Hi guys, i've seen that custom roms are in an early state of developement so i'm thinking of rooting my OB just to remove some useless default applications. Now the questions:
If an official update is released by LG (gingerbread hopefully), do i have to unroot the phone before i upgrade it by pc-suite?
if yes, how could i unroot the phone?
Thank you so much!

I have a noob question guys. I root my phone and delete some default apps like Car Home, News, Finance. Now Car Home, News etc is deleted it is possible to UNROOT my phone? Do you think if i UNROOT my phone it can cause a problem/bug? I try to restore some of my default apps using titanium backup but after 30 mins of waiting nothing happens. Still i can't restore it.
of course you can't restore stock apps if you have deleted sources apk without backups. So you must find stock apps, copy them to /system/app (root needed) then installing them

I do backup before i delete the apps using titanium backup, But the problem is when i try to restore the stock/default apps after 30 mins nothing happens. I check my sd card in titanium folder and the backup is still there. I also try to delete some apps that can be found in the market like angrybird etc then i try to restore it and it works! So I'm just wondering, when it comes to stock/default apps why l can't restore them even though i have a backup.

you may haven't write permission. Are you fully rooted ?
The original question from gabrieles84 is still valid in my opinion. As radkor indicated I searched the forum, but there are many methods and can't find a conclusive answer.
I was wondering the same thing. There are a number of methods of upgrading the firmware. Which is safe with a rooted phone?
1. FOTA (from settings menu): in this thread (http://forum.xda-developers.com/showthread.php?t=1204903&highlight=unroot+before+upgrade) it is indicated the root was the cause of the bricking. So it is safe to update this way with a rooted phone? Or is this dependant on the firmware and recovery? (my firmware is V10A no CWM)
2. LGMobileupdater (B2C). Is this safe with rooted phone? In my case it tells me there is a new firmware, but I'm not sure if it is safe to upgrade since I rooted with SOC 1.95, unrooting is not that simple in that case.
This will not work in this case, factory reset does not unroot, http://forum.xda-developers.com/showpost.php?p=16519995&postcount=19
3. KDZ. This post indicates it is not nessecary to unroot: http://forum.xda-developers.com/showpost.php?p=16522163&postcount=23
(I'm not mentioning the R&D Test Tool in this list, since that is only needed in case of a brick right?)
Thanks in advance!
1. FOTA - isn't safe with root - I bricked my phone with that
2. Safe
3. Safe
R&D Test Tool method is the same that KDZU but with a final factory reset.
Then, it's the way to flash devices that doesn't run well after reflash because of data inside the phone in conflict with new flash.
But, IMHO, I¡ll recommend ALLWAYS use R&D Test Tool method instead KDZU because IT'S THE SAME but additionally makes a hard reset, that is what usually we have to make after a KDZU reflash.
Regards.
Just to confirm: yesterday evening I updated my phone with LGUpdater (B2C) from V10A to V10E without removing root. No problems and now running newest fw.
Thanks guys!
So in my attempts to undo unbrick my bionic i was able to get back on the path and got into a rooted 901 version YEAH.
Problem is my webtop version is WT 1.3.0-105_DBN-1 which is not the current version. Does anyone have a way to get an updated grfs version onto the phone or a process that works coming from 901?
The problem as I see it, is that you aren't really on 5.9.901 because you couldnt have updated with the leaked update.zip without having all of the signed components from 5.5.893 including the webtop partition. You must be using a ROM that updated only your system and nothing else.
The solution is to use the full 5.5.893 xml.zip released recently and flash it with RSD Lite and it will put you back on the path with all the stock images.
If you wanted to only flash the grfs.img from that file then you need to use the moto-fastboot.exe instead of the fastboot.exe because it is modified to handle larger than 256MB images.
It is difficult to tell where you really are with all of your firmware components and whether just flashing the webtop will do you any good. That is why i recommend the full xml.zip and RSD Lite.
This is the method that a technician would use to fix a returned device to stock and is what the file is designed to do. Its like an SBF file but uses the fastboot interface instead of the old flash interface.
We have all the tools we need to recover virtually all problem flashes at this point, and its up to everyone who is modding these devices to understand the options before you flash any ROMs so you dont find yourself returning a device that you destroyed to VZW for warranty replacement, a practice all to common unfortunately.
Hi Everyone,
I bought a used phone, verizon droid 3 with the XT883 radio flashed on it, and have working safestrap 3.05. Currently I am able to use CDMA OMH, but without data. I have tried multiple options including flashing the newer version of the radio, as well as pppd-ril.options editing but it does not work. CDMA apn settings are disabled. I have also made changes to build.prop without any results. Anything else I can try?
One of my options is to flash the chinese ROM as it supports CDMA apn settings. I am not sure I can use RSD lite in one of the ROM slots.Can I select one of the ROM slots as active and flash the xt883 files on it? I think it will write to the stock ROM partition itself? Any help on how to go about it?
EDIT:
So I uninstalled safestrap and tried to flash the XT883 ROM(57.1.60) using RSD lite as described, but the following files showed an error in flashing and the phone bricked 1) Cdt.bin 2) Recovery 3) boot. I tried to flash by editing the xml file and skipping these files, but the phone showed a black screen on normal boot.
I tried to recover using psouza's rar file, but even there recovery and boot failed to flash. The phone is working though, and I am able to retain former functionality using motofail and flashing the XT 883 Radio again. Can someone suggest me a solution by which I can install the XT883 ROM and/or be able to access CDMA APN settings? Currently my fastboot suggests that my system is on .890 version, though the settings>about phone suggest I am on XT883 (possibly because of the radio)

