[Q] Root access lost after flash doomkernel - Xperia Arc Q&A, Help & Troubleshooting

Hi Team,
I've been looking for about an hour now. I've lost my ROOT right after I flashed doomkernel and installing the update zip. I'm seriously wondering what went wrong.
Can anyone shed some light?

Which update zip? If you're flashing a ROM then use 'flash zip from sd card' rather than an update zip, it let's you choose what to flash.

That's what I've done in 2 separate occasion and I still loose root access.

[Q] Going from stock Incredible to unrevoked forever to prepare for official Froyo

I'm not in a rush to hack my Droid Incredible right now, but want to keep the possibility open for after the official 2.2 comes out, so it seems the recommendation is to install Unrevoked Forever since we don't know if the Dinc will still be rootable after the update (I actually believe it will be eventually, but no guarantees). I am NOT planning to install a custom ROM right now, my entire goal is to have S-OFF and then go back to stock enough to catch the official OTA when it comes.
I've been reading the instructions (and the warnings) and just wanted to make sure I've got the idea before I do anything. Can anyone point out any flaws in the steps below:
1. I downloaded the HTC_Incredible_Downgrade.zip from xda forums which I believe has the stock recovery PB31IMG.zip (146,445,757 bytes).
2. Install unrevoked3 to root the phone.
3. Download unrevoked-forever.zip. Install it with the custom recovery that unrevoked3 installed.
4. reboot and see the S-OFF setting
5. Then use the custom recovery to install the stock PB31IMG.zip from step 1.
So before I do this I want to make sure:
* Will I then be back to stock in every way except that S-OFF is set?
* Will any of this procedure wipe my phone clean so I lose installed apps and data?
* Am I then ready to catch the stock OTA install of Froyo when it comes out?
I suspect a bunch of people are thinking of doing this right now.
Thanks in advance
Steve
Welp
Remember that step 2 is far more involved; you need the special HBOOT drivers, and no HTC Sync.
I believe the 3 stars are:
* Yes
* No (since Step 5 is just flashing the original recovery)
* Yes
Which step do you expect to wipe my phone? I wouldn't have expected the rooting part to wipe it since I'm not talking about installing a custom ROM. I was more worried about the recovery to stock to wipe it.
Whoops
Whoops ... misread your step 5. No, you should be fine.
you dont really need to flash the entire stock rom just the recovery it can be found at http://adrynalyne.us/ here is a direct link http://adrynalyne.us/files/recovery/stock/PB31IMG.zip
Edit: in your step 5 you will need to use hboot to install a stock recovery
ps the stock recovery only is like 3.3mb the one you have is 140mb and will wipe your phone.
Uhm, you can't flash one part of the PB31IMG.zip, so if it's 146MB, it's most likely a system image with wiping data and cache, so yes, it will wipe your phone. You can find a stock recovery only PB31IMG.zip somewhere on the forums here. Search around.
I'm currently rooted with unrevoked3 and unrevoked forever. I have yet to mess with my radio or flash any roms. So to be eligible to get the over the air update I need to just flash that stock recovery zip?

Yes.

oops. lol. delete.
OK, unrevoked3 and forever both installed now (everything went VERY smoothly), haven't done the recovery to stock yet.
So I notice that I've got the Superuser Permissions app installed now. Do I need to unroot before I can do an OTA update to Froyo, or can I keep root and still do the OTA? If for some reason I wanted to give up root at some point what would be the minimum I need to do?
Do I lose root when I reinstall the stock recovery to allow the OTA?
Steve
Are there any docs or usage info about the Superuser Permissions app that unrevoked3 installs? I'm not sure what to do with it.
Steve
What I don't get is the part about regaining superuser access with an update.zip after receiving the OTA. Where can I find said file? I've searched and googled and can't find it.

I have rooted, s-off-ed, removed some apps, and got the stock recovery from adrenalyne and reflashed that back. now when i try to go to recovery, i come to just a phone symbol with a red exclamation mark and the only way to reboot is to pop the battery out. is that what stock recovery looks like? or have i boofed the process at some point?

Yep, that's stock recovery. You need to load clockwork recovery, I think that's how you fix it. Someone please correct me if I'm wrong.

also, titanium downloaded busybox, what is busybox and how does it affect my ability to apply an OTA?

At the stock recovery you press vol up and power and you get a menu you where its possible to reboot, install undate.zip...ect...
From what I hear you only need the stock recovery and the stock build to get and install the official ota.
If your rooted that should be fine the ota will likely remove root but who cares with s-off!

Ok so lets see if I did this correctly. Im rooted with unrevoked forever. So I just Downloaded the pb31mg file and did a reboot into recovery via rom manager. I then applied an (update.zip) from the sd card which was the pb31mg.zip. I then reboooted. Is there anything I can check to make sure Im stock enough to recieve the ota?

