How to access recovery? - Samsung Galaxy Z Fold 2 Questions & Answers

Hello to all,
I'm on Android 12, OneUI 4.1, XXU2GVC5.
For some reason the smoothness when scrolling through news apps is gone. I did cleaning with CCleaner and SDMaid but it did not really improve. I tried to get into recovery to wipe the cache partition but did not manage. I shut down the phone, pressed and Volume UP + side key. The phone boots up but after 2 vibrations starts in normal mode. What do I do wrong? Does anybody know how to boot up into recovery?
Also, if anybody could suggest ways to get back to the speed and smoothness with older firmware versions?
Many thanks in advance and have a nice day! LJ

There is, I believe, a problem with the firmware on my Samsung Infuse phone that causes programs that have been installed, uninstalled, and installed again to be unable to save settings associated with the program. Is there a way to fix this without resorting to a hard reset? A hard reset is really a lot of work! Surely there is some way to fix this issue!
Try clearing Cache on CMW recovery.
To go into recovery:
If you are on a custom rom with extended power menu just select recovery then clear cache. Advanced clear dalvik cache.
If you are on stock rom or dont have extended power menum turn off the phone then hold volume up and down and hold also the power button, 5 second or so after the Samsung logo appears release the power button but keep vol up and down pressed then about 5 secs later release them also, that will get you to android recovery. Clear cache there.
or download a custom rom..
they're so much better then stock ROMS.
but i would think you'd have to do a reset.
use odin its not that much work you do like 4 clicks and you just wait 2 mins and your phones reset to stock again.

i'm not sure if i understood your problem correctly.
some programs may not install properly on the phone.
in those case, go to settings/manage application/
go to sd card and list them
try moving the trouble some ones to the phone.
if you do a reset on stock rom, take out the external sd card first or it will erase that too

Kyocera Rise soft bricked. Suggestions?

Hello everyone. I am an old member, seeing as I registered almost four years ago, but I guess either your database was refreshed and it lost my username, or I only lurked. So, as the title suggests I have one of those lowly, inexpensive, down right cheap Kyocera phones. Here is what I have figured out so far. I was able to root it using Kingroot. That went splendidly, though because of my over adventurousness I decided to swap some apps out. I added a new launcher to the /system/app folder and wanted to upgrade the com.android.settings.apk with one from a newer build. This phone (was) running Android 4.0.4 Kyocera release r77 build date 2013. Apparently Kyocera loves to lock the bootloader so if I was able to spin a custom system rom I wouldn't be able to flash it. Another thing which discovered was upon boot up the system checks the integrity of app the system apps. If one of them fails the check it will not boot the system fully. I was able to recover the stock boot/recovery/system roms from a thread on here, but I seem to be stuck in a soft brick loop. One thing that another thread said, the thread that had the rom images, it said that you could used ADB to flash the roms to the phone. Thing is, when I boot the phone it restarts, and if I put it into recovery mode (press and hold volume down plus power for ten to fifteen seconds) the only options I have are "reboot system now", "wipe data/factory reset", "wipe cache partition." There is no "flash update from sd card" or wipe dalvik cache option. As I have said before, I could try to flash the rom to it using adb but I believe that wiping the system partition unset the USB debugging setting. When I connect it to my computer windows device manager notices the kyocera removable device for a second then as the phone reboots it goes away. Setting it into recovery mode does not make it show up in windows. Is there any way I can flash the stock rom onto it? Any android sdk or adb trick I can use that can boot it into some recovery mode? I was trying to see if I can get it to boot into download mode but seeing as it has soft keys and not a physical home button I do not know if I can manage that. I was thinking that maybe they tied one of the physical keyboard buttons to the home button but I have yet to uncover that one. Any help would be appreciated.

Hi and thank you for using XDA Assist
If you can access your recovery it is already a good thing, try first to wipe data and see how it goes.

So, I boot into recovery and I do the wipe data/factory reset then the wipe cache partition for good measure and it still halts on boot. Same thing. Boot, kyocera logo, virgin mobile boot splash, then it halts where it would normally go into android. Then it reboots. Rinse repeat.
Any suggestions? I sorta need the information off the phone.

