Hi, I am new to this, but I am learning fast. I have a RCA tablet (rct6378w2) that will not boot. It powers on, but hangs on the RCA splashscreen. I am able to access the recovery system. Wiping the cache and factory reset doesnt seem to fix the problem. Because the tablet powers on and the screen works okay, I feel like there is still hope for the device. I was wondering if someone could list all of the common reasons why a tablet will power on, but not boot into android. Extra credit if you can tell me which possible problems are fixable and which ones are not. Thanks!

1. ROM is wrong for the tablet
2. Tablet has no ROM installed
These are the issues possible for you as you say you wiped and factory reset the tablet but did you re-install the ROM afterwards ?

Thanks for the response. Well, to give clarity as to when the problem began, this is what happened. I was doing normal things on my tablet, and it seemed to lag really bad. As I tried to press the home button once or twice, I saw some strange lines on the screen as it faded (kind of like when a battery dies). Then the device restarted and hung on boot. After rebooting a few times, I then tried to wipe the cache with no success. After this, I did the factory reset. I know that it cannot be the wrong ROM, but I wonder if somehow the files were corrupted or if the storage unit could have failed. Anyways, according to various instructions I have seen online, I thought that doing the factory reset would restore the original factory rom image? Am I incorrect?

Depends, if it's a custom recovery it could wipe everything

Thanks for the response. I have only used the regular stock recovery that is preloaded on the device (I think it's called Android System Recovery 3e. To my knowledge, I don't believe there are any working custom recoveries for this device. It seems that doing the factory reset is normally the way to go to fix OS issues on this device. However, when the factory reset process is successful (as far as going through the process is concerned), but it does not fix the issue, it makes me wonder if the factory recovery image is corrupt or something. Any ideas? Also, if the device turns on and I can navigate through the recovery options and even use ADB, do you think the hardware is still good? If so, then it would be a software/firmware problem... right?
I would simply like to get the device working. I don't care whether its a stock recovery or custom recovery, stock rom or custom Rom. I just want to use the device again and not have to throw it in the garbage. Do you have any ideas how I can get it going?
One other thing, I just don't understand why it's so difficult to restore a tablet. A PC is ultra easy to fix by using a self-booting recovery disk or a live linux iso. Perhaps someone can explain to me why it seems to be impossible to find a working rom anywhere for this device.

Unfortunatley because it's not a common brand of tablet not many developers are working on creating ROMs for it
Been having problems a while now, they've been progressively getting worse. Seemed to happen after an update.
Basically the phone freezes and reboots. Can be anything, unlocking, playing games, opening internet browser, opening gmail. Just frustrating, the phone just freezes, then reboots and loads up. Progressively getting worse and just gets hotter and hotter which seems to throw it off more. With the exception of a Software problem from the update (Damaged O/S and/or Bootloader), I'm starting to think the phone may be damaged. I've dropped it a fair share of times, but it's in a case :cyclops: so shouldn't be too bad
What I've done so far
- Cleared cache via Recovery Mode, this temporarily fixes it, the phone boots up again normally, but randomly freezes and reboots again
- Booted phone in safe mode - same problems
- Factory Restore --> Phone restores, but even when installing the apps again in goes through 3/4 reboots
I've enabled Dev Options and USB Debugging (and also OEM Unlock). If I try flashing with ODIN I just get a SW Check Revision failed message.
When the phone gets stuck in it's boot, it just displays the initial "Samsung Galaxy S7 Android" screen and nothing else, the occasional Samsung loading screen, but that sometimes freezes too. The times when I can get into the recovery mode, I've looked at the last log files, and there's sometimes errors relating to /mnt and a couple of directories, but I don't know enough about the O/S to troubleshoot and sometimes it fails to get into Manual Mode, I'll see if I can get photos of the last log file. The reboot reason is UNKNOWN
I've installed ADB, when the phone is loaded up into Windows, and I use adb devices it shows up. When I go into download mode, it says "List of attached devices" and then shows nothing. So I'm assuming it's a different issue, otherwise it wouldn't work in windows either
Bit stumped now. The phone isn't rooted, I'm not bothered about losing data, since I backed it up the first time I factory restored, so there's nothing valuable on there. I'm just getting tired of factory restoring it, since I don't think that's the problem. I'm thinking either the Factory Restore image is damaged or the phone is.
Any suggestions would be appreciated.
Phone is UK Based on Giff Gaff network. These are the files I'm trying to use to flash it
The option isn't ticked in ODIN (3.14.4) to Wipe Partition either

