[Q] n900w8 Won't boot into recovery mode

A few months ago I rooted my N900w8, installed custom recovery (cwm), and flashed Android L. Today I tried to update the recovery, planning on updating the ROM as well. But now no custom recovery works at all, even the one I had running before. When trying to boot into recovery it says booting recovery... like it should, and then the screen just goes blank, then the phone restarts. Sometimes getting stuck in a bootloop trying to boot to recovery, but usually just regularly booting and boots normally to Android L. So now I am unable to update my ROM because not a single custom recovery has worked and therefore I cant flash the .img files. Please Help!

I had the same issue except when I try to load recovery it would "forward" itself to download mode.
This may work for you, try re-flashing the latest CWM update with Odin. Place your phone in download mode by powering it off and holding Volume Down + Home + Power. Press volume up to proceed.
1. Download and extract
2. Run Odin as Administrator (Download if you don't have already)
3. Select CMW file from your download folder and place it in the "AP" section.
4. Start
When finished, Reboot holding Volume UP + Menu + Power Button. Vola!
Let me know if this works for you.

Yeah depending on which recovery I flash it'll either forward to download mode, get stuck in a boot loop trying to start recovery, or restart and load the ROM.
Unfortunately it still isn't working :/ I used the tool from this page (http://forum.xda-developers.com/showthread.php?t=2446269) to convert the .img to a flashable odin file. Used the proper Canadian touch recovery (also tried recovery without touch) from this page (https://www.clockworkmod.com/rommanager) and no luck. Tried to enter recovery mode, it says entering recovery mode, goes black for a few seconds, vibrates then restarts the phone in regular boot mode :/ Any more idea's?
Do I need to be flashing a recovery that supports Android 5.0.2 for it to work? Im so puzzled.

YES!! Finally I was able to get a TWRP 2.8.5.0 working. Downloaded latest version from the main TWRP site and flashed using ODIN, did not use the converting tool above, downloaded the TWRP as a .tar flashable file from their site. Thanks for the help!
Do I need to close this thread or anything? This is my first time posting on xda

Congratulations on solving your own problem! ^_^
I just figured to share my part when i experienced the same issue. I feel like it has somehow corrupt itself after it finished flashing which results in an empty directory for the recovery mode.

Samsung Galaxy S5 SM-G900F No Recovery Mode always restart Brick

Hello,
I´ve got a problem with my Samsung Galaxy S5
The History:
I bought a Samsung Galaxy S5 SM-G900f from Ebay with a Software Problem. The seller said, he try to flash a Custom Room like Cyanogenmod, he don´t know which)
The flash failed (i don´t know why). Now the S5 have a brick.
I tried so much, but i can´t repair it, pls help me.
The Problem is:
I can not start the Recovery Menü to flash a new Custom room. Always i tried to start the Menü, there is just a text "recovery Booting", then the phone restarts after round about 10 sec.
So even if i tried to start the S5 normally without recovery Menü, it´s just the Samsung Galaxy S5 Logo power by Android, then the phone restarts all the time.
The only thing i can do is start the download mode.
Things i tried:
- Firmware installation about Kies (pass, but still the Same Problem)
-Firmware Installation about Odin (pass, but still the same Problem)
- CF-Autoroot flashing (pass) then i tried to flash a recovery like PhilZ but then when i tried to open the recovery it`s "Recovery is not seandroid enforcing" Set Warranty bit
I tried so many firmwares but still the same Problem. Now it is installed Lollipop 5.0 G900FXXU1BOI3_G900FDBT1BOI1_G900FXXU1BOI3_HOME
There is no chance to repair it over ADB oder Fastboot, cause USB-debugging is disabled
Maybe you can help me and help me to stop spend all my time for this phone, cause im interested to know how i can repair it.

