SamHD V2.1 Custom ROM and boot.img issue

Hi guys,
I wish to install SamHD V2.1 which is recently been released by Kumar Abhishek, but this time he has not integrated the boot.img in the zip itself but just posted the ramdisk to make updated boot.img from boot.img of stock ROM.
I am not too comfortable in using SP Flash Tool as its driver always give me trouble, now my question is:
I have made my own updated boot.img using Android Kitchen now can I just integrate the boot.img in the SamHDv2.zip and flash my device like we use to do it with the older version of the Custom ROMs, is it safe to flash like this?
Secondly, would I be able to boot my device properly after flashing SamHDv2.zip and Gapps.zip (without flashing boot.img with SP Flash Tool)?
I am asking so if it boot properly can I use MobileUncle to flash updated boot.img?
I think if I integrate updated boot.img in the SamHDv2.zip it should work fine after we used to flash in this fashion earlier also but I got to be damn sure before I go ahead.
Please guys guide me I am a newbie.

Update to 4.2.2 from 4.1.2

Hi folks! It has been a while since I have been on this forum; and I have a question about how to update from 4.1.2. to 4.2.2.
The process is not quite clear to me. Can I just download the Asus Firmware and flash through existing TWRP recovery (4.1.2 version)? Do I have to flash a kernel and new recovery using fastboot first? I see some step-by-step guides but also a view warnings. It is a littlebit vague to me what to do.Can anyone guide me through the process please?
I am on Hydro 7 but looking to update preferably to another custom 4.2.2. base rom. Tips are welcome
Best way is to download the firmware from asus website extract it (theres a zip inside the zip) and flash it with twrp, this will get rid of twrp so after the first boot find the approprate version of twrp and reflash it with fastboot, from there you can flash custom roms/ kernels at will
goodluck
I'm not sure if twrp will work. My upgrade path was to use fastboot the official zip from the Asus website, then fastboot twrp. Be careful which version of twrp you fastboot because it will cause a brick. I think twrp-2.5-4.2 should work for the US version for the official blob from the Asus website. For the WW version of the blob I used twrp version 2.4-4.2 successfully. Good luck!

Hi
I'm also still running 4.1.1 on my TF300TG (WW-version).
The bootloader is unlocked with the asus-tool, cwm-recovery (CWM-based recovery v6.0.1.3) flashed with fastboot and the system is rooted with supersu.
Now i want to update to 4.2.1 but it won't work. neither with the SOP for manual update nor from cwm-recovery.
From what i found it should work like this:
- download the 4.2.1 (10.6.2.6) rom file from the asus website
- extract the zip (once)
- open the second zip and open \META-INF\com\google\android\updater-script
- delete everything except "assert(package_extract_file("blob", "/tmp/blob"), write_raw_image("/tmp/blob", "staging"),delete("/tmp/blob"));
set_progress(1.000000);"
- save file and save the zip
- put zip on sdcard and install from cwm-recovery
can someone tell me, if this is correct? or if i should only flash the blob with fastboot?
any help is appreciated!
thx!

Need Stock rom for Prestigio 5870C urgently

Hello all!
Please, if someone can provide the stock rom for this device, the one that I can flash using stock recovery, I would really highly appreciate...
My device is bricked, and fastboot is not working. I have tried all the drivers out there, but simply, once in bootloader mode, device is not accessible...ADB is wokring however....
Stock ROM is my only hope...
Thanks!!
Update:
I managed to flash CWM using RKandroidtool, but I can not jump into recovery.It is pretty much stuck so if somebody could at least export kernel.img and system.img I would really appreciate ..or provide fool upgrade firmware img

[Completed] Need Help! Bootloop in 6044d. Need stock boot.img or recovery.img or stock ROM

Hi,
I was messing around with the phone and got a boot loop. I can't find the stock rom online and Alcatel doesn't have the official upgrade tool for my phone or at least I couldn't find it. I was going to compile android from source for this phone cause no one else has done it before but I need the stock boot.img or recovery.img for configuring build options in compilation environment in order to compile custom CWM and CM 13 or 14 o any other custom ROM.
Can anyone post me those stock boot.img or recovery.img so I can compile android from source for this model. I promise as soom as I get it going I will post results.
Thanks in advance!!
Regards!
Hi !
I see that you have posted here as well https://forum.xda-developers.com/an...d-bootloop-t3493789/post70812290#post70812290
Let`s keep it in one place
I would suggest you to search on the manufacturer`s website as well for a stock rom and be aware of the issues which may arise while rooting
Good luck !