Hello the SW Check error means the firmware your trying to flash is older than the firmware already on device. You can only flash the same or up, never down.
The firmware you've posted is quite old. The unbranded original for United Kingdom you need is BTU. I linked it off Sammobile but if you know how to use Sam Firm tool you can get it much faster direct from Samsung.
If problems persist after flashing this, then yes it's a hardware problem.

Thanks,
I've got the SamFirm download tool because I was irritated waiting for the download, I'll try downloading and flashing it.
Should I flash the lot, or just one specific thing?
Also, I used Sam Firm to download the firmware for the phone but using the Auto Method.
What is the "Version" I need to enter based on SamFirm, is it listed somewhere, or is it the phone itself? G930FXX8ETC1 ?

You don't need to specify a version just put in SM-G930F, then BTU in region. It will automatically find the correct firmware for download.
Download, let it do its checks. A zip file with 5 files inside, 2xCSC, only one goes in Odin. CSC_home will keep files and settings on device but can often cause problems. I alsway use just CSC for a clean install. Obviously put the other files where they need to go too.
Sorry yes, flash all files, you'll have a clean new phone.
First boot can take about 5-10 mins, and the updating, erasing screens are normal.

Thank you, I managed to figure it out, I'm sure it's what I did last time, not sure if it just picked up the wrong version somewhere. IT seems to match the info in your post anyway.
I don't give a toss about the data since I'm over writing it all anyway. Do I still ignore the option to wipe the partition in ODIN, or should that be included to?

Leave the default options already ticked in Odin. You don't need to change anything there.

Thanks,
Just finished flashing the image now, so going about the restore process to see if it's fixed it or not.
(still think it's buggered though, my phone froze/rebooted even when doing android config)
If needed I'll just keep using it in a semi-working state until I buy a new one and put up with it
EDIT - Just froze / rebooted configuring the main O/S after connecting to google account. New phone time by looks of it
Only other possible thing I can think of is the battery. There were alarms in the log file and the phone does reboot more when it gets hot. Given the phone is 4 years old now, I wonder if the battery is damaged and the phone is having a hissy fit

I'll give it a try for now, I've got the correct files for flashing it at least this time thanks, I''ll try replacing the battery in the future, and if I find out it fixes the problems I'll update the post. Or if I figure out what's causing it
After the most recent update my phone got put into a bootloop that wouldnt stop for some reason, it would boot and then after I wanna say less than 20 seconds it would reboot itself, and just kept going on in this cycle unless I powered it off when it was booted. Anyway I've been trying everything I can to get the damn thing working again so I can at the very least get my pictures off of it without factory resetting it and nothing is working, and I sorta feel like I've made things worse. I tried flashing with Odin but after that the thing just stopped booting alltogether so that kinda limited my options a lot. Now I'm trying to sideload an update from an sd card which might work if i can find the right thing to sideload onto it but before it gets anywhere it tells me error in /sideload/package.zip (status 7) so either I just need a different thing to sideload or something's broken. Either way I don't know how to get it working cause I have no idea what I'm doing here so now I need help.
My phone is SM-G970U SPR
Sounds like you are in a bad spot. If your pictures are on internal storage then flashing anything in Odin will wipe that.
I think you need to accept that they may be lost.
not so fast, i've used home_csc in all my flashes and when I finally got one working all my stuff was still intact. Now i just need to figure out how to get it to stop bootlooping.
Hello friends, I am currently crying in the same boat!
So, similar to Oske829 my phone ( Samsung Galaxy S10e ) has entered into a bootloop after a recent update that occurred roughly on February 06, 2021.
I am also experiencing the same symptoms as well:
My phone starts to boot up, then fails and Approximately 20 seconds after, it repeats that cycle. The phone continues to bootloop until drained of its battery then repeats this cycle again once if it is charged. **this is the current situation**
After playing around with the buttons, the only progress I've made is reaching the Download Mode. Ive yet to try odin or anything else and would like to ask for some help please! I really want to be able to save the data on there (pictures, music, apps, etc..)
Any help is appreciated, Thanks!

