IDK if this is the correct area for this, but Imma try here anyways. My friend upgraded his old S8 to the S21 5G about 2-3 months ago and has been having problems since a Samsung firmware update said his device had an error that needed to be repaired and had pronmpted min to check for an update, which it apparently found, and he had attempted to download and install it while he slept. Well, he woke up to find that his phone was now on the Odin screen for some reason. He took it to a T-Mobile tech center and they were able to get past the Odin screen by doing a Soft-Reset (Power+Vol Down, then Power=Vol Up after the device shut off) and it had worked for about a month. Queue the current issue... He's right back where he started, supposed device error, update found, attempted download and install while he slept, and waking up to the Odin screen. Only this time, doing a Soft-Reset does nothing. We've tried multiple tech centers and they all say the only solution is a full firmware reinstall, or to send the device in to be serviced, either way, that's the cause of the next issue. He has never used a Cloud service of any kind to back up anything on his device, and in doing a reset or service, he'll lose everything on his device, which includes numbers of recent friends and co-workers, photos that had been transfered from his old S8 to the internal storage since the S21 doesnt have Sd/Tf support, and a ton of other important infot hat he can't just lose in the process. Is there anyway to figure out how to potentially install a firmware w/o losing all the internal storage or some off-device program that could remove them. I have tried many different programs that say they can do what we're trying to do, but none have worked or have been up-to-date enough to even support the S21. I'll attach a couple files to show what I recorded of the kernel and the boot screen issue from my phone of his phone.

Phone specs:
Model: LG Optimus One P500h
Carrier: Telus (Canada)
Android version: 2.2
Kernel version: 2.6.32.9
Build number: FRF91
Software version: LG-P500h-V10g
Background:
I bought this phone (brand new) in late November 2010. Within a week or two the phone started randomly powering itself off (even when the battery has plenty of charge left and the phone is just sitting on my desk). I hadn't performed any modifications at all (no rooting, no custom ROMs). Hadn't even downloaded any apps by that point.
I have never seen it happen... I'll use the phone like normal, the screen saver blacks out the screen like normal, and then I go to use the phone some time later (a few minutes, an hour, etc.) and I find that the phone has powered off on its own. It happens when I have the phone sitting on my desk, so the power button is not being pressed accidentally. The frequency is intermittent: sometimes it will go for a few days with no shutdowns and then sometimes it will happen twice in one day.
At first I thought it was a battery problem (I thought maybe the battery was overheating and the phone was shutting off to cool down) so I went to Telus and they gave me a new battery. I tried that for a week but the problem persisted. So I took it back to the Telus outlet again and they sent it away to an LG-authorized service center for repair. Doing this cost me $30 for shipping + service charges because I didn't purchase an extended warranty and I was 1 week past the 30 day device exchange period.
When I received my phone back (the service bill said that a "software upgrade" had been performed) the problem still continues! The phone has been shutting down at random exactly the way it did before it was sent away for service.
I didn't want to send the phone away for service again so I tried updating the phone's software myself - hoping this would stop the random shutdowns. I downloaded & installed the proper USB drivers using the LG Mobile Support Tool (I needed to put the phone in USB debugging mode in order for the mobile support tool to detect the phone). Everything was going fine, the LG Update Software downloaded the ~100mb firmware update file (I think V10s) and proceeded with the install but somewhere near the beginning of the install the phone went into Emergency Mode and stayed stuck there. I left it alone for 30-45 minutes just in case this was part of the install but after the program stopped responding I figured this wasn't normal. So I unhooked everything and took the battery out hoping it would reset itself but every time I would power the phone on it would bring up the LG screen then proceed to a bright yellow screen with the text "Emergency Mode!!" displayed.
I tried a few methods to get the phone out of emergency mode (hard reset/factory reset, leaving the unit off for extended periods of time, trying the mobile support tool again, etc.) but nothing worked. The only way I was able to get the phone operational again was to download the original firmware (V10g), install the MS XML sp3 parser and run the KDZ software updater (with phonemode "EMERGENCY" selected).
So with the phone running like normal again I figured I would try the update again. Now when I connect the phone and run the LG Mobile Support Tool it says a new software update is available but then when I click on "Start Updating" it goes through it's initial checks then says that this model cannot be updated, and it won't even attempt to download the new firmware update.