[Q] Change custom rom

good day everyone, i would like to ask how to change custom rom.
i have a rooted desire hd and flahsed coredroid v2.3 but i want to try different rom like the leedroid. how do i change to another custom rom? do i just go to recovery mode -> wipe -> flash? or do i need to do other stuffs? please help me. i'm still a newbie and i still lack knowledge on android
Recovery, backup, wipe, flash done. You might need to install a gapps addon for the market. Just flash the zip after the rom.

thanks for answering, how do i apply a rom update? i mean i put the .zip file in the sd card root right? then how do i flash it?
Reboot into recovery, install zip from sd card, install custom zip, flash it. If you're upgrading within the same rom there's no need to wipe.

Can only flash roms in rom manager...

So, as the title says, I've had my incredible since september, I'm pretty sure its a slcd since it shipped with 2.2. I rooted it immediately with unrevoked forever, so I have soff, recovery installed, rom manager, set cpu, etc.
So I do know I'm rooted for sure, and I even can flash roms. But with a catch. I can only flash roms if they're downloaded and flashed from rom manager. I've tried downloading roms from xda or other forums. None have worked. Upon getting to the point of opening the package in cwm by applying either update.zip or choosing a specific one.
I'm not sure what I'm doing wrong.
I know that when I tried to use the name update.zip, it wasn't update.zip.zip I know I'm rooted with soff and can flash roms, only through rom manager so far, and overall I think I have a good idea of what I'm doing.
Obviously I'm screwing something up SOMEWHERE. so I know it's probably user error.
I'm on a snow leopard mac, and when I download roms I have to compress them to .zip, i know its a .zip for sure, but that could be the problem? And yes I'm putting all these .zips on the root of my sd. Cwm recognizes the.zips, just has trouble with them or something.
Here's what I do in cwm, go to apply .zip says opening package, then goes straight back to the cwm screen with all the options you get when you boot into recovery.
Any help or advice would be great!

Not sure if this is the problem, but when I download Roms from anywhere I don't have to compress them to a zip file, I just put them on my SD card and flash away. Have you tried simply downloading them and then flashing without compressing them?
No I've tried that before, but because its un compressed cwm doesn't like it

Is your SD Card in Fat32 format? I know if you aren't in FAT32 format the update.zip won't work - well it didn't for me anyway!
EDIT:
It's safari, somewhere/somehow when it unzips .zips something goes wrong. When I downloaded a rom using chrome it flashed perfectly.
So hopefully anyone who has a mac having this problem as well won't be as dumb as me >.>

Can someone answer a question regarding jellybean?

I installed this yesterday jb-takju.zip. I was originally on cm9 rc1. In the process I managed to wipe my entire directory, nandroid backups included. I tried to get cwm back via fastboot and was able to then flashed CWM-SuperSU-v0.89.zip to get root right after. Now besides losing all my data, I cant keep the cwm touch recovery on, it keeps going back to the default recovery screen when I try to boot into recovery from rom manager. So at this point I'm baffled, not used to not have an sd card.
How can I have avoided this? How does titanium backup work with dropbox I couldnt get that set up. Also should I be flashing a different version of JB?
I didn't loose all any data on sdcard but was losing car. I ended up using the xbigie version. That was decided,rooted....

You must mean the virtual sdcard which I dont even see in my directories.
Can anyone tell me why I keep losing cwm touch recovery at least? lol
Should I just flash a different jellybean rom .zip?

Not acceptable, I already lost all my nandroid backups so I might as well use available JBs and start fresh
You're losing your cust recovery because there is a script you need to delete that auto installs default recovery on every reboot. It should be named the same as it was in ICS when the phone first came out. I'm look for the exact name now unless someone beats me to it.
Edit: /system/recovery-from-boot.p is the file. Rename or delete. Then it should stop reloading stock recovery. Just make sure you have CWM installed already and you're good to go.

[Q] Noob help with roms?

hi there
before you tell me its in the wrong section i can't post in the development section yet, i'm a new member.
so basically, heres how it is: i have an xperia play r800i(unlocked UK version) which in october i flashed free xperia kernel onto and cyanogenmod 9.1. i have now decided that i want xdark 4.0.3 on it because the wifi stopped working on cyanogenmod and it has no support for touchpads. however, i dont know if it is as simple as just going into CWM and flashing the .zip from there.
can i do that? or do i need to flash something like doomkernel? and can i flash that the same way i flashed FXP?
i am quite a noob when it comes to this, so any help is appreciated.
it is rooted and the bootloader was unlocked the official way.
thanks
Back up everything with Titanium or something similar. Then place the XDark zip file onto the root of the SD card.
Then, with Flashtool:
1) Flash R800i_4.0.2.A.0.62_phoenixvendor.ftf found here: http://forum.xda-developers.com/showthread.php?t=2184897
2) Flash LuPus ICS: http://forum.xda-developers.com/showthread.php?t=1804003
Once that's done, boot the phone and enter recovery (pressing back when LuPuS flash screen appears and phone vibrates), clear the cache and dalvik cache partitions, then install the XDark ROM. When that's all done, reboot and all should be done.
XDark seems to be suspended for now though, might be better to go for something that's still currently being supported?
thank you for your swift response, i will be doing that later.
Do both a titanium back up and a nandroid just to be safe also do the normal whipes