Download the latest official firmware with Frija tool (no download caps unlike websites like Sammobile etc). Just be aware that if you download and use Android 11 you wont be able to downgrade to Android 10.
After you have downloaded it unpack the zip and run Odin. In order to preserve your data flash the HOME_CSC file not the regular CSC... file. Once you unpack the files you will see.
The phone needs to be in download mode for flashing and battery is suggested to be at 40% or more.
Btw a good way to get out of bootloop and get the phone to shut down is to connect the USB cable (could be from charger or PC) and then press Volume Down+Power buttons to force a restart. It may be nessesary to do this a few times.
At one point you will not see the boot screen but instead it will show the lightning bolt charging logo and the percentage. After that you can simply unplug the cable and the phone will turn off.
In order to enter Download mode the best way is to start with phone turned off. Hold Bixby+Volume Down buttons and connect the USB cable from PC. Once you see the confirmation screen you can release the buttons and press Volume Up to continue.

So incredibly glad to hear I'm not a lone soul dealing with this issue. I've tried a whole bunch of things to fix this issue but nothing is getting me anywhere. I tried flashing android 10 but as that other lad said you can't flash older versions of android.
At this point I think my only chance of saving the phone is to wait for a new system update to release and flash that in case it somehow magically fixes the phone for some reason. I wouldn't recommend trying to flash atm because it doesn't seem to help currently and if you donk it up you'll lose your data which is not something either of us want to do.
I'll let you know what happens if I try flashing a future update.
Well i had an even bigger problem initially. Not only was my S10e bootlooping. My EFS partition was missing files (dont know how that happened). That meant that IMEI was blank and there was not network connectivity aside from Wi-Fi.
Unfortunately even the stock firmware flash does not fix EFS. Thankfully i had a backup (multiple actually) stored away including EFS. So with some fiddiling around in custom recovery file manager (TWRP) i manged to get that restored. I did lose bunch of pictures in intrernal storage tho. Thankfully it was nothing important. Now i keep everything on SD card and SD Cards backup in PC.
Now im trying to get the phone rooted with Magisk but the damn thing is not working.
This underscores the importance of regular (i had weekly TWRP) backups. I had backups of all partitions except internal data like pictures etc. Lesson learned i guess.
Hey RaXelliX thanks for lending a hand! Unfortunately I'm using a Mac Pro and Frija is a Windows exclusive *tears*
it seems that my next best alternative is to use Samloader instead of Frija, and JOdin3 instead of Odin. After some research ive realized that I am way out of my depth , but shall continue nonetheless. I'm gonna try your method with these alternatives and hope for the best, that sounds good in theory I was just curious to the thoughts of others more experienced.
And Oske829 your definitely not alone, stay strong and best of luck
Thanks!
There was a new firmware on Sammobile that I just tried flashing, didn't fix the problem, still bootlooping. I am officially out of ideas on how to fix this. I think there's something funky at the hardware/software level that's throwing a fit about having to run android 11 that's causing this, but I have no clue what it could be or how to resolve it. Not sure if there's anything i can do at this point to save my data.

You could try flashing a custom recovery (i suggest TWRP: https://eu.dl.twrp.me/beyond0lte/ S10e Exynos version) and the once in recovery connect USB cable to move the data off. If you succeed then you could wipe the phone and get out of bootloop.
When flashing recovery via Odin use the AP field and select the twrp-3.5.0_9-4-beyond0lte.img.tar file and make sure NAND Erase and Re-Partition are OFF. Auto-Reboot could be on or off.
This would touch only the recovery partition and will not wipe data unless you do it yourself inside TWRP.
There are a few caveats with this. The phone may complain about missing VBMETA header. If that's the case i will share a modified TAR file that includes that and TWRP itself. Or the phone could fail flashing custom recovery due to Vaultkeeper that prevents flashing unofficial binaries. This usually happens a day or two after flashing firmware. After that Vaultkeeper disengages.
Obviously your bootloader should be unlocked. You can do that by pressing Bixby+Vol Down before connecting the cable (with phone off) and then long press Vol Up to enter bootloader unlock mode. Bootloader can later be relocked again.

