Hi. I had endless issues last night trying to install a nightly build of Cyanogenmod 10.2 on my Asus tf300t. Long story short, after the CM update from within android, the recovery mod (CWM) had trouble mounting the sd card. I then flashed the latest version of TWRP and tried to update the bootloader by installing the latest firmware from asus, at this point everything went well. Back to the updated bootloader, I tried to install the nightly CM and still got mounting problems so again, I tried switching between TWRP and CWM. Now, I'm suck. I cannot get passed the asus boot logo: after a few seconds, it falls back to the recovery mod (I may have wiped the newly installed system). At any point, holding power+vol-down has no effect, I cannot get into the bootloader menu and enable fastboot. Only thing I have left is access to CWM and access the device via ADB. Can anyone recommend me a course of action?
Also, I'm trying to get one thing straight: what is actually needed to install a recent version CM? There seems to be some intricate dependencies between the bootloader version you're using along with the version of the recovery mod and the CM / android you're about to install. (If anyone can clarify this for me, it would be really appreciated).
Any suggestion regarding any ways on how I could recover my device will be greatly appreciated!
Thanks!

"Bricked" seems to be oftenly abused around here. Having ADB access and being able to boot into CWM, isn't there anything I can do to enable fastboot, force a bootloader downgrade or something?
Thanks!
This is the only thing I can do for you

Moral of this story: "bricked" really is an abused word around here. For anyone in my situation, namely: stuck in a boot loop where power+volume down has no effect and thus is preventing access to fastboot, if you still have adb access, you can issue: adb reboot bootloader, it should at least allow you to access the bootloader again and from there, fastboot. The above linked post really was helpful. Thanks!

"ricked" may be abused, but I don't understand your situation very well, much less how you extricated yourself from it. If you're in a boot loop, you cannot complete the booting process (much like a tab with bootloader, recovery, but no OS installed). Without it, you have no access to ADB. Which in turn doesn't allow you to issue ADB commands. If additionally, you have no access to fastboot because volume down+power, and/or reset+volume down, does nothing (bootloader with icons absent), you cannot issue fastboot commands. Without the two, and the uselessness of APX mode, I'm not sure why that's not characteristic of a soft brick.
I have a mainboard that shows nothing but the initial Asus logo (not the one with boot animation, i.e., spinning dots) and "the device is unlocked." If I use either fastboot or ADB from PC, it returns with "waiting for device..." You were in the same boat, were you not? Looks like part of the firmware is still there (I assume if you replace the nand with a brand new, blank one, nothing would show up on display) , but the bootloader is messed up. If you'd succeeded in resurrecting your tab, then how do I rectify it, if you care to enlighten? Thank you in advance.
A couple of months back, I had unlocked the bootloader (I had stock 4.2.1) and rooted this tablet in order to put Cyanogenmod on it. The current version was CM10.2 (nightlies). I was able to update to different nightly versions and then to the stable 10.2 version. Recently, I saw CM11 nightly versions beginning to appear, so I thought I'd install it.
Using TWRP 2.6.1.0, I had been able to do all of my CM10.2 updating. However, with CM11, the initial flash didn't work (I did clear cache and Dalvik), and so I thought I had to update TWRP. I downloaded TWRP 2.6.3.0 for the TF300T (both .img and .blob) and tried to fastboot them to my device. .img did not work, but then the blob fastboot was able to install TWRP, however, there was a password lock. Reading about this online, I thought I just had to reflash TWRP 2.6.3.0. I tried that and got the same password issue.
Then, I thought that CWM would be a better option (although I thought I may have seen things about it not playing well with the 4.2.1 bootloader...). I flashed a version of that (not exactly sure what version... (which may be the source of my problem) but it was for the TF300T...). Then, upon rebooting, it got stuck on the ASUS loading screen (with "The Device is UnLocked." in the corner). So then I tried rebooting into the recovery, but then I couldn't access the recovery menu from power + vol. down buttons anymore.
Basically, what I can do now is restart the tablet (via holding the power button or pressing the reset slot), but it always gets stuck on the ASUS screen, or I can enter APX mode, but don't think that'll do much good since I don't have nvFlash installed...
Is my tablet bricked?
Thanks in advance!
PS - I saw some solutions that required opening up the tablet. I would be okay with doing that, but only as a last resort!

Try using fastboot to install this version of TWRP: http://forum.xda-developers.com/showpost.php?p=48512729&postcount=16
It will only work if you were on 10.6.1.15 or above. It allows flashing CM11.

