Unable to enter Custom Recovery, Galaxy Pro 10.1 SM-T520 .Help Please, dead Robot

Hi all,
I have been hammering away at this one, and putting it on the back-burner, but now, it is really getting to me. Samsung Galaxy Tab Pro 10.1 SM-T520
It has been rooted with ODIN, and shows no problem, (things seem much easier now, as I have re-jigged lots of my old phones using so many more tools, I am not an expert, but can read and search without too much problems) I was very careful to choose the correct file, CF-Auto-Root-picassowifi-picassowifixx-smt520.zip, I have rechecked this step several times, as most of the instructions I found ODIN device ID:COM box should become yellow, when on newer versions it is blue I think, I wondered if I was going mad,
Root Checker Root access granted, all fine. I have Root access. n.
Installed CWM ,latest recovery for a Pro 10.1 wifi, recovery 6.0.3.1 Titanium backup-ed, all ready to go and Reboot and flash a new ROM.. No joy. .. Installed TWRP , same.
When it re-starts it ,shows the galaxy logo, flashes off, then back on, and then fails. Android dead with a red warning , standard recovery KOT49H.T520XXUANAE, all I can do is the usual options:apply update. The only thing I haven't tried is to just wipe all the data. I have a backup of my apps with Titanium Backup on the SD card,I am not that bothered really about much other data if its a pain. I just want control of my device and to try a new ,cleaner ROM(SMT520_GraveD_V3.0)
This has been bothering me for ages, I have read so many posts so am now getting really frustrated I have bought triangle away app. today although I think I sorted that issue early on anyway , but just in case...
Super SU seemed to have vanished so that is back installed
I think I searched and found the Mount/system issue and looked into an issue that lead me to the .system folder, but it is hidden, so I could not find the file it related to. I dont have the specifics to hand as I checked it out at work. I wondered if it is because I have ES file manager, not ASTRO as it said in some of the posts I found.but sure this is a red herring.
I have tried everything..I have a Mac at home and PC at work, I have tried ADB and can see &restart the device etc... so I am connected, first I got the error that it didn't recognise the sideload command. Read up on ADB , looked at the help etc. sideload isn't there as a command, very confusing. But I think I got there one I figured out paths, as of course they are different on a Mac, and possibly more so as I have 2 drives in it, which often confuses me ..grr.
I can of course get into the bootloader, with ON+VOL -, it tells me so far the system is : Official and Knox Warranty Void: 1 which I think is fine, but a chap at work suspected this, but after lots of threads I gather this is normal..
Sorry if long, just thought I should be as clear as possible. I have not really come across such an awkward issue as this , my HTC One was a breeze:crying:
*edit* Just worked out through trial and error, that to use the sideboot command I had to select send via ADB and now with the path /Desktop/SMT520_GraveD_V3.0.zip I was able to send the file but with the following messgae : E:footer is wrong and E:signature verification failed, twice.. So some progress
Thanks !

Just to say after being up waay too long on this, I discovered there is a newer firmware T520XXUANI1_T520BTUANI1_BTU which I may aswell upgrade to first, but of course I cannot do this OTA now As it recognises the device is 'tampered with' *sigh* so gun and games with Odin for Mac tonight, or JODIN3 , just to get the firmware upgrade(which seems to be a jungle of fake download links). before a Rom without bloatware..
I am also not completely clear why, as from another thread about KNOX, as I am basically running stock , without custom recovery.. According to this thread , but I am getting a bit confused now

