Root wirelessly because I've lost my cwm recovery

Can I root wirelessesly? I ask because my phone is fc ing on a lot of apps and after I flashed this last rom I lost my recovery...? It wont let me boot into recovery to flash a backup so I was hoping to root , install rom manager, and flash cwm recovery and do a full wipe restore.
If there are any other suggestions im all ears because im out of town until Friday morning and can't install anything on my work cpu or I would install fastboot etc.

you shouldn't have to install anything on the computer, you would only need to download the files
What files exactly and how do I install it without being able to enter android recovery ?

Can you getvin fastboot? If so, do command

That should do the trick

I can get into fastboot on the phone but how do I get fastboot on the cpu without installing it, or am I missing something?

Just download adb with fastboot from google if you don't already have it, restart your phone into fastboot, open cmd prompt from computer and follow commands to install romracers recovery in his thread under development. This only works if your unlocked btw. http://forum.xda-developers.com/showthread.php?t=1204500

Make a live Linux CD/flash drive and boot to that if it allows you to. Then try the Linux versions of adb/fastboot.

I'll see if I can figure that out because Im not up to date on linux and how it works... As the days go my system seems to be getting worse.
Sent from my MB860 using XDA App
So I have tried everything to no avail. It seems like the phone is getting worse day by day...
I wish I could root from the phone not tethered some how so that I could install rom mgr and flash cwm recovery and access my backups, or be able to fastboot somehow, or find some way to install a recovery without tethering to access my backups!!
Im worried my phone will explode over night...lol
I don't understand how you lost your recovery without root... and you would have to be unlocked to write to the recovery partition, yes?
Find a windows computer that you have admin rights too, download the Motorola Drivers and Fastboot.
Presuming you are unlocked:
Boot your phone to Fastboot mode by Powering off the device; pressing the power button and depress hold the down volume key until a little words say RSD something; then use the down volume key to navigate to Fastboot; then press the up volume key.
Then connect the device do the computer and reference this thread to install a new CWM recovery.

This last time I flashed, something must have been left inside the phone that the current rom did not like.
The rom itself is supposed to be rooted and unlocked the phone itself is still unlocked, but superuser permissions won't be granted to any application and when I try to enter android recovery it seems like it's going to work but all it does is boot the phone back up without the radio working.
I have ben trying to find a cpu for 3 days now so I can do just that. I'll be home tomorrow and should be all good.

And what does that tell you?
To me it says you can't use something before you have it installed.
If you don't have your system PATH pointed to the fastboot executable, then you must run the commands from the folder where you have the fastboot file saved.

how do I do that? I couldn't figure out what to do after getting on the fastboot screen on my phone. Sorry I'm a noob.
When you download the zip file extract it. Next take out the battery and make sure device manager is up.
Plug in the phone without the battery. This is tricky... You need to double click on the new device and install the OMAP fastboot drivers located inside the extracted folder.
Now you know how to enter fastboot! Take out the battery, run start, plug in the phone when prompted, then flash ICS u and x.

When i go into recover the "teamwin" logo comes on, the it promps me to to a menu which seems as if it would work with touch screen... when it says install it will not allow enter any option its almost as if its frozen and the touch screen does not work.
After a lot of searching i think i figured out what it was you were trying to say to me. I did what you said using TWRP the picture shows what happened after i opened the cmd window and typed the command. TWRP freezes up when i go into recovery. Am i doing something wrong?
Replace nameofrecovery.img with the actual name of the file, more info here
http://forum.xda-developers.com/showthread.php?t=2277112
You may have the wrong twrp image installed to your phone, I can think of a good reason why it freezes on you. So when in recovery you can not press any option? If this is the case I would look for a new copy of twrp specific to your device, check md5sum, then flash it with fastboot

Yes it gets stuck in recovery... i cannot use the touchscreen at all...
i downloaded the newest twrp copy... i downloaded md5sum and i have no idea how to use that even after looking it up and searching through youtube. i have the new ".img" file on hand... i just need to find out how to erase the old one in order to install the new one and see if it works
here is the CMD screen
this is what happens when i open "minimal adb and fastboot" and type in the commands you sent me... the top one that says failed, is when the phone is in the fastboot usb screen... when it says waiting for device... the phone is just turned on
Being you are s-on (can confirm if you write down all info on phone when in bootloader mode) you probably don't have permission to erase recovery but you should be able to just overwrite it, so just
fastboot flash recovery twrporwhatever.img
Also I believe there is a way to gain s-off with your phone, once you get all this down than I suggest doing that but first get the proper recovery
Oh and there are many ways to check md5sum (just Google for one if the one I linked you isn't working) this just makes sure you had a good download of a file, a good idea to do it but not need