The thing is, I can't get into fastboot the typical way; pressing power and volume down does not go into the fastboot mode like it did before. I can get into APX mode, though. Can I use that to flash a recovery? I haven't been able to find a way of doing that yet…

No, you need nvflash backups to use APX mode. Since you can't get to the recovery menu, I can't think of any other solutions....?
Same here
I'm in the same state after trying to update from 10.2 to 11. Just sits at the ASUS logo screen. No fastboot or recovery. I can get it to turn off by holding the up volume and inserting a paper clip into the reset switch hole. Otherwise I have been totally unsuccessful in getting it to do anything else. At this point I'm not adverse to opening it up. Do you have the link to the solution you found that required opening the tablet? Maybe I'll give it a try.

Well, I was trying to install CM11 and did something wrong... most likely I was flashing with TWRP instead of clockworkmod recovery.
Moreover, shame on me, I did a "wipe data" or similar thing while in the confusion and now I have just the message "the device is unlocked" when booting - no access to TWRP when holding power+volume down, nothing else... am I in a dead-end? any suggestion?
Thanks in advance!

So since I feel like I have a complex problem that I can't seem to search for, I'm piggy backing this thread. It's been a year since I rooted this tablet, and I went on deployment with it. Worst ROM ever, couldn't get YouTube, WiFi was sketchy at best so I came back and it even had the OTA updater to update to a newer version, well that wouldn't load at all.
So I was in the process of trying to kill this crap ROM and upload I think CYA.. eh it's not the issue. So the first thing it asked me to do was this TWRP (which is new to me from a year ago) and I installed v2.5.0.0. When the tablet was working, that program seemed to work just fine, but when I rebooted in to RCK, it's so skewed and off center that I can't see half the screen. So when I tried to update to this new ROM, I kept getting download faults, so I figured I was stuck with this crap ROM because basically I quit trying. Well I tried to restart my tablet and this TWRP thing came up and asked if I wanted to run this (NEWVERSION).zip (I don't want to call out the development team, I'm sure their most recent update is much better) but basically it was the new version of the ROM I was running, so I let TWRP (from the loaded up tablet) to "install new zip" so I of course wiped data, cache and dalvik (I didn't save anything to this tablet, nothing to lose)
Well now, I'm stuck in the bricked mode of ASUS screen. If I hold down volume and power, I get RCK/Android/Wipe Data. I ever get the computer asking me to install new drivers, but of course it won't recognize the TF700 as a disk.
Any suggestions on how to get this thing back?
First the good news:
The page with the three icons is the bootloader menu which means you should have fastboot access to your tablet from your computer.
You can use fastboot to flash a new recovery (TWRP) and once that is installed you can flash the new rom.
So this can be fixed relatively easy, but you have to do some reading before attempting it. Done correctly this is a safe procedure. Done without understanding what you are doing could leave you with a hard brick - right now you're probably just soft bricked.

I am not sure what happened here. I have used TWRP since version 2.3.x and never had the problem you describe. I suspect you installed a version for a different device - not the one specific for the TF700.

Are you sure you had TWRP installed???
If I understand this correctly, you booted the tablet normally and got a notification to upgrade the STOCK rom to a newer STOCK version? TWRP would not do that - it just doesn't have the functionality to recognize a newer firmware version.
If you say you "let TWRP from the loaded up tablet to install new zip" - do you mean you were booted into Android? You were running the system? That would clinch it: Whatever you were using (and I am afraid it was ROMToolbox or some such) - it was not TWRP. TWRP is your custom recovery. You have to boot into it to use it.

Question: Did you unlock the tablet? Did you use the Asus Unlock Tool to unlock the bootloader or did you just root it? When you booted it up: Do you remember seeing "This device is unlocked" in tiny script in the upper left?
I assumed you were unlocked, but writing this post I developed doubt. I suspect you just rooted, downloaded ROMToolbox and tried to flash a new rom through it.
That does not work on this device. You have to unlock the bootloader, install a custom recovery and then you can flash a custom rom. Do not use ROMToolbox on this device!
So before I even attempt to explain the fastboot procedure, I have to know if you unlocked your TF700.
If not, you can't use fastboot.
Your last option then would be to pray that the stock recovery still works and flash the stock firmware.

