Root [GUIDE] FroYo 2.2.1 for Root Users! (Updated 3/3/2011 at 3:40 pm EST - NOW EASIER THAN EVER!)

Your best bet at this point is to visit the AllyIRC and get help there in real time. I would not have succeeded either without their help. Sometimes it gets a little hectic in there but patience and politeness go a long way. :) Most of the folks who hang out there have already done this, including the devs themselves who made the rom and wrote the instructions. They are usually very helpful. If you search the Ally thread for a post by member Dots and 'AllyIRC' you can find a thread with a link to get you to the AllyIRC easily.

I am using the LG Ally and everything was fine until part 27 and 28. When I try to reboot my phone it keeps going back and forth between the LG screen and the Verizon screen. All I am able to do is pull up the recovery screen.

You can get Froyo now without having to execute step 27, as it is being pushed OTA to everyone. Just do one more CHECKIN dialing and you should get a notification at the top of the screen asking if you want to download it. IIRC the file is 52.3MB. Thanks to Dots for telling me about this.

A silly question that may have been asked already. If my phone shipped with V6 and I still have fastboot, do I need to downgrade to v6? Should I just do it and not bother with other methods?

Can I start at step 25 and flash stock recovery then take the OTA? Thanks in advance.

Just curious if anyone could answer this for me? Still hesitant to make the jump, just wondering if someone could let me know.

I can pair via Bluetooth with 2 other devices (both are Windows Mobile) but I cannot actually connect with them. I did "once" and was able to see files on the first device. But I can't make it happen a second time.

Is this what you meant by "not working" or are you unable to do anything at all with Bluetooth? I am not very familiar with it.

I cant pair my hands free headset. Phone searches for it but doesn't find anything. I am running Velocity 1.0 so not sure if that affects things.

About the only thing I can offer is to check and make sure your HF headset uses a Bluetooth profile which is supported by the Ally. If not, that would prevent you from pairing.

I don't know if you already read this but the Ally user manual has a section on how to pair and connect with Bluetooth, in case you had not seen that yet. One thing easily missed is remembering to set your device to "discoverable" when doing the initial pairing setup.

I ALMOST got all the way through this guide, after having probs with the LGMU and having to do the "[GUIDE][LGNPST] Alternate v6 Restore Method" posted by Death2All.

On the LAST STEP (#34), here is what my phone displays after I "select "Flash zip menu" in recovery and choose "su-2.3.6.1-ef-signed.zip"


Finding...
Opening...
Verifying...
E:Wrong digest :
META-INF/com/google/android/updater-script
E:verification failed

Installation aborted

Does that mean I have a corrupted copy of su-2.3.6.1-ef-signed.zip?
Should I try to re-download the .zip and put it on my sd card (making sure to check the md5 hash)?

Thank you for all the help I've received thus far and I look forward to one (or a few) more kind soul(s) to get me over the hump! Then, helllloooo Velocity 1.0!

I figured it out! I was being dumb and didn't do a step on headset. Blue-tooth works!

Me too, im getting the same error,
E: Wrong digest:
META-INF/com/google/android/updater-script
E: verification failed

Installation aborted.

The zip file was in the right place because it found it, its not liking the updater-script.

Any suggestions?


for some reason it failed again and when I went back and click on toggle verification, it said verification is disabled so I went to flash sd again and selected the zip file it worked! not sure why but it did.

Question. If i upgraded an old ally that had v6 on an upgraded through tridents guide to get 2.2 an root, but had to use the one of the quick root apps to get root, did i retain fastboot since i came from an older v6 version of software?

Try booting into Bootloader to find out. I forget the key combo to boot into the bootloader, but it can also be done through QuickBoot. If you see the blue fastboot screen after rebooting into bootloader, it would be my understanding that you still have fastboot.

If your talking about SuperOneClick yes, it won't wipe out fastboot or your custom recovery.

(OK, I guess I posted to the wrong thread earlier, sorry.:thinking:) Tried some failed steps in other guides but finally this seems to be the one I want. Some folks kind of asked this question, but I didn't see the answer.

I have installed the OTA 2.2.1 and have SW Version VS740ZVD. Can I start Trident's instructions at step #29? Or do I have to downgrade and then upgrade again to get root?

Thanks all.

Lol, yes I hear that. Thankfully I have an understanding spouse that allows me to do these things to his phone ;) but a barely muttered 'uh-oh' on my part still sends his alarm bells ringing.