One plus One stuck in a reboot loop after cyanogen nightly update

So I haven't had any luck with my Oneplus One lately . I had rooted the phone and was running the CyanogenMod nightlies for a while, but recently for some reason when I updated it for Nov. 25 I have been suck in a reboot loop where the phone boots up and it starts updating apps, but then it continuously does this cycle of rebooting and updating apps. I have tried to enter recovery mode to try and remedy the situation as I have twrp, but for some reason it doesn't boot to recovery when I press down the power and vol down buttons. I have tried to adb to try and reboot into recovery mode but I haven't been able to get it to work. I'd really appreciate some help on this as I have no idea what to do at this point.
I should also mention that I would like to see if it is possible to recover my data as I foolishly did not make a back up.
Thanks in advance.
So just an update I was finally able to get into recovery mode. I backed up my data with twrp and I tried the method mentioned in the reddit link below.
http://https://www.reddit.com/r/AndroidQuestions/comments/1ly5b1/is_it_possible_to_restore_my_sms_from_a_twrp/
I installed the newest version of nightlies CM 13.0 2015 11/30 along with gapps 6.0, but now my phone just boots up and optimizes apps but when it restarts after that it just goes to a black screen.
I know I can wipe everything through twrp and install cm 13.0 probably eliminating the issues I am having, but I'm reluctant to do so as I would like to retrieve my sms messages. I have taken my photos off my phone so I have that.
If any one can advise me on if I can restore my sms from the twrp back up I have made then I'll wipe my phone and do a clean install.
Thanks in advance
i have the exact same problem. would be nice to have it fixed and working without losing all the data.
So I decided to go ahead and wipe my system as I have all of the data I could get out of my phone on my pc now. I get get cyanogen working nicely, until I go into twrp and try to restore the data files I had backed up. This goes well until the reboot then a message pops up saying something isn't working (too fast too read). I then get a blank screen.
Now I still have the same problem of how to put the data I had saved when I used twrp back on to my phone. I believe something in my data is corrupt which is why this is happening, but I'm not sure. Is there just a way to extract say the sms from the data I have saved, that's really all I need at this point. The backups made by twrp are in a format .WIN that I have never seen before and I would appreciate the help if someone can advise me what to do from here.
CM13.0 struck in Reboot loop

Thanks in advance

Are you pressing the Vol down button and power button. Also I unscrewed the back of the phone to unhook the battery cable then I pressed the buttons. I found also, through trial and error on my phone, that you can hold down the buttons for too long so you have to watch and make sure on that. I found that you should hold the 2 button combo through the oneplus one boot logo and you'll see the lights dim then you let the buttons go and its worked so far at least on my phone.

Issues flashing stock with odin J700t

I have a question, dont really know where to ask. I have the tmobile j700t, and I've tried restoring with odin, (with the j700t firmware of course) and im not sure if its doing everything. Everything seems to go fine in odin, flashes boot, modem, system etc. reboots, rebuilds cache, then it just goes to my original lock screen with my custom wallpaper and all my apps still on. I can do a factory reset after, but it doesnt seem to do anything but clear the cache. Am I missing something? I enables OEM UNLOCK and USB debugging before hand.
The inability to make write changes sounds like a bad NAND issue, you could try flashing with a .pit file but the phones internal memory could be physically damaged.

Try clicking the Nand erase all box and unclicking auto reboot. Flash the factory ROM and when it completes hold volume down, home and power buttons until the screen goes black. This is important, as soon as the download screen is gone you need to hold the recovery buttons (volume up, home and power) so the phone can erase all system data and update itself the way it's designed to after flashing a factory update. If the device reboots before you enter recovery you have to start over. Hit thanks if this helps bro.

well that seems to have fixed it, weird though, when I rebooted into recovery like you said, it did an update, there was a progress bar, then it rebooted, and rebooted AGAIN, did an "update" and then rebooted. Weird, I usually see it say "updating" but then it will stop and you can bring up the recovery menu. Never seen a progress bar and then it just reboot twice. Well anyway it seems to have worked so thank you!

Whenever you flash back to stock or update a stock firmware through official means, it automatically boots into recovery and erases the system you have in place, very similar to TWRP. If you try to flash a stock firmware without erasing everything you will always run into some kind of incompatible memory error. The screen you're thinking of is just the stock recovery checking your system and OTA's for an official upgrade. Glad I could help man.

Question Soft boot loop after wiping cache partition - Rooted S908E

I need help. After rooting the device and after several days of using it, and saw that Wipe cache partition can clean up stuff and increase battery life and performance. So I went ahead, connected my phone using a USB-C cable to PC, hold the UP button while booting, and selected Wipe cache partition. Booted it up again, and it was running fine but the phone has starting for almost like after every minute it hangs, and goes back to the Samsung logo, and the cycle repeats. I was only able to escape via booting in Safe Mode.
Any advice what to do to prevent the boot loop? Is there any way to know which or what makes the phone hang?
Running in Android 12 One UI 4.

Not sure why that would do that.. But it seems like the only solution now would do a complete factory reset and start over.
Thank you for the reply. For some reason, the phone just decided to fix itself. What I did was just let it be in Safe Mode for several hours, went back to Normal mode, and somehow it stopped hanging.