TWRP didn't ask me about the update, the OTA Updater built into the ROM that I installed at the beginning of the year did. After I unsuccessfully tried to install the TWRP and CYNA ROM, I rebooted and the OTA came up saying a newer version was available, once it went to reboot into recovery, TWRP came up

Mmmhh, your tablet may need a little deeper cleaning. Check out buster99's post (#12). His method has helped dozens recover from worse than you have right now.
http://forum.xda-developers.com/showthread.php?t=2179759&page=2
His instructions are for the TF300. naturally you want to flash the blob for the TF700. That would get you back to a healthy stock system. Then you can again flash TWRP and through it a custom rom.
Good luck!

Are you saying the twrp flash went ok?
You don't flash the rom in fastboot. You boot back into recovery, choose "Install" and select the CROMi-X zip you downloaded.
But before you do that I would seriously suggest you format your data partition. That means you have to have the downlaoded rom zip on your external card (otherwise you will erase it with the format).
So boot into TWRP, choose Wipe > Advanced > Format data
Then go back to TWRP Home, choose Install and navigate to the CromiX zip. Make sure the box "verify zip signature" is checked and flash the rom.
Do this only if you have a working recovery!!! Do not attempt with your busted one!!
You can only access the tablet in MTP (as an external drive) if your system is working. It's not - yet.
OK, so here's the lastest for me. I tried to "adb push ROM.zip ROM.zip/sdcard/" - error: device not found. I also tried "adb sideload" -error: device not found.
Also now, instead of the computer asking me to install drivers for my new device, it's registered as a "android bootloader interface" I tried to download the ASUS android USB drivers and update them, but Windows thinks my drivers are up to date.

To use ADB you have to be in your recovery or the Android system needs to run.
If you have a working recovery back - why do you want to mess with ADB unless you are familiar with it? You are treading on thin ice doing stuff without really understanding what you are doing! What's the rush?
The problem is that I don't have a working recovery back. i still have that screwed up screen that only shows a portion of TWRP. It let me push that recovery to it, but I can't see enough of the recovery to actually flash something to it..
I tried to download the drivers and push those manually, but windows doesn't recognize it

Your drivers are working. You need different sets of drivers for different modes: fastboot drivers, adb drivers, mtp drivers.
Your tablet shows up as a bootloader interface because it is in fastboot mode - ergo the fastboot drivers are working.
You HAVE to get a working recovery onto the tablet. It will NOT work without a recovery. To push a rom zip to the tablet is useless - the only thing working on your tablet is fastboot mode.
If the recovery flash fails, try buster99's method. That should clean all the crud off your partitions.
But you need to have the Asus firmware blob file for this! You cannot do this with any rom zip!!
Edit: You did push the correct recovery this time, did you?
Hi all,
I thought it be good to warn all Alcatel Pixi 4 (4) owners. The current version of the stock rom of the 4034N, which is sold here in the NL has what I think is a terrible bug.
If you enable unlocking in the development options, go to the fastboot, all it takes is to unlock the flash and your phone will get stuck in the boot animation.
I tried to recover by formatting /data (/data is destroyed as could be expected to protect the userdata), but it does not solve the problem.
Flashing a custom ROM like CM13 solves this problem, but I bet this is the reason why I see so many calls on the Internet for Stock ROMs for the 4034N. Have not found a good stock ROM for it and also Alcatels Mobile Upgrade site does not seems to support the 4034N (probably still one software version for it, so no upgrade required yet?).
So better know what you are doing when messing with this phone.
Anybody got the same experience (I can confirm that this was tested by me and my friends with three different Pixi 4's)...
Best regards,
Peter
Good news!
I found out that there is a global site from Alcatel where you can find an update of Alcatels Mobile_Upgrade_S_4.5.9 which DOES support the 4043N.
The good news is not only that this software can bring your phone back to stock ROM, but also that if your Flash is unlocked before you recover, it is still unlocked after the recovery. So rooting is very simple then. Cost me 2 minutes to do it:
adb boot recovery.img (you can boot the twrp bootimage from ADB, no need to flash it) and then directly install the superuser.zip
Presto!
I think I'm seeing the same problem with a 4034X (UK variant, as sold by Tesco Mobile). Unfortunately, the mobile update software isn't working for me as it's detecting that I've already got the latest version of the ROM installed already and won't let me install it again. AIUI, the CM13 system has a few issues, so I'd rather not go that root, so would still like a stock ROM if at all possible. Anyone have any pointers?
Hmm. Have managed to get beyond the resetting user data boot loop with the following procedure:
* boot to recovery (power + vol up)
* from recovery menu, choose "boot to bootloader"
* at bootloader, connect via USB to PC
* run "fastboot -w"
* run "fastboot boot <filename for twrp recovery image>"
* at twrp recovery menu, run the standard "wipe" options
* reboot
Haven't yet finished booting, but it's gone to the standard boot animation, which I never succeeded in getting to before.
Update: 8 minutes and counting into the boot process. Doesn't look like it's going to work.
One question worth asking: does this mean that *all* operations that cause a factory reset on an affected 4034 cause a boot loop? Or is it only unlocking the boot loader?
I managed to soft brick my 4034X simply by allowing my email program to encrypt the device. The encryption apparently failed and now it's stuck on boot animation. As @jh3141 said, the Acatel upgrade tool doesn't work. I guess I need to find a stock ROM, but my Googling hasn't found one yet. Can anyone help?