however this is another story from the ROM install. Apologies

Well. No replies, but I did eventually solve this. Hopefully this can help someone. I am a tinkerer, but I really nearly gave up on this..But this was a cheap second hand tablet ( my first) and I want to see what it can do before I test drive one on my mother who is having nightmares with every Windows laptop I give her!
Once I got to a PC , I had access to Odin3, although it is not available online (apparently to Mac) I could not get it to work due to Java issues (JOdin3 online - brilliant idea but no joy for me so far)
I had the Rom I wanted ( GraveDigger- SMT520_GraveD_V3.0.zip ), the firmware update (T520XXUAOD2_T520BTUAOB1_BTU.zip(i think)) and the unlock file (CF-Auto-Root-picassowifi-picassowifixx-smt520.zip) , non of which I could install in any way , due to being locked out of using a custom Rom bootloader!
At this point I factory reset and cleared the cache( as that is the only options in the basic bootloader!) I also has ADB on the PC so attempted to install the files this way (after messing about using some software to produce the .tar and .md5 files needed for Odin. I tried everything to get this into proper 'bootloader mode' all from scrach again, including trying the adb oem unlockbootloader command, which I would never get to work as I could not get there!
With Odin, I was also again able to flash the firmware update, eventually, and of course had to unlock again. I was curious if I could now use the OTA update, and could not. At some point, in repeating this process( as I think it hung up several times and needed a hard reboot) I had at this point fully wiped the device as I know that is another reason to have glitches and an unstable ROM later.
I think I then tried to check and although T520XXUAOD2 seems to still be the firmware, at some point I managed to get online ( I think some superuser app which I have had to try several may have notified me that KNOX was reset:laugh:When I go to About>Software update it said I had the latest update! Good news!
At this point I had installed both CWM and TWRP again , and thought I would try TWRP.I had tried CWM and the same problem, like a double flash of the Samsung Logo , so I know it had reset !!
THIS TIME I used TWRP ( I thought of trying CWM touch, but its either paid, or I would have to find and ABD the file over I guess) , I managed to re-apply the Root file, Root checker confirmed this , as it had throughout this ordeal!, although apart from ACCESS GRANTED I dont really know what the rest means..Anyway although picassowifi , was still in Device name on TWRP I chose an earlier recovery version to install.- twp-2.7.0.0-picassowifi.img. When I re-booted, I was able to get the TWRP recover image, and install the ROM, I cannot remember if I re-rooted as I was so elated.
I had a few , freezing moments, reinstalling most of my apps through Titanium Backup, I think I just tried to reinstall everything which of was unnecessary, after a hard reset, all seems fine. I checked and the TWRP recovery seems to have stuck. I am not entirely sure how to check about the firmware , but for now I feel this is progress.
Good Luck if anyone found this any use.
Just to add, when you search this ( and probably many other models) you seem to get so many sites, offering exactly the same unlock information, in exactly the same way, many of the downloads seem to take you to many weird and wonderful places. So I tended to look here for downloads if possible. But I had to join SamMobile (which seems a useful site for the firmware upgrade) and trawl all over and assume similarities between other Samsung devices to fully check I was not being an idiot. But this was very odd and I could not find any posts or other workarounds that I did not try. But this new ROM feels lovely and smooth so far, and I now want to look into this tablet further

Stock TMobile D415 ROM D41520b_00.kdz Lollipop 5.0-- Can't root?

I'm a bit slow to realize this, but after updating to T mobile's latest 20b firmware (lollipop 5.0x), it lost root. I then tried to root it, using the three methods mentioned here: http://forum.xda-developers.com/showthread.php?t=2732311.
Towelroot clearly doesn't work anymore. The zip file in the above thread couldn't be flashed since there's no recovery operation possible (just showing an android with ! in a triangle sign). I also tried the purpledrake, but the script doesn't run when the phone is connected with all drives installed and adb devices showing the phone. I then tried to get fastboot mode back (to install twrp/cwm recovery to flash the zip file) by following http://forum.xda-developers.com/lg-l90/general/guide-fastboot-l90-d415-t2827825 which I have done successfully before, but then couldn't do it because it requires root (doh!).
So it seems that I just lost my ability to root, unless I downgrade to a stock kitkat (10e?) from tmobile, and then towelroot/etc. assume those work.
Anyone with experience on the stock 20b firmware? Can you root it and how? I'd love to use the beautiful 12.1 Cyanogen that's available here, but the camera doesn't work right on mine. Thus stock 5.0 seems to be the best option. Many thanks.

I got a bit further on the purpledrake method, in that I had to do a clean restart on the phone and connect to usb before the script will recognize. However, it ends up giving a really quick error message after trying a temp root: "your phone is not running a compatible software version. No vulnerable mode detected. Rebooting phone."
Anyway, many thanks to @brossovitch I followed http://highonandroid.com/android-smartphones/how-to-root-lg-g-flex-2-g2-g3-on-lollipop/ and it works like a charm. I can't seem to delete this very short thread so I thought I'd wrap it up with a solution. If it seems a bit useless please remove the thread (or tell me how to do it since I can't find the "easy button"). Thanks.

Help, moto x 2014 stuck in 'MOTO' logo

Hey, I have a moto X 2014 (xt1097)(brazil), unlocked bootloader,previously had root.
I updated to marshmallow about a month ago and had no problems whatsoever with it aside from the fact that root didn't already work for it.So yesterday I saw a post about a user that flashed the "SuperSU 2.62 v3" and got root, so I did the same but without flashing twrp(I just booted it)... It worked (sort of) but it was having some problem about a super su binary not working(I lost the screenshot).
With that I started searching for a way to make it work correctly, until I saw someone in a post saying that they wiped the phone and re-flashed the root file and it worked correctly, and that was what I did.. with one little difference I flashed the latest superSU file released (SuperSU-v2.64),but it didn't work, it initiated but there were notifications all the time about something not working(a lot of things).
With that in mind I started the same process I had done to flash the first superSU,wiped the data and cache, turned it on so that I could enable debug mode to start flashing the superSU but this time the phone didn't get out of the big `M` (powered by android) logo.
I seached a fix for it, on other posts people said that wiping everything(except system) and rebooting worked for them, but for me it didn't.
So I need help with this, if anyone can help please do so, thank you.
UPDATE: I just remembered that before that I didn't use the "unroot" function in the superSU version that didn't work, so I think that I got bootloop because of that, but I still don't know what to do.