With some of the newer LP based firmwares, twrp 2.8.7.0 klte is the only version that works.....
Other than that, you might find it necessary to odin back to KitKat (flashing a pit file too) and try 'towelrooting' your device.......
BE WARNED.......If you *do* flash a pit file, make sure it's the CORRECT pit for your device.....In some cases, flashing the wrong pit will permanently kill a device.
http://i.imgur.com/rVnFwJM.jpg

So i had try it.
1.)hold on ( volume up and home) then do not release until recovery mode boot
--> The phone always restart no recovery is possible
2.) I try to install on LP the TWRP 2.8.7.0 Still the Same error "recovery is not seandroid enforce" Set Warranty bit: recovery
Before i root the device with CF-Autoroot and it´s pass
3.) I downgrade to 4.4.2 with a full package of Firmware with CSC,BL,AP,CP and a pit file.
The downgrade pass, when the phone starts it says recovery booting in blue script, then the phone restarts. I can´t intstall towelroot, cause the system is not booting, so i´d tried to install CF-Autoroot (pass) and then also the TWRP 2.7.0.0 pass but not booting and then 2.8.0.0.
But still the same "recovery is not seandroid enforce" Set Warranty bit: recovery

If you got a pass on your KK flash, you have a stock recovery......
Have you tried booting into that recovery and wiping cache and factory resetting? It is necessary to do this when downgrading......
http://i.imgur.com/rVnFwJM.jpg

Yes it was a KK stock recovery.
I tried to boot in this recovery, but when the phone starts it says recovery booting in blue script, then the phone restarts after a few seconds.
It´s not possible to wipe cache or make a factory reset, cause the recovery is not booting. That´s my problem. Also when i have flash the stock firmware i tried to go into the recovery but when the phone starts it says recovery booting in blue script, then the phone restarts after a few seconds. ( 4.4.2 and 5.0)
I´can´t flash a custom rom cause the recovery is not booting. I´ve no idea

Are you attempting the 3 button combination from powered off to get into recovery?........
@'detection' does the OP's situation sound familiar?.....
http://i.imgur.com/rVnFwJM.jpg

Very familiar -
https://dl.twrp.me/klte/
Flash TWRP 2.8.7.0 .TAR (Do not unzip) with ODIN 3.10.7 - in Download mode (Volume Down & Home & Power)
It will say "recovery is not seandroid enforce" Set Warranty bit" at the top when you boot into recovery, give it a few seconds and you should see the TWRP blue splash screen, and then recovery should load up
Then flash a custom ROM from TWRP
--
If that all still fails, try flashing the PIT file for the G900F along with a Stock ROM
http://forum.xda-developers.com/attachment.php?attachmentid=2721101&d=1399024091
Extract this one so it is .PIT, and add it to ODINs PIT section
If that still fails, try flashing just the PIT file with ODIN, and then the TWRP 2.8.7.0 with ODIN and see if you can get in that way
Or PIT and TWRP together
Try a combination until you get back in
Also try different versions of TWRP from 3.07 up to 3.10.7

It sounds familiar because it's happened to many other people recently too, although TWRP usually fixes it
Follow my instructions above

No chance guys,
i´d tried to install all TWRP which i found once in 5.0 and also i tried to install on 4.4.2. But always the same mistake. (recovery is not se.....)
Now i´ve tried to install CWM-Recovery and now there is no mistake like upside. Now in blue "recovery booting" and in yellow set warranty bit: recovery
But the recovery is not booting, the phone always make a restart. I´d also tried to install the recovery without auto-reboot in odin. But no help.
I don´t understand, cause when i flash a Stock Firmware, the recovery menu ,in my opinion, it have to start, but it doesn´t. Maybe i have anexpensive paper weight now
I search the internet to install a Custom room over Odin, but i don´t find any results, so i think it is not possible.
Do you have more ideas? Pls help. Thanks

I have the exact same problem, some are calling it the Black Screen of Death (with the blue led flicker). This is what happened to me:
0) had TWRP + latest 12.1 Cyanogenmod
1) installed the alpha 13 Cyanogenmod, which worked, more-or-less...
2) lost access to TWRP recovery, did not lose access to download
3) tried every single type of black magic from XDA (Kies, pit files, bootloader files, etc)
4) now it turns on, the LED turns blue and slowly, slowly flickers, but the screen is blank. At some point it plays the Samsung boot sound
Any help will be enormously appreciated.