I have found the V10s available here: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP500H/ATLSRB/V10s_00/V10S_00.kdz
But I am hesitant to try and install it with the KDZ updater in case something goes wrong.
My questions:
1. Is anyone aware of a fix for the random shutdown problem? I read through this thread
http://forum.xda-developers.com/showthread.php?t=944847&page=2
but I didn't see any concrete solutions.
2. Do you think the V10s software version will fix the random shutdowns?
3. Can you think of anything that I'm doing wrong? Why won't the LG Updater let me install the update now?
Thanks
unlikely to upgrade to fix something, most likely factory marriage.
before upgrading try to make a hard reset
when the flash in KDZ try disabled LG Modem Driver
Maybe a problem of a bad SC-card. Try a different one (insert the new one and format it in the phone, then copy the content of the original one via usb)
Thanks for all of your suggestions.
I'll try installing with the LG Modem disabled.
If that doesn't work I will purchase a new sd card. I'm still using the stock one that was provided with the device so maybe that's causing the problems.
Took an over teh air update while on a road trip this weekend and upon reboot, the screen is showing nothing but semi-random dithered pixels. Looks like the display is pointing at the wrong RAM or something.
Tried a hard reset. Nothing.
I would assume this was just a coincidental hardware failure and nothing to do with the update if I wasn't seeing other reports out there of exactly the same symptoms.
Spent 3 hours on live chat with Samsung (kept getting cut off and having to start all over again). They want me to send it back in - 4-5 days UPS ground there, 3-4 business days to fix, 4-5 days UPS ground back. So my one month old $500 product will be gone for 2 weeks getting fixed from the company's own SW update. (fun note - they do not appear to have actually updated any of their internal tools to support this device - I kept getting asked for a serial number then told what I provided was not correct -- even though it was the one printed on the box and the device).
Decided to see if maybe KIES could help (unlikely) and it can connect to the device and recognizes that it needs an update, but when I try to do the update, as soon as it goes to download the files, the device disconnects. Then when it reconnects, it does the same thing all over again - re-downloading the same files, losing connection, re-acquiring it, loop. loop. loop...
So basically, Samsung, epic FAIL. You really think this is how you go toe to toe with Apple?
Anyone have any advice on whether it might be possible to force the factory firmware back into this thing to see if it is indeed jsut teh firmware being horked instead of the video circuitry?
Do you have CWM recovery?
Most definately you can bring this back by flashing another kernel or ROM via Odin. If you already flashed CWM Recovery before, it's just a matter of clearing cache & dalvik cache. If not, flashing another ROM only takes 10-15 minutes if you are used to it. Or about an hour to read up and do your first flash (read the first post in the Android Development subforum. Come back here if it's not clear. Just make sure you pick the right kernel & ROM).
Mine did the same once with a previous update. It would start up eventually though (after several minutes). As mentioned in the previous post, if you can get into Recovery (hold Volume-Down and Power toghether until 2 icons appear), a wipe of the Cache and/or a factory reset will probably bring it back to life.
Samsung & software, it remains a troublesome combination .....
PS. If you have got it up and running, disable checking for new updates. Once an update has been downloaded, the Tab keeps bugging you with popups to install it, even though you tell it never to. 2 days ago, the update question popped right up on the spot i was to tab a link on a website, firing off the update instead. It immediately wrecked my Tab. Luckily i had CWM Recovery flashed earlier, so a clear cache & clear Dalvik cache solved it.

Moving to Q&A
Hi,
I’d really appreciate it if someone can help me, as I’ve not been able to find my exact problem and solution anywhere in the last 5 days of trying to fix my Samsung Galaxy S3 SPH-L710 – Sprint.
Not sure what happened but I had just swapped out my battery and my problem began – I have 3 batteries that I charge and swap when needed… one of the reasons I’m still using the S3. Been wanting to get a new phone but just haven’t decided which one and kept putting if off. Anyway… After charging the battery I turned on the phone and it got stuck on the Samsung Galaxy S3 screen. Went online and read I should try a cache wipe. I did that and got a bunch of failed to mount lines and a few other failures. Mostly failed cache. Not sure if this had anything to do with it but I was running low on the internal free space and had to delete a few things to make more space and then it would fill up again etc… Internal size is 16gb.