Moto X always boots into recovery unless I manually choose normal startup each time

I rooted my XT1052 straight after updating to 5.1, a few years back. As a result I have never been able to install the OTA update (the one which fixed Stagefright, so far as I'm aware it's the only OTA Moto did after the 5.1 update.)
I've been unable to install a few apps recently due to SafetyCheck failing on the rooted phone, so yesterday I decided I would unroot and return to stock, which would also enable me to install the bugfix OTA. (And with Magisk, nowadays we can keep root access without a modified system partition.)
I didn't have a stock image (or I had an image of some sort on a hard drive but couldn't remember its provenance). Moto's download page has images for the XT1053 but not the XT1052… Eventually I found firmware.center, where (I thought) I found the right image.
However, when flashed it (following the step-by-step guides which are the same on various pages, including Moto's own instructions), it failed to flash the `system` image. I got messages about invalid block sizes (IIRC) and then an error saying the image was corrupt (it wasn't; I checked the MD5).
This left me unable to boot. So I downloaded LineageOS (I'd been considering switching to LineageOS anyway to get Android 6), and was able to flash it from TWRP without any issues (other than the fact that a newer version of TWRP is required than the one published on their website…)
All well and good – except that now, when I turn my phone on it goes straight into Recovery (TWRP). Initially I could only get System to boot by starting the bootloader (Pwr+VolDn) and selecting 'BP Tools', which would cause it to boot normally. (I found this by trial and error.) Now, after re-flashing the boot image, It also works if I select Standard Boot from the bootloader. But I still have to select it manually. If I just turn the phone on normally, with the power button, it always boots into Recovery. Also, all the 'reboot' options from fastboot/adb or TWRP all boot to Recovery.
Now, I think I know what I did wrong. The stock image I downloaded was 'XT1052_GHOST_RETGB_5.1_LPAS23.12-15.5-1_cid7_CFC.xml.zip', but my system version before was 5.1_LPA23.12-15.5. I just assumed that the 5.1_LPAS23.12-15.5-1 version was a minor update – likely with the Stagefright OTA installed – so I went for that. But probably I should have gone for the exact version I already had installed.
Searching these forums and the wider web, I haven't found anyone with the exact same issue. But from similar issues, I decided I needed to re-flash the partition table (gpt.bin). I took the gpt.bin image from an older 5.1 ghost ROM I had saved, but I'm not able to flash it – the bootloader shows security warnings when I try.
So I'm stuck now – I have tried pretty much everything I can think of.
If anyone has any ideas I'd be very grateful!

I have the same problem, my moto x only boot in recovery mode.
Did you get any solutions?

No :'(
I think our phone is old enough now that not enough people use it any more to find solutions to problems like these.
It's sad, I don't want to upgrade, I've never seen a phone I like as much as my Moto X.

Help MotoG5+ root no camera

First of all, sorry if I'm writing to a wrong forum or thread, it's very difficult to find anything on this forum...
I really need help with my device as I've tried everything available on the Internet and haven't got the desired result.
My device is Motorola Moto G5 Plus XT1685 (Spain) bought from Amazon in December.
I want to root it.
First try failed, and the device got bricked (or whatever you call it, the system was erased).
So I installed this:
POTTER_RETAIL_7.0_NPN25.137-92_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
The system worked normally.
I proceeded with the instructions given on the internet: unlock, flash twrp, format data, flash boot, install the wifi patch, install SuperSu.
Great, it worked, the system loaded, the device was unlocked. BUT! The camera didn't work. I've tried all the solutions offered on the Internet, I really did. I re-rooted it again and found that the camera goes wrong with the boot kernel image.
So I used the image from the aforementioned potter pack. It went well, device rooted, camera works. But there is no wifi modem. Yes, I installed the wifi patch, several times, from the recovery mode.
So, it's either camera and wifi or root... Is there any solution for moto g5 plus xt1685 to have root AND camera and wifi?
Thank you.

PS: Magisk didn't work at all.

You're right - posting in the wrong forum. Your question belongs here which is where the expertise resides for your device. This is not a SuperSU issue.

How can I ask for help? I cannot post anything on that forum, the system doesn't let me.

General and Help sections are open to all; developer/development sections are restricted. As is the case with most device centric forums on XDA.
