Hey guys,
I have a bit of a head scratcher. I am currently trying to flash my new Sanei n10 tablet with CM10 and it is proving much more difficult than I first imagined.
My main problem seems to be that the device just does not want to boot in CWM. I have installed the latest version of CWM (found here) via the Terminal Emulator but it doesn't boot into CWM Recovery, but rather just boots normally. I have also tried using the hard keys to boot into it but all that does is boot me into the default android system recovery (3e) which is useless as it will only update from verified roms.
The device is rooted and I have ROM Manager installed. I have given Terminal Emulator superuser permissions... It just doesn't seem to want to boot into CWM Recovery. I have tried using both ROM Manager as well as NOVO7 Tools to boot into it but I get the same results (device just reboots normally)
I think that it might be something to do with the stock ICS 4.0.4 that came with the device.that is causing me so much hastle, but I was hoping someone out there might have experienced a similar issue or can offer some insight to where I am going wrong.
Thanks in advance!

1. Download the latest ClockWorkMod for Allwinner A10 tablets from here:
http://forum.xda-developers.com/show....php?t=1802268
2. Put all three files in the ZIP inside the root of a MicroSD card and insert it in the tablet
3. Check from the Terminal app inside the tablet to see if the MicroSD card is mounted in /sdcard (just type "ls /sdcard").
4. If the "ls" command doesn't show anything (that's what happened in my case), then you must modify the "install-recovery.sh" file and replace all instances of "/sdcard" with "/mnt/extsd".
5. With the proper "install-recovery.sh" file, run the commands specified in the above xda link (in my case the card is in "/mnt/extsd" instead of "/mnt/sdcard" as the original example shows):
su
cd /mnt/extsd
sh install-recovery.sh
sh reboot-recovery.sh
6. The tablet will then reboot to CWM recovery. Then follow the regular steps to install Cyanogenmod (wipe plus install ROM + GApps + Compatibility). This time the Recovery menu won't care about the files being unsigned and will install them right away!
I have an MDK S4. I have been running beanstown's rom for months with TWRP 2.5.0.2 with no issues. Today I decided to flash clockworkmod touch recovery in terminal emulator using the following command:
su
dd if=/sdcard/ recovery-clockwork-touch-6.0.4.4-jfltevzw.img of=/dev/block/mmcblk0p21
So now my phone won't boot at all. All I get is a screen that says:
Secure fail: kernel
System software not authorized by Verizon Wireless has been found on your phone...
UGH!!!! So now what? Do I need to do the following or is there another way around it?

Thank you. My s4 is rooted. I *think* that I have solved my issue. I was able to get it to go into Odin mode power+vol down. I didn't connect to a computer (am at work and all of my android tools are at home). I just cancelled out of Odin mode and it booted up just fine. Now I tried to go into recovery again and got the same error as above and was able to get out of it the same way. I was able to go into ROM manager and flash regular non-touch CWM recovery and was able to boot to it without issue.
I suspect that my flash of the touch via terminal emulator didn't work right. Can anyone who has done it this way let me know how long the flash should take? I was at the su prompt and entered the dd line above (copy and pasted to avoid typos). It appeared to do something...there were some numbers maybe 5 or 6 per line and then it went back to the prompt so thought it was done. This didn't take it more than about 15 seconds to do. What should I see here?
I know that I can just flash it via ROM manager but wanted to be able to do it myself without rom manager and also be able to flash the latest twrp img if I want to (goo.im seems broken at the moment). Maybe I will try to do it via Odin later.
TIA.
you rock
I just got this same error and your steps worked perfect

