[Q] Help with P7500 root please - Galaxy Tab 10.1 General

Hello all,
After following some tutorials about rooting my P7500 tablet after flashing ICS ROM, I'm still having issues.
What I've done was:
- recovery mode -> wipe data, cache, etc
- flashed P7500XXLQ8_P7500OXALQ8_P7500XXLQ8_HOME.tar.md5
- flashed recovery.tar from droidbasement - the P7500 one
- some tutorials said to install ROM Manager and flash CWM Recovery - it didn't work - permission issues
- reboot into recovery mode (screen was flickering) - was able to install the root zip containing "su" and SuperUser. After still no root :crying:
At some point I flashed a bootloader which fixed the recovery mode flickering screen...after flashing ROM again, bootloader was overwritten I suppose as flickering screen was back
Am I doing something wrong? Am I missing something? I DID read a lot around here but all solution I've tried didn't work for me...F1 F1!!!

Yep, flashed via Odin (Windows 7)...About wipe, I've used both options from recovery mode menu: wipe data and wipe cache. Is there other thing that I need to wipe?
LE: I haven't used "advanced" option from that menu. Will give it a try once I'm at home. Thanks for the tip!
LE 2: OK, I'm @home and tried this:
- flashed the bootloader.tar.md5 which keeps the recovery mode out of flickering
- reboot in recovery mode, wipe data, wipe cache, advanced > wipe Dalvik cache then reboot again in download mode
- flashed stock ICS IT ROM
- reboot in recovery mode - no flickering
- flashed recovery.tar.md5 for P7500, downloaded from droidbasement => flickering in recovery mode ((((
Did I miss something here?

And of course ROM Manager says there are problems while attempting to run privileged commands even after installing the zip containing su and SuperUser. What else can I do to root my tablet? I've root'ed my I9000 so easy....

Unless you want to stay on the stock rom, or want to backup some apps, then no. Rooting will not be necessary if you plan on changing to a custom rom again.
rooted my s4 again,
twrp is finally working
but i cant flash the rom
Error executing updater binary in zip
anyone has an idea?
i allready downloaded the rom again but the zip is not broken
Are you using the latest version of twrp?
Yes 2.8.7.0

That error is caused because the recovery thinks the rom is not compatible with your phone.
Make sure your phone is compatible with the rom.
Or try these steps I found online:
1. Advance Wipe > Wipe cache, data, system, dalvik partitions.
2. Select ZIP file of your ROM and flash it.
3. You will get E:Error executing updater binary in zip (Don’t panic!)
4. Go to Reboot menu > Select Reboot to recovery.
5. After rebooting in recovery, flash the ZIP file of the ROM again WITHOUT WIPING.
Then it should work, according to the site I found it on.
The execution error indicates that the phone may not be supported by the ROM you're trying to flash..

Screen stuck on preparing to start.. starting app.. after flashing crdroid 6.0.1

I had rooted my phone by unlocking the bootloader using adb fastboot method, then flashing the TWRP revocery V2.8.7.0, and then flashing superSU v2.46.
After rebooting my yureka plus, and going to recovery it started cynogen recovery only, even though update cynogen recovery option was disabled.
So I flashed TWRP again and without rebooting again, just flashed crDroidAndroid-6.0.1-20160827-tomato.zip and GApps zip file from internal memory. The phone rebooted and worked fine after that..
but while playing a game the phone automatically rebooted and ever since have been stuck on Preparing to start.. Starting apps..
I had disabled the developer options because I thought it was working fine.
The phone is working behind the preparing to start screen.. I can hear the message notification and caller ringtone when someone messages or calls.
Any suggestions what I should do now? I have tried doing a factory reset from recovery but the problem persists.

Try flashing it with stock rom or simple wipe the whole system and cache from twrp from advance wipe option ( but backup first ) and again flash the custom rom u used previously.