I have same problem plz if have any idea about it plz share
Thanks
ive had the phone since at&t had it on display. rooted it and had various roms for the last couple years and never had any serious issues. last night i flashed jellycream v2 and then did a factory reset inside the rom. the phone prompted that it would reboot twice and that it was normal. it rebooted into twrp and did nothing afterwards. i rebooted it from the recovery and all it did was reboot back into recovery. i decided to flash a different version of twrp and still the same. then flashed clockwork and still got the same result. i wiped the bootloader and basically went through the rooting process again. flashed the latest version of twrp and the phone is still only booting into recovery.
i am at a loss because this is as far as my knowledge goes. its like the phone is stuck still trying to wait for that factory reset from the jellycream rom or something and it wont do anything else but load TWRP.
If factory hard reset will not work (with phone off, press power and volume up together for some seconds. You might want to try also holding home on the touch screen.) flashing firmware will fix it unless you have hardware failure, which I doubt.

Part 1 can be tricky, so take your time and get that right before proceeding.

so far i get the grey LG screen with 'booti mmc_read xxxx' at the upper left with the hard reset. it only takes 2 seconds to show up but the phone shuts off if i continue to hold the power and volume buttons. ill read up on that link here.
I missed that you wiped bootloader. You need that . So you could maybe just install the wkpark bootloader in recovery. You would do 1 and 3 here (1.25a file is down the page)
http://forum.xda-developers.com/showthread.php?p=39130435
I think Jellycream actually requires you have it, if I remember correctly.
Not sure why factory reset would cause that issue, but it will definitely not start without bootloader.
Flashing firmware will also write the (stock) bootloader if that does not do it. It will also reinstall the OS if system is corrupt or missing.
I can't find the thread for Jellycream2. Would you post a link? Are you sure it is for P920/P925 (same device, one is AT&T branded. I have the Thrill P925). If it is not for those device numbers, you may need xbsall's unbrick guide.
Also, if Jellycream2 is based on ICS and you were on a GB ROM, you would likely have needed to first upgrade to ICS and then install the ROM.
I'm just trying to understand why a factory reset could brick your phone...

ok basic rundown of what i did in the last year;
when first played around with rooted it about a year ago i used all-in-one to do it. i had already upgraded to ics using the lg mobile support tool prior to rooting. rooting went off fine until i installed a Beats Audio app from the play store. when the phone rebooted after it would be stuck at the grey LG logo. i didnt know what to do so i used twrp and wiped the whole phone. then i used all-in-one and flashed the ICS bootloader and did the flash kernel 4 fix or something its one of the last options to do. then using twrp i flashed ICS_V20_P20, Stock_V20P_Rooted, and a Thrill Update, the phone rebooted fine in an ICS rom but it ran like complete ****, so i tried various roms and the one i settled with was called OptimusRS V1. i used that up until 2 days ago when i flashed the jellycream rom.
after i factory reset that i tried to flash the different wkpark bootloader and twrp that came with the megatron tool hoping that would fix the issue. but it did so i reflashed the original twrp and ics bootloader from all-in-one.
failed to mention this before but i tried 3 different recovery files in between each attempt and it would flash and reboot fine but the phone would still do the same thing and just load recovery.
ill find links when i get off work today. thats the basic history of the phone though.
Hmm. Stil not sure then . Maybe a corrupt zip or you wiped something important. Flashing with LG Flashtool should recover it. And always make a Nandroid backup before installing anything from recovery.
http://forum.xda-developers.com/showthread.php?t=2392309
thats the jellycream rom.
im downloading the files for your xbsa rom at the moment. i do remember yesterday when i used the megatron tool i saw an option to flash the stock bootloader and recovery. i tried it but all i got was the pink LG logo then a security error message below it and the phone shut off.
Oh, ok, OptimusRS's ROM.
Hmm, I thought v20 was GB or something... If it is not ICS then that would be the problem. Also it does say there you need wkpark bootloader for that ROM.
Also, xbsall's v28B includes recovery but it is in system partition. I don't know if that ROM requires you install it from recovery partition or not.
If you still want Jellycream you should be able to flash xbsall's ICS v28B (the normal partitions one, not large partitions), then install wkpark bootloader 1.25a in recovery, then the ROM.