Is this exclusively for exynos phones or can I run twrp on a qualcomm device?
nevermind i found the snapdragon version of twrp
I'm trying to unlock the bootloader the way you described but that doesn't seem to be doing anything, and any guides I'm seeing on how to unlock it all involve doing something that resets the phone which isn't what I'm going for.

You might be out of luck as Snapdragon versions do not allow bootloader unlocks. At least as far as i know. I wrongly assumed you had Exynos version. If the data is important the last resort might be to contact some data recovery company. Im sure they have tools to access the internal memory even if the phone bootloops or flat out refuses to boot.
Flash 4 file firmware
Use Home_csc
If you want keep your data

I believe he already tried that and the phone is still bootlooping. Im betting that whatever causes the bootloop is in the data, the data he needs to access.
A bad situation all around because if he wipes the data it will likely fix the bootloop but he will lose the data. If he keeps the data the phone will keep bootlooping and he wont be able to access it. Although i would argue that the data you cant access is effectively lost anyway and that the proper functioning of the phone is more important.
I've heard that theres tools you can use to recover deleted data after resets and stuff since data doesnt get wiped when its deleted its just marked as stuff that can be written over. So I would think there would be a way for me to reset my phone to get it working and then recover the data with one of those programs, but the problem is from what I've heard you need a rooted device to do any of that and since I can't unlock my bootloader I don't think that can happen.
The one last thing I'm going to try before I seek out help from data recovery people is to try pushing the smartswitch apk onto the phone with adb and then hoping I have enough uptime to install it before the phone reboots cause I've heard you can use smartswitch in download mode to backup data, but I haven't found any guides anywhere about how this is done so I don't know if its actually doable.

Well I find myself here after 48 hours of s10e hell, with an almost identical issue. After a couple attempts and a trip to our local cell phone repair place, we ended up doing a factory reset, with the same hopes -- that the files were still there but the space marked as "free" and a 3rd party data recovery program could bring them back from the dead.
But they all require your phone to be rooted first - and this being my first venture into phone rooting I'm not really sure which route to go, or if it'll even be worth the effort. Does rooting the phone mean flashing it with a new OS, or simply unlocking superuser access so the recovery software can do its bit? (bear in mind, a lot of these products try to root the phones themselves, but none of them seem to work - I've tried about 4 different products thus far).
I'm convinced that if I can root this phone, the recovery software WILL find those lost sectors and recover the lost data, even after a factory reset -- there's plenty of youtube videos out there that say you can do this, but the rooting bit is what's got me tied up in knots!
huh.. jeah, latest update bricked my s10e too.
but my case, when power on phone, nothing happens, just black.. when conect cable to pc , then i can enter recovery and download mode..
till now nothing helped..
oem locked, frp locked, cant flash custom binaries!
hope next update will fix this madnes..
or need to find same firmware as update.zip what we can flash using stock recovery option (sadly saamsung dont give any update.zip files, i gues its money thing)
so, odin dont help, chimera tools dont help, and enginering combination file give some approval error to flash factory binaries!

