[Completed] [Q] Teclast X80h Bootloop after editing build.prop - XDA Assist

Hello,
I have a Chinese tablet "Teclast X80h (FB5M) Dual OS" Windows 8.1 FULLY ACTIVATED & Android 4.4.
On Android the play store not working so by following the instructions of many forums I rooted and modified three strings of build.prop:
ro.product.device=picassowifi
ro product. locale. language=en
ro product. locale=US
On restart goes bootloop. I tried the hard reset from recovery but doesn't solve.
I haven't backup and haven't installed the CWM recovery on the device so I can't flash custom ROM with ADB sideload. I found the custom ROM online but doesn't contain scatter files so I can't flash it with SP flash tools.
Could you please help me to solve this problem?
Gabriel.

[DEV] unofficial ClockworkMod Recovery 5 for Ingenic JZ4770/JZ4760 tablets

this is a work-in-progress development project for porting ClockworkMod Recovery 5 to Ingenic JZ4770/JZ4760 tablets.
this is not perfect at all. and I'm very busy. progress will be very very slow. I may not be able to answer your question/request. if you have some idea for improvement, please do it freely.
there is no support from any makers/vendors. you must agree all risks by installing non-supported files, it may brick your tablet, and you may lose official support/warranty.
* YOU MUST READ CAREFULLY POST#1, #2, AND #3!
* DO NOT USE IF YOUR TABLET IS NOT LISTED BELOW. IT WILL BRICK YOUR TABLET!
* project page
http://androtab.info/mips/ingenic/clockworkmod/
* supported tablets
ainol NOVO7 Basic and Paladin
Velocity Micro Cruz T100 series (Android 2.2 updated model and Android 2.0 PT701i model)
Velocity Micro Cruz T301

https://github.com/naobsd/mips_external-busybox/compare/ics...ics-mips
* How to install ClockworkMod Recovery 5 (for ainol NOVO7 Basic/Paladin, Cruz T100 series, Cruz T301)
1. download recovery-signed.zip for your tablet (DO NOT USE FILES FOR OTHER TABLETS!)
2. (if you are using stock recovery)rename it to update.zip, then put it on root of SD card
3. install update.zip from recovery
on stock recovery, update.zip will be installed automatically. on ClockworkMod Recovery, you need to select menu item manually.
* How to install ClockworkMod Recovery 5 (for ronzi A3)
1. download recovery.zip for your tablet (DO NOT USE FILES FOR OTHER TABLETS!), then extract recovery.cpio.img from it
2. make backup of stock recovery
Code:
adb remount
adb shell mv /system/recovery.cpio.img /system/recovery.cpio.img.bak
3. copy recovery.cpio.img into your tablet, then flash it
Code:
adb shell inand_flash_image recovery recovery.cpio.img
* How to boot recovery
push & hold VOL+ while power on
* How to boot recovery (alternative)
Code:
adb reboot recovery
*How to control ClockworkMod Recovery 5
VOL-/HOME: down, VOL+: up, POWER/MENU: select, BACK: back
* Superuser, su, and busybox
it can be installed from ClockworkMod Recovery 5
- Superuser, su, and busybox for JZ4770 ICS
- Superuser, su, and busybox for JZ4760 Froyo
* random notes
- stock recovery
if you installed update.zip from stock recovery, stock recovery image should be renamed as /system/recovery.cpio.img.bak. (unless you didn't remove /system/recovery.cpio.img)
it can be flashed by "inand_flash_image" command. (use "flash_image" command for T100 series except PT701i model)
- mbr, xboot, boot, and recovery areas
backup/restore doesn't work for mbr, xboot, boot, and recovery areas
- time for reboot/poweroff (NOVO7 Basic)
I don't know why but reboot/poweroff take long time (as same as stock rom). you should wait 1 minute. if nothing is happened in 10 minutes, use reset hole
for now I'm preparing to push my changes to github. I'm very busy so it needs some time.
if you made some.zip file to do something for MIPS Android (e.g. superuser.apk with su binary for MIPS), please tell me. I'll add link to post#1.
if you have some idea for next work, please tell me too. (but, as I wrote, I may not be able to answer your request. sorry)
Thanks for your starting thread and project.
I bought a Advanced model but they send us a Basic Novo7.
All we know the incompatibilites using a cpu MIPS, that doesnt allow to run a lot of Android software that for default its compiled for ARM processors.
Im getting a bundle pack of apps running under our device.

thank you. I understand your condition.
but here is dev thread for clockworkmod for novo7 basic. if you want to talk about apps which support mips android and/or any general things about novo7b, I recommend you to make new thread for it.