Hello, I went to flash a recovery package with flashify and got the black screen with kernel fail. I was on the latest nk1 kernel.
please help
Hi! I'm really sorry to revive such an ancient thread but I've a similar problem.
I tried to use the dd command to update TWRP and wound up at this spot, but I was running a custom 5.1.1 system (jflte dev something or other from oct 2014 - recovery needed to be updated in order to install 7.1.1). So I tried to ODIN back to the old bootloader because I read it may have just become locked again, and now the system seems broken or missing, I'm not sure which. Phone no longer boots into the system and I get this error at recovery, so I'm hoping that if I flash an older factory image onto the phone, it'll restore it.
My question is, if I flash a stock image onto the phone, will it overwrite the bootloader and make my custom recovery dreams impossible? I went as far as to transplant the insides of this phone into a replacement when it first broke to maintain my MDK bootloader, so I'm really hoping I didn't **** myself here.
----
Edit:
So I've fixed my phone! The whole ordeal wasn't too too bad, but it was somewhat time consuming and difficult to divine on my own.
Now, I realize now I may have actually flashed the wrong .img file, which may have caused this whole issue. I'm actually not certain, because through the method that I fixed this problem with, I was able to flash what I would later find out was an incorrect .img for the recovery (jfltexx instead of jfltevzw ) but it did work properly, and I only found out when I got an error on trying to install the LineageOS zip.
I tried a bunch of things, but the one that worked was converting a twrp .img file to a .lok (loki) file. At the time of this writing, it happens that there's a bug in the latest twrp version that also prevents you from installing the system, but downgrading back to an older version will work, and I assume after 3.1.2 the bug will be fixed.
In order to do this, I wiped the system back to an MDK 4.2.2 system image I found here: https://forum.xda-developers.com/showthread.php?t=2301259
(dead link? Here's an archive: https://archive.is/LDnaY - I hit a bunch of dead links when I was figuring this process out and it was frustrating)
which preserved the mdk bootloader (because flashing anything newer than this will lock the bootloader, I've been told. I didn't dare try.)
I rooted that image by downgrading to the prerelease kernel and using motochopper to root, then upgraded back to the mdk kernel.
Then I grabbed the loki_tool from this thread:
https://forum.xda-developers.com/lg-g2/general/guide-how-to-flash-cwm-6-0-4-4-lokitool-t2813514
(Dead link? Here's an archive: https://archive.is/F7k29 )
and used a twrp .img file to create the recovery.lok file
Flashing through this method restored my custom recovery, and also made the samsung unlocked padlock bootscreen go away (I miss it already!). Having Android 7.1.2 on this phone is quite a treat though!
Hope that anyone else who winds up here in the future finds this useful! And I hope those links
So, I've stupidly let my son try and flash a custom rom on his generic chinese tablet (Cambridge Sciences StarPAD 9 SE) and he found a few very similar spec tablet roms on the internet which said they require TWRP to be installed before flashing. So he's installed that, rebooted into recovery but the TWRP doesn't fit the screen in terms of resolution size. Now, that's not the main problem. The main problem is that the touch screen doesn't work at all within TWRP so I can't select any of the options. Whenever I power off the device and power it back up, it reboots to TWRP and doesn't boot to the main ROM. He said that it did originally reboot to the ROM whenever he first installed the TWRP because he said that it was the only way of getting to the recovery. So I thought that I could just use ADB and just force a reboot from there but off course, there is no ADB device driver to be found on the internet.. well not that I can find anyway.
I'll attach a photo for you guys and hopefully someone can help me with this as I've spent the best part of 2 days trying to figure out a fix but am now stuck.
I'm now able to access the device by adb however I don't know what to do from there.
Any help?
Does anyone have any firmware for this device? I can't find anything on the internet at all. If I could get a firmware img then the device will be fixed.
The build number from the firmware is: fiber_evb-eng 4.1.1 master 20130530
the command is "adb reboot" AFAIK
Did he take a nandroid backup before flashing? It looks like a version of twrp that is not compatible with the tablet was installed. Not every device supports touch screen recovery mode. Can you use the volume rocker to navigate?
I can almost guarantee you won't find the firmware for a Chinese tablet. I've just been trying to help someone in a similar situation but the best we could manage was a ROM that had lots of glitches.
Edit how did he flash TWRP if it was incorrectly flashed ie: fastboot flash boot recovery.img instead of fastboot flash recovery recovery.img then that may produce a device that would boot straight into TWRP. I've heard of that happening on a nexus 7

A while back, Amazon automatically pushed an update to my kid's Fire HD 6. Since then, the device will boot up and then it just freezes. The screen stays on the device is unresponsive. I am able to get in to recovery on the device, and that all seems to work fine, but booting in to Android is useless because it just locks and you cannot do anything with it.
I have been trying to go through this forum to see what my options are for sideloading another firmware or TWRP or anything like that.. and the posts here are not entirely helpful (for me at least). I'm used to going in to recovery and flashing some zip files to install TWRP, Cyanogenmod or GAPPS or anything like that... but the instructions I see for installing TWRP and the like do not seem to be the traditional methods. From what I think I am seeing, to install TWRP you need shell access to the tablet and then you can use dd to write TWRP to the correct storage space.
What are my options for doing things through recovery with adb? Or can I load an old firmware and then go from there? Any help is appreciated - would really love to get CM12 on this thing in the end if I could.

Your understanding of TWRP is right. Basically, we dd the twrp image with OS 4.5.3 bootloaders (the only bootloaders that will boot unsigned recovery) and then before leaving TWRP flash back (almost) current bootloaders and recovery.
You should be able to adb-sideload the OS 5.1.2 update to fix the freeze. Was device rooted before it updated? Do you know what OS it was on? If you have adb access while device is frozen, run these commands for current OS info:
adb shell getprop ro.build.version.fireos
adb shell getprop ro.build.version.number
No CM12 available. Mostly-working CM11 is here: http://forum.xda-developers.com/fire-hd/orig-development/rom-cm-11-kindle-hd6-t3270138
BTW, I assume you tried wiping cache and/or factory reset in recovery. If not, I'd do that first.
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.

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.