well ,as far as i know, thease all recovery lost data works with HDD type disks, flash memory are out of luck..
because, i easy restored deleted data from my HDD, if it wasnt multiple times formated or writed full hdd , deleted, writed full etc.. but with SSD that software isnt working, due flash memory.. but, maybe im just to old, and there are new softs who can do that, just, i have not seen any jet!
Phone was working ok yesterday all day, then I has to take a flight to another city and timezone. When I arrived everything still was ok for about 1 hour, then I wanted to login in the hotel wifi and it wasnt showing the networks. Tried turning on mobile data ando it wasnt turning on either. Rebooted the phone, didn't work. Then I tried to go to the settings and I got an error message "Settings isnt working" and shuts the window. Another message that suddenly appears is HTC Mobile data Lite isnt working.
Tried with info settings > settings > clear data and cache. Didnt work.
Rebooted by holding power and volumen buttons, didnt work.
Went to boot options it says is locked and that ”File" wasnt found.
They boot to recovery gets stuck on the red warning with a triangle image.
Lastly the phone got stuck on reboots, after I do they security pattern it shows they splash screens and logos, reboots and asks for the pattern again.
Never flashed or did something with system files or kernels on this phone.
Wanted to try factroy reset but when I was able to go to the home screen and connect the phone to a Mac using the app AndroidFile Manager..? It said 8gb available to select, which seemed wrong as my phone was almost 60gb full, so wasnt sure it was going to be a good backup.
Any help on what can I do to backup ando solve the issue?
Thanks!
Clear system cache if that's an option.
Factory reset.
If that doesn't get it it will need a reflash. The flight may have caused a Single Event Upset, which is more likely to happen at high altitudes.
The hotel wifi is also suspect, root kit.
Lastly it could be a mobo failure or other hardware issues.
Is possible to clear cache if I can't access home screen? Any chance of backup before factores reset?
I don't think was wifi, didnt have a chance to connect to it or something
I think your stock rom has encrypted your phone's memory . If you want to S-OFF you can try a TWRP recovery otherwise you can install a RUU rom at home. All your data will be destroyed.
Figured out how to wipe partition cache...didn't help. Still stuck on boot loops.
All your data will be destroyed.

So there is no method to pull my data out of the device before trying to flash something into it?
Try starting it in safe mode. May take a few tries.
If you get it into safe mode, grab the data.
That's probably your last hope.
This is one big reason I always use a phone that supports an SD card. I use the SD card as the data drive; all critical data goes here. I then redundantly and regularly backup the SD card.
The data drive provides a buffer if the OS crashes/burns and most times is unaffected.
Everything I need to do a full reload/restore is on my data drive. It's time staggered backed up on multiple flashsticks and hdds.
I've lost whole databases before; lessons from the U of hard knocks tend to stick... and suck.

Already tried safe mode before your reply. Didn't work either.
Oh well, gonna go for the factory reset then.
Thanks for your help.

Try a few more times... play with it.
Been trying, keeps rebooting after entering the security pattern.
I can go to emergency call, it shows com.android.phone is not working but if I click wait after a while it shows the phone UI, I can take screenshots and move the volume bars... one time I don't know how or why, I left the phone while I read something else, on the pattern screen and I had the "Do you want to transfer files" message ... so this gives me hope that I will be able to either go to the system 1 time, or that the ADB is detected so I can pull data.
Tried fastboot boot twrp.img from power shell, but got the warning device won't boot. I guess because I didn't unlocked it and wipe the data first.
Found stock ROM that matches my CID/MID/Carrier, etc. Can I use this to flash something into my phone and fix the booting problem without wiping data?

The problem is likely in the user data partition itself. Start flipping firmware around all bets are off. Be a lot safer if you could get it into safe mode to retrieve the data.

Gonna keep trying to enter system then, maybe I get lucky.
The zip I downloaded had other zips inside and I can't open or extract them, windows says they are not valid. So I downloaded a different ROM from a different site, and had the same issue. Is this normal? Don't want to be flashing corrupt zip files obviously

The only boot loop I had where I needed data eventually booted into safe mode by itself after a couple tries at normal booting, convenient.
The next time it happened, a few days latter I was ready, lesson learned, always backup data.
As for the files, you're in deeper then I ever had to go. A factory reset be easier and safer if the rom isn't the source of corruption. You got yourself between a rock and a hard place. Personally I would have written the data off by now and factory reset. Of course that's because almost all the data was backed up.
Use the exact same rom.
Someone here can spot what's wrong though with your methods... have patience.
Seems I'm screwd. Did a factory reset, now I'm stuck on the Internet configuration screen after selecting language. Networks don't appear and I got the same "HTC Mobile Data Lite" error screen saying isn't working.
The top bar has a lock and only NFC is turned on. Can't pass that screen.