I will do as you said
This is great news. If you are wanting to test any work with users on Velocity Cruz t301's which also run an ingenic processor (JZ4760) .
UPDATE: Tried running CWM for the hell of it on the t301 . Stuck at boot screen was able to get back to original recovery however. I'm guessing it might be due to the entry point into the kernel . Since the t301 is ancient Froyo. Would love to take a look at the source
Also here SHOULD be a working SU for MIPs. It work's on the cruz tablets

I couldn't read what you did exactly. if you flashed my image w/o modification, it must not work. as I wrote, DO NOT USE file for other tablet.
please explain what you did, and please explain detail about your tablet before any random work.

Attempted using the above stated method(understanding you said DO NOT US file on other tablet) I was curious to see as what kind of error would or may of come up. I'm interested in modifying this for the Velocity Cruz T301 tablet(running a JZ4760 processor) as that community of tablet users has been left under the dust. Now with the novo coming out it will further pile under the dust. I have not yet made any modifications to it, although I would very much like to.

kernel must not work because it's for NOVO7B. in general, kernel can't be shared among different products.
key assign, and partition layout may be different too. but currently I have no idea how to fix them because I don't have any detail about your tablet...
http://en.ingenic.cn/product.aspx
it seems JZ4760 is NOT MIPS32R2. then I need to recompile userland binaries.
anyway, technical detail is required to support other tablets.
http://bbs.imp3.net/thread-10520163-1-2.html
it seems source code for xboot, android 2.2 and (part of?)kernel source for NOVO7B is released. I don't try to compile them yet so I may be wrong.
I'll check them later.
Is it possible that someday this recovery will be also ported for ainol novo7 Advanced ?

How did you get back to your stock recovery image on the T301? I think I borked mines on a T105 accidentally with ROM Manager. I accidentally pressed the screen too many times while 'exploring' and the delayed input caused ROM Manager to start flashing a recovery. Now I can't boot into recovery. I just see black nothing.
EDIT:
Disregard - My stock recovery boots. I was performing the boot into recovery procedure incorrectly. Also, because the recovery.cpio.img was in /system I assume it was flashed on each power cycle.
Apologize: I have read the complete topic and now understand that at present it is only for Novo.
Please dont use this thread to talk for another devices that arent be Novo7 Basic.
Asi cant start a new thread yet, here is my thread at spanish forum comunity with a full starter packs of mips app + games and a guide to be root.

Oppo F3 Root Help

Dear Xda,
Im An Oppo user my Device details As follows.
Device: Oppo F3 ( CPH1609)
MTK6750T
4Gb Ram, 64 GB ROM
Running on ColorOs 3.0.0i (Based on Android 6.0)
There are lot of problems / bugs in Os which Oppo Even failed to rectify.
When ever i Mailed them they simply quoting their common quotes
So i decided to Root my phone to develop ( no i cant do it lone )
During search of Root i found few obstacles
1) Oppo made decision to remove fastboot option fron their device
Ref: https://forum.xda-developers.com/r7-plus/help/decision-oppo-bootloader-fastboot-t3348114
2) MTK droid Tools not fully supporting the chipset
Ref:https://forum.xda-developers.com/attachment.php?attachmentid=4178413&thumb=1&d=1497202499
3) One click Root is not working ( king, farma etc)
4) cannot obtain boot & Recovery imgs to development
5) i thought stock firmware flash file may have useful but there are 2 types of probles
(A) flashablezip version : it has boot. Img but no recovery.img included. Also it is With. Ozip Not with. Zip extension
(B) PC version : it is like encrypted file. With. Ofp extension And With some other type file. And it is not flashing through SP-FLASH TOOLS. The flashing tool is different.
Ref https://m.youtube.com/watch?v=qw4HIQER0mg
Guys thease are my problems. Coz of those i failed to root my device.
My only Hope is Xda, you people know better than me ( probably Best) . Please analyze and and give suggestions.
Thanks In Advance

Hmm well, have u tried peeking at the device manager when you phone is connected to your PC in fastboot mode?
If there's an entry showing your device you will need grab a fastboot binary to flash the firmware.
Here's a link to the tool called minimal ADB and Fastboot: here
You will also need to extract the firmware to somewhere in your drive.
Having done all the extraction and installation,
and since you're on Windows, you should do:
Bash:
\path\to\fastboot flash:raw boot \path\to\boot.img
\path\to\fastboot flash system \path\to\system.img
where \path\to\fastboot points to the path where you have extracted/installed the tool (or if you have added its path to the PATH environment variable, you can avoid the hassle to write the full path), and \path\to\boot.img and system.img points to absolute path of the extracted firmware.
Then, you are good to go!

I regret to tell you that, no. Currently I have been using the phone as a debian server, since the LCD has been inadvertently broken ( I exerted too much force on it ). Moreover, the device doesn't recognize its battery, which suggests that I might have broken some part of it. Therefore, I have kinda lost any hopes for it. Plus, my linux machine is not powerful enough to build an android OS ( what do you expect much from an intel celeron? ).
PS: I might do it once I get my hands on a much powerful one, or maybe a powerful enough VPS? I am not quite sure but currently I am still in high school, meaning that I may or may not have time....
Best regards,
B83C