Ithink you should try re instal original firmware using odin and get ur warranty back then fix it on samsung

I found a trick that seems to help slightly, until an actual solution is published. During a misbehave episode, assuming that something shows up (which is not always the case):
1) press <power + home + vol-down> until the download thing shows up
2) press <up-arrow> so that it actually gets into download mode
3) press <power> until the screen turns off and immediately release (otherwise it will try to reboot); this makes it stay off
4) let it "rest" for a certain period of time (could be 5 minutes or more)
5) back to normal

Did u root your device vai CF auto root? Did it work?

Can't flash twrp/Can't root?

Hello. I've been following every guide I can on flashing TWRP and rooting the Galaxy Tab 4 SM-T230NU, and none of them are working. Basically, Odin will flash the recovery, I'll prevent it from booting into Android by holding Power + Vol Up + Home, but what happens is I'll see a split second glimpse of the TWRP logo, but it goes black and reboots into android anyway. Can somebody give me an updated tutorial, possibly with the latest files, so I can flash TWRP & Root my Galaxy Tab 4 SM-T230NU?

Did you tried both with older TWRP. That method should still work and it is up-to-date because this tab is very old. I think I got TWRP for my device other way, can't remember any details but I've only used info from this forum and overall it was something like this:
1. Root with Kingoroot (might have been other weird onclick root thingy)
2. Somewhere in forum was a TWRP files that were able to be "installed" by just copying them in right folder (no idea where to get files or what the folder was and haven't done this way for any another device)

I have the Sm T230NU Nook version. I've attempted the flash following every last detail in the instructions. Odin always says "successful".
Have tried 5 different TWRP versions and several Odin versions and can never get it to boot into the TWRP recovery - it keeps going straight to the default Android recovery. I never even see a glimpse of the TWRP screen either. Any recommendations?

S5 G900I Recovery Bootloop - Cannot get into any recovery mode?

Hi All,
Got a S5 G900I here that's doing my head in! Stuck in the infamous bootloop at the Samsung logo.
I have been a long time reader of these forums and have prior experience from flashing Samsung phones but this one is driving me mad!
I can put the phone into Download mode without an issue, phone is detected in Odin and I can flash any firmware I try to it (Have tried original 4.4.2 , 5.0 and latest 6.0.1 firmwares from SamMobile). Odin goes through the entire process, reports as "Pass" but then the device goes straight back into the reboot loop and will never fully boot up.
I can also use Odin to push TWRP / CWM / PhilzTouch recoveries, however the device will never boot into the recovery partition. I get the blue "Recovery Booting" message briefly, then the device bootloops again.
Does anyone have any further suggestions to try and get this phone operational again?
I have tried multiple versions of Odin, multiple firmware versions, different computers, different USB cables, different USB ports etc.
I look forward to hearing back from you

Try this :
1. Make sure flash latest recovery with latest ODIN version. Check the official website.
2. Do not let your phone restart after flash recovery with ODIN. Un-check auto reboot on option tab in ODIN. After PASS flash recovery disconnect USB cable then ummm ... I do not know what about your phone .. Mine G900D, I just just pull the battery then I plug it again lol ..: D
3. It should be able to get into recovery after that. If not, it means the recovery type does not match your phone.