Any luck with the UK version 4034X?
I'm stuck in the booting process just like you were.
me too - Pixi 4(4) chaos on unlocking.
Absolutely the same experience here.
I have nuked 2 of these trying to unlock. It is a brilliant phone, but this is a painful feature - as you describe.
My history is in one of the threads on this site. - I agree, I would love a stock ROM for it.

I also softbricked my 4034X after unlocking the bootloader and couldn't get the phone to boot into recovery or the bootloader. I eventually managed to flash a stock ROM with SP Flashtool as described here https://www.getdroidtips.com/install-official-stock-rom-on-alcatel-pixi-4-4/ - this restored the ability to boot into recovery or bootloader but the ROM wouldn't boot so I couldn't enable developer settings to allow OEM unlocking. I then tried flashing the ROM for the dual-SIM version of the 4034X (risky!) and this booted and I was able to unlock the bootloader and flash TWRP recovery. The next problem was when & flashed CM13 and got an error message saying that TWRP couldn't access /data. It then got stuck in a recovery bootloop. Next I used TWRP to format all the partitions but it still couldn't access /data and broke the ability of the Mobile Upgrade Tool to read the phone. My next step is to try flashing a different custom recovery but I'm rapidly losing the will to live and would be very interested in any suggestions.
UPDATE - got it sorted by re-flashing the dual-SIM 4034X ROM (even though I have the single SIM version!), flashing ctr-6.6-4034 recovery, doing a normal wipe then formatting the /data partition then flashed CM13. I guess the data partition must have got corrupted.
I have exactly the same problem with pixi 4 4043f. I unlocked bootloader and then flashed following your instructions on that link you shared. But I see is a white screen frozen no options shown just booting voice behind.... I have flashed it several times but same results I still cant entry fastboot or recovery... Volume down + power or volume up + power dn take me anywhere just that frozen white screen with booting ring tone in the back and thats it... Kindly guide me
i had a similar problem, but i always wanted to flash cm13, so i was fine.
There is an amazing thread here for our device.
For those of you with the 4034X, i have ported cm13 to it specifically, bu there are too many bugs, but if anyone wants it, just tell me!
also, can i just say, softbrick if you oem lock aswell :,(
i wanted to test something, but after fastboot oem lock, and then fastboot reboot, i get an android being repaired? key combo's not working, adb/fastboot not responding, can't remember how i fixed it when i oem unlocked ...
edit-
got into recovery with key combo, now it's just to fix it!
Can any of you guys with the 4034N try this method of rooting? Without unlocking the bootloader?

For reference: I tried this on a stock 4034X and it failed (couldn't persuade it to boot the custom recovery without going through the full unlock process). Fortunately, there are now copies of the stock ROM available for download (e.g. https://androidfrog.com/a3nr9) so with any luck I won't need to go back to the dodgy CM13 port that constantly runs out of memory and soft-reboots...
Update: I've installed the stock ROM I linked to above, and it seems to be working pretty well. Only issue was that the scatter file that came with it was apparently broken. Fortunately, one that I had hanging around from attempts to fix this problem last time seemed to work with it. I've attached that to this message in case anyone else needs it.

