I am sorry if you don't like my answer as I know your device is not the same as this TWRP but you may like to port it? or compile it?
I think you need to root your device as well otherwise you may struggle.

Note this is tested on S7-931W while your post shows you are keen to get s7-932u.
If you use Linux you can download that TWRP, unpack it with imgRePackerRK
http://forum.xda-developers.com/showthread.php?t=2257331
then use Android to get info on where your recovery is and take a backup image of it
copy your stock recovery to Linux, unpack it with same tool as above, then swap in your kernel into TWRP and adjust the fstab and a few text files to match your ids
repack modified TWRP with imgRePackerRK and flash it.
making sure you have kept a backup on your removable sdcard.
good luck
This friday I got my tablet(lenovo tab 2 a7-10f). Yesterday I decided to install better rom on it. I rooted my device and installed twrp recovery. Unfortunally I didn't quite realize the importance of making back up and the fact that you can't flash this:
https://forum.xda-developers.com/android/software/rom-orionlp-v1-8-lenovo-tab-2-a7-10f-t3480918
on android 4.4. My device loops "lenovo powered by android" screen. I can boot it into TWRP recovery. I have been googling today for a whole day and I havent find any rom to flash it. I tried this:
https://forum.xda-developers.com/an...-stock-lollipop-5-0-roms-lenovo-tab2-t3418835
and I think thing like this for a KiKat (through twrp, probably that's why it doesnt work) .I couldn't quite boot it into fastboot and I can't use sp flash propely or it just simply doesn't work for me. Please help me to find any rom to flash it from twrp, since I am too stupid to do anything different way.
In short it loops, I can boot it to twrp, I just want to unbrick it. The ultimate goal is to propely install this *first link*
Thanks in advance!

There is a way to flash a now rom with SP flash tool although you can't use sp flash tool propely.
You must open the lid of the tablet and unplugin the battery
(to unpluin the battery simply pull out this)
Then open your SP flash tool, load the scatter file of the rom, press download button, plugin the battery and your pc will start dowloading the rom normally.
Hi everyone. I recently bought an Alcatel 1t 7 (8067) tablet, 1Gb ram, 16Gb rom, just wifi (no 4G), mt6580 processor, android oreo go edition; a very simple and cheap tablet, but it seemed me a very nice one, because is slim and lightweight; worhty of root access, but also a custom recovery. I prefer TWRP recovery because it's more organized... ¡Anyway!... So I got down to work, but at first, as I didn't know how to backup all firmware, and when I learned how to do it and did it (esentially I could "tame" sp flash tools, hehe), I had already lost my original recovery file. Is needless to say that TWRP recovery, as far as I know, isn't available for this model, so I needed to port it, but as at first, I didn't know how to back it up, I overwritten it with other recoveries that didn't work. I mean, at this time, the tablet is working but is without recovery tool. I'm not going to talk about root access, because I already could get it, by using magisk manager, but I need my recovery image file, back; both to reinstall it and port it to TWRP.
So finally, if anyone has this stock recovery file, the full stock rom for it, or even better the ported TWRP for this tablet, please share it to me.
Thanks in advance for your attention.
just boot into android, stock recovery will be repaired from /system/recovery-from-boot.p automatically

Thank you for reply. Ok, I booted android. I have enabled usb debugging so, when android booted, I connected it to adb, and opened "adb reboot recovery" command, to be sure that android would reboot into that mode; but it didn't, it just rebooted several times on boot screen, and when it "got tired" of rebooting, it booted into android. Didn't boot into recovery, so I guess, It didn't repair it.
PS: I was looking for that file "recovery-from-boot.p" on that path, and there isn't such file, i can't find it.
on older devices it is /system/etc/install-recovery.sh or something, it's maybe disabled if your device isn't completely stock anymore?
you can port TWRP with kernel from boot. you can use this TWRP as base

¿Must that file have the same size that the original recovery image? Because the only file named recovery that i can find on that path is named "recovery-resource.dat" and its size is 807kb, and as I have seen before, is that recovery images have several Mb of size.

Two questions about it; as far as I can remember twrp image must be compatible not only for the same chipset, but the same screen resolution ¿Am I right? Also, this tablet is 600x1024 px, or 1024x 600 on landscape mode. All TWRP that I have installed on former machines, worked on portrait mode, so I wonder miself ¿Could TWRP also work on landscape mode?
/system/etc/recovery-resource.dat "generates a binary patch that creates the recovery image starting with the boot image. (Most of the space in these images is just the kernel, which is identical for the two," so the resulting patch is a executable file with smaller file size than the actual recovery.) It's just few lines of code.

TWRP is available in landscape mode. you can read more about here

I don't think touchscreen will work at all, so resolution doesn't matter. you can use TWRP from cmd line

Ok... I can find that file on my tablet, but I'm not so skilled android user, as for rebuild recovery from that file or even port TRWP from that file, so ¿Is there an easy way to do it ( or at least, comprehensible for middle skilled android users) ? ¿How? (and supposedly this machine is easy to port and root, they say on internet. I also have a huawei y7 2018 for rooting, that seems harder to root. But that's a another (my next) struggle in here, hehe)

Another question. ¿Are those programs who claim to help to port TWRP with just some clicks, reliable? (for instance TWRP porter for mediatek)

All the TWRP recoveries that i have ported before, have had a working touchscreen, but as I understand, resolution requirement is not only for touch calibration, but for correct displaying of TWRP GUI (that all buttons and options fit on the screen), Now I've read that new versions of TWRP adjust automatically to any screen resolution, ¿Is that right?
dump boot.img off device. you can use SP Flash Tool read back. download base TWRP and unpack with AIK. replace kernel and see what happens. if TWRP booted with black screen try to enter adb shell. get partition list from adb shell. create proper twrp.fstab and flash again. you should have functional TWRP now even without working GUI.
if touchscreen is disabled it might possible to hexpatch kernel with ghidra like I did for mine.
HCU-client needs 4 credits for Huawei.
I may reply in new thread.

¡No, man! If TWRP porting is kinda hard having the stock recovery image, without it, is a brain smashing task (or at least for me). I mean, I really don't understand well, how to port twrp starting only with boot.img, I mean, without recovery img. I've saw tutorials about the use of carliv kitchen (windows version), and seems easy, but all tutorials are made with stock recovery.img available, not with boot.img. So, what can I do there?
as I said. replace kernel with that from boot.img and see what happens? the generic base TWRP actually is recovery.img already, so you might lucky and it works? trial + error...

I saw a tutorial about. It said that I must to unpack stock recovery and twrp recovery, and replace some files of unpacked twrp recovery, with respective unpacked stock recovery files, and edit some files on twrp unpacked folder, and finally repack it.
Until that point, I assume that it should work, I mean, having stock recovery. But I did that, but using boot.img, I renamed all boot resources, to recovery, for instance, boot.imgkernel to recovery.imgkernel; and replaced it, repacked it, and reflashed it, but nothing happened, I mean, it didn`t want to boot into recovery. It`s interesting to "experiment", but I`m gonna try to find its original stock recovery, to at least get it back.
Hello!
I would like some help, alcatel 1T7" 8086 no4g I likely bricked it. There's nothing else than a black screen. The tablet doesn't react to anything. The computer finds it as unknown USB tool. No visibilty is shown. What can i do with it,for it to work? Or should i just put it in the trash?
Thank you for the reply.