It is important to turn off the phone right after flash recovery on the download screen. I mean really off rather than reboot. unplug the battery do not turn off with the power button. Because when rebooted, recovery will automatically return to stock .. so the recovery you just installed will be erased again. if stock recovery inside is broken you will get bootloop. if it is done and still can not enter recovery .. huum .. I am afraid if it's a hardware problem .. because it's easier to find a suitable recovery than its firmware. if recovery can not be in flash .... it's a long way to go ..
By the way, sorry for ask .. you release the power button when it says "recovery booting" with blue text.. right ..? while continuing to hold the volume up..?

Thanks for the quick reply.
Yes when I am booting into recovery mode and can see the blue text "Recovery Booting" in the corner of the screen I let go of the power button - device still boot loops.
Have flashed recovery then removed battery - still cannot get it into recovery.
I have seen some Samsungs have hardware issues with their NAND chips but in these cases there are a lot of errors relating to NAND displayed on the screen when I've seen it be a hardware issue. None of these appear on this phone - convinced it has something to do with software.
I found these threads - exactly the same issue as me, and at the end it says they fixed it by flashing a specific bootloader however I have a G900I and the phone in this thread was a G900F

No recovery or download on SM-T500

Seems I found a way to semi brick my SM-T500. I was attempting to install the LOS 18.1 ROM just posted in the guide section. Some how I got the "can only install official" error message on my download screen after flashing TWRP. Made the mistake of flashing only the stock AP without BL or CSC and now I can't get into either recovery or download modes. Holding vol up and down and plugging in USB cable does nothing. Same with holding power button and either vol up or down. Blank screen. Can only power on and boot to system.

Did you install twrp and can you get into recovery. I had similar problem but was still able to get into download mode from power off. However to do so I had to boot into twrp and select reboot and power off... from that menu you can also boot directly to download mode... I know that doesnt halp much if you hadnt installed twrp yet... but thought I would throw that out there...

I can't boot TWRP or download. The only thing that will boot is system. Can't even get to the lock/unlock screen.

can you connect to adb shell? and try #reboot download
or #reboot twrp. I figure if you get to download you can reflash stock and start over.
Also when your trying to boot into recovery try not being plugged in. Not sure about this device but a lot of older Samsung's that I had would not let me get into recovery if I was plugged in during boot.

Locked oem mode
Locked download mode
Locked wipe factory
Locked update from sd card
Recycling item...
Need factory reset

I saw alot of issues with twrp so I tried Magick for first time ever on my SM-T500 and had a minor hiccup bc I wasn't paying attention to firmware and installed an old AP with newer firmware but ended up just reflashing the whole tablet with the same firmware as the AP that is required for Root and presto it worked! AND HEY IM DEF A NEWBIE!

Yeah I've run into the same thing, I originally missed the step to run Magisk after I flashed the patched tar and rebooted into the System and it triggered the "Prenormal KG state" problems. Finally I managed to flash stock ROM back and got to exactly where you are now.
I was able to just flash the patched Magisk AP without CSC and BL, and now it will only go to stock recovery and was able to get TWRP to work once but couldn't factory reset or wipe cache due to (which I assume was) a ton of mounting failures when it loaded.
Anyone else have suggestions to get this thing stable so I can flash LOS? I can get to Download mode.

hello, I post this because it's seems the same subject. I have to password protected (forget password) original rom tablet (non root). For me the datas are not important , I just want to remove the password or reflash with original rom. I downloaded Odin , usb driver and correct firmware. I select AP firmware with Odin, I see the connexion (COM3 green) and it's stuck to "setup connexion".
My problem is that it's impossible to enter in download mode.
When I try to shutdown the tablet, it ask me for a password.
When I press for seconds the power button , after few second I see the Samsung Logo and the tablet restarts.
I try to press volume up, volume up and volume down etc...but each combinaison...no recover, no download mode, nothing and impossible to flash . is it normal ? how to do to unsticked SetupConnetion ?
regards
bruno

This is not the same as my problem. My problem is that I flashed AP without BL and the two don't match. It isn't that things are locked but that I can't boot to anything but system. Can't boot recovery or download so I can't flash ANYTHING. Not even stock.