Thanks, I'll be sure to add a notice for 4034X users in the Magisk guide. I have yet to see a stable CM13 ROM for MT6580 with 3.18.19 kernel. There seems to be an issue with this device chip and ROMs.
Finally got root on the Pixi4-4034
Hi everyone,
yeah I finally managed to root the alcatel Pixi 4-4 (4034) (3G MODEL). It was really tricky and there are quite some issues you have to deal with.
Therefore please read carefully my instructions and remember I am not responsible for any inconvenience, do it at your own risk.
First of all you have to unlock the bootloader and here comes the first problem. On the Pixi4 this operation leads to a sotfbick because the unlocking process deletes completely the data-partition. The phone can't boot anymore and ends in a bootloop.
To resolve this problem you must reflash the phone with SP-Flash-Tool. After reflashing the bootloader remains unlocked so that you should be able to continue with the rooting process. The second problem is that I could find only one working ROM for flashing. It is for the 4034X, my phone was a 4034D (dual SIM), after flashing I had an 4034X what means that my Pixi became a single-SIM phone, I can live with that.
Here are the necessary steps to obtain root on the Pixi4
1. UNLOCKING BOOTLOADER
- Go to settings -> about phone -> hit many times on "build number" till developer message appears
- Enable "OEM unlocking" located in developer options.
- Switch also "USB debugging" on
- Open the command prompt window (cmd)
- Connect the phone to the PC
- Boot into fastboot-mode by typing "adb reboot bootloader"
- Confirm the debug authorization window on the phone, check "always allow from this computer" (afterwards phone should boot into fastboot, otherwise retype the command above)
- Unlock bootloader by typing "fastboot oem unlock"
WARNING: this deletes the data-partition leading in a softbrick and bootloop,
you have to reflash the phone afterwards to continue rooting!
- Confirm the unlocking with the volume-up key
2. REFLASHING THE PHONE
- I found only this working firmware for the 4034X on this page like described by jh3141:
https://forum.xda-developers.com/android/general/warning-current-pixi-4-4-4034n-t3463154/page2
- You have also to use the scatter file described by jh3141
- After loading the scatter-file in SP-Flash-Tool you have to link the missing img-files in the SP-Flash-Tool-Window
- If you flash the 4034X firmware over an 4034D you will end in a single-SIM phone instead of a dual-SIM.
- After flashing the phone will boot again so that you can continue with flashing the twrp-img.
3. ROOTING THE PHONE
- To root the phone you have to install the twrp-image, the one for the Pixi 4034 you find it here:
https://forum.xda-developers.com/showpost.php?p=68049551&postcount=97
- Download and untar the file at the bottom of the page: twrp-3.1.0-0-4034.tar
- Open the command prompt window (cmd)
- Connect the phone to the PC
- Boot into fastboot-mode by typing "adb reboot bootloader"
- Flash twrp by typing "fastboot flash recovery twrp-3.1.0-0-4034.img"
- Download Super-SU "SR1-SuperSU-v2.78-SR1-20160915123031.zip" from
https://download.chainfire.eu/1003/SuperSU/
and put the zip-file on the phone (external or internal storage)
- With the phone switched off boot into twrp by holding power and volume-up keys togehter
- In twrp go to "Advanced" -> "Terminal" -> Type the following code:
echo "SYSTEMLESS=true" > /data/.supersu
- Go back and choose "Install" -> flash the Super-Su-file (SR1-SuperSU-v2.78-SR1-20160915123031.zip)
- Reboot and you’re done, you have root and super-su on the PIXI4
- If you want to uninstall system-apps proceed to the next step.
4. UNINSTALLING BLOADWARE APPS
- You can’t uninstall system-apps directly from the Android-OS,
if you delete the apps with some uninstall-tools it’s strange but the phone will reinstall them after a reboot.
- To succeed you must uninstall the apps in twrp
- Be careful, uninstalling the wrong apps will end in a bootloop or bootfreeze and you will have to reflash the phone starting at step 2.
- Boot into twrp -> go to "Mount" -> check "System" -> go back and choose "Advanced" -> "File Manager"
- In file-manager navigate to the appropriate app-folders and delete the .apk-files
- IMPORTANT: before rebooting you have to wipe the dalvik-cache
- Go to "Wipe" -> "Advanced Wipe" -> CHECK ONLY "Dalvik / ART Cache"
- Confirm wipe and reboot
I personally like the Pixi4-4034, it’s a very small one that is very useful as second phone especially on holidays .
Have fun.

