GSI builds on Lenovo M7 (TB 7305f) - Upgrading, Modifying and Unlocking

Hello fellow M7 tab users,
I had recently come across various GSI that can be flashed and run directly. these may or may not work.
Link: https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list
flashing method: https://www.xda-developers.com/flas...48.128019215.1650719838-1694315489.1650719838
M7 does support treble and has a only configuration. although it is not in the list of supported devices.
you take the help of this video too:
currently there is twrp available for M7

and rooting is also possible using Magisk {Mod edit: Link removed. Oswald Boelcke, Senior Moderator}
magisk link: {Mod edit: Link removed. Oswald Boelcke, Senior Moderator}
...
Could some experienced people look into it, the source tree for the M7 kernel is also available in lenovo site: https://support.lenovo.com/in/en/solutions/ht511330-lenovo-open-source-portal. I have no experience in porting or making custom ROMs, the GSI method made sense so I tried flashing few of the GSIs of android Pie but it was of no good, boot loops and phone stuck at logo. Could many of us come together and check each and every one of GSI through trial and error to confirm that M7 doesnt support this method.

if a GSI build gets stuck in bootloop or stuck at logo then the power + vol down keys make the phone exit the situation momentaryly, it might start looping/ getting stuck at the logo again so that time you can take it to fast boot by going to recovery by pressing all three buttons together then booting to the bootloader.
when it is at the fastboot you can recover your phone again by using lenovo rescue and smart assistant(RSA) . when the RSA software tells you to press vol + and attach usb jack at same time , you can exit the fastboot by pressing the power button. for some time and when screen goes off quickly follow the press the vol down key and plug in the usb cable and wait till the software makes the device stock again.
The twrp will be lost when RSA is used so again the steps in the first post need to be performed. twrp backups do not recover the phone due to some reason so I think this is the only way to recover stock android and then try the next GSI.

It's not deleted, it's just in a non-public forum, pending the outcome of a discussion between the Author and our admins.
I did not deal with the incident, so this is the only info I can find.

12. Using the work of others.
If you are developing something that is based on the work of another Member, you MUST first seek their permission, and you must give credit to the member whose work you used. If a dispute occurs about who developed / created a piece of work, first try to settle the matter by private message and NOT in open forum.

Please keep all non Development relevant chatter out of development threads, It is recommended to make a separate thread in the Q&A section for non Development related comments and questions, valid replies within a development thread are: BUG Reports, Problem, Troubleshooting Steps & Logs.
... and Please! keep all your personal bickering via PMs, do not pollute the forum with your personal indifferences.

Rom OP Format and Thread Title...DEVS READ PLEASE
ROM OP
Click to expand...
Click to collapse
Below is a format that should be used as an example of how a rom thread should look. It doesnt have to be exact. I suggest that you stay creative and use all the features in the advanced panel when creating a thread.
1. Name of rom, team, etc
2. Introduction
3. Changelog in code or php tags
4. What's included in the rom in the (apps, tweaks, scripts, addons, mods) in code of php tags
5. What works/what doesn't work in code or php tags
6. Credits (Users name-with link to (profile/github/or thread u got tweak from embedded), and what they did to help you)
7. Screenshots (2-10 different screenshots of different aspects of rom)
8. Kernel with either link to thread you got it from or github (if stock sense or cm please state that and that is enough)
9. Instructions on how to install the rom (also if special instruction for a2sd or beats audio...etc)
10. Do's and Don'ts of the rom
11. Questions & Answers section (I find this helpful to write out asked questions with solutions at the bottom of the op. I find that it cuts down on the question being asked a million times)
12. Finally the dl link
13. Additional add-ons (this can go into first post or reserved posts after)
Click to expand...
Click to collapse
I find the embedded link looks and feels better throughout the op if possible.
All sections should have a header with enlarged text and spaced out so people can read it easily.
I am hoping that this helps to make this section a little cleaner and easier. enjoy
The way I look at this is that it takes US weeks/days/hours to make these roms....we can take the time out to make sure that the op looks professional and clean
Also Make sure the op is fully ready before posting. I know we all get excited to release a rom but stating that half the stuff will be updated as time permits just shows that you are lazy and in a hurry which doesnt look good cause if thats the case then how does your rom run....
No posting a a rom thread without a DL link either
Thank you to Papa Smurf151 for the basis of this post.

I've removed all links to Telegram from this thread. As an exemption from the last bullet of rule no. 5 of the XDA Forum Rules, we grant only developers the privilege to share references to their social media in their own development threads. These conditions obviously don't apply to this thread or you. Please refrain from sharing of social media in future. Thanks for your cooperation!
Additionally, unless you already know Telegram is not accepted on XDA as a filehost because a download of a ROM would require a registration on Telegram.
