I followed the instructions here http://forum.xda-developers.com/verizon-galaxy-s5/development/safestrap-odin-safestrap-flashable-t3161043 to install Safestrap on my phone with rooted BOE1, my phone rebooted, and I'm looking at a screen that say Android System Recovery <3e> LRX21T.G900VVRU2BOE1
I was trying to install the MOAR rom, but I fear that now I'm stuck in this strange recovery with no way out. Could someone please tell me exactly what I will need to do to get out, and possibly how to actually boot to Safestrap?
Not to leave anything out, though I'll look the fool if I don't, while in this recovery I wiped Data+Cache and attempted to install the ROM, got some sort of error about footers and signature verification (it happened pretty quick then rebooted) and wound up back in recovery, so I tried flashing the BOE1 kernel, same problem, back to recovery.

S5 doesn't have a custom recovery per se, so any app that "reboots to recovery" will go to the Android stock recovery which your in. You can't flash anything of value in there, and can't install a custom recovery. You should just be able to turn the phone off then on again to get back to the stock rom, right?
It's been so long since I've done it, but won't safestrap only install on kitkat? Doors it even work in lollipop? Must people use flashfire I think
I should probably mention now that I got it fixed. Following more instructions in that thread, I did everything in the order of the first step again, using ODIN, flashed back to NC2 (I think? Going off memory) rooted, installed Safestrap, flashed MOAR, and the OC4 firmware, and here I am.
I bought this phone used and the person who had it before me it rooted and installed some of different ROMs on it. After getting my used moto x pure 2015 running android 6.0. I booted it up and tested all the functions (including downloading a few apps) Wi-Fi, camera, audio/charging jacks ext. Everything worked fine. So did normal factory reset (not using TWRP) just to make sure everything was clean before using it as my daily. Then, (BUM BUM BUM!) when I tried to start downloading all my apps. None of them would download even though the Wi-Fi was working. Error 492 I think.
I started trying custom ROMs because I was having two big issues (apps not downloading and incoming call not bringing up accept/decline screen) with my stock rom. and wanted to fix those issues with a fresh stock image.
This is all new to me and has not been as easy as anticipated. If anyone knows a clean factory image I could flash or a fail proof fix to error 492 that would be helpful. I really just want to return to fully working Motorola stock android, but the files I have used haven’t fixed the issue. I have searched for a factory image without finding one…
Is there a way to flash the Motorola image through TRWP?
Otherwise, maybe you can help me with my flashing method, and maybe tell me what I am doing wrong. I tried to flash multiple stock images all with the same issue. I have also tried to flash Resurrection Remix, and Brocken OS, both having resulted in a bootloop. I am starting to think I have done something wrong. The steps I have taken so far have been these:
My bootloader is unlocked status code 3.
My phone is not rooted. Do I need root?
First I downloaded adb and fastboot.
Then I flashed TWRP (3.0.2).
I never installed the official Motorola stock image because flashing it from fast boot wouldn’t work and it couldn’t be flashed with TWRP because it is a .gz not a .zip. (I knew a .gz needs to be flashed with fastboot but I knew TWRP was easer so I didn’t fuss with it)
After flashing TWRP to my phone, I downloaded (yes, I checked the md5) the various ROMs to my computer then transfered them to my phone via micro SD card.
Here are the file’s names if that matters:
moto_x_pure_edition_stock_x1575_mphs24.49-18-3_v1-odexed
(booted and Wi-Fi but play store won’t download apps)
moto_x_pure_edition_stock_x1575_mph24.49-18_v1-odexed
(booted but no Wi-Fi)
Broken-v4.9.1-clark-6.0.1-OFFICIAL-20160824 (with Broken_gapps_lp5.1.x_09172015)
(Brocken was the only non-stock that got past boot, but I still couldn’t get past set up without an error and never made it to the system.)
ResurrectionRemix-N-v5.8.0-20161220-clark (7.1 gapps failed to flash but I booted it anyway.)
(boot loop after both of my tries)
I got Wi-Fi working on one of the above stock ROMs (so I KNOW it works) but couldn’t even turn Wi-Fi on in all the others.
The method I used to flash all of the above files in TWRP was:
Wipe
Full wipe (davlik cache, data, system, cache)
(used for RR and Brocken)
Factory reset (using TWRP) (davlik cache, data , cache)
Used for the stock ROMs or even after flashing .zip file I got the error: no OS installed.
Install
Select file of ROM flash (gapps if needed) and flash
I can’t remember which ones but on some of them after flashing I again did a factory reset.
Then I rebooted
Thanks for reading. Sorry it was so long. I tried to add as much useful information as possible. Hopefully someone smarter than me will see my error(s) and help me get my phone into fully working order.