Hi all,
This is not the right forum, but I didn't see one specifically for Spark X models, so I'm sorry.
A friend of mine has a Wileyfox Spark X device, which was bootloader unlocked, had TWRP 3.0.2 installed and was running on the original firmware (6.0.1) but rooted and xposed installed.
Now an update came out for Android 7. To update the device, I put back the original firmware and recovery, started doing the upgrades and all went smooth.
Device is up and running on Android 7, however when I now try to install TWRP again, it won't work.
(fastboot flash the TWRP recovery (same version as before - 3.0.2) seems to work ok. I then go to pull the battery after flashing, put battery back, and start recovery by pressing vol down and power.
I see the device going to a black screen, then reboot and keeps doing this as long as I keep the vol down pressed. Once I release the device continues normal boot and goes into Android.
I assume this has to do with a change in Android 7?
Seems I can get TWRP working again, if I flash the original boot image, however then ofcourse the Android boot doesn't work anymore. (additionally once in TWRP, it seems /system cannot be mounted anymore and TWRP thinks no system is installed)
So in short, I believe I should get a newer TWRP version that is compatible with Android 7. I tried the different versions available on twrp.me (up to 3.1.1.0) however to no avail. None works with the latest android.
As such, the device is able to run in android 7, but without root. (no adb root option in developer options, adb root doesn't work either, kingroot etc also no go)
Does anyone have any options that I can still try? or could help me with a proper TWRP version that should work? (I did find some TWRP recoveries on 4pda (russian website) for Spark + that claim to be for Android 7, but those didn't work either))
Thanks !

Apologies for ressurecring a zombie thread but, OP has a spark X and you have a Spark, so it would appear that you SENIOR person in that model failed at the very first hurdle.
Am still wonderng if there is an sign of a 7.0 compatible twrp for spark X? Don't suppose anyone has a link to the latest Spark X firmware either?

I've tried TWRP 3.0.2-0 (i.e. latest from https://dl.twrp.me/porridgek3/): it flashes Ok but it won't boot up afterwards. I've tried 3.0.2-0 but as you say "it seems /system cannot be mounted anymore and TWRP thinks no system is installed)". After letting it finish, Root Checker (not unsurprisingly) says that device is not rooted. Have you progressed with this issue? BTW I've emailed TWRP Support (from their web page) asking if they have a working version.
Same problem here, It's pretty annoying. My sister's getting this same phone (on Android 6) soon so I might just make a full backup with TWRP on it and somehow restore it on my phone.
Systemless Root
I can't decide whether to try the rooting method given in https://android.stackexchange.com/questions/160130/how-do-i-install-systemless-supersu-in-samsung
The method is:
Sometimes the need for a systemless installation of SuperSU is not detected by the installation script, to force this to occur follow the following steps.
Start TWRP 3.0 or higher on the device
Go to Advanced - Terminal
In the terminal, enter echo SYSTEMLESS=true>>/data/.supersu
Press Enter
Exit to the TWRP main menu
Flash the current SuperSU as per normal
When flashing SuperSU, you should see in the TWRP recovery log screen mentions of system-less installation and patching of the boot image.
Has anyone had experience of this method?
Resurrection! This post shall LIIIIVE!
No, seriously tho, does anyone have any updates on the issue? Or could at least point me in the right direction to root a Wileyfox Spark X? At this point, any help is much appreciated, since I have not been able to get ANY method working for me.

I am afraid not, since I can't install TWRP. One info would help me out a lot tho: would an Android-Downgrade (from 7.0 to CM13) help with installing TWRP and rooting?
Steps taken earlier:
quite literally everything (that would make sense even remotely)
Steps taken today:
- Downloading TWRP 3.2.1-0 (https://twrp.me/wileyfox/wileyfoxsparkx.html)
- fastboot-unlocking the bootloader (no issues)
- trying to install TWRP (no issues there either)
- when trying to reboot straight to recovery, I don't get past the bootlogo, suggesting to me that either the install or TWRP was corrupted.
Any help one might get?
Thanks a lot?

The only version that I had success with was 3.0.2 from https://dl.twrp.me/porridgek3/"]https://dl.twrp.me/porridgek3/[/URL]
Even then, It's all hit & miss getting into TWRP:
1. If I do anything after flashing (e.g. booting as normal), I have to go into fastboot & flash TWRP again.
2. Once I have flashed TWRP (i.e. still in fastboot mode), I can't leave fastboot mode. Also, the phone will not switch off unless I remove the battery and put it back in after approx 10 seconds.
3. Even then it often refuses to load TWRP i.e. it goes into the Android Boot menu.
AlwaysLivid suggested that you can boot to TWRP by executing "fastboot boot recovery.img" (where recovery.img is the TWRP img file renamed) on MSDOS Prompt / Terminal according to whether you're using Windows or a Linux distro (e.g. Ubuntu which I use). Presumably this would be after you have taken the battery out for a few seconds before inserting it again and have then booted into the appropriate mode with the Volume Down & Power buttons held down.

Finally, your advice with "Fastboot boot twrp.img" worked magic!
Got twrp installed, but now I'm facing the same problem as you with the systemless root. I'll dig around a little and see what I can find.
