Why did I lose root? Please help!

First off I would like to thank everyone on this amazing site for all the advice, guides and tutorials.
I unlocked my nexus bootloader and flashed a couple different roms. I really like the rom manager so I've used that to download roms and then flash them using that app.
When I downloaded the stock version of 91and flashed it, the phone no longer seemed to have root or clockwork recovery but my bootloader was still unlocked. When I downloaded rom manager, it could not get super user permissions, this being useless in flashing a backup or new rom. So I used universal one click root to gain root access and then rom manager was able to flash a backup.
I know this may be a dumb question but hope someone could explain to me why I needed to re-root and why I lost clockwork recovery...?
Thanks for the help in advance.

Right theres your problem. stock roms dont have root built in you have to root them again. unless you download a prerooted stock rom. hope this helps.

Yep this seems to be your problem. If you're wanting stock with the basic add-ons then the first link in this thread is your answer: Link.

Thanks very much. That does make sense. I thought unlocked bootloader meant I was rooted regardless of rom! I'm in way over my head lol. Looking forward to learning more...thanks for the new rom link as well

The advantage of unlocking your bootloader means you can flash a custom recovery from Fastboot mode, without having to "root" the ROM. Next time this happens you can just boot into fastboot and flash clockwork from there like this:
fastboot flash recovery PATHTO\RECOVERYFILENAME.img
so say you download clockwork and save it to c:\sdk\fastboot named recovery.img from a command prompt you enter the following
cd \sdk\fastboot
fastboot flash recovery recovery.img
once it is done flashing you can do this
fastboot reboot recovery
and that should take you into clockwork where you can flash your favorite ROM (or restore a backup).

Thanks for the help. I will be sure to try that method out next time. Very helpful.

[Q] flashing custom recovery - frustrated!

Hi,
Upgraded to 2.3.3 and lost root.
Bored of mucking about with oneclick etc, I unlocked the bootloader. Easy(ish), cool!
Trying to flash amon ra with fastboot, everything goes well (appears as though it's flashed). But when I re-boot, it isn't there!
Padlock showing - so bootloader unlocked.
Nexus drivers installed, device showing with "fastboot devices".
Trying to flash amon ra 2.2.1.
Any suggestions?
Ta!
Andy

When you boot a stock rom it wipes custom recoverys and puts the stock one back.
Use the search feature on the forum.

Thanks for your reply.
I've spent (literally) all day searching the forum (I'm in the uk - so hours and hours). There's so much, and some of it contradictory.
Ok, so I can't put a rom on without a custom recovery, but I can't put a custom recovery on because the stock rom wipes it?
I don't actually want a custom rom, simply a rooted stock phone. Which I have had previously.
Cheers! (driven to booze!)

Yes, that's what I've been doing. There's a mistake in that part of the faq:
Faq states at the end "reboot recovery"
Should be "reboot-bootloader"
That works, but as soon as I then reboot into 2.3.3 - it wipes the custom recovery (which is why I'm in the q + a).
The other problem I'm having is that my phone doesn't appear rooted from within the o/s (apps that require root don't work), but the padlock is there ans the bootloader is unlocked. I can install su and busybox installer from the market, but neither work.
Back to the beer!
Andy

I can't explain all in detail while on my phone.
Do this. Grab a preroooted stock rom from the dev section and put it on SD card.
Boot into fastboot and flash the custom recovery.
Then load up that recovery without booting up the os.
Flash the rom you downloaded.
There are other ways to fix your issue but this is probably the simplest for you.

Thanks, that makes sense - and I agree with your statement above (simplest for me)!
I had (mistakenly) thought that unlocking the bootloader, then installing busybox and su from the market gave me a rooted phone.
I'll give it a go, when my wife regains her patience ;-)

Damn, you're right. The guide is missing the part of removing 2 files that the other guides have. I'll try adding that.

Guide fixed. I've uploaded and linked the file that removes the stock recovery restoring files from the stock ROM.
You can repeat the guide and include the new part - it should prevent stock recovery from being restored on reboot.
Please try and write your feedback.

cheers! i've done what was suggested tho', and its worked a treat.
thanks again.

subscriber lock

hello.. my xperia x8 was originally subscriber locked and was unlocked by a technician (i ddnt know how and what he did) while being retained on stock and unrooted.
now the question is, will the unlock remain once i flash a custom rom such as ginger dx?
if not, how can i disable the subscriber lock?
thanks in advance for your replies..