It still opens in cyanogen recovery only, and there is no option for wiping dalvik cache or system. Since the usb debugging is of,f I cannot used cmd to flash twrp recovery again. By the way I still don't understand why twrp recovery is not loading.

I still have no idea why it got bricked. So after searching on google and youtube I came across this: https://androidmtk.com/download-yu-stock-rom-for-all-models . I followed the steps and now KitKat is running except launcher is not working, instead play store open's every time I try to go to home screen. So tried the nova launcher but that still doesn't work with home button, have to open through playstore->my apps, every time. But rest is working.

[Solved] Unable to boot into custom rom after device crash

So I my A2017G had RR-20170314 with TWRP 3.1.0-0 and AX7 R6 installed. Everything was working fine until today my phone rebooted while it was in my pocket. I didn't change anything before and haven't used it for some time and only noticed this through 2 short vibrations. Since then the phone refused to boot into system, TWRP was still accessible though. Three short blinks by the led directly after the bootloader screen and then the phone shut itself down.
Back in recovery I made a full backup and tried booting with deleting cache etc and installing the latest RR. Nothing worked.
When I went back to stock I was finally able to boot. Flashed TWRP 3.1.0-0 through axon7tool and installed RR again. And again only those 3 led blinks
Used "disemmcwp" to make sure write protection is disabled and noticed that when I rebootet the recovery got replaced by the stock one. Only if I enable write protection through "emmcwpenab" the recovery isn't replaced
Just checked the status of the bootloader and it still says unlocked.
I found two threads with a similiar issue but unfortunately nothing helped:
https://forum.xda-developers.com/axon-7/help/boot-recovery-boot-t3569364
https://forum.xda-developers.com/axon-7/help/3-flashes-reboot-phone-shuts-off-t3574324
Never experienced such a thing before. Any help is really appreciated ?
I'm really out of ideas what to do. And stock isn't really a permament solution
Are you using latest G bootstack? Is the device in dfu, or edl mode (check device manager on pc)?
Be very careful with that G version.
Yes since I was on RR before. Using the stock bootstack nor the one provided in the Los thread makes a difference.
Fortunately I'm not stuck in DFU mode. Booting to stock works, so does edl and twrp. But twrp only without using disemmcwp
I would try using older twrp. I've encountered this before but usually a reboot fixes it. I have not gone to twrp 3.1 yet, i think 3.0.4 was the one before.

Tried it with TWRP 3.04-1 and it's the same result.
Reboot diseemcwp -> recovery gets replaced by stock recovery after reboot
Reboot emmcwpenab -> recovery gets not replaced
In both cases I am unable to boot with a modified system or kernel.
Seems like the write protection is screwed up

If you disable write protection you inadvertently end up tripping dm-verity, which causes the device not to boot (security feature).
The reason you feel that disabling system write protection through TWRP causes TWRP to get overwritten by the stock recovery, could be because of the reboot rather than anything else.
I.e. When you install the stock system and reboot, the system overwrites the recovery partition, installing the stock recovery.
My suggestion:
- Make a backup.
- Wipe dalvik cache, cache, system, and data through recovery (under Wipe-> Advanced Wipe).
- Check that the filesystem of the partitions are ext4 (through the "file system" button under Wipe->Advanced Wipe menu), and change them if necessary.
- Reboot recovery.
- Don't swipe to allow system modifications.
- Install the stock bootstack, stock system (I'm assuming that you are using DrakenFX's image zips), and reboot.
- If it fails to install, just reboot recovery, and try to install once again.
Let me know if this works for you.