Hard bricked P760

Hi guys, after 10 hours of trying to get my P760 to life I finally, as a last resort, decided to open this threadh. Heres the deal, my friend gave me his P760 which was stuck at the boot logo, I firstly tried to fix it with LG mobile support tool but it got stuck at 15% after countless tries. Then I tried fixing it with Lg flash tool but it also gave me some errors "omap factory download fail lg p760". After that I couldnt access S/W mode anymore nor did the phone turn on, only black screen. When I connect it to my pc it just makes sounds of new device connected/disconnected. I tried this fastboot method http://forum.xda-developers.com/showthread.php?t=2292828 but couldnt make it work. Is the phone completely dead or is there anything more I can try? Any help is appreciated, thank you very much.
What was done to brick it in the first place?
Sent from my KYOCERA-C6745 using Tapatalk
I am not sure, my friend brought it to me and he didnt know the reason. Anyway I managed to get into fastboot on another computer and i tried to flash x loader and uboot with the bulit in options and i get the following error "FAILED (remote partition doesnt exist). What can I do next? Thank you for the reply.
EDIT I have tried to get the phone in S/W mode using this guide http://forum.xda-developers.com/showpost.php?p=44325657&postcount=4 but I couldnt do it.
I am sure I have to flash something in fastboot so it would be great if someone could point me to exactly what. Thanks again.
EDIT 2 I tried to flash xloader and u boot from post #7 http://forum.xda-developers.com/showthread.php?t=2242444 and it gave me the remote partition error failed again. Is the phone "officially" dead?
My experience with this phone is that it is basically unbrickable, at least software wise, thanks to omap4boot. Fastboot is basically telling you the partition you specified doesn't exist. Check you are using the correct syntax. It should be fastboot flash u-boot u-boot.img and fastboot flash x-loader x-loader.img (I am assuming the files are named u-boot.img and x-loader.img).
Another possibility is that the partition table of the phone somehow got corrupted. In my opinion this is very unlikely, but it could happen if the phone is disconnected while flashing the GTP table with LGFlashTool. Let's hope that's not the case.
Good luck.
@EdwinMoq thanks for the reply. I checked and I was using the correct syntax altough the files were named p1 and p2 both in bin format so I typed fastboot flash u-boot p1.bin and p2.bin respectively. Ive just noticed that they are from ICS and I am not sure what android version was installed prior to the brick. Can you point me where to find the JB files so I can try them if it makes any difference.

I don't think the u and x boot version makes any difference. The fastboot script here comes with with the files for both p760 and p769. Or you can ask a p760 user with the jb boot to dump them and post it here.

Well using that script was the first thing I did after I couldn access S/W mode and I got the partition error, I tried both ICS and JB. Well it would be great if someone could dump their JB boot so I can try that, if it doesnt work I guess Ill throw the phone away

I'm seeing you using lelus method to fastboot...
1) Be sure you are in fastboot whith this command: fastboot devices
2) if the l9 is still in lg logo, just flash a recovery img into boot and recovery partition:
a) fastboot flash boot recovery.img
b) fastboot flash recovery recovery.img​3)reboot the device, it must enter in recovery mode by force.
4) once in recovery just flash a custom rom as you wish
Yes i am using lelus method and I see the device when I enter fastboot devices, the phone wont turn so there is no lg logo and I can not enter S/W mode. Where can I find the recovery.img and boot.img ?
EDIT Okay I tried this too http://forum.xda-developers.com/showthread.php?t=2585161 but when I issue the erase command it just gives me the remote partition error again. The chances that this is a hardware issue are pretty big.

A few tricks that might help:
-After a failed attempt to enter D/L mode via the volume key, force hard reset. Then switch on phone for an extra time and perform the hard reset again. This really makes a difference.
-If after unbricking the phone with a stock rom the puny LG recovery dialog resides on screen, perform the stock rom installation for a second time, phone should perform a normal boot then. Otherwise there's trouble with rooting and TWRP installation later.
-Fastboot still does not work for me(all?) in Win10, as it didn't in Win8.1,but did in Win7.
The only method to go on seems to root stock rom with Kango Root or a similar tool, then install Twrp, with Rashr or flashify.

Elsewhere you must need a technician with a box like octopus box to recompone ESD partitions of the L9 phone
Hard reset is 10s power.
Such a swap of recovery and kernel could have happened after unbricking the phone, when the key combo for fastboot produces the LG recovery. That's why I flash stock twice, then it's right again & ready to root, install TWRP etc.
Thanks for the help guys, I tried everything possible...I think I did, but the phone just wouldnt unbrick so it is going into parts. Thanks again.

Srsly?
recovery partition image on boot?
Probably true. That would explain the strange behaviour of the key combos during boot, after unbricking the phone for the first time. The recovery has replaced the kernel, but the phone can still boot. Strange. Fastboot is unavailable, and the key combo for the recovery shows the "dead droid" and performs a factory reset.

Yes... is an effective method to boot by forced on TWRP or other recovery and then proceed to format all partitions and flash any rom consecutively. After flashing any rom the boot partition is rewrited by the boot.img of the rom.
I did this before on my own L9 for repair and other friends devices. Is totally safe
By the way, I'm not in warn