I'm having a similar issue. Tried the TruPure rom but I want to switch back to stock. If I do a full wipe, would I be able to use the files that Motorola provides on their website and flash those throught fastboot? Or through TWRP? Any chance you have a link to a guide on how to do the latter option (installing through TWRP)? I'm just trying to get my device back to 100% stock so that I can receive OTA.

Thank you for sharing that link. I think I get it but it seems too easy considering what I've tried so far. Just to make sure I get it:
I should download the odexed rom, go to twrp and wipe data, cache and dalvik then flash the odexed rom through the install function? And thats it? I've literally tried a ton of stuff so if this takes care of it, this is great!

Yes, also wipe system, make a backup before If you want, but remember, for the OTAs support you need yo flash the stock recovery via fastboot. Good luck.

This got me back to stock! You are the real MVP.
So I remember seeing a recovery.img file in the factory image that motorola posted on its site. Does it have to be a specific stock recovery or do I need a specific one to match with the file I just installed?
thanks again

So I'm on stock build 49-18-8 and flashed the recovery from 49-18-3. I went into fastboot and selected recovery. I got the android character with an !
I then did the power button and volume up and got into stock android recovery. Am I supposed to see the android character with ! each time I try to reach the recovery menu? Just wondering if I did this correctly.
Thanks again for pointing me to these resources!

Yes.
So I got my 6GB/64GB x720 yesterday. It had Google Play Store already installed (ordered it from HonorBuy) and asked me to install a 7MB OTA, so it seems it had a recent version of EUI on it. My idea was to put LineageOS 14.1 on it or if it wasn't stable enough for me, at least a debloated and rooted stock. So searched XDA and followed this HowTo. No Errors, flashboot oem device-info said, bootloader unlocked, perfekt. Installed TWRP, downloaded recent LineageOS and followed the guides to flash (wipe, ...). Unfortunately flashing never finished, I always had a full progress-bar and it stayed there without doing anything (ok, the device got hot). Thinking of a broken download, I redownloaded the ROM but same problem. So I started downloading other ROMs from XDA: Resurection Remix and OmniROM. Flashing-process went thru, but couldn't flash gapps and ROMs didn't boot at all. I was always only getting to the LeEco-Bootlogo with the chinese writings. So next thought was, maybe for some reason I can't install Lineage-based ROMs, let's figure out later and get a debloated stock ROM. So I downloaded MAURO V2.2_Free and gave it another try. Looked more promising, as the bootlogo was a little different, no more chinese writing but english. Unfortunately this was all I could see of MAURO as I only got a bootloop... so again reflashed MAURO and this time a single line in TWRP-output came to my eye "boot.img could not be written". I checked flashboot oem device-info after every flash and it always told me, bootloader is unlocked, but there seems to be something else that I'm missing that obviously still keeps the bootloader locked. I wiped the phone several times, even sdcard... nothing helped. The only method that worked for me to get a working rom running was by this guide, manualy flashing every bit of stock ROM with flashboot. With MAURO-ROM, I also tried to flash boot.img manually with flashboot, but that didn't work, either.
Anyone of you experienced the same? What am I missing? Or is this some new protection implemented by LeEco for the most recent devices? Any help really appreciated!

