[Q] Nexus S 4G won't boot past Google Screen!!

I tried rooting my phone, but when I flashed CWM my Nexus S stopped booting... it freezes on the Google screen in the intro. I can boot into Fastboot, and cwm, but I cant connect the Internal memory to the computer without it booting like it is supposed to. Does anybody know of anything I can do to fix my phone and bring it back to stock??

There are guides for returning to stock stickied in the Nexus S 4G Android Development forum.
Before you do that though, try flashing a different recovery, like the one linked to here or here.
Btw, which guide did you use? You're not the first person to have this problem, and it's really bugging me (though probably not as much as it's bugging you :-o).

I will try a different recovery, but how would I flash a rom if I can connect my phone via usb mount?

I'm a little out of my depth here, but I think it's
fastboot flash system system.img.
You don't need to put the rom image on the sdcard. Just put it in the same folder as fastboot.

It was titled "How to Root Nexus S!"
And I will try to flash recovery and try that rom command, thank you )

There's a button for that.

I got the link. Thanks. I looks like you flashed a boot image that is incompatible with your phone. That guide was for the T-Mobile Nexus S. (Why they're screwing with the boot.img to begin with, I really don't understand.)
Download the attached file, and unzip it to the same folder as fastboot. The md5 sum is d4a9508f9321eb25df3383f00f571e8b. Then
Code:
fastboot flash boot boot.img
You'll probably also want to use one of the recoveries listed above to
Code:
fastboot flash recovery recovery.img
, but leave system alone for now. Flash that only as a last resort.

OMG!! im having the same issue. could you please post the link for ODIN so i can return to stock and take it from there please? I rely on my phone so much and i need it asap thank you.

same problem with me.
but in my case, the phone not only freeze after the google logo before boot. I tried several times to pull the battery and start the phone again, it took several times until the phone can boot normally again.
After that, my nexus s can work as usual. but it only takes 3-4 hour until it freeze/hangs or reboot automatically and show image of green robot lay down with red alert triangle...
sometimes I noticed all application force closed like gmail, gtalk, etc. (its a basic apps instead of 3rd party app)
History :
- root GB 2.37 using superoneclick
- upgrade OTA to ICS 4.04
- problem happens
- root using guide : nexusshacks.com
- unroot using guide : nexusshacks.com
- back to factory setting on GB 2.34
- upgrade OTA to ICS 4.04
- Still got that problem.....
I'm using Nexus S 4G Sprint, pls help me guys...

nexus s won't boot
I had the same problem and read elsewhere that heating the phone with a hairdryer solves the problem.
I must say, indeed it did.
I removed the battery and the SIM card, then heated up the phone (so it really feels warm) put back the battery and sim and simsalebim the phone started again. and is still working since (now already a few day's)
It seems that a component in the phone is heat sensitive, the question in my mind is when will this show again and do I need to consider buying a new phone.
But sofar it works
PS I also tried hard reset factory reset the lot, but in the end only heating up helped.
Good luck, David

I fixed this problem! but I had to wipe all user data by rooting it using nexusrootICS. It finally boots up and the phone works now... that's all I need.

LG VS840 Help!!

Got a bit of a problem.... I flashed a ROM onto my phone (forgot to back up, that's my big issue) It said it flashed just fine. Went to start up, just ran the lg logo for about 30 mins. Decided to try re-flashing it. Made sure to wipe everything. Nothing, still have the same issue. Tried to get back into CWM, but its gone now. Tried doing emergency download software, now its stuck on the screen "Download is in progress, do not disconnect cable." Im stuck. I dont know what else to do. I've tried the LG Support Tool, but it says to use Verizon Software Upgrade Assistant, which I can't get because I can't find a download for it and I cant get it from my phone.
I have the stock ROM image, but I have no clue how to install it without CWM or something. Any suggestions? Any help would be greatly appreciated! I needs my phone...

they said to use Upgrade Assistant that means you never told them about the truth: phone is not booting....big mistake or let me understand that:Upgrade Assistant works when your phone is in download mode ?!
what is that rom you tried to flash surely was for your phone ?
also you have stock rom this is a .zip file or what format?
can you enter fastboot mode ?

Um... Let's see... The LG Support Tool which in most cases you can use to return your phone to stock comes up with a message saying "Upgrade tool is preinstalled in your phone. Please allow to install "Verizon Wireless Software Upgrade Assistant" when the phone is being connected to the PC". That's what the tool tells me.
The ROM I tried to flash was BrokenOutConnect v1.0. Its for the LG Connect, which is almost the same phone, and some one said it would be ok to flash it.
The stock ROM is in an .img file, so I need to figure out how to install from that
And I have no idea how to enter fast boot (unless your referring to the vol up+down + pwr, in which case, that doesn't work.
Sorry, can't post the original page for the ROM, I'm too new lol

ok
I think was a bad idea to flash that rom because is not exactly made for your phone one can damage a phone in this way never do like that !
about your stock rom...maybe this is a backup made by stock recovery ? do you have a recovery.img file in that update ? there is a single img file in that stock rom or more files ?