Didn't have one, then I inserted it again, no change. This was the original problem when I got in to the hotel, couldn't turn on wifi or mobile data.
Not sure what else to try. Wanted to try with a custom ROM or something, but can't unlock bootloader, because I can't get the identifier token since I can't get to the debug settings to turn on OEM unlock.
Fastboot oem unlock command is giving me an error.
The status of my software (on the bootloader) says modified, not sure if is it because I tried to boot a twrp.img (but afaik I understood should have been wiped after a reboot)
Extracted the zips with the RUU tool and got some img files, maybe I should try to flash some of those files.
Before you try anything else get the right procedure from an expert here. Otherwise you may trash the one or two shots you might have have.
I'm not that expert but there are members here that are. Sorry to see you having so much trouble...
I had the same problem,
This is processor fault .
the solution that i found to solve this problem is turn off the phone and heat the back cover under the camera using heatgun or hairdyer for about 30sec, don't make it too hot, then power up the phone and long press hardly the back cover under camera using your tumbs while HTC logo comes up. This makes my phone succesed booting up and the signal show up again. Once the phone turn up, just backup everything.
If the signal not showing up and wifi not working , you can use bluetooth tethering or using "gnirehtet" for reverse usb tethtring from computer.
*important : when the phone turn on, go to setting to delete the lock pattern/pin to make your phone not locked.
I’ve been asked to restore data and repair bootlooping A51. I’ve tried basic steps and resorted to updating firmware with odin. Recovery mode failed and I couldn’t enter it or fastboot. I’ve used home_csc to hopefully keep user data. Odin shows it passed, left my phone for 10 mins but it still was stuck. Maybe I’ve given it too little time to setup the new firmware.
Anyways now it’s unresponsive, nothing shows up anymore, no button combination works, nothing detected by my PC. Tried disconnecting the battery.
Everything was stock, pretty sure I’ve used the correct system version.
What can I do at this point?

Have it repaired. It sounds like something got corrupted and the bootloader won't start. The only way to fix this is with a board level flash, and Samsung/Qualcomm do not make the tools or the files available to do this. Most repair centers don't even have the ability to do this; they'll just replace the mainboard and program it with the original IMEI. Of course, this means that all user data will be lost.

Does it make a difference that after a while the phone responded and I can access download mode? I’m trying third firmware from a different source and still using home_csc to hopefully save the damn data.
Is there anything else I could try at this point? Still no access to recovery though.
What I am going to try now is to get twrp on the device and get the data off the phone this way. I don’t know if I can since I didn’t enable OEM Unlocking or whatever it’s called in the settings. Hoping for some tips, thanks!

If you're able to get into download mode, reflash the OEM firmware. You can try using HOME_CSC. Data wipe might be necessary if it bootloops.

If you didn't unlock the bootloader, this won't do you any good.
Are you seeing any error message on the download mode screen?
I forget if the A51 is a Mediatek device
Right now the device is dead again. I will be leaving it to charge and I hope it comes back alive, like it did before.
I’ve had bootloader errors on the download mode screen when I tried to install the firmware. At this point I am lost in what happened when, but I believe I got the bootloader errors when I tried to install the same firmware I’ve tried prior, so that doesn’t make sense.
I think the battery might be the problem here. It would turn off randomly before it bootlooped and it doesn’t hold charge now. The battery might’ve failed when an update was installing, but that’s just my detective work.
I will be replying with further tests when it turns on.
So, there is some weird behavior. After the phone charges for a few hours it tries to boot. If I hard reset it twice it dies. I need to hard reset it after it comes back and immadietly hold vol buttons to get it into download mode.
I can now experiment more. The original firmware version the phone came to me with is unable to install. Probably because I’ve already installed a newer version of android and it doesn’t allow me to go back. I’ve tried installing a newer bootloader and leave AP, CSC, CP. It fails harder, but I’m still able to try new firmware.
What do I try now? Data recovery is expensive, I’d love to try some stuff, but I don’t have enough time to do proper research and conduct experiments unfortunately.
Sounds like hardware problem if you can control temperature very precisely, you can try to remelt the solder if you know the temperature from the Service Manual. If not - leave to specialized service center who does this kind of thing all the time (ask them if they do).
In terms of flashing, to boot, maybe try Samsung Switch as it should be designed to preserve data however I am not vouching for it.
With Odin just skip the USERDATA and PIT
Doublecheck the exact model SM-Axxx ? Firmware files should be different per exact model.