Here’s what I tried:
Attempted the 4.4.2 ROM flash in Odin. – Got a PIT partition message and then tried again and got write Failures after NAND started. Tried a few more times and same thing but I don’t get the PIT error anymore… I tried different Odin versions, computers, and cables, and same results. I have the correct USB driver. I’m using the same version ROM that’s on my phone, but the build name on my phone is last (newest) update and I could only find the previous build of the same 4.4.2 version. Note – This phone was a swap by Sprint when my first S3 had a start button issue. This one is a refurbished… not sure if that changes anything.
I also tried a TWRP install via Odin and it Failed.
I tried to Root via Odin and it Failed.
I DID NOT do a factory reset because I don’t want to lose all my data.
MORE INFO:
Phone is not Rooted and never was.
Phone goes into download mode and also stock recovery mode without any problems.
I never set the developer option and I didn’t enable debugging. Not sure how, now that my phone is soft-bricked.
QUESTIONS:
I’d like to preserve all my data and settings and somehow back them up so that I can put them on a reset phone.
Is there any way to work around this soft-brick and grab all the info including the system info and settings, all my files, and pictures, etc??… Everything! … I’d like to get the phone working again and put it all back on it and be the same as it was. I have so much important stuff on the phone. I have been doing backups via Kies but haven’t done it for a few months and I don’t even want to lose even a few months of data, and the way my phone was set up. Is there anything I can do to basically get a mirror image of my phone? Assuming all the information is still intact but it just can’t mount properly.
Is the developer / debugging setting preventing me from being able to do what I tried? Is it because I’m not Rooted? Is there OEM Locking on my phone?
Should I try to install TWRP from the stock recovery via external SD card? And then Backup from there? Is that different than doing it from Odin or will that fail too?
Please help – I love my S3. No phone for 5 days and I feel so disconnected :crying:
Thank you!
I set it to auto update at 3AM, instead it started to update at 3PM @20% battery, I was not able to stop it in time and it tried to update, entered bootloop forever, left it charging for 2 days, nothing still looping.
Tried flashing firmware with odin, flashes successfully but tried turning on-get bootloop, again.
Can go into recovery, can go into download, can’t do anything else.
Can I get data back in any way?
I heard chip-off recovery is not an option anymore since they are encrypted.

Thank you!
If you can't get past the bootloader without formatting the phone, chances are you can't do any other way. Anyway there are the copies of the samsung cloud, drive, etc.
any joy? same issue and samsung wont honour my warranty as run out 2 days ago
Hello XDA community,
I have a G965F that is permanently stuck on the first boot screen (Samsung Galaxy S9+ secured by Knox powered by Android) and it will not progress past this point. I have left it on for hours, and it just stays on that screen. Recovery mode does not work; if I try the button combination for it, it just stays on the same screen as mentioned before. However, I am able to get it into download mode. From here, I have tried flashing every firmware I possibly could, of course with the correct region and version, but nothing works, and the situation stays the same as mentioned before. Odin usually finishes up with no problems and reboots the phone, in which case the bootloop happens once again. On the rare occasion that Odin does fail, it will not boot even to the first splash screen but rather to the blue screen with the triangle, telling me to connect it to SmartSwitch and go from there. I have attempted this also, but SmartSwitch only gives some errors, and it fails.
The phone was on the stock firmware for a few years and even updated through Odin when OTA didn't work. It is a UK-unlocked Exynos device. About 2 years ago, I decided to switch to lineageOS using Neuroticals ROM, and that worked flawlessly, OTA updates and everything, 0 problems. I even went back to stock at some point and reinstalled Lineage shortly after because of how much it improved the device. About 9 months since I last did any type of flashing, the phone randomly froze while I was using it (I think the bottom half of the screen went black) and was totally unresponsive until I forced shut it down. This is where the aforementioned problem began.
I thought letting the battery run out would help, but it hasn't. One thing I have noticed is that it either charges very slowly or doesn't at all; it will only stay on for a maximum of a minute after it is unplugged. I left it for a few months, hoping to discharge it completely, but the problem persists.
Apologies for the lengthy post; I've used this site for about a decade for mods on various devices and it has solved all of my problems, but this is the first one that has really stumped me. For the past few months I've spent tens of hours searching various forums and webpages but can find very little about my specific problem. Thank you for any help in advance.
I will include pictures of the codes that download mode shows, and hopefully someone has some answers.
PS. For some reason current binary says "Custom (0x8)" after successfully flashing the stock firmware many times with Odin, but when Odin does fail it will show "Samsung Official". This I cant make heads or tails of.