well that breaks down that a bit better. my progress at the moment is step f6. when i connect the phone nothing installs though. it just reconnects and disconnects every second or so. im guessing its because i already have those files. dunno though. i cant get my pc to install the adb drivers for the life of me when the phone is connected in recovery mode.it sees the new hardware just cant find the files.
actually i got it. for some reason the phone wouldnt install anything until i put the battery back in at that step. i continued successfully to step M. the phone is setting up my google account at the moment.
will flashing the baseband be necessary if my apn and sim work like the phone is now? my provider is h20(canadian i heard) but im the usa.
HUGE thanks regardless
Cool :thumbup::beer:
The no battery part is just for driver install, which is fiddly for this phone. Sometimes trial and error is a factor.
The baseband you have now would be the one you had previously. If it works, no problem. The one in the v28B pack is supposed to be optimized for the v28B .bin file, but hey, whatever works.

im only getting E for data. i tried to flash a baseband meant for at&t but it says failed after about 90 seconds. still no 4g though. i did flash the xbsav8 before i set my apn up. i might just go with an optimusRS rom again though. i was happy with it. probably not jellycream this time.
Baseband fail after 80 or so sec is normal. It means it worked. Check your baseband in android settings/about phone.
You might try speed test app to compare actual speed. ATT 4G icon is a lie on this phone IMO.
Now that your pc is set up you can flash any P925/920 bin. Kdz files (combo of bin and fls, there is another tool for flashing those files) can be extracted into separate bin and fls, but I have not done it. The advantage is you can flash baseband separately.
Xbsalls vX3D (see his page) with the P925G fls file gives me 4G icon on Straight Talk in the US, but I like his vR3D better, and I can't tell a speed difference, honestly.
I have not actually measured the speed in either, however.
And for either of those ROMs, you must flash his large partition version of v28B first...very important.
oh its definitely like 2g speeds. its pretty slow. i tried using my providers app and website and its saying the phone i have isnt registered to them anymore so it might be just that. if thats the case ill just bring it in so they can do that for me. when i rooted it the first time i wasnt getting any data and they had to re-register the phone to get it to work right.
my baseband says OMAPP4430/XMM6260. for comparison and/or confirm differences. i have no idea lol.
side question though; my sdcard still has recovery files for the optimusRS v1 rom i had on it. i really liked the setup i had when i made the recovery for it. Im tempted to reinstall it but im really not too sure if itll work or worse harm my phone again.
Lots of variables, but you must remember that xbsall's P940 recovery app he he uses has recovery in system partition. The recovery you had before was probably in recovery partition. They write restores from two different places. Probably you would get an error, but not positive. Understanding that may take some Googling...
If you try it, back up before trying to restore the old backup. Then you could hopefully restore if the restore fails, know what I mean?
Probably the safest thing is to use the all in one tool to install recovery in recovery partition and use that one to restore backup.
I do know when I have restored backups, I have wiped Dalvik, Cache, and Factory Reset (in recovery) and then restore. Then it works. Some people wipe system too.
You can usually flash to recover from a problem, but then you have to set your phone up again
Well I recovered everything. All settings and personalized stuff. Just everything. Everything is running normal again. Just now my data is saying im using an h20 microcell instead of just H20 with a 4g connection. This 2g stuff is for the birds. I'm almost thinking the firmware we flashed has something to do with it. The phone is functional though. Just slow and no mms. I haven't been able to find much on the forums about it. I'll poke around more tomorrow.

I'd try another baseband.
I was looking at this link...
http://android.sc/downgrade-or-rest...to-oficial-stock-android-jelly-bean-firmware/
And this list of images
http://sbf.droid-developers.org/ghost_rcica/list.php
I have the americamovil-pr image stock on my xt1058
What would happen if I used rsdlite to flash say the rogers or att version? I did a little googling and saw people used rsdlite to change images with RAZR HD gsm models but wasn't sure if this is the same and just wanted to ask just in case.
Would I be able to do something like flash the T-Mobile image which is xt1053 without doing irreparable harm to my phone?
I appreciate any help with this greatly. If there is no irreversible harm I would be willing to try the T-Mobile image on my phone to see what happens
It may or may not work, but you should always be able to just flash the proper image if it doesn't work to get it running again. For what it's worth, I tried flashing the T-Mobile stuff on my AT&T phone yesterday, and it wouldn't pass the verification stage so it didn't flash.
