Lock and Unlock - Xoom Q&A, Help & Troubleshooting

Does anyone have a good link for the one click lock and unlock for our tablet. I cant seem to reflash to lock mine back> I keep getting ADB errors even though I know I have the bridge installed correctly. I just want to take mine back to stock the fastest and easiest way.
Figured it out

Recovery dead?

I have upgraded to 4.0.3 and its really slow and bugy, so I desided to downgrade, but this is what happens when I try to go into recovery, please help.
Phone is all stock, not rooted or anything...

Yes, this is normal. Your phone is an i9023, the backlight doesn't turn on with new recovery, you can see it if you use a strong torch/lamp at the correct angle, and yes it is all there and functioning (just no backlight).
I believe recovery will give you an error if you try and downgrade though. You'll need to root/unlock bootloader and use CWM before you can do that. You can happily lock the bootloader afterward.
Also, you might be happier with ICS if you do a factory reset, and maybe even reflash ICS. This can solve some problems.
Thank you very much Harbb, any suggestions which way to root is the best and easiest for Nexus S?

I'd go the bootloader method. This gives you full access to the system which will allow you to throw in the su command in /system/bin, or just allows you to install and backup any rom you'd like. Only thing is it is "obviously" unlocked and wipes EVERYTHING but the OS (that is, sdcard and ALL personal data and settings).
Of course you can relock it any time you want though, for warranty purposes. Easiest and most thorough walkthrough (from my limited scouring) is here. Has a video too
Just note, for ICS you want the latest superuser zip, not the one provided.
Thanks guys, will try something now.

Should I root and unlock

I just got this phone and debating if I should root and unlock this phone. I'm a big fan of CM. I traded a friend for this phone. I used to have a gs5 and touchwiz was driving me crazy and that it could not be unlocked. This phone is way better. I have been rooting and unlocking since the days of the htc eris. I'll never buy another Samsung phone again. Sorry for the dumb post.
So do you have a question? Or what's the point behind the post
Yes, you should root and unlock. I have flashed more than a few roms on this pbone, but I have been on stock rooted for a couple months now. Mostly because it has the least amount of issues and most consistent performance. I got it all tweaked up though. IMO HTC did a great job on the stock ROM but to each there own.
And another big plus is that you can easily unroot and relock your phone back to 100% stock state (thankfully we have all the most recent stock ROM ruu's). So really as long as you know what your doing which it sounds like you do, you can only gain by rooting/s-off
No, wait a few weeks first so you know the phone works. You don't want to be those guys that spam issues in rom threads only to find out it's your phone and not the rom.
A rule of thumb I always follow is make sure it runs properly before you start modding. (Cars, phones, computers, etc.)
the real question is why wouldn't you unlock an S-OFF - full control over YOUR device for only $25 AND you can always go back to S-ON. :good:
I tried to unlock the boot loader through HTC Dev with no luck. My boot loader says ***software status*** Modified
***Locked**
He was running the phone on T-Mobile. I was wondering if he had it flashed to T-Mobile to work. Any Ideas!!
Never mind I just used sunshine apk and worked. Thank god
Bootloader still says modified. Only getting temp root, but s off

To get permanent root you will need to install a custom recovery and flash the supersu.zip and that will get you full root. You can then get rid of the temp root by uninstalling the apk
I figured it out. Its been awhile since I rooted and s-off. I already fixed the bootloader saying modified. Had to connect it to htcsync and do a repair. Thanks guys. I'm enjoying cm again.

lost recovery

I rooted my stylo last month and shortly after I flashed a twrp recovery in which I thought it was for my ls770. Well after I did that I got that error 1003 thing when I try to boot into recovery. So I now can't boot into recovery So I found a factory recovery file and flashed it also and I still can't boot into recovery. Can someone help please and thanks..
What version of Android? I did the same thing and luckily I had backed up a recovery with Flashify. I can see if I still have the backup. The recovery was for 5.1.1 ZV5
The one I found I think was for 5.0 but I'm on 5.1.1. That would be great @mabry

Do you have the stock recovery or what cause I need it asap
My bad bro. When I updated to Marshmallow I formatted my external SD in hope of the new storage feature. I lost it. I am sure 6th Hokage, or Dominick might have one laying around. They the main devs on the Boost Stylo.
did you ever get the stock recovery, I have the same problem...

Add me to the list. I can't get anything but secure boot error 1003.
Me too..
Add me as well....
Rooted and went to install twrp..secure boot error 1003.
Anybody get any news on this?
The TWRP that is available out there right now with all the tutorials isnt for our devices (LS770). Theres not much going on with our devices because of the locked bootloader that lg seems to know nothing about; let alone any support for this devices alongside marshmallow. My goal is to port TWRP to our phones and find a backdoor in but im caught up in a bunch of different projects right now and juggling it with work. Plus ive gotta learn how to build these things. If anybody could tell me anything about our phone that i cant figure out thatd be wonderful. Ill try to get the recovery image posted on my drive when i go on my computer next.
Lg lls770
So I've read even just using King root it will lock up your phone, i had done that with my other lg ls770 and tried installing the twrp recovery. Any ideas if i will run into the same problem just using King root? And how would i go about making a back up of my stock recovery?
The ls770 has a locked bootloader. You can't just put any twrp recovery on it. You may be able to use kingroot temp, but I bricked twice using it, and can't offer any advice. If you have read enough of the ls770 brick stories including mine, you'll see there is no real pattern to bricking with kingroot. I successfully used it and restarted and re temp rooted for days, changing build.prop uninstalling google apps, then WHAM, brick out of thin air. Some were bricking straight away after kingroot with only restarting. If you do use kingroot to temp root I hope you'll report back and tell us how it is going, Thanks
So any idea if checking the oem unlock box in developer options and then going to fastboot/download mode would unlock the bootloader? I'm not very advanced with tinkering with android but i can go about the basics i guess

