[Q] sch r915 with bad rom no recovery or download mode - General Questions and Answers

hiyall!!!
lurking for years but just finally had a problem to post.
i have a samsung sch r915 that i accidentally installed the basix rom for a r910. i tried to get into my clockworkmod recovery, but i cant get into restore or download mode, as only the power button seems to work. when i turn it on it shows the samsung logo for about a minute, then the backlight turns off and doesn't do anything past that. it will shut off and turn back on if i hold the power button for 3 to 5 seconds, if i just press it once nothing happens.
i tried power+r for rec and power+9 for download.
neither work
help would be greatly appreciated!!!
thanx in advance!

[Q] Triumph stuck at moto logo, cant get into clockworkmod

Ok so today my triumph stopped responding so i restarted it (took out the battery). then rebooted. upon reboot phone shuts down and now will hang at the motorola logo for about 10 min before boots but will shut back down due to the battery being dead(but had full charge when this started). Dont know what happened. So i try to get into clockworkmod to flash backup. cant get into it. the only thing i can do is get to the recovery.img file(pressing power+volume down). Other than that nothing.
also tried to boot with power pluged in. it stayed on but would not respond to any touches or button press except the lock button.
I have cwm 5.0.2.6 installed and tickerguy's cm7.
never had this problem till today. Any help would be appreciated.
a new development has occurred. now when i try to access recovery, the phone will just vibrate without stopping.
and i believe its stuck in a boot loop but without recovery i dont know anyway to exit the loop.
Are you able to get into download mode (power off then simultaneously press power button & vol- (should show polling))
Sent from my Triumph using xda premium
Yes i am able to get to download mode
Well after some tinkering (replacing the recovery image, assuming something corrupted it) i can now get to recovery, still takes 10 min to load it though. But i am unable to do anything in recovery because i have to press the menu button to confirm selection but the buttons wont respond. Some help would be appreciated.

Unable to boot GT-P6200 in recovery mode

Hi
I cannot get my Samsung Galaxy Tab 7.0 Plus (GT-P6200) to boot in recovery mode.
I tried the following:
1) Switch off the Tab.
2) Press the Power + Volume Up buttons simultaneously until I see the "Samsung Galaxy Tab 7.0 Plus" screen, then release the Power button and keep pressing the Volume Up button. The tab then get's stuck on the Samsung screen, even if I release the Volume Up button. It stays on this screen indefinitely, only option is to reboot by keeping the power button pressed for 5 seconds.
Any help will be appreciated.
Thanks!
same issue
I am having the same issue as well. My tab gets stuck on the "Samsung Galaxy Tab 7.0 Plus" screen and does not move on from that. When i try to boot in recovery mode the screen is just black and slightly illuminated. Please help

Same problem
any help ???
On which verison thar ur on???? have u tried to wiping data in stock recovery
??
same problem I'm having with my Samsung Gt-p6200, it just boot-loops to the "samsung galaxy tab 7.0" boot loading screen and hangs.. these happened after i flashed my firmware from stock honeycomb to jellybean(the austria firmware, i think that's been posted in this forum).
here's what happened before the problem:
-I flash the stock honeycomb firmware with the jellybean one that i found here..
-after i flashed using ODIN, the new firmware works great, i was even informed that i have free 50GB worth of dropbox space,
the file was named P6200XXMC3_P6200OXAMC3_ATO
- I have used it for a day, until the battery drains and i have to charge, but when i opened it again, it already does this "boot loop" problem
- i have tried flashing CWM with ODIN(as i've read here somewhere that it might help) and do that wipe cache and factory reset thing but that didnt help solved the problem.
hope anyone could help me, im also thinking flashing it back to it's original stock firmware but I dont have a backup of that and I dont know where to get one, I've been searching the net for two days for that stock rom but all i found are the new jellybean ones and some old ones but is uploaded to hotfile which is now deleted or locked.
I hope you guys could help me out and thanks in advance!
try flashing a new , latest firmware on odin

Hello guys! Im also having this same issue.
*Using the same firmware that was posted here in xda because i was having trouble downloading those official jellybean firmwares
*The battery got drained
then if i charge it, it will remain in a "blank slightly illuminated screen"
* after a few munutes, the tab gets really warm.
*but if i dont charge it, it will get drained again because it keeps on turning on itself back to this time to the "galaxy tab plus screen"
I cant access recovery mode.
I can access odin mode and can flash successfully with cwm or the same firmware back but the problem still persist.
I havent tried other firmwares though.
4 days passed already and i cant figure this out
Please help
So I had this happen to me yesterday, where it rebooted randomly on me, only to freeze on the Galaxy Tab 7.0 Plus screen. I had custom recovery (TWRP) don't know if that matters, but I was able to access it by holding Power+UpVol but keep it held. It would freeze on the same spot but since I was still holding the keys it reboots a second time and this time it would go into recovery.
I then wipes cache and dalvik, no go. Sadly did a full wipe. Still no going past the tab plus text. So I flash MF1 official 4.1.2 firmware (I was previously on 4.1.2 UK official) still no go. Put in latest 2.8 TWRP and booted into it still with some trouble as I mentioned above. Did another wipe and it then hung on blank screen or so I thought. Took a long time to boot and after a long time, and the Android is upgrading message, by some weird chance I was on the MF1 official rom but all my apps settings everything was saved.
Working 100% now and I still don't really know what the hell happened. But if this helps anyone then all the better!

Power button Failure, Can't go into Recovery, Download.

My power button decides to become unresponsive.
So I tried to unroot my phone and bring it back to a stock image and when I go into download mode, 2 seconds later, it turns off. :crying:
I try another method by using mobile odin to see if that helps. Tried to flash the stock image and it tried to reboot to Recovery mode. Nothing. It stays in a black screen after the samsung galaxy s3 logo. After pulling the battery, it tries to reboot to recovery again and still, a black screen. The only way to stop it from booting to recovery is to set it back to download mode. I hold the power button and it restarts. ( The power button seems to work when I try to go to recovery, download, power on.
I am running Cleanrom 6.0 R2.
I am in deep [email protected]#!. I do not want to go to verizon and notice my phone is rooted and I can't fix it without a huge bill.
Please help if possible

[NEED HELP] Bricked my phone with low chance of any recovery

I need help urgently. I tried to change the splash screen of my Samsung Galaxy A51. I downloaded a custom param tar file, placed it in my downloads folder and used this command in adb shell to replace the older one. I did back up my old param. But there's no way I can restore it. Now, my phone when I try to start it. It doesn't even seem to turn on the screen anymore. I hear the phone vibrating every 2 seconds so I assume it keeps rebooting. I tried to enter download mode but I can't because samsung made it that you need to go into the recovery first, so I tried to go into the recovery but nope, it keeps vibrating and it's not responding to whatever I do. Is there still any hope for my phone? Thanks in advance.
Hello, I had this problem too. My phone also stopped booting into anything, even in TWRP.
For me, the resolve was to make the phone force reboot by holding power button and volume down, then immediately try to enter the downloading mode by holding volume buttons, when the screen turns off
and then you need to flash your device with your stock ROM
I understand you, that you cannot enter the recovery, but for me this method worked
I managed to solve it, the problem I had was that I was unable to boot into download mode. Because I have a samsung galaxy a51 and I did not know how to enter it. The last phone I had was a samsung galaxy s7 edge, back in the old days it was easy to enter download mode, just hold volume down, power button and home button. Now for some reason I need a cable connected to my computer and then hold volume up and down simultaneously. After I figured out how to enter download mode I flashed stock rom and phone worked again.