No I do not... I actually just found that stock image on another forum. File is called LG_Lucid_VS840_4g_system.img . I realize that was a horrible idea... Google kinda led me astray on that one lol. I just wanna figure out how to return it to stock. Or if anyone has a link for "Verizon Wireless Software Upgrade Assistant", that would be much appreciated.

but do you have a backup of your current rom on your sdcard ? It's made by stock recovery if so search for a file named recovery.img
here is the link to your phone check if this is really your phone also download usb drivers and software to update it from LG site
install USB drivers then download and run LG Mobile Support Tool this will connect to LG site download files and finally will request to connect phone to PC then will make update

Note 5 stuck on boot after MM update, DRK is missing? Phone was never rooted

Hi, I have searched numerous forums and I haven't found a solution yet. A friend of mine updated his phone to MM the other day and it got stuck on samsung boot screen. Phone has never been rooted, so I decided to use Samsung Smart switch to do a system restore. During the process, an error message popped up saying "DRK" is missing". Then I tried using ODIN to do a system restore with stock firmware, same problem came up.
Any solutions would help, thanks

not sure how much time you spent looking, but a simple Google search yielded this thread. i have no idea if this will work for you, just trying to help. see this DM Verity thread, too :good:

I had the same problem. You need to ODIN the original firmware then let it boot normally. You will then see a DRK Missing error. Reboot to DOWNLOAD mode and flash the SPACEX_KERNEL MM N920C.tar kernel( you can find the kernel on xda or google). Let it boot again and you will see the same DRK Missing error AGAIN. Just restart your phone and it should works.

Thanks alot guys!

Thanks, I will try this method if there are issues later on. I read that the other method is a temp fix, I won't be able to perform a factory reset without running into the same issue. Have you tried factory resetting yet? I wonder if it will get stuck in a boot loop.

I followed one of the links and it worked! Thanks. I did come across it, but I didn't try that instruction. I did follow a similar instruction that required me delete several files from .tar, but that didn't work. So I tried the one you sent, this one just require to delete a file out and it worked. I read somewhere that it is a temp fix until the next factory reset.

LG ARISTO [LG M210 T mobile]

Hey guys! How ya doing?
Im pretty straightforward so I'll make this fast.(like myself in bed with a 10/10)
I need some help on my LG Aristo (T-Mobile).
The problem is I rooted it via fastboot with twrp and everything went great for the first few days until it started to flash gray and wanted to become an alien.
I wasn't worrying cause im a thug.
So I attempted a re-flash & I erased the recovery then re-flashed it.
Until the blinky gray alien screen started happening again.
For a few days I tried everything and the gray flashing screen wouldn't go away.
So I did the following fastboot commands and it went away.
Fastboot erase cache
Fastboot erase userdata
Fastboot erase system
Fastboot erase recovery
Satisfied that the gray flashing finally went away I reflashed it with the twrp recovery.
Only this time when I booted into twrp to install No-verity and SU all I seen was
Failed to mount :/system
Failed to mount :/userdata
Failed to mount :/recovery
And the phone did a reboot and was acting funny.
I then re-flashed the boot, recovery and the modem imgs that I extracted from the KDZ myself. And it actually booted but stays stuck at the LG Logo.
I couldn't flash the system img as I kept getting a "max target size download of 190840823 bytes" error.
I looked into it and a friend mentioned to forget it and to just flash the KDZ File with a LG flash tool.
I tried this only every flash tool I used did not pick up my device model. (yes I had all correct LG Drivers installed)
Aftering searching online I also tried to replace the fastboot exe with mfastboot. But it did not work as I keep getting the same error but it said target -max-download size of: 250mb and my system.img is about 2GB+..
Also, the mfastboot was made for moto devices (I found a XDA thread that linked it) and not lg. But it didn't work anyway.
I really think everything will be solved once I flash my system img but I keep getting errors about the size limit. (If you know of a way to fix this let me know.)
:good:I've already tried the following so please don't bring them up::good:
*Erasing everything via fastboot ( doesn't do anything)
*Putting phone into DL mode to flash KDZ and TOT file with phone dll via LG flash tools.(2014 and 2016) ( kept getting a (s) failed to load error)
*Re-flashed stock imgs (done it all but system img. I don't know why It keeps giving errors, yes I put it in android sdk platform tools folder)
* Put phone in dl mode and use LGUP/uppercut method. ( Kept getting "No handsets connected" errors". Phone wasn't recognized no matter what drivers I used.)
*Try different ports on pc and latest drivers. ( Yeah, I spent a week searching for all drivers and my pc isnt a virgin anymore as I stuck in the usb in all her holes)
*Relentlessly search XDA and other forums for solutions to no prevail. (This phone is irrelevant and no one cares about it)
:good:What I haven't tried::good:
*Breaking the mother****er and just buying a s5.
Greatly appreciate any help and also can XDA add the LG Aristo to the "my devices"? I had to pick a s8 so I didn't look broke.:silly:
I didn't seen an LG Aristo and There is NO forums for this problem or even for this phone in that matter.

Use Uppercut with MS210 Firmware Typically, if you can't get LG Bridge to recognize device you should pull the battery out with the cable disconnected, reinstall the batter and then hold the Volume Up button and then plug the USB cable in while it's connected to yuor PC. Welcome to the miserable world of LG

Any solution for frp lg ms210?

Has anyone had any luck unlocking this phone?I would like to switch from T-mobile to Freedompop.