Already did those steps but instead of using DrakenFX's files I used the official stock zip.
Shouldn't make a difference right?
Gonna try it once more...
Edit:
I'm stock now, TWRP installed without allowing system modifications.
Edit2:
Just rebootet and the recovery is gone again. This happened after I dlashed the recovery again after reverting to stock.
Edit3:
So what I tried so far after reverting to stock after each fail:
- flash SuperSU 2.65 -> unable to boot
- flash SuperSU 2.97 -> unable to boot
- flash Magisk 11.6 -> boot successful, Magiks installed and showing root but unable to request root permissions
- flash latest Los -> unable to boot
- flash latest RR -> unable to boot
- flash latest tool to disable dm-verity (from TWRP thread: https://build.nethunter.com/android-tools/no-verity-opt-encrypt/) -> unable to boot
- flash AX7 R1 -> unable to reboot
Did the above steps with allowing system modifications and without.
Same for rebooting with disemmcwp and reformatiing partitions.
Tried using the universal bootloader from Los thread and still wasn't able to boot except using the stock rom.
I'm really out of ideads what I could try next.
Recovery seems to stick for now.
Could it be that the problem is not dm-verity but something else?
When I rooted the device I encountered no problem with that security mechanism. Custom roms and kernels worked as well without ever having to worry abou that.
Finally managed to boot into RR!
Here is what I did:
1. Went back to B10
2. Relocked bootloader
3. Booted into system -> developer settings -> Oem Unlock
4. Unlocked bootloader
5. Flashed recovery through fastboot
6. Booted directly into TWRP (when I did a restart it was overwritten immediately that's why I booted directly into it one the second try)
7. Allowed system modifications inside TWRP and flashed SuperSU 2.65
8. Successfully booted into system and had root
9. Flashed Universal Bootloader and Modem from Los thread
10. Flashed RR + Gapps
I really don't know which step the crucial one was but I hope if someone else manages to get into the same situation as I did those steps will help.
Thank you guys for helping me out

Recovery crash when flashing custom ROM

Hi everyone,
I posted this thread in general troubleshooting category and after some advice, I decided to post it in the S4 section.
I was since 3 years on custom ROM (CM and Lineage OS) and due to substratum, I had a bootloop.
My problem is quite particular, after a total clean (wipe and format cache,system,data, dalvik cache) of my device and flashing the stock ROM, custom recovery cause me some trouble.
Whatever I try (CWM touch 6 or TWPR 3.1.1), I can't flash custom ROM (Lineage OS 14.1), TWPR or CWM crash 1 second after the flash command and reboot, with disable touchscreen and even by using old navigation way and try again, same problem.
Tried also to disable file signature check but no effect.
Quick summary about what I did:
- Device: Samsung Galaxy S4 (GT-I9505)
- ROM stock used: I9505XXUHOJ2 ( the build on which is based the CF-Root file I used) and Bulgarian version due to mistake.
- I tried on these two ROM with in the two cases, no patch or Samsung ROM update made.
- Tried to install CWM by ROM Manager and ODIN (v3.09)
- TWPR installed by TWPR App using file in .img and not the second option (tar.img) for LTE Internationnal Qualcomm.
-Checked the root before last attempt with root checker and it was ok.
- Made 4 times already the clean and Stock ROM flash to clean recovery and try another way to install it (never had error after recovery install).
Actually I'm on the OJ2 Rom with update and patch delivered by Samsung with classic method.
In advance thanks for your help and I really hope it's not too serious.
By the way, sorry for my english, it's not my native language
Try flashing the stock ROM from sammobile.com or updato.com, don't root, use Odin 3.07 to flash the tar version of TWRP 2.8.7, try flashing a custom ROM.
Thx for the help/advice
Just to be sure, my stock ROM is actually from up updato.com but due to the patch and Samsung update I'm now on HPK2.
Here the detail of my stock ROM
https://image.noelshack.com/fichiers/2018/05/4/1517503670-screenshot-2018-02-01-17-43-00.png
(the integrated image link option made it as large as the moon so I prefer a simple link)
TWPR 2.8.7 is still efficient or another version would be better ?
If yes, I will try in the hour and I will give you news as soon as possible
EDIT: After some research, TWPR 2.8.7 jfltexx is not avaible in .tar , only .img and impossible to find it on net...
But 2.8.6 and 2.8.4 are avaible in .tar and 3.0.0 in .img.tar , which one is the best ?
I suggested 2.8.7 because Ihave used it in the past and it was very stable. Try a newer tar version. It's really just to see if the phone will take TWRP and boot it.
Whatever I try (TWRP 3.0.0 and 3.0.1 in .img.tar for jlftexx)
Odin (v3.07) do the job , my phone reboot as normal.
But when I shutdown it and lauch in recovery by manual way, got during a micro seconds the android logo of loading and intant "No commands " and I end on the stock recovery.
Edit: I will try the same method with Odin using CWM tar (never had problem with it before this day)
Same thing with CWM-v6.0.4.7-Touch-GT-I9505.tar
Android loading logo and "No command detected"
Problem solved
Well, I don't know how I made a sucess but it seems the "wild" method worked.
So here is the list of things I did in case somepne got the same trouble
Put your Zip file on SD AND Internal Memory (in case)
All the Zip files I used where on my internal storage during this procedure.
- Download mode:
uncheck Auto Reboot in Odin
flash TWRP3.0.1.0 jlftexx.img.tar with ODIN in admin mode
turn off device after flash ended
Obligation or the stock recovery will return automatically !
Lauch device in recovery mode:
If it's TWRP good news, slide to confirm modifications.
Recovery mode:
-Wipe --> Advanced Wipe--> Select Cache, Dalvik Cache, Sytem and Data (never check internal and SD storage)
I tried by mistake without wiping dalvik cache, and got no boot after 5 minutes so i made it again with all the wipe above
-Install --> Flash zip of the rom and Gapps (got an error at zip signature check on the ROM so I flashed after uncheck this option)
-Reboot --> System
Let your device launch on the new rom, set the basic parameters and after, if you want, return in recovery to flash the SU addon for root (got also zip sugnature fail so I ahd to uncheck it again)
Hoping no one will ever had the same problem but in case, I share my solution
Thanks again for help

