days before needing an overnight charge. This was usually one day when the battery had dropped to between 10% and 20%.

I have also now, just received my extended power Mugen battery so should be enjoying 3 days of unfettered use.. :)

You have to gain temp-root with psneuter and then downgrade the firmware and then do the normal perm-root using gfree

[G2 and Desire Z General] djfoo000:
From what I understand, you guys already have root, but not s-off. The radio that you guys are on right now have the rage exploit patched, so a downgrade is needed.

Refer:

http://xdaforums.com/showthread.php?t=902941&page=5

read from that page onwards.

EDIT: Damn guhl99 beat me to it. lol
[G2 and Desire Z General] guhl99:
Well just to make this a little bit more clear.

- not the radio of the new rom patches the rage temp-root exploit but the android system (patched zygote).

- the radio of the new rom patches the possibility to turn of the write protection of the emmc chip (done by wpthis or gfree)

Therefore you need to downgrade the radio to get permanent root (and s-off, super-cid, sim-unlock) because without disabling the write protection you can not write to /system to gain permanent root.

And to downgrade you need to change the version information in the misc partition (done by misc_version) which can only be done if you have temp-root.

So enough details - happy rooting
[G2 and Desire Z General] maus010:
I need some help over here :-)

I'm a noob to the whole ADB thing.

When I type ADB DEVICES it gives me one listed device. So thats ok right??

Then I type ADB SHELL and at the next line I get the $ symbol.

But when I type ADB PUSH PSNEUTER etc. it gives me: permission denied.

So what am I doing wrong?

And where do I have to extract the psneuter file? Do I have to put it in the SDK/tools folder??
[G2 and Desire Z General] Xtreme XL:
So if you already have S-off because you used Gfree before the OTA 1.72 update and you use the new root patch you'll get permanent root or only temp root??
[G2 and Desire Z General] YOSEFE:
That is my question too.

Any answers please?

Thanks.
[G2 and Desire Z General] guhl99:
I answered the question already in the other thread where the user of the above posting asked the same thing again, but now also here.

adb is a program that is part off the Android sdk and is run on your pc. to see how to use it please follow this thread: http://xdaforums.com/showthread.php?t=865685
[G2 and Desire Z General] guhl99:
You only get temp root by this exploit but you need it to get perm root again.

If you already have S-off then you don't need to use gfree again as your system partition is not write protected by the emmc chip.

But you still need to perm root again.

You have to do the following on your pc (using the files from the original gfree_temp-root.zip)

("$" and "#" represent the prompt and should NOT be entered as part of the commands. On a Windows machine, a "C:\>" prompt is shown instead)

$ adb push su /sdcard/su
$ adb push Superuser.apk /sdcard/Superuser.apk
$ adb push busybox /data/local/tmp/busybox
$ adb push root /data/local/tmp/root
$ adb shell chmod 0755 /data/local/tmp/*

Then do the new method to gain temp-root as describe her http://xdaforums.com/showpost.php?p=10428115&postcount=54 till the end of the topic 4 and use THIS ROOT ADB SHELL to do

# /data/local/tmp/root

This should make root permanent on your phone again.
[G2 and Desire Z General] YOSEFE:
I went to the link and updated accordingly, however my issue is now with chmod 777. I get "unable to chmod /data/local/tmp/psneuter: no such file or directory". What have I done wrong?

Please don't give up on. Am new to this whole Android excitement.
[G2 and Desire Z General] guhl99:
You are supposed to do the following commands ON YOUR PC while being in the directory where you downloaded psneuter and misc_version to:

adb push psneuter /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/psneuter
adb shell chmod 777 /data/local/tmp/misc_version
adb shell /data/local/tmp/psneuter
adb shell

If you still have problems and can irc than try to find me on freenode at #G2ROOT and i will try to guide you.

Hi,

Or if we have upgraded to 1.72 is what is being currently mooted as the means to re-root going to affect the new improved battery life?

From what I have been reading, the re-root involves changing the radio? Is that change responsible for the improved battery, or some other change?