The oem unlock will not unlock the bootloader.The bootloader is locked by Boost/sprint/virgin. It's probably not going to be unlocked. The only LG's I know that have unlocked bootloader are Tmobile/metropcs. I hope kingroot gets this worked out as we know they have no future without being able to root phones. I made a post on the kingroot page here at XDA asking about what they might do now with marshmallow. I haven't heard from the main @Kingxteam but I keep hearing they are working on it

Damn I screwed up. What's needed to fix it?

I noticed after taking one of the lineage updates I lost root. I tried to reroot with odin and managed to pork my phone quite good. It took me until about now to get it rooted, unlocked and finally TWRP loaded. Recovery was fighting me the most. Refused to install in odin. I finally got a working rom on it so it would boot. Used casual to root and unlock but TWRP failed in that as well. I finally tried a TWRP app (not the official one, I couldn't get that to work) and I may have my phone back now. Waiting to see if my backup is going to work. Welp, it didn't like the restore and I got the ! triangle saying go back to verizon.
While I was looking through my drives I noticed I have a ton of files but don't know exactly what they are. I've had this phone since I pre-ordered it so at one time the files were valid. What files exactly do I need to totally unpork a phone? I have odin 3.07, the VRALEC bootchain, the VRALF one but odin says it's invalid, and a file called combination_I535VRALG1_I535VZWALG1_743127_REV09_user_low_ship. Using them I can get my phone back to seemingly stock.
Is there a better way? Or at least a way to totally start from scratch and hopefully get lineage back on? I know not to take any of the OTAs since they will relock the bootloader. I don't like that it seemed that it was going to automatically install the update but I'll just keep the phone off until I can sort it. I also have a bunch of other files across 3 computers so if there is a file that's needed but isn't posted somewhere there is a chance I might have it already.
I've been searching for the past day and I've found tons of info but some things don't work and some only kinda work. Any help would be much appreciated.
More info: I am on 4.04 so the bootloader should not be locked. The phone is beat up and the USB connector is wonky. Only a few cables will work and I have to make sure it doesn't move or it will disconnect. It does mention that the secureboot is enabled in download.
I've had it rooted, running a stockish rom and managed to get TWRP on it but when I went to restore my lineage backup, it all went to hell.
So I'm now having issues with the bootloader. ON the download screen it says custom binary download yes (5 counts), Current binary samsung official, system status official and secureboot enable. Pretty sure that means casual didn't work. I have root but not bootloader. Is there another option than casual? I've seen ez unlock 1.2 mentioned but the links are dead.
Why am I remembering flashing something in stock recovery? It's been a long, long time since I've gone back this far. I feel like I'm close since I saw the unlocked screen last night but restoring screwed that all up.
This doesn't make sense. I installed TWRP but it still says the same as above leading me to think my bootloader is not unlocked. I don't get the unlocked boot screen either.
How can I install TWRP with a locked bootloader?
Well it's obious that I can get root, install TWRP but for some reason casual will not unlock the bootloader. I can't seem to find the old thread nor any files to just unlock the bootloader. I know somehow I did it last night as I saw the unlocked screen it's just damned if I can do it now. It must have been another file I had at home but don't have here on the laptop.
It's damn frustrating since this time yesterday I had a working phone running nougat and my dumb ass broke it.
I know this forum is a bit dead, as expected for a 5 year old phone but hopefully someone will see this and have some sage like advice.
Turns out It takes almost a week and a mixture of 3-4 guides here. Some Odin, some Casual, some TWRP flashing and luck. FInally I'm back to where I was before I hit the wrong button.

frp storage location

does anyone happen to know where frp data is stored on the phone? i bought a used one and the previous owner didnt reset properly so im trying to get rid of this idiotic stupidity before i give up and refund it. he didnt relock it when he sold it so i was able to install twrp and have basically full control of the phone, i just need to know where everything is stored so i can get rid of it. id like to just clear it out rather than doing that 50 step convoluted bypass because i dont want any problems in the future.
Probably should have put a question mark on the title to keep it from looking like a solution. Whoops lol.
Either way I've found a bypass, literally just deleting the setup apk. I've been using my new phone all day rebooting and flashing and installing, and I haven't had one single problem. Of course this requires root or twrp or some other method of rw /system access, but if you can somehow get into settings during setup to enable oem unlocking so you can unlock the bootloader and flash twrp, then you're golden. When I get home I'm going to investigate if this is temporary or permanent (as in do you need to remove setup.apk every reset or does adding your account overwrite ownership).