I have the same phone from Honorbuy, I flashed twrp using the tool by Mauronofrio and from the twrp wiped all and flashed the custom rom, all went ok, no errors at all! Glad to see you have solved anyway!
Thanks for the answer... no, it's not solved for me... still a lot of bloat on the phone I can't get rid of. Do you have a link for the tool you mentioned? Could be worth a try...
Hi! I've used this tool installing it on a Windows 7 64 system:
https://forum.xda-developers.com/le-pro3/development/tool-tool-one-mauronofrio-t3580611
Then turned ON the (original LeEco stock rom) usb debug option by the rom's developer options, then downloaded the LineageOS 14.1 by Team Superluminal in the phone's internal SD (the only SD it have!) + Arm64 nano Gapps, then with the tool gave a reboot in sideload mode. Then flashed the twrp recovery by the tool, restarted in recovery mode then executed a backup of ALL the "backupable" stuff (all the original rom and data and efs), then in wipe/advanced options I wiped dalvik, system, cache, data. Then in Advanced/file manager I wiped all the SD files with a dot ( . ) at the beginning of their names, then flashed the custom rom + gapps, reboot system, wait some minutes, done!
No luck with this tool, it doesn't even find my device. Any other ideas? I've read something for the x727, where they had to flash a 19s bootloader first, but I don't want to fiddle with flashing files that are not 100% meant for the x720...
CDFS
Solved! As I could install TWRP I just went the next step and installed SuperSU (rooted the phone) in order to at least debloat stock rom. During the installation of SuperSU I saw, that SuperSU obviously patches somehow the bootloader. After checking that SuperSU worked in the ROM, I was curious if this could be the missing part I was searching for. I tried to install a LineageOS-based ROM and BINGO! it just went straight through! From my previous phones I was used to just install TWRP, wipe anything and flash desired ROM. This seems to be different on this device... so the proper procedure to be able to flash any ROMs is: Install TWRP, root stock ROM, reboot so SuperSU is fully functional, then go back into TWRP, wipe, flash what you want.
CDFS
I hate to say it, but it's still not solved. After testing Resurrection Remix, I wanted to test turbos ROMs, so went to TWRP, wiped and flashed... and got the same behaviour as before, ROM not booting. Also installing SuperSU via TWRP again didn't help, so brought back the phone to stock 023S manualy with the guide by Presterin, installed TWRP again and also SuperSU. No Errors, but flashing a different ROM didn't worked. So for now I'm back to stock, rooted it and tried to debloat it by myself. The only difference between the successful flashing and the failed was the stock version: I had the 026S-update when I rooted the phone and successfuly could flash another ROM. My guess would be that LeEco changed something in the bootloader, but I have no chance to verify this. Anyone from the devs maybe who could look into this? If you need dumos, logs or anything like that, I would be happy to help.
CDFS
This seems unrelated to bootloader.
Anyway:
1. Make sure you got the latest firmware, if not sure:
1.1. Download latest OFFICIAL ROM
1.2. Rename the rom to a 'update.zip' and place it on phone's root directory.
1.3. Reboot to fastboot and flash STOCK RECOVERY
1.4. Reboot to recovery and flash, also check wipe data.
DO NOT FLASH STOCK ROM WITH TWRP! THIS WILL NOT WORK!
That's it, you should have the latest firmware now.
After booting to stock rom, reboot a few times is recommended.
2. Download latest OFFICIAL TWRP
2.1. Flash TWRP with fastboot.
2.2. Reboot to TWRP.
2.3. Download any custom rom of your choice.
2.4. Wipe.
2.5 Flash.
Done.
You can try to flash a stock, old rom using the "Qfil/FlashOne" way as suggested by Tryzex (read his thread and other related threads), then once you have got a stable, full working phone, you can (hopefully!) wait for a LeEco OTA automatic update that can "repair" the file system/partition structure (also bootloader I hope!).
Btw, to debloat it isn't necessary to root the phone, you can keep the phone unrooted & debloated using the file manager embedded in twrp recovery to delete/replace any file/app you want. I'm sorry I can't help you better, cheers and... good luck!
PS
I see now the post from Voron00, it's a good hint!
@voron00 thx for the steps described. I'm using the most recent, official TWRP (3.1.1). Latest Official Stock seems to be 023S on their site, even though there is a 026S update. However, I did this 026S-update and rooted again, but was to cusious if flashing would work now... so I tried flashing turbos MIUI... guess what? It worked. So for whatever reason I seem to have trouble when flashing from a 023S, but no problems when flashing from 026S. I don't quite understand why you think that my problem is not related to the bootloader? As mentioned in the OP, I could see in the logs that while flashing, some roms had thrown errors regarding writing the bootpartition.
CDFS
Seems as I found the culprit, somehow. At least I could flash two other ROMs without any problems. Obviously I mixed and partly missinterpreted some steps found in different threads and howtos. I had "rm -rf for formating" ticked all the time in TWRP. My flashing procedure is now as follows:
1. in TWRP settings check that "rm -rf instead of format" is NOT ticked
2. wipe Cache, System and Data
3. repair filesystem for Cache, System and Data and check that no errors occur
4. in TWRP settings tick "rm -rf instead of format"
5. flash ROM
6. wipe Dalvik
CDFS
"rm -rf" clears all the files and directories without formatting the partition. If your partition is damaged you need a real format to obtain a reliable partition (if the "disk" isn't faulty). Perhaps in your case a real format was required to solve the problem! I always used the real format and assumed other users even so. I see you finally solved the problem!
I tried to factory reset a custom ROM, got sent to TWRP then I can't reboot to system from there. Tried a clean install but to no avail. I've looked around on the internet and I think I have to reinstall stock ROM and then reinstall custom recovery and ROM, except if I were to install the stock ROM once again (with sp tools) I need my phone to be turned off, not in recovery mode. So how exactly should I proceed now?
EDIT: Managed to get rid of the TWRP bootloop by restoring from a stock nandroid I've found on the forums, coupled with flashing a stock recovery image using TWRP. Reunlocked bootloader, flashed TWRP all over again and then flashed custom ROM and Gapps. Everything running fine now.
Mods feel free to delete this post since it's solved itself, or leave it in case anyone needed help concerning the same issue, up to you.
Hi
Bibi if you’re still active on xda reply to this