Not at all....your bootloder remains unlocked always if it is done properly.

thank you for replying.. i hav more questns tho..
youre saying that the subscriber lock is with the bootloader?
would you consider using x8 toolbox in rooting the phone as proper?

Yes....you probably have unlocked bootloader.....would you minfd to look under the battery for a date number?
turn off phone
take out battery
look at the BACK SIDE of PHONE(not battery)
find something like 11W30 or 10W30 or 12W30...
Write down the number
Why would you want to use toolbox??
PRESS THANKS if someone helped,don't just say thanks

its 11w35. good thing the techncian ddnt brick it.
i want to install a custom rom and root this thats why i might need the toolbox, am i right?

Didn't brick during unlock progress? Sooo lucky!!!
-you can install flash-tools app (latest may not support x8) & download a custom kernel then flash kernel ... (read guides)
Then flash roms from recovery

can you ask your technician what method did he used to unlock it?
Don't install toolbox,download Flashtool
With Flashtool you can:
Root
Flash
Install apps
Clean
Install kernel
Install recovery
And for installing custom rom :
Root via flashtool
install recovery via flashtool
Put custom ROM .ZIP file on sd card
Flash custom kernel
go in recovery via phone(by pressing BACK button)
flash rom
tadaaa...you're done

what i remember is that the techncian used "credits" in unlocking but i'll ask him..
ok. flashtool it is.. im just concerned on losing the subscriber unlock and bricking the phone when installing custom kernels and roms..

You can download official CWM recovery. Search here: http://www.clockworkmod.com/rommanager for LG Optimus 4X HD.
Then you can install with terminal, fastboot or sth else - I don't remeber well.
Then the fun starts. (On XDA look for ROMs and kernels)
And read the instructions carefully.

Unlock ur bootloader 1st!

Agreed but after reading posts on how to install, it requires an unlocked bootloader. is it necessary or can it be done without unlocking bootloader ?

It can be done without unlocked bootloader, but then you will be unable to install custom ROMs. So if you're on stock JB, unlock bootloader if you want (warrany will be woid).

That's not hard first you must root tour phone then install rom manager choose tour phone from it flash recovery reboot in it then flash zip file that's all

I have rooted my phone.. so, what your trying to say is that i can go the regular way, like install clockwordmod recovery and then flash a custom rom without unlocking bootloader ?

First you need to unlock your bootloader after that you can Install CWM or TWRP.
After doing all this you can Instal CM or any other ROM.
If you try to install the CWM or TWRP without unlocking the bootloader you will get the boot signature error and you won't be able to boot into recovery (please correct me if I am wrong.)
Don't Forget to make nondorid backup before you try installing any ROM in case you know what I mean
and next time post it in Q & A thread please..
Have fun mate.

yes you will get an boot image signature if you install cwm or twrp with locked bootloader
the only way to flash a custom rom on an locked bootloader is to adjust the rom to the stock kernel and device and the flash it via a bootstrap( like dexter did it)
but nobody is going to do it if you have tje possibility to unlock your BL seems that you have to stay at stock rom if you don't have the know how how to do it

It's not a trick, but it is pointless for a high end device as all it will do is increase lag and kill the SD Card due to the high amount of writes.

You really haven't given much informaton to go on. Basics with any help request;-
What are you trying to achieve?
What version are you running?
What ROM were you on before?
Rooted?
Bootloader locked or unlocked?
What recovery have you installed?
EXACT error message - this is the single most important detail!!
There are plenty of guides around if you are trying to get from 'Stock' to CM10.1;-
Upgrade to 'Stock' JB first
Root
Unlock bootloader
Install CWM (v6.0.3.1)
Install CM from zip
Install gApps from zip
.....
Profit

Rooted yes.
My device is SEA, not sure if I unlocked bootloader...(might be the problem)
The recovery i stated on my question.
I now can only hope lg support tool can help me out.
Because I might forgot bootloader and my device is already wiped out clean(so i cant even return to stock because the whole device is empty).

Figured out how to enter download mode... haha

Highlighted in red for a very good reason. You'll need to reflash your stock v10e first, yet again there are guides on how to do this. Once you have the phone back up and running on v10e then read carefully and make sure you understand all the steps before trying again