Did Factory Reset in Custom Rom now i have a TWRP Bootloop. (Mediatek)

Hello Guys it´s me again. (i know im annoying )
Well, i did a Factory Reset in dotOS and it Rebooted into TWRP.
However, Normally a Phone would then Perform the Action in the Recovery but in this Case it did not do it. So i Reflashed the Rom.
After that it Rebooted into TWRP again. I Tried to Access the Bootloader with Vol Down + Power. That also Booted into TWRP. After that i Selected Bootloader in the TWRP Reboot Options. That Booted the Phone into the Mode where i Flashed the Recovery but it did not Give me the Options like META MODE, FACTORY MODE etc, when i tapped the Volume Buttons. Only a Black Background with White text Saying :
> FASTBOOT mode...
> device unlocked
I Tried to Restore my Stock TWRP Backup but that did not Solve the Issue. I also tried to Reflash dotOS but same issue.
What else Can i do to get this fixed ? I never had a Problem Like this on any Sony or Samsung Device i tinkered with. Thats why im asking that much.
@Marc_Xperia Do not forget to install no-verity-opt-encrypt zip file or simple disable *system verifier* in kernel ramdisk.

It's very simple
-boot into recovery
-wipe
-advanced wipe
-clear / format cache & dalvik
-reboot _choose reboot recovery
-select mtp file transfer mode in twrp
-push LATEST* magisk zip
-push clean copy of dotOs
-then do FULL WIPE (all) but not your sd or internal sd/data
-install first dotOs zip
-install magisk zip
-wipe cache
-reboot
* If you fail check what is selected under the mount section & report back
If problem persists flash an older version of recovery using SPflashtools and then older version of dotOs with magisk
_do full wipe first
#some new recoveries had errors so make sure you are running ABSOLUTE latest or OLDEST version of twrp
# I haven't tried the last or latest version of dotOs yes ( older versions worked 100%)