can you put a link where you find the stock recovery, cos i've restore stock recovery on twrp but my device keep booting to twrp
Hi friends! I really feel frustrated with this phone.
I began by using fastboot to flash TWRP (twrp-3.1.1-1-s2), used it to flash Lineageos 13.0, but IR BLASTER doesn't work, then I flashed 14.1 and IR blaster, Sim detection, flashlight and camera don't work correctly, I tried Resurrection remix and MIUI8 too but I gave up, neither of those Custom Roms works as I wanted them to.
So I went back to EUI and all was well until I wanted to update OTA, it gave me an error every time, tried to do it with update.zip but nothing, using stock recovery and nothing. I used TWRP and wipe everything again, now this thing won't start it just bootloops, I tried everything for two days and every time I use a stock ROM (5.8.020s) it gives me an error, or tells me it can't be read. When I factory reset and format everything it tells me I dont have an OS installed, so I'm completely lost I don't know what else to do and I can't return the phone because I'm overseas right now.
I really need to have it as when I got it the first time because at least it was functional but I just can't get it to work
I could really use some help right now :crying: thanks in advance guys!

So I managed to fix the problem. When you root this phone or in fact just flash a custom recovery like TWRP, it changes the model of the phone, If you unroot the phone you won't be able to receive OTAs anymore even if you are on stock ROM, you'll always get an error at the end of the update even if you do it manually, if you are dumb like me and didn't make a backup of your stock system, you won't find any help on the internet more than to install a custom ROM and learn to live with the errors and bugs. I did not want that so to be able to get the phone to its factory state, what I did was this:
1. Download: stock recovery image for Le s3 x522 (official, you can find it anywhere), LeEco_X522_5.8.019S_OTA.zip, bootloader-20S-s2.zip, twrp_s3.img (the chinese TWRP recovery) and S2_X522-NA-OP-IFXNAOP5802102141S-5.8.021S.zip
2. Save those zips to the root of the phone, obviously the .img files you are going to flash them through your PC
3. Put the phone in bootloader mode. command: fastboot flash recovery recovery.img (the official recovery)
4. fastboot boot twrp (the chinese one)
5. From this step what I did was pure luck
6. wipe cache and dalvik and install LeEco_X522_5.8.019S_OTA.zip
7. wipe cache and dalvik and install bootloader-20S-s2.zip
8. wipe cache and dalvik and install S2_X522-NA-OP-IFXNAOP5802102141S-5.8.021S.zip
9. Reboot
How and Why did this worked I don't know, I am a noob but please try if you find yourself in the same situation as I was, you don't lose anything with trying, if this doesn't work don't blame me, this worked for my phone.
Greetings friends!
Thanks for putting this guide together, I am in a similar situation in that I reverted to stock everything (1. Installed YDSS chinese twrp, 2. Installed S2_X522-NA-OP-IFXNAOP5802012141S-5.8.020S.zip. This flash was supposed to have installed the stock recovery and overriden the ydss twrp, but didn't, I had to manually flash that after. Everything came back smooth but my updates also failed at recovery.
I am wondering where you got the LeEco_X522_5.8.019S_OTA.zip, bootloader-20S-s2.zip & twrp_s3.img from?
Nice to hear you finally got it to work ! Aren't the X520 and the X522 the same phone ? Why official ROMs are not compatible ?
